Chris’s natural science expertise has been applied to a wide variety of projects including transportation, residential, commercial, forestry, river engineering, and habitat restoration. He has a keen understanding of how to analyze impacts on the landscape from various land uses and construction methods, and how to develop appropriate mitigation measures. Chris’s diverse experience has allowed him to refine his skills in communicating with a broad audience in both verbal and written forms. He possesses a superb ability to communicate technical information to lay audiences, technical experts, stakeholder groups, and regulatory authorities alike.

Examples of Chris’s project work include the following:

  • As the Endangered Species Act, Permitting, and Mitigation Task Lead, Chris has been an instrumental team member through the NEPA, ESA, and mitigation planning for the I-5 to Medina portion of the State Route 520 Bridge Replacement and HOV Program for the Washington State Department of Transportation (WSDOT). Chris played a key role on a multidisciplinary team to facilitate the ESA consultation and permitting process. Chris continues to be a valued advisor on the full spectrum of natural resource, mitigation, and environmental regulatory compliance issues on current portions of the SR 520 program.
  • Under Confluence on-call contracts, Chris has conducted work for numerous task orders ranging from field investigations to permitting assistance to third-party review. For Snohomish County, where he worked as Senior Environmental Planner prior to joining Confluence, Chris assisted with fish exclusion activities for two mitigation projects, and provided technical support on a project to determine applicable U.S. Army Corps of Engineers regulatory requirements for 17 proposed culvert replacements. For the City of Stanwood, Chris has completed a variety of projects, including critical areas third-party reviews for proposed developments, and a large wetland delineation for property the city intends to develop into a park.
  • Chris has supported ESA compliance for projects by authoring biological assessments and analyzing Essential Fish Habitat necessary for ESA consultation. This work includes conducting field investigations, analyzing effects of project construction on ESA-listed species, and identifying avoidance and minimization measures.


“Chris’s knowledge of wetland functions and his attention to detail played a key role in the successful permitting of our project.”
