All new shearwalls along Line A shown on sheet 5-2 at the first story need to be upgraded to Typ&2° shearwalls, per the shearwH schedule. The huldowns already shown, HD2A / PHD2, may remain the same, Maintain the Type '1' shearwalls shown along Line A; add a new Type '1' shearwail at the insidof the garage along Line A. This new Type 1 sheatwall is to be 4.0 ft long, and no holdowas are required. It should be located as dose to Line 3 as possible. (Calculations enclosed) lB Since the building paper & stucco mesh are already attached to the building, Mike & I looked at our calculations again. Our Initial calculations were conservative in that we used an R fdctor of 4.5. When only wood-sheathed shearwalls are utilized (which this building has), we are allowed to use an R factor of 5.5. By recalculating these shearwalls with this reduced loading, the twoiemalnfnçtType 2' shearwalls are sçtent. (This reduced shearwall calculation Is enclosed). - Therefore, n9l having the 3 & shearwalt at the entry area shown on sheet S-3 at Line 4 Is structurally acceptable Please review, and call our office should you have any questions.

At the upper roof level of LIne 2, the shearwall at that area has been designed to be a Type '1" sheatwall that Is 6-6" long. The gable truss above the double top plate is only required to have Type 11' shearwall sheathing and nailing directly above the designated shearwall. The top chord of the gable truss shall have continuous roof sheathing boundary nailing (per structural details), so the top chord is sufficient to act as a collector member, Please call our office should you have any questions. rTlI Vince Nutile, P.E. - - -.'--' - -- -__ - -LU No. 4352 21/0 5a'i rVw Awm, e 2X 5M 1'Iez CA 921I0 7 V1,-r. 61455 1170 TO 176725253 INSPEMON SRULCES cpX NO. 7W, 737 0898 Oct. ze i * ' !III - -.

Dear Mr. & Mrs. Sabala: In accordance with your request, a representative of Professional Service Industries, Inc. (PSI) has observed the excavations for the proposed foundations at the subject site. Our services have been performed pursuant to the General Conditions contained in PSI Proposal No. 062-130 dated August 2, 1999. Based on our observations, the foundation excavations appear to extend to the minimum embedments and widths and into adequate bearing strata as recommended in our referenced report. Our observations also indicate that the bearing soils appear to possess a very low expansion potential and are generally consistent with those geotechnical conditions discussed in our referenced report. Prior to placement of concrete, the footing excavations should be cleared of any loose soil and debris. We appreciate this opportunity to be of service to you. If you have any questions or need further information, please do not hesitate to contact us. - Respectfully submitted, Professional Service Industries, Inc. William R.

The purpose of this addendum is to address the subject site's susceptibility to liquefaction, given a design earthquake along a nearby late Quaternary fault. Our referenced subsurface exploration reveals that the project site is underlain by materials comprising the Pleistocene-aged Bay Point Formation. 00f etperienee with these materials in the general vicinity of the site indicates that the Bay Point Formation is weakly to moderately indurated and is not typically susceptible to liquefaction. In addition, no groundwater was encountered in any of our exploratory excavations during our referenced exploration. Based on the geotechnical conditions encountered during our referenced exploration including: area seismicity; the nature of the geologic materials underlying the site; and the anticipated lack of a static, near. surface groundwatcr table, it is our opinion that the site possesses a low risk potential for liquefaction, given a design earthquake along a nearby late Quaternary fault.

Three exploratory test pits have been excavated and selected soil samples were tested in the laboratory as part of our limited exploration. In general, the subject residence appears to be underlain by soils comprising weathered Baypoint Formation/Topsoil materials, which are mantled by approximately 12 inches of existing fill soils. The weathered formational/topsoil materials were observed in our test pits to consist of dark reddish-brown to medium orangish-brown silty sands with occasional rootlets (SM). These materials were generally observed to be moist to very moist and medium dense at the time of our limited exploration. The encountered fill materials were observed to typically consist of dark brown silty sands with occasional rootlets (SM), which were damp to very moist and loose to medium dense at the time of our limited exploration. Results of our laboratory testing indicate that the encountered upper soils possess a very low expansion potential. Refusal/hard rock materials were not encountered within either of our three exploratory test pits. As noted during our limited subsurface exploration, the encountered portions of the existing building foundation system were observed to have embedments of between 12 and 15 inches below existing site grades, which is within the current industry standards. Since it is not known whether the foundations are adequately reinforced, it is recommended that the suitability of the existing foundations to receive the additional second-story loading be further evaluated by a structural engineer. Based on the results of our limited subsurface exploration, the subsurface conditions at the site generally appear to be suitable for the use of shallow foundations for the support of the proposed structure loads, provided the recommendations contained herein are properly incorporated into the proposed construction. Details related to site development, foundation design, seismicity, and construction considerations are included in subsequent sections of this report. The owner/designer should not rely solely on this Executive Summary and must read and evaluate the entire contents of this report prior to utilizing our engineering recommendations in preparation of design/construction documents. 1370 Pine Avenue, Carlsbad, CA - Pro:ssional Service Industries, Inc. Li 2 PROJECT INFORMATION Project Authorization Professional Service Industries, Inc. (PSI) has completed a limited geotechnical exploration for the proposed second-story addition to the existing residence at 1370 Pine Avenue in Carlsbad, California. Our services were authorized by Mrs. Anne Sabala on August 8, 1999 by signing our pioposal. This exploration was accomplished in general accordance with PSI Proposal No. 062-130 dated August 2, 1999. Project Description Preliminary project information was provided to us by Mr. & Mrs. Sabala on August 2, 1999. Based on our review of the provided information, we understand the proposed construction at the site will include a second-story addition onto the northern portion of the existing structure, an expansion of the existing kitchen, and other associated improvements. In addition, we understand that no site grading is currently planned (beycnd the clearing and grubbing of existing vegetation and surficial debris as necessary). The geotechnical recommendations presented in this report are based on the. provided project information, proposed building locations, and the subsurface materials described in this report. If any of the noted information is incorrect, please inform PSI in writing so that we may amend the recommendations presented in this report if appropriate and if desired by the client. PSI will not be responsible for the implementation of its recommendations when it is not notified of changes in the project. Purpose and Scope of Services The purpose of this limited geotechnical exploration report was to explore the subsurface conditions at the site to enable an evaluation of acceptable foundation systems for the proposed construction. This report briefly outlines the testing procedures, describes the site and subsurface conditions, and presents geotechnical recommendations for foundation design and for general site development. Our scope. of services included the excavation, logging and sampling of three exploratory test pits at the site to depths on the order of 11/2 to 21/2 feet below the existing ground surface, appropriate laboratory testing, and preparation of this geotechnical report. This report briefly outlines the testing procedures, presents available project information, describes the site and subsurface conditions, and presents recommendations regarding the following: 1370 Pine Avenue, Carlsbad, CA Professional Service Industries, Inc. 3 - Grading procedures for site development. - Suitable foundation types, depths, allowable bearing capacities, and an estimate of potential settlement. - Lateral earth pressures for retaining wall design (if proposed). - Comments regarding factors that will impact construction and performance of the proposed construction. Our scope of services did not include an environmental assessment for