Project: Polygon-126-08 Prepared By: 11Sam Freeman
Project Name: South River Terrace - Phase 2 Date: 112/06/22
Location: SW Bull Mountain Road and SW Roy Report#: I 141
Rogers Road, Tigard
Arrival: 0830 Departure: ; 0915
Weather: Overcast, 30's Permit#:
Site Visit Requested By: j Rich (Taylor Morrison) Met With (on site): Rich (Taylor Morrison)
Purpose: Observe Subgrade
Outstanding Issues: j FR141 (12/5/22) - Soft and saturated surface muck, lots 102-109 subgrade
I observed crews prepared subgrade for lots 100-109 (see site plan). At the time of my site visit the subgrade in each
lot was covered in 2-6"of crushed rock, which appeared to be 1 'A"with generally little fines content. In lots 100 and
101 this rock section appeared generally dense and well-keyed, but in lots 102-109 the rock section appeared
generally rough and not compacted.Where exposed on the edges and sidewalls of the excavation, I observed
subgrade to consist generally of brown silt to silty gravel. I used a%a" diameter steel foundation probe to evaluate
the relative density of the subgrade through the base rock. Resistance to penetration indicated generally stiff/
dense conditions, but several inches of soft disturbed soil in some of the lots. In lots 102 and 103 I used white spray
paint to indicate the areas where soft subgrade was observed, while in lots 104-109 the thin (-1-3"), soft muck
appeared ubiquitous throughout each entire lot. I informed Rich (Taylor Morrison)that we recommend removal of
standing water and soft surface muck prior to footing and slab construction, as well as compaction of the base rock
until dense and well-keyed.
Based on observations and probing, it is our opinion that the lot subgrade observed today as indicated on the
attached site plan has been prepared in general accordance with our geotechnical recommendations, except for soft
areas indicated above.
