Prepared by Design Decisions. PDF dated June 3, 2025. • Foundation Plans-Nichols Residence, 1274 Chestnut Avenue, Carlsbad. Prepared by Qualls Engineering. Plan Check Submittal PDF dated June 11, 2025. Site Review: The developed property includes a single-story, single-family residence with a detached 512-sf garage, and two storage sheds. The site's overall topography as well as the proposed ADU area are relatively flat. Project Description: The project will include construction of a new 630-sf, single-story, detached, Accessory Dwelling Unit (ADU) to be located near the northeast corner of the subject property (Figure 1). An existing shed will be removed and replaced with the ADU and associated parking. Foundations will include a shallow, continuous, 12" wide by 12" deep, reinforced concrete perimeter footing, and a 4" thick reinforced slab-on-grade, with a 10-mil vapor barrier centered between 2"/2" of clean sand. Earthwork will include excavation for the new foundation, as well as shallow removal and replacement of any disturbed soils. Geology and Geotechnical Considerations: The site area is located near the western margin of the coastal terrain and mapped as by Old paralic deposits, Units 2 through 4, composed of reddish-brown, strandline, beach, estuarine, and colluvial deposits, composed of siltstone, sandstone, and conglomerate (Kennedy and Tan, 2007, Figure 2).

The Paralic soils are expected to exhibit very low to low expansion potential and are considered non-corrosive. During our site visit we did not note any obvious signs of geologic hazards, groundwater, or other geomorphic or soil related features causing distress to the property. The groundwater table is expected to be below a depth that will influence any planned improvements. The site is not located within any designated geologic hazard zones, including fault rupture, landslide, liquefaction, or tsunami hazard areas. The primary geotechnical consideration for development is the potential for strong ground shaking resulting from regional seismic activity. The nearest active fault is the Newport-Inglewood-Rose Canyon Fault Zone (Oceanside section), located approximately 5.2 miles southwest of the site. Plan Review: SGS! reviewed the referenced foundation plans for consistency with the site's geotechnical conditions. As noted in Foundation Notes 2 and 3 on Sheet Sl.0, and Detail 3 on Sheet SD-1, the following parameters were used in the foundation design: Footini:s Bearing = 1500 psf Width= Min 12" Embedment = Min 12" Seismic design parameters, as noted on plan Sheet SN1 Design Criteria, Seismic Design, include the following: SEISMIC DESIGN CATEGORY D SITE CLASS: D SEISMIC GROUND MOTION VALUES MAPPED ACCELERATION PARAMETERS: SITE COEFFICIENTS DESIGN SPECTRAL ACCELERATION PARAMETERS Ss = 1 050. S1 = 0 381 F1 = 1 200 F = Sos = 0 840. Sot = Conclusions and Recommendations: Based on our assessment, the soil design parameters and seismic design values incorporated into the foundation design appropriate for the site's conditions and underlying soils. Construction of the proposed improvements is considered feasible from a geotechnical standpoint, provided that the recommendations presented below are properly implemented during construction. • Although we do not anticipate significant issues with expansive or corrosive soils based on current information, we recommend testing the subgrade soils at the start 1274 Chestnut Ave ADU ( 1274 Chestnut Ave. ADU Project Number 3.32207 July 7, 2025 of foundation excavation. Should the testing reveal expansive and/or corrosive characteristics, appropriate mitigation measures will be provided. • The project area is expected to be underlain by minor surficial soils, possible disturbed soils once the shed et al. is removed, and granular Old Paralic deposits. Surficial and disturbed soils are not considered suitable for support of foundations or additional fill and should be removed and replaced with compacted fill within all structural areas. • All footing excavations should be observed by the geotechnical consultant prior to placement of reinforcing steel, to verify proper embedment into suitable soils. • Footings shall be moisture conditioned and compacted to at least 90-percent of the maximum dry density obtained using ASTM D1557 as a guideline. • General earthwork and grading recommendations which include guidelines for site preparation fill compaction, slope work, temporary excavations, and trench backfill are provided in the attached Appendix.

