WRS is providing engineering design for construction and bid documents to address active bank erosion and resulting instability along the left descending bank of Brush Creek between State Line Road and Ward Parkway.

Shawnee Mission Parkway — a major thoroughfare carrying heavy traffic volumes daily — parallels Brush Creek at the top of bank along the project reach and is being threatened by the erosion. The proposed design — developed by WRS at a concept lever under previous subcontract — includes using longitudinal peaked stone toe protection and rock vanes to protect the left bank against erosion. To ensure long-term stability, WRS developed a 2-D model to analyze the flow patterns and erosive forces along the reach and a 1-D hydraulic model for the required FEMA no-rise certification. In addition to the streambank stability improvements, the project team looked at solutions to improve sediment transport through the State Line Road bridge.

WRS’s project execution included assessment of existing conditions, site evaluation, geologic investigation, geotechnical data collection oversight and analysis, oversight of topographic survey conducted by RIC, evaluation of previous concept design solutions, development of final design solution, slope stability analysis and solutions design, hydrologic analysis, hydraulic modeling using 2-D HEC-RAS, FEMA No-Rise modeling using 1-D HEC-RAS, utility relocation planning, real estate easement acquisition planning, construction cost estimation, and preparation of final plans and specifications.
