Which agency manages the coastal zone up to 3 miles out to sea?

The agency that manages the coastal zone up to 3 miles out to sea is the California Coastal Commission. This Commission was established to protect and enhance California's coastal resources, including beaches, ocean waters, and marine habitats. Its role includes overseeing development along the coast, ensuring public access to coastal areas, and preserving the environment for future generations. The jurisdiction extends to the coastal zone, which is defined as the area from the mean high tide line seaward to three nautical miles, emphasizing the Commission's authority over both land-use planning and marine resource management.

In California, the Coastal Commission plays a vital role in balancing the interests of development with environmental protection. It reviews coastal development permits and works to implement the California Coastal Act, which aims to maintain the coastline's natural beauty while providing for responsible use. This framework is fundamental to maintaining the ecological integrity of California's coastal areas, making the Coastal Commission the primary agency responsible for managing the coastal zone.
