Project Name: Polygon at Bull Mountain (River Terrace SF) Attached: CT-03.1
Subject: Concrete Stem Wall Height
Drawings Affected:
Description/Action:
This bulletin provides response to RFI, design clarifications and/or variation requests for the
'Polygon at Bull Mountain (River Terrace SF)' project located in Tigard, Oregon.
It's our understanding that there are some site conditions which require the concrete stem wall to
exceed 4'-0" in height. This is an acceptable revision for stem walls up to 8'-0" in height provided
the differential height between exterior finish grade and the soil elevation in the crawlspace does not
exceed 2'-0" as shown in the attached detail. Note that either finish grade or crawlspace soil
elevation may be at a higher elevation as long as the differential height between the two is not
greater than 2'-0".
