In ordc address certain conditions and to provide additional design informatic the design concepts developed, additional geotechnical and coastal neering information was obtained. The purpose of this Design Addei is to present the supplemental information gathered and the addil design criteria developed during this process. Additional information supplemental design recommendations are presented in the following tions . ADDITIONAL GEOTECHNICAL INFORhIATION Additional field investigations were made along the alignment of the pr to better identify the surface soil and bedrock conditions. This 1 consisted of a geologic reconnaissance along the proposed upper 1 walkway, a survey along the face of the proposed seawall and elev; measurements of exposed bedrock surfaces, excavation of eighteen test along the alignment of the proposed seawall and stone revetments drilling of two test borings in the existing parking lot at the south en the project. This work was done during the period between June 3 25, 1986. The approximate locations of the test pits and test borings shown on the Site Plan, Figure NO. 1A. A Key to Logs and Logs of Borings are presented on Figure Nos. 2A, 3A and 4A, respectively. Geologic Reconnaissance - Upper Bluff Walkway The geologic reCOm=.iSSanCe generally consisted of Visual observations field mapping of the exposed natural and fill soils along the prop( Project No. 542681-PD04 alignment of the upper bluff walkway between Pine Avenue and Cf Avenue. The results of the reconnaissance are summarized on thc tached Table No. 1. The area along the top of the bluff is generally covered by a thin lays to 3 feet) of silty sand and gravel fill. Deep fills are located at Wi Avenue (120 feet wide), Sycamore Avenue (20 feet wide), Maple Av (40 feet wide), south of Maple Avenue (100 feet wide), and sout Acacia Avenue (80 feet wide). The fills are generally underlain by sandy terrace deposits. The top of the bluff along the west side of Carlsbad Boulevard from Avenue to approximately 100 feet south of Pine Avenue is relative wide to 20 feet) and flat. The flat portion at the top of the bluff narrow the south of this area and the flat portion generally becomes 5 feet or in width extending to south of Chestnut. There are localized wider a and gullies or eroded areas within this portion of the walkway alignn; Approximately 120 to 130 feet south of Chestnut the top of the 1 widens to about 5 to 10 feet extending to about 200 feet south of h Avenue where it widens to about 15 to 20 feet extending to Ch Avenue. There is one large gully extending into this latter area loc approximately 150 feet north of Cherry Avenue. The slopes extending down from the flat area at the top of the 1 generally have inclinations on the order 13:l (horizontal to vertical) localized flatter and steeper areas. * Bedrock Surface Elevations The alignment of the proposed reinforced concrete seawall and s revetments was surveyed and staked in the field. Elevations of expc bedrock surface on or adjacent to the alignments were measured at sele locations and are summarized on Table No. 2. In areas where bedrock -2- Project No. 542681-PD04 not exposed at the surface, test pits were excavated down to bed (Bedrock was not encountered within the depths explored in Test Pits and T-10) to determine approximate bedrock surface elevations. results of the test pit measurements are summarized on Table 3. In h tion, two test borings were made in the south parking lot to help eval the bedrock surface elevation in this area; Logs of Test Borings presented on Figure Nos. 3A and 4A. In general, the bedrock surface elevations along the face of the reinfo concrete seawall range from approximately +6 feet at the north end (n of Walnut Avenue) up to +10 feet at Sycamore Avenue; it generally ra from +10 to +8 feet from Sycamore Avenue to about 90 feet sout: Redwood Avenue with localized higher and lower elevations; soutk Redwood Avenue the bedrock surface elevation gradually drops down minimum elevation of approximately -2 feet at the south end of the seat The bedrock surface elevation generally appears to drop down to the in front of the seawall at a rate of approximately 1 foot vertical to 4 feet horizonal. The observed bedrock surface elevations along the alignment of the n bluff stone revetment generally range from approximately +6 to +9 feet. estimated that bedrock at the toe of the revetment will be at or 1 elevations +2 to +4 feet. It is estimated that the bedrock surface elevations along the alignmen the lifeguard pad stone revetment will range from 0 to +3 feet, genei decreasing from north to south. The bedrock surface at the toe is timated to be at approximately -1 to -2 feet. It is estimated that the bedrock surface along the alignment of the sc parking lot revetment is at or near approximate elevation -4 feet and it will be below -8 feet at the toe. -3- Project No. 542681-PD04 Additional Geotechnical Design