The purpose of the project is to construct drainage improvements to help alleviate recurring flooding of streets and habitable structures along the Turkey Creek tributary from East of Nieman Road southeasterly to Shawnee Mission Parkway. The Preliminary Engineering Study (PES) dated January 2015 determined the best option for the City to pursue in order to alleviate flooding without just demolishing all the flooding homes and leaving the land vacant.
The upper half of the project has an existing trapezoidal concrete lined channel, the lower portion of the project is an existing natural trapezoidal channel leading to 7 reinforced concrete boxes (RCB) under Shawnee Mission Parkway. The final plans approved by the Governing Body include relocating the southern portion of the project northward and channelizing the stream in a concrete lined vertical wall system. The project also includes construction of a pedestrian bridge at 62nd Street to directly connect this neighborhood with the Nieman Road commercial district. This will alleviate flooding of homes along 62nd Street, allow for redevelopment along Shawnee Mission Parkway and Nieman Road, add a pedestrian bridge, trail and sidewalks and upgrade sanitary sewer along the tributary.

Estimated Project End Date:
The construction contract was awarded to Leath & Sons, Inc. Construction of the new channel has progressed well and the new pedestrian bridge across the creek at around 62nd Street & Roger Road has been installed. The necessary sanitary sewer replacements have been completed up to 62nd Street. The Reinforced Concrete Box (RCB) connection to the west tributary has been installed. Storm sewer work on the south side of 62nd Street has been completed and the majority of curbs, sidewalks, and driveways have been installed along the south side of W. 62nd Street. A good portion of the fencing along the channel has been installed. IN case there are any questions, contact information for those involved with this project are included in the Construction Update attached. Upon completion of the entire Nieman Corridor project, the City will apply for revised floodplain mapping to remove many of the homes along 62nd Street out of the existing Federal Emergency Management Agency floodplain. This is being delayed to completion of all projects as the federal agencies are approaching this series of projects as one improvement.