determining the presence or absence of wetlands, or hazardous or toxic materials in the soil, bedrock, surface water, groundwater, or air on or below, or around this site. Any statements in this report or on the exploration logs regarding odors, colors, and unusual or suspicious items or conditions are strictly for informational purposes. SITE AND SUBSURFACE CONDITIONS Site Location and Description The subject site is located at 1370 Pine Avenue in Carlsbad, California. Current access to the site is off of Pine Avenue which bounds the property to the southeast. The site is also bounded to the northeast, northwest and southwest by existing residential developments. Existing development at the site includes a single-story detached residence of wood-frame and slab-on-grade construction and associated appurtenances. Our observation of the exterior of the residence indicates that the existing foundation system appears to be performing reasonably well. The ground surface elevation at the relatively level site is approximately 120 feet above Mean Sea Level (MSL). The approximate ground surface elevation was estimated from the San Luis Rey, California 7.5 minute Topographic Survey prepared by the U.S. Geologic Survey. Regional Geology The subject site lies within the coastal portion of the Penninsular Ranges Geomorphic Province of California. According to pertinent regional geologic literature, the project site is underlain by Quaternary-aged Terrace Deposits associated with the Baypoint Formation (Kennedy and Tan, 1996). 1370 Pine Avenue, Carlsbad, CA Professional Service Industries, Inc. 4 Foundation and Subsurface Conditions The site subsurface conditions were explored with three exploratory test pits, each directly adjacent to the existing residential structure (see Figure 2 - Test Pit Location Map). The test pits were advanced utilizing manual excavation equipment and representative disturbed and relatively undisturbed soil samples were routinely obtained during the excavation process. Exploration and sampling techniques were accomplished generally in accordance with ASTM procedures. As encountered in our exploratory test pits, the subject residence appears to be underlain by soils comprising weathered Baypoint Formation/Topsoil materials, which are mantled by approximately 12 inches of existing fill soils. The weathered formational/topsoil materials were observed in our test pits to consist of dark reddish-brown to medium orangish-brown silty sands with occasional rootlets (SM). These materials were generally observed to be moist to very moist and medium dense at the time of our limited exploration. The encountered fill soils were - observed to typically consist of dark brown silty sands with occasional rootlets (SM), which were damp to very moist and loose to medium dense at the time of our limited exploration. Results of our laboratory testing indicate a very low expansion potential (UBC 18-2) for the encountered upper soils. Refusal/hard rock materials were not encountered within either of our three exploratory test pits. The existing continuous foundations supporting the residence were observed in our test pits to have embedments of between 12 and 15 inches below existing grade, which is within the current Uniform Building Code Guidelines for footings supporting single-story structure. Our scope of services did not include the evaluation of existing reinforcement (if any) within the footings. As such, PSI cannot comment at this time about whether the existing foundations have been adequately reinforced in accordance with industry standards. J The above subsurface description is of a generalized nature to highlight the major subsurface stratification features and material characteristics. The exploration logs included in the appendix should be reviewed for specific information at the individual test pit locations. These records include soil descriptions, stratifications, penetration resistances, locations of the samples and laboratory test data. The stratifications shown on the exploration logs represent the } conditions only at the actual test pit locations at the time of our exploration Variations may Li occur and should be expected at some distance from the test pits. The stratifications which represent the approximate boundary between subsurface materials and the actual transition may be gradual. The samples which were not altered by laboratory testing will be retained for 60 days from the date of this report and then will be discarded. 1370 Pine Avenue, Carlsbad, CA Professional Service Industries, Inc. Select soil samples were tested in the laboratory to determine materials properties for our geotechnical evaluation. Laboratory testing was accomplished generally in accordance with ASTM procedures. A brief discussion of the laboratory tests performed and the results of our testing are presented in Appendix C. Groundwater Information Groundwater was not encountered within the maximum explored depth of 21/2 feet below the existing ground surface in our exploratory test pits, at the time of our exploration. However, it is possible that transient oversaturated ground conditions at shallower depths could develop at a later time due to periods of heavy precipitation, landscape watering, leaking water lines, or other unforeseen causes. SEISMICITY Regional Seismicity Generally, seismicity within California can be attributed to faulting due to regional tectonic movement. This includes the San Andreas Fault, the Rose Canyon Fault, the offshore segment of the Newport-Inglewood Fault, and most parallel and subparallel faulting within the State. The portion of California which includes the subject site is considered seismically highly active (UBC Seismic Zone 4). Seismic hazards within the site can be attributed to potential groundshaking resulting from earthquake events along nearby or more distant faulting. According to the regional geologic literature, the closest known Late-Quaternary fault is the Rose Canyon Fault located approximately 5.4 miles southwest of the site. Several potentially active and pre-Quaternary faults also occur within the regional vicinity. Currently, the seismological literature presents varying opinions regarding seismicity for nearby potentially active and pre-Quaternary faults. As such, the following Seismic Analysis only considers the effects of active faulting. Seismic Analysis The seismicity of the site was evaluated utilizing deterministic methods for active Quaternary faults within the regional vicinity. According to the Aiquist-Priolo Special Studies Zones Act of 1972 (revised 1994) Quaternary faults have been classified as active faults which show apparent surface rupture during the last 11,000 years (ie., Holocene time). This site is not currently within a mapped Earthquake Fault Zone (Hart and Bryant, 1997). ii 1370 Pine Avenue Carlsbad CA Professional Service Industries Inc 6 Deterministic Analysis - Deterministic seismicity at the site was evaluated with the Eqfault computer program (Blake, 1995), which utilizes a digitized map of known late Quaternary earthquake faults, a catalog of the estimated credible and potential earthquakes for each fault, and a user specified attenuation relationship (Campbell, et. al., 1994). Output from the Eqfault program is presented in Appendix D. Based on our analysis, 18 Late-Quaternary faults were located within a 62 mile radius of the site. The site is subject to a Maximum Credible Earthquake of 6.9 Magnitude along the Rose Canyon Fault located approximately 5.4 miles southwest of the site, with a corresponding Peak Ground Acceleration on the order of 0.39g. The Maximum Credible Earthquake is defined as the maximum earthquake that appears capable of occurring under the presently known tectonic framework. Additionally, the site is subject to a Maximum Probable Earthquake of 5.8 Magnitude, along the offshore segment of the Newport-Inglewood Fault, with its southern terminus located approximately 5 miles northwest of the site, with a corresponding Peak Ground Acceleration of approximately 0.22g. The Maximum Probable Earthquake is defined as the maximum earthquake that is considered likely to occur during a 100-year time interval. Earthquake Design Parameters In accordance with the evaluation summarized in the Seismic Analysis section of this J report, the Peak Ground Acceleration at the site ranges from 0.22g (Probable Earthquake sources) to 0.39g (Credible Earthquake sources). For structural design purposes, a damping ratio not greater than 5 percent of critical damping, and a soil profile type 5D (UBC Table 16-J) J are recommended. Based upon a distance of approximately 8.5 km from the site to the Rose Canyon Fault Zone and the offshore segment of the Newport-Inglewood Fault Zone (Type B 1 seismic sources per the 1997 edition of the Uniform Building Code), near source factors N a= 1.0 and N,=1.06 are recommended for the seismic design of the proposed addition. Other earthquake-resistant design parameters are recommended to be obtained from the Uniform j Building Code (UBC) 1997 Edition, Volume 2, Chapter 16, Divisions IV and V, utilizing a Seismic Zone 4 and a Soil Profile Type SD. If site-dependent earthquake response spectra or other specific design parameters are deemed necessary by the project structural engineer, or are required by the local governmental agency who has jurisdiction over the project, the geotechnical engineer should be promptly informed for further evaluation. In addition, design of structures should comply with the requirements of the governing jurisdiction's building codes and standard practices of the Structural Engineers Association of California. 