7th St to Boone's Lick Stormwater Upgrade - 17STM23
Construction Ward - 2
Beginning in the 1940’s, a northern branch of Blanchette Creek was incrementally rerouted from its natural streambed into an assortment of culverts & tunnels. This branch of Blanchette Creek has a catchment area extending northwest from the intersection of Boone’s Lick Road & 5th Street to the Lindenwood University Campus; in total, around 170 acres of residential, commercial, church, and university owned parcels drain through this network of tunnels & pipes.
The existing pipes and box culverts do not adequately convey storm water flows, and cause frequent flooding to homes along the storm sewers route between Perry Street & 5th Street. Additionally, significant portions of the conveyance system are beginning to deteriorate and are structurally deficient. Of note, the existing system passes under or near several homes and may not be located within its dedicated easement in several locations. The selected design consultant will be responsible for determining the pipe sizes, inlet spacing, routing, and final design of the stormwater conveyance system. Design will also include utility coordination, impacted sanitary or waterline design, and an alternatives analysis that could include a combination of up-sizing the existing system, rerouting part of the flow, detention, and property acquisitions.
