Pollutants of Concern Potential pollutants associated with Urban Runoff from the proposed project must be identified. Exhibit B of the WQMP provides brief descriptions of typical pollutants associated with Urban Runoff and a table that associates typical potential pollutants with types of development(land use). It should be noted that at the Co- Permittees discretion, the Co-Permittees may also accept updated studies from the California Association of Stormwater Quality Agencies (CASQA), USEPA, SWRCB and/or other commonly accepted agencies/associations acceptable to the Co-Permittee for determination of Pollutants of Concern associated with given land use. Additionally, in identifying Pollutants of Concern, the presence of legacy pesticides, nutrients, or hazardous substances in the site's soils as a result of past uses and their potential for exposure to Urban Runoff must be addressed in project-specific WQMPs. The Co-Permittee may also require specific pollutants commonly associated with urban runoff to be addressed based on known problems in the watershed. The list of potential Urban Runoff pollutants identified for the project must be compared with the pollutants identified as causing an impairment of Receiving Waters, if any. To identify pollutants impairing proximate Receiving Waters, each project proponent preparing a project-specific WQMP shall, at a minimum, do the following: 1. For each of the proposed project discharge points, identify the proximate Receiving Water for each discharge point, using hydrologic unit basin numbers as identified in the most recent version of the Water Quality Control Plan for the Santa Ana River Basin or the San Diego Region. 2. Identify each proximate identified above that is listed on the most recent list of Clean Water Act Section 303(d) list of impaired water bodies, which can be found at website www.swrcb.ca.gov/tmdl/303d_lists.html. List all pollutants for which the proximate Receiving Waters are impaired. 3. Compare the list of pollutants for which the proximate Receiving Waters are impaired with the pollutants expected to be generated by the project. Urban Runoff Pollutants: Potential pollutants listed under Exhibit B of the Riverside County WQMP for PaTktng L81 Development include: sediment/turbidity,TDS, nutrients, phosphorous, nitrogen, oxygen demanding substances, bacteria & viruses, and pesticides. Expected pollutants listed under Exhibit B of the Riverside County WQMP for Parking Lot Development include: organic compounds, trash &debris, oil &grease, and metals. The proximate receiving waters are not impaired by any of these pollutants. • 14 W 1114-Tcniuula CA--2821166.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion • Item#1. Addressed in Section II, Receiving Waters table. Item#2. Addressed in Section 1I, Receiving Waters table. Item#3. "Parking Lots" will be used as the pollutant category for this WQMP. As such,the pollutants associated with parking lots are listed below.

As such,these pollutants are the Pollutants of Concern for this project. Legacy Pollutants: No legacy pollutants are present, per the March 5, 2007 Phase I ESA attached in Appendix H. 15 WI114-Tcmwnlo CA--282066.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion IV. Hydrologic Conditions of Concern Impacts to the hydrologic regime resulting from the Project may include increased runoff volume and velocity; reduced infiltration; increased flow frequency, duration, and peaks; faster time to reach peak flow; and water quality degradation. Under certain circumstances, changes could also result in the reduction in the amount of available sediment for transport; storm flows could fill this sediment-carrying capacity by eroding the downstream channel. These changes have the potential to permanently impact downstream channels and habitat integrity. A change to the hydrologic regime of a Project's site would be considered a hydrologic condition of concern if the change would have a significant impact on downstream erosion compared to the pre-development condition or have significant impacts on stream habitat, alone or as part of a cumulative impact from development in the watershed. This project-specific WQMP must address the issue of Hydrologic Conditions of Concern unless one of the following conditions are met: • Condition A: Runoff from the Project is discharged directly to a publicly-owned, operated and maintained MS4; the discharge is in full compliance with Co-Permittee requirements for connections and discharges to the MS4(including both quality and quantity requirements); the discharge would not significantly impact stream habitat in proximate Receiving Waters; and the discharge is authorized by the Co-Permittee. • Condition B: The project disturbs less than 1 acre. The disturbed area calculation should include all disturbances associated with larger plans of development. • Condition C: The project's runoff flow rate, volume, velocity and duration for the post-development condition do not exceed the pre-development condition for the 2-year,24-hour and 10-year 24-hour rainfall events. This condition can be achieved by minimizing impervious area on a site and incorporating other site-design concepts that mimic pre-development conditions. This condition must be substantiated by hydrologic modeling methods acceptable to the Co-Permittee. This P_ s Condition X.

Best Management Practices V.1 SITE DESIGN BMPS Project proponents shall implement Site Design concepts that achieve each of the following: 1) Minimize Urban Runoff 2) Minimize Impervious Footprint 3)Conserve Natural Areas 4) Minimize Directly Connected Impervious Areas (DCIAs) The project proponent should identify the specific BMPs implemented to achieve each Site Design concept and provide a brief explanation for those Site Design concepts considered not applicable. Instructions: Infield below, provide narrative describing which site design concepts were incorporated into project plans. If the project proponent implements a Co-Permittee approved alternative or equally-effective Site Design BMP not specifically described below, the Site Design BMP checkbox in Table 1 should be marked and an additional description indicating,the nature of the BMP and how it addresses the Site Design concept should be provided. Continuewith completion of Table 1. Note: The Co-Permittees general plan or other land use regulations/documents may require several measures that are effectively site design BMPs(such as minimization of directly connected impervious areas and/or setbacks from natural stream courses). The Project Proponent should work with Co-Permittee staff to determine tf those requirements may be interpreted as site design BMPs for use in this table/narrative. See Section 4.5.1 of the WQMP for additional guidance on Site Design BMPs. Following Table 1: if a particular Site Design BMP concept is found to be not applicable,please provide a brief explanation as to why the concept cannot be implemented. Also include descriptions explaining how each included BMP will be implemented. In those areas where Site Design BMPs require ongoing maintenance, the inspection and maintenance frequency, the inspection criteria, and the entity or party responsible for implementation, maintenance, and/or inspection shall be described. The location of each Site Design BMP must also be shown on the WQMP Site Plan included in Appendix B. f fi! � k EY { P- fW I q .. :'- In order to maximize permeable areas an Infiltration Basin and additional Landscaping isproposed m ail MLI_ r pr f rw4 +a .. f .. unpaved areas AnfInfiltrati6ii Basin and Landscaping is p opos edtinahegparkmg lotil ocated to the,east of the expansion Existing landscaping bordenng the Wal Mart parcel along Apis ioadfis not part of the protect and will remain unaltered rPie`seruing exls[ingetrees'and+shrubs along,thevsouth/south east perimeter of the lot `t .. a f V e fd will also maximize the permeable area of the�site The proposedrInfiltration Basm and Landscapingtshall consist'of native and drought tolerant trees and shrubs The natural downstream dramageimto Temecula qi 1F r �n ,w S -� Creekshallfremam'in place Sidewalks and parking lot aisles are designed to the minimum widths necessary and decorate e concrete,is,notlusedrin: he landscaptpg In order to minimize the_mperyiouS footprint; 18 W I I I4-Tciowula CA—292066.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion Table 1.

