Box 35 San Marcos, California 92069 Subject: REPOtT OF SOIL INVESTIGATION Heli-Hangar Aircraft Road and Palomar Airport Road Carlsbad, California Dear Mr. Staley: In accordance with your request, Geotechnical Exploration, Inc. has performed an investigation of the surface and subsurface soil conditions at the location of the subject proposed Heli-Hangar Building Site. The field work was performed on 21 October 1980 by our Project Engineer. It is our understanding that the site is being developed to receive a concrete tilt-up hangar. The structure is to be a maximum of one story in height and will be on conventional, continuous foundations or spread footings with concrete slab on grade. It is further our understanding, three (3) concrete helicopter landing pads will be located west of the proposed building. Our investigation revealed moderately compacted fill soils up to thirteen (13) feet in thickness exist at the western limit of the proposed helicopter landing pads. The proposed building area, in general, is underlain with good bearing sands. Moderately expansive topsoils were encountered near the surface. In our opinion, if the conclusions and recommendations presented in this report are implemented during site preparation, the site will be suited for the proposed develop- ment. This opportunity to be of service is sincerely appreciated. Should you have any ques- tions concerning the following report, please do not hesitate to contact us. Refer- ence to our Job No. 80-1580 will expedite response to your inquiries. Respectfully submitted, GEOTECHNICAL EXPLORATION, INC. RaymoriØ J. Scaran( Ha, Vice President RJS:med Enclosures 8145 RONSON ROAD, SUITE H • SAN DIEGO, CALIFORNIA 92111 • (714) 560-0428 REPORT OF SOIL INVESTIGATION Heli- Hangar Aircraft Road and Palomar Airport Road Carlsbad, California JOB NO. 80-1580 The, following report presents the findings and recommendations of GEOTECHNICAL EXPLORATION, INC. for the subject project. SCOPE OF WORK It is our understanding, based on communications with Mr. Doug Staley, that the site is intended for the construction of a concrete tilt-up helicopter hangar and three (3) concrete slab helicopter landing pads. The proposed building will be founded on continuous perimeter foundations with concrete floor slab on grade. The proposed improvements will be founded at the existing grade. With the above in mind, the Scope of Work is briefly outlined as follows: Identify and classify the surface and subsurface soils to depths, in conformance with the Unified Soil Classification System (refer to Appendix A). Determine the allowable bearing pressures for the natural ground and the soils to be used in compacted fill, based on their shear-strength characteristics and our experience with the soils. Recommend treatment for any expansive soils and/or uncompacted fill soils that could cause detrimental damages to the proposed structure. Predict the settlement of the natural-ground soils, as well as recompacted fill soils (recompacted to at least 90 percent of Maximum Dry Density), under the proposed structural loads. Hell-Hangar Job No. 80-1580 30 October 1980 Page 2 SITE The site, consisting of approximately 1.2 acres, is located northwest of the intersection between Palomar Airport Road and Aircraft Road, in the Carlsbad area. The property is roughly rectangular in shape, being approximately 85 feet in width and approximately 700 feet in length. The property is bordered on the north and east by Aircraft Road, on the south by Palomar Airport Road and to the west by undeveloped land. Presently, the site is undeveloped and supports a light to moderate growth of chaparral. A previous grading operation generated a relatively level pad that drains gently towards the southwest. The eastern half of the south property line is bordered by a cut slope constructed at a ratio of 1.0 horizontal to 1.0 vertical and ranging from three (3) to six (6) feet in vertical height. Rough field measurements indicate the top of the existing cut slope is located south of the south property line. FIELD Five (5) test trenches were placed on the site, specifically in areas where structures and improvements will be located. The test trenches were located in the field by referring to a Site Plan, prepared by Lusardi Construction, dated 8 October 1980. The test trenches were visually inspected by our Field Engineer, and samples were taken of the predominant soils throughout the field operation. Trench logs have been prepared on the basis of our inspection and the results have been summarized on Figure No. II. The predominant soils have been classified in conformance with the Unified Soil Classification System (refer to Appendix A). SOILS The soils encountered in the proposed building area consist of a topsoil approximately one and one-half (1 1/2) feet in thickness. The topsoils primarily consist of brown, fine to medium grained, clayey sands. These soils are in a loose to medium dense state and are classified