Coastal management is about maintaining balance in coastal communities. It is a process that takes into consideration many factors, including development, the natural environment, coastal commerce, hazardous weather impacts, aesthetics, quality of life, water quality, erosion, and more.

This page profiles the coastal management organizations, federal and state, operating under the Coastal Zone Management Act and facts and figures about coastal management in Guam.

Habitat Focus Area

Guam’s Manell-Geus Habitat Focus Area is home to the island’s only shallow water lagoon and features fringe reefs, mangroves, and seagrass beds. Poor water quality, among other factors, threatens this ecosystem. Plans to improve this habitat from its declining conditions are underway.

NOAA's Digital Coast provides data, tools, training, and information resources for Guam’s coastal management community. See how Digital Coast is being used in this state.
