Eureka Area Watersheds Storm Water Resource Plan

The Eureka Area Watersheds Storm Water Resource Plan (EAWSWRP) is a regional storm water planning document that facilitates a watershed-based analysis of storm water issues and opportunities within select watersheds that drain to Humboldt Bay (Project Area Map). The EAWSWRP is guided by a Technical Advisory Committee (TAC) made of staff from the City of Eureka, County of Humboldt, Humboldt Community Services District, and the North Coast Regional Water Quality Control Board.  The EAWSWRP is intended to maximize cooperation and collaboration among state, regional and local agencies, and nongovernmental organizations during the development and implementation of storm water projects, in addition to providing guidance for the identification and prioritization of storm water projects.


Need and Purpose of a Storm Water Resource Plan

A Storm Water Resource Plan (SWRP) is a planning document that is now required as a condition of receiving funds for storm water and dry weather runoff capture projects (Water Code section 10563 (c)(1)). This requirement applies to Proposition 1, which authorized $200 million in grants for multi-benefit storm water management projects. The City of Eureka and surrounding Humboldt County areas in the watershed planning area are required to develop a SWRP to receive Proposition 1 storm water grant funding.

Traditional approaches to storm water management have focused on conveyance to surface waters without providing treatment of runoff. These traditional approaches can cause detrimental impacts to downstream surface water bodies including hydromodification, destabilization, erosion, and pollution. The impetus of a SWRP is to prioritize projects that address the water quality impacts from storm water discharges while providing multiple benefits, such as public education and ecological enhancement within a local watershed.  Projects can range from small retrofits such as standardized parkway curb cuts and tree wells in public rights-of-way to creation of constructed natural wetlands and/or installation of underground vaults that infiltrate or store captured runoff, for more examples see the Project Benefits and Examples Table.

How to get involved: 

The development of the EAWSWRP is an opportunity for stakeholder and public input on storm water management in the Project Area Watersheds. There are several ways you can get involved:

  • Submit a Storm Water Project for Inclusion in the EAWSWRP: Submit a project recommendation, using the Project Request Form, to be considered for inclusion in the EAWSWRP.  Project solicitation will close on February 28, 2018.
  • Public Opinion Survey: Fill out the public opinion survey developed by the NCSC, which will be circulated throughout the Humboldt County area in spring 2018 and will also be available at
  • Attend Meetings: Attend and participate in stakeholder presentations and/or public meetings; check this web page for schedule updates.
    • The first stakeholder presentation was held at the fall 2017 general meeting of the Humboldt Bay Initiative (HBI) on Tues. Dec. 12th from 11:30am-12pm at the Humboldt Bay Aquatic Center.
    • The second stakeholder presentation was held at the North Coast Stormwater Coalition's December meeting on Wed. Dec. 13th from 9-9:30am in the Arcata City Hall Council Chambers.
    • The stakeholder presentation slides can be viewed here: EAWSWRP Stakeholder Presentation Dec 2017
  • Provide feedback on draft sections of the EAWSWRP:  Note that these are not standalone documents and will be incorporated into the EAWSWRP.  Please include feedback in an email to .  Feedback on draft sections will be accepted until May 2018.  The draft Plan will be circulated beginning in June 2018.
