Flood Storage Areas
What this layer shows
509 engineered flood storage areas and washlands mapped by the Environment Agency. NOT the same as Flood Zone 3b: the functional floodplain is defined by the local planning authority in its Strategic Flood Risk Assessment, and the EA does not publish it as a separate boundary.

Planning
The constraints that shape a red line: SSSI Impact Risk Zones, Green Belt, the Flood Map for Planning zones and storage areas with present-day rivers-and-sea risk, Agricultural Land Classification (both the provisional national map and the more reliable post-1988 surveys), nutrient neutrality catchments, National Parks, National Landscapes and Local Nature Recovery Strategy areas. Useful for a constraints plan or an early feasibility check before any ecology is commissioned.
Flood
Flood zones, surface water, defences and what has flooded before.
