The purpose of our investigation was to perform subsurface investigation to evaluate subsurface conditions for the proposed construction. Two different wall alternates were considered, a segmental concrete wall system and a conventional concrete wall. Conclusions and recommendations relative to the site grading, retaining wall design, temporary excavations, and type of cement for construction are presented herein. PROPOSED CONSTRUCTION We understand that the proposed construction will consist of removal of an existing concrete rubble wall and construction of a new concrete wall with a maximum height of about 6 feet. SCOPE OF SERVICES The scope of services provided during the course of this investigation included: a. Subsurface exploration consisting of two auger borings and a test pit, b. Logging and sampling of the borings and test pit and collection of soil samples for laboratory testing, Bagahi Engineering Inc. W. Frank Tran Project: Retaining Wall ' Project No: 194y- 156-00 / November 14, 2008 Page 5 ' C. Laboratory testing of soil samples representative of subsurface conditions encountered in the borings, ' d. Geotechnical analysis of field and laboratory data to develop site stratigraphy and provide a basis for our conclusions and recommendations, e. Comparison of two possible likely wall alternates, Preparation of this report presenting our findings, conclusions and recommendations. SITE DESCRIPTION The project site is along the south side of Cove street facing Newport Bay. An existing concrete rubble wall, about 6 feet in height, is currently located in this area. The wall is in a deteriorated condition with one portion blown out exposing the backfill. A test ' pit at the toe of the wall revealed a footing under the existing wall embedded about 18 inches below the beach. Toe of the wall is along the shoreline and appears to be about 2 feet above sea level, based on water markings on nearby structures. SUBSURFACE INVESTIGATION SITE EXPLORATION Subsurface conditions for this study were explored by drilling two auger borings to a maximum depth of 9 feet and a test pit at the toe of the wall. The approximate locations of the borings are shown on the Plot Plan in Appendix A. t Sampling included collection of bulk samples from cuttings derived during drilling, and ring samples. Relatively undisturbed samples (rings) were obtained using a modified hand sampler. The soil samples were retained in a series of brass rings each ' having an inside diameter of 2.41 inches and height of 1.0 inch. These rings were placed in close- fitting, moisture-tight containers for shipment to the laboratory for testing. 1 Bagahi Engineering Inc. Mr. Frank Tran Project: Retaining Wall Project No: 194y- 156 -00 /November 14, 2008 Page 6 Continuous logs of the subsurface conditions, as encountered in the borings, were recorded at the time of the drilling. A summary of these conditions is given in the log of borings in Appendix A. Test borings were located in the field by pacing from known landmarks. Boring locations as shown are therefore within the accuracy of such measurement. Subsequent to logging and sampling, the test holes were back611ed and tamped utilizing the soils excavated LABORATORY TESTING Laboratory tests on both bulk and split spoon samples of the on -site soils were performed as part of this investigation to determine engineering properties of the subsurface materials. The details of the laboratory testing program and the test results are presented in Appendix B. FINDINGS SUBSURFACE CONDITIONS Based on the results of this investigation and laboratory testing, the subsurface materials at near the toe of the existing wall consist of light brown beach sand. At the time of drilling groundwater was encountered at about 2 feet below the surface. Depth to groundwater is however tidal and shallower groundwater conditions are likely. Backfill behind the wall consists of light brown fine sand with some shell fragments. FAULTING SEISMICITY AND LIQUEFACTION POTENTIAL The site is located in an area that is subject to moderate to strong earthquake ground shaking. The site is located in close proximity of Newport- Inglewood fault. Newport- Inglewood fault fits the Type —B category for Seismic Source Type based upon the slip rate information provided on the California Division of Mines and Geology (CDMG) fault parameters table. The site is not mapped as prone to liquefaction by State of California Seismic Hazard Zones Map. Bagahi Engineering Inc. Mr. Frank Tran Project: Retaining Wall Project No: 194y- 156 -001 November 14, 2008 Page 7 CONCLUSIONS AND RECOMMENDATIONS WALL TYPES From a geotechnical engineering standpoint, it is our opinion that the proposed wall construction at the subject site would be feasible and would not impact adjacent properties provided the recommendations and conclusions presented herein are incorporated into the project design, plans and specifications, and implemented during construction. Two wall alternates are considered. A conventional concrete wall, most likely a masonry block wall and a segmental geogrid wall. The two alternates are illustrated on the wall cross section in Figure 1. As can be seen from Figure 1, it is likely that temporary excavation for installation of geogrid wall can result in a deeper excavation into Cove street as compared to conventional retaining wall. If excavations can not extend into Cove Street, then shoring along Cove Street would be necessary. The lengths of geogrids as shown are however an estimate and final lengths by the wall designer could be shorter, making the backcut closer to that of conventional wall. SITE PREPARATION AND GRADING 1. Clearing and Stripping All existing vegetation, debris, concrete, utilities or other deleterious substances within the proposed improvement areas and extending to 2 feet beyond these areas or to property he should be removed. Debris and rubble from the clearing operations should be removed from the site. Any existing disturbed loose soils should be removed and replaced with properly compacted fill material. Depressions resukmg from the removal of unsuitable materials, which extend below finished site grades, should be backfilled with properly compacted fill. 2. Sabgrade Preparation After removal of existing wall, the subgrade shall be scarified a minimum of six inches, moisture conditioned and proofrolled.