1370 Pine Avenue, Carlsbad, CA Professional Service Industries, Inc. J 7 EVALUATION AND RECOMMENDATIONS The proposed construction at the site should be performed in accordance with the following recommendations and the standard guidelines for grading projects included in Appendix E. In case of conflict, the following recommendations shall supersede those in the appendix. Site Preparation Initially, all trees, loose topsoil, undocumented fill and deleterious material, as well as any existing structures, foundations, slabs, pavements, retaining walls, and utilities, must be removed from the areas proposed for construction and the resulting excavations backfilled with engineered fill as described below. The contractor should refer to local codes or ordinances for proper removal and disposal of any existing underground tanks, fuel lines and soil or other tank backfill material which may have been exposed to possible fuel leakage. Stripping operations should extend a minimum of 5 feet beyond the proposed pavement and building limits. After removal of any unsuitable materials as discussed above, the base of the resulting excavations should be scarified to a minimum depth of 6 to 8 inches, moisture conditioned as necessary to achieve a near optimum moisture content, and recompacted to a minimum 90 percent relative compaction (based on ASTM test method D-1557). The removed/replacement soils should be moisture conditioned to a near optimum moisture content and recompacted to a minimum 90 percent relative compaction (based on ASTM test method D-1557) until finished grades are reached. This earthwork should extend a minimum of 5 feet beyond the proposed building footprints. Fill materials should be free of organic or other deleterious materials, have a maximum particle size of 3 inches or less, have a liquid limit of less than 45 and a olasticity index of less than 25. The on-site soils are generally considered suitable for use as structural fill, provided they are properly processed. Fill should be placed in maximum loose lifts of 8 inches and should be compacted within the range of 3 percentage points below to 3 percentage points above the optimum moisture content value. If water must be added, it should be uniformly applied and thoroughly mixed into the soil by discing or scarifying. Each lift of compacted engineered fill should be tested by a representative of the geotechnical engineer prior to placement of subsequent lifts. The edges of compacted fill should extend at least 5 feet beyond the edges of buildings prior to sloping. Structural fill should be compacted to at least 90 percent of the maximum dry density (based on ASTM D1557). 1370 Pine Avenue, Carlsbad, CA - P:ofessional Service Industries, Inc. - 8 Non-structural fill adjacent to structural fill should be placed in unison to provide lateral support. Backfill along building walls must be placed and compacted with care to ensure excessive unbalanced lateral pressures do not develop. The type of fill material placed adjacent to below grade walls must be properly tested by the geotechnical engineer with consideration for the lateral earth pressure used in the wall design. Foundation Recommendations As discussed previously, the observed portions of the existing foundation system supporting the single-story residence had embedments of between 12 and 15 inches below adjacent grade, which we note is within the current Uniform Building Code guidelines for footings supporting single-story structures. It is not known if the existing footings are properly reinforced, as evaluation of the foundation reinforcement was not within our authorized scope of services. As a result, further evaluation of the suitability of the existing foundations to receive second-story loading should be performed as necessary by a qualified structural engineer. At that time, supplemental recommendations to improve the footings' suitability can be made (if warranted). Additional structure load imposed by the second story addition may be supported on conventional continuous or isola,ted spread footings which are entirely supported by firm natural soils or properly compacted fill soils. Footings for the one- or two-story residential structure should be embedded at least 6 inches below the lowest adjacent finish grade. At this depth, footings may be designed for an allowable soil bearing value-of 2000 psf. This bearing value may be increased by one-third for loads of short duration, such as wind or seismic forces. Continuous footings should have a minimum width of twelve inches, while isolated spread footings should have a minimum width of 24 inches. Appropriate footing reinforcement should be provided in accordance with the Structural Engineer's design Attention should be given in designing the foundation for the addition adjacent to the existing building. It is advisable to place the foundations for the addition at the same level as the foundations for the existing building so that the new footings will not undercut the soil beneath the existing footings. In spite of these precautions, small differential movements between the adjacent structures may be experienced. Construction joints should be provided between the existing building and the addition. The foundation excavations should be observed by a representative of PSI prior to steel or concrete placement to assess that the foundation materials are capable of supporting the design loads and are consistent with the materials discussed in this report. Soft or loose soil zones encountered at the bottom of the footing excavations should be removed as directed by the geotechnical engineer. Cavities formed as a result of excavation of soft or loose soil zones should be backfihled with lean concrete or dense graded compacted crushed stone. 1370 Pine Avenue, Carlsbad, CA Professional Service Industries, Inc. 4 After opening, footing excavations should be observed and concrete placed as quickly as possible to avoid exposure of the footing bottoms to wetting and drying. Surface run-off water should be drained away from the excavations and not be allowed to pond. If possible, the foundation concrete should be placed during the same day the excavation is made. If it is required that footing excavations be left open for more than one day, they should be protected to reduce evaporation or entry of moisture. Based on the known subsurface conditions and site geology, laboratory testing and past experience, we anticipate thariroperly designed and constructed footings supported on the recommended materials should experience maximum total and differential settlements between adjacent columns of less than one inch and ½ inches, respectively. While settlement of this magnitude is generally considered tolerable for structures of the type proposed, the design of masonry walls should include provisions for liberally spaced, vertical control joints to minimize the affects of cosmetic "cracking". Be advised that as a part of the foundation design election process, there is always a cost benefit evaluation. Although we are recommending a specific foundation type, we have not accomplished the cost/benefit evaluation. Structural Setback We recommend a minimum horizontal setback distance from the face of descending slopes and retaining walls for all structural footings and settlement-sensitive structures. This distance is measured from the outside bottom edge of the footing, horizontally to the slope face or the wall face and should be a minimum of H/2, where H is the wall height or slope height (in feet). The setback should not be less than 5 feet and need not be greater than 10 feet. Please note that the soils within the structural setback area possess poor lateral stability, and improvements (such as retaining walls, sidewalks, fences, pavements, etc.) constructed within this setback area may be subject to lateral movement and/or differential settlement. Floor Slab Recommendations New floor slabs-on-grade within the existing structure may be designed by the structural engineer using a coefficient of subgrade reaction of 100 pci and assuming a very low expansion potential (UBC 18-2). Based on geotechnical considerations, it is recommended that the interior slabs be at least 4 inches in nominal thickness, and minimally reinforced with 6x6 - 10/10 welded wire mesh, or in accordance with the structural engineer's requirements. Care should be taken by the contractor to ensure that the reinforcement is placed and maintained at slab midheight. Floor slabs should be suitably reinforced and jointed so that a small amount of independent movement can occur without causing damage. 