Additionally, on April 21, 2008, the Community Development Commission of the City of San Bernardino ("Commission") approved and authorized the Interim Executive Director of the Redevelopment Agency of the City of San Bernardino ("Agency") to execute said Agreement by and between the Agency and the State of California. On April 24, 2008 and May 13, 2008, the Agreement was executed by the Agency and the Judicial Council of California Administrative Office of the Courts ("AOC") respectively. The Agreement stipulates the terms and conditions to sell, convey, and deliver to the AOC all the Agency's right, title, and interest in and to said property. One of the AOC's buyer contingencies states that within one (1) year after the effective date and prior to the close of escrow, the Agency shall relocate the existing sewer line that is located below the surface of said property at the sole cost and expense of the Agency. Therefore, on July 21, 2008, the Agency released a Request for Proposal ("RFP") for engineering and construction management services for the relocation of the sewer line located on said property. On November 6, 2008, the Redevelopment Committee recommended to the Commission approval of a professional services agreement with Willdan Engineering for Phase-I of a two (2) Phase scope of work and on November 17, 2008, the Commission approved the agreement by and between the Agency and Willdan Engineering. Phase-I consisted of field engineering/surveying and a feasibility study of possible relocation sites for the sanitary sewer line. Phase-I was completed and on September 15, 2009, the Relocation Study ("Study") was approved and finalized by the AOC. On April 23, 2009, the Agency entered into Amendment No. 1 to the professional services agreement with Willdan Engineering for the design and construction management phase (Phase-II) for the relocation of the sanitary sewer. With the Study finalized, the AOC, in January 2010, gave Willdan Engineering the necessary site plan information to commence the design of the sanitary sewer and prepare the bid documents. CURRENT ISSUE: On April 28, 2010, the Agency advertised for bids in accordance with State Public Contract Code Sections 10140-10141. On May 10, 2010, the sanitary sewer plans were approved by Development Services. -- ----- - -------------------------------------------------------------------------------------------------- ------- P1Agen"aICOmmDeCommi,von\CMIOIW ',IOW"In c.-PoblicWohs Con9m0wnCon1.1R1oc COMMISSION MEETING AGENDA Meeting Date: 06/07/2010 Agenda Item Number: — 7- Economic Development Agency Staff Report Weka, Inc.-Public Works Construction Contract Page 2 The Bid opening was held on May 25, 2010.

ADDENDUM NO. 1 CONSTRUCTION OF SANITARY SEWER IMPROVEMENTS AT 247 W 3'D ST., SAN BERNARDINO, CA 5. Add Appendix G —Sewer Flow Study APPENDIX G Sewer Flow Study F Executive Summary Three alternatives were evaluated for relocating the existing 18-inch sanitary sewer that currently traverses the property at 247 West 3rd Street (Property), which is being sold to the State Administrative Office of the Courts. Alternative No. 1 in which a new sewer would be routed westerly in West 3rd Street from North Mountain View Avenue to North Arrowhead Avenue and then southerly in North Arrowhead Avenue to a connection with an existing sewer north of West 2nd Street is not recommended for the following reasons: 1. At $1.90 million, it is approximately 3 times higher in estimated capital cost than both Alternative No. 2 ($614,000) and Alternative No. 3 ($668,000). 2. The sewer would be up to 25 feet deep, which would necessitate costly bore and jack construction and would result in difficult and hazardous access to the manholes for continued maintenance. 3. Construction in the street right-of-way would cause traffic disruptions in a heavily accessed area even though a large portion of the construction would be performed during off-peak periods. In both Alternative No. 2 and Alternative No. 3, the new replacement sewer would be routed on the Property southerly along the east Property line. In Alternative No. 2, the new sewer would then be routed westerly at about the midpoint of the Property, just south of the proposed building footprint and associated building ramping, to a connection with an existing sewer in North Arrowhead Avenue. In Alternative No. 3 the new sewer would continue along the east and south Property lines to a tie-in with an existing sewer in the vicinity of the North Arrowhead Avenue and West 2nd Street intersection. In both Alternative No. 2 and Alternative No. 3, the new sewer would have insufficient cover for most of the alignment. As a result, the sewer would either need to be encased in concrete and/or the existing/proposed grade would need to be raised. Raising the grade in Alternative No. 3 where the sewer alignment would parallel the southeast Property line could have an effect on the slope of Warm Creek, which also runs along the Property line. This would necessitate obtaining permits or permit waivers from a number of jurisdictional agencies, which could delay Project Construction. As Alternative No. 2 has the lowest capital cost, does not disrupt traffic in West 3rd Street and North Arrowhead Avenue, and does not have any impact on the creek, Alternative No. 2 is recommended. The estimated capital cost for Alternative No. 2 ($614,000) includes replacing an existing 30-inch sewer in North Arrowhead Avenue (approximately 240 linear feet long) because it offers insufficient pipe slope to accommodate adequate sewer hydraulics. The existing Property sewer will be removed in its entirety after the new sewer is constructed. In addition to the existing Property sewer, an existing unidentified storm drain is located on the Property. Based on the condition and characteristics of the existing site catch basins and the absence of City knowledge and/or records supporting a major area storm drain on the Property, it appears likely that this storm drain only drains the Property and is inactive or largely inactive. This will be verified during the construction phase of this project when the City Of San Bernardino Economic Development Agency WILLDAN Sanitary Sewer Relocation Study f Gtpiru Ion storm drain will be excavated. Once verified, the storm drain will be removed from the Property and the excavation will be filled and compacted with select fill up to existing grade. 1.0 Introduction The City of San Bernardino (City) Economic Development Agency (Agency) has entered into a Real Property Acquisition Agreement (RPAA) to sell the Agency-owned property at 247 West 3rd Street (APN 0135-221-22) (Property) to the State Administrative Office of the Courts (AOC). The AOC is purchasing the Property with the intention of designing and constructing court facilities and related improvements for use by the Superior Court of California, County of San Bernardino, for judicial, court, administrative, office, and related purposes. As a condition of the RPAA, the Agency is to excavate and relocate the existing 18-inch sanitary sewer traversing the Property prior to the close of escrow, which is estimated to close no sooner than July 1, 2009, with the relocation approved by the AOC. Figure No. 1, titled Alternative Alignments, shows the 18-inch Property sewer, other existing City sanitary sewers in proximity to the Property, and the three (3) proposed alternative sewer locations. This Sanitary Sewer Relocation Study (Study) has been prepared to analyze and present three (3) alternative sewer relocation alignments: Alternative 1 - Connect with the existing City sewer upstream of the Property at the intersection of North Mountain View Avenue and West 3rd Street; then construct the new sewer westerly along West 3rd Street to a point lying within the right-of-way of North Arrowhead Avenue; then southerly within said right-of-way to a connection with the existing City sewer lying within North Arrowhead. This alternative may require the replacement of a portion of the existing sewer lying within North Arrowhead Avenue to accommodate existing sewer slopes and/or increases in sewer capacities. After the new sewer is operational, the existing 18-inch Property sewer not retained to carry the proposed building flows will be removed. Alternative 2 - Connect with the existing City sewer at the northeast corner of the Property; then construct the new sewer southerly along the east Property line to approximately the midpoint of the Property; then westerly across the Property just south of the proposed building footprint and associated building ramping to a connection with the existing sewer manhole on the Property where proposed building flows will discharge. This alternative may require the replacement of a portion of the existing sewer lying within North Arrowhead Avenue to accommodate existing sewer slopes and/or increases in sewer capacities. After the new sewer is operational, the existing 18-inch Property sewer not retained to carry the proposed building flows will be removed. Alternative 3 - Connect with the existing City sewer at the northeast corner of the Property; then construct the new sewer southerly along the east Property line; then continuing along the Property line southwesterly and westerly parallel to the Property line to approximately the southwest corner of the Property; then leaving the Property to connect with the existing sewer lying in or near the intersection of North Arrowhead Avenue and West 2nd Street. This alternative may require the replacement of a portion of the existing sewer in West 2nd Street and/or North Arrowhead Avenue to accommodate existing sewer slopes and/or increases in sewer capacities. After the new sewer is operational, the existing 18-inch Property sewer not retained to carry the proposed building flows will be removed. I� Ci Of San Bernardino Economic Develo ment A enc WILLDAN Sanitary Sewer Relocation Study 2 Figure No. 1. Sanitary Sewer Relocation Alternatives City Of San Bernardino Economic Development Agency WILLDAN Sanitary Sewer Relocation Study 3 4n Arna Ian Sewer hydraulic and construction design criteria was taken from the City of San Bernardino Department of Public Works Sewer Policy & Procedures (Issued 1/5/87) (City Sewer Design Criteria). In addition to the existing Property sewer, an existing unidentified storm drain is located on the Property. This storm drain is to be removed from the Property as part of this project. If the storm drain is only a Property storm drain, i.e. the storm drain only serves the Property, the storm drain will be removed from the Property without the need to design and construct an off-site replacement storm drain first. If the storm drain is found to be connected to a larger storm drain system, i.e. flow from upstream areas drain into the storm drain, then a new replacement storm drain alignment, preferably located off of the Property, would need to be designed and constructed prior to the removal of the existing Property storm drain. 2.0 Project Mapping and Utilities Information City Geographic Information System (GIS) data for sewers, storm drains and water mains on and in the vicinity of the Property were obtained from the City. Field survey information conducted by Psomas on behalf of the AOC in August 2008 was also obtained. This survey information includes area topography and sewer locations. Additional field survey work was conducted as part of this Study to verify the accuracy of the City's GIS data, the previous survey work by Psomas, and to pick up supplementary information as required to accurately conduct this Study. One design drawing for the sewers in North Arrowhead Avenue just south of the West 2nd Street intersection to just south of the 3rd Street intersection was obtained from the City. As- built or design drawings for other connecting sewers, including the Property sewer, were not available. City personnel contacted believe these sewers to be fairly old. The survey work conducted as part of this Study verified that Psomas' survey was accurate. It also showed that the City's GIS data for sewers correlating to the one available as-built drawing was correct, but was inaccurate for some of the other connecting sewers. Psomas' survey work, the survey work conducted for this Study, and the sewer as-built drawing were used to present and evaluate existing conditions. Two existing sewer manholes that are shown on the west side of the Property per the City's GIS data were not found in the field. These manholes may or may not exist. As part of the Project Design phase, this area will be excavated as necessary to determine the existence of these manholes. If the manholes exist, are in satisfactory condition, and this portion of the sewer is to be retained to carry proposed building flows, then the manholes will need to be raised to meet proposed grade. Preliminary drawings (dated 11-21-08, prepared by Skidmore, Owings & Merrill LLP (SOM)) depicting the currently proposed building footprint and site topography for the Property were also obtained to correlate the alignments for Alternative Nos. 2 and 3 with the proposed building footprint. The locations of existing utilities in the streets surrounding the Property were obtained from the previous survey work and then verified or adjusted by contacting the utility owners and reviewing their respective utility drawings. n City Of San Bernardino Economic Development Agency WILLDAN Sanitary Sewer Relocation Study q 4�dma �ro 3.0 Project Flow Monitoring Four flow meters were installed in sewer manholes on December 4, 2008 to measure wastewater flows in the Property sewer and three other adjacent City sewers. The four meter locations are shown on Figure No. 1. The flow metering period lasted 20 days with the meters removed on December 23, 2008. Flow data for each meter site is included in the Appendix. The goal was to obtain good readings for dry-weather flow, i.e. flow not impacted by rain- induced inflow and infiltration, to design the replacement sewer in accordance with City flow depth over sewer diameter (d/D) hydraulic design criteria, which is based on peak dry- weather flow (design flow). There was no rain recorded during the first 11 days of the monitoring period (11-day dry-weather monitoring period). However, it rained 1.53 inches and 0.95 inches on December 15th and December 17th, respectively, as recorded by a National Weather Service rain gauge located at the San Bernardino County Yard. A small amount of rain was also recorded on December 22nd. Flow data recorded for all flow meters on or several days after the rain days were affected by inflow and infiltration and was not used in developing design flows in this Study. Meter Site No. 1 measured flow in the 18-inch Property sewer. The purpose was to gauge flow rates in order to size the replacement sewer and determine flow impacts for any existing tie-in sewer not currently carrying this flow. During the 11-day dry-weather monitoring period, the average flow was 127 gpm and peak flows varied from 175 gpm to 283 gpm. The high reading of 283 gpm occurred right after meter start-up and did not exceed 220 gpm after that during the first 11 days. In evaluating the data with the flow metering contractor on the project, the 283 gpm is deemed to be inaccurate (an anomaly) because the reading occurred during turbulent flow prior to the flow adjusting to the new meter. Consequently, a peak flow of 220 gpm was selected as the peak flow in the exisitng18-inch Property sewer. Meter No. 2 was installed in the manhole associated with the existing 27-inch sewer that conveys wastewater flows south on North Arrowhead Avenue. The meter was installed at this location to gauge total wastewater flow on North Arrowhead Avenue between West 3rd Street and West 2nd Street (not including the flow from the Property, which is conveyed in a parallel 30-inch sewer on North Arrowhead Avenue). The purpose was to ascertain the magnitude of flow that would be impacted if any of the alternatives required redesign of this existing sewer and/or if this flow had to be bypassed as part of an alternative. The flow was found to be fairly large with an average flow of 1,787 gpm (2.6 million gallons per day (mgd)) and an average peak flow of 2,543 gpm (3.7 mgd) over the 11-day dry-weather monitoring period. Meter No. 3 was installed in the manhole of the 15-inch sewer in North Mountain View Avenue just to the north of West 3rd Street in order to determine the flow split between this sewer and the parallel 8-inch sewer that merge downstream into the 18-inch sewer that crosses the Property. The replacement sewer would connect to both of these upstream sewers as part of Alternative No. 1. During the 11-day dry-weather monitoring period, the average flow was 56 gpm and peak flows averaged 113 gpm. Meter No. 4 was installed in the manhole of the 30-inch sewer in North Arrowhead Avenue near the intersection with West Court Street to determine the flows that would be affected City Of San Bernardino Economic Development Agency WILLDAN Sanitary Sewer Relocation Study g Sa®Nma iae should Alternative No. 1 impact this existing sewer. The flow was found to be fairly large with an average flow of 1,811 gpm (2.6 mgd) and an average peak flow of 2,777 gpm (4.0 mgd) over the 11-day dry-weather monitoring period. 4.0 Permit Requirements In Alternative No. 1, the replacement sewer would be constructed completely within street right-of-way. In Alternative Nos. 2 and 3, the replacement sewer would be constructed on both the Property and within street right-of-way. A lane closure permit must be obtained from the City Department of Development Services for construction within street right-of-way where traffic lanes must be closed to accommodate the construction. The permitee must provide a traffic control plan along with the permit application to demonstrate that traffic warning and control devices will be put in place in accordance with the latest edition of the Work Area Traffic Control Handbook as promulgated by the American Works Association. Where the sewer needs to be 15 to 25 deep in Alternative No. 1, the construction would be accomplished by boring and jacking a casing (carrier pipe) and then installing the sewer pipe in the casing (bore and jack construction). As discussed in Section 5.0, the pipe casing to be bored and jacked as part of Alternative No. 1 is estimated to be 30 inches in diameter in order to carry a 15-inch sewer pipe. Under California law, all tunnels, underground chambers and excavations, and all boring and pipe jacking projects 30 inches or greater in diameter are required to be classified by California OSHA Mining and Tunneling prior to bidding. The permit application is to be submitted for approval as soon as the soil boring logs are available. The owner/engineer must submit a tunnel classification including the owners name and address, length and diameter of casing, full size plan and profile of the tunneling location, and a geotechnical report listing any contaminated soils and/or methane gas. In Alternative No. 3, the new sewer is routed on the Property along the east property line, which is parallel to and the west of Warm Creek. As discussed in Section 8.0, based on the proposed and existing Property grades, the sewer would have a cover of approximately 3 to 4 feet where the property line runs at a 45 degree angle at the southeast corner of the Property. This cover is less than the minimum 7.5 feet of cover specified in the City's Sewer Design Criteria for a 15-inch sewer and the sewer would either need to be encased in concrete and/or the existing/proposed grade would need to be raised. Raising the grade in this area would have an effect on the creek side slope that connects with the Property line, which would potentially necessitate obtaining permits or permit waivers from the United States Army Corps of Engineers, United States Fish and Wildlife, the California Regional Water Quality Control Board, and/or California Department of Fish and Game. The need to obtain permits or permit waivers from any of these agencies would delay Project Construction. 5.0 New Development Flows The development of the new court house facilities will result in new flow inputs into the City's sewer system. SOM (the Engineer working for the AOC) has estimated a peak flow (design flow) of 621 gpm based on the new development characteristics and estimated peak court City Of San Bernardino Economic Development Agency WILLDAN Sanitary Sewer Relocation Study 6 Ga Nwv INI house population density that translates to peak wastewater generation for the Property (flow estimate received on 2-2-09). The AOC anticipates discharging all design flow from the Property into the existing westerly sewer manhole on the Property that served as Meter Site No. 1 in this Study (Property discharge manhole); then retaining that existing westerly Property sewer segment to convey Property wastewater to the existing sewer manhole in North Arrowhead Avenue if the sewer meets all City design and hydraulic criteria and is in acceptable condition. It is anticipated that the Property discharge manhole and the strategy of potentially retaining the westerly sewer segment to convey Property wastewater to the existing manhole in North Arrowhead Avenue will occur in all three alignment alternatives evaluated in this Study. When the flow meter was installed at the Property discharge manhole, (Meter Site No. 1), the upstream sewer was measured at 18 inches in diameter and the downstream sewer, which is the sewer that connects with the manhole in North Arrowhead Avenue, was measured at 20 inches in diameter. A diameter of 20 inches for vitrified clay pipe (VCP) would be unusual because VCP sewer pipe is typically manufactured in a diameter of 21 inches after a diameter of 18 inches. This pipe could be 18, 20, or 21 inches in diameter. The actual diameter can better be determined if this sewer is videotaped as part of Project Design. Two sewer manholes are shown on this westerly Property sewer segment between the Property discharge manhole and the existing sewer manhole in North Arrowhead Avenue in the City's GIS, but they were not found in the field. These manholes might exist with the covers currently buried. As part of Project Design, this area will be excavated to determine the existence of the manholes. If the manholes exist, are in satisfactory condition, and this sewer is retained, then the manholes will be raised to meet proposed grade. The sewer inverts at the Property discharge manhole and at the existing sewer manhole in North Arrowhead Avenue were surveyed by Psomas in August 2008 and then again by Willdan in November 2008. Based on the inverts by Psomas, the westerly Property sewer segment between the Property discharge manhole and the manhole in North Arrowhead Avenue has a slope of 0.0008, which is the City's minimum design slope for an 18 to 21-inch sewer per City design criteria. Based on the inverts by Willdan, the subject Property sewer has a slope of 0.0012, which is slightly above the City's minimum design slope. Psomas' and Willdan's survey information correlated very well overall, but there are small (hundredths of a foot) variations for some points throughout the surveys. At this point, neither survey is considered "more correct" than the other. However, both surveys show this sewer to have a very flat pipe slope. The possible physical and hydraulic characteristics for the westerly Property sewer segment between the Property discharge Manhole and the manhole in North Arrowhead Avenue are tabulated in Table No. 1. The characteristics are shown for both the Psomas and the Willdan surveys and for both a possible 18-inch pipe and a possible 21-inch pipe. In Alternative Nos. 1 and 3, this sewer would only carry the peak (design) flow for the Property of 621 gpm. In Alternative No. 2, the subject sewer would carry both the design flow for the Property and also the upstream design flow (220 gpm) for a total design flow of 841 gpm. �Ruile City Of San Bernardino Economic Develo ment Agency WILLDAN Sanitary Sewer Relocation Study 7 sal Table No. 1 -Characteristics of Potential Westerly Property Sewer to be Retained (Sewer between Property Discharge Manhole and North Arrowhead Avenue Manhole) It Min Pipe D.S.

