NYC are in the process of drawing up a draft plan for developments in the area from 2028.  

It will cover housing, employment, retail, leisure, energy and biodiversity.  HBC produced something similar in 2018, now being 'followed', particularly regarding housing.

NYCC have produced a document 'Call for Sites', encouraging land owners and agents to put forward sites for consideration. Parish Councils have recently been circulated, a copy of which can be viewed here or seen below.  It's important that those affected follow what is happening and get involved in the process because once land is designated for certain uses in a local plan, it makes it more difficult to object to planning applications which are in line with the plan.
