I7-II06J5 INTRODUCTION This is to present the findings and conclusions of a limited geotechnical investigation for a proposed addition to the existing residence located at 2642 Sutter Street, in the City of Carlsbad, California. I The objectives of the investigation were to evaluate the existing soils conditions and recommendations for the proposed improvement. SCOPE OF SERVICES The following services were provided during this investigation: Site reconnaissance and review of published geologic, seismological and geotechnical and maps pertinent to the project area Subsurface exploration consisting of two (2) boreholes within the limits of the proposed area of improvement. The boreholes were logged by our Staff Geologist. Collection of representative soil samples at selected depths. The obtained samples were in moisture-resistant containers and transported to the laboratory for subsequent analysis. Laboratory testing of samples representative of the types of soils encountered during the field investigation Geologic and engineering analysis of the field and laboratory data, which provided the for our conclusions and recommendations Production of this report, which summarizes the results of the above analysis and presents our findings and recommendations for the proposed improvement. I SITE DESCRIPTION AND PROPOSED CONSTRUCTION The subject site is an irregular-shaped residential lot located on the north side of Sutter Strejet in the City of Carlsbad, California. A two-story house occupies the property which encompasses an area of approximately 12,740 square feet. The building pad is relatively level with desceiiding slopes to the west. Vegetation consisted of grass, shrub and a few trees. The parcel is bordered by Sutter Street to the south and similar residential developments to the remaining directions. The site plan prepared by Wright Design of Carlsbad, California indicates that the pro,ose4 construction will include an addition at the northeast corner of the existing house. it i our understanding that the addition will be two-story, wood-framed and founded on continious footings with a slab-on-grade floor. Associated improvements will include a retaining wall and other appurtenances. 3 PUN & lULl SONG CAHN/ 2642 SUTTER STREET PROJECT NO. 17-1106.15 FIELD INVESTIGATION AND LABORATORY TESTING On January 18, 2017, two (2) boreholes were excavated to a maximum depth of approximate feet below existing grade with a hand auger. The approximate locations of the boreholes are on the attached Plate No. 1, entitled "Location of Exploratory Boreholes". A continuous log soils encountered was recorded at the time of excavation and is shown on Plate No. 2 el "Summary Sheet". The soils were visually and texturally classified according to the identification procedures set forth on the attached Plate No. 3 entitled "USCS Soil Classificati Following the field exploration, laboratory testing was performed to evaluate the pen engineering properties of the foundation materials. The laboratory-testing program inc moisture and density, particle size analysis and expansion index tests. These tests were perfo in general accordance with ASTM standards and other accepted test methods. Page L-1 and No. 2 provide a summary of the laboratory test results. GEOLOGY Geologic Setting The subject site is located within the southern portion of what is known as the Peninsular Geomorphic Province of California. The geologic map pertaining to the area (Reference indicates that the site is underlain by sandstone of the Santiago Formation (Tsa). Site Stratigraphy The subsurface descriptions provided are interpreted from conditions exposed during the investigation and/or inferred from the geologic literature. Detailed descriptions of the subsi materials encountered during the field investigation are presented on the exploration logs provic Plate No. 2. The following paragraphs provide general descriptions of the encountered soil type Topsoil Topsoil is the surficial soil material that mantles the ground, usually containing roots and other oganic materials, which supports vegetation. Topsoil observed in the boreholes was approximately p-inch thick and consisted of dark brown, silty sand that was moist, loose and porous in consistency with a minor amount of organics (roots and rootlets). I Santiago Formation (Tsa) Sandstone of the Santiago Formation was underlying the topsoil. The material consisted of gray, sand with silt that was moist and dense in consistency. 4 5.0 the 6) field on PUN& YULISONGCAHN/2642 SUJTER STREET PROJECTNO. 