The City will not issue a construction permit until you have read and initialed your understanding of each provision in the Property Owner Acknowledgment section below and sign the form. An agent of the owner cannot execute this notice unless you, the property owner, complete the Owner's Authorized Agent form and it is accepted by the City of Carlsbad. INSTRUCTIONS: Please read and initial each statement below to acknowledge your understanding and verification of this information by signature at the bottom of the form. These are very important construction related acknowledgments designed to inform the property owner of his/her obligat ions related to the requested permit activities. I. ~I understand a frequent practice of unlicensed contractors is to have the property owner obtain an "Owner• 8uilder" building permit that erroneously implies that the property owner is providing his or her own labor and material personally. I, as an Owner-Builder, may be held liable and subject to serious financial risk for any injuries sustained by an unlicensed contractor and his or her employees while working on my property. My homeowner's insurance may not provide coverage for those injuries. I am willfully acting as an Owner-Builder and am aware of the limits of my insurance coverage for inj uries to workers on my property. II. ~I understand building permits are not required to be signed by property owners unless they are responsible for the construction and are not hiring a licensed contractor to assume this responsibility. Ill. ~I understand as an "Owner-Builder" I am the responsible party of record on the permit. I understand that I may protect myself from potential financial risk by hiring a licensed contractor and having the permit filed in his or her name instead of my own. IV. ~I understand contractors are required by law to be licensed and bonded in California and to list their license numbers on permits and contracts. V. x_1 understand if I employ or otherwise engage any persons, other than California licensed contractors, and the total value of my construction is at least five hundred dollars ($500), including labor and materials, I may be considered an "employer" under state and federal law. REV.08/20 Owner-Builder Acknow ledgement Continued VI. ~I understand if I am considered an "employer" under state and federal law, I must register with the state and federal government, withhold payroll taxes, provide workers' compensation disability insurance, and contribute to unemployment compensation for each "employee." I also understand my failure to abide by these laws may subject me to serious financial risk. VII. ~ I understand under California Contractors' State License Law, an Owner-Builder who builds single--family residential structures cannot legally build them with the intent to offer them for sale, unless all work is performed by licensed subcontractors and the number of structures does not exceed four within any calendar year, or all of the work is performed under contract with a licensed general building contractor. VIII. ~ I understand as an Owner-Builder if I sell t he property for which this permit is issued, I may be held liable for any financial or personal injuries sustained by any subsequent owner(s) which res ult from any latent construction defects in the workmanship or materials. IX. ~ I understand I may obtain more information regarding my obligations as an "employer" from the Internal Revenue Service, the United States Small Business Administration, t he California Department of Benefit Payments, and the California Division of Industrial Accidents. I also underst and I may contact the California Contractors' State License Board (CS LB) at 1-800-321-CSLB (2752) or www.cslb.ca.gov for more information about licensed cont ractors. X. ~I am aware of and consent to an Owner--Builder building permit applied for in my name, and understand that I am the party legally and financially responsible for proposed construction activity at the following address: 2624 Obelisco Place, CA, 92009 XI. ~I agree that, as the party legally and financially responsible for t his proposed construction activity, I will abide by all applicable laws and requirements that govern Owner-Builders as well as employers. XII. ~I agree to notify the issuer of t his form immediately of any additions, delet ions, or changes to any of the information I have provided on this form. Licensed contractors are regulated by laws designed to protect the public. If you contract with someone who does not have a license, the Contractor's State License Board may be unable to assist you with any financial loss you may sustain as a result of a complaint. Your only remedy against unlicensed Contractors may be in civil court. It is also important for you to understand that if an unlicensed Contractor or employee of that individual or firm is injured while working on your property, you may be held liable for damages. If you obtain a permit as Owner- Builder and wish to hire contractors, you will be responsible for verifying whether or not those contractors are properly lice nsed and the status of their workers' compensation coverage. Before a building permit can be issued, this form must be completed, signed by the property owner and returned to the City of Carlsbad Building Division. I declare under penalty of perjury that I have read and understand all of the information provided on this form and that my responses, including my authority to sign this f orm, is true and correct. I am aware that I have the option to consult with legal counsel prior to signing this form, and I have either (1) consulted with legal counsel prior to signing this form or {2} have waived this right in signing this form without the advice of legal counsel.

The findings of the investigation, laboratory test results, and recommendations for the fow1dation design are presented in this report. From a geologic and soils engineering point of view, it is our opinion that the site is suitable for the proposed development, provided the recommendations in this report are implemented during the design and construction phases. However, certain geotechnical conditions will require special consideration during the design and construction phases, as indicated by the following: • The subject property is located in an area that is relatively free of potential geologic hazards such as landsliding, liquefaction and seismically induced subsidence. The proposed development of the site will not adversely affect the adjacent property, provided the recommendations of this report are implemented during the design and construction phases • The existing rock fill and weathered metavolcanic rock are unsuitable for the support of any proposed exterior improvements, concrete tlatwork and pavement sections in their present condition. The surficial materials should be removed and replaced as properly compacted fill should any exterior improvements be considered. • The presence of relatively shallow hard rock will require special consideration in site development. Jt is anticipated that excavations into "hard rock" will experience difficult ripping. Footing excavations founded into "hard rock" will require hydraulic breakers for adequate embedmcnt. All footings should be founded into dense, competent bedrock. ... TABLE OF CONTENTS 1. INl'R(Jl)UCTl()N .......................................................... S 2.

