Tree Service in West Minnehaha, WA

This pocket between Hazel Dell Avenue and St Johns Road filled in after the war, house by house, across ground that had been farmed and planted long before anyone platted it. That history is still standing in the back yards: Douglas fir and bigleaf maple far older than the roofs beside them, black walnut, and the odd surviving apple or filbert in a fence line where a row used to run.

Every Generation of Building Worked Around These Trees

Deep lots get divided here. A shop goes up, a second dwelling goes in at the back, a driveway is cut down the side to reach it, a trench goes through for water and power. Each of those is a reasonable thing to do with your property, and each one happens inside the root plate of a tree that has been there ninety years. The crown does not object at the time. That is the whole difficulty with it.

The Damage Shows Up Three Years After the Excavator Leaves

A conifer that loses a quarter of its anchoring roots to a footing trench will usually leaf out fine that same summer and the one after. The decline comes slowly — shorter growth at the tips, small pale needles, deadwood working down from the top. Compaction does the same thing from the other direction, when tracked machines and stacked material squeeze the air out of the soil the fine roots were living in. By the time the crown looks wrong, the roots have been gone for years, and the failure that follows is not a limb. It is the whole tree tipping out of ground it no longer holds.

• Growth at the branch tips getting shorter each year while the tree looks green from the street
• Dieback starting at the very top of a conifer rather than in the lower canopy
• Fresh soil, gravel or paving laid over what used to be lawn under the dripline
• A trunk that has started to lean since the work, or cracked ground on the uphill side of the base
• Bracket fungi coming out of the root collar in autumn, often on the side that got cut

Which Old Trees Are Worth Keeping Through a Build

Not all of them, and we will say which. A sound fir well clear of the new footprint is worth real trouble to protect — nothing you plant replaces that shade in your lifetime. A leaning maple with a compromised base sitting where the driveway has to go is better removed before the build than after, while there is still access for a truck and no new siding to work over. Removing it later costs more and risks more. That is a blunt conversation, and it belongs at the start of the project rather than at the end.
