Our investigation was performed on January 21, 1983. The purpose of this investigation was to evaluate the site from a geologic and soils standpoint, and to provide preliminary recommendations for your use in overall site development. LAYOUT OF REPORT The body of the report contains the text of our findings and recommendations. Details of our field and laboratory work are presented in the Appendices at the end of the report. Key statements in the text are underlined. SCOPE OF SERVICES The scope of services performed in the course of this investigation included: 1. Review of published and unpublished reports and maps pertaining to the subject site and its vicinity; 2. Geologic mapping of the site; 3. Subsurface exploration consisting of three test pits; 4. Laboratory testing of representative soil samples obtained during the field investigation; and, 5. Analysis of field data and preparation of this report, including our findings, conclusions and recommendations. -1- PROPOSED DEVELOPMENT It is our understanding that the proposed development of the rectangular shaped site consists of the construction of a three-story, framed, 3,447 square foot single-family residence, including a 2 car garage, 5 bedrooms and 3 fireplaces. There will be both a slab-on-grade and a raised wooden floor. SITE DESCRIPTION Legal description of the site is: Lot 746 of La Costa Meadows, Unit No. 4 in the County of San Diego, Map No. 7367. Parcel No. is 215-400-05. Lot size is 25,106 square feet (0.576 acres). The subject site is situated on the northwest side of Cazadero Street in Carlsbad, California. The site affords 147.00 feet of frontage along Cazadero Street. The depth of the property is approximately 171 feet. Please reference attached Location Map, Plate No. 1, and the Site Plan, Plate No. 2. Site Photographs are shown on Plate No. 3. The highest portion of the site occurs at the southeast corner with an existing elevation of about 465 MSL. The lowest portion of the site occurs at the northwest corner with an elevation of about 425 MSL. The difference in elevation is therefore about 40 feet. This occurs in a horizontal distance of about 226 feet, thus giving the property an average slope gradient of 17.7 percent. Vegetation consists of sparse low grasses and native medium shrubs and bushes. Large rocks to 2% feet in -2- SITE DESCRIPTION (Continued) diameter occur on the surface along with numerous smaller rocks. Soil material consists mainly of bedrock overlain by six to eighteen inches of silty to clayey gravelly soil, ranging from non-expansive to highly expansive. No surficial water seeps were observed on the pioperty. And no water tables were encountered in any of the test pits. -3- L/oit^^ iPinzi ConiuLting LOCATION MAP BUZA RESIDENCE PROJECT NO. 31005 DATE Jan. 21,, 1983 PLATE NO. i LEGEND zrrj, /»/>/°/?6x, resr PIT / "O tf-7 oo I 1rz r/ CAZADERO DR. /vo torrey pines consulting CM| St. Geolechnical Engineering SITE PLAN BUZA RESIDENCE PROJECT NO. 31005 DATE Jan. 21, 1983 PLATE NO. 2 -5- Looking Northeast Looking torrej pines consulting CM & Gootochnlcal Engirvoofing SITE PHOTOGRAPHS PROJECT NO 31005 DATE [Jan. 21; 1983 PLATE 3 •6- GEOLOGY The subject site is located in Carlsbad, California. The property is underlain by Jurassic and/or Tnassic Metavolcanic Rocks. FIELD AND LABORATORY INVESTIGATION The subsurface investigation consisted of three test pits» trenched with a backhoe to a maximum depth of five feet. The location of test pits are shown on the Site Plan. The test pits were carefully logged and sampled by this firm. Representative samples of the various soils encountered in the test pits were returned to the laboratory for evaluation and appropriate testing. Logs of the test pits and labor- atory test results are presented in Appendices A and B of this report, respectively. -7- CONCLUSIONS AND RECOMMENDATIONS A. General The site is suitable for the proposed development from a geologic and soils engineering standpoint, within the framework of our recommendations. There are, however, certain constraints which must be taken into account. The constraints, conclusions and recommendations follow. B. Slope Stability We recommend that any required permanent cut or fill slopes be constructed to an inclination no steeper than 2.Q horizontal to 1.0 vertical. Placement of fill near the tops of slopes should be carried out in such a manner so as to assure that loose, uncompacted soils are not sloughed over the tops and allowed to accumulate on the slope face. C. Grading and Earthwork 1. Rippability Some difficulty may be encountered when excavating footings with conventional earth-moving equipment. Heavy dozers with a single ripper tooth may have to be utilized when excavating in fractured bedrock material. 