Dear Mr. and Mrs. Hokanson: Southern California Soil and Testing, Inc. (SCS&T) has observed the recently completed excavation for the proposed garage at the subject site. Competent, native terrace deposits are exposed at pad grade throughout the excavation. These materials are as anticipated in the referenced soil investigation report, and are suitable for the support of the proposed structure, SCS&T also observed the foundation excavations for the proposed garage retaining walls. The foundation excavations conformed to SCS&T recommendations and project structural plans. SCS&T has observed the unshored temporary slopes around the garage excavation. The lower portions of these slopes expose cemented terrace deposits, while the upper portions expose loose slopewash deposits. The temporary slopes are generally suitable in their current condition. However, the uppermost 4 feet of the south slope, which exposes loose slopewash deposits, should be laid back at an inclination of about 1:1 (horizontal:vertical). The temporary shoring at the north side of the garage excavation will be removed to facilitate retaining wall construction. The temporary slope exposed by shoring removal should be laid back to generally match the adjacent temporary slopes to the east and west. Any loose or disturbed soil should be removed from the slope face. A wedge of compacted fill should be placed at the toe of the temporary slope to replace soils disturbed by shoring removal. A representative of SCS&T should observe the temporary slope after the work described above is completed to verify that no adverse soil conditions requiring mitigation are present. 6192804717 accounting 04:11:45 p.m. 04-15-2008 3/3 April 15,2008 Mr. &Mrs.Hokanson SCS&T No. 0811024-1 Proposed Hokanson Residence page 2 408 Chesterfield Dr., Encinitas, CA Should you have questions regarding this document, please contact us at your convenience. 4 Very t SO RNIA SOIL &TESTING, INC. a F?'0 GEO CC", C:i 9 W e '9 FUFCA��� #1938 Daniel r, RCE 36037 Mich Vice President Associa �^ � eying Geologist DBA:kv (2) Addressee (1) Attn: Ben Oliver, Inspector (1) Pacific Crest Development C 6192aO4717 accounting 04:11:04 p.m. 04-15-2008 113 `°"&TESTING.

Our services were performed between June 13 and July 8,2008. The grading was performed by Pacific Concrete Cutting of San Diego, California. To assist in determining the locations and elevations of our field density tests,we were provided with a grading plan prepared by Pasco Engineering dated November 6,2007,which defines the general extent of site grading. 1. PROJECT DESCRIPTION 1.1. SITE PREPARATION 1.1.1. Primary Equipment The primary equipment employed for the site mass grading operations included: 1 -Caterpillar Backhoe 1 -Water hose 1 - IR Vibratory sheep's foot roller 1 -hand tamper July t 1,2008 Mr.And Mrs. Nakanson SCS&T No. 0811024-2 Hokanson Residence Page 2 1.1.2. Clearing and Grubbing Site preparation began with the.demolition of the existing improvements and the clearing and grubbing of the existing vegetation and organic matter at the proposed development area. The material generated from these operations was exported from the site. 1.2. SITE GRADING The potentially compressible topsoil and loose terrace deposits were removed from the areas to receive fill and from beneath settlement-sensitive improvements. The bottoms of the removal areas typically exposed dense terrace deposits. The removals extended laterally 5 feet beyond the building envelope when possible. Following the removals,the exposed surface was scarified to a depth of 12 inches, moisture conditioned,and compacted. The excavated soil was placed as compacted fill. Fill was placed in 6 to 8-inch lifts, moisture conditioned to near optimum moisture content and compacted until field density tests indicated a minimum of 90%relative compaction. All references to optimum moisture and relative compaction in this report are based on the ASTM D 1557 laboratory test method. Compaction was achieved by means of a Ingersoll Rand Vibratory sheep's foot roller or hand tamper. This process continued until planned elevations were reached. 1.3. BASEMENT WALL BACKFILL The backfill material for the garage basement walls was placed in 6 to 8-inch lifts, moisture- conditioned and compacted to a minimum of 90 % compaction. Compaction was achieved primarily by means of a hand tamper. The basement wall backfill in-place density tests have been labeled "W13" and their approximate locations are noted on Plate 1. 2. FIELD OBSERVATIONS AND LABORATORY TESTS Field observations and density tests were performed by a representative of SCS&T during the grading operations at the locations shown on Plate 1. The density tests were performed according to ASTM D 6938(nuclear gauge)procedures. The results of these tests are shown on the attached plates. The accuracy of the in-situ density test locations and elevations is a function of the accuracy of the survey control provided by others than SCS&T representatives. Unless otherwise noted, their locations and elevations were determined by pacing and hand level methods and should be considered accurate only to the degree implied by the method used. As used herein,the term"observation"implies only that we observed the progress of work we were involved with,and performed field density tests which,in conjunction with our observations,were the C . Mr.And Mrs. Nokanson July 11.2008 Nokanson Residence SCS&T No. 0811024-2 Page 3 base for our opinion as to whether the work was performed in substantial conformance with the geotechnical recommendations and the requirements of the applicable agencies. Maximum dry density determinations were performed on representative samples of the soils used in the compacted fills according to ASTM D 1557. The results of these tests, presented on Plate 2, were used in conjunction with the field density tests to determine the degree of relative compaction of the compacted fill. 2.1, REMAINING WORK The following operations remain to be completed. It is recommended that field observations and relative compaction tests be performed during these operations to verify that these operations are being performed in accordance with job requirements and local grading ordinances. Removal and recompact of hardscape areas; Subgrade preparation for hardscape areas; Backfilling of retaining walls; Backfilling the underground utility trenches. 