as moderately expansive; therefore, possess a swell range from four (4) to six (6) percent as measured by the County of San Diego Test for Expansive Soils. Heli-Hangar Job No. 80-1580 30 October 1980 Page 3 Underlying the topsoils and extending at depth are medium dense, light brown to gray, fine, formational sands. These soils possess good strength characteristics for bearing support and slope stability. The formational sands are classified as nonexpansive; therefore, possess less than three (3) percent swell. Encountered at the west edge of the proposed building and extending to the west property line, underlying the proposed helicopter pads are poorly to moderately compacted fill soils. The fill soils are primarily composed of silty sand and sands with some asphalt debris. The fill soils encountered were classified as nonexpansive; therefore, possess less than three (3) percent swell. The approximate location of the fill soils is shown on Figure No. I, located at the end of this report. The fill extends to a maximum depth of 15 feet below the existing ground surface at the west end of the proposed helicopter pad. LABORATORY TESTS Laboratory tests were performed on the disturbed and undisturbed soil samples in order to determine their physical and mechanical properties and their ability to sup- port the proposed structure. The following tests were conducted on the sampled soils: Moisture Content Density Determinations Mechanical Analysis Expansion Tests Direct Shear Tests CONCLUSIONS AND RECOMMENDATIONS The following conclusions and recommendations are based upon the practical field investigations conducted by our firm, and resulting laboratory tests, in conjunction with our knowledge and experience with the soils in the Carlsbad area. I leli-Hangar Job No. 80-1580 30 October 1980 Page 4 The natural-ground topsoils on this site consist of one and one-half (1 1/2) feet of brown, fine to medium, clayey sand. The clayey sands were tested and found to possess four (4) to six (6) percent swell, as measured by the County of San Diego Test for Expansive Soils. The topsoils are underlain by medium dense, light brown to gray, fine, formational sands. Unless properly dealt with, the moderately expansive characteristics of the topsoil clayey sands described previously can cause significant damage to the structure and associated improvements (such as those planned for the subject property). In order to reduce significantly the potential for such damage, one of the recommendations herein must be followed: 2.1 If the planned structure and improvements are to be constructed using standard, nonexpansive-soils, design criteria, the site shall be prepared as follows: 2.1.1 The moderately expansive clayey sands shall be removed from all structural areas to a minimum distance of five (5) feet outside perimeter footings. The clay soils shall be removed to a minimum depth of three (3) feet below the proposed, rough, finish-grade elevations. 2.1.2 Excavated areas shall be backfilled with nonexpansive soils (such as onsite, sands or soils obtained from an approved offsite borrow pit). The nonexpansive select materials must be placed and compacted to at least 90 percent of Maximum Dry Density, in accordance with the requirements of the County of San Diego Grading Ordinance. Upon satisfactory completion of the backfilling operation, continuous and spread footings may be designed, in accordance with the soil-bearing value assigned to the compacted nonexoansive fill materials. The continuous and spread footings shall have a minimum width of 12 inches and extend a minimum depth of 12 inches into the compacted fill soils. Hel i-Hangar job No. 80-1580 30 October 1980 Page 5 2.1.3 Areas receiving improvements, such as patios, sidewalks, A.C. pavement (parking areas), et cetera, shall be underlain by at least four (4) inches of compacted fill materials, such as that used in the backfilling operations for building locations. 2.2 if it is intended to construct the proposed structure and improvements on the moderately expansive clay soils without preparation of the site (as described in Recommendation No. 2.1), the following recommendations become applicable: 2.2.1 The continuous foundations and spread footings shall extend a minimum depth of 18 inches into the firm natural ground or compacted fill. The continuous foundations shall be reinforced with two (2) No. 4 steel bars; one (1) bar shall be located near the top of the foundations and one bar near the bottom. 2.2.2 Concrete floor slabs, if used, shall be founded on at least four (4) inches of sand or decomposed granite, overlying visqueen. The slabs shall be reinforced with 6 x 6 - 10/10 steel wire mesh. 2.2.3 Prior to pouring footings and foundations, and prior to placement of floor slab base sections, the clayey soils shall be thoroughly watered such that they possess a moisture content of two (2) percent above optimum moisture content (or more) at a depth of 12 inches below the footing grade. 