Cd/DL/RPC99220.232(FINAL-8/29/02)3 ATTACHMENT"A" Resolution No.PC 2002-32 Case No.99-220 TM/CDP/EIA FINDINGS FOR A TENTATIVE MAP STANDARD: Section 66474 of the California Government Code requires that the authorized agency approve an application for a Tentative Map unless, based upon the information presented in the application and during the Public Hearing, the authorized agency makes any of the following findings of fact: a. That the proposed map is not consistent with applicable general and specific plans as specified in Section 65451 of the Subdivision Map Act. Facts:. The proposed Tentative Map includes the subdivision of approximately 1.09 acres into six lots comprised of five single family residential lots and one private road lot. There is no applicable specific plan associated with the project site. The General Plan allows a density range of 5.01-8.0 dwelling units per acre in the R-8 zoning designation with a midrange density of 6.5 dwelling units per net acre. Discussion: The project density is consistent with the allowable density range of the R-8 zone. Based on a net acreage of.865 acres (which excludes the proposed road dedication and private street),the subdivision results in a density of 5.6 dwelling units per acre,which is below the mid-range density of 6.5 du/acre permitted in the R-8 zone. Conclusion: The Planning Commission finds that the proposed map is consistent with the General Plan subject to the required specific and standard conditions contained in the approved resolution. b. That the design or improvement of the proposed subdivision is not consistent with applicable general and specific plans. Facts:. Chapter 24.12 of the Municipal Code sets forth design standards for subdivisions and Chapter 30.16 of the Municipal Code sets forth technical standards, such as lot width and depth requirements for the R-8 Zone in which the site is located. Section 24.12.020 of the Municipal Code includes provisions to suspend design requirements in a particular case as long as the application for such suspension shows that there are special circumstances or conditions affecting the property in question,also,that such suspension,if granted,will not be materially detrimental to the public welfare or injurious to other property in the immediate vicinity. Discussion: The five residential lots are proposed with net acreage ranging from 7188 square feet to 7965 square feet,which conforms with the minimum lots size of 5400 square feet required pursuant to development standards of the R-8 zone in which the site is located. The lot widths and depths have been reviewed,and, except for lot depth on Lot 5, appear to Cd/DL/RPC99220.232(FINAL- 8/29/02)4 be in conformance with the standards for the R-8 zone which requires a minimum lot width of 60 feet,a minimum cul-de-sac lot width of 30 feet and a minimum lot depth of 90 feet. Lot 5 is proposed with a depth of 80 feet.A request to suspend the standard 90 foot lot depth design requirement within the R-8 zone is included as part of the application to authorize the 80 foot depth proposed on Lot 5. In summary, the special circumstances applicable to the need for the reduced lot depth are 1) the long rectangular"L" shaped configuration of the existing site which maintains only 100 feet of frontage on Rubenstein; 2) one access point for the five lots forces the road width to the minimum 26 foot width currently proposed; 3) the access point on Rubenstein is located on the site's northerly boundary to avoid sight distance conflicts to the south near where several streets intersect at irregular patterns; 4) offsetting the cul-de-sac to meet the depth would affect the usable yard areas of other lots and reduce the buffer proposed between Lot 2 and the existing residential development to the south. The suspension of design requirements is acceptable based on the above justification, as well as the fact that 1) the lot sizes (7188 - 7965 square feet) for the development far exceed the 5400 square foot minimum net lot area required in the R-8 zone; 2) the other lot depths (approx. 92' - 102') exceed the 90 foot minimum; and 3) the lot widths(approx.68' -94')exceed the 60 foot minimum. Conclusion: The Planning Commission finds that there are special circumstances or conditions affecting the property in question,also,that such suspension,if granted,will not be materially detrimental to the public welfare or injurious to other property in the immediate vicinity. Additionally,the Planning Commission finds that, with the suspension of design requirements for Lot Depth to authorize a depth of 80 feet on the proposed Lot 5 as part of the project, the proposed subdivision conforms to the General Plan since all technical requirements are pursuant to the City's Subdivision Ordinance C. That the site is not physically suitable for the type of development. Facts:. The Tentative Map proposes to provide lot sizes that conform to provisions of the R- 8 Zone (5400 sq. ft. min.). The Tentative Map indicates the conceptual grading to create future building pads which will adequately accommodate single family residences. An Environmental Initial Study was prepared for the project which determined that the proposed project will not result in any significant adverse environmental impacts. Discussion:To accommodate flat pads in the easterly portion of the project(Lots 3,4 & 5) and split pads at the westerly portion of the site (Lots 1 and 2), project grading will include 400 cubic yards of cut and 1200 cubic yards of fill with 800 cubic yards of import. Fill heights are maintained at a minimum of two feet for the flat pads and four feet for the split pads. The split pad designs for the lots minimize the fill amounts required to create usable pads. Conclusion: The Planning Commission finds that the site is physically suitable to accommodate the future development of five single family residences, and that, with the suspension of the standard 90 foot depth requirement on Lot 5, the subdivision is designed, or has been conditioned,to comply with Municipal Code development standards. Cd/DL/RPC99220.232(FINAL-8/29/02)5 d. That the site is not physically suitable for the proposed density of development. Facts: The application is a request