Subject Project No. 99-1147A3 Report of Engineering Observation of Grading and Testing of Compacted Fill Proposed Condominium Building Site 137 - 143 Jupiter Street Encinitas, California Dear Mr. Marinkovich: In accordance with your request, we have provided engineering services in conjunction with the grading for the proposed condominiuim building site on subject property, more specifically referred to as being Assessor's Parcel No. 254-222-34, in the City of Encinitas. State of California. DESCRIPTION OF PROJECT The proposed development consists of grading of the site to receive a four-unit condominium complex. The proposed structures will be one story over the parking garage. SCOPE OF WORK Our services included Providing engineering operation; observation of the grading Performing field density tests in the placed and compacted fill; Performing laboratory tests on samples of the material used for fill; and Providing professional opinions regarding the contractor's general adherence to the geotechnical portion of the plans and specifications. Project No. 99-1147A4 Mike Marinkovich 04/26/00 Page 2 137 - 143 Jupiter Street SUMMARY OF GENERAL EARTHWORK AND TESTING Site preparation. grading. compaction and testing were accomplished during the period between March 27 and April 3. 2000. In our opinion. based on our observation and testing. the earthwork performed during the above period was in substantial conformance with the recommendations as presented in the "Update of Preliminary Geotechnical Investigation" Report for subject property prepared by our firm (Project No. 99-1147A3. dated May 8. 1999). During the observed. grading operation. certain earthwork These include : operations were Removal and recompaction of existing loose fill soils on the site. Over-excavation of pad to a depth of soils. the natural soils on the building 30 inches. and recompaction of these The elevation at which the tests were taken and the final test results are presented on page T-1. under "Table of Test Results". The laboratory determinations of the maximum dry densities and optimum moisture contents of the fill soils are set forth on page L-1. under "Laboratory Test Results". The approximate location of the compacted filled ground and field density tests are presented on Figure No.1. entitled. "Approximate Location of Compacted Filled Ground". The results of the tests and observations indicate that the fill soils placed and tested have been compacted to at least 90 percent of maximum dry density. Test results indicate that these soils will support the proposed residential building without detrimental settlement. provided that all recommendations contained herein are followed. SUMMARY OF FINISH GRADE SOIL CONDITIONS Observations and laboratory tests indicate that soils placed or remaining within the upper 3 feet below finished grade are classified as having low expansion potential (Expansion Index = 45) . Project No. 99-1147A3 Mike Marinkovich 04/26/00 Page 3 137 - 143 Jupiter Street RECOMMENDATIONS Foundation for Structures ---------- --- ---------- in the competent natural an allowable soil bearing live loads). The above by one third for loads It is recommended that footings founded or compacted fill soils be designed for value of 1,500 psf (total dead plus bearing value may be further increased that include wind or seismic forces. Footings should be founded at least 18 inches below the lowest adjacent ground surface. Spread or continuous footings should have minimum widths of 24 and 12 inches, respectively. It is recommended that all continuous footings be reinforced with two #5 rebars; one rebar located near the top, and the other rebar near the bottom of the footings. Isolated pier footings should be reinforced with two #5 rebars each way, placed at mid- height of the footing. It is recommended that the foundation be setback at least 7 feet back Foundations placed closer to the top be deepened such that the outer edge bottom is at least 7 feet back from level. for the proposed structure from the top of slope. of slope than 7 feet should of the foundation along the the face of slope at that Concrete Slab on Grade -------- ---- -- ----- It is recommended that all concrete slabs-on-grade should be at least 4 inches net in thickness, and be reinforced with a minimum of 6x6-10/10 welded wire mesh, placed at mid-height of slab. The concrete slab should be underlain by 4 inches of clean sand and a moisture barrier in moisture sensitive areas. Please note that the above footing and slab recommendations are minimum requirements based on soil characteristics, and should be superseded by