A pipe friction value (N) of 0.0013 is used to evaluate sewer pipe hydraulics for VCP pipe per City Design Criteria. The minimum sewer velocity per City design standards is 2.0 feet per second (fps) at design flow. As shown in Table No. 1, the velocity in this sewer is at or less than the minimum velocity based on the sewer slope surveyed by Psomas and is only slightly above the minimum velocity based on the sewer slope surveyed by Willdan. The conclusion reached in this Study is that the hydraulic characteristics and the slope for this westerly Property sewer segment are not adequate, even where the sewer meets minimum standards, because the peak flow from the Property of 621 gpm is considered to be a worst case scenario that is not expected to occur on a regular basis, which means that the peak pipe velocity needed to clean the pipe is not expected to occur on a regular basis. If the r City Of San Bernardino Economic Development Agency WILLDAN Sanitary Sewer Relocation Study 8 tiarNeru ioe sewer is not cleaned on a regular basis by pipe flow, then there is potential for odors in the vicinity of the new courthouse. Considering that this sewer is also considered to be old, it is recommended that this westerly Property sewer segment be replaced with a new sewer designed with a smaller pipe diameter and a steeper pipe slope. 6.0 Alternative No. 1 Alternative No. 1 is shown in detail on Figure No. 2, which is a map located in the back pocket of this Study. In Alternative No. 1, a new sewer will be constructed to connect with existing 8-inch and 15-inch sewers upstream of the Property at the intersection of North Mountain View Avenue and West 3rd Street. These two sewers carry flow to the existing 18- inch sewer that crosses the Property. There is evidence that additional sewer manholes might exist below the street pavement at this intersection and the existing 15-inch sewer might actually align more to the east as shown on Figure No. 2. This area will be potholed as part of design to verify the location of the 15-inch sewer. The hydraulics of Alternative No. 1 sewers are shown in Table No. 2. As discussed in Section 3.0, a peak flow of 220 gpm was selected as the existing design (peak) flow in the existing 18-inch Property sewer. In order to meet City minimum slope and velocity requirements (2.0 fps), the new sewer is sized at 15 inches in diameter. Also, the new sewer pipe needs to be constructed of polyvinyl chloride (PVC) in order to meet the minimum velocity requirement because PVC has a smoother pipe surface than VCP pipe (pipe friction N = 0.0011 for PVC pipe and N = 0.0013 for VCP pipe per City sewer design criteria). Note that the minimum slope requirement is 0.004 for a 12-inch sewer and is 0.0008 for a 15-inch sewer. The new 15-inch sewer will be constructed by open cut (trenching) in West 3rd Street for approximately 350 linear feet (If), at which point the sewer depth will be approximately 15 feet. In the vicinity of the West 3rd Street and North Arrowhead Avenue intersection, the sewer will need to be approximately 25 feet deep. Due to the sewer depth, bore and jack construction is deemed appropriate. A receiving pit will be excavated just to the east of the West 3rd Street and North Arrowhead Avenue intersection. A 30-inch casing will be bored and jacked from a bore pit excavated in West 3rd Street, about 300 feet east of the receiving pit. The 15-inch sewer would be installed inside the 30-inch casing pipe. A second bore pit will be excavated about 300 feet south of the receiving pit in the east sidewalk area of North Arrowhead Avenue. A 30-inch casing will be bored and jacked from this bore pit to the receiving pit to carry the 15-inch sewer. The new 15-inch sewer will then be trenched to an existing sewer manhole about 30 feet away in North Arrowhead Avenue (manhole labeled M6 on Figure No. 2). This is the same manhole that the existing 18-inch to 21-inch Property sewer connects with. Note that there is no upstream flow coming into this manhole as the 24-inch sewer connecting from the north is abandoned. In order to meet the minimum velocity requirement of 2.0 fps for the entire upstream alignment, the new sewer needs to be about 5 inches lower than the existing manhole invert elevation, and as a result, this manhole and the existing downstream-connecting 30-inch sewer will need to be replaced (about 240 If). The design flow from the new courthouse (621 gpm) will also be conveyed from the Property to this new manhole. The resultant combined 2 City Of San Bernardino Economic Development Agency WILLDAN Sanitary Sewer Relocation Study g SiA V IIIA design flow in the downstream sewer is 841 gpm. The new sewer to replace the existing 30- inch sewer in North Arrowhead Avenue (sewer labeled S6 in Table No. 2 and in Figure No. 2) is sized at 15 inches in diameter in order to attain appropriate scouring velocities. Note that the existing 30-inch sewer was originally designed to carry much larger sewer flows in North Arrowhead Avenue and is too large to carry just the 841 gpm from the Property. The new 15-inch replacement sewer will connect with the existing sewer manhole just to the north of the West 2nd Street and North Arrowhead Avenue intersection (M7 on Figure No. 2).

The new sewer to replace the westerly Property sewer segment is labeled S7 in Table No. 2 and in Figure No. 2. The costs associated with the Alternative No. 1 are shown in Table No. 3. Construction cost includes 7% for project mobilization and a 20% construction contingency. Capital cost includes project technical, legal, and administrative costs and are estimated at 15% of construction cost. Note that some of the project engineering and construction management costs have already been accounted for. As shown in Table No. 3, a capital cost of $1.90 million is estimated for Alternative No. 1. 7.0 Alternative No. 2 Alternative No. 2 is shown in detail on Figure No. 3, which is a map located in the back pocket of this Study. In Alternative No. 2, a new 15-inch sewer would be constructed to connect with the existing 18-inch City sewer at the northeast corner of the Property (manhole labeled M1 on Figure No. 3). The hydraulics of Alternative No. 2 sewer pipes are shown in Table No. 4. In order to meet City minimum slope and velocity requirements of 2.0 fps at a design flow of 220 gpm, the new sewer is sized at 15 inches in diameter and should be constructed of PVC. The new 15-inch sewer will be routed south just inside the east Property line to approximately the midpoint of the east Property line to manhole M2. Based on the existing and proposed grades of the Property, the sewer will have 2.5 to 3.8 feet of cover to manhole M2. This is less than the 7.5 feet minimum cover specified in the City Sewer Design Criteria for a 15-inch sewer. Therefore the sewer will need to be encased in concrete or the existing/proposed grade will need to be raised. Then, from the approximate mid-point of the east Property line, the new 15-inch sewer will be routed west across the Property to the Property discharge manhole (manhole M3 in Figure No. 3). Based on the existing and proposed grades of the Property, the sewer will have about 2.5 to 9.0 feet of cover to manhole M3. The sewer may need to be encased in concrete and/or the existing/proposed grade may need to be raised for some or all of this sewer segment alignment. As discussed in Section 5.0, it is recommended that the westerly Property sewer that runs from the Property discharge manhole to the North Arrowhead Avenue manhole be replaced due to poor hydraulic characteristics that could cause odor problems in the vicinity of the new courthouse. The new sewer to replace the westerly Property sewer segment is labeled S3 in Table No. 4 and in Figure No. 3. New manhole M3 cannot be raised above its existing invert elevation or else a minimum velocity of 2.0 fps cannot be obtained in the new upstream Property sewer segments at design Flow. Consequently, the only way to obtain a steeper pipe slope for the westerly Property sewer segment is to lower the manhole in North Arrowhead Avenue, which means the downstream —connecting 30 inch sewer will also need to be replaced. The new sewer to replace the westerly Property sewer segment is labeled S4 in Table No. 4 and in Figure No. 3. ;OOP"O Cit Of San Bernardino Economic Develo ment A enc WILLDAN Sanitary Sewer Relocation Study 11 Table No. 3- Estimated Cost of Alternative No. 1 Sewer Sewer or Unit MH Sewer MH Cost Unit Construct Capital or Construction Depth r . 2(b) Cost Cost(O COSt(d) MH Method (ft) M1 Excavate 8 - $ 6,000 $ 7,700 $ 8,900 S1 Trench 8 12 15 $ 200 $ 35 $ 4,500 $ 5,200 M2 Excavate 8 $ 6,000 $ 7,700 $ 8,900 S2 Trench 8-15 15 347 $ 325 $ 35 $ 160,400 $ 184,500 M3 Excavate 15 - $ 8,500 $ 10,900 $ 12,500 S3 Bore&Jack 15-25 15 300 $1,500 1 $ - - $ 577,800 $ 664,500 M4 Excavate 25 $12,000 $ 15,400 $ 17,700 S4 Bore&Jack 16-25 15 303 $1,500 $ - $ 583,600 $ 671,100 M5 Excavate 16 - $ 8,500 $ 10,900 $ 12,500 S5 Trench 16 15 30 $ 350 $ 35 $ 14,800 1 $ 17,000 M6 Excavate 16 $ 8,500 $ 10 900 $ 12 500 S6 Trench 9-16 15 239 $ 325 $ 35 j 110,500 $ 127,100 M8 Excavate 10 - $ 6,000 $ 7,700 $ 8,900 S7 Trench 10-16 15 232 $ 300 $ $ 89,400 $ 102.800 Subtotal 1,466 $1,612,000 $1,854,000 Remove Property Sewedr 6-16 18-21 670 $ 50 $ $ 43,000 $ 49,000 Total 2,136 $1,655,000 $1,903,000 a) Unit cost to construct sewer b) Unit cost for traffic control and/or pavement replacement associated with sewer construction c) Includes 7%for project mobilization and a 20%construction contingency d) Includes technical, legal, and administrative costs estimated to be 15%of construction cost e) Includes cost to remove existing 30"sewer f) Unit cost for bore & jack includes costs for excavation, traffic control, and pavement replacement associated with bore and receiving pits.

This will necessitate obtaining permits or permit waivers from the United States Army Corps of Engineers, United States Fish and Wildlife, the California Regional Water Quality Control Board, and/or California Department of Fish and Game. The need to obtain permits or permit waivers from any of these agencies will delay Project Construction. From manhole M4, the new sewer will connect with the existing sewer manhole located in North Arrowhead Avenue, manhole M5. Based on the existing grade, the sewer will have about 5.1 to 5.4 feet of cover between manholes M4 and M5, and as a result, the sewer will need to be encased in concrete. As discussed in Section 5.0, it is recommended that the existing westerly Property sewer segment from the Property discharge manhole (M6 on Figure No.4) to the existing manhole in North Arrowhead Avenue be replaced. A steeper pipe slope for the westerly Property sewer segment can be obtained by raising manhole M6, which means the manhole in North Arrowhead Avenue does not need to be lowered. Consequently, the downstream-connecting 30-inch sewer can be retained.