2. Recommended Grading Specifications Grading should be performed in accordance with Appendix C, "Recommended Grading Specifications." D. Foundation and Slab Recommendations 1. Recommendations for Expansive Soils Field observations and laboratory testing indicate that the expansion potential of the finished pad soils will be in the highly expansive range. We recommend that these expansive soils be capped with a minimum thickness of three feet of non-expansive soil material and/or incorporated into deeper fill areas. In lieu of a three-foot cap of non-expansive soils, footings and slabs-on-grade may be founded on expansive soils. Recommendations for foundations and slab design, considering the expansive soil conditions and a two/three-story structure, are as follows: a. All exterior footings, including the garage door beam, should be 24 inches deep below slab subgrade, continuous, and contain two No. 5 bars top and bwo No. 5 bars bottom. Interior footings may be 18 and 24 inches deep for two and three-story portions, respectfully. b. Living area floor slabs should be a minimum of four inches thick with 6x6-W2.9/W2.9 welded wire fabric at mid-height over 1 inch of sand over 6 mil visqueen moisture barrier over 4 inches of gravel or sand base. c. Garage floor slabs should be 4 inches thick with 6x6-W2.0/W2.9 welded wire fabric, isolated from stem wall footings, over 4 inches of gravel or sand base. No moisture barrier is required. d. Pre-soak under all slabs to a depth of 24 inches to 5 percent above optimum moisture content. If a raised floor is used or the pad is capped with three feet of non-expansive soil material, exterior footings may then be founded a minimum depth of 18 and 24 inches below lowest adjacent subgrade for two and three-story portions, respectfully. -9- 2. Soil Bearing Pressure Structures may be supported on conventional shallow footings bearing in bedrock, firm natural ground, or compacted fill. At the minimum depths specified, footings may be designed for an allowable dead plus live load bearing pressure of 2,500 and 3000 pounds per square foot (psf) for two and three-story portions, respectfully. This value shall be verified upon completion of the earth- work operations. This value may be increased by one-third for short-term loads, including wind or seismic. Footings should have a minimum width of 15 and 18 inches for two and three-story portions, respectfully. Footings located adjacent to the tops of slopes should be extended sufficiently deep so as to provide at least 5 feet of horizontal cover between the footing and the slope at the footing bearing level. Settlements under building loads are expected to be within tolerable limits for the proposed structures. We estimate post-construction differential settlements across any one building will not exceed 1/2 inch. 3. Lateral Loads Lateral load resistance for the buildings and retaining walls supported on footing foundations may be developed in friction between the foundation bcttoms and the supporting subgrade. An allowable fnational resistance of 200 psf is considered applicable. An additional allow- able passive uniform pressure of 125 pounds per square foot acting against the foundations may be used in design provided the footings are poured neat against the adjacent compacted fill materials or undisturbed natural soils. When combining passive pressure and fnational resistance, the passive pressure component should be reduced by one- third. For design of isolated poles, such as flagpoles, the allowable passive earth pressure may be increased by 100 percent. -10- E. Pavements - On-site soils range from poor to good subgrades. R-value testing and pavement design should be performed after rough subgrade for driveways and parking areas is achieved. Tentative pavement design considerations are presented below: 2 VAC over 7" AB over 12" SG Notes: (a) AC is type B asphaltic concrete meeting re- quirements of Section 39 of State of California Standard Specifications, 1978. (b) AB is Class 2 aggregate base in accordance with Section 26 of State of California Standard Specifications, 1978. AB shall be compacted to 95 percent relative compaction (c) SG is imported non-expansive soil material compacted to 95 percent relative density. (d) Prior to placing the aggregate base, the sub- grade soils should be rolled with smooth-wheeled compactor to produce a firm, smooth, non-yielding surface. If you should require any clarification of the above, please do not hesitate to contact this office. Very truly yours, TORREY PINES CONSULTING Dennis E. Zimmerman, P.E C26676 Project Engineer cc: (4) Addressee (1) Field Copy (1) File Copy -11- LIMITATIONS Conclusions and recommendations made in this report are based on the assumption that the soil and geologic conditions do not deviate appreciable from those disclosed by the test pits. If variations are encountered during construction, TORREY PINES CONSULTING should be notified so we may make supplemental recommendations, if this should be required. Evaluation of soil materials for support of structures includes continuous inspection during grading. The soil engineer should continue his services through inspection of grading, including construction of fills, foundation excavations, trench backfill, backfill behind retaining walls, and installation of necessary drainage systems. -12- APPENDIX A SUBSURFACE INVESTIGATION The investigation was continuously supervised, test pits logged, and samples obtained by this firm for laboratory testing.

