Edgewater Park Renovation <br />PSA Amendment No. 1 <br />Amendment to Project Service Description: <br />MxM Landscape Architecture (MxM) to provide Architecture & Engineering services for the <br />renovation of Edgewater Park, located at 3802 Shore Ave., Everett, WA. Additional services are <br />required to revise plans and specifications as needed per the results of geotechnical site <br />investigation and to undertake value engineering with the goal of reducing project construction <br />costs. <br />Project services will include: <br />• Value engineering exercise including one meeting with City and up to 6 hours of plan <br />revision by the MxM <br />• Updated stormwater management approach <br />• Updated Drainage Report <br />• Updated drainage plans, details, and specifications <br />• Production of final construction documents to reflect City review comments <br />• Phase 1 bid and construction support services <br />• Production of a reconciled Phase 2 construction set, taking into account site conditions <br />following the construction of Phase 1 and the status of the Edgewater Bridge Replacement <br />and Lift Station #15 projects. <br />• Phase 2 bid and construction support services <br />• Record drawings <br />PSA Scope History: <br />Original PSA scope assumed no change to stormwater management on site. Previously completed <br />geotechnical analysis did not include infiltration study. Project was found to require infiltration <br />analysis, drainage report, and long form SWPPP, necessitating change in scope and use of PSA <br />contingency, approved by project manager in 2023. <br />Additional geotechnical study found that infiltration is infeasible on the eastern portion of the site <br />most distal to steep slopes. City of Everett Surface Water Management examined the proposed <br />infiltration facility on the western portion of the site and determined that further geotechnical <br />analysis was needed. Areas of concern were 1) Destabilizing effects of groundwater flows on <br />nearby slopes and 2) Need to monitor facility after construction to confirm performance, given the <br />high potential for soil compaction during Edgewater Bridge construction activities currently taking <br />place. <br />Completing this analysis to support infiltration approach to stormwater is cost and schedule <br />prohibitive. City of Everett project manager determined that directing the A&E consultants to <br />change stormwater management approach to detention was the best course of action to keep the <br />project moving forward. <br />
