I am writing to formally object to the proposed development on Cardiff Road.

I have lived in Dinas Powys for over 15 years and am a married mother of two. We chose to raise our family here because of its strong sense of community, village character, and the balance it offers between accessibility and quality of life. I am deeply concerned that continued large-scale development is gradually changing that balance in a way that feels unsustainable.

Cardiff Road is already a heavily used main route between Barry and Cardiff, and congestion is a daily reality, particularly at peak times and during school hours. As a parent, I am particularly concerned about the impact of additional traffic on road safety, air quality, and noise levels. Increased vehicle movements would not only add to existing congestion but could also undermine efforts to promote safer and more sustainable travel within the village.

Local NHS services, including the GP surgery and pharmacies, are already operating under noticeable pressure. Appointments can be difficult to secure, and waiting times are increasing. Without clear and guaranteed improvements to infrastructure and healthcare provision, further housing growth risks placing additional strain on essential services that families rely upon.

The loss of green space is also deeply concerning. These areas are not simply undeveloped land, they contribute to biodiversity. Gradual erosion of spaces like these diminishes both environmental sustainability and the distinctive village atmosphere that makes Dinas Powys the place it is.
In its current form, the proposal does not appear to demonstrate that the necessary infrastructure, highway capacity, environmental mitigation, and community facilities are in place to support sustainable growth. For these reasons, I respectfully urge the Council to give significant weight to the impacts of development and to protect the long-term character and sustainability of Dinas Powys when determining this application.

There is only one Welsh medium primary school in the Penarth area. There is only one Welsh medium Comprehensive school in the whole of the Vale. Building a large unwanted

A development of this size would further dilute the Welsh language in a community where it is already a minority. With only one Welsh medium primary school in the area and one Welsh medium comprehensive school in the Vale, these schools are the places where many local children regularly hear and use Welsh. A large influx of new families would overwhelm this system, reducing opportunities for children to learn and use the language in both school and daily life. It also goes against the Welsh Government's ambition to reach one million Welsh speakers by 2050.

Roads and services are already at breaking point.

The allocation of a further 250 homes at the planned site is directly off Cardiff Road which brings increased congestion in an area which is regularly at gridlock status.
Our road infrastructure is at capacity it cannot cope now let alone with the increase in the volume of cars that extra housing will bring.
The increase in traffic is particularly concerning given the proximity to Dinas Powys infant school. There are two major areas of risk, pupil safety and exposure to vehicle emissions. It raises the likelihood of accidents during drop off and pick up times. Increasing congestion makes visibility poorer for drivers and pedestrians. It creates increased dangers for families crossing the road at crossing points. Schools should be a safe zone where children can travel independently and confidently. Increasing traffic undermines that principle. Car fumes contain nitrogen oxide and pollutants known to negatively affect health. Increasing traffic leads to higher concentrations of those pollutants. A clear risk to children and families, compromising future health to everyone. The infrastructure support is inadequate, the doctors surgery and local schools are already at capacity. My last concern and probably the most worrying is additional homes in a flood prone area. Dinas Powys has flooded many times, more in recent years as our environment changes.

Dinas Powys road and sewerage network insufficient capacity to support 250 new homes
Cardiff/Barry Road is gridlocked during peak times already
Frequent flooding during very heavy rain to low lying areas around Mill Brook and Cadoxton river. Strategic Flood Consequences Assessment misrepresented - the flooding assessment for the RLDP shows the Vale and their consultants JBA Consulting suppressing the December 2020 flooding in Penarth/Cosmeston and Sully and *lying* that the measures taken in Dinas Powys for *individual house protection* dealt with the Cadoxton flooding issue. It did not
Local Doctors already at capacity
Local schools already oversubscribed

I like many Dinas Powys residents have serious concerns with this application. We have concerns and issues with the following. Traffic flow on the Cardiff Road, not only at peak times but throughout the day, this includes traffic coming from Barry going into Cardiff. There are issues with the availability of doctors appointments currently, even without future increases in local population. Lack of dentistry. School availability and the severe congestion at school opening and closing times. There are also concerns regarding surface water flooding, which is likely to increase over time due to global warming and anticipated wetter winters. Traffic flow and traffic signal timing at the "Merry Harriers" junction and the Cardiff Road junction with Redlands Road, impacts the traffic flow through Dinas Powys. The signal sequencing and road condition at the "Barons Court" junction with Penarth is deteriorating. Any increase in housing in and around Dinas Powys will also increase the traffic flow "rat run" via Penyturnpike Road to Leckwith which is a narrow and poorly maintained highway. Dinas Powys is also subjected to power outages, has electrical capacity been factored into this project?

