Thurston County planning commissioners review wetland protections as public raises mapping and cost concerns

Summary
At a work session, Thurston County staff reviewed Ecology’s three buffer options for wetlands protection. Public commenters warned of GeoData false positives and homeowner costs for biologist reports; staff highlighted tradeoffs between site-specific protections and staff capacity.
Thurston County planning commissioners spent a work session reviewing definitions, functions and possible protection strategies for wetlands, as staff outlined three Department of Ecology buffer options and answered commissioners’ questions about costs, maps and implementation.
A county staff member leading the presentation described the Ecology framework and three alternatives: Option 1, the most site-specific and flexible approach whose buffer widths are driven by habitat scores and can allow averaging and reductions tied to impact-minimization measures; Option 2, a middle-ground, use-specific table; and Option 3, a simple, rigid table recommended for jurisdictions with limited staff. "Option 1 is Ecology's preferred option," the staff member said, explaining it emphasizes habitat scores and site-specific assessments.
During public comment, resident John Pettit urged the commission to fix the county’s GeoData wetland layers, saying the map has "a lot of errors" and produces many false positives. Pettit read the site’s disclaimer aloud: "Thurston County and its officials and employees assume no responsibility or legal liability for the accuracy, completeness, reliability, timeliness, usefulness of any information on the site," and left printed comparisons between the county map and the National Wetlands Inventory.
Online commenter Loretta Zephanan asked staff to review a recent Growth Management Hearings Board decision in Snohomish County and how its findings might inform local wetland rules. Another commenter, Christie White, asked the commission to adopt Option 1 and suggested giving staff more calendar time to refine the critical areas ordinance.
Commissioners pressed staff on implementation tradeoffs: who pays for biologist reports, whether the permit section must first send county staff to verify mapped wetland triggers, and how to reduce unnecessary costs to homeowners. Commissioner Halverson asked, "Has there been any analysis done by the permit section on how much cost and hours would be required for each of these different options?" The staff member replied that specific numbers were not yet available and said the complexity and reporting requirements generally decrease from Option 1 to Option 3.
Several commissioners and members of the public pointed to the costs of requiring applicants to hire private wetland biologists. One commissioner noted that county code currently says the director of CPED should send a staff member to verify whether a wetland exists before a homeowner must hire a biologist; several speakers said that verification step is not consistently being done. The presenter cautioned that using county staff for every site visit is "borderline impossible" with current staffing levels and proposed clarifying code language and administrative procedures so responsibilities, qualifications for professionals, and reporting standards are explicit.
Staff described other reforms under consideration: improving the GeoData map viewer and data sources (including more recent NRCS hydric-soil data and the National Wetlands Inventory), adding clearer special-report standards into the chapter so applicants know what is required, and using administrative procedure manuals to make implementation more consistent. Staff also noted the county recently added a definition of "qualified professional" to the code to reduce disputes over whether a consultant meets county standards.
Next steps: staff and commissioners agreed to continue the wetlands conversation at future meetings, including follow-ups on Habitat Conservation Plan interactions, fish and wildlife habitat areas and prairie habitats. The planning commission did not adopt new code during this session; commissioners asked staff to develop clearer report standards, explore map and staffing options, and return with materials to inform a choice among the Ecology options. The meeting ended with a brief staff update on an open streamflow restoration planner position and routine calendar checks.