The location of each Treatment Control BMP must also be shown on the Site Plan included in Appendix B. 2. Complete Table 3: Treatment Control BMP Selection Matrix Directions for completing Table 3: • For each pollutant of concern enter "yes"if identified using Exhibit B(Riverside County WQMP- General Categories of Pollutants of Concern per the instructions specified in Section Ill of this Template), or "no"if not identified for the project. • Check the boxes of selected BMPs that will be implemented for the project to address each pollutant of concern from the project as identified using Exhibit B. Treatment Control BMPs nmst be selected and installed with respect to identified pollutant characteristics and concentrations that will be dischargedfrom the site. • For any identified pollutants of concent not listed in the Treatment Control BMP Selection Matrix, provide an explanation (in space below)of how they will be addressed by Treatment Control BMPs. 3. In addition to completing Table 3, provide detailed descriptions on the location, implementation, installation, and long-term O&M of planned Treatment Control BMPs. For identified pollutants of concern that are causing an impairment in receiving waters, the project WQMP shall incorporate one or more Treatment Control BMPs of medium or high effectiveness in reducing those pollutants. It is the responsibility of the project proponent to demonstrate, and document in the project WQMP, that all pollutants of concern will be fully addressed. The Agency may require information beyond the minimum requirements of this WQMP to demonstrate that adequate pollutant treatment is being accomplished. Supporting engineering calculations forQBMP and/or VBMP, and Treatment Control BMP design details are included in Appendix F. Note: Projects that will utilize infiltration-based Treatment Control BMPs(e.g., Infiltration Basins, Infiltration Trenches, Porous Pavement)must include a copy of the property/project soils report as Appendix E to the project- specific WQMP. The selection of a Treatment Control BMP(or BMPs)for the project must specifically consider the effectiveness of the Treatment Control BMP for pollutants identified as causing all impairment of Receiving Waters to which the project will discharge Urban Runoff. Temecula Creek is listed on the 2006 Clean Water Act Section 303(d) List of Water Quality Limited Segments as being impaired by Phosphorus, Nitrogen, and Total Dissolved Solids. As such, these pollutants are the Pollutants.of Concern for this project For the County of Riverside the 85th Percentile Storm is specified as the storm event to treat. Treatment is to be provided either on a volume basis or a flow basis. For a volume based analysis the County has provided an 85th Percentile Isopluvial Map for the 24-hour storm runoff. For the flow-based analysis the County has accepted an intensity factor(1) of 0.2 inches per hour as the value to be used in the Rational Method equation Q=CIA to determine flow rates in cubic feet per second. We recommend utilizing Contech and Filterra catch 26 W 1114-Tcrticaulu CA--262066.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion basins. This method requires that flow-based structural BMPs have the capacity to treat the maximum flow rate of runoff produced from a rainfall intensity of 0.2 inches per hour of storm event. The system will be installed by the contractor and the owner will be required to regularly maintain these devices. Specific information for both Contech and Filterra catch basins can be found in Appendix F. The Contech catch bas_ui proposed for this project shall utilize filter media that contains perlite, zeolite and granular activated carbon. These three media in combination effectively remove the following: total suspended solids, oil and grease, soluble metals, ammonium, and some organics such as herbicides and pesticides. The Filterra unit ntends,to effectively treat the total suspended solids, phosphorous, nitrogen, heavy metals, fecal coliform as well as oil and grease. r The Pnft ration Basin intends to effectwely treat=the sediment nutrients trash metals M 6actena,,organ�cs as _ wellaas',oil and,'greasej Basin-1• Thts a ea located_ the south west corner of the construct on area is not a part,o£the pr oJe,'ct,As,such;' MPs .: sir 1 ... m ., are.not propose& Basin''2 After the proposed expansion, storm water runoff from the roof area of the expansion will flow to the south and be treated by a 9 cartridge Contech catch basin before connecting to the existing 36" RCP storm drain.

Funding A funding source or sources for the O&M of each Treatment Control BMP identified in the project-specific WQMP must be identified. By certifying the project-specific WQMP, the Project applicant is certifying that the funding responsibilities have been addressed and will be transferred to future owners. One example of how to adhere to the requirement to transfer O&M responsibilities is to record the project-specific WQMP against the title to the property. The groundlessee, Wal-Mart Real Estate Business Trust shall be responsible for the funding of Treatment Control BMP Operation and Maintenance during the term of its lease. FUNDING CERTIFICATION A source of funding is required for all site design, source control, and treatment BMPs. For this project, the groundlessee will fund the installation, and operation and maintenance of all BMPs set forth in this WQMP until the ground lease is terminated. Each groundlessee shall record this WQMP with the County of Riverside as an attachment to the title of the property in order to transfer the O&M responsibilities to each new groundlessee. Where the groundlessee requires a lessee or other party to install, and operate and maintain the BMPs, the groundlessee will maintain ultimate funding responsibilities, and will, upon default of the lessee or other party to fulfill these responsibilities, shall cause the same to be performed at the groundlessee's expense. Nothing in this WQMP shall prevent the groundlessee from pursuing cost recovery from any lessee or other party responsible for the BMPs, or from pursuing remedies for the default of responsibilities as provided by the lease contract and law.

In addition to expanding the store, the project proposes a new 4 bay truck dock, 31 parking stalls, an infiltration basin, landscaping areas, and a Bale and Pallet Recycling Area. The developed property is irregular in shape and encompasses approximately 19.09 acres. The site is located on the southwest comer of Temecula Parkway and Apis Road in the City of Temecula area of the County of Riverside, California (see Vicinity Map). The majority of the site is predominately level with no major changes in grade. Existing drainage from the site flows southwestward into Temecula Creek. A more detailed Hydrology Study was prepared for this proposed project (not included in this Water Quality Technical Report per City of Temecula requirements) to correctly size the proposed curb inlets, storm drain system and BMP's and to verify that the existing storm drain system will still be adequate after the construction of the proposed project. Below is a summary of the above mentioned detailed Hydrology Study. The existing area of the proposed building expansion is unpaved and graded to drain to an existing RSD D-14 graded inlet. The inlet is connected to an existing 18" RCP storm drain and discharge to an existing 36" RCP storm drain. Drainage from the 36" RCP connects to a 42" RCP pipe before it is discharged just southeast of the property to the existing Temecula Creek Channel. No modifications to the main storm drain system are proposed. • The proposed building expansion will be constructed at the unpaved portion of the property. This area was originally graded and designed for this proposed building expansion; therefore, no significant changes in grades will be necessary for storm drain discharge. The original hydrology report approved by the County of Riverside for this project is part of the Plot Plan 16535 which was used as reference for existing conditions data. The original basin at the proposed expansion site will be divided into smaller sub basins for the proposed building expansion and parking.