3. CONCLUSIONS Based on our field observations and the in-place density test results, it is our opinion that the building pad preparation and compaction were performed substantially in accordance with the recommendations contained in the referenced geotechnical report, the City of Encinitas Grading Ordinance, the Grading/improvement Plan Drawing Number 573-G, and the California Building Code. 4. LIMITATIONS This report covers only the services performed between June 13 and July 8,2008. Our opinions are based on our observations and the relative compaction test results and are limited by the scope of the work that we agreed to perform. Our work was performed in accordance with the currently accepted standard of practice and in such a manner as to provide a reasonable measure of the compliance of the grading and backfill operations with the project requirements. No warranty, express or implied, is made or intended with respect to the work that we have performed, and neither the performance of this work nor the submittal of this report should be construed as relieving the contractor of its responsibility to conform with the project requirements. ST . Mr. And Mrs,Hokanson July 11,2008 SCS&7 No.0811024-2 Hokanson Residence Page 4 Our work was generally performed on an "on-call" basis. Therefore, the in-place density tests performed by our field representative can only"be construed as representative of the areas tested as shown on the attached plates.

INTRODUCTION AND PROJECT DESCRIPTION This report presents the results of our soil investigation for the proposed addition to an existing residential structure located at 408 Chesterfield Drive in the City of Encinitas, California. The site location is shown on Figure No. 1. — It is our understanding that the subject project will consist of a second story and lateral additions to the existing structure. Construction will include increasing the existing basement area. The additions will be of wood-frame and masonry construction. New and existing shallow _ foundations are proposed to support new loads. To assist in the preparation of this report, we were provided with a topographic survey prepared by Pasco Engineering, dated May 15, 2005, and undated basement and first floor plans of unknown origin. 2. PROJECT SCOPE The investigation consisted of: surface reconnaissance, subsurface exploration, obtaining representative disturbed and undisturbed samples, laboratory testing, analysis of the field and _ laboratory data, and preparation of this report. More specifically, the intent of this analysis was to: a) Explore the subsurface conditions. b) Evaluate the engineering properties of the various strata that may influence the proposed development, including bearing capacities, expansion characteristics and settlement potentials. c) Evaluate the geotechnical suitability of existing footings to support new loads. d) Address potential construction conditions that may be encountered due to subsurface conditions, or groundwater, and provide recommendations concerning these conditions. e) Develop geotechnical engineering criteria for site preparation. C Mr. &Mrs. Jeff Hokanson November 14, 2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1R 408 Chesterfield Dr., Encinitas, CA Page 2 _ f) Recommend an'appropriate foundation system for the type of structure anticipated and develop geotechnical engineering design criteria for the recommended foundation system. 3. FINDINGS 3.1 SITE DESCRIPTION — The subject site is located at 408 Chesterfield Drive in the city of Encinitas, California. The rectangular-shaped site is bounded on the south by Chesterfield Drive, on the east by an alley, on the west by Cambridge Avenue and on the north by a residential development. The lot is presently occupied by a one and two-story, split-level, single-family residential structure. The garage portion of the building is partially underground. Exterior improvements include concrete — slabs, a deck, a spa and masonry walls. Topographically, the site consists primarily of a level pad. A descending slope about 6 feet in height exists in the southwestern corner of the lot. Existing vegetation consists of a grass lawn, small bushes and trees. 3.2 EXISTING FOOTING The existing basement wall footing was exposed in Pit No. 4. The footing is located 4 feet below grade, is 12 inches thick and extends 6 inches into medium dense terrace deposits. 3.3 SOIL DESCRIPTION The subject site is underlain by fill, slopewash and terrace deposits. Fill was encountered in all test pits except Test Pit No. 1. This material consists of brown, humid, loose, silty sand. The fill encountered in the test pits extends to depths ranging from about 6 inches to 4 feet below existing grade. However, deeper fills may exist under the southwestern corner of the site. Slopewash was encountered in Test Pit No. 1 to a depth of about 1'/2 feet. This material consists of brown, humid, loose, silty sand. The surficial soils are underlain by terrace deposits -- consisting of light brown tan and reddish brown, humid, loose to very dense, silty sand. 3.4 GROUNDWATER No groundwater was observed in the test pits. Seepage can occur after construction on a site, even where none was present before construction. This is often the result of an alteration in drainage patterns and an increase in irrigation water. Local seepage can be most effectively addressed on an individual basis if and when it occurs. C Mr. &Mrs. Jeff Hokanson November 14, 2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1 R 408 Chesterfield Dr., Encinitas, CA Page 3 