Resident urges wind monitoring and geologic review as Jefferson County discusses wildfire mitigation
Summary
At the May 20 Jefferson County commissioners meeting a resident urged wind monitoring, slope assessment and fuel removal at Beaver Ranch Park; commissioners and staff highlighted recent restoration work at Deer Creek Canyon and a June 3 community meeting on wildfire mitigation projects.
A Golden resident urged Jefferson County officials on May 20 to collect wind data, request slope assessments and remove leftover fuel piles at Beaver Ranch Park before vegetation removal proceeds.
Mike Rolick of Golden told the Board of County Commissioners that cutting trees on a ridgeline can increase wind throw and, if burning, accelerate wildfire spread. “When you cut the trees, we have ample research that shows you have more wind throw,” Rolick said, and suggested installing inexpensive anemometers to measure wind before and after any clear-cut work.
The request drew related updates from commissioners and county staff about recent and planned wildfire work in the county. Commissioner Zenzinger highlighted restoration and safety work at Deer Creek Canyon Park after the quarry fire, saying the reopening showed “there were zero losses of structures. There was nobody injured or hurt.” County staff and partners removed standing dead trees, assessed rock-fall hazards, dropped seed to stabilize soil and reopened the park far sooner than initially expected.
Why it matters: speakers said wind behavior on ridgelines and leftover fuel on the ground can change fire behavior and local erosion risk. Rolick told the board the specific ridgeline he inspected sits at about 8,400 feet and that slopes over 30 degrees may require assessment by the Colorado Geological Survey. He also noted visible piles of old cut wood at the site and suggested measuring winds near the ridgeline and at the park entrance (he referenced “South Fox Tim Road”) to compare conditions before and after any removal.
Details from the meeting:
- Public comment: Mike Rolick (18735 West 59 Drive, Golden) described a ridgeline above Castro Creek, provided coordinates on the record, and urged that the county or utility (he referenced CHEPCO in his remarks) place anemometers “to check the before and the after.” He described katabatic winds and likened local risk to the behavior seen in the Marshall Fire as an example of how wind-driven fire can spread.
- Technical and safety points: Rolick told commissioners that anything over a 30-degree slope can cause erosion and should be evaluated by the Colorado Geological Survey; he recommended preserving windbreaks along ridgelines, measuring wind changes with anemometers (he characterized the devices as “relatively inexpensive, just a, you know, a few $100 per anometer”), and starting mitigation by removing fuel piles from prior cuttings.
- County updates and context: Commissioner Zenzinger described attending the Deer Creek Canyon Park opening and summarized restoration work after the quarry fire; county staff said helicopters dropped roughly 10,000 pounds of native seed mix, crews removed standing dead trees along trails and assessed hazards. The county noted the fire scorched about 580 acres in parts of the park and that restoration work enabled an earlier-than-expected reopening (staff said the park was reopened within about 10 months though it had been projected to remain closed up to two years).
- Outreach and next steps: County Manager Joe Kirby and other commissioners said Jefferson County and partners will continue public outreach. The Conifer Fire Protection District is hosting a community meeting about 2025 wildfire mitigation projects — especially projects visible along the U.S. 285 corridor — on June 3 at 6:30 p.m. at West Jeff Middle School. County staff also referenced presentations and regional collaboration through the Northern Colorado collaborative and Jeffco Open Space on wildfire resiliency work.
No formal policy vote or directive on Beaver Ranch Park was taken at the hearing. The board received public comment, approved routine minutes and consent items (those votes were recorded separately), and closed the public-comment segment of the meeting.
The county’s next public-facing event related to the work discussed is the Conifer Fire District community meeting on June 3 at 6:30 p.m. at West Jeff Middle School, where attendees can hear project details and ask questions of the agencies involved.
