E-petition via Change.Org with 1376 signatures

Residents in Dinas Powys are objecting by means of this electronic version of the petition to the proposal to build 250new houses to the north.
They are concerned with a number of factors:
Flooding risks,
Poor transport facilities at Eastbrook railway station,
Schools will be over subscribed.
The medical centre will not be able to cope with additional patients.
The main road through Dinas Powys ( Cardiff Road ) will be even more gridlocked .
Loss of green wedge site.
The Council were unable to answer many questions during the drop on event at Murchfield Community Centre.
Residents claim not all studies have been carried out to support this proposed development.

I strongly disagree with the development planning reference HG1 KS2. This is due to the sheer lack of thought of impact both on the community of Dinas Powys and the surrounding wider areas. The proposed site would lead onto a main road that is already congested to the point of being ridiculous for both residents of Dinas Powys and those from Barry/Penarth who need to use the route to commute. Cardiff Road is consistently gridlocked to the point where proposing more houses and so traffic and cars is ludicrous. Where is the upgrade of infrastructure to support these additoinal cars and vehicles? I have lived in Dinas my whole life and there has never been an upgrade aside from the bus lane which does nothing to cut congestion on the road. The roads are not maintained as they are as they are covered in potholes causing damage to cars and you are sugessting a plan that would lead to more wear and tear. Public transport can also not cope with the demand already placed on it. I commute to Cardiff and, even with the addition of some new trains, they cannot meet the requirements of the number of people at peak times - many journeys lead to passengers being unable to get on the train at all and having to wait for a later one. Parking is already an issue for many with people parking on both sides of the road and causing congestion and people have already taken to parking on the pavement, particularly at teh bottom of St Davids Avenue on Cardiff Road which is causing obstructions for anyone with mobility issues or a pushchair.

The schools are already oversubscribed to the point where class numbers are unmanageable, I know this first hand from speaking to many teachers in teh infants school in particular. They are under resourced and do not have the manpower to provide one on one care that many pupils now require. This is also the case with the Doctors Surgey which is pot luck if you can get an appointment through relentless ringing at a certain time - how can this then justify putting more families in ach catchment area?

On flooding - as we have already observed with new develiopments in the village there has been an increase in run off which the brook and stream cannot cope with leading to significant flooding. The relatively new houses by Hebron Hall are already flooding in areas and we have seen numerous houses damaged by flood on Cardiff Road- how can any enviromental assesment worth anything suggest that building on a natural area that soaks up water will not increase flooding and approve this is simply unbelievable.

Opposition to Development Group
Help Save Dinas Powys
Petition of Objection to Vale of Glamorgan RLDP Plan 2021-2036 Planning ref HG1 KS2 - Site Proposal: 250 properties on land north of Dinas Powys, off Cardiff Road
We the undersigned formally object to the above-mentioned on the following grounds: Increased road congestion and pollution, flooding risk, doctors and schools are already at over capacity, IN active travel - Eastbrook station is inadequate and not accessible for everyone, discriminating against the minority, reduced green wedge and loss of village identity.

Could you please accept these comment with regard to this planning proposal for housing North of Dinas Powys off Cardiff Road.
I strongly object to these proposals for the following reasons:
- the traffic along Cardiff Road is already gridlocked most days at various times, not just rush hour. It is the main route into Cardiff form Wales’ biggest town, Barry, as well as Dinas Powys itself causing congestion and pollution along the route. So to add circa 500 additional cars and another set of traffic lights along this busy road is ridiculous.
- the bus lane where the new traffic lights are proposed, and the only exit route from the planned housing estate, is rarely used by buses. It is mostly used my taxis who cause the traffic lights at Cardiff Road / Redlands Road junction to turn red causing unnecessary delays.
- Dinas Powys is a bottle neck for both vehicle and bikes. Your active travel plan is insufficient for cyclists who are currently forced to use the centre of the road. Adding more cars on to the road would make it even more dangerous for cyclists.
- increased pollution for residents of Dinas Powys with the increase of cars on the road.
- I understand the need for extra housing and the pressure on local authorities to secure land suitable for housing, but not in this location where the only option for travel is on to an already busy and congested road.
- looking at the general plan for the area, it looks like this first site for development is the tip of the iceberg and further pieces of land in that area have already been allocated for housing. Dinas Powys is at breaking point with services at capacity and roads at gridlock! Please don’t let this happen. I already feel a prisoner in the village unable to leave without stress of being held in constant traffic. It only takes a small amount of road works, or even worse a road closure, to cause absolute chaos!

There should be no new houses built in Dinas Powys at all, one of the primary draws of the village is that it is a village. As new houses are constantly built on the edges the population is ever-increasing and that village identity is being lost.
But if new houses are to be built regardless of concerns about the loss of village identity then it should be considerably less than 250. 250 is an incredibly large number of houses to suggest building in an area where local GPs are at capacity and both primary and secondary schools are oversubscribed. The sheer number of houses will also cause a major increase in congestion - a problem Dinas is already facing.
The location proposed for these houses to be built is also unacceptable. Many homes in Dinas Powys already experience flooding when the weather is bad (as it so often is in Wales). Water run off from the Eastbrook site will enter the Cadoxton River which has burst and flooded homes here many times.
There are also concerns about the loss of wildlife the site will cause as it destroys habitats. The greenbelt between Dinas and Llandough will also be reduced.

It is respectfully requested that:
The allocation of Site SP4 KS2 be removed.

Objection to Allocation HG1 KS2 - Land North of Dinas Powys (SP4 KS2) This submission sets out an objection to the allocation of Site SP4 KS2 (Land North of Dinas Powys) within the Vale of Glamorgan Replacement Local Development Plan (RLDP). The allocation is considered unsound, inconsistent, and contrary to national planning policy, and is not supported by sufficient settlement-specific evidence.

1. Previously Rejected for the Same Constraints
The site was previously assessed during the 2011-2026 LDP process (Site 1098/CS.1) and rejected at Stage 2 due to "insurmountable constraints." Similarly, candidate site 2036/CS.2 (Land at Eastbrook) was rejected on the grounds that development would:
Represent unacceptable intrusion into the countryside
Promote coalescence between Dinas Powys and Llandough
Be subject to significant highway constraints
No clear evidence has been provided to demonstrate that these constraints have been resolved.

2. Green Wedge Conflict & Risk of Coalescence
The site lies wholly within the designated Green Wedge between Dinas Powys, Penarth and Llandough. The 2011 Green Wedge Background Paper identifies its purposes as:
Preventing settlement coalescence
Protecting open countryside
Maintaining settlement identity
Preserving the setting of built-up areas
The RLDP's Integrated Sustainability Appraisal (2023) confirms Green Wedges continue to protect settlement integrity.
Allocating ~250 homes on this land would materially reduce separation between Dinas Powys and Llandough, directly conflicting with paragraph 3.78 of Planning Policy Wales.
Paragraph 3.64 of Planning Policy Wales requires Green Wedges to be "soundly based." No robust evidence has been presented to justify altering this designation.
Once Green Wedge land is released, it cannot realistically be restored. Approval would create pressure for further incremental loss.

3. Inconsistent Candidate Site Assessment (BP18A) Background Paper BP18A shows clear inconsistencies.
Site SP4 KS2 (Site 444) was progressed, while overlapping or adjacent smaller sites were rejected: Site 356 - Land east of Pen-Y-Turnpike Road (rejected due to Green Wedge harm) Site 419 - Land at The Grange (rejected due to Green Wedge harm)
Site 423 Land North Dinas Powys (rejected due to sporadic countryside intrusion) These sites are smaller and would pose less risk of coalescence than SP4 KS2. The differential treatment lacks explanation and undermines transparency and credibility of the assessment process.

4. Highways, Traffic & Sustainable Transport
Previous Council findings confirmed the Station Road/Cardiff Road junction was operating at capacity. The main road through Dinas Powys is at a standstill in both directions for much of the day. The traffic coming from Penarth will back up due to the increased traffic (approx 500 extra vehicles on the road) resulting from 250 additional houses.
The RLDP does not provide:
Detailed updated junction modelling
Cumulative traffic impact assessment
Funded and deliverable mitigation measures
Planning Policy Wales requires development to avoid severe residual impacts on the road network and promote sustainable transport.
The Plan relies on aspirational measures without demonstrating modal shift sufficient to offset ~250 additional dwellings.

5. Air Quality Concerns
Air quality monitoring was undertaken adjacent to open fields, where pollutant dispersion is naturally favourable.
The survey effectively demonstrated acceptable limits because open land allows dissipation.
Introducing 250 homes would:
Alter dispersion dynamics
Increase vehicle movements
Create potential pollutant accumulation
No post-development dispersion modelling or cumulative emissions modelling has been presented.
There has been no focused monitoring at sensitive receptors such as local primary schools during peak term-time traffic.

6. Flood Risk & Drainage (TAN 15)
Parts of the Eastbrook area have known drainage and flood constraints.
The RLDP:
Defers mitigation to application stage
Does not provide robust cumulative runoff modelling
Does not clearly demonstrate compliance with current TAN 15 requirements including climate change allowances
The site proposed for development floods after the slightest rainfall. If this development did go ahead the water would be diverted toward the rest of the village who already experience severe flooding and the loss and distress that comes with that.

7. Wastewater & Sewerage Infrastructure
There is no published confirmation from Dwr Cymru Welsh Water confirming network and treatment capacity.
The Plan does not identify:
Required upgrades
Funding mechanisms
Delivery timescales
Infrastructure sequencing
Reliance on future upgrades without secured delivery undermines effectiveness.

8. Schools & Community Infrastructure
Previous assessments noted limited school and medical capacity.
Section 106 education contributions from earlier developments (including Taylor Wimpey funding originally linked to nursery and primary provision) have not resulted in clear, transparent delivery of additional school capacity.
Subsequent housing approvals (e.g. Bendricks / Hayes Road) have added pressure without clear education funding alignment.
The RLDP provides no:
Settlement-specific capacity study Confirmed expansion programme
Delivery timetable aligned with housing growth

9. Best and Most Versatile Agricultural Land
The site comprises Grade 2/3a agricultural land (Best and Most Versatile). Planning Policy Wales requires protection of such land unless overriding need is demonstrated. No published BMVassessment or alternatives analysis has been provided.

10. Placemaking & Settlement Character
The proposal represents a disproportionate extension relative to the scale and pattern of Dinas Powys. The allocation appears driven by housing numbers rather than:
Local character Infrastructure capacity
Community wellbeing
Sensitive placemaking principles

11. Loss of natural habitat for local wildlife
The land proposed for development is a natural habitat for many species including: Bats Foxes Tawny Owls Dragon flies Woodpeckers Sparrowhawks Greater Spotted Woodpeckers

12. Active Travel and public transport
The Council offers a narrative of active travel being a reasonable alternative to using vehicles. This has not been thought through properly. Many people have to take children to school, which they could not do by foot on on a bicycle. The same argument goes for people working in areas not accessible by public transport. The bus and train service running through Dinas Powys is insufficient for the residents currently living here so would not cope with the increased demand. The train station at Eastbook does not have a lift or a crossing for people with a physical disability or parents with a pushchair. The route to walk around to the other side of the train station would add an additional 20/30 minutes to the journey on foot.
Overall Conclusion
The allocation of HG1 KS2/SP4 KS2 is unsound because it is:
Not Justified Contradicts established Green Wedge purpose
Inconsistent site assessment
Previously rejected for unresolved constraints
Not Effective Infrastructure capacity (highways, schools, sewerage, drainage) not demonstrated
Over-reliance on future mitigation
Not Consistent with National Policy
Conflicts with Planning Policy Wales Green Wedge policy
Fails to demonstrate sustainable transport compliance
Risks loss of Best and Most Versatile agricultural land
Requested Action
It is respectfully requested that:
The allocation of Site SP4 KS2 be removed.

To summarise, the proposed development contradicts many of the stated objectives within the Deposit Plan and would have significant negative impacts on the community of Dinas Powys. Existing infrastructure, including roads, schools, healthcare services and drainage systems, is already under considerable strain, and further large-scale housing would worsen congestion, increase flood risk, and place unsustainable pressure on local services. The loss of valuable green space would damage local wildlife habitats, reduce opportunities for recreation and wellbeing, and undermine the rural character of the area. Rather than supporting sustainable, resilient communities, this development risks harming the environment, weakening community cohesion, and failing to meet the needs of both current and future generations.

Page 5: ‘The Vale has a skilled and adaptable workforce’ which ‘has enabled existing business to grow and thrive and has contributed to a reduction in outward commuting’.
As a resident that regularly commutes to a local school for work and the surrounding areas of Penarth, Barry and Llandough, I would highly disagree with this statement.
The traffic throughout Dinas is continually and regularly heavy and at times gridlocked, especially with the fact that Cardiff road is the only means of travel in and out of Dinas. The proposed entrance site at the point alone will severely impact this detrimentally.

Page 5: ‘Through investment in active travel, public transport, and broadband connectivity the rural vale is a living and working countryside supporting a network of sustainable and thriving rural communities’.
The train station at Eastbrook is only fully accessible to those able bodied members of the community. The station is accessed only via steps to each side of the track. Investment has not been undertaken despite it being flagged by the community. The notion of a ‘rural community’ will be no longer valid if the development goes ahead. The status of village for Dinas will be greatly diluted with the minimisation of the boundary with Llandough.

Removal of green space, along with the destruction of forests for building materials, is in direct contradiction of the terms ‘countryside’, ‘rural’, ‘sustainable’ and ‘thriving’ in any and all senses. This is before the consideration of the impact of flooding in the area which has already been seen within Dinas due to the imbalance of the water table owing to building on green space. More than 100 homes along Cardiff road experienced catastrophic flooding in December 2020. This is also in contradiction to the statement that ‘Places are safe, accessible and socially inclusive’. Many residents had to leave their homes with some elderly members sadly did not live long enough to return.

National resources Wales have been investigating the floods that occur within Dinas and have prepared a flood management scheme. This explores risks to flooding and plans to prevent future floods and in no way suggests that additional builds are a positive move to reducing further risk. In fact this is quite the opposite, with national resources Wales not being in agreement with the planned development. In fact, they detail a long term vision that includes ways to ‘protect, enhance and value the environment’, as well as ‘improve the resilience and quality of ecosystems’.

Objective 1: ‘Ensure that all new development and infrastructure is resilient to future impacts arising from Climate Change’.
Removal of green space will further impact the water table and will, again, ultimately affect the environment of the local area. Flooding is already a problem within Dinas, and this will add further negative impact. Not only will this impact homes, but wildlife. Surface drainage systems at present cannot cope with heavy rainfall, and floods occur with heavy rainfall. Further reduction of the water table will only serve to exacerbate this problem where water will have no choice but to drain to the lower areas of Cardiff road and surrounding fields with wildlife and farm animals. This has already been seen as a result of the recent build at the top of Murch Road, where the pedestrian lane through to Sully Road floods with just average rainfall, along with Sully road itself as a consequence. Waste pipe systems beneath Cardiff Road from existing homes are not without fault, with sink holes already discovered as a result within Chapel Close, heavily impacted by the drainage of excess surface water during rainfall. This problem has been looked at by Dwr Cymru on more than one occasion, the most recent being late 2023.
Taken from Natural resources Wales): “Green space also helps to keep towns and cities cool during heat waves. It helps to filter pollution from the air, reduces stress and promotes mental health and wellbeing”. The green space is needed to combat the effects of climate change. Removal of it will be not only reducing the ability of minimising this impact, it will actively be adding to it.

Page 5: ‘Development respects local character and contributes positively towards health and well-being’
Accessible green space respects local character and contributes positively towards health and well-being, not additional buildings that result in pollution, congestion, oversubscribed schools and healthcare.

Removal of green space will have a detrimental effect on those already resident within the community.

Taken from Natural resources Wales): Green space stimulates children to do better at school (Ref Children Nature Network)”, with ‘the provision of quality, accessible, local green space is critical in improving our health as a nation’”. Dinas has already seen increasing numbers of houses on a large scale and the impact is already apparent. Flooding, competition for schools and healthcare, increased congestion, inadequate roads for commute demands, poor road quality, reduction in the feel of a community, loss of wildlife, loss of green space. As well as generations that are displaying the effects of lockdown on their mental health and wellbeing, that need our support to thrive. This development will not provide that support. No part of these plans take into account our current and future generations. They only add challenges that will damage the community which they call home.