Recommendations Upper Bluff Walkway and Parking Area It is recommended that the upper bluff walkway and parking area subg for concrete sidewalks on grade and asphalt concrete paving be prop prepared and compacted to a minimum relative compaction of 95 percen a minimum depth of 12 inches. All other new fill or backfill shoulc compacted to a minimum relative compaction of 90 percent. Existing left in place should be tested and if less than 90 percent relative ( paction, should be scarified to a minimum depth of 12 inches below exis grade or below the 12 inch subgrade and recompacted to a minimum I tive compaction of 90 percent. It is recommended that footings for the walkway or walkway retaining 'I be designed for a maximum allowable soil bearing pressure of 1,000 Footings should extend a minimum depth of 24-inches below the 101 adjacent grade. For walkways supported on pier foundations, it is recommended that piers be designed as friction piers. Friction values on the perimete: the pier of 0 for the top 2 feet, 500 psf between a depth of 2 and 7 and 1,000 psf below 7 feet may be used for design. It is recommer that the piers have a minimum depth of 10 feet below the lowest adja ground surface and that they have a minimum diameter of 18 inches. estimated that the point of fixity for lateral loads will be at a dept: approximately 5 feet below the lowest adjacent ground surface. It is recommended that retaining walls be designed for an equivalent lat earth pressure of 30 pcf. All backfill materials should consist of SE sand and the walls should be provided with adequate drainage to pre. the build-up of hydrostatic pressures. -4- Project No. 542681-PD04 It is recommended that the pavement in the proposed new parking along the west side of Carlsbad Boulevard north of Cherry Avenue COI of 3 inches of asphalt concrete over 6 inches of Class I1 aggregate bas Reinforced Concrete Seawall Foundation It is recommended that the foundation for the seawall generally be foul on bedrock (Santiago Formation). It is anticipated that, except for south end, the bottom of the footing will generally be founded a1 elevation of +6 to +8 feet (NGVD). In localized areas were bedroc below these elevations, the footing can either be lowered or the soil b the foundation removed to bedrock and filled with structural concrete. the south end of the seawall, the footing should be stepped down with bedrock surface. It is estimated that bedrock exposed near the surface at the face of seawall will erode at an average rate of 4 inch or less per year or abo feet in 50 years. It is recommended that the footing key for the sea extend into bedrock a minimum depth of 4 feet below the footing leve to an elevation of approximately +2 to +4 feet. It is estimated that south end where bedrock is below the normal beach level, erosion wil more eposodic and should occur only during maximum design storm wave conditions. In this area, it is recommended the key exten minimum of 2 feet into bedrock. It is further recommended that a< erosion along the front of the wall be monitored on a yearly basis. appears that erosion is occurring at a faster rate in some areas, it ma: necessary to place riprap along the toe of the wall at some future c The riprap should be designed and placed such that it is generally below the normal beach level. Reinforced Concrete Seawall Drain Based on measurements during the past six months, the existing grc water level along Carlsbad Boulevard appears to be relatively stable a -5- Project No. 542681-PD04 elevation of approximately +12 to +13 feet (NGVD). Seepage is also served along the bedrock surface at the toe of the bluff at an approx elevation of +8 to +10 feet. After construction of the seawall, it is a ipated that the ground water level at Carlsbad Boulevard may raise sei feet. For our analyses, we have assumed a maximum ground water vation along Carlsbad Boulevard of +18 feet. For this condition, recommend that the drain pipe behind the wall have a minimum diamett 4 inches and be located at an elevation of +10 feet. Weep holes thr the wall should be spaced at 10 feet on center. Reinforced Concrete Seawall Lateral Earth Pressures The proposed seawall will have a minimum 10 feet wide level walk behind the wall at an elevation of +17 feet. The natural bluff behind walk slopes up at an inclination of approximately 1$:1 (horizontal to v1 cal). It is recommended that the pressures for level backfill above water table (above elevation +10 feet), as presented in the Design &IC randum, be used for design. The 13:l slope should not have any sigi cant influence on the seawall above an elevation of approximately +6 f It is therefore recommended that a lateral pressure of 80 pcf (soil water) be used-below the water table from elevation +10 down to eleva +6 feet. Below an elevation of +6, it is recommended that due to effect of the 13 to 1 slopes, the lateral pressure be increased to 95 pcf ADDITIONAL COASTAL ENGINEERING INFORMATION Based on additional geotechnical information and discussions with perso: from the California Department of Boating and Waterways, we have rev certain coastal engineering design criteria.

