• Grading for landings and street improvements. Grading will include both spot elevations and contours necessary for construction. KPFF will provide wall elevation profiles and top and bottom of wall elevations on plans. • Utility relocations necessary for the construction of the proposed improvements. KPFF will provide water service extensions necessary for irrigation. • Route 36-inch Public Storm Sewer from connection with Sewer "M" Project in Grand Avenue to approximately 50-feet beyond west bridge landing, see Exhibit H for project limits. • Route 30-inch CSO pipe extension from connection with Sewer "M" Project in Grand Avenue to approximately 50-feet beyond west bridge landing; see Exhibit H for project limits. • Route a force main (dry) together with storm and combined sewer pipes, except this force main will be capped at 16th and Grand for future extension with the Sewer "M" Project. This force main will be extended north to 50 feet within this Phase 1, and extended further north to the lift station under Phase 2. • Under the Utility/Pedestrian Bridge, include allocated spaces for a water main pipe for future installation by City of Everett under a separate contract. • Traffic Control Plan for basis of bid in Grand Ave and W. Marine View Drive for the installation of the Utility/Pedestrian Bridge and utilities. • Undergrounding of overhead power distribution cables, beneath the Utility/Pedestrian Bridge in West Marine View Drive, will be accomplished in a separate infrastructure design of duct banks & vaults by KPFF with Snohomish County PUD guidance and meeting PUD design requirements. Once the infrastructure design has been approved by PUD, the infrastructure package will be sent out as an early bid package ahead of the Utility Bridge Package. PUD will be responsible to underground the conductors in the new infrastructure facilities. • Undergrounding of overhead communication cables, beneath the Utility/Pedestrian Bridge in West Marine View Drive. This task effort will include infrastructure design of duct banks and vaults coordinated with, and meeting the requirements of, the utility purveyors. The communication infrastructure will be part of the power undergrounding and will be bid at the same time. • Street improvement plans for Grand Avenue, and West Marine View Drive associated with the utility relocation and installations. The plans are comprehensive showing paving, drainage, utilities and horizontal control for elements designed by others, such as landscaping and street lighting. KPFF will provide standard MUTCD street signage and channelization for utility street restoration. Specifically, the street improvement scope is as follows: o Improvements to Grand Avenue are confined to the intersection with 16th Street. Specifically, providing curb, sidewalk and pavement replacement for installation of storm and utility systems and improvements to park areas disturbed with construction. No other improvements to Grand Avenue or 16th Street are anticipated, such as drainage, lighting, etc. o Improvements to West Marine View Drive are confined to repairs to existing street pavement, curb and sidewalk for installation of Storm and CSO systems, stubbed out force main, power and communication overhead to underground and potential relocation of existing street utilities to accommodate the new systems. No other improvements are anticipated, such as drainage, utilities, lighting, etc. In addition, KPFF will prepare cost estimates for civil design elements utilizing our cost database, City, County and WSDOT bid tabs and contacting contractors to verify major cost elements. The cost estimating effort includes a budget reconciliation effort with the City and design team prior to moving on to the next design phase.