2.2.4 It is recommended that all nonstructural concrete slabs (such as patios, driveways, sidewalks, et cetera), and all parking areas, be founded on at least four (4) inches of nonexpansive soils. 3. Poorly to moderately compacted fill soils were encountered on the site during our investigation. The fill soils"daylight' with the natural ground soils near Heli -Hangar Job No. 80-1580 30 October 1980 Page 6 the west end of the proposed hangar and increase to a maximum thickness of 15 feet at the western most proposed helicopter pad (see Figure No. I for the approximate location of existing fill soils). It is our opinion, based on typical representative samples taken from the encountered fill soils, that the fill soils possess moderately compressible characteristics, and could consolidate up to two (2) inches, should they become wet or saturated. Should the fill soils be recompacted up to at least 90 percent of maximum dry density, then the settlement potential would be less than 0.5 inches. Prior to preparation of building pads and areas to receive structural improvements, the loose fill soils should be prepared in the following manner: 3.1 All loose fill soils shall be removed to expose firm natural ground. The ground shall then be scarified to 12 inches in depth, watered to approxi- mate optimum moisture contents and shall then be .recompacted to at least 90 percent of Maximum Dry Density in accordance with A.S.T.M. 0-1556, Method D. 3.2 The removed loose soils shall be cleaned of all significant debris and vegetal matter, and shall be watered to approximate optimum moisture contents. 3.3 The prepared fill soils shall then be placed and compacted, as required, to achieve the design elevations for the project. The materials shall be placed in layers, not exceeding six (6) inches in compacted thickness, and shall be compacted to at least 90 percent of Maximum Dry Density. 3.4 The existing fill soils, located in the proposed building area and extending for a distance of at least five (5) feet beyond the perimeter thereof, shall be excavated to a depth exposing firm natural ground, or to a depth approved by the Field Soils Technician. The bottom of the excavation shall be scarified to a depth of at least 12 inches, watered to optimum moisture, content and compacted to at least 90 percent of Maximum Dry Ilel i-Hangar Job No. 80-1580 30 October 1980 Page 7 Density. The excavated fill soils shall be cleaned of debris and deleteri- ous materials. The fill soils shall be placed into the excavation in layers not exceeding eight (8) inches in thickness, then watered to optimum moisture content and then compacted to at least 90 percent of Maximum Dry Density. It is recommended that nonexpansive soils be placed within three (3) feet of finish-ground grade. Utilizing an Angle of Internal Friction of at least 35 degrees, and a cohesion of 300 pounds per square foot (with the appropriate Terzaghi Equation), the maximum safe soil-bearing value (at a depth of 12 inches into the natural materials or compacted fill soils on this site) is at least 2500 pounds per square foot. This soil-bearing value may be utilized in the design of continuous foundations and spread footings when founded a minimum of 12 inches into the firm natural ground or compacted fill. This. soil-bearing value may be increased one third for design loads that include wind or seismic analysis. If imported soils are required to bring the site to grade, the import soils shall be nonexpansive and shall be obtained from an approved offsite borrow area. Based on our laboratory test results and our experience with the soil types on the subject site, the soils will experience settlement in the magnitude of less than 0.5 inch undei a structural load of 2500 pounds per square foot. The active earth pressure (to be utilized in the design of walls, etcetera), shall be based on the following formula and summarized laboratory test results. This active pressure is for level backfill. w = unit weight of soil =1 110 pounds per cubic foot,. h = depth of foundation or footing into ground (feet), = angle of repose of soil (Angle of Internal Friction) = 35 degrees. Pa(Maximum) = w (1 - sin 0) I (1+ sin ) 2 Hell-Hangar Job No. 80-1580 30 October 1980 Page 8 WeW (1-sin) (1 + sin ) Therefore, Pa(MaxilnUm) = weh2 2 We = (110) (1 - 0.57) = 30 pounds per cubic foot. (1 +0.57) Thus, the active earth pressure (at any depth) shall be based on an Equivalent Fluid Pressure of 30 pounds per cubic foot. 7. The passive earth pressure of the encountered natural-ground soils (to be used - for design of building foundations and footings to resist the lateral forces) is based on the Rankine Formula and laboratory test results as follows: P(Maximum) = 1/2 wh2 (1 + sin 0) Weh2 (1-sing) 2 where, p = passive earth pressure (pounds per square foot), W = unit weight of soil = 110 pounds per cubic foot, h = depth of foundation or footing into ground (feet), = angle of repose of soil (Angle