All exposed surfaces in the excavations should be observed and approved by this office prior to backfilling. Any localized dry or loose subgrade conditions observed at excavation levels should be excavated and backfilled with compacted granular fill. No excavation shall extend below the bottom of foundation of adjacent structures unless special precautions such as shoring are taken to protect the adjacent structures as discussed under "Temporary Excavations." CONCRETE RETAINING WALL (ALTERNATE I) First ahemate is a conventional masonary block or cast -in -place concrete wall. Retaining wall planned should be adequately designed to resist the lateral soil pressures and the anticipated construction loadings and service conditions. The earth pressure acting on retaining walls depends primarily on the allowable wall movement, type of backfill materials, backfill slopes, wall inclination, surcharge loads, and any hydrostatic pressure. Recommended lateral earth pressure criteria for vertical walls with level backfill, no hydrostatic pressure and no surcharge loading, are shown below: EQUIVALENT FLUID PRESSURE (pcf) SOIL TYPE EARTH PRESSURE Active At -Rest On -site sandy soils 35 50 Import clean sands 35 50 ' The active earth pressure values provided may be used for cantilevered retaining walls. Restrained retaining walls that are not free to rotate at top, should be designed using the at -rest earth pressure values. Depending on whether the wall is restrained (rigid) or ' unrestrained (free to deflect), an additional uniform lateral pressure equal to 50 or 33 percent, respectively, of the anticipated maximum surcharge load located within a distance equal to the height of the wall should be used in the design. 1 Import soils used for retaining wall backfill should be predominantly granular, with an expansion index of less than 20, and free of organic material and rock in excess of four Bagahi Engineering Inc. ' Mr. Frank Tran Project: Retaining Wall ' Project No: 194y- 156 -00 / November 14, 2008 Page 10 ' inches maximum dimension. Retaining wall foundation should be designed in accordance with the recommendations under "Foundation and Slab Recommendations ". Walls should be adequately drained to prevent build -up of hydrostatic pressures. Wall drains should be directed to an approved outlet. As a minimum, the wall may be drained by placing a 4-inch perforated PVC Schedule 40 pipe or approved equivalent, with perforation placed down behind the base of the wall. The pipe should be surrounded by 3/4 -inch crushed rock at a rate of not less than one cubic foot per linear foot of pipe surrounded in turn by a geofabric such as Mirafi 140NC or equivalent. The drain shall be connected to a solid PVC pipe Schedule 40 or equivalent leading to an approved outlet. All wall backfill should be mechanically compacted to a minimum of 90 percent relative compaction in accordance with ASTM D- 1557 -78. If a limited area exists behind the wall, geotextile drain mats such as Mirafi Miradrain or equivalent, can be used in lieu of a conventional pipe and gravel drainage system The drain mats should extend the full height and lengths of the walls, and the filter fabric side of the drain mats should be placed against the backcuts. The perforated pipe drain lines placed at the bottom of the drain mats should consist of 4-inch minimum diameter PVC Schedule 40 or ABS SDR -35. The filter fabric on the drain mats should be peeled back and then wrapped around the drain line. ' If imported pea gravel or crushed rock is used for backfill, the gravel should be placed in approximately 2 to 3 foot -thick lifts, thoroughly wetted but not flooded, and then mechanically tamped or vibrated into place. A representative of the project t geotechnical consultant should observe the backfill procedures and probe the backfill to determine that an adequate degree of compaction is achieved. To mitigate the potential for the direct infiltration of surface water into the backfill, the backfill should be capped with at least 24 inches of silty sandy soil. A filter fabric such as Mirafi 140N or equivalent, should be placed between the soil and the imported gravel or rock to prevent fines from penetrating into the backfill. Proper surface drainage should be provided along the top of walls. Wall subdrains should outlet separately and not be combined with area drains. Bagahi Engineering Inc. Mr. Frank Tran ' Project: Retaining Wall Project No: 194y- 156-00 / November 14, 2008 Page 11 I, SEGMENTAL