Sustainability Appraisal Integrated Impact Assessments. 1.5.1 For the LDP, the Council must consider establishing the Sustainability Appraisal (SA) baseline, which includes the requirements of the Strategic Environmental Assessment (SEA) and reconsideration of the validity of the SA framework for the Joint Local Development Plan. If there are parts of the SA framework for the current LDP that are still relevant these will be updated for the new LDP.
