Phone: 714-829-5053; Email: Tienchu.pe@gmail.com Page 3 1.0 INTRODUCTION 1.1 Purpose This report presents a summary of our preliminary geotechnical engineering investigation for the proposed development at the subject site. The purposes of this investigation were to evaluate the subsurface conditions at the area of proposed construction and to provide recommendations pertinent to grading, foundation design and other relevant parameters. 1.2 Scope of Services Our scope of services included: • Review of available soil and geologic data of the area. • Logging and sampling of hand auger boring to a maximum depth of 5 feet below the existing ground surface. Boring logs are presented in Appendix “A” (Field Investigation). • Laboratory testing of representative samples collected from the proposed construction area to establish engineering characteristics of the on-site soils. The laboratory test results are presented in Appendix B (Laboratory Testing) and on the boring logs (Appendix A). • Engineering analyses of the geotechnical data obtained from our background studies, field investigation, and laboratory testing. • Preparation of this report presenting our findings, conclusions, and recommendations for the proposed development. 1.3 Proposed Construction It is anticipated that the proposed construction is a new ADU residential with a one-story house in the rear of lot site and room addition at right side of existing house. The structure of the proposed residential building is anticipated to be one story in height. Column loads are be light. Final grade is anticipated to be near the existing grade. 1.4 Site Conditions The subject site is located at Nort side of Hazard Ave, South of Westminster Ave., West of Harbor Blvd, East of Euclid street, North of 1st Street. within a fully development area. An existing one story house with typical concrete driveway, sidewalks, rear yard. The subject site is relatively flat and is currently occupied by a residential house and a garage. No major surface erosions were observed at the time of our field investigation. TMC ENGINEERS INC. Geotechnical, Structural and Civil Engineering Add: 9542 Pacific Ave, Anaheim, CA92804. Phone: 714-829-5053; Email: Tienchu.pe@gmail.com Page 4 2.0 SUBSURFACE EXPLORATION AND LABORATORY TESTING 2.1 Subsurface Exploration Our subsurface exploration consisted of drilling hand auger boring to a maximum depth of 5 feet below the existing ground surface. Relatively undisturbed, bulk samples were collected during drilling for laboratory testing. The approximate locations of the boring are shown on the attached Site Plan. Boring logs are presented in Appendix A. 2.2 Laboratory Testing Representative samples were tested for the following parameters: Atterberg Limits, expansion index. The results of our laboratory testing along with a summary of the testing procedures are presented in Appendix B. 3.0 SUMMARY OF GEOTECHNICAL CONDITIONS 3.1 Soil Conditions Based on field observation and testing of sampler of the near ground surface soil. The ground surface soils consist of silty very fine sand. In general, these soils exist slightly moist to moist condition. 3.2 Groundwater Ground water was not encountered at a depth of about 5 feet below the existing ground surface during our subsurface investigation. Based on our review of the “Historically Highest Ground Water Contours and Borehole Log Data Locations, Anaheim and Newport Beach Quadrangle” per page # 22, it is estimated that the highest ground water level is approximate 5 feet below the existing grade. It should be noted that the CDMG ground water map is obtained by evaluating technical publications, geotechnical borehole data, water-well logs dating back to the “turn-of-the-century”. This report also indicated that ground water levels in the areas from 1960-1997 data are generally 5 to 50 feet deeper than the earlier measured data. No specific date was provided pertaining to the high ground water level. Deep footings and excavations are not proposed for this site, therefore the effect due to ground TMC ENGINEERS INC.

SEISMIC DESIGN CONSIDERATIONS Although no know active faults traverse through the subject site, like most of Southern California, the subject site lies within a seismically active area. Earthquake resistance structural design is recommended. Designing structural to be earthquake-proof is generally considered to be impractical, especially for private projects, due to cost limitations, significant damage to structures may be unavoidable during large earthquakes. The structural design of the proposed structures should be based on the 2022 California Building Code. The following minimum seismic parameter should be used: Latitude = 33.752749, Longitude = - 117.922469 Site Class: D-default Ss= 1.362 S1= 0.472 SMS= 1.326 SDS=0.884 Seismic Design Category: D This minimum code values are intended to protect life and may not provide an acceptable level of protection against significant cosmetic damage and serious economic loss. A significantly higher than code lateral design parameter would be necessary to further reduce potential economic loss during a major seismic event. Structural engineers, however, often regard higher than code values as impractical for use in structural design. The structural engineer and project owner must decide what level of risk is acceptable and to assign appropriate seismic values for use in structural design. The risk of damage to the structural due to a large earthquake cannot be totally eliminated and obtain appropriate insurance as a mitigation measure is strongly recommended. TMC ENGINEERS INC.

