County rolls out evacuation modeling and PerimeterMap tools; Smart911 and livestock evacuation flagged as priorities
Summary
County staff outlined a worst‑case evacuation modeling program using SimTable, CNA and PerimeterMap to build internal evacuation zones; Smart911 messaging for vulnerable residents and livestock‑evacuation gaps (raised after the Davis fire) were identified as follow‑up items.
A county evacuation study representative told the Warm Springs CAB that the county has launched a website to collect public input and has contracted vendors to run worst‑case fire and traffic models. The representative said modeling (SimTable via TMCC for fire/weather and CNA for analysis) will help planners map internal evacuation zones and test responses to high‑risk scenarios.
PerimeterMap will host the county's internal evacuation zones and automatically feed in road closures, the speaker said, allowing incident commanders to avoid cutting lines through properties during an evacuation. The speaker emphasized the public site is for input only; the internal PerimeterMap zones are for emergency managers and incident staff.
The meeting highlighted outreach to residents with access and functional needs through Smart911, which can send tailored instructions and request extra evacuation time. Residents raised a separate but related concern: livestock evacuation. One attendee described the Davis fire experience where veterinarians and horse owners were denied access and animals were released in the road. The study lead said the county has asked the Nevada Office of Emergency Management to examine neighbor‑assistance or Colorado‑style volunteer trailer networks and to include livestock evacuation planning in the study.
Why it matters: the modeling and PerimeterMap deployment aim to make evacuation orders more precise and reduce dangerous access problems, especially where events or population surges (rallies, festivals) change normal traffic patterns. The county encouraged CAB members to drop street‑level concerns on the study website and said it will return with simulation results.
Next steps: staff will run models by CAB area, post example videos for local review when possible, and pursue solutions for livestock evacuation and neighbor‑responder coordination through state emergency management.
