Thank you for consulting the Welsh Government on the Vale of Glamorgan Council Replacement Local Development Plan (LDP) – Deposit Plan. It is essential the authority is covered by an up-to-date LDP to give certainty to local communities and businesses and provide a robust basis for decision making.
Without prejudice to the Minster’s powers, the Welsh Government is committed to assisting Local Planning Authorities (LPAs) minimise the risk of submitting unsound plans by making comments at the earliest stages of plan preparation. The Welsh Government looks for clear evidence that the plan is in general conformity with Future Wales: The National Development Framework, aligns with Planning Policy Wales (PPW) and the tests of soundness, as set out in the LDP Manual.
National planning policies are set out in Planning Policy Wales (PPW) Edition 12 and seek to deliver high quality, sustainable places through a place-making approach (the LDP should ensure it takes into account any further iterations of PPW prior to the examination). The implementation of the core policy areas in PPW, such as adopting a sustainable spatial strategy, appropriate housing and economic growth levels, infrastructure delivery and place-making, are articulated in more detail in the LDP Manual (Edition 3). We expect the core elements of the Manual, in particular Chapter 5 and the ‘De-risking Checklist(s)’ to be followed. Failure to comply with these key requirements may result in unnecessary delays later in the plan making process. The development planning system in Wales is evidence-led and demonstrating how a plan is shaped by the evidence is a key requirement of the LDP examination.
After considering the key issues and policies in Future Wales, the Welsh Government is of the opinion that the Replacement Deposit Plan is in general conformity with Future Wales: The National Development Framework. Specific comments are set out in the Statement of General Conformity (Annex 1 of this letter). Annex 2 highlights a range of issues that need to be addressed for the plan to align with PPW and the DPM. Collectively, our comments highlight a range of issues that need to be addressed for the plan to be considered ‘sound’ as follows:
Annex 1 – General Conformity with Future Wales
• No significant concerns
Annex 2 – Core matters that need to be/have been addressed (PPW and the DPM)
• Spatial Strategy and Primary Settlements
• Housing and Economic Growth Levels – Regional Collaboration
• Maximising Affordable Housing Provision
• Delivery & Implementation – General
• Gypsy and Travellers
• Renewable Energy
• Minerals
• Best and Most Versatile Agricultural Land (BMV)
• Welsh Language

I would urge you to seek your own legal advice to ensure you have met all the procedural requirements, including the Sustainability Appraisal (SA), Strategic Environmental Assessment (SEA) and Habitats Regulation Assessment (HRA), as responsibility for these matters’ rests with your authority. A requirement to undertake a Health Impact Assessment (HIA) arising from the Public Health (Wales) Act 2017, if appropriate, should be carried out to assess the likely effect of the proposed development plan on health, mental well-being and inequality.
My colleagues and I look forward to meeting you and the team to discuss matters arising from this response.
Yours sincerely,
Neil Hemington
Chief Planner Welsh Government

Annex 1 - Statement of General Conformity
The Welsh Government is of the opinion that the Vale of Glamorgan Council Replacement Local Development Plan (2021-2036) Deposit Plan is in general conformity with the National Development Framework: Future Wales, as set out in paragraphs 2.16 – 2.18 of the Development Plans Manual (Edition 3).
There is a joint position statement on the relationship between Bridgend, Cardiff and the Vale of Glamorgan (BP20A), which considers population growth, migration patterns, housing completions, employment characteristics, demographics, commuting and transport links between the three adjoining authorities. The Welsh Government supports the principle of this work which demonstrates how change in the Vale of Glamorgan relates and complements growth in adjoining local authorities. This approach illustrates a good mechanism for other local authorities to follow.
Reasons
Future Wales places emphasis on the development of National Growth Areas in a sustainable manner. Growth areas must be sustainably planned, reduce the need to travel by car, encourage walking and cycling (active travel), maximise public transport usage and incorporate green infrastructure. Growth areas must embed these principles within a wider regional consensus, focussing on the opportunities they bring to promote social and economic benefits across a broader geographical area. The Welsh Government supports sustainable growth in National Growth Areas to respond to the climate change and biodiversity emergencies, making the best use of resources.
Policy 1 and Policy 33 of Future Wales states that Cardiff, Newport, and the Valleys will be the main focus for growth and investment in the region. The strategic diagram (p163) also identifies the Vale of Glamorgan within the National Growth Area. The Vale of Glamorgan RLDP, specifically BP20A, provides robust evidence on the interrelationship and key issues with adjoining authorities, including their interaction and how they have shaped and influenced the scale/location of growth in the RLDP. This is set out in the three Joint Position Statements (JPSs).
BP45 ‘Regional Assessment of Future Growth and Migration for the Cardiff Capital Region (CCR), May 2024, provides further evidence on how the scale of growth indicated for the region has shaped the scale of future economic growth within the Vale of Glamorgan. This results in a higher level of employment growth in the Vale of Glamorgan primarily to increase self-containment and reduce out-flows to adjoining urban areas. Two key areas for future economic growth are identified at Cardiff Airport/Bro Tathan Enterprise Zone and Aberthaw Power Station.
The result is a Sustainable Transport Orientated Growth spatial strategy focusing on the Cardiff – Bridgend railway line and A48 corridor, with the key settlement for growth at Barry, followed by service centres on public transport corridors. On balance, the Welsh Government considers the Deposit Plan is in general conformity with key policies in Future Wales namely (not exhaustive):
Policy 1: Where will Wales grow
Policy 2: Shaping Urban Growth and Regeneration – Strategic Placemaking
Policy 6: Town Centre First
Policy 10: International Connectivity – Cardiff Airport
Policy 12 Regional Connectivity
Policy 33: National Growth Area – Cardiff, Newport and the Valleys
Policy 36: South-East Metro
Future Wales brings a new perspective that all LDPs have to embrace on how each LDP sits within the region as a whole and the relationship to other LDPs, in essence, a strategic approach to cross boundary relationships. There is evidence to support that approach in advance of an SDP. 4

Annex 2 – Core matters that need to be addressed (PPW and the DPM)
Spatial Strategy - Location of Growth
The Council tested 4 spatial options:
Option 1 – Continuation of the adopted LDP growth strategy
Option 2 – Dispersed Growth
Option 3 – Focused Growth
Option 4 – Sustainable Transport Orientated Growth
The Council has chosen Option 4: Sustainable Transport Orientated Growth for its Deposit Plan. The strategy seeks to locate most of the new growth in those settlements well served by existing/proposed rail infrastructure along the Vale of Glamorgan/Penarth branch lines. This will encourage and maximise the use of sustainable transport modes in the plans designated Strategic Growth Area (SGA). The SGA encompasses most of the Council’s largest and more sustainable settlements and the Council considers that focussing development here will reduce the need to travel and will co-locate housing with employment opportunities, services, and community facilities.
With a significant proportion of the Council’s brownfield land already developed/committed, there are limited opportunities for brownfield development moving forward. The existing land bank is stated as 5,140 dwellings (land supply 3,837 + windfall assumptions 1,303), to meet a proposed housing requirement 7,890 (provision 8,660). The authority has allocated 3,520 dwellings on new sites (Policy SP6, Table 2). As a result, the plan has adopted a predominantly greenfield strategy allocating the majority of new development on five key sites (Policy HG1, Sites KS1-5 totalling 2,278 dwellings) well-connected edge of settlement sites, close to existing or proposed rail stations. We note the Council has used TfW data in the site assessment process to assess sites and their proximity to transport nodes. The remaining sites are mainly ‘rolled’ forward from the adopted LDP. The Welsh Government supports the spatial strategy, which accords with Planning Policy Wales (PPW) and is in general conformity with Future Wales.
Spatial Strategy - Primary Settlements
The Council’s settlement hierarchy allocates circa 92% of all housing development (committed and proposed) to settlements in the top three tiers of the hierarchy. The Welsh Government does not object to this approach. The recognition that Culverhouse Cross with few facilities on site and the presence of BMV Land, the expectation for limited growth (paragraph 6.14 & 6.15) is welcomed. Similarly, it is noted that Wick benefits from a primary school and has some scope for future growth, albeit in keeping with the scale and accessibility of the settlement. The Welsh Government is content that the scale of growth reflected in these two locations will reflect the availability of local facilities and services.
The Level of Growth - Homes and Jobs
The Deposit Plan (Policy SP1 & SP6) makes provision for 8,660 homes to deliver a housing requirement of 7,890 new homes (526 p/a) over the plan period 2021-2036, of which a minimum of 3,070 homes will be affordable. The flexibility allowance proposed by the Council is 9.8%. The delivery of new jobs is for 5,388 over the plan period (Policy SP14).
Homes: The 2018 WG Principal Projection results in a requirement of 431 units p/a, or 6,465 units over the plan period. The housing growth proposed in the plan (requirement) is around +1,425 units (22%) above the WG 2018 principal projection, the provision being +2,195 (34%) above. The Council consider the 10 year average housing completions to represent a more realistic level of growth to deliver the key issues the plan is seeking to address. The Council considers that a lower level of growth (2018 projection) is not appropriate because the projections do not take account of 5

any policy decisions and were prepared in advance of the Covid-19 pandemic with implications for migration patterns and fewer jobs proposed.
BP8A (November 2025) considers the latest 2022 Welsh Government population and housing projections, noting they are higher than the 2018 based projections. The projections for the Vale of Glamorgan show significant variation in internal migration in particular which the Council considers should be treated with caution. The projections are trend based and are affected by specific factors that may have occurred within the previous 5 years. The 5 years in question included a period of high housebuilding associated with a newly adopted LDP, as well as the Covid 19 pandemic, where many students returned to home from term-time addresses and re-registered with GPs in the Vale.
Given the fluctuation in recent migration figures, the Council consider longer-term trends are more appropriate, and it is noted that the population change identified in the 10-year migration variant is of a similar level to that proposed under the RLDP projection. In conclusion, for the reasons identified above, despite the updated projections, the Council considers the RLDP housing requirement continues to represent a robust basis to deliver a sustainable and deliverable level of growth over the plan period. The Welsh Government does not object to the scale of housing contained within the plan.
The demographic evidence (February 2023, Edge Analytics) tested 12 growth scenarios comprising: demographic-led, dwelling-led, and employment-led scenarios. The preferred housing requirement is based on a 10-year dwelling-led scenario (526 dpa) that would result in a population growth of 9.7% over the plan period with an annual net in-migration of 1,009 persons. The Council considers this level of housing growth is deliverable with a large proportion met through existing commitments (51%) and a jobs total (4,875 jobs) that broadly aligns with the level of new jobs forecast in the Employment Land Study (5,338 jobs). Moreover, the scale of growth is considered by the Council to be compatible with Future Wales and the role the authority plays within the wider southeast region. With inward migration to the Vale of Glamorgan from Cardiff expected to slow as Cardiff’s strategic sites deliver higher levels of housing and with employment opportunities in the Vale co-located with housing sites, there are further opportunities to reduce the high levels of out-commuting into Cardiff. Overall, this approach is proposed by the Council to deliver a level of growth that is balanced with the emerging Cardiff LDP and wider southeast region. The Welsh Government does not object to the level of growth proposed in the plan.
We note that historic completion rates in the Vale of Glamorgan have fluctuated considerably over recent years. The past 10-year (2011-2021) average completion rate is 526 dwellings p/a. This has been exceeded over the last 5-years (2016-2021) with 698 dwellings constructed p/a. Build rates in recent years are in part attributed to the delivery of the current adopted LDP strategy that has more of a ‘rural settlement' focus, with multiple sites across many settlements being built out. Replicating this approach going forward (10,470 dwellings) would not comply with FW/PPW in terms of sustainable development and transport, potentially adversely impacting on Cardiff’s growth strategy. On this basis, the Council considers that achieving 526 dwellings p/a in the preferred 10-year dwelling-led scenario is sustainable and deliverable and would provide a level of job growth (5,338 jobs) that is balanced with the housing requirement. The Welsh Government does not object to the level of housing proposed in the plan but demonstrating delivery of the key housing sites will be essential.
The Welsh Government notes that BP0A identifies small and large windfalls, based on historic trends of 53/yr and 80/yr respectively. Also, the large windfalls are not included in the first two years of the trajectory, as per the DPM. A non-delivery allowance of 5% is identified, which reflects local characteristics in the Vale of Glamorgan. A flexibility allowance of 9.8% has been factored into the provision. The Welsh Government supports this approach, although whilst Appendix 1 contains a housing trajectory, there is no table to mirror that of Table 21, DPM. This should be included in Appendix 1. 6

Jobs: The Council’s 10-year dwelling-led growth option results in a requirement for 4,875 new jobs (325 p/a) over the plan period. This broadly aligns with the projected growth for 5,338 (355 p/a) new jobs in the Employment Land Review (BP12) and as set out in Policy SP14.
The level of employment growth proposed (5,338 jobs) over the plan period is below the target in the currently adopted plan (7,610-10,610 jobs). The lower target is considered by the Council to more accurately reflect the cohort of working aged people in the Vale of Glamorgan and would support a continuation of long-term housing delivery trends that takes into account lower housing growth post-recession and a shorter period of historically high dwelling completions (2016-2021). The Welsh Government does not object to the level of job growth proposed in the plan.
In summary, (and subject to the above clarification), the Welsh Government has no significant concerns with the level of homes and jobs proposed in the plan, which is in general conformity with Future Wales.
Affordable Housing Provision
The Local Housing Market Assessment 2023 (LHMA) (BP10B) calculates affordable housing need over the replacement plan period using the ‘policy neutral’ Welsh Government 2018 Principal Projection and the preferred growth option. The LHMA provides the latest evidence on affordable housing need, identifying a net annual need for 1,075 affordable units per annum for the next five-years and a further 154 units per annum over the following 10 years (BP10B, Executive Summary), resulting in a requirement for 6,915 affordable homes over the plan period (461 p/a) with a tenure split of 65% social rent and 35% intermediate. The Welsh Government note that the RLDP housing requirement is higher than the 2018 projections. Accordingly, to take this into account the affordable housing need for the RLDP is 502/yr which equates to a need of 7,530 over the plan period (RLDP, paragraph 6.116, Table 4).
Policy SP7 identifies a target of delivering a minimum of 3,070 affordable homes, the housing need being across all 13 Housing Market Areas, albeit it is more acute in Barry, Penarth, and Llantwit Major for 1-bed properties. The Welsh Government notes that most of the new housing development (51%) is proposed in the Key Settlement of Barry and Service Centre Settlements, which include Penarth and Llantwit Major.
The Welsh Government has no significant concerns regarding the relationship between the LHMA and the Deposit Plan.
Affordable Housing Led Sites
To deliver additional affordable housing above that which market led housing can provide, the authority proposes (Policy SP3 & HG4) to permit small scale affordable housing-led developments that provide a minimum of 50% affordable housing on sites up to 25 dwellings in minor rural settlements and 50 dwellings in primary settlements. The principle of this approach is supported.
Paragraph 6.137 of the plan states:
“Policy HG4 makes provision for affordable housing-led sites in locations outside the Strategic Growth Area. These sites, which are allocated for a minimum of 50% affordable housing, are included within the settlement boundary.”
The reference to being within the settlement boundary is not referenced in policy HG4. It would be beneficial to either include such a reference or demonstrate that settlement boundaries do include those sites listed in policy HG4 for clarity.
These sites must be in addition to the market housing led requirement and identified in the LDP. This policy approach is justified by the high level of affordable housing need evidence by the LHMA and must be accompanied by additional control over the land by the local planning authority to 7

ensure effective delivery. Evidence should include ownership of the land, a binding legal agreement where the land is in private ownership or a resolution of the council to use compulsory purchase powers. RLDP, paragraph 6.133 references to such controls, however, should such controls be contained within the policy?
Affordable Housing Exceptions Sites
Policy HG5, states 100% affordable housing exception sites can be located outside a settlement boundary where they comply with PPW/TAN2 and any threshold/policy requirements set in the Deposit Plan. The Welsh Government supports this approach.
Employment Land
The Council’s Employment Land Study (BP12, March 2023) identifies a requirement for 67.80ha of employment land, which includes a 5-year buffer. The requirement is based on rolling forward past trends (over 25 years) and is of a sufficient scale to meet the 5,338 jobs forecast. However, Policy SP14 identifies employment land allocations totalling 182ha, which is an increase of around 114ha above the employment land requirement. The sites that make-up this supply are largely major employment allocations that attract significant regional inward investment at Cardiff Airport and Bro Tathan Enterprise Zone totalling 127.85ha (70%) of the total provision. The Welsh Government does not object to the over-provision of employment land in the plan. The Enterprise Zone designation must be identified and the allocations within it (SP14: 1-3).
Delivery and Implementation
PPW and the DPM (Chapter 5) contain guidance on the requirements in respect of the delivery and implementation of plans. The Deposit Plan should set out site-specific details for Key Sites that includes general phasing timescales, key infrastructure requirements, placemaking principles (including concept / schematic masterplan frameworks), constraints, and developer requirements, where appropriate. We note the Deposit Plan has included emerging master planning/infrastructure work on key sites.
The phasing, timing, funding, and delivery of Key Sites will be critical to ensure the plan delivers the scale of growth required over the plan period. This includes the relationship between the two Key Sites in St Athan (KS4 and KS5) totalling up to 1,150 units and the delivery of a new rail station in St Athan to meet the objectives of the strategy and encourage a modal shift to more sustainable forms of public transport.
The development sites may also impact on the trunk road network, in particular the M4 J34 and there will need to be a suitable level and form of traffic assessment to accompany the plan. (The transport case may consider the South East Wales Traffic Model as part of any masterplan impacts on the Strategic Road Network (SRN) (Wales Regional Transport Models | TfW)). The Council will also need to demonstrate that all housing components are deliverable through a housing trajectory prepared by the Council and Housing Stakeholder Group. Statements of Common Ground for key allocations, especially those that have ‘rolled over’ from the adopted plan, would be advantageous to demonstrate the sites are deliverable in the timescales set out.
The Deposit plan is supported by a high-level affordable housing study and site-specific viability appraisals for Key Sites. All viability work and must be prepared in conjunction with the Viability Steering Group and site-specific promoters.
It will be for the Council to justify deliverability supported by robust financial viability.
Gypsy and Travellers
The Gypsy and Traveller Accommodation Assessment GTAA (June 2022, approved June 2024) identifies a total need for 11 pitches over the plan period up to 2036, of which 9 pitches are ‘immediate’ by 2026. WG note that 4 pitches have since gained planning permission, reducing the remaining need over the plan period being 7 pitches. 8

Policy SP9 identifies a site at Llangan (0.76Ha) to accommodate the 7 pitches needed. It will be for the Council to demonstrate the appropriate site selection assessment process has been followed and that the site complies with requirements in PPW (4.2.35), Circular 005/2018 (paragraph 35) any relevant guidance and the DPM (5.80-5.85) to allocate a deliverable site in the plan period. The views of the relevant statutory bodies must also be agreed with no outstanding objections to the delivery of the site. The Welsh Government has no objection in terms of meeting the numerical need for gypsy traveller accommodation.
Renewable Energy
Future Wales: The National Plan 2040 identifies Barry as a District Heat Network (DHN) Priority Area. The Renewable Energy Assessment (BP15) explores the opportunity for a DHN using waste heat from Barry Biomass, but as there is some uncertainty on the future of the plant, the study concludes there is considerable risk to using the plant as a source waste heat. Could the Council provide an update on alternative options for a DHN in Barry?
It is welcome that the Renewable Energy Assessment (REA) has considered BMV policy, specifically for solar PV, and use of the Predictive ALC Map. The assessment has only considered non-BMV land (Subgrade 3b, Grade 4 and 5). The assessment would benefit from referencing the clarification provided in the DCPO letter of 1st March 2022 in respect of solar PV and BMV agricultural land for completeness.
The study identifies that in the Vale of Glamorgan solar development is more suitable than wind energy because of the flight path of aircraft in the south of the County Borough. However, there are some opportunities for wind sites, but these are likely to be small (<10MW) where aviation risks are lower and there is some grid access. Conversely, there are large expanses of land suitable for solar areas (>10MW) to the West of the County Borough, where there is little existing development. The study identifies 20 large-scale solar areas but recognises that grid constraints may impact the ability of sites to come forward.
Solar and wind search areas (where appropriate) below the 10MW Developments of National Significance (DNS) have been identified (Policy CC3). The plan also includes a criteria-based policy for all renewable energy proposals, particularly wind development, under 10MW (Policy CC4). Policy CC3 makes reference to adhering to the criteria in Policy CC4. However, would it not be the case that if search areas have been identified in Policy CC3 have they not already met the criteria? If they would not, should they be identified in the first place? Clarity would be beneficial. The Welsh Government supports the approach but seeks clarity on the point raised.
The Welsh Government notes the proposed search areas for wind energy near Morfa Ystrad Owen/Nant Rhydhalog, according to the Peatlands of Wales Evidence Score Map, the search area includes areas of peatland (Evidence Score 4). The site is also a SINC. This raises concerns as to how the inclusion of this search areas meets the policy test in PPW 6.4.15, 1a and 1b (Stepwise) regarding avoidance of irreplaceable peatland habitats and PPW 6.4.34.
Policy CC4 refers to Developments of National Significance (DNS) in 6.344 and 6.346. This should now refer to Strategic Infrastructure Projects (SIP) which replaced DNS.
Minerals
The Regional Technical Statement (RTS 2nd Review) identifies a nil apportionment for land-won sand and gravel provision in the Vale of Glamorgan. The Welsh Government policy clarification letter (dated 11 November 2021) identifies a surplus of 1.68mt of crushed rock. As there is a surplus of crushed rock reserves and a lack of sand and gravel production in the Vale, no specific allocations are required in the replacement plan. It is unclear whether a Statement of Sub-Regional Collaboration with adjoining authorities in the Cardiff City sub-region been agreed, or does the latest Position Statement (July 2022) explain how any shortfall will be met across 9

the region, particularly for crushed rock, of which the Vale has a surplus? Clarification would be beneficial.
BMV Agricultural Land
The Welsh Government has engaged with the Council for land quality advice, survey advice and ALC survey validation for candidate sites. The LPA has produced a specific topic paper on BMV policy application. BP23A. The Deposit RLDP allocates 188 hectares of housing land, 5.62 ha is identified as BMV land (under 3% of total housing allocations). The RLDP:
• Has sought to avoid BMV land wherever possible;
• Uses the Predictive ALC Map as a core evidence layer to inform: The spatial strategy;
• Settlement hierarchy decisions; and
• Candidate site assessments.
•
• Directs strategic growth to areas with least BMV land
• Removes or avoids allocations where BMV impacts were significant or unjustified.
• Quantifies total BMV loss and demonstrates it is minimal (5.62ha) and proportionate at plan level.
• Applies a sequential approach through: Preference for brownfield and non-BMV sites;
• Replacement of higher-BMV sites with lower-grade alternatives where possible.
•
• Requires site-specific ALC surveys to verify actual land quality before allocation.
• Demonstrates that allocated BMV land is: Often small, fragmented, or constrained;
• Sometimes previously disturbed or incapable of being farmed differently from surrounding lower-grade land; and
• Necessary to deliver the Plan’s housing strategy where reasonable alternatives are unavailable.
•

In conclusion, the Welsh Government consider the Authority has demonstrated a sensible and pragmatic approach to considering BMV loss in the context of national planning policy, and on that basis no objection is offered.
Green Infrastructure
Policy SP19 should explicitly reference the need for development to be accompanied by a Green Infrastructure Statement.
PPW12 requires decision makers to apply the step wise approach to GI, with enhancement secured at every stage where possible, there is no distinction made between the quality of the GI assets – the qualification in the policy statement that states proposals will incorporate measures that protect and enhance high quality multi-functional green infrastructure should be redrafted to remove the quality reference. The need to avoid an impact in the first instance should also be explicitly incorporated into the policy.
Criterion 1 (Policy SP20) should be redrafted – the stepwise approach in PPW 12 6.4.15 1a - does not distinguish between relative ecological value – the avoidance step applies to biodiversity in its widest sense (i.e. the variety of species and habitats and their abundance) and ecosystem functioning.
Welsh Language
There is limited reference to the Welsh language in the plan, either potential adverse impacts arising through development, or mechanisms via a policy framework to support and grow the use of the language. There are references to a number of Welsh-medium schools (3.26) and the increase in the number of people able to speak Welsh according to the 2011 census (3.52) but there is no mention of the authority's Welsh Language Strategy or promoting or cross-referencing to the aims of 10

Cymraeg 2050: A million Welsh-speakers. Paragraph 6.81 of the plan refers to development north west of Barry:
“Land at North West Barry is allocated for a residential development of up to 376 dwellings and public open space. The site is in a sustainable location on the edge of the Barry, a key settlement, in a location that is well served by services and facilities, including a major supermarket, GP surgery, community centre, three primary schools (English Medium, Welsh Medium and Church in Wales) and two high schools (English and Welsh Medium) all located in reasonable walking distance. There is an active travel route along Port Road West, bus stops in close proximity providing buses to Llantwit Major, Cardiff and the centre of Barry. Barry station is 1.3 miles from the site entrance.”
There is no mention that the Council want to undertake a Welsh Language Impact Assessment (WLIA) so there appears no attempt to measure the impact on the Welsh schools resulting from housing development? Could the Council clarify if such implications have already been covered in the WLIA for the plan, ISA, or are any specific policies necessary?

This is very important, developments must allow and improve connectivity for species across the wider landscape - wildlife corridors etc. Avoiding sensitive sites by a good buffer margin to avoid disturbance by development.

