In accordance with your request, we have prepared this letter summarizing the as-graded
geotechnical conditions of Phase 10 building pads, Lots 11 and 15 through 20 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.
