PURPOSE AND SCOPE OF SERVICES The purpose of this study was to assess the site geotechnical conditions with regards to the proposed improvements. Services provided for this study included the following: ► Research and review of readily available geologic data and general information pertinent to the site. ► Excavation of two manual auger borings and collection of loose bulk samples for subsequent laboratory testing. ► Laboratory testing of soil samples collected during field exploration. ► Review and analysis of geologic and geotechnical engineering data. ► Compilation of this geotechnical report which presents Geo T ek's findings of pertinent site geotechnical conditions and geotechnical recommendations for site development. 2. SITE DESCRIPTION AND PROPOSED DEVELOPMENT 2.1 SITE DESCRIPTION The proposed improvement is located within the property addressed at I 081 Chestnut Avenue, Carlsbad, California 92009 (See Figure I). The property is currently improved with a single-story residence (primary dwelling), driveway, backyard, and various landscaping improvements. Property is bounded to the east, west, and south by residential property and to the north by Chestnut Avenue. This report is limited to the area of proposed improvements as discussed herein and located within the boundaries presented on the Geotechnical Map, Figure 2. The area of planned improvements (referred to herein as the "site") is located southeast of the existing primary residence in the southeast portion of the property. 2.2 PROPOSED DEVELOPMENT The proposed site improvements consist of a detached approximate I 000 square-foot single- story accessory dwelling unit (ADU). A topographic site plan provided to GeoTek in March 2023, was used as the basis for the approximate location of the exploratory borings as shown on GEOTEK SnapADU Limited Geotechnical Evaluation I 081 Chestnut Avenue, Carlsbad. CA 92008 Project No. 3758.025-SD April 28, 2023 Pa&e 2 Figure 2 (geotechnical map). The ADU is anticipated to be constructed with additional utility improvements. No additional site grading (cuts or fills to change grades) is proposed at this time. 3. FIELD STUDY AND LABORATORYTESTING 3.1 FIELD EXPLORATION The field exploration for this study was conducted on March 21 . 2023, and consisted of a site reconnaissance. excavation of two manual auger borings and collection of loose bulk soil samples for subsequent laboratory testing. A soil probe was applied at discrete depths to qualitatively evaluate the underlying soil properties. A representative from GeoTek visually logged the excavations as depicted on the Logs of Exploration. presented in Appendix A The approximate location of the test boring is presented on the Geotechnical Map, Figure 2. A rain event was occurring throughout the duration of the field exploration. 3.2 LABORATORY TESTING Laboratory tests were performed on the soil sample collected during the field exploration. The purpose of the laboratory testing was to evaluate their physical and chemical soil properties for use in engineering design and analysis. Results of the laboratory testing program. along with a brief description and relevant information regarding testing procedures, are included in Appendix B. 4. GEOLOGIC AND SOILS CONDITIONS 4.1 EARTH MA TE RIALS A brief description of the earth materials encountered during the subsurface exploration is presented in the following sections. Based on review of published geologic maps and the site- specific evaluation. the subject site is locally underlain by artificial fill over very old paralic deposits. 4.1.1 Artificial Fill (Map Symbol Af) Artificial fill was encountered in the upper foot of the subsurface exploration. Artificial fill consisted of silty fine to medium sand, dark brown in color, very moist to wet, and very loose with roots and organics in the upper 6-inches. GEOTEK SnapADU Limited Geotechnical Evaluation I 081 Chestnut Avenue. Carlsbad. CA 92008 4.1.2 Very Old Paralic Deposits (Map Symbol Qvop) Project No. 3758.025-SD April 28, 2023 Page 3 Very Old Paralic deposits were encountered underneath the artificial fill to the full depths of exploration. The paralics consisted of silty fine sand. light tan brown in color with red tints, moist to very moist, and loose to dense with depth. The paralics increased in density with depth until practical refusal was met at 3 to 5 feet below existing grades. 