Post lockdown, many adults and children alike are struggling with mental health concerns as a result of time spent in isolation. This is becoming more and more apparent within school settings, and is apparent in schools within the community of Dinas. Knowing that children within the community use Seal park and the surrounding green space as a safe and private space for playing, exercising and socialising, changes in this will have a detrimental impact on this time and ultimately on their health and wellbeing. In addition to this the competition of school spaces will be massive, which will reduce what it means to feel part of a community, force families to travel to gain education, impacting congestion on the roads and family/work life balance, and reduce potential of building social bonds of children and families within the community. In accordance with the Future Generations Wellbeing Act 2015, and Act unique to Wales, huge impacts such as these should not be overlooked.

Objective 5: ‘Prioritising previously developed brownfield land for new development, directing development away from areas of nature conservation interest and safeguarding the sensitive natural environment from inappropriate development’.

The development in question is in complete contradiction to this claim. The build is inappropriate. There is no need for further housing within a community that cannot sustain it, in terms of schools, healthcare, and travel systems. In terms of the environment, there are many protected species of plant and wildlife that inhabit the green space in question. Wildflowers such as bluebells, bats and birds of prey thrive within the environment concerned. These are well known as commonplace within the area by local residents. “Given the available habitat (the river corridor through Dinas Powys) there’s potential for protected and notable species to be present, including: Bats, Otters, Reptiles, Amphibians, Nesting Birds (kingfisher is of particular interest as they usually nest within high riverbanks” (Taken from Natural resources Wales). These species are protected by law and specifically the Wildlife and Countryside Act 1981 which concerns the protection of bats. Bats will be negatively affected by the loss of their habitats, introduction of new buildings, as well as simply the addition of lighting. The proposed build will bring these in abundance and so will be highly detrimental to their survival.

Page 5: ‘Positive improvements have been achieved for residents living in the most deprived areas through improved access to employment, education, training, services, and investment in the built environment’.

Schools are currently at a maximum capacity. St Cyres alone received over 500 applications for pupils transitioning to secondary school this year, which is double its intake capacity. New residents will not be able to benefit from this proposed development as there simply is not enough space to accommodate, rendering this statement false. The only investment is in houses, which is not an investment to the environment. No additional schools, healthcare or travel systems have been included. Therefore, no further jobs have been created and so no positive improvements as the statement aims to promise.

Increasing the number of houses will result in increased strain on schools, increase pressure of families currently residing in Dinas in concerns over admissions for schools, and force children to travel further for education. This in turn will have negative effects on families by causing additional stress through further commute; earlier waking and leaving times; increased commute times; disjointed locality of friendship groups; reduction in community feel for pupils and young families as a whole; contributing in turn to poor community bonds and support and consequently well-being and mental health; as well as adding to the congestion within Dinas and surrounding areas. Additional congestion will also bring with it increased detrimental effects on the local and surrounding environment of car exhaust fumes.

In conclusion, the proposed development contradicts many of the stated objectives within the Deposit Plan and would have significant negative impacts on the community of Dinas Powys. Existing infrastructure, including roads, schools, healthcare services and drainage systems, is already under considerable strain, and further large-scale housing would worsen congestion, increase flood risk, and place unsustainable pressure on local services. The loss of valuable green space would damage local wildlife habitats, reduce opportunities for recreation and wellbeing, and undermine the rural character of the area. Rather than supporting sustainable, resilient communities, this development risks harming the environment, weakening community cohesion, and failing to meet the needs of both current and future generations.

1. “Key Site” on Cardiff Road
The proposed development of approximately 250 homes on land adjacent to Cardiff Road is fundamentally unsuitable for the following reasons:
Severe Traffic Congestion
Cardiff Road already experiences significant congestion, particularly during peak commuting hours and due to traffic associated with Llandough Hospital. Introducing a further 250 dwellings will substantially worsen traffic conditions, increasing delays, road safety risks, and air pollution.
Loss of Green Belt and Settlement Separation
This land currently functions as an important green buffer between Llandough and Dinas Powys. Development would erode the natural boundary that maintains the distinct identities of these communities. The loss of this separation would result in undesirable coalescence of settlements and permanent loss of open countryside.
Flood Risk and Environmental Impact
The area plays an important role as permeable agricultural land which assists with natural drainage. Development will increase surface water runoff and exacerbate local flooding risks. Additionally, this land supports wildlife habitats which would be significantly harmed by large-scale housing development.

RE: Vale of Glamorgan Replacement Local Development Plan (2021–2036) – Deposit Plan Consultation
I wish to submit a strong objection to the inclusion and consideration of the following proposed development sites affecting Llandough and the surrounding area.
This objection reiterates and strengthens concerns raised during the Preferred Strategy consultation in February 2024. Unfortunately, the Deposit Plan does not appear to have adequately addressed the fundamental planning, infrastructure, environmental and community concerns previously highlighted.

Remove the site

Objecting to development HG1 KS2 250 houses opposite Eastbrook Station.
As a resident of the village for over 20 years it's very clear the road through the village is at capacity every day at rush houe and frequently on weekends backing up from the merrie Harrier and verly slow traffick through the village to sully moors and barry.
The bus lane doesn't really help and the train is fine once you can get there and if you can park. Adding traffick from 250 houses can't help.
the other big problem is schools and the doctors are at capacity. Where will new comers be accomodated?
having walked the path through the site before the land is very wet and waterlogged so would present a challenge to build on plus loss of ground to soak up and store rainfall would only add to the risk of flooding in the village.
Wildlife would be affected as it's a very 'quiet' area undisturbed and I have often seen foxes crossing the road heading to casehill woods and likewise from the woods down through these fields from Pen Y turnpike road.
There is clear need for more housing but a development on this scale on this site is disproportionate and not helpful.

this development is just too much and in the wrong place.
traffic is already very bad on the road in and out of the village and that many houses will gridlock the road every rush hour.
There are not nearly enough places in the local schools and the doctors is full so how can these hundreds of new people going to access services?
more housing is needed but this is too much and too concentrated.
The ground is very wet and boggy so how can you build on that?

Planning Reference: HG1KS2

I am objecting to the building of these homes in Dinas Powys. It is completely wrong for this location. There are significant challenges already and these homes will exacerbate an already challenging situation. I live in Penarth and help care for my elderly mum who lives in Dinas Powys so I am often travelling down the Cardiff Rd towards Dinas Powys. I am often sitting in traffic jams, nose to tail all the way from Penarth to Dinas Powys and beyond. If my mum needed me urgently, I already worry about the time it would take me to get there and adding so many extra cars would cause so much more traffic, it will be complete deadlock and this causes me a lot of concern. There also a lot of potholes which would be made worse by a lot more traffic on the roads. This considerable increase in traffic at a constant standstill will also greatly affect air pollution and air quality, which I also worry about as my elderly mum has asthma which affects her a lot and she could be adversely affected by any decline in air quality in the area. As well as all these concerns the traffic deadlock would also present a significant risk by preventing the ability of emergency services to get to where they need to get to and therefore prevent existing and new residents from getting the emergency help they need. Lives would be lost by continuing with this development.

Transport links in the area are not good. Eastbrook station has inadequate parking and cannot be used by anyone with mobility issues/ prams etc. My mum cannot use it as she cannot manage all the steps across the tracks. And users from the new estate would again have to use the Cardiff Rd to get there, again increasing pressure on an already gridlocked road. This would be nightmare for local residents who will be continuously stuck in traffic.

I am also worried that the development will increase the risk of flooding as the road has flooded very close to my mum’s home and any increase in flooding could result in her home being flooded and a lot of damage, stress and trauma to my mum who is elderly and vulnerable and would find this situation impossible to deal with. Homes have been flooded in Dinas Powys and I do not think the Council should be building homes in a way which increases risk to other residents of the area.

I'm also worried about the lack of infrastructure such as schools and Doctors in the area. As you know a surgery closed in Penarth causing my mum’s surgery in Dinas Powys to have to take a significant number of extra patients. Since then, my mum has found it very difficult to get an appointment to see a Dr and all these extra households could only make this situation a lot worse. As a vulnerable, elderly person this is a great concern for me. There will also be no extra school for new residents of this new estate also putting pressure on an already difficult school situation. This is an unacceptable burden on already stretched services and should not be allowed. These extra homes would also put pressure on our hospitals and maternity services and other NHS services which are already stretched and waiting lists are already incredibly long. I myself recently waited nearly 5 years for a routine operation and this had a big impact on my life and I worry this would get even worse by the extra demand created by these new homes. The impact on people’s lives could be extremely detrimental as they wait even longer for these services.

The UK is extremely depleted for nature and the Vale is no exception. We have an incredibly small percentage of our land given over to nature and wildlife. Destroying this large area of nature will have a massive and devastating effect on our wildlife and this is unacceptable at a time when we should be supporting nature not destroying it. This development would eat into valuable greenbelt land and effectively merge Dinas Powys and Llandough. This would be completely unacceptable and should not go ahead. Greenbelt is there for a reason and it should be protected not removed. This development would be extremely bad for nature and the green belt and it should not be allowed to go ahead.

Dinas Powys is a small friendly village and it prides itself on its village identity. This large development would completely ruin this identity and alter the nature of the village for ever. This is not progress, it is the destruction of a valued and treasured identity and it should be allowed to happen.

As a resident of Dinas Powys, I strongly object to this development.
Flooding
A significant concern relating to this proposal is the increased risk of flooding. Following several recent developments in and around Dinas Powys, the village experienced notable flooding in 2020. These developments were constructed on former greenfield sites which previously absorbed substantial volumes of surface water during periods of heavy rainfall. The loss of this natural drain age capacity appears to have contributed to increased surface water runoff and flooding within
the community. It is therefore concerning that the Flood Consequences Assessment submitted in support of this application does not appear to reference or consider the flooding events experienced in 2020. The omission of this locally significant event raises questions about whether the assessment fully reflects the real flood risk affecting the area. Under Welsh Government planning guidance Technical Advice Note 15 (TAN15), updated in 2025, Local Authorities are expected to ensure that development proposals fully consider flood risk and consequences based on up-to--date flood maps and climate change projections, particularly on greenfield sites where development is strongly discouraged in flood-prone areas. Further development on fields that currently act
as natural water absorption areas is likely to exacerbate the problem and increase the risk of flooding for existing residents.
Traffic Congestion and Highway Capacity
Another major concern is the impact on the local road network. Cardiff Road, which runs through Dinas Powys, already experiences significant congestion, particularly during peak commuting hours. This road serves as a key route connecting the village with both Cardiff and Barry and is heavily relied upon by residents and commuters. With further housing developments planned in nearby areas, particularly in Barry, traffic volumes are already expected to increase. The addition of
approximately 250 new dwellings could reasonably introduce several hundred additional vehicles
to the local road network, potentially in the region of 500 extra cars. The current infrastructure already struggles to cope with existing traffic levels, and it is difficult to see how it could accommodate such a substantial increase without worsening congestion, increasing journey times, and
negatively affecting road safety and air quality.

Public Transport Accessibility (Eastbrook Station)
Concerns also arise regarding the reliance on the proximity of Eastbrook railway station as a justification for the sustainability of the development. While the station is geographically close to the site, it is a small facility with limited infrastructure and lacks adequate accessibility provisions. In particular, the station does not provide step-free access between platforms. Passengers returning
from Cardiff Central who need to access the opposite platform cannot use the footbridge and must
instead travel approximately one mile to find an alternative route around. This presents a significant barrier for people with mobility impairments, parents with prams, cyclists, and elderly residents. As a result, the station cannot reasonably be considered a fully accessible or practical
transport option for a large number of future residents, and reliance on it to support a development of this scale risks overstating the site's public transport accessibility.

Active Travel and Pedestrian Infrastructure
Concerns also arise in relation to the suitability of the proposed active travel routes associated with the development. The routes identified appear to rely heavily on existing infrastructure that is inadequate to safely accommodate increased pedestrian and cycling activity. For example, sections of pavement along the main road are particularly narrow and appear to fall below the recommended width for safe pedestrian use. Such constrained spaces make it difficult for pedestrians to pass
comfortably and are unsuitable for wheelchair users, mobility scooters, or parents with prams. Alternative routes identified appear to rely on private roads and involve steep gradients, requiring users to travel both up and down hills. The Active Travel (Wales) Act 2013 places a legal duty on
local authorities to plan for suitable walking and cycling routes that meet the needs of all users — including people with reduced mobility — and to provide accessible infrastructure that enables modal shift away from car use. These routes are therefore unlikely to be practical or accessible for many members of the community, undermining claims that the development promotes sustainable transport.

Loss of Greenfield Land
A further concern relates to the loss of greenfield land and its environmental function. The proposed development would remove land that currently performs an important role in absorbing rainfall and regulating surface water runoff. In addition to supporting natural drainage, this open
land contributes to the environmental quality and rural setting of the surrounding area. Its loss would reduce the landscape’s natural resilience to heavy rainfall events and contribute to the continued urbanisation of what is currently open countryside. The Welsh Government’s planning guidance consistently emphasises prioritising previously developed land and avoiding inappropriate
development on greenfield sites, particularly where it would compromise natural environmental functions.

Green Wedge Designation
The site also lies within land designated as a Green Wedge in the Vale of Glamorgan Local Development
Plan (Policy MG18), which seeks to prevent the coalescence of settlements and retain the openness of land between Dinas Powys, Penarth, and Llandough. Within these areas, development that prejudices the open nature of the land will not be permitted. This designation exists to restrict inappropriate development which would contribute to urban sprawl, erode landscape character, or
adversely impact the setting of existing communities. The construction of approximately 250 dwellings would represent a substantial encroachment into this protected landscape, undermining the purpose of the Green Wedge policy and the local plan’s objectives for managing growth
sustainably.

Pressure on Local Infrastructure and Services
The scale of the development would also place additional pressure on local infrastructure and public services. Facilities such as GP surgeries, schools, and other community amenities in Dinas Powys are already limited and serve the existing population. A development of approximately 250 homes would significantly increase demand for these services. Without clear and demonstrable plans for corresponding infrastructure improvements or expansions, there is a real risk that existing residents will experience reduced access to essential services — an outcome contrary to the Local
Development Plan which seeks to ensure new development adequately provides for community needs. In summary, the proposal raises serious concerns relating to flood risk, traffic congestion, inadequate transport infrastructure, poor accessibility, unsafe active travel routes, pressure on local services, loss of greenfield land, and the erosion of Green Wedge protections. Many of these issues directly conflict with Welsh planning policy (including TAN15 and the Active Travel Act) and the
Vale of Glamorgan Local Development Plan. Taken together, these issues suggest that the development
is neither sustainable nor appropriate for this location. For these reasons, I respectfully request that the application be refused.

I am objecting to the building of these homes in Dinas Powys. It is completely wrong for this location. There are significant challenges already and these homes will exacerbate an already challenging situation. I live in Dinas Powys and I am an elderly mum who lives on my own. I rely a lot on my daughter for help, who lives in Penarth. She is often travelling down the Cardiff Rd towards Dinas Powys and often sitting in traffic jams, nose to tail all the way from Penarth to Dinas Powys and beyond. If I needed her urgently, I already worry about the time it would take her to get here and adding so many extra cars would cause so much more traffic, it will be complete deadlock and this causes me a lot of concern. There also a lot of potholes which would be made worse by a lot more traffic on the roads. This considerable increase in traffic at a constant standstill will also greatly affect air pollution and air quality, which I also worry about as I have asthma which affects me a lot and I could be adversely affected by any decline in air quality in the area. As well as all these concerns the traffic deadlock would also present a significant risk by preventing the ability of emergency services to get to where they need to get to and therefore prevent existing and new residents from getting the emergency help they need. Lives would be lost by continuing with this development.

Transport links in the area are not good. Eastbrook station has inadequate parking and cannot be used by anyone with mobility issues/ prams etc. I cannot use it myself as I cannot manage all the steps across the tracks. And users from the new estate would again have to use the Cardiff Rd to get there, again increasing pressure on an already gridlocked road. This would be nightmare for local residents who will be continuously stuck in traffic.

I am also worried that the development will increase the risk of flooding as the road has flooded very close to my home and any increase in flooding could result in my home being flooded and a lot of damage, stress and trauma to me and as I am elderly etc I would find this situation impossible to deal with. Homes have been flooded in Dinas Powys and I do not think the Council should be building homes in a way which increases risk to other residents of the area.

I'm also worried about the lack of infrastructure such as schools and Doctors in the area. As you know a surgery closed in Penarth causing my mum’s surgery in Dinas Powys to have to take a significant number of extra patients. Since then, I have found it very difficult to get an appointment to see a Dr and all these extra households could only make this situation a lot worse. As a vulnerable, elderly person this is a great concern for me. There will also be no extra school for new residents of this new estate also putting pressure on an already difficult school situation. This is an unacceptable burden on already stretched services and should not be allowed. These extra homes would also put pressure on our hospitals and maternity services and other NHS services which are already stretched and waiting lists are already incredibly long. My daughter recently waited nearly 5 years for a routine operation and this had a big impact on her life and I worry this would get even worse by the extra demand created by these new homes. The impact on people’s lives could be extremely detrimental as they wait even longer for these services.

