The objectives of the investigation were to evaluate the existing soils conditions and provide recommendations for the proposed development. SCOPE OF SERVICES The following services were provided during this investigation: O Site reconnaissance and review of published geologic, seismological and geotechnical reports and maps pertinent to the project area O Subsurface exploration consisting of four (4) boreholes within the limits of the proposed area of development. The boreholes were logged by our Staff Geologist. O 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. O Laboratory testing of samples representative of the types of soils encountered during the field investigation O Geologic and engineering analysis of the field and laboratory data, which provided the basis for our conclusions and recommendations O Production of this report, which summarizes the results of the above analysis and presents our findings and recommendations for the proposed development SITE DESCRIPTION AND PROPOSED CONSTRUCTION The subject site is an irregular- shaped residential lot located on the east side of Neptune Avenue, in the City of Encinitas, California. The property, which encompasses an area of 10,360 square feet is occupied by a two -story house. The site slopes gently to the west. Vegetation consisted of grass, a few trees and shrub. Site boundaries include Neptune Avenue to the west, an easement to the east and residential parcels to the remaining directions. It is our understanding that the existing structure will be demolished and replaced with another single- family residence and an accessory guesthouse. The structures will be one and two -story, partially over a basement, wood - framed and founded on continuous footings with slab -on -grade floors. 4 TENAJA CA, LLC PROJECT NO. 08- 1147A3(2) FIELD INVESTIGATION AND LABORATORY TESTING On December 4 and 10, 2008, four (4) boreholes were drilled to a maximum depth of approximately 13.0 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 density and optimum moisture content, direct shear, particle size analysis and expansion index tests. These tests were performed in general accordance with ASTM standards and other accepted methods. Page L -1 and Plate No. 2 provide a summary of the laboratory test results. GEOLOGY Geologic Settin> The subject site is located within the southern portion of what is known as the Peninsular Ranges Geomorphic Province of California The coastal areas of the province in Encinitas are typically made up of Pleistocene marine terrace deposits (Qt). Site Stratieranhv 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 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 generally 6 to 12 inches thick and consisted of dark brown, silty sand that was dry, loose and porous in consistency with minor amounts of organics (roots and rootlets). Slopewash ( Osw ) Slopewash was encountered below the topsoil to a depth of approximately 2 feet and consisted of loose sand with silt that was damp. 5 TENAJA CA, LLC PROJECT NO. 08- 1147A3(2) Marine Terrace Deposits ( Ot ) Terrace deposits were observed below the slopewash layer. They generally consisted of tan, silty fine sand. The moisture content ranged from damp to moist and the materials were medium dense to dense in consistency. 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 3 miles (5 kilometers) west of the site. 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 (Egseach 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 0.45g. 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 0.29g. 11 TENAJA CA, LLC PROJECT NO. 08- 1147A3(2) 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 investigation and evaluation of the collected information, we conclude that the proposed structural development is feasible from a geotechnical standpoint provided the recommendations provided in this report will be properly implemented during structural development. Based on the low expansion potential of the granular near - surface soils, it is our opinion that the building pad may be constructed using the on -site materials. In order to provide a uniform support for the structures, overexcavation and recompaction of the structural portion of the building pad will be required. The foundations 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 sedimentary bedrock, which underlies the site. However, loose topsoil and slopewash were 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, remedial grading of these near- surface soils (including overexcavation and recompaction) will be required. 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 indicate a low expansion potential for the foundation soils. Groundwater Static groundwater was not encountered to the depths of the boreholes. The subject site is located at an elevation of approximately 90 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. E TENAJA CA, LLC PROJECT NO. 08- 1147A3(2) 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. GRADING AND EARTHWORK Based upon the proposed construction and the information obtained during the field investigation, we anticipate that the proposed structures will be founded on continuous footings, which are supported by properly compacted fill or dense sandstone of the Terrace Deposits Formation. The following grading and earthwork recommendations are based upon the limited geotechnical investigation performed, and should be verified during construction by our field representative. Clearing and Grubbing All areas to be graded or to receive fill and/or structures should be cleared of vegetation. 