I would recommend pruning the dockshed from the tree. Maybe minor reduction of the lateral spread but not by much. Maybe 5%.That wee truck is parked alongside it for scale. Road is single lane… Guessing crown spread ~70’, ~28” but spread matters more.
I'm open to suggestions, what are your thoughts and bid? The client is having a new pier put in for $$$, the tree is touching the dock shed, bank is getting undercut beneath the tree from erosion etc etc
The new pier should be done end of Jan and will make for easier brush clean up (still not easy tho). Bucket could setup there, we only climb.
I’d look at thinning to stimulate interior growth as this tree is critical to the shore stability. The erosion would be significant worse if the tree wasn’t there.
Now if the undercut is significant enough to destabilize the tree and it did fail to the water this would actually naturally stabilize the bank. And mitigate further erosion. But likely not allowed due to the pier.
Maybe they should have the pier folks bring in a log or three and anchor them down with duckbills or chains to dampen any wave action and see if a few boulders above the high water mark could help? (Bulkheads and rock shore armoring actually contribute to erosion creating eddies on either end, scouring these and even hooking around the armorment thus worsening).
Now if this is a last ditch effort to keep the tree standing due to slope creep, or boarder line active failure super heavy boarder line topping can reduce leverage loads. BUT normal 10-15% reductions can increase the load on the root plate in high wind loads. You loose mass dampening so the wind is more akin to the big bad wolf. Or think of sky scrapers where movement is designed into the structure, accounting for wind loads and earthquakes.
I can’t tell if that is a bay or a river, maybe schedule for low tide and use the beach as a drop zone and bundle the brush and using a more favorable angle winch loads back up using the same tree as a gin. Attach a tagline to swing higher on the bank or the road itself.
Many times on jobs like this I will refuse to give a straight fixed price. I’ll do a hourly rate which is higher than my daily target hourly rate due to the complexities and sensitivity of the critical area, but an estimate of hours I think it will take. Most of the time I’m actually pretty close.
From my armchair and imagination I’d put around 2k-3.5k, but could be as low as 1k.
But this is assuming a 70’ crown spread and 28” dbh and about 60-70’ tall.