Pollutants of Concern Potential pollutants associated with Urban Runoff from the proposed project must be identified. Exhibit B of the WQMP provides brief descriptions of typical pollutants associated with Urban Runoff and a table that associates typical potential pollutants with types of development(land use). It should be noted that at the Co- Permittees discretion, the Co-Permittees may also accept updated studies from the California Association of Stormwater Quality Agencies(CASQA), USEPA, SWRCB and/or other commonly accepted agencies/associations acceptable to the Co-Permittee for determination of Pollutants of Concern associated with given land use. Additionally, in identifying Pollutants of Concern,the presence of legacy pesticides, nutrients, or hazardous substances in the site's soils as a result of past uses and their potential for exposure to Urban Runoff must be addressed in project-specific WQMPs. The Co-Permittee may also require specific pollutants commonly associated with urban runoff to be addressed based on known problems in the watershed. The list of potential Urban Runoff pollutants identified for the project must be compared with the pollutants identified as causing an impairment of Receiving Waters, if any. To identify pollutants impairing proximate Receiving Waters, each project proponent preparing a project-specific WQMP shall, at a minimum, do the following: 1. For each of the proposed project discharge points, identify the proximate Receiving Water for each discharge point, using hydrologic unit basin numbers as identified in the most recent version of the Water Quality Control Plan for the Santa Ana River Basin or the San Diego Region. 2. Identify each proximate identified above that is listed on the most recent list of Clean Water Act Section 303(d) list of impaired water bodies,which can be found at website www.swreb.ca.gov/tmdl/303d_lists.html. List all pollutants for which the proximate Receiving Waters are impaired. 3. Compare the list of pollutants for which the proximate Receiving Waters are impaired with the pollutants expected to be generated by the project. Urban Runoff Pollutants. Potential pollutants listed under Exhibit B of the Riverside County WQMP for Parking Lot Development include: sediment/turbidity, TDS, nutrients, phosphorous, nitrogen, oxygen demanding substances,bacteria &viruses, and pesticides. Expected pollutants listed under Exhibit B of the Riverside County WQMP for Parking Lot Development include: organic compounds,trash& debris, oil &grease, and metals. The proximate receiving waters are not impaired by any of these pollutants. is 14 W1114-Temecula CA--282066.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion • Item 91.

Legacy Pollutants: No legacy pollutants are present, per the March 5, 2007 Phase I ESA attached in Appendix H. • 15 W 1114-Temecula CA--282066.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion • IV. Hydrologic Conditions of Concern Impacts to the hydrologic regime resulting from the Project may include increased runoff volume and velocity; reduced infiltration; increased flow frequency, duration, and peaks; faster time to reach peak flow; and water quality degradation. Under certain circumstances, changes could also result in the reduction in the amount of available sediment for transport; storm flows could fill this sediment-carrying capacity by eroding the downstream channel. These changes have the potential to permanently impact downstream channels and habitat integrity. A change to the hydrologic regime of a Project's site would be considered a hydrologic condition of concern if the change would have a significant impact on downstream erosion compared to the pre-development condition or have significant impacts on stream habitat, alone or as part of a cumulative impact from development in the watershed. This project-specific WQMP must address the issue of Hydrologic Conditions of Concern unless one of the following conditions are met: • Condition A: Runoff from the Project is discharged directly to a publicly-owned, operated and maintained MS4; the discharge is in full compliance with Co-Permittee requirements for connections and discharges to the MS4 (including both quality and quantity requirements);the discharge would not significantly impact stream habitat in proximate Receiving Waters; and the discharge is authorized by the Co-Permittee. • • Condition B: The project disturbs less than 1 acre. The disturbed area calculation should include all disturbances associated with larger plans of development. • Condition C: The project's runoff flow rate,volume, velocity and duration for the post-development condition do not exceed the pre-development condition for the 2-year, 24-hour and 10-year 24-hour rainfall events. This condition can be achieved by minimizing impervious area on a site and incorporating other site-design concepts that mimic pre-development conditions. This condition must be substantiated by hydrologic modeling methods acceptable to the Co-Permittee. This Project meets Condition A.

