Geotechnical Investigation Report FOR: 906 S. Virlee, Santa Ana CA 92704
SCOPE OF WORK: Soils Report for Proposed Detached ADU, Engineer: Ayman Fouad Eskander 24881 Alicia Pkwy. St E 222 Laguna Hills CA, 92653 906 S Virlee St & #2 -
10111904212/9/2024
In accordance with the requirements of the California Building Code 1803.1.1.2. This soils report has been prepared by a registered civil engineer for the proposed project, and recommends corrective action to prevent structural damage to each dwelling. The Following is a summary of our findings, conclusions and recommendations. Site Description and Proposed Development The subject property is located on the west side of Virlee St, in the City of Santa Ana east of Harbor Blvd and west of Newhope St. A one-story house with an attached garage exists at the site. Based on the Site Plan prepared by the designer, we understand that the proposed ADU will be located in the rear yard area. Note: The rear yard area where the proposed ADU will be located is currently covered with minor grass. Note to the geotechnical report reviewer: Please see the full-scale plans prepared by the architect/designer/civil engineer which are separately submitted to the City for review, for clarifications/details of the proposed development, as needed. The site is relatively flat; and we understand that the additional raw cut/fill is not proposed for the site. Geotechincal conditions Based on the published geologic map prepared by the California Division of Mines and Geology (CDMG), the site is located within a broad flat alluvium and colluvium area. One test hole has been drilled using a small diameter auger hand-operated drilling tool down to about 5 ft deep. The approximate location of our test hole is depicted on the attached Site Plan. The geotechnical log of the test hole is included in Appendix B. Expansion index and atterberg limits test were performed, and the laboratory test results are also included in Appendix B. Based on our filed observation and testing, the near-ground surface soils at the site generally consisted of silty fine sand, damp to moist and have a very low expansion potential. It is noted that the subject site is a previously graded lot which was previously approved by the City for construction of the existing house; and the subject approved lot is also surrounded by previously approved lots where houses exist. Distress to the on-site and off-site existing houses due to deep-seated settlement of the underlying earth materials was not observed and or reported. Therefore, deep-seated settlement is not anticipated to be a problem for the proposed new structures. Therefore, drilling deeper test hole(s) substantial sampling and consolidation testing for verification of potential deep-seated settlement are not considered necessary and not performed for this project. 906 S Virlee St & #2 -
10111904212/9/2024
The lowest bearing capacity of 1,500 psf. Is recommended to be used for the proposed new structures. Therefore, direct shear testing is not considered necessary and not performed for this project. For conservative purposes, Type V cement with concrete strength of 4,500 psi is recommended to be used for concrete in contact with the on-site soils. Therefore, sulfate content testing is not considered necessary and not performed for this proposed project. Problems of the underlying soils, if any, have been previously properly treated and judged to be adequate for structural support, and approved by the City prior to construction of the existing house. In addition, for conservative purposes, remedial removal/ over-excavation and compaction of the existing soils underlying the proposed new structure is recommended for this project. Therefore, conventional laboratory tests such as moisture content & in-situ density, grain-size analysis, etc. are not considered necessary and not performed for this project. Groundwater Free standing groundwater was not encountered in our 5 ft deep test hole. Free standing ground water was not reported to be an issue at the site and in the vicinity deep footing/excavation are not proposed for the site; therefore adverse effects due to groundwater are not anticipated for the proposed development. Note: it is not anticipated; however, if wet soils are encountered, removal of the wet soil and replacement with drier soils/cement slurry can be performed. In addition, if needed crushed rock and or geogrid for bridging, etc. can also be used. This will be determined by the geotechnical consultant based on the exposed conditions during the excavations of the site. Seismicity The subject site is located in Southern California, which is a major earthquake zone. Therefore, the owner(s) of this property should be aware of the seismic associated with being located in this zone. The Soil Site Class D Default can be used for the soils underlying the subject site. The Seismic Design Category D can be used for the site. The following seismic parameters obtained from the computer program seismicmaps.org prepared by SEAOC [Structural Engineers Association California] in conjunction with California's Office of Statewide Health Planning Development [OSHPD]) in accordance with ASCE7-16 can be used for the site. ● Fa= 1.2 ● Fv=null* 906 S Virlee St & #2 -
10111904212/9/2024