Capital cost includes project technical, legal, and administrative costs and are estimated at 15% of construction cost. Note that some of the project engineering and construction management costs have already been accounted for. As shown in Table No. 7, a capital cost of $668,000 is estimated for Alternative No. 3 including the cost for replacing the r, City Of San Bernardino Economic Dew10 ment Agency WILLDAN Sanitary Sewer Relocation Study 16 $aAllnla Iaa westerly Property sewer segment. The additional capital cost to replace the westerly Property sewer segment is estimated at $112,000. 9.0 Property Storm Drain There are three catch basin inlets on the Property that are evidence of a storm drain that drains the Property and/or is part of a larger area storm drain system. Two of the inlets are buried with dirt up to the grate and are inactive. The top of the third catch basin is elevated more than a foot above the existing ground. This catch basin appears to be old and may have been constructed to accommodate previous property characteristics. Water has been observed in this catch basin, but it most likely is water percolating from the site sprinkler system. The City has jurisdiction over all local drainage facilities including the Warm Creek drainage system, which drains areas north and northeast of the Property, as well as the Property itself. City personnel contacted do not believe that a significant storm drainage system is located on the Property and no record drawings could be found to support the existence of one. Local drainage patterns do not support the existence of a second major drainage system cutting across the Property and/or connecting with the Warm Creek system. Based on the condition and characteristics of the existing site catch basins and the absence of City knowledge and/or records supporting a major area storm drain on the Property, it appears that the storm drain on the Property only drains the Property and is inactive or largely inactive. This will be verified during the construction phase of this project when the storm drain will be excavated. Once verified, the storm drain will be removed from the Property and the excavation will be filled and compacted with select fill up to existing grade. 10.0 Conclusions and Recommendations 10.1 Recommended Sewer Alignment Of the three sewer alignment alternatives evaluated, Alternative No. 1 is by far the most expensive. At $1.90 million, it is approximately 3 times higher in estimated capital cost than both Alternative No. 2 ($614,000) and Alternative No. 3 ($668,000). Although Alternative No. 1 is entirely within the street right-of-way, the sewer would be up to 25 feet deep, which would necessitate costly bore and jack construction and would result in difficult and hazardous access to the manholes. Construction in the street right-of-way would cause traffic disruptions in a heavily accessed area even though a large portion of the construction would be performed during off-peak periods. Alternative No. 1 is not recommended. Alternative Nos. 2 and 3 would be on the Property except where they tie into existing sewer manholes on North Arrowhead Avenue. Construction of these alternatives would be less costly, less complex, and would be less disruptive than in Alternative No. 1. However, insufficient sewer cover is a problem associated with both Alternative Nos. 2 and 3. The sewers would have between 2.5 and 5 feet of cover for the most part. This cover is less than the minimum 7.5 feet specified in City Sewer Design Criteria for a 15-inch sewer. As a result, where the cover is less than the minimum, the sewers will either need to be encased in concrete and/or the existing/proposed grade will need to be raised. City Of San Bernardino Economic Development Agency WILLDAN Sanitary Sewer Relocation Study 17 Saa6ena loo Raising the grade in Alternative No. 3 where the sewer alignment would parallel the southeast Property line will have an effect on the creek slope that runs along the Property line. This will necessitate obtaining permits or permit waivers from the United States Army Corps of Engineers, United States Fish and Wildlife, the California Regional Water Quality Control Board, and/or California Department of Fish and Game. The need to obtain permits or permit waivers from any of these agencies will delay Project Construction. Raising the grade in Alternative No. 2 is not expected to have any impact on the adjacent creek as the alignment is sufficiently removed from the creek area of influence. As Alternative No. 2 has the lowest capital cost, does not disrupt traffic in West 3rd Street and North Arrowhead Avenue, and does not have any impact on the creek, Alternative No. 2 is recommended. 10.2 Continued Use of a Portion of the Property Sewer The AOC anticipates discharging all design Flow from the Property into the existing westerly sewer manhole on the Property that served as Meter Site No. 1 in this Study (Property discharge manhole); then retaining that existing westerly Property sewer segment to convey Property wastewater to the existing sewer manhole in North Arrowhead Avenue if the sewer meets all City design and hydraulic criteria and is in acceptable condition. The conclusion of this Study is that the hydraulic characteristics and the slope of the westerly Property sewer segment are not adequate, especially considering that the peak flow from the Property of 621 gpm is a worst case scenario that is not expected to occur on a regular basis, which means that the peak pipe velocity needed to clean the pipe is not expected to occur on a regular basis. If the sewer is not cleaned on a regular basis by pipe flow, then there is potential for odors in the vicinity of the new courthouse. Considering that this sewer is also considered to be old, it is recommended that this westerly Property sewer segment be replaced with a new sewer designed with a smaller pipe diameter and a steeper pipe slope. In Alternative No. 2, the only way to obtain a steeper pipe slope for the westerly Property sewer segment is to lower the manhole in North Arrowhead Avenue, which means the downstream —connecting 30 inch sewer will also need to be replaced. It is recommended in this Study that both the westerly Property sewer segment and the 30- inch sewer in North Arrowhead be replaced as part of Alternative No. 2. 10.3 Property Storm Drain Based on the condition and characteristics of the existing site catch basins and the absence of City knowledge and/or records supporting a major area storm drain on the Property, it appears likely that the storm drain on the Property only drains the Property and is inactive or largely inactive. This will be verified during the construction phase of this project when the storm drain will be excavated. Once verified, the storm drain will be removed from the Property and the excavation will be filled and compacted with select fill up to existing grade.

The location of the project site is shown on Figure 1, Site Location Map. The approximate locations of the soil borings advanced for this investigation are shown on Figure 2, Boring Location Map, along with the locations of borings advanced by others during previous investigations at the site. This report includes geotechnical conclusions and recommendations with respect to site preparation and earthwork procedures including utility trench backfill. ' A boring log key and the boring logs are presented in Appendix A.The logs of borings drilled by others as part of earlier studies are included as Appendices B and C. The geotechnical laboratory test results are in Appendix D, and the results of a Seismic Hazard Analysis are presented in Appendix E. 1.1 PURPOSE AND SCOPE OF SERVICES This investigation was conducted to explore and evaluate the site soil and groundwater conditions to depths that will significantly be influenced by the proposed construction.Our scope ' of services included the following: • A site reconnaissance by a member of our engineering staff to evaluate the surface ' conditions at the project site. • Review of selected published geologic maps, reports and literature pertinent to the site and surrounding area. ' • A field investigation consisting of drilling four (4) borings to evaluate subsurface conditions at the site.The borings ranged in depth from approximately 21%2 to 36-%2 feet below existing ground surface(bgs). • Performance of laboratory tests on representative soil samples obtained from the borings to evaluate the physical properties of the subsurface soils. • Performance of laboratory tests on one (1)composite sample of soils collected within the proposed pipe zone to assess corrosivity of the soil as it pertains to soil/cement reactivity and buried metals. • Engineering evaluation of the data obtained from the field investigation and laboratory testing program and development of geotechnical recommendations for earthwork and pavement sections. 1 Proposed Sanitary Sewer Line Relocation City of San Bernardino, California Willdan Project No. 17349-4004 • Preparation of this report summarizing our investigation and findings, results of geotechnical laboratory testing, and our conclusions and recommendations for the ' geotechnical aspects of project design and construction. Environmental assessment services, such as chemical analysis of soil and groundwater for hazardous substances, were not included in our scope of services. Geotechnical services related to soil corrosivity have been limited to screening of one(1)composite soil sample collected from within the proposed pipe zone. Thorough corrosivity evaluation with respect to the potential for ' on-site soils to affect cement (concrete) or buried metal pipe was not included in our scope of services for this project. 1.2 SITE DESCRIPTION AND PROPOSED DEVELOPMENT The project lies within the City of San Bernardino ("City"), the county seat of San Bernardino ' County, California. The city lies in the San Bernardino foothills and the eastern portion of the San Bernardino Valley, roughly 65 miles(105 km)east of Los Angeles. The subject property comprises approximately 10 acres and is located southeast of the intersection of Third Street and Arrowhead Avenue. The site is bounded by Third Street to the north, Arrowhead Avenue to the west, Second Street to the south,and Meadowbrook Park to the east. The immediate area of the project site is almost flat. Warm Creek Channel runs through the southeastern quarter of the site. At the time of our field study, a parking lot paved with asphalt concrete was present in the northern third of the site.The remainder of the site was unpaved. ' The proposed improvements comprise replacement of approximately 860 feet of 18-inch- diameter sanitary sewer lines with 981 feet of 15-inch-diameter PVC sewer lines. The alignments of the existing sanitary sewer line and the proposed replacement line are provided in Figure 2, Boring Location Map. 2.0 GEOLOGY 2.1 GEOLOGICAL SETTING San Bernardino and its namesake valley lie near the northern margin of the Peninsular Ranges geomorphic province, one of the 11 provinces recognized in California. The peninsular Ranges encompass southwestern Caledonia, west of the Imperial-Coachella Valley trough and south of the elevated terraces of the San Gabriel, San Bernardino, and Santa Monica Mountains. The province is characterized by youthful, steeply sloped, northwest-trending, elongated ranges and ' intervening valleys. In gross aspect, average elevations across the province rise slowly to the 2 Proposed Sanitary Sewer Line Relocation City of San Bernardino, California Willdan Project No. 17349-4004 teast, usually culminating in abrupt escarpments near the eastern margin. Several anomalously flat and low basins stretch from the San Bernardino region to western Los Angeles. The Basins result from the geometry of the fault junctures and tectonic interaction with the adjunct Transverse Ranges. Structurally, the Bulk of the Peninsular Ranges province is composed of a number of relatively stable crustal blocks bounded by active strike-slip faults of the San Andreas transform system. Although some folding and minor faulting has occurred within the blocks, intense structural deformation and earthquake activity are mostly limited to block margins. The San Bernardino Valley is not an erosional feature; it is a deep structural basin that is believed to be slowly subsiding in response to the transference of slip from the San Jacinto fault to the San Andreas Fault(Hilltop Geotechnical, Inc,2007). The Peninsular Ranges province contains a diverse array of metamorphic, sedimentary and igneous rocks. Inland, the province is dominated by crystalline basement rocks. In general, the metamorphic rocks represent highly-altered host rocks formed during emplacement of very large, plutonic masses of varying granitic rock composition. Closer to the coastline, younger rocks include thick sequences of marine and non-marine, clastic, sedimentary rocks ranging from claystones to conglomerate. These sedimentary formations generally are of late-Mesozoic and Tertiary age. Quaternary alluvium forms several massive fans extending from the mouths of Lytle Creek, Cajon Creek, and Santa Ana Canyons. Smaller alluvial fans extend from smaller canyons to the north and northeast of the subject site. The predominant source of sedimentary material for the subject site likely is the Santa Ana Canyon, but material from several sources appears to be present. The inferred depth of Quaternary alluvium at the subject site is several hundred feet, based on the water well record in the area(Hilltop Geotechnical, Inc, 2007) 2.2 REGIONALAND LOCAL FAULTS Seven major faults are located within 20 kms of tfie boundaries of the project area — the San Jacinto Fault Zone (Rialto Colton Fault, and Lytle Creek Fault), the San Andreas Fault Zone (San Bernardino Mountain), the Waterman Canyon Fault, the Crafton Hills Fault zone, the Cleghorn Fault Zone and the Cucamonga Fault. Fault locations are taken from the online database maintained by USGS (USGS, 2009). ' The Rialto Colton Fault(San Jacinto Fault zone) lies approximately 5.3 kms south-southwest of the project site and is capable of producing an earthquake of magnitude 6.75. The San Andreas Fault Zone (San Bernardino Mountain), located approximately 8 kms to the north-northeast, is I considered capable of producing an earthquake of magnitude 7.4. The Crafton Hills Fault Zone is located approximately 8.5 kms to the southeast, and is considered capable of an earthquake of magnitude 6.5. The Lytle Creek Fault (San Jacinto Fault Zone) is located approximately 10 kms ' to the north and is considered capable of producing an earthquake of magnitude 6.75. The Waterman Canyon Fault, located approximately 12 kms to the north-northeast, is considered 3 Proposed Sanitary Sewer Line Relocation City of San Bernardino, California Wiltdan Project No. 17349-4004 capable of producing an earthquake of magnitude 7.3. The Cucamonga Fault is located approximately 16 kms to the northwest and is considered capable of producing an earthquake of magnitude 6.9. And the Cleghorn Fault, located approximately 19 kms to the north-northeast, is considered capable of producing an earthquake of magnitude 7.75. 3.0 FIELD AND LABORATORY INVESTIGATIONS Field exploration for this investigation consisted of drilling and sampling four(4) soil borings on January 12, 2010. Borings were advanced to depths between 21!/z and 36-%: feet bgs. Approximate locations of the borings are shown on Figure 2, Boring Location Map. These locations were estimated by our personnel in the field using a measuring wheel and measuring from the limits of existing site features. Prior to field exploration, a site visit was performed to mark the boring locations and evaluate access conditions for drilling equipment. Underground Service Alert of Southern California was then notified for clearance of underground utilities in the vicinity of the borings (Ticket Number A60772) Soil borings for the current investigations were advanced using a truck-mounted B-61 rig equipped with 8-inch diameter hollow-stem augers. Relatively undisturbed, disturbed, and bulk soil samples were collected from each soil boring during drilling. Bulk samples were collected from auger cuttings obtained from within the near-surface soils. At select intervals throughout the boring depths, relatively undisturbed soil samples were collected by driving a three-inch outside diameter Modified California Sampler lined with brass rings,and disturbed samples were collected by driving a 1%-inch inside diameter Standard Penetration split-spoon sampler. The samplers were driven into the underlying soil to a depth of 18 inches,or the interval noted on the boring logs,with a 140-pound hammer falling 30 inches.The number of blows required to drive the sampler was recorded for each 6-inch penetration interval and is shown on the boring logs. ' Soil samples were retained from possible laboratory testing. The number of blows required to drive the sampler the last 12 inches was used to estimate the in-situ relative density of granular soils and to a lesser degree of accuracy,the consistency of cohesive soils. Visual classification of the soils encountered in our exploratory borings was made in general accordance with the Unified Soil Classification System (ASTM D2487). A key for the classification of the soils(USCS classifications)along with the logs of our borings is included as Appendix A. Logs of borings conducted b y others during previous investigations at the site are included herein as Appendices B&C. Upon completion of drilling, the borings were backfilled with soil cuttings and tamped. Soil samples collected from the field were delivered to Willdan's laboratory for testing. 4 Proposed Sanitary Sewer Line Relocation City of San Bernardino, California Willdan Project No. 17349-4004 Laboratory tests were performed on selected soil samples to evaluate their physical characteristics and engineering properties. Laboratory testing included determination of in-situ 1 moisture and density, gradation, percent passing # 200, modified proctor compaction and shear strength characteristics for soil samples collected from various depths, and corrosion potential of soils collected from within the proposed pipe depths. Laboratory tests were conducted in general accordance with American Society for Testing of Materials Standards (ASTM 2009) or California Test Methods. The in-situ dry density and moisture content test results are shown on the boring logs. The remaining laboratory test results are presented in Appendix D, Laboratory ' Test Results. 3.1 SOIL.PROFILE AND SUBSURFACE CONDMONS The following subsurface descriptions are based on data obtained from the field observations of soil type,and laboratory testing for the current investigation, and from the information available from two previous investigations done at the site,one by Environmental Resources Management in 2008 and one by Hilltop Geotechnical, Inc in 2007. The available geotechnical information indicates that fine to medium-grained silty sands are present as a fill material in approximately the upper two feet of the proposed sewer alignment. Below the fill material, interbedded layers of fine silty sands and sandy silts predominate in the upper 15 to 20 feet of the subsurface.These sandy/silty materials are generally in a medium dense/stiff to dense/stiff state. Below depths of approximately 20 feet bgs, coarser grained materials such as sand and gravel were encountered to a depth of 36-1/2 feet bgs — the final depths of our borings. The dry density of the existing surficial fill and the native soils within the pipe zone is approximately 100 t 4 pounds per cubic foot(pco.The moisture content of this material ranges between 4 and 18 percent. Based on our findings, the subsurface conditions encountered appear typical of those found in the geologic region of the site. The above is a general description of soil conditions-encountered at the site in the borings drilled for this investigation. For a more detailed description of the soil conditions encountered, please refer to the boring logs in Appendix A. �j 3.2 GROUNDWATER The borings conducted for the current investigation were monitored for visible signs of free groundwater during and immediately after completion of the borehole/sounding.No groundwater was seen in any of the four (4) borings advanced during the current investigation. No 1 groundwater was encountered down to the maximum depth of exploration of 50 feet in seven of the eight (7 of 8) relevant borings drilled during previous investigations (see Figure 2, Boring Location Map). Groundwater was encountered in boring BB-3, drilled on August 8, 2007, at a depth of approximately 45 feet bgs. 5 r ' l Proposed Sanitary Sewer Line Relocation City of San Bernardino, California Willdan Project No. 1 734 9-4004 Although no groundwater was seen within the pipe zone, the project site is near downtown San Bernardino,an area that has recorded historically high groundwater levels. Issues of groundwater infiltration into building basements have been recorded within one-quarter mile of the subject site. During the late 1880s, a marsh was mapped within a city block or two to the north of the project area (CDMQ 1976). While the marsh was not shown on the project site, presence of a marsh nearby indicates a high probability of shallow groundwater in the project vicinity. Additionally, a review of available groundwater contour maps indicates that the historically highest groundwater in the general area of the project site is approximately 10 feet bgs (Hilltop Geotechnical, 2007). Depth to groundwater can be expected to fluctuate both seasonally and from year to year. Fluctuations in the groundwater level may occur due to variations in precipitation, flow in nearby creeks, irrigation practices at the site and in the surrounding areas, climatic conditions, pumping from wells, and possibly as the result of other factors that were not evident at the time of our investigation. 4.0 SEISMIC DESIGN CONSIDERATIONS 4.1 SITE CHARACTERIZATION—SITE CLASS The subsurface soil profile at the site can be classified from a seismic standpoint based on the conditions encountered in our exploratory borings, and anticipated within the upper 100 feet of the site based on geologic mapping, as being a relatively stiff soil with undrained shear strength of at least 1,000 pounds per square foot(psf)and SPT N values of 15 to 50 blows per foot. Based on the soils encountered within the upper 50 feet of the subject site and with consideration of the r geologic units mapped in the area, it is our opinion that the site soil profile corresponds to Site Class D as per Table 1613A.5.2 of the California Building Code(CBC,2007). 4.2 GROUND SHAKING Although ground rupture is not considered to be a major concern at the subject site, the site will likely be subject to moderate to severe seismic shaking during its lifetime. Some degree of infrastructural damage due to stronger seismic shaking should be expected at the site, but the risk can be reduced through adherence to seismic design codes. Using the seismic hazard assessment program developed by the United States Geologic Survey (USGS, 2005), the design ground motion, taken as two-thirds of the MCE ground motion, is calculated as 0.42g. Results of the probabilistic seismic hazard deaggregation analysis are presented in Appendix E, Site Seismic Analysis. r 6 it Proposed Sanitary Sewer Line Relocation City of San Bernardino, California Willdan Project No. 17349-4004 4.3 SOIL LIQUEFACTION Soil liquefaction is a state of temporary soil particle suspension caused by loss of strength due to an increase in pore pressures because of the cyclic stress induced by earthquakes. Liquefaction normally occurs in saturated granular soils, such as sands, in which the strength is purely frictional. Soils most susceptible to liquefaction are saturated, loose, uniformly graded, fine- grained sand deposits. However, liquefaction has occurred in soils other than clean sands. Silty sands and sandy silts have also been reported to be susceptible to liquefaction or partial liquefaction. The occurrence of liquefaction is generally limited to soils located within about 50 feet of the ground surface. Primary factors affecting the potential for a soil to undergo liquefaction include: 1) Depth to groundwater; 2) Soil type; 3) Relative density of the soil and initial confining(overburden)pressure; 4) Intensity and duration of ground shaking. Potential problems associated with soil liquefaction include ground surface settlement, loss of foundation bearing support strength, and lateral spreading. Ground surface settlement due to densification of the liquefied soils can be approximated using procedures developed by Tokimatsu and Seed (1987) and Ishihara and Yoshimine (1992). While confinement of saturated sand layers is required for liquefaction to occur, a phenomenon referred to as sand boils is the primary cause for catastrophic failure of building foundations. Sand boils occur when the sudden compression of groundwater in a layer of saturated, clean, loose sand builds up sufficient pressure to rupture up through the upper soil mantle to the ground surface. When this occurs, displacement of the liquefied sand results in the sudden loss of support of structures supported by shallow foundations. The project site has not been mapped as being within a zone susceptible to liquefaction as designated by the State of California. Additionally, data available from the previous investigations at the project site, as well as the data obtained from the present geotechnical investigation conducted along the proposed new sanitary sewer alignment indicate that the sandy and silty materials in the pipe zone are not likely to undergo liquefaction. Nonetheless, because historic data indicate the potential for the groundwater to rise to within the pipe zone, site- specific liquefaction potential was analyzed. Our analysis indicates that the sandy materials present in the pipe zone, the upper 5 to 16 feet of the subsurface, are highly unlikely to undergo liquefaction even if the water table rises to within 10 feet of the existing ground surface. 7 Proposed Sanitary Seiver Line Relocation City of San Bernardino,California WiBdan Project No. 17349-4004 4.4 SEISMICALLY INDUCED SETTLEMENT OF UNSATURATED SANDS In addition to the settlement of sand deposits that undergo liquefaction, strong seismic shaking can also cause settlement or compaction of sands above the groundwater as well. Seismic- induced settlement of sands above the groundwater can potentially result in settlement of the ground surface. Under the design seismic scenario for the project site,the estimated settlement of the medium dense sandy materials encountered in the pipe zone is estimated to be less than one one-half inch(Y2-inch)everywhere along the proposed pipeline alignment. 4.5 LATERAL SPREADING Lateral spreading happens when surficial soil moves in a direction parallel to the ground surface due to liquefaction of underlying subsurface soils layers. Lateral spreading usually occurs where the ground surface has a slope less than 6 percent and may result in damage to structures or other improvements due to differential lateral movements (Naeim, 1989). Lateral spreading is not likely to occur at the project site during seismic events. 4.6 GROUND LURCHING Ground lurching is movement of the ground surface during seismic event, resulting in cracks and ridges developing perpendicular to the slope face. Areas underlain by thick alluvium with loose granular soils or clay soils with high moisture are susceptible to ground lurching. Ground lurching often causes damage to lightly loaded structures such as pavements, walkways, pipelines, and other near-surface improvements located within the failure zone. The shallow subsurface within the pipe zone consists predominately of medium dense granular materials and stiff fine-grained materials. As such, the pipe zone is not susceptible to ground lurching during the design earthquake event. Nonetheless, we recommend that the planned new sewer lines and other underground utilities in areas where excavation reveals loose materials in the pipe zone be designed and constructed with flexible joints to minimize the potential for pipe rupture due to �! ground lurching during a seismic event. 4.7 SEISMIC PARAMETERS—2007 CALIFORNIA BUILDING CODE The site class per Table 1613.5.2, of the 2007 California Building Code (2007 CBC) is based upon the site soil conditions. It is our opinion that Site Class D is most consistent with the subject site soil conditions. For design of structures based on the seismic provisions of the 2007 CBC, we recommend the parameters in the following Table 1: 8 Proposed Sanitmy.Seuvr Line Relocation City of San Bernordino, California Willdon Proiect No. 77349-4004 TABLE 1.