The UK is extremely depleted for nature and the Vale is no exception. We have an incredibly small percentage of our land given over to nature and wildlife. Destroying this large area of nature will have a massive and devastating effect on our wildlife and this is unacceptable at a time when we should be supporting nature not destroying it. This development would eat into valuable greenbelt land and effectively merge Dinas Powys and Llandough. This would be completely unacceptable and should not go ahead. Greenbelt is there for a reason and it should be protected not removed. This development would be extremely bad for nature and the green belt and it should not be allowed to go ahead.

Dinas Powys is a small friendly village and it prides itself on its village identity. This large development would completely ruin this identity and alter the nature of the village for ever. This is not progress, it is the destruction of a valued and treasured identity and it should be allowed to happen.

250+ new houses, Cardiff Road will increase traffic, so busy in the mornings during the week but also on the weekends. With the current traffic it can take up to 5 minutes trying to get out of my estate and onto the main road through Dinas Powys.
The roads are not fit for purpose with all the pot holes and having to swerve to avoid hitting them, but with a potential of an extra 300-500 additional cars the roads will need resurfacing weekly which no doubt the council will increase our council tax even more.
Dinas Powys infant school is on the main road and I'm sure the air pollution is currently already high putting the lives of the children at risk.
I really enjoy living in Dinas Powys village - seeing green land instead of concrete / houses which could potentially be the case in the future.
Please think of us residents and not just about making money from these housing developers!

Objection to RLDP and Site Ref: HG1 KS2
Please find below my objections to the RLDP and Site Ref: HG1 KS2 – the proposed
development of 250 homes in Eastbrook, Dinas Powys Vale of Glamorgan (Ref:444).
It is framed specifically for Welsh Planning Practice, TAN guidance, Welsh Government Policy and Fire and Rescue Expectations in Wales.
Additional Objections of; Hard Constraints not being adhered to, the suppression of Reporting on Dinas Powys Flooding in the RLDP, Policy Conflicts and Contradictions, Increased levels of traffic and pollution, Failure to identify the protected and endangered wildlife species evident
within the proposed development area, and the increase of additional Patients to adversely affect and impact the quality of NHS services within our community.
Should you have any queries, or wish to discuss any of the points further, please do not hesitate
to contact me.
My objections are as follows:
1. Objection: Requirement for Two Accesses for
Developments Over 100 Dwellings (Wales)
1.1 Summary Position
The proposed development exceeds 100 dwellings yet relies on a single point of access to the public highway.
In the Welsh context, this is not acceptable.
While no single statute sets a numeric threshold, the combined weight of:
• Planning Policy Wales (PPW11)
• TAN 18: Transport
• Welsh Fire & Rescue Service operational requirements
• Manual for Streets (as adopted in Wales)
• Local Highway Authority practice across Welsh authorities
• Appeal precedent in Wales and England
creates a clear and compelling expectation that large residential schemes must provide two independent access points, or at minimum a fully engineered emergency-only secondary route.
The proposal fails to meet that expectation and therefore presents an unacceptable risk to life, property, and network resilience, contrary to national policy and good practice.
1.2 Planning Policy Wales (PPW11): Network Resilience and Safety
PPW11 places network safety and resilience at the heart of transport planning.
Key principles include:
• PPW11 §4.1.9 – development must ensure “safe, efficient and reliable” access.
• PPW11 §4.1.31 – transport infrastructure must be “resilient to disruption”.
• PPW11 §4.1.52 – planning must support emergency access and avoid creating unsafe environments.
A single access serving over 100 dwellings is inherently non-resilient.
If blocked by:
• a collision,
• a fallen tree,
• flooding,
• a utilities failure,
• or even routine roadworks,
the entire estate becomes inaccessible to emergency services, directly undermining PPW’s requirement for resilient, safe access.
1.3 TAN 18: Transport – Safe Access and Emergency Provision
TAN 18 does not set a numeric threshold, but it is explicit that:
• Access must be safe for all users at all times.
• Emergency access must be maintained under all foreseeable conditions.
• Layouts must avoid single points of failure.
TAN 18 repeatedly emphasizes the need for robust access arrangements and the avoidance of designs that compromise emergency response.
A single access serving a large population is the textbook example of a single point of failure.

1.4 Welsh Fire & Rescue Service Requirements
Fire & Rescue Services in Wales (South Wales, Mid & West Wales, and North Wales)
consistently advise that:
• Large residential developments should not rely on a single access.
• A secondary access or emergency-only route is required where more than ~100 dwellings are served.
• Blocked access routes are a critical risk factor in fire fatalities and delayed response times.
This is grounded in:
• The Fire and Rescue Services Act 2004 (duty to respond effectively).
• Approved Document B (access for fire appliances).
• BS 9991 (resilient access for residential developments).
In practice, Welsh fire authorities routinely object to single-access schemes above 100 dwellings unless a fully engineered, unobstructed emergency route is provided.
1.5 Manual for Streets (MfS) – adopted in Wales stresses
• Network permeability
• Avoiding cul-de-sacs serving large populations
• Ensuring emergency access under all conditions
MfS does not set a numeric threshold, but its design philosophy is clear:
Large developments must not depend on a single access point.
1.6 Local Highway Authority Practice Across Wales
Across Welsh LPAs, the working norm is:
• Up to ~100 dwellings – single access may be acceptable if geometry is excellent.
• 100–150 dwellings – strong justification required; emergency access normally mandated.
• 150+ dwellings – two accesses are expected as standard.
Authorities including:
• Vale of Glamorgan
• Cardiff
• Rhondda Cynon Taf
• Carmarthenshire
• Flintshire
all routinely require two accesses or a dedicated emergency route for schemes of this scale.
This reflects risk-based practice and lessons learned from blocked-access incidents.

1.7 Appeal Decisions: Consistent Support for Two Accesses
Inspectors have repeatedly upheld refusals where:
• A single access serves >100–150 dwellings, and
• No secondary emergency route is provided.
Key themes in appeal reasoning include:
• Unacceptable risk to life and property
• Failure to ensure resilient access
• Conflict with national policy on safe and reliable transport networks
• Over-reliance on a single vulnerable point of access
Conversely, appeals succeed only where:
• A fully engineered emergency-only link is provided, or
• The dwelling count is significantly lower.
The proposed development falls squarely into the high-risk category.
1.8 Risk Assessment: Why a Single Access is Unacceptable
A single access serving over 100 homes creates:
1. Life-safety risk
Emergency services may be unable to reach residents during:
• fires,
• medical emergencies,
• flooding,
• or road obstructions.
2. Evacuation risk
Residents may be unable to leave during:
• fire events,
• gas leaks,
• or environmental hazards.
3. Infrastructure vulnerability
One incident can isolate the entire estate.
4. Policy conflict
Fails PPW11, TAN 18, and the Fire & Rescue Services Act duty to maintain effective response capability.

1.9 Conclusion
The proposal’s reliance on a single access for a development of 250 dwellings is:
• Contrary to PPW11 (safe, resilient access)
• Contrary to TAN 18 (avoid single points of failure)
• Contrary to Fire & Rescue operational requirements in Wales
• Contrary to Manual for Streets principles
• Contrary to established Welsh LHA practice
• Unsupported by appeal precedent
The development therefore presents an unacceptable and avoidable risk to residents and emergency responders.
A second access, or at minimum a fully engineered emergency-only route, is essential to make the scheme safe and policy-compliant.
2. Objection: Hard Constraints have not been Adhered To
2.1 Highways says that Persimmon cannot pencil in the ‘secondary’ or ‘emergency’ access. Persimmon Failed to Do a Traffic Study to Contest Highways View.
2.2 There is no Proposal to bring pedestrian or cycle access up to Welsh Government Standards.
2.3 The Proposed George’s Row and Seel Park routes to Eastbrook Station and Camms Corner shops do not work.
2.4 The highway adjacent to the site and providing ingress and egress to any homes built there is on the most congested road within the Vale of Glamorgan. As such it is deemed as traffic sensitive under the terms of the
New Roads and Street Works Act 1991. Any planned development is clearly contradictory to both the spirit and the intention of the legislation.
2.4 Risk Assessment: Why Failure to Provide this Information is Unacceptable
The highway proposal for this scheme is deemed as traffic sensitive under the terms of the New Roads and Street Works Act 1991. Any planned development is clearly contradictory to both the spirit and the intention of the legislation.

Highways’ objections have not been met, particularly around Active Travel and transport requirements. Highways documents state the Active Travel and busm improvements must be provided. Persimmon has not agreed to these.
Persimmon’s assessment shows walking and cycling routes fail to meet required width standards, and alternative routes via Seel Park or alleys are unsuitable.
Connections to Eastbrook Station are considered not feasible due to limited road space for Active Travel-compliance designs.
Cardiff Road is too narrow for safe Active Travel access; southern access options are also unfeasible without major property purchase/demolition.
Policy requires public transport improvements, but Persimmon proposes no new bus infrastructure, and their designs do not accommodate proper bus stops.
Highways advise that the above points are a Welsh Government Requirement for all new developments. This information has not been provided. The RLDP Team need to answer these hard constraints as well as report on amending the draft, prior to any approval.
3. Objection: JBA Consulting Suppressed Dinas Powys
Flooding in the RLDP Documents (Wales)
3.1 Risk Assessment: Why Failure to Report this Information is Unacceptable
Their Strategic Flooding Assessment (SFCA) had to record details of historical flood events, yet omitted the Dec. 2020 flooding of 100 homes in Dinas Powys. This same company (JBA Consulting), wrote its Section 19 legal report in 2021. Their SFCA just mentions that the
flooding measures dealt with the problem – yet their 2021 report:
Recommends that NRW assess viability of options to manage the flood risk across Dinas Powys; for DCWW to assess the viability of offline storage for the Cae’r Odyn surface water system.
There appears to be a cover up of these measures that have been clearly ignored. On their map, located on the last page of the SFCA, that proposes woodland planting to hold-back rainstorm run-off, on part of the proposed Persimmon’s Eastbrook site. The map is only indicative giving no source for the data. A full survey is still required.
The reports that are provided, need to be accurate, honest, transparent and compliant with legislation and policy. This is not. A full survey needs to take place to establish the full potential for flooding measures within Dinas Powys and the proposed Eastbrook Development
Site.

4. Objection: Policy Conflicts and Contradictions
4.1 Policy Conflict: Fails PPW11, TAN 18, and the Fire and Rescue Services Act – A duty to maintain effective response capability.
4.2 The proposal’s reliance on a single access for a development of 250 dwellings is Contradictory:
• Contrary to PPW11 (safe, resilient access)
• Contrary to TAN 18 (avoid single points of failure)
• Contrary to Fire and Rescue Operational Requirements in Wales
• Contrary to Manual for Streets principles
• Contrary to established Welsh LHA practice
• Unsupported by appeal precedent
The development therefore presents an unacceptable and avoidable risk to residents and emergency responders.
A second access, or at minimum, a fully engineered emergency only route, is essential to make the scheme safe and policy compliant.
4.3 The Welsh Government has placed a physical and ideological moratorium on the building of new roads, an example of this is the blocking of a by-pass around Dinas Powys:
The proposed plans show the building of roads on the proposed development to serve the new residents. This is clearly contradictory to the stated aims and rules imposed by the Welsh Government
5. Objection: Additional
5.1 Unacceptable Increased Levels of Traffic on Cardiff Road Resulting in Increased Air Pollution:
With the proposal of 250 plus, additional dwellings, assuming a minimum of two car each house hold, that is an increase of a minimum of 500 cars (although many households have 3 cars, 1 each plus a works vehicle), that will require access onto Cardiff Road and produce increased air pollution. This is unacceptable. For the Local Authority appointed consultant to advise that there
is an unlikely increase in pollution levels is both implausible and raises issues of competence, and integrity and should be questioned further.

5.2 Failure to Undertake the Appropriate Environmental Studies, at the Relevant Times of the Year to Assist in Identifying the Protected and Endangered Species Evident within the Proposed Development Area:
In light of the Environment (Principles, Governance and Biodiversity) Wales Bills, passed by the Senedd on 24th February 2026, it is now even more clearly unacceptable that this plan does not establish legally binding biodiversity targets. The new Office of Environmental Governance is established to hold public bodies to account. The landmark legislation is explicitly framed as a response to the nature and climate emergencies and is intended to halt and reverse biodiversity and decline in Wales. Proceeding with the allocation of HG1 KS2 Eastbrook – destroying a functioning green wedge and wildlife habitat without clear evidence of biodiversity enhancement – directly contradicts the spirit and intent of this new law and the wider duties under the Environment (Wales) Act 2016.
These protected and endangered species present in Eastbrook include:
• Hazel Dormice: These are found in the woodlands and hedgerows adjacent to the Eastbrook fields. There is no visible hazel dormouse survey provided.
• Otters: Evidence of otters, which are protected, have been recorded in the vicinity of the Eastbrook. There is no visible otter survey provided.
• Bats: Various species of bats, which are protected, use the area as a habitat, as well as for foraging and commuting. There is no visible bat survey provided.
• Badgers: These are present and are protected, given the suitable habitat. There is no visible badger survey provided.
• Kingfishers: These protected bird species are noted in the area. There is no visible kingfisher survey provided.
• The High Brown Fritillary Butterfly: one of the UK’s most threatened species, is found in the fields of Eastbrook, as well as throughout the Vale of Glamorgan. There is no
visible High Brown Fritillary Butterfly survey provided.
• Gold Crested Newts: endangered and protected, have been identified in the fields. There is no visible newt survey provided.
5.2.1 Summary:
This proposed development area, known as greenfield sites in Eastbrook, Dinas Powys, serve as a vital habitat and corridor for this wildlife.
Appropriate environmental and ecological studies, surveys and reports need to be carried out, at the relevant times of the year, specifically focusing on the above noted and sited endangered species, in and around this proposed development area. These surveys need to be made visible and provided within the RLDP and HG1 KS2 Eastbrook documentation.

5.3 Additional Patients to Adversely Impact Current and Existing Quality of Services and Resources.
Our schools, GP surgeries and emergency services are already overstretched. Adding hundreds of new residents with committed, funded infrastructure will make life harder for everyone who already lives here. This undermines the ‘A More Equal Wales’ and ‘A Healthier Wales’ goals of
the Well-being of Future Generations Act 2015, and fails the RLDP tests of soundness on effectiveness and deliverability.
The likelihood of an excess of 500 new patients being registered at the Dinas Powys Medical Centre will further impact and degrade the quality of services afforded to local residents, which are already far below standards prescribed by the Welsh Government.
6. Conclusion:
This development would clearly have a substantial negative and adverse impact on the residents and wildlife of our local community, and is completely contradictory to any Local Authority or Welsh Government stated aim to protect or even improve the community in which we live.
It is also contradictory the stated commitment to nature, climate, land and biodiversity. The LA and Welsh Government declared a nature emergency in 2019 and then again in 2021, and this proposed development, as well as the lack of genuine and actual reporting regarding the endangered and protected species of wildlife, is in complete contradiction to this. (7 Key Site Supporting Information >KS2 Land North of Dinas Powys>Green Infrastructure Statements). For all of these reasons, the permanent loss of green wedge space, the unresolved safety issues, the flood risk, the failure to protect and enhance biodiversity, the lack of supporting infrastructure, the catastrophic increase in traffic and pollution and the general harm to our community’s health and well-being, I strongly object to HG1 KS2 Eastbrook.
Whilst the need for further housing is not in dispute, this is the wrong site as clearly outlined above and the consequences would be irreversible. Please remove HG1 KS2 Eastbrook from the RLDP with immediate effect.
Furthermore, as determined by the Welsh Government (A More Equal Wales: mapping guide, 2025), the use of relevant tools and standards such as:
The EHRC Measurement Framework, National Indicators for Wales and EHRC is Wales Fairer?
2018 Report, The National Participation Standards for Children and Young People, The Future Generations Commission Involvement Journey Tool, the 5 Principles of Co-Production, outline the requirements of the Public Sector Equality Duty Specific Duties, in relation to engagement and consultation, to identify where a public body can have the greatest impact in reducing inequalities of outcome, minimizing disadvantage, but also to inform equality and well-being objectives. There was no evidence of these being utilized, visible or provided.
The Welsh Government further recommends the use of EHRC Public Sector Equality Duty Guide, the Future Generations Report Chapter 4, and the Future Generations Report 2020 ‘A More Equal Wales,’ section for both engagement of local stakeholders and for the setting of objectives. Again, the use of these was not evidenced, visible or provided.
The Welsh Government further emphasizes the consideration of the Well-being Future Generations (Wales) Act 2015 ways of working in particular ‘Integration’ to identify how a public body’s actions impact all of their objectives as well as the objectives of other nearby
public bodies and Public Service Boards. There was no evidence of this being considered or that the Future Generations Framework was utilised.
The Welsh Government further advises, under ‘Engagement, Involvement and Consultation’ that
public bodies need to:
• ‘listen to, and work with members of their communities which will enhance decision making resulting in better outcomes for all.’
• ‘…to facilitate the active participation of stakeholders in an open and ongoing dialogue…’
• ‘Apply the sustainable development principle and the five ways of working, including involving people with an interest in achieving the Well-being goals.
I would ask, where is the evidence that all the above listed frameworks, guidelines, legislation, policies, have been considered, implemented and adhered to?
These guidelines, standards, frameworks, policies and legislation, as well as engagement, and involvement of local residents living within the communities affected, are all matters that should be taken into account and followed prior to matters going out for consultation and prior to any
decision being made, and should not be used as a hindsight, reflective practice, as appears to be the current accepted practice.
I would urge the Councilors within the Vale of Glamorgan Local Authority to abandon this proposed development plan while they are still in a position of authority to do so. I would further urge the elected Councilors to be mindful of the fact that myself and my fellow residents will judge their actions on this, and other, matters, when next having the opportunity to vote on local elections. Honesty, openness, transparency, as well as perceived competence, adhering to (and not ignoring or contradicting) policy and legislation, as well as listening to the voice of the people (that the Vale of Glamorgan Council serve), and protecting and preserving environment as well as the health and well-being of the people, animals and wildlife that all reside within the Vale of Glamorgan, will all be assessed and measured.
I would be grateful for confirmation that my objections have been formally received and noted.