GP Surgery, schools and infrastucture needs to be looked at before planning is approved.
There has been a huge increase in traffic since more houses were buit in Barry with gridlock on Cardiff Road and Penyturnpike traffic increased with drivers having no care for any speed limits. This also needs to be addressed first.

I strongly object to the proposed housing development at Eastbrook in Dinas Powys, as it represents a harmful expansion that would fundamentally alter the character of this valued green area. Eastbrook serves as a natural buffer within the village setting. Dinas Powys already faces pressure on infrastructure, including traffic congestion, school capacity, and GP services, and further development risks exacerbating these existing strains without clear evidence of adequate mitigation. The loss of green space would undermine the rural identity that makes Dinas Powys such a desirable place to live, while setting a concerning precedent for future encroachment into surrounding countryside. For these reasons, the proposal should be reconsidered in favour of protecting the long-term environmental and community interests of local residents.

I am concerned about the plan to approve the building of a new housing estate in the area between Georges Row/ Highfield Close and Cardiff Road, Eastbrook, going towards Llandough Hospital,
My main concerns :-
1) Flooding : I am concerned this will increase the flood risk: repeated flooding in Dinas Powys, including Cardiff Road, and many houses a few years ago. Also historically in Eastbrook. This causes ongoing anxiety as well as the misery of the flooding itself.
2) Doctors-they are taking on more and more people, including after a closure in Penarth and I personally believe the service is deteriorating. Where will people register?
3) Schools: where will they go ? Also the infant department of the school is right by Cardiff Road and its pollution. Will that get worse?
4) I understand there is a thought, not in the plan, for an active route along the Lane running by and behind the newer block of houses on the north side of Georges Row. This is a private back alley held by the households, I am told, and there is no right of way for access to an estate. There is a public right of way at the top of Highfield Close. Also, surely pedestrians and cyclists could access Cardiff Road from the road/pavement entrance/exits for the estate. I express an interest as a relative lives there and says the householder are very concerned, including about security.
5) Cardiff Road 5 already a ''nightmare' at peak times.

How on earth is Dinas Powys and its infrastructure going to be able to support further development. The village is already oversubscribed in the schools and health centre. It is impossible to get a gp appointment now. Cardiff road, (where the development is proposed exit and entry) is already at over capacity. Travelling from Dinas Powys to Penarth and Cardiff is a nightmare journey with the road congested through most of the day. Cardiff Road was at capacity 5 years ago and there have been no upgrades since. Ten minute journeys take over half an hour. No new roads are promised, no new facilities are promised just more and more houses destroying our valuable countryside and environment eliminating wildlife on the way. More building will cause more flooding issues in an area which is already a high risk flood area. Does no one in the council have any sense at all. There are much better sites to consider than this one which will be ruining a valuable green belt area and will lead to the merging of Dinas Powys with Llandough. IT IS ABSOLUTELY RIDICULOUS.

My main objection to houses on Cardiff Road is the increased traffic. My day can be dictated by what is on the road. I often wait until the flow reduces. Then there's accessing Cardiff Road from Railway Terrace. We are at the mercy of other drivers, who slow down to let us out. With extra traffic lights on Cardiff Road, I very much doubt there'll be much consideration for people trying to success the flow.
Also the lack of any amenities in Eastbrook means always having to use a car. My nearest shop is at least half an hour walk for me as I am an OAP and Blue Badge Holder. The added car owners will all have to use cars for school pick ups, shopping, accessing work, hobbies, doctors, dentists. The list is endless and so will the car use also be, with the extra houses also proposed off Sully road, the area will be carnage. It's sad that there seems to be no consideration for anybody. Flooding is also a concern as there are existing problems which will be exacerbated by more demands.