Presented below are recommendations for pipeline installation, and other geotechnical aspect of the project for incorporating in the project plan and specifications. 5.1 SITE GRADING The anticipated site grading activities will consist of site preparation, excavation and removal, subgrade preparation, backfilling, and other earthwork activities described in the following paragraphs. All site grading activities should be performed in accordance with the local grading codes and the latest edition of the Standard Specifications for Public Works Construction (Greenbook, 2009), where applicable. The more stringent requirements between the two should prevail. 5.2 UTILITY TRENCH BEDDING AND BACKFILL iBedding materials consisting of sand, gravel, or crushed aggregate should be used to backfill around utility pipes to approximately 1 foot above the top of a pipe. Onsite soils which have a Sand Equivalent (SE) of 30 or greater can also be used as bedding. Prior to placing the pipes. the pipe trench subgrade should be observed by a representative of the project geotechnical 9 or I Proposed Sanitary Sewer Line Relocation City of San Bernardino,California Willdan Project No. 17349-4004 engineer. If the exposed subgrade is loose or unstable, the unsuitable subgrade soil must be excavated and replaced with bedding material. Bedding must be placed uniformly on each side of the pipe and mechanically compacted. Flooding or jetting to densify the bedding materials may be used, provided no clayey materials are included in the backfill.The fill should be placed in loose lifts not to exceed 8 inches, moisture-conditioned to 2 to 4 percent above optimum, and mechanically compacted to at least 90 percent relative compaction in accordance with ASTM D1557. Thinner lifts may be necessary to achieve the recommended level of compaction of the backfill due to equipment limitations. Trenches in pavement areas should be capped with at least 12 inches of compacted, on-site soil similar to that of the adjoining subgrade. The upper 12 inches of trench backfill in areas to be paved should be compacted to at least 95 percent relative compaction. Special care should be taken in the control of utility trench backfilling in the pavement areas. Poor compaction may cause excessive settlement resulting in damage to the pavement structural section. Where trenches exceed ten feet in depth from the ground surface,the percent relative compaction of cohesive soils may need to be increased to reduce the potential for trench backfill settlement. Should these conditions exist, compaction requirements should be reviewed by the Geotechnical Engineer as a part of the plan review process. 53 BULKING AND SHRINKAGE The change in volume of excavated materials upon replacement and recompaction as fill varies according to soil type, density, and location. This volume change is represented as a percentage increase (bulking) or decrease (shrinkage) in volume of fill after removal and recompaction. Based on our laboratory testing data, we estimate the near-surface onsite soil will have average compaction shrinkage on the order of 10 percent. This estimate does not factor in removal of oversize material or debris, if any. 5.4 LATERAL RESISTANCE For design, resistance to lateral loads from thrust blocks or other appurtenant structures will be provided by the passive earth pressure. An allowable passive earth pressure of 350 psf per foot of depth is recommended. The maximum passive resistance should not exceed 2,500 psf. The allowable passive pressure may be doubled for isolated thrust blocks. 5.5 SOIL CORROSIVITY AND SULFATE ATTACK POTENTIAL rExcessive sulfate or chloride in either the soil or native water may result in an adverse reaction between the cement in concrete and the soil. Concrete mix design criteria for concrete structures in contact with soils containing sulfate or chloride are addressed in the California Building Code. r Soils can also react with buried metals resulting in corrosion. 10 It Proposed Sonitaty Seger Line Relocation City ofsan Bernardino, California Willdan Project No. 1"49-4004 A composite sample of the onsite soils was tested for soluble sulfate and chloride content, and for determination of pH and resistivity.Test results indicate a pH value of 7.6, resistivity of about 1,400 ohm-cm, and sulfate and chloride concentrations of 140 and 686 ppm, respectively. Although both soluble sulfates and soluble chlorides were detected, these concentrations are considered insufficient to damage reinforced concrete and no special precautions, such as I specific cement type, water-cement ratio or compressive strength, are required in design of the concrete mix to be used for concrete in contact with soils at the project site. The laboratory measured pH and resistivity indicate that some zones of the proposed sewer line alignment may be mildly corrosive to buried ferrous metals. We recommend a minimum pipe thickness of 16 gage for buried metal pipes for protection against perforation over a 50 year life. The amount of soluble sulfate indicates a negligibly corrosive environment for reinforced concrete. Based on the measured chloride concentration, we recommend a minimum concrete cover of 2-%z inches over reinforcement for reinforced concrete embedded within the near-surface soils. 5.6 REVIEW OF CONSTRUCTION PLANS Recommendations contained in this report are based on preliminary plans. The geolechnical consultant should review the final construction plans and specifications in order to confirm that the general intent of the recommendations contained in this report have been implemented into the final construction documents. Recommendations contained in this report may require modification or additional recommendations may be necessary based on the final design. ' 1.7 GEOTECHNICAL OBSERVATION AND TESTING It is recommended that inspection and testing be performed by the geotechnical consultant during the following stages of construction: • Grading operations • Excavations and backfilling for utility trenches • Placement of compacted fill • When any unusual subsurface conditions are encountered 6.0 CLOSURE This report is intended for the use by Willdan Engineering and its consultants for design and construction associated with the proposed Sanitary Sewer Line Relocation project in the City of San Bernardino, California, at the location indicated on Figure I, Site Location Map. The findings and recommendations contained in this report are based on the results of field investigation, laboratory tests, and engineering analyses, combined with an extrapolation of subsurface conditions between and beyond the boring locations. II Proposed Sanitary Sewer Line Relocation City of San Bernardino,California Willdan Project No. 17349-4004 Services performed by Willdan Geotechnical have been conducted in accordance with generally accepted professional geotechnical engineering principles and practices at this time. No other representation,express or implied, and no warranty or guarantee is included or intended. Geotechnical Engineering is one of the newest divisions of Civil Engineering. This branch of Civil Engineering is constantly improving as new technologies and understanding of earth sciences advance. Although your site was analyzed using appropriate and current techniques and methods, undoubtedly there will be substantial future improvements in this branch of engineering. In addition to advancements in the field of Geotechnical Engineering, physical -- changes in the site due to site clearing or grading activities, new agency regulations, or possible changes in the proposed structures or development after issuance of this report will result in the need for professional review of this report. Updating or revisions to the recommendations report, and possibly additional study of the site may be required at that time. In light of this, the Owner should be aware that there is a practical limit to the usefulness of this report without critical review. Although the time limit for this review is strictly arbitrary, it is suggested that two years be considered a reasonable time for the usefulness of this report. 7.0 REFERENCES American Society for Testing and Materials (ASTM), 2009.Annual Book of Standards: Soil and Rock.Vol. 04.08.

