Horner & Shifrin provided topographic survey and civil engineering design for stormwater improvements in a residential neighborhood experiencing yard flooding and erosion. Frequent and excessive runoff has resulted in flooding of basement entry garages, and residential property owner improvements have disrupted drainage across properties. The project includes approximately 150 feet of piped stormwater improvements and inlets to collect stormwater at low points and convey it underground to the existing storm sewer system. Project scope included locating utilities in the back yards to coordinate minimal disruption, locating sewer away from existing retaining wall to prevent bearing on the pipe and disruption during construction, and easement documentation for Metropolitan St. Louis Sewer District approval.
