Chichester DC's New Nitrate Neutrality Statement


The Latest on Nitrate Neutral Development

In our last Planning Wise, we mentioned that Havant Council had recently adopted policy guidance to ensure any new housing development in its borough was ‘nitrate neutral’ to limit further increases in nutrient discharge to Langstone Harbour, a Special Protection Area of European significance. (See article on Local Gov website here)

And as we predicted, Chichester District has now decided to adopt the same approach to developments that discharge to Chichester Harbour.

A nitrate neutrality statement must therefore now be submitted with any application for:

1) Residential developments resulting in a net gain in the number of dwellings, and

2) Commercial development resulting in an increase in overnight stays where wastewater would discharge to Appledram, Bosham or Thornham Wastewater Treatment Works (WwTW) OR a means of non-mains drainage within the Chichester Harbour fluvial catchment.

Natural England's assessments during 2019/20 suggest that more than 3000 hectares of the intertidal parts of Chichester Harbour are now in an "unfavourable - declining" condition.  

Water quality is a contributing factor to the build-up of excess nutrients in the Harbour causing eutrophication (algal growth) which impacts on the Harbour's ecology and conservation.