The scope of work included the following: • Review of locally and easily available published and unpublished soils, geologic, and seismologic reports and data for the area (see References in Appendix 'C'), including geotechnical and geologic reports prepared by Hilltop Geotechnical Inc. and C.H.J. Incorporated (Reference Nos. 1 and 2 noted on the cover sheet of this report) flood hazard maps, well data, etc. to ascertain soils, geologic, and hydrologic conditions of the area. • Meetings and telephone conversations with the client and/or representatives of the client. • Stereographic aerial photo analysis of the site and surrounding vicinity. Yr • Site reconnaissance. _P • Subsurface exploration by means of limited number of borings to characterize earth material,geologic,and groundwater conditions that could influence the proposed development. • Sampling of on-site earth materials from the exploratory excavations. • Laboratory testing of selected earth material samples considered representative of the subsurface conditions to determine the engineering properties and characteristics. r • Define the general geology of the subject site and evaluate potential geologic hazards which would have an effect on the proposed site development. • Determine seismic classification of the site to meet the latest requirements of the 2001 California Building Code (CBC). • Engineering analysis of field and laboratory data to provide a basis for geotechnical conclusions and preliminary recommendations regarding site grading and foundation, floor slab, retaining wall, pavement, etc. design parameters. HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page 3 1, � . • Preparation of this report to present the geotechnical and geologic conclusions and recommendations for the proposed site development. I . jThis report presents our conclusions and/or recommendations regarding: • The geologic setting of the site. • Potential geologic hazards (including landslides, seismicity, faulting, liquefaction potential, etc.) • General subsurface earth conditions. • Presence and effect of expansive, collapsible, and compressible soils. i • Groundwater conditions within the depth of our subsurface study. • Preliminary grading considerations. • Preliminary foundation considerations. 1 • Preliminary soil corrosion evaluation. • Preliminary pavement recommendations. 1 • Recommendations for additional field and laboratory studies. 1 The scope of work performed for this report did not include any testing of soil or groundwater for environmental purposes, an environmental assessment of the property, or opinions relating to the possibility of surface or subsurface contamination by hazardous or toxic substances. This study was prepared for the exclusive use of City of San Bernardino, Economical Development Agency and their consultants for specific application to the proposed 10-story office building in accordance with generally accepted HILLTOP GEOTECHNICAL, INC. 665-807.1 September 19, 2007 Page 4 3 standards of the geotechnical and geologic professions and generally- accepted geotechnical(soil and foundation)engineering principles and practices at the time 3 this report was prepared. Other warranties, implied or expressed, are not made. Although reasonable effort has been made to obtain information regarding geotechnical/geologic and subsurface conditions of the site, limitations exist with respect to knowledge of unknown regional or localized off-site conditions which may have an impact at the site. The conclusions and recommendations presented in this report are valid as of the date of this report. However, changes in conditions of a property can occur with passage of time, whether they are due to natural processes or to works of man on this and/or adjacent properties. If conditions are observed or information becomes available during the design and construction process which are not reflected in this report,Hilltop Geotechnical, Inc., as Geotechnical / Geologic Consultant of record for the project, should be r notified so that supplemental evaluations can be performed and conclusions and recommendations presented in this report can be modified or verified in writing as r necessary. Changes in applicable or appropriate standards of care in the geologic / geotechnical professions occur, whether they result from legislation or the r broadening of knowledge and experience. Accordingly, the conclusions and recommendations presented in this report may be invalidated, wholly or in part, by changes outside the influence of the project Geotechnical/Geologic Consultant which occur in the future. r • PREVIOUS SITE STUDIES Prior to this report,a previous subsurface exploration and laboratory testing report has been performed on the subject site for the existing parking lot development. The results of that study was presented in the Reference Nos. 2 report noted on the cover page of this report. The results of the previous study correspond with the HILLTOP GEOTECHNICAL, INC. ..�-+ 665-1307.1 September 19, 2007 Page 5 results of this study, recognizing the normal variations in subsurface materials within natural alluvial deposits and man made fills on the site. The information presented in the reference report is not repeated herein. However, reference is made to inform the reader of the existence of the report. 1 PROJECT DESCRIPTION/ PROPOSED DEVELOPMENT As part of our study,we have discussed the project with Mr. Collin Strange of City of San Bernardino,Economic Development Agency,the client for the project. We have also been provided with the Reference No. 3 through 5 plans for the subject site noted on the cover page of this report. In addition, we have also reviewed the Reference Nos. 1 and 2 reports which were previously prepared for ' the adjacent Meadowbrook Park site and the existing parking lot located on the north portion of the subject site, respectively. 1 Based on information presented to this firm, it is our understanding that the proposed project will consist of a new 10-story office building with associated hardscape (i.e., sidewalks, patios, curbs and gutters, etc.), and paved parking and driveway areas. The building is currently proposed to have a 25,000 to 30,000 square foot footprint. The type of construction of the building, the structural loading, and building location are not known at this time. Large foundation loads are anticipated for the proposed building. Grading is anticipated to consist of a cut-and-fill operation. Existing site topography suggests typical cuts and fills of 10 feet or less will be required to achieve finish site grades. Cut and fill slopes of than 5.0 to 10 feet in vertical height and 2:1 (Horizontal to Vertical)inclination are also anticipated for the development of the site. Some subterranean construction may be needed for the development of the project (i.e., basements, elevator pits, mechanical rooms, etc.). Minor, low height, retaining walls may also be required to establish landscape, parking, or driveway areas for the proposed development. w HILLTOP GEOTECHNI CAL, INC. 665-B07.1 September 19, 2007 Page 6 1 The above project description and assumptions were used as the basis for the field exploration, laboratory testing program, the engineering analysis, and the conclusions and recommendations presented in this report. Hilltop 1 Geotechnical, Inc. should be notified if structures, foundation loads, grading. and/or details other than those represented herein are proposed for final development of the site so a review can be performed, a supplemental evaluation made, and revised recommendations submitted, if required. FIELD EXPLORATION AND LABORATORY TESTING The field study performed for this report included a visual reconnaissance of existing surface conditions of the subject site. A study of the property's subsurface condition was performed to evaluate underlying earth strata and the presence of groundwater. Surface and subsurface conditions were explored on August 7 and 8, 2007. The subsurface exploration consisted of excavating five (5) exploratory borings on ' the subject property. The approximate locations of the exploratory excavations are shown on the `Exploratory Excavation Location Plan,' Plate No. 1, presented in Appendix 'A.' The exploratory excavations were observed and logged by a representative of Hilltop Geotechnical, Inc. The results are presented on the `Subsurface Exploration Log;Plate Nos. 3a through 7b,presented in Appendix`A: A more detailed explanation of the field study which was performed for this report ' is presented in Appendix 'A.' Relatively undisturbed ring samples and representative bulk samples of on-site fill and natural earth materials were collected during the field exploration and HILLTOP GEOTECHNICAL, INC. ILI 665-1307.1 September 19, 2007 Page 7 returned to the laboratory for testing. Laboratory tests were conducted to evaluate the index and engineering properties of on-site earth materials and included in-situ dry density and moisture content tests, expansion index tests, soluble sulfate and chloride tests, chemical and electrical resistivity tests, sieve analysis tests, maximum dry density/optimum moisture content relationship tests, direct shear tests, and consolidation tests. A more detailed explanation of laboratory tests performed for this study and test results are presented in Appendix`A.' FINDINGS SITE DESCRIPTION The subject property comprises approximately 10 acres and was rectangular in shape. The subject property is located southeast of the intersection of 3rd Street and Arrowhead Avenue in the City of San Bernardino, San Bernardino County; 1 California. The subject property is bounded by 3`d Street to the north, Arrowhead Avenue to the west, 2"d Street to the south, and the Meadowbrook Park to the east. The immediate area of the subject site was almost flat. The Warm Creek Channel runs through the southeast portion of the site. At the time the field exploration was made, the surface of the site was firm. At the time of the field study, an asphalt concrete parking lot was present in the north portion of the site. Utilities consisting of electric, sewer, water, as well as ' other unknown underground lines, were observed to be present on the site and as well as in the adjacent existing street right-of-way. Other underground, and ' overhead utilities were not observed on the subject site but are assumed to be present in the adjacent existing street right-of-ways. HILLTOP GEOTECHNICAL, INC. 665-1307.1 September 19, 2007 Page 8 At the time of the field study, vegetation across the site was light and consisted of seasonal native grasses, weeds, brush, and undergrowth and a few randomly located trees in the southern portion of the site. AERIAL PHOTOGRAPHS Aerial photographs from San Bernardino County Flood Control were examined for information pertaining to past development and grading of the subject property. In the photographs,numerous commercial and/or industrial buildings were present on the subject site. Of the thirteen structures visible north of the creek channel, at least six of them were large enough that elevators may have been used, and they may have had significant basements. Nearly the entire site, except for the Warm Creek channel, was developed. A railway line crossed onto the site in the middle of the west side of the property, then curved northeastward and exited the site near the northeast property corner. Seven (7) buildings, five (5) of which were located along 3`d Street, were visible north of the railway line. One (1) large building and four (4) smaller structures were located immediately south of the railway line, in the western portion of the property. Material storage areas and parking lots occupied most of the areas between buildings. One (1) small building was located immediately adjacent to the north edge of Warm Creek, and two (2) smaller structures, which appeared to be residential, were located to the south of the channel. Most of the on-site area was occupied by buildings or pavement. Vegetation, including trees,was observed only around two (2) buildings, in the northeast corner of the site, along the creek ' channel, and surrounding the residential structures in the southeast corner of the site. None of these structures remained on-site at the time the field study was performed for this report. r� r HILLTOP GEOTECHNICAL, INC. 665-1307.1 September 19, 2007 Page 9 The stream, labeled `Warm Creek', which crosses onto the subject site from the east, was re-channeled southward prior to 1955. The channel was moved apparently to consolidate and enlarge buildable area on the subject property. The original channel location was filled with an unknown depth of artificial fill. Boring No. B-3 appeared to be located within the original stream channel location. ENGINEERING GEOLOGIC ANALYSIS Regional Geologic Setting San Bernardino and its namesake valley lie near the northern margin of the Peninsular Ranges Geomorphic Province, one (1) of 11 provinces recognized in California. Geomorphic provinces are topographic-geologic groupings of convenience based primarily on landforms, characteristic lithologies, and late Cenozoic structural and geomorphic history. The Peninsular Ranges encompass • southwestern California west of the Imperial-Coachella Valley trough and south of the elevated terraces of the San Gabriel, San Bernardino, and Santa Monica Mountains. Most of the province lies outside of California, continuing south to include much of the Baja California Peninsula. The province is characterized by youthful, steeply sloped, northwest-trending, elongated ranges and intervening valleys. In gross aspect, average elevations across the province rise slowly to the east, usually culminating in abrupt escarpments near the eastern margin. 1 Approaching the northern edge of the province, however, several anomalously flat and low basins stretch from the San Bernardino region to western Los Angeles. These basins result from the geometry of fault junctures and tectonic interaction with the adjacent Transverse Ranges. ' Structurally, the bulk of the Peninsular Ranges province is composed of a number of relatively stable crustal blocks bounded by active strike-slip faults of the San Andreas transform system. Although some folding and minor faulting has r HILLTOP GEOTECHNICAL, INC. a 9 665-B07.1 September 19, 2007 Page 10 . occurred within the blocks,intense structural deformation and earthquake activity are mostly limited to block margins. The anomalous east-west trending San Bernardino Valley itself is defined by bounding faults that form a small. irregularly-shaped block bounded by the San Andreas fault to the northeast, the San Jacinto fault to the southwest, and an arcuate set of sometimes obscure faults trending southwest through the Yucaipa, Redlands, and Loma Linda areas. The San Bernardino Valley is not an erosional feature;it is a deep structural basin that is believed to be slowly subsiding in response to the transference of slip from the San Jacinto fault to the San Andreas fault. The Peninsular Ranges province contains a diverse array of metamorphic, sedimentary, and igneous rocks. Inland, the province is dominated by crystalline basement rocks. In general, the metamorphic rocks represent highly-altered host rocks formed during emplacement of very large,plutonic masses of varying granitic rock composition. Closer to the coastline, younger rocks include thick sequences of marine and non-marine, clastic, sedimentary rocks ranging from claystones to conglomerate. These sedimentary formations generally are of late-Mesozoic and Tertiary age. The Winchester area is defined by isolated, small mountain ranges ' composed of granitic basement rock separated by broad,flat-lying, alluvium-floored valleys. The general geology in the area surrounding the subject site is shown on the `Regional Geology Map,' Figure No. 2. Quaternary alluvium forms several massive fans extending from the mouths of Lytle Creek, Cajon Creek, and Santa Ana Canyons. Smaller alluvial fans extend from smaller canyons to the north and northeast of the subject site. The predominant source of sedimentary material for the subject site likely is the Santa ' Ana Canyon,but material from several sources appear to be present. The inferred a.

Local Subsurface Conditions .�� Earth Materials Description: Presented as follows are brief descriptions of the earth materials encountered in the exploratory excavations. More detailed descriptions of encountered earth materials are presented on the 'Subsurface Exploration Log; Plate Nos. 3a through 7b, presented in Appendix'A' The earth material strata, as shown on the logs, represent conditions at the actual exploratory excavation locations. Other variations may occur beyond and/or between the excavations. Lines of demarcation between earth materials on the logs represented the approximate boundary between the material types;however, the transition may be gradual. The site materials encountered during the field exploration were identified as man- made fills (at), young alluvial valley deposits (Qya), and very young alluvial deposits in active washes (Qw). r. From the ground surface to depths of approximately 2.0 to 13 feet at the location of borings B-1 through B-5, soils were classified as man-made fill. Fill materials generally consisted of silty fine to coarse sand(SM),silty fine to medium sand with a trace clay and a trace fine gravel (SM), sandy clay (CL), gravely fine to coarse sand (SP), and silty fine sand (SM). Fill soils were brown or dark brown in color, moist, and loose to medium dense in relative density or stiff in consistency. The fill is considered to be undocumented since no reports were made available for review. HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page 12 Young alluvial valley deposits were encountered underlying the fill soils in borings ' B-1, B-2, and B-4. The alluvial deposits generally consisted of slightly silty fine to coarse sands (SP/SM), silty fine sand (SM), fine to coarse sand with a trace clay lenses and a trace gravel (SP), slightly silty fine sand (SP/SM), sandy gravel with a trace silt (GP), fine sandy clay (CL), fine sandy silt (ML), and gravely fine to coarse sand (SP). These strata were brown or light brown in color, moist to wet, and loose to very dense in relative density or stiff to hard in consistency. Very young alluvial wash deposits were encountered underlying the fill soils in borings B-3 and on the surface at the location of boring B-5. The wash deposits generally consisted of silty fine sand (SM), fine sand (SP), slightly silty fine to coarse sand with a trace gravel (SP/SM), slightly silty, gravely fine to coarse sand (SP/SM), silty fine to coarse sand with a trace gravel (SM), and fine to coarse sand go (SP), and silty fine sand (SM). These strata were brown, light brown, yellow- brown, or gray in color, moist to wet, and loose to very dense in relative density. ' Groundwater: Groundwater was encountered at a depth of 45.5 to 46 feet below the existing ground surface at the location of borings B-3 and B-5 at the time the field study was performed for this report. A review of available groundwater contour maps indicated the historical minimum depth to groundwater in the general area has been approximately 10 feet (1991, Matti, J.C. and Carson, S.E.). The area of the proposed project is near downtown San Bernardino, an area that has recorded historically high groundwater levels. Issues of groundwater infiltration into building basements have been recorded within one-quarter mile of the subject site. During the late 1880s, a marsh was mapped within one (1) to r HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page 13 two (2) city blocks to the north of the project area (CDMG 1976). While the marsh was not shown on the project site,presence of a marsh nearby implies groundwater to be present near the ground surface. 1 Surface Water: No surficial water was observed in the higher elevations of the subject property at the time the field study was performed for this report. Site Variations: Based on results of our subsurface exploration and experience, variations in the continuity and nature of surface and subsurface conditions should be anticipated. Due to uncertainty involved in the nature and depositional characteristics of earth materials at the site, care should be exercised in extrapolating or interpolating subsurface conditions between and beyond the exploratory excavation locations. Groundwater observations were made in the exploratory excavations at times and under conditions stated on the boring logs. These data have been reviewed and interpretations made in the text in other sections of this report. However,it should be noted that fluctuations in levels of groundwater, springs, and/or perched water may occur due to variations in precipitation, temperature, and other factors. Faulting and Regional Seismicity The site is situated in an area of active and potentially active faults, as is most of metropolitan southern California. Active faults present a variety of potential risks to structures, the most common of which are strong ground shaking, dynamic densification, liquefaction, mass wasting, and surface rupture at the fault plane. Generally speaking, the following four (4) factors are the principal determinants of seismic risk at a given location: HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page 14 • Distance to seismogenically capable faults. iThe maximum or"characteristic"magnitude earthquake for a capable fault. • Seismic recurrence interval, in turn related to tectonic slip rates. • Nature of earth materials underlying the site. Surface rupture represents the primary potential hazard to structures built on an active fault zone. Reviews of official maps delineating State of California earthquake fault zones(California Department of Conservation,Division of Mines and Geology, Effective January 1, 1977, State of California Special Studies Zones, San Bernardino South Quadrangle, Revised Official Map, Scale i1:24,000) indicated the site is not located within a zone of mandatory study for active faulting. Additionally, no known active faults trend toward the subject property. The San Jacinto fault (San Bernardino and San Jacinto Valley 1 Segments) are within approximately 3.9 and 10.7 kilometers to the southwest and south of the site, respectively. The San Andreas fault (San Bernardino Segment) passes within approximately 9.1 kilometers to the northeast of the of the site. Dibblee (2004) places a buried and queried trace of the Glen Helen Fault approximately 0.7 kilometers to the northeast of the subject site. Accordingly, the potential for surface fault rupture on this site is considered to be very low. Ground shaking is judged to be the primary hazard most likely to affect the site, based upon proximity to four (4) regionally significant, active faults: the San Bernardino and San Jacinto Valley segments of the San Jacinto fault, the San Bernardino Segment of the San Andreas fault, and the Cucamonga fault. Other significant fault zones, including the North Frontal fault, the Elsinore fault, and several fault zones in the high desert area are located at distances exceeding the five listed faults. Greater distances, lower slip rates, and lesser maximum w ' HILLTOP GEOTECHNICAL, INC. _ Page 15 665-B07.1 September 19, 2007 magnitudes indicate much lower risk to the site from the latter fault zones than the four (4) closest faults, including the regionally significant San Andreas fault. Characteristics of the major active fault zones selected for inclusion in analysis of strong ground shaking are listed in the following table: Distance Fault Slip Reference Fault Fault Zone from Site Length Rate Earthquake Type" ' (km)' (km)' (mm/y02 (��m..)L San Jacinto 3.9 36 12.0 6.7 A (San Bernardino Segment) rJacinto Andreas 9.1 103 24.0 7.5 A rdino Segment) Jacinto 10.7 43 12.0 6.9 A Valley Segmentamonga 16.1 28 5.0 6.9 B e,Tho mas F.,2000,Preliminary Fault-Data for EQFault,EQSearch and FriskSP lake,Thomas, F., Computer Services and Software, Users Manuals, FriskSP u.

