The study covered by this report was .ade to determine the necessary, size for'<=\ desilting basin 'for the project. The basin is sized so that sediment runoff fr6m the project wi 11 not be increased by developement of the project. The project lies mainly in one natural dr.inage ba.in which will drain to the proposed desilting basin. The project is parti.lly located in another drainage basin, but comprises only three percent (3%) of the basin by area and will not increase sedim~nt yield appreciably. -tiJETHODOLOGY - The Army Corps of Engineers H.E.C. 1 and S.T.O.R~M. co~puter programs were employed in the design of the Laguna Riviera des~lting basin. ," The H.E.C. 1 program is a flood hydr'ograph pro:gramwhose i~puts include basin area, infiltrat.ion p,otential and basin lag ;:", , " time. The program is used to determine peak flow dis~harge. for ~,~~ different frequency storm floods. The 10 year peak di_charge was used in the sizing of the basin using ~ capacity versus inflow relationship. The 100 year peak discharge I'las used in thetle.si'gn of the outflow works from the basin to assure that the b~sin ~~11 riot be overtopped in the event of a 100 year storm. The S.T.O.R.t"!. program is u'sed to c·ompute sediment yield for a given area. It's inputs include soil types, 'e""'rpdibil,ities" -1- I I areas, slope gradients and rainfall data. -DESIGN CONSIDERATIONS- The basin is designed to have a trap effici~ncy of 95X+for a year with a total annual precipitation that is only expected tp be e>:ceeded 107. of the time. The trap efficiency increases for the higher probability annual rainfalls and decreases for the lower probability years. The basin is also designed to pass the 100 year peak discharge without overtopping. -REf;jULTS- Sediment yields were computed for both pre and post~ developement condi ti ons. Post-developement referi ng to the 1,8_ to 24 mohth construction period, this being the perio!=! of ma>:imum potenti al sedi ment yi el d. Before and after condi t,i ons were both calculated in order to be sure that sediment oLl1;:flow from the prOject is not increased due to the developement of the property. In an average precipitation year t~e basin ~an be expected to trap approximately 76 tons of sediment. 981. the total sediment yield of the basin. In a 10% probability rai nfall year the amount wi 11 be appro>: i matel y 234 tons. The 100 year frequency storm discharge to be passed by the basin ,outlet works is 29 c.f.s. The basin should be maintained on an annual basis~ The maintenance should inclLtde, but not necesssarilY be limited to, -2- .:. ,".: .:.'~ ~. '.

