Milton Common is the second stage of the multi-million-pound Flooding and Coastal Erosion Risk Management scheme being developed across the north of Portsea Island, from Mountbatten Centre round to Milton Common. The overall project will reduce the risk of coastal flooding and erosion and provide the critical infrastructure the city will need over the next 100 years (6). As the second phase, Milton Common included the instalment of a new rock revetment as a plans defence, the creation of a coastal path and three new earth bunds with new footpaths (6). The work has also included the demolition of Great Salterns Quay and restoration of the natural mudflat habitat (2,4). The fully completed scheme will significantly reduce the risk of coastal flooding to Milton Common and the local area over the next 100 years; it will offer protection against a 1 in 500-year flood event providing one of the highest standards of flood protection in the UK outside of London (6).

- Climate change adaptation
- Water management (SDG 6)
- Flood protection
- Coastal resilience and marine protection (SDG 14)
- Coastal protection / hazard mitigation
- Green space, habitats and biodiversity (SDG 15)

Focus
Coastal landscape management or protection
Project objectives
1. Deliver a combined, efficient and comprehensive coastal management service (1)
2. Reduce the risk of coastal flooding and erosion, as well as the developed and natural environment. (1)
3. Post-construction, the area to be enhanced through an extensive replanting programme - increase the diversity of plants in the area, improving the current ecosystems and habitats for wildlife. (5)
4. Construct 1.5km of setback earth embankments and rock revetment structure (1)
Implementation activities
- Installation of a new rock revetment, constructed from granite Larvikite delivered from Norway (6)
- Creation of a coastal path and three new earth bunds with new footpaths (6)
- Demolition of the old Great Salterns Quay, so the area can return to its natural mudflat habitat. (4,6)
- Installation of a new section sea wall to provide a continued level of defence along the coastline, following the removal of the quay (6)
- Landscaping of both the Milton and Anchorage Park sites has started with native trees, shrubs, grasses and wildflowers being planted.(3)
