Project No. VP-6214-01 Verizon Wireless — Fisher Floral proposed project would not have an adverse impact on adjacent proper recommendations contained in this report and applicable standards are design and construction, and our recommended quality control measures during construction. Foundation Design Recommendations Enclosure Wall CITY OF SANTA ANA Planning and Building Agency Approved FOR PERMIT ISSUANCE s provided our in Enclosure walls may be supported by conventional continuous footing 18 inches wide and 18-inches deep bearing on competent materials or newly compacted fill, and may be designed for an allowable bearing value of 1,500 psf. Based on test results, the underlying surface soils are non -expansive; therefore, special measures will not be required for expansion potential. The subgrade for slab on grade should be kept moist (optimum moisture) at top 12 inches and be incorporated with reinforcement of #3 bars 12 inches center to center each way. The slab thickness should be 5 inches minimum and shall be placed over approved subgrade. Other aspects of the design, including minimum reinforcement, footing embedment, additional posts and beams, and the need for interior footings, are to be determined by the project structural engineer. Equipment Cabinets & Generator Pads Based on test results, the underlying surface soils are non -expansive, therefore, special measures will not be required for expansion potential. However, the top 12 inches of soil may be excavated and re -compacted back to at least 90% of ASTM D 1557 laboratory Standard. The subgrade for slab on grade should be kept moist (optimum moisture) at top 12 inches and be incorporated with reinforcement of #3 bars 18 inches center to center each way. The slab thickness should be 4 inches minimum and shall be placed over approved subgrade. It is highly recommended to remove tree roots during site preparation. 9
