Legion Golf Course Stormwater Detention Project City of Everett Work Order#UP3620 EXHIBIT C-1 Scope of Work Final Design,Bidding and Construction Support Murray, Smith&Associates, Inc. (MSA) has developed the following scope of work and fee estimate for final design, bidding and construction support services for the Legion Golf Course Stormwater Detention Project, City of Everett Project#UP3620. The scope and fee have been developed based on our discussions with City staff,the preliminary design and our project understanding and proposed approach to the work. The upstream stormwater collection network tributary to this project is divided into two phases: Phase 1 —N. Wetmore Ave Stormwater Separation Project and Phase 2—Alverson Blvd Stormwater Separation Project. It is intended that Phase 1 will be constructed together with this project. Background The need for this project is based on the City's 2014 Comprehensive Sewer Plan(CSP) Update Capital Improvement Plan, in which it is recommended that the City construct a separate storm water network to effectively mitigate flooding and backup issues in the North Everett Combined Sewer System. The project area is located in the northwest area of north Everett, specifically between 10th streets and 3rd Street, Alverson Boulevard and Wetmore/Rockefeller Avenues, and due west of the Legion Memorial Golf Course and Everett Community College Campus (EvCC). This project together with the N. Wetmore and Alverson Stormwater Separation projects will address the following sewer and storm drainage issues: • Reduce basement flooding on Alverson, Grand, Rucker, Hoyt, Colby and Wetmore Avenues between 4th and 10th St., • Reduce sewer backup/storm water flooding problems at Rainier hall at EvCC • Improve "level of service"for sewer collection system in overall general area • Separate storm water drainage and detention facilities • Reduce wet weather flow rate in C-Basin trunk sewer • Reduce wet weather flows to siphon headworks and CSO overflows at SR02 and SRO3. The City and HDR(author of the CSP) agree that sanitary sewer upsizing/replacement will not reliably eliminate the basement flooding problem and that a separate stormwater network will be more effective. In addition,the City has engaged the City Parks department manager and the operations managers of Legion Golf Course (Parks) and has discussed the concept of utilizing water features within the golf course for stormwater detention and increase the quality of play at the course.
