Appendix D SCOPE This report gives our recommendations for the proposed new residence to be located at 599 Camino El Dorado, Encinitas, California. (See Figure No. 1, "Site Vicinity Map ", and Figure No. 2, "Site Location Map "). The scope of our work conducted onsite to date has included a visual reconnaissance of the property and surrounding areas, a limited subsurface investigation of the subject property and preparation of this report presenting our findings, conclusions, and recommendations. AND PROJECT DESCRIPTION For the purposes of this report the property is assumed to face west. The subject property appears to be a rectangular shaped lot located at 599 Camino El Dorado, Encinitas, California. The property is bordered to the north, south by single family homes, to the east by a descending canyon and to the west by Camino El Dorado. The general topography of the site area consists of hillside terrain. The site consists of a relatively flat building pad flanked to the east (rear) by a descending slope to the canyon below. At the time of this report the lot is unimproved. Based upon our conversations with the project developer and our review of the project site plan we understand that development will consist of the following: A new main residence founded on raised foundation with an attached garage Detached accessory unit and carport. SUBSOIL CONDITIONS Based upon our subsurface investigation of the property the site soil profiles and soil types are described as follows: Toosoil/Weathered Sands Topsoil and weathered sands consisting of slightly silty sands with small roots. These profiles extend to depths between approximately 15 inches to 32 inches below adjacent grade. The materials consist of dark to light brown, dry, loose to medium dense, silty sands. Topsoil and weathered sand materials are not considered suitable for the support of structures in their present state. Slightly silty sands classify as SW -SM according to the Unified Classification System, and based on visual observation generally possess potentials for expansion in the low range. Sandstone Sandstone material underlie the topsoillweathered material at the subject site. Sandstone materials consisted of tan to grey, moist, dense to very dense, slightly silty sandstone. Sandstone materials are considered suitable for the support of structures and structural improvements, provided the recommendations of this report are followed. Sandstone materials classify as SW -SM according to the Unified Classification System, and based on visual observation and our experience possess potentials for expansion in the low range.

CML, STRV Tw COF,$V.TI GROUND WATER Ground water was not encountered as part of our subsurface investigation. Groundwater is not anticipated to be a significant concern to the project provided the recommendations of this report are followed. However, in our experience groundwater conditions can develop where no such condition previously existed. Proper surface drainage and irrigation practices will playa significant role in the future performance of the project. Please note in the "Concrete Slab on Grade" section of this report for specific recommendations regarding water to cement ratio for moisture sensitive areas should be adhered. The project architect and /or waterproofing consultant shall specifically address waterproofing details. LIQUEFACTION It is our opinion that the site could be subjected to moderate to severe ground shaking in the event of a major earthquake along any of the faults in the Southern California region. However, the seismic risk at this site is not significantly greater than that of the surrounding developed area. Liquefaction of cohesionless soils can be caused by strong vibratory motion due to earthquakes. Research and historical data indicate that loose, granular soils underlain by a near- surface ground water table are most susceptible to liquefaction, while the stability of most silly clays and clays is not adversely affected by vibratory motion. Because of the dense nature of the soil materials underlying the site and the lack of near surface water, the potential for liquefaction or seismically- induced dynamic settlement at the site is considered low. The effects of seismic shaking can be reduced by adhering to the most recent edition of the Uniform Building Code and current design parameters of the Structural Engineers Association of California. New Residence Page No. 2 599 Camino El Dorado, Encinitas, California Job No. 104714 -1 ENGINEERING DESIGN GROUP GEGTEC"I AL. CML. s7iNcrL Co,suLTN s CONCLUSIONS AND RECOMMENDATIONS GENERAL It is our opinion that the proposed construction, as described herein, is feasible from a geotechnical standpoint, provided the recommendations of this report and generally accepted construction practices are followed. In the area of the proposed new residence unsuitable soil profiles found to mantle the upper 15 to 30 inches are not suitable for the support of settlement sensitive improvements. In consideration of the proposed raised wood floors we anticipate foundation excavations will be deepended through unsuitable profiles and grading will be limited to the slab on grade garage. The following recommendations should be considered as minimum design parameters and shall be incorporated within the project plans and utilized during construction, as applicable. EARTHWORK We anticipate all new building foundations will be deepended through unsuitable profiles and grading will be limited to the slab on grade garage. Grading operations shall be conducted in accordance with the recommendations below as well as the Appendix B of this report, as applicable. 