6200 Block of Nieman Road Culverts

Project Description:

The drainage sub-watershed along the Turkey Creek Tributary north of Shawnee Mission Parkway and beneath Nieman Road has a history of flooding businesses and threatening infrastructure including retaining walls and utilities. The Northeast Johnson County Watershed Study completed by Johnson County in 2006 identified two businesses and Nieman Road flooding on this tributary.  The existing double box culvert is undersized and inadequate and is contributing to the flooding of two businesses and inundation of Nieman Road. The proposed project will include replacement of box culverts, vertical walls east to Nieman South project (P.N. 3400), relocation of sanitary sewers and reconstruction of the undermined retaining wall adjacent to commercial enterprises.

Status Details:

The design contract was awarded to George Butler Associates (GBA) on October 10, 2016. Mega Industries LLC was awarded the construction project on June 6, 2017. Construction is about 98% complete and weather permitting Mega is expected to complete the original construction work by the end of April. In May, activities will be concentrated on the north frontage road of Shawnee Mission Parkway as some site stability work is done at the location of the former strip mall.

All major stream channel walls are complete except for final staining touch-up. Construction cones are expected to removed off Nieman Road between Shawnee Mission Parkway and 62nd Street this week. This will reopen the full 5 lanes of traffic at the Nieman Road/ Shawnee Mission Parkway intersection.

The contractor is in the process of restoring the adjacent disturbed private parking lots this week. Once a final sanitary sewer stub-out is replaced, all other final grading and landscaping restoration activities will begin. Mega will then transition to final slope stabilization activities north of the Shawnee Mission Parkway frontage road and restoration will include replacing/ installing curb and parking stall asphalt and seeding the adjacent disturbed area.

The U.S. Corps of Engineers is requiring that the floor of the channel on this section of stream remain natural and not be concrete lined. The final asphalt and lane striping above the new channel crossing of Nieman Road will be completed with the Nieman Road street project.

Construction is expected to be completed in late spring 2018. Traffic patterns on Nieman Road will vary throughout the project.

The Nieman Road street project utility relocation work is expected to begin very soon and this may impact future traffic patterns on Nieman Road.
