Carlsbad, CA 92009 HA Project Number 181116 Project Number 18-676 This report summarizes my review of Installation records and photographs of the work performed by Foundations-on-the-Level. This work was performed between 4-29-19 and 5-8-19. Inspection of the work was performed by a Helfrich-Associates Inspector working under my direction. This report responds to the City inspector notice dated 5/8/19 (copy attached). HELICAL PIERS Nine helical piers were Installed below the affected footings of the home. Installed depths of the piers ranged from 9 feet to 13 feet, and final Installation PSI ranged from about 3150 ft-lbs to 5400 ft-lbs. Pier 10 was eliminated from the plan, based on its proximity to Pier 9. A 2x6 steel beam, 10 feet long, was Installed between piers 6 and 7 to support the footing below the door opening. BUILDING LIFT Maximum bulldlng 11ft was about 1 ½ Inches along the front. Interior slabs and footings were then supported with structural grout. CONCLUSIONS The piers were Installed In general accordance with the plans, and the design Intent was achieved. I appreciate the opportunity to assist you in this matter.

Based on our understanding of the project, it appears that the north and west sides of the structure have experienced some movement. A floor level survey performed by others indicates a differential elevation of approximately 2-1/2 inches. Based on our review of the information provided, it is our opinion that soil movement associated with fill settlement and improper drainage are the causes of the observed distress to the foundations of the building. It is our recommendation that stabilization of the structure should be performed by installing helical piers to stabilize the building. Recommendations for stabillzatlon of the structure are provided in the Recommendations section of this report. Site Description The subject site is located at 2077 Caleta Court in the City of Encinitas, California. The property is about 0.5 acre in size and is occupied by a single-family residence that is about 3,168 square feet in size. The pad elevation is about 86 feet above mean sea level. The site is bounded on the northeast by Caleta Court, by residential properties to the northwest and southeast, and by vacant land to the south. The site is situated in northeast quarter of the southeast quarter of Section 26, Range 4 West, Township 12 South, San Bernardino Principal Meridian, at latitude 33.099607 north, longitude 117.263409 west. Laboratory Testing Laboratory testing was performed by Hilltop Geotechnical, Inc. Samples were provided to the laboratory by the client. Expansion index testing was performed on a representative sample to evaluate the expansion potential of the soils. A representative sample was > 1--0 Soils Report 2077 Caleta Court Page No. 2 tested for corrosivity characteristics including sulfates, chlorides, minimum resistivity and pH. Laboratory test results appear in the Appendix. Soil classifications provided in our geotechnical investigation are in general accordance with the Unified Soil Classification System (USCS). Helfrich-Associates has reviewed the laboratory test results and accepts the results for use in our analysis. Geologlc Units The subject site Is underlain by artificial fill soils composed of clayey, fine-to coarse- grained sand (SC), which is light brown in color and moist. Bedrock underlies the fill soils. Bedrock is described as Santiago formation, a well-consolidated sandstone of Eocene age. Groundwater The nearest water well for which information was available through the State of California Department of Water Resources, Water Data Library, was well No. 329812N1172318W001, which located about eight mlles south-southeast of the site. Because of the distance and different geologic conditions, data from this source was not deemed pertinent to this project. Due to the nature of the project, groundwater is not considered to be a constraint for this project. GEOLOGIC HAZARDS Faultlng and Ground Rupture The site does not lie within an Alqulst-Prlolo (AP) Special Studies zone. There is no AP earthquake fault zones map for the Encinitas Quadrangle. As with most of southern California, however, the subject site is situated in an area of active and potentially active faults. Active faults present several potential risks to structures, the most common of which are strong ground shaking, dynamic densification, liquefaction, mass wasting, and surface rupture at the fault plane. The following four factors are the principal determinants of seismic risk at a given location: • Distance to seismogenically capable faults. • The maximum or "characteristic" magnitude earthquake for a capable fault. • Seismic recurrence interval, In turn related to tectonic slip rates. • Nature of earth materials underlying the site. Based upon proximity to regionally significant, active faults, ground shaking is the primary hazard most likely to affect the site. Characteristics of the major active fault zones selected for inclusion in analysis of strong ground shaking are listed in the following table. Numerous significant fault zones are located at distances exceeding 40 kilometers from the site, but greater distances, lower slip rates, and/or lesser maximum magnitudes indicate much lower risk to the site from the latter fault zones than those listed below. 30640 Kristin Court.