1. Site Preparation Prior to any grading, the areas of proposed improvement should be cleared of surface and subsurface debris (including organic topsoil and vegetative debris). Removed debris should be properly disposed of off -site prior to the commencement of any fill operations. Holes resulting from the removal of debris, existing structures, or other improvements which extend below the underculdepths noted, should be filled and compacted using onsite material or an import material with a low potential for expansion. 2. Removals Fill and weathered profiles found to mantle the site in our trench excavations, upper approximately 22 inches feet, as observed in the field, are not suitable for the structural support of buildings or structural improvements in their present state. We recommend a rip, removal and recompaction in the areas of proposed slab on grade Floors of the garage. In general grading should consist of the removal of unsuitable soil to an anticipated 18 inches and scarification of subgrade to a depth of 12 inches and the re- compaction of fill materials to 90 percent minimum relative compaction. In the area of driveways the upper 18 inches below adjacent grade shall be ripped and recompacted, as described herein. Excavated fill materials are suitable for re -use as fill material during grading, provided they are cleaned of debris and oversize material in excess of 6 inches in diameter (oversized material is not anticipated to be of significant concern) and are free of contamination. 3. Transitions Any structural sensitive improvements should be constructed on a uniform building pad. In consideration of the deepened foundations at the raised floor portion of the building and the shallow removals at the area of the garage, we anticipate all foundations excavations will be deepened and placed on competent sandstone material. New Residence Page No. 3 599 Camino El Dorado, Encinitas, California Job No. 104714 -1 ENGINEERING DESIGN GROUP Gconc"Sc. CNh S� CO MTN 4. Fills All fill in the area of removal and recompaction should be brought to +2% of optimum moisture content, and re- compacted to at least 90 percent relative compaction (based on ASTM D1557-91). Compacted fills should be cleaned of loose debris, oversize material in excess of 6 inches in diameter, brought to near optimum moisture content, and re- compacted to at least 90% relative compaction (based on ASTM 01557 -91). Surficial, loose or soft soils exposed or encountered during grading (such as any undocumented or loose fill materials) should be removed to competent material and properly compacted prior to additional fill placement. Fills should generally be placed in lifts not exceeding 6-8 inches in thickness. If the import of soil is planned, soils should have a low potential for expansion (EI <50), free of debris and organic matter. Prior to importing soils should be visually observed, sampled and tested at the borrow pit area to evaluate soil suitability as fill. Where new foundations extend across a retaining wall backfll wedge footings shall be deepened through fill to competent sandstone. 5. Slopes Permanent slopes may be cut to a face ratio of 2:1 (horizontal to vertical). Permanent fill slopes shall be placed at a maximum 2:1 slope face ratio. All temporary cut slopes shall be excavated in accordance with OSHA requirements. Subsequent to grading, planting or other acceptable cover should be provided to increase the stability of slopes, especially during the rainy season (October thru April). FOUNDATIONS The following design parameters may be utilized for new foundations founded on competent sandstone. Footings bearing in competent sandstone may be designed utilizing maximum allowable soils pressure of 2,000 psf. 2. Seismic Design Parameters: Site Class D Spectral Response Coefficients SM (g) 0.878 Sol (g) 0.496 Bearing values may be increased by 33% when considering wind, seismic, or other short duration loadings. 3. The following parameters should be used as a minimum for designing new fooling width and depth below lowest adjacent grade: New Residence Page No. 4 599 Camino El Dorado, Encinitas, California Job No. 104714.1 ENGINEERING DESIGN GROUP CEOTECMN L. CML. s: Po.CTl1I1K CON$lf -TNIIS No. of Floors Supported Minimum Footing Width "Minimum Footing Depth Below Lowest Adjacent Grade 1 15 Inches 15 Inches 2 15 Inches 18 Inches 3 18 inches 24 Inches 'Fooling depths to be confirmed in the field by a representative of Engineering Design Group prior to the placement of steel and removal of excavation equipment. 4. All footings founded into recompacted fill should be reinforced with a minimum of two #4 bars at the top and two #4 bars at the bottom (3 inches above the ground). For footings over 30 inches in depth, additional reinforcement, and possibly a stemwall system will be necessary, and should be reviewed by project structural engineer prior to construction. 5. All isolated spread footings should be designed utilizing the above given bearing values and footing depths, and be reinforced with a minimum of #4 bars at 12 inches o.c. in each direction (3 inches above the ground). Isolated spread footings should have a minimum width and depth of 24 inches. 6. For footings adjacent to slopes, a minimum of 10 feet horizontal setback in competent material or properly compacted fill should be maintained. A setback measurement should be taken at the horizontal distance from the bottom of the footing to slope daylight. Where this condition can not be met it should be brought to the attention of the Engineering Design Group for review. 