Scope of Work <br />continued <br />City of Everett 7 <br />Dorn Ave. Drainage Improvements Otak <br />TASK 5 DELIVERABLES <br />· Matrix table comparing options 2a and 2b outfall location and water quality configurations at <br />McGill including a figure. <br />· Matrix table and figure of Water Quality Treatment Option at Dorn Ave. <br />· Grant application level project writeup for each selected treatment option including: project <br />sketch, description, planning level estimate and figure showing catchment area treated. <br />TASK 5 ASSUMPTIONS <br />· Matrices include description, location, benefits, risks, and preliminary cost comparison for options. <br />Electronic submittal of matrices and figures (draft and final). <br />· Options for Dorn limited to five, options at McGill limited to five (ten total).. Some options will be <br />the same BMP at different locations or configurations. A different brand of the same type of BMP <br />at the same location/configuration is not a different option. <br />· Modeling and modeling documentation of the options is included in Task 4 – Drainage Analysis. <br />· Size of water quality treatment from the alternatives analysis will be used as a starting point: Dorn <br />12 EA – 8’x 24’ underground treatment units. McGill 2 EA – 8’x 20’ underground treatment units. <br /> <br />· The design standard will be Enhanced treatment with 6PPD-Q removal to the best available <br />knowledge at time of project. <br /> <br />6. Utility Coordination <br />6.1 Franchise Utility Coordination <br />Along Evergreen Way, Holly Avenue, Dorn Avenue, and McGill Avenue there will be potential conflicts <br />with water and sewer service lines as well as power, gas, and communication lines. In this task, Otak will <br />coordinate with and explore opportunities to design around existing utilities, but we do not recommend <br />compromising the quality and safety of the City’s improvements simply to avoid conflicts. It is possible that <br />various relocation efforts will be necessary. If this is the case, any private utility relocation design would <br />be completed by the utility companies. <br />Otak’s utility coordination in this task are as follows: <br />1. Obtain/Review Utility As-Built Records <br />Otak will contact applicable franchise utility companies (power, gas, and telecommunications) to <br />request record drawings for the project to verify locations of existing facilities and conflicts. <br />2. Coordinate with Everett <br />Otak will coordinate with City of Everett for the water and sewer utilities owned and operated by <br />the City. Up to 2 meetings will be held with the City water and sewer group. <br />3. Coordination with Utility Companies