I support this in principle but feel it is too vague and weak. The council should be pushing for protection of species beyond statutory requirements and hold itself to a higher standard. There are always ways that local/on site nature based solutions can be incorporated and the statement saying off site measures can be considered is too weak and gives developers too much scope to bypass their requirements.

The HBF suggests that the words 'functionally related' should be removed from the bold text at the end of the policy. Although the principle of this final paragraph is supported, the flexibility which it provides to developers is, in part, removed by the wording above. It is accepted planning practice that where something can not be provided on site, an off-site alternative can be acceptable, subject to the appropriate controls. However, limiting this to 'functionally relates' is onerous and unnecessary to achieve the aims of the policy.

Policy SP20 states that “Where development is considered appropriate and the on-site delivery of nature-based solutions is not feasible or sufficient, planning obligations and/or conditions will be used to secure and maintain compensatory off-site habitats and measures that are functionally related to the assets within the site and contribute to the wider local nature recovery priorities.”

The proportionate approach to biodiversity mitigation and compensation, that provides allowance for planning obligations towards off-site habitat improvement and maintenance is consistent with Chapter 6 of PPW and therefore meets the first test of soundness (Does the Plan fit?). It is essential that options are retained to provide biodiversity mitigation off site as well as on site.

The Green Infrastructure policies are welcome but overlook building-dependent species such as bats and red-listed endangered birds such as swifts, house sparrows and house martins.

Wales does not yet have planning guidance for these species but England has guidance based on British Standard BS 42021 for Integral Nest Boxes.

Therefore, please implement the equivalent of England national planning policy guidance (NPPG) Natural Environment 2025 paragraph 017 (https://www.gov.uk/guidance/natural-environment ), with regard to at least one swift brick per dwelling on average for new developments as these are a universal nest brick for small bird species, not included in quantitative biodiversity calculations so a separate policy is needed.

Key text to include from the England NPPG is as follows:
"Developments should include integrated nest boxes (commonly known as swift bricks) where possible, with the general aim across a development of a minimum of one nest box per unit. Nest boxes can provide important habitat for other species as well as swifts, such as starlings and sparrows.
Extensive guidance is available on wildlife friendly features, including the National Design Guide and National Model Design Code which illustrate how well-designed places can support rich and varied biodiversity by facilitating habitats and routes for wildlife. More specific support for the selection and installation of swift bricks can be found in the British Industry Standard BS 42021:2022 the Future Homes Hub Homes for Nature Guidance, and the RSPB’s Guide to Nestboxes. "

Please add, as house martins are a significant species in the Vale of Glamorgan with good availability of vegetated and waterside areas for foraging:

"Artificial nest cups for house martins may be specified as an alternative to swift bricks, where recommended by a suitably qualified ecologist."

Please also add the following, to ensure effective implementation:
"Post-construction stage confirmation of installation is required through photographs or verification by a suitably qualified ecologist."

Existing nest sites in buildings should be protected and retained where possible, and equivalent mitigation provided where this is not possible.

include text that improves biodiversity, natural spaces and green areas with the potential for food growing on new development sites. We have strong evidence that new sites are not providing as they should and local authorities have a duty to ensure they do.

There needs to be more recognition that Food growing enterprises and projects have multi faceted benefits including contributing to local authority Section 6 duty under the Environment Wales Act (net biodiversity gain) and contributing to the areas Wellbeing goals, Contribution to net zero by 2035 .
“The Vale of Glamorgan Biodiversity Forward Plan (BFP) sets out how the Vale of Glamorgan Council shall meet its obligations under section 6 of the Environment (Wales) Act 2016 to demonstrate how the Local Authority will “seek to maintain and enhance biodiversity in the proper exercise of their functions and in doing so promote the resilience of ecosystems”.”
Social Farms & Gardens and Keep Wales Tidy are meeting regularly with a Welsh Government forum, to work on the challenge of the poor delivery of spaces for biodiversity on new school sites and in new housing developments. When visiting new school sites to deliver ‘Local Places for Nature’ packages, we find that many of them are devoid of spaces for nature. The Council’s duty under section 6 of the Environment (Wales) Act 2016, is to make sure biodiversity and sustainability are core themes of delivery. Policies in the LDP should look to improve the delivery and management of new development to ensure spaces for nature are delivered to the high standard that is needed.
The Vale’s commitment to sign the Place Making Charter means it agrees to promote people and communities in the planning, design and management of new and existing places. The Vale’s significant affordable housing need and investment in new schools across the plan area, is an opportunity to achieve this. The LDP should make reference to the requirement for high quality natural spaces to serve biodiversity and peoples’ health and wellbeing on new development sites that are to be used to house and school our communities, especially in areas that are have low levels of nature, health and other inequalities. The effectiveness of delivery and management of these spaces should be monitored for compliance.

We also ask for the RLDP to provide wording within this or another policy or to provide guidance that encourages communities to think about including food growing sites in their Place Plans. Where will their food come from if the supermarkets do not have any available to them due to various world events and climate change?

Thank you for consulting Natural Resources Wales (NRW) on the Vale of Glamorgan Replacement Local Development Plan (RLDP) Deposit Plan, which we received on 28 January 2026.
We have reviewed the deposit plan and published documents and have recommendations on matters relating to coherence and consistency. We advise these are addressed prior to submission of the RLDP.
1. Summary
We welcome that the Vale of Glamorgan Council has declared a ‘nature emergency’ and in 2021 committed to a target of no net loss of biodiversity in the Vale of Glamorgan. The deposit plan takes this a step further through its vision, objectives and policies in seeking
the achievement of net biodiversity benefit. We also welcome the recognition within the deposit plan and supporting documents that additional growth within the Vale has the potential to lead to negative effects on nationally and locally designated biodiversity. We
appreciate that the deposit plan’s policies seek to mitigate against these potential adverse effects with detailed wording and requirements.
However, we consider that the deposit plan would benefit from more specific mention of designated conservation sites especially where these are related to specific allocations and their associated policies. We note this issue was raised within the Integrated Sustainability Assessment (ISA) (see Section 2 below) however we do not see this recommendation properly reflected within the deposit plan itself. We consider this is a gap that should be addressed to ensure clarity within the policy requirements for any future planning applications.
General Approach to Designated Sites
In line with our role in development planning and our consultation remit, we advise that where new development may occur within or be likely to affect statutory designated sites including Special Areas of Conservation (SAC), Special Protection Areas (SPA), Sites of Special Scientific Interest (SSSI), National Nature Reserves (NNR) and Marine Conservation Zones (MCZ) this could be more clearly identified as a key consideration especially with respect to site allocations (housing and employment). We consider that the issue of avoiding or mitigating potential impacts and utilising opportunities for supporting and enhancing these sites (as noted by para 6.401 of the deposit plan) could have more substantial recognition across the deposit plan and its supporting documents. This would improve the clarity of approach.
We have furthermore noted that Policy SP20 (Biodiversity and Ecosystem Resilience) currently excludes specific mention of designated sites (although it does refer to protected species and habitats) and we suggest that this is addressed – our comments on SP20 are set out in Section 3 of this letter.
By across the plan, we mean there is scope to include mention of relevant statutorily designated sites within the constraints text for the sites listed in Appendix B of document BP44 Infrastructure Delivery Plan (perhaps summarising in line with the approach taken to the Historic Environment Record) and within document BP32A Green Infrastructure Assessment of Key Sites, evidence which can then be reflected as appropriate in Key Sites Policies (HG1 KS1 to KS5) to inform their master planning. The Preliminary Ecological Appraisals already undertaken for Key Sites (Key Site Supporting Information) would appear to hold relevant information in this respect.
We note that document BP32A has a useful general paragraph on biodiversity assets at paras 3.7-3.8 linked to the evidence collated in the Green Infrastructure Assessment (GIA). In short, where designated sites are identified in proximity to allocated sites it would be
helpful to make clear reference to them in a consistent manner. This would bring the deposit plan more fully into alignment with the ISA findings. For any employment sites
within proximity of designated sites, we consider that the employment background paper BP12A could potentially be updated to similar effect.
With reference to omissions on this matter, we refer you to our comments on sites set out in Section 4 of this letter, including sites KS1, HG1 (1), SP14 1. and SP14 4.
Overall, we consider that the recognition of designated sites appears somewhat inconsistent in the deposit plan, although we recognise that much of this is done by the
Green Infrastructure Strategy (GIS) which incorporates the GIA.
It may be that Policy SP20 (please see our suggested amendments in Section 3 of this letter) together with addressing the meaning of “areas of high ecological value” will also go some way towards resolving the points we raise.
Master Planning
We welcome the illustrative master plans included in the deposit plan but would caveat that at the detailed stages schemes must be able to adapt, where necessary, to site
specific environmental constraints (including protected sites, species and habitats), for example in response to updated ecological appraisals or detailed species surveys.
Designs need to be flexible enough to ensure compliance with the stepwise approach (avoid, minimise, mitigate) in achieving Net Biodiversity Benefit (NBB) and improving the resilience of ecosystems as required by Planning Policy Wales, edition 12 (PPW12) and Policy 9 of Future Wales, the National Plan. We note the plan has good reference to this within Policy SP20 and supporting paragraph 6.405, thus enabling thorough consideration
at the project/planning application level and in master planning.
Please see our detailed site-specific comments in Section 4 in order to consider where our comments may lead to adjustments in master plans. For example, the species protection issues we highlight with regard to KS3 at Readers Way, Rhoose.
Strategic Opportunity at Bro Tathan
In addition to the above points, we advise that the Bro Tathan area of the Vale includes a number of different allocations and is already known as an important ecological area for great crested newts (GCN) and dormice, in particular. Given the commitments already
made under previous planning applications at the site and the necessary requirement for future biodiversity provisions, we advise a more strategic overview of the area should be considered and either set out within the deposit plan or secured within an updated GIS.
This will ensure that development in the area:
• does not cause detriment to the maintenance of the favourable conservation status of protected species;
• results in green spaces and infrastructure that is meaningfully spatially connected and sufficient in size.
Overall, we consider piecemeal development of the St Athan area will not lead to effective conservation delivery and will make the planning process less efficient at project level.
Areas of High Ecological Value
As previously noted within our preferred strategy response (Ref: CAS-244275-Q4F4, dated: 14th February 2024), the deposit plan continues to make reference to avoiding
areas of ‘High Ecological Value’ (criterion 1 of SP20). We have not been able to establish where these areas are or how their ecological value is being determined. We consider this issue needs to be clarified and ideally a definition provided.
2. Integrated Sustainability Assessment (ISA)
With regards to Section 9.9 of the ISA, we agree that additional growth in the Vale has the potential to lead to negative effects on nationally and locally designated biodiversity. The ISA concludes that the housing-specific policies set out within the deposit plan work well to
mitigate the potential adverse effects, through design stipulations and policy inclusions.
The ISA then goes on to recommend that Key Site policies are updated, where appropriate, to reference specific designated sites which they are in proximity to, in
order to help establish appropriate protection and/or enhancement measures.
We agree with these recommendations and would go further in advising that all allocations and their associated policies should reference specific designated sites relevant to that site. For instance, we would advise Barry Woodlands SSSI and Walters Farm SSSI is identified in relation to Key Site 1 – Land at North West of Barry, and Barry Woodlands SSSI should also be identified for Housing Allocation HG1 (1) Land to the West of
Pencoedtre Lane. Please refer to our site-specific comments in Section 4 below.

3. Plan and Policy Wording
Strategic Policies
Strategic Policy SP19 – Green Infrastructure
We welcome that the GIS and GIA has informed the master planning of the Key Site allocations (6.395). To ensure this approach is carried forward for other development proposals, we consider there should be a stronger “policy hook” within Policy SP19 to link the content and evidence of the GI work to the policy and its influence on decision-making. Without this we consider there may be a risk of a policy gap/mismatch when determining planning applications.
This could be resolved by a new criterion such as:
“the provision of green infrastructure must have regard to any adopted or emerging guidance including the Green Infrastructure Strategy/Green Infrastructure Assessment
(and the Assets listed therein), and Green Infrastructure (Action) Plan for the Vale.”
To strengthen Policy SP19 we also recommend an addition to the wording of criterion 2 to read:
“Protect and enhance connectivity between existing green infrastructure assets and be planned wherever possible to positively support areas of high ecological value”.
We furthermore note that criterion 3 of SP19 refers to achieving net benefit for biodiversity whilst the policy overall seeks to provide, protect and enhance high quality multi-functional green infrastructure. We have previously commented that multi-functional green spaces may not always be compatible with biodiversity. It should be recognised that multifunctional uses of space can be to the detriment of the natural environment and so must be carefully considered. We recommend that paragraph 6.397 wording is updated to reflect this potential conflict so that NBB required by PPW (and as promoted by para 6.396 together with Policy SP20) is able to be prioritised and not compromised.
This point could also be raised under Policy SP4 Placemaking – at para 6.32. It should not be assumed that multifunctional spaces will also be delivering for nature in every situation and in some cases separate provision of spaces to meet biodiversity goals will be essential.
Paragraph 6.401 is welcomed regarding the opportunities that exist for the protection, maintenance and further enhancement of green infrastructure assets.
Strategic Policy 20 (SP20) – Biodiversity and Ecosystem Resilience
We welcome the inclusion of SP20 which recognises the importance of natural assets and aims to protect these. We have made comments regarding the term “high ecological value” in our Summary section at the start of this letter.
We also note that whilst reference is made to sites and areas of European, national and local importance (para. 6.402), this is not distinctly carried through within SP20 or within a specific detailed policy in the deposit plan. We advise that a more detailed policy for the Natural Environment (similar to DNP4 for the Historic Environment) could be included within the deposit plan and this should include reference to the protection of statutorily designated sites. Alternatively, SP20 itself could be updated to include reference to these in a similar manner to the approach taken to non-statutory designated sites provided by criterion 5 of SP20. We consider this would strengthen the deposit plan’s alignment to
section 6.4.3 of PPW12. This issue is also reflected in our feedback to the ISA as set out in Section 2.
By adding a detailed policy for the wider protection of the natural environment, there is scope to ensure a clearer message within the deposit plan regarding the need for natural resources (including land, air, water and soils) in the Vale to be protected for themselves and the essential ecosystem services they deliver. This is opposed to merely preventing pollution (deposit plan Policy DNP5). Taking such an approach would enable an
opportunity to add the consideration of Sustainable Management of Natural Resources (SMNR) into the plan policy framework rather than confining this to the deposit plan context (para 2.11) and the policy context of the GIS (page 53).
We note that Policy CC4: Renewable, Low and Zero Carbon Energy Generation is more distinct in seeking to safeguard a range of assets (including nature conservation interests and soil conservation interests) and we consider a similar policy approach may be useful
for all development proposals. We also suggest that the placemaking strategic policy (Policy SP4) could be altered in order to highlight the Natural Environment alongside its
current reference to the Historic Environment. We note that placemaking principles (Figure 11 - Identity) includes the need for development to respond to natural physical attributes of the site. This is an issue is linked to our site-specific comments (Section 4 below) where we cite, for example, the need to buffer woodlands, hedgerows and watercourses and preserve linear corridors.
Ensuring an SMNR approach will impact positively on the ground to safeguard and improve ecological networks and protect and enhance ecosystems, essential to meeting
the nature emergency. Topics we draw your attention to include river restoration where, in particular, the removal/remediation of physical modifications can make a significant impact upon water quality. The GIS provides scope to capture various projects and wider initiatives, including those based on catchment scale improvements and we welcome the opportunity to be continually involved in this work. We note and welcome the recognition of
nature-based solutions within Policies SP16, SP19 and SP20 and in detailed Policy CC6.
With regards to natural assets and water resources, we consider that specific reference to water quality is lacking within the strategic and/or detailed policies. Whilst we note that water quality is mentioned within criterion 9 of Policy SP16, we consider the deposit plan should include more direct reference to the Water Framework Directive. We consider there is an opportunity for SP20 to be updated to ensure developments protect water quality and quantity. Alternatively, as mentioned above, this could fit within a detailed policy for the protection of the natural environment.
As a minor point, please note that the South Central Area Statement is not hyphenated (para 2.10 and 2.11). Please note also that, referring to paragraph 6.404 and 6.405, the
requirements for developments to demonstrate NBB is based on PPW12, rather than The Environment (Wales) Act 2016.

Detailed Policies

Infrastructure
Whilst we note that the infrastructure requirements (such as sewerage capacity) have been investigated for certain key sites within the deposit plan, we consider there could be scope for a detailed policy to cover infrastructure requirements for all development.

Policy DNP7
We welcome Policy DNP7 of the deposit plan, which recognises the importance of preserving the natural darkness of the night sky and minimising light pollution, which we consider to be important in limiting adverse impacts upon local biodiversity and ecological
connectivity.

Policy DPN8
Please refer to comments made with regards to this policy under Section 6: Habitats Regulation Assessment (HRA).

Policy HG5 - Affordable Housing Exception Sites
We advise that, particularly given these sites are permissible outside of settlements and could be in countryside locations, criterion 6 should be amended to:
“There is no loss of land with significant recreational, amenity, agricultural, ecological or natural heritage value”.

EMP1 – Employment Regeneration Opportunity Areas
We note that the Former Aberthaw Power Station has been identified as an employment regeneration opportunity area. There are otter and water vole records on the site and we are aware of GCN records within the local area. We would advise against the inclusion of
the Aberthaw Nature Reserve within the allocation and advise that any application on the site would need to be supported by up-to-date ecological survey information and
appropriate conservation measures. Given the nature of the site, future applications will also need to be supported by appropriate land contamination investigations.

CC3 – Renewable Energy Local Search Areas
This policy identifies several sites where the potential for wind and solar development are the greatest (known as ‘search areas’). There are significant search areas located between Llantrithyd and St Hilary; no ecological information has been provided for these search areas, however given the records for GCN, water vole and otter local to these areas, it is likely that provision in the form of suitable habitats will need to be made for these species.
This could be substantial in scale, however without further ecological information we cannot advise further at this time. Notwithstanding, given the scale of the search area in this location and the likely ecological impacts, we advise that this area would benefit from spatial planning of biodiversity provision, at a greater than individual site scale.

Paragraph 2.81 – The Vale Nature Recovery Action Plan
We note reference to ‘6 broad habitat types’ including Woodland, Freshwater, Grassland, Coastal, Agriculture and Urban. We suggest this is amended to ‘6 broad ecosystems’ to reflect correct terminology and the State of Natural Resources Report 2025.

4. Strategic Sites
Overview
We previously provided detailed comments on the RLDP’s Strategic Sites, as set out in our response ref: CAS-234819-C1V3, dated 4th October 2023, which we refer you to. We welcome the additional information provided and note the inclusion of Green Infrastructure
Strategies for each of the Key Sites. However, we note that these do not include reference to protected species specifically and as a result we are unable to confirm that the provision for each site is appropriate. We observe that the road infrastructure for many of these sites severs woodlands and other substantial linear corridors. We advise that such sites are designed to minimise fragmentation in the landscape and advise that the road layouts and consequent severance is re-visited.

KS4 and KS5 are located within the vicinity of St Athan. This area is important for (and we are aware of) multiple records of GCN and dormice. Some of the area is already secured as compensation for impacts on these species associated with previous developments. We advise that the wider St Athan area is subject to spatial planning of biodiversity provision at a greater than individual site scale (as we have referenced in the Section 1 of this letter), in order to determine that:
• It does not cause detriment to the maintenance of the favourable conservation status of both GCN and dormice (strategic conservation plans should be established for both species);
• To ensure that green spaces and infrastructure are meaningfully spatially connected and sufficient in size;
We consider piecemeal development of these areas will not lead to effective conservation delivery and will cause the delivery of these sites to be less effective during the planning process.

Spatial Planning of Biodiversity
A masterplan or spatial biodiversity or GI plan should demonstrate the retention, provision and enhancement of essential areas for protected species. It should ensure that individual site-based habitat provisions are not designed in isolation but considered in association with nearby sites to demonstrate how habitat connectivity and resilience will be provided both across the site and to the wider landscape. Note that functional separation of public
open space and areas for biodiversity compensation may be required. Suitable buffers will need to be applied to any woodland and retained or created habitats on site. A sensitive lighting strategy will also likely be required for these sites. This point was raised previously during our review of the strategic candidate sites (ref: CAS-234819-C1V3, dated 4th October 2023).

Updated Surveys and Appropriate Buffer Zones
Further to the above comments, we welcome reference within the Infrastructure Delivery Plan for the requirement for updated ecological surveys and appropriate buffer zones to watercourses and retained habitat features for KS1 and KS2. Given the various ecological
constraints for each key site, we consider this advice should be included for each of the key sites.

Site Specific Comments
KS1 – Land at North West Barry
Protected Species – Dormice and bats are present on site. We advise that the masterplan is informed by surveys to ensure that biodiversity interests are maintained and enhanced. The site may require some areas to be retained an/or provision for habitats to support them. Dark areas and/or bespoke lighting scheme may also be required at project stage.
Protected Sites – The site is located in close proximity to Walters Farm and Barry Woodlands SSSI. As raised in our previous responses (CAS-234819-C1V3, dated: 4th
October 2023 and CAS-276923-N7H6, dated 17th April 2025), we have some concerns with the potential for increased and inappropriate use of the protected sites through recreational activities. We welcome that requirements have been detailed within HG1 KS1
under Green Infrastructure, Recreation Spaces and Biodiversity, which includes reference to emerging guidance for Suitable Alternate Natural Greenspace (SANG).

KS2 – North of Dinas Powys, off Cardiff Road
Protected Species – We note the supporting Preliminary Ecological Appraisal (PEA) (13th September 2022) which identifies potential for this site to support GCN, dormouse and bats. In the absence of species specific surveys, we are unable to advise whether the housing number aspirations for the site are realistic. We advise the scheme is designed to minimise severance of ecological corridors.

KS3 – Land at Readers Way
Protected Species – GCN are known to be present on this site (Readers Way Pond). The current masterplan indicates that the pond will be surrounded by built development and therefore built upon much of the terrestrial habitat which supports this pond. It is essential
that the masterplan provides a wide corridor from this pond to the wider countryside, other than via the closely managed grassland at Cardiff Airport. Any masterplan should make provision for this and any loss of habitat should be compensated for.

KS4 – Land at Church Farm
Protected Species - There are records of dormouse and GCN in the wider area. However, the supporting PEA indicates no direct impacts on the latter of the species. There appears to be extensive green space proposed in the illustrative masterplan, which we support.

KS5 – Land to the West of St Athan
Protected Species - The St Athan area is important area for GCN and dormouse. We would generally concur with the lower risk assessed for these species in association with this site. However, this is a substantial site and this and other sites in the St Athan area would benefit from spatial planning of biodiversity provision at a greater scale as reaffirmed elsewhere in this response.

5. Housing And Employment Allocations
Housing Allocations

HG1 (1) Land to the West of Pencoedtre Lane
Protected Sites: The site is within close proximity (200m) to Barry Woodlands Site of Special Scientific Interest (SSSI) and there is a risk from increased recreational use as a result of residential development, which could lead to impacts on the SSSI. Green space design must consider any emerging guidance for SANG to reduce recreational pressure on adjacent sites of biodiversity importance.
HG1 (2) Land at the Mole
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary European Marine Site (EMS). A HRA at project level will therefore be required.

HG1 (3) Land at Hayes Lane
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

HG1 (4) Land at Neptune Road
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

HG1 (5) Land between the Northern Access Road and Eglwys Brewis Road (Site C - Central Parcel)
Flood Risk: The site is located partially within Flood Zone 2 and 3 for Rivers, with the southern area of the site located within Flood Zone 3. We refer you to Sections 10.20 and 10.21 of TAN 15, which state that highly vulnerable development in Zone 3 should be avoided. Notwithstanding, we acknowledge that at masterplanning stage, there is scope to locate residential development away from areas of flood risk. We also welcome that
Appendix B of your Infrastructure Delivery Plan notes the requirement for an FCA at project level for this site.
Watercourse: Boverton Brook (Main River) runs through the site and any development will need to ensure no adverse impacts to the watercourse with appropriate buffers and design considerations.

HG1 (6) Land adjoining St Athan Road
Land Contamination: The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.

Rural Affordable Housing Led Sites
HG4 (1) Land to the East of Colwinston
Land Contamination: The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.

Major Employment Allocations
SP14 (1) Land east of Cardiff Airport, Rhoose
Protected Species and Protected Sites: The site is within close proximity (360m) of Barry Woodlands SSSI and there also appears to be significant potential for the site to support dormouse, GCN, otter and water vole. There are large areas of semi-natural habitats associated with this site including woodland, mature hedgerow and watercourses. These should be retained and significantly buffered from development. Connectivity between the
site and the wider environment should also be maintained. It is therefore currently not possible to advise whether the full aspirations of the site could be fulfilled.
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (2) Land south of Port Road (Model Farm), Rhoose
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (3) Bro Tathan Aerospace and Business Park
Protected Species: The site is located within an important area for GCN and dormice. As mentioned, this area would benefit from spatial planning of biodiversity provision at a
greater scale to better inform allocation.
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (4) Land to the South of Junction 34 of the M4, Hensol
Protected Sites: The site is located directly adjacent to Ely Valley SSSI. Given the biodiversity interest at the site, previous applications at the site include planning
commitments to conserve and enhance grasslands habitats on the site. These commitments have not yet materialised and the requirement for these provisions should be noted within the LDP.
Flood Risk: The site is located partially within Flood Zone 3 for Sea. We advise that an FCA will be required at project level to determine any flood risk implications at the site.

