The field work was performed on January 30, 1990, by our Field Geologist. It is our understanding that the existing structure will be removed and that the site is being developed to receive a new two unit condominium structure and associated improvements. The structure is to be a maximum of two stories in height and will be constructed of standard- type building materials. Our investigation revealed that the site is underlain by dense natural- ground materials (terrace deposits) with approximately 2 feet of fill and topsoil at the surface of the site. In general, the surficial soils are loose, and as part of site preparation, we recommend that at least the upper 2 feet of surface soils be removed and recompacted to provide a more uniform, firm soil base for the proposed structure and improvements. In our opinion, if the conclusions and recommendations presented in this report are implemented during site preparation, the site will be suited for the proposed structure and improvements. This opportunity to be of service is sincerely appreciated. Should you have any questions concerning the following report, please do not hesitate to contact us. Reference to our Job No. 90-5706 will expedite response to your inquiries. Respectfully submitted, GEOTECHNICAL EXPLORATION, INC. X Werner R.

I. SCOPE OF WORK It is our understanding, based on communications with Mr. Travis Deal, that the site is intended for the construction of a two-story, two unit condominium structure and associated improvements. The existing structure is to be removed and the site will be graded to remove all vegetation and rework the. loose surface soils. With the above in mind, the Scope of Work is briefly outlined as follows: 1. Identify and classify the surface and subsurface soils to depths, in conformance with the Unified Soil Classification System (refer to Appendix A). 2. Recommend site preparation procedures. 3. Recommend the allowable bearing pressure for the existing soils. U. Estimate the anticipated settlement of the existing soils under the proposed structural loads. 5. Recommend foundation design information and provide active and passive earth pressures to be utilized in design of any proposed retaining walls and foundation structures.

SITE DESCRIPTION The property is known as: Assessor's Parcel No. 204-122-12, in the County of San Diego, State of California. The site, consisting of approximately 0.10 acre, is located at Chestnut Avenue, in the City of Carlsbad. The property is bordered on the north and west by developed residential properties, on the south by Chestnut Avenue and on the east by Garfield Street. Existing structures on the site consist of a single-story duplex structure with adjacent fences and concrete walkways. Vegetation on the site consists primarily of some weeds, grass, shrubbery and several large trees. The property is relatively level with a gentle slope to the west. The property is at an elevation of approximately 59 feet above mean sea level (MSL) . Survey information concerning actual elevations across the site was not available at the time of this investigation. III. FIELD INVESTIGATION Three hand-excavated test pits were placed on the site, specifically in areas where the new structure and improvements may be located and where access allowed. The handpits were logged by our Field Geologist, and samples were taken of the predominant soils throughout the field operation. Handpit logs have been prepared on the basis of our observations, and the results have been summarized on Figure No. II. The predominant soils have been classified in conformance with the Unified Soil Classification System (refer to Appendix A). CD ID I I I I I I I I I I I I I I I I I I I Proposed Two Unit Condominium Project Job No. 90-5706 Carlsbad, California Page 3 IV. DESCRIPTION OF SOILS r In general, the subject site is underlain by dense natural ground materials (terrace deposits) with approximately 2 feet of fill and topsoil at the surface of the site. The surficial soils (the upper 2 feet) were found to be loose, while the soils below 2 feet were generally medium dense to dense. The fill and topsoils consist of red-brown, silty, fine to medium sand with abundant roots. The terrace deposits consist of orange-brown, fine to medium sand with some silt and roots. Based on our experience, these soils are considered to have a very low expansion potential, with an expansion index of less than 20. V. GROUNDWATER No groundwater problems were encountered during the course of our field investigation and we do not expect groundwater problems to develop in the future — if the property is developed as presently designed and proper drainage is provided. It should be kept in mind, however, that any required grading operations may change surface drainage patterns and/or reduce permeabilities due to the densification of compacted soils. Such changes of surface and subsurface hydrologic conditions, plus irrigation of landscaping or significant increases in rainfall, may result in the appearance of minor amounts of surface or near-surface water at locations where none existed previously. The damage from such water is expected to be minor and cosmetic in nature, if good positive drainage is implemented at the completion of construction. Corrective action should be taken on a site-specific basis if, and when, it becomes necessary. VI. LABORATORY TESTS AND SOIL INFORMATION Laboratory