4. CONCLUSIONS In general, no geotechnical conditions were encountered which would preclude the construction _ of the proposed addition as presently proposed, provided the recommendations presented herein are followed. _ The majority of the site is underlain by potentially compressible fill and native soils. As encountered in the test pits, these materials range in depth from about 1'/2 feet to 4 feet. These materials are unsuitable, in their present condition, for the support of settlement sensitive improvements. In order to mitigate this condition, it is recommended that new footings extend into terrace deposits. In addition, it is recommended that existing loose soils underlying settlement-sensitive improvements be removed and replaced as compacted fill. 5. RECOMMENDATIONS 5.1 GRADING 5.1.1 Site Preparation Site preparation should begin with the demolition of existing improvements from proposed building areas. The resulting debris as well as any existing vegetation and deleterious - matter should be disposed of properly. It is recommended that the loose fill and native soils underlying proposed settlement-sensitive improvements be removed and replaced as compacted fill. Based on our findings, maximum removal depths will be about 4 feet. However, deeper removals may be required in areas of the site not investigated. Minimum lateral removal limits should be 5 feet beyond the perimeter of the structure. No removals -- should extend beyond property lines. Excavated soils can be reused as compacted fill where necessary to meet planned final grades. The soils exposed in the bottom of the _ excavations should be scarified to a depth of 12 inches, watered thoroughly and compacted to at least 90 percent relative compaction. The maximum dry density and optimum moisture content for the determination of relative compaction should be determined in accordance with ASTM D-1557, Method A or C. All references to optimum moisture content and relative compaction in this report are based on this test method. Fill should be placed in 6- to 8-inch thick loose lifts and compacted to at least 90 percent relative compaction. 5.1.2 Surface Drainage The drainage around the proposed improvements should be designed to collect and direct surface water away from proposed improvements and the top of slopes toward appropriate drainage facilities. " Alrw.C f Mr. &Mrs. Jeff Hokanson Proposed Hokanson Residence Addition November 14, 2006 408 Chesterfield Dr., Encinitas, CA SCS&T No. 0611215-1 R Page 4 It is imperative that the drainage around the improvements be designed to collect and direct surface water away from the improvements and toward appropriate drainage devices. Rain gutters with downspouts that discharge runoff away from the structure into controlled drainage devices are recommended. The ground around the proposed improvements should be graded so that surface water flows rapidly away from the improvements without ponding. In general, we recommend that the ground adjacent to structures be sloped away at a gradient of at least 2 percent. Densely vegetated areas where runoff can be impaired should have a minimum gradient of at least 5 percent within the first 5 feet from the structure. _ Drainage patterns provided at the time of fine grading should be maintained throughout the life of the proposed improvements. Site irrigation should be limited to the minimum necessary to sustain landscape growth, and over-watering should be avoided. Should excessive irrigation, impaired drainage, or unusually high rainfall occur, zones of wet or saturated soil may develop. 5.1.3 Earthwork All earthwork and grading contemplated for site preparation should be accomplished in accordance with the attached Recommended Grading Specifications and Special Provisions. All special site preparation recommendations presented in the sections above supersede those in the standard Recommended Grading Specifications. Fill should be compacted to at least 90% relative compaction at or slightly over optimum moisture content. Utility trench backfill within 5 feet of the road bed surface should be compacted to a minimum of 90% relative compaction. The upper 12 inches of subgrade beneath paved areas should be compacted to 95% relative compaction. 5.2 FOUNDATIONS 5.2.1 General New and existing shallow foundations founded on competent terrace deposits may be utilized for the support of the proposed addition. The footings should have a minimum depth of 18 inches below lowest adjacent finish pad grade and a minimum width of 15 and 24 inches is recommended for continuous and isolated footings, respectively. A bearing capacity of 1500 pounds per square foot (psf) may be assumed for said footings. The bearing capacities may be increased by 1/3 when considering wind or seismic forces. C Mr. &Mrs. Jeff Hokanson November 14, 2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1 R 408 Chesterfield Dr., Encinitas, CA Page 5 5.2.2 Reinforcement Both exterior and interior continuous footings should be reinforced with at least two No. 5 bars positioned near the bottom of the footing and at least two No. 5 bars positioned near the top of the footing. This reinforcement is based on soil characteristics and is not intended to be in lieu of reinforcement necessary to satisfy structural considerations. 5.2.3 Site Seismicity A geologic hazard likely to affect the site is groundshaking as a result of movement along -- one of the main strands of the active fault zones mentioned above. As per the 2001 California Building Code (CBC), the following information is presented for the subject site. Seismic Zone 4: Z=0.40 Source Fault: Rose Canyon Fault Seismic Source Type: B Soil Profile Type: Sp Distance to Seismic Source: = 4.0 kilometers Near-Source Factor Na=1.1 Near-Source Factor N,=1.3 Probable groundshaking levels at the site could range from slight to strong depending on such factors as the magnitude of the seismic event and the distance to the epicenter. It is likely that the site will experience the effects of at least one moderate to large earthquake during the life of the structures. 