Environmental Planning and Compliance

DEA’s natural resources services help clients define and manage water and environmental resources through such services as:

  • Evaluating aquatic, terrestrial, and wetland habitats, and performing wetland delineations, ecological surveys, and functional assessments
  • Designing and implementing effective regulatory strategies and compliance monitoring, mitigation planning and development, and site-sensitive habitat restoration
  • Planning and creating systems resiliency to reduce the impacts of climate change
  • Evaluating water supply scenarios
  • Facilitating water dispute resolutions
Environmental Planning and Documentation

Successfully balancing social, economic, and environmental interests is challenging for applicants, regulatory agencies, citizens, and decision makers. We work in partnership with project stakeholders to identify and resolve environmental issues and create a sustainable future for people, plants, and wildlife.


  • Biological studies, including assessments and evaluations for sensitive, threatened, and endangered species
  • Coastal resource plans
  • Erosion control plans
  • Fisheries studies
  • Forest Service special use permits
  • Mitigation and monitoring plans
  • National Pollutant Discharge Elimination System (NPDES) permits
  • NEPA/SEPA/CEQA documents, including Environmental Assessments (EAs), Environmental Impact Statements (EISs), and Environmental Impact Reports (EIRs)
  • Resource agency consultation
  • Shoreline and coastal zone management
  • Stormwater pollution control plans

Endangered Species Act/Clean Water Act Compliance

Environmental protection laws, such as the National Environmental Policy Act and the Endangered Species Act, provide a framework for technical studies, impact assessments, and public involvement programs. Our environmental planners and scientists help clients anticipate potential environmental impacts as well as permit procedures and requirements. We have developed an approach to conducting environmental analyses that leads to successfully facilitating compliance with federal, state, and local regulations.


  • Biological assessments
  • Conservation plans
  • NPDES permitting
  • Section 404 wetlands permitting
  • Stormwater management
  • Total Maximum Daily Load (TMDL) compliance and water quality modeling