DESCRIPTION OF THE PROJECT For this study, we have discussed the project with City of Carlsbad SI and we have been provided with .copies of the Feasibility Study prepa: by Woodward-Clyde Consultants, dated November 1984 and the Draft E vironmental Report prepared by Westec Services, Inc., dated March 191 We have also been provided with a copy of portions of a report entit: "Coastal Storm Drain Study, 'I prepared by Wilson Engineering, dated As 1984 and Sheets 8-11 of Drawing No. 159-9 for the Water Syst Improvements - Carlsbad Boulevard South, prepared by Enginec ing-Science, Inc. , dated December 15, 1970. We understand that the proposed project will include a seawall along t toe of the existing bluff, improvement of existing beach access ways, a the possible addition of one or more new stairways from the top of 1 bluff to the beach and new lateral access ways. The overall projc extends along the beach for a distance of approximately 4,400 fec Existing public beach access stairways, which lead down to the beach frl the top of the bluff, are located at Tamarack Avenue at the south end a Cherry Avenue near the middle of the project. Existing vehicular bea access ramps are located at Tamarack Avenue at the south end and Pi Avenue at the north end of the project. A public restroom facility located at Tamarack Avenue. Existing drain pipes are located upon t bluff at many locations. Many of the pipes lead down from storm drai and man-holes located along Carlsbad Boulevard and empty either on t B -3 Project No. 542681-CT03 bluff or at the toe of the bluff. It is our understanding that these p are to be relocated and surface water runoff collected and diverted z from the bluffs. The location and general limits of the project are SI- on the Site Plan (Figure No. 1 of the Design Memorandum). FIELD AND LABORATORY INVESTIGATIONS Our field investigation included making a visual geologic reconnaissanc the existing surface conditions, making beach profiles at approximate feet intervals along the project alignment, obtaining disturbed sample beach sand and cobbles, making three test borings on January 31, 1 obtaining representative soil samples from and installing well points in test boring. The test borings were advanced to depths ranging from to 43 feet. The drilling was performed, under the direction of a geolc from our firm, using an &inch diameter hollow stem auger truck mou rig. The location of each test boring and the elevation of the grc surface at each location were estimated by reference to the Water Sy Improvement drawings dated December 15, 1970, as well as the topographic information. shown on Figure No. 1 of the Design Rlemorandum. The approximate locations of the test borings A Key to Logs is presented on Figure B-1. Final logs of the test box are presented as Figures B-2 through B-6. The descriptions on the are based on field logs, sample inspection, and laboratory test results. Samples of the subsurface materials were obtained from the test boz using a modified California drive sampler (2-inch inside diameter 23-inch outside diameter) with thin brass liners. The sampler generally driven 18 inches into the material at the bottom of the hole 140-pound hammer falling 30 inches; thin metal liner tubes containing sample were removed from the sampler, sealed to preserve the na moisture content of the sample, and returned to the laboratory for amination and testing. B -4 Project No. 542681-CT03 The materials observed in the test borings were visually classified : evaluated with respect to strength, swelling, and compressibility char teristics; dry density; and moisture content. The classifications wc substantiated by performing grain size analyses on representative samp of the soils. Fill suitability tests, including compaction tests and dir shear tests, were performed on samples of the probable fill soils. The strength of the soils was evaluated by performing unconfined c( pression tests and direct shear tests on selected samples, and by cc sidering the density ana moisture content of the samples and the per tration resistance of the sampler. Results of the laboratory tests on dr: samples are shown with sampler penetration resistance at the correspondj sample locations on the logs and on Figures B-7 through B-16. I suitability tests are presented on Figure B-17. The results of p resistivity and water soluble sulfates tests are included as an attachmt from Clarkson Laboratory and Supply, Inc. Grain size distribution cur7 for the beach sands are presented on Figure B-10. The well installations generally consisted of an approximate 4'-9" long w screen placed near the bottom of the test boring and surrounded with N 20 sand. A solid riser pipe was extended to the surface and