5.2.4 Settlement Characteristics The anticipated total and/or differential settlements for the proposed addition may be considered to be within tolerable limits provided the recommendations presented in this report are followed. It should be recognized that minor cracks normally occur in concrete slabs and foundations due to shrinkage during curing or redistribution of stresses and some cracks may be anticipated. Such cracks are not necessarily an indication of excessive vertical movements. 5.2.5 Expansive Characteristics -- The prevailing foundation soils were judged to be nondetrimentally expansive. The recommendations contained in this report assume this condition. 5.2.2 Foundation Excavation Observation It is recommended that all foundation excavations be approved by a representative from SCSBT prior to forming or placement of reinforcing steel. Existing footings to support new C.. Mr. &Mrs. Jeff Hokanson November 14, 2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1 R 408 Chesterfield Dr., Encinitas, CA Page 6 loads should be observed during construction to ascertain that they are founded on competent soils. _ 5.3 SLABS-ON-GRADE Concrete slabs-on-grade should have a thickness of 5 inches and be reinforced with at least No. — 4 reinforcing bars placed at 18 inches on-center each way. Slab reinforcement should be placed approximately at mid-height of the slab and should extend at least 6 inches down into the footings. Slabs-on-grade should be underlain by a 4-inch thick blanket of clean, poorly -- graded, coarse sand (sand equivalent = 30 or greater) or crushed rock. This blanket should consist of no more than 20 percent and 10 percent passing the #100 and #200 sieves, respectively. Where moisture sensitive floor coverings are planned, vapor retardant should be placed over the sand layer. An additional 2 inches of sand should be placed over the vapor retardant. Typically, plastic is used as a vapor retardant. If plastic is used, a minimum 10-mil is — recommended. The plastic should comply with ASTM E 1745. Plastic installation should comply with ASTM E 1643. It is our understanding that the moisture protection layer described above will allow the transmission of 6 to 12 pounds of moisture per 1000 square feet per day through the slab under _ normal conditions. Moisture emissions may vary widely depending upon factors such as concrete type and subgrade moisture conditions. If this amount of moisture is excessive, additional recommendations will be provided by this office. It is recommended that moisture emission tests be performed prior to the placement of floor coverings to ascertain whether moisture emission values are within the manufacturer's specifications. In addition, over-watering should be avoided, and good site drainage should be established and maintained to prevent the build-up of excess sub-slab moisture. 5.4 EARTH RETAINING WALLS 5.4.1 Foundations The recommendations provided in the foundation section of this report are also applicable to earth retaining structures. -- 5.4.2 Passive Pressure The passive pressure for the prevailing soil conditions may be considered to be 350 psf per foot of depth. This pressure may be increased 1/3 for seismic loading. The coefficient of friction for concrete to soil may be assumed to be 0.30 for the resistance to lateral movement. When combining frictional and passive resistance, the friction should be SL — Mr. &Mrs. Jeff Hokanson November 14, 2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1R 408 Chesterfield Dr., Encinitas, CA Page 7 reduced by 1/3. The upper 12 inches of soil should not be considered when calculating passive pressures for exterior walls. 5.4.3 Active Pressure The active soil pressure for the design of unrestrained earth retaining structures with level backfills may be assumed to be equivalent to the pressure of a fluid weighing 38 pcf. For restrained walls, an equivalent fluid pressure of 58 pcf may be assumed. These pressures do not consider any other surcharge loads. If any are anticipated, this office should be contacted for the necessary increase in soil pressure. These values assume a granular and drained backfill condition. Waterproofing specifications and details should be provided by the project architect. A typical wall subdrain detail is provided on the attached Plate No. 13. 5.4.4 Factor of Safety The above values, with the exception of the allowable bearing pressure, do not include a factor of safety. Appropriate factors of safety should be incorporated into the design to prevent the walls from overturning and sliding. 6. LIMITATIONS 6.1 REVIEW, OBSERVATION AND TESTING The recommendations presented in this report are contingent upon our review of final plans and specifications. Such plans and specifications should be made available to the geotechnical engineer and engineering geologist so that they may review and verify their compliance with this report and with Appendix Chapter 33 of the California Building Code. It is recommended that SCS&T be retained to provide continuous soil engineering services during the earthwork operations. This is to verify compliance with the design concepts, specifications or recommendations and to allow design changes in the event that subsurface conditions differ from those anticipated prior to start of construction. 6.2 UNIFORMITY OF CONDITIONS The recommendations and opinions expressed in this report reflect our best estimate of the project requirements based on an evaluation of the subsurface soil conditions encountered at the subsurface exploration locations and on the assumption that the soil conditions do not deviate appreciably from those encountered. It should be recognized that the performance of the foundations and/or cut and fill slopes may be influenced by undisclosed or unforeseen variations in the soil conditions that may occur in the intermediate and unexplored areas. Any unusual conditions not covered in this report that may be encountered during site development C Mr. &Mrs. Jeff Hokanson . 