Consulting and specifications

[evo]

I just walked from a project for many reasons.

I’d like some feedback with limited discription of what’s going on. This project involves many large trees and utility trenches.
ICRZ is defined as x6 trunk diameter or 1” DBH=6” radial. CRZ is the basic x12 diameters or 1”DBH = 12”
Many of the trees will have a 3-12’ deep ditch between the trunk and ICRZ with no budget.

Lots of trees? How will they (or you) know where every root is coming from? So they cut too many roots, stop progress and call the arborist to wait for an assessment before moving? What are the assessment options??? Keep digging? Stop and relocate the trench? Remove the tree?

Is boring and option? "No budget" sounds like it should be.

All good questions. The report mentioned switching to hydro vac or air excavation, but due to lack of budget trees are simply being condemned the real issue is two fold.
1) can the city reasonably provide mitigation to preserve the ROW trees.
2) infringement on private trees whose roots extended into the ROW.

If tact doesn’t change soon, I’d expect 40% tree loss across the project which includes 55” cedars and 40” doug firs.

What's it cost to remove a 55" cedar? I gotta think that's more than a horizontal bore. Plus, you get to keep the tree. Short-sighted thinking. Sounds like a city.

I think depth of the lines, and pipe diameter makes boring less cost effective, but agree. Did I mention this is a landslide prone uplands area? Deep sandy gravely soils 10+’ to an impervious silty clay layer that causes the water to squirt out of the side of the bluff.
It would be one thing if they tied in all the impervious surfaces (French drains and roof runoff) in the the storm water system. Unfortunately not though it’s only capturing road runoff that doesn’t infiltrate in the ditch.

If your job is to consult the project to avoid excess root damage, would you essentially end up blocking the whole project due to the constraints of options? The stick in the mud as it were (literally, sort of).

That would increase the budget and timeline but that’s city work for ya isn’t it?

Or do they have the power to ignore your recommendations and just destroy the tree?

I’m very curious about this because I was very close to working on a city sidewalk reno big myself, managing construction around street trees. The firm didn’t get the bid which is maybe all for the best. I think it would be hard to be a true lover of trees and work on these kinds of projects, you’d have to be pretty cutthroat.