Treatment Control BMPs must be selected and installed with respect to identified pollutant characteristics and concentrations that will be dischargedfrom the site. • For any identified pollutants of concern not listed in the Treatment Control BMP Selection Matrix, provide an explanation(in space below) of how they will be addressed by Treatment Control BMPs. • 3. In addition to completing Table 3,provide detailed descriptions on the location, implementation, installation, and long-term O&M ofplanned Treatment Control BMPs. For identified pollutants of concern that are causing an impairment in receiving waters, the project WQMP shall incorporate one or more Treatment Control BMPs of medium or high effectiveness in reducing those pollutants. It is the responsibility of the project proponent to demonstrate, and document in the project WQMP, that all pollutants of concern will be fully addressed. The Agency may require information beyond the minimum requirements of this WQMP to demonstrate that adequate pollutant treatment is being accomplished. Supporting engineering calculations for QBMP and/or VBMP, and Treatment Control BMP design details are included in Appendix F. Note:Projects that will utilize infiltration-based Treatment Control BMPs (e.g., Infiltration Basins, Infiltration Trenches, Porous Pavement) must include a copy of the property/project soils report as Appendix E to the project- specific WQMP. The selection of a Treatment Control BMP(or BMPs)far the project must specifically consider the effectiveness of the Treatment Control BMP for pollutants identified as causing an impairment of Receiving Waters to which the project will discharge Urban Runoff. Temecula Creek is listed on the 2006 Clean Water Act Section 303(d) List of Water Quality Limited Segments as being impaired by Phosphorus,Nitrogen, and Total Dissolved Solids. As such,these pollutants are the Pollutants of Concern for this project For the County of Riverside the 85th Percentile Storm is specified as the storm event to treat. Treatment is to • be provided either on a volume basis or a flow basis. For a volume based analysis the County has provided an 85th Percentile Isopluvial Map for the 24-hour storm runoff. For the flow-based analysis the County has accepted an intensity factor(I) of 0.2 inches per hour as the value to be used in the Rational Method equation Q=CIA to determine flow rates in cubic feet per second. We recommend utilizing Contech and Filterra catch 26 W1114-Temewle CA--282066.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion • basins. This method requires that flow-based structural BMPs have the capacity to treat the maximum flow rate of runoff produced from a rainfall intensity of 0.2 inches per hour of storm event. The system will be installed by the contractor and the owner will be required to regularly maintain these devices. Specific information for both Contech and Filterra catch basins can be found in Appendix F. The Contech catch basin proposed for this project shall utilize filter media that contains perlite, zeolite and granular activated carbon. These three media in combination effectively remove the following: total suspended solids, oil and grease, soluble metals, ammonium, and some organics such as herbicides and pesticides. The Filterra unit intends to effectively treat the total suspended solids, phosphorous,nitrogen, heavy metals, fecal coliform as well as oil and grease. The Infiltration Basin intends to effectively treat the sediment, nutrients,trash, metals,bacteria, organics as well as oil and grease. Basin 1• This area located at the south-west corner of the construction area is not a part of the project. As such,BMPs are not proposed. Basin 2• • After the proposed expansion, storm water runoff from the roof area of the expansion will flow to the south and be treated by a 9 cartridge Contech catch basin before connecting to the existing 36" RCP storm drain. The design flow rate from Appendix F for this basin is 0.28 cfs, and the flow capacity of the 9 cartridge Contech catch basin equal 0.297 cfs. Basin 3• A single cartridge Contech catch basin will filter runoff in the area of the truck dock and it will be routed to the existing 36" RCP storm drain at the south east end of the site. The design flow rate from Appendix F for this basin is 0.02 cfs, and the flow capacity of the single cartridge Contech catch basin equals 0.033 cfs. Basin 4• This area located at the south-east corner of the construction area is not a part of the project. As such, BMPs are not proposed. Basin 5• Storm water to the east of the proposed truck dock will be routed to a 4'x6.5' Filterra inlet located at the southern most entrance of the site and then routed to the existing 36" RCP pipe. This basin will also utilize porous paving in the parking areas in order to provide shallow percolation. The BMP sizing calculations for the Filterra unit in basin 5 assume that the porous paving is 100% clogged. Basin 5 has a design flow rate from Appendix F of 0.04 cfs while the 4'x6.5' Filterra inlet has a flow capacity o£0.061 cfs. • 27 W1114-Temecula CA--282066.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion • Basin 6• An infiltration basin with a proposed Basin Surface Area of approximately 1,270 square feet is proposed to treat the runoff from the proposed parking area and truck turnaround area. The infiltration basin will include an overflow catch basin which will include a FloGard+Plus Catch Basin Filter Insert Model No. FGP-36F, by Kristar Enterprise Inc. that will treat floatables such as trash and debris. The overflow catch basin will connect to the existing 18" RCP pipe. Basin 6 has a required Basin Surface Area of 706 square feet from Appendix F while the infiltration basin has a Basin Surface Area of 1,270 square feet. All proposed drainage from the 36" storm drain is discharged just south of the property to the existing Temecula Creek Channel.No modifications will be made to the existing 36" storm drain or the Temecula Creek Channel for the proposed building expansion. • • 28 W 1114-Temecula CA--282066.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion • Table 3: Treatment Control BMP Selection Matrix Treatment Control BMP Categories(9) Infiltration Veg.

The preparer of this project-specific WQMP should carefully review Section 4.6 of the WQMP prior to completing this section of the project-specific WQMP. • Self-inspections and record-keeping requirements for BMPs (review local specific requirements . regarding self-inspections and/or annual reporting), including identification of responsible parties for inspection and record-keeping. Instructions: Identify below all operations and maintenance requirements, as described above,for each structural BMP. Where a public agency is identified as the funding source and responsible partyfar a Treatment Control BMP, a copy of the written agreement stating the public agency's acceptance of these responsibilities must be provided in Appendix G. BMPs shall be inspected and maintained prior to and during each rainy season, including conducting an annual inspection no later than September 30th each year. Should any of the project's surface or subsurface drainage/filtration structures or other BMPs fail, the owner shall be responsible for any necessary repairs to the drainage/filtration system or BMPs. Inspect Contech storm filters at least once a year before the winter season. Additional inspections should also be performed after a major storm event. Maintenance includes cartridge replacement and sediment removal. The average maintenance lifecycle is approximately 1-3 years. However, in the event of a chemical spill, the cartridge shall be replaced immediately. The annual O&M Cost listed in the table below is representative of the full maintenance plan offered by Contech and assumes that the cartridges will be replaced every year at a cost of$270 per cartridge plus an additional $360 overall site inspection fee. Filterra units are to be maintained by the supplier or a supplier approved contractor for a minimum period of • 1 year. The cost of this service is included in the price of each Filterra unit. The annual included maintenance consists of a maximum of two (2) scheduled visits; one in the spring and one in the fall. Each scheduled maintenance visit includes 32 W 1114-TCMCa1 CA--282066.1 Water Quality Management Plan (WQMP) Temecula Wal-Mart Expansion 1. Filterra Unit Inspection 2.

The annual O&M costs for the Filterra unit represented below are representative of maintenance performed by the supplier or supplier approved contractor and assume an annual maintenance fee of$125 per unit per year. Regular maintenance is critical to the successful operation of the infiltration basin. Recommended operation and maintenance guidelines include: 1. Schedule semiannual inspection for beginning and end of the wet season to identify potential problems such as erosion of the basin side slopes and invert, standing water,trash and debris, and sediment accumulation. 2. Remove accumulated trash and debris in the basin at the start and end of the wet season. 3. Inspect for standing water at the end of the wet season. 4. Trim vegetation at the beginning and end of the wet season to prevent establishment of woody vegetation and for aesthetic and vector reasons. 5. Remove accumulated sediment and regrade when the accumulated sediment volume exceeds 10% of . the basin. 6. If erosion is occurring within the basin, revegetate immediately and stabilize with an erosion control mulch or mat until vegetation cover is established. 7. To avoid reversing soil development, scarification or other disturbance should only be performed when there are actual signs of clogging, rather than on a routine basis. Always remove deposited sediments before scarification, and use a hand-guided rotary tiller, if possible, or a disc harrow pulled by a very light tractor. The annual O&M cost for the Infiltration Basins represented below are representative of maintenance performed by an Owner hired Representative and assume an annual maintenance fee of$500. FloGard+Plus Catch Basin Insert Filters by Kristar are to be maintained by an Owner hired Representative. This unit shall be inspected prior to, during and following the rainy season.

