City of Everett • 2024 Comprehensive Sewer Plan • October 2025 <br />Executive Summary • ES-1 <br />Executive Summary <br />Introduction <br />The State of Washington adopted the Growth Management Act (GMA) with the intent of creating a <br />consistent and unified growth planning process. The GMA requires that the City of Everett (City) create and <br />enact a Comprehensive Plan to provide a 20-year blueprint for local policy, planning and capital facility <br />investment. A Comprehensive Plan is used as a guide for local governments through the establishment of <br />vision statements, goals, objectives, policies, and implementing actions. The City maintains a <br />Comprehensive Sewer Plan (CSP) that constitutes the sewer capital facilities element of Comprehensive <br />Plan in accordance with state law. The last CSP was completed in 2014 and covered a timeframe of 24 <br />years. <br />This City of Everett 2024 Comprehensive Sewer Plan (2024 Plan) provides a road map for the City service <br />area’s long-term wastewater infrastructure needs, based on 10-year and 20-year planning horizons <br />covering the years 2024 to 2043. Planning the wastewater infrastructure needs of a dynamic and fast- <br />growing region is challenging. Expanding populations in the City will require sewer service and the City will <br />be responsible for appropriately collecting, conveying, and treating increasing wastewater flows. <br />Infrastructure design and implementation will be strategically planned to maximize financial resources. <br />Federal, State, and Local regulations contribute to a need to be on the cutting edge of emerging <br />technologies and require the utility to continually think ahead. Planning at this level involves weighing a <br />complicated array of interconnected—and often conflicting—factors and variables. The Plan provides a <br />framework for the City to continue to manage growth within the context of a citywide wastewater service <br />network and achieve the overall goal of providing sewer service to protect public health and the quality of <br />the City’s water resources. <br />The City has focused recent planning efforts and capital improvement plans on the combined sewer system. <br />This is driven by regulatory requirements related to combined sewer overflows. While the 2024 Plan also <br />evaluated the combined sewer system, more emphasis was put on evaluating the separated sewer system. <br />This included installation of flow meters throughout the system and calibration of a hydraulic model. <br />Previous planning efforts related to the sewer collection system are briefly described below: <br />2020 Comprehensive Plan Amendment reflects the Vision 2040 Regional Growth Strategy adopted <br />in 2008. Growth rates and utilities planning inform system analysis and Capital Improvement Plan <br />(CIP) project development for the 2024 Plan. <br />2014 CSP provided a plan to guide improvements of the City’s sewer system. The 2024 Plan carries <br />forward information contained in this prior plan such as level-of-service goals and planning criteria. <br />2021 Water Pollution Control Facility (WPCF) Facilities Plan (2021 Facilities Plan) developed by <br />Stantec Inc. assessed the WPCF and recommended improvements through the year 2040. The <br />content in this document will be summarized and the updates at WPCF since 2021 Facilities Plan <br />developed are provided in Chapter 8. <br />2021 Port Gardner Storage Facility (PGSF) General Sewer Plan (GSP) recommended using the PGSF <br />(formerly Kimberley Clark industrial wastewater treatment plant purchased by the City in 2019) to <br />provide temporary storage and bring four combined sewer overflow (CSO) outfalls, Puget Sound