tests were performed on the disturbed soil samples in order to evaluate their physical and mechanical properties and their ability to support the proposed structure. The following tests were conducted on the sampled soils: I I I I I I I I I I I I I I I I I I I Proposed Two Unit Condominium Project Job No. 90-5706 Carlsbad, California Page 4 1. Moisture/Density Relations (ASTM D1557-78, Method A) 2. Moisture Content (ASTM D2216-80) 3. Mechanical Analysis (ASTM D422-72) The relationship between the moisture and relative compaction of soil samples gives qualitative information regarding soil strength character- istics and soil conditions to be anticipated during any future grading operation. The mechanical analysis was used to aid in the classification of the soils according to the Unified Soil Classification System. Our experience indicates that the on-site sands have a very low expansion potential with an expansion index of less than 20. Based upon the above laboratory test data, observations of the primary soil types on the project, and our previous experience with laboratory testing of similar soils, our Ceotechnical Engineer has assigned conservative values for friction angle and cohesion to those soils which will have significant lateral support or bearing functions on the project. These values are presented in Figure No. Ill and have been utilized in recommending the allowable bearing value as well as the active and passive earth pressures for wall and footing designs. VII. CONCLUSIONS AND RECOMMENDATIONS The following conclusions and recommendations are based upon the practical field investigation conducted by our firm, and resulting laboratory tests, in conjunction with our knowledge and experience with the soils in the City of Carlsbad. dD ID I I I I I I I I I I I I I I I I I I I Proposed Two Unit Condominium Project Job No. 90-5706 Carlsbad, California Page 5 Our investigation revealed that the entire site is underlain by dense natural-ground materials (terrace deposits) with approximately 2 feet of fill and topsoil at the surface of the site. In general, the surficial soils are loose and, as part of the site preparation, we recommend that they be removed down to dense soils, but no less than 2 feet over the entire site be recompacted to provide a more uniform, firm soil base for the proposed structure and improvements. A. Preparation of Soils for Site Development 1. The existing structure, debris and vegetation observed on the site must be removed prior to the preparation of building pads and/or areas to receive structural improvements. This includes all roots from the existing trees that may extend under the proposed structure and improvements. Large roots have been known to cause significant damage to foundations. 2. To provide a more uniform, firm soil base for the proposed structure and improvements, all surface soils should be excavated to a depth of at least 2 feet, or as per the direction of our field technician. The bottom of the excavation shall be scarified, moisture conditioned, and properly recompacted. The excavated soils should be cleaned of any debris and deleterious materials, properly watered to approximately optimum moisture content , and compacted to at least 90 percent of Maximum Dry Density in accordance with ASTM D1557 standards. Any areas to receive new fill or that will support rigid improvements or proposed retaining structures should be prepared in a like manner. 3. No uncontrolled fill soils shall remain on the site after completion of any future site work. In the event that temporary ramps or pads are constructed of uncontrolled fill soils during the grading operation, the loose fill soils shall be removed and/or recompacted prior to completion of the grading operation. <JD HO I I I I I I I I I I I I I I I I I I I Proposed Two Unit Condominium Project Job No. 90-5706 Carlsbad, California Pages 4. Any buried objects which might be discovered on the site shall be removed and the excavation shall be properly backfilled with approved on-site or imported fill soils, and shall then be compacted to at least 90 percent of Maximum Dry Density. 5. Any backfill soils placed in utility trenches or behind retaining walls which support structures and other improvements (such as patios, sidewalks, driveways, pavements, etc.) shall be compacted to at least 90 percent of Maximum Dry Density. B. Design Parameters for Foundations and Retaining Walls 6. The recommended allowable soil bearing value for design of foundations for the proposed structure is 2-,000> pounds per square foot. This load-bearing value may be utilized in the design of continuous foundations and spread footings when founded a minimum of 18; inches::; into the firm natural ground or properly compacted fill, measured from the lowest adjacent grade at the time of foundation construction. This load-bearing value may be increased one-third for design loads that include wind or seismic analysis. If imported soils are required to bring the site to grade, the imported soils should be nonexpansive and be obtained from an approved off-site borrow area. Based upon our laboratory test results and our experience with the soil types on the subject site, the underlying native materials and all properly compacted fill should experience differential settlement in the magnitude of less than 1/2-inch in 25 feet, under a structural load of 2,000 pounds per square