Shawnee Creek Drainage Improvements

Switzer Road to Knox Avenue, Merriam, Kansas

Affinis was selected to make a number of drainage improvements to Shawnee Creek. The project involves replacing three culverts in separate locations and the use of bridges to increase conveyance and protect adjacent homes and roadways from flooding. In addition, a stretch of existing concrete channel will be widened and extended further upstream to provide flood protection to an adjacent apartment complex. Our team will stabilize the stream banks using a combination of riprap and segmental block retaining walls at various locations.

With RCB replacements at three streets, we wanted to minimize detours for the residents by getting the crossings open as soon as possible. We determined precast arch bridges were the optimal solution for two locations. We used segmental block retaining walls in key locations to stabilize eroding banks and improve the channel capacity. The walls are an attractive option and give residents usable yard space that’s easier to maintain.
