The fills were placed during the period between February 6, 1973 ond November 18, 1974. The approximate aeo and deptha of filled ground placed under our inspection in acordance with the approved specifications ore shown on the attached Drawing No. 1, entitled “Location of Compacted Filled Ground.” The grading plan used for the placement of filled ground was prepared by Rick Engineering Company. The approximate locations ot which the tests were taken and the final test msults are presented on pages T-l and T-24, inclusive, under the “Table of Test Results.” The laboratory deter- minatlons of the maximum dry densities and optimum moisture contents of the major fill materials are presented on page L-l, under the “Laboratory Test Resulb.” Some of the maximum dry densities shown in the “Table of Test Results’-were combinations of these.

It bar been determined that the fill materiols, compacted ta 90 percent of the maximum dry density, have a safe bearing value of 1650 pounds per squat foot for one foot wide continuous footings founded at a minimum depth and placed five feet or more inside the top of compacted filled ground slopes. If footings are placed closer to the exposed slopes than 5 feet inside the top of compacted filled ground slopes, these should be deepened one foot below a 1 I/2 horizontal to 1 vertical line pro[ected out- ward and downward from a polnt 5 feet horizontally inside the top of compacted filled ground slopes. Tests indicate that the compacted R Iled ground is adoquate ns satisfactorily support the proposed one and two ttary wood frcrne dwellings wlthout detrimental settlements. BENTON ENGINEERIN. INC Pro/ect No. 72-12-5D La Costa Vale Unit No. 2 -3- November 27, 1974 Oversized rocks ‘~)re buried in the slope aea on the southerly side of Lots -St 275 and 276. If footings are placed closer than 5 feet to the top of this slope area, e&f&Id bedeepened one foot below a 1 horizontal to 1 vertical line pro/acted outward and down- wad from a point 5 feet horizontally imide the top of compacted filled ground slope. It II poaible that natural in-place rock formotiom existing in the mea may be encountered during excavation for footings and/ar utility lines. Critically expansive soil condition, exist within the upper three feet below Rnished grade In both cut and fl lled ground areas. Therefore, in order to minimire possible detrimental effech caused by these potentially expensive soils, the following special design md pre- cautions are recommended: 1. 2. 3. 4. 5. b Avoid the use of isolated interior pien. Use continuous interconnected reinforced concrete footings throughout, and place these at a minlmum depth of 24 inches below the lowest adjacent exterior final ground surface. Where in-place rock condltiom exist at shallower depths, then less depth of excavation is permissible to a minimum of 12 inches. Reinforce and interconnect continuously with steel bars all interior and exterior footings with one #5 bm at 3 inches above the bottom of the footings and one #5 bar placed 1 l/2 inches below the top of the stems of the footinp. Raised wooden floors that span between continuous footings are best, or use concrete slabs reinforced with at least 6 x 6 - lO/lO welded wire falxtc. A minimum of 4 inches of crushed rock 3/4 to 1 inch in size shauld be placed beneath all concrete sl&s and covered with a moisture barrier. Two inches of clean sond should then be placed over the moisture barrier and below the bottom of the slob. Separate garage slabs from perimeter footings by o l/2 inch thickness of comtruction felt or equivalent, to allow independent movement of gaoge slab relative to perimeter footings. Assure complete separation by extend- ing the fett over the full depth of the front thickened edge of the gaage slab. Also, cut off the garage door stops at leet l/2 inch above the slab. Provide positive drainwe oway from all perimeter footings with a vertical foil of at leart 5 inches to a horizontal dlrtance of 5 feet ouhide the house wal Is. Exercise every effort to assure that the soil under the concrete slaba has o uniform moisture content at lest 1 to 3 percent greater than optimum throughout the top 1.5 feet below flnished grade at the time of placing the foundatiom and slabs.