to subdivide.865 net acres into six lots comprised of one private road lot and five single family residential lots. With the authorization of an 80 foot lot depth on Lot 5,each lot complies with the minimum lot area,lot dimensions and all other applicable design standards of the subject R-8 zone as set forth in the Municipal Code. The project density is 5.6 dwelling units per acre, which is below the mid-range density of 6.5 du/acre permitted in the R-8 zone. Discussion:The total number of dwelling units and the project density,in addition to being within the allowable range for the R-8 zone,is suitable since project design indicates that the allowed single family homes can be accommodated on the resulting graded pads and conform to the setback requirements of the R-8 Zone. Conclusion: The Planning Commission finds that the site is physically suitable for the density of development proposed. e. That the design of the subdivision or the proposed improvements are likely to cause substantial environmental damage or substantially or avoidably injure fish or wildlife or their habitat Facts:. An Environmental Initial Study was prepared by the City's Environmental Consultant,Curtis Scott Englehorn and Associates for the original six lot project design; the Initial Study was subsequently revised by the City's Environmental Coordinator to reflect the revised five lot design with sole access off of Rubenstein Avenue. Discussion: The Initial Study determined the project would not result in any significant adverse environmental impacts. A Negative Declaration was recommend for adoption in conjunction with the project approval. Conclusion: The Planning Commission finds that the project will not cause substantial environmental damage or substantially or avoidably injure fish or wildlife or their habitat. f. That the design of the subdivision or the type of improvements is likely to cause serious public health problems. Facts:. The applicant has submitted "will service"letters to indicate that the Water, Sewer, Fire and School agencies can provide adequate service and utilities to the project site. Discussion:No evidence has been submitted to indicate that a serious public health problem would occur should the Tentative Map be recorded and future residences be constructed. Conclusion: The Planning Commission finds that the design of the subdivision can be adequately serviced with necessary utilities and the project will not cause any serious public health problems. Cd/DL/RPC99220.232(FINAL-8/29/02)6 g. That the design of the subdivision or the type of improvements will conflict with easements, acquired by the public at large, for access through or use of, property within the proposed subdivision. In this connection,the authorized agency may approve a map if it finds that alternate easements, for access or for use, will be provided, and that these will be substantially equivalent to ones previously acquired by the public. This subsection shall apply only to easements of record or to easements established by judgment of a court of competent jurisdiction and no authority is hereby granted to a legislative body to determine that the public at large has acquired easements through or use of property within the proposed subdivision. Facts:. The Tentative Map indicates that adequate access to each of the residential lots can be provided in conformance with City standards.All other known easements for utilities or access are indicated on the Tentative Map and will remain or be relocated for access to public utilities. Discussion: The design of the Tentative Map will not conflict with any easements for utilities or roadways. The Tentative Map has been conditioned to require all access easements and utilities to be shown on the Final Map in accordance with City standards and the servicing utilities'requirements. Conclusion: The Planning Commission finds that the design of the subdivision and future improvements will not conflict with any public easements nor hinder access to,or the use of, property within the proposed subdivision. Cd/DL/RPC99220.232(FINAL-8/29/02)7 FINDINGS FOR A COASTAL DEVELOPMENT PERMIT STANDARD: Section 30.80.090 of the Municipal Code provides that the authorized agency must make the following findings of fact, based upon the information presented in the application and during the Public Hearing,in order to approve a coastal development permit: 1. The project is consistent with the certified Local Coastal Program of the City of Encinitas; and 2. The proposed development conforms with Public Resources Code Section 21000 and following(CEQA)in that there are no feasible mitigation measures or feasible alternatives available which would substantially lessen any significant adverse impact that the activity may have on the environment;and 3. For projects involving development between the sea or other body of water and the nearest public road,approval shall include a specific finding that such development is in conformity with the public access and public recreation policies of Section 30200 et. seq. of the Coastal Act. Facts:. The Coastal Development Permit is requested for the subject project relative to the proposed subdivision of 1.09 acres into six lots, the proposed construction of five single family homes and associated improvements. An Environmental Initial Study was completed for the original project design by the City's Environmental Consultant, Curtis Scott Englehorn and Associates and further revised by the City's Environmental Coordinator. The project site is located within the R-8 zone and the Coastal Zone. The City's General Plan and Municipal Code are applicable components of the City's Local Coastal Program. Discussion: Related to Finding No. 1, the R-8 Zone expressly allows for single family homes. With the suspension of the standard 90 foot lot depth requirement for the proposed Lot 5, the project conforms or is conditioned to conform with density and development standards of the R-8 Zone and the Municipal Code. Additionally, as depicted on the building drawings the five homes are proposed with different elevations; architectural features and materials and are considered dissimilar in design and exempt from Design Review pursuant to