I would also be grateful for a formal reply in respect to my previous objections, as I never received a reply in respect to the Cosmeston Nature Reserve and Aqua Park objections, despite Mr Goldsworthy advising that he would respond to the questions that I raised, after the meeting
in November 2025. To date, I have not received a formal response to that matter, so I am requesting a response in respect to this matter. I trust that the Vale of Glamorgan Council will now withdraw the RLDP and abandon this
proposed development plan for Eastbrook, Dinas Powys, until such time as the appropriate and accurate reports are obtained, surveys carried out properly and within appropriate seasonal timescales, as well as the aims, commitments, policy and legislation of both Welsh Government and the Local Authority are not contradicted and the current levels of traffic on Cardiff Road may be addressed, prior to making the existing problem even worse. I thank you for your consideration in this matter and look forward to hearing from you in due course

There is a serious concern that the development will increase flood risk. Dinas Powys experienced significant flooding in 2020, largely following new developments built on former greenfield sites that previously absorbed large amounts of rainfall. The Flood Consequences Assessment submitted with this application does not appear to reference these events, which raises doubts about whether the assessment fully reflects the actual flood risk in the area. Further development on land that currently
acts as natural drainage is likely to worsen flooding for existing residents.
Cardiff Road already experiences heavy congestion, particularly during peak commuting hours. The addition of around 250 homes could introduce up to 500 extra vehicles, placing further strain on an already busy road network. This would likely increase journey times and could negatively affect road safety and air quality.
Although Eastbrook railway station is located nearby, it is a small facility with limited infrastructure and no step-free access between platforms. Passengers returning from Cardiff who cannot use the footbridge must travel roughly a mile to access the opposite platform. This makes the station difficult to use for people with mobility issues, parents with prams, cyclists, and older residents. As a result, it cannot realistically support the transport needs of a development of this scale.
The proposed walking and cycling routes also raise concerns. Much of the existing pavement along the main road is very narrow and appears to fall below the recommended minimum width of 1.5 metres, making it difficult for pedestrians to pass and unsuitable for wheelchair users or prams. Other suggested routes rely on private roads with steep gradients, which are unlikely to be practical for many users. These routes do not provide a realistic alternative to car travel.
The development would also result in the loss of greenfield land that currently helps absorb rainfall and manage surface water. In addition to its drainage function, this open land contributes to the environmental quality and rural setting of the area. Its loss would reduce the landscape’s natural ability to cope with heavy rainfall.
The site lies within a designated Green Wedge, which exists to prevent settlements merging and to protect open countryside. Building approximately 250 homes in this location would represent a significant and permanent encroachment into protected land and would undermine the purpose of the designation.
Finally, the scale of the development would place additional pressure on local services such as GP
surgeries, schools, and other community facilities, which already serve the existing population. Without clear plans to expand local infrastructure, there is a risk that access to these services will worsen for residents.
Taken together, these issues raise serious concerns about flood risk, traffic congestion, inadequate transport infrastructure, loss of greenfield and protected land, and increased pressure on local services. For these reasons, the proposal does not appear to represent sustainable development and should be refused

As a resident of Dinas Powys, this submission focuses on Site Reference HG1 KS2 Land to the North of Dinas Powys. My thoughts, concerns and objections are as follows:
It will result in more traffic on the already congested highways running through Dinas.
We will lose a green space which is nice to walk across, there are lovely birds, plants and fauna and it is important for mental and physical health and wellbeing.
The increased run off - from the roofs and drives of properties, the paths and road network - will add to the large volume of water in the Eastbrook river. The ground absorbs water and releases it slowly. The land in question is a natural sponge. By building on it, you are taking that away. As a former farmer, I know. SuDS wont provide a solution, they wont take the volume of water which will eventually run into the Cadoxton river after the Eastbrook river - which are already choked up.
As an electrician, when Dinas Powys flooded in December 2020, I was wading through water to get to properties if people who had been flooded, in order to make their electrical installations safe.
The development would place increased demand on utilities - the grid is unable to cope as it is. We have experienced a number of electrical power cuts.
The proposal is not sustainable where there are no local services - schools, doctors, dentists are all oversubscribed.
The site is a distance form Dinas Powys / Llandough amenities such as shops and for walker / cyclists / wheelchair users it is not feasible.

Traffic Congestion
Currently the main route(s) out of Dinas Powys ; Cardiff Rd and Pen-y-Turnpike Road are already heavily congested at peak times this is further exacerbated when an accident occurs and emergency vehicles require urgent access through the village. One of the key bottlenecks affecting this at the moment is the junction with Redlands Road the primary entrance to the suggested site is next to this bottleneck and adding potentially 500 more vehicles to this already hectic congestion at the point of the bottleneck is going to cause severe disruption to the Emergency services and will undoubtedly cost lives. The air pollution of this increasingly growing stream of slow moving traffic is not to be underestimated either for people living with conditions such as Asthma and COPD, also the additional traffic will back up next to the primary school on Cardiff Rd.
The Active Travel Plan Proposed by Persimmon is fundamentally flawed Trains to Cardiff at peak times are already overcrowded / full to capacity at peak times in the morning and evening by the time the trains arrive at Eastbrook. on many occasions passengers at Cogan are left on the platform due to trains being full. There is also no facility at Eastbrook station for persons with mobility issues or parents with pushchairs to cross the line. Local schools are already at capacity therefore any new intake of children would need to travel by road outside of the village adding to congestion at peak times. Increased Flooding.
The ground where this site is proposed is already saturated and is hence holding back a tremendous amount of rainwater from entering the Victorian drainage system along Cardiff Road. placing a concrete slab along many thousands of square metres of this green belt will instantaneously purge any rainfall in the future directly into Eastbrook putting the current properties around the site at severe risk of flooding along with properties downstream of the site within the village which are already in a Floodrisk area. this floodrisk area will grow until unethical schemes such as this are stopped on greenfield sites upstream. Dinas Powys Medical centre have not been consulted over this process and are currently at capacity with limited availability to serve the current patients. additional patients of this number would put them in breach of current Government guidelines of practitioner to patient support. The Local schools are also at capacity and have also not been consulted about where any additional children would be educated and by whom ?

In Conclusion this choice of site benefits no-one with the exception of the Persimmon shareholders who will gladly take their dividend payments without giving a 2nd thought towards paying for the infrastructure improvement absolutely necessary for this project to go ahead as suggested. There are many brown field sites available where a whole new community can be set up and established. People have to live somewhere but this should not be at the expense of the Eco system as without that there is no life.

I'd like to object to the proposed housing development at the North of Dinas Powys, off Cardiff Road. I think the location of this proposed housing development is preposterous and will further put pressure on the village, not only with increased traffic but also to its services. Dinas Powys is at capacity as is Cardiff Road itself. Leaving the village, especially towards Penarth/Cardiff, is a constant struggle whatever time of day. The increase in vehicles from the proposed new housing estate ,together with the new traffic light system that will be introduced, will cause further congestion and pollution.

I object to planning permission for 250+ houses being built on cardiff road at the cardiff end of dinas powys for a number of reasons.
1) The road is currently unable to accommodate the current traffic levels once you add left turns towards cardiff and right turns into the estate from cardiff direction will cause longer tailbacks in both in and out of dinas powys. This is also very close to a merge area on the road into dinas powys so this will cause more traffic chaos in that area. This is also at a junction where people jump the red light from Redlands road. This will cars coming from the estate will have to go across a bus lane. If there is plan for the pen-y-turnpyke to be used as a exit and entrance this will cause more havoc on a road that is already to fast and to narrow this will cause deaths on that road.
2) The schools in the local area are already over capcity and the education is already struggling. This is not helped by the low level of recruitment of teachers across the country.
3)The areas gp facilities are stretched to the limit as it is hard to get appointments as is. This has caused health deteration of people in the local area. I have had to attempt for numerous days in being unable to get appoiments. This will cascade into hospitals as well.
4) the transport in the area is not fit for purpose and is struggling already. Train stations are a distance away so this will cause more traffic for people to park in the car parks so means more traffic on road as well to go to the parking for the train stations. The buses are being cut and the buses are not getting any bigger same as the trains so more people will want to use them and becames more differcult to use them.
5) while the building of these houses this will cause disturbance to the wildlife in the area and could cause in balance in nature.
6) recently Dinas Powys has been plauged by water issues recently burst water mains depriving local area without water. This has also happened to the electricity. It is concerning of the state of the gas supply. The water treatment plant stinks with current supply of waste water and will get worse.
7)fields should be protected as more houses will result in flooding as the ground absorbs the water and helps protect the road that recently has been flooding from poor maintenance of the drains by the council.
Please take this into consideration and reject the planning for the houses.

I write to formally object to the allocation of Site HG1 KS2 – Land North of Dinas Powys within the Replacement Local Development Plan. I believe the site is unsuitable for the proposed development, based on inaccurate assumptions within the access and transport statement, insufficient consideration for the potential flooding risk for both the development and the fluvial network, and the impact on the village of Dinas Powys.

Transport
* the modelling associated with the access and transport statement considers a five-day average to determine peak traffic flows. This is incorrect given there is clear increases in commuting traffic on Tuesday-Thursday, with typically people working from home on Monday and Friday. As such the traffic modelling that the whole statement is based on fails to identify the true 'peak' of traffic. Furthermore, peak traffic flows in the area are from 7.00 - 10.00 and so this window of survey fails to capture the full picture.
* the access and transport statement itself acknowledges "the Cardiff Road corridor currently operates effectively as one long dynamic queue during peak periods" but then states that the level of traffic growth will unlikely materialise. This is in spite of their own (flawed, see above) modelling indicating a 5% impact with the development in place for am transport.
* the viability of the settlement relies on the use of public transport and walking to reduce car journeys. This fails to acknowledge the 2023 National Travel Survey which states that 67% of journeys to work are by private car, and given the nature of the development working-age people would be the primary market
* further to this, the access and transport statement highlights the proximity to Eastbrook station. This station is DDA compliant as there is no ramp/lift to allow for access to both platforms, and as such the use of the train is excluded to those who could live in the proposed development. It should also be noted that the train network in the morning is particularly oversubscribed and no modelling has been provided that demonstrates additional train passenger capacity to be accommodated.
* related to the points above, residents in the proposed development would need to use their vehicles to be able to access retail, as there is none within easy commuting distance. The assessment of less than 2km of walking being a suitable threshold for considering facilities in the locale fails to account for those carrying purchases. Note the appendix to the access and transport statement states that a mobility access hub should be built into the development, but this is not shown on the plans provided.
* the access and travel statement summarises with the statement that "It is therefore concluded that the site is suitably located for a residential development which could be delivered without detriment to highway safety and would additionally be able to take advantage of existing and proposed active travel connections to key locations such that future residents would not be required to rely on the private car." This takes no account for where people work, who would be moving into the development, personal preference of travel - and is not justified within the work shown.
* all traffic modelling fails to acknowledge the impact of construction traffic on the transport network, which would have a much more significant effect that the modelled private vehicles.
Flooding
* Flooding of East Brook and the River Cadaxton in Dinas Powys is known. Schemes proposed by NRW to address the flooding have not been brought forward
* The site currently has multiple water courses classified as "surface water and small watercourses", in both Flood Zone 2 and 3. As part of any Flood Consequence Assessment (FCA), the development would need ensure, accounting for climate change, that the properties were not at risk of flooding. This may result in significant import of material to raise levels
* The site is clearly slow draining, as evidenced during rainfall events by the extent of standing water/saturated ground. The drainage proposal provided by JBA is based on soakways/SUDS - these are unlikely to be viable if the ground is this impermeable - likely resulting in mass earthworks to create swales/attenuation cells etc
* Welsh Government TAN 15 states that the development needs to demonstrate that it will not cause or exacerbate the nature of frequency of flooding. No confidence is provided from the supporting documents, other than "SUDS" - see point above
Village Impact
* PPW 12 states that "places grow and develop in a way that uses land efficient... the location of housing,employment and leisure and other facilities are planned to help reduce the need to travel". This is not being appropriately considered in the location of this development, given that it is on the edge of an already stretched village whereby a significant part of the community around Eastbrook station already do not have easy access to leisure or retail facilities.
* PPW12 also states that a 'green wedge' is required to separate communities and prevent con-urbanisation. This land was previously designated as part of the green wedge, but this has been pushed aside given the interest in bringing forward this development. Any future phases of the development would further eat into the already identified green wedge.
* Dinas Powys is already oversubscribed for school places, and the medical facility is stretched, given it serves such a large area. The response provided in the Stakeholder Engagement report was that “A full assessment of local infrastructure, including schools and healthcare facilities, will be conducted to ensure the proposed scheme does not have any significant adverse impact on the overall function of key local services.” But this has not been provided in the supporting documentation"
* furthermore, the stakeholder engagement report summarises that the development has "general support"; these are based on biased questions i.e 'how important do you feel these aspects are', rather than an outright question of whether the development is supported.
* Note also that the feedback states that 75% of responders are neutral/negative when asked whether the scheme will meet local housing needs, and the feedback shows strongly that responders are not at all confident that the proposed development will mitigate the impacts on local traffic, in spite of the traffic assessment being one of the documents available in the consultation.

In addition to these three main areas of my objection, I would also like to raise the following

* the inclusion of this site, over and above other areas within the Vale of Glamorgan, shows a lack of support for levelling up growth. There is sufficient development in Cardiff and the surrounding areas, and spreading economic prosperity throughout the Vale, particularly in light of Welsh Government/Cardiff Capital Region support of developments such as Aberthaw, appears short-sighted
* there are numerous properties for sale within Dinas Powys, which have been on the market for months (years in some cases). This indicates that there is not the demand for housing in the area
* I am aware that this development has been previously promoted in the LDP and was not included, based on the traffic modelling undertaken. In my opinion, adequate justification has not been provided to overrule that decision.
* Persimmon clearly intend to develop the whole extent, and not just this first phase of development. The full development would completely change the character of the area through merging of Penarth, Llandough and Dinas Powys, and should not be allowed to proceed.

In summary, I believe that the porpoised development of Site HG1 KS2 – Land North of Dinas Powys is disproportionate to the capacity of the village, is not adequately considered through traffic modelling and does not follow best practice as set out in PPW12. As such, I respectfully request that Vale of Glamorgan Council reconsider the allocation of this site within the Replacement Local Development Plan.

As a resident of Dinas Powys, this submission focuses on Site Reference HG1 KS2 Land to the North of Dinas Powys. However, general comments around the RLDP should be considered in the whole.

My thoughts, concerns and objections are set out in the attached Annex and relate to 10 key areas.

