N%000 Monte Vista Entitlement,Inc. �. Phase I ESA Peer Review and Limited Phase lI ESA Report November 18,2003 Page 2 �• Phase I ESA Peer Review and Review of Sanborn Fire Insurance Ma s Condor reviewed the Phase I ESA report dated December 2000 prepared by Geocon Consultants, Inc. for the site. The report indicated that the Police Department was conducting police dog training in the basement of the building at the time of the site reconnaissance. This may have interfered with the reconnaissance of the basement. The report indicated Sanborn Fire Insurance Map information for parcel 149-180-07 was not available for the 1917 and 190 maps. Condor reviewed Sanborn Fire Insurance Maps for the years 1895, 1917, and 1950 through the San Jose Public Library Internet site. Coverage was available for all six parcels on all three maps. No USTs or I" aboveground storage tanks were identified on any of the site properties or any adjoining properties on any of the Sanborn Fire Insurance Maps. V Site Reconnaissance Condor conducted a site reconnaissance on the sidewalks in front of each parcel. Potential UST fill connections were noted on site in the sidewalk on the west side of parcel 149-200-01 and on the north L" side of parcel 149-200-02. An apartment building is located on the parcel immediately north of parcel 149-200-10. The south side of the apartment building is on the property line. A potential UST fill connection was noted off site in the sidewalk on the w st east of the apartment building and immediately �. north of the property boundary with parcel 149-200-i0. A 3/,inch diameter pipe that may be a tank vent was attached to the wall of the apartment. A slumped area with an asphalt patch near the center of parcel 149-200-09 was noted as a potential UST or former UST location. La A reconnaissance of the basement of the buildings on parcels 149-200-01 and 1.49-200-02 was conducted on July 31, 2002. The St. Vincent's Thrift Shop is located in the buildings. Mr. Bill Rapinsky of the Thrift LW Shop provided access to the basement and accompanied Condor personnel during the reconnaissance. Six alcoves with approximately four foot by four foot openings in the concrete floor were present in the wall on the north side of the basement. The opening in the alcove in the northwest corner of the basement contained soil with an apparent oily residue. L. An abandoned elevator shaft located near the south wall of the basement contained debris that may contain asbestos. An active elevator near the southeast corner of the basement is operated by a hydraulic +� lift. Hydraulic oil was present at the base of the hydraulic lift. No evidence of fuel lines or fuel storage tanks was noted in the basement. Lo Mr. Rapinsky pointed out a pipe that he believes may be a UST vent on the outside of the east wall of the building on parcel 149-200-03. He indicated the vent may be connected to a UST in the parking lot of parcel 149-200-10 south of the location of the previously removed UST. Limited Phase 11 ESA 4 A ground penetrating radar (GPR) study was conducted on the sidewalks in front of each parcel, on the slump area in parcel 149-200-09, and near the northeast corner of parcel 149-200-10 in the area of the potential UST on the adjoining property. The results of the GPR survey are presented in a letter report, Ground-Penetrating Radar Investigation, dated August 1, 2002. A potential UST was identified beneath the sidewalk in front of the apartment building immediately north of parcel 149-200-10. A potential UST was identified beneath the sidewalk in front of parcel 149-200-01. This potential UST is located next to �. the potential UST fill connection identified during the site reconnaissance. The slumped area with the asphalt patch on parcel 149-200-09 was surveyed. The GPR data indicate this area correlates to a former excavation that was backfilled. w W CONDOR LO