● Mapped Spectral Accelerations Values: o Ss= 1.328 (for the short period of 0.2 second) o S1=0.474 (for the 1-second period) Maximum Considered Earthquake Spectral Response Accelerations: o SMs FaSs=1.593 (for the short period of 0.2 second) o SM₁ = FvS = null* (for the 1-second period) Design Spectral Response Accelerations: ● SDs= 2/3 SM,= 1.062(for the short period of 0.2 second) ● SD1 = 2/3 SM₁ = null* (for the 1-second period) ● PGA=0.568 Please see ASCE 7-16, Section 11.4.8. Please see APPENDIX C for additional seismic parameters, as needed Note: In general, the structural consultant of record for this project should review the seismic parameters provided in this report and the 2022 CBC to evaluate the seismic design. Final selection of design coefficients should be made by the structural consultant based on the local laws and ordinances, expected structure response, and the desired level of conservatism. The civil/structural design engineer should consult with the project geotechnical consultant, if additional geotechnical information is needed for structural seismic design. Faults No active faults are known to exist within or near the site. The probability of primary surface rupture or deformation at the site is, therefore, considered very low. The site is not designated to be located within the Special Studies/Earthquake Zone under the Alquist-Priolo Special Studies Act. Liquefaction Potential Based on the State of California SEISMIC HAZARD ZONES Map, Anaheim Quadrangle, the subject site is located within a potential liquefaction zone. Therefore, the owner(s) of this property should be aware of the risks associated with the potential liquefaction such as structural distress due to the potential differential settlement caused by the potential liquefaction. 906 S Virlee St & #2 -
10111904212/9/2024
Potential Consequences of Liquefaction or Secondary Liquefaction Included Hazards Potential consequences of liquefaction or secondary liquefaction included hazards generally consists of differential settlement (vertical deformations), lateral movement/lateral spreading (horizontal deformations), oscillation, and reduction in foundation soil-bearing capacity (bearing failure). A sloping condition or drainage or stream channel does not exist at the site; therefore, lateral movement/lateral spreading, oscillation, etc. due to potential liquefaction are not anticipated to be credible hazards for the proposed new structure. In general, based on our experience, differential settlement due to liquefaction (and reduction in foundation soil-bearing capacity) is roughly estimated to be about 1/4 inch (for a horizontal distance of 30 feet). Please note that this is only a rough estimate. We believe if the area would be "liquefied" in the future due to a very strong earthquake, the potential damage to the proposed new structure which will be properly structurally designed in accordance with the new up-to-date codes would be much less severe than the existing on-site structures and surrounding existing houses which have been previously structurally designed based on old codes (which are much less stringent than the current new codes). However, the owner(s) of this property should be aware of the potential damage to the new structure due to liquefaction. In summary, it should be recognized that structural mitigation may not reduce the potential of the soils to liquefy during an earthquake; and there will remain some risk that the new structure could still suffer damage if liquefaction occurs, during a very strong earthquake. Note: In accordance with the California Geological Survey (CGS), Special Publication (SP) 117A, a detailed site-specific liquefaction study is not required for this project, since the proposed new dwelling structure is not exceeding two-story and is not part of a development of four or more dwelling units. Slope Stability The site is a flat area; therefore, slope instability is not a concern for the proposed development. CONCLUSIONS AND RECOMMENDATIONS General Conclusions Construction of the proposed structure at the subject site is considered geotechnically feasible, provided the recommendations outlined in this report are implemented. Note: The conclusions and recommendations of this report are based on information as interpreted from our limited subsurface investigation. It is not anticipated but they should be 906 S Virlee St & #2 -
10111904212/9/2024
revised accordingly if geotechnical conditions to be exposed during site preparation/ grading and construction significantly differ from our findings and interpretations. In general, a conventional shallow foundation can be used for support of the proposed structure. The following recommendations are considered minimum and may be superseded by more restrictive requirements of the architect, civil/structural engineer, building codes, or governing agencies. Geotechnical Impact on Neighboring Properties Adverse geotechnical impact of the proposed development on the neighboring properties is not anticipated, provided the recommendations outlined in this report are properly implemented. Site Preparation/Grading Over-excavation / remedial removal for the proposed first-floor with slab-on-grade area: To create a relatively uniform new engineered compacted fill layer for the proposed new structural slab-on-grade area, over-excavation and re-compaction of about 3 ft. deep (measured from the existing ground surface) of the existing on-site soils should be performed. The lateral limits of the over-excavation should be minimum equal to depth of removal (3 ft. in this case) beyond the outside perimeter of the proposed new structure. The existing rear yard area where the proposed room addition will be located is currently covered with (exterior) concrete slabs which will be removed to replace with new (interior) slabs-on-grade of the proposed ADU. For the proposed new exterior concrete slabs including new driveway, if any, the over- excavation and re-compaction should be minimum 1 ft deep and 1 ft. outside of the new slab areas. Other Recommendations: The new fill/backfill soils should be free of organic matter and oversized materials, 4 inches or greater in diameter, placed in near-horizontal loose lifts not to exceed eight inches in thickness, and moisture conditioned to slightly over optimum moisture content prior to compaction. Imported soils, if any, should have a very low expansion potential and should be geotechnically observed/tested and accepted by the geotechnical consultant prior to using at the site. In general, grading at the site should be performed in accordance with the requirements of the City and under the geotechnical observation and testing of the project geotechnical consultant. The compaction criterion for fill and backfill materials is a minimum of 90% of the maximum density determined in accordance with ASTM Test Method D1557. 906 S Virlee St & #2 -