CONCRETE WALL (ALTERNATE 2) I' 1. General I' This wall consists of segmental concrete facing blocks that are connected to intermittent horizontal geogrids placed behind the facing. The proposed maximum exposed wall height for the site is about 6 feet. 2. Excavations Excavations for installation of the new wall should be laid back no deeper than 1:1 gradient or properly shored. Much of the temporary back -cut would extend into Cove Street unless it is properly shored (see Figure 1). This is further discussed in Temporary Excavation Section. The above criteria are intended as general guideline only The Geotechnical Consultant makes no warranties either express or implied as to the stability of temporary construction slopes. Soil conditions may vary locally and therefore site - specific evaluation of temporary excavation slopes will be required. 3. Wall Erection As blocks are installed and backfill material is placed behind the blocks, the blocks shall be maintained in position such that the overall vertical tolerance of the wall (top to bottom) shall not exceed one inch per 5 feet of the wall height. A wall batter of IH:8Vis considered. Reinforcement elements shall be placed normal to the face of the wall and connected structurally to the wall facing elements. Prior to placement of the reinforcing elements, backfill shall be compacted in accordance with these specifications. 4. Backfill Placement and Compaction Backfili placement shall closely follow erection of each course of blocks. Backfill shalt be placed in such a manner as to avoid any damage or disturbance of the wall material or misalignment of the facing. Any wall materials which become damaged during backfill placement shall be removed and replaced at contractor's expense. Any misalignment or distortion of the wall facing due to placement of backfill outside the limits of this specification Bagahi Engineering Inc. . Mr. Frank Tran .Project: Retaining Wall Project No: 194y- 156 -00 /November 14, 2008 Page 12 shall be corrected by the contractor at his expense. At each reinforcement level, the backfill shall be placed to the level of the connection. Backfill placement near the facing shall assure that no voids exist directly beneath the reinforcing elements. Backfill shall be compacted to a minimum of 90 percent of the maximum density as determined by ASTM ➢:1557 (5 layer method). The moisture of the backfill material prior to and during compaction shall be uniformly distributed throughout each layer. Backfill material should have a placement moisture content within 2 percentage points of the optimum moisture content. The maximum lift thickness before compaction shall not exceed 8 inches. The contractor shall decrease this lift thickness, if necessary, to obtain the specified density. Compaction within 3 feet of the back face of the wall shall be achieved by at least three passes of a mechanical tamper, roller or vibratory system Fill placement adjacent to the backcut shall be benched to achieve a level surface for fill placement and compaction. At the end of each day's operation, the contractor shall slope the level of the backfill to direct runoff away from adjacent areas to enter the wall construction site. 5. Connection to Adjacent Stairway Wall A corner detail is necessary where proposed wall meets existing stairway wall . The corners must provide a positive connection such that the wall backfill material cannot spill out through the connection at any time during the design life of the wall. Furthermore, the corner must be constructed in such a manner that the wall can be constructed with the full geotexdite embedment lengths shown on the plans in the vicinity of the corner. 6. Wall Embedment Wall fkicing embedment shall be a minimum of 2 fleet below the lowest adjacent grade. In addition, wall embedment shall be at least a foot below any future toe erosion as a result of wave attacks from storm. Bagahi Engineering Inc. I Mr. Frank Tran ' Project: Retaining Wall Project No: 194y- 156 -00 / November 14, 2008 Page 13 ' 7. Back Drain I' Due to potential soaking of the wall in periods of storm activity, a drainage system composed of a blanket drain and a chimney drain shall be incorporated into the wall design as recommended by National Concrete Masonry ' Association. Such a system is illustrated in Figure 2. The blanket and chimney drains shall be composed of 3/4 —inch crushed rock or appropriate geocomposite such as MiradrauL The lower drain pipe shall be perforated PVC ' Schedule -40 pipe or equivalent, a minimum Of 4- inches in diameter and connected to solid PVC Shedule40 outlet pipe. 8. Wall Backfill Material ' The reinforced backfill material shall be free of debris and rock fragments and consist of non - expansive material such as silty sand. There shall be less than 5 percent by weight of particles greater than % inch, between 30 to 70 percent by ' weight passing No. 20 sieve and less than 10 percent passing No. 200 sieve. Maximum partical size shall be limited to '/. inch. Wall backfill material shall be approved by the Geotechnical Consultant prior to importing. 