advertisements for bids are authorized by Council, the Puma Street trunk utility extensions should be operational by the end of December. This will just meet the developers desired utility service schedule allowing Certificates of Occupancy to be issued for homes in the central area of the Riverstone development. An exception to this is that the lift station pumps may not be operational until next spring, which means the wet well would need to be manually pumped periodically until the pumps are operational. The Public Works Committee recommended Council approval of ordering plans and specifications once financial securities were in place to pay for the work. Since the Assessment Agreement has been executed, financial securities are available to pay for a portion of the engineering and construction costs. Notification: Notifications are not required for this case. Bids will be advertised twice, once on Friday, September 15th, and again on Friday, September 22nd. Observations/Alternatives: Observations: Final plans and specifications for this project will be available at the Council meeting. At the time this report was prepared, Bolton Menk was finalizing plans and specifications, with the exception of the lift station controls. These plans, which are being completed by a subconsultant, will be complete soon and will be incorporated into the plans by addendum. Puma Street is proposed to be restored using temporary surfacing composed of a minimum of 4" of the reclaimed pavement material. This temporary surfacing will only be in place over the winter, and Puma Street currently has low traffic volumes and is proposed to be reconstructed next spring/ summer so no issues are anticipated with this low-cost approach. The future permanent street improvements will require future Council approval. Alternatives: Alternative #1 — Motion to recommend adoption of Resolution #17-09-214 approving Plans and Specifications and authorizing Advertisements for Bids for Improvement Project #17-10, Puma Street Utility Extensions. Alternative #2 — Motion denying adoption of Resolution #17-09-214 at this time. Funding Source: Bolton & Menk prepared plans and specifications. Attached is a copy of their work proposal dated June 20, 2017. Their engineering fees were proposed at $104,780. In March of 2017, Bolton Menk updated the Future Business Park report to include estimated costs for extending trunk utilities along Puma Street. These are called out as Phase 1B improvements. A copy of the updated report is attached for reference. The report identifies estimated costs to extend trunk watermain along Phase 1B of Puma Street at $182,000, and to extend trunk sanitary sewer at $545,000. These costs total $727,000 and include 30% contingency and indirect costs. However, this cost does not include costs to restore the street surface in a temporary manner over winter months. Staff estimates these costs at roughly $50,000. An updated project cost estimate based on final plans and specifications will be presented during the Council meeting. City staff proposes to administer the project and to inspect construction. All City project costs (costs not covered by other parties through the Assessment Agreement) are proposed to be paid through City sewer and water utility funds. Recommendation: Staff recommends alternative # 1 to support current and future development opportunities in this area of the City. Action:
