throughout construction. In March 2017, Bolton Menk updated the Future Business Park report to include estimated costs for extending trunk utilities to Puma Street. A copy of the updated report is attached. Per their report, costs to extend the 16-inch trunk watermain line 1,400 feet to Puma Street, including fire hydrants and service stubs to abutting properties to the north and south, were estimated at $154,000. Costs to extend the 18-inch trunk sanitary sewer line 1,400 feet to Puma Street, including manholes and service stubs to abutting properties to the north and south, were estimated at $179,000. These costs include 30% contingency and indirect costs. All costs to extend utilities are proposed to be paid with City sewer and water funds. The developer's share of these costs will be recovered through their trunk utility fees at the time of development. The City is currently working with Capstone Homes to develop an assessment agreement to allow the City to construct the remaining public infrastructure needed to support their development, including trunk utilities, streets, and sidewalks/trails along Bunker Lake Boulevard and Puma Street. The assessment agreement will allow the City to assess the developer for a pro-rata share of construction costs. Staff anticipates being able to present the assessment agreement to the City Council for consideration of approval on July 25th. Capstone Homes proposes to begin construction of the Riverstone development this summer, with development of the lots on the south end occurring first. To issue Certificates of Occupancy, homes must be served by City sewer and water. This requires the existing trunk utilities along Bunker Lake Boulevard to be extended through Puma Street. By completing this work as a City improvement project in advance of the assessment agreement improvements, Capstone Homes will be able to connect more homes to City sewer and water in the fall of 2017 due to the time that will be saved by extending trunk utilities to Puma Street in advance of the assessment agreement improvements. Per City Council direction, Staff prepared plans and specifications to extend trunk sanitary sewer and watermain along Bunker Lake Boulevard through its intersection with Puma Street this summer to support the current Riverstone development proposal, as well as all future development proposals within the Future Business Park area. Attached is a copy of the draft plans for the proposed improvements. The City Council accepted plans and specifications and authorized advertisements for bids on May 23rd.