17-1106J5 SEISMICITY Regional Seismicity Generally, Seismicity within California can be attributed to the regional tectonic movement ting place along the San Andreas Fault Zone, which includes the San Andreas Fault and most parallel and subparallel faults within the state. The portion of southern California where the subject site is loated is considered seismically active. Seismic hazards are attributed to groundshaking from earthquake events along nearby or more distant Quaternary faults. The primary factors in evaluating the effet an earthquake has on a site are the magnitude of the event, the distance from the epicenter to the site and the near surface soil profile. According to the Fault-Rupture Hazard Zones Act of 1994 (revised Aiquist-Priolo Special S Zones Act), quaternary faults have been classified as "active" faults, which show apparent s rupture during the last 11,000 years (i.e., Holocene time). "Potentially-active" faults are those with evidence of displacing Quaternary sediments between 11,000 and 1.6 million years old. Seismic Analysis Based on our evaluation, the closest known "active" fault is the Rose Canyon Fault loated approximately 9.5 kilometers (6 miles) to the west. The Rose Canyon Fault is the design fa%Ilt of the project due to the predicted credible fault magnitude and ground acceleration. The Seismicity of the site was evaluated utilizing the 2008 National Hazard Maps from the 1 website and Seed and Idriss methods for active Quaternary faults within a 50-mile radius of the si site. The site may be subjected to a Maximum Probable Earthquake of 6.9 Magnitude along the Canyon Fault, with a corresponding Peak Ground Acceleration of 0.42g. The maximum Prc Earthquake is defined as the maximum earthquake that is considered likely to occur within a 10( time period. The effective ground acceleration at the site is associated with the part of significant gound motion, which contains repetitive strong-energy shaking, and which may produce strutural deformation. As such, the effective or "free field" ground acceleration is referred to s the Repeatable High Ground Acceleration (RHGA). It has been determined by Ploessel and S1sson (1974) that the RHGA is approximately equal to 65 percent of the Peak Ground Acceleration for earthquakes occurring within 20 miles of a site. Based on the above, the calculated Crçdible RHGA at the site is 0.27g. I 2016 CBC Seismic Design Criteria A review of the active fault maps pertaining to the site indicates the location of the Rose Canyon Fault Zone approximately 9.5 km to the west. Ground shaking from this fault or one of the rnajOr active faults in the region is the most likely happening to affect the site. With respect th this hazard, the site is comparable to others in the general area. The proposed residential addition should be designed in accordance with seismic design requirements of the 2016 California gilding 5 PUN & YULI SONGCA HN/ 2642 SU17ER STREET PRO.JECTNO. 17-1106J5 Code or the Structural Engineers Association of California using the following seismic design parameters: PARAMETER VALUE 2016 CBC REFERENCE I Site Class C Table 20.3-1/ ASCE 7, Chapter 20_ Mapped Spectral Acceleration For Short Periods, S5 1.093g Figure 1613.3.1 (1) Mapped Spectral Acceleration For a 1-Second Period, S 0.421 g Figure 1613.3.1(2) Site Coefficient, Fa 1.000 Table 1613.3.3(1) - Site Coefficient, F 1.379 Table 1613.3.3(2) - Adjusted Max.

I The unlikely hazard of ground rupture should not preclude consideration of "flexible" design for on-site utility lines and connections. I Liquefaction Liquefaction involves the substantial loss of shear strength in saturated soils, usually sandy soils With a loose consistency when subjected to earthquake shaking. Based on the absence of s14a11ow groundwater and conistency of the underlying bedrock, it is our opinion that the potentil for liquefaction is very low. I Landsliding I There is no indication that landslides or unstable slope conditions exist on or adjacent to the flroject site. There are no obvious geologic hazards related to landsliding to the proposed improvenent or adjacent properties. I Tsunamis and Seiches The site is not subject to inundation by tsunamis due to its elevation and distance to the ocea4. The site is also not subject to seiches (waves in confined bodies of water). 6 PUN & YULI SONG CA HN/ 2642 SUTTER STREET PROJECTNO. 17-1106J5 GEOTECBNICAL EVALUATION Based on our investigation and evaluation of the collected information, we conclude the construction of the proposed addition is feasible from a geotechnical standpoint pro the. recommendations herein will be properly implemented during construction. In order to provide a uniform support for the addition, footings should be embedded into the sandstone of the Santiago Formation. The foundation may consist of reinforced continuous fc with conventional reinforced slabs. Recommendations and criteria for foundation design are pri in the Foundation and Slab recommendations section of this report. Compressible Soils Our field observations and testing indicate low compressibility within the dense sandstone df the Santiago Formation, which underlies the site at a shallow depth. Therefore, no remedial gradin will be required. Expansive Soils An expansion index test was