November 25, 2009 RC Construction Co. 3080 Madison Street Carlsbad, CA. 92008 Subject : Project No. 08- 1147B6 Report of Compacted Filled Ground Proposed Residential Building Site 221 Florita Street Encinitas, California Gentlemen: This report records our observations of the grading and the results of tests performed in connection with our inspection of the compaction of fill soils placed on certain areas of the proposed residential building site on subject property, more specifically referred to as being Lot 13, in Block D, of North Encinitas, according to Map thereof No. 1845 (Assessor's Parcel No 256- 373- 16 -00), in the City of Encinitas, State of California. The grading reported herein was accomplished during the period from November 16 to 23, 2009, inclusive. Prior to commencement of grading, the existing residential structure and other improvements on the site were removed, and the debris hauled away and disposed of offsite. Existing soils loosened by the demolition process within a minimum distance of 5 feet outside the foundation line of the proposed residence were removed. Maximum depth of removal was on the order of 4 feet. The removed soils were properly moistened, and replaced and uniformly recompacted until finished grade is achieved. The in -situ densities of the soils placed were tested in accordance with the applicable provisions of ASTM D2922. The depths of fill at which the tests were taken and the final test results are presented on page T -1, 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 shown on Figure No. 1, Project No. 08- 1147136 RC Construction Co. 11/25/09 Page 2 221 Florita Street entitled, "Approximate Location of Compacted Filled Ground The results of the tests and observations indicate that the fill soils placed on the site have been compacted to at least 90 percent of maximum dry density at near optimum moisture content. Test results indicate that the building pad is adequate for its intended use as support to the proposed residential building. The soils encountered on the site possess low expansion potential (Expansion Index = 38). It is recommended that a safe allowable soil bearing value of 2,000 pounds per square foot be used in the design and checking of continuous footings that are a minimum of 12 inches in minimum horizontal dimension, and interior spread footings that are a minimum of 24 inches in minimum horizontal dimension, and are embedded at least 12 inches (for single story) or 18 inches (for two stories) below the surface of the competent natural or compacted fill ground. It is recommended that all continuous footings be reinforced with four #5 rebars; two rebars located near the top, and the other two rebars near the bottom of the footings. Isolated pier footings should be reinforced with a minimum of 2 #5 rebars in each direction, placed near the bottom of the footing. The concrete slab -on -grade should be 4 inches net in thickness, and be reinforced with #3 rebars @ 18 inches on center, placed at mid- height of concrete slab. The concrete slab should be underlain by 4 inches of clean sand. In areas to be tiled or carpeted, a10 -mil 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. Please note that the above foundation and slab reinforcement recommendations are based on soil characteristics, and should be superceded by the requirements of the project architect or structural engineer. 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. Surface water around the perimeter of the proposed structure should flow away from the structure at a gradient of 2 percent for a minimum distance of 5 feet, and drain into the street or into on -site drainage structures without intermediate ponding. This report discusses the fill placement observed by personnel from our firm during the periods specified. It is recommended that any additional grading and/or fill soils placed, like backfill soils behind retaining walls, as well as backfill placed in utility trenches 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 Project No. 08- 1147136 RC Construction Co. 11/25/09 Page 3 221 Florita Street our observation and tested to verify compliance with earthwork specifications of the project.