10111904212/9/2024
Temporary Excavations In general, temporary excavations should be performed in accordance with OSHA requirements. In general, care should be taken during excavation near an existing structural object, if any to ensure no damage is done to the existing object. In general, based on our experience with many similar projects in the City of Santa Ana, temporary excavation next to existing building footings does not affect the existing footings. However, if needed, excavations in sections, about 10 to 15 ft. long can be performed. This will be determined by the geotechnical engineer of record based on the conditions to be exposed during excavation. The above temporary excavation recommendations can be changed by the geotechnical consultant based on conditions to be exposed in the field during excavations BUILDING FOUNDATION DESIGN GUIDELINES Geotechnical Parameters For Structural Design For conservative purposes, the following "lowest" code values should be used for structural design, as needed. A. Allowable vertical bearing earth pressure: 1,500 psf. An increase of one-third is permitted when using the combinations that include wind or earthquake loads. B. Lateral bearing passive earth pressure: 100 psf. per foot into competent materials below the finished ground surface. An increase of one third is permitted when using the alternative load combinations that include wind or earthquake loads. C. Lateral Sliding Resistance: cohesion = 130 psf. The cohesion value is to be multiplied by the contact area. In no case shall the lateral sliding resistance exceed one-half the dead load. D. Soil unit weight: 120 pcf. New Building Footings In general, the foundation system for the proposed structure must be properly designed by the civil/structural design engineer of record for this project and reviewed and approved by the city prior to construction. The adequacy for support of the proposed structure of the existing footings should be evaluated by the civil/structural design engineer of record for this project. Underpinning footings can be provided, if needed. 906 S Virlee St & #2 -
10111904212/9/2024
New building footings should be embedded minimum 24-inches below the adjacent lowest finished grade. Minimum widths for isolated columns/pad footings, if any, should be 24-inches, and for continuous wall footings should be 12-inches for one-story and 15- inches for two story portions. Minimum reinforcement for new continuous footings should be two #5 re-bars at top and two #5 re-bars at bottom. Settlement Distress to the existing house due to settlement of the underlying soils was not observed. Therefore, deep-seated settlement of the soils underlying the site is not considered to be a concern for the proposed development. In general, based on our experience, the conventional total settlement of ½ inch and a differential settlement of ¼ inch over a horizontal distance of 30 feet are anticipated for the proposed new structure and would occur during the construction stage. New (Interior) Building Slabs-on-Grade New (interior) building slabs-on-grade should be minimum 5 inches thick, reinforced with #4 re-bars at 16 inches on centers, or equivalent, placed at mid-height of the slab. New slabs should be underlain by a 4-inch thick layer of clean sand. For moisture sensitive floor areas, the new slabs should be underlain by a 15-mil polyethylene moisture barrier membrane (such as Visqueen). The moisture barrier membrane should be properly lapped and sealed at joints and around any breaks such as openings for utility conduits. Note: CAL Green Code, and/or other applicable codes/City's requirements should govern and be followed. The entire slab-on-grade system including the capillary break / vapor/moisture retarder should be properly designed by the project civil /structural design engineer of record (but not by the geotechnical engineer) and reviewed and approved by the City prior to construction. New Exterior Slabs-on-Grade To reduce the potential for excessive cracking, new exterior concrete slabs-on-grade, if any, should be minimum 4 inches thick, provided with construction or weakened plane joints at frequent intervals (e. g., every 6 feet or less). Provision of a 2-inch thick layer of crushed rock, gravel, or clean sand to be placed beneath the slabs and/or reinforcement, such as #3 re-bars at 24 inches on-centers, or equivalent, placed at the mid-height of the slab should be considered. The subgrade soils for the exterior slabs should be properly re- compacted. Slab Subgrade Pre-Saturation The conventional pre-saturation of subgrade soils to minimum 140% of the optimum moisture content to minimum 24 inches deep is not considered necessary for this project. However, spraying with water should be performed prior to concrete pour. 906 S Virlee St & #2 -
10111904212/9/2024
Other Recommendations for Reducing Slab Cracking While not a geotechnical issue, the potential for slab cracking may also be reduced by careful control of water/cement ratio and stump of concrete. The contractor should take appropriate curing precautions during the pouring of concrete in hot weather to reduce racking of slabs. A slip sheet (or equivalent) can be utilized if grouted tile, marble tile, or other crack sensitive floor covering is planned directly on concrete slabs. New Driveway The minimum section required by the City can be used for a new driveway, if any, It there is no minimum requirements by the City, a 5-inch thick concrete slab (PCC) reinforced with #4 rebar (placed at mid-height of slaba) at 18 inches on centers both ways, or S-in. thick asphalt concrete (AC), or equivalent, over a 6-inch thick layer of aggregate base (AB) can be used. The aggregate base and subgrade should be properly compacted to a minimum of 95% and 90%, respectively, of the maximum density determined