There are no State of California or County of San Diego seismic hazards maps for the area of the subject site. Based on a landslide susceptibility map (1995), the subject site lies in an area that Is "generally susceptible" to landslides. However, the area of the site is low relief, and there are no mapped landslides near the subject property. Landslides are not considered to be a constraint at the subject site. Liquefaction There are no liquefaction hazard maps available from the State of California for the subject site. The County of San Diego has a draft liquefaction map (Hazard Mitigation Planning, undated), which places the subject site outside of known or suspected liquefaction zones. Additionally, the subject site is underlain by Santiago Formation bedrock, which is not liquefiable. Liquefaction is not considered to be a constraint at the subject site. Floodlng According to FEMA, the subject site is within flood hazard zone "X" (2009), which is defined as being outside the 500-year flood zone. Flood Ing is not a geologic constraint at this site. 30640 Kristin Court, Redlands, CA 92373 -909-389-7316 -Fax 909-389-7326 -www.helfrlch-assoclates.com Soils Report 2077 Caleta Court Page No. 4 Expansive Solls The results of our expansion index testing indicate that the soils encountered at the site are considered "high" expansive. Recommendations provided in this report are made with consideration to the expansive conditions of the on-site soils. CONCLUSION Our research and field and laboratory investigations confirm that the proposed underpinning project is feasible from a geological and geotechnlcal engineering standpoint, provided the recommendations contained in this report are implemented during design and construction. Due to the "high" expansive nature of the subsurface soils, it is our recommendation to underpin the structure using helical piers to stabilize the building. These piers should be attached to the house to provide uplift resistance. RECOMMENDATIONS Re-Leveling Using Helical Piers The re-leveling/ underpinning of exterior footings can be performed utlllzlng 2-7/8-inch round bar helical anchor piers with helical underpinning brackets installed to a minimum torque of 3000 ft-lbs for an allowable (FS = 2) capacity of 13.5 kips. The actual capacity of the helical piers is determined from published correlations with the Installation torque and should be verified by load testing during installation. The helical piers should consist of 6/8 helices at a minimum installed with a tension connection to transfer upllft forces on the house to the piers. The piers should be installed to a minimum of 15 feet below the bottom of the existing foundations and should be founded in dense materials. Construction and inspection requirements for installation of the helical piers have been placed on the repair plans. The effect of group action will not be significant when the piles are spaced at least 3 times the diameter. Helical piers for this project are not intended to resist seismic, wind, or lateral soil loads. Total and differential settlement of the foundations where the piers have been installed under their design loads is expected to be less than 1/2 and 1/4 inch, respectively. It is our opinion that additional lateral support is not required for this project. Lateral Loading Resistance to lateral loads will be provided by passive earth pressure and cohesion of the existing foundation system. Passive earth pressure will be developed at a rate of 100 psf 30640 Kristin Court, Redlands, CA 92373 -909-389-7316 -Fax 909-389-7326 -www.helfrlch-assoclates.com Soils Report 2077 Caleta Court Page No. 5 per foot of depth. Cohesion may be computed as 130 psf multiplied by the contact area of the footings. Cohesion and passive earth pressure may be combined without reduction. These values are based on Type 5 materials as per table 1806.2 of the California Building Code and should be confirmed with testing during construction. Corrosion Due to the corrosive potential of the onsite soils to ferrous metals, the piers and brackets should be galvanized or designed with adequate sacrlflcial thickness redundancy to provide a minimum 50-year design life. Exterior Repair Recommendations The stabilization should be performed by coordinated raising of the perimeter and interior of the structure. Upon completion of the stabilization operation, it is recommended that the foundation be observed for cracks in the footings and stemwalls. Cracks in the footings and stemwalls greater than 1/8 inch should be structurally evaluated and repaired so that the structural integrity of the footing is maintained. Foundation cracks less than or equal to 1/8-inch-wide should be injection grouted with Simpson ETI-LV or GV epoxy. After the piers are installed and the building is lifted, structural grout should be injected into the space below the foundations and slabs to restore the original soil support to the structure. Addltlonally, the stabilization may cause distress to the utility connections to the building. Care should be taken to protect the connections, and they should be monitored and tested upon completion of the stabilization activities and repaired as necessary. Exterior repairs should be performed after the foundation repairs are made to restore the landscaping, irrigation, and patios/sidewalks to their preconstruction condition. Planters should be provided with area drains to prevent water ponding. Irrigation systems should be carefully installed and monitored to ensure that soils near the building