Local Employment Allocations
SP14 (5) Atlantic Trading Estate, Barry
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination. The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

SP14 (6) Windmill Park, Hayes Road, Barry
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination. The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.
Flood Risk: The site is located partially within Flood Zone 3 for Sea. We advise that an FCA will be required at project level to determine any flood risk implications at the site.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

SP14 (7) Vale Business Park, Llandow
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (8) Land at Llandow Trading Estate
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

6. Habitats Regulations Assessment (HRA)
Marine and Coastal Physical Processes
Coastal Squeeze
We note that coastal squeeze has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is that it “is unlikely that the Vale of Glamorgan RLDP will allocate many developments on
greenfield sites adjoining the estuary”.
We also note that Policy CC6 specifically relates to Coastal Defences and Shoreline Management, with reference to the Shoreline Management Plans. We recommend the use of NRW’s Assessment of Coastal Squeeze at the project level for anyone proposing to
undertake works to coastal structures.

Loss of Functionally Linked Habitat
As part of the Preferred Strategy consultation, we advised that consideration was given to potential impacts on migratory fish features of the Severn Estuary EMS. In particular, we referenced the River Ely and its tributaries providing supporting habitat for essential life cycle processes of some or all the diadromous fish species.
Within the deposit plan HRA, it is noted that likely significant effects to the migratory fish features of the Severn Estuary EMS has been ruled out, as none of the sites allocated in the RLDP lie in close proximity to the River Ely and connected watercourses. We therefore
agree with this conclusion.
In relation to bird features, Table 8 of the Appropriate Assessment identifies many key sites and allocations with high to medium potential for functional linkage to the Severn Estuary EMS. We note that loss of functionally linked habitat has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is the inclusion of ‘Policy DNP8 – Severn Estuary Recreational
Pressure’ within the deposit plan.

Policy DNP8
We advise that clarification is needed in relation to this policy, as while we welcome the supporting text regarding functionally linked land outlined in paragraph 6.76 of the HRA, the policy is mainly focused on recreational pressure and is titled as such. We also note a discrepancy between the policy wording in paragraph 6.76 and Policy DNP8 in the deposit plan itself.

Visual and Noise Disturbance (During Construction)
Within the deposit plan HRA, visual and noise disturbance has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is through the inclusion of recommendations outlined in 6.83 of the HRA to the supporting text of Policy SP20, which we welcome.
We also welcome the recommendation in relation to potential functionally linked land as outlined in paragraph 6.84 of the HRA.

Recreational Pressure
Within the deposit plan HRA, recreational pressure has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. Again, the justification for this is the inclusion of ‘Policy DNP8 – Severn Estuary Recreational Pressure’ within the deposit plan, which as above, we advise needs
clarification.
We note that no visitor data has been collected from access points within the Vale of Glamorgan, but we welcome reference to the visitor surveys undertaken by
Monmouthshire and Torfaen, as well as the 2022 visitor survey commissioned by Stroud District Council.
We note that paragraph 6.25 of the HRA states that “three Key Sites and several other housing allocations lie within the 12.6km core recreational catchment that has been
deemed most appropriate for the Severn Estuary SAC/SPA/Ramsar”. However, we also note that Table 6 in the HRA only includes two Key Sites requiring mitigation, with KS3 being omitted. We advise that clarification is needed at the project level as to whether developments are situated within the 12.6km catchment area.

7. Strategic Flood Consequence Assessment (SFCA)
We have reviewed the submitted SFCA and agree with the scope of the assessment made.
We note there is currently an upper catchment Natural Flood Management (NFM) / Nature Based Solutions (NbS) project on the Cadoxton to reduce flood risk to Dinas Powys, Any updated SCFA should have regard to NFM schemes being progressed in their area and
proposals should be clearly outlined in the Development Plan (in accordance with TAN 15 2025).

8. Green Infrastructure Strategy (GIS)
We understand that the published GIS has not been updated to reflect the latest stage of the deposit plan and refers only to the preferred strategy stage (para 2.2.3). We previously provided advice on the Green Infrastructure Assessment (GIA) (re: CAS-252087-F0H1, dated 14th May 2024) which is included within the GIS. We refer you to these comments, noting that the GIS will be kept under continual review (para 1.2.5).

Thank you for consulting Natural Resources Wales (NRW) on the Vale of Glamorgan Replacement Local Development Plan (RLDP) Deposit Plan, which we received on 28 January 2026.
We have reviewed the deposit plan and published documents and have recommendations on matters relating to coherence and consistency. We advise these are addressed prior to submission of the RLDP.
1. Summary
We welcome that the Vale of Glamorgan Council has declared a ‘nature emergency’ and in 2021 committed to a target of no net loss of biodiversity in the Vale of Glamorgan. The deposit plan takes this a step further through its vision, objectives and policies in seeking
the achievement of net biodiversity benefit. We also welcome the recognition within the deposit plan and supporting documents that additional growth within the Vale has the potential to lead to negative effects on nationally and locally designated biodiversity. We
appreciate that the deposit plan’s policies seek to mitigate against these potential adverse effects with detailed wording and requirements.
However, we consider that the deposit plan would benefit from more specific mention of designated conservation sites especially where these are related to specific allocations and their associated policies. We note this issue was raised within the Integrated Sustainability Assessment (ISA) (see Section 2 below) however we do not see this recommendation properly reflected within the deposit plan itself. We consider this is a gap that should be addressed to ensure clarity within the policy requirements for any future planning applications.
General Approach to Designated Sites
In line with our role in development planning and our consultation remit, we advise that where new development may occur within or be likely to affect statutory designated sites including Special Areas of Conservation (SAC), Special Protection Areas (SPA), Sites of Special Scientific Interest (SSSI), National Nature Reserves (NNR) and Marine Conservation Zones (MCZ) this could be more clearly identified as a key consideration especially with respect to site allocations (housing and employment). We consider that the issue of avoiding or mitigating potential impacts and utilising opportunities for supporting and enhancing these sites (as noted by para 6.401 of the deposit plan) could have more substantial recognition across the deposit plan and its supporting documents. This would improve the clarity of approach.
We have furthermore noted that Policy SP20 (Biodiversity and Ecosystem Resilience) currently excludes specific mention of designated sites (although it does refer to protected species and habitats) and we suggest that this is addressed – our comments on SP20 are set out in Section 3 of this letter.
By across the plan, we mean there is scope to include mention of relevant statutorily designated sites within the constraints text for the sites listed in Appendix B of document BP44 Infrastructure Delivery Plan (perhaps summarising in line with the approach taken to the Historic Environment Record) and within document BP32A Green Infrastructure Assessment of Key Sites, evidence which can then be reflected as appropriate in Key Sites Policies (HG1 KS1 to KS5) to inform their master planning. The Preliminary Ecological Appraisals already undertaken for Key Sites (Key Site Supporting Information) would appear to hold relevant information in this respect.
We note that document BP32A has a useful general paragraph on biodiversity assets at paras 3.7-3.8 linked to the evidence collated in the Green Infrastructure Assessment (GIA). In short, where designated sites are identified in proximity to allocated sites it would be
helpful to make clear reference to them in a consistent manner. This would bring the deposit plan more fully into alignment with the ISA findings. For any employment sites
within proximity of designated sites, we consider that the employment background paper BP12A could potentially be updated to similar effect.
With reference to omissions on this matter, we refer you to our comments on sites set out in Section 4 of this letter, including sites KS1, HG1 (1), SP14 1. and SP14 4.
Overall, we consider that the recognition of designated sites appears somewhat inconsistent in the deposit plan, although we recognise that much of this is done by the
Green Infrastructure Strategy (GIS) which incorporates the GIA.
It may be that Policy SP20 (please see our suggested amendments in Section 3 of this letter) together with addressing the meaning of “areas of high ecological value” will also go some way towards resolving the points we raise.
Master Planning
We welcome the illustrative master plans included in the deposit plan but would caveat that at the detailed stages schemes must be able to adapt, where necessary, to site
specific environmental constraints (including protected sites, species and habitats), for example in response to updated ecological appraisals or detailed species surveys.
Designs need to be flexible enough to ensure compliance with the stepwise approach (avoid, minimise, mitigate) in achieving Net Biodiversity Benefit (NBB) and improving the resilience of ecosystems as required by Planning Policy Wales, edition 12 (PPW12) and Policy 9 of Future Wales, the National Plan. We note the plan has good reference to this within Policy SP20 and supporting paragraph 6.405, thus enabling thorough consideration
at the project/planning application level and in master planning.
Please see our detailed site-specific comments in Section 4 in order to consider where our comments may lead to adjustments in master plans. For example, the species protection issues we highlight with regard to KS3 at Readers Way, Rhoose.
Strategic Opportunity at Bro Tathan
In addition to the above points, we advise that the Bro Tathan area of the Vale includes a number of different allocations and is already known as an important ecological area for great crested newts (GCN) and dormice, in particular. Given the commitments already
made under previous planning applications at the site and the necessary requirement for future biodiversity provisions, we advise a more strategic overview of the area should be considered and either set out within the deposit plan or secured within an updated GIS.
This will ensure that development in the area:
• does not cause detriment to the maintenance of the favourable conservation status of protected species;
• results in green spaces and infrastructure that is meaningfully spatially connected and sufficient in size.
Overall, we consider piecemeal development of the St Athan area will not lead to effective conservation delivery and will make the planning process less efficient at project level.
Areas of High Ecological Value
As previously noted within our preferred strategy response (Ref: CAS-244275-Q4F4, dated: 14th February 2024), the deposit plan continues to make reference to avoiding
areas of ‘High Ecological Value’ (criterion 1 of SP20). We have not been able to establish where these areas are or how their ecological value is being determined. We consider this issue needs to be clarified and ideally a definition provided.
2. Integrated Sustainability Assessment (ISA)
With regards to Section 9.9 of the ISA, we agree that additional growth in the Vale has the potential to lead to negative effects on nationally and locally designated biodiversity. The ISA concludes that the housing-specific policies set out within the deposit plan work well to
mitigate the potential adverse effects, through design stipulations and policy inclusions.
The ISA then goes on to recommend that Key Site policies are updated, where appropriate, to reference specific designated sites which they are in proximity to, in
order to help establish appropriate protection and/or enhancement measures.
We agree with these recommendations and would go further in advising that all allocations and their associated policies should reference specific designated sites relevant to that site. For instance, we would advise Barry Woodlands SSSI and Walters Farm SSSI is identified in relation to Key Site 1 – Land at North West of Barry, and Barry Woodlands SSSI should also be identified for Housing Allocation HG1 (1) Land to the West of
Pencoedtre Lane. Please refer to our site-specific comments in Section 4 below.

3. Plan and Policy Wording
Strategic Policies
Strategic Policy SP19 – Green Infrastructure
We welcome that the GIS and GIA has informed the master planning of the Key Site allocations (6.395). To ensure this approach is carried forward for other development proposals, we consider there should be a stronger “policy hook” within Policy SP19 to link the content and evidence of the GI work to the policy and its influence on decision-making. Without this we consider there may be a risk of a policy gap/mismatch when determining planning applications.
This could be resolved by a new criterion such as:
“the provision of green infrastructure must have regard to any adopted or emerging guidance including the Green Infrastructure Strategy/Green Infrastructure Assessment
(and the Assets listed therein), and Green Infrastructure (Action) Plan for the Vale.”
To strengthen Policy SP19 we also recommend an addition to the wording of criterion 2 to read:
“Protect and enhance connectivity between existing green infrastructure assets and be planned wherever possible to positively support areas of high ecological value”.
We furthermore note that criterion 3 of SP19 refers to achieving net benefit for biodiversity whilst the policy overall seeks to provide, protect and enhance high quality multi-functional green infrastructure. We have previously commented that multi-functional green spaces may not always be compatible with biodiversity. It should be recognised that multifunctional uses of space can be to the detriment of the natural environment and so must be carefully considered. We recommend that paragraph 6.397 wording is updated to reflect this potential conflict so that NBB required by PPW (and as promoted by para 6.396 together with Policy SP20) is able to be prioritised and not compromised.
This point could also be raised under Policy SP4 Placemaking – at para 6.32. It should not be assumed that multifunctional spaces will also be delivering for nature in every situation and in some cases separate provision of spaces to meet biodiversity goals will be essential.
Paragraph 6.401 is welcomed regarding the opportunities that exist for the protection, maintenance and further enhancement of green infrastructure assets.
Strategic Policy 20 (SP20) – Biodiversity and Ecosystem Resilience
We welcome the inclusion of SP20 which recognises the importance of natural assets and aims to protect these. We have made comments regarding the term “high ecological value” in our Summary section at the start of this letter.
We also note that whilst reference is made to sites and areas of European, national and local importance (para. 6.402), this is not distinctly carried through within SP20 or within a specific detailed policy in the deposit plan. We advise that a more detailed policy for the Natural Environment (similar to DNP4 for the Historic Environment) could be included within the deposit plan and this should include reference to the protection of statutorily designated sites. Alternatively, SP20 itself could be updated to include reference to these in a similar manner to the approach taken to non-statutory designated sites provided by criterion 5 of SP20. We consider this would strengthen the deposit plan’s alignment to
section 6.4.3 of PPW12. This issue is also reflected in our feedback to the ISA as set out in Section 2.
By adding a detailed policy for the wider protection of the natural environment, there is scope to ensure a clearer message within the deposit plan regarding the need for natural resources (including land, air, water and soils) in the Vale to be protected for themselves and the essential ecosystem services they deliver. This is opposed to merely preventing pollution (deposit plan Policy DNP5). Taking such an approach would enable an
opportunity to add the consideration of Sustainable Management of Natural Resources (SMNR) into the plan policy framework rather than confining this to the deposit plan context (para 2.11) and the policy context of the GIS (page 53).
We note that Policy CC4: Renewable, Low and Zero Carbon Energy Generation is more distinct in seeking to safeguard a range of assets (including nature conservation interests and soil conservation interests) and we consider a similar policy approach may be useful
for all development proposals. We also suggest that the placemaking strategic policy (Policy SP4) could be altered in order to highlight the Natural Environment alongside its
current reference to the Historic Environment. We note that placemaking principles (Figure 11 - Identity) includes the need for development to respond to natural physical attributes of the site. This is an issue is linked to our site-specific comments (Section 4 below) where we cite, for example, the need to buffer woodlands, hedgerows and watercourses and preserve linear corridors.
Ensuring an SMNR approach will impact positively on the ground to safeguard and improve ecological networks and protect and enhance ecosystems, essential to meeting
the nature emergency. Topics we draw your attention to include river restoration where, in particular, the removal/remediation of physical modifications can make a significant impact upon water quality. The GIS provides scope to capture various projects and wider initiatives, including those based on catchment scale improvements and we welcome the opportunity to be continually involved in this work. We note and welcome the recognition of
nature-based solutions within Policies SP16, SP19 and SP20 and in detailed Policy CC6.
With regards to natural assets and water resources, we consider that specific reference to water quality is lacking within the strategic and/or detailed policies. Whilst we note that water quality is mentioned within criterion 9 of Policy SP16, we consider the deposit plan should include more direct reference to the Water Framework Directive. We consider there is an opportunity for SP20 to be updated to ensure developments protect water quality and quantity. Alternatively, as mentioned above, this could fit within a detailed policy for the protection of the natural environment.
As a minor point, please note that the South Central Area Statement is not hyphenated (para 2.10 and 2.11). Please note also that, referring to paragraph 6.404 and 6.405, the
requirements for developments to demonstrate NBB is based on PPW12, rather than The Environment (Wales) Act 2016.

Detailed Policies

Infrastructure
Whilst we note that the infrastructure requirements (such as sewerage capacity) have been investigated for certain key sites within the deposit plan, we consider there could be scope for a detailed policy to cover infrastructure requirements for all development.

Policy DNP7
We welcome Policy DNP7 of the deposit plan, which recognises the importance of preserving the natural darkness of the night sky and minimising light pollution, which we consider to be important in limiting adverse impacts upon local biodiversity and ecological
connectivity.

Policy DPN8
Please refer to comments made with regards to this policy under Section 6: Habitats Regulation Assessment (HRA).

Policy HG5 - Affordable Housing Exception Sites
We advise that, particularly given these sites are permissible outside of settlements and could be in countryside locations, criterion 6 should be amended to:
“There is no loss of land with significant recreational, amenity, agricultural, ecological or natural heritage value”.

EMP1 – Employment Regeneration Opportunity Areas
We note that the Former Aberthaw Power Station has been identified as an employment regeneration opportunity area. There are otter and water vole records on the site and we are aware of GCN records within the local area. We would advise against the inclusion of
the Aberthaw Nature Reserve within the allocation and advise that any application on the site would need to be supported by up-to-date ecological survey information and
appropriate conservation measures. Given the nature of the site, future applications will also need to be supported by appropriate land contamination investigations.

CC3 – Renewable Energy Local Search Areas
This policy identifies several sites where the potential for wind and solar development are the greatest (known as ‘search areas’). There are significant search areas located between Llantrithyd and St Hilary; no ecological information has been provided for these search areas, however given the records for GCN, water vole and otter local to these areas, it is likely that provision in the form of suitable habitats will need to be made for these species.
This could be substantial in scale, however without further ecological information we cannot advise further at this time. Notwithstanding, given the scale of the search area in this location and the likely ecological impacts, we advise that this area would benefit from spatial planning of biodiversity provision, at a greater than individual site scale.

Paragraph 2.81 – The Vale Nature Recovery Action Plan
We note reference to ‘6 broad habitat types’ including Woodland, Freshwater, Grassland, Coastal, Agriculture and Urban. We suggest this is amended to ‘6 broad ecosystems’ to reflect correct terminology and the State of Natural Resources Report 2025.

4. Strategic Sites
Overview
We previously provided detailed comments on the RLDP’s Strategic Sites, as set out in our response ref: CAS-234819-C1V3, dated 4th October 2023, which we refer you to. We welcome the additional information provided and note the inclusion of Green Infrastructure
Strategies for each of the Key Sites. However, we note that these do not include reference to protected species specifically and as a result we are unable to confirm that the provision for each site is appropriate. We observe that the road infrastructure for many of these sites severs woodlands and other substantial linear corridors. We advise that such sites are designed to minimise fragmentation in the landscape and advise that the road layouts and consequent severance is re-visited.

KS4 and KS5 are located within the vicinity of St Athan. This area is important for (and we are aware of) multiple records of GCN and dormice. Some of the area is already secured as compensation for impacts on these species associated with previous developments. We advise that the wider St Athan area is subject to spatial planning of biodiversity provision at a greater than individual site scale (as we have referenced in the Section 1 of this letter), in order to determine that:
• It does not cause detriment to the maintenance of the favourable conservation status of both GCN and dormice (strategic conservation plans should be established for both species);
• To ensure that green spaces and infrastructure are meaningfully spatially connected and sufficient in size;
We consider piecemeal development of these areas will not lead to effective conservation delivery and will cause the delivery of these sites to be less effective during the planning process.

Spatial Planning of Biodiversity
A masterplan or spatial biodiversity or GI plan should demonstrate the retention, provision and enhancement of essential areas for protected species. It should ensure that individual site-based habitat provisions are not designed in isolation but considered in association with nearby sites to demonstrate how habitat connectivity and resilience will be provided both across the site and to the wider landscape. Note that functional separation of public
open space and areas for biodiversity compensation may be required. Suitable buffers will need to be applied to any woodland and retained or created habitats on site. A sensitive lighting strategy will also likely be required for these sites. This point was raised previously during our review of the strategic candidate sites (ref: CAS-234819-C1V3, dated 4th October 2023).

Updated Surveys and Appropriate Buffer Zones
Further to the above comments, we welcome reference within the Infrastructure Delivery Plan for the requirement for updated ecological surveys and appropriate buffer zones to watercourses and retained habitat features for KS1 and KS2. Given the various ecological
constraints for each key site, we consider this advice should be included for each of the key sites.

Site Specific Comments
KS1 – Land at North West Barry
Protected Species – Dormice and bats are present on site. We advise that the masterplan is informed by surveys to ensure that biodiversity interests are maintained and enhanced. The site may require some areas to be retained an/or provision for habitats to support them. Dark areas and/or bespoke lighting scheme may also be required at project stage.
Protected Sites – The site is located in close proximity to Walters Farm and Barry Woodlands SSSI. As raised in our previous responses (CAS-234819-C1V3, dated: 4th
October 2023 and CAS-276923-N7H6, dated 17th April 2025), we have some concerns with the potential for increased and inappropriate use of the protected sites through recreational activities. We welcome that requirements have been detailed within HG1 KS1
under Green Infrastructure, Recreation Spaces and Biodiversity, which includes reference to emerging guidance for Suitable Alternate Natural Greenspace (SANG).

KS2 – North of Dinas Powys, off Cardiff Road
Protected Species – We note the supporting Preliminary Ecological Appraisal (PEA) (13th September 2022) which identifies potential for this site to support GCN, dormouse and bats. In the absence of species specific surveys, we are unable to advise whether the housing number aspirations for the site are realistic. We advise the scheme is designed to minimise severance of ecological corridors.

KS3 – Land at Readers Way
Protected Species – GCN are known to be present on this site (Readers Way Pond). The current masterplan indicates that the pond will be surrounded by built development and therefore built upon much of the terrestrial habitat which supports this pond. It is essential
that the masterplan provides a wide corridor from this pond to the wider countryside, other than via the closely managed grassland at Cardiff Airport. Any masterplan should make provision for this and any loss of habitat should be compensated for.

KS4 – Land at Church Farm
Protected Species - There are records of dormouse and GCN in the wider area. However, the supporting PEA indicates no direct impacts on the latter of the species. There appears to be extensive green space proposed in the illustrative masterplan, which we support.

KS5 – Land to the West of St Athan
Protected Species - The St Athan area is important area for GCN and dormouse. We would generally concur with the lower risk assessed for these species in association with this site. However, this is a substantial site and this and other sites in the St Athan area would benefit from spatial planning of biodiversity provision at a greater scale as reaffirmed elsewhere in this response.

5. Housing And Employment Allocations
Housing Allocations

HG1 (1) Land to the West of Pencoedtre Lane
Protected Sites: The site is within close proximity (200m) to Barry Woodlands Site of Special Scientific Interest (SSSI) and there is a risk from increased recreational use as a result of residential development, which could lead to impacts on the SSSI. Green space design must consider any emerging guidance for SANG to reduce recreational pressure on adjacent sites of biodiversity importance.
HG1 (2) Land at the Mole
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary European Marine Site (EMS). A HRA at project level will therefore be required.

HG1 (3) Land at Hayes Lane
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

HG1 (4) Land at Neptune Road
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

HG1 (5) Land between the Northern Access Road and Eglwys Brewis Road (Site C - Central Parcel)
Flood Risk: The site is located partially within Flood Zone 2 and 3 for Rivers, with the southern area of the site located within Flood Zone 3. We refer you to Sections 10.20 and 10.21 of TAN 15, which state that highly vulnerable development in Zone 3 should be avoided. Notwithstanding, we acknowledge that at masterplanning stage, there is scope to locate residential development away from areas of flood risk. We also welcome that
Appendix B of your Infrastructure Delivery Plan notes the requirement for an FCA at project level for this site.
Watercourse: Boverton Brook (Main River) runs through the site and any development will need to ensure no adverse impacts to the watercourse with appropriate buffers and design considerations.

HG1 (6) Land adjoining St Athan Road
Land Contamination: The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.

Rural Affordable Housing Led Sites
HG4 (1) Land to the East of Colwinston
Land Contamination: The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.

Major Employment Allocations
SP14 (1) Land east of Cardiff Airport, Rhoose
Protected Species and Protected Sites: The site is within close proximity (360m) of Barry Woodlands SSSI and there also appears to be significant potential for the site to support dormouse, GCN, otter and water vole. There are large areas of semi-natural habitats associated with this site including woodland, mature hedgerow and watercourses. These should be retained and significantly buffered from development. Connectivity between the
site and the wider environment should also be maintained. It is therefore currently not possible to advise whether the full aspirations of the site could be fulfilled.
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (2) Land south of Port Road (Model Farm), Rhoose
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (3) Bro Tathan Aerospace and Business Park
Protected Species: The site is located within an important area for GCN and dormice. As mentioned, this area would benefit from spatial planning of biodiversity provision at a
greater scale to better inform allocation.
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (4) Land to the South of Junction 34 of the M4, Hensol
Protected Sites: The site is located directly adjacent to Ely Valley SSSI. Given the biodiversity interest at the site, previous applications at the site include planning
commitments to conserve and enhance grasslands habitats on the site. These commitments have not yet materialised and the requirement for these provisions should be noted within the LDP.
Flood Risk: The site is located partially within Flood Zone 3 for Sea. We advise that an FCA will be required at project level to determine any flood risk implications at the site.

Local Employment Allocations
SP14 (5) Atlantic Trading Estate, Barry
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination. The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

SP14 (6) Windmill Park, Hayes Road, Barry
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination. The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.
Flood Risk: The site is located partially within Flood Zone 3 for Sea. We advise that an FCA will be required at project level to determine any flood risk implications at the site.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

SP14 (7) Vale Business Park, Llandow
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (8) Land at Llandow Trading Estate
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

6. Habitats Regulations Assessment (HRA)
Marine and Coastal Physical Processes
Coastal Squeeze
We note that coastal squeeze has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is that it “is unlikely that the Vale of Glamorgan RLDP will allocate many developments on
greenfield sites adjoining the estuary”.
We also note that Policy CC6 specifically relates to Coastal Defences and Shoreline Management, with reference to the Shoreline Management Plans. We recommend the use of NRW’s Assessment of Coastal Squeeze at the project level for anyone proposing to
undertake works to coastal structures.