November 28, 2008 SOIL INVESTIGATON This report presents the findings and conclusions of a soil investigation conducted at the site of a proposed residence on subject property, located at 221 F(orita Street, in the City of Encinitas, State of California. Subject property is more specifically referred to as being Lot 13� in Block D, of North Encinitas, according to Map thereof No. 1845 (Assessor's Parcel No 256- 373 -16- 00). The location of the property is shown on Figure No. 1, entitled, i'Site Location Map ". DESCRIPTION OF PROJECT It is our understanding that the existing residential structure on the site is to be demolished to accommodate a new single - family residence. The proposed structure will be two stories in height; of woodframe /stucco and slab -on -grade construction. SCOPE OF WORK The objectives of the investigation were to inspect and determine the subsurface geotechnical conditions and certain physical engineering properties of the soils beneath Project No. 08- 1147136 Chilingirian 11/28/08 Page 2 221 Florita Street 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; and checking and design of foundation for the proposed structure. In order to accomplish these objectives, a total of three exploratory borings were excavated and inspected, and representative samples of the subsurface Soils were collected for laboratory testing and analysis. The data derived from the field observations and laboratory test iresults 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 November 19, 2008, and involved a reconnaissance of the site, and the excavation of three exploratory borings with a portable bucket auger. The exploratory borings were excavated at various locations on the site where the most useful information relative to subsurface soil conditions may be obtained. The exploratory borings were excavated to depths varying from 6 to 8 below existing ground surface. The location of the exploratory borings was recorded at the time of excavation, and is shown on Figure Nos. 3 to 5, inclusive, each entitled, `Boring Log Sheet ". Project No. 08- 1147136 Chilingirian 11/28/08 Page 3 221 Florita Street The soils were visually and texturally classified by the field identification procedures set forth on the Unified Soil Classification Chart. Representative samples were obtained, and the in -situ densities of the soils encountered were obtained at various depths with a Triggs penetrometer. LABORATORY TESTS The samples collected during our field investigation were subjected to various tests in the laboratory to evaluate their engineering characteristics. Thd tests were performed in accordance with current A.S.T.M. testing standards or otl}er regulatory agency testing procedures. A summary of the tests that were performed and the final test results are presented in Appendix 11 hereto. The tests that were performed included determinations of the maximum dry densities and optimum moisture contents; the sulfate contents and Expansion Indices of the soils encountered. SITE DESCRIPTION I Subject property is a rectangular- shaped property of 3,672 squats feet, situated on the south side of Florita Street, approximately 150 feet west of the intersection with La Veta Avenue. The topography of the general area may be described as relatively level, with surface drainage in a southwesterly direction. A single -story residence currently occupies the site. Based on available public records, it is our understanding that this structure, consisting of 1,088 square feet, was constructed in 1947. Project No. 08-1147136 Chilingirian 11/28/08 Page 4 221 Florita Street The general area is fully developed; with the property bounded on the east, west and south by existing residences; and on the north by Florita Street. GENERAL GEOLOGY AND SUBSURFACE SOIL CONDITIONS Regional Geolot3y The subject property is located within the southern coastal strip region of the Peninsular Range Geomorphic Province of California. This geomorphic province is characterized by mountainous terrain to the east composed mostly of Mesozoic igneous and metamorphic rocks and relatively low -lying coastal terraces to the }west underlain by late Cretaceous, Tertiary and Quaternary sedimentary rocks. The City of Encinitas, including the site, occurs within the westerly region and is underlain by Quaternary sedimentary rocks. Site Geoloav and Subsurface Soil Conditions A review of geologic map of the Encinitas Quadrangle published by the California Division of Mines and Geology, as well as observations made during our subsurface exploration indicated that the general area is underlain by Quaternary-age Terrace Deposits. On subject property, these Terrace Deposits were encountered in the form of medium dense to dense, brown silty sands. The Terrace Deposits were overlain by approximately 12 to 18 inches of residual soils, consisting of loose to slightly dense, brown silty sands, with abundant root matters. Project No. 08- 1147136 Chilingirian 11/28/08 Page 5 221 Florita Street Tectonic Settine No evidence of faulting was noted during our surface reconnaissance or in our exploratory borings. 