7. All excavations should be performed in general accordance with the contents of this report, applicable codes, OSHA requirements and applicable city and /or county standards. 8. All foundation subgrade soils and footings shall be pre - moistened to 2% over optimum to a minimum of 18 inches in depth prior to the pouring of concrete. CONCRETE SLABS ON GRADE Concrete slabs on grade are anticipated at the garage and driveway areas. Concrete slab on grade floors founded on recompacted fill material should use the following as the minimum design parameters. Concrete slabs on grade of the building should have a minimum thickness of 5 inches (5.5 inches at garage and driveway locations) and should be reinforced with #3 bars at 18 inches o.c. placed at the midpoint of the slab. Slump: Between 3 and 4 inches maximum Aggregate Size: 3/4 - 1 inch Air Content: 5 to 8 percent Non - Moisture Sensitive Areas: Compressive Strength = 2500 psi minimum. Moisture Sensitive Areas: Water to cement Ratio- 0.45 maximum Compressive Strength = 4,000 psi minimum (No special inspection required for water to cement ratio purposes, unless otherwise specified by the structural engineer) Moisture retarding additive in concrete at concrete slab on grade floors and moisture sensitive areas. 2. In moisture sensitive areas (i.e. interior living space where slab vapor emission is a concern), the slab concrete should have a minimum water to cement ratio of 0.45, generally resulting in a compressive strength of approximately 4,000 psi (non- special inspected) as determined by the w/c ratio. This recommendation is intended to achieve a low permeability concrete. New Residence 599 Camino El Dorado, Encinitas. California ENGINEERING DESIGN GROUP Job No. 3. The project architect and/or waterproofing consultant should provide all slab underdrain, flooring sealers and various other details, specifications and recommendations (Le Moistslop and l.inkseal) at areas of potential moisture intrusion (i.e. basement slabs and slab penetrations). Engineering Design Group accepts no responsibility for design or quality control of waterproofing elements of the building. 4. All required fills used to support slabs, should be placed in accordance with the grading section of this report and the attached Appendix B, and compacted to 90 percent Modified Proctor Density, ASTM D -1557 (Figure 4), and as described in the Earthwork section of this report. 5. A one inch layer of coarse sand material, Sand Equivalent (S.E.) greater than 50 and washed clean of fine materials, should be placed beneath the slab. Sand should be rounded to avoid puncture of visqueen vapor retarder. In moisture sensitive areas, a visqueen layer (15 mil) should be placed below the upper one inch of sand to act as a vapor retarder. The visqueen layer should extend down the interior edge of the footing excavation a minimum of 12 inches. The visqueen layer should lap a minimum of 6 inches, sealed along all laps with the manufacturers recommended adhesive, and extend down the interior edge of the footing excavation a minimum of 12 inches. Beneath the vapor retarder a uniform layer of 4 inches of pea gravel is recommended under the slab in order to more uniformly support the slab, help distribute loads to the soils beneath the slab, and act as a capillary break. 6. Adequate control joints should be installed to control the unavoidable cracking of concrete that takes place when undergoing its natural shrinkage during curing. The control joints should be well located to direct unavoidable slab cracking to areas that are desirable by the designer. 7. All subgrade soils to receive concrete flatwork are to be pre- soaked to 2 percent over optimum moisture content to a depth of 18 inches. 8. Brittle floor finishes placed directly on slab on grade floors may crack if concrete is not adequately cured prior to installing the finish or N there is minor slab movement. To minimize potential damage to movement sensitive flooring, we recommend the use of slip sheeting techniques (linoleum type) which allows for foundation and slab movement without transmitting this movement to the Floor finishes. 9. Exterior concrete flatwork and driveway slabs, due to the nature of concrete hydration and minor subgrade soil movement, are subject to normal minor concrete cracking. To minimize expected concrete cracking, the following may be implemented: Concrete slump should not exceed 4 inches. Concrete should be poured during "cool" (40 - 65 degrees) weather if possible. If concrete is poured in hotter weather, a set retarding additive should be included in the mix, and the slump kept to a minimum. Concrete subgrade should be pre - soaked prior to the pouring of concrete. The level of pre- soaking should be a minimum of 2% over optimum moisture to a depth of 18 inches. Concrete may be poured with a 10 inch deep thickened edge. Flatwork adjacent to top of a slope should be constructed with a outside footing to attain a minimum of 7 feet distance to daylight. Concrete should be constructed with tooled joints or sawculs (1 inch deep) creating concrete sections no larger than 225 square feet. For sidewalks, the maximum run between joints should not exceed 5 feet. For rectangular shapes of concrete, the ratio of length to width should generally not exceed 0.6 (i.e., 5 ft. long by 3 ft. wide). Joints should be cut at expected points of concrete shrinkage (such as male corners), with diagonal reinforcement placed in