PL 2 Flood risk

The development of appropriate sites within flood zones 2, 3a and 3b in the Wandle Valley and the Thames riverside will be permitted in principle in terms of the Sequential Test. Appropriate sites are those which are allocated in the Site Specific Allocations Document and have been subject to the Sequential Test as set out in the Council’s Flood Risk and Development Sequential Test Report (2015).

Where development is permitted within flood risk areas it must demonstrate that where possible, it will reduce fluvial, tidal, surface water and groundwater flood risk and manage residual risks through appropriate flood risk measures. Tidal flood risk will be managed in accordance with the measures set out in the Thames Estuary 2100 (TE2100) Plan 2012.

A site specific Flood Risk Assessment will be required for proposed development of 1 hectare or greater in flood zone 1, all proposed development (including minor development and change of use) within flood zones 2 and 3 (3a and 3b), and any development at risk from other sources of flooding. A Flood Risk Assessment should take account of the Strategic Flood Risk Assessment, the Local Flood Risk Management Strategy, the Surface Water Management Plan and the Preliminary Flood Risk Assessment.

Site specific Flood Risk Assessments should consider flooding from all sources including tidal, fluvial, surface water, groundwater, sewer and artificial sources.
