remainder of the sidewalk construction are estimated at approximately $40,000. The retaining wall work could also require modifications (insulating or relaying) to the watermain running from Noel Drive to the Water Tower and those costs are unknown at this time. Requested Council Input We are recommending that a Contractor be utilized to add a new valve to the Water Tower watermain prior to the Tower being put back into service and we would ask that the City Council approve obtaining quotes and having this work completed by the lowest responsible bidder. If a sidewalk connection along Noel Drive between Little Canada Road and Gervais Mill Park is a desired connection at this time or in the future, it would be beneficial to do any necessary work to the watermain at this time because the line is currently out of service. The watermain work could impact the walls and would necessitate either wall repair or relocation of the walls to accommodate the new sidewalk. If the costs for this sidewalk connection are prohibitive in the mind of the City Council then no additional work would be needed other than the valve replacement. We would ask direction from the City Council as to the desired course of action. Options include: 1. Only do the valve replacement. 2. Complete the valve replacement and modify the watermain as necessary to accommodate the future wall and sidewalk work. The watermain depth and associated existing wall impacts are unknown and will only be known at the time of excavation. This option may result in existing wall impacts with the following choices. o Repair the damage to the wall to minimize current costs. o Relocate the walls to accommodate the future sidewalk.
