EXHIBIT "A" SCOPE OF SERVICES Consultant understands that in order to comply with grant funding conditions, environmental studies need to be completed to assess whether soil and groundwater below the property is chemically impacted. The Phase II ESA services described herein are being recommended as an initial phase of study. The need for subsequent studies will be based on the findings of these fields studies, and comments (if any) that may be provided by the local regulatory authority, San Mateo County Environmental Health Department (SMCEHD). The scope of initial Phase II ESA services is described below: Plannina, Permittinq and Field Work Consultant will complete a focused Phase II ESA investigation using standard industry practices, including utility clearance, City and County permits, sample collection, sample handling, and chemical analyses. For budgeting purposes consultant will assume that three borings/probes will be completed, with one of the locations being within the City of Redwood City Right-of-Way. Drilling within the Right- Of-Way will require posting of a bond and completion of an engineering permit application, in addition to San Mateo County environmental permit requirements. Prior to submitting permit applications Consultant will conduct a site visit to observe for obvious utility and use restrictions within the proposed boring locations. Consultant will retain the services of a utility locator to screen the areas where borings may be placed to assist in location selection. The consultant will also contact the City of Redwood City for information regarding known utilities in the area of the work. Consultant will then prepare permit application packages and submit them with required initial fees. Once the permits are approved Consultant will retain the services of a licensed drilling contractor to advance the three probes. If concrete coring is required consultant will also retain the services of a coring contractor to complete the pre-drilling of the probe holes. Groundwater is expected to be shallow at the site, and as such consultant will extend the probes to a depth of about 15 feet below ground surface (bgs) to facilitate collection of both soil and grab groundwater samples. Soil samples will be collected continuously in the probes to evaluate subsurface conditions. Consultant's field staff will screen soil samples with a photo-ionization detector, an instrument that detects the presence of organic vapors such as petroleum hydrocarbons and volatile organic compounds (VOCs), and log each boring in accordance with the Unified Soil Classification System (USCS). Selected soil samples from each probe will be retained for chemical testing. Upon completion of soil sampling, 1-inch diameter slotted PVC well casing will be installed in each probe holes to facilitate groundwater sampling. Groundwater samples will be decanted from pre-cleaned bailers into laboratory prepared containers. Soil and groundwater samples will be labeled and stored in a chilled ice chest, and will be transported under chain-of-custody documentation to a state-certified laboratory for testing. Upon completion of sampling, the probes will be sealed according to permit requirements and under the observation of SMCEHD. The City of Redwood City will also observe the backfill placement and sealing of the probe in the right-of-way. The consultant will assure that all soil cuttings and water generated for this field effort will be drummed, labeled, and temporarily stored onsite pending offsite ATTY/AGR/139/1306 MAIN STREET PHASE II ENVIRONMENTAL SITE ASSESSMENT REV:09-07-12 VR Page 10 of 73