Deterministic analyses of the hazard of ground shaking at the site were considered for reference earthquakes on each of the regional faults listed above. The San Jacinto fault (San Jacinto Valley and San Bernardino Segments) are 6.9 and 6.7 events, respectively,with 100-percent, right-lateral, strike-slip displacement. For the San Andreas fault (San Bernardino Segment), the modeled event is a single- segment event, producing a 100-percent, right-lateral, strike-slip, moment- magnitude 7.5 earthquake. The Cucamonga fault is the closest thrust fault associated with uplift of the Transverse Ranges and was modeled as a 6.9 moment- magnitude source with a reverse-slip (45 N) displacement. HILLTOP GEOTECHNICAL, INC. 665-1307.1 September 19, 2007 Page 16 Probabilistic seismic hazard maps and data files jointly prepared by the California Geological Survey(CGS)and the U.S.Geological Survey(USGS) assign a 10-percent likelihood that horizontal ground acceleration of approximately I 0.83g will occur at this site within the next 50 years. This data was available at the CGS `Probabilistic Seismic Hazards Mapping Ground Motion Page' (http://www.conservation.ca.gov/cgs/rghm/pshamap/pshamain.asp). The probabilistic hazard maps were calculated for alluvial sites such as the subject property. Actual shaking intensities at the site from any seismic source may be substantially higher or lower than estimated for a given earthquake magnitude, due to complex and unpredictable effects from variables such as: i • Near-source directivity effects. • Direction, length, and mechanism of fault rupture (strike-slip, normal, reverse). • Depth and consistency of unconsolidated sediments. • Topography. • Geologic structure underlying the site. • Seismic wave reflection, refraction, and interference. Secondary Seismic Hazards Secondary hazards include induced landsliding or mass wasting, liquefaction, flooding (from ruptured tanks and reservoirs, surface oscillations in larger lakes, or seismic sea waves), and subsidence as a result of soil densification. Landsliding and liquefaction susceptibility maps have been prepared for much of coastal Los Angeles and Orange County, California by the DMG. However, this area of San Bernardino County, California is not presently scheduled for mapping by the State. HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19. 2007 Page 17 Accordingly, as of the date of this report, the site has not been identified or excluded from a State-delineated zone of mandatory study for either landsliding or liquefaction. Liquefaction: Liquefaction is a phenomenon in which cohesionless, saturated, fine-grained sand and sandy silt soils lose shear strength due to groundshaking. 1 The subject site is located within an area designated by the County of San Bernardino as having a'High'potential for liquefaction(San Bernardino County Planning Department, San Bernardino, Official Land Use Plan, General Plan, Geologic Hazard Overlay, Sheet FH30 C, San Bernardino South). iLiquefaction is a phenomenon where a sudden large decrease of shearing resistance takes place in fine grained cohesionless and/or low plasticity cohesive ' soils due to the cyclic stresses produced by earthquakes causing a sudden, but temporary, increase of porewater pressure. The increased porewater pressure occurs below the water table, but can cause propagation of groundwater upwards into overlying soil and possibly to the ground surface and cause sand boils as ' excess porewater escapes to the surface when groundwater is shallow. Potential hazards due to liquefaction include significant total and/or differential settlements of the ground surface and structures as well as potential collapse of structures due to loss of support of foundations. Laboratory testing and soil condition analyses, at sites where liquefaction has occurred, have shown that the soil types most susceptible to liquefaction are saturated, fine sand to sandy silt. These soils derive their shear strength from intergranular friction and do not drain quickly during earthquakes. Published studies and field and laboratory test data indicate that coarse sands, gravelly sands, and silty or clayey sands are considerably less vulnerable to liquefaction. To a large extent, the relative density of sands also HILLTOP GEOTECHNICAL, INC. 665.1307.1 September 19, 2007 Page 18 controls the liquefaction susceptibility for a given number of cycles and acceleration levels during a seismic event. Other characteristics such as confining pressure and the stresses created within the soil during a seismic event also affect the liquefaction potential of a site. Liquefaction of soil does not generally occur below depths of 40 to 50 feet below the ground surface due to confining pressure at that depth. Moreover, saturated fine sands with relative densities of approximately 70 percent or greater are not likely to liquefy, even under very 1 severe seismic events. Liquefaction Program: A formal liquefaction analysis was performed as part of this study using the LiquefyPro computer program. This program is based on the most recent publications of the NCEER Workshop and SP117 Implementation. . The liquefaction potential of the alluvium identified in the exploratory excavations was evaluated in general accordance with procedures proposed in published references (Seed and Idriss, 1971: Tokimatsu, 1987; Youd and Idriss, 1997). Input Parameters: Faultina and Reaional Seismicity: The "Faulting and Regional Seismicity" section of this report addressees the major fault systems and ground motion parameters which would effect the subject site. An earthquake of magnitude M7.5 and a calculated peak ground acceleration of 0.838 (10 percent probability of exceedance in 50 years) per the USGS `Probabilistic Seismic Hazards Mapping Ground Motion Page' (www.conservation,ca.gov/cgs/rghm/pshamapmain.html) were used in the liquefaction evaluation. Groundwater: A historic high groundwater depth of 10 feet below the existing ground surface at the subject site was also used in the evaluation as required in California Department of Conservation, Division of Mines and Geology, HILLTOP G EOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page 19 1997, Guidelines for Evaluating and Mitigating Seismic Hazards in California, Special Publication 117. It should be noted that the depth of groundwater was encountered at depths of 45.5 to 46 feet below the existing ground surface at the boring locations at the time the field study was performed for this report. Grain Size: The quantity of soil passing the #200 sieve were performed on samples obtained from the field study. The test results are presented on the 'Summary of Laboratory Test Results,' Plate Nos. 10 and 11, presented in Appendix `A.' 1 Blow Counts: Standard Penetration Tests (SPT)were performed during the field study. Field blow counts are presented on the 'Subsurface Exploration Log,' Plate . Nos. 3a through 7b, presented in Appendix `A.' The field SPT blow counts were corrected for sampler type, effective overburden, energy ratio, rod length, and the 1 blow counts were adjusted to a"standardized"penetration resistance values- (N,)cu for use in the liquefaction analysis. Relative Density: The relative density of the subsurface materials was determined based on the SPT blow counts. The moist and saturated unit weights of soils used in the liquefaction analysis were interpreted from tables in NAVFAC Design Manual 7.01, September 1986. Liquefaction Analyses: Soil strata above the considered groundwater table elevations below ground surface were not included in the liquefaction analysis. The Cyclic Stress Ratio to cause liquefaction for a M7.5 earthquake was calculated. The earthquake induced Cyclic Stress Ratio (CSR) was calculated and the factor of safety determined for the various earth strata. 'r HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page 20 Results and Conclusions: A Factor of Safety against the occurrence of liquefaction greater than 1.3 is considered to be an acceptable level of risk for non- liquefiable materials for the evaluation based on the guidelines presented in California Department of Conservation, Division of Mines and Geology, 1997, Guidelines for Evaluating and Mitigating Seismic Hazards in California, Special Publication 117. The results of the liquefaction analysis are shown on Plate Nos. 19 through 24, `Liquefaction Analysis,'presented in Appendix`C.' The results are also summarized in the table below.

The Reference No. 1 `Report of Geotechnical / Geologic Feasibility Study', also indicates that the Meadowbrook Park site located on the east side of the subject site has a liquefaction potential. f HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page 21 aA total liquefaction settlement of up to 3.8 inches was estimated based on the liquefaction analysis under the peak ground acceleration and maximum earthquake condition. The differential settlements due to liquefaction are expected to be approximately one-half of the total settlement because of the presence of deep alluvial sediments and uniformity of soil layers within the proposed structures. Based on data contained in"Liquefaction of Soils During Earthquakes"published by the Committee on Earthquake Engineering, Commission on Engineering and Technical Systems, National Research Council, 1985, the probability of ground damage at the surface of the subject site as a result of liquefaction is high due to the thickness of soils with a liquefaction potential verses the thickness of overlying, non-liquefiable soils, as shown on Plate No. 25, 'Ground Damage Potential,' presented in Appendix `C' for a historical groundwater depth of 10 feet below the go surface. Based on data contained in "Liquefaction of Soils During Earthquakes" published by the Committee on Earthquake Engineering, Commission on ' Engineering and Technical Systems, National Research Council, 1985, the probability of ground damage at the surface of the subject site as a result of liquefaction is low due to the thickness of soils with a liquefaction potential verses the thickness of overlying, non-liquefiable soils, as shown on Plate No. 25, `Ground Damage Potential,' presented in Appendix `C' for the current groundwater depth of 37 to 48 feet below the surface. Therefore, a deep foundation system founded at depth of greater than 50 feet below existing site grades and/or other types of site / ground remediation procedures, such as pressure grouting, sand or stone columns, wick drains, etc. will be needed to develop the project. Once the location and footprint of the proposed structure is finalized on the subject site, additional borings are recommended to be performed to more precisely define the foundation system and depth, ground • HILLTOP GEOTECHNICAL, INC. 1 I X, 665-1307.1 September 19, 2007 Page 22 , . modification procedures, geotechnical design parameters, etc. for the design and iconstruction of the proposed development. Seismically Induced Settlement in Dry Sand: Loose, sandy soils subjected to moderate to strong groundshaking can experience settlement. Experience from the Northridge Earthquake indicates that structural distress can result from such seismic settlement. Based upon results of this study, the subject site is underlain by fine-grained, alluvial soils. A formal dry sand settlement analysis was performed using LiquefyPro the computer program. This program is based on the most recent publications of the NCEER Workshop and SP117 Implementation. An estimated total settlement of up to 7.5 inches was calculated for the upper 50 feet of the alluvium underlying the subject site under intense seismic shaking based on an earthquake of magnitude M„.= 7.5, a probabilistic peak ground acceleration(PGA)of 0.82g, and the current groundwater depth of 45.5 to 46 feet below the existing site grades. The results of the analysis are shown on Plate Nos. 26 through 28, 'Earthquake Induced Settlement of Dry Sands,' presented in Appendix'C.' Therefore, significant settlement of the site due to intense seismic shaking is considered to be a significant design consideration for the development of the project. Therefore, a deep foundation system and/or other types of site / ground 4 remediation procedures will be needed to develop the project. i Seiching: Seiching involves an enclosed body of water oscillating due to groundshaking, usually following an earthquake. Lakes and water towers are typical bodies of water affected by seiching. However, the site does not appear to HILLTOP GEOTECHNICAL, INC. 1 665-B07.1 September 19, 2007 Page 23 i be within the influence of large bodies of water and, as such, seiching should not be considered a hazard in the area. Tsunamis: Because of the inland geographic location of the site,tsunamis are not considered a hazard. Lurching: Lurching is a phenomena in which ground cracking and/or secondary faulting occurs as a result of groundshaking. Generally,lurching primarily occurs in the immediate vicinity of faulting or within typical building setback zones or "No Human Occupancy"zones. No evidence of faulting was encountered on the site and although the potential for lurching cannot be entirely ruled out,the likelihood ',6"' for lurching to impact the site is considered to be low. OTHER GEOLOGIC HAZARDS Flooding Flood Insurance Rate Maps (FIRM) were compiled by the Federal Emergency Management Agency (FEMA) for the Flood Insurance Program and are available for most areas within the United States. The attached 'Flood Hazard Map,' Figure No. 3, is based on FIRMs provided by FEMA and is specific to the area around the subject site. The'Flood Hazard Map'indicates that the site is not located within a 100-year flood zone. However, the Warm Creek Channel is located on the subject site. Therefore, the possibility of flooding of the site should be verified by the project Civil Engineer if it is considered a design factor. +r HILLTOP GEOTECHNICAL, INC. 0 7 aa X s a Zone X a 0 Ro w i g z EAST 4TH STREET 0 s - Sitz z T STREET WEST COURT STREET LAST COURT STREET L. e.

CONCLUSIONS AND RECOMMENDATIONS GENERAL The conclusions and recommendations presented in this report are in part, based on information provided to this firm, the results of the field and laboratory data ' obtained from five (5) exploratory excavations located on the subject property, experience gained from work conducted by this firm on projects within the general f vicinity of the subject site, the project description and assumptions presented in the`Project Description/Proposed Development'section of this report,engineering analyses, and professional judgement. Based on a review of the field and laboratory data and the engineering analysis,the proposed development is feasible from a geotechnical / geologic standpoint. The conclusions provided in this summary should be considered preliminary and subject to revision when additional design criteria has been developed and a more detailed geotechnical study can be performed. PRELIMINARY GRADING CONSIDERATIONS The average in-situ moisture contents and in-situ dry densities of the upper 10 feet of the near-surface fill and alluvial materials on the subject site suggests that the soils have an average relative compaction of less than 90 percent. HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page 25 The field observations indicate that up to 13 feet of material present on the subject site was an undocumented fill material. The artificial fills on the site are also considered loose and compressible. pThe near-surface fill and alluvial soils present on the subject site exhibit a `Low' expansion potential in accordance with Table 18-I-B, 'Classification of Expansive Soil,' in the 2001 California Building Code (CBC). Therefore, some remedial grading consisting of removals and replacement will have to be performed within loose, compressible, artificial fill and loose, near- surface alluvial materials in the area of proposed structural fills, structures, exterior hardscapes, and/or pavement. However, depending on the utilization of a basement in the proposed building, the use of a structural ground level floor slab for the structure, and/or other combinations of structural design parameters and architectural features may alleviate the requirements for deep overexcavation and replacement on the subject site. Excavation and trenching within the subject property to the depths anticipated for the proposed development is anticipated to be relatively easy in the near-surface undocumented fills and alluvial materials on the subject site and should be accomplished with conventional earth-moving equipment since the drill rig equipped with flight augers was able to penetrate to the indicated depths. Materials were not encountered or are anticipated that would require heavy ripping or blasting to excavate. It is not anticipated that a significant amount of oversized rock material (i.e., 3.0 inches in greatest dimension) will be generated during the removal and replacement process within the alluvial materials which will require special handling during the development of the site. HILLTOP GEOTECHNICAL, INC. 665-1307.1 September 19, 2007 Page 26 3 In general, the on-site earth materials present below any topsoil and/or highly organic materials are considered satisfactory for reuse as fill. Fill materials should be free of significant amounts of organic materials and/or debris and should not contain rocks or clumps greater than 3.0 inches in maximum dimension. CBC SEISMIC DESIGN CRITERIA The California Building Standards Commission, 2001 California Building Code (CBC), California Code of Regulations, Title 24, Part 2, Volumes 1 and 2, contains substantial revisions and additions to previous editions in the earthquake engineering section in Chapter 16, Division IV, 'Earthquake Design.' Concepts contained in the updated code which will be relevant to construction of this project include: • Seismic Source Type A, B, C (Type Fault) Defined by Mme. z7M„ or <6%M,,; and fault slip rate i5 or s2 mm/yr. ?, • MM„ (Maximum Magnitude) r. Defined using moment magnitude scale, M,,. • Soil Profile Types Categorizing the upper 30 meters(±100 ft.)of earth materials into one of the soil profile types Sa, Ss, Sc, SD, SE, and SF that are based on average shear wave velocities, Standard Penetration Test blow counts,or undrained shear strength. • Near Source Factors Proximity to the Type `A,' B,' or'C' fault or seismic source type for: Na (Acceleration): Distance s2, s5, or Z10 km. so N, (Velocity): Distance s 2, s 5, s 10, or z 15 km. ,,,,� • Seismic Coefficients Coefficients for acceleration (C.) and velocity (C) that are based on 'Soil Profile Type' and the 'Near Source Factors' Na and N, for a 'Seismic Zone Factor' Z = 0.4. M WWI- rw HILLTOP GEOTECHNICAL, INC. .., 665-1307.1 September 19, 2007 Page 27 ® Based on our understanding of local geologic conditions and limited in-situ penetration tests performed for this study, the Soil Profile Type judged applicable to this site is Sp, generically described as a 'Stiff Soil' profile per Table 164, 'Soil Profile Types,' in the 2001 CBC with an Shear Wave Velocity of 600 to 1,200 feet/second (180 to 360 m/s) or an average Standard Penetration Test value of 15 to 50 blows per foot of penetration in the upper 100 feet (30.48 m) of the site. The property is located within Seismic Zone 4 per Figure 16-2,'Seismic Zone Map of the United States,' in the 2001 CBC. A 'Seismic Zone Factor' Z = 0.4 should be used in the seismic design per Table 16-I,'Seismic Zone Factor Z,'in the 2001 CBC.

HILLTOP GEOTECHNICAL, INC. 665-1307.1 September 19, 2007 Page 28 Since the 2001 CBC specifies that the highest calculated Near-Sourpo Factors be Q utilized for design, the San Jacinto (San Bernardino Segment) fault, the closest fault to the subject site, becomes the controlling seismic source for this site. Final M selection of a "design" acceleration should be made by the project Structural Consultant and should be reflective of the building type,expected seismic response, adopted codes, and level of conservatism exercised during the design process. 1 It is noted that on January 1, 2008 the new 2007 California Building Code (CBC) will become effective. The 2007 CBC has substantial revisions to the seismic design criteria. Due to the type of structure design,the Structural Engineer for the project may also require additional seismic design criteria above and beyond the basic 2001 CBC input parameters presented above. PRELIMINARY FOUNDATION RECOMMENDATIONS Based on the exploratory excavation, field observations and laboratory test data, the subject site is underlain by undocumented fills and alluvial deposits. The near- surface fill and alluvial soils present on the subject site exhibit a "Low' expansion potential. Engineering analyses indicate that the alluvial materials on the site are subject to liquefaction at a historical groundwater depth and/orexcessive settlement of dry sands at the present groundwater depths during the design seismic event anticipated for the area. Therefore,a deep foundation system founded at depth of greater than 50 feet below existing site grades is recommended unless some site remediation procedures are adopted to limit the total settlement of the liquefiable soils and dry sandy soils. HILLTOP GEOTECHNICAL, INC. i 665-1107.1 September 19, 2007 Page 29 Once the location and footprint of the proposed structure is finalized on the subject site, additional borings and geotechnical analyses are recommended to be performed to more precisely define the foundation system and depth, ground modification procedures, geotechnical design parameters, etc. for the design and construction of the proposed development PRELIMINARY CORROSION POTENTIAL EVALUATION Bulk samples of the near surface on-site soils were obtained during the field study to evaluate the potential for soil corrosivity. Results from the tests are included in the 'Summary of Laboratory Test Results' presented in Appendix'A.' r Concrete Corrosion to Preliminary tests on samples of near-surface on-site soil material suggests a Pt.., soluble sulfate concentration of 0.002 to 0.028 percent. Soils with a water soluble sulfate (SOJ concentration in the range of 0.0 to 0.10 percent are considered to have a'Negligible' sulfate exposure to concrete which comes in direct contact with the on-site soil as defined in Table 19-A-4, 'Requirements for Concrete Exposed to Sulfate-Containing Solutions,' in the 2001 CBC. The 2001 CBC should be used to determine the type cement, the maximum water cement ratio, and the minium compressive strength to be used for normal weight concrete which comes in direct contact with the on-site soils (i.e., foundations, floor slabs, driveway slabs, sidewalks, patios, curbs / gutters, etc.). A lower water / cement ratio or higher compressive strength may be requested for design of concrete for water tightness or for protection against corrosion of embedded metallic items or freezing and thawing per Table 19-A-2, 'Requirements for Special Exposure Conditions,'in the 2001 CBC, if applicable. XJ �a HILLTOP GEOTECHNI CAL, INC. 665-1307.1 September 19, 2007 Page 30 rExperience in the southern California area has shown that even though the soils do not contain levels of soluble sulfate which would require the use of sulfate resistant cement, maximum water cement ratios, or minimum compressive strength for concrete, concrete corrosion and erosion problems still occur. These problems are the result of concentrations of soluble sulfate, chloride, and other M salts and/or acids present in groundwater,irrigation water,rainwater,andpotable water sources, and in fertilizers or soil amendments used to promote plant growth M (i.e., some domestic water sources contain levels of soluble sulfate which would be a moderate sulfate exposure to concrete which comes in contact with it). Therefore, it may be wise to use a concrete designed for a moderate exposure to sulfate per the criteria presented in Table 19-A-4,`Requirements for Concrete Exposed to Sulfate- Containing Solutions,' in the 2001 CBC that comes into contact with surface run- off or other sources of water. Higher strength, lower water / cement ratio, and denser concrete may also be effective in reducing the potential for evaporation to y. occur and preventing damage due to salt or acid exposure. Metallic Corrosion Preliminary minimum resistivity tests on samples of the near-surface on-site soil material suggest a mild corrosive environment for buried ferrous metal in direct contact with the on-site soils when the soils are moist to wet. Preliminary tests on samples of near-surface on-site soil material suggests a soluble chloride concentration of 0 to 41 parts per million (ppm). Soils with less than 300 ppm of soluble chloride are not considered to be aggressive to buried ferrous and copper r material, in direct contact with the soils. Soil pH is a general indicator of the Icorrosivity of the soils. The measured pH of samples of near-surface on-site soil material of 8.5 to 8.8 indicates a non-corrosive environment to copper and ferrous metals when in direct contact with the on-site soils. HILLTOP GEOTECHNICAL, INC. 665-1307.1 September 19, 2007 Page 31 The life of buried metals depends on type of material, thickness, and construction details_ If corrosion protection of metals in direct contact with the on-site soils is considered to be a design issue, tests should be performed at the completion of the M grading for the building pads and/or an engineer specializing in corrosion should be consulted regarding the potential damage due to corrosion. The corrosion M engineer should recommend appropriate types ofpiping and/or protective measures where needed. 10 RECOMMENDATIONS FOR ADDITIONAL STUDY Once the location and footprint of the proposed structure is finalized on the subject site, we recommend that an additional geotechnical study be performed on-site. The scope of this study should include: • Provide geotechnical design parameters for the foundation system. • Define any ground modification procedures. • More detailed site characterization with respect to proposed grading. • More detailed soil analysis. • Provide geotechnical design parameters for the retaining walls and pavement recommendations.