9. Soil Parameters Following soil parameters may be used in the wall design: Material Reinforced Retained Foundation Angle of friction 39 30 30 Cohesion (pst 0 0 0 Moist unit weight (pcl) 100 100 100 For seismic design a horizontal ground acceleration of at least 213 of the probabilistic ground motion of 0.4 g may be used with vertical acceleration of at least 2/3 of the horizontal acceleration.

Surface Drainage A ditch drain shall be provided along the top of the wall to catch any surface ' runoff from the backSll and direct it to storm drain. ' 11. Groundwater Shallow groundwater may be encountered in excavations for the wall foundation hereby requiring temporary dewatering. During our boring excavations, groundwater was encountered at a depth of about 2 feet below the ' toe of the wall. Depth to groundwater is however tidal, seasonal and variations from our observation is likely. 12. Segmental Wall Units Segmental wall units shall be composed of concrete with a minimum compressive strength of 3000 psi in 28 days. Units shall be securely interconnected using one inch diameter Schedule 80 pipe or equivalent per manufacturer's recommendation. Units shall be positively engaged to the units below. 13. Leveling Pad A leveling pad shall be provided at the bottom of the wall. Leveling pad should be a minimum of 6- inches thick and extend at least 6-indm beyond the toe and heel of lowermost unit. TYPE OF CEMENT A sulfate test was performed on a sample of near- surface sandy soils. The test results are presented in Appendix B and indicate low sulfate content. It is recommended that all concrete in contact with subgrade soils meet as a minimum the requirements of Table 19 -A4 of 1997 UBC for concrete exposed to at least negligible sulfate exposure. Exposure to marine air may require special concrete. A concrete expert shall be consulted for appropriate concrete mix design. Bagahi Engineering Inc. Mr. Frank Tran Project: Retaining Wall Project No: 194y- 156 -00 /November 14, 2008 Page 16 ' TEMPORARY EXCAVATIONS All excavations and shoring systems should meet the minimum requirements given in Article 6 of the State of California Occupational Safety and Health Standards. The contractor is solely responsible for the stability of temporary slopes and safety and maintenance of such excavations. Temporary excavations should be no steeper than 1:1 gradient (horizontal:vedical) or properly shored On -site soils are sandy and in a loose condition Near — surface soils in ' the upper 5 feet (behind the wall) are in a relatively dry condition and are subject to raveling and sloughing of cut slopes that could present in back-cuts flatter than 1:1 gradient. Excavations should be kept moist but not saturated and not allowed to dry to a significant degree i.e. formation of desiccation cracks prior to placement of Wckfill. Temporary excavations should be backfilled as soon as practical but not exceeding a few days. Excavations that extend below an imaginary plane inclined at 45 degrees below the edge of any nearby adjacent existing site facilities should be properly shored to maintain foundation support of the adjacent structure. Slope and excavation faces should be covered with plash sheets during rainfall periods to avoid saturation of the cut areas. The above criteria are intended as general guideline only. The Geotechnical Consultant makes no warranties either express or implied as to the stability of temporary constriction slopes. Soil conditions may vary locally and therefore site- specific evaluation of temporary slopes will be required. Soldier Pilo and Lagging Following soldier pile and lagging shoring recommendations may apply to excavations near along Cove Street unless approval can be obtained to extend the excavation into Cove Street. Soldier pile and lagging may be designed by a shoring engineer using an active lateral earth pressure of 20 pcf and a lateral