A Soils Engineer shall be the Owner's representative to inspect the construction of fills. Excavation and the placing of fill shall be under the direct inspection of the Soils Engineer, and he shall give written notice of conforraance with the specifications upon com- pletion of grading. Deviations from these specifications will be permitted only upon written authori2ation from the Soils Engineer. No deviation from these specifications will be allowed, except where specifically superceded in the Preliminary Geotechnical Investigation Report, or in other written communication signed by the Soils Engineer. II. SCOPE The placement of fill by the Contractor shall include all clearing and grubbing, removal of existing unsatisfactory material, preparation of the areas to be filled, spread- ing and compaction of fill in the areas to be filled, and all other work necessary to complete the grading of the filled areas. III. MATERIALS A) Materials for compacted fill shall consist of any material that, in the opinion of the Soils Engineer, is suitable for use in constructing fills. No material of a perishable, spongy, or unsuitable nature shall be used in filling. -21- B) Material placed within 24 inches of rough lot grade shall be select material that swells less than 3% when compacted as hereinafter specified for compacted fill and when subjected to an axial pressure of 144 psf, unless expansive soil recommendations are given in this report. C) During grading operations, soil types other than those analyzed in the report of the soil investigation may be encountered by the Contractor. The Soil Engineer shall be consulted to determine the suitability of these soils. IV. COMPACTED FILLS A) GENERAL 1. Unless otherwise specified, fill material shall be compacted by the Contractor while at a moisture content near the optimum moisture content and to a density that is not less than 90% of the maximum density determined in accordance with ASTM Test No. D-1557-70. 2. Potentially expansive soils may be used in fills below a depth of 24 inches and shall be compacted at a moisture content greater than the optimum moisture content for the material, unless recommendations for expansive soils are given in this report. B) CLEARING AND PREPARING AREAS TO BE FILLED 1. All objectionable material shall be disposed of by the Contractor. 2. All objectionable material shall be removed by the Contractor from the surface upon which the cill is to be placed, and any loose and porous soils shalL be removed to the depth specified. The surface shall then be scarified to a minimum depth of 6 inches and recompacted. 3. Prior to grading, the site should be cleared of surface obstructions and stripped of brush and vege- tation . Obstructions which extend below finish grade should be removed and replaced with compacted fill. -22- Vegetation and debris from the clearing operation should be removed from the site. 4. All existing on-site soil and bedrock materials are generally suitable for reuse as fill. Fill materials should not, in general, contain rocks or cobbles greater than 6 inches in largest dimension. However, larger rock fragments may be incorporated into the lower portion of fills, provided the method of spacing and compaction are approved by the Soils Engineer. 5. Where fills are constructed on slobes steeper than 5 horizontal to 1 vertical, the slope of the original ground on which the fill is to be placed shall be bench- ed and keyed by the Contractor as directed by the Soils Engineer. The benches and keys shall extend completely through the soil mantle and into the underlying formational materials. 6. Compaction of slopes should be achieved by over- building the slopes laterally, then cutting back to the design line and grade, or by back-rolling with sheeps- foot at frequent intervals as the fill is placed, followed by final rolling of the entire slope. Feathering of fill over the tops of slopes should not be permitted. All fills should be placed and grading performed in accord- ance with applicable local grading ordinances and this report. 7. After the foundation for the fill has been cleared and scarified, it shall be compacted as specified for fill. C) PLACING, SPREADING, AND COMPACTION OF FILL MATERIAL 1. The fill material shall be placed by the Contractor in layers that, when compacted, shall not exceed 6 inches. Each layer shall be spread evenly and shall be thoroughly mixed during the spreading to obtain uniformity of material in each layer. 