Leighton Consulting <br />I(Ab) Environmental'SerVices <br />significant data gaps, and offer practical recommendations when data gaps occur from <br />reconnWssance/entry restrictions. <br />Phase II Environmental Site Assessments (Phase II 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 />c+v <br />• 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 />m personnel have performed hundreds of building inspections and have worked closely with <br />nn <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 />rs - <br />inspection, profile sampling, and characterization of chemical storage containers, such as <br />r, tanks, drums, and barrels <br />• Geophysical Investigations: Leighton will contract with GEOVislon 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 priorto invasive work, such as drilling and trenching. <br />M <br />CITY OF SANTA ANA I RIGHT OF WAY CONSULTING AND RELATED SERVICES ` 20 <br />h, <br />
