Supplementary planning documents (SPDs)
Our supplementary planning documents (SPDs) provide extra guidance about the policies in our development plan.
Section 106 and CIL SPD
Our Section 106 and CIL SPD provides detailed guidance on the use of Section 106 planning obligations and the community infrastructure levy.
It sets out:
- The requirements for mitigating any impacts of development using Section 106
planning obligations and CIL. - How Section 106 (S106) planning obligations arise and are secured.
This was adopted by cabinet on 7 July 2025 and replaces the 2015 Section 106 and CIL SPD.