accordance with industry standards. Drainage adjacent to concrete flatwork should direct water awayfrom the improvement. Concrete subgrade should be sloped and directed to the collective drainage system, such that water is not trapped below the flatwork. New Residence Page No. 6 599 Camino El Dorado, Encinitas, California Job No. 104714.1 ENGINEERING DESIGN GROUP GEORbMriLL.0 .fTRUGT COV TMTS The recommendations set forth herein are intended to reduce cosmetic nuisance cracking. The project concrete contractor is ultimately responsible for concrete quality and performance, and should pursue a cost - benefit analysis of these recommendations, and other options available in the industry, prior to the pouring of concrete. RETAINING WALLS Retaining walls are not anticipate for the project, but retaining walls up to 6 feet may be designed and constructed in accordance with the following recommendations and minimum design parameters: Retaining wall footings should be designed in accordance with the allowable bearing criteria given in the "Foundations" section of this report, and should maintain minimum footing depths outlined in "Foundations" section of this report. It is anticipated that all retaining wall footings will be placed on recompacted fill material or competent sandstone. Where cut -fill transitions may occur footings may be deepened to competent material or alternative detailing may be provided by the Engineering Design Group on a case by case basis. 2. Unrestrained cantilever retaining walls should be designed using an active equivalent fluid pressure of 35 pcf. This assumes that granular, free draining material with low potential for expansion (E.I. c50) will be used for backfill, and that the backfill surface will be level. Where soil with potential for expansion is not very low (E.I. >50) a new active fluid pressure will be provided by the project soils engineer. Backfill materials should be considered prior to the design of the retaining walls to ensure accurate detailing. We anticipate onsite material will be utilized as retaining wall backfill. For sloping backfill, the following parameters may be utilized: Backfill Sloping Condition 2:1 Slope 1.5:1 Slope Active Fluid Pressure 50 pcf 65 pcf Any other surcharge loadings shall be analyzed in addition to the above values. 1 If the tops of retaining walls are restrained from movement, they should be designed for an uniform at -rest soil pressure of 65 psf. 4. Passive soil resistance may be calculated using an equivalent fluid pressure of 300 pcf. This value assumes that the soil being utilized to resist passive pressures, extends horizontally 2.5 times the height of the passive pressure wedge of the soil. Where the horizontal distance of the available passive pressure wedge is less than 2.5 times the height of the soil, the passive pressure value must be reduced by the percent reduction in available horizontal length, 5. A coefficient of friction of 0.35 between the soil and concrete footings may be utilized to resist lateral loads in addition to the passive earth pressures above. 6. Retaining walls should be braced and monitored during compaction. If this cannot be accomplished, the compactive effort should be included as a surcharge load when designing the wall. 7. All walls shall be provided with adequate back drainage to relieve hydrostatic pressure, and be designed in accordance with the minimum standards contained in the "Retaining Wall Drainage Detail ", Appendix D. The waterproofing elements shown on our details are minimums, and are intended to be supplemented by the waterproofing consultant and/or architect. The recommendations should be reviewed in New Residence Page No. 7 599 Camino El Dorado, Encinitas, California Job No. 104714 -1 ENGINEERING DESIGN GROUP GEOIECHWK .OM, StPUCY� C U:TMTS consideration of proposed finishes and usage performance expectations and budget. If deemed necessary by the project owner, based on the above analysis, and waterproofing systems can be upgraded to include slab under drains and enhanced waterproofing elements. 8. Retaining wall backfill should be placed and compacted in accordance with the "Earthwork" section of this report. Backfll shall consist of soil with a very low expansion potential, granular, free draining material. SURFACE DRAINAGE Adequate drainage precautions at this site are imperative and will play a critical role on the future performance of the dwelling and improvements. Under no circumstances should water be allowed to pond against or adjacent to foundation walls, or tops of slopes. The ground surface surrounding proposed improvements should be relatively impervious in nature, and slope to drain away from the structure in all directions, with a minimum slope of 2% for a horizontal distance of 7 feet (where possible). Area drains or surface swales should then be provided to accommodate runoff and avoid any ponding of water. Any french drains, backdrains and/or slab underdrains shall not be lied to surface area drain systems. Roof gutters and downspouts shall be installed on the new and existing structures and tightlined to the area drain system. All drains should be kept clean and unclogged, including gutters and downspouts. Area drains should be kept free of debris to allow for proper drainage. Over watering can adversely affect site improvements and cause perched groundwater conditions. Irrigation should be limited to only the amount necessary to sustain plant life. Low flow irrigation devices as well as automatic rain shut -off devices should be installed to reduce over