resistance of 230 pcf which inchrdes the doubling effect for pole action Building and equipment surcharge should be added to the lateral earth pressure. A uniform surcharge pressure with depth shall be included in the shoring design to account for the presence of construction materials and equipment adjacent to the top of the shoring. This surcharge should include the localized effect of heavy equipment such as cranes or concrete trucks within about 15 feet of the top of shoring. Bagahi Engineering Inc. I Mr. Frank Tran ' Project: Retaining Wall Project No: 194y- 156-00 / November 14, 2008 Page 17 ' Installation of shoring by vibratory equipment shall not be utilized due to the high risk of damage to adjacent structures. Shoring may consist of steel "II" beams placed into drilled holes. The annulus of the " H" beam and boring shall be filled with concrete for ' embedded length and with two -sack slurry for the shored length with lagging. Concrete placement below groundwater shall be by tremie method. Temporary casing is expected in excavations in on -site sandy soils. After installing the shoring piles, slurry should be allowed to cure for at least seven ' days prior to excavating the basement. As the excavation progresses downward, lagging shall be installed between the beams The lagging shall be level with no significant gaps. The void between the back of lagging and the construction cut shall ' be infilled with sand slurry and is normally vibrated down by hammering the lagging. A structural engineer familiar with shoring design shall design shoring and lagging. ' The shoring may be designed into the permanent basement wall if designed properly by the structural engineer. Bagahi Engineering Inc. shall observe shoring installation to verify compliance with the project recommendations. It is recommended that the client perform photo documentation and survey monitoring prior to and during shoring installation, and until the basement walls are permanently internally braced and backfilled. Documentation should include shoring elements, control points and adjacent properties. It is the responsibility of the contractor to maintain safe working conditions and to notify Bagahi Engineering Inc. of potential problems so proper recommendations can be made. As a precaution, it is recommended that Bagahi Engineering Inc. shall observe all cuts, at the time of excavation. PLAN REVIEW Wall plans should be made available to us for review to verify conformance of these plans with the intent of the recommendations contained herein prior to permit application. Our review deals with general conformance of plans with our geotechnical recommendations and does not include review of accuracy of dimension, measurements, calculations, design or other professions inputs. Our review is not intended to evaluate an entire system of which a component is reviewed.

Moisture content tests were performed on bulk samples. Test results are presented in the boring logs. SULFATE ' A sulfate test was performed on a representative sample of the on -site soils. The laboratory standard used was California 417 A. The test results show a low sulfate ' content of less than 0.1 percent. ' DIRECT SHEAR Two direct shear tests were performed on samples of the near - surface soils. One test was ' performed as a relative undisturbed sample and the other test was performed on a remolded sample compacted to near 90 percent relative compaction. The apparatus used is in conformance with the requirements outlined in ASTM: D3080. Each test specimen, ' 2.4 inches in diameter and 1 -inch in height, was subjected to simple shear along a plane at mid - height after allowing time for pore pressure dissipation prior to application of shearing force. Each sample was saturated prior to shear under various nominal loads. The sample was sheared at a constant rate of strain of 0.05 inches per minute. Shearing of the specimen was continued until the shear stress became essentially constant, decreased or until a deformation of approximately 10 percent of original diameter had been reached. ' The post -peak shear stress values were plotted versus applied normal stress, and a best -fit ' straight line through the plotted points was drawn to determine the cohesion and the angle of the internal friction parameters. The direct shear test result is graphically presented in Direct Shear Test Plot. ' EXPANSION INDEX On site soils are granular and non - plastic with very low expansion potential. tBagahi Engineering Inc.
