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 with a conspan, 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.

Estimated Project End Date:
The design contract was awarded to George Butler Associates (GBA) on October 10, 2016. Mega Industries LLC was awarded the contraction project on June 6, 2017. Construction is expected to start July 10, 2017 and be completed in late spring 2018. This project will include the removal of several commercial buildings along the north frontage road of Shawnee Mission Parkway and a former gas station on Nieman Road. 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.
