Box 1195 Lakeside, California 92040 (619} 443-0060 In accordance with your request, a Site Inspection has been performed at the subject site. The purpose of this investigation was to examine existing site conditions and provide engineering recommendations for the proposed addition to the existing single family residence. If project details vary significantly from those described, Soil Testers should be notified prior to final submittal for revision and possible revision of the recommendations presented herein This report is issued with the understanding that it is the responsibility of the owner or the owner's representative to ensure that the information and recommendations contained herein are brought to the attention of the architect and engineer for the project and incorporated into the plans, and the necessary steps are taken to see that the contractor and subcontractors carry out such recommendations in the field. FIELD INSPECTION In order to accomplish this purpose, a representative of this finn visited the site, reviewed the topography and site conditions and visually and textually classified the surface and near surface soils. Representative samples of the on-site soils were obtained from a test exploration approximately 3 feet in depth and tested for density and expansive characteristics. 1 Hamro Construction File No. 110614-22 January 9, 2023 SITE CONDfflONS The subject site is located on the southerly side of Victoria Avenue. The property is relatively level previously graded lot with an existing two story single family residence. The street is gently sloping with the house to the east slightly higher and the house to the west slightly lower in elevation. Neighboring properties are occupied by single family residential structures. Fill materials were encountered to a depth of approximately 20 inches during the course of this inspection. SOIL CONDIDONS Soils encountered in the test exploration are topsoils consisting of loose, brown, sandy loam to approximately 8 inches in depth underlain by fill soils consisting of firm, grey, sandy, silty clays to approximately 12 inches where medium dense to dense, orange-brown, clayey sands were encountered approximately 20 inches in depth. Native soils consisting of dense, grey, silty cemented sands were encountered to the bottom of the test exploration approximately 3 feet in depth. Some of the soils we encountered were considered to be moderately expansive with respect to change in volume with change in moisture content. CONCLUSIONS AND RECOMMENDATIONS 1. A representative sample of the foundation soil was remolded to 90% of maximum dry density. Based on the following test results, a safe allowable bearing value of at least 2000 pounds per square foot for 12 inch deep footings may be used in designing the foundations and slab for the proposed structures. This value may be increased by one third for wind and/or seismic loading. This value may be increased by 20 percent for each additional foot of depth and or width to a maximum of 3 times the designated value. Sample #1 Maximum Dry Density Optimum Moisture Expansion Index 125.6 pcf 10.4% 51 2. Lateral resistance to horizontal movement may be provided by the soil passive pressure and friction of concrete to soil. An allowable passive pressure of 250 pounds per square foot per foot of depth may be used. A coefficient of friction of 0.35 is recommended. The soils passive pressure may be increased by 1/3 for wind and seismic loading. 2 Hamro Construction File No. 110614-22 January 9, 2023 3. For the proposed addition to the footprint of the existing house, to prevent differential settlement, the footings excavations should extend an additional 18 inches below approved footing depth. A suitable backfill material should be compacted to a minimum of95% relative compaction or a 3 sack slurry with 8" slump may be used to back fill the bottom of the footing excavations up the approved footing depth. The slab preparation recommendations presented in #6 must be adhered to. 4. A representative of this company must inspect the slab preparation and the foundation excavations prior to placement of forms and reinforcing steel to ensure that adequate depth has been achieved. S. The foundation soils are moderately expansive. The following foundation depth is a minimum due to the expansive nature of the soil and must be used in order to prevent possible damage to the proposed structures from adverse effects of expansive soils. These recommendations for footings and slabs are based upon the soil type only and do not take into consideration the structural requirements. In general, the bottom of footing excavations should be founded in a uniform soil. ■ Use continuous exterior perimeter foundations (including door openings). They should be founded a minimum of 18 inches below lowest adjacent grade. ■ Interior footing depth should exceed 12 inches below top of slab or 12 inches below lowest adjacent grade for raised floor construction. ■ Reinforce continuous concrete foundations as a beam with at least one #5 bar positioned 3 inches above the bottom of footing and one #5 bar positioned at least 1 inch below top of foundation or top of finish floor. Footings deeper than 24 inches should have an