The proposed development site is outside of the flood zone (potential flooding for river and sea) with all drainage infrastructure outside.

Captured rainfall will be directed towards localized watercourses with treatment and attention en route. It is proposed to introduce grassed swales alongside new roads with rainfall landing on parking areas captured at source and slowly released towards a large dry attenuation basin as will the swales.

The dry (when not raining) attenuation basin will hold back the captured rainfall and slowly release the water into the watercourse at a rate that will be agreed with the Local Flood Authority following local and national guidance.

Drainage (SuDS) features have been carefully thought of to keep in with the local setting and not draw the attenuation away from the proposed development itself.