foot. 7. Due to numerous reasons, footings and slabs occasionally crack, causing ceramic tiles or other brittle floor coverings to become damaged. Footings and slabs should therefore contain at least a nominal amount of reinforcing steel to reduce the separation of cracks, should they occur. OD 10 I I I I I I I I I I I I I I I I I I I Proposed Two Unit Condominium Project Job No. 90-5706 Carlsbad, California Page 7 7.1 A minimum of steel for continuous footings should include at least four No. 4 steel bars continuous, with two bars near the bottom of the footing and two bars near the top. 7.2 Isolated square footings should contain, as a minimum, a grid of No. 4 steel bars on 12-inch centers, in both directions, with no less than two bars each way. 7.3 Floor slabs should be a minimum of 4 inches actual thickness and be reinforced with at least Nov»3**steel3>bars on- (18-inch centers, in both directions, placed at midheight in the slab. Slabs should be underlain by a 3-inch-thick layer of clean sand (S.E. = 30 or greater) overlying a 6-mil visqueen membrane. Slab subgrade soil shall be thoroughly moistened prior to placement of the vapor barrier and pouring of concrete. We recommend the project Civil/Structural Engineer incor- porate Isolation joints and sawcuts to at least one-fourth the thickness of the slab in any floor designs. The joints and cuts, if properly placed, should reduce the potential for and help control floor slab cracking. In no case, however, shall control joints be spaced farther than 25 feet apart. Due to a number of reasons (such as base preparation, construction techniques, curing procedures, and normal shrinkage of concrete), some cracking of slabs can still be expected. NOTE: The project Civil/Structural Engineer shall review all reinforcing schedules. The reinforcing minimums recommended herein are not to be construed as structural designs, but primarily as minimum safeguards to reduce possible crack separations. The actual reinforcing schedule shall be as per the direction of the Civil/Structural Engineer. OD ID I I I iI I I I I I I I I I I I I I I I Proposed Two Unit Condominium Project Job No. 90-5706 Carlsbad, California Page 8 8. As a minimum for protection of on-site improvements, it is recommended that all nonstructural concrete slabs (such as patios, walkways, driveways, etc.) be underlain by at least 2 inches of clean sand, include 6 x 6-10/10 welded wire mesh at midheight of the slab, and contain adequate isolation joints. The isolation joints and control joints shall be provided with a flexible joint filler which should be periodically inspected and be properly maintained. Improvements such as surrounding sidewalks should be provided with a drainage slope of at least 2 percent. The performance of on-site improvements can also be greatly affected by soil base preparation and the quality of construction, and is therefore the responsibility of the designer and the contractor installing the improvements. We recommend that the slab and footing subgrade soils be checked for proper moisture by our representative within 48 hours prior to concrete pouring. C. Retaining Walls 9. The active earth pressure (to be utilized in the design of canti- /-^fever walls) shall be based on an Equivalent Fluid Weight of(38^, pounds per cubic foot (for level backfill only). In the event that a retaining wall is surcharged by sloping backfill, the design active earth pressure shall be based on the appropriate Equivalent Fluid Weight presented in the following table: Height of Slope/Height of Wall* Slope Ratio 0.25 0.50 0/75 1.00(+) 2.0:1.0 44 48 50 52 *To determine design active earth pressures for ratios intermediate to those presented, interpolate between the stated values. flD ID I I I I I I I I I I I I I I I I I I I Proposed Two Unit Condominium Project Job No. 90-5706 Carlsbad, California Page 9 The design pressures presented above are based on utilization of an uncontrolled mixture of sandy soils native to the site in backfill operations. In the event that a retaining wall is to be designed for a restrained condition, a uniform pressure equal to 8xH (eight times the total height of retained wall, considered in pounds per square foot) shall be considered as acting everywhere on the back of the wall in addition to the design Equivalent Fluid Weight. Any other surcharge loads applied within a horizontal distance measured from the face of the wall equal to its height shall be considered in the structural design. 10. The passive earth pressure of the encountered natural-ground soils and any recompacted fill soils (to be used for design of shallow foundations and footings to resist the lateral forces) shall be based on an Equivalent Fluid Weight of 300 pounds per cubic foot. This passive earth pressure shall only be considered valid for design if the ground adjacent to the foundation structure is essentially level for a distance of at least three times the total depth of the foundation and is properly compacted or dense natural soil. 11. A Coefficient of Friction of 0.40 times the dead load may be used between the bearing soils and concrete foundations, walls, or floor slabs. D. Site Drainage Considerations 12. Adequate measures shall be taken to properly finish-grade the site after the structures and other improvements are in place. Drainage waters from this site and adjacent properties are to be CD 10 I I I I I I I I I I