Based on the Seismic Hazard Zones Map, Newport Beach Quadrangle, the site is located within a potential liquefaction zone. Therefore, liquefaction may occur at the site, and the property owner(s) should be aware of the risks associated with being in a potential liquefaction zone. We recommend the proposed new structures should have a strengthened footing system as recommended in this report, and the proposed new structures will be designed based on up-to-date building codes to reduce the potential adverse effects due to potential liquefaction increasing pore-water pressure. The material will then lose strength and can flow if unrestrained, thus leading to ground failure. Liquefaction can be triggered in saturated cohesionless material by short-term cyclic loading, such as shaking due to an earthquake. Ground failure that results from liquefaction can be manifested to the proposed new structures. 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 risks that the structure could still suffer damage if liquefaction occurs during a very strong earthquake. Differential settlement due to liquefaction may occur, to reduce the potential adverse effect to the proposed new structural due to potential liquefaction induced differential settlement and/or reduction in soil bearing capacity, and it is our opinion that our recommendations shall satisfy the liquefaction requirements. 5.2 Lurching Soil lurching refers to the rolling motion on the surface due to the passage of seismic surface waves. Effects of this nature are not considered significant on the subject site where the thickness of alluvium does not vary appreciably under structures. 5.3 Surface Rupture TMC ENGINEERS INC. Geotechnical, Structural and Civil Engineering Add: 9542 Pacific Ave, Anaheim, CA92804. Phone: 714-829-5053; Email: Tienchu.pe@gmail.com Page 7 Surface rupture is a break in the ground surface during or as a consequence of seismic activity. The potential for surface rupture on the subject site is considered negligible due to the absence of known active faults at the site. 5.4 Ground Shaking Throughout southern California, ground shaking, as a result of earthquakes, is a constant potential hazard. The relative potential for damage from this hazard is a function of the type and magnitude of earthquake events and the distance of the subject site from the event. Accordingly, proposed structures should be designed and constructed in accordance with applicable portions of the building code. TMC ENGINEERS INC.

Phone: 714-829-5053; Email: Tienchu.pe@gmail.com Page 8 6.0 CONCLUSIONS Based on the results of our subsurface investigation, it is our opinion that the proposed residential development is feasible from a geotechnical standpoint, provided the recommendations contained herein are incorporated in the design and construction. The following is a summary of the geotechnical design and construction factors that may affect development of the site. 6.1 Seismicity Based on our studies on seismicity, there are no known active faults crossing the property. However, the site is located in a seismically active region and is subject to seismically induced ground shaking from nearby and distant faults, which is a characteristic of all Southern California areas. 6.2 Liquefaction Differential settlement due to liquefaction is roughly estimated to be about ¼ inch for a horizontal distance of 40 feet. Please note that this is only a rough estimate. 6.3 Groundwater Ground water was not encountered at a depth of about 5 feet below the existing ground surface during our subsurface investigation. In our opinion, groundwater will not be a problem during the near surface construction. 6.4 Expansion Potential Based on our field observation and testing of sample of the near ground surface on-site earth materials, the foundation subgrade soils at the site generally consisted of sandy soil with some sill and have a very low expansion potential.

