LEChas prepared environmental assessments and impact statements in accordance with NEPA and related acts. Projects include:
new transportation facilities
water line construction
street and highway construction projects
new federal facilities and
major residential developments
These assessment/impact statements included evaluating the following issues:Land Use — The evaluation of local, regional, and state land development plans and trends to determine conformity between the proposed project and the current and proposed land use.Social and Economic — The evaluation of direct and indirect impacts to individuals and communities to prevent disproportionate impacts based on race, color, ethnicity, wealth or status.Relocation — The statistical analysis and comparison of the numbers and characteristics of individuals, neighborhoods, and communities to be relocated within an area.Air Quality — Mobile air emissions modeling for microscale emissions concerns including one (1) and eight (8) hour carbon monoxide predictions and conformity to National Ambient Air Quality Standards.Noise Analysis — The evaluation of traffic generated noise through noise meter data collection modeling using Federal Highway Administration Highway Traffic Noise Prediction Model Version 2.5, and evaluating the effectiveness of noise abatement procedures.Water Quality — The identification and analysis of the effects of non-point source pollution on streams, reservoirs, wellheads, groundwater recharge areas and other water bodies considered to be sensitive water resources.Wetlands — The identification of wetlands based on type, quality and function and the assessment and mitigation of proposed impacts based on U.S. Army Corps of Engineers standard operating procedures.Other Waters of the U.S. — The analysis of streams based on chemical, biological, and physical characteristics including the identification of 303d streams, trout streams, and other sensitive waters. Also, the location of waterbody modifications and the resulting impacts to those modifications are assessed.Floodplain Impacts — The identification of flood risks within a corridor, the impacts of a project on natural and beneficial floodplains, and the measures needed to minimize floodplain impacts.Threatened and Endangered Species — Coordination with Federal and State agencies on the identification of threatened, endangered, and sensitive species and/or critical habitat potentially located within a project area as regulated under the Endangered Species Act. If these areas are present, measures to avoid or minimize impacts can be assessed under direct consultation with the U.S. Fish and Wildlife Service or the National Marine Fisheries Service.Historical and Archeological Structures — Coordination with State Historic Preservation Officers, Federally recognized Native American Tribes, and the National Park Service on the identification of Section 106 and Section 4f resources.Hazardous Waste Sites — All sites regulated under the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) are identified and evaluated. If sites are located within a project area, then avoidance, removal, or remediation alternatives are assessed.