1370 Pine Avenue, Carlsbad, CA - Professional Service Industries, Inc. 10 Slabs should be underlain by a capillary break at least 4 inches thick, consisting of coarse sand, gravel, or crushed rock. In moisture sensitive flooring areas, such as carpeted or linoleum covered areas, the slab should be additionally underlain (between the slab and capillary break) by at least two (2) inches of clean sand and a minimum 6-mil visqueen barrier. If the additional sand layer and visqueen are placed beneath the slab, the thickness of the capillary break layer may be reduced to 2 inches. The visqueen sheet should be sealed along the edges to prevent lateral migration of soil moisture from adjacent non-visqueen areas. Prior to placement of clean sand and slab-on-grade, the visqueen sheet should be thoroughly inspected for cracks, punctures, tears, and holes. If necessary, the visqueen should be replaced or patched to assure a fully functional entity. Some minor cracking of slabs can be expected due to shrinkage. The potential for this slab cracking can be reduced by careful control of water/cement ratios in the concrete. The contractor should take appropriate curing precautions during the pouring of concrete in hot weather to minimize the cracking of slabs. We recommend that a slipsheet (or equivalent) be utilized if grouted fill, tile, or other floor sensitive floor covering is planned directly on concrete slabs. All slabs should be designed in accordance with structural considerations. Lateral Earth Pressures and Resistance The following preliminary lateral earth pressure values for level or sloping backfill are recommended for retaining walls backfilled (if proposed) with approved granular soils. Equivalent Fluid Weight (pcfl Conditions Level Backfill 2:1 Sloping Backfill Active 35 55 At-Rest 55 70 Passive (Compacted Fill) 300 150 (sloping downward) Unrestrained (yielding) cantilever walls should be designed for an active equivalent pressure value provided above. In the design of walls restrained from movement at the top (non- yielding) such as basement walls, the at-rest pressures should be used. The above values assume backfill soils will have a very low expansion potential and free-draining conditions. If conditions other than those covered herein are anticipated, the equivalent fluid pressures should be provided on an individual basis by the geotechnical engineer. Wall footings should be designed in accordance with the Foundation Recommendations section of this report and reinforced in accordance with structural considerations. For all retaining walls, we recommend a minimum horizontal distance from the outside base of the footing to daylight of eight feet. 1370 Pine Avenue, Carlsbad, CA Professional Service Industries, Inc. - 11 It is recommended that all below-grade walls and retaining walls be provided with a positive foundation drainage system. A typical below-grade wall drain would consist of a minimum 4-inch flexible or, rigid perforated pipe surrounded by 3/4 inch crushed rock and wrapped in a non-woven geotextile fabric (consisting of Mirafi 140N or approved equivalent). The subsurface drainage system should be tied to the storm drainage system, allowed to daylight downslope, or collected in a sump and pumped out. This system typically is installed directly on top of the retaining wall footing. Retaining wall backfill should consist of approved granular material. This fill material should be compacted to at least 90 percent of the maximum dry density (as determined by ASTM D1557). Flooding or jetting of the backfill should not be permitted. Granular backfill should be capped with relatively impervious fill to seal the backfill and reduce the potential for saturation. Cantilever or restrained walls subject to uniform surcharge loads should be designed for an additional uniform lateral pressure equal to one-third the anticipated surcharge pressure in the case of the cantilevered walls (active conditions), and one-half the anticipated surcharge in the case of restrained walls (at-rest conditions). It should be noted that the use of heavy compaction equipment in close proximity to retaining structures can result in wall pressures exceeding design values and corresponding wall movement greater than normally associated with the development of active conditions. In this regard, the contractor should take appropriate precautions during the backfill placement. Lateral soil resistance developed against lateral structural movement can be obtained from the passive pressure value provided above. Further, for sliding resistance, a friction coefficient of 0.35 may be used at the concrete and soil interface. These values may be increased by one- third when considering loads of short duration including wind or seismic loads. The total resistance may be taken as the sum of the frictional and passive resistance provided that the passive portion does not exceed two-thirds of the total resistance. Pavement Recommendations The providing of pavement design recommendations was not within our authorized scope of services. Such recommendations, based upon additional laboratory testing of subgrade materials, can be provided by this office upon request. 1370 Pine Avenue, Carlsbad, CA Prcfessional Service Industries, Inc. I 12 CONSTRUCTION CONSIDERATIONS It is recommended that PSI be retained to provide observation and t--sting of construction activities involved in the foundation, earthwork, and related activities of this project. PSI cannot accept any responsibility for any conditions which deviated from those described in this report, nor for the performance of the foundation if not engaged to also provide construction observation and testing for this project. Moisture Sensitive Soils/Weather Related Concerns The upper soils encountered at this site may be sensitive to disturbances caused by construction traffic and to changes in moisture content. During wet weather periods, increases in the moisture content of the soil can cause significant reduction in the soil strength and support capabilities. In addition, soils which become wet may be slow to dry and thus significantly retard the progress of grading and compaction activities. It will, therefore, be advantageous to perform earthwork and foundation construction activities during dry weather. The nature of the encountered soils makes them particularly susceptible to erosion during periods of inclement weather. As a result, the Project Engineer/Architect and Grading Contractor should take appropriate precautions to reduce the potential for erosion during and after construction. Drainage and Groundwater Considerations Our experience indicates that surface or near-surface ground water conditions can develop in areas where ground water conditions did not exist prior to site development, especially in areas where a substantial increase in surface water infiltration results from landscape irrigation. This sometimes occurs where relatively impermeable and/or cemented formational materials are overlain by fill soils. In addition, during retaining wall excavations, seepage may be encountered. We recommend that a representative of PSI be present during grading operations to evaluate areas of seepage. Drainage devices for reduction of water accumulation can be recommended if these conditions occur. 1370 Pine Avenue, Carlsbad, CA Professional Service Industries, Inc. 13 Water should not be allowed to collect in the foundation excavation, on floor slab areas, or on prepared subgrades of the construction area either during or after construction. Undercut or excavated areas should be sloped toward one corner to facilitate removal of any collected rainwater, groundwater, or surface runoff. Positive site drainage should be provided to reduce infiltration of surface water around the perimeter of the building and beneath the floor slabs. The grades should be sloped away from the building and surface drainage should be collected and discharged such that water is not permitted to infiltrate the backfill and floor slab areas of the building. Excavations In Federal Register, Volume 54, No. 209 (October 1989), the United States Department of Labor, Occupational Safety and Health Administration (OSHA) amended its "Construction Standards for Excavations, 29 CFR, part 1926, Subpart P". This document was issued to better insure the safety of workmen entering trenches or excavations. It is mandated by this federal regulation that excavations, whether they be utility trenches, basement excavation or footing excavations, be constructed in accordance with the new OSHA guidelines. It is our understanding that these regulations are being strictly enforced and if they are not closely followed, the owner and the contractor could be liable for substantial penalties. The contractor is solely responsible for designing and constructing stable, temporary excavations and should shore, slope, or bench the sides of the excavations as required to maintain stability of both the excavation sides and bottom. The contractor's "responsible person", as defined in 29 CFR Part 1926, should evaluate the soil exposed in the excavations as part of the contractor's safety procedures. In no case should slope height, slope inclination, or excavation depth, including utility trench excavation depth, exceed those specified in local, state, and federal safety regulations. We are providing this information solely as a service to our client. PSI does not assume responsibility for construction site safety or the contractor's or other parties compliance with local, state, and federal safety or other regulations. Trench Backfill r Except where extending perpendicular under proposed foundations, utility trenches I should be constructed outside a 1:1 projection from the base-of-footings. Trench excavations for utility lines which extend under structural areas should be properly backfilled and compacted. 