We strongly oppose the proposed planning permission for 250 homes on Cardiff Road. Is this just the start for further planning in the same area. Reasons for oppositions at HG1 KS2. 1.Increase traffic affecting emergency services especially to hospitals. 2.Green belt impacted along with wildlife. 3.Over stretched doctors and schools. 4.Risk of flooding.

I wish to object to the plan to build 250 new homes on the site below Llandough Hospital towards Cardiff Road, Dinas Powys. This is a green belt boundary and will result in destroying habitats for wildlife and increase possibility of flooding in homes in Dinas Powys. Cardiff Road is already congested and buses are unable to keep to their timetables. With additional cars from these new houses it will be impossible for emergency services to reach people quickly. It is already very difficult to get an appointment at the doctors and schools are full and over subscribed. I therefore object very strongly to these 250 new houses being built.

My concerns about the new development in Dinas Powys are because of the increased traffic and congestion it will bring. I am also concerned that local public services are at capacity. There is also the impact the new development will have on wildlife including the reduction of the greenbelt.

250 new homes could bring 300-500 additional cars. Cardiff Road is already congested on a daily basis; causing pollution to residents. There would be an increase risk of flooding with water running off the Eastbrook site into the Cadoxton rives and flooding homes in the village.
There would be loss of wildlife; bats are seen nightly directly behind High field close. There are also buzzards and owls in the fields between Highfield close and Llandough Hospital. Local primary and secondary schools
are full and over subscribed. Local doctors are at capacity
Dinas Powys' population is continuously increasing and will lose its identity as a village. The green belt boundary will merge Dinas Powys with Llandough this space should be preserved.

This proposal would lead to the permanent destruction of a well established ancient green eco-system and the habitats of wildlife's including a variety of animals birds, bats, insects, trees, plants and invaluable flora etc.
Inadequate infrastructure-road are already over capacity and are constantly blocked leading to dangerous and life threatening situation for pedestrians, in particular school children. Buses and trains are currently full at capacity and currently can cope adequately for passengers. More traffic will lead to increased pollution for residents. Schools are currently full to capacity. The medical centre is oversubscribed.
The area proposed is prone to flooding and more rainwater washing into the Cadoxton River will invariably lead to further and more frequent flooding on Cardiff Road and the village. This will also increase the likelihood of water pollution. Over exploitation of the green wedge will change the nature of Dinas Powys from village to town.
The loss of the current eco-system will have a detrimental impact of many residents who ramble freely on this land at present.
The greywater sewage out fall from Llandough hospital seeps into this area which is neither safe or healthy for a new housing area.

I am writing to formally submit my objections regarding the proposed Local Development Plan (LDP) candidate sites in Llandough and Dinas Powys. Specifically, I am objecting to Site 444 (Eastbrook/Cardiff Road), Site 400 (Penlan Hill), and Site HG1 KS2.
My grounds for objection are outlined below:
1. Pressure on Local Infrastructure and Roads
The local road network, particularly the primary routes through Dinas Powys and Llandough, is already at absolute capacity. Increasing the volume of housing via sites such as 444 and HG1 KS2 will lead to further gridlock on the Cardiff Road. The existing infrastructure is insufficient to support the resulting increase in traffic, posing risks to both road safety and local air quality.
2. Lack of Sustainable Travel Options
Despite the proximity to existing settlements, these sites suffer from a lack of adequate travel infrastructure. Without significant improvements to public transport and safe pedestrian/cycle links, these developments will remain car-dependent, further exacerbating the congestion issues mentioned above.
3. Destruction of Green Belt and Woodland
The proposed development of Site 400 (Penlan Hill) and the sites in and around Llandough would result in the irreversible destruction of the local Green Belt. Furthermore, I am deeply concerned about the impact on local sites of woodland interest. These areas provide essential ecological buffers and are vital for local biodiversity; their removal for housing is environmentally unjustifiable.
4. Cumulative Impact
The inclusion of multiple sites, including the "small" section off Cardiff Road (Site 444) and the developments in Llandough, represents an over-development of the area. While I note that Site 429 (Pen-y-Turnpike Road) was not accepted, the remaining proposed sites still place an unsustainable burden on the community.
I trust that these points will be fully considered during the evaluation process.

