RECOMMENDATION: ~~Adopt Resolution FINANCIAL STATEMENT: Cost of study not to exceed $6,800. DESCRIPTION: As part of the 1990-91 Capital Improvement Program, the City is proposing to begin the work on the Dublin Boulevard Extension by purchasing the necessary right-of-way for five (5) parcels between Dougherty Road and the Southern Pacific Railroad Right-Of-Way. Staff is concerned that there may be "hazardous" waste on the two parcels where engine work has taken place (the Valley Boat House and Curtis Dodge). As part of the purchasing price evaluation of these two parcels, the City requested proposals from four (4) engineering consultants for Environmental Site Assessments. The Consultant's duties include investigation of past and present activities for the two lots, and the adjoining and neighboring properties up to one-half mile distant, for underground fuel storage tanks or other environmentally hazardous materials. This first-phase study would serve to identify potential liabilities which may be further addressed in subsequent investigative phases. If hazardous wastes are found on these parcels, it could effect the value and purchase price of the two parcels. On May 6, 1991, the Public Works Department received three (3) proposals from qualified engineering consulting firms. After reviewing all three proposals for past performance, experience and knowledge of the area and site, ability to complete the project in a short time, and equipment and staffing, Staff considered Terrasearch, Inc., as best able to fulfill the City's requirements. Therefore, Staff recommends that the City Council adopt the Resolution approving the Agreement with Terrasearch, Inc.

PROPOSAL City of Dublin Page 3 of 13 Environmental Site Assessment Dublin Blvd. Extension May 6, 1991 1.1. Project Description 1. INTRODUCTION The City of Dublin is in the process of extending Dublin Boulevard east of Dougherty Road and plans to purchase a portion of the Valley Boat House and vacant Curtis Dodge Dealership lots for this extension ("Site"). TERRASEARCH, Inc. hereby responds to an invitation to submit a proposal to perform an environmental site assessment to determine if the soil is contaminated at the Valley Boat House and vacant Curtis Dodge Dealership lots in the City of Dublin. The invited scope of work includes: Task I - Preliminary Site Assessment Phase-1 Task II - City's Option to Request Borings and Analyses 1.2. Objectives The following is a'summary of project objectives: Perform a non-intrusive determination of present environmental and health risk at the Site from past and present Site usage, and surrounding area to one- half mile distant; If optioned by City request, complete a minimum of six (6) soil borings to depths above the water table. Collect soil samples at least every five (5)-foot interval or at significant stratigraphic changes. Analyze the soil samples, or composites of discrete samples, for constituents known or suspected as determined from Task I or other determinations as requested by the City. If optioned by City request, collect water samples for analysis..Water samples would be collected by an initial screening technique, and such a technique would not serve as permanent groundwater monitoring wells. Proposal No. PE910503 TERRASEARCH, Inc. PROPOSAL City of Dublin Page 4 of 13 Environmental Site Assessment Dublin Blvd. Extension May 6, 1991 Prepare a report to discuss a preliminary assessment of environmental conditions at the Site and within one-half mile. Optionally include data and evaluations related to soil borings and samples. 13. Previous Work We are not aware of previous environmental assessment reports for the subject Site. Terrasearch, Inc. has completed environmental and geotechnial investigations for certain adjoining and neighboring properties that are within one-half mile to the Site. The following is a summary of previous work by Terrasearch, Inc. for properties in proximity to the Site: "Soil Sampling for Pesticide Contaminant Testing", June 6, 1988, Scarlett Court, Dublin. Investigation included soil borings and chemical analysis for pesticides and PCB's. o "Soil Sampling for Pesticide Contaminant Testing", March 21, 1988, Sierra Lane, Dublin. Investigation included soil borings and chemical analysis for pesticides and PCB's. "Soil & Geologic Investigation on Proposed Industrial Park, Dougherty Road & Sierra Lane, Dublin", November 1976. Investigation included borings, testing, literature review, and data analysis. 4. Ongoing geotechnical work related to Dublin extension. 