of Internal Friction) = 35 degrees. We = Equivalent Fluid Pressure = w (1 + Sifl 3) (1 - sin ) Hell -Hangar Job No. 80-1580 30 October 1980 Page 9 Therefore, We = (110) (1 + 0.57) = 402 pounds per cubic foot. (1 - 0.57) The passive earth pressure (at any depth) shall then be based on an Equivalent Fluid Pressure of 402 pounds per cubic foot. A Coefficient of Friction Of 0.4 times the dead load may be used between the bearing soils and concrete wall foundations or structure foundations and floor slabs. The compacted fill soils that occur within five (5) feet of the face of the fill slopes will possess poor lateral stability, even though they have been com- pacted. Proposed structures and other improvements (such as walls, fences, sidewalks, driveways, asphalt paving, et cetera), that are located within five (5) feet of the face of compacted fill slopes, could suffer differential movement as a result of the poor lateral stability of these soils. * Foundations and footings of proposed structures, walls, et cetera, when found- ed five (5) feet and further away from the top of compacted fill slopes, may be of standard design in conformance with the recommended soil-bearing value. If the proposed foundations and footings are located closer than five (5) feet inside the top of compacted fill slopes, they shall be deepened. to one (1) foot below a line beginning at a point five (5) feet horizontally inside the fill slopes and projected, outward and downward, parallel to the face of the fill slope (see Figure No. V). It is recommended that continuous footings be reinforced with at least one (1) No. 4 steel bar, extending a minimum distance of 15 feet to either side of day- light areas. The steel reinforcement will help to prevent damage due to minor differential settlement between the compacted fill soils and the more-dense, natural-ground soils. LI Hell -Hangar Job No. 80-1580 30 October 1980 Page 10 The proposed hangar building is located five (5) feet from the top of a cut slope, constructed at a ratio of 0.5 horizontal to 1.0 vertical. The proposed structure may be designed with a standard-type foundation at a distance of five (5) feet and further from the top of the cut slope. Should plans be modified and the proposed structure encroach closer than five (5) feet from the top of cut slope, then our firm shall be contacted for special foundation recommenda- tions. It is recommended that all compacted fill slopes and natural cut slopes be planted with an erosion-resistant plant, in conformance with the requirements of the County of San Diego. Planter areas and planter boxes shall be sloped to drain away from the founda- tions, footings and floor slabs. Planter boxes shall be constructed with a sub- surface drain, installed in gravel, with the direction of subsurface and surface flow away from the foundations, footings and floor slabs, to an adeqyate drain- age facility. The existing debris and vegetation observed on the site must be removed prior to the preparation of building pads and/or areas to receive structural improve- ments. Existing topsoils, which will not be removed during the future grading opera- tion, shall be scarified (in place) to a depth of 12 inches, watered to optimum requirements, and shall then be compacted to at least 90 percent of Maximum Dry Density. Any septic tanks, subsurface disposal systems, wells, et cetera, which might be discovered on the site, shall be removed and properly backfilled with approved onsite or imported fill soils, and shall then be compacted to at least 90 percent of Maximum Dry Density. Hell-Hangar Job No. 80-1580 30 October 1980 Page 11 18.. Any backfill soils placed in utility trenches, or behind retaining walls, which support structures and other improvements (such as patios, sidewalks, drive- ways, pavements, et cetera), other than landscaping, shall he compacted to at least 90 percent of Maximum Dry Density. It is our opinion that natural-ground cut slopes and compacted fill slopes of maximum inclinations of 1.5-horizontal-to-1.0-vertical shall be stable and free from deep-seated failures for slopes not exceeding 15 feet in height. Adequate measures shall be taken to properly finish-grade the site after the structures and other improvements are in place. Drainage waters from this site and adjacent properties are to be directed away from foundations, floor slabs and footings, onto the natural drainage direction for this area or into properly designed and approved drainage facilities. Proper subsurface and surface drain- age will ensure that no waters will seek the level of the bearing soils under the foundations, footings and floor slabs. Failure to observe this recommendation could result in uplift or undermining and differential settlement of the structure or other improvements on the site. Geotechnical Exploration, Inc. will assume no liability for damage to structures which is attributable to poor drainage. GRADING NOTES Any required grading operations shall