1370 Pine Avenue, Carlsbad, CA Professional Service Industries, Inc. 14 Utilities should be bedded and backfilled with clean sand or approved granular soil to a j depth of at least 1-foot over the pipe. This backfill shall be uniformly watered and compacted to a firm condition for pipe support. The remainder of the backfill shall be typical on-site soil, or imported soil, which shall be placed in lifts not exceeding 8 inches in thickness, watered or aerated to optimum moisture content, and mechanically compacted to at least 90 percent of maximum dry density (based on ASTM D1557). REPORT LIMITATIONS The recommendations submitted are based on the available subsurface information obtained by PSI and design details furnished by Mr. Guy Sabala and Mrs. Anne Sabala for the proposed project. If there are any revisions to the plans for this project or if deviations from the subsurface conditions noted in this report are encountered during construction, PSI should be notified immediately to determine if changes in the foundation recommendations are required. If PSI is not retained to perform these functions, PSI will not be responsible for the impact of those conditions on the project. The geotechnical engineer warrants that the findings, recommendations, specifications, or fl professional advice contained herein have been made in accordance with generally accepted J professional geotechnical engineering practices in the local area. No other warranties are implied or expressed. After the plans and specifications are more complete, the geotechnical engineer should be retained and provided the opportunity to review the final design plans and specifications to check that our engineering recommendations have been properly incorporated into the design documents. At this time, it may be necessary to submit supplementary recommendations. This report has been prepared for the exclusive use of Mr. Guy Sabala and Mrs. Anne Sabala for the specific application to the proposed second-story addition to the residence at 1370 Pine Avenue in Carlsbad, California. 1370 Pine Avenue, Carlsbad, CA - Professional Service Industries, Inc. 1370 Pine Avenue ,Carlsbad, CA - Professional Service Industries, Inc. \'(, \':4. •-\Hf '. %"_) PaIul;\ " IN- ;~J\~ & \31- -isposa, n5 U -, ping 17 Shop -S Center 1- 7 r'3&T Buena Vvis V. , 3 T11S AV NN Q, 12 S AV r led KNOE\Rv\\c9 SITE LOCATION LAG UNA \ 4 ra ry ( £2. mt High Kell and Aca oo 20, PROJECT NAME Proposed Secotid-Story Addition Figure 1 - Site Location Map To Sabala Residence 1370 Pine Avenue PROJECT NO.

LABORATORY TEST RESULTS Laboratory Testing Program Laboratory tests were performed on representative soil samples to determine their relative engineering properties. Tests were performed in accordance with test methods of the American Society for Testing Materials or other accepted standards. The following presents a brief description of the various test methods used. Classification - Soils were classified visually according to the Unified Soil Classification System. Visual classifications were supplemented by laboratory testing of selected samples in accordance with ASTM D2487. The soil classifications are shown on the Exploration Logs, Appendix B. Moisture-Density Relationship - Laboratory compaction tests were performed in accordance with ASTM D1557, Method A. A mechanically-operated ram was used during the compaction process. Direct Shear Tests - Consolidated, drained, direct shear tests were performed on undisturbed samples in accordance with ASTM D-3080. The undisturbed samples were tested in a saturated condition using normal loads of 1 ksf, 2 ksf, and 4 ksf. Expansion Index - Expansion testing was performed on representative samples of the fl upper on-site soils, remolded and surcharged to 144 pounds per square foot in accordance with ii the Uniform Building Code Standard No. 18-2. Soil Sulfate Test - In order to estimate the concrete degradation potential of soils, the content of soluble sulfates was determined in accordance with Cal Test Method 417A.

OBLIGATIONS OF PARTIES The Geotechnical Consultant should provide observation and testing services and should make evaluations in order to advise the Client on geotechnical matters. The Geotechnical Consultant should report his findings and recommendations to the Client or his authorized representative. The Client should be chiefly responsible for all aspects of the project. He or his authorized representative has the responsibility of reviewing the findings and recommendations of the Geotechnical Consultant. He shall authorize or cause to have authorized the Contractor and/or other consultants to perform work and/or provide services. During grading the Client or his authorized representative should remain on-site or should remain reasonably accessible to all concerned parties in order to make decisions necessary to maintain the flow of the project. The Contractor should be responsible for the safety of the project and satisfactory completion of all grading and other associated operations on construction projects, including but not limited to, earthwork in accordance with the project plans, specifications and controlling agency requirements. During grading, the Contractor or his authorized representative should remain on- site. Overnight and on days off, the Contractor should remain accessible. SITE PREPARATION The Client, prior to any site preparation or grading, should arrange and attend a meeting among the Grading Contractor, the Design Engineer, the Geotechnical Consultant, representatives of the appropriate governing authorities as well as any other concerned parties. All parties should be given at least 48 hours notice. Clearing and grubbing should consist of the removal of vegetation such as brush, grass, wood, stumps, trees, roots of trees, and otherwise deleterious natural materials from the areas to be graded. Clearing and grubbing should extend to the outside of all proposed excavation and fill areas. SG-4 Demolition should include removal of buildings, structures, foundations, reservoir, utilities (including underground pipelines, septic tanks, leach fields, seepage pits, cisterns, mining shafts, - -tunnels, etc.) and other man-made surface and subsurface improvements from the areas to be graded. Demolition of utilities should include proper capping and/or rerouting pipelines at the - project perimeter and cutoff and capping of wells in accordance with the requirements of the governing authorities and the recommendations of the Geotechnical Consultant at the time of demolition. Trees, plants or man-made improvements not planned to be removed or demolished should be protected by the Contractor from damage or injury. Debris generated during clearing, grubbing and/or demolition operations should be wasted from areas to be graded and disposed off-site. Clearing, grubbing and demolition operations should be performed under the observation of the Geotechnical Consultant. The Client or Contractor should obtain the required approvals from the controlling authorities for the project prior, during and/or after demolition, site preparation and removal, etc. The appropriate approvals should be obtained prior to proceeding with grading operations. SITE PROTECTION Protection of the site during the period of grading should be the responsibil:ty of the Contractor. Unless other provisions are made in writing and agreed upon among the concerned parties, completion of a portion of the project should not be considered to preclude that portion or adjacent areas from the requirements for site protection until such time as the entire project is complete as identified by the Geotechnical Consultant, the Client and the regulating agencies. The Contractor should be responsible for the stability of all temporary excavations. Recommendations by the Geotechnical Consultant