The project consisted of removing and recompacting artificial fill and native soils and placing primary structural fill soils to support the proposed villas. Sub-surface soil conditions were SIR mmarized in our Geotechnical Investigation Report dated November 11, 2004, Project No. 444- 3161, Report No. 03-10-183. The proposed construction area was first stripped of surface vegetation and debris and. this material was hauled from the site. .. Within the proposed building area and at least 5.0 foot wide perimeter strip beyond the building walls, all artificial fill and some native soils were removed. Removals extended to a depth of at least 2 feet below bottom of footings. The exposed soils Were then scarified to a depth of 6 inches, brought to near optimum moisture content arid compacted to. at least 90% of maximum dry density as determined by test method ASTM D 1557-90. The excavated soils, generally silty sands, were cleaned of deleterious material and then replaced in 6 inch layers,, brought to near optimum moisture content and compacted. Removals and recompaction resulted in a maximum fill depth of approximately 4.5 feet. Compaction was obtained using a Caterpillar 953 track loader. . Field tests and inspections were performed during the work. The test results indicated compliance with the project specifications at the tested locations but are no guarantee or warranty of the contractor's work. Field Tests: In-place density tests were performed at the approximate locations indicated on the attached site plan using a calibrated sand cone in' accordance with test method ASTM D 1556-90. Field moisture tests determinations were made at the time of each test. Testing indicates that the required compaction of 90% has been attained in the areas tested. , ' March 22, 2005 ., '(2) , Project No. 422-5019 05-03-079 Laboratory Tests: The moisture-density relationships for the tested soils were determined in accordance with test method ASTMD 1557-91. Recommendations: Footings should extend at least 18 inches beneath lowest adjacent grade. Isolated square or rectangiilar footings at least 2 feet square may be designed using an allowable bearing pressure of 2500 pounds per square foot. Continuous footings at least 12 inches wide may be designed using an allowable baring value of 2000 pounds per square foot. The allowable bearing pressures may be increased by 200 psf for each additional one foot of width and 250 psf for each additional 6 inches of depth, if desired. The maximum allowable bearing S pressure should be 3000 psf. • S The allowable bearing pressure are for dead' and . frequently applied live loads and may be increased by 1/3 to resist wind, seismic or other transient loading. Drainage form the building ' area should be rapid and complete'. S ' • S All, footing and utility trench' backfill should be compacted to 90% of maximum dry. density.

The project consisted of removing and recompacting artificial fill and native soil and placing primary structural fill soils to support the proposed ballroom building. Sub-surface soil conditions were summarized in our Geotechnical Investigation; Project No. 544-2063 dated June 28, 2002, Report No. 02-06-361. . The proposed construction area was first stripped of surface vegetation and debris and this material was removed from the site. Within the proposed building area and at least 10 foot wide perimeter strip beyond the building walls, all artificial fill and at least the upper 2 feet of on-site soil was removed. The exposed native soils comprised of silty sand and clayey sands were inspected and approved prior to placing fill by a representative of Sladden Engineering then scarified to a depth of 6 inches, brought to near optimum moisture content and compacted to 90% Of maximum dry density as determined by test method ASTM D 1557-91. The excavated soils, generally silty and clayey sands, were cleaned of deleterious material and then replaced in 6 inch layers, brought to near optimum moisture content and compacted. Removals and recompaction resulted in a maximum fill depth' of approximately 15 feet. Compaction was obtained using a 824 dozer, 623 F & 513 C Caterpillar scraper, D-6 Dozer, 345 B excavator and a skip loader, 12 G motor grader. There is an isolated area approximately 25' foot in diameter around an. existing water line valve to be backfilled and compacted at a later day. The existing 6" and 12" A.C.P. water lines were left in place in the southern portion of the new building pad and will be abandoned at later date. Field tests and' inspections were performed during the work. The test results indicated compliance with the project specifications at the tested locations but are no guarantee or warranty of the contractor's work. April 9, 2003 (2) Project No. 422-'2178 03-04-043 Field Tests: 1nplace density tests were performed at the approximate locations indicated on the attached site plan using a calibrated sand cone in accordance with test method ASTM D 1556-90. Laboratory Tests: The moisturedensity relationships for the tested soils were determined in accordance with test method ASTM D 1557-91. Recommendations: Footing shOuld extend at least 18 inches beneath lowest adjacent grade. Isolated square or rectangular footing at least 2 feet square may be designed using an allowable bearing value of 2500 pounds per square foot. Continuous footing at least 12 inches wide may be designed using an allowable bearing value of 2000 pounds per square foot. The allowable bearing pressures may be increased by 200 psf for each additional one foot of width and 250 psf for each additional 6 inches of depth. The maximum allowable bearing pressure should be 3500 psf. The allowable bearing' pressures are for dead and frequently applied live loads and may by increased by 1/3 to resist wind, seismic or other transient loading. Care should be taken to see that bearing or subgrade soils are not allowed to become saturated form thepounding of rainwater or irrigation. Drainage from the building area should be rapid and complete. All wall, footing and utility trench backfill should be compacted to 90% of maximum dry density.
