M Y BUILDING PLANCHECK CHECKLIST WATER METER REVIEW ..ST 2ND 3RD D D D 12a. Domestic (potable) Use Ensure that the meter proposed by the owner/developer is not oversized. Oversized meters are inaccurate during low-flow conditions. If it is oversized, for the life of the meter, the City will not accurately bill the owner for the water used. • All single family dwelling units received "standard" 1" service with 5/8" service. • owner/developer proposes a size other than the "standard", then owner/developer must provide potable water demand calculations, which include total fixture counts and maximum water demand in gallons per minute (gpm). A typical fixture count and water demand worksheet is attached. Once the gpm is provided, check against the "meter sizing schedule" to verify the anticipated meter size for the unit. • Maximum service and meter size is a 2" service with a 2" meter. D D D 12b. Irrigation Use (where recycled water is not available) All irrigation meters must be sized via irrigation calculations (in gpm) prior to approval. The developer must provide these calculations. Please follow these guidelines: If the project is a newer development (newer than 1998), check the recent improvement plans and observe if the new irrigation service is reflected on the improvement sheets. If so, at the water meter station, the demand in gpm may be listed there. Irrigation services are listed with a circled "I", and potable water is typically a circled "W". 1. If the improvement plans do not list the irrigation meter and the service/meter will be installed via another instrument such as the building plans or grading plans (w/ a right of way permit of course), then the applicant must provide irrigation calculations for estimated worst-case irrigation demand (largest zone with the farthest reach). Typically the Planning Dept. Landscape Consultant has already reviewed this if landscape plans have been prepared, but the applicant must provide the calculations to you for your use. Once you have received a good example of irrigation calculations, keep a set for your reference. In general the calculations will include: Hydraulic grade line Elevation at point of connection (POC) Pressure at POC in pounds per square inch (PSI) Worse case zone (largest, farthest away from valve Total Sprinkler heads listed (with gpm use per head) Include a 10% residual pressure at point of connection BUILDING PLANCHECK CHECKLIST ..ST 2ND 3RD d CH CH 12c. Irrigation Use (where recycled water is available) 1. Recycled water meters are sized the same as the irrigation meter above. 2. If a project fronts a street with recycled water, then they should be connecting to this line to irrigate slopes within the development. For subdivisions, this should have been identified, and implemented on the improvement plans. Installing recycled water meters is a benefit for the applicant since they are exempt from paying the San Diego County Water Capacity fees. However, if they front a street which the recycled water is there, but is not live (sometimes they are charged with potable water until recycled water is available), then the applicant must pay the San Diego Water Capacity Charge. If within three years, the recycled water line is charged with recycled water by CMWD, then the applicant can apply for a refund to the San Diego County Water Authority (SDCWA) for a refund. However, let the applicant know that we cannot guarantee the refund, and they must deal with the SDCWA for this. D D D 13.

The results of tie questionnaire determine the level of storm water pollution prevention standards applied to a proposed development or redevelopment project Many aspects of project site design are dependent upon the storm water pollution protection standards applied to a project. Applicant 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 applicator). A staff determination that the development application is subject to more stringent storm water standards, than initially assessed by the applicant, will result in the return of the development application as incomplete. If applicants are unsure about the meaning of a question or need help in determining how to respond to one or more of the questions, they are advised to seek assistance from Engineering Department Development Services staff. A separate completed and signed questionnaire roust b& submitted for each new development application submission. Only one completed and signed questionnaire is required when multiple development applications for the same project are submitted concurrently. In addition to this questionnaire, applicants for construction permits must also complete, sign and submit a Construction Activity Storm Water Standards Questionnaire. To address pollutants that may be generated from new development, the City requires that new development and significant redevelopment priority projects incorporate Permanent Storm Water Best Management Practices (BMPs) into the project design, which are described in Chapter 2 of the City's Storm Water Standards Manual This questionnaire should be used to categorize new development and significant redevelopment projects as priority or non-priority, to determine what level of storm water standards are required or if the project is exempt f 1 Is your project a svsniflcant redevelopment? I Definition: S/gnfficant redevelopment is defined as the creation, addition or replacement of at least 5,000 square feet of impwvious surface on an atmady existing developed site. Significant redevelopment includes, but Is not fimited to: the expansion of a building footprint; addition to or replacement of a structure; structural development including an increase in gross floor area and/or exterior construction remodeling; replacement of an impervious surface that is nor part of a routine maintenance activity; and tend disturbing activities related Matt) structured or impervious surfaces. Replacement of impervious surfaces includes any activity that is not part of a routine maintenance activity where impervious material® are removed, exposing underlying soil during construction. Note: If the Significant Redevelopment results in an increase of less than fifty percent of the impervious surfaces of a previously existing development, and the existing development was not subject to SUSMP requirements, the numeric sizing criteria discussed in Table 3 of 2.3.3.4 applies only to the addition, and not to the entire development 2.