Sukup FINAL REPORT OF ENGINEERING OBSERVATION OF GRADING AND TESTING OF COMPACTED FILL RECREATION PAD PHASE 1 AND RECREA TION PAD PHASE 2 LOTS 1 THROUGH 35 PHASE 2 LOTS 9 THROUGH 20 PHASE 3 LAGUNA DEL MAR CARLSBAD, CALIFORNIA Gentlemen: .'$ wJs , , . In accordance with your request and our proposal dated January 9, 1985 we are providing engineering services in conjunction with the regrading of the subject site. ." SCOPE OF WORK Our services include: o o o Providing engineering observation of the grading operation; Performing field density tests in the pl~ced and compacted fill; Performing laboratory tests on representative samples of the material used for fill; '- SUMMARY OF GENERAL EARTHWORK AND TESTING Current site preparation, compaction, and testing were done between July 11, and ,October 10, 1985. In our opinion, based on our observation and Consultrng Engineers, Geologists and EnVironmental Scientists Offices In Other Principal Cities Native Sun Develo.ent Project No. 51101B-FC01 November 1, 1985 Page 2 • Woodward· Clyde Consultants testing, the work performed during that period was in general conformance with the Guide Specifications -for Site Grading attached to our report entitled "Update Geotechnical Investigation Laguna Del Mar, Carlsbad Tract 82-6, Carlsbad, California," dated February 25, 1985. Previous grading of the subject site was completed in January 1972 and September 1981. That grading work is summarized in the above report. It essentially consisted of offsite fills placed in the' eastern portion of the site while grading the adjacent Laguna Riviera subdivision., During this period loose surface soils were excavated from areas to receive fill. The excavation bottoms were scarified, watered, compacted and fill material placed. All lots in Phase 2 are fill lots except 11, 12, and 22 which are cut-fill lots. In Phase 3, lots, 9 through 18 are cut-fill lots and 19 and 20 are cut lots. The depth of fill below building pads ranges from 0 to 20 feet for Phase 2 and 0 to 5 feet for Phase 3. The' greatest difference in fill thickness on any individual pad was 10 feet for Phase 2 and 5 feet for Phase 3. During the regrading operation compaction procedures were observed, and field density tests were made to help evaluate the relative compaction of the fill. Field density tests were in accordance with the AS TM Test Method No. D2992-81 (Density of Soil and Soil Aggregate in Place by Nuclear Methods). Maximum dry density and optimum moisture content measurements weJ;'e made in accordance with the Test Method ASTM D 1557-78, (Moisture-Density Relations of Soils and Soil-Aggregate Mixtures) . A buttress fill was constructed to the rear of lots 4 through 11 in Phase 2 in accordance with recommendations. The buttress consisted of excavating the design cut slope starting at the slope top and extending down to a 15 ./' foot wide key. A subsurface drain was installed in the buttress cut and the excavation was filled with compacted soil. The slope surface was ) , overbuilt and trimmed to design slope. The reader should be aware that the preCIsIOn of the field density tests and the maximum dry density tests is not exact and variations should be expected. For example, the American Society for Testing and Materials has recently investigated the precision of the test Method ASTM No. D1557-78 and has concluded the accuracy of the maximum dry density is 4 percent of the mean value and the optimum moisture content is accurate to 15 percent of the mean value; the Society specifically states the "acceptable range of two results' expressed as a percent of mean value" is the range stated above. In effect, an indicated relative compaction of 90 percent could have an acceptable range of accuracy of 86.5 to 90 percent and 90 to 93.8 percent based on maximum dry density determinations. The precision of the field density test Method ASTM D1556-82 has not yet been determined by the American Society for Testing and Materials; however, it must be recognized it also subject to variations in accuracy. In Native Sun Develo.ent Project No. 51101B-FC01 November 1, 1985 Page 3 • Woodward· Clyde Consultants summary, the observations of construction and field density testing procedures used follow normally accepted procedures which are not exact, and variations in relative compaction should be expected in lateral and vertical extent and upon retesting. Subject to the precision limitations discussed above, field observations and results of field density tests indicate that the fill has been generally compacted to 90 percent or more of dry density as determined in accordance with Test Methods ASTM No. 1556-82 (D2922-81) and No. D1557-78. For reference, the approximate location of field density tests and the limits of compacted fill have been recorded on a copy of the grading plan. The results of field density tests, expressed as a percent of maximum laboratory dry density (relative compaction), are given on the attached forms. Laboratory tests were made on representative samples of the materials used for fill. The tests were performed to evaluate moisture-density relationships, maximum dry density, optimum moisture content, grain size distribution, plasticity, and swell characteristics. The results of laboratory tests are attached. SUMMARY OF FINISH GRADE SOIL CONDITIONS During the regrading operation, certain lots were specially treated to provide a specified depth of select soil at rough grade. PHASE 2 Observation and laboratory tests indicate that the fill placed within 3 feet of finish grade lots is classed as moderately expansive; these soils exhibited a swell of 4 to 9 percent on samples recompacted at optimum moisture content, placed under an axial load of 160 psf, and soaked in water. On lots 1 through 11, 19, 20 and 22 through 24 topsoils and highly expansive soils were excavated along daylight lines and replaced with moderately expansive fill to a depth of 3 feet below finish grade. PHASE 3 Observation and laboratory tests indicate that the fill placed at finish grade on the filled portion of lots 9, 17, and 18 can be classed as low in potential expansion. The fill placed. at finish grade on the filled portion of Lots 10 through 16 can be classed as moderate in potential expansion. The cut portion of lot 11 and cut lot 20 were observed at the completion of regrading. The observation indicated that the soils are classed as low to moderate.ly expansive. The daylight line of lots 9 through 16, 17 and 18 were undercut to remove topsoil and clay. Observations of the remaining cut portion of the lots and cut lot 19 indicates low expansive soil to be at finish grade. Native Sun Develo.ent Project No. 51101B-FCOI November 1, 1985 Page 4 • Woodward· Clyde Consultants Finish grade elevations as indicated on the grading plans were changed in order to balance the grading of the project. In Phase 2, Lots 1 through 11 and 22 through 25 were lowered 2 feet, Lots 26 through 32 were lowered 1.5 feet, and Lots 33 through 35 were lowered .5 feet. The recreation lot was lowered 4.0 feet. In Phase 3, Lots 1 through 8 were raised 1.0'. The recreation lot in Phase 1 was lowered 2'. RECOMMENDA TIONS Foundations On All Lots Phase 2 and Lots 10 through 16 Phase 3 We recommend that foundations for single-story or two-story multi dwelling residential structures placed on moderately expansive properly compacted fill be designed for a bearing pressure not exceeding 2,000 psf (dead plus live loads). We recommend that footings be founded 18 inches below finished grade. Footings should have a minimum width of 12 inches. In our opinion, this bearing pressure can be increased by no more than one-third for loads that include wind or seismic forces. We further recommend that No. 3 dowels be placed in footings and bent down and tied to the floor slab mesh. The dowels should be 18 inches on center, 16 inches into the slab and embedded 12 inches into the footing. Foundation on Lots 9, and Trhough 20 Phase 3 We recommend that foundations for single-story or two-story multi dwelling residential structures placed on low to moderately expansive undisturbed soil or properly compacted fill be designed for a soil bearing pressure not exceeding 2,000 psf (dead plus live loads). We recommend that footings be founded at least 12, and 18 inches below finished grade for one and two story structures, respectively. Footings should have a minimum width of 12 inches. In our opinion, this bearing pressure can be increased by no more than one-third for loads that include wind or seismic forces. Concrete Slabs-On -Grade We recommend that the moisture content of the soils in the upper 2 feet of grade not be allowed to dry prior to placement of concrete; this may require that periodic sprinkling be employed. Moisture content tests should be obtained on each lot to verify proper soil moisture content prior to trenching for footings. Concrete Slabs-on-Grade-Living Portions of Structures We recommend that concrete slabs on grade be a mInImUm thickness of 4 inches and be reinforced with 6 x 6 10/10 welded wire mesh (flat sheets). An underlay of 4 inches of coarse sand and a vapor barrier should be employed. Native Sun Develo.ent Project No. 51l01B-FC01 November 1, 1985 Page 5 Concrete Slabs-on-Grade Garages • Woodward· Clyde Consultants We recommend that garage slabs be a minimum 4 inches in thickness and placed independent of perimeter footing. Reinforcing of 6 x 6 10/10 welded wire mesh (flat sheets) should be at the center of the slab. Exterior Concrete Flatwork We recommend that contractual arrangements between the builder and the subcontractor constructing concrete patio slabs, sidewalks, driveways and garage slabs hold the subcontractor responsible for proper preparation of the sub grade prior to placing concrete slabs. Our services in connection with this project do not include design slabs or inspection prior to placing concrete slabs, hence we will not accept any responsibility for performance of exterior slabs. Slopes Fill slopes at the site have inclinations of approximately 2: 1 (horizontal to vertical), and are approximately 30 feet high. Fill slopes were treated by overfilling, compacting, and then cutting back to grade. Slopes were also periodically backrolled with a sheepsfoot compactor. We recommend that structures that will not tolerate differential settlements (such as foundations, swimming pools, concrete decks and walks, walls, etc.) not be located within 8 feet of the top of a slope. We recommend that footings that are located within 8 feet of the top of a slope be extended in depth until the outer bottom edge of the footing is 8 feet horizontally from the outside face of the slope. Additional Fill and Utility Trenches This report discusses the fill placement observed by personnel from our firm during the period specified. We recommend that any additional fill placed, as well as backfill 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 and tested to verify compliance with the earthwork specifications for the project. We should be contacted at least 24 hours prior to backfilling operations. Drainage We recommend that positive measures be taken to properly finish grade each lot after structures and other improvements are in place, so that drainage waters from the lot and adjacent properties are directed off the .. ' ; Native Sun Devel.ent Project No. 5H01B-FC01 November 1, 1985 Page 6 • Woodward·Clyde Consultants lot and away from foundations, floor slabs, and slope tops. Even when these measures are taken, -a shallow ground-water or surface-water condition can and may develop in areas where no such water condition existed prior to site development; this is particularly true where a substantial increase in surface-water infiltration results from landscape irrigation. LIMITATIONS With exception of those lots previously noted the elevations of compaction tests shown as finished grade (FG) tests on the attached forms correspond to the elevations shown on the Grading Plans for Carlsbad Tract 82-6 Laguna Del Mar, dated June 19, 1985, prepared by Land Space Engineering Co. Elevations and locations used in this report were based on field surveys done by others. 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. We will examine foundation excavations for each lot if we are requested to do so. For this report, rough lot grade is defined as that grade set in the field by the grade checker from reference stakes established by the surveyor, and represents rough grade at the time we were observing the grading operation removal and replacement of highly expansive soils. Likewise, the indicated depths of undercutting of expansive soil and/or depths of placement of compacted fill soil were based on the measurements made by and grades set by the contractor's grade checker. The conclusions and OpInIOnS drawn from the test results and site observations apply only to our work with respect to regrading, and represent conditions at the date of our final site visit. 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. 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 care of our profession at this time. We do not guarantee the performance of the project in any respect.

