Dear Mr Barber
Publication Draft, Local Plan
Focused Consultation
Thank you for consulting the Environment Agency in relation to the above proposals.
We have the following comments to make in relation to reference to 1 and 4 specifically:
Ref 1 : E4 Land at Stratford Road, Warwick
Modification includes the addition of a new site allocation Ref: E4 Land at Stratford Road Warwick. Size 11.5ha and Uses B Class.
This site is partially within Flood Zone 3. A level 2 Strategic Flood Risk assessment (SFRA) should be undertaken by a suitably qualified technical expert or engineer.
The floodplain in this location is derived from generalised modelling techniques, any development proposed on this site will need to be supported by hydraullic modelling to confirm the extent of the appropriate developable land and inform the design and layout of the development.
Where culverted watercourses pass through or boundary the site, opportunities must be sought for de-culverting for flood risk management purposes. Any culverts which remain a blockage risk to this site will require further modelling to ascertain the risk areas associated with culvert blockage. Mitigation measures must be intergrated within the design and layout of the development.
This is in addition to the requirements as outlined within FW1 Section 5.127
Urban Drainage: Section FW2 Sustainable Urban Drainage.
In addition to adhering to the requirements set out in the above policy, opportunities should be explored within the development boundaries to reduce the existing run off rate to the greenfield rates of discharge in line with the emerging local plan.
Ref 4: DS11 H39 - Opus 40, Birmingham, Warwick
A level 2 SFRA is required. The site lies adjacent to the Saltisford Brook, further investigation which may include Hydraullic Modelling will need to be undertaken to establish whether a fluvial flood risk exists to the site from this source. No Flood Zones currently exist in this location.
All built development including drainage features should be sited outside of the 100 year climate change fluvial outline.
The Flood Risk assessment (FRA) must demonstrate that safe access to and from the site can be achieved for emergency vehicles up to and including the 100 year climate change fluvial event.
In Conclusion
Further work should be undertaken to ensure that sites 1 & 4 can be developed by undertaking a Level 2 SFRA.
The site allocations should state the relevant policy recommendations from the emerging local plan.
