Watershed Management Plan

Mission Statement

The mission of the Watershed Management Plan (WMP) is to restore a healthier balance between the urban environment and the natural ecosystem, including the Santa Monica Bay, by reducing the pollution in urban runoff, reducing urban flooding, and increasing water conservation, recreational opportunities, open space, and wildlife and marine habitat.


Santa Monica's Watershed Management Plan, completed in April 2006, is a dynamic plan to move the City toward a more sustainable management of its local water resources and water quality protection and improvement of the Santa Monica Bay.
