Tree removal in Sammamish, Washington

Permit rules for removing a tree in Sammamish

Sammamish uses two thresholds: a conifer 8 inches DBH or larger, or a deciduous tree 12 inches or larger, is significant, and removing one needs a permit from the Community Development Permit Center (425-295-0531). What sets the city apart is the annual cap in SMC 21.03.060, tied to lot size.

On a lot under 1/4 acre you may remove 2 significant trees a year and 6 in ten years. A 1/4 to 1/2 acre lot allows 4 a year (12 per decade); 1/2 to 1 acre, 6 (18); 1 to 2 acres, 8 (24); and over 2 acres, 10 (30). Count what you have taken in the past decade before you plan a multi-tree job, because the ten-year total can bind before the yearly one does.

Trees in the street right-of-way need a Type B Right-of-Way permit. No fee or contractor registration was found.

What tree removal costs in Sammamish

Crew-hours drive the modeled range below, priced against the Seattle-Tacoma-Bellevue labor index: BLS reports a $33.85 mean hourly wage for tree trimmers and pruners in the metro. It is a wage, not a price; the methodology explains the conversion.

The cap shapes cost here in a way it does not elsewhere. If you can only take 2 trees this year, mobilization is spread over fewer stems, so the per-tree figure tends toward the upper end. Conifers above 8 inches on a wooded lot also mean taller rigging work, which moves the job down the table.

Modeled estimate, not quotes (method): crew-hours × $210 per crew-hour; ×1.25 within 10 ft of a structure, ×1.3 with no truck access; a crane day adds $1,500–$3,500; stump grinding is separate.

Storm records for King County

King County’s storm count has dropped sharply in recent years. NOAA logged 32 reports in the last three years against 54 in the three before, a fall of about 40%. Over the full record since 2016 there are 133, ranking the county 16 of 39 in Washington.

Fewer reports do not mean milder storms. The worst single episode, the east-wind event of November 2024, falls inside the quieter period. Heavy snow still leads the record at 68 reports, and 84% of all reports come between November and February, so a tree weakened by one winter tends to go in the next.

How removals are done here

Sammamish lots tend to carry tall conifers, and the permit threshold for them, 8 inches DBH, is low enough that most yard firs and cedars qualify. Removal is usually a climb-and-rig job, with the crown lowered in pieces and the trunk felled once the drop zone is clear; where it is not, see crane removal.

Winter weight is the main stressor. FEMA’s National Risk Index scores King County 94.7 for winter weather and 91.1 for ice, and a conifer that lost its top or split under snow is a common reason homeowners use part of their annual allowance. A dead tree still needs checking against the permit rules.

What to do next

Before booking a crew, check three things: whether the tree is a conifer of 8 inches DBH or a deciduous tree of 12, how many significant trees you have removed this year and in the past ten, and whether the trunk is in the right-of-way. The Permit Center at 425-295-0531 can confirm your lot-size bracket.

Then vet the contractor through the Washington license lookup, and if you are unsure whether a tree needs to come down, start with a risk assessment. Neighboring Issaquah, 3 miles away, measures significance differently.
