Environmental Improvements at the Southsea Coastal Scheme The Southsea Coastal Scheme in Portsmouth is the UK’s largest local authority led coastal defence project. Spanning 4.5km, the scheme reduces the risk of coastal flooding and erosion for over 10,000 homes and 700 businesses. Split into six sub-frontages, the construction is being delivered in phases. Sub-frontage 4 construction was completed in May 2024, inclusive of a range of environmental improvements, such as the installation of 45 precast tidepools, 55 rock-munched granite rockpools and pre-colonised seed rock to encourage and enhance the marine biodiversity of the new coastal structure. Funding for these initiatives was obtained from the Water Environment Improvement Fund and Local Levy.