performed on a representative sample of the formational soils to determine volumetric change characteristics with change in moisture content. An expansion index of 13 was obtained which indicates a very low expansion potential for the foundation soils. Groundwater Static groundwater was not encountered to the depths of the boreholes. The building pad is kcated at an elevation of approximately 170 feet above Mean Sea Level. We do not expect groundwter to affect the proposed construction. Recommendations to prevent or mitigate the effects of poor surface drainage are presented in the Drainage section of this report. CONCLUSIONS AND RECOMMENDATIONS The following conclusions and recommendations are based upon the analysis of the dath and information obtained from our soil investigation. This includes site reconnaissance; field investigation; laboratory testing and our general knowledge of the soils native to the site. The site is suitable for the proposed addition provided the recommendations set forth are implemented during construction. I The area of the proposed addition should be cleared of vegetation and deleterious matrials. Vegetation and the debris from the clearing operation should be properly disposed of off-site. The area should be thoroughly inspected for any possible buried objects, which need to be rerouted or removed prior to construction. All holes, trenches, or pockets left by the removal of these cbjects should be properly baekfilled with compacted fill materials. Based on our field investigation, dense sandstone of the Santiago Formation is underlying the area of the proposed addition at sl?àllow 7 PUN & YULI SONG CA HN/ 2642 SUTTER STREET PROJECT NO. 17-1106J5 depths. It is our opinion that this material will be adequate for support of the proposed Foundation excavations should be observed by a representative of this firm to verify c bearing soils. FOUNDATIONS AND SLABS Continuous and spread footings are suitable for use and should extend to a minimum depth bf 18 inches below the lowest adjacent grade for the proposed two-story addition into the cense sandstone of the Santiago Formation. Continuous footings should be at least 15 inches in ridth and reinforced with a minimum of four #4 steel bars; two bars placed near the top of the foctings and the other two bars placed near the bottom of the footings. New footings should be dowelled to the existing footings in accordance with the structural engineer requirements. Interior concrete slabs should be a minimum 4 inches thick. Reinforcement should consist of #3 bars placed at 16 inches on center each way within the middle third of the slabs by supporting the steel on chairs or concrete blocks "dobies". The slabs should be underlain by 2 inches of cleanj sand over a 10-mil visqueen moisture barrier. The effect of concrete shrinkage will result in cracks in virtually all-concrete slabs. To reduce the extent of shrinkage, the concrete should be placed at a maximum of 4-inch slump. The minimum steel recommended is not intended to prevent shrinkage cracks. I Where moisture sensitive floor coverings are anticipated over the slabs, the 10-mu 1astic moisture barrier should be underlain by a capillary break at least 2 inches thick, con 11 sistijg of coarse sand, gravel or crushed rock not exceeding 3/4 inch in size with no more than 5 percent passing the #200 sieve. An allowable soil bearing value of 2,000 pounds per square foot may be used for the design of continuous and spread footings at least 12 inches wide and founded a minimum of 12 inches into the dense sandstone of the Santiago Formation as set forth in the 2016 California Building fode, Table 1806.2. This value may be increased by 400 psf for each additional foot of depth or width to a maximum value of 6,000 lb/ft2. I Lateral resistance to horizontal movement may be provided by the soil passive pressure a4d the friction of concrete to soil. An allowable passive pressure of 300 pounds per square foot per foot of depth may be used. A coefficient of friction of 0.35 is recommended. The soils passive pressure as well as the bearing value may be increased by 1/3 for wind and seismic loading. SETTLEMENT Footings for the proposed two-story addition are anticipated to be supported by the dense sa of the Santiago Formation. Therefore, the total and differential settlement should be tolerable limits. 8 PUN & YULI SONGCAHN/ 2642 SUTTER STREET PROJECTNO. 