Natural Resources
& Ecology

LJA Environmental Services has vast experience with Natural Resources. Proposed actions often require additional coordination and approval of the U.S. Coast Guard, Texas Parks and Wildlife Department, U.S. Fish and Wildlife Service, Texas General Land Office, Environmental Protection Agency, Texas Commission on Environmental Quality, and National Marine Fisheries Service. We have designed and/or built over 2,500 acres of wetland habitat, including several wetland mitigation banks. Compensatory mitigation systems are often required as part of USACE/COE permits; and where applicable, our professionals design these systems. Mitigation systems require a unique understanding of the Natural Environment and our professionals routinely design systems in harmony with the Texas environment. Our professionals are recognized leaders in providing assessments for wetlands and Jurisdictional Waters of the United States. They excel at the permitting services required by Sections 401 and 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act. All delineations of Jurisdictional Waters of the United States are performed in accordance with the 1987 USACE/COE Wetland Delineation Manual.
