Phase 1 land quality assessments
We require a phase 1 land quality assessment to be submitted with all planning applications for:
- Any development where the site is known to be contaminated
- Any development where contamination is suspected for all or part of the site
- Any development sensitive to contamination, such as residential, schools, nurseries and allotments
More information is available about the sites that require land quality assessments on our planning pages.
Requirements of phase 1 land quality assessments
The desk study should include as a minimum:
- site description and location (including a clear map)
- historical information about the site
- surrounding area current use and historical uses
- conceptual site model identifying potential sources, pathways and receptors
- walkover survey
- geology
- hydro geological information