pertaining to temporary excavations (e.g., backcuts) are made in consideration of stability of the completed project and, therefore, should be considered to preclude, the responsibilities of the Contractor. Recommendations by the Geotechnical Consultant should not be considered to preclude more restrictive requirements by the regulating agencies. Precautions should be taken 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 should be made during the rainy season to adequately direct surface drainage away from and off the work site. Where low areas can not be avoided, pumps should be kept on hand to continually remove water during periods of rainfall. During periods of rainfall, plastic sheeting should be kept reasonable accessible to prevent unprotected slopes from becoming saturated. Where necessary during periods of rainfall, the Contractor should install checkdams, desilting basins, riprap, sand bags, or other devices or methods necessary to control erosion and provide safe conditions. During periods of rainfall, the Geotechnical Consultant should be kept informed by the Contractor as to the nature of remedial preventative work being performed (e.g., pumping, placement of sand bags or plastic sheeting, or other labor, dozing, etc.). Following periods of rainfall, the Contractor should contact the Geotechmcal Consultant and arrange a walk-over of the site in order to visually assess rain related damage. The Geotechnical SG -5 I - Consultant may also recommend excavation, and testing in order to aid in his assessments. At the request of the Geotechnical Consultant, the Contractor shall make excavations in order to - -evaluate the extent of rain related damage. Rain related damage should be considered to include, but may not be limited to, erosion, silting, and saturation, swelling, structural distress and other adverse conditions identified by the Geotechnical Consultant. Soil adversely affected should be classified as Unsuitable Materials and should be subject to overexcavation and replacement with compacted fill or other remedial grading as recommended by the Geotechnical Consultant. Relatively level areas, where saturated soils and/or erosion gullies exists to depths of greater that 1 foot, should be overexcavated to unaffected, competent material. Where less than 1 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 should be overexcavated, then replaced in accordance with the applicable specifications. In slope areas, where saturated soil and/or erosion gullies exist to depths of greater than 1 foot; they should be overexcavated and replaced as compacted fill in accordance with the applicable specifications. Where affected materials exist to depths of 1 foot or less below, proposed finished grade, remedial grading by moisture conditioning in-place followed by thorough recompaction in accordance with the applicable grading guidelines herein may be attempted. If the desired results are not achieved, all affected materials should 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 Geotechnical Consultant. EXCAVATIONS Unsuitable Materials Materials, which are unsuitable, should be excavated under observation and recommendations of the Geotechnical Consultant. Unsuitable materials include, but may not be limited to, dry, loose, soft, wet, organic compressible natural soils and fractured, weathered, soft bedrock and non- engineered or otherwise deleterious fill materials Material identified by the Geotechnical Consultant as unsatisfactory due to its moisture conditions should be overexcavated, watered or dried, as needed, and thoroughly blended to a uniform near optimum moisture condition (per Moisture guidelines presented herein) prior to placement as compacted fill. Cut Slopes Unless other wise recommended by the Geotechnical Consultant and approved by the regulating agencies, permanent cut slopes should not be steeper that 2:1 (horizontal: vertical). If excavations for cut slopes expose loose, cohesionless, significantly fractured or otherwise unsuitable material, overexcavation and replacement of the unsuitable materials with a compacted stabilization fill should be accomplished as recommended by the Geotechnical SG-6 * Consultant. Unless otherwise specified by the Geotechnical Consultant stabilization fill construction should conform to the requirements of the Standard Details. The Geotechnical Consultant should review cut slopes during excavation. The Geotechnical - Consultant should be notified by the contractor prior to beginning slope excavations. If, during the course of grading, adverse or potentially adverse geotechnical conditions are encountered which were not anticipated in the preliminary report, The Geotechnical Consultant I should explore, analyze and make recommendations to threat these problems. When cut slopes are made in the direction of the prevailing drainage, a non-erodible diversion swale (brow ditch) should be provided at the top-of-cut. Pad Areas All lot pad areas, including side yard terraces, above stabilization fills or buttresses should be overexcavated to provide for a minimum of 3-feet) refer to Standard Details) of compacted fill over the entire pad area. Pad areas with both fill and cut materials exposed and pad areas containing both very shallow (less than 3-feet) and deeper fill should be overexcavated to provide for a uniform compacted fill blanket with a minimum of 3-feet in thickness (refer to Standard Details). Cut areas exposing significantly varying material types would also be overexcavated to provide for a least a 3-foot thick compacted fill blanket. Geotechnical conditions may require greater depth of over-excavation. The actual depth should be delineated by the Geotechnical Consultant during grading. For pad areas created above cut or natural slopes, positive drainage should be established away from the top-of-slope. This may be accomplished utilizing a berm and/or an appropriate pad gradient. A gradient in soil areas away from the top-of-slopes of 2 percent or greater is recommended. COMPACTED FILL All fill materials should be compacted as specified below or by other methods specifically recommended by the Geotechnical Consultant. Unless otherwise spccified, the minimum degree of compaction (relative compaction) should be 90 percent of the laboratory maximum density. Placement Prior to placement of compacted fill, the Contractor should request a review by the Geotechnical Consultant of the exposed ground surface. Unless otherwise recommended, the exposed ground surface should then be scarified (6-inches minimum), watered or dried as needed, thoroughly blended to achieve near optimum moisture conditions, then thoroughly comacted to a minimum of 90 percent of the maximum density. The review by the Geotechnical Consultant should not be considered to preclude requirements of inspection and approval by the governing agency. Compacted fill should be placed in thin horizontal lifts not exceeding 8-inches in loose thickness prior to compaction. Each lift should be watered or dried as needed; thoroughly blended to achieve near optimum moisture conditions then thoroughly compacted by mechanical methods to Ii SG-7 H1 a minimum of 90 percent of laboratory maximum dry density. Each lift should be treated in a like manner until the desired finished grades are achieved. The Contractor should have suitable and sufficient mechanical compaction equipment and watering apparatus on the job site to handle the amount of fill being placed in consideration of moisture retention properties of the materials. If necessary, excavation equipment should be "shut down" temporarily in order to permit proper compaction of fills. Earth moving equipment should only be considered a supplement and not substituted for conventional compaction equipment. When placing fill in horizontal lifts adjacent to areas sloping steeper that 5:1 (horizontal to vertical), horizontal keys and vertical benches should be excavated into the adjacent slope area. Keying and benching should be sufficient to provide at least 6-foot wide benches and minimum of 4-feet of vertical bench height within the firm natural ground, firm bedrock or engineered compacted fill. No compacted fill should be placed in an area subsequent to keying and benching until the area has been reviewed by the Geotechnical Consultant. Material generated by the benching operation should be moved sufficiently away from the bench area to allow for the recommended review of the horizontal bench prior to placement of fill. Typical keying and benching details have been included within the accompanying Standard Details. Within a single fill area where grading procedures dictate two or more separate fills, temporary slopes (false slopes) may be created. When placing fill adjacent to a false slope, benching should be conducted in the same manner as above described. At least a 3-foot vertical bench should be established within the firm core of adjacent approved compaëted fill prior to placement of additional fill. Benching should