Mitigation required for heavy constraints. Standard information required at a planning stage.
"1.] At risk of surface water flooding?: Yes
* 3.33% AEP Event [Extent]: No flooding present
* 3.33% AEP Event [Depth]: No flooding present.
* 1.0% AEP Event [Extent]: No flooding present
* 1.0% AEP Event [Depth]: No flooding present.
* 0.1% AEP Event [Extent]: Minor flooding|Moderate flooding
* 0.1% AEP Event [Depth]: 0.00 - 0.15cm.
2.] Internal & external flooding?:
* On-site: No
* Within proximity to site (~500.00m): Yes - Internal Flooding|Yes - External Flooding
3.] Watercourses [Online ordinary watercourses or mains rivers]?:
* On-site: No
* Within proximity to site (~100.00m): No
4.] Surface water sewer systems?:
* On-site: Yes
* Within proximity to site (~100.00m): Yes
5.] Source Protection Zone?: Source Protection Zone 3
6.] Internal Drainage Board?: No IDB referenced
7.] The site predominantly has superficial deposits of DIAMICTON. Comments on infiltration potential are dependent on a complete geotechnical investigation, including BRE365 Soakaway Testing. Where possible, surface water infiltration should be utilised." "The on-site flood risk contributes to a flow path in the 0.1% AEP event along the eastern side of the site. Flow lines indicate this flood water flows south off of the site, contributing to a larger flow path south of the site. We advise this must be considered in the site assessment.

A large area of the site is unaffected by flood risk and has the potential to be developed."
