The Cape Cod Commission, established in 1990, is charged with furthering conservation, balanced economic growth, water quality protection, provision of adequate capital facilities, development of adequate fair affordable housing, and preservation of coastal resources and historical, cultural, archaeological, architectural, and recreational values. The Commission adopted a Regional Policy Plan in 1991 to guide land use throughout the county; the plan is reviewed and amended as needed at least every five years. In the 2012 amendment, sea level rise is reflected throughout in both minimum performance standards and best development practices. The plan acknowledges that projected sea level rise will increase flooding, storm surge, and erosion that threaten coastal infrastructure, habitats, and communities, and that coastal planning will require spatial design. For example, the plan requires that new development or redevelopment not impede the landward migration of coastal habitats (e.g., beaches, dunes, salt marshes). It also requires that new buildings be elevated above Base Flood Elevation, and that setbacks from coastal banks are calculated at least 70 times the average annual erosion rate to protect residential coastal structures.
