PROPOSAL FOR On -Call Environmental Services RFP NO.. 21 105 team can provide standard Feld survey capabilities and special status species expertise that can be applied to terrestrial plants and animals, wetlands areas, and avian species considerations. Cultural Resources Study/Historical Resources Assessment. The Tetra Tech Team includes experienced cultural resource managers with training in Anthropology and Archaeology, and experience in community outreach, including outreach to Native American Tribes. Tetra Tech's archaeologists and architectural historians have the national and regional expertise and experience to perform literature and record reviews, conduct pedestrian and intensive surveys to identify and evaluate historic and prehistoric properties. Our cultural resources staff exceed the Secretary of the Interior's Standard Qualifications for History, Architectural History, and Archaeology, allowing us to provide archaeological and historic architectural studies and reporting. Tetra Tech staff have also conducted site evaluations and, nominations and monitoring following California Register of Historical Resources and National Register of Historic Places criteria and guidelines. Tetra Tech has extensive experience working with the California State Historic Preservation Office, conducting Tribal consultation, and experience with Section 106 of the National Historic Preservation Act in conjunction with CEQA. Hazards/Hazardous Materials/Environmental Site Assessments. A Phase I Environmental Site Assessment (ESA) is a "due diligence" process, which identifies hazardous and potentially hazardous conditions in and/or adjacent to the site. ESAs consist of record reviews and property research activities and may include sampling of building materials. ESAs provide important information regarding property value, liability issues, and redevelopment constraints. If recognized environmental conditions or known environmental impairments are identified, a Phase II ESA may be conducted to determine the potential nature and extent of contamination. Our ESAs consistently meet or exceed current American Standard Test Method standards, agency requirements, and client expectations. Our services include: Phase I and II ESAs, Resource Conservation and Recovery Act/Comprehensive Environmental Response, Compensation, and Liability Act investigations, underground storage tank investigations, sediment/water quality analysis, hazardous materials/hazardous waste assessment, health risk assessment, impact assessments, soil and groundwater sampling, pilot testing and full-scale remediation. Geology/Soils/Minerals Studies. Evaluating the possibility that a project could create unstable conditions, or that the location of a project could elevate specific hazardous conditions for the completed development (particularly if structures are involved) are among the effects considered by a geologic evaluation. Local topography, proposed project grading, soil compaction requirements, and erosion potential all must be considered to evaluate how a project might impact local geology and soils. The availability of mineral resources in the project area must be determined to evaluate how a project might impact access to these resources. Proximity to fault zones, areas with high liquefaction potential, and the prevalence of expansive soils (containing certain clay types) all affect the potential that the local geology and soils could exacerbate hazards for a project. Tetra Tech geologists and engineers are expert in evaluating and describing these local conditions and can evaluate the ways in which geology, soils and mineral resources could impact, or be impacted by, a project. Tetra Tech has broad experience with geotechnical projects ranging from geotechnical investigation and materials testing to foundation design. Hydrology/Water Quality Study. Water issues are of paramount consideration in southern California, and CEQA assessment requires that both water quality and water supply (particularly relative to groundwater) issues are evaluated. Tetra Tech is a leader in water analysis from an engineering perspective and from an environmental perspective. We have experts in water supply engineering (including groundwater extraction and water infrastructure design) and environmental evaluations. Tetra Tech can provide technical studies to evaluate and provide clear and concise assessments of any aspect of potential environmental effects from almost any imaginable project. Noise Impact Study. Tetra Tech can evaluate and calculate noise and vibration levels expected during the construction and operation phases of a project. Construction noise impact evaluations consider the City of Santa Ana 17 TETRA TECH
