City Involvement

About the Program

For many years, the City has been committed to improving the quality of urban runoff through the development of a proactive, comprehensive Stormwater Management Program that recognizes Arcata's unique position in the Humboldt Bay watershed and the need to protect our important natural resources.

North Coast Stormwater Coalition

North Coast Stormwater Coalition 


The City of Arcata participates in the North Coast Stormwater Coalition, a group that works collaboratively with Northern California city and county governments to reduce stormwater pollution and protect local waterways. Coalition members include stormwater management staff from the participating cities of Eureka, Arcata, Trinidad, Fortuna, Fort Bragg, and Yreka, the counties of Humboldt and Mendocino, and Cal Poly Humboldt, as well as, local, state, and federal agency representatives, non-profit organizations, tribes, consultants, engineers, and interested community members. 

Low Impact Development

The General Permit demands local agencies that development projects to comply with post-construction stormwater requirements based on “low impact development” (LID) standards. 

Low-impact development, or LID, is an approach to managing stormwater that aims to capture, treat, and help stormwater runoff seep slowly into the ground in a way that mimics how water passed through the area before development. LID accomplishes this by incorporating features throughout a project site like tree plantings, rain barrels at the end of roof gutters and planted buffer strips. These small-scale improvements intercept and slow stormwater runoff so creeks and streams won’t suffer erosion and flash-flood flows during storms.

Some LID features also process pollutants like motor oil as the water sinks into the soil, making the pollutants less toxic. Without LID improvements, stormwater often flows swiftly into stormdrains, carrying untreated water directly into creeks and Humboldt Bay.