Our investigation has found that the area of the proposed residence is underlain by topsoil to a depth of approximately 2 feet below existing grade. Dense sandstone of the Terrace Deposits Formation was underlying the topsoil to the explored depth of 10 feet. It is our opinion that the construction of the proposed single-family residence is geotechnically feasible provided the recommendations herein are implemented in the design and construction. Should you have any questions regarding the contents of this report, please do not hesitate to contact our office. Respectfully submitted, M Mamadou Saliou Diallo, P.E.

The objectives of the investigation were to evaluate the existing soils conditions and provide recommendations for the proposed construction. SCOPE OF SERVICES The following services were provided during this investigation: • Site reconnaissance and review of published geologic, seismological and geotechnical reports and maps pertinent to the project area • Subsurface exploration consisting of four (4) boreholes within the limits of the proposed area of development. The boreholes were logged by our Staff Geologist. • Collection of representative soil samples at selected depths. The obtained samples were sealed in moisture-resistant containers and transported to the laboratory for subsequent analysis. • Laboratory testing of samples representative of the types of soils encountered during the field investigation • Geologic and engineering analysis of the field and laboratory data, which provided the basis for our conclusions and recommendations • Production of this report, which summarizes the results of the above analysis and presents our findings and recommendations for proposed residence. SITE DESCRIPTION AND PROPOSED CONSTRUCTION The subject site is a residential lot located on the north side of Chestnut Avenue, in the City of Carlsbad, California. The property is vacant and encompasses an area of approximately 10,700 square feet. It slopes gently to the west. Vegetation consisted of grass. The parcel is bordered by Chestnut Avenue to the south, a vacant lot to the west and similar residential developments to the remaining directions. A private driveway will access the properly from Adams Street. No architectural drawings were available at the time of this investigation. It is our understanding that the proposed construction will include a single-family residence. The structure will be one- story, wood-framed and founded on continuous footings with a raised-wood floor. DAVETROTTA, CHESTNUT AVENUE, CARLSBAD PROJECT NO. 09-1106F5 FIELD INVESTIGATION AND LABORATORY TESTING On December 15, 2009, four (4) boreholes were drilled to a maximum depth of approximately 10.0 feet below existing grade with a hand auger. The approximate locations of the boreholes are shown on the attached Plate No. 1, entitled "Location of Exploratory Boreholes". A continuous log of the soils encountered was recorded at the time of drilling and is shown on Plate No. 2 entitled "Summary Sheet". The soils were visually and texturally classified according to the filed identification procedures set forth on the attached Plate No. 3 entitled "USCS Soil Classification". Following the field exploration, laboratory testing was performed to evaluate the pertinent engineering properties of the foundation materials. The laboratory-testing program included moisture and density, maximum dry density and optimum moisture content, particle size analysis and expansion index tests. These tests were performed in general accordance with ASTM standards and other accepted test methods. Page L-l and Plate No. 2 provide a summary of the laboratory test results. GEOLOGY Geologic Setting The subject site is located within the southern portion of what is known as the Peninsular Ranges Geomorphic Province of California. The geologic map pertaining to the area indicates that the site is underlain by Pleistocene marine terrace deposits (Qt). Site Stratigraphy The subsurface descriptions provided are interpreted from conditions exposed during the field investigation and/or inferred from the geologic literature. As such, all of the subsurface conditions may or may not be represented. Detailed descriptions of the subsurface materials encountered during the field investigation are presented on the exploration logs provided on Plate No. 2. The following paragraphs provide general descriptions of the encountered soil types. Topsoil Topsoil is the surficial soil material that mantles the ground, usually containing roots and other organic materials, which supports vegetation. Topsoil observed in the boreholes was approximately 2-foot thick and consisted of dark brown, silty sand that was moist, loose and porous in consistency with minor amounts of organics (roots and rootlets). Marine Terrace Deposits ( Qt) Terrace deposits were observed below the topsoil layer. They generally consisted of reddish brown, silty sand that was dry to moist and medium dense to dense in consistency. DAVETROTTA, CHESTNUT AVENUE, CARLSBAD PROJECT NO. 09-1106F5 SEISMICITY Regional Seismicity Generally, Seismicity within California can be attributed