No more houses in lesser green area. Local wild life needs to be protected.

Congestion
Pollution
Destroys wild life
Loss of habitat
No additional infrastructure
Traffic delays

Do not build any extra houses in Dinas Powys, they are not needed.

Dinas doesn’t need any more housing. Traffic throughout the day is already at capacity, and adding approx 500 cars extra cars is madness. The roads are in a shocking state. I live in Dinas and work in Penarth and my daily commute is getting longer and longer. The site is already prone to flooding, so those homeowners will not be able to obtain house insurance.

The KS2 requirements say: a secondary access closer for emergencies as well as pedestrians and cycling. Highways asked the applicant to respond but they were unsuccessful
# no drawings of the sole suggested access onto Cardiff Rd using the farm gateway by Wayside cottages
# blockage of access to carparking at one side, removal of parking space at the other
# limited visibility with roadside cottages and narrow pavement, roadway too narrow for a turning lane
# reported impossible to insert cycling and pedestrian lanes on CardiffRd to meet Active travel minimum standards so gave up.
The development is unviable.

Increased flooding risk
Increased traffic with no new infrastructure
Not enough space at gp surgery
Schools already over subscribed

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 are set out below and relate to 10 key areas of concern.
• 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
NB Topics are not listed in priority order, they are all important, and I expect each to be given full consideration to be given to each
 
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.

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.

1. Introduction
I submit this objection statement as an individual directly affected by the implications of the RLDP proposals HG1 KS2 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.

This is a v-poor development site - Flooding is a major issue around these fields. Traffic - Already serious tailbacks, and ensuring pollution as a result. Infrastructure - Roads, Schools, Doctors etc not already subscribed. Nature - This green corridor between urbanisation is of great importance not just for diversity of wildlife, but also human health including mental wellbeing. Village life- The old village has already had it's character impacted by developments further development erodes the essence of this great community. Past Developments - shoddily put up on flood plain and regular people experience flooding in their homes. Final words - we can do better than this incongruous proposal - thank you.

I wish to object to your proposal to build another 250 houses in Dinas Powys. My daughter bought a house at scholars park in Dinas through your Aspire to own scheme. She was very happy there until you housed two drug addicts 3 doors up from her. She has spent the last 4 years writing compliant letters to United Welsh and having to phone the police constantly to no avail. All of the neighbours have also done the same. When you offered this affordable homes scheme at no stage was she told she would be living in close proximity to drug addicts. How many more druggies will be houses in this development? I have lived in Dinas Powys for 50 years and it is not the safe village it used to be. You have brought crime to our village and my daughter and my mental health has suffered as a result. It's not just the addicts its all their friends, people delivering drugs and affecting nightly, and you are well aware of this because residents have complained via Chris Franks and Malcolm Phillips.

I am concerned about the increased traffic on Cardiff Road which is already congested. Also the reduced greenbelt, increased risk of flooding and the pressure on local services.

I wish to object to the proposed construction of a further 250 house in Dinas Powys for the following reasons:
a) From personal experience it seems that in Dinas Powys, notably the "scholars park" development, a number of "affordable" homes, have been used to house drug addicts, which has caused years of distress despite repeated complaints to the police and the VOG council's partners "United Welsh". It would appear that "new build", affordable housing is being used to house "drug addicts" in the local community, without informing them. This has lead to years of distress, frustration and despair for local residents.
b) Building large scale housing, without improving infrastructure, will lead to traffic chaos, drainage problems and mean gridlock in Dinas Powys, the main route from Barry into Cardiff and possible increased flood risk to an already worried local population, many of whom have been flooded in recent times
c) Adding a large number of families to the local population will put an increased strain on local services with oversubscribed schools and put pressure on an already stressed and straining health practice.