I I I I I I I I I Proposed Two Unit Condominium Project Job No. 90-5706 Carlsbad, California Page 110 directed away from foundations, floor slabs, footings, and slopes, onto the natural drainage direction for this area or into properly designed and approved drainage facilities. Roof gutters and downspouts should be installed on all structures, with runoff directed away fr.om the foundations via closed drainage lines. Proper subsurface and surface drainage will help minimize the potential for waters to seek the level of the bearing soils under the foundations, footings, and floor slabs. Failure to observe this recommendation could result in undermining and differential settlement of the structure of other improvements on the site. In addition, appropriate erosion-control measures shall be taken at all time during construction to prevent surface runoff waters from entering footing excavations and ponding on finished building pads or pavement areas. Proper subdrains and free-draining backwall material of filter fabric shall be installed behind all retaining walls on the subject project. Geotechnical Exploration, Inc. will assume no liability for damage to structures which is attributable to poor drainage. 13. Planter areas and planter boxes shall be sloped to drain away from the foundations, footings, and floor slabs. Planter boxes shall be constructed with a closed bottom and a subsurface drain, installed in gravel, with the direction of subsurface and surface flow away from the foundations, footings, and floor slabs, to an adequate drainage facility. E. General Recommendations 14. Following placement of any concrete floor slabs, sufficient drying time should be allowed prior to placement of floor coverings. Premature placement of floor coverings could result in degradation of adhesive materials and loosening of the finish-floor materials. ODUD I I I I I I I I I I I I I I I I I I I Proposed Two Unit Condominium Project Job No. 90-5706 Carlsbad, California Page 1 1 15. In order to minimize any work delays at the subject site during site development, this firm should be contacted 24 hours prior to any need for observation of footing excavations or field density testing of compacted fill soils. If possible, placement of formwork and steel reinforcement in footing excavations should not occur prior to observation of the excavations; in the event that our observations reveal the need for deepening or redesigning foundation structures at any locations, any formwork or steel reinforcement in the affected footing excavation areas would have to be removed prior to correction of the observed problem (i.e., deepening the footing excavation, recompacting soil in the bottom of the excavation, etc.). VIII. GRADING NOTES Any required grading operations shall be performed in accordance with the General Earthwork Specifications (Appendix B) and the require- ments of the City of Carlsbad Grading Ordinance. 16. Geotechnical Exploration, Inc. recommends that we be asked to verify the actual soil conditions revealed during site grading work and footing excavations to be as anticipated in this "Report of Soil Investigation." In addition, the compaction of any fill soils placed during site grading work must be tested. It is the responsibility of the grading contractor to comply with the requirements on the grading plans and the local grading ordinance. 17. It is the responsibility of the owner and/or developer to ensure that the recommendations summarized in the report are carried out in the field operations and that our recommendations for design of the project are incorporated in the building and grading plans. It is recommended that we review the grading and foundation plans prior to construction operations to verify that our recommendations are incorporated in the plans.

This firm does not practice or consult in the field of safety engineering. We do not direct the contractor's operations, and we cannot be responsible for the safety of personnel other than our own on the site; the safety of others is the responsibility of the contractor. The contractor should notify the owner if he considers any of the recommended actions presented herein to be unsafe. IX. LIMITATIONS Our conclusions and recommendations have been based upon all available data obtained from our field investigation and laboratory analysis, as well as our experience with the soils and formational materials located in the City of Carlsbad. Of necessity, we must assume a certain degree of continuity between exploratory excavations and/or natural exposures. It is, therefore, necessary that all observations, conclusions, and recommendations be verified at the time grading operations begin or when footing excavations are placed. In the event discrepancies are noted, additional recommendations may be issued, if required. The work performed and recommendations presented herein are the result of an investigation and analysis which meet the contemporary standard of care in our profession within the County of San Diego. No warranty is provided. This report should be considered valid for a period of three (3) years, and is subject to review by our firm following that time. If significant modifications are made to the building and/or grading plans, especially with respect to the height and location of the proposed structure, this report must be presented to us for immediate review and possible revision.

