Site constraints 15

Surface water flood riskAerodrome safeguarding zoneFlood zone 3Flood zone 2Unexploded ordnance risk
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.
New Forest National Park
The park authority decides applications here. Great weight to conserving the landscape; major development restricted.
Landscape, scenic beauty and wildlife carry great weight, and major development is only allowed in exceptional circumstances.
2 Article 4 directions
Article 4 Direction Np New Forest Campsite · Article 4 Direction Np New Forest Recreational Campsite. Named permitted development rights are withdrawn here.
An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.
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 rivers. 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 ↗
Public footpath 21 m away
Matters where it crosses or adjoins the site: obstructing a path without a diversion order is an offence, and work cannot start until the order is confirmed.
Compiled from highway authority data, not the legal definitive map. A few authorities have not published, so no path shown is not proof there is none.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.

Checked on 6 October 2026. Historic England, the Environment Agency, Natural England and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