any requirements of the structural engineer or architect. Additional Fill and Utility Trenches ---------- ---- --- ------- -------- report discusses the fill placement observed by personnel our firm during the periods specified. It is recommended any additional fill placed, like those in the proposed This from that Project No. 99-1147A3 Mike Marinkovich 04/26/00 Page 4 137 - 143 Jupiter Street parking areas, behind retaining walls, as well as backfill placed in utility trenches located within 5 feet of any improvements and deeper than 12 inches, or backfill placed in any trench located 5 feet or more from a building and deeper than 5 feet, be compacted under our observation and tested to verify compliance with the earthwork specifications for the project. The surface of trench backfill frequently settles even when backfill is placed under optimum conditions. It is recommended that the design of any facilities such as buildings, slabs-on- grade, etc., placed upon such fill, be designed to accommodate the potential settlement. Surface Drainage Proper control of the site drainage and regular maintenance of all drainage facilities are important factors related to the overall stability of the soil mass. No surface water should be allowed to collect and/or pond on the building pads, and the runoff should be directed to flow into the street gutter or other suitable on-site drainage facilities without intermediate ponding. Scheduling Earthwork Observations and Testing Services It is our intent to provide prompt, efficient and effective earthwork observation and testing services. To provide such services, the cooperation of our client is requested. Please provide us with lead time regarding the need for our field services of at least 48 hours whenever possible. We may not be able to fill requests for services made later than 4 p.m. of the previous evening. LIMITATIONS The soil conditions described in this report are based on obser- vations and periodic testing.

P-1124 pag e 2 INTRODUCTION This report presents the results of our geotechnical inves- tigation. The purpose of this study was to determine the nature and characteristics of the earth materials underlying the property and their influence on the construction of the proposed condominium. SITE CONDITIONS The property is located on the south side of Jupiter Street approximately mid-way between Neptune Avenue and Old Highway 101 in Leucadia, California. The site is a rectangular lot which originally descended to the east at a gradient of about 10 percent. However, grading on the site has created two pads with intermittent fill slopes ranging in height from 2.0 to 8.0 vertical feet with gradient of about 2:1. The site is bounded on the south by a condominium which is under construction. A single-family residence and an apartment complex bound the property on the west and east, respectively. A 5.0- foot-high retaining wall is located adjacent to the eastern property line. PROPOSED DEVELOPMENT Preliminary plans for the proposed development were provided by Mr. Micheal Winfield, A.I.A. The plans include a parking area located in the central portion of the site at about the existing August 22, 1989 W.O. P-1l24 Pag e 3 grade. Access to the parking area will be via a driveway along the eastern property line. The proposed units will be two--story structures with attached garages. The northern units will be constructed at about the present grade. The southern units will be constructed at elevations ranging from 70 to 72 feet. SITE INVESTIGATION Seven exploratory borings were excavated on the site with a portable auger drill rig to a maximum depth of 8.0 feet. Earth materials encountered were visually classified and logged by our field engineer. Undistur bed, representative samples of the earth materials were obtained at selected intervals. Samples were obtained by driving a thin-walled steel sampler into the desired strata. The samples were retained in brass rings of 2.50 inches inside diameter and 1.00 inches high. The central portion of the sample was retained in close-fitting, waterproof contrainers and tranported to our laboratory for testing and analysis. LABORATORY TESTING Classification The field classification was verified through laboratory exam- ination in accordance with the Unified Soil Classification System. The final classification is shown on the enclosed Boring Logs. August 22, 1989 W.O. P-1l24 pag e 4 Moisture/Density The field moisture content and dry unit weight were determined for each of the undisturbed soil samples. The information is usefel in providing a gross picture of the soil consistency or