Project: Mascord Plan 1149C
11420 SW Fonner
Tigard, OR 97223
Project No: 160038
Subject: 6 Inch Thick Concrete Stem Wall In Lieu of 8 Inch Thick Wall -
Lateral Engineering
The project residence was originally designed with an eight inch thick concrete
stem wall. This one story structure may be constructed with a six inch thick stem
wall. The capacity of the holdowns specified on the plan installed in a six inch
thick stem wall are adequate to resist the uplift design loads.
Questions or comments regarding this letter are to be addressed to me.
