NEPA, Environmental Planning and Permitting

AEC provides a range of environmental planning and permitting services, including National Environmental Policy Act (NEPA) and State Environmental Policy Act (SEPA) compliance. We complete all aspects of data collection, research, field surveys, team management and agency coordination for these documents. Our documents are legally sound, present practical mitigation measures, and integrate permitting requirements, such as those for wetlands and endangered species.

Our experience includes developing the following:

  • NEPA
  • Categorical Exclusion (CE)
  • Environmental Assessment (EA)/Finding of No Significant Impact (FONSI)
  • Environmental Impact Statement (EIS) process and Record of Decision (ROD)
  • SEPA
  • Critical Areas Ordinance and Shoreline Compliance, Habitat Management Plans, Shoreline Impact Assessments
  • Mitigation Planning
  • Joint Applications and Joint Aquatic Resource Project Approvals (JARPA) to obtain 404, 401, HPAs, and Stream Alteration Permits

Wetland Studies

AEC conducts wetland delineations, wetland functional assessments, mitigation, restoration, and permitting in Washington, Idaho, and Montana. We are experts applying the U.S. Army Corps of Engineers Wetland Delineation Manual including the Western Mountains, Valleys, and Coasts and Arid West regional supplements, and other supplements. For functional assessments, we routinely use the Montana Wetland Functional Assessment and the Eastern and Western Washington Wetland Rating Systems. We assess wetland impacts, develop mitigation plans and complete permitting for section 404 and 401 of the Clean Water Act, and state and local permits.

Biological Studies

AEC conducts Biological Assessments (BA) in compliance with Section 7 of the ESA of 1973 and also prepares Habitat Management Plans, Shoreline Impact Assessments, and other reports to analyze impacts to critical areas under the Growth Management Act. This involves agency coordination, field studies, mapping, impact assessment, and preparing reports that meet regulatory requirements. AEC also conducts rare plant surveys, weed surveys, avian surveys, and other biological support as necessary.
