Tetra Tech has prepared more than 500 site-specific, programmatic, and legislative Environmental Assessments and Environmental Impact Statements (EAs/EISs) and other supporting studies for a wide variety of Department of Defense (DoD) actions, including Army Transformation, base closure, base operations, weapons acquisition and fielding, construction (e.g., ranges, housing), special land use permits for expanded training, land withdrawls, and real estate leasing and transfer. These documents range from fast-track EAs for ongoing mission activities to EISs for large-scale training missions and weapon system deployments. We're currently leading preparation of NEPA compliance documents for the Army Transformation Program, including a strategic environmental assessment, nationwide Programmatic EIS, and site-specific EISs. Support to Army Transformation is the Corps's highest priority military program. In addition, we're leading preparation of NEPA and Environmental Baseline Surveys (EBSs) for the Residential Community Initiative (RCI) throughout the nation. We also led preparation of more than 40 EAs/EISs for the Army Base Realignment and Closure (BRAC) Program. Tetra Tech personnel have been instrumental in assisting DoD in preparing guidance to facilitate and standardize NEPA analysis and documentation for Army programs. For example, we prepared the Army's BRAC Manual for Compliance with NEPA, Army National Guard NEPA Manual, Army NEPA Compliance Manual for Installation Operations and Training, NEPA Manual for Off-Post Training and Deployments, and NEPA Manual for Residential Community Initiatives. For more than 20 years Tetra Tech has provided turnkey services in civil and water resources planning and engineering to the Corps's Civil Works Program. To date, our team of scientists and engineers have served the Civil Works mission in 18 Corps Districts. We've successfully completed more than 2,500 environmental projects under the Civil Works Program. Civil Works projects include ecological restoration reports under Sections 206 and 1135, lake and shoreline management, dredging studies, water allocation studies, section 404 permitting actions, risk-based and economic flood damage analysis, socioeconomic studies, recreational capacity studies, lock and dam studies, fish passage and habitat studies, and supporting cultural resource studies.

For example, we conducted more than 40 flora/fauna surveys, management plans, and T&E surveys for the Army Materiel Command (AMC) in support of 17 installations nationwide. We've prepared numerous management planning products for Corps clients, including Integrated Natural Resource Management Plans (INRMPs), Endangered Species Management Plans (ESMPs), and Biological Assessments.