Section 23.08.03013.7 of the Municipal Code. The different footprints create a different elevation for each home, and each home is proposed with different architectural styles, window treatments, flat and pitched roof structures, varying rooflines, varying roofing materials, wood siding and/or stucco treatments, therefore the homes meet the custom home exemption. Related to Finding No. 2, the Environmental Initial Study concluded that the project would not result in a significant impact to the environment. The project design is an alternative to a previous design which proposed an additional lot and utilized access from both Brahms Road and Rubenstein Avenue. Cd/DL/RPC99220.232(FINAL-8/29/02)8 Related to Finding No. 3, the subject site is located on the east side of Rubenstein Avenue, which is not between the sea or other body of water and the nearest public road, therefore Finding No.3 is not applicable to the subject project. Conclusion: The Planning Commission finds that 1) the project is consistent with the certified Local Coastal Program of the City of Encinitas; 2) that there are no feasible mitigation measures or alternatives available which would substantially lessen any significant adverse impact that the activity may have on the environment; and 3) Finding No. 3 is not applicable to the project since it is not located between the sea or other body of water and the nearest public road.

December 9, 2003 Kachay Co. 12230 El Camino Real #320 San Diego, CA. 92130 Subject : Project No. 02-1167132 Report of Engineering Observation of Grading and Testing of Compacted Fill Proposed Five-Lot Residential Subdivision Site 1573 Rubenstein Avenue Encinitas, California Gentlemen : In accordance with your request, we have provided engineering services in conjunction with the grading for the five proposed residential building sites on subject property, more specifically referred to as being Lot Nos. 1 to 5, inclusive of TM 99-220 (Assessor's Parcel Nos. 280-084-10 and 11), in the City of Encinitas, State of California. DESCRIPTION OF PROJECT The proposed development consists of grading of the site to receive five residences. SCOPE OF WORK Our services included - Providing engineering observation of the grading operation; - performing field density tests in the placed and compacted fill; - performing laboratory tests on samples of the material used for fill; and - providing professional opinions regarding the contractor's adherence to the geotechnical portion of the plans and specifications. Project No. 02-1167D2 Kachay Co 12/09/03 Page 2 1573 Rubenstein Avenue SUMMARY OF GENERAL EARTHWORK AND TESTING Site preparation, grading, compaction and testing were accomplished during the period between November 3 and 25, 2003, inclusive. In our opinion, based on our observation and testing, the earthwork performed during that period was in substantial conformance with the recommendations as presented in the report entitled "Geotechnical Investigation — Proposed Five-Lot Residential Subdivision, 1573 Rubenstein Avenue, Encinitas, California" prepared by our firm, dated October 25, 2002. Prior to grading, the existing structures and improvements on the site were demolished and the debris hauled away and disposed of offsite. During the grading operation, certain earthwork operations were observed. These included : The removal of the upper loose soils and soils disturbed by the demolition process that remained below finished grade. Depth of removal varied from 3 to 5 feet below existing grade. - The inspection of the keyways for the proposed fill slope on Lot Nos. 1 and 2. The keyways were on the order of 4 feet below existing ground, and are at least 12 inches into competent natural soils. - The over-excavation and recompaction of the natural soils within the residential lots to a depth of 3 feet below finished grade. The elevations of fill at which the tests were taken and the final test results are presented on pages T-1 to T-4, under"Table of Test Results". The laboratory determinations of the maximum dry densities and optimum moisture contents of the fill soils are set forth on page L-1, under "Laboratory Test Results". The approximate location of the compacted filled ground and field density tests are presented on Figure No. 1, entitled, "Approximate Location of Compacted Filled Ground". The results of the tests and observations indicate that the fill soils placed on the sites have been compacted to at least 90 percent of maximum dry density. Test results indicate that these soils will support the proposed residential buildings without detrimental settlement, and the sites are adequate for their intended use as support to the proposed residential buildings. SUMMARY OF FINISH GRADE SOIL CONDITIONS Observations and laboratory tests indicated that the soils within 3 feet below finished grade on the sites are classified as having LOW expansion potential (Expansion Index Project No. 02-1167D2 Kachay Co. 12/09/03 Page 3 1573 Rubenstein Avenue = 38). RECOMMENDATIONS Foundation for Structures It is recommended that a safe allowable soil bearing value of 1,800 pounds per square foot (total dead plus live loads) be used for the design of continuous or spread footings that are a minimum of 12 and 24 inches in minimum horizontal dimension, respectively, and are embedded at least 12 inches (for single-story) or 18 inches (for two stories), into the competent natural or compacted fill soils. It is recommended that all continuous footings be reinforced with 2 #5 rebars; one rebar located near the top, and the other rebar near the bottom of the footings. Isolated pier footings should be a minimum of 24 inches square and embedded at least 18 inches below the lowest adjacent final grade, and should be reinforced with a minimum of two #5 rebars in both directions It is recommended that concrete slab-on-grade be at least 4 inches in thickness. The concrete slab should be reinforced with a minimum of#3 rebars @ 24 inches on center, in both directions. The concrete slab should be underlain by 4 inches of clean sand. It is recommended that foundation for the proposed structures be setback at least 7 feet from the top of fill slope. Foundations placed closer to the top of fill slope