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.
Article 4 direction
HMO. Named permitted development rights are withdrawn here.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.
Also on the record
