Crawford Farms in July 2015
Ever wonder what exactly enters your storm drains and makes its way into the waterways? Next time there is a significant rainfall, take a look at the nearest forebay–pollutants including trash, chemicals, and oils are swept through the storm drain and directly into the waterway via the forebay. This rush of pollutants during a rain event is known as the “First Flush.”
Crawford Farms in 2013
Dysart Run is a 5 mile long stream that enters the Blacklick mainstream in Reynoldsburg. Dysart drains a watershed of 4.2 sq. mi. Over the past 25 years, construction of subdivisions, apartment complexes, condominiums, shopping centers, commercial facilities and parking lots has resulted in a large area of hard surfaces in the watershed. Much of the rain that falls onto these surfaces drains into the creek without passing through any stormwater control features.As a result of the runoff from these hard surfaces, Dysart Run does not meet the water quality standards established by the Ohio EPA. In addition, the creek becomes a raging torrent during larger rain storms, eroding its banks and threatening homes along it.
The runoff near Dysart Run has to be intercepted at multiple locations. The recently created stormwater treatment wetland in Crawford Farms Park is one of those places. Crawford Farms is a subdivision off of Waggoner Road on Columbus’ east side, constructed from 1997 to 2003. The stormwater basin receiving runoff from 32 acres of the subdivision was excavated in Crawford Farms Park, which is owned by the City of Columbus. Of those 32 acres, approximately 11 acres is hard surface (roads, driveways, roofs etc.).