I I I I I I I I I I I I I I I I I I I APPENDIX B GENERAL EARTHWORK SPECIFICATIONS General The objective of these specifications is to properly establish procedures for the clearing and preparation of the existing natural ground or properly compacted fill to receive new fill; for the selection of the fill material; and for the fill compaction and testing methods to be used. Scope of Work The earthwork includes all the activities and resources provided by the contractor to construct in a good workmanlike manner all the grades of the filled areas shown in the plans. The major items of work covered in this section include all clearing and grubbing, removing and disposing of materials, preparing areas to he filled, compacting of fill, compacting of backfills, subdrain installations, and all other work necessary to complete the grading of the filled areas. Site Visit and Site Investigation 1. The contractor shall visit the site and carefully study it and make all inspections necessary in order to determine the full extent of the work required to complete all grading in conformance with the drawings and specifications. The contractor shall satisfy himself as to the nature, location and extent of the work; conditions, the conformation and condition of the existing ground surface; and the type of equipment, labor, and facilities needed prior to and during prosecution of the work. The contractor shall satisfy himself as to the character, quality and quantity of surface and subsurface materials or obstacles to be encountered. Any inaccuracies or discrepancies between the actual field conditions and the drawings, or between the drawings and specifications, must be brought to the engineer's attention in order to clarify the exact nature of the work to be performed. 2. A soils investigation report has been prepared for this project by GEI and it is available for review and should be used as a reference to the surface and subsurface soil and bedrock conditions on this project. Any recommendations made in the report of the soil investigation or subsequent reports shall become an addendum to these specifications. I I I I I I I I I I I I I I I I I I I Authority of the Soils Engineer and Engineering Geologist The soils engineer shall be the owner's representative to observe and test the construction of fills. Excavation and the placing of fill shall be under the observation of the soils engineer or his/her representative, and he/she shall give a written opinion regarding conformance with the specifications upon completion of grading. The soils engineer shall have the authority to cause the removal and replacement of porous topsoils, uncompacted or improperly compacted fills, disturbed bedrock materials and soft alluvium, and shall have the authority to approve or reject materials proposed for use in the compacted fill areas. The soil engineer shall have, in conjunction with the engineering geologist, the authority to approve the preparation of natural ground and toe-of-fill benches to receive fill material. The engineering geologist shall have the authority to determine the stability of the existing or proposed slopes and to determine the necessity of remedial measures. If any unstable condition is being created by cutting or filling, the engineering geologist and/or soil engineer shall advise the contractor and owner immediately and prohibit grading in the affected area until such time as corrective measures are taken. The owner shall decide all questions regarding: (1) the interpretation of the drawings and specifications, (2) the acceptable fulfillment of the contract on the part of the contractor, and (3) the matter of compensation. Clearing and Grubbing 1. Clearing and grubbing shall consist of the removal from all areas to be graded of all surface trash, abandoned improvements, paving, culverts, pipe, and vegetation (including — but not limited to — heavy weed growth, trees, stumps, logs and roots larger than 1-inch in diameter). 2. All organic and inorganic materials resulting from the clearing and grubbing operations shall be collected, piled and disposed of by the contractor to give the cleared areas a neat and finished appearance. Burning of combustible materials on-site shall not be permitted unless allowed by local regulations and at such times and in such a manner to prevent the fire from spreading to areas adjoining the property or cleared area. 3. It is understood that minor amounts of organic materials may remain in the fill soils due to the near impossibility of complete removal. The amount remaining, however, must be considered negligible and in no case can be allowed to occur in concentrations or total quantities sufficient to contribute to settlement upon decomposition. I I I I I I I I I I I I I I I I I I I Preparation of Areas to be Filled 1. After clearing and grubbing, all uncompacted or improperly compacted fills, soft or loose soils, or unsuitable materials, shall be removed to expose competent natural ground, undisturbed bedrock, or properly compacted fill as indicated in the soils investigation report or by our field representative. Where the unsuitable materials are exposed in final graded areas, they shall be removed and replaced as compacted fill. 2. The ground surface exposed after removal of unsuitable soils shall be scarified to a depth of at least 6 inches, brought to the specified moisture content, and then the scarified ground compacted to at least the specified density. Where undisturbed bedrock is exposed at the surface, scarification and recompaction shall not be required. 