SCOPE OF WORK Our services include: o o o o Providing periodic engineering observation of the grading opera- tion; Performing field density tests in the placed and compacted fill; Performing laboratory tests on representative samples of the material used for fill; Providing professional OpInIOnS regarding the contractor's gener- al adherence to plans and specifications. SUMMARY OF GENERAL EARTHWORK AND TESTING Site preparation, compaction, and testing were done between July 25 and October 10, 1985. In our opinion, based on our observation and testing, the work performed during that period of July 25 through October 10, was in general conformance with the Guide Specifications for Site Grading attached to our report entitled "Update Geotechnical Investigation, Laguna Del Mar, Carlsbad Tract 82-6, Carlsbad, California," dated February 25, 1985. Consulting Engineers. Geologists and EnVIronmental SCientists Offices in Other Pnnclpal Cit!es Native Sun Devament Project No. 51101B-FC01 May 20, 1986 • Woodward-Clyde Consultants Page 2 The grading consisted of the removal of loose natural soils and the place- ment and compaction of fill material to bring the pads to design grade. All the subject pads are underlain by compacted fill to depths ranging from 1 foot to approximately 18 feet. The north sides of the lots are generally in cut or shallow fill and a fill slope extends along the south sides of the lots. . During the grading operation certain earthwork operations were observed. These include: o o Alluvium and loose topsoil removal; and Observation of fill placement and compaction to approximate elevation 26 to 27 feet (MSL). The upper approximately 5 feet of fill, placed from elevation 26 to 27 feet to finish grade elevation (approximate elevation 31 to 32 feet), across the subject lots was not observed by our firm. The grading contractor indicated to us that the same equipment and method of operation were used in placement and compaction of the upper portion of the fill as was used in other portions of the fill. Field density tests taken by us in pits dug into this upper fill after completion of site grading indicate above 90 percent relative compaction. Field density tests were in accordance with Test Method ASTM D1556-82, (Density of Soil in Place by the Sand-Cone Method) or D2922-81 (Density of Soil and Soil Aggregate in Place by Nuclear Methods). Maximum dry density and optimum moisture content measurements were made in accor- dance with Test Method ASTM D1557-78, (Moisture-Density Relations of Soils and· Soil-Aggregate Mixtures). The reported tests represent the relative compaction and water content at the locations tested. The observations of construction and field density testing procedures used followed normally accepted procedures which are not exact. The accuracy of the maximum dry density determination (Test Method ASTM D1557-78) is discussed in the 1985 Annual Book of ASTM Standards, Section 4, Volume 04.08 "Soil and Rock; Building Stones". Variations in relative compaction should be expected in lateral and vertical extent. Subject to the limitations discussed above, field observations and results of field density tests indicate that the fill has been generally compacted to 90 percent or more of maximum dry density as determined in. accordance with Test Methods ASTM D1556-82, D2922-81 and D1557-78. For reference, the approximate location of field density tests and the limits of compacted fill have been recorded on a copy of the grading plan. The results of field density tests, expressed as a percent of maximum laboratory dry density (relative compaction), are presented on the attached forms. Native Sun DeAment Project No. 51101B-FCOI May 20, 1986 Page 3 e Woodward·Clyde Consultants Laboratory tests were made on representative samples of the materials used for fill. The tests were performed to evaluate moisture-density relation- ships, maximum dry density, optimum moisture content, grain size distribution, plasticity, strength, and swell characteristics. The results of laboratory tests are attached. SUMMARY OF FINISH GRADE SOIL CONDITIONS Observation and laboratory tests indicate that medium expansion fill was placed within 3 feet of rough grade on all pads noted herein. This con- clusion is based on the results of an Expansion Index Test performed in accordance with Uniform Building Code Standard 29-1. The results of the Expansion Index Test indicate an Expansion Index of 85. We do not know that all the fill in the upper 3 to 5 feet of grade on the subject lots is represented by the density tests taken in this zone. We do understand that the contractor has issued a letter stating that the place- ment and compaction methods used in this zone were the same as those applied to other fills on site that were observed by Woodward-Clyde Con- sultants. RECOMMENDATIONS Footings Subject to the finish grade conditions noted above, it is our opinion that foundations for single-story or two-story multi-dwelling residential structures may be designed for a bearing pressure not exceeding 2,000 psf (dead plus live loads). We recommend that footings be founded at least 18 inches below finished grade, and have a minimum width of 12 inches. In our opinion, this bearing pressure can be increased by no more than one-third for loads that include wind or seismic forces. Steel reinforcing is recommended in concrete footings. We recommend at least one No. 4 bar top and bottom in all footings. We further recommend that dowels be placed in the footings every 18 inches on center and bent down into the slab 18 inches. Concrete Slabs-On-Grade In living portions of the residences, we recommend that the floor slab be at least 4 inches in thickness and reinforced at the midpoint with 6 gauge steel mesh. The mesh should be tied to the footing dowels. An underlay of 4 inches of coarse sand or crushed rock is recommended beneath the slab. A vapor barrier should be used above the capillary break and a 1-2 inch layer of wetted sand for protection of the barrier. For garage slabs, we recommend that the floor be structurally separate from the perimeter footings and that it be reinforced with 6 gauge mesh at the midpoint. Native Sun Devament Project No. 51101B-FC01 May 20, 1986 Page 4 Sub grade Preparation e Woodward·Clyde Consultants We recommend that the upper 18 inches of soil on the lots be remoisturized to at least 5 percent above optimum prior to pouring footings or concrete slabs-on-grade. These recommendations are intended to reduce the effects of heaving of the expansive clay soils and not to prevent heaving. Foundations placed on clay soils should be expected to heave. Slopes Fill slopes mately 2:1 Fill slopes to grade. bordering the lots on the south have inclinations of approxi- (horizontal to vertical), and are approximately 12 feet high. were treated by overfilling, compacting and then cutting back A retaining wall extends along the toe of the slope. We recommend that structures that will not tolerate differential settlements (such as foundations, swimming pools, concrete decks, walks, walls, etc.) not be located within 8 feet of the top of a slope. We recommend that footings that are located within 8 feet of the top of a slope be extended in depth until the outer bottom edge of the footing is 8 feet horizontally from the outside face of the slope. Additional Fill and Utility Trenches This report discusses the fill placement observed by personnel from our firm during the periods specified. We recommend that any additional fill placed, as well as backfill 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 and tested to verify compliance with the earthwork specifications for the project. Drainage We recommend that positive measures be taken to properly finish grade each pad after structures and other improvements are in place, so that drainage waters from the pad and adjacent properties are directed off the pad and away from foundations, floor slabs, and slope tops. Even when these measures are taken, a shallow ground-water or surface-water condi- tion can and may develop in areas where no such water condition existed prior to site development; this is particularly true where a. substantial increase in surface-water infiltration results from landscape irrigation. Exterior Concrete Flatwor k We recommend that contractual arrangements between the builder and the subcontractor constructing concrete patio slabs, sidewalks, driveways and garage slabs hold the subcontractor responsible for proper preparation of Native Sun nevelment Project No. 51101B-FC01 May 20, 1986 Page 5 e Woodward-Clyde Consultants the sub grade prior to placing concrete slabs. Our services in connection with this project do not include design of slabs or inspection prior to placing concrete slabs. LIMITATIONS The elevations of compaction tests known as finished grade (FG) tests on the attached forms correspond approximately to the elevations shown on the "Grading Plans for Carlsbad Tract No. 82-6,'" dated June 19, 1985, prepared by Land Space Engineering Company. We understand that the pad grades were raised approximately 1 foot at the end of the grading period. Elevations and locations used in this report were based on field surveys done by others. 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. We will examine foundation exca- vations for each pad if we are requested to do so. For this report, rough pad grade is defined as that grade set in the field by the grade checker from reference stakes established by the surveyor, and represents rough grade at the time we were observing the grading operation. The conclusions and opinions drawn from the test results and site observa- tions apply only to our work with respect to grading, and represent conditions at the date of our final site visit on October 19, 1985. 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 advise, opinions or conclusions relative to site preparation (clear- ing, grubbing, canyon clean-out, and installation of canyon sub drains 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 under- standing of the proposed construction, and partly on our general experi- ence in the geotechnical field. Our engineering work and judgments rendered meet or exceed the standard care of our profession at this time. We do not guarantee the performance of the project in any respect.