the hc backfilled with native soil. A locked cap was installed and the riser pj concreted-in at the top. GENERAL SITE CONDITIONS Geologic Setting The shoreline along Carlsbad Beach State Park, like much of the coastli along San Diego County, is backed by low coastal bluffs. The bluffs E backed by a broad, low relief coastal plain that generally extends seve tens of miles inland. Agua Hedionda Lagoon and Buena Vista Lagoon a two lagoons located immediately south and about 3 mile north, respective1 of Carlsbad State Beach. The lagoons generally act as "sediment traps B -5 Project No. 542681-CT03 as sand and sediment are largely discharged from the lagoons only dur periods of sustained, high runoff. Longshore transport of sand in littoral zone along this stretch of coastline is predominantly to the sou In order to maintain circulation and tidal action within Agua Hediol Lagoon, the entrance to the lagoon is periodically dredged. The sedim dredged from the lagoon is distributed hydraulically dong the beach a south of the lagoon inlet. Geologic Units and Erosion Characteristics The coastal bluffs backing the state beach area are underlain by Eocc sandstone of the Santiago Formation; the sandstone is typically exposed a low ledge along portions of the toe of the coastal bluff. The Santi: Formation is overlain by Pleistocene terrace deposits which are expo: along the face of the bluffs. The Pleistocene sediments were deposil upon a wave-cut platform (marine terrace) that was cut during a hj stand of sea level estimated at about 85,000 to 120,000 years ago. I' contact between the two geologic units generally varies in elevation alo the toe of the bluff from +6 to i12 feet and dips down to as low as -4 ft at the south end of the study area. The Santiago Formation consists of greenish grey clayey sandstone; t sediment comprising this formation is indurated and is generally much mc resistant to erosion than the Pleistocene sand. The upper bluffs i comprised of friable, fine- to coarse-grained sand. These deposits a typically weakly cemented, and are not capable of standing for long pel ods as vertical exposures over several feet in height. Steep faces erod into the Pleistocefie deposits are only marginally stable, and quickly slou back to a less steep slope inclination. The Pleistocene deposits are a1 relatively easily eroded by surface water runoff. Many relatively de gullies and small ravines have been partially filled with material dump from the bluff top. B -6 Project No. 542681-CT03 Geologic Structure Local bedding attitudes within the Santiago Formation could not be termined from the current exposures. The regional dip of the Santi Formation is generally to the northeast at inclinations typically less than degrees. lower sandy portion is highly cross-bedded. geologic units locally slopes seaward at several degrees. The presence of fractures, joints or faults may greatly accelerate the wj erosion process in the coastal environment. The Pleistocene terrace depl its are generally not a highly fractured or jointed unit; no faults WI observed, nor have any faults been mapped that displace the mar terrace. The Santiago Formation, however, is typically jointed a fractured to varying degrees; many northeast-trending fractures and SIT faults commonly cut the ‘Eocene bedrock. At other nearby locations alo the coast, such features as surge channels and sea caves are commor formed by wave action scouring the sedimentary rock adjacent to faults fractures. Along the study area, bluff erosion does not appear to greatly influenced by these features. Bedding within the Pleistocene deposits is nearly horizontal; The contact between the Seismicity and Faulting The faults within the study area do not displace the wave-cut terrace a are overlain by Pleistocene deposits, indicating that movement has r occurred during the past at least 85,000 and possibly 120,000 years. The nearest potential earthquake sources is the offshore continuation the Rose Canyon Fault zone, mapped about 3 miles west of the study are More distant earthquake sources include the Elsinore Fault zone, mapp about 25 miles to the northeast, and the Coronado Banks Fault zon approximately 20 miles to the west. Many historic moderate earthquak have occurred on the Elsinore Fault, whereas no earthquakes of magnitul greater than 4.0 have been recorded on the Rose Canyon. In genere B -7 Project No. 542681-CT03 although the historic seismicity record of Southern California is relati. short, the San Diego area has historically been recognized as an ares relatively low seismic activity. Although no specific seismic evaluation performed for this study it appears to be reasonable to estimate that largest earthquake-induced ground acceleration at the site with an aver recurrence of 50 years is about 0.15g. Landslides No existing landslides were observed on the site during our investigati nor were any noted on published geologic maps used for