REGULATORY COMPLIANCE All fills, removals and processing of original ground under the purview of this report have been completed under the observation and with selective testing by Petra, and are found to be in compliance with the grading code of the County of Riverside and the City of Temecula, California, The completed work has been reviewed and is considered adequate for the construction now planned, On the basis of our findings, the following recommendations were prepared in conformance with generally accepted professional engineering practices and no further warranty is implied or made, SUMMARY OF GRADING OPERATIONS I. The purpose of the grading operation was to develop a 15:t-foot-wide, primarily level-graded access road to accommodate construction of an 8-inch-diameter sewer line through the site, as shown on the accompanying geotechnical maps (in pockets) \ I I I I I I I I I I I I I I I I I I I CCL CONSTRUCTION, INC. Sewer Line Backfill/ Tracts 23100-4 & 23101-3 February 7, 1997 J.N. 474-96 Page 2 2. Earthwork operations were conducted in essentially three phases, The first phase consisted of the rough-grading of a 15:t-foot-wide access road through the site to the general configuration shown on the accompanying grading plans, This area was left approximately 2 feet below the final grades during this phase of grading, The second phase included construction of the sewer line and testing of the backfill soils on a full-time basis, The third phase consisted of completing the placement of the final 2 feet of fill soils, subgrade compaction and placement of 4 inches of base over the entire alignment, Additionally, the fill slopes were trimmed back to achieve the design grades, 3, Grading of the entire alignment began on November I, 1996, and was completed on February 6, 1997, Rough grading was conducted by WA Guthridge ofY orba Linda, California, and the sewer line was constructed by Southern California Pipeline of Tustin, California, 4, An existing active 24-inch reclaimed water line was encountered just southeast of the intersection ofParducci Lane and Promenade Chardonnay Hills. The actual location of this water line, where it encroached into the sewer-line alignment, was from Stations 54+00 to 54+70, as indicated on the sewer and water plans, Removal of alluvial soils was conducted to within approximately 10 feet of this line based on the locations identified by Underground Service Alert in the field, Porous alluvial soils were observed underlying this water line, but were not removed due to the potential for damaging the line, The approximate location of the 24-inch water transmission line and limits of alluvial removals are shown on the accompanying geotechnical maps, ENGINEERING GEOLOGY General Geologic conditions exposed during the process of grading were frequently observed by our geologic staff, A California Certified Engineering Geologist observed and approved all removal bottoms prior to fill placement. Geolol!:ic Units Bedrock materials exposed within the cut areas of the streets and slopes consist of the Pauba Formation bedrock (map symbol Qps), This material consists of massive to crudely bedded silty sand which is medium dense to dense, ~ ~ ~ I I I I I I I I I I I I I I I I I I I CCL CONSTRUCTION, INe.

Proper slope maintenance should be provided to mitigate excessive erosion to the slopes, SOILS ENGINEERING Preparation of Existinl!: Ground I. All weeds, grasses and similar organic materials were stripped and removed from the site prior to grading, 2. All loose, excessively wet and compressible topsoil, slopewash, alluvial and colluvial materials were removed to competent material prior to placing fill, Removal depths varied from 2 to 12 feet and were conducted to the toe-of-slope, as shown on the accompanying geotechnical maps. 3, Areas to receive fill were scarified and bladed to a depth of 6 to 8 inches, watered and mixed, as required, to achieve optimum moisture conditions, and were compacted to a minimum relative compaction of90 percent of the maximum dry density as determined by ASTM D1557-91. 4, T oe-of-fill slope keys having a minimum width of 15 feet were placed at the base of all fill slopes, Fill keys were excavated into competent native material with a minimum slope of 2 percent to the heel of the key, Temporary Fill Slone Construction Temporary fill slopes ranged from 2 to 20 feet high at a 2:1 (H:V) gradient, were overfilled and backrolled every 4 to 5 feet with a sheepsfoot roller pulled by a rubber- tired dozer. Slopes were track-walked with the dozer and then trimmed back to the ~ . ~ I I I I I I I I I I I I I I I I I I I CCL CONSTRUCTION, INC.

Laboratorv Testinl!: The laboratory maximum dry density and optimum moisture content for each major soil type were determined in accordance with ASTM Test Method D1557-91.

Fill consisted of onsite materials having the above-mentioned soil classifications, Fill materials were placed in lifts restricted to 6 inches in thickness, watered, as required, to achieve optimum moisture conditions and were compacted to a minimum relative compaction of 90 percent of the maximum dry density as determined by ASTM Dl557-91. 2. Maximum depth offill is approximately 26 feet. 3, Fill placed on surface having a slope gradient steeper than 5: 1 (H: V) were keyed and benched into compacted materials or dense native soils, Field Testinl! I. Field density tests were performed using the nuclear gauge method (ASTM D2922-91) and the sand cone method (ASTM DI556-82), Test results are shown in Table II (attached), The approximate locations of the field density tests are shown on the accompanying geotechnical maps, 2, Field density tests were taken at sufficient intervals to determine that adequate compaction was being achieve, Where tests indicated inadequate compaction, the areas were reworked and retested, 3. Visual classification of earth materials in the field was the basis for determining which maximum density value to employ for a given density test, Frequent one- point checks were performed to supplement visual classifications. ~ ~ ~ I I I I I I I I I I I I I I I I I I I I CCL CONSTRUCTION, INC.

Tracts 23100-4 & 23101-3 February 7, 1997 IN. 474-96 Page 6 UTILITY TRENCHES Onsite soils generally consisted of silty sands and required mechanical effort to achieve proper compaction, All backfill for the sewer line was compacted to a minimum relative compaction of 90 percent ofthe maximum dry density as determined by ASTM Dl557-91. CONCLUSIONS AND RECOMMENDATIONS All fill soils tested ultimately met the minimum relative compaction requirement of 90 percent of the maximum dry density as determined by ASTM D1557-91. Since all slopes constructed during this phase of grading are considered temporary, it is our understanding that slope landscaping will not be provided, Due to the potential for erosion on fill slopes and cut slopes derived from the Pauba Formation, rain water should not be allowed to overtop slopes, Minor settlement may occur along the alignment between Stations 54+00 and 54+70 where porous alluvial soils were left in-place under the existing 24-inch water transmission line, This potential settlement is not expected to adversely impact the sewer line which was constructed in competent soils approximately 4 feet below the existing water line, During future phases of grading, this existing water transmission line may need to be relocated, At this time, the alluvial soils left in-place below and within approximately 10 feet of this pipe should be removed and replaced with compacted fill soils. Additional Considerations The project soils engineer shall be notified prior to fill placement regarding the site or backfilling of trenches after rough grading has been completed, Additionally, Petra should be notified to conduct footing excavation observation under slab-trench '" ~ ~ I I I I I I I I I I I I I I I I I I I eeL CONSTRUCTION, lNe.