The design recommendations are based on the attached R-value tests pel'formed on representative' samples of the near-surface soils by Testing Engineers -San Diego. "The anticipated sub grade material will be comJ?acted silty to clayey sand. The R-value tests gave results as follows: Street Neblina Drive (Near intersection with Park Drive) Neblina Drive Windjammer Way Flying Cloud Way Argosy Lane Station 1+00 9+50 3+00 9+00 8+00 .. :-.

Prior to placement of base material, we recommend that the top 12 inches of subgrade be scarified, watered as required, and compacted to a minimum of 95 percent of the maximum laboratory density' as determined in- ~ccordance with ASTM Test Method D-1557-78A. We recommend that landscape and pavement areas be properly drained to reduce the potential for water entering the sub grade beneath these areas. If you have any questions, please give us a call. .

Natural s.nclinations vary from a. m~xirnum' . O'f, approximately 2 to 1 on' the . ridge flanks:, to·, nearly flat. on· sections of the ridge top. Vegetation varies from a sparse growth of grasses in the southern regions tq'moderate to dense. brush along the drainages and western sections. Compacted fill soils, placed in conjunction with the grading of Unit·s .. lD' and 11, are present in drainages along the eastern sj. te bound-', ary.

We understand tha:t two water linescro~s the north- ern most corner of the property with one line paralleling the northwest boundary line. Sewer and electrical utilit,i.es are present along Park Drive . ••••• • .. . . Sub.surface Conditions The site· is underlain by compacted fill soils, top- soil, Pleistocene age terrace deposits and the Eocene . age Santiago Formation. These units are des,cribed ):)elow.i their 4 ' .. Reference No. SllOlW-SIOl Woodward-Clyde Consultants ' areal extents, with the exception of the topsoil, are approx- ima~ely shown on Fig. 1. The geologic' map symbol for each uni t is given after the formal name for the unit. Fill Soils (Qf) -Undocumented fill soils, estiIQated·· to b.' up to approximately 8 feet in thicknes~ i a·1"e -present ih drainage swales along the eastern boundary. These so~ls I visually classified as silty sands, appear to represent a regrading of existing natural drainage swales. Topsoil (unmapped) - A topsoil layer I composed of' compressible silty sand grading to sandy clay, is present on the natural hillsides and beneath the loose fill soils in Test' . . pit 3. It is estimated that these soils range .from.l to 3 feet in thickness. Terrace Deposits (Qt) -The eastern two-thirds of the site is underlain by terrace deposits comp~sedof ,dense,' sil ty to clayey sands containing randomly dispersed interbeds" and lenses of sandy to silty clay. The sandy pottions' were found to r.ange from lightiy cemented to cohesionles'sand .non- . expansive to moderately expansive. The clay layers. are gener-' . ally highly expansive.

This orientation rep- resents a potentially adverse co~di tion for all $outh-facing cut slopes. No faults or indications of' faults were observed during our reconnaissance, and no faults are mapped on the site. Landslides, Our studies did not reveal the presence of land- slides on the site.

DI.SCUSSIONS, CONCLUSIONS, AND RECOMMENDATIONS The discussions, conclusions, and recommendat':ions presented in this report are based on the results of our field' and laboratory studies', previous work in the area, analyse.s, and professional judgment. Potential Geologic Hazards Faulting. an~ Ground Breakage -Our· reconnaissance, literature review, and subsurface explorations did not reveal the presence of any faulting on the site. The nearest known acti Ve fault along which 'seismic events of .magnitude 4 or greater have occurred is, in the.' Elsinore Fault zone, mapped some 22 miles to the nox-theast. 6 • I" Reference No. SllOlW-SIOl Woodward· Clyde Consultants The ,closest signif~cant faulting is the northern extension of the Rose Canyon Fault zone, .which is mapped off- shore approximately 9 miles to the southwest. No magni~ude'4 or larger earthquakes have been recorded on the l\ose Canyon Fault zone. Liquefaction -The formational soils on' the sj, te a,re' dense to very dense, and there is no apparent 'water table within expected grading limits. the' formational soils do' not .. have a liquefaction. The topsoils have a potential permanent' ,ground. In our opinion, potential for- for liquefaction in a saturated state. In our opinion, this potential can be essentially eliminated by over-excavation and recompaction'as recommended under "Grading." Landslides -Our review and, field investigations did not. reveal the presence of any landslides on the site. Ground, water Our field investigation did n9t reveal' a,~y ground water seeps, springs " or abnormally wet areas anq 'we do hot expect that a shallow permanent ground water tabl:e is' p+,esent ' within the proposed grading limits. We recommend that positive measures betaken to,' properly finish grade each lot after the residential struc- tures and other improvements are in ~lace, 80 that drainage waters-from the lots and adjacent properties are directed off the lots and away, from house foundations, floor sl.abs I and slopes.