Ifni Do r . r a M a a i APPENDIX A 1 1 1 HILLTOP GEOTECHNICAL, INC. �.. 665-1307.1 September 19, 2007 Page A-1 FIELD EXPLORATION ■ The field study performed for this report included a visual reconnaissance of existing surface conditions of the subject site. Site observations were conducted on August 7 and 8, 2007 by a representative of Hilltop Geotechnical, Inc. A study of the property's subsurface condition was performed to evaluate underlying earth strata and the presence of groundwater. Five (5) exploratory borings were performed on the subject site on August 7 and 8, 2007. Locations of 1 the exploratory excavations were determined in the field by pacing and sighting from the adjacent existing streets and adjacent structures. Approximate locations ' of the exploratory excavations are denoted on the`Exploratory Excavation Location Plan,' Plate No. 1, presented in this Appendix. Locations of the exploratory • excavations should be considered accurate only to the degree implied by the method used in determining them. The exploratory borings were performed by using a truck-mounted drill rig equipped with 8-inch outside-diameter, hollow-stem augers. The exploratory w excavations were explored to depths ranging from approximately 49 to 50 feet below existing ground surface at the excavation locations. Bulk and relatively undisturbed samples of encountered earth materials were obtained at various depths in the exploratory excavations and returned to our laboratory for testing and verification of field classifications. Bulk samples were obtained from cuttings developed during the excavation process and represent a mixture of soils within the depth indicated on the logs. Relatively undisturbed samples of encountered earth materials were obtained by driving a thin-walled, steel sampler lined with 1-inch high, 2.413-inch inside diameter brass rings. The sampler was driven with successive drops of a 140-pound weight having a free fall of approximately 30 HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page A-2 inches. Blow counts for each successive 6.0 inches of penetration, or fraction thereof, are shown on the`Subsurface Exploration Log,' Plate Nos. 3a through 7b, presented in this Appendix. Ring samples were retained in close-fitting moisture- proof containers and returned to our laboratory for testing. Standard Penetration Tests were also performed below the groundwater in borings B-3 and B-5. The test was performed in general accordance with current American Society of Testing Materials (ASTM) D1586 procedures using a standard penetration sampler (2.0- inch outside diameter, 1.375-inch inside diameter) driven with a 140 weight dropping 30 inches. The blow counts to drive the sampler for three (3) successive 6.0 inch intervals are recorded on the`Subsurface Exploration Log,' Plate Nos. 5b and 7b, presented in this Appendix. The standard penetration resistance ('N' value) is the sum of the blow counts for the last two (2) 6.0 inch intervals. r Groundwater observations were made during, and at the completion of the excavation process and are noted on the`Subsurface Exploration Log'presented in this Appendix, if encountered. The exploratory excavations were logged by a representative of Hilltop Geotechnical, Inc. for earth materials and subsurface conditions encountered. Soil materials encountered in the exploratory excavations were visually described in the field in general accordance with the current Unified Soils Classification System (USCS), ASTM D2488, visual-manual procedures, as illustrated on the attached,simplified'Subsurface Exploration Legend,'Plate No.2,presented in this Appendix. The visual textural description, color of the soil at natural moisture content, apparent moisture condition of the soils, and apparent relative density or consistency of the soils, etc.,were recorded on the field logs. The`Relative Density' of granular soils is given as very loose, loose, medium dense, dense, or very dense and is based on the number of blows to drive the sampler. The`Consistency'of silts HILLTOP GEOTECHNICAL, INC. 665-1307.1 September 19, 2007 Page A-3 or clays is given as very soft, soft, medium stiff, stiff, very stiff, or hard and is also based on the number of blows to drive the sampler. The field log for each excavation contains factual information and interpretation of soil conditions between samples. The `Subsurface Exploration Logs' presented in this Appendix represent our interpretation of the field log contents and results of laboratory observations and tests performed on samples obtained in the field from the Mexploratory excavations. The exploratory boring excavations were backfilled with excavated earth materials and with reasonable effort to restore the areas to their initial condition before leaving the site. In an area as small and deep as a boring excavation,consolidation ' and subsidence of backfill soil may result in time, causing a depression of the excavation areas. The client is advised to observe exploratory excavation areas periodically and, when needed, backfill noted depressions. • HILLTOP GEOTECHNICAL, INC. 665-1307.1 September 19, 2007 Page A-4 LABORATORY TESTING PROGRAM Laboratory tests were performed on selected,relatively undisturbed ring and bulk samples obtained from exploratory excavations during the field study. Tests were performed in general accordance with generally accepted American Society for Testing and Materials(ASTM), State of California-Department of Transportation (CALTRANS), Uniform Building Code (UBC), or other suitable test methods or procedures. The remaining samples obtained during the field study will be discarded 30 days after the date of this report. This office should be notified immediately if retention of samples will be needed beyond 30 days. A brief wr. description of the tests performed is presented below: ■ • J CLASSIFICATION The field classification of soil materials encountered in the exploratory excavations was verified in the laboratory in general accordance with the current Unified Soils Classification System, ASTM D2488, `Standard Practice for Determination and Identification of Soils (Visual-Manual Procedures): The final classification is rr shown on the `Subsurface Exploration Log,'Plate Nos. 3a through 7b,presented in this Appendix. r IN-SITU MOISTURE CONTENT AND DRY DENSITY ` The in-situ moisture content and dry density were determined in general accordance with current ASTM D2216 (Moisture Content) and D2937 (Drive r Cylinder) procedures, respectively, for selected undisturbed samples obtained. This information was an aid to classification and permitted recognition of �►. variations in material consistency with depth. The dry density is determined in pounds per cubic foot and the moisture content is determined as a percentage of HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page A-5 the oven dry weight of the soil. Test results are shown on the 'Subsurface Exploration Log,' Plate Nos. 3a through 7b, presented in this Appendix. EXPANSION TEST Laboratory expansion tests were performed on samples of near-surface earth material in general accordance with the current ASTM D4829 procedures. In this testing procedure, a remolded sample is compacted in two (2) layers in a 4-inch 3 inside diameter mold to a total compacted thickness of approximately 1.0 inch by using a 5.5-pound weight dropping 12 inches and with 15 blows per layer. The 3 sample should be compacted at a saturation between 49 and 51 percent. After remolding, the sample is confined under a pressure of 144 pounds per square foot (psf) and allowed to soak for 24 hours. The resulting volume change due to the increase in moisture content within the sample is recorded and the Expansion Index (EI) calculated. The test results are summarized in the 'Summary of Laboratory Test Results,' Plate No. 8, presented in this Appendix. SOLUBLE SULFATE TEST The concentration of soluble sulfate was determined on samples of near-surface soil material in general accordance with current EPA 300.0 test method. The test results are summarized in the 'Summary of Laboratory Test Results,'Plate No. 8, presented in this Appendix. SOLUBLE CHLORIDE TEST it The concentration of soluble chloride was determined on samples of near-surface soil material in general accordance with current EPA 300.0 test method. The test as results are summarized in the'Summary of Laboratory Test Results,' Plate No. 9, presented in this Appendix. TE HNI AL INC. HILLTOP GEO C C , 665-1307.1 September 19, 2007 Page A-6 CHEMICAL AND MINIMUM ELECTRICAL RESISTIVITY The pH, Redox, Sulfide, and electrical resistivity for the in-situ moisture content and a saturated condition were determined for a sample of near-surface soil 1 materials. The test results are summarized in the 'Summary of Laboratory Test Results,' Plate No. 9, presented in this Appendix. SIEVE ANALYSIS The percent by weight finer than a No. 200 sieve (silt and clay content) was determined for selected samples of earth material in general accordance with current ASTM D1140 procedures. The testis performed by taking a known weight of an oven dry sample of soil material, washing it over a No. 200 sieve, and oven drying the soil retained on the No. 200 sieve. The dry weight of soil material retained on the No. 200 sieve is measured and the resulting percentage retained is calculated based on the original total dry soil sample weight. The percent passing the No. 200 sieve is determined by subtracting the percent retained from ' 100. The test results are summarized in the 'Summary of Laboratory Test Results,' Plate Nos. 10 and 11, presented in this Appendix. MAXIMUM DRY DENSITY/ OPTIMUM MOISTURE CONTENT RELATIONSHIP TEST Maximum dry density/optimum moisture content relationship determination were performed on samples of near-surface earth material in general accordance with current ASTM D1557 procedures using a 4-inch diameter mold. Samples were prepared at various moisture contents and compacted in five (5) layers using a 10- pound weight dropping 18 inches and with 25 blows per layer. A plot of the compacted dry density versus the moisture content of the specimens was i constructed and the maximum dry density and optimum moisture content determined from the plot. The test results are summarized in the 'Maximum Dry ■ HILLTOP GEOTECHNICAL, INC. 665-B07.1 September 19, 2007 Page A-7 Density/Optimum Moisture Content Relationship Test Results,'Plate Nos. 12 and 13, presented in this Appendix. CONSOLIDATION TESTS Hydroconsolidation or the Collapse Potential,Ic, of the on-site soil behavior under load were made on the basis of consolidation tests that were performed on selected relatively undisturbed ring samples of the alluvial soils in general accordance with current ASTM D5333 procedures. The consolidation apparatus is designed to receive a 1-inch high, 2.413-inch diameter ring sample. Porous stones are placed in contact with the top and bottom of each specimen to permit addition and release of pore water. A load of 4,200 pounds per square foot (psf) was applied normal to the face of the specimen at field moisture condition and the sample was allowed to consolidate. Upon completion of the consolidation process,water was added to the test apparatus to create a submerged condition and to measure the collapse (hydroconsolidation) or expansion potential of the sample. The resulting change in sample thickness was recorded. The test results are summarized in the 'Summary of Laboratory Test Results,' Plate No. 11, presented in this Appendix. Settlement predictions of the on-site soil and compacted fill behavior under load were also made based on consolidation tests that were performed in general accordance with current ASTM D2435 procedures. The consolidation apparatus is designed to receive a 1-inch high, 2.413-inch diameter ring sample. Porous stones are placed in contact with the top and bottom of each specimen to permit addition and release of pore water and pore pressure. Loads normal to the face of 7 the specimen are applied in several increments in a geometric progression under both in-situ moisture and submerged conditions. The resulting changes in sample thickness are recorded at selected time intervals. Results are presented on the 'Consolidation Test Results,'Plate Nos. 14 through 16,presented in this Appendix. .Ir HILLTOP GEOTECHNICAL, INC. � o a r� � � � w o e � � � � � � � r � �' � r v m a y f � m nn� o y E r m a m 4 S 9 * � c d� 1 .� i y m r B � � s � � �a � • a H t=f 9 z � Z � � o S s � a � .. � � 0 a z � � b 5' r � �, 665-1307.1 September 19, 2007 Page A-8 DIRECT SHEAR TEST Direct shear tests were performed on selected in-situ and remolded samples of near-surface earth material in general accordance with current ASTM D3080 procedures. The shear machine is of the constant strain type. The shear machine is designed to receive a 1-inch high, 2.413-inch diameter ring sample. Three (3) specimens of the near-surface earth material were remolded at approximately 90 percent relative compaction and at optimum moisture content based on the i maximum dry density and optimum moisture content of the soil as determined by current ASTM D1557 procedures. Specimens from each of the in-situ samples and remolded samples were sheared at various pressures normal to the face of the specimens. The specimens were tested in a submerged condition.