our study. ' terrace sands are subject to sloughing and blockfalls where the bluff been undercut by wave action or .human digging. Numerous burrows h also been dug into the bluffs by ground squirrels. These erosion p' cesses result in mass wasting deposits which occur along the coastal bl on slopes of the Pleistocene terrace unit. These deposits are usus composed of unsorted mixtures of locally derived materials and gener& range from a few inches to several feet in thickness. mass wasting accumulate on the upper beach at the toe of the bluff z are subsequently eroded and disposed by wave action and littoral drift. Deposits formed Sur face Conditions North of Agua Hedionda Lagoon , Carlsbad Boulevard extends genera parallel to and along the top of the bluff above Carlsbad State Beac The boulevard is generally set back from the bluff edge distances varyi between as little as 2 feet to as much as 50 feet. Public parking available along the west side of Carlsbad Avenue between Tamarack a Cherry Avenue. At the intersection of Pine Avenue, Carlsbad Bouleva turns inland away from the coastal bluffs. At this point, Ocean Strt continues northerly adjacent to the bluff top. Parking is also availal along the west side of Ocean Street. Private homes have been built do the bluff north of Oak Avenue. B -8 Project No. 542681-CT03 At the south end of the study area, two parallel rock jetties ext seaward about 200 feet from the mouth of Agua Iledionda Lagoon. A pa public parking area is located north of the jetties and generally south Tamarack Avenue. The parking area includes approximately 2 acres anc located generally west of and below Carlsbad Boulevard along the toe the bluff. Grading for the parking area apparently consisted of plac fill from the back beach area, adjacent to the toe of the bluff, out to n the end of the jetties. This resulted in a relatively level pad several 1 above the elevation of the beach. A new concrete block wall has b constructed along the toe of the bluff (east side of parking lot) and sc rock riprap has been placed along the seaward (west) limits of parking area as a means of temporary slope protection. The rip] generally consists of a single layer of 2 to 4 ton stone placed upor cobble berm. A local park area, which extends along a portion of the top of the bluf consists of a landscaped picnic area with a concrete walkway leadi generally through the picnic area and along the top of the bluff. Ti park extends from south of Tamarack Avenue north to approximatt Cherry Avenue. The landscaping includes trees, grassy area, pic. tables and a low wooden railing along the top of the bluff. A put: restroom is located near the top of the bluff near Tamarack Aveni Public beach access stairways, which lead down from the top of the blu are located at the restroom facility (Tamarack Avenue) and across fr- Cherry Avenue. A vehicular beach access ramp is also located near t north end of the park at Ocean Street. Beach access is also available the parking lot at the south end of the park. The public access at Chc ry Avenue consists of a stairway elevated several feet above the bluff columns and pier foundations. The stairway was originally located adjact to a second public restroom located at beach level. During the win storms of 1983, this restroom, and the lower stairway landing were heav damaged by storm waves and were subsequently demolished and remove Portions of the concrete-slab foundations below the old restroom a1 remain in place on the beach. The lower stairway landing has be B-9 Project No. 542681-CT03 repaired and the stairs replaced with a wooden structure. A portion the natural slope below the upper landing has been rebuilt with stacl sand-filled sacks. Drain pipes are located upon the bluff at many locations. pipes lead down from storm drains and man-holes located along Carlsl Boulevard to concrete box culverts built at the toe of the bluff. Ot pipes collect surface water run off from along Carlsbad Boulevard E adjacent areas. Several of Gullies and deep ravines are developed nearly continuously along the f, of the bluff. Many of the wider, more extensively gullied areas extc from the beach level up to the top of the bluff. The upper portions many of the deeper gullies and ravines have been partially filled w material dumped from the top of the bluff. The materials used for 1 dumped fill include concrete and asphalt rubble. Two areas of the upper bluff adjacent to Carlsbad Avenue have requir fairly extensive temporary slope repair. This slope rebuilding H required in 1983 along two approximately 50 foot wide stretches of 1 bluffs west of Walnut Avenue and Acacia Avenue. This temporary slo repair generally consisted of rebuilding the slope by placing a fill slo down to the level of the beach, and using riprap to protect the toe of t fill slope. Jute netting was laid upon the slope to retard surface wal erosion. Much of the bluff face is barren; vegetation along