General soil Conditions The materials expected to be used in structu,ral fills and in constructed slopes are primarily silty to clayey ,sands containing sandy and sil ty clay interbeds. In our opinion, the soils on the site can generally be excavated to 4esign depths by light to moderate effort by, heavy-du~y excavation equipment. Excavation of localized cemented zones in the Santiago Formation may requi~e heavier ripping, and may result in the generation of, oversize' material. soils suitable for use at finish gradearepres~ilt in the formations underlying the site; however, clayey strata have been identified in the' excavations. 'l'he ,cl:aYPo.T;tipns, of the formational soils and surficial soils are highly expans,ive, and unsuitable for use at' finish' grade. Selective gradihgmay be required including stockpiling of finish grade soils i1) order to arrive at satisfactory finish grade conditions. Slope stability We have performed stability analyses for the,pro- posed slopes by the Janbu method, using the following parameters: Parameter Undisturbed materials ,Compacted Fill ..!. 33° 25° 8 c' ,::1.. --'!o 300 psf 125 paf ".~:~:",:, 300 psf 125 pcf '. Reference No. 5ll0lW-SIOl Woodward· Clyde Consultants. Our selection of soil parameters for analysis is based on the results of laboratory tests performed on samples during our field explorations and from studies on similar' formational soils in the Carlsbad area. The results of those ana·lyses, ind:i,cate tbat tbe' proposed 2 to 1 inclined fill and cut s~opes, if fre~ o:f' claystone interbeds, have calculated factors· of $aft!ty against,' de,ep-seated slope failure in excess of 1.5 for static condi- tions. Slope stability calculations are attached (Appen- dix 0). South-facing slopes made in the terrace deposits may expose weak, southerly dipping, clay seams. It is our pro'fes- slonal judgment that cut slopes in excesS of 10 feet in height,' wi th exposed weak clay seams have a moderate potential for slope instability if constructed as indicated. We recommend buttressing south-facing cut slopes with. exposed weak clay seams that are in excess of ~O feet ·in. height in accordance with the .following sketch (seepage 9A) . This treatment may necessitate the slopes being; .overbuj..l t ' 3 feet and. cut back to the finish~d grade s~rface. Stabili ty analyses require using parameters s.eleqted from a range of possible values. There is a tinite possibil- ity that slopes having calculated factorS of safety, as indi- " ., t?at~d, could become unstable. .In our opinion, the probability of. slopes becoming unstable is low, and it is our professional" judgment that the proposed slopes can be cons'truc:ted. We recommend that an engineering ge'ol.ogist from our firm inspect all cut slopes during gr~ding to verify actl1'al geologic conditions and to provide design modifications,' if needed. It should be noted that friable, cohesionless sands were encountered in our test borings and may be exposed in the cut slope faces when grading is cOJ;npleted.

The more clayey soils. can be placed and properly compacted in the deeper fill areas. We recommend that the upper 2 feet of materia·ls. in'· the' fill a~eas be composed 'of finish grade, granular soils. Finish grade soils are defined as granular soils that h~ve a potential swell of less than 6 percent when recompacted to' 90 percent of maximum laboratory density at optimum moisture content, placed under an axial load of 160 psf, and. soaked. in. water.

The recommendations made herein are based on the assumption that condi tions do not deviate appreciably from those founq duri'ng our field investigation. If the plans for site devel'optnent> . 'change, or if variations or undesirable geotechnical condi-, . tions are encountered during construction, t.p.egeotechnic~l' consultant should be consul ted for further recommendC!.tions. ' ,',' , , We recommend that the geotechnical consultan~ review all grading and foundation plans before finalizing to ve'rify that the intent of the recommendations presente<:! herein have been· properly interpreted and incorporated into the ,contract documents. We further recommend that the geotechnical C(;>o- 'sul tant observe the si te grading, and subgrade preparation under concrete slabs and paved ar'eas, and foundat~oil excavations. It should be understood that California, is an area of high seismic risk. It is generally considered econotnical:lY :;:..;' ' , ,~ unfeasible to build totally earthquake-resistant. st-ructures; therefore, it is possible that a ~arge or nearby ea~thqua'ke could cause damage at the site.

