The Sustainability Appraisal, Strategic Environmental Assessment (often called SA/SEA), and Habitat Regulations Assessment (HRA) are tests of the Local Development Plan (or Strategic Development Plan). They look at the effects of the plan on the environment, social, economic and cultural well-being, as well as the use of the Welsh language. The SA/SEA and HRA process runs alongside the Local Development Plan process, and you can comment on the SA/SEA and HRA themselves.
