P1B20 Worklist, Map and Notes
The objective of this work is to reduce the risk of tree failures on to a busy roadway, but leave stumps
and root wads in place to continue help stabilize the soil. This work will entail the removal of
approximately 130 tree stems to low stumps along the north side of Route 169 – the Maple Valley
Highway, opposite the Riviera Apartments. A constant and substantial amount of traffic control will be
required, along with bucket trucks and chippers. One lane of westbound traffic will need to be closed
during operations. A crane might need to be used to facilitate the removal of 2 tall cottonwood trees
at the western-most end of the work zone. At 22” and 24” inches DBH respectively, these are the only
trees currently logged in the inventory database. The bulk of the trees are Big Leaf Maples with a
handful of Alders and smaller cottonwoods. These have not been measured, but range in diameter
from a few inches to twenty inches. All debris will need to hauled or chipped. A sequence of photos is
included below showing which trees are to be removed. The total number is approximate and reflects
the number of stems as opposed to individual trees. On steeper banks the stumps may be left at 4-5’
feet if access is difficult. Chips can be dumped across the other side of the river next to the dog park.