GENERAL EARTHWORK AND GRADING General These general earthwork and grading specifications are for the grading and ear thwork shown on the approved grading or construction plan(s) and/or indicated in the geotechnical report(s). These Specifications shall be used in conjunction with the Geotechnical Report for the project prepared by SGS!. In the case of conflict, the recommendations contained in the text of the Geotechnical Report are a part of the earthwork and grading specifications and shall supersede the provisions contained hereinafter. Earthwork and grading should be conducted in accordance with applicable grading ordinances, the current California Building Code, and the recommendations of this report. The following recommendations are provided regarding specific aspects of the proposed earthwork construction. These recommendations should be considered subject to revision based on field conditions observed by the geotechnical consultant during grading, Geotechnical Consultant of Record Prior to commencement of work, the owner shall employ the Geotechnical Consultant of Record. The Geotechnical Consultant shall be responsible for reviewing the approved geotechnical report(s) and accepting the adequacy of the preliminary geotechnical findings, conclusions, and recommendations prior to the commencement of grading or construction, During grading and earthwork operations, the Geotechnical Consultant shall observe, map, and document the subsurface exposures to verify the geotechnical design assumptions. If the observed conditions are found to be significantly different than the interpreted assumptions during the design phase, the Geotechnical Consultant shall inform the owner, recommend appropriate changes in design to accommodate the observed conditions, and notify the review agency where required. Subsurface areas to be geotechnically observed, mapped, elevations recorded, and/or tested include natural ground, after it has been cleared for receiving fill but before it has been placed, bottoms of all "remedial removal areas, all key bottoms, and benches made on sloping ground to receive fill. The Geotechnical Consultant shall observe the moisture-conditioning and processing of the subgrade and fill materials and perform relative compaction testing of fill to determine the attained level of compaction. The Geotechnical Consultant shall provide the test results to the owner and the contractor on a routine and frequent basis. The Earthwork Contractor The Earthwork Contractor shall be solely responsible for performing the grading in accordance with the plans a nd specifications. The Earthwork Contractor shall review and accept the plans, geotechnical report(s), and these Specifications prior to the commencement of grading. The Earthwork Contractor shall have the sole responsibility to provide adequate equipment and methods to accomplish the earthwork in accordance with applicable grading codes and agency ordinances, these Specifications, and the recommendations in the approved geotechnical report(s) and grading plan(s). If, in the opinion of the Geotechnical Consultant unsatisfactory conditions, such as unstable soil, improper moisture condition, inadequate compaction, adverse weather, etc. are resulting in a quality of work less than required in these Specifications, the .INC. Geotechnical Consultant shall reject the work and may recommend to the owner that construction be stopped until the conditions are rectified. Site Preparation Clearing and Grubbing: Site preparation includes removal of deleterious materials, unsuitable materials, and existing improvements from areas where new improvements or new fills are planned. Deleterious materials, which include vegetation, trash, and debris, should be removed from the site, and legally disposed of off-site. Unsuitable materials include loose or disturbed soils, undocumented fills, contaminated soils, or other unsuitable materials. The Geotechnical Consultant shall evaluate the extent of these removals depending on specific site conditions. Earth fill material shall not contain more than 1 percent of organic materials (by volume). No fill lift shall contain more than 5 percent of organic matter. Nesting of the organic materials shall not be allowed. If potentially hazardous materials are encountered, the contractor shall stop work in the affected area, and a hazardous material specialist shall be informed immediately for proper evaluation and handling of these materials prior to continuing to work in that area. As presently defined by the State of California, most refined petroleum products (gasoline, diesel fuel, motor oil, grease, coolant etc. have chemical constituents that are hazardous waste. As such, the indiscriminate dumping or spillage of these fluids onto the ground may constitute a misdemeanor, punishable by fine and/or imprisonment and shall not be allowed. Any existing subsurface utilities that are to be abandoned should be removed and the trenches backfilled and compacted. If necessary, abandoned pipelines may be filled with grout or slurry cement as recommended by, and under the observation of, the Geotechnical Consultant. Excavation After clearing and grubbing of organic matter and other unsuitable material, loose or porous soils shall be removed to the depth recommended in the Geotechnical Report. The depth of removal and compaction should be observed and approved by a representative of the Consultant. The exposed surface shall then be plowed or scarified to a minimum depth of 6 inches and until the surface is free from uneven features that would tend to prevent uniform compaction by the equipment to be used. Remedial removal depths are estimates only. The actual extent of removal shall be determined by the Geotechnical Consultant based on the field evaluation of exposed conditions during grading. All areas to receive fill, including removal and processed areas, key bottoms, and benches, shall be observed, mapped, elevations recorded, and/or tested prior to being accepted by the Geotechnical Consultant as suitable to receive fill. The Contractor shall obtain a written acceptance from the Geotechnical Consultant prior to fill placement. A licensed surveyor shall provide the survey control for determining elevations of processed areas, keys, and benches. Slopes Where the slope ratio of the original ground is steeper than 5:1 (horizontal:vertical), or where recommended by the Consultant, the original ground should be benched in accordance with the following illustration: TYPICAL BENCHING DETAIL Finish Grade Remove All Unsuitable Matenal As Recommended By Consultant Slope To Be Such That Sloughing Or Sliding Does Not Occur On91nal Ground / F1rnsh Slope Surface See Nole 2 No Scale 1) Key width "B" should be a minimum of 4-feet. The bottom of the key should be graded horizontal or inclined slightly into the natural slope. 2) The outside of the key should be below a minimum of at least 2-feet deep into dense formational material. 