watering. Irrigation practices and maintenance of irrigation and drainage systems are an important component to the performance of onsite improvements. During periods of heavy rain, the performance of all drainage systems should be inspected. Problems such as gullying or pending should be corrected as soon as possible. Any leakage from sources such as water lines should also be repaired as soon as possible. In addition, irrigation of planter areas, lawns, or other vegetation, located adjacent to the foundation or exterior flat work improvements, should be strictly controlled or avoided. CONSTRUCTION OBSERVATION AND TESTING The recommendations provided in this report are based on subsurface conditions disclosed by our investigation of the project area. Interpolated subsurface conditions should be verified in the field during construction. The following items shall be conducted prior /during construction by a representative of Engineering Design Group in order to verify compliance with the geotechnical and civil engineering recommendations provided herein, as applicable. The project structural and geotechnical engineers may upgrade any condition as deemed necessary during the development of the proposed improvement(s). 1. Review of final approved structural plans prior to the start of work for compliance with geotechnical recommendations. 2. Attendance of a pre - grade /construction meeting prior to the start of work. 3. Testing of any fill placed, including retaining wall backfill and utility trenches. 4. Observation of footing excavations prior to steel placement and removal of excavation equipment. 5. Field observation of any "field change' condition involving soils. 6. Walk through of final drainage detailing prior to final approval. The project soils engineer may at their discretion deepen footings or locally recommend additional steel reinforcement to upgrade any condition as deemed necessary during site observations. Engineering Design Group shall, prior to the issuance of the certificate of occupancy, issue in writing that the above inspections have been conducted bya representative of theirfirm, and the design considerations of the project soils New Residence Page No. 8 599 Camino El Dorado, Encinitas, California Job No. 104714 -1 ENGINEERING DESIGN GROUP GEOrFGIW,-Jl. GML, STNUCTUWLL CCNSIRTANrS report have been met. The field inspection protocol specified herein is considered the minimum necessary for Engineering Design Group to have exercised "due diligence" in the soils engineering design aspect of this building. Engineering Design Group assumes no liability for structures constructed utilizing this report not meeting this protocol. Before commencement of grading the Engineering Design Group will require a separate contract for quality control observation and testing. Engineering Design Group requires a minimum of 48 hours notice to mobilize onsite for field observation and testing. MISCELLANEOUS It must be noted that no structure or slab should be expected to remain totally free of cracks and minor signs of cosmetic distress. The flexible nature of wood and steel structures allows them to respond to movements resulting from minor unavoidable settlement of fill or natural soils, the swelling of clay soils, or the motions induced from seismic activity. All of the above can induce movement that frequently results in cosmetic cracking of brittle wall surfaces, such as stucco or interior plaster or interior brittle slab finishes. Data for this report was derived from surface observations at the site, knowledge of local conditions, and a visual observation of the soils exposed in the exploratory test pits. The recommendations in this report are based on our experience in conjunction with the limited soils exposed at this site and neighboring sites. We believe that this information gives an acceptable degree of reliability for anticipating the behavior of the proposed structure; however, our recommendations are professional opinions and cannot control nature, nor can they assure the soils profiles beneath or adjacent to those observed. Therefore, no warranties of the accuracy of these recommendations, beyond the limits of the obtained data, is herein expressed or implied. This report is based on the investigation at the described site and on the specific anticipated construction as staled herein. If either of these conditions is changed, the results would also most likely change. Man -made or natural changes in the conditions of a property can occur over a period of lime. In addition, changes in requirements due to state of the art knowledge and /or legislation, are rapidly occurring. As a result, the findings of this report may become invalid due to these changes. Therefore, this report for the specific site, is subject to review and not considered valid after a period of one year, or if conditions as slated above are altered. It is the responsibility of the owner or his representative to ensure that the information in this report be incorporated into the plans and /or specifications and construction of the project. It is advisable that a contractor familiar with construction details typically used to deal with the local subsoil and seismic conditions, be retained to build the structure. If you have any questions regarding this report, or if we can be of further service, please do not hesitate to contact us. We hope the report provides you with necessary information to continue with the development of the project. 599 Camino El Dorado, Encinitas, California ENGINEERING DESIGN GROUP acarwNSU, CIM.