than 7 feet should be deepened such that the outer edge along the bottom is at least 7 feet back from the face of slope at that level. Concrete Flatwork It is recommended that the proposed concrete flatwork founded be 3 '/2 inches in thickness, and be reinforced with 6x6-10/10 welded wire mesh at mid-height, underlain by 4 inch of sand base. '/2-inch expansion joints and '/4" weakened plane contraction joints should be provided at 15-foot and 5-foot intervals,respectively. Foundation Trench Excavation Inspection It is recommended that the foundation trench excavations for the proposed structure be inspected by our firm to ensure proper embedment into the bearing strata. Additional Fill and Utility Trenches This report discusses the fill placement observed by personnel from our firm during the periods specified. It is recommended that any additional fill placed, like those behind the Project No. 02-1167D2 Kachay Co. 12/09/03 Page 4 1 573 Rubenstein Avenue proposed on-site private road, as well as backfill placed in utility renches located within 5 feet of any improvements and deeper than 12 inches, or backfill placed in any trench located 5 feet or more from a building and deeper than 5 feet, be compacted under our observation and tested to verify compliance with the earthwork specifications for the project. Surface Drainage Proper control of the site drainage and regular maintenance of all drainage facilities are important factors related to the overall stability of the soil mass. No surface water should be allowed to collect and/or pond on the building pad, and the runoff should be directed to flow into the street gutter or other suitable on-site drainage facilities without intermediate ponding. Scheduling Earthwork Observations and Testing Services It is our intent to provide prompt, efficient and effective earthwork and testing services. To provide such services, the cooperation of our client is requested. Please provide us with lead time regarding the need for our field services of at least 48 hours whenever possible. We may not be able to fill requests for services made later than 4 p.m. of the previous evening. LIMITATIONS The soil conditions described in this report are based on observations and periodic testing. This office should be notified of any indications that soil conditions are not as described herein. The conclusions and opinions drawn from the test results and site observations apply only to our work with respect to the grading of subject property as shown on the approved grading plan. We will accept no responsibility for any subsequent changes made to this site by others, or by uncontrolled action of water, or by failure of others to properly repair damages by uncontrolled action of water. We cannot provide advice, opinions or conclusions relative to site preparation (clearing, grubbing etc.) which we have not observed. Professional judgments represented in this report are based partly on our evaluations of the technical information gathered, partly on our understanding of the proposed construction, and partly on our general experience in the geotechnical field. Our engineering work and judgments rendered meet or exceed the standard of care of our profession at this time. We do not guarantee the performance of the project in any respect.

Our study consisted of reviewing the proposed 5 lot design for the property, review Major Use Permits and analysis of the County of San Diego 200 scale ortho maps of the area, review of the site Specific Plans Rezoning soil classification map, review and analysis of the specific site aerial topography, review of Variances improvement and grading plans and drainage study for City of Encinitas Tract 89-229, and Administrative Permits a site field inspection. Annexations Boundary Adjustments The purpose of this investigation was to determine the adequacy of the proposed LAND SURVEYING improvements,to determine the increase in storm runoff from the subject property as a result Properly Surveys of the proposed improvements, and to develop a detention system to maintain post- Topographical Surveys Construction Staking development runoff equal to pre-developed runoff. Records of Survey Legal Descriptions HYDROLOGY Subdivision Maps Easements Height Certifications Hydrologic calculations were performed for the onsite basins affecting the proposed Cadasu al Surveys improvements. Q t s were determined by the County of San Diego Rational Method and are Photogrammelric Surveys presented on the attached Hydrology Calculations worksheet. In accordance with the City of Encinitas standards, soil classification type D was used in the analysis. The on-site drainage calculations were performed using a conservative 5 minute time of concentration. The watershed is shown on the attached Hydrology Map. Hydraulic calculations were performed using Flowmaster software by Haestad Methods. (760)753-5525•Fax(760)943-8236 4407 Manchester Avenue•Suite 105•Encinitas,California 92024 CONCLUSIONS Based upon the above criteria, per the attached calculations, the proposed improvements will adequately carry the anticipated storm runoff. Based upon the above criteria the computed 100 year storm runoff from the site to Rubinstein Avenue will increase from 3.22 cfs to 4.52 cfs, an increase of 1.30 cfs. The installation of a 2000 gallon underground detention tank will provide an attenuation of 1.3 cfs. This will maintain post- development runoff at the current pre-developed level. Based upon our review of the Grading plan 5293-G and Improvement plans and Drainage Study for City of Encinitas Tract 89-229 the existing concrete brow ditch along the South side of lot 26 and the west sides of lots 26 and 25 and the private storm drain between lots 25 and 24 (of map 14006) are designed to receive offsite drainage from the west. Our review indicates that the off-site areas included in the Tract 89-229 drainage study were"generous"and the actual flows from our proposed subdivision will be consistent or less than those anticipated by the Tract 89-229 design. We have attached portions of the hydrology maps and hydraulic calculations from the Tract 89-229 Drainage study as well as a portion of grading plan 5293-G sheet 3 of 9 for reference.