3) Bench heights shall not exceed 2-foot vertical. Fill placed on ground sloping flatter than 5:1 shall also be benched or otherwise overexcavated to provide a flat subgrade for the fill. Compaction of slopes shall be accomplished by backrolling of slopes with sheepsfoot rollers at increments of 3 to 4 feet in fill elevation, or by other methods producing satisfactory results acceptable to the Geotechnical Consultant. Upon completion of grading, relative compaction of the fill, out to the slope face, shall be at least 90 percent of maximum density per ASTM Test Method D1557. Cut and fill slopes shall be a maximum of 2:1 (horizontal to vertical) unless approved by the Geotechnical Consultant. Planting and irrigation of cut and fill slopes and/or installation of erosion control and drainage devices should be completed due to the erosion potential of the soil. Fill Material Material to be used as fill shall be essentially free of organic matter and other deleterious substances evaluated and accepted by the Geotechnical Consultant prior to placement. Soils of poor quality, such as those with unacceptable gradation, high expansion potential, or low strength shall be placed in a reas acceptable to the Geotechnical Consultant or mixed with other soils to achieve satisfactory fill material. Any import soils shall be tested fo r suitability in advance by the project Geotechnical Engineer. Oversize rock material, or other irreducible material with a maximum dimension greater than 8 inches, shall not be buried or placed in fill unless location, materials, and placement methods are specifically accepted by the Geotechnical Consultant. Placement operations shall be such that nesting of oversized material does not occur and such that oversize material is completely .INC. surrounded by compacted or densified fill. Oversize material shall not be placed within 10 vertical feet of finish grade or within 2 feet of future utilities or underground construction. Compaction All fill and backfill associated with the proposed construction should be placed at a minimum relative compaction of 90% of the material's maximum dry density, and slightly above optimum moisture content, using equipment capable of producing a uniformly compacted product throughout the entire fill lift. Fill materials below optimum moisture content should be moistened and mixed to achieve a uniform condition above optimum moisture. Overly wet fill materials can be aerated by blading or other suitable methods or mixed with drier materials to reach the required moisture content. The fill and backfill should be placed in horizontal lifts with a loose thickness not exceeding 8 inches, appropriate for spreading, mixing, and compacting with the available equipment. Retaining wall backfill should consist of granular material (maximum particle size :5 3 inches) with an expansion index (EI) of no greater than 50 and a sand equivalent (SE) greater than 30. No fill materials shall be placed during unfavorable weather conditions. If work is interrupted by inclimate, fill operations should not resume until the Geotechnical engineer confirms through field testing that the moisture content and density of the fill comply with the specified requirements. Adherence to these procedures will ensure proper compaction and long-term stability of the fill. Compaction Testing Field-tests for moisture content and relative compaction of the fill soils shall be performed by the Geotechnical Consultant. Location and frequency of tests shall be at the Consultant's discretion based on field conditions encountered. Compaction test locations will not necessarily be selected on a random basis. Test locations shall be selected to verify adequacy of compaction levels in areas that are judged to be prone to inadequate compaction (such as close to slope faces and at the fill/bedrock benches). Tests shall be taken at intervals not exceeding 2 feet in vertical rise and/or 1,000 cubic yards of compacted fill soils embankment. In addition, as a guideline, at least one test shall be taken on slope faces for each 5,000 square feet of slope face and/or each 10 feet of vertical height of slope. The Contractor shall assure that fill construction is such that the testing schedule can be accomplished by the Geotechnical Consultant. The Contractor shall stop or slow down the earthwork construction if these minimum standards are not met. Temporary Excavations Temporary excavation shall be made no steeper than 1:1 (horizontal to vertical). The recommended slope for temporary excavations does not preclude local raveling and sloughing. Where wet soils are exposed, flatter excavation of slopes and dewatering may be necessary. In areas of insufficient space for slope cuts, or where soils with little or no binder are encountered, shoring shall be used. All large rocks exposed above temporary cuts shall be removed prior to foundation excavation. In addition, any rocks exposed during development from raveling and sloughing should be removed immediately. ',INC. All excavations should comply with the requirements of the California Construction and General Industry Safety Orders and the Occupational Safety and Health Act and other public agencies having jurisdiction. Trench Backfill Exterior trenches, paralleling a footing and extending below a 1:1 plane projected from the outside bottom edge of the footing, s hall be compacted to a minimum of 95-percent per ASTM D1557. All trenches in structural areas and under concrete flatwork shall be compacted to a minimum of 95-percent per ASTM D1557. All trenches in non-structural areas shall be compacted to a minimum of 85-percent per ASTM D1557. All material used for trench backfill shall be approved by the Geotechnical Engineer prior to placement. All bedding and backfill of utility trenches shall be done in accordance with the applicable provisions of Standard Specifications of Public Works Construction. Bedding material shall have a Sand Equivalent greater than 30 (SE>30). The bedding shall be placed to 1-foot over the top of the conduit and densified by jetting. Backfill shall be placed and densified to a minimum of 95-percent of maximum from 1-foot above the top of the conduit to the surface. Lift thickness of trench backfill shall not exceed those allowed in the Standard Specifications of Public Works Construction unless the Contractor can demonstrate to the Geotechnical Consultant that the fill lift can be compacted to the minimum relative compaction by his alternative equipment and method. The Geotechnical Consultant shall test the trench backfill for relative compaction. At least one test should be made for every 300 feet of trench and 2 feet of fill. Regulations of the governing agency may supersede the above, and all trench excavations should conform to all applicable safety codes.

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. A completed and signed questionnaire must be submitted with each development project application.
