The Green Infrastructure Supplementary Planning Document (SPD) reflects and expands upon the open space, biodiversity and countryside policies in the Crawley Borough Local Plan, providing supporting guidance to assist applicants in meeting the Local Plan requirements. This includes the policies in relation to:

• the green infrastructure network
• trees
• open space
• biodiversity (including Biodiversity Net Gain and Urban Greening Factor)
• Countryside and High Weald National Landscape

The Green Infrastructure Supplementary Planning Document (SPD) was adopted on 1 June 2026 following public consultation which took place from 26 February 2026 until 26 March 2026.

The SPD forms part of the development plan for Crawley and is an important consideration in determining planning applications. It replaces the Green infrastructure SPD 2016.
