. ~ 4. • Minnesota and State Fairground properties are presumed to be primarily responsible for the high flows during these years because of their dominant share of the total measured flow, and the State Fairground's continued utilization of a combined storm/sanitary sewer system for approximately 53 acres of its total site. To date, the State Fairgrounds has not eliminated its combined sewer flows to the Metropolitan Sanitary Sewer System. The Council recommends that Falcon Heights prepare both a Tier I and Tier II comprehensive sanitary sewer plan for the entire city to specifically address the integrity of the system, the source(s) of the increased flows and projections of future flows to the Metropolitan Sanitary Sewer System from the city. Such a plan would make it necessary for the University of Minnesota and the State Fairgrounds to identify the sources and volumes of flow generated by each entity. It may also serve as the city's response to its 1988 Sanitary Sewer System Statement. Essentially all privately owned land within the city of Falcon Heights has been developed. While total city sanitary sewer flows have exceeded Council estimates, it has not resulted in capacity problems within the Metropolitan Sanitary Sewer System. The city has however, recognized the need to reduce the volume of inflow and infiltration (I/I) within its part of the sanitary sewer system. The city intends to monitor and correct sewer line and manhole deficiencies, and reconstruct those parts of the system as part of city street improvements, or as needed. The city has also indicated its awareness of the presence of direct sump pump connections to the sanitary sewer system. The city intends to evaluate ways of terminating these connections within the system. The Council strongly encourages the city's continued effort in reducing and eliminating these sources of I/I to the Metropolitan Sanitary Sewer System. The efforts will result in an • increase in the longevity of both the city's and MWCC's sanitary sewer systems, and a reduction in wastewater treatment expense for the city. The city has indicated, subsequent to submission of this proposed amendment, its knowledge of two sites on the University of Minnesota property that are served by wastewater holding tanks. The University of Minnesota currently uses at least one of these sites. The Council recommends that the city contact the University to obtain confirmation of sufficient on-going operation and maintenance for each of the sites, and recommend their elimination by connection to the University's sanitary sewer collection system. Housing (Audrey Dougherty) The city has done an excellent job in preparing the housing element of its comprehensive plan. The city has addressed pertinent housing issues by identifying housing market trends, relevant housing issues and specifying housing goals and policies. The plan also clearly defines activities the city will take to implement the housing element. As the city has virtually no private vacant land available for the development of new housing and no immediate need for housing redevelopment, its plan emphasizes the need to maintain the existing housing stock. Council housing policies strongly encourage major efforts at rehabilitation, maintenance and renewal of older neighborhoods. G: W SERUM E17dLS1FALRP1~0116.l2 • 5