in accordance with ASTM D1557 prior to placement of the concrete slab Spraying the compacted subgrade soils with water should be performed prior to concrete pour If pavers are to be used, they must be properly designed by the civil engineer of record for this project and approved by the city prior to construction. Additional geotechnic data can be provided for design, if requested. Site Drainage In general, proper surface drainage should be checked, improved as needed, maintained to ensure surface water flows away from all structures. Requirements by city and applicable CBC (2022 CBC) should also be followed. Roof gutters should be properly provided. Roof drains, gutters and downspouts should be maintained to function as intended. Outlet drains should be kept open. Irrigation at the site, if any, should be kept to a minimum required to support plant life. In the future, sources of uncontrolled water, such as leaky sewer, water (domestic irrigation) or drainpipe, should be repaired if identified. Seismic Design We recommend the proposed new structure be structurally designed to meet applicable building codes and requirements of the controlling governmental agency. The seismic parameters provided in the "Seismicity" section of this report can be used. The civil/structural design engineer should consult with the project geotechnical consultant, if additional geotechnical information is needed for the seismic design. Cement Type For Concrete in Contact with On-Site Earth Materials 906 S Virlee St & #2 -
10111904212/9/2024
Our previous tests performed on the soils of many lots in the City of Garden Grove which are similar to the on-site soils show negligible water soluble sulfate contents. Sulfate attack on concrete was not observed for the existing on-site house and other houses in the surrounding areas. It appears sulfate attack on concrete is not a problem in the City of Garden Grove. However, for conservative purposes, Type V cement with a maximum water/cement ratio of 0.45 and a minimum concrete strength, of 4,500 psi is recommended to be used for concrete in contact with the on-site soils. Additional water- soluble sulfate content testing can be performed for the soils at the site, as needed. The test can be conducted during and/or after completion of site preparation/grading. The applicable California Building Code (2022 CBC) and other requirements by controlling governmental agencies should be followed. Corrosion To Ferrous Metals and Copper For conservative purposes, the on-site soils can be considered severely corrosive to ferrous metals and copper. Underground/buried ferrous metals or copper are not planned to be used for this project. However, if underground/buried ferrous metals or copper are planned to be used at the site, they should be properly protected. A corrosion specialist can be consulted. Testing can be performed for verification of the potential corrosion of the soils at the site to ferrous metals and copper, if needed. The test can be performed during and/or after completion of grading. Geotechnical Review of Grading and Foundation Plans Based on the City's requirements, the project geotechnical consultant should review, "approve" and sign the project grading and foundation plans with details/specifications, if any, indicating conformation to applicable geotechnical recommendations. We will cooperate with the civil/structural design engineers who prepare the plans to ensure our geotechnical recommendations are properly incorporated into the plans. Geotechnical Observation and Testing During Construction We recommend that a qualified geotechnical consultant be retained to provide geotechnical engineering services, including geotechnical observation/testing, during the construction phase of the project. This is to verify the compliance with the design, specifications and/or recommendations, and to allow design changes in the event that subsurface conditions differ from those anticipated. Geotechnical observation/testing can be performed at the following stages: ● During ANY grading operations, including excavation, removal, filling and backfilling, etc. ● During and after excavation for footings to verify the adequacy of underlying materials. ● After pre-saturation of slab subgrade earth materials, if any, prior to pouring concrete. 906 S Virlee St & #2 -
10111904212/9/2024
● After compaction of subgrade soils and/or aggregate base for exterior slabs and or driveway, if any. ● During backfill of drainage and utility line trenches, if any, to verify proper compaction. ● When/If any unusual geotechnical conditions are encountered. Note: If Geotechnical International is not provided the opportunity to perform the geotechnical observation/testing during the construction phase, Geotechnical International will take no responsibility for the conclusions and recommendations contained in our report in the event that subsurface conditions differ from those interpreted and anticipated during our preliminary investigation phase prior to the start of construction. CLOSURE The conclusion and recommendations contained in this report are presented based on geotechnical data as described herein which are believed representative of the total project area. However, earth materials can vary in characteristics, both laterally and vertically, and those variations could affect the conclusions and recommendations contained herein. As such, observation and testing by a qualified geotechnical consultant during the construction phase of the project are essential to confirming the basis of this report. This report has been prepared consistent with that level of care being provided by other professionals providing similar services at the locale and time period. The contents of this report are professional opinions and as such, are not to be considered a guaranty or warranty. This report should be reviewed and updated after a period of one year or if the lot ownership or site conditions / proposed development change from that described herein.