Loss of Functionally Linked Habitat
As part of the Preferred Strategy consultation, we advised that consideration was given to potential impacts on migratory fish features of the Severn Estuary EMS. In particular, we referenced the River Ely and its tributaries providing supporting habitat for essential life cycle processes of some or all the diadromous fish species.
Within the deposit plan HRA, it is noted that likely significant effects to the migratory fish features of the Severn Estuary EMS has been ruled out, as none of the sites allocated in the RLDP lie in close proximity to the River Ely and connected watercourses. We therefore
agree with this conclusion.
In relation to bird features, Table 8 of the Appropriate Assessment identifies many key sites and allocations with high to medium potential for functional linkage to the Severn Estuary EMS. We note that loss of functionally linked habitat has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is the inclusion of ‘Policy DNP8 – Severn Estuary Recreational
Pressure’ within the deposit plan.

Policy DNP8
We advise that clarification is needed in relation to this policy, as while we welcome the supporting text regarding functionally linked land outlined in paragraph 6.76 of the HRA, the policy is mainly focused on recreational pressure and is titled as such. We also note a discrepancy between the policy wording in paragraph 6.76 and Policy DNP8 in the deposit plan itself.

Visual and Noise Disturbance (During Construction)
Within the deposit plan HRA, visual and noise disturbance has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is through the inclusion of recommendations outlined in 6.83 of the HRA to the supporting text of Policy SP20, which we welcome.
We also welcome the recommendation in relation to potential functionally linked land as outlined in paragraph 6.84 of the HRA.

Recreational Pressure
Within the deposit plan HRA, recreational pressure has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. Again, the justification for this is the inclusion of ‘Policy DNP8 – Severn Estuary Recreational Pressure’ within the deposit plan, which as above, we advise needs
clarification.
We note that no visitor data has been collected from access points within the Vale of Glamorgan, but we welcome reference to the visitor surveys undertaken by
Monmouthshire and Torfaen, as well as the 2022 visitor survey commissioned by Stroud District Council.
We note that paragraph 6.25 of the HRA states that “three Key Sites and several other housing allocations lie within the 12.6km core recreational catchment that has been
deemed most appropriate for the Severn Estuary SAC/SPA/Ramsar”. However, we also note that Table 6 in the HRA only includes two Key Sites requiring mitigation, with KS3 being omitted. We advise that clarification is needed at the project level as to whether developments are situated within the 12.6km catchment area.

7. Strategic Flood Consequence Assessment (SFCA)
We have reviewed the submitted SFCA and agree with the scope of the assessment made.
We note there is currently an upper catchment Natural Flood Management (NFM) / Nature Based Solutions (NbS) project on the Cadoxton to reduce flood risk to Dinas Powys, Any updated SCFA should have regard to NFM schemes being progressed in their area and
proposals should be clearly outlined in the Development Plan (in accordance with TAN 15 2025).

8. Green Infrastructure Strategy (GIS)
We understand that the published GIS has not been updated to reflect the latest stage of the deposit plan and refers only to the preferred strategy stage (para 2.2.3). We previously provided advice on the Green Infrastructure Assessment (GIA) (re: CAS-252087-F0H1, dated 14th May 2024) which is included within the GIS. We refer you to these comments, noting that the GIS will be kept under continual review (para 1.2.5).

Thank you for consulting Natural Resources Wales (NRW) on the Vale of Glamorgan Replacement Local Development Plan (RLDP) Deposit Plan, which we received on 28 January 2026.
We have reviewed the deposit plan and published documents and have recommendations on matters relating to coherence and consistency. We advise these are addressed prior to submission of the RLDP.
1. Summary
We welcome that the Vale of Glamorgan Council has declared a ‘nature emergency’ and in 2021 committed to a target of no net loss of biodiversity in the Vale of Glamorgan. The deposit plan takes this a step further through its vision, objectives and policies in seeking
the achievement of net biodiversity benefit. We also welcome the recognition within the deposit plan and supporting documents that additional growth within the Vale has the potential to lead to negative effects on nationally and locally designated biodiversity. We
appreciate that the deposit plan’s policies seek to mitigate against these potential adverse effects with detailed wording and requirements.
However, we consider that the deposit plan would benefit from more specific mention of designated conservation sites especially where these are related to specific allocations and their associated policies. We note this issue was raised within the Integrated Sustainability Assessment (ISA) (see Section 2 below) however we do not see this recommendation properly reflected within the deposit plan itself. We consider this is a gap that should be addressed to ensure clarity within the policy requirements for any future planning applications.
General Approach to Designated Sites
In line with our role in development planning and our consultation remit, we advise that where new development may occur within or be likely to affect statutory designated sites including Special Areas of Conservation (SAC), Special Protection Areas (SPA), Sites of Special Scientific Interest (SSSI), National Nature Reserves (NNR) and Marine Conservation Zones (MCZ) this could be more clearly identified as a key consideration especially with respect to site allocations (housing and employment). We consider that the issue of avoiding or mitigating potential impacts and utilising opportunities for supporting and enhancing these sites (as noted by para 6.401 of the deposit plan) could have more substantial recognition across the deposit plan and its supporting documents. This would improve the clarity of approach.
We have furthermore noted that Policy SP20 (Biodiversity and Ecosystem Resilience) currently excludes specific mention of designated sites (although it does refer to protected species and habitats) and we suggest that this is addressed – our comments on SP20 are set out in Section 3 of this letter.
By across the plan, we mean there is scope to include mention of relevant statutorily designated sites within the constraints text for the sites listed in Appendix B of document BP44 Infrastructure Delivery Plan (perhaps summarising in line with the approach taken to the Historic Environment Record) and within document BP32A Green Infrastructure Assessment of Key Sites, evidence which can then be reflected as appropriate in Key Sites Policies (HG1 KS1 to KS5) to inform their master planning. The Preliminary Ecological Appraisals already undertaken for Key Sites (Key Site Supporting Information) would appear to hold relevant information in this respect.
We note that document BP32A has a useful general paragraph on biodiversity assets at paras 3.7-3.8 linked to the evidence collated in the Green Infrastructure Assessment (GIA). In short, where designated sites are identified in proximity to allocated sites it would be
helpful to make clear reference to them in a consistent manner. This would bring the deposit plan more fully into alignment with the ISA findings. For any employment sites
within proximity of designated sites, we consider that the employment background paper BP12A could potentially be updated to similar effect.
With reference to omissions on this matter, we refer you to our comments on sites set out in Section 4 of this letter, including sites KS1, HG1 (1), SP14 1. and SP14 4.
Overall, we consider that the recognition of designated sites appears somewhat inconsistent in the deposit plan, although we recognise that much of this is done by the
Green Infrastructure Strategy (GIS) which incorporates the GIA.
It may be that Policy SP20 (please see our suggested amendments in Section 3 of this letter) together with addressing the meaning of “areas of high ecological value” will also go some way towards resolving the points we raise.
Master Planning
We welcome the illustrative master plans included in the deposit plan but would caveat that at the detailed stages schemes must be able to adapt, where necessary, to site
specific environmental constraints (including protected sites, species and habitats), for example in response to updated ecological appraisals or detailed species surveys.
Designs need to be flexible enough to ensure compliance with the stepwise approach (avoid, minimise, mitigate) in achieving Net Biodiversity Benefit (NBB) and improving the resilience of ecosystems as required by Planning Policy Wales, edition 12 (PPW12) and Policy 9 of Future Wales, the National Plan. We note the plan has good reference to this within Policy SP20 and supporting paragraph 6.405, thus enabling thorough consideration
at the project/planning application level and in master planning.
Please see our detailed site-specific comments in Section 4 in order to consider where our comments may lead to adjustments in master plans. For example, the species protection issues we highlight with regard to KS3 at Readers Way, Rhoose.
Strategic Opportunity at Bro Tathan
In addition to the above points, we advise that the Bro Tathan area of the Vale includes a number of different allocations and is already known as an important ecological area for great crested newts (GCN) and dormice, in particular. Given the commitments already
made under previous planning applications at the site and the necessary requirement for future biodiversity provisions, we advise a more strategic overview of the area should be considered and either set out within the deposit plan or secured within an updated GIS.
This will ensure that development in the area:
• does not cause detriment to the maintenance of the favourable conservation status of protected species;
• results in green spaces and infrastructure that is meaningfully spatially connected and sufficient in size.
Overall, we consider piecemeal development of the St Athan area will not lead to effective conservation delivery and will make the planning process less efficient at project level.
Areas of High Ecological Value
As previously noted within our preferred strategy response (Ref: CAS-244275-Q4F4, dated: 14th February 2024), the deposit plan continues to make reference to avoiding
areas of ‘High Ecological Value’ (criterion 1 of SP20). We have not been able to establish where these areas are or how their ecological value is being determined. We consider this issue needs to be clarified and ideally a definition provided.
2. Integrated Sustainability Assessment (ISA)
With regards to Section 9.9 of the ISA, we agree that additional growth in the Vale has the potential to lead to negative effects on nationally and locally designated biodiversity. The ISA concludes that the housing-specific policies set out within the deposit plan work well to
mitigate the potential adverse effects, through design stipulations and policy inclusions.
The ISA then goes on to recommend that Key Site policies are updated, where appropriate, to reference specific designated sites which they are in proximity to, in
order to help establish appropriate protection and/or enhancement measures.
We agree with these recommendations and would go further in advising that all allocations and their associated policies should reference specific designated sites relevant to that site. For instance, we would advise Barry Woodlands SSSI and Walters Farm SSSI is identified in relation to Key Site 1 – Land at North West of Barry, and Barry Woodlands SSSI should also be identified for Housing Allocation HG1 (1) Land to the West of
Pencoedtre Lane. Please refer to our site-specific comments in Section 4 below.

3. Plan and Policy Wording
Strategic Policies
Strategic Policy SP19 – Green Infrastructure
We welcome that the GIS and GIA has informed the master planning of the Key Site allocations (6.395). To ensure this approach is carried forward for other development proposals, we consider there should be a stronger “policy hook” within Policy SP19 to link the content and evidence of the GI work to the policy and its influence on decision-making. Without this we consider there may be a risk of a policy gap/mismatch when determining planning applications.
This could be resolved by a new criterion such as:
“the provision of green infrastructure must have regard to any adopted or emerging guidance including the Green Infrastructure Strategy/Green Infrastructure Assessment
(and the Assets listed therein), and Green Infrastructure (Action) Plan for the Vale.”
To strengthen Policy SP19 we also recommend an addition to the wording of criterion 2 to read:
“Protect and enhance connectivity between existing green infrastructure assets and be planned wherever possible to positively support areas of high ecological value”.
We furthermore note that criterion 3 of SP19 refers to achieving net benefit for biodiversity whilst the policy overall seeks to provide, protect and enhance high quality multi-functional green infrastructure. We have previously commented that multi-functional green spaces may not always be compatible with biodiversity. It should be recognised that multifunctional uses of space can be to the detriment of the natural environment and so must be carefully considered. We recommend that paragraph 6.397 wording is updated to reflect this potential conflict so that NBB required by PPW (and as promoted by para 6.396 together with Policy SP20) is able to be prioritised and not compromised.
This point could also be raised under Policy SP4 Placemaking – at para 6.32. It should not be assumed that multifunctional spaces will also be delivering for nature in every situation and in some cases separate provision of spaces to meet biodiversity goals will be essential.
Paragraph 6.401 is welcomed regarding the opportunities that exist for the protection, maintenance and further enhancement of green infrastructure assets.
Strategic Policy 20 (SP20) – Biodiversity and Ecosystem Resilience
We welcome the inclusion of SP20 which recognises the importance of natural assets and aims to protect these. We have made comments regarding the term “high ecological value” in our Summary section at the start of this letter.
We also note that whilst reference is made to sites and areas of European, national and local importance (para. 6.402), this is not distinctly carried through within SP20 or within a specific detailed policy in the deposit plan. We advise that a more detailed policy for the Natural Environment (similar to DNP4 for the Historic Environment) could be included within the deposit plan and this should include reference to the protection of statutorily designated sites. Alternatively, SP20 itself could be updated to include reference to these in a similar manner to the approach taken to non-statutory designated sites provided by criterion 5 of SP20. We consider this would strengthen the deposit plan’s alignment to
section 6.4.3 of PPW12. This issue is also reflected in our feedback to the ISA as set out in Section 2.
By adding a detailed policy for the wider protection of the natural environment, there is scope to ensure a clearer message within the deposit plan regarding the need for natural resources (including land, air, water and soils) in the Vale to be protected for themselves and the essential ecosystem services they deliver. This is opposed to merely preventing pollution (deposit plan Policy DNP5). Taking such an approach would enable an
opportunity to add the consideration of Sustainable Management of Natural Resources (SMNR) into the plan policy framework rather than confining this to the deposit plan context (para 2.11) and the policy context of the GIS (page 53).
We note that Policy CC4: Renewable, Low and Zero Carbon Energy Generation is more distinct in seeking to safeguard a range of assets (including nature conservation interests and soil conservation interests) and we consider a similar policy approach may be useful
for all development proposals. We also suggest that the placemaking strategic policy (Policy SP4) could be altered in order to highlight the Natural Environment alongside its
current reference to the Historic Environment. We note that placemaking principles (Figure 11 - Identity) includes the need for development to respond to natural physical attributes of the site. This is an issue is linked to our site-specific comments (Section 4 below) where we cite, for example, the need to buffer woodlands, hedgerows and watercourses and preserve linear corridors.
Ensuring an SMNR approach will impact positively on the ground to safeguard and improve ecological networks and protect and enhance ecosystems, essential to meeting
the nature emergency. Topics we draw your attention to include river restoration where, in particular, the removal/remediation of physical modifications can make a significant impact upon water quality. The GIS provides scope to capture various projects and wider initiatives, including those based on catchment scale improvements and we welcome the opportunity to be continually involved in this work. We note and welcome the recognition of
nature-based solutions within Policies SP16, SP19 and SP20 and in detailed Policy CC6.
With regards to natural assets and water resources, we consider that specific reference to water quality is lacking within the strategic and/or detailed policies. Whilst we note that water quality is mentioned within criterion 9 of Policy SP16, we consider the deposit plan should include more direct reference to the Water Framework Directive. We consider there is an opportunity for SP20 to be updated to ensure developments protect water quality and quantity. Alternatively, as mentioned above, this could fit within a detailed policy for the protection of the natural environment.
As a minor point, please note that the South Central Area Statement is not hyphenated (para 2.10 and 2.11). Please note also that, referring to paragraph 6.404 and 6.405, the
requirements for developments to demonstrate NBB is based on PPW12, rather than The Environment (Wales) Act 2016.

Detailed Policies

Infrastructure
Whilst we note that the infrastructure requirements (such as sewerage capacity) have been investigated for certain key sites within the deposit plan, we consider there could be scope for a detailed policy to cover infrastructure requirements for all development.

Policy DNP7
We welcome Policy DNP7 of the deposit plan, which recognises the importance of preserving the natural darkness of the night sky and minimising light pollution, which we consider to be important in limiting adverse impacts upon local biodiversity and ecological
connectivity.

Policy DPN8
Please refer to comments made with regards to this policy under Section 6: Habitats Regulation Assessment (HRA).

Policy HG5 - Affordable Housing Exception Sites
We advise that, particularly given these sites are permissible outside of settlements and could be in countryside locations, criterion 6 should be amended to:
“There is no loss of land with significant recreational, amenity, agricultural, ecological or natural heritage value”.

EMP1 – Employment Regeneration Opportunity Areas
We note that the Former Aberthaw Power Station has been identified as an employment regeneration opportunity area. There are otter and water vole records on the site and we are aware of GCN records within the local area. We would advise against the inclusion of
the Aberthaw Nature Reserve within the allocation and advise that any application on the site would need to be supported by up-to-date ecological survey information and
appropriate conservation measures. Given the nature of the site, future applications will also need to be supported by appropriate land contamination investigations.

CC3 – Renewable Energy Local Search Areas
This policy identifies several sites where the potential for wind and solar development are the greatest (known as ‘search areas’). There are significant search areas located between Llantrithyd and St Hilary; no ecological information has been provided for these search areas, however given the records for GCN, water vole and otter local to these areas, it is likely that provision in the form of suitable habitats will need to be made for these species.
This could be substantial in scale, however without further ecological information we cannot advise further at this time. Notwithstanding, given the scale of the search area in this location and the likely ecological impacts, we advise that this area would benefit from spatial planning of biodiversity provision, at a greater than individual site scale.

Paragraph 2.81 – The Vale Nature Recovery Action Plan
We note reference to ‘6 broad habitat types’ including Woodland, Freshwater, Grassland, Coastal, Agriculture and Urban. We suggest this is amended to ‘6 broad ecosystems’ to reflect correct terminology and the State of Natural Resources Report 2025.

4. Strategic Sites
Overview
We previously provided detailed comments on the RLDP’s Strategic Sites, as set out in our response ref: CAS-234819-C1V3, dated 4th October 2023, which we refer you to. We welcome the additional information provided and note the inclusion of Green Infrastructure
Strategies for each of the Key Sites. However, we note that these do not include reference to protected species specifically and as a result we are unable to confirm that the provision for each site is appropriate. We observe that the road infrastructure for many of these sites severs woodlands and other substantial linear corridors. We advise that such sites are designed to minimise fragmentation in the landscape and advise that the road layouts and consequent severance is re-visited.

KS4 and KS5 are located within the vicinity of St Athan. This area is important for (and we are aware of) multiple records of GCN and dormice. Some of the area is already secured as compensation for impacts on these species associated with previous developments. We advise that the wider St Athan area is subject to spatial planning of biodiversity provision at a greater than individual site scale (as we have referenced in the Section 1 of this letter), in order to determine that:
• It does not cause detriment to the maintenance of the favourable conservation status of both GCN and dormice (strategic conservation plans should be established for both species);
• To ensure that green spaces and infrastructure are meaningfully spatially connected and sufficient in size;
We consider piecemeal development of these areas will not lead to effective conservation delivery and will cause the delivery of these sites to be less effective during the planning process.

Spatial Planning of Biodiversity
A masterplan or spatial biodiversity or GI plan should demonstrate the retention, provision and enhancement of essential areas for protected species. It should ensure that individual site-based habitat provisions are not designed in isolation but considered in association with nearby sites to demonstrate how habitat connectivity and resilience will be provided both across the site and to the wider landscape. Note that functional separation of public
open space and areas for biodiversity compensation may be required. Suitable buffers will need to be applied to any woodland and retained or created habitats on site. A sensitive lighting strategy will also likely be required for these sites. This point was raised previously during our review of the strategic candidate sites (ref: CAS-234819-C1V3, dated 4th October 2023).

Updated Surveys and Appropriate Buffer Zones
Further to the above comments, we welcome reference within the Infrastructure Delivery Plan for the requirement for updated ecological surveys and appropriate buffer zones to watercourses and retained habitat features for KS1 and KS2. Given the various ecological
constraints for each key site, we consider this advice should be included for each of the key sites.

Site Specific Comments
KS1 – Land at North West Barry
Protected Species – Dormice and bats are present on site. We advise that the masterplan is informed by surveys to ensure that biodiversity interests are maintained and enhanced. The site may require some areas to be retained an/or provision for habitats to support them. Dark areas and/or bespoke lighting scheme may also be required at project stage.
Protected Sites – The site is located in close proximity to Walters Farm and Barry Woodlands SSSI. As raised in our previous responses (CAS-234819-C1V3, dated: 4th
October 2023 and CAS-276923-N7H6, dated 17th April 2025), we have some concerns with the potential for increased and inappropriate use of the protected sites through recreational activities. We welcome that requirements have been detailed within HG1 KS1
under Green Infrastructure, Recreation Spaces and Biodiversity, which includes reference to emerging guidance for Suitable Alternate Natural Greenspace (SANG).

KS2 – North of Dinas Powys, off Cardiff Road
Protected Species – We note the supporting Preliminary Ecological Appraisal (PEA) (13th September 2022) which identifies potential for this site to support GCN, dormouse and bats. In the absence of species specific surveys, we are unable to advise whether the housing number aspirations for the site are realistic. We advise the scheme is designed to minimise severance of ecological corridors.

KS3 – Land at Readers Way
Protected Species – GCN are known to be present on this site (Readers Way Pond). The current masterplan indicates that the pond will be surrounded by built development and therefore built upon much of the terrestrial habitat which supports this pond. It is essential
that the masterplan provides a wide corridor from this pond to the wider countryside, other than via the closely managed grassland at Cardiff Airport. Any masterplan should make provision for this and any loss of habitat should be compensated for.

KS4 – Land at Church Farm
Protected Species - There are records of dormouse and GCN in the wider area. However, the supporting PEA indicates no direct impacts on the latter of the species. There appears to be extensive green space proposed in the illustrative masterplan, which we support.

KS5 – Land to the West of St Athan
Protected Species - The St Athan area is important area for GCN and dormouse. We would generally concur with the lower risk assessed for these species in association with this site. However, this is a substantial site and this and other sites in the St Athan area would benefit from spatial planning of biodiversity provision at a greater scale as reaffirmed elsewhere in this response.

5. Housing And Employment Allocations
Housing Allocations

HG1 (1) Land to the West of Pencoedtre Lane
Protected Sites: The site is within close proximity (200m) to Barry Woodlands Site of Special Scientific Interest (SSSI) and there is a risk from increased recreational use as a result of residential development, which could lead to impacts on the SSSI. Green space design must consider any emerging guidance for SANG to reduce recreational pressure on adjacent sites of biodiversity importance.
HG1 (2) Land at the Mole
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary European Marine Site (EMS). A HRA at project level will therefore be required.

HG1 (3) Land at Hayes Lane
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

HG1 (4) Land at Neptune Road
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

HG1 (5) Land between the Northern Access Road and Eglwys Brewis Road (Site C - Central Parcel)
Flood Risk: The site is located partially within Flood Zone 2 and 3 for Rivers, with the southern area of the site located within Flood Zone 3. We refer you to Sections 10.20 and 10.21 of TAN 15, which state that highly vulnerable development in Zone 3 should be avoided. Notwithstanding, we acknowledge that at masterplanning stage, there is scope to locate residential development away from areas of flood risk. We also welcome that
Appendix B of your Infrastructure Delivery Plan notes the requirement for an FCA at project level for this site.
Watercourse: Boverton Brook (Main River) runs through the site and any development will need to ensure no adverse impacts to the watercourse with appropriate buffers and design considerations.

HG1 (6) Land adjoining St Athan Road
Land Contamination: The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.

Rural Affordable Housing Led Sites
HG4 (1) Land to the East of Colwinston
Land Contamination: The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.

Major Employment Allocations
SP14 (1) Land east of Cardiff Airport, Rhoose
Protected Species and Protected Sites: The site is within close proximity (360m) of Barry Woodlands SSSI and there also appears to be significant potential for the site to support dormouse, GCN, otter and water vole. There are large areas of semi-natural habitats associated with this site including woodland, mature hedgerow and watercourses. These should be retained and significantly buffered from development. Connectivity between the
site and the wider environment should also be maintained. It is therefore currently not possible to advise whether the full aspirations of the site could be fulfilled.
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (2) Land south of Port Road (Model Farm), Rhoose
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (3) Bro Tathan Aerospace and Business Park
Protected Species: The site is located within an important area for GCN and dormice. As mentioned, this area would benefit from spatial planning of biodiversity provision at a
greater scale to better inform allocation.
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (4) Land to the South of Junction 34 of the M4, Hensol
Protected Sites: The site is located directly adjacent to Ely Valley SSSI. Given the biodiversity interest at the site, previous applications at the site include planning
commitments to conserve and enhance grasslands habitats on the site. These commitments have not yet materialised and the requirement for these provisions should be noted within the LDP.
Flood Risk: The site is located partially within Flood Zone 3 for Sea. We advise that an FCA will be required at project level to determine any flood risk implications at the site.

Local Employment Allocations
SP14 (5) Atlantic Trading Estate, Barry
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination. The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

SP14 (6) Windmill Park, Hayes Road, Barry
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination. The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.
Flood Risk: The site is located partially within Flood Zone 3 for Sea. We advise that an FCA will be required at project level to determine any flood risk implications at the site.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

SP14 (7) Vale Business Park, Llandow
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (8) Land at Llandow Trading Estate
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

6. Habitats Regulations Assessment (HRA)
Marine and Coastal Physical Processes
Coastal Squeeze
We note that coastal squeeze has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is that it “is unlikely that the Vale of Glamorgan RLDP will allocate many developments on
greenfield sites adjoining the estuary”.
We also note that Policy CC6 specifically relates to Coastal Defences and Shoreline Management, with reference to the Shoreline Management Plans. We recommend the use of NRW’s Assessment of Coastal Squeeze at the project level for anyone proposing to
undertake works to coastal structures.

Loss of Functionally Linked Habitat
As part of the Preferred Strategy consultation, we advised that consideration was given to potential impacts on migratory fish features of the Severn Estuary EMS. In particular, we referenced the River Ely and its tributaries providing supporting habitat for essential life cycle processes of some or all the diadromous fish species.
Within the deposit plan HRA, it is noted that likely significant effects to the migratory fish features of the Severn Estuary EMS has been ruled out, as none of the sites allocated in the RLDP lie in close proximity to the River Ely and connected watercourses. We therefore
agree with this conclusion.
In relation to bird features, Table 8 of the Appropriate Assessment identifies many key sites and allocations with high to medium potential for functional linkage to the Severn Estuary EMS. We note that loss of functionally linked habitat has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is the inclusion of ‘Policy DNP8 – Severn Estuary Recreational
Pressure’ within the deposit plan.

Policy DNP8
We advise that clarification is needed in relation to this policy, as while we welcome the supporting text regarding functionally linked land outlined in paragraph 6.76 of the HRA, the policy is mainly focused on recreational pressure and is titled as such. We also note a discrepancy between the policy wording in paragraph 6.76 and Policy DNP8 in the deposit plan itself.