SITE DESCRIPTION AND PROPOSED 0EVELOP:vlENT 3.1 Site Description Kara Malewicz W.O. 743821 Page 6 of26 The subject site is an existing lot located at 2624 Obelisco Place, in the City of Carlsbad. The property is an irregularly shaped lot with an existing residence in the west central portion of the property and the proposed accessory dwelling unit in the northeast portion. The general site location is detailed below, Figure 1. ; r .. l • I ... ,. ' ,;: •'. -J ,, -. . . ' p.t. ' ,_, Ar ... ... '..,,_'~ *~ ,~ ·- ... ~· II~ .<", ,,. \.\ .. • Figure 1: General Site Location _, ' -' ' ·-~" r-. . -'~ ,n lP;: "' ri'.,.. ~; y ~ COAST GEOTECH, INC. Kara Malewicz w.o. 743821 Page 7 of26 The whole extent of the pad and property is declining slightly from west to east for a total vertical descent of approximately 12 feet for approximately 180 horizontal feet. The existing pad is at an approximate elevation of 560 feet. The site is accessed through a driveway in the western side of the residence leading to an attached garage. The backyard consists of several landscaped areas. a swimming pool, several hardscape paths and a small concrete pad. A descending slope approximately I 5 r eet in height lines the eastern margin of the property. The front and back yards are highly vegetated with numerous large, mature trees, palms, plants and bushes. The site is bounded along the west by Obelisco Place, the east by Obel.isco Circle, and the north and south by existing residences. Drainage is generally by sheet flow to the east. 3. 2 Proposed Development A preliminary site plan and topography were provided by Kristin Von Z week. Architect. The project includes the construction of an accessory dwelling unit (ADU) in the northeastern portion of the property. The site plan includes a retaining wall up to approximately 7.5 feet high in the southern portion of the proposed structure. It is our understanding that a stem wall foundation is desired for the ADU due to sloping terrain. -1. SITE INVESTIGATION AND LA BORA TORY TESTING 4.1 Site Investigation Geo technical conditions of the property were evaluated by surface observations and the excavation of two (2) exploratory borings and one (l) exploratory test pit excavated with a shovel and continued with an auger boring on September 2, 2021. Borings Nos. l and 2 and Test Pit 1, designated B-1, B-2 and TP-1, were excavated in the northeast portion of the property. Drilling was impeded due to 'rock fill' and was supplemented by hand excavation. The borings and test pit were logged by our principal engineering geologist and project geologist who also retained representative soil and rock samples at selected locations and intervals for subsequent laboratory testing. Approximate borings and test pit locations are depicted on the enclosed Geotcchnical Map, Figure 2. Logs of Borings and Test Pit are included as Appendix A. Laboratory test results and engineering properties of selected samples are summarized in the following sections and in Appendix B, Laboratory Test Results. 4.2 Laboratory Testing and Analysis Earth deposits encountered in our exploratory borings were closely examined and sampled for subsequent laboratory testing. The laboratory tests were performed in accordance with the generally COAST GEOTECH, INC. Kara Malewicz w.o. 743821 Page 8 of 26 accepted American Society for Testing and Materials (ASTM) test methods or suggested procedures. All lab descriptions and results can be found in the Laboratory Test Results section of Appendix B. The following tests were performed: • Classification of Soils (ASTM D-2487) • Grain Size Analysis (ASTM D-6913) • Sedimentation Test (ASTM D-7928) • Moisture/Density (ASTM D-2216) • Maximum Dry Density and Optimum Moisture Content (ASTM D-1557) • Expansion Index Test (ASTM D-4829) Sulfate Ion Content (CTM 4 I 7) • Chloride Ion Content (CTM 422) • pH and Resistivity Test (CTM 643) • Specific Gravity Test (ASTM D-854) 5. GEOLOGIC CONDITIONS 5.1 Regional Geologic Settings The subject property is located in the Peninsular Ranges geomorphic province. The northwesterly trending mountain ranges of this province generally consist ofJurassic metamorphic rocks intruded by Cretaceous igneous rocks. During the past 54 million years, the coastal flanks of these mountainous areas have undergone several episodes of marine inundation and subsequent ref:,1Tession. This has resulted in deposition of a thick sequence of marine and nonmarine sediments on the metamorphic and igneous basement rocks. In the Mount Soledad area, these rocks have been uplifted, tilted and faulted due to activity along the Newpon-lnglewood/Rose Canyon fault zone. Further discussion of faulting in regards to the site is discussed in the Geologic Hazards section of this report 5.2 Site Geology Previously published geologic maps conducted by Tan (2002) indicate that the subject property is underlain at relatively shallow depths by Cretaceous Age Metavolcanic and Metasedimentary Rock COAST GEOTECH, INC. Kara Malewicz w.o. 743821 Page 9 of26 (Mzu). As exposed from the exploratory test pit, the site consists of, up to approximately 3.0 feet thick. of artificial fill mantling the bedrock. The end ofB-1, B-2 and TP-1 occurred at depths of2.5 feet, 2.75 feet and 3.0 feet, respectively. Geologic Cross-Section A-A' illustrating general subsurface profiles based on our exploratory test pits and exi sting site topography is attached to this report as Figure 3. A brief description of the earth materials encountered on the site follows: 1. Artificial :Fill (af): Relatively shallow !ill deposits consisting of li ght brown. fine to medium grained silty sand mantles the underlying bedrock. Numerous rock fragments were encountered in the fill. As exposed in our exploratory test pit, the fill was measured to be on the order of 2.5 feet thick in Test Pit 1 . The fill is dry to slightly moist and generally found in a moderately dense condition. 