additional #5 steel bar for each additional foot of depth. In lieu of one #5 bar, two #4 bars may be used. 6. Concrete Slab-On-Grade, SOG for proposed structures, should be designed by the project's structural engineer based on anticipated loading conditions. We recommend that conventional reinforced concrete SOG for this project be founded on 4 inches of Class II Virgin Aggregate Base (with approximately 2% +/-over optimum moisture content and 90% compaction, relative to the lab maximum dry density, ASTM D 1557), overlying a 12 inch thick zone of adequately placed and compacted structural fill. 3 Hamro Construction File No. 110614-22 January 9, 2023 We recommend that a moisture barrier be provided by a membrane, visqueen 10 mils in minimum thickness or equivalent, be placed at top of well compacted Class II Aggregate Base, then covered with 2 inches of moist clean sand having a minimum sand equivalent of 30 when tested in accordance with the American Society of Testing and Materials test method 'ASTM D2419. Floor slabs, as a minimum, should be 5 inches thick with #4 reinforcing steel at 16" on-center each way. Reinforcement should be placed at mid-height of the slab. The final slab thickness and reinforcement should be determined by the structural design engineer. Control joints should be provided in accordance with the recommendations of the structural design engineer. SITE EROSION CONTROL During construction, surface water should be controlled via berms, gravel bags and/or sandbags, silt fence, straw wattles, siltation basins, or other methods to avoid damage to the finish work or adjoining properties, while maintaining positive surface grades. All site entrances and exits must have coarse gravel or steel shaker plates to minimize offsite sediment tracking. Best management Practices (BMP's) must be used to protect storm drains and minimize pollution. The contractor should take measures to prevent erosion of graded areas until such time as permanent drainage and erosion control measures have been installed. After completion of grading, all excavated surfaces should exhibit positive drainage and eliminate areas where water might pond. SITE AND SURFACE DRAINAGE Drainage at the site should be directed away from foundations, collected and tight lined to appropriate discharge points. Consideration may be given to collecting roof drainage by eave gutters and directing it away from foundations via non-erosive devices. Water, either natural or from irrigation, should not be permitted to pond, saturate the surface soils or flow towards the foundation. Landscaping requiring a heavy irrigation schedule should not be planted adjacent to foundations or paved areas. The type of drainage issues found within the project and materials specified and used should be determined by the Engineer of Record. GROUNDWATER AND SURFACE WATERS There was no indication of a near-surface groundwater table or perched groundwater within the depths of our test exploration. Although groundwater is not expected to be a significant constraint to the proposed development, our experience indicates that near- surface groundwater conditions can develop in areas where no such groundwater 4 Hamro Construction File No. 1106J4-22 January 9, 2023 conditions previously existed, especially in areas where a substantial increase in surface water infiltration results from landscape irrigation or unusually heavy precipitation. It is anticipated that site development will include appropriate drainage provisions for control and discharge of surface water runoff. The type of drainage issues found within the project and materials specified and used should be determined by the Civil Engineer. The type of plants and soil specified along with proper irrigation used should be determined by the Landscape Architect. The following grading specifications should be utilized if grading is proposed. RECOMMENDED GRADING SPECIFICATIONS For Proposed Residential Building Site 2739 Victoria A venue City of Carlsbad GENERAL: Soil Testers and 'Engineer' are synonymous hereinafter and shall be employed to inspect and test earthwork in accordance with these specifications, the accepted plans, and the requirements of any jurisdictive governmental agencies. They are to be allowed adequate access so that the inspections and tests may be performed. The Engineer shall be apprised of schedules and any unforeseen soil conditions. Substandard conditions or workmanship, inadequate compaction, adverse weather, or deviation from the lines and grades shown on the plans, etc., shall be cause for the engineer to either stop construction until the conditions are corrected or recommend rejection of the work. Refusal to comply with these specifications or the recommendations and/or interpretations of the engineer will be cause for the engineer and/or his representative to immediately terminate his services. A pre-construction meeting or conference with the developer, contractor, civil engineer, soil engineer, and the agency inspector in attendance should be held at the site prior to the beginning of the grading operations. Special soil handling requirements can be discussed at that time. Grading of the site should commence with the removal of all vegetation and existing improvements from the area to be graded. Deleterious material and debris such as broken asphalt and concrete, underground pipe materials, wires, trash, etc. if encountered, should be exported from the site and should not be mixed with the fill soils. 