During the grading period, fill was placed, compacted, and tested on Pads 1, 18 through 23, 57 through 79, 81 through 170, 172 through 183, 195, 218 through 250, 252 through 276, 278 through 281, 289 through 296, 303 through 308, on three Jacuzzi pads, and on two tennis court areas and the recre- ation pad west of Pad 247. Pads 2 through 16, 24 through 46, 48 through 56, 184 through 189, 191 through 194, 196 through 217, 282 through 288, 297 through 300, 302, and the recreation pad in the lake area are cut pads. Areas numbered 17, 47, 80, 171, 190, 251, 277, and 301 are open space areas. The grading generally consisted of excavating loose surface pacting areas to receive fill, and making cuts and fills to and uncompacted fill soils, scarifying, watering and com- design grade. An existing waterline was removed from the area of Pads 29 through 92, 167, and 174 and the excavation refilled with compacted and tested soil. An old 8 inch steel well casing was found north af pads 307 and 308 in the pond bottom and was filled with 1/2-inch pea gravel, then lake area. This casing was cut off about 6 feet below the was allowed to overflow to produce an apron around the well capped with about 10 to 20 feet of concrete. The concrete casing about 3 feet in diameter and about 5 inches thick. Storm drain backfill was compacted and tested between north of Pads 170 and 172 and west of Lowder Lane. In Pads 119, 120, 166, and 167. Excess material was stockpiled addition to this, ground surfaces were prepared and compacted fill placed to provide for road widening along Poinsettia Lane and Lagoon Lane east of the subject subdivision. 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 observa- tions and results of field density tests indicate that the fill has been generally compacted to 90 percent or more of maximum laboratory dry density as determined in accordance witNl~m ~~~~~~~~~~n~~~~~~en~~~~~~~~~~~~~ tes-r@mwdewereifw ssrtscmrgmcUpwd~a~,~ ,q h e p advise You that Since this correspondence was issued, there have &ep of the profession, as Well as in the degree of risk considered acceptable substantial changes in the state of the art and the state of practice cOncluSionS contained herein may be invalid and must be reevaluated. by and Profession.

For reference, the approximate locations of field density tests and the limits of compacted fill have been recorded'on a copy of the grading plan. The results of dry density (relative compaction), are given on the attached field density tests, expressed as a percent of laboratory forms . Laboratory tests were made on representative samples of the materials used for fill. The tests were performed to evalu- ate moisture density relationships, maximum dry density, plasticity, strength, and swell characteristics. The optimum moisture content, grain size distribution, and results of laboratory tests ar.e attached. SUMMARY OF FINISH GRADE SOIL CONDITIONS Fill Pads and Fill Portion of Cut-Fill Pads Inspection and laboratory tests indicate that nonexpansive fill was placed within 2 feet of rough grade on all fill pads and on the fill portion of cut fill pads noted herein. Cut Pads and Cut Portion of Cut-Fill Pads An inspection of cut pads and the cut portion of cut-fill pads at the completion of grading indicated that no ex- pansive soil is evident at rough grade surface. RECOMMENDATIONS Foundations for Structures on Nonexpansive Soils We recommend that foundations for single- or two-story, residential structures placed on nonexpansive, undisturbed for a bearing pressure not exceeding 2,000 psf (dead plus soil or on nonexpansive, properly compacted fill be designed live loads). We recommend that footings be founded at least 12 inches below finish grade, and have a minimum width of increased by no more than one-third for loads that include 12 inches. In our opinion, this bearing pressure can be wind or seismic forces.

Fill slopes were treated by periodically backrolling with a sheepsfoot compactor, track rolling with a vibratory compactor and grid rolling. The 1-1/2 to 1 slope along the western boundary was excavated and recompacted to an indicated 90 percent relative compaction when initial tests showed an indicated relative compaction of less than 90 percent. We recommend that structures that will not tolerate differ- ential settlements (such as foundations, swimming pools, concrete decks, walls, etc.) not be located within 8 feet of the top of a slope. We recommend th&t footings that are located within 8 feet of the top of a slope be extended in depth until the outer bottom edge of the footing is 8 feet horizontally from the outside face of the slope. Additional Fill and Utility Trenches This report discusses the fill placement observed by person- nel from our firm during the period specified. We recommend that any additional fill placed, as well as backfill placed deeper than 12 inches, or backfill placed in any trench in utility trenches located within 5 feet of a building and located 5 feet or more from a building and deeper than 5 feet, be compacted under our observation and tested to verify compliance with the earthwork speci.ficati0n.s for the project. We should be contacted at least 24 hours prior to back- filling operations. Drainage We recommend that positive measures be taken to properly finish grade each pad after structures and other improve- ments are in place, so that drainage waters from the pad and adjacent properties are directed off the pad 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 partic- ularly true where a substantial increase in surface water infiltration results from landscape irrigation.

For this report, rough pad grade is defined as that grade set in the field by the grade checker from reference stakes established 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.