Visual and Noise Disturbance (During Construction)
Within the deposit plan HRA, visual and noise disturbance has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is through the inclusion of recommendations outlined in 6.83 of the HRA to the supporting text of Policy SP20, which we welcome.
We also welcome the recommendation in relation to potential functionally linked land as outlined in paragraph 6.84 of the HRA.

Recreational Pressure
Within the deposit plan HRA, recreational pressure has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. Again, the justification for this is the inclusion of ‘Policy DNP8 – Severn Estuary Recreational Pressure’ within the deposit plan, which as above, we advise needs
clarification.
We note that no visitor data has been collected from access points within the Vale of Glamorgan, but we welcome reference to the visitor surveys undertaken by
Monmouthshire and Torfaen, as well as the 2022 visitor survey commissioned by Stroud District Council.
We note that paragraph 6.25 of the HRA states that “three Key Sites and several other housing allocations lie within the 12.6km core recreational catchment that has been
deemed most appropriate for the Severn Estuary SAC/SPA/Ramsar”. However, we also note that Table 6 in the HRA only includes two Key Sites requiring mitigation, with KS3 being omitted. We advise that clarification is needed at the project level as to whether developments are situated within the 12.6km catchment area.

7. Strategic Flood Consequence Assessment (SFCA)
We have reviewed the submitted SFCA and agree with the scope of the assessment made.
We note there is currently an upper catchment Natural Flood Management (NFM) / Nature Based Solutions (NbS) project on the Cadoxton to reduce flood risk to Dinas Powys, Any updated SCFA should have regard to NFM schemes being progressed in their area and
proposals should be clearly outlined in the Development Plan (in accordance with TAN 15 2025).

8. Green Infrastructure Strategy (GIS)
We understand that the published GIS has not been updated to reflect the latest stage of the deposit plan and refers only to the preferred strategy stage (para 2.2.3). We previously provided advice on the Green Infrastructure Assessment (GIA) (re: CAS-252087-F0H1, dated 14th May 2024) which is included within the GIS. We refer you to these comments, noting that the GIS will be kept under continual review (para 1.2.5).

This submission relates to the site known as ‘Land North of Dinas Powys’ and builds upon previous responses provided in respect of the Call for Sites exercise in September 2022 and more recently Preferred Strategy in February 2024.
For context the site is identified as part of Candidate Site Ref. No 444 within the latest Candidate Sites Assessment (Background Paper – BP18A) which has been published as part of the supporting evidence base.
As you are aware to date Persimmon have presented, what is in effect, two options for the development of the site with a Smaller Option (extending c13ha) and an Extended Scheme (extending to c31ha). Whilst there are significant benefits of both schemes this representation will focus on the smaller option which has been identified as a proposed site allocation for residential development within the Deposit under Policy HG1 – KS2 ‘Land North of Dinas Powys’.
Having reviewed the Deposit Plan it is evident that the document is structured around a number of key themes/ sections. For convenience this submission discusses each of which in chronological order and should be considered in conjunction with the accompanying technical reports/ plans provided to date.
The overarching purpose of which shall be to respond to the relevant draft Replacement Local Development Plan policies, with particular consideration given to the Welsh Government’s tests of soundness as set out within the Development Plan Manual for Wales (Third Edition) March 2020)):
• Test 1 – Does the Plan Fit?
• Test 2 – Is the Plan Appropriate?
• Test 3 – Will the Plan Deliver?

Section 3: Key Characteristics
Settlement Pattern
In principle, Persimmon support the Settlement Pattern as set out in Section 3 and in particularly the identification of Dinas Powys as a Primary Settlement.
Paragraph 3.9 explains that primary settlements “offer several key services and facilities, which are vital to their role as sustainable communities, as they reduce the need to travel to Barry or the Service Centre Settlements to address day-to-day needs”.
The importance of the Primary Settlements in supporting the Service Centre Settlements is noted, however Persimmon consider that Dinas Powys, in particular, is capable of a higher role/ function and thus accommodate even further levels of growth. This is particularly relevant given the fact that the Service Centres at Cowbridge, Llantwit Major and Penarth are generally more constrained physically and environmentally.
Housing Market and Housing Need
In light of the Vale of Glamorgan’s strategic location in-between Cardiff and Bridgend, and the significant employment opportunities associated with these areas, the Deposit RLDP should seek to maximise housing provision to ensure a more sustainable balance is achieved between homes and jobs, and in turn reduce commuting distances/ carbon emissions.
Paragraph 3.18 clearly acknowledges the scale of affordable housing need, identifying a requirement for 1,075 affordable homes per annum between 2023–2028 and 154 per annum thereafter. Yet it remains unclear whether existing unmet need has been fully factored into the overall housing requirement presented within the Deposit RLDP. This is particularly importance in the context of the Welsh Government’s 2025-based estimates which identify 9,400 units of unmet need at a national level and a requirement for 8,700 additional homes per annum over the next five years simply to address newly arising need.
Accordingly, there is a compelling justification for a further uplift in housing numbers to ensure the Plan proactively addresses both existing and emerging need. Increasing the overall housing requirement would directly enhance the overall delivery rate for affordable homes which is crucial in a local authority area with the highest affordability ratio in Wales. Paragraph 3.17 confirms that in the Vale average house prices are 9.7 times average workplace earnings compared to the Wales average of 6.1, therefore a step change in housing targets is needed to support a more balanced housing market across the region.
Section 4: Key Themes, Vision & Objectives
Key Themes
Persimmon supports the theme ‘Homes for all’ and the need for the housing supply to respond to the growing population and provided in appropriate locations, with a mix of tenure and types. In that respect site Land north of Dinas Powys provides an opportunity to ensure future residential development aligns with such objectives to deliver high quality housing development in a sustainable location, whilst also facilitating additional services and facilities as part of the proposed offer.
In principle, Persimmon support the ‘Placemaking’ theme and consider that the proposed allocation in Dinas Powys shall ensure a strong sense of identity is achieved.
Persimmon also support the theme of ‘Promoting active travel and sustainable transport choices’, and highlight that the proposed residential development at Dinas Powys clearly further assists in ensuring that the new development be in a highly sustainable location with very good access to alternative transport, other than the private car.
Vision
In general, Persimmon support the RLDP Vision, however highlight that whilst Barry and other Sustainable Service Centres are identified as playing a vital role in delivering the strategy, the importance of the ability for Primary Settlements to deliver sustainable and high-quality residential development also needs to be suitably recognised.
The site Land north of Dinas Powys clearly aligns with the Council’s ambition to ensure future growth delivers homes which caters for all (including affordable homes) and are prioritised in areas of greatest demand. Whilst simultaneously facilitating much needed additional infrastructure improvements to further enhance Dinas Powys’ role as a Primary Settlement thereby supporting both existing and future residents.
In light of the above it is considered that Dinas Powys plays a significant part in delivering the Council’s strategy and the role, function, and ability of this settlement to accommodate growth needs to be significantly reinforced. The settlement is capable of accommodating more growth in a highly sustainable location we believe warrants greater recognition within the vision itself.
Strategic Objectives
Objective 3 – Home for All
Persimmon supports the principle of Objective 3, in particular the provision of high quality housing which includes the right mix, tenure and type. Persimmon supports the notion of providing residential development in places which people want to live, and in particular Dinas Powys as a Primary Settlement.
Objective 4 – Placemaking
As above, in principle Persimmon support the Council’s placemaking objectives which seeks to ensure all development will contribute positively toward creating a sense of place. Most notably this involves prioritising future growth in sustainable locations which are placed to create attractive, safe and accessible schemes that are equally effective from a functional standpoint.
Our site in Danis Powys aligns with such principles whilst also providing an opportunity to facilitate a logical extension to the existing urban form and in doing so meet local need in a sustainable matter. The scope of which includes full market and affordable housing in accordance with proposed policy requirements along with ample public open space, active travel links via dedicated pedestrian footpaths and cycleways and SuDS features.
Objective 8 – Promoting Active and Sustainable Travel Choices
Persimmon supports the principle of promoting active and sustainable travel choices and highlight that their residential development at Dinas Powys has been designed to ensure accessibility it’s at the heart of the scheme with regards to walking, cycling and connectivity to public transport.
Moreover, the proposed allocation would also facilitate both on-site and off-site infrastructure improvements further enhancing the existing excellent accessibility to Eastbrook Station. Therefore, providing an opportunity to encourage a modal shift towards more active forms of travel and consequently reducing dependency on private vehicle and associated carbon emissions. From a plan-making standpoint the proposed allocation at Land north of Dinas Powys (HG1 KS2) is therefore crucial to ensure growth is prioritised in such a highly sustainable location and maximise opportunities for greater connectivity at both a regional and local level.
Section 5: Sustainable Growth Strategy
RLDP Sustainable Growth Strategy comprises six key elements as follows:
1. Delivering a sustainable level of housing and employment growth supported by appropriate infrastructure that accords with the Vale’s position within the Cardiff Capital Region (CCR).
In order to meet the overarching Vision, the Vale have identified a need to deliver at least 8,679 new dwellings over the proposed plan period which responds to the identified housing requirement of 7,890 homes (526 per annum) and incorporates a 10% flexible allowance. Persimmon support the proposed approach, however maintain it should be considered a minimum figure with aspirations to achieve greater levels of growth in sustainable locations across the district.
Whilst we appreciate these figures are based on average completion rates over the first ten years of the adopted Local Development Plan. It is important to recognise that a higher rate of housing delivery is demonstrably achievable. Annual completion rates peaked at 917 dwellings, with six of the ten monitoring years exceeding the 526 per annum figure currently relied upon. This demonstrates that delivery capacity within the Vale has historically operated well above the proposed requirement and should therefore provide confidence that a higher housing target could realistically be achieved over the emerging plan period.
Furthermore, the Council’s own evidence base (BP7 - Housing and Employment Growth Options) identifies a five-year average build rate of 780 units per annum between 2016 and 2021. Again, this figure exceeds the annual delivery rate currently proposed within the emerging RLDP and reinforces the fact that the proposed housing requirement should not be unduly constrained by a lower long-term average.
Whilst Paragraph 5.8 explains that the proposed figures are based on a ten-year average delivery rate, it fails to acknowledge that this period included the Covid-19 pandemic and at a time where construction costs experienced significant inflation. These factors had a material impact on the housebuilding industry nationally and inevitably suppressed delivery rates during those years. From an objective perspective, basing the future housing requirement on an average that includes these exceptional circumstances risks skewing the figures and underestimates the district’s true delivery potential for the Vale.
In light of the above we believe a sensible response would be to incorporate a greater flexible allowance of 15% within the RLDP to demonstrate an appropriate level of growth will be achieved. Whilst also ensuring there is sufficient supply of sites to come forward early on during the plan period to proactively address housing need from the point of adoption up to 2036.
From a procedural standpoint it is also important to note that the currently adopted plan predates the publication of Future Wales: The National Plan 2040 and the Vale’s position within a national growth area. As such, pursuing an approach which seeks to maintain historic delivery rates is not considered to reflect this enhanced role and arguably lacks the level ambition set out at a national level. The proposed housing requirement should therefore be uplifted to positively respond to such matters in order to ensure conformity with Future Wales and regional aspirations.
Increasing the overall housing target would also act as a catalyst to enhance the delivery of affordable housing which is identified as a key objective for the RLDP. Each proposed site allocation is subject to a policy-compliant percentage contribution, therefore a higher level of market housing would proportionately generate a greater number of affordable homes to meet local need across the region.
As evidence above, the proposed allocation Site Ref HG1 KS2 – Land to the North of Dinas Powys, represents a suitable, available and deliverable location for residential development without any constraints preventing it from delivering units in the first five years of the emerging plan period.
Persimmon Homes remain fully committed to the development opportunities presented by the site and its progression as a proposed allocation within the RLDP. The latter is essential in assisting the Vale of Glamorgan meet local housing need which ultimately goes to the heart of the plan and ensuring it has been soundly prepared.

2. Aligning locations for new housing, employment, services and facilities to reduce the need to travel.
Persimmon supports the Vale’s objective to locate new major development in areas of the region best served by existing infrastructure and supporting services. The Settlement Appraisal Review (BP5) identifies Dinas Powys as the most sustainable primary settlement in the region with suitable local services to accommodate future growth which remains in keeping with the overall function of the existing settlement.
Whilst the settlements of Barry, Penarth, Llantwit Major and Cowbridge are deemed to score higher on certain criteria (as shown within the table below), it is clear Dinas Powys is considered to be the third most accessible settlement to modes of public transport which clearly aligns with the Council’s intension to pursue a transport orientated spatial strategy for future growth. On this basis it is evident that Dinas Powys is more sustainably located when compared to Cowbridge and Llantwit Major, and therefore warrants a higher ranking within the Settlement Appraisal Review and thus greater levels of growth within the RLDP.

3. Focusing development at locations that are well served by existing and proposed rail stations as part of the South Wales Metro and in areas with good bus links.
The Deposit RLDP explains that whilst reducing the need to travel is a key policy objective, it is recognised that there are journeys that will need to be made by other modes of transport, particularly due to the strong relationship with Cardiff as a designation for employment, retail and entertainment. As such the proposed growth strategy seeks to locate development in places that are inherently well served by sustainable transport in line with the Vale of Glamorgan’s transport hierarchy.
Persimmon supports these principles and recognises the importance of prioritising development in sustainable locations across the regions, particular those well connected to Cardiff city centre. Paragraph 5.18 of the Deposit Plan states that “Targeting new development to the settlements that are served by the rail network is a key part of the strategy, as it will facilitate journeys being made by means other than the car”. Persimmon wholly agree with this approach on the basis that this would enable the RLDP to achieve a more sustainable pattern of development and in doing so support growth over the emerging plan period.
In order to help identify suitable locations for future development Transport for Wales have produced isochrone maps which delineates different travels times for walking and cycling around each of the existing railway stations in the Vale. Most notably the site known as at ‘Land North of Dinas Powys’ is situated within 5-10 minutes walking / 0-5 minutes cycling distance to Eastbrook Station and 15-20 minutes walking/ 5-10 minutes cycling distance from the station at Dinas Powys. This evidence clearly demonstrates the proposed site represents one of the most sustainable locations for residential-led growth and thereby justified its position within the RLDP as a key allocation.
Land North of Dinas Powys further strengthens the spatial strategy by prioritising development at a location that is well served by existing rail stations. Focusing growth in settlements with established rail connectivity ensures that future residents have direct access to sustainable transport infrastructure from the outset. This approach supports a more sustainable pattern of development by reducing reliance on the private vehicle and encouraging a modal shift towards rail, alongside walking and cycling for local trips.
By directing development to locations well served by existing bus and rail infrastructure , the proposal would help reduce the need for commuting via private vehicles, particularly for journeys to key employment and service destinations. In doing so, it would make a positive contribution towards the Council’s climate change targets through the reduction of carbon emissions and promoting a modal shift within the local community.
Moreover, the proposed allocation HG1 KS2 presents a significant opportunity to support local facilities and facilitate green infrastructure provision within a highly accessible and sustainable location. The scope of which shall include ample public open space, dedicated active travel links via pedestrian footpaths and cycleways, Sustainable Drainage Systems (SuDS) features, and other associated infrastructure. Integrating these elements at the heart of the site shall enable residents to meet a greater proportion of their daily needs locally while benefiting from high-quality public transport connections.
In terms of the overall distribution of growth, Persimmon fully supports the proposed approach to prioritise development in sustainable locations near existing rail infrastructure as depicted by the strategic transport corridor within the RLDP Key Diagram (Figure 10). However, to optimise the effectiveness of this strategy it would be prudent to focus growth in areas of greatest demand.
Paragraph 3.14 of the Deposit Plan explains that a significant proportion of the population increase in the Vale over the past 10 years has been as a direct result of a people migrating from Cardiff to the Vale, with the Vale ultimately experiencing a net increase of an average of 716 people per year for the period 2011-2021. These principles should therefore be better reflected in the general pattern of development set out within the RLDP. This would be achieved by prioritising higher levels of growth in areas such as Dinas Powys, which is not only the nearest settlement geographically to Cardiff but also inherently well connected by the existing rail network and other modes of public transport.
Focussing further growth in well-connected, sustainable locations such Dinas Powys will therefore support the Council’s transport-led placemaking approach. These principles fully align with the Welsh Governments strategic objectives as set out within the Future Wales – the National Plan 2040, Planning Policy Wales Edition 12 and Llwybr Newydd: The Wales Transport Strategy, which in turn shall contribute towards achieving a more sustainable pattern of development within the RLDP.

Figure 1. Extract of Key Diagram/ Strategic Growth Area from Deposit Plan
Section 6: Policy Framework
This section identifies the strategic policies, criteria-based development management policies, site specific allocations and designated areas to be protected. These are broadly arranged by topic theme under the key policy headings set out in PPW which are reflected below.
Strategic and Spatial Choices (Placemaking)
Policy SP1 – Sustainable Growth Strategy (& Policy SP6 – Housing Requirements)
This policy states that in order to deliver the Sustainable Growth Strategy for the VoG, the emerging RLDP will make provision for 7,890 dwellings and 5,338 jobs over the plan period. In order to achieve the former Policy SP6 explains that to meet the identified housing requirement of 7,890 dwellings, provision will be made for the delivery of 8,660 homes in the Plan Period 2021 to 2036 which incorporates a 10% flexible allowance. In turn this will be distributed as follows: i) 3,837 dwellings from the existing land supply; ii) 3,520 dwellings on allocated sites; & iii) 1,303 dwellings from large and small windfall developments.

Whilst Persimmon supports the Council’s conclusion that in principle the ‘Medium’ growth option reflected in Policy SP1 generally accords with the Welsh Government’s aspirations for the Vale of Glamorgan within the Future Wales national growth area, which is identified as a focus for strategic economic and housing growth. Given the Vale forms part of the Cardiff Capital Region, it is equally important that the overall level of growth remains suitably ambitious to support the region’s economic aspirations and continues to complement Cardiff which remains the nearest neighbouring authority.
Although we understand the proposed approach uses the Dwelling-led 10 Year scenario, which is based on the average annual build rate for the first 10 years of the adopted plan and equates to a total of 7,890 new homes or 526 dwellings per annum over the emerging plan period. The overarching intention is to ensure the projected level of growth is deliverable whilst recognising the fact there is sufficient capacity within the Vale to support further growth towards the higher end of the ‘medium’ range.
As noted, Persimmon are wholly in support of Key Housing-Led Site Ref. KS2 - North Dinas Powys, off Cardiff Road, which seeks to actively contribute towards the housing requirement.
However, the Deposit Plan also needs to recognise that there exists an opportunity to further extend the allocation to provide a logical extension to the defined urban area of Dinas Powys and which will facilitate the delivery of much needed full market and affordable housing to help address the significant level of demand identified across the Vale.
This additional land is promoted in the context of the concerns raised regarding the current figure of 8,660 new dwellings which is underpinned by a 10% flexible allowance in relation to housing delivery. Persimmon consider it relevant to take account of recent evidence provided to other Local Planning Authorities in Wales which have either adopted or are in the latter stages of bringing forward a new Local Development Plan.
For example, in Bridgend the Council recently adopted their new Local Development Plan (covering the period 2018 to 2033) which is underpinned by a flexibility allowance of 14% equating to an additional 1,053 dwellings. This level of provision was required in order to demonstrate the Anticipated Annual Build Rate (AABR) were deliverable and ensure that the Plan remains effective in the event of changing circumstances. During the examination process the Inspector explained that an increase beyond the standard 10% was fundamental to enable the plan and its housing trajectory to be resilient and sufficiently adaptable. The overarching purpose of which is to account for any unforeseen changes and potential shortfalls/ delays to the strategic site allocations whilst still enabling the overall housing requirement to be delivered.
For Swansea, the Council published their LDP2 Pre-Deposit Plan (Preferred Strategy) for consultation last year. In terms of housing delivery this incorporates a 20% flexible allowance above the proposed housing requirement and is predicated on the basis of needing to account for certain sites not coming forward as anticipated and other unforeseen factors affecting delivery. Similar to the Vale, Swansea City Council’s latest Annual Monitoring Report (6th Edition) (October 2025) confirms that since adoption of the current LDP in February 2019 they have not met their annual housing target for any of the past six years. To date this has resulted in a shortfall of approximately 3,767 homes which is predominantly attributed to delays associated with larger strategic allocations. Therefore, in order to avoid having similar implications next time around the Council have uplifted the proposed flexible allowance within LDP2 and intend to incorporate a more diverse portfolio of sites going forward. The main purpose of which is to build in an additional margin of flexibility above the standard 10% threshold, and therefore enable other sites to come forward to account for potential slippage elsewhere to ensure the plan is effective in meeting local need.
More recently in Monmouthshire, the Council submitted their proposed RLDP to PEDW in November 2025. As part of which they have identified a requirement of 6,210 homes which incorporates a 15% flexible allowance. Similar to above an increase beyond the standard 10% threshold has been justified to account for potential shortfalls/ delays due to longer lead in times needed for strategic site allocations whilst proactively addressing any historic unmet need.
Whilst Persimmon appreciate that the Council intends to prioritise growth towards the higher end of the ‘medium’ range. Having reviewed the Deposit Plan evidence base we believe a minimum allowance of 15% would be more reflective of the Vale’s strategic position and would seek an additional 395 dwellings to the medium growth option equating to a total of 9,074 homes. The benefits of which are evident above and justification well-established from a plan-making perspective to ensure the RLDP is underpinned by a robust evidence base which incorporates a suitable level of flexibility to effectively meet local housing need from the outset.
In addition to the above the importance of increasing the RLDP’s housing target, by virtue of uplifting the proposed flexible allowance, has recently been highlighted by the findings of data published by the Welsh Government (WG). Most notably that includes the 2022-based Local authority household projections (Dated 20th November 2025) and 2025-based estimates of additional housing need (Dated 12th February 2026).
Upon publishing the former superseded the previous 2018-based demographic projections and provides updated figures from mid-2022 to mid-2032. The results show that whilst the overall number of households in Wales is projected to increase by around 98,500/ 7.2%, to a total of 1.46 million. The local authorities projected to see the largest percentage increases are the Vale of Glamorgan (up 11.7%) and Cardiff (up 11.1%).
In turn these trends are carried through into WG’s 2025-based estimates of additional housing need, which identifies an existing unmet need of 9,400 homes. This is supplemented by a requirement to deliver an average of 8,700 new homes annually over the next five years to account for newly arising need alone. The combination of which demonstrates that there is an urgent need to increase delivery rates on both a national and local level, and therefore it’s imperative that the latest position with regards to the need for affordable and full market homes are accurately reflected within the Council’s housing figures.
In terms of considering the level of housing provision for a plan, Paragraph 5.34 of the DPM is explicit in that the most up-to date suite of Welsh Government Population and Household Projections must form the foundation of any evidence base. LPAs are then required to use a household conversion factor when translating households to dwellings to establish overall need.
Once again, the DPM explains that failure to include a robust conversion rate from the outset is a high-risk strategy and may undermine the overall soundness of any emerging plan. To avoid such circumstances, we believe it’s essential the LMNA is updated to reflect the latest WG datasets, which in turn is likely to provide grounds to warrant extending the proposed 15% threshold further. Ultimately this approach intends to ensure the emerging RLDP more effectively meet local need over the entire plan period and thus soundly prepared.
Figure 2. Extract of the Welsh Government’s Calculation Method for Total Dwellings as per the Development Plan Manual
As mentioned above, Policy SP6 provides a high-level breakdown of how the Council’s housing growth is expected to be delivered over the plan period. For completeness this includes: i) 3,837 dwellings from the existing land supply; ii) 3,520 dwellings on allocated sites; & iii) 1,303 dwellings from large and small windfall developments.
Whilst we do not dispute those relating to proposed site allocations and/ or windfall developments. The proportion of dwellings set to be accounted for within the Vale of Glamorgan’s existing landbank (3,837 units) is considered excessive given it represents 44.3% of the Council’s overall housing requirement.
Although Persimmon acknowledge that this is partly derived on the basis that emerging plan period has technically already commenced (2021 to 2036), and therefore is made up of sites at various different stages of planning process (i.e. either already built out, being constructed or secured consent - as shown below). It is important to recognise the potential implications this approach has in terms of stifling opportunities for growth, which is contrary to the Welsh Government’s aspirations for the Vale of Glamorgan as part of a National Growth Area within Future Wales: The National Plan 2040.