4.2 SURFACE AND GROUND WATER 4.2.1 Surface Water Surface water was observed during the site visit and exploration due to an ongoing rain event. If encountered during earthwork construction, surface water on this site will likely be the result of precipitation or possibly some minor surface runoff. Standing water or ponding of water was not observed. 4.2.2 Groundwater Groundwater or localized perched water was not encountered in the exploration and is not anticipated to be a factor in the proposed construction. 4.3 EARTHQUAKE AND SEISMIC HAZARDS No active or potentially active fault is known to exist at this site nor is the site situated within an "Alquist-Priolo" Earthquake Fault Zone or a Special Studies Zone (Bryant and Hart, 2007). No faults are identified on the geologic maps reviewed for the immediate proximity of the study area. The liquefaction potential and seismic settlement potential on this site are considered negligible due to the apparent density of the underlying paralics and absence of a shallow groundwater table. Evidence of ancient landslides or gross slope instabilities at this site was not observed during this study or indicated on regional geologic maps. Thus, the potential for landslides is considered negligible. GEOTEK SnapADU Limited Geotechnical Evaluation I 081 Chestnut Avenue, Carlsbad, CA 92008 Project No. 3758.025-SD April 28, 2023 Page 4 5. CONCLUSIONSAND RECOMMENDATIONS 5.1 GENERAL The proposed improvements appear feasible from a geotechnical viewpoint provided that the project design and construction comply with ordinances of the 2022 California Building Code (CBC), City of Carlsbad guidelines and recommendations contained in this report. 5.1.1 Site Clearing and Building Pad Preparation Prior to building construction, the site should be cleared of vegetation which should be properly disposed of off-site. The building pad should be reprocessed within the upper 24 inches of ground surface after clearing of surface vegetation. Reprocessing should consist of ripping/scarification to a depth of 24 inches, moisture conditioning to near optimum moisture content and compacting to a minimum 90% of maximum dry density as determined by ASTM D 1557 test procedures. If interior grade beams/foundations are designed, reprocessing of the building pad may be reduced to 12 inches. The recommended removals and recompaction should extend to at least 2 feet outside the proposed improvements, where possible. If soils are needed to raise pad grades after stripping of unsuitable materials, acceptable engineered fill materials should be placed in horizontal lifts not exceeding 8 inches in loose thickness, moisture conditioned to at or slightly above the optimum moisture content and compacted to a minimum relative compaction of 90% of maximum dry density as determined by ASTM D 1557 test procedures. In addition, after excavation of the building footings and before concrete forms and reinforcement bar has been placed, the footing bottom should be moisture conditioned to near optimum moisture content and compacted to a minimum 90% of maximum dry density as determined by ASTM D 1557 test procedures. 5.2 DESIGN RECOMMENDATIONS 5.2.1 Foundations If reprocessing of the building pad is not prepared as recommended under section 5.1 .1, the structural engineer should design an appropriate slab based on the understanding that subgrade that typically supports a slab spanning the length between footings may not perform as well as a building slab supported on fill compacted to a minimum relative compaction of 90% of maximum GEOTEK SnapADU Limited Geotechnical Evaluation I 081 Chestnut Avenue. Carlsbad. CA 92008 Project No. 3758.025-SD April 28, 2023 Pa~e 5 dry density as determined by ASTM D 1557 test procedures. The structural engineer should also design the slab and beam reinforcement based on actual loading conditions. As verified by laboratory testing, the near surface subgrade soils are considered to have a "very low" (El<20) expansion index based upon ASTM D4829 test procedures. The following criteria is for the design of the project's building foundation system. MINIMUM DESIGN REQUIREMENTS FOR CONVENTIONALLY REINFORCED FOUNDATIONS DESIGN PARAMETER "Very Low" Expansion Index (20:s;El:s;S0) Perimeter Foundation Embedment Depth 18 inches (inches below lowest adjacent finished irade) Minimum Perimeter Foundation Width 15 inches Minimum Isolated Square Foundation Width 24inches Minimum Isolated Square Foundation Depth 18 