5 Hamro Construction File No. 110614-22 January 9, 2023 Abandoned foundations and buried septic tanks or cisterns (if encountered) should be removed and the subsequent depressions and /or trenches should be filled with properly compacted materials as part of the remedial grading. All fill and backfill soils should be placed in horizontal loose layers approximately 8 inches thick, moisture conditioned to a water content of one to three percent above optimum moisture content, and compacted to at least 90 percent relative compaction, as determined by ASTM Test Method D 1557-00. The excavation bottom should then be scarified to a depth of approximately 6 to 8 inches, moisture-conditioned to 1 to 3 percent above optimum moisture content, and re- compacted to a minimum relative compaction of 90 percent in accordance with ASTM D D1556 or D6938 -17ael. Excavated sandy or clayey soils should then be uniformly moisture conditioned at above optimum moisture content, placed in 8-inch-thick loose layers and compacted to a relative compaction of at least 90 percent. Import fill soil, if required, should consist of granular materials with low expansion potential (El less than 50 or stated by the soil engineer) and should be compacted as indicated herein. Soil Testers should be notified of the import source and should perform laboratory testing of the soil prior to its arrival at the site to determine its suitability as fill material. Deviations from the recommendations of the Soil Report, from the plans, or from these Specifications must be approved in writing by the owner and the contractor and endorsed by the engineer. son, TEST METHODS: Maximum Density & Opt Moisture Density of Soil In-Place --ASTM Dl557-70 --ASTM D1556, D2922 and D3017 Soil Expansion Shear Strength Gradation & Grain Size Capillary Moisture Tension Organic Content --UBC STANDARD 29-2 --ASTM D3080-72 --ASTM D 1140-71 --ASTM D2325-68 --% Weight loss after heating for 24 hours at 3 00° F and after deducting soil moisture. LIMITING SOIL CONDITIONS: Minimum Compaction 90% for 'disturbed' soils.

Expansion index exceeding 20 Less than 40% passing the #4 sieve. Rocks over 6" in diameter. PREPARATION OF AREAS TO RECEIVE FILL: January 9, 2023 Brush, trash, debris and detrimental soils shall be cleared from the areas to receive fill. Detrimental soils shall be removed to firm competent soil. Slopes exceeding 20% should be stepped uphill with benches 10' or greater in width. Scarify area to receive fill to 6" depth and compact. FILL MA TERI.AL shall not contain insufficient fines, oversized particles, or excessive organics. On-site disposition of oversized rock or expansive soils is to be at the written direction of the Engineer. Select fill shall be as specified by the engineer. All fills shall be compacted and tested. SUBDRAINS shall be installed if required by and as directed by and detailed by the engineer and shall be left operable and unobstructed. They shall consist of 3" plastic perforated pipe set in a minimum cover of 4" of filter rock in a 'vee' ditch to intercept and drain free ground from the mass fills. Perforated pip shall be schedule 40, Poly-Vinyl-Chloride or Acrylonitrile Butadienne Styrene plastic. Rock filter material shall conform to the following gradation: Sieve size: %Passing: 3/4" 90-100 #4 25-50 #30 5-20 #200 0-7 Subdrains shall be set at a minimum gradient of 0.2% to drain by gravity and shall be tested by dye flushing before acceptance. Drains found inoperable shall be excavated and replaced. CAPPING EXPANSIVE SOILS: If capping expansive soils with non-expansive soil to mitigate the expansive potential is used, the cap should be compacted, non-expansive, select soil placed for a minimum thickness 3' over the expansive soil and for a minimum distance of 8' beyond the exterior perimeter of the structure. Special precautions should be taken to ensure that the non-expansive soil remains uncontaminated and the minimum thickness and dimensions around the structure are maintained. The expansive soils underlying the cap of non-expansive cap should be pre-saturated to a depth of 3' to obtain a degree saturation exceeding 90% before any construction supported by the compacted cap. The non-expansive soil comprising the cap should conform to the following: Minimum Compaction Maximum Expansion Index 7 90% 30 Hamro Construction File No. 110614-22 Minimum Angle of Internal Friction Cohesion Intercept 33 Deg 100 psf January 9, 2023 UNFORESEEN CONDITIONS: Soil Testers assume no responsibility for conditions, which differ from those, described in the applicable current reports and documents for this property. Upon termination of the engineer's services for any reason, his fees up to the time of termination become due and payable. If it is necessary for the engineer to issue an unfavorable report concerning the work that he has been hired to test and inspect, the engineer shall not be held liable for any damages that might result from his 'unfavorable report'.