I strongly object to this proposed new housing development as it will have a big impact on the village if the 250 homes are approved. It will bring further congestion to our roads and especially Cardiff rd as it is one of the main roads used as a thoroughfare. The road is always busy with traffic and slow moving and potentially further cars from the new houses will be a nightmare.
The local schools will not cope and they are over-subscribed already. Also doctors in Dinas Powys are at capacity as trying to get through to them at present times is very difficult and it will be worse with these further homes if built. There will be increased flooding to homes as it is at a high level now which has damaged homes due to the river cadaxton bursting and I as a resident was affected by this a few years ago. With all these things and issues in mind this new housing development simply cannot go ahead.

I object because-
1. Doctors and schools already at capacity
2. Increased congestion
3. Increased flooding
4. Limited access to Eastbrook Train station and parking at that train station
5. NHS services-Llandough hospital will be affected by the additional demand and congestion brough on by the development.
6. Reduced greenbelt
7. Cardiff Road, through Dinas Powys is the only through route for traffic from Barry, Rhoose and Llantwit Major other than Wenvoe Road which also suffers from congestion at Culverhouse Cross. The impact of such congestion will lead to air pollution which is already manifest at current levels-a real health hazard. And lastly if a by-pass is not forthcoming, problems will only further multiply.

I strongly object to the proposal for new housing (250) in Dinas Powys

I object on the following grounds
1) increase in flood risk to existing properties
2) Dinas Powys is at present classed as a village. This will increase size to a town, with none of the facilities needed by a town.
3) Loss of countryside
4) Considerable increase in traffic on already congested roads which are badly maintained.
5) Increase of patients at an already over-capacity health centre.

I am against this development for several reasons. 1] Flooding - I live in an area at risk of flooding from the River Cadoxton and regularly have flood alerts from the environment agency. Cardiff Road flooded a few weeks ago and I had water coming up my drive towards the house. Building all the houses on the proposed site will lead to more water entering the brook along Cardiff Road which cannot cope with severe rain as it is. This drains into the River Cadoxton which then floods houses within its path. 2] Traffic - Cardiff Road cannot cope with the traffic at present so more houses will equate to an average of 2 cars per property all entering Cardiff Road causing gridlock. 3] Lack of infrastructure - The doctors surgery is already over subscribed and causes great difficulty getting appointments. If all the new residents in the development register at the practice, getting an appointment will be impossible. The schools in the village are also full so where are all the children from the development going to go to school? 4] Active travel is not achievable - the station has limited access especially to the disabled and those with prams. The trains are unreliable and often get cancelled There are not enough parking spaces at the station to facilitate a park and ride service Walking routes are not suitable along Cardiff Road due to the narrow pavement on the brook side of the road and also the pollution used by the heavy traffic. 5] Congestion on Cardiff Road already makes it very hard for emergency vehicles to get through. All the extra vehicles will make this even harder. 6] Loss of green space. The village will become one with Llandough losing its village status. The land used for the houses means less green space for walking and will also have a huge impact on the wildlife.

I think this development is ill thought out and the council should consider more suitable sites. The Vale is a large area so why do all these houses have to be crammed into a village which is already too large for its infrastructure.

We strongly object to 250 more houses being built on Seel park area in Dinas Powis. We have lived in this area for 20 years, And travelling back an fore work has been a nightmare since the St Cyres, Behind Eastbrook train station and cross common road sites were all built. Total disrespect to the people who live in this area so far. We do not have enough facilities in the area as it is. Hence why we are waiting 2 weeks just for a phone call from the doctor!

Formal Objection to Planning Ref: HG1 KS2 – Proposed Development of 250 Dwellings off Cardiff Road, Dinas Powys

I am writing to submit a formal objection to planning application HG1 KS2, concerning the proposed construction of 250 dwellings on greenfield land between Eastbrook and Llandough, on the fringes of Dinas Powys. This site encompasses the river corridor and agricultural fields of Eastbrook, an area of significant environmental, landscape, and community value.

