Located in the industrialized section of the Mill Creek Valley, is North Fairmount. In this neighborhood, a bioswale has been constructed to capture stormwater runoff. The bioswale is not fenced, as it is intended to blend in and beautify the neighborhood.
North Fairmount Urban Water Grant Project
The Denham watershed — part of the Lower Mill Creek watershed — covers 2.1 square miles and includes portions of North Fairmount, South Fairmount, Westwood, and East Westwood.
Every year, about 227 million gallons of combined sewage and stormwater overflow into the Mill Creek from five CSO outfalls: CSOs 8, 10, 13, 14 and 530. Less than 25% of the overflow volume is sewage — the rest comes from stormwater and what used to be natural stream flow.
CSO 10, located on the Mill Creek near the intersection of Beekman and Denham streets, contributes the largest volume of stormwater in this watershed, about 162 million gallons a year during a typical year of rain (41 inches).
What is the North Fairmount Urban Water Grant Project?
MSD was awarded a $72,000 Ohio EPA Surface Water Improvement Fund (SWIF) grant in 2013 to install a bioswale on MSD property south of Denham Street between Linden and Beekman streets. A bioswale is a narrow rain garden that conveys stormwater similar to a drainage swale. MSD is working with the Mill Creek Watershed Council of Communities on this project. Total project costs are estimated at $235,000.
- Main bioswale is about .03 acres in size.
- Landscaping includes native plant species, special soils and layers of gravel.
- Mulch walking paths.
- Educational signage.
- New trees throughout the property.
- Predicted to remove and detain 250,000 gallons of stormwater annually.
