Site-Specific Flood Risk Assessment: CHECKLIST
Paragraph: 068 Reference ID: 7-068-20140306
|1 Development description and location|
|a. What type of development is proposed (e.g., new development, an extension to existing development, a change of use etc.) and where will it be located?|
|b. What is its flood risk vulnerability classification?|
|c. Is the proposed development consistent with the Local Plan for the area?
(Seek advice from the local planning authority if you are unsure about this).
|d. What evidence can be provided that the Sequential Test and where necessary the Exception Test has/have been applied in the selection of this site for this development type?|
|e. Will your proposal increase overall the number of occupants and/or users of the building/land, or the nature or times of occupation or use, such that it may affect the degree of flood risk to these people?
(Particularly relevant to minor developments (alterations & extensions) & changes of use).
|2. Definition of the flood hazard|
|a. What sources of flooding could affect the site?|
|b. For each identified source in box 2a above, can you describe how flooding would occur, with reference to any historic records where these are available?|
|c. What are the existing surface water drainage arrangements for the site?|
|a. Which flood zone is the site within? (As a first step, check the Flood Map for Planning (Rivers and Sea) on the Environment Agency’s web site)|
|b. If there is a Strategic Flood Risk Assessment covering this site (check with the local planning authority). Does this show the same or a different flood zone compared with the Environment Agency’s flood map? (If different you should seek advice from the local planning authority and, if necessary, the Environment Agency).
|c. What is the probability of the site flooding, taking account of the maps of flood risk from rivers and the sea and from surface water, on the Environment Agency’s web site,and the Strategic Flood Risk Assessment, and of any further flood risk information for the site?
|d. If known, what (approximately) are the existing rates and volumes of surface water run-off generated by the site?
|4. Climate change|
|How is flood risk at the site likely to be affected by climate change? (The local planning authority’s Strategic Flood Risk Assessment should have taken this into account. Further information on climate change and development and flood risk is available on the Environment Agency’s web site.
|5. Detailed development proposals|
|Where appropriate, are you able to demonstrate how land uses most sensitive to flood damage have been placed in areas within the site that are at least risk of flooding (including providing details of the development layout)?|
|6. Flood risk management measures|
|How will the site/building be protected from flooding, including the potential impacts of climate change, over the development’s lifetime?|
|7. Off site impacts|
|a. How will you ensure that your proposed development and the measures to protect your site from flooding will not increase flood risk elsewhere?|
|b. How will you prevent run-off from the completed development causing an impact elsewhere?|
|c. Are there any opportunities offered by the development to reduce flood risk elsewhere?|
|8. Residual risks|
|a. What flood-related risks will remain after you have implemented the measures to protect the site from flooding?|
|b. How, and by whom, will these risks be managed over the lifetime of the development? (E.g., flood warning and evacuation procedures).|
