Storm records for Columbia County
Heavy snow accounts for 54 of Columbia County’s 69 storm reports, nearly four in five. High wind is a distant second at 8, ice storm has 3, and NOAA logged just one thunderstorm-wind and one hail report in the county between 2016 and 2026. Overall the county ranks 30th of 39 in Washington.
February is the month: 25 reports, more than December (15) and January (11) combined, and 78 percent of the record falls between November and February. Nothing was logged in July, August or September.
The last three years were quieter, 16 reports in 2023 through 2025 against 26 in 2020 through 2022, with 2021 the busiest year at 13. No deaths, no injuries and no property-damage dollar figure appear anywhere in the county’s NOAA record, which points to limbs and access, not structural damage, as the usual problem.

The county’s largest episode is a winter storm dated February 19, 2019 that dropped heavy snow on the northwest Blue Mountains and their foothills. NOAA put accumulations at 10 to 14 inches in the mountains and 3 to 6 inches in the foothills, with the deepest foothill totals near Dayton. Only 2 heavy snow reports came out of it for Columbia County, one for each zone, and no property damage was recorded, but that is the pattern for the whole record: a foot of snow at elevation and a few inches in town.

Hazard ratings
Strong wind: Very LowIce storm: Relatively LowWinter weather: Very LowWildfire: Relatively Low
FEMA’s National Risk Index (December 2025 release) rates Columbia County Very Low overall, with strong wind and winter weather both Very Low and ice storm and wildfire Relatively Low. The one number that stands out comes from the Forest Service, which puts wildfire risk to homes here above 66 percent of Washington counties.
For tree work the ratings and the storm record point the same way: planned winter pruning and removals, not emergency call-outs. Where the two disagree is fire. The storm table shows no wildfire reports, yet two thirds of the state’s counties carry lower wildfire risk to homes than this one, so keep dead conifers and ladder fuels away from the house on foothill lots and treat defensible space as the summer job.
Wildfire risk to homes: higher than 66% of Washington counties (USDA Forest Service, Wildfire Risk to Communities).

Burning the debris
Columbia County has no local clean air agency, so the Washington Department of Ecology’s statewide rules govern outdoor burning. WAC 173-425-040 bars residential and land-clearing burning inside urban growth areas and in cities over 10,000; Dayton, at 2,448 people, is well under that line, but the ban also applies inside any urban growth area, so check whether your lot sits in one. Everywhere else the limits in WAC 173-425-050 apply: no prohibited materials, someone in attendance the whole time, and a 50-foot setback.

Power lines and utilities

Cities and towns in Columbia County
Dayton is the only incorporated place on the list, with 2,448 of the county’s 4,141 people, and its tree rules have not been researched yet; ask city hall before touching a street tree. The rest of the county, 869 square miles of farmland and Blue Mountain foothills, lies outside any city limit, so no city permit applies there. Growth has been steady at 4.68 percent since 2020.

Labor index
BLS puts the mean wage for tree trimmers and pruners in Washington at $32.20 an hour (May 2025). No estimate is published for a county this small, so the statewide figure is shown, and it is a wage, not a price; bids are built per crew-hour and include the truck, chipper and travel, which matters here because crews may be driving in from outside the county.
The Census publishes no landscaping-services establishment count for Columbia County, which usually means too few firms to report without identifying them. Expect to call beyond the county line for a large removal.
Washington statewide: $32.20 per hour mean wage for tree trimmers and pruners (BLS, May 2025); no metro estimate is published, so the statewide figure is shown. This is a labor index, not a price; the modeled crew-hour cost used on this site is $210 (method).

Climate and growing conditions
USDA’s 2023 map puts most of Columbia County in hardiness zone 7a, with some ZIP codes in 7b. That is cold enough that replacement trees should be rated for 7a or hardier, and warm enough for the full range of dryland natives: ponderosa pine on the foothills, cottonwood and willow along the creeks.
Given 54 heavy snow reports, choose structure over speed. Trees with a single leader and well-spaced limbs carry February snow; fast-growing, multi-stemmed ornamentals split under it.

What to do next
Book the work for the dry months, which here means almost anything outside December through February, and have any leaning or dead tree assessed before the snow rather than after it. Compare bids with the modeled range on the cost page, allowing for travel if the crew is coming from outside the county, and check the company in the Washington license lookup before you pay a deposit.
