We improve the storm drain system to reduce flooding, improve water quality, and increase fish passage. Our inspection and maintenance program prevents pollutants and debris from entering waterways.
Our partners know that there is more to surface waters than what is on the surface. Watershed health monitoring, water cleanup and restoration projects, and public health water monitoring keep our waters safe for recreation and shellfishing.
Our many community programs help citizens understand their connection to water quality. Programs like the Rain Gardens and More cost share, Backyard Habitat Restoration, and Agriculture Technical Assistance help property owners improve their homes while protecting our watersheds.
Careful planning on a watershed scale helps to make sure that people, fish and wildlife continue to have abundant, clean water. We collaborate with community partners to identify and apply strategies for protecting our water resources while making sure we have needed growth.

Stormwater Management Program (SWMP) for NPDES
Kitsap County is expected to develop a Stormwater Management Program (SWMP) that includes all the required activities, implement those activities within the required timeframes of the Permit term, and submit annual reports to the Washington State Department of Ecology each year to document progress toward completing program implementation.
Stormwater Comprehensive Plan and Stormwater Management Action Plan (SMAP)
To meet the planning requirements of the 2019-2024 NPDES Permit, Kitsap County has developed its Stormwater Comprehensive Plan and SMAP to target priority watersheds and coordinate programmatic planning efforts.
The Stormwater Strategic Plan is designed to serve as a roadmap for the Division's decision makers to put into operation a proactive, compliant and sustainable stormwater management philosophy. The goals and objectives in this plan guide our annual work plans and illuminate a course that focuses on maintaining compliance and implementing policies that not only protect our precious natural resources but also enhance Kitsap residents' quality of life.
Kitsap County welcomes comments on our Stormwater Management Program, Comprehensive Plan and Management Action Plan as part of the public input process.
