Site Allocation SA01: Land South of Ermyn Way, Ashtead

EXPECTED YIELD – 250 dwellings and two gypsy and traveller pitches
PROPOSED USE – Residential and public open space
SIZE – 21.8ha


  1. The site layout shall maximise retention and safeguarding of existing mature trees, tree belts and areas of woodland and any species of botanical interest which are identified within the field margins, and incorporate those features in a coherent landscaping strategy for the site.
  2. At least 8.3ha of public open space shall be provided in the eastern part of the site, which is within the Green Belt, to be retained in perpetuity and managed in a manner which respects the wider rural landscape and supports biodiversity within and around the site.
  3. The design and layout shall create clearly defined boundaries between the edge of the site and the Green Belt using physical features which are recognisable, likely to be permanent and consistent with the character of the surrounding environment.
  4. A programme of archaeological investigations must be undertaken to determine the likelihood of heritage assets being present within the site and secure appropriate recording and/or preservation of such assets, appropriate to their archaeological significance.
  5. Development shall incorporate mitigation measures such as site zoning, physical barriers, good design and building layout to ensure that future occupiers are not subject to a significant adverse level of noise disturbance, both within buildings and externally. Noise-sensitive rooms should be situated away from the motorway, to be shielded from noise, where necessary. Enhanced fenestration glazing and mechanical ventilation should not be relied on in isolation, but may form part of a package of mitigation measures, where it is not possible for site layout and other design measures to achieve the required level of mitigation.
  6. The development shall incorporate open space and equipped play space in accordance with policy EN11, laid out in a manner which provides easy access for residents of the development and is also accessible to the general public.
  7. Access improvements shall be carried out to the junction serving the site from the adjacent highway.
  8. The development shall incorporate affordable housing that meets the requirements of Policy H2 in terms of the proportion, dwelling mix and tenure. Affordable housing should be integrated within the scheme with equal access to on-site communal facilities.


  1. The development should contribute towards improvements to the local highway network, to mitigate the impact of traffic growth on existing roads and junctions, including the junction of Ermyn Way, Grange Road and Leatherhead Road (A24) and the surrounding road network.
  2. Proposals for green infrastructure and public open space should incorporate opportunities for biodiversity enhancement, including creation of new green corridors through the planting of appropriate native woodland species along the eastern boundary of public open space, and the creation of green corridors and habitat areas.
  3. Opportunities should be taken to connect the site, including the public open space, with the existing public rights of way network in order to provide enhanced recreational opportunities for residents of the proposed dwellings and the wider population.
  4. Opportunities should be explored to enhance pedestrian and cyclist connectivity to and from the site, in order to facilitate safe, sustainable travel to local shops, schools and other services.