06 20 ,14 November Proposed Hokanson Residence Addition SCS&T No 0 r 14, 20 R 408 Chesterfield Dr., Encinitas, CA Page 8 should be brought to the attention of the geotechnical engineer so that he may make modifications if necessary. 6.3 CHANGE IN SCOPE This office should be advised of any changes in the project scope or proposed site grading so that we may'determine if the recommendations contained herein are appropriate. This should be verified in writing or modified by a written addendum. Disturbed samples of typical and representative soils were obtained and returned to the laboratory for testing. 6.4 TIME LIMITATIONS The findings of this report are valid as of this date. Changes in the condition of a property can, however, occur with the passage of time, whether they are due to natural processes or the work of man on this or adjacent properties. In addition, changes in the standards-of-practice and/or government codes may occur. Due to such changes, the findings of this report may be invalidated wholly or in part by changes beyond our control. Therefore, this report should not be relied upon after a period of two years without a review by us verifying the suitability of the _ conclusions and recommendations. 6.5 PROFESSIONAL STANDARD. In the performance of our professional services, we comply with that level of care and skill ordinarily exercised by members of our profession currently practicing under similar conditions and in the same locality. The client recognizes that subsurface conditions may vary from those encountered at the locations where our borings, surveys, and explorations are made, and that our data, interpretations, and recommendations be based solely on the information obtained by us. We will be responsible for those data, interpretations, and recommendations, but"shall not be responsible for the interpretations by others of the information developed. Our services consist of professional consultation and observation only, and no warranty of any kind whatsoever, express or implied, is made or intended in connection with the work performed or to be performed by us, or by our proposal for consulting or other services, or by our furnishing of oral or written reports or findings. 7. FIELD EXPLORATION Four test pits were excavated on October 26, 2006 at the locations indicated on Plate No. 1. The fieldwork was conducted under the observation of our engineering personnel. r C. Mr. &Mrs. Jeff Hokanson November 14, 2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1 R 408 Chesterfield Dr., Encinitas, CA Page 9 The test pits were carefully logged when made. These logs are presented on Plate Nos. 3 through 6. The soils are described in accordance with the Unified Soil Classification System as illustrated on the attached simplified chart on Plate No. 2. In addition, a verbal textural description, the wet color, the apparent moisture and the density or consistency are provided. The density of granular soils is given as very loose, loose, medium dense, dense or very dense. The consistency of silts or clays is given as very soft, soft, medium stiff, stiff, very stiff, or hard. Disturbed and "undisturbed" samples of typical and representative soils were obtained and -- returned to the laboratory for testing. 8. LABORATORY TESTING Laboratory tests were performed in accordance with the generally accepted American Society for Testing and Materials (ASTM) test methods or suggested procedures. A brief description of the tests performed is presented below: a) CLASSIFICATION: Field classifications were verified in the laboratory by visual examination. The final soil classifications are in accordance with the Unified Soil Classification System. -- b) MOISTURE-DENSITY: In-place moisture contents and dry densities were determined for representative soil samples. This information was an aid to classification and permitted recognition of variations in material consistency with depth. The dry unit — weight is determined in pounds per cubic foot, and the in-place moisture content is determined as a percentage of the soil's dry weight. The results are summarized in the pit logs. c) GRAIN SIZE DISTRIBUTION: The grain size distribution was determined for representative samples of the native soils in accordance with ASTM D 422. The results _ of these tests are presented on Plate No. 7. d) COMPACTION TEST: The maximum dry density and optimum moisture content of typical soils were determined in the laboratory in accordance with ASTM Standard Test '-' D 1557, Method A. The results of these tests are presented herein. — Sample Description Maximum Optimum Density Moisture _ P2 @ 0-25 Brown Silty Sand 123.0 8.3 — r C Mr. &Mrs. Jeff Hokanson November 14, 2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1 R 408 Chesterfield Dr., Encinitas, CA Page 10 _ e) DIRECT SHEAR TEST: A direct shear test was performed in accordance with ASTM D 3080. The shear stress was applied at a constant rate of strain of approximately 0.02 inch per minute. The results of these tests are presented on the attached Plate No. 8. "r f) SINGLE POINT CONSOLIDATION TESTS: Single point consolidation tests were performed on selected "undisturbed" samples. The consolidation apparatus was designed to accommodate a 1-inch high by 2.375-inch or 2.500-inch diameter soil sample laterally confined by a brass ring. Porous stones were placed in contact with the top and bottom of the sample to permit the addition or release of pore fluid during o testing. Selected loads were applied to the samples and the resulting deformations were recorded. The percent consolidation is reported as the ratio of the amount of vertical compression to the original sample height. The test samples were inundated to determine their behavior under the anticipated loads as soil moisture increases. The results of these tests are presented on Plate No. 9.

