Northwest Stormwater Separation Project <br />City of Everett Work Order #UP3620 <br />Exhibit C - Scope of Work, Preliminary Design <br />Murray, Smith & Associates, Inc. (MSA) has developed the following scope of work and fee <br />estimate for engineering design, bidding and construction services for the Northwest <br />Stormwater Separation Project, City of Everett Project #UP3620. The scope and fee have <br />been developed based on our discussions with City staff and our project understanding and <br />proposed approach to the work. <br />Background <br />The need for this project is based on the City's 2014 Comprehensive Sewer Plan Update <br />Capital Improvement Plan, in which it is recommended that the City construct a separate <br />storm water network to effectively eliminate flooding and backup issues in the North Everett <br />Combined Sewer System. The project area is located in the northwest area of north Everett, <br />specifically between 10th streets and 3rd Street, Alverson Boulevard and <br />Wetmore/Rockefeller Avenues, and due west of the Legion Memorial Golf Course and <br />Everett Community College Campus (EvCC). This project will address the following sewer <br />and storm drainage issues: <br />• Eliminate basement flooding on Alverson, Grand, Rucker, Hoyt, Colby and Wetmore <br />Avenues between 4th and 10th St., <br />• Eliminate sewer backup/storm water flooding problems at Rainier hall at EvCC <br />• Improve "level of service" for sewer collection system in overall general area <br />• Separate storm water drainage and detention facilities <br />• Reduce wet weather flow rate in C -Basin trunk sewer <br />• Reduce wet weather flows to siphon headworks and CSO overflows at SR02 and <br />SR03. <br />The City and HIR (author of the CSP) agree that sanitary sewer upsizing/replacement will <br />not reliably eliminate the basement flooding problem and that a separate storinwater network <br />will be more effective. In addition, the City has engaged the City Parks department manager <br />and the operations managers of Legion Golf Course (Parks) and has discussed the <br />opportunity to retain stoimwater and reuse for irrigation purposes. Finally, the City would <br />also like to develop a public-private partnership with EvCC to evaluate and implement <br />improvements to solve flooding problems at Rainier Hall. <br />16 <br />_ <br />City 01 vZ1'�ti �,JUPs'�c�,.. y-TAIlH Sz ASSO'CUMTS. 11NIC.