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 to be given to each. 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

The road is over congested as it is adding another 250 homes with approximately 1000 cars (as homes seem to have 3-4 cars) is ludicrous and needs urgently to be reviewed. Llandough and Dinas Powys have become the main route from Cardiff to the Vale of Glamorgan but they do not have the infrastructure or the public transport to support this, therefore residents heavily rely on cars. These areas are not supported in building roads to alleviate some of this congestion, reports mention Cardiff Road was at capacity 5 years ago, yet more traffic has been added to it, there have not been any improvements to this area, the extra traffic from this site will add to existing queues and be even more detrimental to air quality!
The traffic congestion is a real concern for residents requiring emergency services, the roads are clogged for more than half of the day, emergency services cannot get through the traffic congestion currently, adding more traffic will make this worse. Any increase in side roads will make this worse, how will these residents access Cardiff Road?
We are unable to currently get a doctors appointment, adding at least another 250 to 1000 people will again exacerbate this situation.
This is also a huge loss to local wildlife, and will destroy vast habitats for all wildlife.
Dinas Powys already suffers with flooding, removing green fields and adding more concrete the water will have no where else to go and will exacerbate the flooding that frequently occurs.
This area also marked a distinction between Llandough and Dinas Powys, both villages very proud of their village structure and distinctive identities, this shows as residents are passionate to keep their villages and not be merged into a single area, residents views and concerns should be taken into account in these decisions.
Green spaces should be kept for wellbeing and the benefits that they provide in absorbing pollutants and providing a positive contribution to our mental health, along with the benefits that they bring to climate change.

PLANNING REFERENCE HG1 KS2
I strongly object to the proposal to build 250 houses on Cardiff Road, Dinas Powys.
As a local resident, there are a number of factors that make this proposal completely untenable and
disastrous for the local area both in the short and long term.
Traffic: Congestion along Cardiff Road is already a huge issue and has been for many years. Increased
housing in Barry has exacerbated this problem, with Cardiff Road the main access route to Cardiff and
beyond. Adding 250 houses next to a main road with daily traffic jams, especially at peak times, will
further add to the congestion, having a detrimental effect on the environment and causing further
disruption to already frustrated local residents.
Flooding: Dinas Powys has suffered from an increased flood risk over recent years - both from local
rivers and insufficient residential drainage - both clearly visible on flood risk maps. The installation of
flood barriers and flood prevention measures for numerous homes merely aims to reduce the impact of
damage in the inevitable event of flooding - likely to further increase with the impact of climate change.
Building a significant number of houses with associated infastructure on green fields adjacent to Cardiff
Road will inevitably contribute to raisedwater levels in both the Eastbrook River and the River Cadoxton,
causing increased floodrisk to current homes. This is unacceptable.

Dinas Powys has developed 3 large housing developments over recent years, most recently a huge estate
at Scholar's Park, formerly a large green space area. Building on green field land separating Dinas Powys
from Llandough will destroy a vast wildlife area and will remove one of the last significant green spaces in
the village, decreasing biodiversity and eco-system resilience. This will also adversely affect the health
and wellbeing of local people, replacing nature with another congested housing development.
Active Travel: This is currently an issue for local residents. Eastbrook Station is inaccessible for many
people due to the steps/bridge to access both sides of the platform. The proposed site has poor access to
the station due to the narrow pavements and proximity to the Cardiff Road. This is not a successful
example of 'active travel' and will more likely result in more car journeys for potentially 500 additional
cars.
Local Services - Medical/Education: These are at capacity. Adding significant additional housing without
considering the impact on education and GP accessibility is irresponsible