While the site is allocated within the Local Development Plan (LDP), allocation does not guarantee approval. Planning Policy Wales (PPW) makes clear that each application must still demonstrate compliance with national policy, local policy, and the Well being of Future Generations Act, and must not cause unacceptable harm. This proposal fails those tests. Furthermore, several of the assumptions made during the LDP allocation process are now outdated, and new evidence demonstrates that the development would have severe and irreversible impacts.

A summary of my objectionas are as follows:
1. Traffic and Congestion – Mitigation Claims Are Not Credible
2. Flood Risk – SuDS Cannot Replace Natural Floodplains
3. Schools, GP Surgeries, and NHS Services – Section 106 Cannot Fix Structural Capacity Issues
4. Biodiversity and Wildlife – “Net Gain” Claims Are Misleading
5. Loss of Greenfield Land and Landscape Character – Allocation Does Not Override Harm
6. Public Transport – Proximity Does Not Equal Capacity
7. Village Identity and Community Cohesion – Design Codes Cannot Prevent Overdevelopment
8. Policy Compliance – The Proposal Fails Multiple National and Local Tests

My objections, including rebuttals to anticipated counter arguments, are set out below.

1. Traffic and Congestion – Mitigation Claims Are Not Credible

Cardiff Road, Dinas Powys Hill, and the approaches to Llandough are already heavily congested at peak times. The Dinas Powys Transport Network has long been recognised as operating beyond capacity, with no major upgrades delivered.

The developer may argue that a Transport Assessment (TA) and minor junction improvements will mitigate impacts. However:
• TAs routinely underestimate trip generation, relying on outdated modelling and optimistic modal shift assumptions.
• Eastbrook Station is already at peak time capacity, and rail services cannot absorb hundreds of additional commuters.
• Bus services are infrequent and unreliable, and no enforceable commitment exists to improve them.
• The road network is physically constrained by existing development, meaning no meaningful widening or reconfiguration is possible.

PPW requires development to avoid “unacceptable harm” to highway capacity. This proposal would significantly worsen congestion, air quality, and journey times, with no realistic mitigation available.

2. Flood Risk – SuDS Cannot Replace Natural Floodplains

The proposed site includes low lying fields adjacent to the Eastbrook river, which already experience surface water accumulation. Under TAN 15, highly vulnerable development such as housing should not be located in areas at risk of flooding unless stringent tests are met.

The developer may claim that Sustainable Drainage Systems (SuDS) will control runoff. However:
• SuDS cannot replicate the absorption capacity of natural floodplains.
• The site’s topography funnels water toward existing homes in Eastbrook, meaning any increase in runoff, even if “controlled,” raises downstream risk. In recent years Dinas Powys has seen increased Flooding Incidents.
• Climate change projections used during the LDP process are now outdated; rainfall intensity has increased significantly.

PPW and TAN 15 emphasise a precautionary approach. Building on a functional floodplain contradicts both the letter and spirit of national policy.

3. Schools, GP Surgeries, and NHS Services – Section 106 Cannot Fix Structural Capacity Issues

Local schools, GP practices, and Llandough Hospital are already operating at or near capacity. The developer may argue that Section 106 contributions can fund expansions. However:
• There is no physical space to expand several existing local schools, and staffing shortages cannot be solved with financial contributions.
• GP practices in Dinas Powys, Penarth and Llandough already have long waiting times; the Cardiff & Vale Health Board has repeatedly acknowledged workforce pressures.
• Llandough Hospital is a regional facility already under strain; additional population growth will worsen waiting times.

PPW requires developments to demonstrate that essential services can accommodate growth. This proposal fails that test.

4. Biodiversity and Wildlife – “Net Gain” Claims Are Misleading

The Eastbrook fields and river corridor form an important wildlife habitat supporting birds, bats, amphibians, and small mammals. The developer may claim that ecological mitigation, such as bat boxes or landscaping, will deliver biodiversity net gain.

