Understanding the Framework of Coastal Zoning

Zoning laws are local ordinaces that divide a difficinality into districts andregulate land use, building size, density, and placement. In coasustal areas, these regulations serve a dual intence: manaving development and providing natural systems. Typical coasustal zoning suppresses included de building setbacks frem mean hight and density limits, and prohibitions on certain structures like seawalls or groins.

Te static nature of traditional zoning colides with thee dynamic reality of coastrides. Erosion, accretion, and storm surgere alter shorelines faster than codes can be updated.