Phone: 714-829-5053; Email: Tienchu.pe@gmail.com Page 9 7.0 RECOMMENDATIONS The following recommendations should be incorporated into the design or construction phases. 7.1 Grading 7.1.1 Site Preparation Prior to initiating grading operations, any existing vegetation, trash, debris, over-sized materials (greater than 12 inches), and other deleterious materials within fill areas should be removed from the site. 7.1.2 Surficial Soil Removals For the proposed new house, after removal of existing concrete slabs where occur and/or vegetation including roots. It is recommended that the top 2 feet thick near surface earth materials should be over-excavated and re-compacted. Removal should be extended at least 2 feet beyond building lines. No deeper removal is anticipated, however, if deeper loose soils are encountered, deeper removal and re-compaction will be required. This will be determined at the field by the project geotechnical/civil engineer, based on the actual conditions exposed at the time of site grading. The removed clean on-site earth materials without any debris, vegetation and roots can be re- used as fill or back fill material. Fill, back fill material or additional imported soils should be free of organic matter and oversize material, 6 inches or greater in diameter, placed in near-horizontal loose lift not to exceed 4 inches in thickness and moisture conditioned to slightly over optimum moisture content prior to compaction. Imported soil, if any, should have a very low expansion potential and should be geotechnical observed/tested and accepted by the geotechnical/civil engineer 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 / civil engineer. The compaction criteria for fill and backfill material is a minimum of 90% of the maximum density determined in accordance with ASTM Test Method D1557. TMC ENGINEERS INC. Geotechnical, Structural and Civil Engineering Add: 9542 Pacific Ave, Anaheim, CA92804. Phone: 714-829-5053; Email: Tienchu.pe@gmail.com Page 10 7.1.3 Structural Backfill The onsite soils may be used as compacted fill provided they are free of organic materials and debris. Fills should be placed in relatively thin lifts; brought to near optimum moisture content, then compacted to obtain at least 90 percent relative compaction based on laboratory standard ASTM D-1557-07. 7.1.4 Site Drainage Foundation and slab performance depend greatly on how well runoff waters drain from the site. This is true both during construction and over the entire life of the structure. The ground surface around structures should be graded so that water flows rapidly away from structure. Roof gutters and downspouts should be properly provided and maintained. In the future, sources of uncontrolled water, such as leaky sewer, water (domestic, irrigation) or drain pipes should be repaired if identified. The requirements of the governmental agency and the current CBC should be followed, as needed. TMC ENGINEERS INC.

Phone: 714-829-5053; Email: Tienchu.pe@gmail.com Page 11 7.2 Shallow Foundation Design 7.2.1 Allowable foundation and Lateral Pressure: Based on our field investigation and laboratory testing results. In accordance with Section 1806.2 of the 2022 California Building Code. It is recommended that the following parameters should be considered in the foundation design and construction: For conservative, the lowest values in table 1806.2, 2022 CBC Code, allowable bearing value of 1500 pounds per square foot. 7.2.2 Settlement Distress to the existing house due to settlement of the underlying soil was not observed. Settlement of soils underlying is not a concerned for the proposed development. Under construction, differential settlement between adjacent columns is not anticipated to exceed 1/4 inch for the adjacent column spaced at a distance of about 40 feet. 7.2.3 Lateral Pressures Passive earth pressure may be computed as an equivalent fluid pressure of 150 pounds per cubic foot, with a maximum earth pressure of 1500 pounds per square foot. An allowable coefficient of friction between soil and concrete of 0.3 may be used with the dead load forces. When combining passive pressure and frictional resistance, the passive pressure component should be reduced by one-third. TMC ENGINEERS INC.

Phone: 714-829-5053; Email: Tienchu.pe@gmail.com Page 12 7.2.4 Foundation Construction It is anticipated that the entire structure will be underlain by onsite soils of very low expansion potential. All new footings should be founded at a minimum depth of 24 inches below the lowest adjacent ground surface. All continuous footings should have at least two No. 4 reinforcing bars placed both at the top and two No. 4 reinforcing bars placed at the bottom of the footings. + New building footings: New continuous footings 12 inches wide at one-story, 15 inches wide at two-story. 24 inches deep at interior and exterior footings. Shallow pad footings at least 24 square inch and 24 inches deep. All continuous new footings should have at least two No. 4 reinforcing bars placed at the top and two No. 4 reinforcing bars placed at the bottom of the footings. 7.2.5 Concrete Slab Concrete slabs should be a minimum of 4 inches thick and reinforced with a minimum of No. 4 bars spacing at 18 inch both ways and its equivalent. All slab reinforcement should be supported to ensure proper positioning during placement of concrete. Concrete slabs in moisture sensitive areas should be underlain with a vapor barrier consist of a minimum of 10-mil vaper retarder with all laps sealed. A minimum of 2 inch of sand should be placed over the membrane to aid in uniform curing of concrete and 2 inch of sand under vapor barrier. Alternate per Cal Green code, a 4-inch-thick base of ½ inch or larger clean aggregate shall be provided with a 10-mil vaper retarder with all laps sealed in direct contact with concrete.

