Gentlemen: In accordance with your request, we have reviewed the founda- tion recommendation section of our report entitled "Final Report of Engineering Observation of Grading and Testing of Compacted Fill, Lake Calavera Hills, Unit No. 1, Lots 2 through 141, Carlsbad Tract No. 76-12, Carlsbad, California," dated April 28, 1981. We recommend in our report that footings be founded at least 12 inches below finish grade. It is our opinion that the footings may be placed 10 inches below rough as compacted grade providing at least 2 inches of soil is placed against the footing during the fine lot grading. If you have any questions, please call. Very truly yours, Richard P. While R.E. 21992 RPW/SAW/eej Consuhng Engreers.

SUMMARY OF GENERAL EARTHWORK AND TESTING Site preparation, compaction, and testing were done between January 7 and April 3, 1981. In our opinion, based on our observation and testing, the work performed during that period was in general conformance with the Specifications for Con- trolled Fill attached to our report entitled "Update Geo- technical Investigation for The Proposed Lake Calavera Hills Tract76-12, Carlsbad, California," dated January 20, 1981. - .,- -- During the grading period, fill was placed, compacted, and tested on fill and cut-fill Lots 2 through 6, 8 through 12, 14 through 34, 40 through 46, 50, 52 through 63, 69 through 78, 81 through 92, 95 through 98, 101, 105 through 111, 118 through 120, and 122 through 139. Lot 140 remains as an ungraded open space lot and Lot 141, a future school site, was used as a borrow and stockpile area. mini park, Lot 1, designated as a has not been finish graded and will be reported when grading is complete. .- - - _- Grading of the site essentially consisted of excavating loose surface and alluvial soils, installing subdrains in the can- yens , preparing areas to receive fill and making cuts and fills to design grade. An existing 14-inch watermain located along Glasgow Drive was removed and the void filled with com- pacted soil. During the grading operation, compaction procedures were ob- served, and field density tests were made to help evaluate the relative compaction of the placed fill. Field observations and results of field density tests indicate that the fill has been generally compacted to 90 percent or more of maximum dry laboratory density as determined in accordance with ASTM Test Method No. D1557-70. For reference! the approximate location of field density tests and the limits of compacted fill have been recorded on a copy of the grading plan. The results of field density tests, expressed as a percent of maximum labor- atory dry density (relative compaction), are given on the attached forms. Laboratory tests were made on representative samples of the materials used for fill. The tests were per- formed to evaluate moisture density relationships, maximum dry density, optimum moisture content, grain size distribution, and plasticity, strength, and swell characteristics. The results of laboratory tests are attached. -. ” ** ‘ ;. ., Pacific Scene I . ; April 29, 1981 4 Project No. 502161-FCOl Wb .iward-Clyde Consultants - Page 3 SUMMARY OF FINISH GRADE SOIL CONDITIONS During the grading operation, certain treated to provide a specified depth of grade. lots were specially select soil at rough - Fill Lots and Fill Portion of Cut-Fill Lots - - Inspection and laboratory tests indicate that nonexpansive fill was placed within 2 feet of rough grade on all fill lots and the fill portion of cut-fill lots noted herein. Cut Lots and Cut Portion of Cut-Fill Lots - On Lots 2 through 6, 8 through 12, 14, 15, 17 through 29, 40 through 46, 50, 53 through 63, 70 through 78, 81 through 84, 92, 95 through 98, 101, 105 through 111, 118 through 120, and 122 through 134, expansive soil was excavated and replaced with nonexpansive fill to a depth of 2 feet below rough lot grade over the entire level lot or along daylight line where expansive soils were encountered. The recommendations pre- sented herein are not intended for structures or appurtenances located beyond the limits of the undercut. Cut Lots Not Undercut Cut Lots 7, 13, 35 through 39, 47 through 49, 51, 64 through 68, 79, 80, 93, 94, 99, 100, 102 through 104, 112 through 117 and 121 were inspected at the completion of grading. The inspection indicated that no expansive soil is evident at rough grade surface. RECOMMENDATIONS Foundations for Structures on Nonexpansive Soils - - We recommend that foundations for single- or two-story (resi- dential) structures placed on nonexpansive, undisturbed soil or on nonexpansive, properly compacted fill be designed for a i bearing pressure not exceeding 2000 psf (dead plus live , loads). We recommend that footings be founded at least 12 inches below finished grade, and have a minimum width of 12 inches. In our opinion, this bearing pressure can be in- creased by no more than one-third for loads that include wind or seismic forces. -. ... Pacific Scene I,. April 29, 1981 ‘( Project No. 502161-FCOl - Page 4 Wq IwardXlyde Consultants - Slopes Fill slopes at the site have inclinations varying from approx- imately 2 to 1 to l-1/2 to 1 (horizontal to vertical), and are approximately 60 feet high. Fill slopes were treated by peri- odically backrolling with a sheepsfoot compactor and track rolled. We recommend that structures that will not tolerate differential settlements (such as foundations, swimming pools, concrete decks, walls, etc.) not be located within 8 feet of the top of a slope. We recommend that footings that are lo- cated within 8 feet of the top of a slope be extended in depth until the outer bottom edge of the footing is 8 feet hori- zontally from the outside face of the slope. - -- - - Additional Fill and Utility Trenches This report discusses the fill placement observed by personnel from our firm during the period specified. We recommend that any additional fill placed, as well as backfill placed in utility trenches located within 5 feet of a building and deeper than 12 inches, or backfill placed in any trench lo- cated 5 feet or more from a building and deeper than 5 feet, be compacted under our observation and tested to verify com- pliance with the earthwork specifications for the project. We should be contacted at least 24 hours prior to backfilling operations. - .- - .~.. - Drainaqe We recommend that positive measures be taken to properly finish grade each lot (after structures and other improvements are in place), so that drainage waters from the lot and ad- jacent properties are directed off the lot and away from foundations, floor slabs, and slope tops. Even when these measures are taken, a shallow ground water or surface water condition can and may develop in areas where no such water condition existed prior to site development; this is parti- cularly true where a substantial increase in surface water infiltration results from landscape irrigation. LIMITATIONS The elevations of compaction tests shown as finished grade (FG) tests on the attached forms correspond to the elevations shown on the Grading Plans for Calavera Hills, Carlsbad Tract 76-12 dated October 30, 1979 latest revision dated October 8, 1980, prepared by Rick Engineering Company with the exception of Lots 8 through 12 which were raised .7 to 2.0 feet. Ele- vations and locations used in this report were based on field surveys done by others. - - ‘, . - Pacific Scene I., ,, April 29, 1981 "c Wq !ward-Clyde Consultants Project No. 502161-FCOl Page 5 -. - ~- - - The soil conditions described in this report are based on observations and periodic testing. This office should be notified of any indications that soil conditions are not as described herein. We will inspect foundation excavations for each lot if we are requested to do so. For this report, rough lot grade is defined as that grade set in the field by the grade checker from reference stakes estab- lished by the surveyor, and represents rough grade at the time we were inspecting the grading operation. Likewise, the indicated depths of undercutting of expansive soil and/or depths of placement of nonexpansive soil were based on the measurements made by and grades set by the contractor's grade checker. - - - The conclusions and opinions drawn from test; results and site inspections apply only to our work with respect to grading, and represent conditions at the date of our final inspection. We will accept no responsibility for any subsequent changes made to this site by others, or by uncontrolled action of water, or by failure of others to properly repair damages by uncontrolled action of water. please give us a call.