Topics are not listed in priority order, they are all important, and I expect each to be given full consideration. For ease of reference the topics I will be referring to are:

Air Quality & Traffic
Flood Risk
Wastewater Treatment
Green Space & Green Infrastructure
Health & Wellbeing
Education & Medical Services
Affordable Housing Allocation
Community Cohesion & Social Integration
Climate Change & Sustainability
RLDP Plan-making Process & Evidence Base

1. Air Quality and Traffic
The RLDP has not been supported by a sufficiently robust, transparent and locally specific evidence base in relation to traffic capacity, mitigation, air quality and sustainable transport delivery in Dinas Powys.
The Plan relies on high-level assumptions rather than detailed assessments of known local constraints, and it does not provide adequate certainty that necessary mitigation and sustainable transport measures will be delivered, funded and implemented in a timely manner.
As a result, there is a significant risk that the cumulative impacts of development will lead to increased congestion, adverse effects on air quality and a deterioration in the quality of life for existing and future residents.
Until these evidence gaps are addressed and clear, enforceable measures are put in place, the RLDP cannot be considered fully justified, effective or consistent with national policy in its application to Dinas Powys.
Traffic Capacity
I am concerned that the RLDP has not demonstrated that the existing road network in Dinas Powys can cope with the scale of development proposed. Roads and junctions within the village already experience significant congestion both at peak times and throughout the day, particularly along Cardiff Road, St Andrew’s Road and the A4055.
The Plan does not provide clear or accessible evidence, such as detailed junction capacity assessments or peak-hour traffic modelling, to show that additional development will not worsen these problems. Without this information, I cannot be confident that growth can be accommodated without unacceptable impacts on daily travel, safety and quality of life.
Questions: Can the Council confirm that the existing highway network in Dinas Powys can accommodate the growth proposed in the RLDP without causing unacceptable congestion?
Can the Council provide evidence including junction capacity assessments and peak hour traffic modelling?

Mitigation Measures
Where development in Dinas Powys is likely to increase traffic, I am concerned that the RLDP does not clearly explain how congestion will be mitigated. Mitigation measures are described in general terms, but there is little clarity on what will actually be delivered, when it will happen, or who will pay for it. There is also no clear reassurance that mitigation will be in place before development takes place. I am concerned that traffic conditions could deteriorate further if development proceeds without effective safeguards.
Questions: For any development allocations in Dinas Powys that may impact congestion, what measures are proposed to mitigate these effects?
Are these measures fully funded, deliverable, and enforceable?
Air Quality Impacts
Increased traffic has clear implications for local air quality, particularly in residential areas and near schools and community facilities. I am concerned that the RLDP has not clearly assessed how the proposed growth in Dinas Powys will affect air quality, especially when the cumulative impact of multiple developments is considered.
The Plan does not explain how compliance with statutory air quality standards will be monitored or maintained as traffic levels increase. This creates significant uncertainty about potential impacts on public health and the local environment.
Questions: Has the Council assessed the likely impact of the proposed growth on local air quality in Dinas Powys, including cumulative effects?
How will the Plan ensure compliance with statutory air quality standards?
Sustainable Transport
While the RLDP refers to encouraging walking, cycling and public transport, I am not convinced that realistic alternatives to car/motor use will be delivered in Dinas Powys. There is limited detail on specific improvements, timescales or funding for sustainable transport. Without frequent, reliable public transport and safe, direct walking and cycling routes, it is unlikely that car use will reduce in practice. As a result, traffic growth and air quality impacts may be greater than the Plan assumes.
Question: How does the Plan/Council intend to ensure that sustainable travel options (walking, cycling, public transport) will be delivered and used to reduce traffic and air quality impacts in Dinas Powys?
Evidence Gaps
Overall, I am concerned that key evidence relating to traffic and air quality in Dinas Powys is either missing or insufficiently detailed. Without clear, locally specific assessments, it is difficult to understand how the Council can be confident that the Plan is sound or that its impacts on the community are acceptable.
Question: There are limitations in the transport and air quality evidence for Dinas Powys, how does the Council justify that the RLDP remains sound in light of these uncertainties?
 
2. Flood risk
I am concerned about the Replacement Local Development Plan (RLDP) and its impact on Dinas Powys, in relation to flood risk. Dinas Powys already experiences surface water flooding, overloaded drains and pressure on local watercourses. Any new development must be proven to be safe and must not make these problems worse. At present, the RLDP does not give me confidence that this has been properly addressed.
Flood Risk Has Not Been Properly Resolved
Welsh Government policy (TAN 15) says new development must be safe from flooding for its lifetime and that flood risk should be dealt with when the Plan is written, not later on. The RLDP appears to allocate sites that are affected by flood risk without clearly showing how they can be made safe. Instead, it relies on the idea that solutions will be worked out later when planning applications are submitted. As a resident, this is worrying, as there is no guarantee that those solutions will ever work or be delivered.
Questions: Can the Council explain how allocations within [or affecting] TAN 15 flood risk areas comply with TAN 15’s requirement that development be flood-safe for its lifetime, rather than relying on mitigation to be designed later?
Where the Plan relies on mitigation to address flood risk, what evidence demonstrates that such mitigation is deliverable, funded, and capable of implementation within the Plan period?
Is it the Council’s position that compliance with TAN 15 can be deferred to the planning application stage, and if so, how does that align with the requirement for strategic flood risk to be resolved at plan-making stage?

Lack of Clear Evidence Behind Flood Assessments
The flood studies supporting the Plan are not easy for a lay person to understand and do not clearly show that the full impact of new development has been properly assessed.
In particular, it is unclear whether:
• The combined effect of multiple new developments has been considered
• The worst-case impacts of climate change and heavier rainfall have been tested
• Flood risk to existing homes and streets has been fully taken into account
Without this information, it is hard to see how the Council can be confident that new development will not increase flooding in Dinas Powys.
Questions: What level of modelling underpins the SFCA, and can the Council confirm whether it assesses downstream and off-site impacts arising from cumulative development?
Does the SFCA test a ‘worst-case’ climate change scenario consistent with current Welsh Government guidance, and if not, why not?
How does the SFCA move beyond a desktop exercise to demonstrate that individual allocations are genuinely developable without increasing flood risk elsewhere?

Too Much Reliance on Future Drainage Solutions
The Plan relies heavily on Sustainable Drainage Systems (SuDS) to manage surface water, but there is little evidence showing that these systems can realistically work on all proposed sites.
I am concerned that:
• There may not be enough space on sites for effective drainage
• Water will still end up flowing into already stretched drains and streams
• Long-term maintenance of drainage systems is unclear
If these systems fail or are not properly maintained, flooding problems could become worse over time.
Questions: What evidence does the Plan rely on to show that SuDS can be accommodated on all relevant allocations without loss of developable area or displacement of flood risk?
Has the capacity of receiving watercourses and drainage networks been assessed at a strategic level, or is this assumed to be resolved site-by-site?
How does the Plan address the cumulative impact of multiple SuDS systems discharging into the same catchment?
What mechanisms are proposed to secure long-term maintenance of SuDS, and where is this evidenced in the Plan?

Doubts About Whether Sites Are Truly Deliverable
Some housing numbers in the Plan appear to depend on sites that may only work if major flood prevention measures are put in place, I believe that Dinas Powys is an example of this.
• It is not clear which sites depend on such measures
• There is no clear timetable or funding in place
• There is no backup plan if flood mitigation does not happen
I am concerned that the Plan may be relying on sites that cannot realistically be developed.
Question: Can the Council identify which allocations are dependent on flood mitigation infrastructure, and where the delivery, timing, and funding of that infrastructure are set out?
If mitigation fails to come forward, what contingency does the Plan provide to ensure housing delivery does not rely on undeliverable sites?
How does the Plan demonstrate that housing numbers are not inflated by sites whose flood risk constraints may ultimately prevent development?
Where NRW has expressed concerns or conditions relating to flood risk, how has the Council reflected those concerns in policy or allocations, rather than deferring them to later stages?
Has any NRW advice been departed from, and if so, what is the evidence base justifying that departure?

Climate Change and Long-Term Safety
Flooding is likely to become more frequent and severe due to climate change. The Plan does not clearly show that new development in or around Dinas Powys will remain safe for decades to come, not just during the Plan period.
Residents need reassurance that today’s decisions will not create long-term flooding problems for future generations.
Question: How does the Plan ensure resilience to increased rainfall intensity and flood frequency over the full lifetime of development, not just the Plan period itself?
Does the Plan assume future flood defences or upgrades, and if so, where are those projects committed and funded?
For these reasons, I believe the RLDP has not properly resolved flood risk issues affecting Dinas Powys, I ask that the Council be required to:
• Properly address flood risk at the plan-making stage, not later
• Remove or review sites where flood risk has not been clearly resolved
• Provide stronger evidence that new development will not increase flooding for existing residents.
Until this is done, the Plan cannot be considered sound.
 
3. Wastewater Treatment
This objection relates to the proposed level of housing growth in Dinas Powys and whether the existing wastewater and sewerage system can safely and realistically support it. I am concerned that the RLDP does not provide clear, settlement-specific evidence to show that wastewater treatment works and the local sewer network have enough capacity to accommodate the planned development, either now or within the Plan period. Without this evidence, the Plan risks placing unacceptable pressure on already constrained infrastructure, increasing the risk of flooding and environmental harm.
Wastewater Treatment Capacity
The RLDP does not clearly explain whether the wastewater treatment works serving Dinas Powys has sufficient spare capacity to deal with additional development.
In particular, the Plan does not set out:
• how much wastewater the treatment works is currently allowed to treat (its “consented capacity”),
• how much spare capacity is actually available,
• when this information was last assessed, or
• whether this assessment has been formally confirmed by Dŵr Cymru Welsh Water.
Without this basic information, I lack sufficient information to understand whether the existing system is already close to capacity or whether it genuinely has room to cope with new development.
The Plan also does not clearly state how much additional wastewater would be generated by the new housing proposed for Dinas Powys, or how this compares with any available capacity. This makes it impossible to judge whether the level of growth proposed is realistic.
There is no clear evidence that a Dinas Powys–specific assessment has been carried out. If the Council is relying on broad, county-wide modelling instead, this does not reflect local conditions or known issues within the village.

Sewer Network Constraints & Flood Risk
Many residents are already aware of problems with drainage, surface water, and sewer performance in Dinas Powys, particularly during periods of heavy rainfall.
However, the RLDP does not provide clear evidence on:
• existing sewer surcharging or flooding incidents,
• past or current problems with overloaded sewers,
storm overflow activity affecting the area.
There is also no clear explanation of how the combined impact of multiple new development sites in Dinas Powys has been assessed together, rather than individually. This is especially concerning given the increasing frequency of intense rainfall linked to climate change.
Dinas Powys has known surface water and flood risk sensitivities, yet the Plan does not convincingly demonstrate that increased wastewater flows will not make flooding worse or lead to pollution of local watercourses.
I am concerned that problems will only become apparent after development has already taken place.

Deliverability & Infrastructure Planning
The RLDP does not identify any specific wastewater or sewerage upgrades needed to support the proposed growth in Dinas Powys.
Where upgrades may be required, the Plan does not explain:
• what infrastructure improvements would be needed,
• how much they would cost,
• who would pay for them, or
• when they would be delivered.
This creates significant uncertainty. I am concerned that development could go ahead before infrastructure is in place, leaving existing communities to deal with the consequences of overloaded systems.
There is also no clear explanation of how infrastructure will be phased to ensure that wastewater capacity is available before new homes are occupied, rather than relying on solutions being found later.

Role of the Statutory Undertaker – Dŵr Cymru Welsh Water
The Plan appears to rely heavily on future discussions with Dŵr Cymru Welsh Water at the planning application stage to resolve wastewater issues. I am concerned that this approach puts off important decisions that should be made now, during the Plan-making process. National planning policy requires development plans to be based on a clear understanding of infrastructure capacity, not assumptions that problems can be fixed later. Without clear, written confirmation from Dŵr Cymru Welsh Water that the proposed level of growth in Dinas Powys can be accommodated, I believe the Plan lacks the certainty needed to be considered sound.

Soundness & Policy Compliance
Because the RLDP does not clearly demonstrate that wastewater infrastructure:
• is available,
• can be upgraded in time, and
• has a realistic and funded delivery plan,
I do not believe the Plan is effective, which is a key test of soundness. The Plan also appears to conflict with Planning Policy Wales, which states that development should be directed to locations where infrastructure is already in place or can be secured. Deferring wastewater solutions to a later stage does not meet this requirement.
If wastewater capacity problems cannot be resolved within the Plan period, I question why the level of development proposed for Dinas Powys has not been reduced to reflect real infrastructure constraints.
 
4. Green Space & Green Infrastructure
For the reasons set out below I consider that the RLDP is unsound in relation to green space and green infrastructure in Dinas Powys because it:
• Fails to justify the loss of existing green space or show that mitigation will be delivered;
• Lacks clear evidence on the quantity, quality, and accessibility of green space;
• Does not safeguard the integrity of green infrastructure networks;
• Provides no mechanisms to ensure timely delivery of green space alongside new development;
• Does not demonstrate that alternatives were properly considered through the Sustainability Appraisal.
Until these issues are addressed, there is no clear basis to conclude that the proposed growth in Dinas Powys can be accommodated without unacceptable impacts on local green spaces and the wider environment. I urge the Council to carefully consider these concerns and provide further evidence or modifications to ensure that the Plan is effective, sustainable, and compliant with national planning policy
Protection of Existing Green Space
The RLDP does not clearly explain why any existing green spaces in Dinas Powys might be lost, or whether the loss is unavoidable.
I am concerned that the Plan does not demonstrate:
• that all alternatives to protect existing green space have been considered, or
• that any replacement or mitigation will be provided within or near the village.
Without this evidence, there is no assurance that valued local green spaces, which are important for recreation, biodiversity, and the character of the settlement, will be preserved. This is a serious omission that makes the Plan unsound in this respect.
Question: How does the Plan justify the loss of any existing green spaces in Dinas Powys? Has an assessment been carried out demonstrating that loss is unavoidable, and that adequate replacement or mitigation will be provided within or near the settlement?
Quantity, Quality, and Accessibility of Green Space
The RLDP does not provide clear, settlement-specific information about the amount, quality, or accessibility of green space for Dinas Powys residents.
It is unclear whether the standards being applied:
• meet national policy requirements,
• reflect the needs of the local population, or
• will be sufficient to support an increased population from new housing.
Without clear evidence, I cannot be confident that new development will maintain adequate recreational and amenity space for all residents.
Question: What evidence supports the quantity, quality, and accessibility standards for green space in Dinas Powys? How do these standards compare with national policy and the needs of the local population?

Green Infrastructure Network Integrity
The Plan does not explain how green infrastructure networks—including wildlife corridors, footpaths, cycleways, and recreational routes—will remain coherent and functional as new development comes forward.
There is a real risk that the proposed growth could fragment these networks, reducing connectivity for wildlife and limiting access to recreational spaces. I am concerned that the Plan does not set out measures to prevent these negative impacts.
• Question: How does the Plan ensure that green infrastructure networks in Dinas Powys, including wildlife corridors, footpaths, and recreational routes, remain coherent and functional despite new development?

Delivery and Implementation
The RLDP does not make it clear how green space provision will be delivered at the same time as development, rather than being left to later planning agreements or discretionary decisions.
Without clear delivery mechanisms, there is no certainty that new or replacement green space will be provided when needed. This creates risk that residents will face reduced access to recreation, wildlife habitats, and open space for years after new homes are built.
• Question: What mechanisms are in place to ensure that green space provision in Dinas Powys will be delivered alongside development, rather than deferred to later discretionary planning stages?

Consideration in the Sustainability Appraisal
It is not evident that the Plan’s Sustainability Appraisal has fully assessed the impact of proposed development on green space and green infrastructure in Dinas Powys.
There is no clear explanation of whether alternative development options were considered that would reduce the loss or fragmentation of green spaces, and if so, why these alternatives were rejected. I am concerned that the lack of settlement-specific analysis weakens the credibility of the Plan and its ability to safeguard local environmental assets.
Question: Has the Integrated Sustainability Appraisal fully considered the impacts of proposed development on green space and green infrastructure in Dinas Powys? Were alternatives considered that would reduce loss or fragmentation, and if so, why were they rejected?
 
5. Health & Wellbeing
Alignment with RLDP Policy SP6
The RLDP does not clearly demonstrate how proposed allocations and policies affecting Dinas Powys will achieve the health and well-being objectives set out in Policy SP6.
In particular, the Plan does not provide evidence that new development will:
• maintain or enhance access to green spaces,
• support active travel (walking, cycling, public transport), or
• deliver inclusive and safe public environments for all residents.
Without clear mechanisms to ensure these outcomes, it is unclear how the Plan will contribute to the creation of healthy, inclusive communities in line with its own strategic policy.
Question: How does the Plan ensure that proposed allocations and policies affecting Dinas Powys will deliver the health and well-being objectives set out in Policy SP6, including access to green space, active travel, and inclusive public environments?

