Overview
Horner & Shifrin provided topographic survey and hydraulic and civil engineering design for a new storm sewer system to provide relief to a residential property from flooding occurring at the downstream end of a culvert draining water from a detention basin.
The property owner’s previous solutions were insufficient to keep the stormwater from backing up into the basement, and the City decided to provide public infrastructure. To collect the stormwater, a double inlet was placed near the culvert end, situated to avoid existing public utility conflicts, and surrounded with reinforced turf mat. The inlet was drained below grade to a downstream creek, with additional inlets places along the alignment. Additionally, a swale was created for overland flow in the event the piped system became inundated. Design plans, specifications, easement documents, and cost estimates were provided for permitting and construction. Survey documents were provided for easement acquisition.