to the regional tectonic movement taking place along the San Andreas Fault Zone, which includes the San Andreas Fault and most parallel and subparallel faults within the state. The portion of southern California where the subject site is located is considered seismically active. Seismic hazards are attributed to groundshaking from earthquake events along nearby or more distant Quaternary faults. The primary factors in evaluating the effect an earthquake has on a site are the magnitude of the event, the distance from the epicenter to the site and the near surface soil profile. According to the Fault-Rupture Hazard Zones Act of 1994 (revised Alquist-Priolo Special Studies Zones Act), quaternary faults have been classified as "active" faults, which show apparent surface rupture during the last 11,000 years (i.e., Holocene time). "Potentially-active" faults are those faults with evidence of displacing Quaternary sediments between 11,000 to 16,000 years old. Seismic Analysis Base on our evaluation, the closest known "active" fault is the offshore trace of the Rose Canyon Fault located approximately 5 miles (8 kilometers) to the west. The Rose Canyon Fault is the design fault of the project due to the predicted credible fault magnitude and ground acceleration. The Seismicity of the site was evaluated utilizing deterministic methods (Eqseach ver 3.0, Blake, 2000) for active Quaternary faults within the regional vicinity. The site is subject to a Maximum Probable Earthquake of 6.9 Magnitude along the Rose Canyon fault, with a corresponding Peak Ground Acceleration of 0.43g. The maximum Probable Earthquake is defined as the maximum earthquake that is considered likely to occur within a 100-year time period. The effective ground acceleration at the site is associated with the part of significant ground motion, which contains repetitive strong-energy shaking, and which may produce structural deformation. As such, the effective or "free field" ground acceleration is referred to as the Repeatable High Ground Acceleration (RHGA). It has been determined by Ploessel and Slosson (1974) that the RHGA is approximately equal to 65 percent of the Peak Ground Acceleration for earthquakes occurring within 20 miles of a site. Based on the above, the calculated Credible RHGA at the site is 0.28g. 2007 CBC Seismic Design Criteria A review of the active fault maps pertaining to the site indicates the existence of the Rose Canyon Fault Zone approximately 8 km to the west. Ground shaking from this fault or one of the major active faults in the region is the most likely happening to affect the site. With respect to this hazard, the site is comparable to others in the general area. The proposed structure should be designed in accordance with seismic design requirements of the 2007 California Building Code or the Structural Engineers Association of California using the following seismic design parameters: DAVE TROTTA, CHESTNUT AVENUE, CARLSBAD PROJECT NO. 09-1106F5 rPAItilVIETER Site Class Mapped Spectral Acceleration For Short Periods, Ss Mapped Spectral Acceleration For a 1 -Second Period, Si Site Coefficient, Fa Site Coefficient, Fv VALUE D 1.25 0.50 1.0 1.5 2007 CBC REFERENCE Table 1613.5.2 Figure 1613.5(3) Figure 1613.5(4) Table 1613.5.3(1) Table 1613.5.3(2) Geologic Hazard Assessment Ground Rupture Ground rupture due to active faulting is not considered likely due to the absence of known fault traces within the vicinity of the project, however, this possibility cannot be completely ruled out. The unlikely hazard of ground rupture should not preclude consideration of "flexible" design for on-site utility lines and connections. Liquefaction Liquefaction involves the substantial loss of shear strength in saturated soils, usually sandy soils with a loose consistency when subjected to earthquake shaking. Based on the absence of shallow groundwater and consistency of the underlying terrace deposits, it is our opinion that the potential for liquefaction is very low. Landsliding There is no indication that landslides or unstable slope conditions exist on or adjacent to the project site. There are no obvious geologic hazards related to landsliding to the proposed development or adjacent properties. Tsunamis and Seiches Since the subject property is approximately 100 feet above mean sea level, it is unlikely that an earthquake-generated tsunami would affect the site. According to the CSG' website, the largest recorded tsunami to hit the San Diego area was 3.6 meters (approximately 12 feet) in the year 1856, from a seismic event in Japan. The site is also not subject to seiches (waves in confined bodies of water). GEOTECHNICAL EVALUATION Based on our field investigation and evaluation of the collected information, we conclude that the proposed single-family residence is feasible from a geotechnical standpoint provided the recommendations herein will be properly implemented during construction. In order to provide a uniform support for the proposed structure, the proposed footings should be extended to the dense terrace deposits unless overexcavation and recompaction of the structural DA VE