CITY OF SANTA ANA Planning and Building Agency 518 Huylars Ln Santa Aka CA 92703 At a minimum, the floor slab shall be reinforced with # 4 reinforcing bars placed 18 inchcHpploved center throughout the entire slab and shall be placed in the center of a 5-inch slab fQRN. �ci`dsSUANCE tend to dry out prior to placing the floor slab, therefore, prior to placing concrete, the sub -grade soils shall be remoisturized to 90 % of optimum moisture to a depth of 12 inches. Master ID: Date: Driveways and Parking Areas Asphalt paving shall be a minimum of 2 inches of/z inch maximum aggregate asphalt over 4 inches of 3/4 inch crushed rock, gravel or miscellaneous base. The sub grade shall be compacted to 95% minimum and the aggregate base shall be compacted to 90% of maximum density minimum. Concrete driveways and parking areas shall be constructed a minimum of 4 inches thick with construction joints at a maximum of 10 feet. Minimum reinforcement shall consist of #3 reinforcing bars crossing at 24 inches on center and placed in the center of the slab. The driveway shall be constructed over a minimum of 3 inches of crushed rock, gravel or miscellaneous base. Prior to placing concrete, the driveway sub -grade shall be saturated to 100% of optimum moisture to a depth of 12 inches. Utility Trenches The development of the site will obviously require utility trenches. Although these trenches are limited in scope, they present significant problems when they are not properly dug and properly backfilled. On site material may be used for utility line backfill. The backfill shall be compacted to 90% of max density. Fill placement and compaction requirements Material for engineered fill should be select free of organic material, debris, ad other deleterious sub- stances, and should not contain fragments greater than 3 inches in maximum dimension. On -site exca- vated soils that meet these requirements may be used to backfill the excavated Residential Building area. All fill should be placed in 6 inch thick maximum lifts, watered or air dried as necessary to achieve near optimum moisture conditions, and then compacted in place to a maximum relative compaction of 90%. The laboratory maximum dry density and optimum moisture content for each change in soil type should be determined in accordance with Test Method ASTM D 1557. A representative of the project consultant should be present on -site during grading operations to verify proper placement and compac- tion of all fill, as well as to verify compliance with the other geotechnical recommendations presented herein.