However:
• Net gain cannot replace the loss of mature, interconnected habitats.
• Artificial features do not replicate the ecological function of natural riverbanks and fields.
• The site forms part of a wider ecological network linking Cosmeston, Cogan Wood, and the Dinas Powys countryside; fragmentation would be permanent.

The Environment (Wales) Act 2016 requires public bodies to maintain and enhance biodiversity. This development would do the opposite.

5. Loss of Greenfield Land and Landscape Character – Allocation Does Not Override Harm

The Council may argue that the principle of development was established through the LDP. However:
• PPW states that allocated sites must still be assessed against current evidence and policy at application stage.
• The LDP was adopted in 2017; since then, climate, transport, and infrastructure pressures have intensified, making previous assumptions outdated.
• The site forms one of the last remaining green buffers between Dinas Powys and Llandough; its loss would fundamentally alter the settlement pattern.

The proposal conflicts with LDP Policy MG17 (Special Landscape Areas) and PPW’s placemaking principles.

6. Public Transport – Proximity Does Not Equal Capacity

The developer may argue that the site is “sustainably located” due to Eastbrook Station. However:
• Peak time trains are already full.
• The station has limited parking and no capacity for expansion.
• Bus services are infrequent, with no guaranteed improvements.

PPW requires realistic, not theoretical, sustainable transport options. This development would remain car dependent.

7. Village Identity and Community Cohesion – Design Codes Cannot Prevent Overdevelopment

Dinas Powys and Llandough are distinct village communities. A development of 250 homes—effectively a new estate larger than many existing neighbourhoods, would overwhelm the existing settlement pattern.

The developer may argue that design codes will ensure integration. However:
• Scale, not design, is the primary issue.
• The development would merge communities, erode village identity, and contribute to suburban sprawl.
• PPW requires developments to respect local character and sense of place; this proposal does neither.

8. Policy Compliance – The Proposal Fails Multiple National and Local Tests

The developer may claim alignment with PPW, the Well being of Future Generations Act, and the LDP. However, the proposal conflicts with:
• PPW (Edition 11) – placemaking, climate resilience, sustainable transport
• TAN 15 – flood risk
• Environment (Wales) Act 2016 – biodiversity duty
• LDP Policy MD2 – infrastructure capacity
• LDP Policy MG17 – landscape protection
• Well being of Future Generations Act – long term environmental and community wellbeing

Allocation alone does not override these conflicts.

Conclusion

For the reasons outlined above, I strongly object to planning application HG1 KS2. The proposal would cause significant and irreversible harm to the environment, local infrastructure, community identity, and the wellbeing of current and future residents. The mitigation measures proposed are insufficient, unrealistic, or based on outdated assumptions. The development fails to meet the requirements of national and local planning policy and should therefore be refused.

I object to this housing on cardiff road dinas powys.
We are at gridlock already

Strongly object! How can this be approved? Where is the common sense? Dinas Powys is a village and it is already being destroyed by it being used as a thoroughfare. Traffic is already building up daily with cars at a standstill or moving. These extra proposed houses will undoubtably cause havoc with approx. 300-500 cars on roads that are already overused and unfit for cars to drive safely (the pot holes are ridiculous and dangerous. One just filled in our street was already failing the same day. Schools are at capacity already, not to mention underfunded and unable to provide for local children who are struggling with/ND/trauma background. I digress. Not to mention the doctors surgery not coping, unable to get through to make appointment. The risk to flooding is high to a village already hit hard from previous flooding. This proposed 250 houses cannot go ahead. There is no reasonable argument to be made for this to go ahead. There are other reasons to which I haven't mentioned yet. NHS emergency vehicle access will only be greatly affected. Only today I witnessed the heavy traffic on Cardiff Road, and two emergency vehicles struggling to get past traffic at a standstill. Lives are already at risk due to volume of traffic, this will only put greater pressure on the amazing NHS staff who already operate under crazy conditions.

1. Introduction
I submit this statement as an individual directly affected by the implications of the RLDP proposals for Dinas Powys. My concerns relate to transport capacity, mitigation, air quality, sustainable transport, and the adequacy of the flood risk evidence. Across all these areas, the Plan relies on incomplete, outdated or generic material which does not reflect known local conditions.

