Explanation
The Department of Public Utilities entered into a contract with Watershed Organic Lawn Care for the purpose of inspecting the performance of, and maintaining the City’s bio-retention basins. The City of Columbus is committed to investing in green infrastructure. As part of this commitment, the City has built a number of bio-retention basins in the right-of-way and/or on City owned property.
Bio-retention basins are engineered, shallow depressions that treat stormwater runoff using pollutant removal mechanisms that function in natural ecosystems: settling, filtration, absorption, microbial breakdown and nutrient assimilation. Surface runoff is directed into the bio-retention area where it temporarily ponds before infiltrating through mulch and a soil media planted with vegetation. The infiltrated water percolates into soils and, if necessary, enters a perforated underdrain that discharges into a water body or storm drain system.
The City is currently responsible for the maintenance of 6 sites with 98 basins located in or around the Riversouth area of downtown, W. Broad St. at Starling called Group A. There are 36 sites with 88 basins/wetlands and 20 swales located at Griggs, O’Shaughnessy, Hoover Reservoirs, Idlewild Drive, American Addition, Crawford Farms, Watershed Roadway Improvements Part 2 at Hoover Reservoir and Watershed Roadway Improvements Part 3 at Griggs Reservoir, Smokey Row Booster Station Drainage Project, Dublin Road Water Plant Treatment Capacity No. 3 and Dublin Road Water Plant Treatment Capacity Increase, the Barthman Parsons Blueprint Green Infrastructure Pilot Projects Phase I & II, Brentnell Avenue and Bar Harbor, Blueprint Clintonville Glenmont Avenue, Briggs Road Detention Basin retrofit, Reservoir Pollution Reduction Project at Hoover Reservoir at Twin Bridges site 24, American Addition Phase 2&3, and Weisheimer Road called Group B. Each site may have multiple basins, swales, or other types of green infrastructure...
