The project included site planning and design services for an initial and follow-on phase of a residential and commercial development in Lee’s Summit, Jackson County, Missouri. Site design included full design survey, facility layout planning, grading, design of access roadway & parking, erosion and sediment control plan, on-site utilities, and drainage. A major feature of the project involved an individual USACE 404 permit requiring both onsite mitigation and offsite mitigation credits. The onsite improvements included a significant stream restoration effort between the existing first phase of the development and the current and future Phases II & III. Features included a large energy-dissipating outfall channel was built to mitigate erosion from a large upstream culvert draining several hundred acres. Further downstream, a meandering channel was reestablished and a number of stream barbs were constructed to stabilize the channel and create grade breaks that will encourage formation of pools and riffles in the channel, improving water quality. Also, a three-cell box culvert, designed to reduce sedimentation of the primary drainage channel, was constructed for the access road crossing.