the bluff consists scattered patches of iceplant and native grasses with locally dense stan of bamboo. The beach along the base of the bluffs is typically about 100 to 150 fe wide. Abundant cobbles form a low berm several tens of feet wide alo the back edge of the beach. Seasonal variations in longshore drift, wa height and wave frequency result in varying beach levels and volumes sand. B-IO Project No. 542681-CT03 Subsurface Soil Conditions The subsurface soils as encountered in the three borings drilled along top of the bluff and as observed in the exposures along the face of 1 bluff generally consist of approximately 2 to 5 feet of moderately comp moist, brown, silty sand fill underlain by terrace deposits composed medium dense to very dense silty sand and poorly graded fine to medi sands. Within the terrace deposits locally thin cemented zone and grav up to 2 inches across were also observed. Below the terrace deposits, approximately 7 to 15 feet above National Geodetical Vertical Dat (NGVD) , the Santiago Formation was encountered. The Santiago Format in the area is composed of indurated and well cemented sandstone. The beach at Carlsbad State Beach has a moderately varying tern consisting of clean fine beach sands, non-uniformly dispersed cobblc boulders, and exposed bedrock. From the toe of the bluffs extendi seaward, the surficial geology is basically exposed cobbles and boulders an elevated beach terrace followed by a descending slope covered w additional cobbles thinning toward sparse cobbles and gravels embedded clean beach sand. The cobbles range in size from approximately 3 tc inches. This is followed by a gentle sloping surf zone of clean grad€ fine beach sands. During the winter the beach material generally appes to have a thickness of 2 to 6 feet with localized thicker areas. At appro imately 150 to 200 feet and beyond, projecting bedrock is exposed in t surf zone. Soil Characteristics The terrace materials generally consist of poorly graded fine to medi sands with approximately 5 to 10 percent fines (material passing a No. 2 sieve size). The dry density generally ranges from approximately 95 115 pcf with a mean Value of 105 pcf with an average moisture content of percent. The normalized sampler penetration values ranged from appro: B-11 Project No. 542681-CT03 mately 15 to over 60 blows per foot with a mean value of approximately blows per foot. The mean friction angle for this material is approximai 37O with a standard deviation of approximately t440. The Santiago Formation materials generally consist of a cemented silty I sand with about 15 to 25 percent fines. The average dry density : moisture content of a limited number of samples is approximately 122 and 13 percent, respectively. The sampler penetration values w generally over 100 blows per foot and the unconfined compression val ranged from approximately 10,700 psf to 18,500 psf. The beach materials at the time of our study generally consisted of clc fine sands with rounded and elongated gravel and cobble. The be: sands typically have a 100 percent material finer than a No. 30 sieve s (0.59 mm) and zero percent finer than a No. 200 sieve size (0.074 mrr The gravel and cobbles generally range from approximate 1 to 8 inches average diameter. The gravel and cobble are generally higher on t beach and decrease in size as you move out from the toe of the bluff. Ground Water A perched ground water table typically occurs at the contact between t Santiago Formation and the Pleistocene deposits. This condition is comm along the North County coastline and has been recognized as a contribL ing factor to bluff erosion. The source of the ground water is thought to be primarily surface wat introduced locally as rainfall and irrigation that percolates into the perm able terrace sands. When the ground water reaches the relative impermeable Santiago Formation, it flows laterally along the seaward-slopir contact until it reaches the bluff face. A line of vegetation common grows at this point on the bluff. Prominent ground water seepage W~ observed along the toe of the bluffs at many locations within the stuc area. B-12 Project No. 542681-CT03 Ground water was encountered in each test boring and was obser seeping out at the toe of the bluff along the contact between the terr sands and sandstone formations. Periodic water elevation measureme made in the test boring wells are presented below: Test Boring 1 Test Boring 2 Test Boring 3 Date (Tamarack Ave. ) (Cherry Ave. 1 (Pine Ave. ) 01-31-86 +11.5 +12.5 +11.0 02 -0 6-8 6 +12.1 +12.7 +ll. 6 02 -2 1-8 6 +12.3 +12 e 9 +11.8 03-03-8 6- +12.2 +12.8 +11.7 03-12-86 +12.3 +13.0 +11.8 03-20-86 +12.3 +13.0 +ll .8 * Elevations are NGVD It should be anticipated that minor variations will occur in the grou water levels, depending on the amount of rain fall and land irrigation the area. DISCUSSIONS, CONCLUSIONS, AND RECOMMENDATIONS The discussions, conclusions, and recommendations