Table 3. Extract of the Vale of Glamorgan’s Housing Supply and Housing Requirement
From an objective standpoint this means there is only a need for 2,561 additional dwellings (3,520 dwellings minus 959 units rolled forward) to be delivered from new allocations over the emerging plan period. This reinforces the point that in reality the overall quantum of new homes will be significantly lower than the figure set out within the RLDP’s vision and strategic objectives. In turn this prevent opportunities for new sites to come forward as part of the plan-making process and in doing so hinder the Council’s ability to account for historic unmet need. Collectively this substantiates Persimmon’s position that in order for the plan to be considered sound the Council must accommodate a greater flexible allowance, optimising the use of sites such as Land north of Dinas Powys, to ensure the emerging local plan complies with the Welsh Government’s aspirations set out within Future Wales.
As illustrated above, the Council anticipate 1,303 dwellings coming forward in the form of windfall sites. This accounts for both small and large sites which in turn represents around 15% of the Council’s overall housing requirement. Once again, whilst we do not contest the overall windfall provision or the projected delivery rate of 87 dwellings per annum up to 2036. It is important to recognise that based on past trends the annual number of homes which comes forward on windfall sites varies significantly year on year.
Table 18 of the Development Plan Manual (DPM) is explicit in that respect and explains that although due regard must be attributed to analysis of past delivery rates, periods of abnormally high or low completions should be considered inappropriate/anomalies when extrapolating future rates of windfall sites. On that basis ensuring the RLDP incorporates a greater flexible allowance will not only provide certainty that any shortfalls/fallow periods are offset, but also enable a more consistent supply of homes to be achieved over the plan period as a whole.
Lastly, in terms of overall growth Paragraph 5.8 of the Deposit Plan states that the level of growth they have identified ‘’has been demonstrated to be deliverable and is sufficiently ambitious to reflect the Vale’s position in the Future Wales national growth area.’’ It also notes that this level of growth has been chosen so that it is ‘’complementary to, rather than competing with, the neighbouring authority of Cardiff and the wider Cardiff Capital Region (CCR).’’.
Whilst it is agreed that the level of growth may be realistic based on past trends, the claim that this is sufficiently ambitious and needs to be at this level to avoid competing with Cardiff is not substantiated by evidence to suggest that a higher level of growth could not also achieve these principles.
Cardiff, as the capital city of Wales, also demonstrated historic under delivery when publishing its deposit plan for consultation in February 2025, which was the case for allocated sites as well as generally for annual delivery rates over the adopted plan period. This resulted in a failure to meet targets over the last 10 years of their adopted plan. Whilst Cardiff has made progress in more recent years, the latest Annual Monitoring Report published in October 2025 notes that to date the region has met just 58% of its overall dwelling requirements over the plan period from 2006-2025.
Accordingly, with Cardiff opting to continue with a medium growth option for their RLDP despite these shortfalls, there is no sound basis to suggest that adopting a higher growth level within the VoG would detrimentally impact upon housing delivery or ‘compete’ with Cardiff.
In summary, Persimmon supports the overall medium growth strategy and key allocations such as North Dinas Powys. Although given the Vale’s position within the Cardiff Capital Region and its designation as a national growth area, we maintain that the proposed RLDP should be more ambitious when it comes to housing targets. Drawing on examples from Bridgend (14% flexibility), Swansea (20%), and Monmouthshire (15%), alongside evidence of historic under-delivery and recent Welsh Government household projections, there are sufficient grounds to warrant increasing the proposed flexibility allowance to a minimum of 15%, equating to a total requirement of 9,074 homes up to 2036.
These steps would help account for any potential overreliance on existing landbanks and variable windfall delivery rates which could in theory limit the plan’s ability to address unmet housing need. Overall, we conclude that a higher flexibility allowance is necessary to the ensure the RLDP is able to effectively meet local need over the plan period. From a practical standpoint whilst further sites may well be required to accommodate the additional growth, it is important the current proposed allocations are safeguarded and therefore supplemented accordingly. The benefits of which shall also demonstrate the emerging RLDP is supported by a robust, proportionate and credible evidence base to accord with the requirements of the Development Plan Manual for Wales and national growth objectives.
Policy SP2 – Settlement Hierarchy
In principle, Persimmon supports the Settlement Pattern set out in Policy SP2, particularly the identification of Dinas Powys as a Primary Settlement.
Whilst the role of Primary Settlements is acknowledged, in that they contain several key services and facilities, vital to supporting sustainable communities including primary schools, small convenience shops, food and drink outlets and employment opportunities.
Persimmon considers that Dinas Powys is capable of fulfilling an enhanced role given its proximity to strategic transport infrastructure which provide regular services to key designations throughout the region and Cardiff city centre. Whilst the proposed allocation HG1 KS2 undoubtedly supports such principles, given the area is inherently well served by existing infrastructure we maintain that it has the capacity to accommodate even further levels of growth, which could be delivered through the extended Candidate Site (Ref. No. 444). This approach would align with the Council’s spatial strategy given that the Service Centres at Cowbridge, Llantwit Major and Penarth are generally subject to greater physical and environmental constraints.
Policy SSC1 – Development within Settlement Boundaries
Persimmon Homes support the premise of Policy SSC1, and the objective of directing development to areas within defined settlement boundaries. This approach will help reinforce sustainable growth patterns and prioritise development in locations well served by both existing and planned infrastructure. Collectively these principles align with the Councils ambitions for Land north of Dinas Powys (HG1 KS2) and supporting local services and facilities to reduce overreliance on private vehicle travel.
Policy SP4 – Placemaking
In principle Persimmon Homes supports Policy SP4 and the aim of ensuring all new development is of high-quality sustainable design.
The proposed allocation Land north of Dinas Powys has been designed with landscape led approach and therefore clearly aligns with the placemaking principles set out in Policy SP4 and the sustainable placemaking framework of PPW12. The site’s location on the edge of Dinas Powys enables the scheme to positively responds to the character of the local area whilst remaining in keeping with the wider landscape setting. The layout reflects the prevailing scale and form of surrounding neighbourhoods, incorporating similar architectural cues and a coherent street hierarchy. Green infrastructure forms the structural framework of the masterplan, integrating retained landscape features, new planting, and sustainable drainage measures to ensure climate resilience and biodiversity enhancement. The density proposed makes efficient use of land in accordance with national policy while remaining sensitive to local character and the edge-of-settlement context.
In line with PPW12’s emphasis on health and well-being, the scheme promotes active travel that connects to existing pedestrian routes, public transport links and community facilities within Dinas Powys. The development prioritises walking and cycling, supports access to local schools, shops and services, and reduces reliance on the private car. Public open spaces have been prioritised towards the centre of the scheme and homes orientated accordingly to promote natural surveillance, thereby creating a safe area that encourage recreation, social interaction and community cohesion. The integrated green network delivers benefits such as improving general air quality and strengthening ecological connectivity within the Vale of Glamorgan.
The proposal also reflects the design principles set down within the Design Commission for Wales in respect of quality architectural design, contextual response and multifunctional spaces. This will be achieved through a balanced mix of housing types and tenures responds to local need. Careful consideration has also been given to the wider landscape setting of Dinas Powys, ensuring that key views, settlement edges and local character are respected and enhanced.
Policy PGD1 – Creating Well Designed and Inclusive Places
Persimmon question the need for both Policies SP4 and PGD1 as there is notable repetition between the two. In principle the criteria set out within the proposed policy aligns with our expectations, however there is a need to recognise that not all criteria will be able to be accommodated on development sites. Particularly given the need to accommodate other legislative requirements relating to environmental and economic matters that warrant equal consideration as part of the planning process.
On that basis if the Council are minded to continue with this particular policy’s inclusion, we request the proposed wording be updated to clarify that such the merit of such principles will be considered on a site-by-site basis rather than the current blanket approach suggested.
Policy PGD2 – Residential Development Densities
Residential densities are supported as a principle, however, should not be so prescriptive as to unnecessarily restrict development. Policy PGD2 outlines that residential development over 0.5ha will be permitted where the proposed density achieves a minimum of 35 dwellings per net hectare within Key, Service Centre and Primary Settlements and 30 dwellings per net hectare in Minor Rural Settlements.
From a planning standpoint, Persimmon support the Councils approach to prioritise higher density development in Key Settlements, Service Centres and Primary Settlements. These locations are naturally better connected to existing transport infrastructure, modes of public transport, Active Travel routes and local services/facilities to accommodate future growth.
A minor point in relation to the policy wording is the ‘dwellings per net hectare’ and the removal of non-developable space in any calculations. Whilst this is normal, the increased requirements relating to SAB, green infrastructure requirements and increased ecological mitigation all have a direct impact on the remaining available land and it is positive to see there is an allowance for some flexibility.
The density requirement appears to be reasonable in its approach, and the flexibility to allow individual site adjustments (as per the remaining text within the Policy) is welcomed. As there will undoubtedly be occasions where the density will need to be considered in further detail due to other on-site factors/ mitigation measures.
Possibly update to highlight support for higher net densities being prioritised in Key, Service Centres and Primary Settlements which are naturally well served by regular public transport provision and Active Travel routes, or near to services and facilities.
Policy SP5 – Creating Healthy & Inclusive Places and Spaces
Policy SP5 is supported in principle insofar as it seeks to promote healthier and more inclusive places, consistent with the objectives of Planning Policy Wales and the Well-being of Future Generations (Wales) Act 2015. However, to ensure the policy is robust and effective, it is important that it is supported by an up-to-date and clearly evidenced policy framework. In this regard, the supporting evidence base, particularly BP36 – Planning Healthy Places (June 2024), should be reviewed to ensure that the datasets referenced reflect the most recent available information. For example, life expectancy data currently cited (2018–2020) and indicators based on the Welsh Index of Multiple Deprivation 2019 should be updated where possible to reflect the most recent datasets, including the Welsh Index of Multiple Deprivation 2025 and any updated public health, active travel, air quality and demographic data. Ensuring that the evidence base reflects the latest available information is necessary to demonstrate that the policy is justified and based on an accurate understanding of local health conditions and inequalities.
The policy framework should also be updated to reflect the Health Impact Assessment (Wales) Regulations 2025, which were approved by the Senedd in November 2025 and will come into force on 6 April 2027. At present, these forthcoming statutory requirements are not referenced within Policy SP5 or the supporting guidance. Given that the regulations will establish a statutory framework for the preparation of Health Impact Assessments in Wales, it will be important for the RLDP and supporting documents to clarify how the policy’s screening, checklist and Rapid HIA requirements will interact with the statutory regime once implemented. Including reference to the regulations would help ensure that the policy remains aligned with national legislation and is future-proofed over the plan period.
The supporting Rapid Participatory HIA of the Deposit RLDP (BP3, September 2025) provides useful background regarding the Council’s engagement with stakeholders in preparing the plan. However, it would be beneficial for the Council to clearly explain how the findings of that work have informed the specific requirements contained within Policy SP5. Providing a clearer link between the outcomes of the participatory HIA and the policy approach adopted in the RLDP would improve transparency and demonstrate that the policy has been shaped by the evidence gathered through the stakeholder engagement process.
Table 4. Extract of Proposed Criteria for HIA Assessments
The emerging Health Placemaking Supplementary Planning Guidance (SPG) is broadly welcomed as a practical tool to support implementation of the policy. Nevertheless, a number of matters require further clarification prior to its adoption. In particular, whilst the SPG provides greater clarity regarding the use of the Healthy Placemaking Checklist and Rapid HIAs, it does not clearly identify the circumstances in which a comprehensive (full) HIA would be required. The SPG should also be updated to reflect forthcoming guidance from the Welsh Health Impact Assessment Support Unit (WHIASU) expected in 2026, and ensure alignment with other relevant policies and guidance, including those relating to design, travel plans, public transport accessibility and open space provision. Given the number of cross-references within the SPG, it will be important that these documents are fully aligned and consistent.
Finally, any requirement for a Health Impact Assessment should be applied on a proportionate basis, reflecting the scale, nature and likely impacts of the development proposed. The policy should therefore make clear that the scope and level of detail required for HIAs will be proportionate to the scale and type of development. Subject to these amendments and clarifications, the policy would provide a clearer and more effective framework for integrating health considerations into the planning process.

Active and Social Places
Policy SP6 – Housing Requirements
Please refer to Policy SP1 as written response also accounts for information proposed under this particular policy.
Policy HG1 – Housing Allocations
HG1 KS2 – Land to the North of Dinas Powys
Persimmon wholly support the inclusion of Land to the North of Dinas Powys (HG1 KS2) as a proposed site allocation within the emerging RLDP. The site represents a logical extension to the existing settlement of Dinas Powys and provides an opportunity to address local housing needs within a highly accessible and well-connected location. Given its position adjacent to the existing settlement boundary of Dinas Powys, the site also is also well served by existing services, public transport links, schools and community facilities, thereby reducing reliance on private car travel and supporting national and local placemaking objectives.
The proposed scheme has also been designed to make effective use of land that is both logically related to the existing urban form and clearly aligns with the Council’s growth strategy. Given the level of demand in the area, a particularly significant benefit of proposed allocation HG1- KS2 is the commitment to deliver a minimum of 100 affordable homes, representing 40% of the total provision. The site will therefore make a meaningful contribution to meeting locally needs and incorporate a mix of tenures that directly responds to the Vale’s LHMA/evidance base. These principles align with the Councils aspirations to foster more inclusive communities and thus remain consistent with Policy SP4 and Policy PGD1. From a design perspective the proposed scheme has also informed by a comprehensive masterplanning process ensuring that high quality design, integrated green infrastructure, and sustainable transport connections integrated throughout the proposed layout.
Ecological considerations have similarly informed the proposed layout for the site. Technical work, including the Preliminary Ecological Appraisal and subsequent strategy documents, have confirmed suitable biodiversity enhancements can be delivered through a network of retained and reinforced green corridors, historic woodland protection, and supplementary planting. The masterplan prioritises ecological connectivity, incorporating wildlife corridors, dark routes for nocturnal species, and extensive areas of multifunctional open space. These measures not only mitigate potential impacts on identified species, such as dormice, but provide clear opportunities for biodiversity net gain in accordance with the Environment (Wales) Act 2016. The integration of Sustainable Drainage Systems within landscaped areas further demonstrates how flood attenuation, habitat creation and recreational provision can be delivered in a cohesive manner. Thereby ensuring that environmental enhancements are incorporated throughout the scheme from the outset which fully accord with the RLDP’s objectives in that respect.
In transport and community infrastructure terms, the site’s sustainable credentials are equally compelling. The proposed access arrangements onto Cardiff Road have been refined in response to feedback from the highway department, whilst demonstrating deliverability and promoting safe access for all users to avoid having any adverse impacts on local highway network. Geographically the site also lies within immediate walking distance of Eastbrook and Dinas Powys rail stations, which inevitably aligns with the Council’s transport-orientated growth strategy. In turn these principles accord with national placemaking objectives set out in PPW12 and shall actively encouraging a modal shift away from private vehicles to incentivise more active forms of travel. Most notably this includes dedicated pedestrian and cycle links through the site providing connectivity with a range of local services and facilities.
By virtue of the above we fully support the proposed allocation of Land to the North of Dinas Powys (HG1 KS2). As the proposed developer Persimmon Homes remain committed to development opportunities the site presents and its ability to help deliver much needed full market and affordable homes in a highlight sustainable location, which clearly accord with the Council’s proposed growth strategy.
Policy HG1 (B) – Housing Allocations
HG1 (3) Barry - Land at Hayes Lane
Persimmon Homes question to suitability of allocating residential development on the site known as Land at Hayes Lane, The Bendricks. These concerns are centred on the following:
Unsustainable Location & Poor Connectivity
Whilst the site is technically identified within the settlement boundary, it is clearly not a sustainable location for residential development. This is evident by virtue of the fact that Land at Hayes Lane is situated within an existing industrial estate and lacks any supporting facilities. The former reinforces the principle that as a whole the area is characterised by a mix of light industrial and heavy industrial uses which naturally conflicts with the prospect of future residential housing. Moreover, it is reasonable to assume vehicles using the local highway network will be larger in nature (such as HGV’s), and given the majority of streets do not contain dedicated pedestrian footpaths/ cycleways, this raises concerns from a highway safety perspective.
Although we note the Transport Statement from AECOM suggests access can theoretically be achieved to Barry and Sully. Both of these settlements remain over 2km from the site and lie outside of the distances deemed acceptable by Transport for Wales (TfW) to support resident development. Allocating housing on Land at Hayes Lane which therefore does not comply with such criteria would clearly undermine the Council’s objective of pursuing a Transport Orientated Growth approach and by virtue of which risk promoting an unsustainable pattern of development within the emerging RLDP.
As outlined above given the nature of the area there are almost no existing active travel routes in this part of the region. This lack of provision would ultimately lead to future residents using alterative options and many of which would require residents to overcome physical barriers in order to travel in a more sustainable manner. For instance, due to the level of infrastructure associated with the port, the site is effectively detached from the main urban area of Barry and would involve crossing an active railway line halfway along Wimborne Road without sufficient mitigation measures in place. On the other hand, whilst Hayes Road extends further west towards Sully, it follows the southern boundary of the Polaris Industrial Estate which contains various access points that are in regular use throughout the day. Collectively these characteristics would prevent future occupants travelling in a more active manner which is in direct conflict with both local and national planning policy objectives.
The site’s geographic isolation means that access to modes of public transport are extremely limited. Most notably that includes railway stations with the nearest being Cadoxton Station which is located circa 3.8km north of the site. By AECOM’s own accord this is considered to equate to a minimum walking distance of 52 minutes which exceeds TFW’s standards for residential development. Again, this reinforces the fact future residents would be overly reliant on private vehicles to access local services (such as employment opportunities, schools, doctor surgeries etc) which in turn shall achieve an unsustainable pattern of growth and increase associated carbon emissions.
Loss of Allocated Employment Land
Crucially, the site remains allocated in the adopted LDP for B1/B8 employment uses. These intended to facilitate small industrial and workshop units as part of the Atlantic Trading Estate’s expansion and in turn support opportunities for local businesses/ enterprise ventures. The council’s latest Employment Land Review confirms a clear demand for such uses in Barry, with Land at Hayes Lane representing the most logical location for further growth. Reallocating this land for housing would therefore diminish the Vale of Glamorgan’s ability to attract sufficient economic investment to support the requisite levels of growth over the emerging plan period, and potentially displace businesses to other less suitable parts of the region which would not be in the interests of good placemaking as per PPW12.
Although the RLDP’s evidence base suggests there are other development opportunities within the region that could compensate for the proposed loss of employment land. Upon further review it is apparent these are in less favourable locations from both a strategic and operational standpoint. Reassigning Land at Hayes Lane from employment to residential would therefore undermine the Council’s objective of safeguarding existing employment land and prioritising business/ industrial uses in area’s well served by infrastructure designed to accommodate such activities (such as Barry Docks). Furthermore, it would also set a precedent for other potential losses and in doing so impact the Council’s ability to meet the region’s employment needs up to 2036.
By virtue of the above, Persimmon Homes object to the proposed allocation of residential development on Land at Hayes Lane. The principle of which is in direct conflict with the Welsh Government’s objectives set out within PPW12 & Future Wales: The National Plan 2040 and the need to ensure existing employment land is suitably protected. The latter is crucial in attracting future investment to the region and shall act as a catalyst to enable housing to be delivered elsewhere, in more sustainable locations better connected to local services/ facilities, such as Dinas Powys.