2. TASK I - PRELIMINARY SITE ASSESSMENT - PHASE I 2.1. Property. Records Search We would review reasonably available recorded chain of title documents regarding the Site to include such information as deeds, easements, land contracts, leases, assignment of leases, covenants, condition, restrictions, and recorded environmental leins for the past approximate 50 years. We would also request to review existing and past records related to businesses operating on the Site. Proposal No. PE910503 TERRASEARCH, Inc. PROPOSAL Cit7 of Dublin Page 5 of 13 Environmental Site Assessment Dublin Blvd. Extension May 6, 1991 2.2. Aerial Photograph Interpretation Aerial photographs which can be readily, obtained would be interpreted with emphasis on actual or potential use of chemical and disposal of hazardous materials, or changes in land uses and anomalous photographic density and contrast changes over time. Comparative interpretation would depend upon the availability, scale, quality and type of photographs. We would attempt to review stereo photographs whenever possible. Our interpretation would include a detail evaluation within 1/2-mile radius from the Site and a more general interpretation for an area approximately one (1)-mile radius from the Site, depending upon the scale of available photographs. We would seek copies of photographs for the past approximate 50-years. 2.3. Agency Records Search We would review applicable Federal, California, and local agency records and, depending upon availability, would assemble a compliance history of the Site. We would seek documents from such sources as the Environmental Protection Agency, Water Quality Control Board, Department of Health Services, Office of Emergency Services, Air Resources Board, Department of Transportation Fire Department, Planning Department, Engineer's office, and water or sewer authority. 2.4. Interviews Personal or telephone interviews would be conducted to gather information on the present and past use of the Site. Our interviews with present and past landowners would seek information regarding such subjects as, previous buildings, underground tank locations, past uses of surrounding lands, violation citations, locations of chemical materials storage, general history of the Site, and previous owner names and present location. We would interview local officials, such as, fire, health and water staffs to seek information on possible hazardous mater/als spills or emergencies, and to identify unusual occurrences or situations that may effect the Site. 2.5. Environmental and Health Risk A general risk appraisal according to LUFT guidelines can be used to determine how much soil needs to be removed or to what level the soil should be cleaned up. Proposal No. PE910503 TERRASEARCH, Inc. PROPOSAL City of Dublin Page 6 of 13 Environmental Site Assessment Dublin Blvd. Extension May 6, 1991 Remedial action must be approved by the regulatory agencies. Should it be determined that contamination, if any, would pose a health risk due to direct exposure, remedial action would be proposed to limit or eliminate such exposure. At this time, such appraisals cannot be outlined until soil analyses are completed. 2.6. Report A Final Report on the preliminary environmental site assessment would be submitted and include a summary of findings, conclusions, and recommendations regarding the environmental site assessment. 3. OPTIONAL TASK II - BORINGS AND ANALYSES 3.1. Soil Borings and Samoling 3.1.1. Number and Locations A minimum of six (6) soil borings would be proposed in locations to be further defined by the City or as based on information to be collected during the preliminary environmental assessment. For planning purposes, we have assumed three (3) borings each would be located within the Valley Boat House-and Curtis Dodge properties. We have also assumed that only petroleum hydrocarbons, such as, gasoline and diesel, would be analyzed in soil or water samples. Should it be necessary or advisable to analyze for other constituents based on new information as a result of the preliminary environmental assessment, we would discuss our proposed analyses with you. The purpose of the borings would be to collect soil samples for analyses of petroleum fuel hydrocarbons. Borings would be drilled to depths immediately above the water table. Two (2) soil samples would be collected at five (5)-f0ot intervals in each boring. Each sample would be composited by the laboratory and one (1) analysis would be performed on each composite for total petroleum hydrocarbons. Should the composite analysis indicate detectable fuel hydrocarbons, a discreet analysis would then be performed on each sample. The total number of proposed soil samples for analysis would be twelve (12) and the total proposed composite analysis would be six (6). TERRASEARCH, Inc. Proposal No. PE910503 PROPOSAL City of Dublin Page 7 of 13 Environmental Site Assessment Dublin Blvd. Extension May 6, 1991 It is understood that water samples may be requested. Preliminary information suggests that water may be encountered near 8 to 10-feet depth. We would collect samples using a Hydropunch device, which is driven into the soil below the groundwater. Following collection of the water sample, the pipe and Hydr°punch are removed. This technique is designed to provide an initial screening of water quality. It is not acceptable for collecting groundwater samples related to suspected or known contamination. Our schedule and cost estimate include the field and laboratory work related to collecting water samples using this technique. 