Routt County holds wide‑ranging work session on wildlife mitigation; partners urge plan before in‑lieu fees

Routt County planners convened wildlife experts, local conservation groups and commissioners April 28 for a work session aimed at turning the county’s high‑priority habitat mapping into a practical mitigation framework for developers and county reviewers.

Colorado Parks and Wildlife land‑use specialist Molly (on the record as a CPW land‑use specialist) told commissioners that CPW’s high‑priority habitat (HPH) layers — a subset of its species activity mapping (SAM) — are designed to be the county’s trigger for additional mitigation requirements in the county’s Unified Development Code (UDC). Molly said CPW is increasingly open to using pooled mitigation funds or mitigation banks for larger‑scale conservation projects rather than many small, piecemeal conservation actions.

"It allows us to take a step back and collect funds until we get enough funds to do something meaningful," Molly said, describing the advantages of funds or banks over single small projects.

Why it matters: Routt County’s updated UDC requires avoidance, minimization and, where unavoidable, mitigation for developments that affect HPH. Commissioners and staff said material increases in subdivision, PUD and solar applications make it urgent to define both the science and the process that will determine when a project must provide compensatory mitigation and what mitigation is acceptable.

Conservation and science partners — including Drew Rayburn, director of science for The Nature Conservancy in Colorado; Tim Sullivan, senior director of climate resilience for the Yampa Valley Sustainability Council; and Megan Knott, director of stewardship for Colorado Cattlemen’s Agricultural Land Trust — urged a locally driven conservation plan that sets quantitative targets, aligns priorities and identifies projects where mitigation funds would produce the biggest landscape‑scale gains.

"The ability to have more funding for restoration projects, particularly on existing conserved land, I think is a really good strategy," Sullivan said, noting recent state data showing the Upper Yampa basin as high‑value for restoration potential.

Presenters also flagged several technical choices commissioners will need to make: whether to accept compensatory mitigation as an in‑lieu fee, whether to require like‑for‑like mitigation in the immediate watershed, how to value habitat loss for mixed species, and whether the county should use its 10‑41 powers to designate conservation areas. Several speakers urged staff to avoid creating a mechanism that simply accumulates small, uncoordinated projects. "Random acts of conservation" — small, disconnected mitigation projects — will not produce the scale of benefit experts say is needed, one speaker said.

Staff next steps: Planning staff said they will continue to work with CPW, Earth Economics (which has advised the county), The Nature Conservancy, the Yampa Valley Sustainability Council and local land‑trust partners to draft clearer guidance for applicants. That guidance would include (a) which mapping layers will trigger review; (b) how applicants should engage CPW early in the process; (c) draft valuation approaches to support compensatory mitigation; and (d) options for holding and administering mitigation funds, including use of a third‑party fiscal sponsor, a mitigation bank, or CPW‑hosted grant processes.

No regulatory change yet: Commissioners did not adopt any new rule at the meeting. They signaled chief priorities: a science‑backed prioritization (stacking biodiversity, recreation and cultural values), a locally driven mitigation plan, and concrete project examples that show how mitigation funds would be used to conserve or restore habitat in perpetuity.

What’s next: Staff will return with a memo outlining options and costs for (1) producing a Routt County conservation strategy and (2) building a defensible valuation method for compensatory mitigation should the board choose to authorize an in‑lieu fee or bank model.