proceed in at least 3-foot vertical increments until the desired finished grades are achieved. Fill should be tested for compliance with the recommended relative compaction and moisture conditions. Field density testing should conform to ASTM Method of Test D 1557-64, D 29922- 78 and/or D 2937-71. Test should be provided for about every 2 vertical feet or 1,000 cubic yards of fill placed. Actual test intervals may vary as field conditions dictate. Fill found not to I be in conformance with the grading recommendations should be removed or otherwise handled as recommended by the Geotechnical Consultant. The Contractor should assist the Geotechnical Consultant and/or his representative by digging test pits for removal determinations and/or for testing compacted fill. As recommended by the Geotechnical Consultant, the Contractor should "shut sown" or remove grading equipment from an area being tested. The Geotechnical Consultant should maintain a plan with estimated locations of field tests. Unless the client provides for actual surveying of test locations, the estimated locations by the Geotechnical Consultant should only be considered rough estimates and should not be utilized for the purpose of preparing cross sections showing test locations or in any case for the purpose of after-the-fact evaluating of the sequence of fill placement. Moisture For field testing purposes, "near optimum" moisture will vary with material type and other ] factors including compaction procedures. "Near optimum" may be specifically recommended in Preliminary Investigation Reports and/or may be evaluated during grading. SG-8 Standard Guidelines For Grading Projects Prior to placement of additional compacted fill following an overnight or other grading delay, the exposed surface or previously compacted fill should be processed by scarification, watered or dried as needed, thoroughly blended to near-optimum moisture conditions, then recompacted to a minimum of 90 percent of laboratory maximum dry density. Where wet or other dry or other unsuitable materials exists to depths of greater than one foot, the unsuitable materials should be overexcavated. Following a period of flooding, rainfall or overwatering by other means, no additional fill should be placed until damage assessments have been made and remedial grading performed as described herein. Fill Material Excavated on-site material which are acceptable to the Geotechnical Consultant may be utilized as compacted fill, provided trash, vegetation and other deleterious materials are removed prior to placement. Where import material are required for use on-site, the Geotechnical Consultant should be notified at least 72 hours in advance of importing, in order to sample and test materials from proposed borrow sites. No import materials should be delivered for use on-site without prior sampling and testing by Geotechnical Consultant. Where oversized rock or similar irreducible material is generated during grading, it is recommended, where practical, to waste such material off-site or on-site in areas designated as "nonstructural rock disposal area". Rock placed in disposal areas should be placed with sufficient fines to fill voids. The rock should be compacted in lifts to an unyielding condition. The disposal area should be covered with at least 3 feet of compacted fill, which is free of oversized material. The upper 3 feet should be placed in accordance with the guidelines for compacted fill herein. Rocks 12 inches in maximum dimension and smaller may be utilized within the compacted fill, provided they are placed in such a manner that nesting of the rock is avoided. Fill should be placed and thoroughly compacted over and around all rock. The amount of rock should not exceed 40 percent by dry weight passing the %-inch sieve size. The 12-inch and 40 percent recommendations herein may vary as field conditions dictate. During the course of grading operations, rocks or similar irreducible materials greater than 12- inches maximum dimension (oversized material) may be generated. These rocks should not be JJ placed within the compacted fill unless placed as recommended by the Geotechnical Consultant. fl Where rocks or similar irreducible materials of greater than 122-inches but less than 4 feet of Li maximum dimension are generated during grading, or otherwise desired to be placed within an engineered fill, special handling in accordance with the accompanying Standard Details is recommended. Rocks greater than 4 feet should be broken down or disposed off-site. Rocks up to 4 feet maximum dimension should be placed below the upper 10 feet of any fill and should not be closer than 20-feet to any slop face. These recommendations could vary as locations of improvements dictate. Where practical, oversized material should not be placed below areas where structures or deep utilities are proposed. Oversized material should be placed in windrows on a clean, overexcavated or unyielding compacted fill or firm natural ground surface. Select native or imported granular soil (S.E. 30 or higher) should be placed and thoroughly flooded over and around all windrewed rock, such that voids are filled, Windrows of oversized material should be staggered so that successive strata of oversized material are not in the same vertical plane. It may be possible to dispose of individual larger rock as field conditions dictate and as recommended by the Geotechnical Consultant at the time of placement. Material that is considered unsuitable by the Geotechnical Consultant should not be utilized in the compacted fill. During grading operations, placing and mixing the materials from the cut and/or borrow areas may result in soil mixtures which possess unique physical properties. Testing may be required of samples obtained directly from the fill areas in order to verify conformance with the specifications. Processing of these additional samples may take tow or more working days. The Contractor may elect to move the operation to other areas within the project, or may continue placing compacted fill pending laboratory and field test results. Should he elect the second alternative, fill placed is done so at the Contractor's risk. Any fill placed in areas not previously reviewed and evaluated by the Geotechnical Consultant, and/or in other areas, without prior notification to the Geotechnical Consultant may require removal and recompaction at the Contractor's expense. Determination of overexcavation should be made upon review of field conditions by the Geotechnical Consultant. Fill Slopes Unless otherwise recommended by the Geotechnical Consultant and approved by the regulating agencies, permanent fill slopes should not be steeper than 2:1 (horizontal to vertical). Except as specifically recommended otherwise or as otherwise provided for in these grading guidelines (Reference Fill Materials), compacted fill slopes should be overbuilt and cut back to grade, exposing the firm, compacted fill inner core. The actual amount of overbuilding may vary as field conditions dictate. If the desired results are not achieved, the existing slopes should be overexcavated and reconstructed under the guidelines of the Geotechnical Consultant. The degree of overbuilding shall be increased until the desired compacted slope surface condition is achieved. Care should be taken by the Contractor to provide thorough mechanical compaction to the outer edge of the overbuilt slope surface. Although no construction procedure produces a slope free from risk of future movement, overfilling and cutting back of slope to a compacted inner core is, given no other constraints, the most desirable procedure. Other constraints, however, must often be considered. These constraints may include property line situations, access, and the critical nature of the development and cost. Where such constraints are identified, slope face compaction may be attempted by conventional construction procedures including backrolling techniques upon specific recommendation by the Geotechnical Consultant. SG- 10 As a second best alternative for slopes of 2:1 (horizontal to vertical) or flatter, slope construction may be attempted as outlined herein. Fill placement should proceed in thin lifts, (i.e., 6 to 8 inch loose thicknesses). Each lifts should be moisture conditioned and thoroughly compacted. The desired moisture condition should be maintained and/or reestablished, where necessary, during the period between successive lifts. Selected lifts should be tested to ascertain that desired U compaction is being achieved Care should be taken to extend compactive effort to the outer edge of the slope. Each lift should extend horizontally to the desired finished slope surface or more as needed to ultimately establish desired grades. Grade during construction should not be allowed to roll off at the edge of the slope. It may be helpful to elevate slightly the outer edge of the slope. Slough resulting from the placement of individual lifts should not be allowed to drift down