Executive Summary
The Olympic View Water & Sewer District (District) is located in southwestern Snohomish County in the State of Washington and encompasses portions of the City of Edmonds, the Town of Woodway and unincorporated Snohomish County, including the communities of Esperance, Westgate, and Firdale Village.
Deer Creek, Willow Creek, Chase Lake and Chase Lake Pond, located within the District, are considered critical habitat for aquatic life and recreational use. Currently, Deer Creek is the District’s surface water source. The 228th Street SW Well Field is the District’s new aquifer water source and consists of two wells; one well was dug in 2014, and a second well was dug in 2016. Both wells are scheduled to begin treatment and use in 2019.
The purpose of this Watershed Protection Plan is to develop and document a program for protecting, maintaining, and improving the quality and quantity of the District’s drinking water sources.
The District’s current Watershed Protection Plan was completed and approved by the Washington Department of Health (DOH) in 2002 and is on file at the District. This update to the District’s watershed plan is expected to supersede the 2002 plan in 2019 and is necessary due to adopted changes in land use and regulations requiring improved stormwater planning, and as part of the Deer Creek Evaluation and 228th Street SW Well projects.
The plan update also addresses the District’s new well field, which the District plans to bring online in 2020. The plan update discusses the new well field source and provides a more current assessment of the Deer Creek Spring source. Robinson Noble, Inc., provided a delineation of the District’s wellhead protection areas (WHPAs) for the 228th Street SW Well Field and updated the delineation and WHPAs for the Deer Creek source. The updated delineation shows that some potential contamination sources are located outside of the District’s service area. This protection plan update also determines how those areas will be addressed. The Robinson Noble report is provided in Appendix B. Information provided in the delineation report is summarized in this plan update.
