Alternate Bid Watermain and sanitary sewer extend from the west end of Rivlyn Avenue to Riverdale Drive, generally under green space and a shared drive. As an alternate bid, the watermain is proposed to be replaced in the same manner as the watermain under Rivlyn Avenue and Tungsten Street. The private shared driveway is proposed to be replaced to match existing materials, a combination of gravel and bituminous. The utilities are under an existing drainage & utility easement between Rivlyn Avenue and Riverdale Drive, however, during design Bolton & Menk indicated additional temporary construction easement will be necessary to actually perform the construction. In total, 5,364 square feet of easement spread across four properties would be required as shown in the attached temporary easement exhibit. Staff mailed letters to the impacted properties on February 12, 2025. To date, staff have been contacted by 3 of the 4 property owners, only one of whom is agreeable to the temporary easements without further discussions necessary. Because the alternate bid is not under Rivlyn Avenue itself, the work could be completed under a future project without delaying the delivery of this project. If this is the case staff recommend adding a future watermain replacement project to the Capital Improvement Plan.
