There is obvioulsy a lot more work that needs to be done after the consulation closes but one specific stands out for me. In the RLDP there is acknowledgement that there is a need for a Flood Alleviation Scheme for Llanmaes. This is commented on more than once but there are no specific proposals or any outline as to how any proposals or actions will come into being on this point.

Crynodeb o'r Gynrychiolaeth:

The statutory Section 19 report on the 23 Dec2020 flooding of about 100 properties included recommendations that have been ignored, relating to blockage during high river levels of highway drains from central streets and of the Cae'r Odyn's newer street drains.

The Strategic Flood Consequences Assessment omits mention of that flood episode (1:20yr rainstorm) and omits mention of the need for measures to cope with stronger rainstorms(1:100). We guess that omission was not due to the consultant JPA who has professional standards to maintain, but to the LPA or RLDP team. Whichever, it fails to comply with
3.4 The SFCA is a desk-based study which collates existing information to undertake a broad assessment of potential flood risks across the study area, including the Vale of Glamorgan, from all sources of flooding. The study identifies areas at potential high risk from flooding, provides details of historical flood events, and detail of any flood risk management structures or procedures present.
The SFCA fails to mention the Dec.2020 flooding, the 2021 Section 19 report on it with unfulfilled recommendations and NRW’s conclusion from ~2018 to not proceed with dam/holding reservoir upstream but “working with nature” with catchment measures. JPA Consulting wrote both the Section 19 report and this SFCA. It’s likely not JPA but the RLDP team omitted this important information, because of their interest in promoting the site for housing. Whichever, the SFCA is a statutory document that requires completing to professional standard.

The SFCA does identify priority areas for natural flood management. In this regard, the SFCA (9.3.6.10) identifies small areas across the Vale that are suitable for runoff attenuation and large portions of the Vale that are suitable for wider catchment woodland planting… (Appendix J1 of the SFCA). We find a map on p.153 Working with Natural Processes - Potential Mapping (JPA + VoG Dec.2021) show Woodland Planting on this hillside, including part of the Persimmon site.

The fields below Llandough Hospital are an important part of the East Brook catchment. Drainage from the Hospital discharging into the East Brook (via settlement tanks) increased over the last decade by large area carparking and building developments.

The development site and adjacent hillside fields are a significant holding area for rainstorms, soakaway being slow. Housing development with normal SuDS measures with “attenuation ponds” will speed up storm-discharges. The issue is not as the KS2 spec says Small area <5% affected by river flooding, but the the downstream consequencies of the development in flooding at the Murch cross-road and adding to the river Cadoxton just downstream.

The applicant has no given any study to include measures to trap the stormwater in holding ponds, or otherwise to increase delays to it reaching the East Brook. He has concealed the proposal for woodland planting on part of the site as the SFCA map indicates.

The strong flooding constraint is also being hidden by the RLDP people, if it’s they who have censored important material from the JPA report.

We require a revised statutory SFCA is issued to professional standard which properly includes both the 2021 Section 19 report and proposals for forward policy towards flooding measures for Dinas Powys itself. These would be oriented to “working with nature” as agreed, and recognize that the Eastbrook housing development goes in the wrong direction. They would also record the need to divert highway drainage from discharges into the Cadoxton as per the Section 19 recommendations.

Testun llawn:

Safeguarding against flooding has to be the priority for any development in Dinas Powys. The strategic Flood Assessment report's omission of setting such a requirement is unacceptable. The Section 19 report on the 23 Dec2020 flooding of about 100 properties produced recommendations that have been ignored, relating to blockage during high river levels of highway drains from central streets and of the Cae'r Odyn's newer street drains. The omission of that flood episode (1:20yr rainstorm) and reporting need for measures to cope with stronger rainstorms(1:100) seems not due to the consultant JPA but to the LPA or RLDP team.

The deferred flood alleviation scheme for Llanmaes affected our land in Siginstone lane. The RLDP mentions this scheme several times but no response has been forth coming. The village floods and for many many years. The council and the Welsh government have put in funding to solve this but nothing has yet happened. Indeed in the RLDP it is mentioned extensively that the village floods but we cannot see what specific directions have been made to resolve this problem. I urge the Vale council to liaise with the Welsh government about bringing this forward and mention in the deposit plan.
I appreciate that the costs of the plan increased substantially with the fuel costs of the Ukraine war and probable is increasing again. However, parts of the plan, reprofiling the road and channeling flood water away from housing could have made a difference without the extensive earth works in fields referred too above. If my suggestion of extensive tree planting in above fields instead of bunds and channels had been implemented the risks may already be reduced.

I attended the consultation at CF61 about the RLDP and was advised to write to you with my comments.

I was pleased to see that in the RLDP that the fields adjacent to the LLantwit Major Bypass (site ID 436 Proposal number DN2(6) is designated as a Green wedge That application was made by our Community council and I fully support this proposal. the reasons they gave and I agree with this , are that protection of the open country side, protects against the coalescence of the town and our rural village, and protects the setting of the conservation area.



I see that the Planning policy has ring fenced the location of the proposed Lidl development (ID 379 Proposal number SP12(2) that is currently called in by the Welsh government . You will be aware that the Planning committee voted against the recommendation of the planning officer. when they made there decision, that is now being challenged as procedurally against a lot of Vale and Welsh Government policies. Looking forward to this site being included in the green wedge when this ridicules decision is over turned

I note with interest that several fields to the north east of Llanmaes have been designated as potential solar farm sites. These very fields are partially responsible for the flooding risk in Llanmaes. I suspect that solar farms would not help this problem.