2. Bedrock (Mzu): The fill is underlain by Cretaceous age reddish to orange brown Metasedimentary and Metavolcanic Rock. The bedrock is generally found to be highly weathered and fractured in the upper 1.0 to 1 .5 feet. Below the weathered zone, the bedrock becomes dense and hard. The bedrock is dense and competent below the weathered zone and suitable for the support of foundations or structural fills. Groundwater was not encountered in any of the test pits. 5. 3 F.,xpansive Soil Based on our experience in the area and laboratory testing, the soil and bedrock reflect an expansion potential in the low range based on ASTM D4829. 5. 4 Groundwater Conditions The area has no groundwater data available. However, due to the location of the property, high groundwater conditions arc not anticipated to be a constraint to the proposed development. However, it should be noted that seepage problems can develop after completion of construction. These seepage problems most often result from drainage alterations, landscaping and over-irrigation. In the event that seepage or saturated ground does occur, it has been our experience that they are most effectively handled on an individual basis. COAST GEOTECH, INC. 6. GEOLOGIC HAZARDS 6. 1 Faulting and Seismicity Kara Malewicz w.o. 743821 Page 10 of 26 The subject site is located within the seismically active Southern California region, which is generally characterized by northwest trending, right-lateral strike-slip faults and fault zones. Several of these fault segments and zones are classified as active by the California Geologic Survey (Alquist-Priolo Earthquake Fault Zoning Act). As a result, ground shaking is a potential hazard throughout the region. Based on a review of published geologic maps, no kno""n active faults traverse the site (Figure 4). Thus, ground surface rupture is not likely to occur as a result of an earthquake or seismic event. The nearest active fault to the site is the Rose Canyon Fault Zone, located approximately 7.0 miles west of the site. It should be noted that the Rose Canyon Fault is one of four main fault strands that make up the Newport-Inglewood/Rose Canyon (NIRC) fault system (Treiman, 1984). The four strands form a series of right-stepping en echelon faults situated along the Southern California coastline. A recent study by Sahakian et al. (2017) concluded that the geometry of the NIRC fault system may enable rupture along the entire length of the fault zone. The study also modeled several rupture scenarios in light of the newly defined geometry which suggest earthquake ruptures up to magnitudes (M) of 7.4 arc possible along the NIRC system. While the models are intriguing. the paper recommends further research and modeling on the N IRC fault geometry to improve our understanding of potential hazards and ground shaking along the Southern California coast. The proximity of major faults to the site and their estimated maximum earthquake magnitudes and peak site accelerations are enclosed on Table I, and were determined by EQF A ULT version 3 .00 software (Blake, 2000).

(g) .333 .266 .214 .156 .181 .102 .083 The Rose Canyon Fault is capable of generating a magnitude earthquake which would cause strong ground motions at the subject site. Further analysis on seismicity and the site specific seismic parameters are discussed in the Recommendations section of this report and in Appendix C, Seismic Design Response Parameters. 6. 2 Landslide Potential A landslide is the displacement of a mass of rock, debris or earth down a slope caused by topographic, geological, geotcchnical and/or subsurface water conditions. Potential landslide hazards for the site were assessed using the review of published geologic and topographic maps for the area. No landslides have been mapped on or in the immediate vicinity of the subject property. The geologic conditions and the sloping terrain indicate a low to moderate potential for failure susceptibility and retreat. According to the Landslide Hazards map, Rancho Santa Fe Quadrangle (Tan and Giffen, 1995), the site is located within Susceptibility Area 3-1 where slopes are generally susceptible. COAST GEOTECH, l~C. 6.3 Liquefaction Potential Kara Malewicz w.o. 743821 Page 12 of 26 Liquefaction is a process by which a sand mass loses its shearing strength completely and flows. The temporary transformation of the material into a fluid mass is often associated with ground motion resulting from an earthquake and high groundwater conditions. Owing to the dense nature of the bedrock and the grain-size distribution, the potential for seismically-induced liquefaction and soil instability is considered low. 6. 4 Flood Potential The site is not located in the l 00-ycar flood zone according to the FEMA Flood Map Service Center (Figure 5). 6.5 Tsunami Potential Tsunamis are large sea waves generated by earthquakes, volcanic eruptions or landslides that potentially cause the displacement of substantial volumes of water. The property is not in the mapped range for the Tsunami Inundation Map for Emergency Planning (Califomia Emergency Management Agency, 2009). 7. CONCLUSIONS Based on the results from our evaluation of the site, construction of the proposed additional dwelling unit is feasible, provided the recommendations within this report arc incorporated in the design and construction of the project. The following geotechnical considerations for the project site include: • The subj ect property is located in an area that is relatively free of potential geologic hazards such as landsliding, liquefaction and seismically induced subsidence. "Ibe proposed development of the site will not adversely affect the adjacent property, provided the recommendations of this report are implemented during the design and construction phases. • The existing rock fill and weathered metavolcanic rock are unsuitable for the support of any proposed exterior improvements, concrete t1atwork and pavement sections in their present condition. The surficial materials should be removed and replaced as properly compacted fill should any exterior improvements be considered. COAST GEOTECH, INC. Kara Malewicz w.o. 743821 Page 13 of 26 • The presence of relatively shallow hard rock will require special consideration in site development. It is anticipated that excavations into "hard rock" will experience difficult ripping. Footing excavations founded into '·hard rock'. will require hydraulic breakers for adequate embedment. All footings should be founded into dense, competent bedrock. 