The subject project is located in the city of Lake Elsinore, Riverside County, California. Rough grading for the subject lots has been completed under the observation of, and with selective testing by, GeoTek, Inc. (GeoTek) during the period from January 19 through March 2, 2021. It is to the best of our knowledge that site grading has been completed in general accordance with the approved geotechnical reports (see references) for the site, applicable provisions of the 2019 California Building Code (CBC) and City of Lake Elsinore guidelines. This report provides a summary of site conditions observed during earthwork construction, results of field density and moisture content test results, as well as finalized foundation design recommendations. GEOTECHNICAL I ENVIRONMENTAL I MATERIALS KB Home March I6, 2021 Lots I through 10 and 12 through 33, Tract No. 30698 Project No. 2467-CR City of Lake Elsinore, Riverside County, California Page 2 SUMMARY OF GEOLOGIC AND SOILS CONDITIONS Based on our field observations and testing during site grading, we note the following: ■ Significant visible vegetation and deleterious materials were removed within the limits of the earthwork construction and disposed of off-site. ■ The overall site area, beneath the existing engineered fill, is generally underlain by bedrock materials of the Bedford Canyon Formation. ■ The approximate limits of grading under the purview of this report are shown on the enclosed Density Test Location Maps (Plates I and 2). The Density Test Location Maps use Sheets 4 and 8 of I I of the 40-scale project Rough Grading Plan as a base. The grading plan was prepared by Hunsaker & Associates and modified by Mayers and Associates and is dated February 6, 2006. ■ Removal bottoms exposed competent bedrock materials as recommended in the referenced report (GeoTek, 2020). Removal bottoms were scarified, moisture conditioned and compacted prior to placement of engineered fill materials. ■ Fill materials consisting of on-site soils were placed in thin lifts, approximately six to eight inches thick, brought to at least optimum moisture content and compacted. If initial testing indicated less than 90 percent relative compaction and/or less than optimum moisture content, the contractor was notified. The area was re-processed, and/or compacted, and/or moisture conditioned until a minimum relative compaction of 90 percent and/or optimum moisture content was achieved. ■ Fill placement for the project generally followed the recommendations provided in the approved project geotechnical report with respect to fill keyways, benching and other typical hillside grading techniques. ■ All cut lots (i.e. Lots 10 and 12 through 29) were overexcavated a minimum depth of three feet below proposed grade and then scarified and moisture conditioned another 12-inches prior to placement of engineered fill. ■ The cut portion of all transition lots (i.e. Lots 6 through 9 and 30) were overexcavated a minimum depth of three feet below finish grade, or to a depth of 1/3 the maximum fill thickness, whichever was greater, and then scarified and moisture conditioned another 12-inches prior to placement of engineered fill.

The field density testing for the subject lots was performed using a nuclear gauge, in general accordance with testing procedure ASTM D 6938. The results of the field density tests are included in the attached Table I. The approximate locations of the field density tests are shown on the enclosed Density Test Location Maps (Plates I and 2).

Results of the testing indicated a soluble sulfate content which is considered "not applicable" (i.e. negligible) per Table 4.2.1 of ACI 318 for the subject lots. Based on these results, no special concrete mix design is required by Code to resist sulfate attack. Test results are presented in the table below. Lot Nos.

Additionally, an increase of one-third may be applied when considering short-term live loads (e.g. seismic and wind loads). POST GRADING CRITERIA Additional Grading/Construction Observations We recommend that foundation plans be reviewed by this office prior to construction to check for conformance with the recommendations of this report. We also recommend that GeoTek representatives be present during site development and foundation construction to check for proper implementation of the geotechnical recommendations. The client's representatives should verify that GeoTek perform at least the following duties: ■ Observe and perform compaction tests on utility line trench backfill within the property boundaries. ■ Observe and perform moisture content evaluation tests on the subgrade soil prior to pouring concrete slabs and other flatwork. ■ Observe and probe foundation excavations to confirm suitability of materials with respect to density. GEOTEK KB Home March I6, 2021 Lots I through 10 and 12 through 33, Tract No. 30698 Project No. 2467-CR City of Lake Elsinore, Riverside County, California Page 7 Drainage Positive site drainage should be maintained at all times. Water should be directed away from foundations and not be allowed to pond or seep into the ground immediately adjacent to footings. Pad drainage should be directed toward approved areas. Foundation Observation All footing excavations should be observed by a representative of this office to check for compliance with the recommendations prior to the placement of reinforcement. It would likely be necessary to perform this observation following compaction of the interior utility trenches. REGULATORY COMPLIANCE Our recommendations are based on the site conditions observed and encountered, and laboratory testing. Our conclusions and recommendations are professional opinions that are limited to the extent of the available data. Cuts, fills and processing of original ground under the purview of this report, have been completed under the observation of, and with selective testing by GeoTek, Inc. and are found to be in compliance with the Grading Ordinances of the City of Lake Elsinore, California. Our findings were made, and recommendations prepared in conformance with generally accepted professional engineering practices and no further warranty is implied. This report is subject to review by the controlling authorities for this project. GeoTek accepts neither responsibility nor liability for work, testing, or recommendations performed or provided by others.