inches (inches below lowest adjacent finished irade) Minimum Slab Thickness 4inches 6"x6"-W2.9/W2.9 welded wire fabric Minimum Slab Reinforcement placed in middle of slab or No. 3 bars at 18 inch centers. Minimum Footing Reinforcement Four No. 4 Reinforcing Bars, two top and two bottom Pre-Saturation of Subgrade Soil (percent of Minimum I 00% to a depth of 12 optimum moisture content) inches It should be noted that the above recommendations are based on soil support characteristics only. The structural engineer should design the slab and beam reinforcement based on actual loading conditions. • For footings supported within suitable bearing materials, as observed and documented by a GeoTek representative, these footings may be dimensioned based on an allowable soil bearing pressure of 1,500 psf. The allowable soil bearing pressure may be increased by one-third for short term wind and/or seismic loads. • The passive earth pressure for footings within the engineered fill may be computed as an equivalent fluid having a density of I 50 psf per foot of depth, to a maximum earth pressur e GEOTEK SnapADU Limited Geotechnical Evaluation I 081 Chestnut Avenue. Carlsbad. CA 92008 Project No. 3758.025-SD April 28, 2023 Pa~e 6 of 2,500 psf. A coefficient of friction between soil and concrete of 0.25 may be used with dead load forces. When combining passive and frictional resistance, the passive pressure component should be reduced by one-third. A moisture and vapor retarding system should be placed below slabs-on-grade where moisture migration through the slab is undesirable. Guidelines for these are provided in the 2022 California Green Building Standards Code (CALGreen) Section 4.505.2, the 2022 CBC Section 1907.1 and ACI 360R-I 0. The vapor retarder design and construction should also meet the requirements of ASTM E 1643. A portion of the vapor retarder design should be the implementation of a moisture vapor retardant membrane. It should be realized that the effectiveness of the vapor retarding membrane can be adversely impacted as a result of construction related punctures (e.g. stake penetrations, tears, punctures from walking on the vapor retarder placed atop the underlying aggregate layer, etc.). These occurrences should be limited as much as possible during construction. Thicker membranes are generally more resistant to accidental puncture than thinner ones. Products specifically designed for use as moisture/vapor retarders may also be more puncture resistant. Although the CBC specifies a 6 mil vapor retarder membrane, it is Geo T ek's opinion that a minimum IO mil thick membrane with joints properly overlapped and sealed should be considered, unless otherwise specified by the slab design professional. Moisture and vapor retarding systems are intended to provide a certain level of resistance to vapor and moisture transmission thr ough the concrete, but do not eliminate it. The acceptable level of moisture transmission through the slab is to a considerable extent based on the type of flooring used and environmental conditions. Ultimately, the vapor retarding system should be comprised of suitable elements to limited migration of water and reduce transmission of water vapor through the slab to acceptable levels. The selected elements should have suitable properties (i.e., thickness, composition, strength, and permeability) to achieve the desired performance level. Moisture retarders can reduce, but not eliminate, moisture vapor rise from the underlying soils up through the slab. Moisture retarder systems should be designed and constructed in accordance with applicable American Concrete Institute, Portland Cement Association, Post- Tensioning Concrete Institute, ASTM and California Building Code requirements and guidelines. Geo Tek recommends that a qualified person, such as the flooring contractor, structural engineer, architect, and/or other experts specializing in moisture control within the building be consulted to evaluate the general and specific moisture and vapor transmission paths and associated potential impact on the proposed constr uction. That person (or persons) should provide recommendations relative to the slab moisture and vapor retarder systems and for migration of GEOTEK SnapADU Limited Geotechnical Evaluation I 081 Chestnut Avenue, Carlsbad, CA 92008 Project No. 3758.025-SD April 28, 2023 Pa~e 7 potential adverse impact of moisture vapor transmission on various components of the structures, as deemed appropriate. In addition, the recommendations in this report and Geo T ek's services in general are not intended to address mold prevention; since Geo T ek. along with geotechnical consultants in general, do not practice in the area of mold prevention. If specific recommendations addressing potential mold issues are desired. then a professional mold prevention consultant should be contacted. 