L&G Environmental division is committed to providing high quality, cost effective environmental services including, but not limited to, National Environmental Policy Act (NEPA) compliance, purpose and need development, fatal flaw reports, development of project alternatives, indirect and cumulative effects analysis, public involvement, public comment content analysis, cultural and historical resource management, agency coordination, noise analysis, and the preparation of PCE, CE, EA, and other NEPA documents. This also includes the assessment of air quality impacts, Section 4(F) properties, vegetation impacts, threatened and endangered species surveys, water quality impacts, floodplain and farmland impacts, and the facilitation of relocations.

L&G also provides a full service environmental science and engineering firm that serves both the public and private sector to find solutions to environmental issues. These services include storm water pollution prevention plans, wetland delineations, wetland permitting, Phase I and II site assessments including groundwater monitoring, underground storage tank removal, and waste management oversight.

The L&G staff is experienced and knowledgeable in NEPA compliance, Council of Environmental Quality (CEQ) Regulations, 23 CFR Part 771, as well as the requirements of the US Army Corps of Engineers (USACE), which include the federal objectives for water and related land resources planning established in the Economic and Environmental Principles for Water and Related Lane Resources Implementation Studies (Principles) and the Economic and Environmental Guidelines for Water and Related Land Resources Implementation Studies (Guidelines), and the USACE procedures for environmental evaluation outlined in Appendix C of the USACE Planning Guidance Notebook. 

The L&G environmental mapping division is at the forefront of environmental constraints mapping. This service allows for the identification of environmentally problematic areas where project development should be restricted. Design limitations such as floodplains, soil types, wildlife habitat, watershed concerns, hazardous materials sites, archeological and historical sites, and public facilities such as parks, schools, and churches are clearly identified on an environmental constraints map. This becomes a valuable tool, that in coordination with the engineering division, allows for the design of projects that facilitate the human and natural environment throughout the design phase and also serves to reduce mitigation costs as the project goes to construction.