The road is over congested as it is adding another 250 homes with approximately 1000 cars (as homes seem to have 3-4 cars) is ludicrous and needs urgently to be reviewed. Llandough and Dinas Powys have become the main route from Cardiff to the Vale of Glamorgan but they do not have the infrastructure or the public transport to support this, therefore residents heavily rely on cars. These areas are not supported in building roads to alleviate some of this congestion, reports mention Cardiff Road was at capacity 5 years ago, yet more traffic has been added to it, there have not been any improvements to this area, the extra traffic from this site will add to existing queues and be even more detrimental to air quality!
The traffic congestion is a real concern for residents requiring emergency services, the roads are clogged for more than half of the day, emergency services cannot get through the traffic congestion currently, adding more traffic will make this worse. Any increase in side roads will make this worse, how will these residents access Cardiff Road?
We are unable to currently get a doctors appointment, adding at least another 250 to 1000 people will again exacerbate this situation.
This is also a huge loss to local wildlife, and will destroy vast habitats for all wildlife.
Dinas Powys already suffers with flooding, removing green fields and adding more concrete the water will have no where else to go and will exacerbate the flooding that frequently occurs.
This area also marked a distinction between Llandough and Dinas Powys, both villages very proud of their village structure and distinctive identities, this shows as residents are passionate to keep their villages and not be merged into a single area, residents views and concerns should be taken into account in these decisions.
Green spaces should be kept for wellbeing and the benefits that they provide in absorbing pollutants and providing a positive contribution to our mental health, along with the benefits that they bring to climate change.

I am writing to formally lodge my objection to the proposed allocation of site HG1 KS2 (250 dwellings at Cardiff Road/Eastbrook) within the Deposit Plan. I contend that this allocation is unsound and fails to meet the required Tests of Soundness (specifically Test 2: Appropriateness) as set out in the Development Planning Manual.
My objection is based on the following material and statutory considerations:
1. Severe Cumulative Impact on the Highway Network
Planning Policy Wales (PPW) Edition 12 is clear that development should be prevented where the residual cumulative impacts on the road network are severe.
As a local resident, I experience this "severity" on a daily basis. My son attends a local primary school and participates in various after-school activities. As these activities are frequently in locations not served by viable or frequent public transport, I am reliant on the car to transport him. Currently, the congestion on Cardiff Road is so chronic that he is regularly late for his commitments. Adding a further 250 dwellings and an estimated 400+ additional vehicles to this specific corridor will lead to a total failure of the local transport network. This proposal will move the situation from "congested" to "non-functional," directly harming the quality of life and social development of local children.
2. Breach of the Well-being of Future Generations (Wales) Act 2015
The Council has a statutory duty to act in accordance with this Act. By proposing a development that further gridlocks the village and effectively prevents children from accessing extracurricular activities in a timely manner, the Council is failing the "Social" and "Cultural" well being goals. This plan fails to prioritise "Prevention" (preventing the total collapse of local infrastructure) and "Integration."
3. Unacceptable Settlement Coalescence & Loss of Village Identity
Dinas Powys is a historic village, not an urban extension of Cardiff or Llandough. Site HG1 KS2 represents an unacceptable coalescence of settlements. It fails to provide a "defensible boundary" and destroys the "Green Wedge"which is vital to maintaining the village’s distinct identity. This violates PPW 12 guidelines regarding the protection of the character and setting of distinct communities.
4. Infrastructure Capacity and Environmental Risk
• Education & Health: The plan is unsound as it lacks a deliverable strategy to mitigate the massive oversubscription at local primary and secondary schools and GP surgeries.
• Flood Risk: The Eastbrook site is a known run-off area. Increasing impermeable surfaces with 250 homes will inevitably increase the downstream flood risk for the wider village, contravening TAN 15.
• Sewerage: I am deeply concerned regarding the capacity of the existing Victorian sewerage network to handle increased loads without leading to further untreated discharges into the local environment.
Conclusion
The allocation of HG1 KS2 is not the most appropriate strategy when compared to reasonable alternatives. It places an unsustainable burden on an already failing infrastructure. I urge the Council to remove this site from the RLDP to ensure the plan remains sound and legally compliant.

I disagree and object strongly!!!! There is no place for more housing in Dinas Powys (HG1KS2 - Ref No for complaint). There is insufficient doctors, the roads are already overloaded. There is not sufficient disabled access to train services plus insufficient parking!! The risk of FURTHER FLOODING is a BIG concern, having been hugely impacted by this at Xmas time a few years ago! Dinas Powys should be allowed to remain a village not become a town!!! NO NO NO to more housing!!!! Floods a huge concern!!!!!

The Eastbrook site fails tests of soundness and should be removed from the plan.

