SUBAWARD AGREEMENT BETWEEN SNOHOMISH COUNTY AND <br />CITY OF EVERETT FOR ROUTE AND COST BENEFIT ANALYSIS TO Page 11 of 17 <br />RELOCATE WATER TRANSMISSION LINE NO. 5 <br /> <br /> <br />TASK 2:WATER TRANSMISSION LINE #5ROUTE ANALYSIS STUDY <br />The City will hire a consultant to conduct an analysis of a new route or routes to relocate the <br />City's water transmission line #5 (TL #5) out of the Chinook Marsh habitat restoration footprint. <br />This work is necessary to determine the best route for TL #5 and ensure seismic resilience of this <br />major drinking water transmission line, ease of access for maintenance and operation, and to <br />minimize conflicts with existing and planned utilities. <br />The consultant hired by the City will: <br /> Develop alternative routes for the relocated transmission line. <br /> Conduct workshops with the County and City to review possible routes and the <br />restoration projects planned in the area. <br /> Develop weighted evaluation criteria for evaluating the alternative routes. Criteria may <br />include but are not limited to engineering considerations, property ownership, operations <br />and maintenance, project cost, and environmental impacts. <br /> Conduct an initial screening of possible routes and identify any with fatal flaws based on <br />the developed evaluation criteria and create a short list of approximately three to five <br />alternative routes. <br /> Perform site reconnaissance, including physical inspection, of the short list alternative <br />routes to identify additional considerations. <br /> Evaluate the short list alternative routes against the evaluation criteria. Prepare a Route <br />Study Memorandum documenting an analysis of the alternative routes and identify a <br />preferred alternative. <br /> <br />Deliverable Deliverable Description Due <br />2.1 TL #5 Route Study Memorandum 12 Months after Notice <br />to Proceed <br />TASK 3:WATER TRANSMISSION LINE #5BENEFIT-COST ANALYSIS <br />The City will hire a consultant to complete a Benefit-Cost Analysis (BCA) for the relocation of <br />the City's water transmission line #5 (TL #5) out of the Chinook Marsh habitat restoration <br />footprint. This work is necessary to determine the Benefit-Cost Ratio for the project, which is <br />required for future grant applications to receive federal funding for a project to relocate the <br />waterline. <br />The consultant hired by the City will: <br />Prepare a BCA in accordance with the procedures defined under FEMA grant programs <br />and utilizing the FEMA BCA Toolkit. <br />BCA will consider flood/inundation risk and seismic susceptibility.
