Site constraints 7

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.
In flood zones plus climate change
Inside the extent flood zones 2 and 3 could reach with climate change: the Central allowance for the 2080s on rivers, the Upper End allowance for sea level rise to 2125. From the sea. Defences are not counted.
The Environment Agency flood map for planning. Councils use it to decide when a flood risk assessment and the sequential test are needed. It is indicative and does not show whether a particular property will flood.
Flood map ↗
National infrastructure project 476 m away: AQUIND Interconnector
The site is 476 m from the project boundary. Electricity line, awaiting the Secretary of State's decision. Also within 2 km: Hampshire Water Transfer and Water Recycling Project (accepted for examination, 1520 m).
Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.

Radon affected area, class 2; Special area of conservation 458 m away: Solent Maritime; SSSI 458 m away: Langstone Harbour SSSI; Inside the Portsmouth built-up area.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site