17-1106J5 TEMPORARY SLOPES Excavations for foundations or on-site utility trenches may be made vertically for shallow dpths and must be either shored or sloped at 1H: 1V for depths greater than 4 feet; OSHA guidelines for trench excavation safety should be observed during construction. PERMANENT SLOPES Permanent cut and fill slopes are less than 15 feet in height and constructed no steeper than 21.: IV slope ratios. These slopes are anticipated to be grossly stable following construction of the addition. It is recommended that the existing drought resistant vegetation be maintained to enlance the stability of the slope surfaces. RETAINING WALLS Cantilevered retaining walls should be designed for an "active" lateral earth pressure of 35 ps'çt (35 pcf EFP) for approved granular backfill and level backfill conditions. Where cantilevered walls support 2:1 (hor:vert) sloping backfill, the equivalent active fluid pressure should be increased io 45 pcf. Cantilever walls subject to uniform surcharge loads should be designed for an additional uniform lateral pressure equal to one-third (1/3) the anticipated surcharge pressure. Restrained walls such as basement walls should be designed utilizing an "at-rest" earth pressure 'pf 60 psf/ft (60 pcf EFP) for approved granular and level backfill. Restrained walls subject to uniform surcharge loads should be designed for an additional uniform lateral pressure equal to onehalfJ (1/2) the anticipated surcharge. For earthquake motions, additional lateral pressures of 24 pcf (EFP) and 36 pcf (EFP) for nonrestrained and restrained conditions respectively may be applied using an inverted triangular distribution if required. I Retaining wall footings should be embedded a minimum of 12 inches below the lowest adjacent grade. Retaining walls that are located on slopes should be designed to allow a minimum daylight di 'cc of 7 feet laterally from the outside edge of the footing to the slope face. I Soil design criteria, such as bearing capacity, passive earth pressure and sliding resistane as recommended under the Foundation and Slab recommendations section, may be incorporated into the retaining wall design. Footings should be reinforced as recommended by the structural engineer and appropriate back drainage provided to avoid excessive hydrostatic wall pressures. As a minimum we recommend a fabric-wrapped crushed rock and perforated pipe system. At least 2 cubic feet per linear foot o4 free- drainage crushed rock should be provided. The remaining wall backfill should consist of approved granular material. This fill material shoild be compacted to a minimum relative compaction of 90 percent as determined by ASTM D-1557 test method. Flooding or jetting of backfill should not be permitted. Granular backfill should be capp, ed with a minimum 18 inches of relatively impervious fill to seal the backfill and prevent saturatio4 rJ PUN & YULI SONG CA uN! 2642 SUTTER STREET PROJECTNO. 17-1106J5 It should be noted that the use of heavy compaction equipment in close proximity to retaining structures can result in wail pressures exceeding design values and corresponding wall movement greater than that associated with active or at-rest conditions. In this regard, the contractor should take appropriate precautions during the backfill placement. TRENCH BACKFILL Excavations for utility lines, which extend under structural areas should be properly backfihled and compacted. Utilities should be bedded and backfihled with clean sand or approved granular 4i1 to a depth of at least one foot over the pipe. This backfill should be uniformly watered and compacted to a firm condition for pipe support. The remainder of the backfill should be on-site soils orjnon- expansive imported soils, which should be placed in thin lifts, moisture-conditioned and compacted to at least 90% relative compaction. DRAINAGE Adequate measures should be undertaken after the new structure and other improvements 4re in place, such that the drainage water within the site and adjacent properties is directed away from the foundations, footings, floor slabs and the tops of slopes via rain gutters, downspouts, surface sfraies and subsurface drains towards the natural drainage for this area. In accordance with the 2016 California Building Code, a minimum gradient of 2 percent is recommended in hardscape areas adjacent to the structure. In earth areas, a minimum gradient of 5 percent away from the structure for a distance of at least 10 feet should be provided, if this requirement cannot be met due t6 site limitations, drainage can be done through a swale in accordance with Section 1804.4 of the 12016 California Building Code. Earth swales should have a minimum gradient of 2 percent. Drinage should be directed to approved drainage facilities. Proper surface and subsurface drainage ill be required to minimize the potential of water seeking the level of the bearing soils under the foundations, footings and floor slabs, which may otherwise result in undermining and differiniaI settlement of the structure and other improvements. I FOUNDATION PLAN REVIEW The foundation plan and details should be reviewed by our firm during the design phase to assure conformance with the intent of this report. During construction, foundation excavations shold be observed by our representative prior to the placement of forms, reinforcement or concrete for conformance with the plans and specifications.
