Our approach to managing drainage is to limit run-off from the entire site. To achieve this, we will create Sustainable Urban Drainage Systems (SUDS), which will safely store and drain away water, creating ecological habitats.
We are aware that a small section of the Airfield is currently draining northwards towards the Highfields Road roundabout, and then on towards Bar Hill. To reduce current drainage problems in this area, we will improve the existing drainage ditch to the north of the existing site access road and enhance available surface water storage capacity through the proposed SUDS scheme. We expect that SUDS will result in a significant reduction of surface water runoff rates to the downstream Bourn Brook catchment, compared to existing rates.