8. RECOMMENDATIONS 8.1 Removals and Recompaction (Exterior Improvements. If Proposed) The existing rock fill and weathered bedrock for exterior improvements, concrete flatwork and pavement sections (if proposed) should be removed and replaced as properly compacted fill. The depth of removals are anticipated to be on the order of 3.0 feet. All fill should be keyed and benched into the underlying bedrock along sloping terrain. Most of the existing earth deposits are generally suitable for reuse, provided they are cleared of all organics, debris and rocks greater than 3.0 inches and thoroughly mixed. Prior to placement of the fill, the base of the removal should be observed by a representative of this firm. Additional overexcavation and recommendations may be necessary at that time. Fill should be placed in 6.0 to 8.0 inch lifts, moistened to approximately 2.0- 3 .0 percent above optimum moisture content and compacted to a minimum of 90 percent of the laboratory maximum dry density. The fill is anticipated to be composed of silty sand and rock fragments with an expansion potential in the low range. Imported fill, if necessary, should consist of non-expansive granular deposits approved by the gcotechnical engineer. 8.2 Foundations The following design parameters are based on continuous "stepped" footings founded into competent bedrock. Footings for the proposed accessory dwelling unit should be a minimum of 15 inches wide and founded a minimum of 18 inches into dense, competent bedrock for single-story and two-story structures. Isolated spread footings should be at least 24 inches square and founded a minimum of 18 inches into competent bedrock. Footing excavations founded into competent bedrock will require hydraulic breakers for adequate cmbedment. Proposed "stepped'' footing should be founded below a 2: 1 (horizontal to vertical) plane projected up from the base of the slope, a'i shown on the enclosed Cross Section A-A', Figure 3. Footings should be "stepped'" where necessary in accordance with the 2019 California Building Code (CBC) requirements (See Figure 6). A typical conduit through footing detail is provided on Figure COAST GEOTECH, INC. Kara Malcwicz w.o. 743821 Page 14 of 26 9. Please note that the depth of fill may vary across the site and additional excavation may be required to reach competent bedrock. All footings should be reinforced with a minimum of four No. 4 bars. two along the top of the footing and two along the base. Where parallel wall footings occur, the upper footing should be deepened below a 45-degree plane projected up from the base of the lower footing, or the lower wall should be designed for the additional surcharge load from the upper wall. Footing recommendations provided herein are based upon underlying soil conditions and are not intended to be in lieu of the project structural engineer's design. The base of all footings should be maintained a minimum horizontal distance of 8.0 lateral feet to the face of the nearest slope. For design purposes, an allowable bearing value of 2500 pounds per square foot may be used for foundations at the recommended footing depths for single and two story structures. For footings deeper than 18 inches, the bearing value may be increased by 250 pounds per square foot for each additional 6.0 inches of embedment to a maximum of 3500 pounds per square foot. The bearing value indicated above is for the total dead and frequently applied live loads. This value may be increased by 33 percent for short durations of loading, including the effects of wind and seismic forces. 8.3 Sulfate and Chloride Tests The results of our sulfate, chloride, pH and resistivity tests performed on representative samples are presented in Tables 6, 7 and 8, in Appendix B. The results of testing on selected samples suggest a pH of 7. 7 and the amount of water soluble chloride, in soil, is 0.016. The amount of water soluble sulfate is 0.018 percent by weight which is classified as negligible according to ACl 318 (SO Exposure Class with Not Applicable Severity). Coast Geotech, Inc. does not practice in the field of corrosion engineering. Further evaluation by a corrosive engineer may be performed if improvements that could be susceptible to corrosion are planned. COAST GEOTECH, INC. 8.4 Slabs on Grade (Inferior and Exterior. If Required) Kara Malcwicz w.o. 743821 Page 15 of 26 Slab on grade should be a minimum of 5.0 inches thick and reinforced in both directions with No. 3 bars placed 18 inches on center in both directions. Exterior slabs on grade should be a minimum of 4.5 inches thick and reinforced with No. 3 bars placed 18 inches on center in both directions. The slab should be underlain by a minimum 2.0-inch coarse sand blanket (S.E. greater than 30). Where moisture sensitive floors are used, a minimum 10.0-mil Visqueen, Stego, or equivalent moisture barrier should be placed over the sand blanket and covered by an additional two inches of sand (S.E. greater than 30). Utility trenches underl ying the slab may be backfilled with on-site materials, compacted to a minimum of 90 percent of the laboratory maximum dry density. Slabs should be reinforced as indicated above and provided with saw cuts/expansion joints, as recommended by the project structural engineer. All slabs should be cast over dense compacted subgrades. At a minimum, interior slabs should be provided with softcut contraction/control joints consisting of sawcuts spaced l O feet on center maximum each way. Cut as soon as the slab will support the weight of the saw, and operate without disturbing the final finish, which is normally within two hours after final finish at each control joint location or 150 psi to 800 psi. The softcuts shouJd be a minimum of 3/4 inch in depth, but should not exceed l inch deep maximum. Anti-ravel skid plates should be used and replaced with