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 Encinitas, 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 othets are classified as only potentially active according to the criteria of the California Divisidn of Mines and Geology. A review of available geologic maps indicate that the subject property is approximately 14.2 km (8.9 miles) from the Rose Canyon Fault zone (Type B Fault), and 44.9 km (28.1 miles) from the Elsinore -Julian Fault zone (Type A Fault). GROUNDWATER No groundwater was encountered in the exploratory borings to the maximum depth of exploration at 8 feet, and no major groundwater related problems, either during or after construction, are anticipated. However, it should be recognized that minor seepage problems may occur after development of a site even where none were present before development. These are usually minor phenomena and are often the results of an alteration of the permeability characteristics of the soils; an alteration in drainage patterns due to grading; and an increase in the use of irrigation water. Based on the permeability characteristics of the soils and anticipated usage of the development, it is our opinion that Project No. 08- 1147136 Chilingirian 11/28/08 Page 6 221 Florita Street any seepage problems which may occur will be minor in extent. It is further our opinion that these problems can be most effectively corrected on an individual basis if and when they develop. GEOLOGIC HAZARDS Ground shakine — The most likely geologic hazard to affect the site is ground shaking as a result of movement along one of the active fault zones mentioned above. For seismic design purposes, soil parameters in accordance with the 2007 edition of the California Building Code were determined, and presented hereinafter Liquefaction Potential - In consideration of the competent formational soils underlying the site, and the lack of a permanent water 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 relatively level terrain, and underlain by competent formational soils.. A review of available geologic maps did not reveal the presence of any ancient landslides on subject or adjacent properties. The potential for landslides on subject and adjacent properties is considered minimal. FINDINGS, CONCLUSIONS AND RECOMMENDATIONS General I . Based on the results of the investigation, it is our opinion that the currently proposed site development is feasible from a geotechnical engineering standpoint, Project No. 08- 1147136 Chilingirian 11/28/08 Page 7 221 Florita Street provided that the recommendations presented in this report are incorporated into the design plan(s) and are properly implemented during the construction phase. 2. It is noted that some of these recommendations may have to be modified and supplementation recommendations may have to be presented, d #pending on the actual subsurface conditions encountered during construction. No adverse geotechnical conditions were encountered which wquld prohibit the currently proposed development of the project site. All of the sails encountered are suitable for use as supporting materials for the proposed structures and improvements, provided that the recommendations contained herein are followed. Expansion Index of On -Site Soils 4. The soils encountered on the site possess low expansion potential (Expansion Index = 38). Sulfate Content of On -Site Soils 5. The soils encountered on the site are subject to negligible sulfate exposure (sulfate content of 71 ppm). Gradwe 6. It is recommended that all earthwork be accomplished in accordance with the Grading Ordinance of the City of Encinitas, 2007 edition of the Califomia Building Code, Appendix 1 attached hereto, entitled, "General Grading and Earthwork Specifications ", and recommendations as presented in this Section. Project No. 08- 1147136 Chilingirian 11/28/08 Page 8 221 Morita Street Where the recommendations of this Section of the report conflict with those of Appendix I, this Section of the report takes precedence. 8. Grading operations should begin with the demolition of the existing structures and other improvements, and clearing and grubbing of the site. All debris and vegetation should be hauled away and disposed of offsite at an approved dump site. The upper soils will be disturbed and loosened by the demolition process. Furthermore, the upper residual soils were found to be loose and compressible. It is recommended that the existing upper soils to a depth of 3 feet within 5 feet outside the foundation line of the proposed residence be removed. 10. The bottom of the excavation should be inspected and verified by our firm, and scarified to a depth of 8 inches. The removed soils should then be properly moistened, and uniformly recompacted in layers not to exceed 81nches until finished grade is achieved. 11. All fill soils should be compacted to at least 90 percent of maximum dry density at near optimum moisture content, in accordance with A.S.T.M. D1557. Foundation and Slab Design 12. It is recommended that a safe allowable soil bearing value of 2,000 pounds per square foot be used for the design and checking of continuous footings that are 12 Project No. 08- 1147B6 Chilingirian 11/28/08 Page 9 221 Florita Street 13 14 I5. 