Re: Williams-Golis Deck Replacement
PAE #16015
To Whom It may Concern:
As part of the work associated with the proposed deck replacement projects, a boulder
landscape wall is planned to be constructed near the southwest corner of the house, up to
about seven feet in height. Attached is a stamped drawing depicting an engineering
design guideline for a spherical boulder wall. Angular boulders generally provide
greater stability that spherical boulders, depending on the manner in which they are
"nested" by the builder, nonetheless, the size of various courses of boulders can be
approximated by the design guideline based on overall wall height.
Please contact me if you have and questions regarding this matter.
Sincerely,
ti, .... .11
