IADaPTEngineering, Inc. 1 The proposed ground lease area is asphalt covered and adjacent to the retaining wall on the I southem portion of the host parcel. One groundwater monftoring well was observed approximately 40 feet east of the proposed lease parcei in the asphaft parking area. A dry deaners and dental laboratory were observed on the host parcel. These businesses wer� i located in the northeast and southeast comers of the building, respectively, and appear to be in a dovm gradient direction from the proposed lease area. It appears unlikely that any potential environmental impacts from the dental laboratory or the dry deaners would have impacted the ( proposed lease area. The reconnaissance did not reveal readily apparent indications of the following on the host parcei in the vicinity of, or on proposed lease area: underground storage tanks or above ground storage tanks containing hazardous substances; landfills; pipelines; hazardous materials and hazardous waste storage/disposal areas including sumps, pits, drums; dead and chemically stressed vegetation; discarded electrical transfortners and capacitors; constructlon materials suspected to contain hazardous materials, including asbestos; supply wells; obvious locations of past and present chemical disposal. During the concurrent geotechnical evaluation (see Sedion 5.2) of the proposed lease area that included the drilling of one boring, ADaPT personnel did not observe soils tt�at exhibited discoloration or unusual odors indicaGve of a hazardous substance or petroleum release. 7.2 AdJacent Site and Vfcinity Observations I A representative of ADaPT conduded a rewnnaissance of the area surrounding he proposed lease area on April 27, 2000. The purpose of this reconnaissance was to observe land use in the I proposed lease area vicinity and to evaluate the potential for nearby businesses to generate, use, or store hazardous substances that may affect the host parcel. The off-site reconnaissance was non-intrusive with the adjoining propertfes observed from the proposed lease area and public right-of-ways. ADaPT did not observe recognized environmental conditions on other parcels ' immediately adjacent to the proposed lease area. A monitoring well was observed approximately 40 feet east of the proposed lease area. The well is associated with the adjacent gasoline station. The adjacent gasoline station is listed on the Washington State DepaRment of Ecology's (Ecology) LUST list. ADaPT reviewed the LUST file and based on our review the proposed lease I area dces not appear to be impaded by releases from the gasoline station (see Sectlon 8.5). 8.0 STANDARD REGULATORY AGENCY ENVIRONMENTAL RECORD SOURCES Publicly available and practically reviewable regulatory agency reports generated from databases were reviewed with respect to the host parcel and proposed lease area. The reports, obtained from federal, state, and local govemment agenaes, were reviewed in an effort to document any reported environmental concems that have occurred at ihe host parcel or in the surrounding area. Sites or facilities appearing on the reviewed reports, within a certain search distance of the proposed lease area, are discussed below. The search distances ADaPT utilizes for Phase I reports meet those specified in ASTM Practice E 1527-97. The following reports were reviewed (the search distance for each report is listed in parentheses): VolceStream-Masonic Center '�° S' � ADaPT Projecl No. WA00-4747•1 � e