Alignment with the Vale of Glamorgan Well-Being Plan
The RLDP does not clearly show how its proposals for Dinas Powys are consistent with the objectives of the Vale of Glamorgan Public Services Board Well-Being Plan, particularly in relation to:
• physical and mental health,
• health equity, and
• equitable access to green and recreational spaces.
There is no settlement-specific evidence demonstrating that new housing or other allocations will support these well-being objectives, leaving a gap in the Plan’s justification and effectiveness.
Question: How does the RLDP demonstrate consistency with the Vale of Glamorgan Public Services Board Well-Being Plan, particularly the objectives relating to physical and mental health, health equity, and access to green spaces in Dinas Powys?

Evidence for Health and Well-Being Outcomes
The Plan does not provide sufficient evidence that its spatial strategy, site allocations, or policies will produce measurable improvements in health outcomes for residents of Dinas Powys, particularly in areas where health needs are identified. Without this evidence, it is impossible to determine whether the proposed development will genuinely support improved physical or mental health, reduce health inequalities, or provide accessible, high-quality spaces for recreation and social interaction.
Question: What evidence demonstrates that the Plan’s spatial strategy, allocations, and policies in Dinas Powys will produce measurable improvements in health outcomes for residents, especially in areas of identified need?

Integration with the Sustainability Appraisal
The RLDP’s Integrated Sustainability Appraisal (ISA) does not clearly demonstrate how health and well-being impacts have been addressed specifically for Dinas Powys.
There is limited information on:
• mitigation or enhancement measures to support healthy communities,
• the contribution of proposed allocations to active travel networks, or
• ways in which new development will improve access to green infrastructure or inclusive public spaces.
Without settlement-specific consideration, the ISA does not provide sufficient assurance that health and well-being outcomes will be achieved, nor does it demonstrate compliance with national planning policy on creating healthy and sustainable places.
Question: How has the Integrated Sustainability Appraisal addressed health and well-being impacts specifically for Dinas Powys, and what mitigation or enhancement measures are proposed to ensure alignment with national planning policy on healthy places?
 
6. Education & Medical Services
I believe that the RLDP is unsound in relation to education and healthcare services in Dinas Powys

Education Provision
The RLDP does not provide clear, settlement-specific evidence regarding school capacity in Dinas Powys.
My key concerns include:
• There is no demonstration that local primary and secondary schools have enough places for the children who will arise from the proposed housing.
• It is unclear whether the Plan relies on borough-wide estimates, which may overlook local pressures and result in shortages at specific schools.
• The Plan does not identify any specific improvements to school infrastructure (such as new classrooms, extensions, or new schools), nor does it set out funding, timing, or delivery mechanisms.
Without these assurances, there is no certainty that school places will be available before families move in, which could lead to overcrowding and diminished educational standards. I am concerned that, in the absence of firm evidence and infrastructure commitments, the proposed scale of housing growth in Dinas Powys may be unsustainable and undeliverable.

Healthcare / Medical Services
The RLDP does not demonstrate that local healthcare services—including GP practices, dental services, and community health facilities—can accommodate the increased population.
My specific concerns include:
• There is no settlement-specific assessment of current or future healthcare capacity in Dinas Powys.
• The Plan does not indicate whether additional or expanded healthcare facilities will be provided, nor how this would be funded, phased, or secured alongside new housing.
• Without clear planning, the proposed growth could reduce access to essential health services for both existing and new residents, impacting physical and mental health outcomes.
I am particularly concerned that increased demand without confirmed provision could lead to longer waiting times, reduced appointments, and pressure on local medical staff, undermining the well-being of the community. These gaps mean the Plan is not effective, justified, or consistent with national planning policy, which requires growth to be planned where infrastructure is available or can be secured.

7. Affordable Housing Allocation
I support the principle of providing affordable homes for local residents, especially young families, first-time buyers, and key workers who cannot afford market rates.
Well-planned affordable housing can help maintain a mixed and vibrant community and retain younger residents. Affordable homes in Dinas Powys could reduce commuting pressures by allowing residents to live and work locally. However, the RLDP does not provide clear evidence for how many affordable homes are needed in Dinas Powys or what types of homes are required for different groups (families, older residents, low-income households). There is insufficient information about how and when affordable homes will actually be delivered alongside market housing. Without clear delivery plans or safeguards, affordable homes may not remain genuinely affordable in the long term. Concentrated or poorly planned affordable housing may put pressure on local schools, healthcare, transport, and green spaces, which are already constrained in Dinas Powys. The Plan does not explain how affordable housing will be integrated with market housing to create sustainable, mixed communities rather than segregation or social imbalance. Because of the lack of clear evidence, delivery mechanisms, and mitigation for potential negative impacts, I do not consider the Plan sound in terms of affordable housing in Dinas Powys.
 
8. Community Cohesion & Social Integration
I am concerned that the Plan, as currently drafted, does not ensure new growth will support strong, healthy, and inclusive communities. Until the Council provides clear evidence and enforceable measures addressing community cohesion, housing mix, and health impacts, I cannot have confidence that the Plan is sustainable or fair.
Impact on Community Cohesion and Social Integration
I am concerned that the Plan does not explain how new housing and growth will integrate with existing communities. There is a risk that rapid development could strain local services, schools, and community spaces, and make it harder for neighbours to get to know one another.
I would like to see evidence that social infrastructure will keep pace with population growth and that communities will remain inclusive and connected.

Risk of Over-Concentration of Affordable Housing
I am concerned that clusters of affordable housing in certain areas could lead to pockets of social exclusion or limit access to opportunities. The Plan does not explain how it will ensure a good mix of housing types and tenures across the Vale. I ask that the Council provide evidence that housing allocations will support socially balanced, inclusive communities.

Impacts on Mental and Physical Wellbeing
I am concerned about increased traffic, air pollution, noise, and the loss of green spaces affecting health and wellbeing. The Plan does not provide clear commitments to protect or improve accessible green spaces or safe walking and cycling routes. I would like to see evidence that the Plan has assessed the health impacts of growth and will take steps to mitigate them.
 
9. Climate Change & Sustainability
I am concerned that, as drafted, the Plan does not provide enough evidence or practical measures to ensure new development is sustainable and climate resilient. The RLDP is not fully justified, effective, or consistent with national policy on climate change and sustainability. Key gaps include alignment with carbon reduction targets, enforceable delivery of low-carbon travel, energy-efficient homes, sustainable drainage, and climate-resilient infrastructure. Without clear policies and enforceable commitments on low-carbon travel, energy-efficient homes, sustainable drainage, and climate-resilient infrastructure, the Plan risks harming both the environment and the wellbeing of communities.

Alignment with Welsh Government’s Carbon Reduction Targets
I am concerned that the Plan does not explain clearly how new homes, workplaces, and other development will help Wales meet its legally binding carbon reduction targets.
Without this, there is a risk that growth in the Vale could increase emissions rather than reduce them. I would like to see evidence showing how this (and each) new development contributes to lowering carbon emissions.

Promotion of Low-Carbon Travel, Energy-Efficient Homes, and Sustainable Drainage
I am worried that the Plan relies too much on people walking, cycling, or using public transport without clear plans to make this happen. There is also little information on whether new homes will be energy-efficient or if systems to manage rainfall and reduce flooding (like sustainable drainage) will be properly installed and maintained. I want to see clear, practical measures to make low-carbon travel, energy-efficient homes, and safe drainage a reality.

Resilience of Infrastructure to Extreme Weather Events
I am very concerned about the impacts of extreme weather, including flooding, heatwaves, and storms, on roads, utilities, and homes. The Plan does not clearly show how new developments or existing infrastructure will be designed to cope with these risks. I would like to have assurance that any buildings, roads, drainage, and community facilities will be climate-resilient and protect people’s health and safety.
 
10. Plan-making Process & Evidence Base
In my view, the RLDP is not fully justified or effective in its current form with respect to plan-making and the evidence base. Key gaps include accessibility and transparency of evidence, consideration of resident and stakeholder feedback, and robust monitoring and review arrangements. Without clear and accessible evidence, demonstrated consideration of local feedback, and robust monitoring and review mechanisms, residents cannot be confident that the Plan will be fair, effective, or responsive to changing circumstances.

Clarity, Transparency, and Accessibility of Evidence
The RLDP is not always clear and is not easy to access.
Technical reports, data, and assumptions are often difficult to find or understand, making it hard for residents to see why particular sites or policies were chosen. The Council should provide accessible summaries and clear explanations so that everyone can understand and comment on the evidence.

Local Consultation and Consideration of Resident Feedback
I am concerned that residents’ views may not have been fully taken into account in shaping the Plan. It is unclear how consultation responses have influenced allocation decisions or policy wording. I seek assurance that feedback from local people and community groups has genuinely informed the Plan, and that future consultations will be inclusive and clearly reported.

Monitoring and Review Mechanisms
The Plan does not clearly explain how progress will be monitored or how changes will be made if things do not go as planned. For example, if housing delivery is slower than expected or infrastructure is delayed, there is little information on how allocations or policies would be adjusted.

As a resident of Dinas Powys, this submission focuses on Site Reference HG1 KS2 Land to the North of Dinas Powys. However, general comments around the RLDP should be considered in the whole. My thoughts, concerns and objections are set out in the attached Annex and relate to 10 key areas.
Topics are not listed in priority order, they are all important, and I expect each to be given full consideration. For ease of reference the topics I will be referring to are:
Air Quality & Traffic
Flood Risk
Wastewater Treatment
Green Space & Green Infrastructure
Health & Wellbeing
Education & Medical Services
Affordable Housing Allocation
Community Cohesion & Social Integration
Climate Change & Sustainability
RLDP Plan-making Process & Evidence Base

1. Air Quality and Traffic
The RLDP has not been supported by a sufficiently robust, transparent and locally specific evidence base in relation to traffic capacity, mitigation, air quality and sustainable transport delivery in Dinas Powys. The Plan relies on high-level assumptions rather than detailed assessments of known local constraints, and it does not provide adequate certainty that necessary mitigation and sustainable transport measures will be delivered, funded and implemented in a timely manner. As a result, there is a significant risk that the cumulative impacts of development will lead to increased congestion, adverse effects on air quality and a deterioration in the quality of life for existing and future residents. Until these evidence gaps are addressed and clear, enforceable measures are put in place, the RLDP cannot be considered fully justified, effective or consistent with national policy in its application to Dinas Powys.
Traffic Capacity
I am concerned that the RLDP has not demonstrated that the existing road network in Dinas Powys can cope with the scale of development proposed. Roads and junctions within the village already experience significant congestion both at peak times and throughout the day, particularly along Cardiff Road, St Andrew’s Road and the A4055.
The Plan does not provide clear or accessible evidence, such as detailed junction capacity assessments or peak-hour traffic modelling, to show that additional development will not worsen these problems. Without this information, I cannot be confident that growth can be accommodated without unacceptable impacts on daily travel, safety and quality of life.
Questions: Can the Council confirm that the existing highway network in Dinas Powys can accommodate the growth proposed in the RLDP without causing unacceptable congestion?
Can the Council provide evidence including junction capacity assessments and peak hour traffic modelling?
Mitigation Measures
Where development in Dinas Powys is likely to increase traffic, I am concerned that the RLDP does not clearly explain how congestion will be mitigated. Mitigation measures are described in general terms, but there is little clarity on what will actually be delivered, when it will happen, or who will pay for it. There is also no clear reassurance that mitigation will be in place before development takes place. I am concerned that traffic conditions could deteriorate further if development proceeds without effective safeguards.
Questions: For any development allocations in Dinas Powys that may impact congestion, what measures are proposed to mitigate these effects?
Are these measures fully funded, deliverable, and enforceable?
Air Quality Impacts
Increased traffic has clear implications for local air quality, particularly in residential areas and near schools and community facilities. I am concerned that the RLDP has not clearly assessed how the proposed growth in Dinas Powys will affect air quality, especially when the cumulative impact of multiple developments is considered.
The Plan does not explain how compliance with statutory air quality standards will be monitored or maintained as traffic levels increase. This creates significant uncertainty about potential impacts on public health and the local environment.
Questions: Has the Council assessed the likely impact of the proposed growth on local air quality in Dinas Powys, including cumulative effects?
How will the Plan ensure compliance with statutory air quality standards?
Sustainable Transport
While the RLDP refers to encouraging walking, cycling and public transport, I am not convinced that realistic alternatives to car/motor use will be delivered in Dinas Powys. There is limited detail on specific improvements, timescales or funding for sustainable transport. Without frequent, reliable public transport and safe, direct walking and cycling routes, it is unlikely that car use will reduce in practice. As a result, traffic growth and air quality impacts may be greater than the Plan assumes.
Question: How does the Plan/Council intend to ensure that sustainable travel options (walking, cycling, public transport) will be delivered and used to reduce traffic and air quality impacts in Dinas Powys?
Evidence Gaps
Overall, I am concerned that key evidence relating to traffic and air quality in Dinas Powys is either missing or insufficiently detailed. Without clear, locally specific assessments, it is difficult to understand how the Council can be confident that the Plan is sound or that its impacts on the community are acceptable.
Question: There are limitations in the transport and air quality evidence for Dinas Powys, how does the Council justify that the RLDP remains sound in light of these uncertainties?
 
2. Flood risk
I am concerned about the Replacement Local Development Plan (RLDP) and its impact on Dinas Powys, in relation to flood risk. Dinas Powys already experiences surface water flooding, overloaded drains and pressure on local watercourses. Any new development must be proven to be safe and must not make these problems worse. At present, the RLDP does not give me confidence that this has been properly addressed.
Flood Risk Has Not Been Properly Resolved
Welsh Government policy (TAN 15) says new development must be safe from flooding for its lifetime and that flood risk should be dealt with when the Plan is written, not later on. The RLDP appears to allocate sites that are affected by flood risk without clearly showing how they can be made safe. Instead, it relies on the idea that solutions will be worked out later when planning applications are submitted. As a resident, this is worrying, as there is no guarantee that those solutions will ever work or be delivered.
Questions: Can the Council explain how allocations within [or affecting] TAN 15 flood risk areas comply with TAN 15’s requirement that development be flood-safe for its lifetime, rather than relying on mitigation to be designed later?
Where the Plan relies on mitigation to address flood risk, what evidence demonstrates that such mitigation is deliverable, funded, and capable of implementation within the Plan period?
Is it the Council’s position that compliance with TAN 15 can be deferred to the planning application stage, and if so, how does that align with the requirement for strategic flood risk to be resolved at plan-making stage?
Lack of Clear Evidence Behind Flood Assessments
The flood studies supporting the Plan are not easy for a lay person to understand and do not clearly show that the full impact of new development has been properly assessed. In particular, it is unclear whether:
• The combined effect of multiple new developments has been considered
• The worst-case impacts of climate change and heavier rainfall have been tested
• Flood risk to existing homes and streets has been fully taken into account
Without this information, it is hard to see how the Council can be confident that new development will not increase flooding in Dinas Powys.
Questions: What level of modelling underpins the SFCA, and can the Council confirm whether it assesses downstream and off-site impacts arising from cumulative development?
Does the SFCA test a ‘worst-case’ climate change scenario consistent with current Welsh Government guidance, and if not, why not?
How does the SFCA move beyond a desktop exercise to demonstrate that individual allocations are genuinely developable without increasing flood risk elsewhere?
Too Much Reliance on Future Drainage Solutions
The Plan relies heavily on Sustainable Drainage Systems (SuDS) to manage surface water, but there is little evidence showing that these systems can realistically work on all proposed sites.
I am concerned that:
• There may not be enough space on sites for effective drainage
• Water will still end up flowing into already stretched drains and streams
• Long-term maintenance of drainage systems is unclear
If these systems fail or are not properly maintained, flooding problems could become worse over time.
Questions: What evidence does the Plan rely on to show that SuDS can be accommodated on all relevant allocations without loss of developable area or displacement of flood risk?
Has the capacity of receiving watercourses and drainage networks been assessed at a strategic level, or is this assumed to be resolved site-by-site?
How does the Plan address the cumulative impact of multiple SuDS systems discharging into the same catchment?
What mechanisms are proposed to secure long-term maintenance of SuDS, and where is this evidenced in the Plan?
Doubts About Whether Sites Are Truly Deliverable
Some housing numbers in the Plan appear to depend on sites that may only work if major flood prevention measures are put in place, I believe that Dinas Powys is an example of this.
• It is not clear which sites depend on such measures
• There is no clear timetable or funding in place
• There is no backup plan if flood mitigation does not happen
I am concerned that the Plan may be relying on sites that cannot realistically be developed.
Question: Can the Council identify which allocations are dependent on flood mitigation infrastructure, and where the delivery, timing, and funding of that infrastructure are set out?
If mitigation fails to come forward, what contingency does the Plan provide to ensure housing delivery does not rely on undeliverable sites?
How does the Plan demonstrate that housing numbers are not inflated by sites whose flood risk constraints may ultimately prevent development?
Where NRW has expressed concerns or conditions relating to flood risk, how has the Council reflected those concerns in policy or allocations, rather than deferring them to later stages?
Has any NRW advice been departed from, and if so, what is the evidence base justifying that departure?
Climate Change and Long-Term Safety
Flooding is likely to become more frequent and severe due to climate change. The Plan does not clearly show that new development in or around Dinas Powys will remain safe for decades to come, not just during the Plan period.
Residents need reassurance that today’s decisions will not create long-term flooding problems for future generations.
Question: How does the Plan ensure resilience to increased rainfall intensity and flood frequency over the full lifetime of development, not just the Plan period itself?
Does the Plan assume future flood defences or upgrades, and if so, where are those projects committed and funded?
For these reasons, I believe the RLDP has not properly resolved flood risk issues affecting Dinas Powys, I ask that the Council be required to:
• Properly address flood risk at the plan-making stage, not later
• Remove or review sites where flood risk has not been clearly resolved
• Provide stronger evidence that new development will not increase flooding for existing residents.
Until this is done, the Plan cannot be considered sound.
 