GENERAL These 'specifications cover preparation of existing .surfaces . to rece.ve fills, the type of 80il suitable. for use' ip. .fills",.' the· control-of compaction, and the .methods of tes:tj·ng:. co~p'aei.. ted fills. It shall be the coiltr:a,ctor' s -responsibilt·ty. to place,-spread, water, and compact the fill in strict accord- ance with these specifications. A soil ·~ngineershall b.e the owner's representative to inspect the construction of fills'. Excavation and the 'placing of fill shall be under the direct inspection of the soil engineer, and he shall give written notice of conformance with the specifications upon .completion of grading. Deviations from these specifications will be- permitted only upon written authorization from the soil· engineer. A soil investigation has been made for ·th~s pro- ject; any reconunendations made in the report of the .soil .investigation or subsequent reports shall beGome an ad4endum to these specifications. II. SCOPE The placement of controlled fill by the contractor shall include all clearing and grubbing, removal of existing unsat- isfactory material, preparation of the a're,as to' be f.tIled', spreading and compaction of fill in the areas to be filled, and all other work necessary ·to comple:te the grading of'the filled ar.~as. III. MATERIALS ,'1.. Materials for compacted fill shall consist 'of any mater ... · ial imported or excavated from the cut areas that, in the- opinion of the soil engineer, is sui table for lise in con- structing fills. The material shall contain no rocks or hard ·lumps greater than 24 inches in size and shall contain at least 40% of material smaller than 1/4 inch in size. (Mater- ialsgreater than 6 inches in ·size ·shall be placed by the " contractor so 'that they are surrounded by ·compacted fines; no nesting of rocks shall be permitted.) No materi~lof a perishable, spongy, or otherwise improper na,ture, shall be . used in filling. ' , 2.. Material placed within 24 inches of rough grade shall be 'select material that contains no rocks or hard lumps greater, than 6 inches in size and that swells less than 6% when compacted as hereinafter specified for compacted fill and soaked under an axia~ pressure of 16:0 psf. E-1 · ,., 3. Representative samples of material to be used for fill shall be tested in the laboratory by the soil ~ngineer in order to, determine the maximum density, 'optimum moisture content, and classification of the soil. In addition, the soil engineer shall deterlQine the approximate bearing value of a recompacted, saturated sample by direct shear tests or other tests applicable to the particular soil. 4. D.uring grading operations, .oil. types-' other than,those' analy~ed in the report" of the soilihvest1g.-tion may p'e·. encounte;-ed. by the contractor. The soil engineer snaIl . be consulted to determine the suitability of these soils. IV. COMPACTED FILLS 1. General (a) Unless otherwise specified., fill material shall be compacted by the contractor whil'e at a moisture content near the optimum moisture content and to a density 'that is not less than 90% of the ,maximum dry depsity deter-: mined in accordance with ASTM Test No. D1.S.',. .0 , ·or other density test methods that will, ~btai~ ?:~... . '.' .alent' resul ts . " ,. " .. . (b) Potentially expansive soils may be ·used in fills below a depth of 24 inches and shall be compacted~t a moisture content greater than the optimum, moisture content for the material. ' 2. Clearing and Preparing Areas to be Filled (a) All trees, brush, grass, and other objectionable mater- ial shall be collected, piled, and burned or otherwise disposed of by the contractor so as to leave' the .areas that have been cleared with 'a neat and finished appear- ance free from unsightly debris.. . (b) All vegetable matter and objectionable mat~rial shall be removed by the contractor from the surface upon which the fill is to be placed, and any loose or' per-ous soils shall be removed or compacted to the depth shown on the· plans. The surface shall then be plowed or scarified to , a minimum depth of 6 inches until . the surface is free from uneven features that would tend to preven:t. uniform compaction by the equipment to be used. , ' . ( c) Where fills are constructed on hillsides, or slopes, the slope of the original ground on which the fill is :to be placed shall be stepped or· keyed by the contracto,r as shown on the figure on Page 4 of these specifications. The steps shall extend completely through the soil mantle and into the underlying formational materials. E-2 (d) After the foundation {or the fill has been cleared, p'lowed, or scarified, it shall be disced or bl'aded' by the contractor until it is uniform and free from large clods, brought to the proper moisture content, ,arid compacted as specified for fill. 3. (a) (b) (c) Placing, Spreading, and Compaction of Fill Material The fill material ahall be placed by the contr.ctor in lay~rs that, when compacted, shall, not exceed 6 inc·hes·, Each layer ahall be spread evenly :and'shall,be tho~oU9'h'" .ly mixed during the spreading to. obtain -'uniformity of material in each layer. . . , . .' When. the moisture content of the till. material is' below, that specified by the soil engineer , wat~r shal!' be added by the contractor until the moisture content 'is as. specified. When the moisture content of the fill material is above that specified by the soil engineer, the f·il1· material 'shall ,be aerated by the contractor by blading, 'mixing, or other satisfactory methods until the moisture content is as specified. ' Cd) ,·After each layer has been placed, mixed, ands.J:~read evenly, it shall be thorou,ghly compacte.d by, the contrac- tor to the specified density . Compaction . shall be accomplished by sheepsfoot rollers, vibratory ro.llers, mul tiple-wheel pneumatic-·tired rollers;. or othel; types ,( e) v. ,of acceptable compacting ~quipment. Equipment shall .be of such design that it will be able to compact the fill to the specified density. Compaction shall be continu- ous over the entire area, and the equipment shall make . SUfficient trips to insure that the desired· density has been obtained throughout the entire fill. The surface of fill slopes shall be compacted ana there shall be no excess loose soil on the slopes. INSPECTION .1. Observation and compaction tests sh,all b~ made ,bY the soil engineer during the filling and compacting operations SO that he can state his opinion that the fill was constructed, in accordance with the specifications. 2. The soil, engineer shall makf;! field, density tests in 'accordance with ASTM Test No. D1556-64. Density',tests Shall be made in the compacted materials below the surface where the surface is disturbed. When these tests indicate that the density of any layer'of fill or portion thereof is below the '.specified density, the, particular layer or portion 'sh'all bf;! reworked until the specified density has been obtained., E-3 .. ,. VI. PROTECTION OF WORK 1. During construction the contractor shall properly gra(ie all exoavated surfaces to provide positive drainage and prevent ponding of water. Be shall control surface water to avoid damage to adjoining properties or to finished work on the site. The contractor' shall take remedial measures t9 ,preven~ erosion of freshly graded areas and until suc;:h time as ,permanent drainage and erosion control features have. been installed. 2. After cOInRletion of grading and when the soil ·engineer has finished h~s observation of the work, no further excava- tion or' filling shall be done except under the observa,tion' of the soil engineer. Strip as specified Original ground Slope ratio = N M Remove all topsoil NOTES: The minimum width of "B" key sl)all be 2 feet wider than the compaction equipment, and not les,s than 10 feet. The outside edge of bottom key shall be below topso.il· or loose surface material. Keys are required where the natural slope is steeper than' 6 ,horizontal to 1 vertical, or where specified by the soil engineer. E-4 ' .. APPENDIX F GUIDE SPECIFICATIONS FOR SUBSURFACE DRAINS I.

This property" which cove,..s a,n are'a of 29 acres, has been designated as a5. La'guna Ri ver.ia CT80 . . Planned for construction are single and multi-family wood-frame dwelling lmits to be: founded on graded building sites. It is expected that the structures will be con- structed on both continuvu& and pad footings \.dth ~lab­ on-grade cuncrete floors. ~he exact structural loads for the buildings are un,known a,t this time. HOwevcr, for the pl:.rpO&E of analysis,' it has been assumed that c.ontinuous fovtings will. carry 1200 p~)und s per Ii nea I foot of whi,c h 90 ptrcent is dE.:'ad' load' and that pad footings \dll carry 15 kips each of vih.i,ch 50 percent is dead load. If it .i~ found th~t the act"lJai 'loads are' substantially different, ·from those ,assumed, t,his office should be notified for reevaluation. FIELD INVESTIGATION The first phase of the field investigation .,consisted of ex'cava,ting four exploratory borings to depths·' of 20 feet. These borings were drilled in the lower fill, a're'a using a 16 inch bucket auger drilling rig. Select.d s~eriimen$ of the in situ soils were obtained-by usiq~ a2.5 ,inch I.D. drive tube' sampler equipped. with. bra-5s' line'l", rings. In addition to these relatively undis't:;urbed': 'specimens, bulk samples of the soil s wen~ obtained for additional laboratory analysis. In addition to the borings, ten exploratory p~ts ~ere excavated to depths ranging from 5 to 11.5 feet. The exploratory pi ts were excavated using a hydraulic .. backhoe @ KENNETH G. OSBORN~ "ASSOCIATES Job No.' 3379-1 Page 2 mounted on a rubber-tired tractor and the condition of the earth materials was d~termined visually and by standard densi tytesting. These test specimens', bulk samples of the soils, w~re also obtained for ad~i'tion:al laboratory analysis:. These soil samples and the sampl.es obtained from the exploratory b0rings served as the basis for ch~ laboratory testing and the geotechnical conclu~ionS cont,ained in this report. The l,-,&s of the borings and test pits a~d a gco-, and test pit technical map showing ap~ate -boring locations are included wit~, "report. , ' ~ The elevations shown on'''': e boring and as 'well as their location in the field were test pit log~ det€:'rmi ned by interpolating from contours shown on the topographic map (Scale 1"=40' )of the property as prepared by Rick Engineer- ing Company Df Carl~bad, California. LABORATORY TESTING The laboratory testing consisted of performing cla~bi­ fication, strength, settlement, soluble sulfate, and, e~pansion tests, determining in situ' dry density and moisture content, and determining the moisture-densi ty relatioftship of major soils. Descriptions of test standards used in this, investiga- tion, in addition to other tests not used, in this investiga- tion, are included in the Appendix of this report. SITE DESCRIPTION The site at the time of the field ,investig~tioh consisted of an irregular shaped parcel in the moderately dissected coastal foothills of Carlsbad~ California. The property slopes southerly from Nebl ina Drive' (elf:~v. 120::} , to Park Avenue Celev. 13.0!) and a prominent canyon along the proposed alignment of Neblina Drive bisects the project. @ KENNETH G.