Phone: 714-829-5053; Email: Tienchu.pe@gmail.com Page 13 7.3 Temporary Trench Excavation and Backfill All trench excavations should conform to CAL-OSHA and local safety codes. All utilities trench backfill should be brought to near optimum moisture content and then compacted to obtain a minimum relative compaction of 90 percent of ASTM D-1557-07. 7.4 Nonstructural concrete Flatwork: Sidewalk and Private Driveway 4 inches (sidewalk) and 5 inch (driveway) minimum thickness reinforce concrete with # 3 at 24” on center. Crack control with saw cut or deep tool joint to a minimum of 1/3 the concrete thickness, maximum joint spacing is 5 feet (sidewalk) and 10 feet or quarter cut (driveway) whichever closer. 8.0 CORROSION POTENTIAL Sulfate attack was not observed for the existing buildings in this subjected area. Type V cement with concrete strength 3000 psi is recommended to use, Water-Cement ratio=0.5. Other requirement from government agencies, if any, can be followed. It is recommended that the subsurface soils can be corrosive to buried metal pipe. It is recommended that any underground steel utilities be blasted and given protective coating. Should additional protective measures be warranted, a corrosion specialist should be consulted. TMC ENGINEERS INC.

ADDITIONAL CONSIDERATIONS (Please refer to the appropriate section on Attachment 1 for the additional considerations listed below.) PORTIONS REMAIN IN THE SFHA STATE LOCAL CONSIDERATIONS LEVEE PROTECTED ZONE A is document provides the Federal Emergency Management Agency's determination regarding a request or a Letter of Map Amendment tor the property described above. Using the information submitted and the effective National Flood Insurance Program (NFIP) map, we have determined that the structure(s) on the property(ies) is/are not located in the SFHA, an area inundated by the flood having a 1-percent chance of being equaled or exceeded in any given year (base flood). This document amends the effective NFIP map to remove the subject property from the SFHA located on the effective NFIP map; therefore, the Federal mandatory flood insurance requirement does not apply. However, the lender has the option to continue the flood insurance requirement to protect its financial risk on the loan. This determination is based on the flood data presently available. The enclosed documents provide additional information regarding this determination. If you have any questions about this document, please contact the FEMA Mapping and Insurance eXchange (FMIX) toll free at (877) 336-2627 (877-FEMA MAP) or by letter addressed to the Federal Emergency Management Agency, LOMC Clearinghouse, 3601 Eisenhower Avenue, Suite 500, Alexandria, VA22304-6426.

Portions of this property, but not the subject of the Determination/Comment document, may remain in the Special Flood Hazard Area. Therefore, any future construction or substantial improvement on the property remains subject to Federal, State/Commonwealth, and local regulations for floodplain management. LEVEE PROTECTED (This Additional Consideration applies to the preceding 1 Property.) The subject property is located in an area protected from the 1-percent annual chance flood (base flood) by a levee or other structure subject to possible failure or overtopping by a flood larger than the base flood. ZONE A (This Additional Consideration applies to the preceding 1 Property.) The National Flood Insurance Program map affecting this property depicts a Special Flood Hazard Area that was determined using the best flood hazard data available to FEMA, but without performing a detailed engineering analysis. The flood elevation used to make this determination is based on approximate methods and has not been formalized through the standard process for establishing base flood elevations published in the Flood Insurance Study. This flood elevation is subject to change. STATE AND LOCAL CONSIDERATIONS (This Additional Consideration applies to all properties in the LOMA DETERMINATION DOCUMENT (REMOVAL)) Please note that this document does not override or supersede any State or local procedural or substantive provisions which may apply to floodplain management requirements associated with amendments to State or local floodplain zoning ordinances, maps, or State or local procedures adopted under the National Flood Insurance Program.