GRADING RECOMMENDATIONS PROPOSED HOKANSON RESIDENCE ADDITION 408 CHESTERFIELD DRIVE ENCINITAS, CALIFORNIA RECOMMENDED GRADING SPECIFICATIONS - GENERAL PROVISIONS GENERAL INTENT The intent of these specifications is to establish procedures for clearing, compacting natural ground, preparing areas to be filled, and placing and compacting fill soils to the lines and grades shown on the accepted plans. The recommendations contained in the accompanying report and/or the attached special provisions are a part of the Recommended Grading Specifications and shall supersede the provisions contained hereinafter in the -case of conflict. These specifications shall only be used in conjunction with the geotechnical report for which they are a part. No deviation from these specifications will be allowed, except where specified in the geotechnical report or in other written communication signed by the Geotechnical Engineer. OBSERVATION AND TESTING SCS&T shall be retained as the Geotechnical Engineer to observe and test the earthwork in accordance with these specifications. It will be necessary that the Geotechnical Engineer or his representative provide adequate observation so that he may provide his opinion as to whether or not the work was accomplished as specified. It shall be the responsibility of the contractor to -' assist the Geotechnical Engineer and to keep him appraised of work schedules, changes and new information and data so that he may provided these opinions. In the event that any _ unusual conditions not covered by the special provisions or preliminary geotechnical report are encountered during the grading operations. The Geotechnical Engineer shall be contacted for further recommendations. If, in the opinion of the Geotechnical Engineer, substandard conditions are encountered, such as questionable or unsuitable soil, unacceptable moisture content, inadequate compaction, "'- adverse weather, etc.; construction should be stopped until the conditions are remedied or corrected or he shall recommended rejection of this work. C , Mr. &Mrs.Jeff Hokanson November 14,2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1 R 408 Chesterfield Dr., Enciniats, CA Page 2 �- Tests used to determine the degree of compaction should be performed in accordance with the following American Society for Testing and Materials test methods: Maximum Density &Optimum Moisture Content- ASTM D 1557 Density of Soil In-Place - ASTM D 1556 or ASTM D 2922 All densities shall be expressed in terms of Relative Compaction as determined by the foregoing ASTM testing procedures. -' PREPARATION OF AREAS TO RECEIVE FILL All vegetation, brush and debris derived from clearing operations shall be removed, and legally ^' disposed of. All areas disturbed by site grading should be left in a neat and finished appearance, free from unsightly debris. After clearing or benching the natural ground, the areas to be filled shall be scarified to a depth of 6 inches, brought to the proper moisture content, compacted and tested for the specified minimum degree of compaction. All loose soils in excess of 6 inches thick should be removed to firm natural ground, which is defined as natural soils which possesses an in-situ density of at least 90 percent of its maximum dry density. When the slope of the natural ground receiving fill exceeds 20 percent (5 horizontal units to 1 vertical unit), the original ground shall be stepped or benched. Benches shall be cut into firm competent formational soils. The lower bench shall be at least 10 feet wide or 1-1/2 times the equipment width, whichever is greater, and shall be sloped back into the hillside at a gradient of not less than two percent. All other benches should be at least 6 feet wide. The horizontal portion of each bench shall be compacted prior to receiving fill as specified herein for compacted natural ground. Ground slopes flatter than 20 percent shall be benched when considered necessary by the Geotechnical Engineer. Any abandoned buried structures encountered during grading operations must be totally removed. All underground utilities to be abandoned beneath any proposed structure should be removed from within 10 feet of the structure and properly capped off. The resulting depressions from the above-described procedure should be backfilled with acceptable soil that is compacted to the requirements of the Geotechnical Engineer. This includes, but is not limited to, septic tanks, fuel tanks, sewer lines or leach lines, storm drains and water lines. Any buried structures — or utilities no to be abandoned should be brought to the attention of the Geotechnical Engineer so that he may determine if any special recommendation will be necessary. All water wells, which will be abandoned, should be backfilled and capped in accordance to the requirements set forth by the Geotechnical Engineer. The top of the cap should be at least 4 feet below finish c Mr. & Mrs.Jeff Hokanson November 14,2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1 R 408 Chesterfield Dr., Enciniats, CA Page 3 grade or 3 feet below the bottom of footing whichever is greater. The type of cap will depend on the diameter of the well and should be determined by the Geotechnical Engineer and/or a — qualified Structural Engineer. FILL MATERIAL Materials to be placed in the fill shall be approved by the Geotechnical Engineer and shall be free of vegetable matter and other deleterious substances. Granular soil shall contain sufficient fine material to fill the voids. The definition and disposition of oversized rocks and expansive or detrimental soils are covered in the geotechnical report or Special Provisions. Expansive soils, soils of poor gradation, or soils with low strength characteristics may be thoroughly mixed with other soils to provide satisfactory fill material, but only with the explicit consent of the Geotechnical Engineer. Any import material shall be approved by the Geotechnical Engineer before being brought to the site. PLACING AND COMPACTION OF FILL Approved fill material shall be placed in areas prepared to receive fill in layers not to exceed 6 inches in compacted thickness. Each layer shall 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. Each layer shall be uniformly compacted to the specified minimum degree of compaction with equipment of adequate size to economically compact the layer. Compaction equipment should either be specifically designed for soil compaction or of proven reliability. The minimum degree of compaction to be achieved is specified in