TROTTA, CHESTNUT A VENUE, CARLSBAD PROJECT NO. 09-1106F5 portion of the building pad is performed. The foundation may consist of reinforced continuous footings with conventional reinforced slabs. Recommendations and criteria for foundation design are provided in the Foundation and Slab recommendations section of this report. Compressible Soils Our field observations and testing indicate low compressibility within the terrace deposits, which underly the area of the proposed building. However, loose topsoil was typically encountered to a depth of approximately 2 feet below surface grades. These soils are compressible. Due to the potential for soil compression upon loading, recompaction of these soils will be required unless footings are extended to the dense sandstone of the Terrace Deposits Formation. Following implementation of the earthwork recommendations presented herein, the potential for soil compression resulting from the new development has been estimated to be low. The low-settlement assessment assumes a well-planned and maintained site drainage system. Recommendations regarding mitigation by earthwork construction are presented in the Grading and Earthwork recommendations section of this report. Expansive Soils An expansion index test was performed on a representative sample of the terrace deposits to determine volumetric change characteristics with change in moisture content. An expansion index of 0 was obtained which indicates a very low expansion potential for the foundation soils. Groundwater Static groundwater was not encountered to the depths of the boreholes. The building pad is located at an elevation of approximately 100 feet above Mean Sea Level. We do not expect groundwater to affect the proposed construction. Recommendations to prevent or mitigate the effects of poor surface drainage are presented in the Drainage section of this report. CONCLUSIONS AND RECOMMENDATIONS The following conclusions and recommendations are based upon the analysis of the data and information obtained from our soil investigation. This includes site reconnaissance; field investigation; laboratory testing and our general knowledge of the soils native to the site. The site is suitable for the proposed residential development provided the recommendations set forth are implemented during construction. EARTHWORK The following earthwork recommendations are based upon the limited geotechnical investigation performed, and should be verified during construction by our field representative. DAVETROTTA, CHESTNUT AVENUE, CARLSBAD PROJECT NO. 09-1106F5 Clearing and Grubbing Site preparation should consist primarily of clearing and grubbing, i.e. the removal of vegetation and deleterious materials. Vegetation and the debris from the clearing operation should be properly disposed of off-site. The area should be thoroughly inspected for any possible buried objects, which need to be rerouted or removed prior to the inception of, or during grading. All holes, trenches, or pockets left by the removal of these objects should be properly backfilled with compacted fill materials. Based on our field investigation, dense sandstone of the Terrace Deposits Formation is underlying the proposed area of development at shallow depths. It is our opinion that these soils will be adequate for the support of the proposed structure without detrimental settlement. However, for the garage slab support, we recommend overexcavation and recompaction of the upper two feet of surface soils. Foundation excavations should be observed by a representative of this firm to verify competent bearing soils. Erosion Control Due to the granular characteristics of the subgrade soils, areas of exposed ground may be subject to erosion. During construction, surface water should be controlled via berms, sand/ gravel bags, silt fences, straw wattles, siltation basins, positive surface grades or other method to avoid damage to the finish work or adjoining properties. All site entrances and exits must have coarse gravel or steel shaker plates to minimize offsite sediment tracking. Best Management Practices (BMPs) 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 site preparation, all excavated surfaces should exhibit positive drainage and eliminate areas where water might pond. FOUNDATIONS AND SLABS a. Continuous and spread footings are suitable for use and should be embedded a minimum of 12 inches below the lowest adjacent grade for the one-story, single-family residence into the dense sandstone of the Terrace Deposits Formation. Continuous footings should be at least 12 inches in width and reinforced with four #4 steel bars; two bars placed near the top of the footings and the other two bars placed near the bottom of the footings. b. The concrete garage floor slab should be a minimum 4-inch thick. Reinforcement should consist of #3 bars placed at 18 inches on center each way within the middle third of the slab by supporting the steel on chairs or concrete blocks "dobies". The slab should be underlain by 2 inches of clean sand over a 10-mil visqueen moisture barrier. The effect of concrete shrinkage will result in cracks in virtually