HG1 (5) Llantwit Major - Land between the Northern Access Road and Eglwys Brewis Road (Site C – Central Parcel)
Whilst we do not oppose the overall principle of residential development at Site C (Central Parcel), this position must be considered in the context of the wider allocation. Applications for Sites A and B (2020/00351/OUT (Site A) & 2020/00352/OUT (Site B)) are currently pending subject to respective Section 106 Agreements, with prolonged negotiations resulting in significant delays to delivery. This experience clearly demonstrates that development within this allocation is complex and subject to extended viability and legal discussions, which inevitably impacts the rate at housing is able to come forward.
According to the Council’s register we understand Site C has not been subject to any formal planning application, and therefore there is no detailed evidence available regarding the proposed layout design, infrastructure requirements, viability, or anticipated submission and determination timeframes. Despite this, the Council’s housing trajectory assumes development commencing in 2028/29, with 35 units initially and 45 units annually thereafter. Given the absence of a live application and the precedent of delays on Sites A and B, these delivery assumptions appear overly optimistic based on current evidence.
On that basis we maintain that the Council should reassess the trajectory assumptions for this particular site and identify other alternatives to help account for any unforeseen slippage on Site C. The overarching purpose of which shall be to ensure the RLDP incorporates sufficient flexibility to consistently meet housing need over the entire plan period.
Policy HG3 – Housing Led Redevelopment Opportunity
Persimmon Homes acknowledges the Council’s position in respect of Site HG3 (1) – Former Eagleswell Primary School, including the temporary five-year consent (2024–2029) for 90 units of short-term accommodation and their inclusion within housing completions for monitoring purposes.
Given their expressly temporary nature and planned relocation to other sites within the Vale by 2029, it is essential that these units are not double counted in a way. As the risk of doing so would artificially inflate the Vale’s housing numbers, thereby preventing delivery opportunities elsewhere over the plan period.
Although we welcome the clarification provided at paragraph 6.111 which states that once the temporary units are removed and the site is redeveloped for permanent accommodation, any future dwellings will not be included within the RLDPs housing supply figures. In the interest of soundness, we believe this should explicitly set out within the proposed wording of Policy HG3 to avoid any potential ambiguity and thus ensure no additional net housing contributions will arise from the site upon its redevelopment later down the line.
This approach is critical given the Vale’s substantial existing landbank and the number of allocations being rolled forward, as cumulatively factoring in additional units from this site would further constrain opportunities to accommodate genuine growth elsewhere. Thereby limiting the Council’s ability to effectively meet local housing need up to 2036.
Policy SP7 – Affordable Housing Provision
In principle, Persimmon support Policy SP7’s objective to secure a minimum of 3,070 affordable homes over the plan period. That said, given the level of affordable housing is directly proportionate to the total housing provision within RLDP we believe there is scope for further uplifts in that respect.
As mentioned above Persimmon maintain that there is sufficient evidence to justify increasing the proposed housing requirements through the Vale’s flexible allowance in order to maximise opportunities for growth. In turn this would prevent artificially capping affordable housing provision at 3,070 homes to ensure the plan is positively prepared by incorporating measures that proactively address demand across the region.
National policy clearly supports this approach. Planning Policy Wales requires development plans to be positively prepared and to maximise the delivery of affordable housing as a key component of sustainable placemaking. The Development Plan Manual reinforces the need for plans to be aspirational, evidence-led and sufficiently flexible to ensure delivery. Furthermore, the Welsh Government 2025-based estimates of additional housing need report highlights the need for a step change in affordable housing delivery across Wales, recognising that continuation of past trends will not address the current affordability challenges. Collectively, this provides a clear direction of travel in that it’s imperative to uplift housing provision where affordability pressures are acute such as the Vale of Glamorgan.
To ensure the RLDP is sound, the Council should increase the overall housing requirement by apply a meaningful flexibility allowance that ensure sufficient contingency measures are in place to consistently meet local need over the plan period. This would directly increase the quantum of affordable housing secured through policy mechanisms, thereby aligning the Plan with national policy objectives. The latter goes to the heart of the tests of soundness within the Development Plan Manual in ensuring the plan is not only appropriate but capable of delivering the step change required to address affordable housing needs up to 2036.
Policy SP8 – Affordable Housing Requirements
Persimmon supports the position that residential development should help meet affordable housing need. Although to ensure Policy SP8 is effective its important the percentage requirements and site thresholds proposed are viable across a range of site types and market areas to ensure they do not inadvertently suppress delivery.
On that basis we believe it would be prudent for the Deposit Plan to clarify that affordable housing targets are subject to site-specific viability considerations and can be adjusted in circumstances where comply with such parameters would render the sites viable and thus prevent delivery. Greater flexibility is also needed in tenure and mix to better reflect evolving local needs over the entire plan period including the point when planning applications are formally submitted.
Policy SP10 – Sustainable Transport
Persimmon support the overall objective of Policy SP10 in seeking to promote sustainable transport, increase active travel opportunities and reduce reliance on the private car in accordance with national placemaking objectives. Encouraging development in accessible locations such as Dinas Powys and enhancing connectivity between settlements is welcomed. However, for soundness its important the policy recognises the different physical characteristics across the Vale of Glamorgan, particularly in edge-of-settlement and rural contexts where flexibility is necessary to ensure sustainable growth is not unduly constrained.
In this regard, the extend site at Dinas Powys represents a suitable and deliverable opportunity that aligns fully with the objectives of Policy SP10. The Authority will be aware that Transport Strategies were submitted at earlier plan-making stages, and these have now been refined through a Technical Note prepared by Vectos (now SLR) in direct response to the Candidate Sites Assessment. The scope of which confirms the proposed access arrangements presented within Policy HG1 KS2 with regards to the primary and secondary vehicular entry/ egress points on to Cardiff Road are acceptable. The former includes the creation of a new signalised junction on to the A4055/ Cardiff Road which has been modelled by Vectos (now SLR) to confirms there will be no adverse impacts with regards to the overall capacity of the local highway network. Furthermore, these measures shall be supplemented by financial contribution towards off-site improvements to help alleviate any existing connection issues/ pinch points and thus enable traffic to flow more freely within Dinas Powys and the wider surrounding area.
In addition, the scheme will deliver significant active travel benefits, including dedicated pedestrian footpaths and cycleways throughout the site that connect seamlessly into the surrounding network. The site lies within immediate walking distance of Eastbrook and Dinas Powys railway stations and therefore aligning with the Vale’s transport-orientated growth strategy. Overall, the refined Transport Strategy demonstrates that the development would not result in any significant adverse impact on the highway network, while actively promoting sustainable travel choices. Subject to proportionate application of Policy SP10 and recognition of the robust mitigation proposed, the site clearly supports and advances the sustainable transport objectives of the emerging RLDP.
Policy TR1 – Transport Proposals
Persimmon supports the overarching objectives of Policy TR1, which seeks to protect and enhance strategic transport infrastructure across the Vale of Glamorgan, including active travel routes, public transport schemes and highway improvements. Land north of Dinas Powys aligns with these objectives by directing growth to a sustainable settlement capable of supporting integrated transport solutions. The scheme has also been designed to incorporate dedicated pedestrian and cycle routes that ensures development sympathetically integrates with the surrounding area. Most notably that includes measures to enhance pedestrian permeability whilst also encouraging a shift towards more sustainable modes of travel.
In addition to the above, allocation future growth at Land North of Dinas Powys will support planned improvements between the Barry/Biglis roundabout and Dinas Powys Active Travel Route by providing on-site pedestrian and cycle infrastructure that links directly to the proposed 2 km shared walking and cycling corridor. By aligning the site layout and access points with this strategic route the scheme shall naturally maximise the route’s functionality, safety and long-term success.
Finally, the site’s highly sustainable location reinforces its accordance with the Council’s transport-led growth strategy. The development is within immediate walking distance of both Eastbrook and Dinas Powys railway stations, which provide frequent services to Cardiff and Barry other key destinations. Prioritising residential growth in such locations continues towards the Vale of Glamorgan’s aim of creating a more sustainable pattern of development, maximising the use of public transport, supporting active travel and reducing reliance on private cars.
Policy SP13 – Community Infrastructure and Planning Obligations
Persimmon Homes do not consider that Policy SP13 – Community Infrastructure and Planning Obligations is required. This is predicated on the basis that such matters are dealt with under separate legislative and policy frameworks. Therefore, as currently drafted the proposed policy (and supporting text) do not add anything further information for planning purposes and risk unnecessary duplication.
Policy CI1 – Open Space Provision
Whilst there are no comments regarding the principle, thresholds and use of the FIT standards in terms of the open space provision. As such Persimmon query the requirement for an Open Space Strategy for all sites that meet the thresholds.
The requirement within emerging Policy CI1 for applicants to prepare or submit an Open Space Strategy is not considered to be sufficiently justified or proportionate when assessed against Planning Policy Wales, which promotes access to open space and recreational provision but does not prescribe the preparation of standalone Open Space Strategies for individual planning applications. There is a lack of clarification as to what it proposed and also how the level of detail would be proportional to the size of the site.
Productive and Enterprising Places
Policy CC1 – Residential Operational Net Zero Carbon Development
Persimmon Homes, strongly object to Policy CC1 on the basis that it duplicates Welsh Government’s Future Homes Standard (FHS), which is intended to ensure all new homes are “zero-carbon ready” through a consistent national Building Regulations framework.
Building Regulations Part L currently sets the requirements for energy efficiency in new homes, with the current dwellings built by Persimmon Homes being designed to exceed the minimum requirements of Part L by incorporating enhanced insultation and improved building fabric performance. This includes low U-values for key elements such as walls, roofs, floors and windows to minimise heat loss and improve overall energy efficiency. As a result, Persimmon Homes are achieving a high rating under the Energy Performance Certificate (EPC) System, typically within the A-B range.
Introducing a separate and potentially more onerous operational net zero requirement at the local level risks imposing additional cost and complexity that undermines site viability and deliverability. The Development Plans Manual for Wales is clear that development plans must avoid repeating national policy and should not introduce requirements that are more appropriately addressed through other regulatory regimes. In this respect, Policy CC1 is not considered justified or appropriate and thereby conflicts with the second test of soundness set out within the DPM.
The proposed step change in standards from 1 April 2030 (particularly the reduction in space heating demand from 40 kWh/m²/year to 15 kWh/m²/year) represents a significant and abrupt step change in performance expectations. Whilst reference is made to initiatives such as Tai ar y Cyd and AECB CarbonLite, these have largely been associated with grant-funded affordable housing schemes. There is no clear evidence that equivalent standards are able to be delivered on mainstream housing sites without compromising their overall viability. On that note the Development Plans Manual requires policies to be underpinned by robust evidence and deliverable over the plan period. In the absence of which the proposed policy could well prevent housing delivery and undermines the emerging RLDP’s ability to effectively meet housing need.
Further to the above Policy CC1 also risks creating fragmented energy performance standards across different Local Planning Authorities in Wales. This contradicts the benefit of a consistent national approach through Building Regulations and makes it significantly more difficult for mainstream housebuilders operating across multiple authority areas to deliver homes efficiently. The DPM emphasises the need for development plans to create policy frameworks that encourage housing delivery and avoid unnecessary complications. By introducing bespoke operational monitoring requirements and energy modelling thresholds the policy as currently worded blurs the boundary between planning and Building Control functions. In turn this raises concerns as to whether the policy is justified and capable of being applied consistently across the board.
Finally, the Council’s own Viability Assessment (Paragraph 6.60 of BP42) acknowledges current uncertainty given the outcome of Welsh Government’s consultation on this topic are still unknown at the time of writing. In the event the Welsh Government decide to peruse national regulation progresses, it may be more appropriate for such matters to be addressed through Building Control rather than planning policy. Once again, this reinforces Persimmon’s concern that Policy CC1 is premature and not in general conformity with national policy. As drafted, the policy risks undermining the council’s proposed housing supply, affordable housing delivery rate and general implementation over the plan period. For these reasons, we believe it fails to meet the relevant tests of soundness and should be omitted from the proposed RLDP.
Distinctive and Natural Places
Policy SP19 – Green Infrastructure
In principle Persimmon Homes support the aim of this policy in ensuring proposed development incorporate measures that protect and enhance green infrastructure provision.
For completeness the proposed allocation (Land at north Dinas Powys) has been informed by a comprehensive Green Infrastructure Strategy and Landscape Summary Note prepared by Tir Collective (August 2023). The reports demonstrate that the site has been designed in a manner consistent with the objectives of Policy SP19. While future development of the site technically requires a release from the locally designated Green Wedge between Dinas Powys, Penarth and Llandough, the scope of which is limited in nature. Paragraph 3.70 of PPW12 states that Green Wedge boundaries should only include land that is required to remain open for the longer term. In this context, the Council’s Green Wedge Background Paper indicates that proposed allocation HG1 KS2 shall not result in any coalescence between settlements and nor does it make a significant contribution to the overall integrity of the designation. These factors confirm that the site is suitable for accommodating future residential development.
The emerging masterplan adopts a landscape-led approach that responds to the site’s physical characteristics and surrounding context. Development has therefore been excluded from the most visually sensitive parts of the site which will instead be retained as public open space to avoid having any adverse impact in that respect. This approach is reinforced through the retention and enhancement of existing hedgerows, woodland and field boundaries, alongside supplementary planting to naturally integrate the site into the wider landscape framework.
Policy SP20 – Biodiversity and Ecosystem Resilience
In principle, Persimmon support the objective of Policy SP20 which intends to protect and enhance biodiversity and ecosystem resilience. However, in the interests of soundness we believe the proposed requirement relating to biodiversity enhancement should be reframed to ensure it remains consistent with national policy. In particular, the policy should clarify that development proposals are expected to deliver biodiversity betterment in a manner that is proportionate to the scale and nature of development and consistent with national guidance. The wording should avoid introducing a requirement for a specific or quantified biodiversity net gain approach that goes beyond the national policy framework. Ensuring that the policy reflects the approach set out in Planning Policy Wales 12 will provide greater certainty for applicants and decision-makers while still providing sufficient comfort in securing the requisite biodiversity improvements.
Policy DNP1 – Special Landscape Areas
Persimmon support the revision of the Cwrt-yr-Ala Basin Special Landscape Area (SLA) to reflect the allocation of key site (HG1KS2 North of Dinas Powys off Cardiff Road) as per Policy DNP1. As indicated in Background Paper BP28 – Special Landscape Areas, the future development proposals for the site will be required to incorporate mitigation to reduce the impact of the site on the SLA. These works are incorporated into the proposed masterplan.
Policy DNP2 – Green Wedges
Persimmon support the revision to the green wedge between Dinas Powys, Penarth and Llandough, at Policy DNP2 (1) which has been amended to reflect the key site allocation HG1KS2 North of Dinas Powys.
Policy DNP8 – Severn Estuary Recreational Pressure
Policy DNP8 seeks to address recreational pressure on the Severn Estuary Special Area of Conservation, Special Protection Area and Ramsar Site. Whilst Persimmon appreciate the overarching purpose in its current form the proposed policy lacks sufficient supporting information explaining how it will operate in practice. The supporting text suggests that key details relating to mitigation delivery, including mechanisms such as Suitable Alternative Natural Greenspace and wider access management measures, will be set out in future Supplementary Planning Guidance. Deferring these important details until later down the line creates uncertainty at the plan-making stage and makes it difficult to assess whether the policy is sound, effective and/ or capable of being implemented on a consistent basis.
The policy also provides no clear threshold or criteria for determining what level of activity would constitute “visitor pressure” or an “adverse impact” on the integrity of the designated sites. Similarly, the evidence demonstrating what level of impact residents moving into new homes across the Vale of Glamorgan will generate additional recreational pressure on the Severn Estuary does not appear to have been quantified to date. While a 12.6 km recreational catchment is referenced, the supporting text does not clearly explain the evidence or methodology underpinning this distance. Moreover, the proposed text also fails to set out how new residential development will be assessed in terms of measurable impacts on the European site and thus the scope of mitigation that would subsequently be required.
From a practical standpoint this level of uncertainty is concerning given the implication of this policy are unable to be fully assessed due to the lack of evidance. For instance, if development sites within the catchment are expected to contribute financially towards mitigation measures, then the scale and mechanism of those contributions must be clearly established as part of the plan-making process. Without this clarity, there is a risk that Policy DNP8 could introduce unforeseen costs and extensive time delays, potentially affecting the viability and overall deliverability of proposed housing sites. The cumulative impact of which would then undermining the plan’s ability to meet its housing requirements and risk finding the RLDP unsound.
Conclusion
Subject to the comments within this response, Persimmon are broadly supportive of the Deposit RLDP put forward. Persimmon Homes’ most pertinent comments on the consultation document are summarised below:
• Persimmon fully supports the proposed approach to prioritise development in sustainable locations near existing rail and bus infrastructure as depicted by the strategic growth area within the RLDP Key Diagram. However, to optimise the effectiveness of this strategy growth should be focused in areas of greatest demand, such as Dinas Powys, which is not only the nearest settlement geographically to Cardiff but also inherently well connected by the existing rail network and other modes of public transport.
• Persimmon support the principle of the Settlement Hierarchy and the identification of Dinas Powys as a Primary Settlement. Whilst the importance of which is noted, Persimmon maintain that Dinas Powys, in particular, is capable of a higher role and function which can be accommodated in the extended Candidate Site Ref. No 444. This is particularly relevant given the fact that the Service Centres at Cowbridge, Llantwit Major and Penarth are generally more constrained physically and environmentally.
• Whilst Persimmon supports the overall principle of a medium growth strategy and key allocations such as North Dinas Powys. Given the Vale’s position within the Cardiff Capital Region and its designation as a national growth area, we maintain that the proposed RLDP should be more ambitious when it comes to overall housing targets. Drawing on examples from Bridgend (14% flexibility), Swansea (20%), and Monmouthshire (15%), alongside evidence of historic under-delivery and recent Welsh Government household projections, there are sufficient grounds to warrant increasing the proposed flexibility allowance to a minimum of 15%, equating to a total requirement of 9,074 homes up to 2036.
• In the interests of soundness these changes shall help account for any potential overreliance on existing landbanks and variable windfall delivery rates which could in theory limit the plan’s ability to address unmet housing need. Persimmon therefore conclude that a higher flexibility allowance and additional site allocations, such as the extended option at Dinas Powys, are necessary to ensure the RLDP is able to effectively meet local need over the plan period. The benefits of which shall also demonstrate the emerging RLDP is supported by a robust, proportionate and credible evidence base to accord with the requirements of the Development Plan Manual for Wales and national growth objectives.
• Whilst Persimmon welcome the majority of the proposed planning policies from a development management perspective. They strongly object to Policy CC1 (Residential Operational Net Zero Carbon Development) on the basis that it duplicates Welsh Government’s Future Homes Standard (FHS), which is intended to ensure all new homes are “zero-carbon ready” through a consistent national Building Regulations framework.
• Although Persimmon appreciate the overarching purpose of Policy DNP8 (Severn Estuary Recreational Pressure). In its current form the proposed policy lacks sufficient information to understand how it will operate in practice. Whilst supporting text suggests that key details relating to mitigation delivery will be set out in future Supplementary Planning Guidance. Deferring these important details until later down the line creates uncertainty at the plan-making stage and makes it difficult to assess whether the policy is sound, effective and/ or capable of being implemented on a consistent basis.
• Persimmon are wholly supportive of Land North of Dinas Powys’ (HG1 KS2) position as a proposed allocation within the emerging RLDP. The site represents a suitable, available and deliverable location for residential development without any constraints preventing it from delivering much needed homes in line with the Council’s proposed housing trajectory. Furthermore, its position as a key site is crucial to ensure growth is prioritised in such a highly sustainable location, adjacent to the defined urban area of Dinas Powys, and maximise opportunities for greater connectivity at both a regional and local level.
Persimmon would welcome the opportunity to continue on-going conversations with Officers and subsequently support the site’s progression through the next stages of the plan-making process.

Thank you for consulting Natural Resources Wales (NRW) on the Vale of Glamorgan Replacement Local Development Plan (RLDP) Deposit Plan, which we received on 28 January 2026.
We have reviewed the deposit plan and published documents and have recommendations on matters relating to coherence and consistency. We advise these are addressed prior to submission of the RLDP.
1. Summary
We welcome that the Vale of Glamorgan Council has declared a ‘nature emergency’ and in 2021 committed to a target of no net loss of biodiversity in the Vale of Glamorgan. The deposit plan takes this a step further through its vision, objectives and policies in seeking
the achievement of net biodiversity benefit. We also welcome the recognition within the deposit plan and supporting documents that additional growth within the Vale has the potential to lead to negative effects on nationally and locally designated biodiversity. We
appreciate that the deposit plan’s policies seek to mitigate against these potential adverse effects with detailed wording and requirements.
However, we consider that the deposit plan would benefit from more specific mention of designated conservation sites especially where these are related to specific allocations and their associated policies. We note this issue was raised within the Integrated Sustainability Assessment (ISA) (see Section 2 below) however we do not see this recommendation properly reflected within the deposit plan itself. We consider this is a gap that should be addressed to ensure clarity within the policy requirements for any future planning applications.
General Approach to Designated Sites
In line with our role in development planning and our consultation remit, we advise that where new development may occur within or be likely to affect statutory designated sites including Special Areas of Conservation (SAC), Special Protection Areas (SPA), Sites of Special Scientific Interest (SSSI), National Nature Reserves (NNR) and Marine Conservation Zones (MCZ) this could be more clearly identified as a key consideration especially with respect to site allocations (housing and employment). We consider that the issue of avoiding or mitigating potential impacts and utilising opportunities for supporting and enhancing these sites (as noted by para 6.401 of the deposit plan) could have more substantial recognition across the deposit plan and its supporting documents. This would improve the clarity of approach.
We have furthermore noted that Policy SP20 (Biodiversity and Ecosystem Resilience) currently excludes specific mention of designated sites (although it does refer to protected species and habitats) and we suggest that this is addressed – our comments on SP20 are set out in Section 3 of this letter.
By across the plan, we mean there is scope to include mention of relevant statutorily designated sites within the constraints text for the sites listed in Appendix B of document BP44 Infrastructure Delivery Plan (perhaps summarising in line with the approach taken to the Historic Environment Record) and within document BP32A Green Infrastructure Assessment of Key Sites, evidence which can then be reflected as appropriate in Key Sites Policies (HG1 KS1 to KS5) to inform their master planning. The Preliminary Ecological Appraisals already undertaken for Key Sites (Key Site Supporting Information) would appear to hold relevant information in this respect.
We note that document BP32A has a useful general paragraph on biodiversity assets at paras 3.7-3.8 linked to the evidence collated in the Green Infrastructure Assessment (GIA). In short, where designated sites are identified in proximity to allocated sites it would be
helpful to make clear reference to them in a consistent manner. This would bring the deposit plan more fully into alignment with the ISA findings. For any employment sites
within proximity of designated sites, we consider that the employment background paper BP12A could potentially be updated to similar effect.
With reference to omissions on this matter, we refer you to our comments on sites set out in Section 4 of this letter, including sites KS1, HG1 (1), SP14 1. and SP14 4.
Overall, we consider that the recognition of designated sites appears somewhat inconsistent in the deposit plan, although we recognise that much of this is done by the
Green Infrastructure Strategy (GIS) which incorporates the GIA.
It may be that Policy SP20 (please see our suggested amendments in Section 3 of this letter) together with addressing the meaning of “areas of high ecological value” will also go some way towards resolving the points we raise.
Master Planning
We welcome the illustrative master plans included in the deposit plan but would caveat that at the detailed stages schemes must be able to adapt, where necessary, to site
specific environmental constraints (including protected sites, species and habitats), for example in response to updated ecological appraisals or detailed species surveys.
Designs need to be flexible enough to ensure compliance with the stepwise approach (avoid, minimise, mitigate) in achieving Net Biodiversity Benefit (NBB) and improving the resilience of ecosystems as required by Planning Policy Wales, edition 12 (PPW12) and Policy 9 of Future Wales, the National Plan. We note the plan has good reference to this within Policy SP20 and supporting paragraph 6.405, thus enabling thorough consideration
at the project/planning application level and in master planning.
Please see our detailed site-specific comments in Section 4 in order to consider where our comments may lead to adjustments in master plans. For example, the species protection issues we highlight with regard to KS3 at Readers Way, Rhoose.
Strategic Opportunity at Bro Tathan
In addition to the above points, we advise that the Bro Tathan area of the Vale includes a number of different allocations and is already known as an important ecological area for great crested newts (GCN) and dormice, in particular. Given the commitments already
made under previous planning applications at the site and the necessary requirement for future biodiversity provisions, we advise a more strategic overview of the area should be considered and either set out within the deposit plan or secured within an updated GIS.
This will ensure that development in the area:
• does not cause detriment to the maintenance of the favourable conservation status of protected species;
• results in green spaces and infrastructure that is meaningfully spatially connected and sufficient in size.
Overall, we consider piecemeal development of the St Athan area will not lead to effective conservation delivery and will make the planning process less efficient at project level.
Areas of High Ecological Value
As previously noted within our preferred strategy response (Ref: CAS-244275-Q4F4, dated: 14th February 2024), the deposit plan continues to make reference to avoiding
areas of ‘High Ecological Value’ (criterion 1 of SP20). We have not been able to establish where these areas are or how their ecological value is being determined. We consider this issue needs to be clarified and ideally a definition provided.
2. Integrated Sustainability Assessment (ISA)
With regards to Section 9.9 of the ISA, we agree that additional growth in the Vale has the potential to lead to negative effects on nationally and locally designated biodiversity. The ISA concludes that the housing-specific policies set out within the deposit plan work well to
mitigate the potential adverse effects, through design stipulations and policy inclusions.
The ISA then goes on to recommend that Key Site policies are updated, where appropriate, to reference specific designated sites which they are in proximity to, in
order to help establish appropriate protection and/or enhancement measures.
We agree with these recommendations and would go further in advising that all allocations and their associated policies should reference specific designated sites relevant to that site. For instance, we would advise Barry Woodlands SSSI and Walters Farm SSSI is identified in relation to Key Site 1 – Land at North West of Barry, and Barry Woodlands SSSI should also be identified for Housing Allocation HG1 (1) Land to the West of
Pencoedtre Lane. Please refer to our site-specific comments in Section 4 below.

3. Plan and Policy Wording
Strategic Policies
Strategic Policy SP19 – Green Infrastructure
We welcome that the GIS and GIA has informed the master planning of the Key Site allocations (6.395). To ensure this approach is carried forward for other development proposals, we consider there should be a stronger “policy hook” within Policy SP19 to link the content and evidence of the GI work to the policy and its influence on decision-making. Without this we consider there may be a risk of a policy gap/mismatch when determining planning applications.
This could be resolved by a new criterion such as:
“the provision of green infrastructure must have regard to any adopted or emerging guidance including the Green Infrastructure Strategy/Green Infrastructure Assessment
(and the Assets listed therein), and Green Infrastructure (Action) Plan for the Vale.”
To strengthen Policy SP19 we also recommend an addition to the wording of criterion 2 to read:
“Protect and enhance connectivity between existing green infrastructure assets and be planned wherever possible to positively support areas of high ecological value”.
We furthermore note that criterion 3 of SP19 refers to achieving net benefit for biodiversity whilst the policy overall seeks to provide, protect and enhance high quality multi-functional green infrastructure. We have previously commented that multi-functional green spaces may not always be compatible with biodiversity. It should be recognised that multifunctional uses of space can be to the detriment of the natural environment and so must be carefully considered. We recommend that paragraph 6.397 wording is updated to reflect this potential conflict so that NBB required by PPW (and as promoted by para 6.396 together with Policy SP20) is able to be prioritised and not compromised.
This point could also be raised under Policy SP4 Placemaking – at para 6.32. It should not be assumed that multifunctional spaces will also be delivering for nature in every situation and in some cases separate provision of spaces to meet biodiversity goals will be essential.
Paragraph 6.401 is welcomed regarding the opportunities that exist for the protection, maintenance and further enhancement of green infrastructure assets.
Strategic Policy 20 (SP20) – Biodiversity and Ecosystem Resilience
We welcome the inclusion of SP20 which recognises the importance of natural assets and aims to protect these. We have made comments regarding the term “high ecological value” in our Summary section at the start of this letter.
We also note that whilst reference is made to sites and areas of European, national and local importance (para. 6.402), this is not distinctly carried through within SP20 or within a specific detailed policy in the deposit plan. We advise that a more detailed policy for the Natural Environment (similar to DNP4 for the Historic Environment) could be included within the deposit plan and this should include reference to the protection of statutorily designated sites. Alternatively, SP20 itself could be updated to include reference to these in a similar manner to the approach taken to non-statutory designated sites provided by criterion 5 of SP20. We consider this would strengthen the deposit plan’s alignment to
section 6.4.3 of PPW12. This issue is also reflected in our feedback to the ISA as set out in Section 2.
By adding a detailed policy for the wider protection of the natural environment, there is scope to ensure a clearer message within the deposit plan regarding the need for natural resources (including land, air, water and soils) in the Vale to be protected for themselves and the essential ecosystem services they deliver. This is opposed to merely preventing pollution (deposit plan Policy DNP5). Taking such an approach would enable an
opportunity to add the consideration of Sustainable Management of Natural Resources (SMNR) into the plan policy framework rather than confining this to the deposit plan context (para 2.11) and the policy context of the GIS (page 53).
We note that Policy CC4: Renewable, Low and Zero Carbon Energy Generation is more distinct in seeking to safeguard a range of assets (including nature conservation interests and soil conservation interests) and we consider a similar policy approach may be useful
for all development proposals. We also suggest that the placemaking strategic policy (Policy SP4) could be altered in order to highlight the Natural Environment alongside its
current reference to the Historic Environment. We note that placemaking principles (Figure 11 - Identity) includes the need for development to respond to natural physical attributes of the site. This is an issue is linked to our site-specific comments (Section 4 below) where we cite, for example, the need to buffer woodlands, hedgerows and watercourses and preserve linear corridors.
Ensuring an SMNR approach will impact positively on the ground to safeguard and improve ecological networks and protect and enhance ecosystems, essential to meeting
the nature emergency. Topics we draw your attention to include river restoration where, in particular, the removal/remediation of physical modifications can make a significant impact upon water quality. The GIS provides scope to capture various projects and wider initiatives, including those based on catchment scale improvements and we welcome the opportunity to be continually involved in this work. We note and welcome the recognition of
nature-based solutions within Policies SP16, SP19 and SP20 and in detailed Policy CC6.
With regards to natural assets and water resources, we consider that specific reference to water quality is lacking within the strategic and/or detailed policies. Whilst we note that water quality is mentioned within criterion 9 of Policy SP16, we consider the deposit plan should include more direct reference to the Water Framework Directive. We consider there is an opportunity for SP20 to be updated to ensure developments protect water quality and quantity. Alternatively, as mentioned above, this could fit within a detailed policy for the protection of the natural environment.
As a minor point, please note that the South Central Area Statement is not hyphenated (para 2.10 and 2.11). Please note also that, referring to paragraph 6.404 and 6.405, the
requirements for developments to demonstrate NBB is based on PPW12, rather than The Environment (Wales) Act 2016.

Detailed Policies

Infrastructure
Whilst we note that the infrastructure requirements (such as sewerage capacity) have been investigated for certain key sites within the deposit plan, we consider there could be scope for a detailed policy to cover infrastructure requirements for all development.

Policy DNP7
We welcome Policy DNP7 of the deposit plan, which recognises the importance of preserving the natural darkness of the night sky and minimising light pollution, which we consider to be important in limiting adverse impacts upon local biodiversity and ecological
connectivity.

Policy DPN8
Please refer to comments made with regards to this policy under Section 6: Habitats Regulation Assessment (HRA).

Policy HG5 - Affordable Housing Exception Sites
We advise that, particularly given these sites are permissible outside of settlements and could be in countryside locations, criterion 6 should be amended to:
“There is no loss of land with significant recreational, amenity, agricultural, ecological or natural heritage value”.

EMP1 – Employment Regeneration Opportunity Areas
We note that the Former Aberthaw Power Station has been identified as an employment regeneration opportunity area. There are otter and water vole records on the site and we are aware of GCN records within the local area. We would advise against the inclusion of
the Aberthaw Nature Reserve within the allocation and advise that any application on the site would need to be supported by up-to-date ecological survey information and
appropriate conservation measures. Given the nature of the site, future applications will also need to be supported by appropriate land contamination investigations.

CC3 – Renewable Energy Local Search Areas
This policy identifies several sites where the potential for wind and solar development are the greatest (known as ‘search areas’). There are significant search areas located between Llantrithyd and St Hilary; no ecological information has been provided for these search areas, however given the records for GCN, water vole and otter local to these areas, it is likely that provision in the form of suitable habitats will need to be made for these species.
This could be substantial in scale, however without further ecological information we cannot advise further at this time. Notwithstanding, given the scale of the search area in this location and the likely ecological impacts, we advise that this area would benefit from spatial planning of biodiversity provision, at a greater than individual site scale.

