Deliverables: <br /> 1. Submittal reviews, clarifications as requested by the City. <br /> Task 14—Unanticipated Labor or Expenses (Modeling Support) <br /> Murraysmith developed and delivered a detailed InfoSWMM model representing the NWSS <br /> conveyance system as part of the preliminary design(30 percent) effort in July 2016. The City <br /> assumed control of the NWSS Project, currently divided into two project areas: the North <br /> Wetmore Stormwater Separation project and the Alverson Boulevard Stormwater Separation <br /> project and anticipates completing the projects internally. Murraysmith revised the InfoSWMM <br /> model to match the North Wetmore Stormwater Separation project 75 percent design plans in <br /> September 2017 to confirm conveyance capacity of the proposed improvements. The City has <br /> now requested that Murraysmith update the InfoSWMM design per the City's 50 percent design <br /> plans for the Alverson Boulevard Stormwater Separation project. The NWSS modeling support <br /> includes the following services requested by the City: <br /> • Revision of the InfoSWMM model to match the Alverson Boulevard Stormwater <br /> Separation project 50 percent design plan and profile drawings. Confirmation of the <br /> conveyance capacity for the 25- and 100-year, 24-hour design storm events and <br /> recommendations for system modifications per model review. <br /> Assumptions: <br /> 1. InfoSWMM model updates will not be required beyond the 50 percent design for <br /> the Alverson Boulevard Stormwater Separation project. <br /> Task Deliverables: <br /> 1. Correspondence with the City, via email, regarding modeling conditions and results. <br /> 2. Updated InfoSWMM model input and results files. <br /> City of Everett Murraysmith Legion Golf Stormwater <br /> October 2018 Page 2 of 2 <br />