2. Traffic Capacity
The RLDP does not demonstrate that the Dinas Powys highway network can support the proposed development levels. Congestion on Cardiff Road, St Andrew’s Road, the A4055 and associated junctions is already severe during peak hours.
No settlement specific junction modelling, peak hour assessments or baseline congestion data are published. Without these core datasets, it is impossible to verify the assumption that growth can be accommodated without significant capacity impacts. The cumulative effect of allocations therefore remains untested.

3. Mitigation Measures
The Plan fails to identify clear mitigation for the traffic impacts expected in Dinas Powys. Proposed measures are broad and lack certainty regarding:
• the specific interventions proposed,
• their phasing,
• whether funding is confirmed, and
• how delivery and enforcement would be secured.
There is no guarantee that necessary mitigation will be delivered in advance of development, undermining the Plan’s effectiveness.

4. Air Quality Impacts
The RLDP does not provide a sufficiently detailed assessment of air quality impacts arising from increased traffic in Dinas Powys. No location specific modelling or clear cumulative scenario testing is published.
There is no evidence that worst case conditions have been evaluated or that the Plan can ensure continued compliance with statutory air quality thresholds. The lack of robust analysis means potential impacts on public health and sensitive locations remain uncertain.

5. Sustainable Transport Delivery
While sustainable travel is promoted in principle, the RLDP provides no firm commitments for Dinas Powys. The Plan does not identify the specific schemes to be delivered, the level of funding secured, or when improvements will be implemented.
Given the absence of detailed and deliverable measures, the modal shift assumptions underpinning the Plan are not justified. Without realistic alternatives to car use, traffic and air quality impacts are likely to be greater than the Plan assumes.

6. Flood Risk and Outdated NRW Evidence
A further and significant concern is the absence of up to date flood mitigation evidence for Dinas Powys. The RLDP relies on information that predates the major flood event of 23 December 2020 and does not incorporate any post event modelling or revised strategy by Natural Resources Wales (NRW). This represents a critical soundness failure.
6.1 Reliance on Outdated Strategic Material
The Vale of Glamorgan’s Local Flood Risk Management Strategy (LFRMS) is dated December 2013 and identified Dinas Powys as an area of “significant future risk.”
However, this strategy is now over a decade old and predates both the 2020 flood and the updated climate change projections that followed.
6.2 Pre Flood Rejection of a Strategic Scheme
In September 2020, NRW completed an Environmental Constraints and Opportunities Record (ECOR). This assessment concluded that NRW was “unable to justify a capital flood scheme” for Dinas Powys, deeming it only “marginally cost beneficial.” NRW stated it would continue with “business as usual”, limited to manual channel clearing.
This decision was made three months before the December 2020 event which flooded 98 properties internally, clearly invalidating the assumptions underpinning the ECOR conclusions.
6.3 No Post Flood Mitigation Review
Although NRW carried out flood reconnaissance in January 2021 and contributed to the Section 19 Flood Investigation Report (published November 2021), these documents are investigative rather than strategic.
Critically:
• The Section 19 report explicitly states that no catchment wide hydraulic modelling has been undertaken using the actual data from the 2020 flood.
• The report’s recommendations include asking NRW to “consider the viability of options to reduce flood risk,” confirming that no updated mitigation strategy had been developed as of late 2021.
As of now, NRW has not produced any new catchment model or revised mitigation plan for Dinas Powys that incorporates the 2020 event.
6.4 Implications for RLDP Soundness
The RLDP does not include any analysis of the 2020 flood event and does not require developers to address its implications. Without an updated NRW approved model that incorporates the most significant flood event in local memory, the Council cannot demonstrate that additional development—particularly the proposed 250 dwellings—will not increase flood risk within the catchment or elsewhere.
The flood evidence base supporting the RLDP is therefore functionally obsolete and cannot form the basis of a sound spatial plan.

