Sur 2 - Flood Risk
Aim:
To encourage housing development in low flood risk areas, or to take measures to reduce the impact of flooding on houses built in areas with a medium or high risk of flooding.
Credits: Max. 2
Assessment Criteria:
Up to 2 credits are awarded where the assessed dwelling is located either in an area of low annual probability of flooding, or where a Flood Risk Assessment (FRA) shows that appropriate measures have been taken to ensure safe access and escape routes and flood resilient and resistant construction.
Our Flood Risk Services:
We offer three levels of FRA reporting and will advise on which is most appropriate for your development.
FRA Level 1 - Screening Study
-
An initial assessment of the site to identify existing flooding or surface water management issues that may warrant further consideration.
-
Production of a brief report demonstrating CSH compliance.
-
Included in our Surface Water Run-off Appraisal.

FRA Level 2 - Scoping Study
-
Qualitative appraisal of flood risk posed to site and potential impacts the development will have on flood risk elsewhere.
-
Production of a Preliminary FRA report including the possible measures to reduce flood risk and likely outcome of a full FRA including a site layout showing the extent of predicted flood water inundation.
|
FRA Level 3 - Detailed Study
-
Quantitative appraisal and production of a FRA report possibly including catchment analysis, hydraulic calculations and flood mitigation measures. The contents required will be established after Environment Agency consultation.
-
This may include the use of 1D/2D Flood Modelling for the quantitative appraisal of the potential flood risk to site and offsite flood risk impacts.
-
If requested, we also have the capability of producing high quality 3D animations of the predicted flood and 3D digital terrain maps showing flooding at the peak flood level.