each blade to avoid spalling and raveling. Avoid wheeled equipment across cuts for at least 24 hours. Provide re-entrant corner (270 degree corners) reinforced for all interior slabs consisting of a minimum two, 10-foot long No. 3 bars at 12 inches on center with the first bar placed 3 inches from re-entrant comer (see Figure 7). Re-entrant corners will depend on slab geometry and/or interior column locations. Exterior slabs should be provided with weakened plane joints at frequent intervals in accordance with the American Concrete Institute (ACI) guidelines. Our experience indicates that the use of reinforcement in slabs and foundations can reduce the potential for drying and shrinkage cracking. However. some minor cracking is considered normal and should be expected as the concrete cures. Moisture barriers can retard, but not eliminate moisture vapor movement from the underlying soils up through the slab. 8.5 Lateral Resistance Resistance to lateral load may be provided by friction acting at the base of foundations and by passive earth pressure. A coefficient of friction of 0.35 may be used with dead-load forces. Design passive earth resistance may be calculated from a lateral pressure corresponding to an equivalent fluid density of 300 pounds per cubic foot with a maximum of 2500 pounds per square foot. COAST GEOTECH, INC. 8.6 Retaining Walls Kara Malewicz W.O. 743821 Page 16 of 26 Cantilever walls (yielding) retaining nonexpansive granular soils may be designed for an active-equivalent fluid pressure of 38 pounds per cubic foot for a level surcharge and 4 7 pounds per cubic foot for a sloping backfill. Restrained walls (nonyielding) should be designed for an "at-rest" equivalent fluid pressure of 60 pounds per cubic foot. Wall footings should be designed in accordance with the foundation design recommendations. All retaining walls should be provided with an adequate backdrainage system. A geocomposite blanket drain such as Miradrain 6000 or equivalent is recommended behind walls. The soil parameters assume a nonexpansive select granular backfill compacted to a minimum of 90 percent of the laboratory maximum dry density. 8. 7 Dynamic (Seismic) Lateral Earth Pressures For proposed restrained walls (non-yielding), potential seismic loading should be considered. For smooth rigid walls, Wood (1973) expressed the dynamic thrust in the following form: L\Pe = kh YJ--12 (nonyielding) where kh is ½ peak ground acceleration equal to 50 percent of the design spectral response acceleration coefficient (Sds) divided by 2.5 per C.B.C. (2007), Y is equal to the unit weight of backfill, and H is equal to the height of the wall. The pressure diagram for this dynamic component can be approximated as an inverted trapezoid with stress decreasing with depth. The point of application of the dynamic thrust is at a height of 0.6 above the base of the wall. The magnitude of the resultant is: LiPe = 17.9 H2 (nonyielding) This dynamic component should be added to the at-rest static pressure for seismic loading conditions. For cantilever walls (yielding), Seed and Whitman ( 1970) developed the dynamic thrust as: LiPe = 3/8 kh YH2 (yielding) COAST GEOTECH, INC. Kara Malewicz w.o. 743821 Page 17 of 26 The pressure diagram for this dynamic component can be approximated as an inverted trapezoid with stress decreasing with depth and the resultant at a height of 0.6 above the base of the wall. The magnitude of the resuhant is: LiPc = 6. 7 l-I2 (yielding) This dynamic component should be added to the static pressure for seismic loading conditions. 8.8 Settlement Charac/eristics Estimated total and differential settlement over a horizontal distance of 30 feet is expected to be on the order of 1.0 inch and ¾ inch, respectively. It should also be noted that long term secondary settlement due to irrigation and loads imposed by structures is anticipated to be '/4 inch. 8. 9 Seismic Considerations Although the likelihood of ground rupture on the site is remote, the property will be exposed to moderate to high levels of ground motion resulting from the release of energy should an earthquake occur along the numerous known and unknown faults in the region. The Rose Canyon Fault Zone located approximately 7.0 miles west of the property is the nearest known active fault and is considered the design fault for the site. In addition to the Rose Canyon fault, several other active faults may affect the subject site. Seismic design parameters were determined as part of this investigation in accordance with Chapter 16, Section 1613 of the 2019 California Building Code (CBC) and ASCE 7-16 Standard using the web-based United States Geological Survey (USGS) Seismic Design Tool. The generated results for the parameters are presented on Table 2. COAST GEOTECH, INC. Table 2: Seismic Design Parameters Factors Site Class Seismic Design Category Site Coefficient, Fa Mapped Short Period Spectral Acceleration, Ss Mapped One-Period Spectral Acceleration, S1 Short Period Spectral Acceleration Adjusted for Site Class, SMs Design Short Period Spectral Acceleration, Sos 8.10 Site Classification For Seismic Design Kara Malewicz w.o. 743821 Page 18 of 26 Values D II 1.121 0.947 0.346 1.062 0.708 Site soils are classified based on the upper I 00 feet maximum of site subsoil profile. In the absence of sufficient or specific site data, appropriate soil properties are permitted to be estimated by the project gcotechnical consultant based on known geotechnical conditions and Site Class Dis typicalJy used as a "default", unless otherwise noted. Site Classes A and B shall not be assigned to a site, if there is more than 10 feet of soil ( or fil I) between the top of the underlying rock surface and bottom of the foundation. Site Classes A and Bare most commonly supported by shear wave velocity determination (us, ft/s). Site Class F, which may require a site response analysis, consists of liquefiable or collapsible soils and highly sensitive clayey soil profile. Site Classes C, D, and E soils may be classified using an average field Standard Penetration Resistance (N) method for soil layers