Jessi has applied her expertise to projects that include sediment remedial design evaluation and cap modeling, environmental and civil engineering design, water quality monitoring, remedial investigations and feasibility studies, the assembly of conceptual and design-level cost estimates, and agency negotiations and permitting. She is a proven project manager for complex upland and in-water remediation projects that involve effective management of large teams of contractors and experts, multi-year complex budget management, and multiple agency negotiations. Jessi is also experienced with environmental chemistry and related microbial processes, water quality, and chemical analyses, using a wide array of laboratory analytical tools and methods.

Jessi is experienced in upland and sediment field data collection, data analysis, and interpretation. Jessi has applied this experience to a number of sediment and upland-based habitat restoration, environmental contamination, source control, and cleanup and construction projects. Jessi has served as project manager on numerous sediment investigations in freshwater and marine locations in Washington and Oregon. In this role, she has planned and implemented the investigations, prepared and reviewed specifications for permitting and design, reported the results, and assisted clients in negotiating the outcomes with Washington State Department of Ecology, Oregon Department of Environmental Quality, U.S. Environmental Protection Agency, and various Trustee groups. Her sediment work has also included negotiating complicated multi-objective sampling programs and development of dredging, sampling, and monitoring plans. Jessi has an exceptionally strong reputation and close working relationship with federal, state, and local agencies in negotiating permit requirements, as well.