be performed in accordance with the general re- quirements of the County of San Diego Grading Ordinance, under the supervision of a qualified soils engineer or supervised field soils technician. It is the responsibility of the Owner and/or Developer to ensure that the recommenda- tions summarized in this report are carried out in the field operations. AMU Heli-Hangar Job No. 80-1580 30 October 1980 Page 12 LIMITATIONS Our conclusions and recommendations have been based on all available data obtained from our field investigation and laboratory analysis, as well as our experience with the soils and formational materials located in this portion of San Diego County. Of necessity, we must assume a certain degree of continuity between exploratory excava- tions and/or natural exposures. It is, therefore, necessary that all observations, conclusions and recouiimeridations be verified at the time grading operations begin, or when footing excavations are placed. In the event discrepancies are noted, we should be notified immediately so that an inspection can be made and additional recommenda- tions issued, if required. This report should be considered valid for a period of three (3) years, and is subject to review by our firm following that time. If significant modifications are made to the building and/or grading plans, especially with respect to the height and location of cut and fill slopes and the height and location of proposed structures, this report must be presented to us for immediate review and possible revision. The firm of Geotechnical Exploration, Inc. shall not be held responsible for changes to the physical condition of the property, such as addition of fill soils or changing drainage patterns, which occur subsequent to issuance of this report. Once again, should any questions arise concerning this report, please do not hesitate to contact us. Reference to our Job No. 80-1580 will expedite response to your inquiries.

APPENDIX B GRADING SPECIFICATIONS General The intent of this item is to properly establish procedures for: cleaning and compacting natural ground, pre- paring areas to be filled, and placing and compacting till material to the grades and slopes as shown on the Grading Plans. Clearing All vegetation, brush and debris shall be removed, piled and burned, or otherwise disposed of, to give the sur- face a neat and finished appearance. Compacting Natural Ground After clearing, the natural ground shall be scarified to a depth of at least 12 inches, watered to optirium requirements and compacted to not les., than 90 percent of maximum dry density, according to A.S.T.M. Test Method D-1557. in a four-inch diameter, cylindrical mold of 1/30th-cubic-foot volume. Field density tests shall be taken in the natural ground in'accordance with A.S.T.M. Test Method 0-1556. Fill Materials Materials for the fill shall be approved by the soils engineer and shall be free from organic matter and other deleterious substances. In the event that expansive materials are encountered within three feet of finished grade. they shall either be entirely removed or thoroughly mixed with good, granular material before incorpo- rating them in fills. No footing shall be allowed to bear on soils which, in the opinion of the soils engineer, are detrimentally expansive—unless designed for this clayey condition. Placing and Compacting Fill Material After preparing the areas to be filled, the fill materials shall be placed in layers not to exceed six inches in compacted thickness. Each layer shall be watered to optimum requirements and compacted to not less than 90 percent of maximum dry density in accordance with A.S.T.M. Test Method D-1557. Compaction of the tilt shall then proceed in the specified manner to the grades as shown on the approved plans. When the slope ratio of the original ground is steeper than five-horizontal-to-one-vertical, the original ground shall be benched. Ground slopes flatter than five-horizontal-to-one-vertical shalt be benched when considered necessary by the soils engineer. Fill slopes shall be compacted by means of a sheepsfoot roller, or other suitable equipment. Slope compaction shall be continued until the slopes are stable but not too dense for planting. Field density tests shall be taken when considered necessary by the soils engineer in accordance with A.S.T.M Test Method 0-1556 and shall be made not exceeding two feet in vertical height providing each layer is tested. Supervision Continuous supervision of the fill shall be made by the representative of Geolechnical Exploration, Inc., during the grading operation so that he can certify that the fill was placed in accordance with these specifict ions. Season Limits No fill material shall be placed, spread or rolled during unfavorable weather conditions. When the work is interrupted by heavy rains, the filling Operation shall not be resumed until field tests indicate that the moisture content and density of the fill are as previously specified. 4
