Habitat Conservation Plan

The Cedar River Watershed Habitat Conservation Plan (HCP) is a 50-year, ecosystem-based plan that was prepared to address the declining populations of salmon, steelhead and other species of fish and wildlife in the Cedar River basin.

Prepared under the Endangered Species Act (ESA), the plan is designed both to provide certainty for the City of Seattle's drinking water supply and to protect and restore habitats of 83 species of fish and wildlife that may be affected by the City of Seattle's water supply and hydroelectric operations on the Cedar River.



Habitat conservation planning is a tool to achieve both species protection and water supply protection. Learn about what actions we're taking to improve species and habitats, HCP history, oversight committees, how we work with other organizations, and more..

Many of the HCP's benefits for fish and wildlife can only be realized over a long period of time. For example, efforts to restore stream and forest habitat typically take many decades before results are evident
