Local Plan Review evidence base

In order to meet the requirements set out in national guidance, the draft Submission Local Plan is informed by detailed technical studies. These make up the Local Plan evidence base.

The studies that have been carried out for the Local Plan reflect Crawley’s locally distinctive issues, challenges and opportunities, unique to the town.

Environmental sustainability evidence supports the following Local Plan chapters:

green infrastructure and biodiversity
sustainable design and construction
environmental protection
sustainable transport

Additional evidence will be gathered and published as required.
