ARL10: Flood Risk Management
Development proposals will be expected to:
- be designed and constructed so that the overall level of flood risk within the parish will not increase;
- provide appropriate surface water drainage which may include permeable driveways and parking areas, water harvesting and storage features, green roofs and/or soakaways; and
- provide open culverts where practicable.
Development will not be permitted in flood attenuation areas where that development would reduce the ability of these areas to alleviate flooding.
Proposals will need to demonstrate that development has avoided the loss of open water courses through culverting with existing culverted sections opened up where viable.
Any new development must have adequate receiving surface water drainage, i.e. drains, culverts and definable water courses, in consultation with the Environment Agency, Local Authority, Internal Drainage Boards, Highways and water companies.
It must also ensure that appropriate measures are secured to ensure the adoption and ongoing maintenance of any flood prevention measures.
The discharge of surface water to public surface water sewers would only be acceptable where it has been demonstrated that there are no feasible alternatives.
Infiltration devices should allow at least 1m freeboard between the bottom of the device and the seasonal ground water table.
