Topeka, Kansas

2014

A tributary to Shunganunga Creek in Topeka, Kansas runs through the property of Roger and Karen Viola. Streambank erosion and bank instability have created a bank that is encroaching on the backyard and patio of the Viola’s. A solution to repair and stabilize the bank that included a riprap slope was design by another firm. Water Resources Solutions was hired to develop a less costly alternative design.

The project included the repair and stabilization of approximately 130 feet of eroding and degraded streambank. The streambank stabilization design included a vegetated geogrid slope, a rock toe, and a small retaining wall at the top of slope. The opposite bank was regraded and vegetated with native vegetation to provide added channel capacity.

A FEMA “No-Rise” Certification, U.S. Army Corps of Engineers permit and Kansas Department of Agriculture, Division of Water Resources Stream Obstruction Permit, were required for the project. Final plans and specifications were prepared. Construction was completed in summer 2014.
