Meeting Date: 02/12/2019 By: Bruce Westby, Engineering/Public Works Information Title: Adopt Resolution # 19-049 Accepting Bids and Awarding Contract for Riverdale Drive Trunk Utility Improvements, Improvement Project #18-14 Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #19-049 accepting bids and awarding a construction contract for Riverdale Drive Trunk Utility Improvements, Improvement Project #18-14. Background: This project proposes to extend 18-inch polyvinylchloride (PVC) trunk sanitary sewer and 12-inch ductile iron pipe (DIP) trunk watermain from existing utility stubs in the southwest corner of old Armstrong Boulevard and Riverdale Drive approximately 2,600 feet west along the south side of Riverdale Drive to roughly the intersection of Llama Street and Riverdale Drive. Attached is a copy of the construction plans as bid. The proposed improvements will initially serve the new Lazydays RV maintenance facility in the southeast quadrant of Riverdale Drive and Llama Street. A condition of Plat approval was that the maintenance facility connect to City sewer and water since it is located within the City's Metropolitan Urban Service Area (MUSA). The maintenance facility is under construction and includes 20 service bays, a customer waiting area, parts warehouse, receiving dock, and office space. Approximately 30 staff will work in the maintenance facility, including service managers and technicians, warehouse staff, and customer service representatives. Area is reserved for future expansion. Civil Site Group, Lazydays RV's engineer, developed the plans used to bid the trunk utility improvements. Lazydays RV initially proposed to construct the trunk watermain and sanitary sewer with their development, with the City reimbursing them a pro-rata share of the costs. Initially, trunk watermain was proposed to be constructed to the edge of their site from the existing stub at Armstrong Boulevard, and sanitary sewer was proposed as a trunk gravity system from the existing stub at Armstrong Boulevard to roughly halfway to their site, with the remaining sewer to be installed as forcemain with a lift station at their facility. Concurrently, Staff was working with Bolton & Menk on a West Riverdale Drive roadway and utility extension analysis. This analysis ultimately revealed that extending 18" trunk sanitary sewer west of Llama Street was feasible and would most cost-effectively serve all development south of Highway 10 and west of Armstrong Boulevard with sanitary sewer. Staff then decided that trunk sanitary sewer and watermain would best be constructed as a City improvement project, and that Lazydays RV could then pay their portion of the costs through trunk fees, as is typically the case when utilities are available to serve a site. City Staff immediately started working with Civil Site Group to complete
