In response to your request, we have performed additional engineering
services on the subject project. These services included securing one
sample of subgrade soil for R-value testing. The R-value test was per-
formed by Testing Engineers-San Diego. Test results are attached. The
purpose of this work is to provide pavement recommendations on Hillside
Drive within the subject project. It is our understanding that Hillside
Drive should be classified as a collector (TI= 6.0).

Class III
Base (inches)

Prior to placing base materials, the subgrade should be scarified, moisture
conditioned and compacted to a minimum of 90 percent relative compac,tion.
The depth of compaction should be at least 6 inches.
Class III base should conform to section 400-23 of the "Standard Specifications
For Public Works Construction" (Green Book). Asphalt concrete should conform
to section 203-6 of the Green Book.