GEOLOGY GeQlogic Setting The 5ubjt'ct area is a tYFic.::l pu r t i em of wfstern Sci2n Diego county. Bedrock I:; a ~€:'Yie~ of flat ,lyir:g ~E'd imen- tary rvcks.

Se.i smi ci ty There are no known active faults in or n~ar th~ subject area. The nearest known active fault, th~ Elsinc..'re Faul~, l~es approximately 30 miles to the east. It is believed to be capable of an M7~ earthquake which would not seriously affect the Carlsbad area. A fault which may connect the Newport-Inglewood· Z,on'e with .the Rose' Canyon Fault lies 'off-shore about 10. mile,s-. The a,ctivity of this fault is controversial but 'its distance and unc,ertainty rule it out as a majo,r threat to the 'proposed development. The San Miguel fault, i~ Baja, " , California, is likewise of minor concern. Although ·it is., known' to be active, it is too distant to adversely affect, the Carlsbad area. KENNETH G. OSBORNE & ASSOCIATES Job No. 33-j9-1 Page 4 The probabi Ii ty of ground rupture due to sei smi c 'activity is very low. There is little ch~nce that a s~ismlc sea wave (Tsunam.i) would damage the propo!:.ed buildings, however, su·~ging produced by a Tsunami is a 'factor to be cQnsidered if-shoreline development sh~uld be undertaken in the future. 'The water table may be Jo\o.; enough in the flat ~rea to technically permit liquefaction, but the fine' grained ~ediment type is nor conducive to that rh~nom~n0n. Artificial Fill, Qaf and Q~l/u.c. The flat area betv,een Park Dri ve and thE-1 a,goon is covered by 10 to 12 feet of fill composed of v~riou& amounts of sand, Silt, and clay.

Structural Features Be.dding: Stratification, .... lhich is d pccrly developed sub-planar structure, is present in all of the Santiago Formation. However, bedding does nt~ present' a plane of geologic;~.kness. Fissility does not present a geologic weakness except locally in very silty, clayey beds such as shale. ~wing to th~ prevalence of cross bedding, lensing, and related features, it is difficult to' state the ·preci.se attitude of bedding. However, some of it app~ars' to' dip southward (toward the lagoon) a-t a 10 .... ' angle, of- about 8 to 10 degrees. Faults: Faults are .relatively rare in . this' region. No faults, or structures attributable to faulting, were found during the course of this investi- gation. Just west of the most westerly part 'of the @ KENNETH G. OSBORNE" ASSOCIATES , , Job No. 3379-1 Page 5 tract there is a zone of fracturing in the Santiago Formatidn. This zone shows no displ~cement and it 4\' trends in a direction which precludes it from pas.sing ~hrough the project site. G:round Wa t er Water was encountered in boring~ in the low l~nd betwee.n Park Drive and the lagoon at an elevation which suggests that the water table is approximately at sea level. None of the exploratory excavations in the remainder of the property· encountered the water table. There are no springs, seeps, or zones of excess moisture. Formations Colluviu~ (Residual Soil): Mc.·st of the tract i~ overlain by a fe\>.' inches to several feet. of poo.rly indurated sandy material which migh,t be termed residual soil. Locally it is clay-rich ~nd expansive. Lagoonal Deposits, Map Symbol Qal an.d QS\\): aorings in the flat land south of Park Drive en~ countered green to gray silty and clayey sediment with a few sandy streaks. Evidence of organic materialiS;;:' common and moisture content is 'high to very high. Small areas of silty and sandy sediments contain- fng marine shells occur a few_~t above sea level. They probably represent sedimentation whi,ch took plac:e. when sea level w.as higher (or' land' level lower).' These deposits are probably the outer margin of lagoonal deposits in and around the present lagoon. Santiago Formation, Map Symbol Ts: This formation, which is correlated with tbe E;ocene Del Mar Formation, is chiefly sandstone but interbeds of siltstone and shale are common. The sandstone ra·nges @ KENNETH G. OSBORNE .. ASSOCIATEs Job No. 3379-1 Pa.ge 6 from fine to coarse-grained, locally pebbly, and is, moder~tely well cemented. There are local areas of very well cemented sandstone. Indi vidual beds ar~ one to 3 feet thick and show ccmsiderable late'ral variation, such as cross bedding and channelling' with zones which are poorly cemented and are easily 'eroded. SOIL ENGiNEERING Gen~ral Conditions Two distinct conditions exist on this site which influence the development of the project. Ar> artificial fill has been placed over the laguon sediments at an undeterrr.ined time in' the pa~~.: The- ~ediments under t~is fill are very s0ft and exhibited hfgh consolidation poten.tial. Additional filling in thi~ area' ~ill result in substantial settlement. Development of that area east' of Park Drive will c0nsist of constructing a &erie~ of terraces for !:.trf'E:ts ,and houses which will invulve cutting from the sandstotl:e and Si~tstone bedrock and placing compacted fills. This' development type is expected to result in slopes which "'i1.l be fill over cut and building sites with both cut and filla The ,slopes are planned at 2:1 slope ratio. Lagoon Fill -Artificial Fill :Four test borings and eight test pits w~re 'ex'cavated within the fill area near the lagoon· to determine the' c~mdition of the fill. These excavations indic'ate that;: the, fill ranges in depth up to 12-feet. In addition '~'o de'nsi.ty testing to determine relative compaction, ,cotrsolidat.ion tests were performed to establish settle-me,nt potential '0£ the fill. The results of density logs, test pit logs, and included with this report. tests are shown' on the boring the "Table of ,Te'st Results'" @ KENNETH G. OSBORNE .It ASSOCIATES Job No. 3379-1 Pa~e 7 The result~ of tests indicate the fill to pusscss a relative compaction generally in the mid to high 80 percent range. A few isolated .pots of low density (76 to 78%) were found at ..... random which would be expected in most fills.· G~neral settlement characteristics Qf the exi~ting fill are good as indicate on the pressure c'onsolidation curves. Within the anticipated loading from the structures, negligible settlement is anticipated. To insure uniform set t 1 ement, it is recommended that the upper 3. feet o·f the fill be removed and r-ecompac ted wi thi n bui Iding ar€-B!:i so B S to provide a minimum of 18 inches of recornpact.ed fill under footings. ''Deve 1 opment in the lower area should be pI anned so as to minimize the placing of additional fill. Substantial l<?ng-~err;" settlement of the deeper lagoon s~dimlentb will re~~lt from placing add~tional fill&. This bettlement pot~ntial ~hould be reevaluated upon compleri0n. of th~' grading plan. CONCLUSIONS Geologic 1. South facing cut slopes may expose unsupport~d south-dipping strata. The dip angle is' low, the rocks. are not well bedded, and the cuts are not high. However, the possibil.ity of slope instability exists and all c·ut·s should be inspected early in grading so that modifiea·tions or' stabilization· can be made if necessary. 2. Alth~ugh ground water presents no' problems under existing conditions, the increas~, of water accompatiying development could create potential s e.e page problems. In-si tu sandy strata are permeable whereas t.he clayey' and silty interbedded layers are tight and impermeable. Ground water can move down through sandy layers and 'be forced to' move laterally by the clay layers to surfate' at the f~ce of . ~ KENNETH G. OSBORI'iE II< ASSOCIAtES Job No. 3379-1 Page 8 cut slo'pes, or be impounded behind compacted fills. In either case, the resulting pore pressUre .co~ld cause slope instability. Cut slopes should be inspected' for poten~ial seepage· conditions and if determined t.o be unsuitable, slopes should be stabilized and subdrains installed. 3. Seismic hazards existing at this site are, very low. No faults are present on the ~ite and all known active fault.s are far distant enough as to have little effect. The probability of ground rupture, earth sh~king, liquefaction, T~unamis, and other seismic hazards ar~ ab~ent or minim~l. 4. Some of . the clay-rich strata Ln the bedrock are expansive and soils which are clayey are a1s0 moderat.ely to highly expansive. S. Slopes cut in sandy portions of bedrock and/ot sC'i1 possessing little cohesion arE ea~ily eroded .. Prope:r drainage and planting will be: necessary to control runoff on slupes on thi~ project. ;6. Strongly cemented sand!:> tune is exp.0sed in t hi 5 vicinity and it is possible that grading may encounter su~h rock ~hich will be difficult to rip and ""hieh may·gef.lerate 0versize material. So~l Engineering 1. Subject to inspection by the engineering geolog~st, cut slopes made at 2:1 slope ratios are stable~' 2 •. Properly compacted fill slopes ~lacedat a 2:1 sloper4tio are stable. '3. A portion of exi.sting fill (lagoon fill> within th~·· lower area must be recompa·cted. 4. The lower fills possess moderate expansi.on potential. S. Soils derived from cutting the upper areas range from nonexpansiv~ to moderately expansive. 6. Soils on this project possess favorable· s.treng,th char~cteristics. @ KENNETH G. OSBORNE & ASSOCIATES Job No. 3379-1 Page 9" 7. A subdrain system may be required within the main canyon area. 8·. Overexcavation of the cut portion of the cut-fill lats wilL. be requi.red to provide uniform found'a:tion bear-~ng. ' . 9. The lagoonal deposits which underlie'the low, .flat section of the tract may be subject t,o substantial settle- ment if much additional fill is placed. 10. There are no landslides on or near the tract. RECOMMENDATIONS Soil Bearing The site is considered suitable for constructi,on of the proposed facilities using. both continuous and pad footings for support providing the recomr.-;enda t ion's presented herein are follo~ed. Footings may be designed for· an allo~able bearing value of 2200 ~ound~ per square foot for footing~ placed to a minimum width of 12 inche5:. and a minimum depth of 12 inches below the lowest adjacent finished grade. Thi~ value may .be increased to 2600 pounds per square fo<;>tfor footings placed to a depth of 18 inches. An increase of 1/3 of the above bearing value is permissible for shortd'ura- tion l-oading. The above bearing values have been based on footings placed into approved natural ground or t'estedcompacted fill. ' ,Settlement Two basic settlement conditions exist on this project. In the upper areas the natural soils are dense and no~ subject to detrimental settlement. Within'the lower area, structures are planned' on the man-made lagoon fill. Settlement will come from compressiori @ KENNETH G. OSBORNE .. ASSOCIATES ... f , , Job No. 3379-1 Page 10 of the fill due to bui Iding loads and compression or'~er sediments as a result in raising the height of the man-made "~·fill. • To. minimize the differential se.tt lement asa· re·sul t of, bu~ lding loads, 1 tis recomme·nded that the upper' 3 .• 5f e.e·t of· existing fill be removed and recompacted so as to provide a minimum of 24 inches of compacted soi 1 under-the footings. It is impractical to predict settlement of lower sediments since final grades have not been' established. The final grade of the existing fill should not .be sub~ stantially ralsed above that grade now existing. A final evaluation should be made at the completion of the grading plan. Lateral Soil Pre~sure For purposes of designing the structures for lateral forces, an allowable lateral soil pressure of 345 pounds. per sq~are foot per foot may be used f~r the build~ng de·$ign. A coefficient of friction of 0.4 may be used for concrete placed directly on the natural soils. Retaining Wall Design Retaining walls may be designed using the· followi.ng parameters: Bearing ~ 2200 psf Active earth pressure, level backfill -35 psf/ft Sliding coefficient -0.4 Passive earth pressure -345 psf/ft· The nonexpansive natural soils are considered ad~quat~ for backfill of retaining walls. ~etaining walls should be provided with ade~uate dra~n­ ~ge to prevent hydrostatic pressures. @ KENNETH G.

