Flood Risk & Ecology
Flood Risk
The proposed site is identified as lying outside of the fluvial and tidal flood risk zone, according to the Environment Agency’s (EA) published flood map for planning.
The EA information indicates that the level of flood risk to the site corresponds to a Flood Zone 1 – low probability of flooding. This flood zone has less than a 1 in 1000-year annual probability of flooding.
Drainage
Surface Water
Surface water run-off from the new development should be managed via the design of a sustainable drainage system (SuDS). The possible drainage options considered for the site include the use of infiltration methods and discharging to a local watercourse or public sewer network.
The preferred method for the disposal of surface water flows is via the use of infiltration techniques, including attenuation basins, as shown on the proposed illustrative masterplan.
It is proposed to incorporate a variety of SuDS features throughout the development proposals, which will provide ecological and water quality benefits.
Foul Drainage
A new foul water drainage network will be constructed to accommodate the requirements of the proposed development. The new network will collect and convey foul water discharge from the development to the existing public sewer network.
Ecology
The site is currently undergoing ecological surveys to ensure any potential environmental impacts are fully understood. An initial walkover survey found no significant ecological constraints.
A habitat survey has also confirmed that the existing vegetation is of low ecological value, and no further surveys for protected species are required. Overall, the site is considered to be of limited ecological importance.
