Commonwealth Rip Rap Replacement Project and Hurricane Harvey Update

After receiving four bids, First Colony LID 2 has signed a contract with low bidder, Harper Brothers Construction, to replace the existing concrete rip rap and other miscellaneous rock at the Pendleton, Trent, Warwick, Knightsbridge, and St. Michaels culvert crossings along Commonwealth Boulevard.  Starting on Wednesday, November 29, they will begin replacing the existing rock with limestone to improve the erosion control at each location while creating a more consistent look along Commonwealth. The entire project is scheduled to take 45 days. During construction, portions of Commonwealth and the cross streets (single lanes) could be temporarily closed.  Below is a sample of the limestone that will be installed.

In response to Hurricane Harvey, the Board continues to work with the District Engineer, Jones|Carter, and Operator, LID Solutions, to evaluate ways to reduce the risk of flooding by increasing the District’s response and resiliency during these extreme events. Based on the updated Capital Improvements Plan (CIP), the Board has authorized the Engineer to design and bid the installation of a third stormwater pump and the replacement of the existing backup generator and miscellaneous controls at the pump station. The proposed improvements will increase the District’s pump capacity and enhance the District’s response time and operation during events. The design phase, with agency approvals, could take up to 4 months with an anticipated construction start in Spring/Summer of 2018.