all concrete slabs. To reduce the extent of shrinkage, the concrete should be placed at a maximum of 4-inch slump. The minimum steel recommended is not intended to prevent shrinkage cracks. Reinforcement for actual loading conditions should be as required by the structural engineer. c. An allowable soil bearing value of 2,000 pounds per square foot may be used for the design of continuous and spread footings at least 12 inches wide and founded a minimum of 12 inches into the dense sandstone of the Terrace Deposits Formation as set forth in the 2007 California Building DAVETROTTA, CHESTNUT AVENUE, CARLSBAD PROJECT NO. 09-1106F5 Code, Table 1804.2. This value may be increased by 400 psf for each additional foot of depth or width to a maximum value of 4,000 Ib/ft2. d. 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 as well as the bearing value may be increased by 1/3 for wind and seismic loading. SETTLEMENT Settlement of compacted fill is normal and should be anticipated. Since the proposed footings are anticipated to be supported by the dense sandstone of the Terrace Deposits Formation, the total and differential settlement should be within tolerable limits. PRESATURATION OF SLAB SUBGRADE Because of the granular characteristics of the existing soils, presoaking of the subgrade prior to concrete pour is not required. However, subgrade soils in areas receiving concrete should be watered prior to concrete placement to mitigate any drying shrinkage, which may occur following site preparation. TEMPORARY SLOPES Excavations for foundations or on-site utility trenches may be made vertically for shallow depths and must be either shored or sloped at 1H: IV for depths greater than 4 feet; OSHA guidelines for trench excavation safety should be observed during construction. TRENCH BACKFILL Excavations for utility lines, which extend under structural areas should be properly backfilled and compacted. Utilities should be bedded and backfilled with clean sand or approved granular soil to a depth of at least one foot over the pipe. This backfill should be uniformly watered and compacted to a firm condition for pipe support. The remainder of the backfill should be on-site soils or non- expansive imported soils, which should be placed in thin lifts, moisture-conditioned and compacted to at least 90% relative compaction. DRAINAGE Adequate measures should be undertaken to properly finish grade the site after the structure and other improvements are in place, such that the drainage water within the site and adjacent properties is directed away from the foundations, footings, floor slabs and the tops of slopes via rain gutters, downspouts, surface swales and subsurface drains towards the natural drainage for this area. A minimum gradient of 1 percent is recommended in hardscape areas. For earth areas, a minimum gradient of 5 percent away from the structure for a distance of at least 5 feet should be provided. Earth swales should have a minimum gradient of 2 percent. Drainage should be directed to approved drainage facilities. Proper surface and subsurface drainage will be required to DAVETROTTA, CHESTNUT AVENUE, CARLSBAD PROJECT NO. 09-U06F5 minimize the potential of water seeking the level of the bearing soils under the foundations, footings and floor slabs, which may otherwise result in undermining and differential settlement of the structure and other improvements. FOUNDATION EXCAVATION OBSERVATION During construction, foundation excavations should be observed by our representative prior to the placement of forms, reinforcement or concrete for conformance with the plans and specifications.

Dear Mr. Trotta: This report presents the results of field density tests performed on the garage slab areas for the proposed single-family residence at the subject site. In accordance with your request, in-place field density tests were performed in accordance with ASTM D1556 (Sand Cone Method). The results of the field density tests are presented on Page T-l under "Table of Test Results". The laboratory determinations of the maximum dry density and optimum moisture content of the fill soils are set forth on Page L-l under "Laboratory Test Results". The approximate locations of the field density tests are shown on Plate No. 1. Following clearing and grubbing, i.e. the removal of vegetation and deleterious materials, subgrade soils within the garage slab areas were overexcavated to a depth of approximately 2 feet below proposed finish pad grades. The bottom of the excavation was scarified to a depth of approximately 6 inches, moisture conditioned and compacted. On-site fill soils consisting of silty sand were placed in thin lifts and compacted in excess of 90 percent relative compaction while maintaining a moisture content near optimum. Compaction was achieved with the use of a rubber tired loader. DAVE TROTTA PROJECT NO. 09-1106F5 Based on our field observations and density test results, it is our opinion that the grading operation for the proposed garage slabs was performed in accordance with the referenced geotechnical investigation report (Reference No. 2) and local grading ordinances.
