Welcome to the Central Coast Wetlands GIS Project!

To provide the information necessary to PROTECT, ENHANCE, and RESTORE California's Central Coast wetlands


  • Develop accurate wetland data
  • Disseminate wetland and watershed data
  • Develop consistent methodologies for the Central Coast

The Central Coast Wetlands GIS Project (CCWGIS) planning tool provides descriptive and digital spatial wetland and watershed data for California's Central Coast in an Internet-based, interactive geographic information system (GIS). Applications of this tool include information distribution, permit analysis, and identification and prioritization of wetlands for conservation projects. The tool is divided into two components based on content and may be accessed using the Interactive Mapping link.

Central Coast Framework
The Central Coast Framework establishes the GIS framework for the project area, the coastal hydrologic units (CalWater 2.2.1) from the Marin Headlands south to Point Conception. This component contains small and medium-scale data and imagery that cover the entire project area.

Morro Bay Watershed Pilot
Wetland mapping and data development protocols were tested in the CCWGIS pilot watershed, Morro Bay. These protocols will be adapted and applied in other watersheds within the project area in subsequent phases of the project. The pilot component of the planning tool contains all of the Central Coast data as well as large-scale data specific to the Morro Bay Watershed. Please access the Morro Bay Watershed Pilot link for more details regarding the pilot and the protocols and products developed.

The CCWGIS is a collaborative effort between the California Coastal Commission, the California Conservation Corps, and the Morro Bay National Estuary Program. The project is funded by a U.S. Environmental Protection Agency Wetland Program Development grant.