Various Aerial Photographs APPENDIX B General Earthwork and Grading Specifications 1.0 General Intent These specifications are presented as general procedures and recommendations for grading and earthwork to be utilized in conjunction with the approved grading plans. These general earthwork and grading specifications are a part of the recommendations contained in the geolechnical report and shall be superseded by the recommendations in the geotechnical report in the case of conflict. Evaluations performed by the consultant during the course of grading may result in new recommendations which could supersede these specifications or the recommendations of the geotechnical report. It shall be the responsibility of the contractor to read and understand these specifications, as well as the geotechnical report and approved grading plans. 2.0 Earthwork Observation and Testing Prior to commencement of grading, a qualified geotechnical consultant should be employed for the purpose of observing earthwork procedures and testing the fills for conformance with the recommendations of the geotechnical report and these specifications. It shall be the responsibility of the contractor to assist the consultant and keep him apprised of work schedules and changes, at least 24 hours in advance, so that he may schedule his personnel accordingly. No grading operations should be performed without the knowledge of the geotechnical consultant. The contractor shall not assume that the geotechnical consultant is aware of all grading operations. It shall be the sole responsibility of the contractor to provide adequate equipment and methods to accomplish the work in accordance with the applicable grading codes and agency ordinances, recommendations in the geotechnical report and the approved grading plans not withstanding the testing and observation of the geotechnical consultant If, in the opinion of the consultant, unsatisfactory conditions, such as unsuitable soil, poor moisture condition, inadequate compaction, adverse weather, etc., are resulting in a quality of work less than recommended in the geotechnical report and the specifications, the consultant will be empowered to reject the work and recommend that construction be slopped until the conditions are rectified. Maximum dry density tests used to evaluate the degree of compaction shouts be performed in general accordance with the latest version of the American Society for Testing and Materials test method ASTM D1557. 3.0 Preparations of Areas to be Filled 3.1 Clearing and Grubbing: Sufficient brush, vegetation, roots and all other deleterious material should be removed or properly disposed of in a method acceptable to the owner, design engineer, governing agencies and the geotechnical consultant. The geotechnical consultant should evaluate the extent of these removals depending on specific site conditions. In general, no more than 1 percent (by volume) of the fill material should consist of these materials and nesting of these materials should not be allowed. 3.2 Processing: The existing ground which has been evaluated by the geotechnical consultant to be satisfactory for support of fill, should be scarified to a minimum depth of 6 inches. Existing ground which is not satisfactory should be overexcavated as specified in the following section. Scarification should continue until the soils are broken down and free of large clay lumps or clods and until the working surface is reasonably uniform, flat, and free of uneven features which would inhibit uniform compaction. 3.3 Overexcavation: Soft, dry, organic -rich, spongy, highly fractured, or otherwise unsuitable ground, extending to such a depth that surface processing cannot adequately improve the condition, should be overexcavated down to competent ground, as evaluated by the geotechnical consultant. For purposes of determining quantities of materials overexcavated, a licensed land surveyor I civil engineer should be utilized. 3.4 Moisture Conditionino: Overexcavated and processed soils should be watered, dried back, blended and I or mixed, as necessary to attain a uniform moisture content near optimum. 3.5 Recompaction: Overexcavated and processed soils which have been properly mixed, screened of deleterious material and moisture - conditioned should be recompacted to a minimum relative compaction of 90 percent or as otherwise recommended by the geotechnical consultant. 3.6 Benching: Where fills are to be placed on ground with slopes steeper than 5:1 (horizontal to vertical), the ground should be stepped or benched. The lowest bench should be a minimum of 15 feel wide, at least 2 feel into competent material as evaluated by the geotechnical consultant. Other benches should be excavated into competent material as evaluated by the geotechnical consultant. Ground sloping flatter than 5:1 should be benched or otherwise overexcavaled when recommended by the geotechnical consultant. 