Environmental Services

Quadrant's experienced staff includes environmental scientists who understand both public works projects and the environment, and know how to make clients' projects environmentally friendly while achieving their goals. We have substantial experience in preparing categorical exclusions (CE); environmental assessments (EA), and environmental impact statements (EIS) for transit, roadway and aviation design projects. We also do noise and air quality modeling, wetland and vegetation assessment, and socioeconomic studies.
