Dear Mr. Schwarz:
In accordance with the request of Mr. Andrew Gracey, we prepared this addendum to the geotechnical
investigation for the subject project to provide an updated project description and geologic map based
on the lasted grading plan (Reference 3).
Reference 2 indicated wall heights up to 40 feet. Based on the latest plans, walls with heights up to
48-feet are planned. The recommendations contained in Reference 1 and 2 remain applicable for the
planned wall heights up to 48 feet.
Figure 1 provides an updated geologic map for the project based on Reference 3. Based on our review
of the grading plan, the geotechnical recommendations contained in References 1 and 2 remain
applicable.
If you have any questions regarding this letter, or if we may be of further service, please contact the
undersigned at your convenience.
Very truly yours,