3. All areas to receive compacted fill, including all removal areas and toe-of-fill benches, shall be observed and approved by the soil engineer and/or engineering geologist prior to placing compacted fill. 4. Where fills are made on hillsides or exposed slope areas with gradients greater than 20 percent, horizontal benches shall be cut into firm, undisturbed natural ground in order to provide both lateral and vertical stability. This is to provide a horizontal base so that each layer is placed and compacted on a horizontal plane. The initial bench at the toe of the fill shall be at least 10 feet in width on firm, undisturbed, natural ground at the elevation of the toe stake placed at the bottom of the design slope. The engineer shall determine the width and frequency of all succeeding benches which will vary with the soil conditions and the steepness of the slope. Ground slopes flatter than 20 percent (5.0:1.0) shall be benched when considered necessary by the soils engineer. Fill and Backfill Material Unless otherwise specified, the on-site material obtained from the project excavations may be used as fill or backfill, provided that all organic material, rubbish, debris, and other objectionable material contained therein is first removed. In the event that expansive materials are encountered during foundation excavations within 3 feet of finished grade and they have not been properly processed, they shall be entirely removed or thoroughly mixed with good, granular material before incorporating them in fills. No footing shall be allowed to bear on soils which, in the opinion of the soils engineer, are detrimentally expansive — unless designed for this clayey condition. I I I I I I I I I I I I I I I I I I I However, rocks, boulders, broken portland cement concrete, and bituminous type pavement obtained from the project excavations may be permitted in the backfill or fill with the following limitations: 1. The maximum dimension of any piece used in the top 10 feet shall be no larger than 6 inches. 2. Clods or hard lumps of earth of 6 inches or in greatest dimension shall be broken up before compacting the material in fill. 3. If the fill material originating from the project excavation contains large rocks, boulders, or hard lumps that cannot be broken readily, pieces over 6 inches in diameter to 2 feet in maximum dimension may be used in fills below final subgrade if all pieces are placed in such a manner (such as windrows) as to eliminate nesting or voids between them. No rocks over 4 feet will be allowed in the fill. 4. Pieces larger than 6 inches shall not be placed within 12 inches of any structure. v 5. Pieces larger than 3 inches shall not be placed within 12 inches of the subgrade for paving. 6. Rockfills containing less than 40 percent of soil passing 3/4-inch sieve may be permitted in designated areas. Specific recommendations shall be made by the soils engineer and be subject to approval by the city engineer. 7. Continuous observation by the soils engineer is required during rock placement. 8. Special and/or additional recommendations may be provided in writing by the soils engineer to modify, clarify or amplify these specifications. 9. During grading operations, soil types other than those analyzed in the soil investigation report may be encountered by the contractor. The soils engineer shall be consulted to evaluate the suitability of these soils as fill materials. Placing and Compacting Fill Material 1. After preparing the areas to be filled, the approved fill material shall be placed in approximately horizontal layers, with lift thickness compatible to the material being placed and the type of equipment being used. Unless otherwise approved by the soils engineer, each layer spread for compaction shall not exceed 8 inches of loose thickness. Adequate drainage of the fill shall be provided at all times during the construction period. I I I I I I I I I I I I I I I I I I I 2. When the moisture content of the fill material is below that specified by the engineer, water shall be added to it until the moisture content is as specified. 3. When the moisture content of the fill material is above that specified by the engineer, resulting in inadequate compaction or unstable fill, the fill material shall be aerated by hlading and scarifying or other satisfactory methods until the moisture content is as specified. 4. After each layer has been placed, mixed and spread evenly, it shall be thoroughly compacted to not less than the density set forth in the specifications. Compaction shall be accomplished with sheepsfoot rollers, multiple-wheel pneumatic-tired rollers or other approved types of acceptable compaction equipment. Equipment shall be of such design that it will be able to compact the fill to the specified relative compaction. Compaction shall cover the entire fill area, and the equipment shall make sufficient trips to ensure that the desired density has been obtained throughout the entire fill. At locations where it would be impractical due to inaccessibility of rolling compacting equipment, fill layers shall be compacted to the specified requirements by hand-directed compaction equipment. 5. When soil types or combination of soil types are encountered which tend to develop densely-packed surfaces as a result of spreading or compacting operations, the surface of each layer of fill shall be sufficiently roughened after compaction to ensure bond to the succeeding layer. 