3. Wastewater Treatment
This objection relates to the proposed level of housing growth in Dinas Powys and whether the existing wastewater and sewerage system can safely and realistically support it. I am concerned that the RLDP does not provide clear, settlement-specific evidence to show that wastewater treatment works and the local sewer network have enough capacity to accommodate the planned development, either now or within the Plan period. Without this evidence, the Plan risks placing unacceptable pressure on already constrained infrastructure, increasing the risk of flooding and environmental harm.
Wastewater Treatment Capacity
The RLDP does not clearly explain whether the wastewater treatment works serving Dinas Powys has sufficient spare capacity to deal with additional development. In particular, the Plan does not set out:
• how much wastewater the treatment works is currently allowed to treat (its “consented capacity”),
• how much spare capacity is actually available,
• when this information was last assessed, or
• whether this assessment has been formally confirmed by Dŵr Cymru Welsh Water.
Without this basic information, I lack sufficient information to understand whether the existing system is already close to capacity or whether it genuinely has room to cope with new development. The Plan also does not clearly state how much additional wastewater would be generated by the new housing proposed for Dinas Powys, or how this compares with any available capacity. This makes it impossible to judge whether the level of growth proposed is realistic. There is no clear evidence that a Dinas Powys–specific assessment has been carried out. If the Council is relying on broad, county-wide modelling instead, this does not reflect local conditions or known issues within the village.
Sewer Network Constraints & Flood Risk
Many residents are already aware of problems with drainage, surface water, and sewer performance in Dinas Powys, particularly during periods of heavy rainfall.
However, the RLDP does not provide clear evidence on:
• existing sewer surcharging or flooding incidents,
• past or current problems with overloaded sewers,
storm overflow activity affecting the area.
There is also no clear explanation of how the combined impact of multiple new development sites in Dinas Powys has been assessed together, rather than individually. This is especially concerning given the increasing frequency of intense rainfall linked to climate change.
Dinas Powys has known surface water and flood risk sensitivities, yet the Plan does not convincingly demonstrate that increased wastewater flows will not make flooding worse or lead to pollution of local watercourses.
I am concerned that problems will only become apparent after development has already taken place.
Deliverability & Infrastructure Planning
The RLDP does not identify any specific wastewater or sewerage upgrades needed to support the proposed growth in Dinas Powys. Where upgrades may be required, the Plan does not explain:
• what infrastructure improvements would be needed,
• how much they would cost,
• who would pay for them, or
• when they would be delivered.
This creates significant uncertainty. I am concerned that development could go ahead before infrastructure is in place, leaving existing communities to deal with the consequences of overloaded systems.
There is also no clear explanation of how infrastructure will be phased to ensure that wastewater capacity is available before new homes are occupied, rather than relying on solutions being found later.
Role of the Statutory Undertaker – Dŵr Cymru Welsh Water
The Plan appears to rely heavily on future discussions with Dŵr Cymru Welsh Water at the planning application stage to resolve wastewater issues. I am concerned that this approach puts off important decisions that should be made now, during the Plan-making process. National planning policy requires development plans to be based on a clear understanding of infrastructure capacity, not assumptions that problems can be fixed later. Without clear, written confirmation from Dŵr Cymru Welsh Water that the proposed level of growth in Dinas Powys can be accommodated, I believe the Plan lacks the certainty needed to be considered sound.
Soundness & Policy Compliance
Because the RLDP does not clearly demonstrate that wastewater infrastructure:
• is available,
• can be upgraded in time, and
• has a realistic and funded delivery plan,
I do not believe the Plan is effective, which is a key test of soundness. The Plan also appears to conflict with Planning Policy Wales, which states that development should be directed to locations where infrastructure is already in place or can be secured. Deferring wastewater solutions to a later stage does not meet this requirement.
If wastewater capacity problems cannot be resolved within the Plan period, I question why the level of development proposed for Dinas Powys has not been reduced to reflect real infrastructure constraints.
 
4. Green Space & Green Infrastructure
For the reasons set out below I consider that the RLDP is unsound in relation to green space and green infrastructure in Dinas Powys because it:
• Fails to justify the loss of existing green space or show that mitigation will be delivered;
• Lacks clear evidence on the quantity, quality, and accessibility of green space;
• Does not safeguard the integrity of green infrastructure networks;
• Provides no mechanisms to ensure timely delivery of green space alongside new development;
• Does not demonstrate that alternatives were properly considered through the Sustainability Appraisal.
Until these issues are addressed, there is no clear basis to conclude that the proposed growth in Dinas Powys can be accommodated without unacceptable impacts on local green spaces and the wider environment. I urge the Council to carefully consider these concerns and provide further evidence or modifications to ensure that the Plan is effective, sustainable, and compliant with national planning policy
Protection of Existing Green Space
The RLDP does not clearly explain why any existing green spaces in Dinas Powys might be lost, or whether the loss is unavoidable. I am concerned that the Plan does not demonstrate:
• that all alternatives to protect existing green space have been considered, or
• that any replacement or mitigation will be provided within or near the village.
Without this evidence, there is no assurance that valued local green spaces, which are important for recreation, biodiversity, and the character of the settlement, will be preserved. This is a serious omission that makes the Plan unsound in this respect.
Question: How does the Plan justify the loss of any existing green spaces in Dinas Powys? Has an assessment been carried out demonstrating that loss is unavoidable, and that adequate replacement or mitigation will be provided within or near the settlement?
Quantity, Quality, and Accessibility of Green Space
The RLDP does not provide clear, settlement-specific information about the amount, quality, or accessibility of green space for Dinas Powys residents. It is unclear whether the standards being applied:
• meet national policy requirements,
• reflect the needs of the local population, or
• will be sufficient to support an increased population from new housing.
Without clear evidence, I cannot be confident that new development will maintain adequate recreational and amenity space for all residents.
Question: What evidence supports the quantity, quality, and accessibility standards for green space in Dinas Powys? How do these standards compare with national policy and the needs of the local population?
Green Infrastructure Network Integrity
The Plan does not explain how green infrastructure networks—including wildlife corridors, footpaths, cycleways, and recreational routes—will remain coherent and functional as new development comes forward.
There is a real risk that the proposed growth could fragment these networks, reducing connectivity for wildlife and limiting access to recreational spaces. I am concerned that the Plan does not set out measures to prevent these negative impacts.
• Question: How does the Plan ensure that green infrastructure networks in Dinas Powys, including wildlife corridors, footpaths, and recreational routes, remain coherent and functional despite new development?
Delivery and Implementation
The RLDP does not make it clear how green space provision will be delivered at the same time as development, rather than being left to later planning agreements or discretionary decisions.
Without clear delivery mechanisms, there is no certainty that new or replacement green space will be provided when needed. This creates risk that residents will face reduced access to recreation, wildlife habitats, and open space for years after new homes are built.
• Question: What mechanisms are in place to ensure that green space provision in Dinas Powys will be delivered alongside development, rather than deferred to later discretionary planning stages?
Consideration in the Sustainability Appraisal
It is not evident that the Plan’s Sustainability Appraisal has fully assessed the impact of proposed development on green space and green infrastructure in Dinas Powys.
There is no clear explanation of whether alternative development options were considered that would reduce the loss or fragmentation of green spaces, and if so, why these alternatives were rejected. I am concerned that the lack of settlement-specific analysis weakens the credibility of the Plan and its ability to safeguard local environmental assets.
Question: Has the Integrated Sustainability Appraisal fully considered the impacts of proposed development on green space and green infrastructure in Dinas Powys? Were alternatives considered that would reduce loss or fragmentation, and if so, why were they rejected?
 
5. Health & Wellbeing
Alignment with RLDP Policy SP6
The RLDP does not clearly demonstrate how proposed allocations and policies affecting Dinas Powys will achieve the health and well-being objectives set out in Policy SP6.
In particular, the Plan does not provide evidence that new development will:
• maintain or enhance access to green spaces,
• support active travel (walking, cycling, public transport), or
• deliver inclusive and safe public environments for all residents.
Without clear mechanisms to ensure these outcomes, it is unclear how the Plan will contribute to the creation of healthy, inclusive communities in line with its own strategic policy.
Question: How does the Plan ensure that proposed allocations and policies affecting Dinas Powys will deliver the health and well-being objectives set out in Policy SP6, including access to green space, active travel, and inclusive public environments?
Alignment with the Vale of Glamorgan Well-Being Plan
The RLDP does not clearly show how its proposals for Dinas Powys are consistent with the objectives of the Vale of Glamorgan Public Services Board Well-Being Plan, particularly in relation to:
• physical and mental health,
• health equity, and
• equitable access to green and recreational spaces.
There is no settlement-specific evidence demonstrating that new housing or other allocations will support these well-being objectives, leaving a gap in the Plan’s justification and effectiveness.
Question: How does the RLDP demonstrate consistency with the Vale of Glamorgan Public Services Board Well-Being Plan, particularly the objectives relating to physical and mental health, health equity, and access to green spaces in Dinas Powys?
Evidence for Health and Well-Being Outcomes
The Plan does not provide sufficient evidence that its spatial strategy, site allocations, or policies will produce measurable improvements in health outcomes for residents of Dinas Powys, particularly in areas where health needs are identified.
Without this evidence, it is impossible to determine whether the proposed development will genuinely support improved physical or mental health, reduce health inequalities, or provide accessible, high-quality spaces for recreation and social interaction.
Question: What evidence demonstrates that the Plan’s spatial strategy, allocations, and policies in Dinas Powys will produce measurable improvements in health outcomes for residents, especially in areas of identified need?
Integration with the Sustainability Appraisal
The RLDP’s Integrated Sustainability Appraisal (ISA) does not clearly demonstrate how health and well-being impacts have been addressed specifically for Dinas Powys.
There is limited information on:
• mitigation or enhancement measures to support healthy communities,
• the contribution of proposed allocations to active travel networks, or
• ways in which new development will improve access to green infrastructure or inclusive public spaces.
Without settlement-specific consideration, the ISA does not provide sufficient assurance that health and well-being outcomes will be achieved, nor does it demonstrate compliance with national planning policy on creating healthy and sustainable places.
Question: How has the Integrated Sustainability Appraisal addressed health and well-being impacts specifically for Dinas Powys, and what mitigation or enhancement measures are proposed to ensure alignment with national planning policy on healthy places?
 
6. Education & Medical Services
I believe that the RLDP is unsound in relation to education and healthcare services in Dinas Powys
Education Provision
The RLDP does not provide clear, settlement-specific evidence regarding school capacity in Dinas Powys.
My key concerns include:
• There is no demonstration that local primary and secondary schools have enough places for the children who will arise from the proposed housing.
• It is unclear whether the Plan relies on borough-wide estimates, which may overlook local pressures and result in shortages at specific schools.
• The Plan does not identify any specific improvements to school infrastructure (such as new classrooms, extensions, or new schools), nor does it set out funding, timing, or delivery mechanisms.
Without these assurances, there is no certainty that school places will be available before families move in, which could lead to overcrowding and diminished educational standards. I am concerned that, in the absence of firm evidence and infrastructure commitments, the proposed scale of housing growth in Dinas Powys may be unsustainable and undeliverable.
Healthcare / Medical Services
The RLDP does not demonstrate that local healthcare services—including GP practices, dental services, and community health facilities—can accommodate the increased population.
My specific concerns include:
• There is no settlement-specific assessment of current or future healthcare capacity in Dinas Powys.
• The Plan does not indicate whether additional or expanded healthcare facilities will be provided, nor how this would be funded, phased, or secured alongside new housing.
• Without clear planning, the proposed growth could reduce access to essential health services for both existing and new residents, impacting physical and mental health outcomes.
I am particularly concerned that increased demand without confirmed provision could lead to longer waiting times, reduced appointments, and pressure on local medical staff, undermining the well-being of the community. These gaps mean the Plan is not effective, justified, or consistent with national planning policy, which requires growth to be planned where infrastructure is available or can be secured.

7. Affordable Housing Allocation
I support the principle of providing affordable homes for local residents, especially young families, first-time buyers, and key workers who cannot afford market rates.
Well-planned affordable housing can help maintain a mixed and vibrant community and retain younger residents. Affordable homes in Dinas Powys could reduce commuting pressures by allowing residents to live and work locally. However, the RLDP does not provide clear evidence for how many affordable homes are needed in Dinas Powys or what types of homes are required for different groups (families, older residents, low-income households). There is insufficient information about how and when affordable homes will actually be delivered alongside market housing.
Without clear delivery plans or safeguards, affordable homes may not remain genuinely affordable in the long term. Concentrated or poorly planned affordable housing may put pressure on local schools, healthcare, transport, and green spaces, which are already constrained in Dinas Powys. The Plan does not explain how affordable housing will be integrated with market housing to create sustainable, mixed communities rather than segregation or social imbalance. Because of the lack of clear evidence, delivery mechanisms, and mitigation for potential negative impacts, I do not consider the Plan sound in terms of affordable housing in Dinas Powys.
 
8. Community Cohesion & Social Integration
I am concerned that the Plan, as currently drafted, does not ensure new growth will support strong, healthy, and inclusive communities. Until the Council provides clear evidence and enforceable measures addressing community cohesion, housing mix, and health impacts, I cannot have confidence that the Plan is sustainable or fair.
Impact on Community Cohesion and Social Integration
I am concerned that the Plan does not explain how new housing and growth will integrate with existing communities. There is a risk that rapid development could strain local services, schools, and community spaces, and make it harder for neighbours to get to know one another.
I would like to see evidence that social infrastructure will keep pace with population growth and that communities will remain inclusive and connected.
Risk of Over-Concentration of Affordable Housing
I am concerned that clusters of affordable housing in certain areas could lead to pockets of social exclusion or limit access to opportunities.
The Plan does not explain how it will ensure a good mix of housing types and tenures across the Vale. I ask that the Council provide evidence that housing allocations will support socially balanced, inclusive communities.
Impacts on Mental and Physical Wellbeing
I am concerned about increased traffic, air pollution, noise, and the loss of green spaces affecting health and wellbeing. The Plan does not provide clear commitments to protect or improve accessible green spaces or safe walking and cycling routes. I would like to see evidence that the Plan has assessed the health impacts of growth and will take steps to mitigate them.
 
9. Climate Change & Sustainability
I am concerned that, as drafted, the Plan does not provide enough evidence or practical measures to ensure new development is sustainable and climate resilient. The RLDP is not fully justified, effective, or consistent with national policy on climate change and sustainability.
Key gaps include alignment with carbon reduction targets, enforceable delivery of low-carbon travel, energy-efficient homes, sustainable drainage, and climate-resilient infrastructure. Without clear policies and enforceable commitments on low-carbon travel, energy-efficient homes, sustainable drainage, and climate-resilient infrastructure, the Plan risks harming both the environment and the wellbeing of communities.
Alignment with Welsh Government’s Carbon Reduction Targets
I am concerned that the Plan does not explain clearly how new homes, workplaces, and other development will help Wales meet its legally binding carbon reduction targets.
Without this, there is a risk that growth in the Vale could increase emissions rather than reduce them. I would like to see evidence showing how this (and each) new development contributes to lowering carbon emissions.
Promotion of Low-Carbon Travel, Energy-Efficient Homes, and Sustainable Drainage
I am worried that the Plan relies too much on people walking, cycling, or using public transport without clear plans to make this happen. There is also little information on whether new homes will be energy-efficient or if systems to manage rainfall and reduce flooding (like sustainable drainage) will be properly installed and maintained. I want to see clear, practical measures to make low-carbon travel, energy-efficient homes, and safe drainage a reality. Resilience of Infrastructure to Extreme Weather Events I am very concerned about the impacts of extreme weather, including flooding, heatwaves, and storms, on roads, utilities, and homes. The Plan does not clearly show how new developments or existing infrastructure will be designed to cope with these risks.
I would like to have assurance that any buildings, roads, drainage, and community facilities will be climate-resilient and protect people’s health and safety.
 
