This project is anticipated to improve water quality in one of the City of Everett's 22 drainage basins in one of the City's 3 watersheds.The 3 watersheds are Port Gardner Bay/Possession Sound Watershed,the Snohomish Watershed and the Lake Washington Watershed. The RECIPIENT has completed a Receiving Water Condition Assessment,which is the first step in the SMAP,using existing information related to local receiving waters and contributing area conditions. Existing information includes the Surface Water Comprehensive Plan(SWCP)adopted in 2017. The SWCP is being updated in 2022. This SWCP is watershed—based and provides mapping and inventory of basins and receiving waters,basin characterizations,receiving water assessments,documentation and ranking of maintenance issues,and recommendations of projects to address flooding,water quality,and habitat for the highest ranked issues. The RECIPIENT has also completed an assessment of the MS4 influence on receiving water and the relative conditions and contributions to narrow the list of candidate basins for prioritization. This involved a more thorough evaluation of the potential water quality improvements needed in each basin,based on the water quality and BIBI data the City has collected over the past 30 years. From this evaluation, the RECIPIENT has created an inventory of the specific receiving waters and basins that are most likely to benefit from stormwater management planning. For this project,the RECIPIENT will submit the City of Everett SMAP Receiving Waters Assessment that documents these Receiving Water Condition Assessment tasks have been completed. From this inventory of candidate basins the RECIPIENT will complete the Receiving Water Prioritization with stakeholder and public input.After developing a prioritization and ranking process, the RECIPIENT will select a final high priority basin and sub-basin. Consideration of overburdened communities will be part of the decision process for selecting receiving waters and basins. The RECIPIENT will develop a matrix to consider costs,impact on different communities,predicted pollutant reductions,benefits to receiving waters,and other benefits in selecting the high priority sub-basin. The RECIPIENT will maintain communication with stakeholders and create public outreach opportunities on the receiving water prioritization. Feedback from stakeholders and residents will inform the development of the SMAP. The RECIPIENT will prepare a SMAP,a set of stormwater management actions that focuses on at least one high priority basin or sub-basin. The SMAP will identify strategic stormwater facility retrofits, land management strategies,and implementation of stormwater management actions related to the RECIPIENT's municipal stormwater permit, such as public education and outreach,code changes,and enhanced maintenance. The RECIPIENT will evaluate implementation of identified alternatives for the selected high priority area based on feasibility, cost effectiveness,environmental benefits,and ability to provide multiple benefits. The RECIPIENT will submit a Stormwater Management Action Plan for the Phase II Municipal Stormwater Permit deadline and will use this to guide investments in the short-term(6-year)and long-term(20-year)timeframe. Overall Goal: This project will help protect and restore water quality in Washington state by reducing stormwater impacts from existing infrastructure and development. Template Version 12/10/2020
