About this file

Written by GovTribe AI · Oct 27, 2026

This document is a Tree Removal and Protection Plan for the Denney Road Capital Project, prepared by Harper Houf Peterson Righellis Inc. for Washington County's Land Use & Transportation Department in Oregon. The project encompasses the roadway from Southwest 105th Avenue to Southwest Scholls Ferry Road and requires the removal of 41 total trees located in the right-of-way. The engineering plans detail tree locations, protection zones, and removal specifications across multiple plan sheets (TR-1 through TR-5), with right-of-way acquisition expected to be completed by December 15, 2026, and all tree removal work must be completed by January 15, 2027. The plans include construction notes specifying hand tool installation methods within tree protection zones, stump removal using only stump grinding, and coordination requirements with Portland General Electric for guy wire installation.

The plan identifies specific trees by parcel number and address along the project corridor, designating certain trees for removal while establishing drip line plus 5-foot tree protection fencing for trees to be protected during construction. Construction notes require crown pruning on specified trees and temporary fence opening procedures for concrete demolition work within protection zones, with coordination required with the project arborist for alternative methods. Additional tree data sheets (TR-6 through TR-8) provide detailed specifications for each tree marked for removal, including tree types and conditions, with references to a separate arborist report for mitigation details. No pricing information, set-asides, or contract award details are contained in this preliminary engineering document.

SEE NOTES BELOW

1. WITHIN TREE PROTECTION ZONE, PERMANENT FENCE CONSTRUCTION SHALL BE BY HAND

AND WITH HAND TOLLS ONLY. ADJUST FENCE POSTS TO AVOID TREE ROOT IMPACTS.

2. FOR DEMO OF EXISTING CONCRETE WITHIN THE TREE PROTECTION FENCING,

TEMPORARILY OPEN THE TREE PROTECTION FENCING, USE A SMALL RUBBER TRACKED

MACHINE OPERATING ALONG THE EXISTING SIDEWALK TO CAREFULLY REMOVE AND HAUL

PANELS OUTSIDE THE TREE PROTECTION ZONE. THEN CLOSE THE TREE PROTECTION

FENCE. COORDINATE WITH THE PROJECT ARBORIST FOR ALTERNATIVE METHODS.