2. When the moisture content of the fill material is above that specified by the Soils Engineer, the fill -23- material shall be aerated by the Contractor by blading, mixing or other satisfactory methods until the moisture content is as specified. 3. When the moisture content of the fill material is below that specified by the Soils Engineer, water shall be added by the Contractor until the moisture content is as specified. 4. After each layer has been placed, mixed and spread evenly, it shall be thoroughly compacted by the Contractor to the specified density. Compaction shall be accomplished by suitable compacting equipment. 5. Utility trenches should be backfilled with compacted fill. Backfill material should be placed in lift thick- nesses appropriate to the type of compaction equipment utilized and compacted to 90 percent by mechanical means. 6. If a daylight pad should occur where the building will partially be underlain by compacted fill and partly by bedrock and/or natural soil, the cut portion of the lot should be overexcavated to a depth of at leat 2^ feet below pad subgrade and replaced with compacted fill. This overexcavation should be extended a minimum of 5 feet beyond the edge of the perimeter footings. V. GRADING CONTROL A) Observations and compaction tests shall be made by the Soils Engineer during grading so that he can state that the fill was constructed in accordance with the specifications. B) The Soils Engineer shall make field density tests in accordance with ASTM Test No. D-1556-64. When these tests indicate that the density is below the specified density, that portion shall be reworked until the specified density has been obtained. -24- VI. CONSTRUCTION OBSERVATIONS A) During construction, the Contractor shall properly grade all excavated surfaces to provide positive drainage and prevent ponding of water. He shall control surface water to avoid damage to adjoining properties or to finish- ed work on the site. The Contractor shall take remedial measures to prevent erosion of freshly graded areas and until such time as permanent drainage and erosion control measures have been installed. B) After completion of grading and the Soils Engineer has finished his observations of the work, no further excavation or filling shall be done except under the observation of the Soils Engineer. -25- 1/30/80 LEUCADIA COUNTY WATER DISTRICT APPI 1CATIOH FOR SEUER SERVICE Ov/nei 's Narre Mail ing Address Service Address ^ 60-Phone -Woo dbur-n-Qr-iv e O Cazadero Drive Tract Description-- lot 746>vMeadows #4 Assessor's Parcels-No. ^^ _•? /,5~~- y^ Type of Building lateral Size. 4" Extra Footage: single family No Units ] Connection Fee $ 1,500.00 6" 8" Saddle Easement Connection (Pre-pd 200.00} @ $ Extra Depth: @ $ .1.300.,00 Amount Rec'd $ 1300.00 Ck.

The total charges must be paid to the District at the time the application is submitted. If a service lateral is required, it will be installed by the Leucadia County Water District. The service lateral is that part of the sewer system that extends from the main collection line in the street (or easement) to the point in the street (at or near the applicant's property line) where the service lateral is connected to the applicant's building sewer. The applicant is responsible for the construction, at the applicant's expense, of the sewer pipeline (building sewer) from the appli- cant's plumbing to the point in the street (or easement) where a connection is made to the service lateral. The connection of the applicant's building sewer to the service lateral shall be made by the applicant ai his expense. The connection must be iriade in conformity with the District's specifications, rules and regulations; and IT MUST BE INSPECTED AND APPROVED BY THE DISTRICT BEFORE THE SEWER SYSTEM MAY BE USED BY THE APPLICANT. THE APPLICANT, OR HIS AUTHORIZED REPRESENTATIVE, MUST NOTIFY THE DISTRICT AT THE TIME INSPECTION IS DESIRED. ANY CONNECTION MADE TO THE SERVICE LATERAL OR COLLEC^ TION LINE WITHOUT PRIOR APPROVAL AND INSPECTION BY THE DISTRICT WILL BE CONSIDERED INVALID AND WILL NOT BE ACKNOWLEDGED. The prorated sewer service fee is based upon the date the District estimates that . service will begin and covers the balance of the fiscal year. There will be no additional fee or refund if service actually commences on a different date. For succeeding fiscal years, the sewer service fee will be collected on the tax roll in the same manner as property taxes.
