Meeting Date: 09/12/2017 By: Bruce Westby, Engineering/Public Works Information Title: Adopt Resolution #17-09-214 Approving Plans and Specifications and Authorizing Advertisements for Bids for Improvement Project #17-10, Puma Street Utility Extensions Purpose/Background: Purpose: The purpose of this case is to consider adopting Resolution #17-09-214 approving Plans and Specifications and authorizing Advertisements for Bids for Improvement Project #17-10, Puma Street Utility Extensions. Background: The proposed Puma Street utility extensions are needed to support the current Riverstone residential development, as well as future development east of Puma Street and a smaller area west of the Riverstone development. This area of the City is within the MUSA requiring service by City sewer and water. Figure 1 (attached) shows the trunk utilities extension project location and scope. The City recently extended trunk watermain and sanitary sewer along the west end of Bunker Lake Boulevard to Puma Street to serve the Riverstone development, as well as PSD's Bunker Lake Industrial Park. The trunk watermain under Bunker Lake Boulevard is 16-inch ductile iron pipe (DIP), and the trunk sanitary sewer is 18-inch polyvinyl chloride (PVC) pipe. Puma Street was constructed with a temporary pavement section consisting of roughly 2 inches of bituminous pavement over a few inches of aggregate base. Permanent street and trunk utility improvements were intended to be constructed along Puma Street as adjacent properties developed. The temporary street section is proposed to be improved in the spring/summer of 2018 after utilities are extended later this fall. A portion of the south end of the Riverstone development will be served by the utilities previously extended along Bunker Lake Boulevard. Phase IA in the attached Future Business Park Proposal addresses this. Public utilities must be extended north along Puma Street to serve the remaining homes in the Riverstone development. In addition, the Puma Street utility extensions will serve properties east of Puma Street, as well as the Northfork property just west of the Riverstone development and south of Alpine Drive. Phase 1B in the attached Future Business Park Proposal addresses this work. An Assessment Agreement was recently executed between the City and two adjacent property owners. This will allow the City to recover 40% of the project costs to extend utilities along Puma Street. The remaining 60% of the costs will be paid from City sewer and water utility enterprise funds. City costs will be recovered over time through trunk utility and connection fees. Capstone Homes is currently constructing the Riverstone development. If plans and specifications are approved and