based on Section 20.4.2 of ASCE 7-16. Where refusal is met for a rock layer (blow counts of 50 or greater for 6 inches or less penetration), Ni is taken as I 00 blows per foot. Site Classification is then established based on Table 20.3-1 of ASCE 7-1 6. Requirements provided below are also applicable and should be incorporated in the project designs where appropriate: 1. Site specific hazard analysis is required (see Section 11.4.8) in accordance with Chapter 21.2 of ASCE 7-16 for structures on Site Class E sites with values of Ss greater than or equal to I .0g and structures on Site Class D and E sites with values of SI greater than or equal to 0.2g. However, COAST GEOTECH, INC. Kara Malewicz w.o. 743821 Page 19 of 26 the following 3 exceptions are pem1itted for Equivalent Lateral Force design (ELF) using conservative values of seismic design parameters in lieu of pcrfom1ing a site specific ground motion analysis: Structures on Site Class E sites with Ss greater than or equal to 1.0, provided the site coefficient Fa is taken as equal to that of Site Class C. • For structures on Site Class D sites with S I greater than or equal to 0.2, a long period coefficient (Fv) of 1. 7 may be utilized for calculation of Ts, provided that the value of Seismic Response Coefficient (Cs) is determined by Equation (12.8-2) for values of the fundamental period of the building (T) less than or equal to 1.5Ts and taken as 1.5 times the value computed in accordance with either Equation 12.8-3 for T greater than 1.5 Ts and less than or equal to TL or Equation 12.8-4 for T greater than TL. • Structures on Site Class E sites with S l greater than or equal to 0.2, provided that Tis less than or equal to Ts and the equivalent static force procedure is used for the design. 2. Where Site Class B is recommended and a site specific measurement is not provided, the site coefficients Fa, Fv, and FPGA shall be taken as unity ( 1.0) in accordance to Section 11.4.3 of ASCE 7-16. 3. Where Site Class Dis selected as the "default" site class per Section 11.4.3 of ASCE 7-16, the value of Fa shall not be less than 1.2. Where the simplified procedure of Section 12.4 is used, the value of Fa shall be determined in accordance with Section 12.14.8.1 and the values offv, SMS and SM 1 need not to be determined. At the project site, dense bedrock occurs beneath the site at depths on the order of 2.5 to 3 .0 feet below existing ground surfaces (BOS), and based on our past experience with similar deposits. Site Class D (Stiff Soil), can be conservatively considered for the project site subsoi l profile, unless otherwise noted. 8.11 Permeable Interlocking Concrete Pavers (PICP), (if Required) Permeable lnterlocking Concrete Pavers (PlCP), if proposed, should consider several design aspects. Foundations adjacent to or in close proximity to PICP should be protected by an impervious membrane extending a minimum of 5. 0 lateral feet from the foundation under the pavement section. COAST GEOTECH, INC. Kara Malewicz \V.O. 743821 Page 20 of 26 The intent is to reduce lateral migration of infiltrated drainage and potential impaction on footings. However. this approach is considered Jess desirable from a geotechnical viewpoint than lining the section with an impervious liner. Pavement underdrains are recommended and should be incorporated in the design for proper collection and disposal of filtrated storm water, as indicated on Figure 8. If subdrains are not allowed for storm water infiltration by reviewing agencies, the long term effects of infiltrated water on structural foundations and slabs cannot be predicted with any degree of certainty. PICP pavement structural section (Drivev,,.ays) should consist of 31/a inch PJCP, over a minimum of 2.0 inches of ASTM No. 8 bedding course/choke stone, over a minimum of 12 inches of ASTM No. 57 stone base course, over a minimum of 12 inches of 95 percent compacted subgrade. Bedding course/choke stone and base course stone should also be well compacted, consolidated, and interlocked (avoid crushing the underdrain pipes) with heavy construction equipment. ASTM No. 8. No. 9 or No. 89 should be used for joint materials, depending on the joint size and per manufacturer recommendations. The above stone base section may be reduced from 12 inches to a minimum of 6.0 inches for walkways and patios, if desired. The gradational requirements are summarized on Table 3. COAST GEOTECH, INC. Kara Malewicz w.o. 743821 Page 21 of 26 Table 3: Gradational Requirements for ASTM No. 57, No. 8, No. 89, and No. 9 Sieve Percent Passing Size No. 57 No. 8 No. 89 No. 9 1 ½'' 100 l" 95 to 100 ½" 25 to 60 100 100 3/e'' 85 to 100 90 to 100 100 No.4 0 to 10 l Oto 30 20 to 55 85 to 100 No. 8 0 to 5 0 to 10 5 to 30 10 to 40 No. 16 0 to 5 0 to 10 0 to 10 No. 50 0 to 5 0 to 5 8.12 Utility Trench We recommend that all utilities be bedded in clean sand to at least one foot above the top of the conduit. The bedding should be moistened and tamped in place to fill all the voids around the conduit. Imported or on-site granular material compacted to at least 90 percent relative compaction may be utilized for backfill above the bedding. Utility trench backfill within public roadways should be compacted to a minimum of 95 percent of the laboratory maximum dry density. 'Ibe invert of subsurface utility excavations paralleling footings should be located above the zone of influence of these adjacent footings. This zone of influence is defined as the area below a 45 degree plane projected down from the nearest bottom edge of an adjacent footing. This can be accomplished by either deepening the footing, raising the invert elevation of the utility, or moving the utility or the footing away from one another. 