Yelm Planning Commission hears consultants’ climate-planning review; public questions data and costs

The Yelm Planning Commission held a public town-hall-style session on the city’s new climate planning element on Feb. 10, where Confluence Environmental consultants presented a climate vulnerability assessment and a community greenhouse gas inventory required under recent state changes to the Growth Management Act.

Consultant Phil Block, identified in the meeting as a senior biologist with Confluence, summarized the work: “There needs to be a climate component as well as a greenhouse gas inventory,” and outlined two reports posted on the city website — a climate vulnerability assessment and a greenhouse-gas inventory — that will inform draft policies. Mark Wolf, a project biologist at Confluence, said the vulnerability assessment examines assets and adaptive capacity across categories such as development and land use, buildings and transportation, utilities and water, ecosystems, human health and emergency management, and cultural resources.

The presentation described two main outputs: an assessment of how climate change could affect Yelm’s assets and services, and an inventory of greenhouse-gas emissions for the city/urban growth area (UGA). The inventory used the ClearPath tool and found residential energy was the largest source of emissions, with transportation and commercial energy also notable contributors. Presenters emphasized the inventory is a communitywide accounting (municipal, commercial and residential uses), not a consumption-based footprint for goods purchased elsewhere.

Commissioners and members of the public raised several technical and policy questions. Commissioners and residents asked whether the inventory counted electric and hybrid vehicles, how vehicle miles traveled (VMT) were estimated, and whether DMV registration data could give a more local count of electric vehicles. Confluence staff said they scaled Thurston County VMT down to Yelm by population and did not directly use a local EV registry; they agreed to explore DMV data and other approaches to improve local estimates.

Residents also questioned how natural gas and propane were treated in the inventory, noting many properties outside the city use propane. Confluence said some supply figures came from Puget Sound Energy and county-level sources and that parts of the dataset used estimates where meter-level data were not available. Commissioners and commenters repeatedly urged the consultants to flag places where estimates were used and to add context showing how commuting patterns (many residents travel outside Yelm for work) inflate local transportation emissions compared with larger, denser cities.

Several attendees pressed for economic context. Business owners warned that some possible policy measures — which the consultants described as a long “menu” of roughly 250 potential policy options collected from other jurisdictions — could impose significant upfront costs on small business and property owners (examples raised included building upgrades triggered by regulatory changes). Confluence staff said the long list is a brainstorming starting point and that the next steps will include screening that list, proposing a shorter set of candidate policies, and then seeking public feedback (including a planned survey) before any regulatory recommendations are drafted.

The consultants also discussed natural-features tradeoffs: state guidance often emphasizes urban tree canopy, but presenters and several residents noted Yelm’s historic prairie ecology and local priorities may call for different place-based solutions. Confluence said the vulnerability assessment documents ecosystem values and that policy choices about tree canopy, habitat protection and development siting will be up to the city.

Next steps described at the meeting: Confluence will work with city staff to pare the long policy list, post materials on the city website, circulate a public survey, and return with narrower options. Commissioners and members of the public asked for additional workshops and a possible joint working group with the City Council to focus on economic impacts and implementation feasibility before drafting final policy language.

The meeting record shows the consultants encouraged written comments and additional input; staff noted options for email and website comment submission during the public-review period. No formal commission adoption of climate policies occurred at this session; the presentations and public discussion will feed a later draft that the commission and council will consider.
