Site constraints 13

Flood zone 2, rivers and sea
Medium chance: between a 1 in 100 and 1 in 1,000 annual chance from rivers, or 1 in 200 to 1 in 1,000 from the sea. Any development here needs a flood risk assessment. Defences are not counted.
The Environment Agency flood map for planning. Homes in zone 3 must also pass the sequential test. Surface water flooding is a separate map.
Flood map ↗
Nutrient neutrality catchment: Solent: Includes Chichester and Langstone Harbours SPA/Ramsar, Solent and Southampton Water SPA/Ramsar, Solent Maritime SAC, Portsmouth Harbour SPA/Ramsar
New homes and overnight accommodation must show nutrient neutrality before approval.
Natural England advice: extra wastewater in these catchments harms protected habitats, so schemes must offset their nutrient load, usually through credits.
Bishops Waltham conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
