We completed bridge design and flood control work for the Monitor Square subdivision in Overland Park, Kansas, within the Federal Emergency Management Agency regulatory floodplain.

To replace a hydraulically-deficient box culvert, we designed a new 89-foot NU-girder bridge. This design also accommodated four traffic lanes with dedicated pedestrian sidewalks on 103rd Street over a local creek. We reconstructed the immediate approaches to raise the profile to provide sufficient clearance. Additionally, we were able to improve horizontal sight distances to an adjacent intersection and improve drainage at the ends of the new bridge.

Our services also included surveying, environmental reviews and permitting, hydrological and hydraulic analysis, channel design, geotechnical investigation, and public involvement.The winning construction bid for this project came in just under our estimates and was funded through the Johnson County Stormwater Management Program and the Stormwater Management Advisory Council (SMAC). Construction was completed in January 2017.
