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 been completed on this south phase. The pedestrian bridge across the creek at 62nd Street & Roger Road is open for use. The contractor has completed about 75% of the sod installation. A punchlist of corrections was developed on June 26th. Work remaining includes installation of a small drain near 62nd & Roger, a small section of fencing, raising manhole lids on 4 sanitary manholes, sod on 62nd St and by manholes requiring adjustment and a number of other clean up items which should be completed by mid-July.. The final layer of asphalt is scheduled to be installed in September once sidewalk is installed on the south side of 62nd Street between Ballentine and Goddard.
If you have any additional 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.