10. Plan-making Process & Evidence Base
In my view, the RLDP is not fully justified or effective in its current form with respect to plan-making and the evidence base. Key gaps include accessibility and transparency of evidence, consideration of resident and stakeholder feedback, and robust monitoring and review arrangements. Without clear and accessible evidence, demonstrated consideration of local feedback, and robust monitoring and review mechanisms, residents cannot be confident that the Plan will be fair, effective, or responsive to changing circumstances.
Clarity, Transparency, and Accessibility of Evidence
The RLDP is not always clear and is not easy to access.
Technical reports, data, and assumptions are often difficult to find or understand, making it hard for residents to see why particular sites or policies were chosen. The Council should provide accessible summaries and clear explanations so that everyone can understand and comment on the evidence.
Local Consultation and Consideration of Resident Feedback
I am concerned that residents’ views may not have been fully taken into account in shaping the Plan. It is unclear how consultation responses have influenced allocation decisions or policy wording. I seek assurance that feedback from local people and community groups has genuinely informed the Plan, and that future consultations will be inclusive and clearly reported.
Monitoring and Review Mechanisms
The Plan does not clearly explain how progress will be monitored or how changes will be made if things do not go as planned. For example, if housing delivery is slower than expected or infrastructure is delayed, there is little information on how allocations or policies would be adjusted.

HG1- KS2 - Eastbrook
Does not conform to Placemaking Principles in Policy SP4 Placemaking. As outlined by Rhys ap Owens, MP in his letter of objection.
Congestion - The Vale of Glamorgan are well aware that there is a huge congestion issue in Dinas Powys as huge amounts of traffic form with much of the western Vale using it as a route into Cardiff. The air quality on this road will significantly be effected by increased buildings at Eastbrook that will change the topography and movement of pollutants and also bring 500 extra cars a road your own studies show is over capcity. Barry to Cardiff traffic route has to come through Dinas Powys, you have already exploded development in Barry bringing so much more traffic. It will be gridlocked even more. Highways objections have not been met. Single access for over 100 homes is not acceptable.
Flooding - Ongoing issues with flooding from river Cadoxton. Flooding has become worse since more development has taken place in Dinas Powys. In 2020 a significant no. of homes were flooding. No measures have been taken to prevent this happening, despite the eastbrook site absorbing tonnes of water through absorption.
Active Travel - eastbrook station is inaccesible one side to those who are physically impaired. Dinas Powys has an ageing population and estimates over public transport are exagerated. The Route to Eastbrook station on pavements is not 1.5m wide as required. The walk around to the other side of the station is 1 mile for those who cannot use the stairs. . No one is going to take this route. Highways documents state that active travel must be provided, persimmon has not agreed to these. Persimmons assessments shows walking and cycling routes fail to meet required standards and alternative routes are unsuitable. Cardiff Road is too narrow for safe active travel. Unfeasible without property demolition.
Green Wedge - This land has historically been labelled as green wedge stopping the merge of llandough / dinas powys and penarth. Green wedge exists in policy designating open, undeveloped land between settlements to prevent urban sprawl and maintain distinct community identities.This wedge area acts as green corridor s of nature penetrating through or between developed urban areas. The site in its current form promotes wildlife, flora and fauna. It is also widely used by the community with its vast amount of public footpaths. No newt survey conducted.
Local Facilities - Dinas Powys Medical Centre is currently exponentially over subscribed and impossible to get an appointment there. This will only put further pressire on existing facilities.
Schools- The current two primary schools are at full capacity, so where will these new residents school their children? The current comprehensive has double the applicants for the spaces available so where will the proposed new residents attend comprehensive school.
This development would bring no benefit to Dinas Powys and only put further pressure on existing amenities and a road that cannot cope with more traffic. Why is it being considered when it has been refused before? How is it suddenly suitable?

I wish to formally object to the allocation of Site HG1 KS2 – Land North of Dinas Powys within the Replacement Local Development Plan. In my view, the site is unsuitable for development due to concerns relating to flood risk and drainage capacity, pressure on local infrastructure, constraints within the highway network, and the impact on the rural character and setting of the area.

FLOOD RISK AND DRAINAGE
The proposed development of approximately 250 dwellings would significantly increase the amount of impermeable surfaces within the area, including roofs, roads and driveways. While the proposal refers to the use of Sustainable Drainage Systems and water retention measures, there remains concern that such measures may not fully mitigate the additional surface water runoff created by development at this scale.

Existing drainage infrastructure within Dinas Powys already experiences pressure during periods of heavy rainfall. Any additional surface water discharge from the development will ultimately need to enter the wider drainage network before flowing toward the Cardiff Road corridor and downstream catchments.

Surface water within the village ultimately drains toward the Cadoxton River catchment, which has historically experienced flooding during periods of intense rainfall. Development of greenfield land inevitably alters natural drainage patterns and increases runoff volumes. Even where Sustainable Drainage Systems are installed, these systems generally release stored water gradually into the existing drainage network once capacity thresholds are reached.

Given increasing rainfall intensity associated with climate change, there is a risk that development of this site could place further pressure on the drainage network and potentially exacerbate downstream flood risk. Welsh planning policy, including Technical Advice Note 15 (TAN15), requires development to avoid increasing flood risk elsewhere and to demonstrate resilience to changing weather patterns.

PRESSURE ON LOCAL INFRASTRUCTURE AND SERVICES
Local infrastructure within Dinas Powys is already under considerable pressure. Local schools have widely reported capacity constraints within their catchment areas, and the local medical centre serves a growing population with limited expansion potential.

A development of approximately 250 homes would inevitably lead to a substantial increase in population and demand for education, healthcare and other public services. Without clear and deliverable infrastructure improvements alongside the development, the allocation risks placing unsustainable pressure on existing services.

Welsh national policy within Planning Policy Wales emphasises that development should only proceed where the necessary supporting infrastructure can be provided.

TRAFFIC AND HIGHWAY NETWORK CONSTRAINTS
Dinas Powys sits on a key commuter corridor between the Vale of Glamorgan and Cardiff, with a significant proportion of residents traveling toward the city for employment.

The road network through the village already functions as a constrained bottleneck, particularly along the Cardiff Road corridor where traffic regularly queues during peak commuting periods.

The Murch Road crossroads acts as a known constraint within the local highway network and frequently contributes to congestion during busy periods. Traffic already backs up along surrounding routes, and additional development traffic would inevitably worsen these conditions.

A development of approximately 250 dwellings would generate a substantial number of additional daily vehicle movements. Given the existing limitations of the local road network, it is unclear how this increase could be accommodated without further congestion and longer journey times.

While the site lies relatively close to Eastbrook Railway Station, proximity to a railway station alone does not ensure a meaningful reduction in car use. Many journeys undertaken by residents—including school transport, shopping and local travel—remain heavily dependent on private vehicles.

Without significant improvements to the surrounding highway network, allocating a development of this scale risks placing further strain on an already constrained commuter corridor.

IMPACT ON VILLAGE CHARACTER AND SETTLEMENT SETTING
The site lies on the northern edge of the village and currently forms part of the open countryside that contributes to its rural setting. Development at this scale risks eroding the existing settlement boundary and contributes to the gradually urbanising of the landscape between Dinas Powys and it’s neighbouring areas such as Cardiff, Llandough and Penarth.

Protecting the character and setting of existing settlements should remain an important consideration when allocating land for housing within the Local Development Plan.

CONCLUSION
I fully recognise the need to deliver new housing across the Vale of Glamorgan. However, housing growth must be directed toward locations where infrastructure, drainage capacity and the highway network are capable of accommodating additional demand without creating significant adverse impacts.

Given the combined constraints relating to transport infrastructure, drainage capacity and pressure on local services, allocating this site for a development of approximately 250 homes appears disproportionate to the capacity of the village.

For the reasons outlined above, I believe that Site HG1 KS2 – Land North of Dinas Powys represents an unsuitable location for development of this scale.

I respectfully request that Vale of Glamorgan Council reconsider the allocation of this site within the Replacement Local Development Plan.

This site is not suitable for allocation, and its inclusion would conflict with several key RLDP objectives, including sustainable transport, flood risk management, settlement hierarchy, landscape protection, and infrastructure capacity.
My objections are set out below.

1. The Eastbrook Site is not a sustainable or logical location for growth
The Dinas Powys Community Council’s planning consultant confirms that the Eastbrook site is not a logical extension of the settlement. It is separate from Dinas Powys, it is poorly connected, and would be served by only a single vehicular access from Cardiff Road at the northernmost limits of the village - asignificant distance form local services and amenities.
This means the allocation fails core LDP principles regarding:
 Compact, contiguous, sustainable settlement growth
 Accessibility to local services
 Minimising reliance on car travel

The RLDP proposes to allocate land that inherently cannot support sustainable transport patterns and would produce a heavily cardependent community.

2. Severe Traffic and Congestion Impacts
Traffic impacts are a major and wellevidenced concern. The RLDP objections note that increased traffic and congestion would result from the Eastbrook allocation, especially given poor access, poor transport options, and reliance on car commuting to Cardiff.
Bus services between Dinas Powys and Cardiff are not regular. The proposed settlement is some distance from Eastbrook and Cogan stations. Safe cycle routes do not extend beyond the junction for Llandough Hill. All of this makes it more likely that residents of any new development would rely on cars. Dinas Powys already suffers major congestion, with residents highlighting severe pinchpoints and inadequate road capacity. These concerns previously related predominantly to peak times, but increasingly delays and congestion on this section of Cardiff Road are the norm for large portions of the day. The single vehicular access would feed into a road at a congested junction for traffic to and from Penarth and Llandough. This area is already a bottleneck.
Allocating a site with only one access point onto an alreadyoverburdened Cardiff Road directly contradicts RLDP transport and climate objectives.

3. Significant Flood Risk Affecting the Eastbrook Area
Published evidence shows that parts of the Eastbrook/Dinas Powys area lie within floodrisk zones associated with the Cadoxton River, and that the community has experienced severe historic flooding, most recently in 2020 following the last significant housing developments, prompting governmentfunded flood defences.
The RLDP must comply with national planning policies requiring:
 Avoidance of floodrisk locations
 No increase in downstream flood impacts
 Protection of communities at existing risk

Allocating a large greenfield site that will replace permeable land with hard surfaces, increasing runoff and downstream flood risk, violates these principles.

4. Loss of Green Wedge, Landscape Integrity, and Ecological Value
The Eastbrook site forms part of a protected Green Wedge separating Dinas Powys, Penarth, and Llandough. Development here would cause significant loss of landscape and ecology value and would harm the Green Wedge’s function under the Vale of Glamorgan’s Policy MG18.
Green Wedges are intended to prevent settlement coalescence, protect landscape character, and maintain ecological continuity. Developing this area would directly conflict with those objectives.

5. Infrastructure Constraints: Schools, Medical Services, Transport, Drainage
Along with other residents, I have serious concerns about school capacity, medical provision, drainage, sewage infrastructure, and transport networks, all of which are already under strain.
The RLDP must ensure that allocated sites can be supported by existing or improved infrastructure. There is no evidence that the Eastbrook site meets this requirement, nor that mitigation is feasible or justified.

6. The RLDP Growth Strategy Does Not Justify an Unsuitable Site
While the Vale of Glamorgan must meet its housing targets, the RLDP is required to allocate appropriate and sustainable sites. Whilst this site could theoretically contribute to housing targets, the Council must still adhere to sustainability principles and avoid highrisk or disconnected areas. The Eastbrook site fails on sustainability, accessibility, flood risk and landscape protection grounds—and therefore cannot be justified as part of the RLDP’s housing supply.

Conclusion
For the reasons above, I request that the Vale of Glamorgan Council REMOVE the Eastbrook (North of Dinas Powys) site from the Replacement Local Development Plan (RLDP) because:
 It is a poorly connected, cardependent, unsustainable location.
 It would significantly increase traffic and congestion, with only one suitable access point.
 It presents high and unacceptable floodrisk impacts on existing communities.
 It would cause major loss of Green Wedge land, harming landscape and ecological value.
 It would place unmanageable pressure on local infrastructure.

These are all material and policyrelevant grounds fully supported by evidence submitted during the RLDP consultation

Planning reference: HG1 KS2
• No supporting infrastructure investment: There has been little to no investment in expanding local infrastructure to support further housing. Roads, drainage, utilities, and services are already stretched, yet development is being proposed without any clear plan to upgrade them.
• Existing gridlock on main routes: Traffic through Dinas Powys is already heavily congested during peak hours. Additional housing will inevitably introduce more vehicles onto roads that are already at capacity.
• Increased flood risk: The area already experiences regular flooding. Building over existing green land will reduce natural drainage and increase surface water runoff, making flooding more frequent and more severe.
• Pressure near a local hospital: Additional traffic generated by the development would pass close to a local hospital, risking delays for patients, staff, and emergency vehicles.
• Poor active travel connections: There are currently limited safe walking and cycling routes to the nearest train station. Without proper active travel infrastructure, new residents will be forced to rely primarily on cars.
• Loss of green space and wildlife habitat: The development would remove valuable green land that supports biodiversity and provides an important natural buffer for the community.
• Declining air quality: More housing and vehicle traffic combined with less open green space will inevitably increase pollution and reduce local air quality.
• Neglected road network: Many local roads are already in poor condition due to years of underinvestment. Increased traffic will only accelerate their deterioration.
• Schools and GP surgeries already full: Local education and healthcare services are already operating at capacity, and there is no clear provision to expand them alongside the proposed development.

I write to formally object to the allocation of Site HG1 KS2 – Land North of Dinas Powys within the Replacement Local Development Plan.
The objections I am about to highlight are not based in an emotional or a NIMBY response to the proposals, but based in genuine thought and scepticism, based on the information provided by VOG council. I would ask those considering these objections to take the same approach, and understand that, whilst I currently have no intention myself to do so, should these proposals for whatever reason by brought before the courts and tribunal service, through my own copy of this document which I will keep, I am willing to submit this as evidence. Therefore I would urge those reading, (who through this process should be relevant decision makers) to consider these objections and be sure of their answers should they dismiss them and later be called to testify as to those dismissals. It should also be considered that once this development has been built there will be no reversal and the consequences of the development will have to be met in perpetuity by all residence affected.

Transport impact:
based on an 5 day average of 8am-9am traffic, the traffic survey cannot be considered to give any accurate information of traffic flow and therefore any impact of this housing development cannot be assessed based on this. No consideration about the potential increase in pollution from more traffic has been made.
Eastbrook station is not accessible to all users, not having lifts or ramps. Given Eastbrook station being a key component on this development, this is a glaring issue with no current resolution.
There has been no input from Transport for Wales in this proposal, and supposition that the South Wales Metro scheme will alleviate the road networks from the additional stress of this development.
There is no evidence that residents in this new development will use public transport links just because they are there, and there has been no attempt to do so. As there are no amenities in the new development, whilst resident may or may not use public transport to commute to work, they are likely to travel via car for said amenities, increasing traffic that way and also ingraining habits that may affect their decision on commuting.

Flooding:
The maps in the literature suggest flooding risks in the brooks within the development area. To build on these seems unnecessary, and could cause flooding in other areas downstream of the development due to increased surface run off.

Green Wedge
The area appears to be being built on land designated as Green Wedge. This under Welsh Government policy PPW12 is land that ensures that there is a separation between individual settlements to preserve identity and character.

To summarise, I believe building a housing site that is on an area of flooding risk that will potential cause significant flooding to other local regions, with no amenities, with poor assessments on current transport services and mitigation to the transport infrastructure based on nothing more than a supposition of "if it is built they will come", whilst also impacting on green wedge land in an area with over subscribed schools, no impact assessment on leisure and hospitality footfall changes, as well as concerns on the limited scope of the proposal justification, lead me to believe that if I were in a position to either accept or decline this site within the development plan, I have not been given enough evidence to justify it against the potential negative impact, unlawful or otherwise, of the existing community.

Remove allocation.

I am writing to object to the prposed developement on Cardiff Road. 250 houses on what is left of the small amount of green space between Llandough and Dinas Powys is an absolutely ludicrous plan. The junction at the Merrie Harrier Inn is currently at a critical state with the excessive hospital traffic, to add another 250 homes which possibly means possibly 250 cars is going to create a very dangerous situation indeed. This is a dangerous plan which will cause immense congestion on what is already an excessively busy road and it should not go ahead.
