The Van's Road Detention Pond was constructed in 2001 by the Garners Creek Storm Water Utility. This Detention Pond is located within the south central portion of the Garners Creek Watershed. Approximately 582 acres or 10 percent of the Garners Creek Watershed drains into the detention pond. Storm water runoff is carried to the detention pond by road ditches, storm sewers, culverts, drainage channels, and streams.
The Van's Road Detention Pond improves downstream flooding and stream bank erosion by reducing peak flow rates. Storm water runoff is temporarily stored within the detention pond and slowly released into the navigable stream located west of CTH "N" and north of Hearthstone Drive. The detention pond release rate is controlled by the outlet structure located along CTH "N". During a 100-year rainfall event, the 17-acre detention pond provides 2.4 million gallons of storage volume and reduces peak flow rates by 68 percent. During dry weather, the permanent pool of water has a surface area of 3.6 acres and a maximum depth of 10 feet.