The study develops 100-year storm flows(Qloo) at critical points ghout the project site. The points include four drainage crossings under proposed street ents with Qioo flows emanating from eight onsite and five offsite tributary areas. All routed though the site have direct confluence with the existing natural channel bisecting site. In addition, calculations and typical details are included for design of culverts, rip rap, a inlets, catch basins,curb outlets, underdrains, and drainage ditches.

Based upon the above criteria the computed 100 year storm runoff from the site to Rubinstein Avenue will increase from 3.22 cfs to 4.52 cfs, an increase of 1.30 cfs. The installation of a 2000 gallon underground detention tank will provide an attenuation of 1.3 cfs. This will maintain post- development runoff at the current pre-developed level. Based upon our review of the Grading and Improvement plans and Drainage Study for Cardiff Glen, City of Encinitas Tract 89-224 the existing concrete brow ditch along the South side of lot 26 and the west sides of lots 26 and 25 and the private storm drain between lots 25 and 24 are designed to receive offsite drainage from the west. Our review indicates that the off-site areas included in the Cardiff Glen drainage study were "generous" and the actual flows from our proposed subdivision will be consistent or less than those anticipated by the Cardiff Glen design. We have attached portions of the hydrology maps and hydraulic calculations from the Cardiff Glen Drainage study as well as a portion of grading plan sheet 3 of 9 for reference. Our project indicates drainage from lots 3, 4 and 5 into the Cardiff Glen drainage structures consistent with the intent and design of the Cardiff Glen project and maintains existing runoff patterns and conditions without increase in flows.

October 25, 2002 GEOTECHNICAL INVESTIGATION INTRODUCTION - `presents the findings and conclusions of a geotechnical investigation This report conducted at the site of a proposed residential subdivision, located at 157') Rubenstein Avenue, in the City of Encinitas, State of California. Subject property is more specifically referred to as being Assessor's Parcel Nos. 280-084-10 and 11, in the City of Encinitas, State of California. The location of the property is shown on Figure No. 1, entitled, "Site Location Map". DESCRIPTION OF PROJECT - - It is our understanding that subject property is to be subdivided into 5 residential lots. The existing residence on the site will be demolished to accommodate the proposed development. The proposed residences to be constructed on these lots will be two stories in maximum height; ofwoodframe/stucco and sab-on-grade construction. Project No. 02-1167D2 Kachay Homes, Inc. 10/25/02 Page 2 Rubenstein Avenue ® SCOPE OF WORK - ---------- The objectives of the investigation were to inspect and determine the subsurface soil conditions and certain physical, engineering properties of the soils beneath the site, and to evaluate any potential adverse geotechnical conditions that could affect the proposed project, in order that engineering recommendations could be presented relative to the safe and economical development of the site as presently proposed. In order to accomplish these objectives, a total of six exploratory trenches were excavated and inspected, and representative samples of the subsurface soils were collected for laboratory testing and analysis. The data derived from our field observations and the laboratory test results were reviewed and analyzed, and a summary of our preliminary findings, opinions and recommendations is presented in this report. FIELD INVESTIGATION - - - - "The field exploratory phase of our investigation was performed on October 16, 2002, and involved the excavation of six exploratory trenches at locations as determined by our field personnel. These exploratory trenches were excavated with a tractor- -- mounted backhoe equipped with a 24-inch bucket.. These trenches were excavated to depths varying from 6.0 to 10.0 feet below existing ground surface. The approximate location of the exploratory trenches is shown on Figure No. 2, entitled, "Approximate Project No. 02-1167D2 Kachay Homes, Inc. 10/25/02 Page 3 Rubenstein Avenue Location of Exploratory Trenches". The trenching operation was performed under the direction of our field personnel, and a continuous log of the soil types encountered in the trenches was recorded at the time of excavation, and is shown on Figure Nos. 3 to 8, inclusive, each entitled, "Trench Log Sheet". The soils were visually and texturally classified by the field identification procedures set forth on the Unified Soil Classification Chart. In-situ density tests and representative samples were obtained at various depths in the exploratory trenches. LABORATORY TESTS ---------------------- --------- The samples collected during our field investigation were subjected to various tests in the laboratory to evaluate their engineering characteristics. The tests were performed in accordance with current A.S.T.M. testing standards or other regulatory agency testing procedures. A summary of the tests that were performed and the final test results are presented in Appendix II hereto. The tests