either the Special Provisions or -- the recommendations contained in the preliminary geotechnical investigation report. When the structural fill material includes rocks, no rocks will be allowed to nest and all voids must be carefully filled with soil such that the minimum degree of compaction recommended in the Special Provisions is achieved. The maximum size and spacing of rock permitted in structural fills and in non-structural fills is discussed in the geotechnical report, when applicable. Field observation and compaction tests to estimate the degree of compaction of the fill will be taken by the Geotechnical Engineer or his representative. The location and frequency of the tests shall be at the Geotechnical Engineer's discretion. When the compaction test indicates that a particular layer is at less than the required degree of compaction, the layer shall be reworked to the satisfaction of the Geotechnical Engineer and until the desired relative compaction has been obtained. C Mr. & Mrs.Jeff Hokanson November 14,2006 -- Proposed Hokanson Residence Addition SCS&T No. 06112R 408 Chesterfield Dr., Enciniats, CA Paage ge 4 -- Fill slopes shall be compacted by means of sheepsfoot rollers or other suitable equipment. Compaction by sheepsfoot roller shall be at vertical intervals of not greater than four feet. In addition, fill slopes at a ratio of two horizontal to one vertical or flatter, should be trackrolled. Steeper fill slopes shall be over-built and cutback to finish contours after the slope has been constructed. Slope compaction operations shall result in all fill material six or more inches inward from the finished face of the slope having a relative compaction of at least 90 percent of maximum dry density or the degree of compaction specified in the Special Provisions section of this specification. The compaction operation on the slopes shall be continued until the Geotechnical Engineer is of the opinion that the slopes will be surficially stable. Density tests in the slopes will be made by the Geotechnical Engineer during construction of the slopes to determine if the required compaction is being achieved. Where failing tests occur or other field problems arise, the Contractor will be notified that day of such conditions by written communication from the Geotechnical Engineer or his representative in the form of a daily field report. If the method of achieving the required slope compaction selected by the Contractor fails to produce the necessary results, the Contractor shall rework or rebuild such slopes until the required degree of compaction is obtained, at no cost to the Owner or Geotechnical Engineer. CUT SLOPES The Engineering Geologist shall inspect cut slopes excavated in rock or lithified formational material during the grading operations at intervals determined at his discretion. If any conditions not anticipated in the preliminary report such as perched water, seepage, lenticular or confined strata of a potentially adverse nature, unfavorably inclined bedding, joints or fault planes are encountered during grading, these conditions shall be analyzed by the Engineering Geologist and Soil Engineer to determine if mitigating measures are necessary. Unless otherwise specified in the geotechnical report, no cut slopes shall be excavated higher or steeper than the allowed by the ordinances of the controlling governmental agency. ENGINEERING OBSERVATION Field observation by the Geotechnical Engineer or his representative shall be made during the filling and compaction operations so that he can express his opinion regarding the conformance of the grading with acceptable standards of practice. Neither the presence of the Geotechnical Engineer or his representative or the observation and testing shall not release the Grading Contractor from his duty to compact all fill material to the specified degree of compaction. Mr. &Mrs. Jeff Hokanson November 14,2006 Proposed Hokanson Residence Addition SCS&T No. 0611215-1 R 408 Chesterfield Dr., Enciniats, CA Page 5 SEASON LIMITS Fill shall not be placed during unfavorable weather conditions. When work is interrupted by heavy rain, filling operations shall not be resumed until the proper moisture content and density of the fill materials can be achieved. Damaged site conditions resulting from weather or acts of God shall be repaired before acceptance of work. RECOMMENDED GRADING SPECIFICATIONS - SPECIAL PROVISIONS RELATIVE COMPACTION: The minimum degree of compaction to be obtained in compacted natural ground, compacted fill, and compacted backfill shall be at least 90 percent. For street -- and parking lot subgrade, the upper six inches should be compacted to at least 95 percent relative compaction. EXPANSIVE SOILS: Detrimentally expansive soil is defined as clayey soil which has an expansion index of 50 or greater when tested in accordance with the Uniform Building Code Standard 29-C. OVERSIZED MATERIAL: Oversized fill material is generally defined herein as rocks or lumps _ of soil over 6 inches in diameter. Oversized materials should not be placed in fill unless recommendations of placement of such material is provided by the geotechnical engineer. At least 40 percent of the fill soils shall pass through a No. 4 U.S. Standard Sieve. TRANSITION LOTS: Where transitions between cut and fill occur within the proposed building pad, the cut portion should be undercut a minimum of one foot below the base of the proposed footings and recompacted as structural backf ill. In certain cases that would be addressed in the geotechnical report, special footing reinforcement or a combination of special footing reinforcement and undercutting may be required.

HYDROLOGY This existing project site consists of an existing single family residence, patio areas, and a driveway. The proposed grading for this project will be for the construction of a new single family residence, patio areas, and a driveway. No drainage patterns will be significantly altered as a result of the grading. Runoff will continue to flow from east to west as it does in the current condition. HYDRAULICS The existing topography and drainage structures are adequate to convey and contain Qioo from the rest of the site as they did prior to the proposed work. Based on the discussion in this letter it is the professional opinion of Pasco Engineering, Inc. that the existing drainage system on the corresponding Grading Plan will function to adequately intercept, contain and convey flow from a 100 year storm to the appropriate points of discharge.