Funding A funding source or sources for the O&M of each Treatment Control BMP identified in the project-specific WQMP must be identified. By certifying the project-specific WQMP,the Project applicant is certifying that the funding responsibilities have been addressed and will be transferred to future owners. One example of how to adhere to the requirement to transfer O&M responsibilities is to record the project-specific WQMP against the title to the property. The groundlessee, Wal-Mart Real Estate Business Trust shall be responsible for the funding of Treatment Control BMP Operation and Maintenance during the term of its lease. FUNDING CERTIFICATION A source of funding is required for all site design, source control, and treatment BMPs. For this project,the groundlessee will fund the installation, and operation and maintenance of all BMPs set forth in this WQMP until the ground lease is terminated. Each groundlessee shall record this WQMP with the County of Riverside as an attachment to the title of the property in order to transfer the O&M responsibilities to each new groundlessee. Where the groundlessee requires a lessee or other party to install, and operate and maintain the BMPs, the groundlessee will maintain ultimate funding responsibilities, and will, upon default of the lessee or other parry to fulfill these responsibilities, shall cause the same to be performed at the groundlessee's expense. Nothing in this WQMP shall prevent the groundlessee from pursuing cost recovery from any lessee or other party responsible for the BMPs, or from pursuing remedies for the default of responsibilities as provided by the lease contract and law.

The potential for seismic ground rupture is therefore inherently, very low. 4) The historic high groundwater level 'is approximately 16 . feet'below 'existing ground` surface. A seismically-induced liquefaction potential as thus present. 5) The potential for liquefaction-caused 'ground failure is mitigated by construction of a five-foot thick compacted mat below the deepest foundationof a given,structure. For those areas .outsidesa building footprint, appropriate mitigation is accomplished. by construction of a two-foot thick compacted mat' belcw ,proposed subgrades"of, concrete . or .asphaltic surfaces and related infrastructure. 6) The potential for rise in post-construction. groundwater levels is ;very low. 7) Potential "dynamic settlement ranges from about 2.5 to 3 . 0 .inches across building pads : total settlement is about 4. 0 to 6.5 inches. .;The potential dynamic settlement is inherently mitigated to an insignificant level by constructionofthe compacted fill mat. 6) Possible adverse soatic settlement is dependent on .soeci C bll3Sdi rig design and, according!v, is traditionally mitigated to code standards by the project Structural _Engineer. 9) Potential ground =ailure caused by liquefaction-induced lateral spreading is limited to .a "12 feet wide zone parallel to the adjacent Temecula Creek.

In areas of high loading,such as concentrated storage racks,consideration shall be given to Increasing the slab thickness to six Inches. _ • The foundation recommendations presented herein are based on previous laboratory testing and on the anticipated expansion potential and underlying soil conditions. The Structural Engineer shall give consideration to the potential for liquefaction in the design of the foundation system and structure. For design of building and retaining wall footings,an allowable soil bearing capacity of 2,000 pounds per square foot may be used for a 12-Inch-wide continuous footing founded at a minimum depth of 18 Inches below the lowest adjacent final pad grade. This value may be increased by 20 percent for each additional foot of width or depth to a maximum value of 2,500 pounds per square foot. Recommended allowable soil bearing capacities Include both dead and live loads and may be increased by one-third for short-duration wind and seismic forces.

An Increase of one-third of the above values may be used when designing for short-duration wind and seismic forces. Under the above recommended maximum soil bearing capacity, total maximum footing settlements are expected to be less than one inch and differential settlements between adjacent footings are expected to be less than one-half inch over a span of approximately 30 feet. The majority of the anticipated settlements are expected to take place during construction as footing loads are applied. • All footing trenches shall be observed by the project geotechnical consultant to ascertain that they have been excavated into competent bearing soils.

In addition to expanding the store, the project proposes a new 4 bay truck dock, 31 parking stalls, an infiltration basin, landscaping areas, and a Bale and Pallet Recycling Area. The developed property is irregular in shape and encompasses approximately 19.09 acres. The site is located on the southwest corner of Temecula Parkway and Apis Road in the City of Temecula area of the County of Riverside, California(see Vicinity Map). The majority of the site is predominately level with no major changes in grade. Existing drainage from the site flows southwestward into Temecula Creek. A more detailed Hydrology Study was prepared for this proposed project (not included in this Water Quality Technical Report per City of Temecula requirements) to correctly size the proposed curb inlets, storm drain system and BMP's and to verify that the existing storm drain system will still be adequate after the construction of the proposed project. The proposed facilities are designed for Qioo• Below is a summary of the above mentioned detailed Hydrology Study. The existing area of the proposed building expansion is unpaved and graded to drain to an existing RSD D-14 graded inlet. The inlet is connected to an existing 18" RCP storm drain and discharge to an existing 36" RCP storm drain. Drainage from the 36"RCP connects to a 42" RCP pipe before it is discharged just southeast of the property to the existing Temecula Creek Channel. No modifications to the main storm drain system are • proposed. The proposed building expansion will be constructed at the unpaved portion of the property. This area was originally graded and designed for this proposed building expansion; therefore, no significant changes in grades will be necessary for storm drain discharge. The original hydrology report approved by the County of Riverside for this project is part of the Plot Plan 16535 which was used as reference for existing conditions data. The original basin at the proposed expansion site will be divided into smaller sub basins for the proposed building expansion and parking. All proposed storm drain facilities are designed to accommodate the one hundred year storm event. SUMMARY OF RESULTS FOR EXISTING CONDITIONS (City of Temecula Plot Plan 16535) Q2= 17.45 ft3/s** Q10= 22.26 ft3/s Qioo=33.13 ft3/s **Note: Q2 data was not provided on City of Temecula Plot Plan 16535. The Q2 data is an approximate quantity only and is shown for reference only. • September 2, 2008 Page 2 of 6 NE Job No.: 306-035.13 • SUMMARY OF RESULTS FOR PROPOSED CONDITIONS Qz= 19.17 ft3/s Qio=26.16 ft3/s Q1o0=38.80 ft3/s In conclusion,the existing storm drain system in place is still adequate and will be able to handle the insignificant flow increase. This insignificant increase in flow comes from the construction over the existing unpaved area of the building expansion and additional parking. For BMP's sizing and information,please refer to Appendix F of the Water Quality Management Plan. • • September 2, 2008 Page 3 of 6 NE Job No.: 306-035.13 VICINITY MAP 15 LP RoPO P�R10 3/TE T MECULA PARKWAY v N P 9r SITE LOCATION MAP NOT TO SCALE METHODOLOGY The 2-year, 10-year and I00-year storm runoffs were calculated using the Rational Formula Method, per the Riverside County Hydrology Manual. The peak flow rate formula (Q=CIA) was used to calculate the runoffs. • Q = Peak flow rate in cubic feet per second. C = Runoff coefficient expressed as a percentage of rainfall which becomes runoff. September 2, 2008 Page 4 of 6 NE Job No.: 306-035.13 I = Average rainfall intensity in inches per hour for a storm duration equal to the time of concentration of the contributing drainage area. Tc = Time of concentration—Assumed 5 minute minimum. A= Area of basin in acres. CALCULATIONS Site Characteristics and Assumptions: • Hydrologic Soil Group B — See Geotechnical Report in the Water Quality Management Plan. • Percent Impervious = Approximately 90% • See Attached Hydrology Maps for Basin Location and properties. • Assume T, = 5.00 minutes minimum if T,is less than 5.00 minutes.