Ontario Street,Suite#200 ERM Burbank, California 91504 Subject: Summary of Findings, Limited Subsurface Investigation San Bernardino Superior Court 247 W. 3rd Street San Bernardino, California Dear Mr. Desai: This letter report presents the results of recent fieldwork performed by ERM-West, Inc. (ERM) at the San Bernardino County Courthouse, located at 247 West 3rd Street in the City of San Bernardino,San Bernardino County, California (Figure 1; hereinafter site). This limited subsurface investigation,which was performed at the request of the Office of Court Construction and Management,Judicial Council of Califomia-Administrative Order of the Courts (AOC) in support of a property transfer,included the collection of soil samples and soil gas samples from four areas at the site. This letter provides a background summary, describes the scope of the work, and presents the sampling results. BACKGROUND In October 2007, Earth Tech conducted a Phase I Environmental Site Assessment (ESA) at the site on behalf of the AOC. The findings of this Phase I ESA were presented in a report entitled Phase I Environmental Site Assessment, Proposed San Bernardino County Courthouse, San Bernardino, California 247 West 3rd Street, San Bernardino, California 92408, (Earth Tech, October 2007). The Phase I ESA determined that historical site operations included automobile repair and paint shops, an auto wrecking facility, and a highway commission garage and repair shop. Mr.Pradip Desai Environmental 25 April 2008 Resources Page 2 Management The approximate locations of structures associated with these operations are depicted on Figure 2. The following underground storage tanks (USTs) were reportedly present in the northeast quadrant of the site and were used for storage of petroleum-related liquids: ' • A 200-gallon waste oil UST; • A 550-gallon diesel UST; ' • A 2,000-gallon unleaded gasoline UST;and • A 4,000-gallon unleaded gasoline UST. Based on the findings of the Phase I ESA,AOC contracted ERM to perform a limited Phase II Investigation to evaluate the potential for impacts due to these historical site operations,including the potential for releases of lead paint and/or asbestos during the demolition of the associated buildings. SCOPE OF WORK A project-specific Health and Safety Plan was prepared prior to implementing the field investigation. Proposed boring locations were marked in the field and Underground Services Alert (USA), a notification service for marking underground utilities,was notified to obtain ' clearance in advance of fieldwork. Drilling was performed by Kehoe Testing and Engineering,a California- ' licensed drilling company, using hand auger and direct-push techniques. The subsurface investigation was limited in depth (maximum boring depth 20 feet below ground surface [bgs]); groundwater was not encountered or sampled. The following subsections describe the field investigation activities and procedures. Soil Gas Sampling On 5 February 2008, ERM advanced four borings for soil gas sampling ' (locations depicted on Figure 2) to evaluate whether elevated concentrations of volatile organic compounds (VOCs) were present in soil gas. The underlying assumption was that if VOCs were present at elevated concentrations in soil gas, this could be an indication that subsurface soils and/or ground water underlying the site were impacted 1 Mr.Pradip Desai Environmental Apr2008 Resources P i1 Page 3 Management ' by historical operations. Ground water is present at a greater depth than those evaluated during this limited subsurface investigation,and as such, ' ground water sampling was beyond the scope of the investigation. Soil gas sampling activities were implemented in accordance with the 15 December 2004 (revised 7 February 2005) Interim Final Guidance for the Evaluation and Mitigation of Subsurface Vapor Intrusion to Indoor Air document developed by the Department of Toxic Substances Control (DTSC) and the California Environmental Protection Agency (Cal/EPA) and the 28 January 2003 Advisory-Active Soil Gas Investigation guidance document developed by the DISC and the Los Angeles Regional Water Quality Control Board (LARWQCB), as summarized below. For subsurface utility clearance purposes, soils at each location were initially augered by hand to 4 feet bgs. After confirming that no utilities appeared to be present in the boring, using the direct-push drilling rig, a vapor sampling rod was advanced to the desired sample depth(6 feet bgs'). Upon attaining this depth,the rod was pulled back to create an annular space for vapor sampling. The probes were set and 1 foot of sand was put on top, then hydrated bentonite chips to the surface. A clear, disposable, polyethylene tubing was then inserted through the rods and attached to the screened sampling tip. The line was allowed to rest for 30 minutes and then 300 milliliters were purged from the line. A 1- liter Summa canister was then attached to the sampling line,and the sample was collected. The final vacuum reading was recorded on the chain-of-custody form for use by the laboratory in determining concentrations. r The four soil gas samples were submitted to Air Toxics Ltd., a California- certified laboratory in Folsom, California,for VOC analysis by U.S. Environmental Protection Agency (USEPA) Method TO-15. After the soil gas sample was collected, the polyethylene tubing was removed and discarded. The borehole was abandoned using bentonite slurry and then covered with an asphalt patch. ' This sampling depth is consistent with that recommended by the DISC/LARWQCB advisory (at least 5 feet bgs). Mr.Pradip Desai Environmental 25 April 2008 Resources Page 4 Management Soil Drilling and Sampling �A After completion of the soil gas sampling, a soil boring was advanced `j immediately adjacent to each soil gas location (i.e.,less than 2 feet away). For subsurface utility clearance purposes, as noted above, the locations for the soil borings were hand augered to 4 feet bgs prior to initiating drilling with the direct-push rig. The soil borings were then advanced using the direct-push rig to the terminus of each boring at 20 feet bgs. Drilling and sampling equipment was decontaminated before sampling was initiated at each boring and upon completion of the investigation. Continuous core samples were collected using 4-foot long by 1.5-inch diameter acetate liners. An ERM field geologist visually observed recovered soil samples and screened the soil cores in the field for the presence of VOCs using a photoionization detector (PID). This was done by cutting the acetate liners and bending them to create a small opening. The PID was then placed in the opening and covered by a gloved hand to keep as much of the gas from escaping as possible. The reading was taken when the numbers on the meter stabilized. Physical observations and PID readings were recorded on boring logs,copies of which are included in Attachment 1. The specific sampling interval within each core was determined based on field observations. The original intent was to select cored intervals that exhibited evidence of impacts. However, no evidence of subsurface impacts (i.e., elevated PID readings,odor, or visual evidence such as discoloration) was observed. Therefore, a single sample was collected for laboratory analysis from each boring at the following depths: Boring ID Sample Collection Depth (feet bgs) B-01 17-18 - B-02 11-12 B-03 13-14 B-04 19-20 A 12-inch length of the acetate tubing (with soil core retained inside), corresponding to the depths noted above (e.g.,from 13 to 14 feet bgs in the case of B-03), was cut and the ends of the liners were covered with Teflon sheets and capped. Soil samples were preserved in the field (i.e., placed into a chilled cooler with ice to maintain a temperature below 6°Celsius [C]) in accordance with USEPA guidance. I Mr.Pradip Desai Environmental 25 April 2008 Resources Pa Management Page 5 Managemm ent All soil samples were submitted to Entech Laboratories (Entech),a California-certified laboratory located in Santa Clara, California,under proper chain-of-custody procedures for laboratory analysis for the following: • Total petroleum hydrocarbons (TPH- extractable and purgeable ranges) by USEPA Method 8015M; • TPH-related VOCs (i.e.,benzene,toluene, ethylbenzene,and xylenes [BTEX] and methyl tert-butyl ether [MTBE]) by USEPA Method 8021; and • Selected metals (standard Leaking Underground Fuel Tank [LUFT] list: cadmium, chromium, lead,nickel, and zinc) by USEPA Method 6010B. After all borings were completed, they were backfilled with granulated bentonite chips and hydrated with water. An asphalt patch was placed on top to match the parking lot. Surface Soil Sampling To assess the potential that asbestos and/or lead-based paint could have ' been released to surface soils during the demolition of the buildings historically present on site, soil samples were also collected from shallow soils in the vicinity of each boring location,as shown on Figure 2. The samples collected on 5 February 2008, were composite samples,which were composed of three sub-samples spaced approximately 3 feet apart, at the approximate locations represented by the triangle symbols on Figure 2. An additional surface soil sample was subsequently collected on 12 April 2008, as discussed later in this report;this sample was a single discrete sample, collected approximately 10 feet north of the former B-1 boring using hand auger sampling methods, from an approximate depth of 2.3 feet bgs. Prior to sampling, the asphalt was removed in paved areas, and any vegetation or general non-native debris was scraped from the soil surface in each sub-sample location. The sub-samples were collected using hand auger techniques, at the apparent depth native soil was encountered (ranging from 2 to 4 feet bgs). A portion of each sub-sample for a given composite sample was placed into a clean, 5-gallon plastic bucket and the contents were mixed together with the other sub-samples for that ID location using a clean, stainless-steel trowel to form the composite sample. Each composite sample was placed in a clean 8-ounce jar Mr.Pradip Desai Environmental 25 April 2008 Resources Page 6 Management provided by the laboratory. Soil samples were preserved in the field (i.e., placed into a chilled cooler with ice to maintain a temperature below 60 C). The composite soil samples were submitted to Entech under proper chain-of-custody procedures for laboratory analysis for the following: • Asbestos (bulk analysis by polarized light microscopy); • Total lead by USEPA Method 6010B; and • Extraction for Soluble Threshold Limit Concentration (STLC) and analysis of the extract by USEPA Method 6010B for lead. After all borings were completed, they were backfilled with granulated bentonite chips and hydrated with water. An asphalt patch was placed on top to match the parking lot. w DATA ANALYSIS AND INTERPRETATION �.� The laboratory analytical report (Attachment 2) was subjected to a quality assurance/quality control (QA/QC) review performed in accordance with U.S. EPA Contract Laboratory Program National Functional Guidelines for Organic Data Review- EPA 540/R-991008 (USEPA, 1999), and U.S. EPA Contract Laboratory Program National Functional Guidelines for Inorganic Data Review- EPA 540/R-04/004 (USEPA,2004). Based on this review, data were determined suitable for decision-making purposes. ERM's QA/QC report is provided in Attachment 2. INVESTIGATION RESULTS Geology and Hydrogeology The four locations (B-01 through B-04) exhibited similar subsurface stratigraphy,which consisted primarily of sands and silty sands. Water was not encountered in any of the boreholes at the depths investigated. Soil Gas Analytical Results ' Four soil gas samples were submitted for laboratory analysis;the resultant laboratory reports and ERM's QA/QC memorandum are provided in Attachment 2, and the results are summarized in Table 1. Mr.Pradip Desai Environmental 25 April 2008 Resources Page 7 Management For ease of presentation, only those constituents detected in at least one sample are shown. As seen in the table and laboratory report, the following VOCs were detected in one or more of the samples: • dichlorodifluoromethane • trichlorofluoromethane ' • carbon disulfide • acetone • 2-butanone • benzene ' • styrene • toluene • tetrachloroethene • p,&m-xylene i • ethylbenzene • 4-ethyl toluene • o-xylene • 1,2,4,-hirnethylbenzene ' • 1,3,5-trimethylbenzene For comparison purposes, the Table 1 includes human health screening levels established by the Cal/EPA for soil gas under residential and commercial/industrial land use scenarios (i.e., California Human Health Screening Levels in Evaluation of Contaminated Properties Uanuary 2005]). These California Human Health Screening Levels (CHHSLs) are not cleanup goals, do not establish policy or regulation,and are not intended to be used as a stand-alone tool for decision making. These screening levels are based on conservative assumptions; detections lower than these screening levels are presumed to pose no risk to human health and the environment and warrant no further attention. As stated in the associated documentation,the presence of a chemical above these criteria does not necessarily indicate that adverse impacts to human health or the environment are occurring. Of the compounds included in the soil gas analyses for which CHHSLs have been established, none of the VOCs were reported at concentrations higher than the industrial or residential CHHSLs. Soil Analytical Results As summarized in the soil drilling and sampling section of this report, eight soil samples (four discrete and four composite) were submitted for ' laboratory analysis as part of the field activities. Copies of the full laboratory reports and ERM's QA/QC memorandum are provided in Attachment 2. The reported detections are summarized below, by compound class. i Mr.Pradip Desai Environmental 25 April 2008 Resources Page 8 Management iMetals (Total) i The analytical results for metals are summarized on Table 2. With the exception of cadmium,which was not detected in any of the four samples,all of the other metals included in the analyses were ' consistently detected in all of the samples. i For comparison purposes,compound-specific, risk-based screening levels (Cal/EPA Preliminary Remediation Goals [PRGs][Region 9 PRGs 2004 Table,USEPA,28 December 2004]) for the residential and commercial/industrial exposure scenarios are provided on Table 2. Detections below these screening levels are generally not considered threats to human health or the environment under the relevant land use. i As seen in Table 2,none of the reported metals concentrations exceeded their respective PRGs for either land use scenario. To evaluate the possibility that the metals detections represent background conditions, ERM compared the Site data to a background data set associated with a nearby property. The background data set, which was provided to ERM by the AOC,was included in a remedial investigation report prepared on behalf of the Southern California Gas Company (SCGC) for their property at 234 North Arrowhead Avenue in San Bernardino;the background sampling locations were within a one- mile radius of the Site. The excerpts from the SCGC report that were provided to ERM for this assessment are duplicated in Attachment 3. 1 The metals data at the Site are comparable to these assumed backgrounddata, as shown in the summary table below: Metal Range of On-Site Detections Range of"Background" (mg/kg) Detections(mg/kg) Chromium 10-25 7.3-19.4 Lead 1.2-84 5-73 Nickel 5.5-22 5-16 Zinc 29-65 33.1-83 As previously noted,the specific purpose of the surface soil samples was to evaluate whether asbestos and lead-based paint (if present in the former structures) could have been released to surface soils during building demolition. The lead concentrations in the surface soil samples were higher than those reported in the deeper samples,but this could i Mr.Pradip Desai Environmental 25 April 2008 Resources Page 9 Management ' reflect natural variability and does not necessarily indicate impacts due to lead-based paint. Soluble Lead ' As previously noted, the surface soil composite samples were extracted and analyzed for soluble lead. As seen in Table 2,there were detections ' of soluble lead in two of the samples,those with the highest total lead concentrations. The comparison standards typically used for soluble metals in site assessments are the STLC thresholds (5.0 milligrams per liter, in the case of lead). STLC exceedances do not indicate that remediation is needed,but if soils excavated from a site exceed these thresholds,they are considered CA-Hazardous, and must be handled and disposed of as such. As seen in Table 2, one of the samples (B-1 comp, collected from the former UST vicinity) exceeded this threshold. This sample is associated with a location on the site outside of the former building footprints, and as such,was considered less likely to contain lead-based paint than the other composite sampling locations. The gasoline USTs in this area were reportedly used for storage of unleaded gasoline;the detection may be associated with the former waste oil UST. The discrete soil sample collected from deeper at the B-1 location was reported as having a relatively low total lead concentration (2.8 milligrams per kilogram [mg/kg]) comparable to those reported for elsewhere on site. Therefore, lead does not appear to have migrated vertically downward in the soil column to any significant degree, as might be the case if there were a large quantity of highly soluble lead- impacted surface soils. However,it should be noted that the presence of surface pavement currently on site could serve to limit the percolation of rainwater as a carrier of this contaminant. To further assess the potential presence of soluble lead in shallow soils,a "step-out" sample was later collected at a location approximately ten feet north of the former B-1 location. As presented in Table 2 and the associated laboratory report, soluble lead concentrations for this soil sample were appreciably lower (0.88 mg/L) and do not exceed the STLC Ithreshold. Mr.Pradip Desai Environmental April 2008 Resources Page 10 Management TPH TPH was detected in only one of the soil samples in which it was analyzed. This detection,which was associated with sample B-4-19-20 collected from the vicinity of the former auto wrecking facility, was in the ' TPH-motor oil range and was relatively low (just above the reporting limit, at 21 mg/kg). Detections at such low concentrations do not ' typically warrant further attention or remediation. VOCs tVOCs were not detected in any of the soil samples in which they were analyzed. Asbestos ' Asbestos was not detected in any of the composite samples collected at the site. CONCLUSIONS ' Based on the lack of physical evidence of subsurface impacts in the soil cores and on the analytical results, assuming that the borings were accurately installed in potential areas of concern, the field investigation results indicate a low likelihood that past historical operations have significantly impacted subsurface conditions or that future Courthouse operations would be adversely affected by such impacts. It should be noted, however,that one soil sample exhibited chemical concentrations that could represent a potential environmental concern at j the property due to the presence of soluble lead. The reported soluble lead concentration in the composite sample collected from the northeast quadrant of the property near the former USTs was anomalously high relative to the other reported detections across the site. This anomalous detection was higher than the STLC threshold,which could trigger hazardous waste handling procedures during development if soils with similar soluble lead concentrations were found to be present on site and were to be disturbed in the future. A soil sample collected subsequently from this area contained an appreciably lower soluble lead concentration, supporting the conclusion that the original detection was anomalous and likely does not represent broad-scale conditions across the site. However, in an abundance of caution, the AOC plans to conduct Mr.Pradip Desai Environmental 12008 Resources Page April 11 11 Management radditional step-out sampling in this immediate area to confirm that the prior elevated soluble lead occurrence is not reflective of actual conditions, as assumed.

Pasadena, California November 2004 Soil gas samples were collected using Summa canisters with a flow regulator to ensure that the canister is filled at the specified flow rate.. To ensure a representative sample, approximately 3 volumes of gas were purged to rid the tubing of atmospheric air and to allow subsurface air to enter. Typically, three times the total volume of the sampling train will be purged from the system.. A representative from the American Environmental Testing Laboratory (AETL) collected the soil gas samples under the supervision of the field geologist. Duplicate samples were collected and analyzed for quality assurance and quality control(QA/QQ- 3.8 GROUNDWATER SAMPLING The three groundwater monitoring wells at the Site (including one at Parcel D) have been dry since August 2002, and therefore, groundwater samples could not be collected during this investigation.. 3.9 BACKGROUND SOIL SAMPLING The objective of collecting background soil samples was to determine the statistical distribution and average level of'selected chemicals in the general vicinity of the Site. Background samples, therefore, were collected from areas not influenced by Site contaminants, or other obvious sources of contamination. During the PEA in March 1994, SAIC collected two background soil samples (BKG-1 and BKG-2) at the depth of 2 feet bgs. In April 1999, background soil sampling was also conducted by Tetra Tech during the site investigation for the San Bernardino II (Rialto) MGP Site (355 Rialto Avenue), Ietra Tech collected background samples in 6 locations (13G-1 through BG-6) at the depth of 1 foot bgs. In three locations (BG-2,BG-4, and BG-6) additional background soil samples were collected, using a hand auger, at the depth of 5 feet bgs The Rialto MGP Site is located approximately 1,100 feet southwest of the Arrowhead MGP Site; therefore, the previous background samples may apply to this RI Report.. The locations of all background soil samples are shown on Figure 3-3. The analytical results of the background samples are included in Appendix C, 3.10 FIELD AIR MONITORING Air monitoring was conducted for volatile organic vapors (VOCs) during the soil boring and sampling operations. VOCs were monitored using a PID meter prior to and during soil boring activities.. The PID readings did not detect the presence of VOCs in the ambient air during the soil boring activities.
