Where possible, surface water infiltration should be utilised." "The on-site flood risk is a moderate flow path in the 0.1% AEP event, dissecting the site south-north in the west of the site. Flow lines indicate this flood water flows north off of the site, contributing to a larger flow path west and north 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."

Part of the on-site flood risk forms a moderate flow path in the 0.1% AEP event, dissecting the site west-south in the west, southwest and centre 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. The on-site flow path forms a curve shape. 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."