16. inches in minimum horizontal dimension, and isolated pier footings that are 15 inches in minimum horizontal dimension; and are embedded at least 12 inches (for single story) or 18 inches (for two stories) below the lowest adjacent ground surface. The above safe allowable soil bearing value may be increased by one -third when considering wind and/or seismic forces. The settlement of foundations, when designed and loaded as outlined above, is within acceptable tolerance limits for light residential buildings of this type. It is recommended that all continuous footings be reinforced with a minimum of 4 #5 rebars; two rebars located near the top, and the other two rebars near the bottom of the footings. All isolated pier footings should be reinforced with a minimum of 2 #5 rebars in both directions, pleased near the bottom of the footings. The concrete slab -on -grade should be 4 inches in thickness, and be reinforced with #3 rebars @ 18 inches on center in both directions, placed at mid - height of concrete slab. The concrete slab should be underlain by 4 inches of clean sand. The above foundation and slab reinforcement requirements are based on soil characteristics, and should be superceded by the requirements of the project architect. Project No. 08-1147136 Chilingirian 11/28/08 Page 10 221 Florita Street 17. It is recommended that our firm inspect the foundation trench eitcavations for the proposed structure to ensure proper embedment into competent natural or compacted fill soils. Retainin¢ Wall Desitan 18. It is recommended that retaining walls be designed to withstandsthe pressure exerted by equivalent fluid weights given below: Equivalent, Backfill Fluid Surface Pressure (horizontal : vertical) (pcf) Level 35 2 : 1 50 1' /x:1 58 The above values assume that the retaining walls are unrestrained from movement, and have a granular backfill. For retaining walls restrained from movement at the top, such as basement retaining walls, an unifotm horizontal pressure of 7H (where H is the height of the retaining wall in feet) should be applied in addition to the active pressures recommended above. 19. All retaining walls should be supplied with a backfill drainage system adequate to prevent the buildup of hydrostatic pressure. The subdrain should consist of one - inch gravel and a perforated pipe near the bottom of the retaining wall. The width of this subdrain should be at least 12 inches, and extend at least �/3 height of the retaining wall. The subdrain should be enclosed in a geotextile fabric such as Project No. 08- 1147136 Chilingirian 11/28/08 Page 11 221 Florita Street Mirafi 140N or equal. Details of typical subdrains are shown on Figure No. 6 20. The on -site soil conditions are such that cantilever -type retaining walls similar to those presented in the Regional Standard Drawings or those issued by the City of San Diego Building Department may be used, where appropriate. Lateral Loading 21. To resist lateral loads, it is recommended that the pressure exerted by an 22 equivalent fluid weight of 250 pcf be used for footings or shear keys poured neat against competent natural or compacted fill soils. The upper 12 inches of material in areas not protected by floor slabs or pavements should not be ilncluded 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. A coefficient of sliding friction of 0.35 may be used for cast -in -place concrete on competent natural or compacted fill soils. Footings can be designed to resist lateral loads by using a combination of sliding friction and passive resistance. The coefficient of friction should be applied to dead load forces only. 23. All backfill soils behind the retaining wall should consist of soils having low expansion potential (Expansion Index < 50), and be compacted at least 90 percent of maximum dry density. Project No. 08- 1147B6 Chilingirian 11/28/08 Page 12 221 Florita Street Seismic Coefficients 24. The seismic design factors were determined in accordance with the 2007 California Building Code, and presented below: Site Coordinates : Latitude Longitude Site Class Site Coefficient Fa Site Coefficient Fv Spectral Response Acceleration At Short Periods Ss Spectral Response Acceleration At 1- second Period Sl Sms = FaSs Sml = FvSI Sds = 2/3 *Sms Shc = 2 /3 *Sml 33.05199 - 117.29805 D 1.00 1.50 1.405 0.527 1.405 0.791 0.937 0.527 Concrete Flatwork 25. In consideration of the on -site soil conditions, it is recommended that concrete flatwork be a minimum of 3 %x inches in thickness, and be reinforced with 6x6 - W 1.4xW 1.4 (6x6- 10 /10) welded wire fabric, placed at mid - height of concrete slab. One inch expansion joints should be provided at 15 -foot intervals, with '/4 inch weakened plane contraction joints at 5 -foot intervals. Driveway Pavement Desien 26. The proposed concrete driveway should be a minimum of 4 incites in thickness, and be reinforced with 6x6 -W 1.4xW 1.4 (6x6- 10 /10) welded wire fabric. The upper 8 inches of the subgrade soils should be compacted to at least 95 percent of maximum dry density. Project No. 08- 114786 Chilingirian 11/28/08 Page 13 221 Florita Street Surface Drainaee and Maintenance 27. 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 pad 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 foundation of structures. Grading and Foundation Plans Review 28.