and/or slopes are not over-irrigated. Drainage Surface drainage should be maintained sloping away from the structure to ensure that water does not pond next to the foundations. The site should be graded so that surface water flows away from structures at a minimum gradient of 5 percent for a minimum distance of 10 feet from structures. Impervious surfaces within 10 feet of structures should be sloped a minimum of 2 percent away from the building. Water should not be allowed to flow over graded areas or natural areas. Graded areas should be planted or otherwise protected from erosion by wind or water. Interior Repair Recommendations Additional distress to the building, such as drywall cracking may occur during the stabilization. Therefore, It Is recommended that a qualified contractor who specializes in performing such stabilization performs the repairs. Cosmetic repairs to the building are 30640 Kristin Court, Redlands, CA 92373 -909-389-7316 -Fax 909-389-7326 -www.helfrlch-assoclates.com Soils Report 2077 Caleta Court Page No. 6 likely to consist of repairs to the interior and exterior walls, ceilings, and floor surfaces. This work should be done after the stabilization work is completed. It is recommended that any cracks within the interior floor slab be repaired as detailed below. Slab cracks less than or equal to 1/4-inch-wide should be injection grouted with Simpson ETI-LV or GV epoxy. Slab cracks greater than 1/4-lnch-wide but less than 1/2-inch-wide should be filled with Simpson ETI-LV or GV epoxy and reinforced with Fortress Carbon Fiber Staples at 18 inches on center across the crack. Cracks greater than 1/2 inches or more than 1/8 inches vertical offset should be removed and replaced. The cracked section should be saw-cut and replaced with a new slab doweled into the existing slab. The removed portions of the slab may be replaced with a new slab of the same thickness or thicker. The replacement slab should be reinforced with at least No. 4 steel reinforcing bars placed in both directions at 18 Inches on center. The reinforcement should be placed in the middle one-third of the slab height. It is recommended that "chairs" be utilized to aid in the placement and support of the reinforcement. If a moisture barrier is present, it should be reconstructed. The concrete utilized in the new slab should have a slump of 4 inches or less. Cracks in the concrete can occur due to shrinkage. The above recommendations regarding the reinforcement and concrete design should be taken only as minimal and should be verified by the project Structural Engineer. If ceramic tiles are installed as a future floor covering, it is recommended that the floor tiles be underlain with a slip sheet or other method for reducing the potential for future cracking of the tiles. Any underlayment should be installed in accordance with the recommendations of a qualified tile contractor. Earthwork Earthwork at the site is anticipated to be relatively minor and limited to excavation for the lifting points, minor site grading, and subgrade preparation associated with the floor slab and foundation repair. The on-site soils are considered "high" expansive and should be moisture conditioned to 3 to 5 percent above optimum moisture content when re-using the material as compacted fill. "High" expansive soils are not anticipated to significantly affect the structure when stabilized using helical piers. Excavation difficulties are not anticipated, and conventional grading equipment may be used. Within areas where earthwork is to be performed, any existing ground Improvements, vegetation, or loose debris should be removed to expose the underlying soils. The subgrade should be verified to be firm and unyielding. Compacted fill should be placed in horizontal lifts not more than 8 inches in loose thickness and compacted to at least 90 percent of the maximum dry density, as evaluated by the latest version of ASTM D1557. 30640 Kristin Court, Redlands, CA 92373 -909·389-7316 -Fax 909-389-7326 -www.helfrlch-assoclates.com Soils Report 2077 Caleta Court Page No. 7 The moisture content of the fill during compaction should be brought to 3 to 5 percent above optimum moisture content. The on-site soils, less any contaminated soil, debris, organic matter, or other deleterious materials, may be used in the site fills. Rock or other soil fragments greater than 4 inches in size should not be used in the fills. Temporary, shallow excavations with vertical side slopes will generally be stable, but there Is a potential for minor sloughing. All excavations should be made in accordance with Cal- OSHA requirements. Adlacent Properties Statement Based on our field investigation and laboratory testing results, it is our opinion that the proposed underpinning will be safe against hazards from landslide, settlement or slippage and the proposed construction will have no adverse effect on the geologic stability of the adjacent properties or future developments provided the recommendations presented in this report are followed. Closure The recommended repairs are intended to stabilize the foundations and slabs in the affected parts of the site. Due to the nature of the subsurface conditions at the property, additional future movement of the building and surrounding concrete slabs should be anticipated. Areas of the property that have not been repaired may experience damage in the future, although the extent of this damage is anticipated to be minor, provided good irrigation and maintenance practices are followed as provided In Appendix B.

