Commission approves Labra Lane six‑lot concept with conditions to reduce wildlife and slope impacts
Summary
The commission approved a six‑lot concept plan for Labra Lane Aug. 12 but required additional work: a clearer slope/topographic analysis, fire‑access input from the fire marshal, incorporation of the Wildlife Habitat Analysis into revised envelopes (particularly lots 5 and 6), and a mitigation plan (2:1 area‑based) where impacts cannot be avoided.
TETON COUNTY, Idaho — A six‑lot concept plan for Labra Lane, on roughly 85 acres in the valley’s southwest, won conditional approval Aug. 12 after county staff and wildlife consultants raised concerns about steep slopes, access, habitat fragmentation and long‑term wildfire risk.
County staff said the parcel lies within multiple environmental overlays — big‑game migration corridors, seasonal range, a wildfire hazard overlay and a bear‑conflict overlay — and that the site’s steep slopes and drainage patterns constrain where homes and roads can be built. Joshua (county planning) and consultants noted the submitted building envelopes attempted to avoid the steepest slopes but that several envelopes, and the proposed road alignment, intersected areas mapped as high‑value wildlife habitat.
Kent Warland, senior ecologist for Biota Research, told commissioners the property is “super challenging to develop” from a wildlife perspective and that high wildlife value is dispersed across the parcel. “The least impactful approach would be to cluster as much as possible,” Warland said, and he described a mitigation approach that combines on‑site thinning and restoration with additional area‑based mitigation to meet the county’s 2:1 mitigation standard.
Neighbors raised doubts about access, water supply for required fire protection and potential effects on springs and private water rights. Heather Taylor Allen, representing a neighboring ranch, said the drainage is swampy in places, questioned whether wells could support required fire‑suppression systems and warned of likely county costs if the adjacent public road were later widened.
The applicant, Nelson Engineering, and the landowner said they had explored multiple layouts and that they are willing to revise the plan to reduce habitat fragmentation and to remove one southern lot if necessary to shorten road length and reduce disturbance. Planner and commissioners agreed preliminary work — a higher‑resolution slope/topographic survey, demonstration that proposed building envelopes can meet the 30% slope limit, an NP evaluation and additional input from the fire marshal — should be required prior to preliminary plat.
The commission approved the concept with staff’s recommended conditions and two additional requirements: (1) further input and information from the fire marshal regarding layout and fire access in the wildfire hazard overlay; and (2) incorporation of the WHA findings to adjust lot layouts and building envelopes (with specific attention to lots 5 and 6) to reduce fragmentation of indicator habitat. The applicant suggested alternatives, including consolidating the southern lots into a single larger parcel to reduce road length and habitat impact.
Next steps: applicant to provide refined slope/topography mapping, a geotechnical/NP evaluation where required, a refined building‑envelope plan influenced by the WHA, and a mitigation plan that satisfies the county’s area‑based requirements before preliminary plat review.