presented in t. report are based on the information provided to us, results of our fil and laboratory studies, analyses, and professional judgment. Potential Geologic Hazards Faulting and Ground Shaking No active faults were identified on the site and the closest active fa zones are the Elsinore Fault approximately 25 miles from the site and 1 B-13 Project No. 542681-CT03 Coronado Banks Fault approximately 20 miles from the site. No detai seismic evaluation of the site has been made; however, it is recommc that a minimum ground acceleration of 0.15g be used for design of ' seawall. Liquefaction The terrace sands are generally dense to very dense and the sandstone very dense and cemented. The water table is generally confined to a tl zone (5 to 10 feet thick) above the contact between the two formations. is our opinion that there is a low probability of liquefaction occurring these materials at the subject site. Site Grading Excavation and Material Characteristics It is anticipated that some cutting and filling will be required to constri the proposed seawall and associated facilities. The terrace sand 2 relatively friable and should be relatively easy to excavate. These ma' rials should also 'provide a suitable select granular fill. The sandstone the Santiago Formation are relatively hard and cemented and may requj special equipment to excavate; however it is not anticipated that a blasting will be required. Excavation of the sandstone may also result some oversize material that may require crushing or breaking up for use fills. Temporary Cut Slopes Our analyses indicate that temporary cuts in the undisturbed terrace san should have a safety factor of 1.2 or greater against a deep slide f inclinations of 1:1 or flatter up to approximately 20 feet in height. It anticipated that the sandstone should stand at near vertical inclinations up to 10 feet in height. These materials are subject to localized sloughi B-14 Project No. 542681-CT03 and blockfalls and should be observed during construction. rnent, shoring or flatting of slopes may be required in some areas. Special trei Natural Slopes In general, the natural slopes comprising the coastal bluffs appear to grossly stable in their present condition. However, the sandy, frial terrace deposits, when undercut and oversteepened by wave action, i only marginally stable at relatively steep slope inclinations. Experier with this geologic unit in the subject area and at other locations along t coast has shown that once slopes are oversteepened, additional' surf: sloughing andlor relatively shallow slope failures are likely to continue occur within and adjacent to the undercut area until more stable slo inclinations are reached. Factors that could influence slope failures wit1 such potentially unstable areas include heavy rainfall, ground wat seepage, earthquakes e and additional erosion by high wave action. Re1 tively minor slope failures or blockfalls could represent a potential haza to beach users. Cut and Fill Slopes We have performed stability analyses for anticipated cut and fill slopes 1 the Jaubu method using the following strength parameters for the terra materials: 0 - 37*, C = 100 psf. The results of the analyses indicate th the slopes with maximum inclinations of 1i:l (horizontal to vertical) ai maximum heights of 30 feet have calculated factors of safety in excess 1.5 for static conditions, and in excess of 1.2 for dynamic condition Assuming a horizontal coefficient of ground acceleration of 0.15g. Stabili analyses require using parameters selected from a range of possible v: ues. There is a finite possibility that slopes having calculated factors safety, as indicated, could become unstable. In our opinion, the probabj ity of slopes becoming unstable under the assumed conditions is low. B-15 Project No. 542681-CT03 Fill slopes, especially those constructed at inclinations steeper than 2 are particularly susceptible to shallow slope sloughing in periods of ra fall, heavy irrigation, and/or upslope surface runoff. Periodic sL maintenance may be required, including rebuilding the outer 13 to 4 f of the slope. Sloughing of fill slopes can be reduced by overbuilding least 3 feet and cutting back to the desired slope. To a lesser exte: sloughing can be reduced by backrolling slopes at frequent intervals. a minimum, we recommend that fill slopes be trackwalked so that a do track covers the surfaces at least twice. We recommend that cut and slopes be planted, drained, and maintained. Fill Compaction It is recommended that structural fills be compacted to a minimum relati compaction of 92 percent in accordance with ASTM Test Designat; 1557-78. Structural fills should be observed and tested . by 1 geotechnical engineer. Drainage A perched ground water table is present along the contact between 1 terrace sands and underlying sandstone which results in water seepage the toe of the bluff. It is recommended that all retaining structures