that were performed included determinations of the maximum dry densities and optimum moisture contents, as well as the expansion indices of the soils encountered. Project No. 02-1167D2 Kachay Homes, Inc. 10/25/02 Page 4 Rubenstein Avenue SITE DESCRIPTION - - Subject property is an "L"- shaped property consisting of 1.09 acres, located on the east side of Rubenstein Avenue, north of Rubenstein Drive. From Rubenstein Avenue, the existing ground ascends in an easterly direction at gradients on the order of 8 to 10 percent. An existing single-family residence with detached carport was located in the rear, easterly portion of the site. This residence will be demolished to accommodate the proposed development. Beyond the east property line, a 25-foot high cut slope was observed, descending onto the residential development to the east. The property is bounded on the north, east and south by single-family residences; and on the west by Rubenstein Avenue. GENERAL GEOLOGY AND SUBSURFACE SOIL CONDITIONS --------------- --------------- -------- ------------------ -------- ------------ Geologic Setting and Soil Description ----------- --------- ---- ----- --------------- According to the Geology Map of the San Diego Metropolitan Area published by the California Division of Mines and Geology, the site is underlain by Quaternary-age terrace deposits. These terrace deposits were encountered on the site in the form - of reddish brown silty fine sands, which are very dense and cemented. Refusal in these dense formational material were encountered in all trench locations at depths varying from 6.0 to 10.0 feet below existing ground surface. The formation soils were overlain by a layer of residual soils on the order of 1 to Project No. 02-1167D2 Kachay Homes, Inc. 10/25/02 Page 5 Rubenstein Avenue 6 feet in thickness. These residual soils consist of light brown silty sands, the upper portions of which are dry and loose. Tectonic Setting ----------- --------- No evidence of faulting was noted during our surface reconnaissance or in the exploratory trenches. A review of available geologic literature did not reveal any major faulting in the area. It should be noted that much of Southern California, including the City of San Diego area, is characterized by a series of Quaternary-age fault zones which _ typically strike in a northerly to northwesterly direction. Some of these fault zones (and the individual faults within the zone) are classified as active while others are classified as only potentially active according to the criteria of the California Division of Mines and Geology. A review of available geologic maps indicate that the subject property is approximately 45.4 km (28.4 miles) southwest of the active Elsinore Fault Zone (Type A Fault), and approximately 4.1 km (2.6 miles) northeast of the active Rose Canyon Fault Zone (Type B Fault). GEOLOGIC HAZARDS ----------------- ----- ---------- Groundshaking- The most likely geologic hazard to affect the site is groundshaking as ------------------ a result of movement along one of the active fault zones mentioned above. Construction in accordance with the minimum standards of the Uniform Building Code and Project No. 02-1167132 Kachay Homes, Inc. 10/25/02 Page 6 Rubenstein Avenue requirements of the governing jurisdiction should minimize potential structural damage due to seismic activity. Seismic soil coefficient in accordance with the current Uniform Building Code were determined with the UBCSEIS Program and presented herein. Liquefaction Potential— In consideration of the competent natural soils underlying the ----------------- ----------- site, and the lack of a permanent groundwater table near the ground surface, it is our opinion that soil liquefaction does not present a significant geotechnical hazard to the proposed site development. Landslides - Subject property is located on gently sloping terrain and underlain by -------------- competent natural soils. A review of available geologic maps did not reveal any ancient landslides in the vicinity. An inspection of subject and surrounding properties did not reveal any indications of land movement. Therefore, the potential for landslide on subject or adjacent properties is considered negligible. Other potential geologic hazards such as tsunamis and seiches should also be considered negligible or nonexistent. GROUNDWATER ------------------------- No groundwater was encountered in the exploratory trenches to the maximum depth of exploration at 10.0 feet. No seeps or springs were observed on the site during our investigation. Project No. 02-1167D2 Kachay Homes, Inc. 10/25/02 Page 7 Rubenstein Avenue -- FINDINGS, CONCLUSIONS AND RECOMMENDATIONS ---------------- --------------------- ------- -------------------------------- General l. No adverse soil conditions were encountered which would prohibit the currently proposed development of the project site. 2. All of the soils encountered on the site are suitable for use as supporting materials for the proposed structures, provided that the recommendations contained herein are followed. 