I I The land use zoning districts in the area are identified by the City of Arden Hills as I-I zoning to the north and south, and R-l (single-family residential) zoning to the west and northwest. Currently, office buildings are located in these areas zoned as 1-1. The City of Shoreview's Comprehensive Guide Plan (approved April 2000) identifies land uses in the study area as medium density (RM) and high density (RH) residential as well as office use. The City of Shoreview's zoning document identifies multi-dwelling residential (R-3) and Planned Unit Development (PUD) zoning in the study area. The existing land uses are consistent with these zoning districts. Potential Environmental Hazards Prior to purchasing the property formerly owned by Control Data Systems, two Phase I Environmental Site Assessments (ESA) were completed for this portion of the site. The 1997 ESA covered Building F and its boilers (see Figure 3) and the 1998 ESA covered the 37.21-acre Control Data Campus in Arden Hills, which includes Building F and adjacent land. The 1997 ESA revealed no indications of recognized environmental conditions. The 1998 ESA concluded that operations on the Control Data Campus did not pose a significant environmental concern. However, it was the recommendation of the 1998 ESA that a limited subsurface investigation be conducted in the vicinity of the former fuel oil underground storage tanks (USTs) and that sampling of elevator hydraulic fluids for polychlorinated biphenyls be conducted. A Spill Prevention Control and Countermeasures (SPCC) Plan and Risk Managcment Plan (RMP) was recommended for the Control Data Systems operations occurring on the site at the time of this ESA. The Guidant Corporation has an SPCC and RMp for their operations. A subsurface investigation in the fonner UST area (identified in the 1998 ESA) was conducted. Fuel oil impacts were noted in two of the boring locations. Further investigation was conducted at these locations and it was determined that the impacts wcre limited to the shallow subsurface soils. The fuel oil impacted soils were removed and the MPCA stated that no further action was required related to the former fuel oil USTs. A liquid oil sample was taken from each of the four elevator hydraulic oil reservoirs. The test results revealed there were no concentrations of poly chi orin at cd biphenyls (PCBs) at or above laboratory method detection limits and therefore, no recommendations were provided for further investigation. No further studies have been completed by Guidant for the rcmainder of the Guidant Campus not included in the aforementioned ESA's; however, in September 2001, as part of the completion of the Arden Hills Local Storm Water Management Plan (February 2002), the Minnesota Pollution Control Agency provided the City of Arden Hills information regarding contaminated site in the vicinity of Arden Hills. No sites of concem were idcntificd on or immediately adjacent to the AU AR study area_ It is not anticipated that other environmental hazards will be encountered on the Guidant Campus site.