Rimm Drain Inserts NIP-52 • Design Considerations Description Drain inserts are manufactured filters or fabric placed in a drop ■ Use with other BMPs inlet to remove sediment and debris. There are a multitude of ■ Fit and Seal Capacity within Inlet inserts of various shapes and configurations, typically falling into one of three different groups: socks, boxes, and trays. The sock consists of a fabric, usually constructed of polypropylene. The fabric may be attached to a frame or the grate of the inlet holds the sock. Socks are meant for vertical (drop) inlets. Boxes are constructed of plastic or wire mesh. Typically a polypropylene "bag" is placed in the wire mesh box. The bag takes the form of the box. Most box products are one box; that is, the setting area and filtration through media occur in the same box. Some products consist of one or more trays or mesh grates. The trays may hold different types of media. Filtration media vary by manufacturer. Types include polypropylene, porous polymer, treated cellulose, and activated carbon. California Experience Targeted Constituents The number of installations is unknown but likely exceeds a ✓ Sediment thousand. Some users have reported that these systems require ✓ Nutrients considerable maintenance to prevent plugging and bypass. ✓ Trash ✓ Metals Advantages Bacteria • ■ Does not require additional space as inserts as the drain / Oil and Grease inlets are already a component of the standard drainage / Organics systems. Removal Effectiveness ■ Easy access for inspection and maintenance. See New Development and Redevelopment Handbook-Section 5. ■ As there is no standing water,there is little concern for mosquito breeding. ■ A relatively inexpensive retrofit option. Limitations Performance is likely significantly less than treatment systems that are located at the end of the drainage system such as ponds and vaults. Usually not suitable for large areas or areas with trash or leaves than can plug the insert. Design and Sizing Guidelines Refer to manufacturer's guidelines. Drain inserts come any many configurations but can be placed into three general groups: socks,boxes, and trays. The sock consists of a fabric, usually constructed of polypropylene. The fabric may be attached to a frame or the grate of the inlet holds the sock. Socks are meant S0 A • for vertical (drop) inlets. Boxes are constructed of plastic or wire 'kCa2_ovna mesh.

One manufacturer has a double-box. Stormwater enters the first box where setting occurs. stormwater flows into the second box where the filter media is located. Some products consist of one or more trays or mesh grates. The trays can hold different types of media. Filtration media vary with the manufacturer: types include polypropylene, porous polymer, treated cellulose, and activated carbon. Construction/Inspection Considerations Be certain that installation is done in a manner that makes certain that the stormwater enters the unit and does not leak around the perimeter. Leakage between the frame of the insert and the frame of the drain inlet can easily occur with vertical (drop) inlets. Performance Few products have performance data collected under field conditions. Siting Criteria It is recommended that inserts be used only for retrofit situations or as pretreatment where other treatment BMPs presented in this section area used. Additional Design Guidelines Follow guidelines provided by individual manufacturers. Maintenance •Likely require frequent maintenance, on the order of several times per year. Cost e The initial cost of individual inserts ranges from less than $ioo to about $2,000. The cost of using multiple units in curb inlet drains varies with the size of the inlet. ® The low cost of inserts may tend to favor the use of these systems over other, more effective treatment BMPs. However, the low cost of each unit may be offset by the number of units that are required, more frequent maintenance, and the shorter structural life (and therefore replacement).

Several drip pans should be stored in a covered location near the liquid transfer area so that they are always • available,yet protected from precipitation when not in use. Drip pans can be made specifically for railroad tracks. Drip pans must be cleaned periodically, and drip collected materials must be disposed of properly. ■ Pave loading areas with concrete instead of asphalt. ■ Avoid placing storm drains in the area. ■ Grade and/or berm the loading/unloading area to a drain that is connected to a deadend. Inspection ■ Check loading and unloading equipment regularly for leaks, including valves, pumps,flanges and connections. ■ Look for dust or fumes during loading or unloading operations. Training • Train employees (e.g., fork lift operators) and contractors on proper spill containment and cleanup. s Have employees trained in spill containment and cleanup present during loading/unloading. • Train employees in proper handling techniques during liquid transfers to avoid spills. ■ Make sure forklift operators are properly trained on loading and unloading procedures. • 2 of 4 California Stormwater BMP Handbook January 2003 Industrial and Commercial www.cabmphandbooks.com • Outdoor Loading/Unloading SC-30 Spill Response and Prevention ■ Keep your Spill Prevention Control and Countermeasure (SPCC) Plan up-to-date. ■ Contain leaks during transfer. ■ Store and maintain appropriate spill cleanup materials in a location that is readily accessible and known to all and ensure that employees are familiar with the site's spill control plan and proper spill cleanup procedures. ■ Have an emergency spill cleanup plan readily available. ■ Use drip pans or comparable devices when transferring oils, solvents, and paints. Other Considerations (Limitations and Regulations) ■ Space and time limitations may preclude all transfers from being performed indoors or under cover. ■ It may not be possible to conduct transfers only during dry weather. Requirements Costs Costs should be low except when covering a large loading/unloading area. • Maintenance ■ Conduct regular inspections and make repairs as necessary. The frequency of repairs will depend on the age of the facility. ■ Check loading and unloading equipment regularly for leaks. ■ Conduct regular broom dry-sweeping of area. Supplemental Information Further Detail of the BMP Special Circumstances for Indoor Loading/Unloading of Materials Loading or unloading of liquids should occur in the manufacturing building so that any spills that are not completely retained can be discharged to the sanitary sewer,treatment plant, or treated in a manner consistent with local sewer authorities and permit requirements. 9 For loading and unloading tank-trucks tc above and below ground storage tanks. the following procedures should be used: - The area where the transfer takes place should be paved. If the liquid is reactive with the asphalt, Portland cement should be used to pave the area. - The transfer area should be designed to prevent run-on of stormwater from adjacent areas. Sloping the pad and using a curb,like a speed bump, around the uphill side of the transfer area should reduce run-on. January 2003 California Stormwater BMP Handbook 3 of 4 Industrial and Commercial SC-30 Outdoor Loading/ Unloading. The transfer area should be designed to prevent runoff of spilled liquids from the area. Sloping the area to a drain should prevent runoff. The drain should be connected to a dead-end sump or to the sanitary sewer. A positive control valve should be installed on the drain. ■ For transfer from rail cars to storage tanks that must occur outside,use the following procedures: - Drip pans should be placed at locations where spillage may occur,such as hose connections,hose reels, and filler nozzles. Use drip pans when making and breaking connections. - Drip pan systems should be installed between the rails to collect spillage from tank cars.

