Environmental Site Assessment

In the United States, an environmental site assessment is a report prepared for a real estate holding that identifies potential or existing environmental contamination liabilities. The analysis, often called an ESA, typically addresses both the underlying land as well as physical improvements to the property. Proposed and billed on a per-project, our investigations will serve the public and private sector markets. We follow current ASTM standard practice for Environmental Site Assessments. 

Threatened and Endangered Species

The Endangered Species Act (ESA) directs all Federal agencies to work to conserve endangered and threatened species. Under Section 7 of the ESA, Federal agencies must consult with the U.S. Fish and Wildlife Service when any action the agency carries out, funds, or authorizes (such as through a permit) may affect a listed endangered or threatened species. We draw upon our broad range of regional knowledge across the southwestern United States and experience with many regulatory agencies to provide biological assessments, habitat assessments, vegetation mapping and monitoring, and species surveys. 

Wetland/Waters of the U.S. Delineation

We provide wetlands/waters of the U.S. delineation following the USACE guidelines for permitting under Section 404 of the Clean Water Act. We provide documentation ranging from a simple determination to state whether wetlands and/or streams exist on a property, to the identification and marking of wetland and waters of the U.S. boundaries. In addition, we provide consultation whether a permit is required for work that may affect wetlands or streams. 

Regulatory Permitting

We can provide regulatory permitting and agency coordination - services may include preparation of agency coordination letters, pre-construction notification, or permit applications. Our experience includes work on a variety of projects related to the National Environmental Policy Act (NEPA), Rivers and Harbors Act (RHA), Clean Water Act (CWA), Endangered Species Act (ESA), Resource Conservation and Recovery Act (RCRA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), National Pollutant Discharge Elimination System (NPDES), and National Historic Preservation Act (NHPA) 

Water Resources

Our environmental services include water resources and planning services for stormwater and floodplain management compliance. In addition, we are experienced with USACE Section 404/10 permitting across the southwestern U.S. with staff including professional wetland scientists and ecologists trained in wetland/waters of the U.S. delineation, functional and conditional assessments, and wetland and stream mitigation plan preparation.

NEPA Environmental Documentation

We are highly experienced in preparing environmental documentation required by the National Environmental Policy Act (NEPA). Our professionals have completed environmental assessment (EA) and categorical exclusion (CE) documentation for a variety of federal projects including those for the U.S. Army Corps of Engineers (USACE), U.S. Bureau of Land Management (BLM), Federal Emergency Management Agency (FEMA), U.S. Forest Service (USFS), Federal Highway Administration (FHWA), Texas Department of Transportation (TXDOT).