3.7 Evaluation of Fill Areas: All areas to receive fill, including processed areas, removal areas and toe -of -fill benches, should be evaluated by the geotechnical consultant prior to fill placement. 4.0 Fill Material 4.1 General: Material to be placed as fill should be sufficiently free of organic matter and other deleterious substances, and should be evaluated by the geotechnical consultant prior to placement. Soils of poor gradation, expansion, or strength characteristics should be placed as recommended by the geotechnical consultant or mixed with other soils to achieve satisfactory fill material. 4.2 Oversize: Oversize material, defined as rock or other irreducible material with a maximum dimension of greater than 6 inches, should not be buried or placed in fills, unless the location, materials and disposal methods are specifically recommended by the geotechnical consultant. Oversize disposal operations should be such that nesting of oversize material does not occur, and such that the oversize material is completely surrounded by compacted or densified fill. Oversize material should not be placed within 10 feet vertically of finish grade, within 2 feet of future utilities or underground construction, or within 15 feet horizontally of slope faces, in accordance with the attached detail. 4.3 Import: If importing of rill material is required for grading, the import material should meet the requirements of Section 4.1. Sufficient time should be given to allow the geotechnical consultant to observe (and test, if necessary) the proposed import materials. 5.0 Fill Placement and Compaction 5.1 Fill Lifts: Fill material should be placed in areas prepared and previously evaluated to receive fill, in near - horizontal layers approximately 6 inches in compacted thickness. Each layer should be spread evenly and thoroughly mixed to attain uniformity of material and moisture throughout. 5.2 Moisture Conditioning: Fill soils should be watered, dried -back, blended and/or mixed. as necessary to attain a uniform moisture content near optimum. 5.3 Compaction of Fill: After each layer has been evenly spread, moisture conditioned and mixed, it should be uniformly compacted to no less than 90 percent of maximum dry density (unless otherwise specified). Compaction equipment should be adequately sized and be either specifically designed for soil compaction or of proven reliability, to efficiently achieve the specified degree and uniformity of compaction. 5.4 Fill Slopes: Compacting of slopes should tie accomplished in addition to normal compacting procedures, by backrolling of slopes with sheepsfoot rollers at increments of 3 to 4 feet in fill elevation gain, or by other methods producing satisfactory results. At the completion of grading, the relative compaction of fill out to the slope face would be at least 90 percent. 5.5 Compaction Testing: Field tests of the moisture content and degree of compaction of the fill soils should be performed at the consultant's discretion based on file dconditions encountered. In general, the tests should be taken at approximate intervals of 2 feet in vertical rise and/or 1,000 cubic yards of compacted fill soils. In addition to, on slope faces, as a guideline approximately one test should be taken for every 5,000 square feet of slope face and /or each 10 feet of vertical height of slope. 6.0 Subdrain Installation Subdrain systems, if recommended, should be installed in areas previously evaluated for suitability by the geotechnical consultant, to conform to the approximate alignment and details shown on the plans or herein. The subdrain location or materials should not be changed or modified unless recommended by the geotechnical consultant. The consultant however, may recommend changes in subdrain line orgrade depending on conditions encountered. All subdrains should be surveyed by a licensed land surveyor / civil engineer for line and grade after installation. Sufficient time shall be allowed for the survey, prior to commencement of filling over the subdrains. 7.0 Excavation Excavations and cut slopes should be evaluated by a representative of the geotechnical consultant (as necessary) during grading. If directed by the geotechnical consultant, further excavation, overexcavalion and refilling of cut areas and /or remedial grading of cut slopes (i.e. stability fills or slope buttresses) may be recommended. 8.0 Quantity Determination For purposes of determining quantities of materials excavated during grading and /or determining the limits of overexcavalion, a licensed land surveyor I civil engineer should be utilized.