Waste Reduction and Recgcling ■ Recycle wastes whenever possible. Many types of waste can be recycled, recycling options for each waste type are limited. All gasoline,antifreeze,waste oil, and lead-acid batteries can be recycled. Latex and oil-based paint can be reused, as well as recycled. Materials that cannot be reused or recycled should either be incinerated or disposed of at a properly permitted landfill. w ■ Recycling is always preferable to disposal of unwanted materials. ■ Recycling bins for glass, metal, newspaper,plastic bottles and other recyclable household solid wastes should be provided at public facilities and/or for residential curbside collection. Controlling Litter ■ Post"No Littering" signs and enforce anti-litter laws. ■ Provide litter receptacles in busy,high pedestrian traffic areas of the community, at recreational facilities, and at community events. ■ Clean out and cover litter receptacles frequently to prevent spillage. Illegal Dumping Substances illegally dumped on streets and into the stone drain system and creels include paints, used oil and other automotive fluids,construction dcbriS, chemicals,fresh concrete, leaves,grass elipning, and pet wastes. • Post"No Dumping' signs w th a prone number for reporting dumping and disposal.

Costs for structural controls such as trash racks,bar screens, and silt traps can be quite costly ranging from$250,000 to $900,000. ■ A collection facility or curbside collection for used oil may result in significant costs. Commercial locations(automobile service stations,quick oil change centers,etc.)as collection points elhninate hauling and recycling costs. ■ Collection and disposal of hazardous waste can be very expensive and requires trained operators;laboratory and detection equipment; and extensive record keeping including dates,types,and quantities. ■ Use of volunteer work forces can lower storm drain stenciling program costs. Stenciling lits require procurement of durable/disposable items_ The stenciling program can aid in the cataloging of the storm drain system. One municipality from the state of Washington has estimated that stenciling kits cost approximately$5o each. Stencils may cost about $8 each including the die cost on an order of t,000. Re-orders cost about $i/stencil. Stencil designs may be available from other communities. Stencil kits should be provided on a loan basis to volunteer groups free of charge with the understanding that kit remnants are to be returned. • Maintenance ■ The primary staff demand for stenciling programs is for program setup to provide marketing and training. Ongoing/follow-up staff time is minimal because of volunteer services. ■ Staffing requirements are minimal for oil recycling programs if collection/recycling is contracted out to a used oil hauler/re veler or required at commercial locations. ■ Staff requirements for maintaining good housekeeping BMPs at waste handling sites is minimal.

