Wetland Delineation and Permitting

Wetlands function as natural water quality treatment areas, flood zone buffers, and provide important habitat for plants, fish and wildlife, including rare and endangered species. Hollaway Environmental + Communications Services provides valuable perspective on site suitability by delineating and surveying wetland areas in the field, evaluating soil conditions, assessing potential permit requirements, and identifying possible regulatory concerns.

Wetland Delineation and Permitting

Our wetland and natural resource professionals have vast experience successfully completing Clean Water Act (CWA) permitting, as well as wetland delineations and stream and waterbody assessments. We conduct hundreds of miles of wetland delineations and stream assessments each year, and we are grateful to be known as “the best in the business.”

Our highly qualified wildlife biologists are experienced in performing on-site natural resource studies and preparing technical reports required by local, state and federal jurisdictions for sensitive species as well as threatened and endangered species.