8.13 Drainage Specific drainage patterns should be designated by the project architect or engineer. However, in general, pad water should be directed away from foundations and around the structure to the street. Roof water should be collected and conducted to a suitable discharge location via non-erodible COAST GEOTECH, INC. Kara Malewicz w.o. 743821 Page 22 of 26 devices. Pad water should not be allowed to pond. Vegetation adjacent to foundations should be avoided. If vegetation in these areas is desired, sealed planter boxes or drought resistant plants should be considered. Other alternatives may be available, however. the intent is to reduce moisture from migrating into foundation subsoils. Inigation should be limited to that amount necessary to sustain plant life. All drainage systems should be inspected and cleaned annually, prior to winter rains. 8. 14 Georechnical Observations The following list of geotcchnical observations/testing is recommended during the grading and construction phases. • Observation of wall backdrainage • Density testing and observation during placement of fill and wall backfill • Laboratory testing for Maximum Dry Density and Optimum Moisture Content for each soil type used as fill Observation of footing excavations during excavation and prior to placement of steel • Utility trench observation and testing 8. 15 Plan Review A copy of the plans should be reviewed by this office, prior to initiation of construction. A copy of the foundation plans should be submitted to this office for review, prior to the initiation of construction. Additional recommendations may be necessary at that time. 8. 16 Pre-construction Meeting A pre-grading/construction meeting is recommended in order to convey concepts and recommendations to the contractors in order to reduce potential misunderstandings. 9.

General Grading should be perfom1ed to at least the minimum requirements of the local governing agencies. the California Building Code, 2019, the geotechnical report and the guidelines presented below. All of the guidelines may not apply to a specific site and additional recommendations may be necessary during the grading phase. It is the responsibility of the Contractor to adhere to these specifications, grading plans. and the provision of equipment to carry our the grading methods. 2. Site Clearing and Prep"mtio11 Trees, dense vegetation, and other deleterious materials should be removed from the site. Removal shall consist of the complete removal of roots, stumps and other buried vegetation in the areas to be excavated. Non-organic debris or concrete may be placed in deeper fill areas under direction of the Soils engineer. 3. Treatment of Existing Gro111td • All heavy vegetation. rubbish and other deleterious materials should be disposed of off site. • Materials used for compacted fill shall first be determined as suitable by the project engineer or geologist. All material with organics, rubbish or of other unsuitable composition might be considered unsuitable and shall not be used in fills. • Any pavement material in the excavation area shall be properly cleared and disposed of in an approved off-site facility or if feasible in an area on-site approved by the Project Engineer. • All surficial deposits including alluvium and colluvium should be removed unless otherwise indicated in the text of this report. Groundwater existing in the alluvial areas may make excavation difficult. Deeper removals than indicated in the text of the report may be necessary due to saturation during winter months. Subsequent to removals, the natural ground should be scarified and processed to a depth of six inches, moistened to near optimum moisture conditions and compacted to fill standards. 4. Fill Placemellf Fill placement shall be accomplished by compaction equipment such as sheepsfoot rollers, vibratory rollers and other types of equipment. The equipment should be able to properly and uniformly compact fill material to the specified relative compaction. Most site soil and bedrock may be reused for compacted fill; however, some special processing or handling may be required (see report). Highly organic or contaminated soil should not be used for compacted fill. Material used in the compacting process should be evenly spread, moisture conditioned, processed, and compacted in thin lifts not to exceed six inches in thickness to obtain a uniformly dense layer. • The fill should be placed and compacted on a horizontal plane, unless otherwise found acceptable by the Soils Engineer. • If the moisture content or relative density varies from that acceptable to the Soils engineer, the Contractor should rework the fill until it is in accordance with the following: I. Moisture content of the fill should be at or above optimum moisture as determined by ASTM D 1557. Moisture should be evenly distributed without wet and dry pockets. Pre-watering of cut or removal areas should be considered in addition to watering during fill placement, particularly in clay or dry surficial soils. If the moisture content of'the soil is below that of optimum, water shall be added by the Contractor until it reaches the specified range. 2. Each six inch layer should be compacted to at least 90 percent of the maximum density in compliance with the testing method specified by the controlling governmental agency. In this case. the testing method is ASTM Test Designation D-1557-91. • Side-hill fills should have a minimum equipment-width key at their toe excavated through all surficial soil and into competent material (see report) and tilted back into the hill. As the fill is elevated, it should be benched through surficial deposits and into competent bedrock or other material deemed suitable by the Soils Engineer. Rock fragments less than six inches in diameter may be utilized in the fill, provided: 1. They are not placed in concentrated pockets; 2. T here is a sufficient percentage of fine-grained material to surround the rocks; 3. The distribution of the rocks is supervised by the Soils Engineer. Rocks greater than six inches in diameter should be taken off site, or placed in accordance with the recommendations of the Soils Engineer in areas designated as suitable for rock disposal. In clay soil large chunks or blocks are common; if in excess of six (6) inches minimum dimension then they are considered as oversized. Sheepsfoot compactors or other suitable methods should be used to break the up blocks. The Contractor should be