variation among exploratory excavations. The dry unit weight was determined in pounds per cubic foot. The field moisture was determined as a percentage of the dry unit weight. Both are shown on the enclosed Boring Logs. GEOTECHNICAL CONDITIONS Artificial Fill Previous grading on the site has generated cut/fill transitional pads. Fill deposits along the outside edge of the northern pad appear to reach a maximum depth of about 6.0 feet. Fill deposits along the outside edge of the southern pad are approximately 8.0 to 9.0 feet deep. The fill deposits are classified as tan silty sand in a dry and loose condition. Soil Approximately 1.0 to 2.0 feet of soil was encountered in the western portion of the site. The soil is typically fine- and medium-grained sand in a dry, loose condition. August 22, 1989 w.o. P-1l24 Pag e 5 Terrace Deposit The soil and fill on the property is underlain by reddish-brown fine- and medium-grained sandstone. This sedimentary unit is weathered to a loose condition and poorly cemented in the upper few feet but becomes increasingly dense with depth. CONCLUSIONS AND RECOMMENDATIONS Grading The existing fill and soil on the site should be removed to the underlying terrace deposit and replaced as properly compacted fill. Cut/fill transitions should be undercut a minimum of 3.0 vertical feet and replaced with properly compacted fill. On-site materials are suitable for re-use provided they are cleaned of all vegetation and debris. Fill should be placed in 6.0 to 8.0 inch lifts, moistened as required and compacted to a minimum of 90 percent of the laboratory maximum dry density. Driveway The proposed concrete auto court should be a minimum of 4.0 inches thick and reinforced with 6x6-10xlO welded wire fabric. The proposed asphaltic concrete driveway should be a minimum of 2.0 inches thick and placed over a subgrade that is compacted to a minimum of 90 percent of the laboratory maximum dry density. August 22, 1989 W.O. P-1l24 Pag e 6 Foundations Footings for the proposed structure should be a minumum of 12 inches wide and founded a minimum of 18 inches below the lowermost adjacent grade. A 12-inch by 12-inch grade beam should be provided across the garage opening. Footings founded a minimum of 18 inches into compacted fill may be designed for a bearing value of 1500 pounds per square foot. The bearing value indicated above is for the total of dead and frequently applied live loads. This value may be increased by 33 percent for short dur ations of loading, including the effects of wind and seismic forces. Resistance to lateral load may be provided by friction acting at the base of foundations and by passive earth pressure. A coefficient of friction of 0.35 may be used with dead-load forces. A passive earth pressure of 250 pounds per square foot, per foot of depth of fill or conglomerate penetrated to a maximum of 1500 pounds may be used. Retaining Wall The pr opo sed eastern wall wh ich suppo r ts a level sur charge should be designed to resist an equivalent fluid pressure of 35 pounds per cubic foot. The wall should be provided with an adequate August 22, 1989 w.o. P-1l24 pag e 7 backdrainage system. Backfill behind the wall should consist of granular deposits compacted to a minimum of 90 percent of the laboratory maximum dry density. Slabs On Grade Slabs on grade should be a minimum of 4.0 inches thick and reinforced in both directions with No. 3 bars placed 24 inches on center. The slab should be underlain by a minimum 4-inch sand blanket. Utility trenches underlying the slab may be backfilled with the on-site granular materials. However, sufficiently compacting the backfill deposits may damage or break shallow utility lines. Therefore, minor settlement of the backfill in the trenches is anticipated. To reduce the possibility of cracks occurring, the slab should be provided with additional reinforcement to bridge the trenches. Drainage Pad water should be directed away from foundations and around the structure to an approved location. Roof water should be collected and conducted to the driveway or suitable location via non-erodible devices. Pad water should not be allowed to pond. Inspections and Density Testing All structural footing excavations should be inspected by a representative of this fir~ prior to the placement of any steel. August 22, 1989 W.O. P-1l24 pag e 8 All fill should be placed under the observation and testing of a representative of this firm. Plan Review A copy of the final building plans should be submitted to this office for review prior to the initiation of construction. Additional recommendations may be necessary at that time.