I strongly object to the allocation of development in HG1 KS2 Eastbrook in the RLDP because it is environmentally unsafe, increases risks of flooding in the Dinas Powys area and would overwhelm local infrastructure. Local roads are already unable to cope with traffic volumes, air quality diminishes with growing traffic and more housing would only aggravate this. The plan offers no proven flood mitigation and residents already live with the threat of increasing flooding. It also erases one of the last local green spaces that our community depends on. Local schools and health centres are already at capacity and would struggle with demands posed by the proposed 250 dwellings. The Eastbrook site fails tests of soundness and should be removed from the plan.

HG1 KS2
We strongly object to this proposal. Our main objections are:
1) Increased traffic
2) Increased pressure on local services
3) Increased pollution
4) Risk of flooding

It has recently come to my attention that there is a proposal to build approximately 250 houses on the outskirts of Dinas Powys and I am writing to express my objections to this proposal.

I currently live (and have for 15 years) on Cardiff Road and have seen a huge increase in traffic along the road over the years. I do not believe that the current layout of the road can accommodate the additional traffic that these houses will bring with them, let alone the impact it will have on commuting times and more importantly the emissions from cars being expelled to the local area / residents, especially noting an Infant School on the main road where very young children are playing outside breathing in these chemicals. Whilst I appreciate the desire to increase the number of residents using public transport to alleviate some of this impact, that too has its own issues such as number of train carraiges, infrequency of buses etc. It also creates an issue of safety for pedestrians and cyclist along this route as the more cars - and no doubt frustrated drivers who are unable to avoid the constant gridlock of traffic - the more chance of someone being seriously hurt.

I also believe that the current amenities in the village - schools, doctors etc are unable to accommodate any further residents as the schools are all over subscribed as are all the other local schools within a reasonable distance, and the GP Surgery is already acting at max capacity with regards to appointment availability.

Furthermore, the loss of additional green space is further endangering the local wildlife which has already been affected by the 3 latest developments in Dinas Powys in the last few years.

Finally, I believe that if this development goes ahead it will have a huge effect on residents' mental health in general, as for the most part people have chosen to live in Dinas Powys as it is a small village with a very active community and this is slowly but consistently being erradicated by the continued building of houses which is changing the area from a village to a town like feel.

I have lived in Dinas Powys for over 70 years. I grew up living first on Penyturnpike and then, when I got married over 45 years ago, moved to Highfield Close. I have noticed how much the village has grown and changed and the traffic has increased. I never remember flooding ever having been as bad as it has over recent years.
EXCESS TRAFFIC AND POLLUTION: Due to local developments over the last few years the whole area has reached saturation point as far as traffic is concerned. From the A4232 junction with the M4 to Culverhouse Cross, Penarth, Sully, Barry, Wenvoe and through Dinas Powys wherever you go at whatever time of day there is traffic congestion. It can sometimes take as long as 5 minutes to exit Georges Row on to Cardiff Road towards Barry before there is a lull in the traffic from both directions. A new development of 250 houses will generate an additional 500 cars at least. Imagine what these vehicles will do to the already congested traffic system. Another set of traffic lights on Eastbrook Road at the entrance to the new development will cause even more chaos. Only last week a car overturned on the straight stretch of road into Dinas Powys just after the traffic lights and Cardiff Road had to be closed in both directions for a few hours which caused problems for the rest of the day.
ACTIVE TRAVEL The pavements are too narrow for pedestrians to walk to Eastbrook station and once you get there anyone with a pushchair or mobility problems cannot negotiate the footbridge as there is no lift to get to the opposite platform. The pavements are so narrow pedestrians cannot pass one another without stepping into the road. There is no provision for cycle paths and parking at the station is inadequate, There is no additional public transport which makes it more difficult to get around and none of the local amenities will be within walking distance of the new development. Pedestrian access to the new development via Powys Place and Powys Drive or Georges Row is completely unsuitable for anyone with mobility problems as it is on a very steep hill. Cardiff Road and Culverhouse Cross were already at capacity five years ago and there have been no subsequent road upgrades. The extra traffic will exacerbate the poor air quality outside schools which is bad for children and pedestrians alike.
NHS SERVICES Emergency services, A and E and maternity facilities will all be directly affected by the additional demand.
DOCTORS SURGERIES AND SCHOOLS These are at full capacity as a couple of the surgeries in Penarth have closed and over 1,000 new patients have been transferred to Dinas Powys The local primary and secondary schools are also at full capacity and oversubscribed,
INCREASED FLOODING The fields at the rear of Georges Row and Highfield Close are very often underwater as they take the run off from the higher ground around Llandough Hospital and Penyturnpike. As you walk through them there are marsh plants growing and you feel your feet sinking into the waterlogged ground. There was even a flock of seagulls floating on the water which had ponded in the field behind my house. The water runoff will drain into the Cadoxton Brook and cause more flooding in Dinas Powys. In all the time | have lived here I have never known flooding as bad as it has been during the last few years. A friend who lives on Southra Park has recently been issued with flood prevention barriers by the NRW. The drainage systems cannot cope with the amount of extra waste being produced by the existing developments. How much worse will it be with the waste from another big development and the Cog Road Sewerage Plant which has not been upgraded for many years so cannot cope with what is produced already.
REDUCED GREENBELT Big reductions in the greenbelt boundary will merge Dinas Powys into Llandough. These boundaries are meant to protect spaces and not adjusted to fit an agenda.
LOSS OF WILD LIFE Any further development will also damage the local wildlife. The fields at the rear of Highfield Close and Georges Row are home to all sort of wild animals and birds, we have squirrels and foxes that regularly come into the garden. We even have bats flying around on warm summer evenings and all types of birds nest in the hedges and trees, in fact we are only allowed to cut the hedges at certain times of the year so as not to disturb nesting birds. I regularly see buzzards hunting and have even seen a heron or egret in the fields. Considering how environmentally friendly we are encouraged to be these days it would be a travesty to destroy this beautiful rural area.

