Dear Ms. Tyler:
In accordance with your request, SCST, Inc. reviewed the referenced improvements plans for the
rear, yard of the subject property. Our referenced report reviewed the existing conditions and
recommended a properly designed and constructed retaining wall configuration similar to that
existing would provide a slope stability condition considered similar or more favorable than the 2013
as-graded slope. In our opinion, the plans are prepared in accordance with the recommendation of
our referenced geotechnical report and, as designed, are the minimum necessary improvements to
stabilize the slope. If segmental reinforced earth walls are selected, the backfill should consist of
granular fill screened of rocks over approximately 1 inch in dimension. The construction should
include observations and density testing by the geotechnical representative. If you have any
questions, please call us at (619) 280-4321.
Respectfully submitted,
SCST, INC. 0