PLATENO.1. HILLTOP GEOTECHNICAL, INC. APPENDIX B MAINTENANCE RECOMMENDATIONS MAINTENANCE RECOMMENDATIONS The most important aspect of slope maintenance is proper control of surface drainage. Uncontrolled water from broken pipes, improperly maintained irrigation systems, and rainfall are the most prevalent cause of slope Instability in Southern California. The following recommended procedures should be followed by the property owner to minimize slope instability: 1) Homes should be provided with roof drains, gutters, and downspouts, and these facilities should be checked at least twice per year. 2) All drainage devices should be checked at least twice per year to ensure that they are not blocked. All blockages should be cleared. 3) Drains at the top of slopes should not allow water to overflow onto the slope. 4) Terrace drains and brow ditches on slopes or at the tops of slopes are designed to carry runoff water to an appropriate discharge point. These drains should be checked at least twice per year, and cleaned of any accumulation of dirt and other debris. Water that backs up in surface drains will overflow and seep into the slope, creating instability. 5) Water should not be permitted to collect or pond in yard areas. This water will either seep into the ground (loosening the solls) or will overflow onto the slope. Once erosion is started, it is difficult to control and severe damage can occur quickly. 6) Loose soll or debris should not be left on slopes. Loose soils soak up water more readily than compacted fill, and will often slide downslope. This material may clog terrace drains, and may cause additional slope damage. 7) Slopes should not be over-irrigated. Naturally, ground cover will require some moisture during the hot summer months, but during the wet season, irrigation can cause heavy ground cover to move, which not only destroys the cover, but also may begin slope surface erosion. Heavy ground cover can cause surface sloughing when saturated due to the increased weight and weakening of the near surface soil. 8) Water should not be allowed to collect against foundations, retaining walls, or basement walls. These walls are typically built to withstand the effects of normal soil moisture, and may require subsurface drains to collect and transfer excessive water away from the structures. 9) Irrigation systems should not be left running on or near a slope, particularly during the rainy season. 10) Swales that have been graded around the home or on the lot should not be blocked. These swales are typically constructed to provide drainage toward the driveways, street or other positive outlet. 11) Building pad and slope surfaces should be periodically inspected for rodent activity. Burrowing rodents will reduce slope stabillty by allowing additional water infiltration and channeling of surface runoff Into the slope soils. ~ "'' r -s'•, • '~ CITY Of CARLSBAD INSTRUCTIONS: STORM WATER STANDARDS QUESTIONNAIRE E-34 Development Services Land Development Engineering 1635 Faraday Avenue 760-602-2750 www.carlsbadca.gov To address post-development pollutants that may be generated from development projects, the City requires that new development and significant redevelopment priority projects incolJ)Orate Permanent storm Water Best Management Practices (BMP's) into the project design per the City's Standard Urban Stormwater Management Plan (SUSMP}Jo viewt1!11 SUSMP, refer to the Engineering Standards (Volume 4, Chapter 2) at www.carlsbadca.gov/standards. Initially 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 Stormwater Requirements' or be subject to additional criteria called 'Priority Development Project Requirements'. Many aspects of project site design are dependent upon the storm water standards applied to a project. 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 resubmtt 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 separate completed and signed questionnaire must be 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, you must also complete, sign and submit a Project Threat Assessment Form with construction permits for the project I Please start by completing step 1 and foHow the instructions. Wilen completed, sign the form at the end and submit this with your application to the city. STEP1 TO BE COMPLETED FOR ALL PROJECTS To determine if your project is a priority development project, please answer the following questions: YES NO 1. Is your project LIMITED TO constructing new or retrofitting paved sidewalks, bicycle lanes or trails that meet the following criteria: (1) Designed and constructed to direct storm water runoff to adjacent vegetated areas, or I other non-erodible permeable areas; OR (2) designed and constructed to be hydraulically disconnected from paved streets or roads; OR (3) designed and constructed with permeable pavements or surfaces in accordance with USEPA Green Streets auidance? . 2. Is your project LIMITED TO retrofitting or redeveloping existing paved alleys, streets, or roads that are ✓ designed and constructed in accordance with the USEPA Green Streets guidance? If you answered "yes" to one or more of the above questions, then your project is NOT a priority development project and therefore is NOT subject to the storm water criteria required for priority development projects.
