Painesville, Ohio


Environmental Design Group’s improvement recommendations created greater capacity for the environment to manage stormwater and reduce flooding.

Mentor Avenue/Jackson Street Storm Sewer Improvements

The intent of the project was to incorporate the necessary stormwater improvements to reduce/eliminate ongoing intersection and street flooding. The design process confirmed the need for the installation of 1,000 linear feet of 18” and 24” storm sewer along Jackson Street and 800 linear feet of 24” storm sewer along Mentor Avenue.

Environmental Design Group was hired to design stormwater improvements for a portion of Mentor Avenue and Jackson Street within the City of Painesville. Using preliminary design information from a previous stormwater model and subsequent report, the design process included a review of the stormwater drainage watershed area, the development and review of the stormwater calculations for various storm events, the impact neighboring streets had on intersection drainage, catch basin spacing with spread calculations of the stormwater along the curb line, and the sizing of the storm sewer collection system for the design storm event.

In addition to the storm sewer improvements, the project included a detailed field inspection (following ODOT requirements) and subsequent design improvement recommendations for the preservation of a historic culvert that conveys Pebble Branch under Jackson Street.