6. Unless otherwise specified, fill slopes shall not he steeper than 2.0 horizontal to 1.0 vertical. In general, fill slopes shall be finished in conformance with the lines and grades shown on the plans. The surface of fill slopes shall be overfilled to a distance from finished slopes such that it will allow compaction equipment to operate freely within the zone of the finished slope, and then cut back to the finished grade to expose the compacted core. Alternate compaction procedures include the backrolling of slopes with sheepsfoot rollers in increments of 3 to 5 feet in elevation gain. Alternate methods may be used by the contractor but they shall be evaluated for approval by the soils engineer. 7. Unless otherwise specified, all allowed expansive fill material shall be compacted to a moisture content of approximately 2 to 4 percent above the optimum moisture content. Nonexpansive fill shall be compacted at near optimum moisture content. All fill shall be compacted, unless otherwise specified, to a relative compaction not less than 95 percent I I I I I I I I I I I I I I I I I I I for fill In the upper 12 inches of subgrades under areas to be paved with apshalt concrete or portland concrete, and not less than 90 percent for other fill. The relative compaction is the ratio of the dry unit weight of the compacted fill to the laboratory maximum dry unit weight of a sample of the same soil, obtained in accordance with A.S.T.M. D-1557 test method. 8. The observation and periodic testing by the soils engineer is intended to provide the contractor with an ongoing measure of the quality of the fill compaction operation. It is the responsibility of the grading contractor to utilize this information to establish the degrees of compactive effort required on the project. More importantly, it is the responsibility of the grading contractor to ensure that proper compactive effort is applied at all times during the grading operation, including during the absence of soils engineering representatives. Trench Backfill 1. Trench excavations which extend under graded lots, paved areas, areas under the influence of structural loading, in slopes or close to slope areas, shall be backfilled under the observations and testing of the soils engineer. All trenches not falling within the aforementioned locations shall be backfilled in accordance with the City or County regulating agency specifications. 2. Unless otherwise specified, the minimum degree of compaction shall be 90 percent of the laboratory maximum dry density. 3. Any soft, spongy, unstable, or other similar material encountered in the trench excavation upon which the bedding material or pipe is to be placed, shall be removed to a depth recommended by the soils engineer and replaced w ith bedding materials suitably densified. Bedding material shall first be placed so that the pipe is supported for the full length of the barrel with full bearing on the bottom segment. After the needed testing of the pipe is accomplished, the bedding shall be completed to at least 1 foot on top of the pipe. The bedding shall be properly densified before backfill is placed. Bedding shall consist of granular material with a sand equivalent not less than 30 or other material approved by the engineer. 4. No rocks greater than 6 inches in diameter will be allowed in the backfill placed between 1 foot above the pipe and 1 foot below finished subgrade. Rocks greater than 2.5 inches in any dimension will not be allowed In the backfill placed within 1 foot of pavement subgrade. I I I I I I I I I I I I I I I I I I I 5. Material for mechanically compacted backfill shall be placed in lifts of horizontal layers and properly moistened prior to compaction. In addition, the layers shall have a thickness compatible with the material being placed and the type of equipment being used. Each layer shall be evenly spread, moistened or dried, and then tamped or rolled until the specified relative compaction has been attained. 6. Backfill shall be mechanically compacted by means of tamping rollers, sheepsfoot rollers, pneumatic tire rollers, vibratory rollers, or other mechanical tampers. Impact-type pavement breakers (stompers) will not be permitted over clay, asbestos cement, plastic, cast iron, or nonreinforced concrete pipe. Permission to use specific compaction equipment shall not be construed as guaranteeing or implying that the use of such equipment will not result in damage to adjacent ground, existing improvements, or improvements installed under the contract. The contractor shall make his/her own determination in this regard. 7. Jetting shall not be permitted as a compaction method unless the soils engineer allows it in writing. 8. Clean granular material shall not be used as backfill or bedding in trenches located in slope areas or within a distance of 10 feet of the top of slopes unless provisions are made for a drainage system to mitigate the potential buildup of seepage forces into the slope mass. Observations and Testing 1. The soils engineers or their representatives shall sufficiently observe and test the grading operations so that he/she can state his/her opinion as to whether or not the fill was constructed in accordance with the specifications. 