ADDITIONAL CONSIDERATIONS (Please refer to the appropriate section on Attachment 1 for the additional considerations listed below.) PORTIONS REMAIN IN THE SFHA STATE LOCAL CONSIDERATIONS LEVEE PROTECTED ZONE A This document provides the Fecleral Emergency Management Agency's determination regarding a request or a Letter ot Map Amendment tor the property described above. Using the information submitted and the effective National Flood Insurance Program (NFIP) map, we have determined that the structure(s) on the property(ies) is/are not located in the SFHA, an area inundated by the flood having a 1-percent chance of being equaled or exceeded in any given year (base flood). This document amends the effective NFIP map to remove the subject property from the SFHA located on the effective NFIP map; therefore, the Federal mandatory flood insurance requirement does not apply. However, the lender has the option to continue the flood insurance requirement to protect its financial risk on the loan. This determination is based on the flood data presently available. The enclosed documents provide additional information regarding this determination. If you have any questions about this document, please contact the FEMA Mapping and Insurance eXchange (FMIX) toll free at (877) 336-2627 (877-FEMA MAP) or by letter addressed to the Federal Emergency Management Agency, LOMC Clearinghouse, 3601 Eisenhower Avenue, Suite 500, Alexandria, VA 22304-6426.

Portions of this property, but not the subject of the Determination/Comment document, may remain in the Special Flood Hazard Area. Therefore, any future construction or substantial improvement on the property remains subject to Federal, State/Commonwealth, and local regulations for floodplain management. LEVEE PROTECTED (This Additional Consideration applies to the preceding 1 Property.) The subject property is located in an area protected from the 1-percent annual chance flood (base flood) by a levee or other structure subject to possible failure or overtopping by a flood larger than the base flood. ZONE A (This Additional Consideration applies to the preceding 1 Property.) The National Flood Insurance Program map affecting this property depicts a Special Flood Hazard Area that was determined using the best flood hazard data available to FEMA, but without performing a detailed engineering analysis. The flood elevation used to make this determination is based on approximate methods and has not been formalized through the standard process for establishing base flood elevations published in the Flood Insurance Study. This flood elevation is subject to change. STATE AND LOCAL CONSIDERATIONS (This Additional Consideration applies to all properties in the LOMA DETERMINATION DOCUMENT (REMOVAL)) Please note that this document does not override or supersede any State or local procedural or substantive provisions which may apply to floodplain management requirements associated with amendments to State or local floodplain zoning ordinances, maps, or State or local procedures adopted under the National Flood Insurance Program.

OWNER’S ACKNOWLEGMENT AND VERIFICATION OF INFORMATON DIRECTIONS: Read and initial each statement below to signify you understand or verify this information. _____1. I understand a frequent practice of unlicensed persons is to have the property owner obtain an “Owner -Builder” build- ing 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 person 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 injuries to workers on my prop- erty. _____2. 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. _____3. 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 o f my own. _____4. I understand Contractors are required by law to be licensed and bonded in California and to list their license numbe rs on permits and contracts. _____5. I 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. _____6. I understand if I am considered an “employer” under state and Federal law, I must register with the state and federa l government, withhold payroll taxes, provide workers’ compensation disability insurance, and contribute to unemployment com- pensation of each “employee.” I also understand my failure to abide by these laws may subject me to serious financial risk. _____7. 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 subcontrac- tors and the number of structures does not exceed four within any calendar years, or all of the work is performed under contr act with a licensed general building Contractor. _____8. I understand as an Owner-Builder if I sell the property for which this permit is issued, I may be held liable for any f inan- cial or personal injuries sustained by any subsequent owner(s) that result from any latent construction defects in the workma n- ship or materials.

It is also important for you to underst and 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 Contactors, you will be responsible for verifying whether or not those Contractors are properly licensed and the status of their workers’ compensation insurance coverage.