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 as recommended in the Method and Criteria of Compaction section of this report. Structural Improvement of Soils Information obtained from our field and laboratory analysis indicates that loose topsoil and slopewash cover the site to a depth of approximately 2 feet below existing grade. These loose surficial soils are susceptible to settlement upon loading. Based upon the soil characteristics, we recommend the following: * All topsoil, slopewash and other loose natural soils should be completely removed from areas, which are planned to receive compacted fills and/or structural improvements. The bottom of the removal area should expose competent materials as approved by ECSC &E geotechnical representative. Prior to the placement of new fill, the bottom of the removal area should be scarified a minimum depth of 6 inches, moisture- conditioned within 2 percent above the optimum moisture content, and then recompacted to at least 90 percent relative compaction (ASTM D -1557 test method). * Overexcavation should be completed for the structural building pad to a minimum depth of 4 feet below existing grade. The limit of the required area of overexcavation should be extended a minimum of 5 feet laterally beyond the perimeter footing (building footprint). * For non - structural areas, such as driveways, we recommend overexcavation to a minimum depth of 2 feet below existing grade. E TENAJA CA, LLC PROJECT NO. 08- 1147A3(2) • Soils utilized as fill should be moisture- conditioned and recompacted in conformance with the following Method and Criteria of Compaction section of this report. The depth and extent of any overexcavation and recompaction should be evaluated in the field by a representative of ECSC &E. Transitions Between Cut and Fill The proposed structures are anticipated to be founded in properly compacted fill or dense sandstone of the Terrace Deposits Formation. Cut to fill transitions below the proposed structures should be eliminated during the earthwork construction as required in the previous section. Method and Criteria of Compaction Compacted fills should consist of approved soil material, free of trash debris, roots, vegetation or other deleterious materials. Fill soils should be compacted by suitable compaction equipment in uniform loose lifts of 6 to 8 inches. Unless otherwise specified, all soils subjected to recompaction should be moisture -conditioned within 2 percent of the optimum moisture content and recompacted to at least 90 percent relative compaction per ASTM test method D1557. The on -site soils, after being processed to delete the aforementioned deleterious materials, may be used for recompaction purposes. Should any importation of fill be planned, the intended import source(s) should be evaluated and approved by ECSCE prior to delivery to the site. Care should be taken to ensure that these soils are not detrimentally expansive. Erosion Control Due to the granular characteristics of the on -site soils, areas of recent grading or exposed ground may be subject to erosion. During construction, surface water should be controlled via berms, sandbags, 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 grading, all excavated surfaces should exhibit positive drainage and eliminate areas where water might pond. Standard Grading Guidelines Grading and earthwork should be conducted in accordance with the standard -of -- practice methods for this local, the guidelines of the current edition of the Uniform Building Code, and the requirements of the jurisdictional agency. Where the information provided in the geotechnical report differs from the Standard Grading Guidelines, the requirements outlined in the report shall govern. 10 TENAJA CA, LLC PROJECT NO. 08- 1147A3(2) FOUNDATIONS AND SLABS a. Continuous and spread footings are suitable for use and should extend to a minimum depth of 24 inches for the two -story over basement portion of the structure into the dense sandstone of the Terrace Deposits Formation, and 18 inches for the only two -story portion into properly compacted fill soils. Continuous footings should be at least 18 and 15 inches in width respectively and reinforced with a minimum of 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. Footings for the proposed one -story guesthouse should be at least 12 inches deep and 12 inches wide and reinforced as above. The above reinforcement is based on soil characteristics and is not intended to be in lieu of the project structural engineer requirements. b. Interior concrete floor slabs should be a minimum 5 inches thick for the two -story over basement and 4 inches for the one -story guesthouse. Reinforcement should consist of 43 bars placed at 16 inches on center each way within the middle third of the slabs by supporting the steel on chairs or concrete blocks "dobies ". The slabs 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. c. Where moisture sensitive floor coverings are anticipated over the slabs, the 10 -mil plastic moisture barrier should be underlain by a capillary break at least 2 inches thick, consisting of coarse sand, gravel or crushed rock not exceeding 3/4 inch in size with no more than 5 percent passing the #200 sieve. d. An allowable soil bearing value of 2,500 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 properly compacted fill soils or the dense sandstone of the Terrace Deposits Formation. This value may be increased by 960 psf and 440 psf for each additional foot of depth and width respectively to a maximum of 4,000 lb/ft2. e. Lateral resistance to horizontal movement may be provided by the soil passive pressure and the friction of concrete to soil_ An allowable passive pressure of 300 pounds per square foot per foot of depth may be used. A coefficient of friction of 0.40 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 soils is normal and should be anticipated. Because of the type and minor thickness of the fill soils anticipated under the proposed footings and the light building loads, total and differential settlements should be within acceptable limits. TEMPORARY SLOPES For the excavation of foundations and utility trenches, temporary vertical cuts to a maximum height of 4 feet may be constructed in fill or natural soil. Any temporary cuts beyond the above height 11 TENAJA CA, LLC PROJECT NO. 08- 1147A3(2) constraints should be shored or further laid back following a 1:1 (horizontal to vertical) slope ratio. OSHA guidelines for trench excavation safety should be implemented during construction. RETAINING WALLS Cantilevered retaining walls should be designed for an "active" lateral earth pressure of 35 psf/ft (35 pcf EFP) for approved granular backfrll and level backfrll conditions. Where cantilevered walls support 2:1 (hor:vert) sloping backfrll, the equivalent active fluid