required to obtain a minimum relative compaction of90 percent out to the finished slope face of fill slopes. This may be achieved by either overbuilding the slope and cutting back to the compacted core, or by direct compaction of the slope face with suitable equipment. lffill slopes are built "at grade" using direct compaction methods then the slope construction should be performed so that a constant gradient is maintained throughout construction. Soil should not be "spilled" over the slope face nor should slopes be "pushed out" to obtain grades. Compaction equipment should compact each lift along the immediate top of slope. Slopes should be back rolled approximately every 4 feet vertically as the slope is built. Density tests should be taken periodically during grading on the flat surface of the fill three to five feet horizontally from the face of the slope. In addition, if a method other than over building and cuning back to the compacted core is to be employed, slope compaction testing during construction should include testing the outer six inches to three feet in the slope face to determine if the required compaction is being achieved. Finish grade testing of the slope should be perfonned after constrnction is complete. Each day the Contractor should receive a copy of the "Daily Field Report" which would indicate the results of field density tests that day or as verball y communicated to the contractor. Fill over cut slopes should be constructed in the following manner: l. All surficial soils and weathered rock materials should be removed at the cut-fill interface. 2. A key at least 1 equipment width wide (see report) and tipped at least 1 foot into slope should be excavated into competent materials and observed by the Soils Engineer or his representative. 3. The cut portion of the slope should be constructed prior to fill placement lo evaluate if stabilization is necessary, the contractor should be responsible for any additional earthwork created by placing fill prior to cut excavation. • Transition lots (cut and fill) and lots above stabilization fills should be capped with a four foot thick compacted fill blanket (or as indicated in the report). • Cut pads should be observed by the Geologist to evaluate the need for overexcavation and replacement with fill. Thi s may be necessary to reduce water infiltration into highly fractured bedrock or other permeable zones, and/or due to differing expansive potential of materials beneath a structure. The overexcavation should be at least three feet. Deeper overexcavation may be recommended in some cases. • Exploratory backhoe or dozer trenches still remaining after site removal should be excavated and filled with compacted fill if they can be located. 5. Subdrai11age • During grading, the Geologist and Soi Is Engi neer should evaluate the necessity of placing additional drains. Actual locations will be evaluated in the field. Depending on the soil and geologic conditions, additional subdrains may be necessary upon the discretion of the Geologist and Soils Engineer and per the local requirements. All subdrainage systems should be observed by the Geologist and Soils Engineer during construction and prior to covering with compacted fill. Consideration should be given to having subdrains located by the project surveyors. Outlets should be located and protected. • The final grading plans should denote the locations of the subdrains. It is the contractor's responsibility that the subdrains are installed properly and perform as expected. • 6. Utility Trench Backfill Utility trench backfill should be placed lo the following standards: • Ninety percent of the laboratory standard if native material is used as backfill. • As an alternative, clean sand may be utilized and flooded into place. No specific relative compaction would be required: however, observation. probing, and if deemed necessary, testing may be required. • Exterior trenches, paralleling a footing and extending below a I: I plane projected from the outside bottom edge of the footing, should be compacted to 90 percent of the laboratory standard. Sand backfill, unless it is similar to the inplacc fill, should not be allowed in these trench-backfill areas. • Density testing along with probing should be accomplished to verify the desired results. 7. Gmdillg Ob.'iervation and Tes-ting • Observation of the fill placement should be provided by the Soils Engineer during the progress of grading. • ln general, density tests would be made at intervals not exceeding two feet of fill height or every 1,000 cubic yards offill placed. This criteria will vary depending on soil conditions and the size of the fill. In any event, an adequate number of field density tests should be made to evaluate if the required compaction and moisture content is generally being obtained. Density tests may be made on the surface material to receive fill, as required by the Soils Engineer. All field testing should conform to the following ASTM Standards: I. ASTM Dl 556, Density of Soil In-Place By the Sand-Cone Method 2. ASTM D6938, Density of Soil and Soil Aggregate ln-Place by Nuclear Methods (Shallow Depth) • All lab testing shall conform to the following ASTM Standards: I. ASTM DI557, Moisture Density Relations of Soils and Soil-Aggregate Mixtures Using 10- Pound Hammer and 18-Inch Drop 2. ASTM D4829, Expansion Index Test Cleanouts, processed ground to receive fill, key excavations, subdrains and rock disposal should be observed by the Soils Engineer prior to placing any fill. It will be the Contractor's responsibility to notify the Soils Engineer when such areas are ready for observation. • A Geologist should observe subdrain construction. A Geologist should observe benching prior to and during placement of fill. All original existing slopes that have a gradient greater than 5: I (Horizontal:Vertical), the slope should be properly benched in accordance with the report. • (city of Carlsbad This form must be completed by the City, the applicant, and the appropriate school districts and returned to the City prior to issuing a build ing permit.
