GDI Project: Polygon-1 13-05 Prepared By: Zane Rogers
Project Name ,,._._.. Roshak Ridge 6/16/2022
Location: SW Bull Mountain Road and SW Roy Report#: 228
Rogers Road, Tigard
Arrival: 930 Departure: 1000
Weather: Cloudy, 50's Permit#: TBA
Site Visit Requested By: Sam (Taylor Morrison) Met With (on site): f Sam; Chuck (KeyWest)
Purpose: Observe Lot 206 Wall
Outstanding Issues: , fR 227(0G1022) Lot 20G needs more analysis regarding its stability RESOLVED
Upon arrival I observed KeyWest had completed wall reconstruction adjacent to Lot 206. We previously
recommended that since lock and load walls were in close proximity to proposed foundation walls, two
consecutive geogrids (consecutive vertical blocks) should be placed behind walls and under foundations. I was
informed KeyWest removed blocks, grids, and backfill for a portion of the wall (approximately 1-6 blocks) and
reconstructed the wall in the area of the proposed residence.
I observed KeyWest pothole with a shovel to expose grids in the sidewalls and observed that two geogrids
were indeed present under areas where building foundations will be constructed. Geogrid lengths appeared to
have been cut to design length or slightly longer. Crushed rock backfill appeared adequately compacted
behind the lock and load wall.
Based on observations and conversations with KeyWest personnel, it is our opinion that lock and load wall
reconstruction in the vicinity of lot 206 observed today has been prepared in general accordance with our
geotechnical recommendations