pressure should be increased to 45 pcf. Cantilever walls subject to uniform surcharge loads should be designed for an additional uniform lateral pressure equal to one -third (1 /3)the anticipated surcharge pressure. Restrained walls, such as basement walls should be designed utilizing an "at- rest" earth pressure of 60 psf/ft (60 pcf EFP) for approved granular and level backfill. Restrained walls subject to uniform surcharge loads should be designed for an additional uniform lateral pressure equal to one -half (1/2) the anticipated surcharge. Retaining wall footings should be embedded a minimum of 18 inches below the lowest adjacent grade. Retaining walls that are to be located near the top of slopes should be designed to allow a minimum daylight distance of 7 feet laterally from the outside edge of the footing to the slope face. Soil design criteria, such as bearing capacity, passive earth pressure and sliding resistance as recommended under the Foundation and Slab Recommendations section, may be incorporated into the retaining wall design. The design and location of retaining walls should be reviewed by our firm for conformance with our recommendations. Footings should be reinforced as recommended by the structural engineer and appropriate back drainage provided to avoid excessive hydrostatic wall pressures. As a minimum we recommend a fabric- wrapped crushed rock and perforated pipe system. At least 2 cubic feet per linear foot of free - drainage crushed rock should be provided. The remaining wall backfrll should consist of approved granular material. This fill material should be compacted to a minimum relative compaction of 90 percent as determined by ASTM D -1557 test method. Flooding or jetting of backfrll should not be permitted. Granular backfrll should be capped with a minimum 18 inches of relatively impervious fill to seal the backfrll and prevent saturation. It should be noted that the use of heavy compaction equipment in close proximity to retaining structures can result in wall pressures exceeding design values and corresponding wall movement greater than that associated with active or at -rest conditions. In this regard, the contractor should take appropriate precautions during the backfrll placement. 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 backfrll should be uniformly watered and 12 TENAJA CA, LLC PROJECT NO. 08- 1147A3(2) 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 I percent is recommended in hardscape areas. For earth areas, a minimum gradient of 5 percent away from all structures 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 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 PLAN REVIEW Our firm should review the foundation plans during the design phase to assure conformance with the intent of this report. 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. LIMITATIONS OF INVESTIGATION Our investigation was performed using the skill and degree of care ordinarily exercised, under similar circumstances, by reputable soils engineers and geologists practicing in this or similar localities. No other warranty, expressed or implied, is made as to the conclusions and professional advice included in this report. This report is prepared for the sole use of our client and may not be assigned to others without the written consent of the client and ECSC &E, Inc. The samples collected and used for testing, and the observations made, are believed representative of site conditions; however, soil and geologic conditions can vary significantly between exploration trenches, boreholes and surface exposures. As in most major projects, conditions revealed by construction excavations may vary with preliminary findings. If this occurs, the changed conditions must be evaluated by a representative of ECSC &E and designs adjusted as required or alternate designs recommended. This report is issued with the understanding that it is the responsibility of the owner, or of his representative to ensure that the information and recommendations contained herein are brought to the attention of the project architect and engineer. Appropriate recommendations should be incorporated into the structural plans. The necessary steps should be taken to see that the contractor and subcontractors cant' out such recommendations in the field. 13 TENAJA CA, LLC PROJECT NO. 08- 1147A3(2) The findings of this report are valid as of this present date. However, changes in the conditions of a property can occur with the passage of time, whether they are due to natural processes or the works of man on this or adjacent properties.

The basic site design concept for the new home is similar to the original site design in that the main living level will be constructed over a basement level garage close to the existing grade at Neptune Avenue. The new basement level will be below the street and the original street level garage and will require a drainage sump pump to be installed to prevent the garage level from flooding during a rain event. Existing surface runoff patterns will be generally left as they are, flowing from the high easterly end of the site, westerly toward Neptune Avenue. 100 Year peak flow runoff calculations were performed to determine storm water runoff qw itities in accordance with the County of San Diego Hydrology Manual. The site is approximately 60`,o impervious corresponding to a runoff coefficient of 0.79 for a soil type "D" (soil type specified by City of Encinitas policy). The peak 100 year flow to the storm drain sump pump was calculated to be 0.16 cfs. The total 100 year peak flow from the site draining onto Neptune Avenue is 1.30 cfs corresponding to a 5 minute time of concentration and 6.6 in /hr rainfall intensity. The proposed project adds only 50 square feet of impervious surface area from the pre- construction condition (0.5% of the project site). The increase in storm runoff from the proposed new home construction (0.002 cfs) is considered insignificant in terms of any kind of drainage design consideration issue. All of the site runoff is directed to two planters at the northwest and southwest corners of the site where bio- filtration of runoff can occur prior to discharge to Neptune Avenue.
