Specifications include, but are not limited to: The “Pumpkin Patch” stormwater management facility (Facility) is in southwest Sun Prairie, just west of Highway 151. Situated between South Mallard Drive and Schneider Road, this Facility is an 8-acre wet detention basin/pond. The Facility is considered a regional stormwater management facility as it receives urban stormwater drainage from impervious landscapes within a large area of commercially and residentially developed land within the City of Sun Prairie (City). The City of Sun Prairie wishes to have native vegetation installed on the basin side slopes with the hope that taller and denser vegetation serves as a deterrent to the general public attempting to access the water within the facility.
