CARLSBAD OAKS NORTH LOT 1
CARLSBAD, CALIFORNIA
Dear Ms. Daugherty:
In accordance with your request, we have prepared this correspondence provide our opinion regarding
the feasibility of creating a senior living facility on Lot 1 of the Carlsbad Oaks North Business Park in
Carlsbad, California. For the purpose of this letter, we have reviewed the preliminary development
plan entitled Oakmont of Carlsbad, Carlsbad, California, Site Plan, prepared by Landesign Group,
dated February 2017, and our reports entitled Report of Testing and Observation Services During Site
Grading, Carlsbad Oaks North Business Park, Phase 1, Lots 1 through 9, Carlsbad, California, dated
October 30, 2006 and Addendum to Report of Testing and Observation Services During Site Grading,
Carlsbad Oaks North Business Park, Phase 1, Lot 1, Carlsbad, California, dated October 30, 2008.
Lot I of the Carlsbad Oaks North Business Park consists of an easterly sloping sheet graded pad that
was created in 2006 during the overall mass grading of Carlsbad Oaks North Phase 1. The lot was
originally left low and subsequently completed in 2008. The as-graded condition consists of
compacted fill underlain by the Point Loma Formation. The center portion of the pad was undercut to
eliminate cut-fill transitions that resulted from the mass grading. Fill thicknesses across the pad range
from approximately 2 to 20 feet. The surface soils have a "low" to "medium" expansion potential and
a "moderate" to "severe" sulfate exposure rating.
The referenced plan indicates that development will consist of fine grading the site to support a three-
story luxury assisted living facility, a two-story memory care building and a one-story models
building. A pool, parking areas and associated infrastructure is also proposed. Although the referenced
plan is preliminary, we anticipate that cuts and fills on the order of five feet or less will be necessary to
achieve the final building pad configuration.
Based on our review, and the information above, it is our opinion that the proposed senior living
facility is feasible from a geotechnical perspective. A future update geotechnical report considering the
ultimate development plan should be, prepared once civil grading plans are developed. The report
would provide specific geotechnical recommendations pertinent to the design and construction of the
project.
