Overland Park Major Storm Sewer Repair

The City of Overland Park, Kansas targets deteriorating infrastructure as part of their annual Major Storm Sewer Repair (MSSR) project. This annual investment maintains and improves drainage in commercial and residential areas across the city. For the 2020 effort, the city chose seven separate sites.

The Affinis team began by analyzing the existing drainage patterns for the seven sites. Then, we worked with the city to develop design solutions. The 2020 MSSR project replaced 2,800-feet of storm sewer and over 40 drainage structures, wing walls, and segments of concrete channel.

While this effort was led by our stormwater group, we leveraged several of our other teams. On West 108th Street, or Site 2, we worked closely with our structural engineers to design a deep curb inlet, because the structure’s geometry required a special design. Site 6 was located along a busy stretch of Shawnee Mission Parkway to replace failed storm pipe. Working with our traffic engineering team, our design included the removal of an existing crash attenuator and associated KDOT permitting. Along Bond Street off West 106th Street, we had help from our structural engineering team to evaluate and design wing wall replacements that had failed. We also collaborated with the city to implement native restoration adjacent to the roadway and wing wall replacements.

Many sites were in back, front, or side residential yards. Our design solutions in these tight quarters reflect a great level of detail to show how properties are impacted by the project, and plans for how each should be restored.