3. Some of the soils encountered on the site possess low expansion potential (Expansion Index= 38). Grading 4. It is recommended that all earthwork be accomplished in accordance with the Grading Ordinance of the City of Encinitas, UBC Chapter A33, Appendix I attached hereto, entitled, "General Grading and Earthwork Specifications", and recommendations as presented in this Section. -- 5. Where the recommendations of this Section of the report conflict with those of Appendix I, this Section of the Report takes precedence. 6. Grading operation should commence with demolition of the existing improvements on the site and disposal of all debris offsite. Project No. 02-1167132 Kachay Homes, Inc. 10/25/02 Page 8 Rubenstein Avenue 7. A keyway should be excavated into competent natural soils along the toe of the proposed fill slopes Any loose topsoils that remain below finished grade should be removed. The on site fill soils should then be properly moistened and uniformly compacted. All fill soils should be properly moistened, and uniformly compacted until proposed grade elevations are reached. The layers of fill should not exceed 8 inches to allow for adequate bonding. All fill soils should be compacted to at least 90 percent of maximum dry density in accordance with A.S.T.M. D1557. 8. In order to provide uniform settlement characteristics, it is recommended that the natural soils on the building pad be over-excavated to a depth of 3 feet, and uniformly recompacted to at least 90 percent of maximum dry density. 9. Imported fill soils may be required for the development of the project. It is recommended that these fill soils possess low expansion potential (Expansion Index < 50), and should be approved by our firm at the borrow site prior to importation. Foundation and Slab Design -------------- ---- ----- ----------- 10. A safe allowable soil bearing value of 1,800 pounds per square foot may be used in the design and checking of continuous or spread foundations that are a minimum of 12 and 24 inches in minimum horizontal dimension, respectively, Project No. 02-1167D2 Kachay Homes, Inc. 10/25/02 Page 9 Rubenstein Avenue and are embedded at least 12 inches (for single-family) or 18 inches (for two stories) into the competent natural or compacted fill soils. 11. The above safe allowable soil bearing value may be increased 300 pounds per square foot for each additional foot of depth or width, to a maximum of 3,000 pounds per square foot. 12. The above safe allowable soil bearing value may be further increased by one third when considering wind and/or seismic forces. 13. The settlement of foundations, when designed and loaded as outlined above, is within acceptable tolerance limits for residential structures of this type. 14. It is recommended that all continuous footings be reinforced with 2 #5 rebars; one rebar located near the top, and the other rebar near the bottom of the footings. Isolated pier footings should be reinforced with a minimum of 2 #5 rebars, in both directions, placed at mid-height of footing.. 15. The concrete slab on grade should be 4 inches net in thickness, and reinforced with#3 rebars @ 24 inches on center in both directions, placed at mid-height of slab. The concrete slab should be underlain by 4 inches of clean sand. In areas to be tiled or carpeted, a visqueen-type moisture barrier should be placed at grade and be overlain by one inch of protective sand cover. This moisture barrier should be heavily overlapped or sealed at splices. Project No. 02-1167D2 Kachay Homes, Inc. 10/25/02 Page 10 Rubenstein Avenue Please note that the foundation and slab reinforcement requirements are based on soil characteristics, and should be superceded by the requirements of the project architect.. 16. The settlement of foundations, when designed and loaded as outlined above, are within acceptable tolerance limits for light residential buildings of this type. 17. It is recommended that our firm inspect the foundation trench excavations for the proposed structures to ensure proper embedment into properly compacted fill soils. 18. It is recommended that foundation for the proposed structures be setback at least 7 feet from the top of slope. Foundations placed closer to the top of slope than 7 feet should be deepened such that the outer edge of the foundation along the bottom is at least 7 feet back from the face of slope at that level. Retaining Wall Design and Lateral Loads ----------------------- ---------------------------- ---------- 19. Retaining wall foundations should conform to the recommendations under Item Nos. 10 to 18 above. 20. Active earth pressures against retaining walls will depend upon the slope of the backfill and the degree of wall restraint. Unrestrained retaining walls free to rotate at the top and with level backfill should be designed to resist an active earth pressure equivalent to that generated by fluid weights as shown below Project No. 02-1167132 Kachay Homes, Inc. 10/25/02 Page 11 Rubenstein Avenue Equivalent Backfill Slope Fluid Wt. (Horizontal : vertical) (Pcf) Level 35 2 : 1 48 1 '/2 : 1 56 For rigid, absolutely restrained retaining walls, an uniform horizontal pressure of 7H (where H is the height of the retaining wall in feet) should be applied in addition to the active pressure recommended above. 