Dear Mr. And Mrs. Hokanson: In accordance with your request, this report has been prepared to present the results of field observations and tests performed during the grading for the proposed residence at 408 Chesterfield Drive in Encinitas,California. Our services were performed between June 13 and July 8,2008. The grading was performed by Pacific Concrete Cutting of San Diego, California. To assist in determining the locations and elevations of our field density tests,we were provided with a grading plan prepared by Pasco Engineering dated November 6,2007,which defines the general extent of site grading. 1. PROJECT DESCRIPTION 1.1. SITE PREPARATION 1.1.1. Primary Equipment The primary equipment employed for the site mass grading operations included: 1 —Caterpillar Backhoe 1 —Water hose 1 — IR Vibratory sheep's foot roller 1 —hand tamper Mr.And Mrs. Hokanson July 11,2008 H SCS&T Na. OBt 10242 okanson Residence Page 2 1.1.2. Clearing and Grubbing Site preparation began with the.demolition of the existing improvements and the clearing and grubbing of the existing vegetation and organic matter at the proposed development area. The material generated from these operations was exported from the site. 1.2. SITE GRADING The potentially compressible topsoil and loose terrace deposits were removed from the areas to receive fill and from beneath settlement-sensitive improvements. The bottoms of the removal areas typically exposed dense terrace deposits. The removals extended laterally 5 feet beyond the building envelope when possible. Following the removals,the exposed surface was scarified to a depth of 12 inches, moisture conditioned,and compacted. The excavated soil was placed as compacted fill. Fill was placed in 6 to 8-inch lifts, moisture conditioned to near optimum moisture content and compacted until field density tests indicated a minimum of 90%relative compaction. All references to optimum moisture and relative compaction in this report are based on the ASTM D 1557 laboratory test method. Compaction was achieved by means of a Ingersoll Rand Vibratory sheep's foot roller or hand tamper. This process continued until planned elevations were reached. 1.3. BASEMENT WALL BACKFILL The backfill material for the garage basement walls was placed in 6 to 8-inch lifts, moisture- conditioned and compacted to a minimum of 90 % compaction. Compaction was achieved primarily by means of a hand tamper. The basement wall backfill in-place density tests have been labeled "W13"and their approximate locations are noted on Plate 1. 2. FIELD OBSERVATIONS AND LA13ORATORY TESTS Field observations and density tests were performed by a representative of SCS&T during the grading operations at the locations shown on Plate 1. The density tests were performed according to ASTM D 6938(nuclear gauge)procedures. The results of these tests are shown on the attached plates. The accuracy of the in-situ density test locations and elevations is a function of the accuracy of the survey control provided by others than SCS&T representatives. Unless otherwise noted, their locations and elevations were determined by pacing and hand level methods and should be considered accurate only to the degree implied by the method used. As used herein,the term"observation"implies only that we observed the progress of work we were involved with,and performed field density tests which,in conjunction with our observations,were the Mr.And Mrs. Nokanson July 11,2008 Nokanson Residence SCS&T No, 08 11024-2 Page 3 base for our opinion as to whether the work was performed in substantial conformance with the geotechnical recommendations and the requirements of the applicable agencies. Maximum dry density determinations were performed on representative samples of the soils used in the compacted fills according to ASTM D 1557, The results of these tests, presented on Plate 2, were used in conjunction with the field density tests to determine the degree of relative compaction of the compacted fill. 2.1. REMAINING WORK The following operations remain to be completed. It is recommended that field observations and relative compaction tests be performed during these operations to verify that these operations are being performed in accordance with job requirements and local grading ordinances. Removal and recompact of hardscape areas; Subgrade preparation for hardscape areas; Backfilling of retaining walls; Backfilling the underground utility trenches. 3. CONCLUSIONS Based on our field observations and the in-place density test results, it is our opinion that the building pad preparation and compaction were performed substantially in accordance with the recommendations contained in the referenced geotechnical report, the City of Encinitas Grading Ordinance, the Grading/Improvement plan Drawing Number 573-G, and the California Building Code. 4. LIMITATIONS This report covers only the services performed between June 13 and July 8,2008. Our opinions are based on our observations and the relative compaction test results and are limited by the scope of the work that we agreed to perform. Our work was performed in accordance with the currently accepted standard of practice and in such a manner as to provide a reasonable measure of the compliance of the grading and backfill operations with the project requirements. No warranty, express or implied, is made or intended with respect to the work that we have performed, and neither the performance of this work nor the submittal of this report should be construed as relieving the contractor of its responsibility to conform with the project requirements. ST . Mr. And Mrs. Hokanson July 11,2008 Hokanson Residence SCS&T No.0811024-2 Page 4 Our work was generally performed on an "on-call" basis. Therefore, the in-place density tests performed by our field representative can only be construed as representative of the areas tested as shown on the attached plates.