Paragraph 2.81 – The Vale Nature Recovery Action Plan
We note reference to ‘6 broad habitat types’ including Woodland, Freshwater, Grassland, Coastal, Agriculture and Urban. We suggest this is amended to ‘6 broad ecosystems’ to reflect correct terminology and the State of Natural Resources Report 2025.

4. Strategic Sites
Overview
We previously provided detailed comments on the RLDP’s Strategic Sites, as set out in our response ref: CAS-234819-C1V3, dated 4th October 2023, which we refer you to. We welcome the additional information provided and note the inclusion of Green Infrastructure
Strategies for each of the Key Sites. However, we note that these do not include reference to protected species specifically and as a result we are unable to confirm that the provision for each site is appropriate. We observe that the road infrastructure for many of these sites severs woodlands and other substantial linear corridors. We advise that such sites are designed to minimise fragmentation in the landscape and advise that the road layouts and consequent severance is re-visited.

KS4 and KS5 are located within the vicinity of St Athan. This area is important for (and we are aware of) multiple records of GCN and dormice. Some of the area is already secured as compensation for impacts on these species associated with previous developments. We advise that the wider St Athan area is subject to spatial planning of biodiversity provision at a greater than individual site scale (as we have referenced in the Section 1 of this letter), in order to determine that:
• It does not cause detriment to the maintenance of the favourable conservation status of both GCN and dormice (strategic conservation plans should be established for both species);
• To ensure that green spaces and infrastructure are meaningfully spatially connected and sufficient in size;
We consider piecemeal development of these areas will not lead to effective conservation delivery and will cause the delivery of these sites to be less effective during the planning process.

Spatial Planning of Biodiversity
A masterplan or spatial biodiversity or GI plan should demonstrate the retention, provision and enhancement of essential areas for protected species. It should ensure that individual site-based habitat provisions are not designed in isolation but considered in association with nearby sites to demonstrate how habitat connectivity and resilience will be provided both across the site and to the wider landscape. Note that functional separation of public
open space and areas for biodiversity compensation may be required. Suitable buffers will need to be applied to any woodland and retained or created habitats on site. A sensitive lighting strategy will also likely be required for these sites. This point was raised previously during our review of the strategic candidate sites (ref: CAS-234819-C1V3, dated 4th October 2023).

Updated Surveys and Appropriate Buffer Zones
Further to the above comments, we welcome reference within the Infrastructure Delivery Plan for the requirement for updated ecological surveys and appropriate buffer zones to watercourses and retained habitat features for KS1 and KS2. Given the various ecological
constraints for each key site, we consider this advice should be included for each of the key sites.

Site Specific Comments
KS1 – Land at North West Barry
Protected Species – Dormice and bats are present on site. We advise that the masterplan is informed by surveys to ensure that biodiversity interests are maintained and enhanced. The site may require some areas to be retained an/or provision for habitats to support them. Dark areas and/or bespoke lighting scheme may also be required at project stage.
Protected Sites – The site is located in close proximity to Walters Farm and Barry Woodlands SSSI. As raised in our previous responses (CAS-234819-C1V3, dated: 4th
October 2023 and CAS-276923-N7H6, dated 17th April 2025), we have some concerns with the potential for increased and inappropriate use of the protected sites through recreational activities. We welcome that requirements have been detailed within HG1 KS1
under Green Infrastructure, Recreation Spaces and Biodiversity, which includes reference to emerging guidance for Suitable Alternate Natural Greenspace (SANG).

KS2 – North of Dinas Powys, off Cardiff Road
Protected Species – We note the supporting Preliminary Ecological Appraisal (PEA) (13th September 2022) which identifies potential for this site to support GCN, dormouse and bats. In the absence of species specific surveys, we are unable to advise whether the housing number aspirations for the site are realistic. We advise the scheme is designed to minimise severance of ecological corridors.

KS3 – Land at Readers Way
Protected Species – GCN are known to be present on this site (Readers Way Pond). The current masterplan indicates that the pond will be surrounded by built development and therefore built upon much of the terrestrial habitat which supports this pond. It is essential
that the masterplan provides a wide corridor from this pond to the wider countryside, other than via the closely managed grassland at Cardiff Airport. Any masterplan should make provision for this and any loss of habitat should be compensated for.

KS4 – Land at Church Farm
Protected Species - There are records of dormouse and GCN in the wider area. However, the supporting PEA indicates no direct impacts on the latter of the species. There appears to be extensive green space proposed in the illustrative masterplan, which we support.

KS5 – Land to the West of St Athan
Protected Species - The St Athan area is important area for GCN and dormouse. We would generally concur with the lower risk assessed for these species in association with this site. However, this is a substantial site and this and other sites in the St Athan area would benefit from spatial planning of biodiversity provision at a greater scale as reaffirmed elsewhere in this response.

5. Housing And Employment Allocations
Housing Allocations

HG1 (1) Land to the West of Pencoedtre Lane
Protected Sites: The site is within close proximity (200m) to Barry Woodlands Site of Special Scientific Interest (SSSI) and there is a risk from increased recreational use as a result of residential development, which could lead to impacts on the SSSI. Green space design must consider any emerging guidance for SANG to reduce recreational pressure on adjacent sites of biodiversity importance.
HG1 (2) Land at the Mole
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary European Marine Site (EMS). A HRA at project level will therefore be required.

HG1 (3) Land at Hayes Lane
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

HG1 (4) Land at Neptune Road
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

HG1 (5) Land between the Northern Access Road and Eglwys Brewis Road (Site C - Central Parcel)
Flood Risk: The site is located partially within Flood Zone 2 and 3 for Rivers, with the southern area of the site located within Flood Zone 3. We refer you to Sections 10.20 and 10.21 of TAN 15, which state that highly vulnerable development in Zone 3 should be avoided. Notwithstanding, we acknowledge that at masterplanning stage, there is scope to locate residential development away from areas of flood risk. We also welcome that
Appendix B of your Infrastructure Delivery Plan notes the requirement for an FCA at project level for this site.
Watercourse: Boverton Brook (Main River) runs through the site and any development will need to ensure no adverse impacts to the watercourse with appropriate buffers and design considerations.

HG1 (6) Land adjoining St Athan Road
Land Contamination: The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.

Rural Affordable Housing Led Sites
HG4 (1) Land to the East of Colwinston
Land Contamination: The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.

Major Employment Allocations
SP14 (1) Land east of Cardiff Airport, Rhoose
Protected Species and Protected Sites: The site is within close proximity (360m) of Barry Woodlands SSSI and there also appears to be significant potential for the site to support dormouse, GCN, otter and water vole. There are large areas of semi-natural habitats associated with this site including woodland, mature hedgerow and watercourses. These should be retained and significantly buffered from development. Connectivity between the
site and the wider environment should also be maintained. It is therefore currently not possible to advise whether the full aspirations of the site could be fulfilled.
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (2) Land south of Port Road (Model Farm), Rhoose
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (3) Bro Tathan Aerospace and Business Park
Protected Species: The site is located within an important area for GCN and dormice. As mentioned, this area would benefit from spatial planning of biodiversity provision at a
greater scale to better inform allocation.
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (4) Land to the South of Junction 34 of the M4, Hensol
Protected Sites: The site is located directly adjacent to Ely Valley SSSI. Given the biodiversity interest at the site, previous applications at the site include planning
commitments to conserve and enhance grasslands habitats on the site. These commitments have not yet materialised and the requirement for these provisions should be noted within the LDP.
Flood Risk: The site is located partially within Flood Zone 3 for Sea. We advise that an FCA will be required at project level to determine any flood risk implications at the site.

Local Employment Allocations
SP14 (5) Atlantic Trading Estate, Barry
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination. The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

SP14 (6) Windmill Park, Hayes Road, Barry
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination. The site is located over a principal aquifer. Any development would need to consider the hydrological setting of the site and vulnerability of pollution.
Flood Risk: The site is located partially within Flood Zone 3 for Sea. We advise that an FCA will be required at project level to determine any flood risk implications at the site.
Marine: An adjacent watercourse forms a hydrological link to the Severn Estuary EMS. A HRA at project level will therefore be required.

SP14 (7) Vale Business Park, Llandow
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

SP14 (8) Land at Llandow Trading Estate
Land Contamination: Given previous land use at site, a Preliminary Risk Assessment would be required at planning application stage to determine risk of land contamination.

6. Habitats Regulations Assessment (HRA)
Marine and Coastal Physical Processes
Coastal Squeeze
We note that coastal squeeze has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is that it “is unlikely that the Vale of Glamorgan RLDP will allocate many developments on
greenfield sites adjoining the estuary”.
We also note that Policy CC6 specifically relates to Coastal Defences and Shoreline Management, with reference to the Shoreline Management Plans. We recommend the use of NRW’s Assessment of Coastal Squeeze at the project level for anyone proposing to
undertake works to coastal structures.

Loss of Functionally Linked Habitat
As part of the Preferred Strategy consultation, we advised that consideration was given to potential impacts on migratory fish features of the Severn Estuary EMS. In particular, we referenced the River Ely and its tributaries providing supporting habitat for essential life cycle processes of some or all the diadromous fish species.
Within the deposit plan HRA, it is noted that likely significant effects to the migratory fish features of the Severn Estuary EMS has been ruled out, as none of the sites allocated in the RLDP lie in close proximity to the River Ely and connected watercourses. We therefore
agree with this conclusion.
In relation to bird features, Table 8 of the Appropriate Assessment identifies many key sites and allocations with high to medium potential for functional linkage to the Severn Estuary EMS. We note that loss of functionally linked habitat has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is the inclusion of ‘Policy DNP8 – Severn Estuary Recreational
Pressure’ within the deposit plan.

Policy DNP8
We advise that clarification is needed in relation to this policy, as while we welcome the supporting text regarding functionally linked land outlined in paragraph 6.76 of the HRA, the policy is mainly focused on recreational pressure and is titled as such. We also note a discrepancy between the policy wording in paragraph 6.76 and Policy DNP8 in the deposit plan itself.

Visual and Noise Disturbance (During Construction)
Within the deposit plan HRA, visual and noise disturbance has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. The justification for this is through the inclusion of recommendations outlined in 6.83 of the HRA to the supporting text of Policy SP20, which we welcome.
We also welcome the recommendation in relation to potential functionally linked land as outlined in paragraph 6.84 of the HRA.

Recreational Pressure
Within the deposit plan HRA, recreational pressure has been screened in and taken through to Appropriate Assessment where a conclusion of no adverse effect was reached. Again, the justification for this is the inclusion of ‘Policy DNP8 – Severn Estuary Recreational Pressure’ within the deposit plan, which as above, we advise needs
clarification.
We note that no visitor data has been collected from access points within the Vale of Glamorgan, but we welcome reference to the visitor surveys undertaken by
Monmouthshire and Torfaen, as well as the 2022 visitor survey commissioned by Stroud District Council.
We note that paragraph 6.25 of the HRA states that “three Key Sites and several other housing allocations lie within the 12.6km core recreational catchment that has been
deemed most appropriate for the Severn Estuary SAC/SPA/Ramsar”. However, we also note that Table 6 in the HRA only includes two Key Sites requiring mitigation, with KS3 being omitted. We advise that clarification is needed at the project level as to whether developments are situated within the 12.6km catchment area.

7. Strategic Flood Consequence Assessment (SFCA)
We have reviewed the submitted SFCA and agree with the scope of the assessment made.
We note there is currently an upper catchment Natural Flood Management (NFM) / Nature Based Solutions (NbS) project on the Cadoxton to reduce flood risk to Dinas Powys, Any updated SCFA should have regard to NFM schemes being progressed in their area and
proposals should be clearly outlined in the Development Plan (in accordance with TAN 15 2025).

8. Green Infrastructure Strategy (GIS)
We understand that the published GIS has not been updated to reflect the latest stage of the deposit plan and refers only to the preferred strategy stage (para 2.2.3). We previously provided advice on the Green Infrastructure Assessment (GIA) (re: CAS-252087-F0H1, dated 14th May 2024) which is included within the GIS. We refer you to these comments, noting that the GIS will be kept under continual review (para 1.2.5).

Strong support is expressed for the proposed allocation at Land north of Westwinds, Fferm Goch of rural affordable-led housing within the Vale of Glamorgan Draft Local Development Plan (LDP) under policy HG4(4).
As part of our comments to the above policy consideration must be attributed to viability on a site specific basis. Furthermore, questions are raised over whether sufficient affordable dwellings are proposed to 2036 in the Vale given current trends and forecasts.

The inclusion of the site within the settlement boundary is logical especially when viewed in the context of the linear settlement of Fferm Goch. In addition the site is further suited to development allocation as the northern and southern boundaries are built up and the main road runs along the eastern boundary. A flexible approach is encouraged with regard to the delivery of the dwellings in relation to a variety of factors and policy provisions including the housing needs across the Vale, the limit on numbers of rural affordable led sites in minor rural settlements, viability implications relating to obligations/carbon Zero and sustainability obligations and the potential to extend the allocation if the need for homes requires.

The 3 land owners remain committed to this development and local developers are waiting to deliver the allocation.

In summary the extension to the settlement boundary of Fferm Goch, to include the allocation HG4(4) is supported. The attached representation is made under the following policies:
• Policy SP1 – Sustainable Growth Strategy
• Policy SP2 – Settlement Hierarchy
• Policy PGD2 – Residential Development Densities
• Policy SP6 – Housing Requirement
• Policy SP7 – Affordable housing provision
• Policy SP8 – Affordable housing requirements
• Policy HG4 – Rural Affordable Housing Sites
• Policy SP13 – Community Infrastructure and planning obligations
• Policy CI1 – Open space provision
• Policy SP16 – Climate change mitigation and adaptation
• Policy DNP1 – Special landscape Areas

The test of soundness for a Local Development Plan (LDP) is a critical component of the planning process to ensure that the plan is prepared in accordance with legal and procedural
requirements. It involves demonstrating that the plan is 'sound' based on three tests set out by the Welsh Government in the Development Plans Manual (Edition 3). These tests have therefore been considered in our representation, the tests include:

• Test 1: Does the plan fit? (i.e. is it clear that the LDP is consistent with other plans?)
• Test 2: Is the plan appropriate? (i.e. is the plan appropriate for the area in the light of the evidence?)
• Test 3: Will the plan deliver (i.e. is it likely to be effective?)

SP1 – Sustainable Growth Strategy

The promotion of small scale affordable housing led development outside of the SGA, as proposed by SP1 is important as this provides essential affordable and market homes in the rural locations of the Vale as well as the SGA. Their provision is critical in meeting the area’s housing needs, particularly affordable dwellings and supporting rural community stability, and ensuring that all parts of the Vale remain a place where people of all incomes are able to live and thrive during the plan period to 2036 and beyond.

The essence of Policy SP1 is supported, however it is well documented that there is a backlog in delivery of affordable homes and the need for affordable housing in the Vale is exacerbated by the high prevalence of single person households plus households comprising couples with no children, The Vale also has one of the highest affordability pressures in Wales. As stated in the 2023 Local Housing Market Assessment (LHMA) for the Vale of Glamorgan , the median house price in the Vale is around 8 times the median household income, well above the affordability threshold of 4.5 to 5 times household income for borrowing purposes. Private rents have also risen sharply in the area, commonly placing them out of reach for many low-to-middle income households. All of the above place further pressure on the need to deliver affordable homes in the locality.

The LHMA identifies a need for 1,075 affordable homes per year over the next 5 years based on principal projections (or 1,114 based on the RLDP projections). As mentioned previously past delivery rates fall significantly short and therefore a backlog is present, however despite the reported backlog the RLDP only proposes 3,070 (205/annum) affordable dwellings over the plan period to 2036. Despite the growth strategy of policy SP1 and allocations made through the RLDP, the figure of proposed affordable dwelling numbers is concerning as it falls significantly short of the demand evidenced within the most recent evidence of LHMA of 2023.

The housing figures quoted in SP1 indicate 7,890 dwellings ( including the 3,070 affordable dwellings) to 2036, however these figures overall are inadequate over the plan period when considered against the 2022 WG household projections. The 2022-based household projections provide an indication of the future number of households, and their composition, based on population projections and assumptions about households from recent censuses. The vale of Glamorgan demonstrates an increase of almost 12% in the number of households between mid-2022 and mid-2032; note this is the highest percentage increase by Local authority in Wales and way above the average for Wales as a whole (that stands at around 7% increase). The concern is whether Policy SP1 goes far enough in providing for the scale of housing ( both open market, but particularly Affordable) development across the Vale.

Without targeted allocations outside of the SGA, as outlined in Policy SP1, the gap described above will continue to widen, forcing more residents to leave the area and weakening community cohesion.

SP2 – Settlement Hierarchy

Policy SP2 states a range of rural settlements are categorised as ‘Minor Rural Settlements’. Within the
RLDP the supporting text of Policy SP2 states:
‘several of the smaller rural settlements such as Colwinston, St Nicholas and Fferm Goch include primary schools that serve a wider catchment area, whilst others also provide small scale local employment opportunities, either within or near the settlements. Due to these functional links between rural settlements, it is essential to ensure that existing services and facilities are safeguarded, supported, or enhanced where appropriate’.(Paragraph 6.16)
Fferm Goch is categorised as a Minor rural settlement within the Settlement hierarchy and given its size and range of facilities/services this is supported. It is noted however that both Fferm Goch and Colwinston are identified as serving a wider catchment due to the provision of their primary schools. The allocation of HG4 site at Fferm Goch will further support and sustain the following:
• The Llangan primary school that sits in the southern portion of the settlement boundary.
• The existing employment site of WestWinds Business Park.
• The community hall (Llangan and St Mary Hill Village Hall) to the north of the settlement.
These existing services and facilities should be supported and sustained through the new housing allocation (HG4(4) in the immediate locality. This allocation supports the Vale’s own strategic objectives for

sustainable growth. Locating affordable-led developments in areas with existing infrastructure such as primary schools will reduce car dependency, lower carbon emissions, and contribute to the Council’s climate change commitments.

Considering the above, the limit on small scale rural affordable housing led developments (RAHLD) to 25 for these settlements is questioned and further flexibility recommended on a case by case basis. It is understood the limit on numbers was imposed due to the existing scale of the settlement in which the RAHLD are located, however those allocations will only likely deliver at 50% affordable and therefore only provide 12.5 ( or 13) affordable units as a maximum (note Fferm Goch would provide 11 affordable dwellings on current figures of 22 total dwellings). Given the concerns raised in response to Policy SP1 there remains an issue of whether the numbers proposed in the RLDP can meet the demonstrable need for affordable homes and if there is scope on a RAHLD to sensitively increase unit numbers without any material harm then the policy should be flexible to accommodate this.

Wick and Culverhouse Cross have been elevated to Primary Settlements outside the SGA; this is supported given the range of facilities and services provided in these settlements. It is also supported that these settlements are able to provide affordable led residential development of up to 50 dwellings ( delivering 25 affordable units). However the provision of an increased number of units in the Primary Non SGA settlements must not be at the expense of a wider number of smaller rural sites with the ability to sustain smaller communities across the Vale, especially given the shortfall in numbers as outlined above.

PGD2 – Residential Development Densities

The best use of finite land is set out in PPW and consistent with the setting of the densities as prescribed in policy PGD2. The policy is considered to meet the 3 tests of soundness.

The approach of policy PGD2 is also supported through the proposed density of the site North of Westwinds business park, Fferm Goch in HG4 (4). This allocation that proposes to provide a density of just over 30/ha within Fferm Goch, a minor rural settlement.

SP6 – Housing Requirement

Affordable housing forms an important part of the housing requirement figures of Policy SP6. Whilst the total 122 dwellings proposed under policy HG4 is a relatively small contribution to the overall figures it provides important spatial distribution of homes across the Vale within the rural area.

Given the concerns raised with regard to Policy SP1 there is fear that the affordable housing numbers will not be sufficient to meet need. The site north of Westwinds business park, Fferm Goch has the ability to expand to the south (as per the CS Ref 398) in order to accommodate additional dwellings (both market and affordable dwellings in order to sustain the viability of the site).

SP7 – Affordable Housing Provision

In accordance with Policy SP7 the allocated site HG4(4) at Fferm Goch provides a range of tenures, types and sizes in response to the LHMA, waiting list data and Older persons housing strategy in order to provide for 11 dwelling units and contributing toward the 3,070 affordable requirement to 2036. Changes in the household composition mean more single person and small homes are required, plus older person accommodation for those wishing to downsize and stay in the area.

Please see comments for Policy SP1 / Policy SP2 above regards concern over the proposed housing numbers and supply of affordable homes against demand - this therefore brings the Deliverability of the plan in to question (Test of Soundness 3).

SP8 – Affordable Housing Requirements

Policy SP8 is supported in so far as contributing much needed affordable housing development commensurate with the size of the settlement in which it sits. We are encourage to see reference to the provision of affordable housing to be negotiated on a site by site basis considering evidenced viability fo the development.

The affordable dwellings proposed foster stability in rural areas by allowing a range of households (from single person to growing families) to stay in their local area.

Policy SP8 states 40% affordable for those developments in primary and minor settlements outside of the SGA yet 50% requirement on affordable housing led allocations in minor rural settlements ( also outside of the SGA). This appears inconsistent and penalising those smaller rural sites that will already be more delicately balanced in viability terms by virtue of their limited size of 25 units. Further viability issues covered in other policies ( such as SP20, relating to biodiversity, Net Zero and sustainability credentials must (with the required evidence submitted and assessed by the council as stated in Policy SP8) be flexibly reviewed to ensure sites are viable and deliverable as recognised by the Council, there is a danger the stringent requirements, especially for smaller sites, could render those sites unviable in the current climate with rising build costs.

HG4 – Rural affordable housing led sites

The allocation of land north of West Winds Business Park under policy HG4(4) for rural affordable housing led development of 22 units is strongly supported. Then allocation will assist in delivering homes in the rural Vale and contribute to the important stability to the settlement of Fferm Goch to 2036.

The extension of the settlement limit including the site north of West Winds Business Park is supported. The site provides an obvious infill to the small break in the built up area to both the north and south of the site, with the main road running to the eastern boundary of the site.

The inclusion of the site within the settlement of Fferm Goch is logical and in harmony with the existing linear settlement.

The proposal supports the aims of the Local Development Plan and the Welsh Government’s commitment to increasing affordable housing supply. By providing for affordable led allocations the policy aligns with the Well-being of Future Generations (Wales) Act 2015 in aiming to promote a healthier, more equal, and cohesive community.

There is concern however surrounding the number of dwellings proposed and if the Plan seeks sufficient dwellings and affordable provision given the predicted need to 2036 shown in the LMHA.

SP13 – Community infrastructure and planning obligations

Policy SP13 demonstrates the importance of community infrastructure in sustaining both the residents well being and economic growth of an area. See also the response to Policy SP2 that refers to the allocation of housing in the rural areas specifically supporting those settlements with local primary school provision.

The viability of developments however must not be compromised in order to ensure delivery of the plan. To see in Policy SP13 that ‘development viability’ is recognised as a key factor in delivering community infrastructure under planning obligations, is supported. It is recommended that this recognition is replicated in other policies of the LDP in order that the third Test of soundness can be fully met; Deliverability – ensuring the plan is likely to be effective). See comments in relation to Policies SP8/CC1/SP16/CI1.

CI1 – Open Space Provision

Provision of open space in residential developments is supported. HG4(4) promotes open space within the draft allocation.

The viability of developments however must not be compromised in order to ensure delivery of the plan. The ‘development viability’ should recognised as a key factor in delivering open space ( see comments on SP13 / SP8 where evidenced viability is specifically referenced within those policies – this approach is supported.

SP16 - Climate change Mitigation and Adaptation

The provisions of SP16 are generally supported as practical measures to ensure important sustainable development is achieved.

CC1 – Residential Operational Net Zero Carbon Development

The provisions of Policy CC1 echo the WG targets for Net Zero by 2050.
Whilst some of the supporting text to policy CC1 references viability, the ultimate viability of developments however must not be compromised in order to ensure delivery of the plan. The technical feasibility of renewable energy regeneration is referenced in the above policy however the ‘development viability’ should also be included. See comments on SP13 / SP8 where evidenced viability is specifically referenced within those policies – this approach is supported.

SP19 – Green Infrastructure

Provision of Green Infrastructure in residential, and all developments is supported.

HG4(4) retains and enhances existing and will promote green infrastructure on the draft allocation.

The viability of developments however must not be compromised through green infrastructure provision - in order to ensure delivery of the plan. The ‘development viability’ should therefore be recognised as a key factor in delivering Green Infrastructure. See comments on SP13 / SP8 where evidenced viability is specifically referenced within those policies – this approach is supported.

SP20 – Biodiversity and Ecosystem resilience

The above Policy is in accordance with Chapter 6 PPW. The approach is supported and dovetails with SP19 above.

DNP1 – Special Landscape Areas

DNP1 identified Special Landscape Areas across the Vale.

Fferm Goch is one of the settlements that remains fully within and covered by the Upper and Lower Thaw Valley Special Landscape Area (SLA). It is noted that in such settlements, while there have been amendments to the identified settlement boundary ( inclusion of HG4 (4) rural affordable led housing allocation) this has not affected the SLA designation in these areas. (Background Paper 45; Paragraph 1.16 refers).

The location of the small allocated site HG4(4) is nestled within the settlement of Fferm Goch. It is built up on both the northern and southern boundaries, with the main road running along the eastern boundary. There is no unacceptable harm to the SLA of the Upper and Lower Thaw valley.

The allocation of the site for residential development does not give rise to unacceptable harm to the special qualities and characteristics of the SLA, based on LANDMAP information, continues to be preserved.
