EXHIBIT A-1 GEOTECHNICAL ENGINEERING SCOPE OF WORK CITY OF EVERETT Jackson Park Area Stormwater Separation Project WO# UP3703 Introduction and Background The City plans to design and construct stormwater treatment system on vacant City-owned land together with miscellaneous drainage collection improvements in the associated catchment area. See attached exhibit map. Everett Parks is a partner in this project related to drainage management needs of future improvements at Jackson Park in this project. The proposed Stormwater pipe network will generally consist of 12" diameter pipe, with inlets and catch basins at various locations. Survey base mapping is needed for design and restoration. Scope of Services The purpose of geotechnical services is to evaluate subsurface soil and groundwater conditions as a basis for providing geotechnical engineering recommendations for design and construction of the proposed storm water pipes and structures. More specifically: • Stormwater conveyance pipelines, inlets and catch basins generally less than 10 feet deep, • Bore and Jack pipeline crossing at East Marine View Drive including jacking and receiving pits, • Stormwater treatment units generally comprised of below-ground precast concrete vaults less than 10 feet deep. Geotechnical consultant's proposed scope of services will include, and not be limited to, the following tasks: 1. Review Previous Geologic and Subsurface Information a. Review subsurface information, existing construction data, and other available geotechnical reports in the vicinity regarding subsurface soil and groundwater conditions. An attached map shows locations of several previous borings generally in the north part of the project area. 2. Plan the Exploration Program and Obtain Permits a. Complete a site visit to locate the proposed borings, call for underground utility locates, plan the traffic control operations, and develop right-of-way permit applications, as required. i. Provide recommendation to number and locations of borings. Provide a minimum of one boring per block. Include rationale in Geotechnical consultant's choice in the number and locations of borings if different from the one boring per block minimum. ii. Locate all borings within paved surface so as to measure and record paved surface types and thickness. b. Submit permit applications, traffic control plans, and boring exploration plans to City of Everett for review and approval. i. Geotechnical Consultant is responsible for notifying public of no parking if borings are located within street parking areas. City forces will post the no parking signage provided Consultant gives City times and dates and minimum of 48 hours' notice. Consultant may not begin boring activities until a minimum of 48 hours after City posts the signage. 3. Field Explorations and Laboratory Testing 1
