4.3.5 Groundwater Groundwater needs protection because it is a source of drinking water for the metropolitan area. The Ramsey County Soil and Water Conservation District has written two documents for the County that describe both the status of groundwater in the county as well as the anticipated role of each local government in the protection of groundwater resources. Ramsey County adopted the Groundwater Quality Protection Plan in May 1996. This plan outlines the roles and responsibilities of county and local governments, including watershed management organizations, in groundwater management in the County. The main responsibility assigned to the WMO (now the CRWD) is to adopt the County plan and amend or incorporate this plan into the CRWD Watershed Management Plan. There are several recommendations outlined in the county plan that include participation in wellhead protection programs, sensitive geologic area programs, well sealing programs, and aquifer protection programs. Ramsey County also conducted a Well and Contamination Source Inventory in March 1996. This report's purpose is to show locations of wells in Ramsey County that are active, and those wells that are inactive and unsealed. The CRWD has 18 public water supply wells, approximately 850 active wells, and over 11,000 inactive and unsealed wells. The report also includes information on known sources of • contamination from hazardous waste generators and sites, landfills, leaking tanks, above and below ground storage tanks, and old dump sites. There is also information on Superfund sites, Brownfields, Voluntary Investigation and Clean-up (VIC) sites, Toxic Release Inventory (TRI), and the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS). 4.3.6 Surface Water Resources There are no lakes located within the City of Falcon Heights, but a portion of the storm water runoff from the City discharges to Como Lake. Most of the City's stormwater is conveyed through the City by an existing storm sewer system. There is one Minnesota Department of Natural Resources (MNDNR) Protected Waters and Wetland (MNDNR No. 62-223W) within the City as shown in Figure 11 on page 26. There are a few storm water ponds in the City that also provide water quality and quantity protection. The City's existing storm sewer is shown in Figure 12 on page 27. 4.3.7 Hydrology The City of Falcon Heights is a highly urbanized area. A significant portion of the City that the City has jurisdiction over is impervious and an extensive series of pipes is in place to collect and to convey storm water downstream. The University of Minnesota owns a golf course and agricultural land within the City, but the City does not have jurisdiction • over these areas. The conveyance system in the City is mostly man- TComprehensive Plan UpdateT AFAL000701.00 City of Falcon Heights Page 24
