In accordance with your request, we have prepared this letter summarizing the as-graded
geotechnical conditions of building pads, Lots 12 through 14 for La Costa Ridge residential
development. The site was previously graded under the observation and testing services of
Geocon, as documented in the referenced report above. The final grading for the subject building
pads has been completed, however, utility earthwork and street grading operations for the
remainder of the site are ongoing as of the date of this letter. Based on observations made during
the site visit on December 6, 2005, the condition of the building pads appear to have been graded
in accordance with currently accepted standards and are suitable to receive the proposed
improvements.