over previous lifts. At intervals not exceeding 4 feet in vertical slope height or the capability of available equipment, whichever is less, fill slopes should be thoroughly backrolled utilizing a conventional sheepsfoot-type roller. Care should be taken to maintain the desired fl moisture conditions and/or reestablishing same as needed prior to backrolling. Upon achieving final grade, the slopes should again be moisture conditioned and thoroughly backrolled. The use of a side-boom roller will probably be necessary and vibratory methods are strongly recommended. Without delay, so as to avoid (if possible) further moisture conditioning, the slopes should then be grid-rolled to achieve a relatively smooth surface and uniformly compact condition. In order to monitor slope construction procedures, moisture and density tests will be taken at regular intervals. Failure to achieve the desired results will likely result in a recommendation by the Geotechnical Consultant to overexcavation the slope surfaces followed by reconstruction of the slopes utilizing overfilling and cutting back procedures and/or further attempt at the conventional backrolling approach. Other recommendations may also be provided which would be commensurate with field conditions. Where placement of fill above a natural slope or above a cut slope is proposed, the fill slope configuration as presented in the accompanying Standard Details should be adopted. For pad areas above fill slopes, positive drainage should be established away from the top-of- slope. This may be accomplished utilizing berm and pad gradients of at least 2 percent in soil areas. Off-Site Fill Off-site fill should be treated in the same manner as recommended in these specifications for site preparation, excavation, drains, compaction, etc, Off-site canyon fill should be placed in preparation for future additional fill, as shown in the accompany Standard Details. Off-site fill subdrains temporarily terminated (up canyon) should be surveyed for future relocation and connection. DRAINAGE Canyon subdrain systems specified by the Geotechnical Consultant should be installed in accordance with the Standard Details. SG- 11 LA Typical subdrains for compacted fill buttresses; slope stabilization or sidehill masses should be r. installed in accordance with the specifications of the accompanying Standard Details. H Roof, pad and slope drainage should be directed away from slopes and areas of structures to - suitable disposal areas via non-erodible devices (i.e., gutters, downspouts, concrete swales). For drainage over soil areas immediately away from structures (i.e, within 4 feet), a minimum of 4 percent gradient should be maintained. Pad drainage of at least 2 percent should be maintained over soil areas. Pad drainage may be reduced to at least 1 percent for projects where no slopes exist, either natural or man-made,' - or greater than 10-feet in height and where no slopes are planned, natural or man-made, steeper than 2:1 (horizontal to vertical slope ratio). Drainage patterns established at the time of fine grading should be maintained throughout the life fl of the project. Property owners should be made aware that altering drainage patterns could be detrimental to slope stability and foundation performance. STAKING In all fill areas, the fill should be compacted prior to the placement of the stakes. This particularly is important on fill slopes. Slope stakes should not be placed until the slope is thoroughly compacted (backrolled). If stakes must be placed prior to the completion of compaction procedures, it must be recognized that they will be removed and/or demolished at such time as compaction procedures resume. In order to allow for remedial grading operations, which could include overexcavations or slope stabilization, appropriate staking offsets should be provided. For finished slope and stabilization backcut areas, we recommend at least a 10-feet setback from proposed toes and tops-of-cut. SLOPE MAINTENANCE Landscape Plants In order to enhance surficial slope stability, slope planting should be accomplished at the completion of grading. /slope planting should consist of deep-rooting vegetation requiring little watering. Plants native to the southern California area and plants relative to native plants are generally desirable. Plants native to other semi-arid and and areas may also be appropriate. A Landscape Architect would be the best party to consult regarding actual types of plants and planting configuration. Irrigation Irrigation piper should be anchored to slope faces, not placed in trenches excavated into slope faces. Slope irrigation should be minimized. If automatic timing devices are utilized on irrigation systems, provisions should be made for interrupting normal irrigation during periods of rainfall. Through not a requirement, consideration should be given to the installation of near-surface moisture monitoring control devices. Such devices can aid in the maintenance of relatively uniform and reasonably constant moisture conditions. SG - 12 Property owners should be made aware that overwatering of slopes is detrimental to slope stability. Maintenance Periodic inspections of landscaped slope areas should be planned and appropriate measures should be taken to control weeds and enhance growth of the landscape plants. Some areas may require occasional replanting and/or reseeding. Terrace drains and downdrains should be periodically inspected and maintained free of debris. Damage to drainage improvements should be repaired immediately. Property owners should be made aware that burrowing animals could be detrimental to slope stability. A preventative program should be established to control burrowing animals. p As a precautionary measure, plastic sheeting should be readily available or kept on hand; to J protect all slope areas from saturation by periods of heavy or prolonged rainfall. This measure is strongly recommended, beginning with the period of time prior to landscape planting. Repairs If slope failures occur, the Geotechnical Consultant should be contracted for a field review of site conditions and development of recommendations for evaluation and repair. If slope failures occur as a result of exposure to periods of heavy rainfall, the failure area and currently unaffected areas should be covered with plastic sheeting to pro:ect against additional saturation. In the accompanying Standard Details, appropriate repair procedures are illustrated for superficial slope failures (i.e. occurring typically within the outer 1 foot to 3 feet of a slope face). TRENCH BACKFILL Utility trench backfill should, unless otherwise recommended, be compacted by mechanical means. Unless otherwise recommended, the degree of compaction should be a minimum of 90 percent of the laboratory maximum density. As an alternative, granular material (sand equivalent greater than 30) may be thoroughly jetted in-place. Jetting should only be considered to apply to trenches no greater than 2 feet in width and 4 feet in depth. Following jetting operations, trench backfill 3h0u1d be thoroughly mechanically compacted and/or wheel-rolled from the surface. Within slab areas, but outside the influence of foundations, trenches up to 1 foot wide and 2 feet deep may be backfihled with sand and consolidated by jetting, flooding or by mechanical means. If on-site materials are utilized, they should be wheel-rolled, tamped or otherwise compacted to a firm condition. For minor interior trenches, density testing may be deleted or spot testing may be elected if deemed necessary, based on review of backfill operations during construction. SG - 13 If utility contractors indicate that it is undesirable to use compaction equipment in close r - proximity to a buried conduit, the Contractor may elect the utilization of light weight mechanical compaction equipment and/or shading of the conduit with clean, granular material, which should be thoroughly jetted in-place above the conduit, prior to initiating mechanical compaction procedures. Other methods of utility trench compaction may also be appropriate, upon review by the Geotechnical Consultant. Clean Granular backfill and/or bedding are not recommended in slop areas unless provisions are made for a-drainage system to mitigate the potential build-up seepage forces. STATUS OF GRADING Prior of proceeding with any grading operation, the Geotechnical Consultant should be notified fl at least two working days in advance in order to schedule the necessary observation and testing Li services. Prior to any significant expansion or cut back in the grading operation, the Geotechnical J Consultant should be provided with adequate notice (i.e., two days) in order to make appropriate adjustments in observation and testing services. Following completion of grading operations and/or between phases of a grading operation, the Geotechnical Consultant should be provided with at least two working days notice in advance of commencement of additional grading operations.