INTRODUCTION AND PROJECT The purpose of this Drainage Study is to provide a 100 -year storm LOCATION investigation and analysis of the drainage area tributary to this project development and to recommend drainage data for the development's engineering design and construction. • Introduction This Drainage Study will address the hydrologic and hydraulics issues and features of the Joyce Chilingirian Family Residential Project, as follows: 1) The hydrology of the project area, which essentially mean addressing watershed characteristics, precipitation and rainfall, and flood calculations; and 2) The application of hydrologic data to the design of drainage systems to protect this project development from a 100 -year flood regime. This Study will provide hydrologic and hydraulic data at design storm frequency of 100 -years consistent with current standards of the City of Encinitas. A step -by -step procedure of the technical rationale used, including calculations and derivations of technical data, will be developed and described in this Study. • Project Location and T000graohv This project is located in the incorporated City of Encinitas, State of California. The property is legally described as Lot 13, Block D, North Encinitas per Map 1845, APN 256- 373 -16. • Vicinity Mao The street address is at 221 Florita Street, Encinitas, California 92024. It is accessible from Interstate Freeway I -5 at Encinitas Blvd. westbound off -ramp for a distance of about three- fourths of a mile. The project site lies in a fully developed and older residential urban area at about 2 to 3 blocks east of the Pacific Ocean coastline. The general land configuration is relatively Flat with more distant areas of moderate to steep rolling terrain. The project property itself has an average grade of about 2 percent and generally drains towards its frontage street, Florita Street. There is an existing one -story wood - framed residential building in the property. The property boundaries along the east, west and south sides are fenced with existing masonry blocks and effectively hinder any storm flows from the adjacent neighbors from entering the property. The front yard is of impervious surfacing of bricks and cement concrete. There are significant amounts of tree landscaping in the neighborhood. A bird's eye view of the project site is shown in the vicinity map on the following page. Drainage Study J. Chilingirian Property 01.19.09 1 3 & 6 Engineers. Surveyors A bird's eve view of the project site is shown in the vicinity man hereunder. J. Chilingirian Property 01.19.09 2 ] & B Eng ineers. Surveyors ii. DEVELOPMENT PLAN AND SITE The proposed development of this property conforms with the CHARACTERISTICS zoning of the area, which is principally single - family residential land use. The land is relatively flat with an average grade of approximately 2 percent. The property has a gross area of about 0.08 acre or 3,579 square feet. • Development Plan The development plan for this project may briefly be described, as follows: 1) Prepare preliminary architectural and grading plans for project approval for construction of a Single - Family Residence in accordance with the land development criteria of the City of Encinitas. 2) Upon preliminary approval by the City of Encinitas, prepare the required planning and engineering development plans for processing of the final construction permits. • Site Characteristics The site characteristics for this project based on existing land use, soil group, imperviousness and runoff coefficient will not change materially, before or after project, as summarized in Table 1 below: Table 1. Site Characteristics Project Land Use Land Use % Impervious Soil Type Runoff Status (NRCS) (SDC) Element Coefficient Element Low Density Residential, 1.0 After Project Residential DU /A or less 48 B 0.60(2) Low Density Residential, 1.0 No Project Residential DU /A or less 10(') B 0.32(') (') Based on Table 3 -1, San Diego County Hydrology Manual, prior to existing improvements. (2) For modification of design runoff, CM, due to change in imperviousness, use the following equation: CM= 0.90x % imp +(1- % imp) CP Where: CM = Modified coefficient of runoff CP = Coefficient of runoff for pervious soil (From Table 3 -1) % imp = imperviousness factor, dimensionless ratio • Hydrologic Soil Classification Hydrologic soil groups are classified according to their capacity to absorb water and the percentage of storm water runoff resulting therefrom. As indicated in the foregoing Table 1 and in the Hydrologic Soils Group Map, Attachment 3, this project site belongs to Hydrologic Soil Group B. Drainage Study J. Chilingirian Property 01.19.09 3 3 & B Engineers.Surveyors iii. HYDROLOGY Unless otherwise noted, the primary technical references that will be used in this Study are the County of San Diego's Hydrology Manual of June 2003 and the Drainage Design Manual of July 2005. The drainage area tributary to this project development is small and falls within the watershed category of less than 1.0 square mile (approximately 640 acres); therefore, the methodology of computing the hydrology of this construction activity will be the Rational Method (RM), briefly described as follows: Q = CIA Where: Q is the peak rate of flow in cubic feet per second (cfs). C is a runoff coefficient expressed as that percentage of rainfall which produces the peak discharge. I is the rainfall intensity in inches per hour for storm durations of 6 and 24 hours appropriate for developing peak flood discharges for 100 -year storm. A is the drainage area in acres. • Runoff Coefficient, C The runoff coefficient ( C ) is essentially based on 3 components, i.e., soil type, land use and imperviousness. As shown in Table 1, the coefficient of runoff for this project has a modified value 0.60 due to increased imperviousness "after project." The rest of the components remain unchanged. • Time of Concentat_ion, Tc Since the drainage area of this project is marginally small and confined within property lines, the time of concentration for this project will be equivalent to the initial time (T, ) of the maximum overland flow for an initial area tabulated in Table 2 below.