21. The above active earth pressures are provided assuming that soils having low expansion potential (Expansion Index < 50) are placed behind the retaining walls. All backfill soils should be compacted to at least 90 percent of maximum dry density. 22. To resist lateral loads, it is recommended that the pressure exerted by an equivalent fluid weight of 280 pcf be used for footings or shear keys poured neat against competent undisturbed natural soils. The upper 12 inches of material in areas not protected by floor slabs or pavement should not be included in the design for passive resistance. This value assumes that the horizontal distance of the soil mass extends at least 10 feet or three times the height of the surface generating the passive pressure, whichever is greater. 23. A coefficient of friction between soil and concrete of 0.35 is recommended. Project No. 02-1167132 Kachay Homes, Inc. 10/25/02 Page 12 Rubenstein Avenue 24. Retaining walls should be properly waterproofed and provided with gravel and perforated pipe drain systems to reduce the potential for hydrostatic pressure buildup behind the retaining walls. The gravel portion of the drain should extend at least two-third the height of the retaining wall and should be enclosed in a filter fabric envelope. 25. The on-site soil conditions are such that standard cantilever retaining wall designs, such as those presented in the San Diego Regional Standard Drawings or those issued by the City of Encinitas Building Department, may be used, where appropriate. Slope Stability ------- ----------- 26. Minor cut and fill slopes under 15 feet in maximum height are proposed for the development of the site. It is our conclusion that both cut and fill slopes will be safe against massive slope failure up to the proposed heights when constructed at a slope ratio of 2 : 1 (horizontal : vertical) or flatter. 27. The above conclusions assume that surface water is not permitted to flow over the top of slopes, and that all slopes are properly planted and irrigated in accordance with the requirements of the City of Encinitas. Seismic Soil Coefficients ------------------------------------ 28. Seismic soil coefficients were determined in accordance with the Uniform Project No. 02-1167D2 Kachay Homes, Inc. 10/25/02 Page 13 Rubenstein Avenue — Building Code, and presented as follows Parameters Value Reference Seismic Zone Factor 4, Z 0.40 Table 16-I -` Soil Profile Type Sc Table 16-J Near Source Factor,Na 1.1 Table 16-5 Near Source Factor,Nv 1.3 Table 16-T Seismic Coefficient, Ca 0.44 Table 16-Q Seismic Coefficient, Cv 0.74 Table 16-R Seismic Source Type B Backfill Over Utility Trenches ---------- ------ -------- ------------ 29 It is recommended that backfill soils placed in utility trenches located within 5 feet of any improvements and deeper than 12 inches, or backfill placed in any trench located 5 feet or more from a building and deeper than 5 feet, be compacted under our observation to at lest 90 percent of maximum dry density. Private Road Pavement Section ---------- ------- ------------ --------- 30 The PCC private road serving the subdivision should be 5 '/2 inches net in thickness, and be reinforced with 6x6-W2.9xW2.9 (6x6-6x6) welded wire fabric, placed at mid-height of concrete slab. Control joints at a minimum of 10-foot intervals should be provided. 31. The upper 8 inches of the subgrade soils should be compacted to at least 95 percent of maximum dry density. Project No. 02-1167D2 Kachay Homes, Inc. 10/25/02 Page 14 Rubenstein Avenue 32. if a flexural structural pavement is proposed for the private road, it is recommended that a preliminary structural section of 3 inches of asphaltic concrete over 4 inches of Class I1 base material be used for design purposes. The upper 8 inches of the subgrade and base material should be compacted to at least 95 percent of maximum dry density. 33. It is further recommended that the actual flexural pavement section design be used on actual "R"-value tests performed on the subgrade soils upon completion of rough grading. Concrete Flatwork ------------ ----------- 34. It is recommended that all concrete flatwork, such as walkways, be 3 `/2 inches in Thickness. Four inches of sand or rock base material should be provided. One inch expansion joints at 15-foot intervals and '/4 inch weakened plane contractor joints at 5-foot intervals should also be provided. Surface Drainage and Maintenance --------- ----------- ----- ------------------ 35. Adequate drainage control and proper maintenance of all drainage facilities are imperative to minimize infiltration of surface water into the underlying soil mass in order to reduce settlement potential and to minimize erosion. The building areas should have drainage swales which direct storm and excess irrigation water away from the structures and into the street gutters or other drainage facilities. No surface runoff should be allowed to pond adjacent to the foundations. Project No. 02-1167132 Kachay Homes, Inc. 10/25/02 Page 15 Rubenstein Avenue Grading and Foundation Plans Review --------------- ------ ---------- ------- -------- 36. It is recommended that our firm review the final grading and foundation plans for the proposed site development to verify their compliance with the Uniform Building Code, Chapter A33, as required by the State of California.
