Stormwater Management Standards On December 13, 2002 (with a technical correction on December 20), Jefferson County adopted the Stormwater Management Manual for Western Washington, issued by the Washington State Department of Ecology in August 2001 and updated in February 2005, as the set of stormwater management standards for all new development and redevelopment in Jefferson County. The 2001/2005 Manual replaces the previously utilized 1992 Ecology stormwater manual. Section 6.7 of the Unified Development Code (UDC) describes Jefferson County's stormwater management standards and regulations. Visit the UDC page for line-in/line-out language and UDC replacement pages for Section 6.7. On February 10, 2003, the Board of County Commissioners (BOCC) adopted an ordinance delaying implementation of the 2001 Ecology Stormwater Management Manual for Western Washington (2001 Manual) until July 1, 2003. The delayed implementation was in order to establish a transition period for County staff and the public to prepare more thoroughly for the switch from the 1992 Manual to the 2001 Manual.
The 2001/2005 State Department of Ecology Stormwater Management Manual for Western Washington can be accessed from Ecology's stormwater information website. Under the "Technical Information" heading, you will find a link to the Manual. Hard copy and CD-ROM versions of the Manual can be ordered from Ecology. As a companion to the Stormwater Manual, the January 2005 Low Impact Development Technical Guidance Manual for Puget Sound is available from the Puget Sound Action Team.
Stormwater Management Training/Education The County hopes to be able to help organize training and education opportunities for members of the development community (contractors, designers, engineers, septic installers, etc.) in the coming months. Element #12 (Manage the Project) of Minimum Requirement #2, which covers the Stormwater Pollution Prevention Plan required for most projects, mandates that a Certified Professional in Erosion and Sediment Control be on-site or on-call at all times during the construction period. Certification may be through the Construction Site Erosion and Sediment Control Certification Program offered by the Washington Department of Transportation/Associated General Contractors of Washington--Education Foundation, or any equivalent local or national certification and/or training program (Manual, p.3-15). Visit these sites for more information on the certification training: Additionally, the Washington Organic Recycling Council is coordinating workshops on soil amendment entitled, "New Strategies for Stormwater Management: Implementing the Post-Construction Soil Quality and Depth BMPs." The University of Washington put on a short course April 9 and 10, 2003 on "How to Improve Stormwater Management Using Low Impact Development (LID) Principles and Practices." This new course is oriented toward stormwater engineers, planners, and members of the development community who are interested in learning more about low impact development. Emphasis will be on site design and individual practices. There may be similar opportunities in the future. Check the Ecology stormwater management site periodically for training opportunities.
The Puget Sound Action Team has assumed a leadership role in promoting "low impact development" (LID) techniques, specifically in relation to stormwater management. Information related to LID can be found on the Action Team's "Low Impact Development" program page, including the following publications:
Jefferson County LID Evaluation The Puget Sound Action Team selected Jefferson County in 2005 as part of a set of a dozen local governments to receive consultant assistance to examine development regulations to optimize opportunities to employ LID stormwater management techniques. Following are links to PDF documents related to the evaluation:
For more information about stormwater management standards and regulations, contact DCD. For technical questions related to stormwater management requirements for land division, commercial, and industrial development proposals, contact the Department of Public Works. Additionally, the State
Department of Ecology has a site
dedicated to stormwater management with links to more
information and useful tools. For example, Ecology offers
guidance material for developing an NPDES-compliant Stormwater Pollution
Prevention Plan for industrial projects.
