• Land Use There are two large state owned lands within the City of Falcon Heights: State Fairgrounds and University of Minnesota - St. Paul Campus. The CRWD has summarized the existing storm water systems for both properties. Figure 13 on page 33 provides the current Land Use Map. State Fairgrounds Stormwater drainage from most of the Fairgrounds property flows to the University of Minnesota-St. Paul Campus. The storm sewer system for the exhibit area in the south and east portions of the Fairgrounds discharges to a 42-inch pipe connected to an open ditch on University property at a point south of Commonwealth Avenue and north of Como Avenue. The north and west portions of the Fairgrounds, mainly parking lots and a portion of Machinery Hill, flows to pastureland on University property. A storm water detention basin south of Larpenteur Avenue receives flow from two large, unpaved Fairgrounds parking lots and a portion of Larpenteur Avenue. As part of reconstruction of a section of Larpenteur Avenue in 1998, roadside ditches were replaced by a piped outlet to the Fairgrounds basin. During the project, additional basin excavation was completed. Pond size and outlet characteristics are available from Ramsey County Public Works. The flow from Larpenteur drains a total of 123 acres, which also includes runoff from the University agricultural fields north of Larpenteur and east of Fairview as well as other • city runoff. Outflow from the basin enters a ditch to the University Animal Science pastureland. Water infiltrates in the pastureland over time. Very high water conditions (not reported by Fairgrounds staff) would result in surface runoff down Randall Avenue to the ditch south of Commonwealth referenced above. At the request of the MPCA, the Fairgrounds initiated amulti-year combined sewer separation program in 1995. All of the animal exhibit buildings were separated early in the program. The sewer separation program was completed in 2002. Two additional areas have been identified since 2002 and are scheduled to be completed in 2007. University of Minnesota-St. Paul Campus Drainage from University property south of Larpenteur Avenue flows to a DNR Protected wetland located in the southeast corner of the campus. The agricultural fields have an extensive drainage the system which is connected to the University storm sewer system. Piped flow from Falcon Heights crosses Larpenteur Avenue at Gortner Avenue and joins the University storm sewer system at Folwell Avenue. An agreement was executed in the 1980's between the City of Falcon Heights and the University related to these flows. The pipe system from the northern portion of the campus (discussed above) outlets to the open ditch at Commonwealth Avenue, which also receives the flow from the Fairgrounds. University staff indicates that a parking lot near this junction is flooded following larger storm events. The University wetland outlets to the Saint Anthony • Tunnel system.
