-------------------- . . MWCC's long range plans call for Lift Station L-35 to convey TCAAP's wastewater flow. . Conveyance of TCAAP's wastewater flow in Arden Hills' IS-inch gravity interceptor would utilize much of its capacity with little reserve for future growth. . A gravity interceptor from TCAAP to the IS-inch gravity interceptor is not feasible. . The interceptor from TCAAP to Arden Hills would not be cost-effective. City of Sboreview Facilities Research of Shoreview's facilities did not identify any facilities large enough within a reasonable (cost-effective) distance from TCAAP's main lift station. CITRRFNT SITliA1'TON The design of the TCAAP interceptor has been completed. Currently, the U.S. Army is awaiting construction funding. It is anticipated that the 3,750 linear foot gravity interceptor will be constructed during the summer of 1994 and will be put into operation late in 1994. FIJTlTRF. SITlTATTON 1 Because TCAAP has been downgraded to "modified caretaker" status, it is reaso!1able to e~t ~,~ that the facility will be totally abandoned at 'some .point in the future. When TCAAP is.-;. -" . abandoned, the land that it occupies (2,400 acres) will become available for redevelopment. - Although most parties agree that the U.S. Army will ultimately abandon TCAAP ,no one will - speculate on when the property may be available for redevelopment. Currently, a groundwater remediation effort is underway. Although no one can be sure how long the remediation will take, it is speculated that the groundwater remediation effort may take another 40 to 50 years. The U.S. Army, in turn, may not abandon TCAAP until the groundwater remediation has been completed. If TCAAP is redeveloped, it most likely will be redeveloped in some combination of residential, '~ commercial, and industrial development. As mentioned above, TCAAP occupies approximately 2,400 acres. The National Wetlands Inventory Map shows much of the eastern end ofTCAAP to be wetland. Because of restrictions placed on wetland development by the 1991 National Wetlands Act, much of the eastern portion of TCAAP (approximately 600 acres) may not be developable. However, even if this area cannot be developed, approximately I,Soo acres of developable land would remain. Although redevelopment of TCAAP may still. be decades into the future, good planning dictates that some thought be given to providing sewer service for the area when it redevelops. To accomplish this, MSA, Consulting Engineers completed the following tasks: . Reviewed topographic maps provided by TCAAP officials. . Projected future wastewater flows. . . Completed preliminary interceptor sewer layouts. . Contacted representatives of the Metropolitan Waste Control Commission and Metropolitan Council. . Contacted TCAAP officials. 049-2203,feb 520-049-70
