Riverstone residential development, west of Puma Street. Currently there are no plans to begin construction of the <br />Alpha/AKM Farms development, east of Puma Street. <br />Streets and Trails <br />Approximately 1,000 feet of Puma Street and the adjacent regional trail south of Alpine Drive must be realigned <br />and reconstructed to replace the existing temporary street section with a permanent street section including <br />bituminous pavement, concrete curb and gutter, storm sewer, and associated appurtenant improvements. Municipal <br />trunk utilities must also be extended to support continued development. <br />The proposed street, storm sewer and trail improvements meet all applicable State Aid standards including curb and <br />gutter design, pavement structural capacity, horizontal and vertical curves, lane and shoulder widths, and clear <br />zones. Puma Street will meet a 9-ton all-weather pavement design following construction. The required State Aid <br />approvals have been received allowing for award of a construction Contract. <br />Trunk Watennain <br />Trunk 16-inch DIP watermain is proposed to be extended to the north to serve the Riverstone 4th Addition and the <br />Alpha/AKM Farms development with water, and to provide a looped watermain system along Puma Street and <br />Alpine Drive to more reliably serve properties in the immediate area, provide better fire flows, and provide better <br />water quality by removing a dead end. Alpine Drive is scheduled to be reconstructed in 2025 per the City's current <br />Capital Improvement Program (CIP), at which time trunk wateiinain will be extended along Alpine Drive to <br />connect the existing trunk watermain running parallel to Armstrong Boulevard to the watermain installed under <br />Puma Street with this project. <br />Trunk Sanitary Sewer <br />Trunk 8-inch PVC sanitary sewer is proposed to be extended to the north to serve the Riverstone 4th Addition and <br />the Alpha/AKM Farms development with sanitary sewer. The sewer is not designed to serve properties north of <br />Alpine Drive with municipal sewer. Those properties can be served, if needed, from a future trunk sewer line along <br />Armstrong Boulevard. <br />Storm Sewer <br />The proposed Puma Street improvements include construction of a permanent urban street section with concrete <br />curb and gutter and storm sewer improvements, including connections to an adjacent stormwater pond in the <br />Riverstone development. <br />Notification: <br />Advertisements for bids were published in both the City's official newspaper, the Anoka Union Herald, and in <br />Finance and Commerce, on Friday, May 29th, and Friday, June 5th. <br />Observations/Alternatives: <br />Observations: <br />Bid Addendum #1 was issued to allow the northerly sanitary sewer manhole to be lowered approximately one -foot <br />to ensure adequate depth will exist to serve the Alpha/AKM Farms development with sanitary sewer upon <br />development. <br />Since this segment of Puma Street is being realigned it must be closed for a period of time. However, all properties <br />will remain accessible from the south and detour signing will be provided. Access for emergency services will be <br />maintained throughout construction. <br />Project schedule <br />June 23 — Accept Bids / Award Contract <br />Early July — Begin construction <br />September 25 — Substantial completion (fully open to traffic) <br />October 16 — Final completion <br />
