The America Monarch building and a small veterinary clinic adjoining this railroad right-of-way south of the tracks. The America Monarch Corporation Is an older manufacturing business which appears to be currently vacant. • Mixed Industrial and residential to the east—Older manufacturing uses adjoin the Soo Line Railroad right-of-way to the southeast of the subject property. A new Rapid Oil change is located at the northwest corner of Sliver Lake Road and 37th Avenue North. Older apartments are located directly across Sliver Lake Road. A Twin City Federal Bank Is located across Silver Lake Road,directly east of the.First Bank. Predominately commercial uses to the"west—Apache Square is a small,18,000 square foot strip center which is currently occupied only by Domino's Pizza. The remainder of this retell space Is vacant and largely unfinished. Another small strip center Is located west of the subject property along Stinson Boulevard.-Tenants of this strip center Include Gas Unlimited,Fantastic Sam's, Pllgrlm Cleaners,and Farmer's Insurance. Because the site Is zoned Commercial(see Item 28)and the proposed project revitalizes an existing mall,no conflicts with adjacent and nearby land uses are anticipated. Additionally,the proposed stormwater management practices will significantly Improve runoff water quality relative to existing conditions. Environmental Conditions;. As noted In the Phase 1 Environmental Site As (ESA)prepared by Braun Intertec(See Appendix A)In April 1994,six"recognized environmental conditions"were observed on the site. A Phase 2 ESA(See Appendlx B)was prepared In September 1994 to investigate the underground storage tanks(UST)and flammable waste traps identified in the Phase 1 ESA. Each of the six"conditions"and the resulting studles/actlons are summarized below: (1) Apparent Fuel Oil Tank and Former Tire Plus Underground Storage Tanks Waldorf Cleaners Phase 1 ESA. A vent and fuel pipe likely associated with a fuel oil UST were observed along an external wall near Waldorf Cleaners on the south side of the Apache Mall building. Braun recommended a Phase 2 ESA to evaluate the potential for soil and groundwater contamination. Phase 2 ESA: The presence and location of an existing tank was determined. Braun recommended that the unused tank be removed by the owner(Waldorf Cleaners)and that the tank basin be monitored. On September 27,1994 the 1,500-gallon heating oil UST was removed and a petroleum release was discovered. The release was assigned Leak Number 00007877. Remedial investigation Report'(December 1,1994): Braun conducted an additional Investigation to determine the horizontal and vertical extent and magnitude of the remaining soil contamination and to assess potehtlel groundwater Impacts. Multiple soil borings revealed limited contamination. .Braunconcluded that risk to potential groundwater and vapor receptors from the petroleum release at the site appears unlikely. No drinking water wells are located in the Impacted unit within 1/2 mile.downgradlent of the site and a significant confining layer appears to exist between the impacted unit and the upper drinking water aquifer. The source of. contamination at the site has essentlally been eliminated with the removal of the UST systems and 40 cubic yards of contaminated soil. No vapor risk asaoclated with manmade structures was Identified based on the available data. In a letter dated December 23,1994.the Minnesota Pollution control Agency(MPCA)Voluntaryo Petroleum investigation and Cleanup(VPIC)staff stated that the petroleum tank release has• Westwood Professional Services,Inc. ,�•