The deferred flood alleviation scheme for Llanmaes affected our land in Siginstone lane. The RLDP mentions this scheme several times but no response has been forth coming. The village floods and for many many years The council and the Welsh government have put in funding in 2023, the Welsh government allocated £3,090,855 and in 24/25 £16,000 to solve this. Nothing has yet happened, indeed in the RLDP it is mentioned extensively that the village floods but we cannot see what specific directions have been made to resolve this problem. I urge the Vale council to liaise with the Welsh government about bringing this forward and mention in the deposit plan.

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).

Testun llawn:

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.

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.

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).

Flood Alleviation
The need for a flood alleviation scheme for Llanmaes is acknowledged on several occasions in the Deposit Plan , thugh unfortunately there are no specific proposals. Having lived in Llanmaes for 7 years, I have whitnessed regular flooding from surface water over the wetter months when the village stream and drains are unable to cope with the volume of water. This water then overwhelms the sewage system in the village resulting in raw sewage flooding a number of homes as well as the village playing field . This flooding also results in road flooding in at least 3 places around the village lanes. This has become an annual occurance, and despite intervention from Welsh Water , the situation has not been resolved. A Welsh Government grant for an alleviation scheme has to date not been implimented and this scheme needs to be revived for the safety of the village residents.

Retail - Land at Bridge House Farm Site ID 379 Proposal Number SP12(2)
In 2022 LIDL submitted a planning application for a supermarket on a parcel of land which had in the past been part of Bridge House Farm. The farmhiuse itself had stood vacant for a number of years until it was recently purchased and is being restored as a family home.
The application attracted a great dea of concern and objetions based on the fact that this development would result in both visual and physical coalescence between Llanmaes and Llantwit Major. Its entrance would be directly off the main access lane to Llanmaes, close to the main road junction,managed by traffic lights and pedestrian crossing.
The planners at the Vale of Glamorgan recommended refusal of this application based on the the fact that the site was outside the RLDP's defined strategic growth area and other associated concerns. However at the planning meeting, a small number of Councillors argued in favour of the development , based on the need for ' cheap food', and as such the application was approved. Since this meeting , the application has been referred to PEDW, and their initial assessment that an appeal should be heard, the application has been escalated to a full enquiry at great expense to all parties. This ' cheap food 'option not quite such a special offer after all.
In order to overcome the sitution that this overturning of the planners' recommendation has created, a simple remedy would be for the Welsh Government to offer an alternative site to LIDL . The nearby Northen Access road which was built at considerable cost to the taxpayer for commercial and residential development has easy access, pedestrian and cycle way, together with Bus stops with shelters , though no current bus route. A Win / Win solution.

I trust the comments I have made above will be considered with the seriousness they deserve. Our rural communities deserve to be maintained for the wellbeing not only of the residents, but the environment as a whole. Llanmaes enjoys an abundnace of wildlife which needs to be preserved . Seing a pheasant aongside a woodpigeon crossing the road restores one's faith in our surroundings. Alongside the acres of wheat and corn ,they need those green field sites as do we.

Flood Alleviation
There is a desperate need for not just a flood alleviation plan, but action to protect the residents of Llanmaes from the continuing effects of flooding in the area. More properties have been affected this year. Recently our own 400-year-old property, which has never been previously affected, was subjected to a backlog of sewage from the main sewer in the road on which we live. Fortunately, a manhole on our drive gave way under the pressure, releasing water and sewage down the road. Otherwise, like other properties in the village we would be at risk of the property itself flooding with sewage.
I would call upon both the Vale of Glamorgan Council and the Welsh Government to come up with a coherent, joined up plan and solution to this long running problem and implement it with urgency.
No building should be allowed in the village until a solution has been completed, there is too much risk to existing properties.

Green Wedge/Conservation. Land Between Llantwit Major and Llanmaes Site D436 Proposal Number DNP2(6)
I would strongly support the proposal for a 'green wedge' for the land between the village of Llanmaes and the Llantwit major bypass, but this should also include the land currently under proposal for the above retail development site. This would protect this land from further hostile development proposals, protect the intrusion into the countryside and the setting of the Llanmaes Conservation Area and protect the village against physical and visual coalescence with a town, protecting its rural and village character. It would protect the setting of the Llanmaes Conservation Area as per the adopted Management Plan.

The conservation /green wedge between Llantwit Major and Llanmaes must be kept to protect the countryside and separate a village and a town.
The village currently suffers from flooding and a flood alleviation scheme is desperately needed. Further development of the village would be disastrous.
The proposal of a supermarket would be detrimental to a village and the infrastructure could not cope with increased traffic and heavy goods vehicles delivering to the supermarket.

Retail - Land at Bridge Farm House site ID 379 Proposal Number SP12(2)
This proposed development, currently subject to a 'Call In' by the Welsh government is at clashing odds with the village and rural community setting of Llanmaes. The large store and supporting structures and developments would be significant intrusions into the countryside and would result in the physical and visual coalescence of a small rural village with the town of Llantwit Major. It represents a significant intrusion into the countryside, is at odds with the proposal of a green wedge to protect the rural setting of the village and would be clearly detrimental to the Llanmaes Conservation Area. It is outside the RLDP's Strategic Growth Area.