LOSING VILLAGE IDENTITY The population of Dinas Powys is continuously increasing and it will not be long before we lose our identity completely as a village and become part of Llandough.
The Eastbrook site was turned down last time. What has changed to make it viable now?

Additional Points to be considered
Highway objections have not been met around active travel and transport requirements.
Highways documents state that active travel and bus improvements most be produced. Persimmons has not agreed to this.
Persimmons assessment shows walking and cycling routes fail to meet required width standards and alternative routes via Seel Park and alleys are unsuitable.
Connections to Eastbrook station are not feasible due to limited road space for active travel.
Cardiff Road is too narrow for safe Active Travel.
Policy requires public transport requirements but Persimmon proposes no new bus infrastructure.
On ecology - no visible newt survey and the consultant is regarded as unreliable.
The whole area is prone to waterlogging taking run off from high ground around Llandough Hospital a Pen-y-turn Pike.
Dinas Powys cannot take any more development.
Excess traffic and pollution:
The road in the area are at saturation point. Everywhere you go you are in a traffic queue with all the new development in Sully Barry, Wenvoe Penarth and Dinas Powys and no new road improvements. another 500 vehicles at least will leave the area gridlocked. All this traffic also makes pollution levels worse for school children and pedestrians alike. None of the amenities in Dinas Powys are within walking distance of the new proposed development and with lack of public transport new residents will have to use their own transport to access them.
Active Travel. Pavements are too narrow for pedestrians to access Eastbrook station. Anyone with a pushchair or mobility problems cannot negotiate the footbridge to get from one platform to the other as there is no lift and the parking is totally inadequate.
Access to the new development via Georges Row on Powys Garden/ Powys Drive is completely unsuitable for anyone with health or mobility problems.
Increased Flooding the site is completely water logged as it takes run off from the high ground around Llandough Hospital and pen-y-turn pike. The excess water will drain which does not have the capacity to take anymore water as seen with the flooding in 2020 and subsequent years on Sunnycroft Estate. Southra Park and Cardiff Road.
NHS Services, Doctors Surgeries and Schools.
All these facilities are full and oversubscribed at present so will certainly be unable to take anymore pupils or patients.
Loss of Wildlife
The area marked for development is teeming with wildlife. Foxes and squirrels frequently come into the garden. Bats often fly around on warm summer evening and woodpeckers and many other types of birds feed from the bird table in the garden. We have seen egrets in the fields and buzzards hovering looking for small rodents in the fields. Considering how environmentally friendly we are encouraged to be, it would be a travesty to destroy this beautiful rural area.
Greenbelt and Loss of village identity.
Big reductions to the greenbelt boundary will merge Dinas Powys with Llandough and both villages will loose their identity. These boundaries are meant to protect green spaces not be adjusted to suit an agenda. The Eastbrook site was turned down for development last time. What has changed to make it viable now?