3.1.2. Methods and Procedures Borings would be completed with nominal 6-inch outside diameter, steam-cleaned, hollow-stem augers. Drill cuttings would be placed in 55-gallon drums which would be labeled showing boring number, date filled, and City contact person. Should the results of soil sampling indicate that soil in the barrels is contaminated, the City would be responsible for proper disposal or remediation of the soil in the barrels and such disposal tasks are not part of this Proposal. During drilling, soil would be classified according to the Unified Soil Classification System and ASTM 2488. Relatively undisturbed soil samples would be collected during drilling per ASTM D-1568 by a clean drive sampler with three (3) inside 2.5-inch by 6-inch brass sample retainers. The drilling sampler would be driven 18-inches with a 140-pound hammer falling about 30-inches. The hammer blows for each 6-inches of driven material would be recorded and used to describe the general consistency or density of the soil sample. Soil would be extruded from one retainer, examined and classified. The retainer with soil to be analyzed would contain no headspace and both ends would be immediately covered with aluminum foil, capped with a polyethylene lid, taped with aluminum coated fiber tape, labeled with sample number, date and time collected, and requested analysis, and placed in a closed ice chest containing 'blu-ice' for delivery to Sequoia Analytical- Concord, California Department of Health Services certified laboratory number 1271. All samples would be accompanied by a chain-of-custody and request for analysis which would be signed and dated at the time of transferring possession of the samples by each person authorized to turn over and receive the samples. Proposal No. PE910503 TERRASEARCH, Inc. PROPOSAL City of Dublin Page 8 of 13 Environmental Site Assessment Dublin Blvd. Extension May 6, 1991 Non-disposable drilling and sampling equipment, including augers, would be cleaned with steam or triple rinsed with Alconox detergent solution and air dried on-site. Waste cleaning water would be placed in 55-gallon barrels, labeled and retained on Site for disposal or remediation by the City and such disposal tasks are not part of this Proposal. A Geologic Log would be completed for each boring to include soil classification, moisture content, and field observations about apparent soil contamination. All borings would be abandoned and backfilled from total depth to the surface with a bentonite-grout mixture. 3.1.3. Laboratory, Analyses All soil samples would be analyzed for total petroleum hydrocarbons ("TPH") as diesel ("TPHd"), gasoline ("TPHg"), benzene, toluene, total xylenes, and ethylbenzene ("BTXE"). These proposed analysis may have to be revised based on information to be collected during Task I. 3.1.4. Data Analysis Generally, if BTXE levels in soil are below detection limits, and TPH is below 10 parts per million ("ppm"), a General Risk Apprais_al is not necessary because the regulatory agency considers the leaching potential of pollutants from the soil to be below cleanup levels. However, each site is uniquely reviewed for specific characteristics that would allow the agencies to determine if further cleanup is necessary. 3.1.5. Recommendation for Further Action If soil contamination is found, remedial action would be proposed to the City, which could include such methods as, aeration, bioremediation, or disposal to a proper landfill. 4. SCHEDULE We anticipate that our Task reports for your review would be completed within the schedules shown below which we would begin upon your written authorization to proceed.

AGREEMENT TI's services will be performed, our findings obtained, and our recommendations prepared in a manner generally exercised by members of the profession under similar conditions at the time services were rendered. Findings will apply only to present Proposal No. PE910503 TERRASEARCH, Inc. PROPOSAL City of Dublin Page 13 of 13 Environmental Site Assessment Dublin Blvd. Extension May 6, 1991 conditions, and opinions expressed will be subject to revision when additional or new information is submitted in writing to us after our Final Report is completed. This warranty is in lieu of all other warranties, either expressed or implied. It is possible that exploration will fail to reveal the presence of hazardous materials at areas where hazardous materials were assumed, suspected or expected to exist. Client understands that TI's failure to discover hazardous materials through appropriate and mutually agreed-upon sampling techniques does not guarantee that hazardous materials do not exist at the Site. Similarly, a Site which in fact is unaffected by hazardous materials at the time of TI's exploration, may later, due to natural causes or human intervention, become contaminated. Client agrees that it will not hold TI liable for failing to discover hazardous materials whose exact location is not possible to foretell from the surface, or for failing to discover hazardous materials which in fact did not exist at specific sampling locations at the time such samples were obtained. This Proposal is valid for approval within seventy-five (75)-days. If not accepted within this time period, it will be subject to a re-evaluation and modification may be made to our scope of services, schedule, cost estimate and our Fees for Professional Services.
