Site constraints 6

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.
National infrastructure project 592 m away: Hampshire Water Transfer and Water Recycling Project
The site is 592 m from the project boundary. Dam or reservoir, accepted for examination. Also within 2 km: AQUIND Interconnector (awaiting the Secretary of State's decision, 901 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.
Planning Inspectorate project page ↗
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
Radon affected area, class 2; SSSI 362 m away: Portsdown SSSI; Inside the Portsmouth built-up area.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