I support building houses between Dinas Powys and Llandough - there is a chronic housing shortage. But apart from this, there is also a need to fix the safety issue at the Merrie Harrier junction (Im commenting here because i couldnt work out how to comment at the replacement ldp location)

I strongly object to this proposed planning for more houses on the east of Dinas Powys on the grounds that total gridlock will be on the roads of Dinas powys - forever.
I also believe the ancient sewerage pipes will not be able to control the effluent and water run off from this site.
If this development should be permitted there will be total gridlock through Dinas Powys.
Public transport will not improve the overloaded system.
Neither will it sort Schools GPs and support networks.

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.

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 to be given to each. 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
Annex 1
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.
Annex 1
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
Annex 1
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?
Annex 1
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?
Annex 1
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
Annex 1
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.
Annex 1
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
Annex 1
• 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
Annex 1
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
Annex 1
• 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.
Annex 1
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
Annex 1
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.
Annex 1
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
Annex 1
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
Annex 1
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
Annex 1
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
Annex 1
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 lowcarbon 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
Annex 1
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.

I, and everyone one I know objects passionately about the proposed planning HG1 KS2.
The reasons are many but the following are the main objections
Traffic / Travel
There is significant congestion along Cardiff Road most of the day and also during busy times along Pen y Turnpike- so much so that Cardiff Road causes many hold ups, it is in no way feasible to have entrances to any additional housing on Cardiff road it would cause chaos. There has been no upgrade to the roads for 5 years, even though Dinas Powys has been requesting a by-pass for over a decade. Attempting to join the A4232 from Leckwith is a nightmare and there are always delays between there and Culverhouse Cross. To add an additional 300-500 cars would be farcical. Why is the Labour council focussing on Dinas Powys for building an additional housing estate when there are other sites elsewhere- it is making me question why I voted labour. How are A&E services going to be effected by the incresed traffic and population? Im on a waiting list that's already longer here than anywhere else- England has brought the waiting list times down, wales will never do this with the increased housing being built and lack ofunding being put into Health care.
Why have you made making objections to this proposal so very difficult? I take it is a ploy to prevent older or less tech savvy people from objecting?
Reduced Green belt
During Covid we were told that green spaces are imperative for mental health and emotional well being, you are destroying the very valuable green spaces and increasing everyone's stress levels by increasing pollution, road noise and volume of traffic.
Health and Education
It is incredibly difficult to get a doctor's appointment at the Health Centre since the recent additional housing in Dinas has been built. You stated that the health board said the Health centre could accommodate additional 3-500 patients, from discussing it with the doctors etc- that is not true, and they have NOT been consulted. The local primary school is currently full and would not be able to hose additional pupils- and the local High schools are also full to capacity. Where are the additional children/ young people going to be taught and by whom?
Local wildlife
I walk in the surrounding areas of Dinas, there is so much wildlife, to build additional houses would kill so much of our wildlife
Is someone taking a backhander in this, because it looks suspiciously as if it is so. We are being lied to- you are supposed to be protected us, the people not screwing us over!