The recommendations contained in the pre- liminary geotechnical investigation report are a part of the rec- ommended grading specifications and would supersede the provi- sions contained herein in case of conflict. INSPECTION AND TESTING A geotechnical engineer should be employed to observe and test the earthwork in accordance with these specifications. It will be necessary that the geotechnical engineer or his representative make adequate observations so that he may provide a memorandum that the work was or was not accomplished as specified. Devia- tions from these specifications will be permitted only upon written authorization from the geotechnical engineer. It should be the responsibility of the contractor to assist the geotechnical engineer and to keep him apprised of work schedules, changes and new information and data so that he may provide the memorandum to the owner and governmental agency as required. If in the opinion of the geotechnical engineer, substandard cond- itions such as questionable soil, poor moisture control, inade- quate compaction, adverse weather, etc. are encountered, the contractor should stop construction until the conditions are remedied. Unless otherwise specified, fill material should be compacted by the contractor while near the optimum moisture content to a dens- ity that is not less than 90 percent of the maximum dry density determined in accordance with ASTM Test No. D1557-78 or other density test methods that will yield equivalent results. CLEARING AND PREPARATION OF AREAS TO RECEIVE FILL All trees, brush, grass and other objectionable material should be collected, piled and burned or otherwise disposed of by the contractor so as to leave the areas that have been cleared with a neat and finished appearance, free from unsightly debris. All vegetable matter and objectionable material should be removed by the contractor from the sur face upon which the fill is to be placed, and any loose or porous soils should be removed or comp- acted to the depth determined by the geotechnical engineer. The surface should then be plowed or scarified to a minimum depth of 6 inches until the surface is free from uneven features that would tend to prev~nt uniform compaction by the equipment to be used. When the slope of the natural ground receiving fill exceeds 20 percent (5 horizontal to 1 vertical), the original ground should be stepped or benched as shown on the attached plate. Benches should be cut to a firm, competent soil condition. The lower bench should be at east 10 feet wide and all other benches at least 6 feet wide, ground slopes flatter than 20 percent should be benched when considered necessary by the geotechnical engineer. FILL MATERIAL Materials for compacted soil should consist of any material im- ported or excavated from the cut areas that in the opinion of the geotechnical engineer is suitable for use in constructing fills. The material should contain no rocks or hard lumps greater than 12 inches in size and should contain at least 40 percent of material smaller than 1/4 inch in size. (Materials greater than 6 inches in size should be placed by the contractor so that they are sur- rounded by compacted fines; no nesting of rocks will be per- mitted.) No material of a perishable, spongy or otherwise improper nature should be used in filling. Material placed within 36 inches of rough grade should be select material that contains no rocks or hard lumps greater then 6 inches in size and that swells less than 3 percent when compacted (as specified later herein for compacted fill) and soaked under an axial pressure of 150 psf. Potentially expansive soils may be used in fills below a depth of 36 inches and should be compacted at a moisture greater than the optimum moisture content for the material. PLACING, SPREADING AND COMPACTING OF FILL Approved mateLial should be placed in areas prepared to receive fill in layers not to exceed 6 inches in compacted thickness. Each layer should have a uniform moisture content in the range that will allow the compaction effort to be efficiently applied to achieve the specified degree of compaction to a minimum speci- fied density with adequately sized equipment, either specifically designed for soil compaction or of proven reliability. Compaction should be continuous over the entire area and the equipment should make sufficient trips to ensure that the desired density has been obtained throughout the fill. When moisture content of the fill material is below that specified by the geotechnical engineer, water should be added by the Con- tractor until the moisture content is as specified. When the moisture content of the fill material is above that specified by the geotechnical engineer, the fill material should be aerated by the contractor by blading, mixing or other satis- factory methods until the moisture content is as specified. The surface of fill slopes should be compacted and there should be no excess loose soil on the slopes.

The geotechnical engineer will make field density tests in accord- ance with ASTM Test No. 01557-78. Density tests will be made in the compacted materials below the surface where the surface is disturbed. When these tests indicate that the density of any layer of fill or portion thereof is below the specified density, that particular layer or portion should be reworked until the specified density has been obtained. The location and frequency of the tests will be at the soil engi- neer's discretion. In general, the density tests will be made at an interval not exceeding 2 feet in vertical rise and/or 500 cubic yards of embankment. PROTECTION OF WORK During construction, the contractor should properly grade all excavated surfaces to provide positive drainage and prevent pond- ing of water. He should control surface water to avoid damage to adjoining properties or to finished work on the site. The con- tractor should take remedial measures to prevent erosion of fresh- ly graded areas and until such time as permanent drainage and erosion control features have been installed.
