GMCA 2235 - Spatial Development Strategy

Integrated Impact Assessment (IIA) - Greater Manchester Spatial Development Strategy The Greater Manchester Combined Authority (GMCA) is looking to commission an Integrated Impact Assessment (IIA) to support the preparation of a Spatial Development Strategy (SDS) for Greater Manchester. Statutory SDSs were introduced through the Planning and Infrastructure Act 2025. The SDS will provide a strategic planning framework for the city-region over a 25-year plan period and once adopted, it will form part of the development plan for Greater Manchester’s local planning authorities (Bolton, Bury, Manchester, Oldham, Rochdale, Salford, Stockport, Tameside, Trafford, and Wigan). It is a high-level, statutory planning document that will set strategic policies covering growth, housing, employment, infrastructure, the environment, and transport. Greater Manchester Combined Authority is therefore undertaking an expression of interest for the following: - Integrated Impact Assessment (IIA) on the forthcoming Greater Manchester Spatial Development Strategy, comprising of: - Sustainability Appraisal (SA) incorporating the requirements of a Strategic Environmental Assessment) - Health Impact Assessment (HIA); and - Equality Impact Assessment (EqIA). IIA for Greater Manchester Spatial Development Strategy: - IIA Scoping Report - IIA of spatial options/ reasonable plan alternatives - IIA of whole SDS Plan - IIA of any proposed modifications to the SDS, as result of statutory consultation and preparation of Final IAA report for SDS submission
