to construct a new lift station and force main to replace the existing station. A force main will <br /> convey flow to a point further east along the shoreline interceptor, thus allowing the City the <br /> option of abandoning a significant portion of the interceptor. The force main is anticipated to <br /> be approximately 2,700 feet long. The flow from the Port of Everett facility would need to be <br /> rerouted to discharge to the new lift station. The first phase of the project is to confirm the <br /> capacity and sizing of the primary elements of the proposed improvements and to identify and <br /> evaluate potential sites for the lift station. <br /> The City has preliminarily identified three alternative sites, as follows: <br /> A. Immediately adjacent to existing station, but out of the way of the bridge project <br /> B. Across Shore Ave. in the park existing parking area <br /> C. On Shore Ave., on the north side of the park property <br /> As addressed in the Scope of Work, one or two additional sites may be considered, and all <br /> identified alternatives will be initially screened to develop a shortlist of up to three sites, for <br /> more detailed evaluation and comparison. The City desires a submersible pump type of station <br /> with valve vault and standby generator and continued use of calcium nitrate for odor <br /> management. The configuration of station, power and control equipment, standby power <br /> equipment and Bioxide® storage varies with each siting option, particularly to maintain public <br /> access to and use of the park in options B and C. It is anticipated that the station power <br /> equipment will include variable frequency drives (VFDs)for pump motor power supply. <br /> Scope of Work: <br /> The proposed scope of services for the Siting Evaluation and Pre-Design phase of engineering <br /> services is presented below. CHS will be supported by Bob Casne, P.E. of RJC Engineering, <br /> PLLC, for the power and standby power elements of this scope of work. <br /> 1. Project Management <br /> 1.1. Project Planning <br /> 1.2. Monitoring and Control <br /> 1.3. Project Closeout <br /> 2. Resources and Documentation <br /> 2.1.Review: review City preliminary planning and outline of project including force main <br /> alignment and profile and use of package lift station equipment. Review city-provided <br /> resources including GIS data for existing utilities and prior geotechnical analysis. <br /> 2.2.Site Visit: complete site visit with City personnel to observe existing station, structure, <br /> access, Bioxide® equipment and tank, existing power facilities, potential station <br /> locations and force main alignment and point of discharge. <br /> 2.3.Site Survey: complete topographical survey of alternative sites and force main <br /> alignment. Survey data will be integrated with data provided electronically by the City <br /> for property and right of way boundaries and prior topographical surveys in the area <br /> completed by or for the City, for recent private infrastructure improvements and/or for <br /> the bridge replacement project. <br /> 2.4.Planning Maps: <br /> 2.4.1. Prepare planning-level plan and profile sheets along Shore Ave., based on GIS <br /> data and site visit observations, to document existing conditions for planning and <br /> evaluation purposes. <br /> CHS Engineers, LLC Page 2 of 5 <br />
