There are two ways to remove a tree. Felling it whole is fast and clean, and it needs a clear lane longer than the tree is tall with a margin on both sides. Few Beaverton backyards have that. So most of our removals are sectional: a climber takes the tree apart from the top down, and every piece that could hit something is lowered on a rope.
Rigging
The rope runs through a block set high in the tree and down to a friction device at the base, so one person on the ground can lower a limb that weighs as much as a motorcycle and stop it a foot above your roof. When the tree itself is too decayed to rig from, we rig from a neighboring tree, or we take smaller pieces.
Protecting the yard
Mats and plywood go down where wood lands and where the crew walks. Irrigation heads, landscape lighting and anything else you point out gets flagged. Fence panels can be taken out and put back when that is the safer route for the wood.
Trees near wires
The insulated line running from the pole to your house can be dropped for the day by Portland General Electric, and we schedule that with them. The bare high-voltage lines along the street are different. If a tree is in those, PGE's line-clearance crews make it safe before we touch it.
Permits: check before you book
Inside the city, removing a street tree always takes a permit, and the permit normally requires a replacement from the city's approved list. Most ordinary backyard trees need none. Trees in significant groves, natural resource areas and approved landscape plans are protected, and so are designated significant and historic trees. In unincorporated Aloha, Cedar Mill, Bethany and Cedar Hills the city's rules don't apply and the county's do.
We check the tree's status before the job goes on the calendar. The permit checker gives you a first answer in two questions, and the permit guide has the detail.