provided with back drains to intercept and control this seepage. It further recommended that the back drain be placed at an elevation approximately +10 to +12 feet (NGVD) behind the proposed seawall. It is also recommended that existing drains on the bluff generally abandoned and that a new storm drain system be designed and construcl to collect and divert runoff away from the bluff. The new facilities shol be designed such that surface drainage waters are directed away from t bluff top. B-16 Project No. 542681-CT03 The site is located along the edge of the Pacific Ocean and is subjec inundation from tides and the action of waves. The contractor will hav take special measures to protect his work and to keep construction a. free from surface, subsurface and ocean water. Foundations It is recommended that the foundations for the seawall and beach acc stairways be founded in the dense sandstone of the Santiago formatic The foundations should have a minimum width of 2 feet and extent minimum of 2 feet into the sandstone. Where foundations are exposed scour from wave action, the foundations should either be protected by stone or extend below the design scour depth. It is recommended that for foundations bearing in sandstone, a maxim allowable soil bearing pressure of 8,000 psf be used for design. T value may be increased by up to one third for loads that include wind seismic forces. AI1 loose or disturbed material should be cleaned fx foundation excavations and foundations should bear on clean undisturt sands tone. It is estimated that settlements under anticipated loads will be less thar inch. Retaining Walls It is anticipated that the seawall may be designed as a cantilever retainii structure along the toe of the existing bluff. Two possible conditions a considered, one with a level backfill and walkway behind the Wall and 0' with an average slope inclination of approximately 13: 1 (horizontal vertical) and no walkway behind the wall. For these conditions, it recommended that the following equivalent fluid lateral earth Pressures t used for design : B-17 Project No. 542681-CT03 Level Backfill - 30 pcf (Static) 15 pcf (Seismic-inverted) 1i:l Slope - 60 pcf (Static) 30 pcf (Seismic-inverted) It is further recommended that an average total unit weight and submerl unit weight of 115 and 55 pcf be used for the backfill and terrace sands It is recommended that the retaining walls be provided with a back dr to limit the ground water level to elevation +10 to +12 feet (NGVD). Wa pressures should be considered to. act on the wall below this elevation. To resist lateral pressures, it is recommended that for foundations in 1 sandstone a uniform passive pressure of 2,000 psf and a friction coefficic of 0.3 be used for design. UNCERTAINTY AND LIMITATIONS We have observed only a very small portion of the pertinent soil a ground water conditions. The recommendations made herein are based the assumption that soil conditions do not deviate appreciably from thc found during our field investigation. We recommend that Woodward-Cly Consultants observe the site grading and foundation excavations to veri that site conditions are as anticipated or to provide revised recommend tions if necessary. If variations or undesirable geotechnical conditions a encountered during construction, we should be consulted for furth recommendations. This report is intended for design purposes only and may not be sufficic to prepare an accurate bid. B-18 Project No. 542681-CT03 California, including San Diego, is an area of high seismic risk. It generally considered economically unfeasible to build a totally earl quake-resistant project; it is, therefore, possible that a large or ne81 earthquake could cause damage at the site. Geotechnical engineering and the geologic sciences are characterized uncertainty. Professional judgements presented herein are based partly our understanding of the proposed construction, and partly on our gene experience. Our engineering work and judgements rendered meet currf professional standards; we do not guarantee the performance of the pro$ in any respect. Inspection services allow the testing of only a small percentage of the : placed at the site. Contractual arrangements with the grading contracl should contain the provision that he is responsible for excavating, placin and compacting fill in accordance with project specifications. Inspecti by the geotechnical engineer during grading should not relieve the gradi contractor of his primary responsibility to perform all work in accordar with the specifications. This firm does not practice or consult in the field of safety engineerin We do not direct the contractor's operations, and we can not be respo sible for the safety of personnel other than our own on the site; t safety of others is the responsibility of the contractor. The contract should notify the owner if he considers any of the recommended actio presented herein to be unsafe.