2. The soils engineers or their representatives shall take sufficient density tests during the placement of compacted fill. The contractor should assist the soils engineer and/or his/her representative by digging test pits for removal determinations and/or for testing compacted fill. In addition, the contractor should cooperate with the soils engineer by removing or shutting down equipment from the area being tested. 3. Fill shall be tested for compliance with the recommended relative compaction and moisture conditions. Field density testing should be performed by using approved methods by A.S.T.M., such as A.S.T.M. D1556, D2922, and/or D2937. Tests to determine density of compacted fill should be provided on the basis of not less than one test for each 2-foot vertical lift of the fill, but not less than one test I I I I I I I I I I I I I I I I I I I for each 1,000 cubic yards of fill placed. Actual test intervals may vary as field conditions dictate. In fill slopes, approximately half of the tests shall be made at the final fill slope, except that not more than one test needs to be made for each 50 horizontal feet of slope in each 2-foot vertical lift. Actual test intervals may vary as field conditions dictate. Fill found not to be conformance with the grading recommendations should be removed or otherwise handled as recommended by the soils engineer. Site Protection It shall be the grading contractor's obligation to take all measures deemed necessary during grading to maintain adequate safety measures and working conditions, and to provide erosion control devices for the protection of excavated areas, slope areas, finished work on the site and adjoining properties, from storm damage and floor hazard originating on the project. It shall be the contractor's responsibility to maintain slopes in their as-graded form until all slopes are in satisfactory compliance with the job specifications, all berms and benches have been properly constructed, and all associated drainage devices have been installed and meet the requirements of the specifications. All observations and testing services and approvals given by the soil engineer and/or geologist shall not relieve the contractor of his/her responsibilities of performing the work in accordance with these specifications. After grading is completed and the soils engineer has finished his/her observations and/or testing of the work, no further excavation or filling shall be done except under his/her observations. Adverse Weather Conditions 1. Precautions shall be taken by the contractor during the performance of site clearing, excavations and grading to protect the work site from flooding, ponding or inundation by poor or improper surface drainage. Temporary provisions shall be made during the rainy season to adequately direct surface drainage away from and off the work site. Where low areas cannot be avoided, pumps should be kept on hand to continually remove water during periods of rainfall. 2. During periods of rainfall, plastic sheeting shall be kept reasonably accessible to prevent unprotected slopes from becoming saturated. Where necessary during periods of rainfall, the contractor shall install checkdams, desilting basins, rip-rap, sand bags, or other devices or methods necessary to control erosion and provide safe conditions. I I I I I I I I I I I I I I I I I I I 3. During periods of rainfall, the soils engineer should be kept informed by the contractor as to the nature of remedial or preventative work being performed (e.g. pumping, placement of sand bags or plasti sheeting, other labor, dozing, etc.). 4. Following periods of rainfall, the contractor shall contact the soils engineer and arrange a walk-over of the site in order to visually assess rain-related damage. The soils engineer may also recommend excavations and testing in order to aid in his assessments. At the request of the soils engineer, the contractor shall make excavations in order to evaluate the extent of rain-related damage. 5. Rain-related damage shall be considered to include, but may not be limited to, erosion, silting, saturation, swelling, structural distress, and other adverse conditions identified by the soils engineer. Soil adversely affected shall be classified as Unsuitable Materials and shall be subject to overexcavation and replacement with compacted fill or other remedial grading as recommended by the soils engineer. 6. Relatively level areas, where saturated soils and/or erosion gullies exist to depths of greater than 1.0 foot, shall be overexcavated to unaffected, competent material. Where less than 1.0 foot in depth, unsuitable materials may be processed in place to achieve near-optimum moisture conditions, then thoroughly recompacted In accordance with the applicable specifications. If the desired results are not achieved, the affected materials shall be overexcavated, then replaced in accordance with the applicable specifications. 7. In slope areas, where saturated soil and/or erosion gullies exist to depths of greater than 1.0 foot, they shall be overexcavated and replaced as compacted fill in accordance with the applicable specifi- cations. Where affected materials exist to depths of 1.0 foot or less below proposed finished grade, remedial grading by moisture condi- tioning in place, followed by thorough recmpaction in accordance with the applicable grading guidelines in accordance with the applicable grading guidelines herein may be attempted. If materials shall be overexcavated and replaced as compacted fill in accordance with the slope repair recommendations herein. As field conditions dictate, other slope repair procedures may be recommended by the soils engineer.
