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 90% complete and weather permitting Mega is expected to complete construction by mid-April.

Concrete walls in the channel have been constructed including staining and handrail installation. Traffic patterns are being adjusted this week and traffic will once again be on the west lanes. The temporary shoe-fly on the east right-of-way will be removed, curb and gutter installed and final restoration of parking lots, curb and gutter, landscaping and sod will occur over the next 6 weeks. Once the east curbline of Nieman is restored, we expect to be able to reopen the full 5 lanes of traffic at the Nieman Road/ Shawnee Mission Parkway intersection.

Restoration of sidewalk and curb along the north frontage road of Shawnee Mission Parkway is also planned to wrap up the project. The US. Corps of Engineers is requiring that the floor of the channel on this section remain natural and not be concrete lined. Mega will be pacing final erosion control along toe of new walls and grading the channel floor to the permitted grades. Additional work associated with this project still to be completed includes the mow strip and handrail on culvert wingwall near the new Stag's Creek Development on Shawnee Mission Parkway north frontage road. 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 but it is our intent to keep 2-way traffic open at all times through this project area.

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