Re: Addition to residence at 11985 SW Mominghill Dr. in Tigard, OR
Dear Mr. Green:
We have examined the proposed 5' x 17' second -floor, bathroom addition over the existing single -
story portion of the referenced residence. The approximate total load on the existing 6" thick
foundation wall and 6' x12" wide footing, including the new addition, will be less than 1000 lb /ft on
the 17' long foundation and less than 500 lb /ft on the two return foundations. These loads are far less
than the Code - accepted 1500 lb /sf and will be structurally satisfactory. The minor nature of the
proposed addition will not significantly increase the lateral loads on the building and the existing
foundation will accommodate the anticipated, design lateral loads.
If you have questions about any of this information or conditions that we have not addressed, please
call our office.
