State of Washington Department of Ecology <br />Agreement No: WQC-2022-EverPW-00085 <br />Project Title: Water Quality Treatment at 3rd Avenue SE <br />Recipient Name: City of Everett <br />contributing area was generally constructed prior to the advent of water quality treatment requirements and few flow <br />control or treatment measures are present. North Creek is core summer salmonid habitat and discharges to Lake <br />Washington. <br />The concept design will be taken from the RECIPIENT's Surface Water Comprehensive Plan (Plan). The Plan calls for <br />stormwater treatment using proprietary cartridge filter vaults to meet ECOLOGY -defined basic treatment standards. <br />The RECIPIENT will install TAPE approved devices to achieve at least pretreatment and basic treatment. During <br />design, the RECIPIENT will explore several locations along 3rd Avenue SE to determine if the project can achieve <br />enhanced treatment. <br />Overall Goal: <br />This project will help protect and restore water quality in Washington state by reducing stormwater impacts from <br />existing infrastructure and development. <br />Page 2 of 44 <br />Template Version 12/10/2020 <br />