KS2 - Land to the North of Dinas Powys, off Cardiff Road - Eastbrook (DNP-H1)
I am responding to this consultation as a resident of Dinas Powys. I am objecting to the proposed allocation of the Eastbrook site (land to the north of Dinas Powys) within the Vale of Glamorgan Replacement Local Development Plan (RLDP). In my opinion, this proposal is fundamentally flawed, and I have detected no evidence to suggest that anything has changed since the site was previously turned down. There remain serious concerns regarding the following: Serious infrastructure limitations; Already overburdened highways and transport capacities; The impact on the regional landscape and environment; The continuing high flood risk in the site and surrounding areas; The lack of evidence to support deliverability and viability of future housing developments
The Eastbrook site has demonstrable groundwater emergence, low-permeability soil, and overland flow routes with interactions between ground and surface water and the existing drainage systems. In addition, there has been a history of recorded significant floodings in the area not least the recent 2020 incident. The Eastbrook site has been identified repeatedly as a location of flood risk by Natural Resources Wales. Surely these issues need to be re-investigated before moving forward with housing developments.
The infrastructure support within Dinas Powys for the increase in population as a result of further housing needs urgent consideration. There is insufficient additional capacity to support the following:- A further increase in the patient base for the one local medical centre – which took on significant number of patients from Penarth recently. In fact, I understand that the centre has not been consulted; The Schools are at full capacity. Have the head teachers been consulted? ; The roads through Dinas Powys are continuously congested not least during rush hours and opening and closing hours - Surely this congestion will increase exacerbated by parking issues; Pollution especially at these critical times will increase; The state of roads – potholes – will be an even greater issue particularly during the winter months; The pavements especially around the proposed entrance sites to the Eastbrook site are already too narrow to accommodate prams and wheelchairs; Both stations are not user friendly for those with access issues, the elderly, disabled and those with young children and prams.
Unless all these issues can be addressed which to my mind is a formidable and possibly an impossible task to achieve, I request that the Vale Council remove the Eastbrook allocation from the RDLP. There is clearly no evidence to suggest that it would benefit the village of Dinas Powys but just create concerns and distress for its residents.

The land including the land Landough Hospital is built was gifted as I understand it by local person for the purpose of building the hospital in rural setting.
I object to proposal as there will be a loss of the existing country side and subsequent loss of wild life. It will bring Llandough/ Penarth/ Cardiff even closer causing greater pressure on local health services/schools/ and will create even more traffic to any already very congested Cardiff /Barry Road.
In my view this development is for commercial gain only because to the builders and thier supporters it's an ideal spot to build on.

I am appalled the consideration to build yet more houses on this site in Dinas Powys. We are already bottled in with traffic and this proposal will only increase the problem. The same access roads will be used which are extremely busy all times of the day and night, with no let up. Also with so many dwellings proposed, there is an increased chance of flooding with water running into Cadoxton River which has burst on more than one occasion flooding homes in Dinas Powys.

I have lived here for over 60 years and have seen the impact all the new houses have had on the infrastructure, apart from the loss of green spaces in the village. What was a pleasant place to live has been turned into an urban bottleneck. The village has been utterly spoiled and this proposal will just add to it.

Our doctors surgery and our local schools are already at capacity, with no plans for any new facilities. The boundary between Dinas Powys and Llandough would be even smaller, these should be protected, let alone the impact on loss of wildlife, loss of green space and trees.

I strongly object to the housing development HG1 KS2 for several reasons as stated below:
When I was a child growing up at that end of Dinas Powys I was always told that land was green belt and would not be built on. What has changed?
The main road running through Dinas Powys cannot take any more traffic. Queueing to get through what used to be a village during peak hours can take over half an hour. Is there going to be yet another set of traffic lights or will it be a different junction?
I am also very concerned as initially there is talk of 250 houses. Is that just the start or is that the final number?
Let’s just say for one minute that is the final number, we are talking in the region of 600 – 700 people, if you average 3 people per house. Please don’t tell me those people are expected to register with the already over-subscribed Health Centre. It can take days to get through for appointments or prescriptions already.
I would be more openminded about the housing development if more money is going to be spent on the services and infrastructure of what used to be a nice manageable sized village community instead of just throwing up more houses.
I have also heard that if the proposed housing does go ahead the builders assigned to the project are persimmon. I hope this is not the case as it is a know fact that the build quality is very poor.