7. Evidence Gaps and Overall Soundness
Across transport, air quality, sustainable travel and flood risk, there are major evidence gaps which undermine the RLDP’s justification and effectiveness. The absence of robust, transparent, and up to date assessments means the Plan does not meet national policy requirements.
In particular:
• No junction capacity modelling or peak hour traffic assessments,
• No cumulative air quality modelling,
• No defined or enforceable mitigation strategy,
• No committed sustainable transport delivery plan, and
• Flood evidence based on material rendered invalid by the December 2020 event.
Given these shortcomings, the RLDP cannot be considered sound as applied to Dinas Powys.
________________________________________
8. Conclusion
The RLDP does not demonstrate that proposed growth in Dinas Powys can be accommodated safely or sustainably. Significant gaps remain in the evidence relating to traffic capacity, mitigation delivery, air quality, sustainable transport, and flood risk.
Until these deficiencies are addressed—particularly the lack of updated NRW flood modelling and the absence of settlement specific transport evidence—the Plan should not be found sound.

I object to HG1 KS2

Reject plans for HG1 KS2.

Dear sir,

I strongly oppose the proposed plan. I live in Georges Row adjacent to the proposed site. I travel this road every day as I am primary carer for my Father who also lives in dinas. It takes forever to get out of George's row and then often I'm joining a queue. This is not even on rush hour, but by the time I travel home late afternoon it's often gridlock.

I was born in dinas Powys and the flooding risk is real. After days of heavy rain the man hole covers start bubbling up on the Cardiff road and the water gathers across. The culvert along Cardiff road burst over recently and it was closed. The cadoxton river has also burst flooding houses. If you take away the fields, trees and natural ditches that hold water that flooding risk will be higher. When it's been torrential I have to keep an eye on any alerts to make sure I can get home. There is a lane on the planning into Georges row, this does not belong to the council it's a private lane and narrow.

This is a beautifully diverse area for nature. If the councillors walked it they would see the wild life. Foxes, badgers, hedgehogs, birds, bats swooping, so much in the ditches and beautiful flowers and established trees. We are told to go green recycle etc., but this will mean distruction of those things and added car pollution. As well as the pollution due to lorries and building.

The destruction of greenbelt land will then effect the identity of Dinas Powys. It divides Dinas and llandough it's not to be used because it suits a building plan.

There is only limited parking at Eastbrook station. Schools are full and oversubscribed, and the doctors surgery is hard enough to get an appointment now without further development.

Please don't ignore these comments, say no to the plans.

Yours faithfully

Mrs Linda wilcock

I object to the development on the following grounds:
1. It will lead to even more congestion on Cardiff Road, which is constantly busy. It will also lead to increased pollution.
2. The local health centre and schools are already at capacity.
3. Increase the risk of flooding as the water run off from the site will impact on the Cadoxton river.
4. Loss of village identity
5. Reduction of greenbelt land
6. Loss of wildlife in the area
7. Emergency services will be adversely affected by the additional congestion brought on y the development.

Increased congestion + pollution of air. Increased flooding which you have lied about. Doctors and schools already at capacity. Loss of wildlife. Breaking law too near to Llandough. I have already sent a detailed letter from a very reliable source check your legality of this.

To the Clerk of the Council
Dear Sir or Madam
I would like to Protest about the Proposed Plan to Build 250 Houses on land at Eastbrook.
I am writing to you as i was unable to attend the Meetings that were held about this problem
As the Brook runs right in front of the property and we were Flooded a few Years ago on Christmas Eve
when one of the Sluice gates was being repaired it is so worrying to hear the they want to build Houses on One of the Contributories of the Brook we know when the tide is in as the Brook backs up then when the tide goes out so does the Water in the Brook
As i understand it most of the surface Water in Dinas Powys goes into the Brook and not down the Sewers
by Building more houses Side of the Brooke that runs through the Fields were they want to build those Houses
I would imagine that would put the risk of our Houses being flooded Quite Often has nobody thought about this
problem the Main road would be Flooded as well and the houses down in the Corner of our Estate that have been
Flooded quite often would be Flooded even More so please consider us People living in this Village and do some thing about the Planning Please
I when to a Meeting some time ago and Mentioned about the tide but nobody seamed to know about it then but we People living here see it every Day Especially when it Rains.
I wonder could you please give me your thoughts on this.
Looking forward to hearing from you.
