Leighton Consulting <br />I (A6) Environmental Services <br />significant data gaps, and offer practical recommendations when data gaps occur from <br />reconnWssance/entry restrictions. <br /> Phase Il Environmental Site Assessments (Phase 11 ESAs) <br /> A kickoff meeting is often held at the outset of a Phase 11 ESA CTO. Available background <br /> information is reviewed prior to the meeting to facilitate discussion of the most suitable <br /> investigative methodologies. A Work Plan for the field investigation is developed, based on the <br /> results of this meeting. The Work Plan scope will be based upon our review of site conditions and <br /> meetings/ discussions with the City. Each Work Plan will include a specific technical scope of work <br />.. developed to best suit the needs of the Project. A draft of the Work Plan will be submitted to the <br /> City's Property Management Consultant and City staff for review and comment prior to issuing a <br />• final Work Plan. If needed, the final Work Plan will be submitted to the appropriate agencies for <br />^ review and approval. All Work Plans will be reviewed and signed by an appropriate licensed <br /> professional (PG or PE) before field implementation. Investigative methods described in the Work <br /> Plan may include one or more of the following tasks: <br />04 • Survey of Buildings, Containers, etc.: Leighton will coordinate with our subconsultant, Vista <br /> Environmental, to perform hazardous materials surveys of buildings and on-site structures. <br />m, <br />Vista is a California Licensed Asbestos Consultant and Certified Lead Inspector. Vista <br /> personnel have performed hundreds of building inspections and have worked closely with <br />era <br /> Leighton in the past. We understand that containers of unknown contents are often <br /> discovered on industrial facilities and Leighton's well-trained staff is equipped to perform <br />ra - <br /> inspection, profile sampling, and characterization of chemical storage containers, such as <br />r.a tanks, drums, and barrels <br /><.. • Geophysical Investigations: Leighton will contract with GEOVlsion for geophysical surveys <br />when appropriate. We have worked closely with GEOVision on similar projects by using <br />^&% surface geophysical investigations to evaluate for the presence of near-surface features, <br />such as USTs, pipelines, or other anomalies associated with the presence of hazardous <br />materials. Surface geophysics can also be applied to clear locations for underground <br />utilities and other structures prior to invasive work, such as drilling and trenching. <br />CITY OF SANTA ANA I RIGHT OF WAY CONSULTING AND RELATED SERVICES ! 20 <br />'?' 25C-92
