Eric analyzes environmental impacts on fish and other aquatic organisms in freshwater, estuarine, and marine environments, with an emphasis on habitat protection and restoration strategies. He also is an environmental regulatory compliance specialist, with expertise in Endangered Species Act (ESA) Section 7 compliance, the National Environmental Policy Act (NEPA), and the Marine Mammal Protection Act (MMPA). Eric has worked closely with agencies such as the National Marine Fisheries Service (NMFS), U.S. Fish and Wildlife Service (USFWS), and U.S. Army Corps of Engineers (Corps) to develop regional guidance and complete complex individual and programmatic consultations. In his 20+ years of environmental consulting, Eric has authored numerous technical and regulatory compliance documents for projects in the areas of restoration, transportation, fish passage, and land use. His clients range from local, state, and federal agencies to tribes and nonprofit organizations. In addition, he has substantial fieldwork experience in salmonid habitat surveys; biological monitoring; and marine biological surveys in intertidal, open water, and benthic environments.

Examples of Eric’s project work include the following:

  • Eric is leading the integration of salmonid life-cycle models with long-term habitat status and trends monitoring to support ESA-listed salmon conservation and recovery efforts in the Columbia River Basin for tribal governments in the United States and Canada.
  • Eric provided ESA compliance expertise to the Corps Seattle District Regulatory Division to develop the biological assessment and NMFS/USFWS biological opinion for a programmatic ESA consultation covering fish passage and habitat restoration actions in Washington State. The documents were developed to streamline the permitting and ESA consultation process for environmentally beneficial fish passage and restoration projects.
  • For the City of Bellevue, Washington, Eric provided biological expertise on an integrated team to develop a comprehensive solution to chronic sediment deposition and flooding problems on a hydromodified reach of urban Sunset Creek. The solution involved the development of an innovative culvert design that included an integrated sediment trap along with channel enhancements to improve habitat conditions, fish passage, and sediment transport.
  • Eric led development of the fisheries and aquatic habitat component of a NEPA environmental impact statement (EIS) for the Tongue River Railroad, a proposed spur line connecting new coal mines in the Powder River Basin in southeast Montana to the Burlington Northern rail network in southern Montana. He led a field team in remote environments to characterize aquatic habitat conditions in the Tongue River and tributary streams over a 150-mile study corridor. Eric compiled this survey information into a habitat characterization for 53 different fish species known or likely to occur in the study area, and developed the direct, indirect and cumulative impact analysis components of the NEPA EIS.