Windrows should be staggered vertically (as depicted). 5) Rock should be placed in excavated trenches. Granular soil (S.E. greater than or equal to 30) should be flooded in the windrow to completely fill voids around and beneath rocks. APPENDIX C LABORATORY TESTING PROCEDURES Direct Shear Test: Direct shear tests are performed on remolded and /or relatively undisturbed samples which are soaked for a minimum of 24 hours prior to testing. After transferring the sample to the shearbox, and reloading, pore pressures are allowed to dissipated for a period of approximately 1 hour prior to application of shearing force. The samples are sheared in a motor- driven, strain controlled, direct-shear testing apparatus. After a travel of approximately 114 inch, the motor is stopped and the sample is allowed to 'relax- for approximately 15 minutes. Where applicable, the 'relaxed" and "peak' shear values are recorded. It is anticipated that, in a majority of samples tested, the 15 minutes relaxing of the sample is sufficient to allow dissipation of pore pressures set up due to application of the shearing force. The relaxed values are therefore judged to be good estimations of effective strength parameters. Expansion Index Tests: The expansion potential of representative samples is evaluated by the Expansion Index Test, U.B.C. Standard No. 29 -2. Specimens are molded under a given compactive energy to approximately the optimum moisture content and approximately 50 percent saturation. The prepared 1 -inch thick by 4 -inch diameter specimens are loaded to an equivalent 144 psf surcharge and are inundated with lap water for 24 hours or until volumetric equilibrium is reached. Classification Tests: Typical materials were subjected to mechanical grain -size analysis by wet sieving from U.S. Standard brass screens (ASTM D22 -65). Hydrometer analyses were performed where appreciable quantities of fines were encountered. The data was evaluated in determining the classification of the materials. The grain -size distribution curves are presented in lest data and the Unified Soil Classification is presented in both the test data and the boring logs.

CA 92075 Re: Proposed New Residence to be located at 599 Camino El Dorado, Encinitas, California Subject. Compaction Report INTRODUCTION In accordance with your request and authorization we have provided limited earthwork observation and compaction testing services during the rough grading at the above referenced site. The results of our quality control and compaction testing operations are summarized below. As we understand the proposed improvements onsite include a new single family residence. GRADING OPERATIONS The scope of grading operations addressed herein consists of excavation and compaction of sub - grade, placement and compaction of class II base at driveway apron and areas of street widening (approximately 8 feet) along Camino El Dorado, and a removal and recompaction in the area of the building. According to the project contractor the accessary unit and carport have been eliminated at this time and no testing was performed in these areas. Pavement subgrade is described as rust brown, slightly silty sands with some gravel and small cobbles, and generally possess expansion potential in low range. Class II base was utilized as base material below pavement finished surfaces at the right of way. Prior to recompaction soils were cleaned of vegetative and other debris and moisture conditioned. Soil was placed utilizing a wacker and remote vibratory roller. A removal and re- compaction was performed in the approximate area of the proposed building pad. Removals extended approximately 2 -3 feet below adjacent grade and extended to competent material. The limits of the building pad were removed and re- compacted 5 feet outside of the proposed building pad. The building pad area was established by project contractor. Subgrade was ripped 12 inches and moisture conditioned with a fire hose. Onsite soils were placed and re- compacted to approximate proposed pad elevation, approximately 1 foot higher than existing pad grade. Rough grading at the subject site was conducted during October 2010. Onsite soil was utilized as graded fill. Prior to re- compaction soils were cleaned of vegetation and other debris and moisture conditioned. Onsite soil consisted of a range of light brown to brown, slightly silty sands. Based upon our visual observation onsite soils possess potential for expansion in the low range. Soil was moisture conditioned with a fire hose and placed utilizing a dozer. ADDITIONAL RECOMMENDATIONS The contractor should pre -soak the foundations and slab subgrade to 2% over optimum to a depth of 18 inches below adjacent grade prior to the placement of capillary break and visqueen. FIELD AND LABORATORY TESTING Limited field density tests were performed in accordance with D2922 -96 (Nuclear Gauge Method). Our test results indicate that, in the locations tested, soils have been compacted to at least 90% relative compaction, as determined by ASTM D1557, (Procedure A). The reported test results are representative of the soil conditions at the locations tested. Our observation and field density testing methods are in accordance with normally accepted procedures. The accuracy of the relative compaction values are subject to the precision limitations of the ASTM test methods. The accuracy of the maximum dry density determination (ASTM D1557) is discussed in the 2003 Annual Book of ASTM Standards, Section 4, Volume 04.08, entitled, Soil and Rock; Building Stones. Variations of relative compaction values should be expected, laterally and vertically, from actual test locations. TESTING SUMMARY In general, it is our opinion, based on the placement procedure and the test data collected, the fill soils tested, at the locations tested, were compacted to a minimum of 90°/ relative compaction (based on ASTM D1557, Procedure A). If you have any questions regarding this report, or if we can be of further service, please do not hesitate to contact us. W e hope the report provides you with the necessary information to continue with the development of the project.
