Puma Street, and Riverstone 4th Addition by Capstone Homes on the west side. Exhibits showing the location and scope of each development are attached to this case. This spring Capstone Homes began development of Riverstone 4th Addition located on the north half of the Riverstone residential development, west of Puma Street. Currently there are no plans to begin construction of the Alpha/AKM Farms development, east of Puma Street. Streets and Trails Approximately 1,000 feet of Puma Street and the adjacent regional trail south of Alpine Drive were realigned and reconstructed to replace the existing temporary street section with a permanent street section including bituminous pavement, concrete curb and gutter, storm sewer, and associated appurtenant improvements. All street, storm sewer and trail improvements meet all applicable State Aid standards including curb and gutter design, pavement structural capacity, horizontal and vertical curves, lane and shoulder widths, and clear zones. Puma Street meets a 9-ton all-weather pavement design. Trunk Watermain Trunk 16-inch ductile iron pipe watermain was extended north along Puma Street to Alpine Drive to serve the Riverstone 4th Addition and the Alpha/AKM Farms development with water, and to ultimately provide a looped watermain system along Puma Street and Alpine Drive. Looped watermain will more reliably serve properties in the area, provide better fire flows, and provide better water quality by removing a dead end. Alpine Drive is scheduled to be reconstructed in 2025 per the City's current Capital Improvement Program (CIP). At that time, trunk watermain will be extended along Alpine Drive to connect the existing trunk watermain running parallel to Armstrong Boulevard to the watermain installed under Puma Street with this project. Trunk Sanitary Sewer Trunk 8-inch poly -vinyl chloride sanitary sewer was extended north along Puma Street to serve the Riverstone 4th Addition and the Alpha/AKM Farms development with sanitary sewer. The sewer is not designed to serve properties north of Alpine Drive with municipal sewer. Those properties can be served in the future, if needed, from a proposed trunk sewer line along Armstrong Boulevard. Storm Sewer The Puma Street improvements included construction of a permanent urban street section with concrete curb and gutter and storm sewer improvements, including connections to an adjacent stormwater pond in the Riverstone development. Public Comment AKM Farms/Paxmar has stated that they are not supportive of being assessed at this time via emails. All public comments received prior to the Assessment Hearing will be presented to the City Council before the Assessment Hearing is opened. Notification: Following Council approval, an Assessment Hearing Notice will be published in the City's official newspaper on Friday, September 25, 2020. Assessment Hearing Notices will also be mailed to all benefiting property owners as required by State Statute. Anoka County requires that assessments be certified to the County Auditor by November 16, 2020 for collection on next year's (2021) taxes. November 16, 2020 will therefore be the last day that assessed property owners can prepay their special assessments without paying interest. Conducting the Assessment Hearing at the regular City Council meeting on October 13, 2020, will therefore allow more than 30 days for mailing the required assessment notices to property owners.