5.2.2 Seismic Design Parameters The site is located at approximat ely 33.15805 Latitude and -117.337763 Longitude. Site spectral accelerations (Ss and SI), for 0.2 and 1.0 second periods for a risk targeted two (2) percent probability of exceedance in 50 years (MCER) were determined using the web interface provided by ASCE 7 Hazard Tool (https://asce7hazardtool.online/) to access the USGS Seismic Design Parameters. A Site Class "D" is deemed appropriate for this site based on the apparent density of the paralics underlying the project site. SITE SEISMIC PARAMETERS Mapped 0.2 sec Period Spectral Acceleration, S, 1.2g Mapped 1.0 sec Period Spectral Acceleration, SI 0.38g Maximum Considered Earthquake Spectral 1.44g Response Acceleration for 0.2 Second, SMs Maximum Considered Earthquake Spectral 0.97g Response Acceleration for 1.0 Second, SM1 5% Damped Design Spectral Response 0.96g Acceleration Parameter at 0.2 Second, Sos 5% Damped Design Spectral Response 0.64g Acceleration Parameter at I second, S01 Seismic Design Category D 5.2.3 Soil Sulfate C ontent The soil soluble sulfate content was determined in the laboratory for an on-site soil sample. The results indicate that the water-soluble sulfate result is 0.0 I 07 percent by weight, which is considered "negligible" per Table 4.2.1 of ACI 318. Based on the test results and Table 4.3.1 of ACI 318, no special recommendations for concrete are required for this project due to soil sulfate exposure. GEOTE K SnapADU Limited Geotechnical Evaluation I 081 Chestnut Avenue, Carlsbad, CA 92008 5.3 CONSTRUCTION OBSERVATIONS Project No. 3758.025-SD April 28, 2023 Pa~e 8 Geo T ek representatives should be present during site grading and foundation construction to check for proper implementation of the geotechnical recommendations. These representatives should perform at least the following duties: • Observe site clearing and grubbing operations for proper removal of unsuitable materials. • Observe and test bottom of removals prior to fill placement/subgrade recompaction • Evaluate the suitability of onsite and import materials for fill placement, if needed, and collect soil samples for laboratory testing where necessary. • Observe the fill for uniformity during placement. • Perform field density testing of the fill and backfill materials. • Observe and probe foundation and slab subgrade excavations to confirm suitability of bearing materials. This observation should be performed prior to placement of reinforcement. 6. INTENT It is the intent of this report to aid in the design and construction of the proposed development.

To view the BMP Manual, refer to the Engineering Standards (Volume 5). This questionnaire must be completed by the applicant in advance of submitting for a development application (subdivision, discretionary permits and/or construction permits). The results of the questionnaire determine the level of storm water standards that must be applied to a proposed development or redevelopment project. Depending on the outcome, your project will either be subject to 'STANDARD PROJECT' requirements, "PRIORITY DEVELOPMENT PROJECT (PDP) requirements or not considered a development project. This questionnaire will also determine if the project is subject to TRASH CAPTURE REQUIREMENTS. Your responses to the questionnaire represent an initial assessment of the proposed project conditions and impacts. City staff has responsibility for making the final assessment after submission of the development application. If staff determines that the questionnaire was incorrectly filled out and is subject to more stringent storm water standards than initially assessed by you, this will result in the return of the development application as incomplete. In this case, please make the changes to the questionnaire and resubmit to the city. If you are unsure about the meaning of a question or need help in determining how to respond to one or more of the questions, please seek assistance from Land Development Engineering staff.