Site Design The soils on the lower portion of this project are expansive and may be subject to' pest-constrUction movement. '~ It is our' opinion that concrete gutters and pavement on this project should be designed and cc;mstr"ucted at slopes adequa t e. to insure proper dra i nage of pcl\'ed area 5 alt er' con!:>truction. It has been assumed, and it· is expe,cted, that the, soil conditions between the borings and pits are simi 1ar"to that encountered in the borings and pi ts. However, no "wa~T'anty of such i's implied in this report. The recommendations contained in this report, a~e "l;>ased on the results of field investigation and 'laboratory testing and represent our best engineering judgment .If soil conditions encountered during the grading, or at any other time, differ substantially from those descri,bed i.n this report, this offi'ce should be ~otified immediately, so that appropriate recommendations can be made.

LABORATORY TESTING PROCEDURES SHEAR STRENGTH The shear strength of the soil is de·termined by per-. forming direct shear tests and unc(;:mfined compr,es.sion· te,sts:o The direct shear' tests are performed on bo,th undisturbed' specimens and on samples remolded to various densities' which reflect anticipated conditions. The samples are either tes~ed at in situ moisture or are saturated to simulate the worst field condition and sheared at a constant rate of 0.'1 inch per minute. The relationship between normal stress and shear stress is shown on the attached Direct Shear summary. The unconfined shear strength of selected undisturbed .specimens is determined in accordance with. A.S.T.M. Tes,t Method 0-2166. The results of these tests are shown on the Boring Logs. EXPANS,ION Tests for volume change with mcisture are perfcrm&d Qfl compacted soil in accordance with Uniform Building Code Te,s't Method 29-2. SETTLEMENT ",i~ .:(;~ The settlement characteristics of the in ~i tu--(:.tsoi1 ,are, determined by performing standard consolidation tests on ·undisturbed or remolded specimens. The samples al;"e tested in the original sample liner ring and the inc:;:remen·t loads . for consolidation are applied for periods of 2. hours by means o'f a .ing-Ie counterbalanced lever system. The pressure settle~' ment curves are shown on the att;ached plates. " MOISTURE DENSITY The moisture-density relationship of. the major soil. , is determined in accordance wi thA. S. T.M.