Chilingirian Property 01.19.09 4 3 & 8 Engineers.Surveyors • Rainfall Intensity, I Calculation of rainfall intensity for a specific storm frequency can be determined by the use of the Intensity - Duration - Frequency Chart, Attachment 6. The rainfall precipitation amounts P6 and P24 ( 6 -hour and 24 -hour peak flow durations, respectively) are determined by the location of the project in isopluvial maps with contour lines representing rainfall gauge readings at various storm frequencies. Interpolating between contour lines shown in the County isopluvial maps to the approximate centroid of the site is an acceptable method and will be used in this Study. As recorded on isopluvial maps in Attachments 4 and 5, showing rates of precipitation for 100 -year storm events at 6- hr /24-hr time distribution, the corresponding rainfall precipitation rates for this drainage area are as follows: • P6 = 2.5" • P24 = 4.0" By use of the Intensity- Duration - Frequency curves which essentially integrate the time component in the equation, the above rainfall precipitation rates in inches are converted to rainfall intensities in inches per hour. See attachment 6, Intensity- Duration- Frequency Design Data. iv. DRAINAGE AREAS A field verification trip to the site was made on January 16, 2009 to verify actual land conditions in the field. Digital photos of the site are shown in Attachment 1. • Pre- Development As may be seen in the site photos, the project site and surrounding areas are fully developed with single family homes. The property itself is currently occupied by an existing residential house which will completely be demolished and replaced by a new 2 -story residential building. The existing imperviousness is identical to the proposed improvements. Consequently, hydrologic calculations for a pre - development condition will not be required. Site characteristics will remain essentially the same, including new impervious materials proposed in the the new development. • Post - Development The base map used in mapping the drainage area for this project at post- development condition is the preliminary grading plan, scale 1 " =10 feet. Post - development flows in this project are collected and conveyed principally by a combination of sheet and Swale flows. Drainage Study J. Chilingirian Property 01.19.09 5 3 & B Engineers.Surveyors As shown in the Drainage Map, post - development condition, the drainage area tributary to this project is only about 0.08 acre, which corresponds to the gross area of the property. The drainage area is divided into two initial areas with an average slope of about 2 percent. Tributary water basin data for this project at post- development condition for 100 -year storm frequency are shown in Table 3 below: Table 3.

The stormwater discharge from these two curb outlets flow along the gutter in a westerly direction along Florita Street. There are no existing underground storm drains in the immediate area of the project. The Pacific Ocean is obviously the final downstream destination of these stormwater discharges. For quantification of the 100 -year peak Flow in this project, please see the Drainage Map, post - development condition, and the Rational Method hydrologic calculation sheet in the following pages.

HYDRAULICS AND DRAINAGE The Preliminary Grading Plan proposed for this project is designed SYSTEM to perpetuate the existing drainage patterns in this drainage basin, and to convey onsite 100 -year peak flows safely to final discharge offsite. The proposed drainage system comprise mainly of swales that collect onsite sheet flows, and thence convey these flows to two existing sidewalk underdrain pipes along Florita Street. The aggregate 100 -year peak flow for this project is 0.20 cfs. Each of the existing underdrain will discharge 0.10 cfs to Florita Street, which is less than the underdrain capacity of 0.14 cfs. • Hydraulic Design Data Design calculations will be based on Manning's formula and other applicable equations from the San Diego County Design Manual of July 2005. • Grass Swale Calculations Grass swales perform a dual function of conveying storm flows, as well as the treatment of stormwater pollutants. The sizing of grass swales, however, will be based on 100 -year peak flow. Hydraulic calculations for the typical open channel flow (grass swales) will be based on the following design data: • Geometric Shape: Triangular, Top width =5 feet, Z= 3, • Assume max, water depth= 0.33 feet (4 ") Maximum capacity of the grass swale is calculated as follows Q= 1.486/0.013 x A x R2/3 x S1j2 Where: A = 0.33 sf R113 = 0.45 Sue = 0.141 (S =2.0 %) n = 0.035 (grass) By substitution: Q = 0.89 cfs > 0.10 cfs ok Velocity = 2.7 fps (maximum) • Existing Underdrain The existing underdrain corresponds to SDRSD. No. D -27 with a Capacity 3" pipe. Capacity of this drain is calculated as follows: Q= 1.486/0.013 x A x R213 x S3/2 Where: A = 0.049 sf R213 = 0.156 5112 = 0.158 (S =2.5 %) n = 0.013 (PVC pipe) By substitution: Q= 0.14cfis > 0.10 cfs ok Drainage Study J.

CONCLUSIONS The analysis of the drainage issues in this project has come to the following conclusions: 1) The development of this project area will not significantly affect the existing watershed conditions of this drainage basin. Drainage patterns will remain essentially the same, and the existing discharge points along Florita Street (2- underdrains) are adequate to safely convey the on -site peak flows to Florita Street. 2) No soil erosions or negative environmental impacts will result from this project. vii.