Suggested Protocols Catch Basins/Inlet Structures ■ Staff should regularly inspect facilities to ensure compliance with the following: - immediate repair of any deterioration threatening structuralintegrity. - Cleaning before the sump is 40561 full. Catch basins should be cleaned as frequently as needed to meet this standard. - Stenciling of catch basins and inlets (see SC34 WasteY >t jx;California Handling and Disposal). stormwafer , Quality h '_ - ssociation ]anuary 2003 California Stormwater BMP Handbook 1 of 6 Industrial and Commercial www.cabmphandbooks.com • SC-44 Drainage System Maintenance ■ Clean catch basins, storm drain inlets,and other conveyance structures before the wet season to remove sediments and debris accumulated during the summer. ■ Conduct inspections more frequently during the wet season for problem areas where sediment or trash accumulates more often. Clean and repair as needed. ■ Keep accurate logs of the number of catch basins cleaned. ■ Store wastes collected from cleaning activities of the drainage system in appropriate containers or temporary storage sites in a manner that prevents discharge to the storm drain. ■ Dewater the wastes if necessary with outflow into the sanitary sewer if permitted. Water should be treated with an appropriate filtering device prior to discharge to the sanitary sewer. If discharge to the sanitary sewer is not allowed,water should be pumped or vacuumed to a tank and properly disposed. Do not dewater near a storm drain or stream. Storm Drain Conveyance System ■ Locate reaches of storm drain with deposit problem's and develop a flushing schedule that keeps the pipe clear of excessive buildup. ■ Collect and pump flushed effluent to the sanitary sewer for treatment whenever possible. • Pump Stations 111 Clean all storm drain pump stations prior to the wet season to remove silt and trash. ■ Do not allow discharge to reach the storm drain system when cleaning a storm drain pump station or other facility. ■ Conduct routine maintenance at each pump station. ■ Inspect, clean, and repair as necessary all outlet structures prior to the wet season. Open Channel ■ Modify storm channel characteristics to improve channel hydraulics, increase pollutant removals, and enhance channel/creek aesthetic and habitat value. ■ Conduct channel modification/improvement in accordance with existing laws. Any person, government agency, or public utility proposing an activity that will change the natural (emphasis added) state of any river, stream, or lake in California,must enter into a Steam or Lake Alteration Agreement with the Department of Fish and Game. The developer-applicant should also contact local governments (city, county, special districts), other state agencies (SWRCB, RWQCB, Department of Forestry, Department of Water Resources), and Federal Corns of Engineers and USFWS. Illicit Connections and Discharges a Look for evidence of illegal discharges or illicit connections during routine maintenance of convevance system and drainage structures: . - Is there evidence of spills such as paints, discoloring, etc? 2 of 6 California Stormwater BMP Handbook January 2003 Industrial and Commercial www.cabmphandbooks.com • Drainage System Maintenance SC-44 - Are there any odors associated with the drainage system? - Record locations of apparent illegal discharges/illicit connections? - Track flows back to potential dischargers and conduct aboveground inspections. This can be done through visual inspection of upgradient manholes or alternate techniques including zinc chloride smoke testing, fluorometric dye testing,physical inspection testing, or television camera inspection. - Eliminate the discharge once the origin of flow is established. ■ Stencil or demarcate storm drains,where applicable,to prevent illegal disposal of pollutants. Storm drain inlets should have messages such as"Dump No Waste Drains to Stream" stenciled next to them to warn against ignorant or intentional dumping of pollutants into the storm drainage system. ■ Refer to fact sheet SC-10 Non-Stormwater Discharges. Illegal Dumping ■ Inspect and clean up hot spots and other storm drainage areas regularly where illegal dumping and disposal occurs. ■ Establish a system for tracking incidents. The system should be designed to identify the • following: - Illegal dumping hot spots - Types and quantities(in some cases) of wastes - Patterns in time of occurrence(time of day/night,month, or year) - Mode of dumping (abandoned containers,"midnight dumping"from moving vehicles, direct dumping of materials, accidents/spills) - Responsible parties ■ Post"No Dumping" signs in problem areas with a phone number for reporting dumping and disposal. Signs should also indicate fines and penalties for illegal dumping. ■ Refer to fact sheet SC-10 Non-Stormwater Discharges. Training E Train crews in proper maintenance activities, including record keeping and disposal. • Allow only properly trained individuals to handle hazardous materials/wastes. e Have staff involved in detection and removal of illicit connections trained in the following: OSHA-required Health and Safety Training (29 CFR 19io.i2o)plus annual refresher • training (as needed). 3anuary 2003 California Stormwater BMP Handbook 3 of 6 Industrial and Commercial www.cabmphandbooks.com SC-44 Drainage System Maintenance - OSHA Confined Space Entry training(Cal-OSHA Confined Space,Title 8 and Federal OSHA 29 CFR 1910.146). - Procedural training (field screening, sampling, smoke/dye testing, TV inspection). Spill Response and Prevention ■ Investigate all reports of spills,leaks, and/or illegal dumping promptly. ■ Clean up all spills and leaks using"dry" methods (with absorbent materials and/or rags) or dig up, remove, and properly dispose of contaminated soil. ■ Refer to fact sheet SC-ii Spill Prevention, Control, and Cleanup. Other Considerations(Limitations and Regulations) ■ Clean-up activities may create a slight disturbance for local aquatic species. Access to items and material on private property may be limited. Trade-offs may exist between channel hydraulics and water quality/riparian habitat. If storm channels or basins are recognized as wetlands, many activities, including maintenance, may be subject to regulation and permitting. ■ Storm drain flushing is most effective in small diameter pipes (36-inch diameter pipe or less, depending on water supply and sediment collection capacity). Other considerations associated with storm drain flushing may include the availability of a water source, finding a • downstream area to collect sediments,liquid/sediment disposal, and prohibition against disposal of flushed effluent to sanitary sewer in some areas. ■ Regulations may include adoption of substantial penalties for illegal dumping and disposal. ■ Local municipal codes may include sections prohibiting discharge of soil, debris, refuse, hazardous wastes, and other pollutants into the storm drain system. Requirements Costs ■ An aggressive catch basin cleaning program could require a significant capital and O&M budget. ■ The elimination of illegal dumping is dependent on the availability, convenience, and cost of alternative means of disposal. The primary cost is for staff time. Cost depends on how aggressively a program is implemented. Other cost considerations for an illegal dumping program include: - Purchase and installation of signs. - Rental of vehicle(s)to haul illegally-disposed items and material to landfills. - Rental of heavy equipment to remove larger items (e.g., car bodies) from channels. - Purchase of landfill space to dispose of illegally-dumped items and material. • 4 of 6 California Stormwater BMP Handbook January 2003 Industrial and Commercial www.cabmphandbooks.com • Drainage System Maintenance SC-44 ■ Methods used for illicit connection detection (smoke testing, dye testing,visual inspection, and flow monitoring) can be costly and time-consuming. Site-specific factors, such as the level of impervious area, the density and ages of buildings, and type of land use will determine the level of investigation necessary. Maintenance ■ Two-person teams may be required to clean catch basins with vactor trucks. ■ Teams of at least two people plus administrative personnel are required to identify illicit discharges, depending on the complexity of the storm sewer system. ■ Arrangements must be made for proper disposal of collected wastes. ■ Technical staff are required to detect and investigate illegal dumping violations. Supplemental Information Further Detail of the BMP Storm Drain Flushing Flushing is a common maintenance activity used to improve pipe hydraulics and to remove pollutants in storm drainage systems. Flushing may be designed to hydraulically convey accumulated material to strategic locations, such as an open channel, another point where flushing will be initiated, or the sanitary sewer and the treatment facilities,thus preventing • resuspension and overflow of a portion of the solids during storm events. Flushing prevents "plug flow" discharges of concentrated pollutant loadings and sediments. Deposits can hinder the designed conveyance capacity of the storm drain system and potentially cause backwater conditions in severe cases of clogging. Storm drain flushing usually takes place along segments of pipe with grades that are too flat to maintain adequate velocity to keep particles in suspension. An upstream manhole is selected to place an inflatable device that temporarily plugs the pipe. Further upstream,water is pumped into the line to create a flushing wave. When the upstream reach of pipe is sufficiently full to cause a flushing wave,the inflated device is rapidly deflated with the assistance of a vacuum pump,thereby releasing the backed up water and resulting in the cleaning of the storm drain segment. To further reduce impacts of stormwater pollution, a second inflatable device placed well downstream may be used to recollect the water after the force of the flushing wave has dissipated. A pump may then be used to transfer the water and accumulated material to the sanitary sewer for treatment. In some cases, an interceptor structure may be more practical or required to recollect the flushed waters. It has been found that cleansing efficiency of periodic flush waves is dependent upon flush volume,flush discharge rate, sewer slope, sewer length, sewer flow rate,sewer diameter, and population density. As a rule of thumb,the length of line to be flushed should not exceed foo feet. At this maximum recommended length,the percent removal efficiency, ranges between 65- 75%for organics and 55-65%for dry weather grit/inorganic material. The percent removal efficiency drops rapidly beyond that. Water is commonly supplied by a water truck,but fire hydrants can also supply water. To make the best use of water, it is recommended that reclaimed water be used or that fire hydrant line flushing coincide with storm sewer flushing.

Integrating and incorporating appropriate landscape planning methodologies into the project design is the most effective action that can be done to minimize surface and groundwater contamination from stormwater. Approach Landscape planning should couple consideration of land smtabihty for urban uses with consideration of community goals and projected growth. Project plan designs should conserve natural areas to the extent possible, maximize natural water storage and infiltration opportunities,and protect slopes and channels. Suitable Applications Appropriate auplications include residential,commercial and industrial areas planned for development or redevelopment. Design Considerations Design requirements for site design and landscapes planning should conform to applicable standards and specifications of agencies with jurisdiction and be consistent with applicable General Plan and Local Area Plan policies- January olicies. c r JanuaryL00:; California 5tormwater BMP Handbook 1 of 4 Neve Development and Redevelooment www.cabmpha ndbooks.com • SD-10 Site Design & Landscape Planning Designing New Installations Begin the development of a plan for the landscape unit with attention to the following general principles: ■ Formulate the plan on the basis of clearly articulated community goals. Carefully identify conflicts and choices between retaining and protecting desired resources and community grow=th. ■ Map and assess land suitability-for urban uses. Include the following landscape features in the assessment: wooded land,open unwooded land,steep slopes, erosion-prone soils, foundation suitability, soil suitability for waste disposal,aquifers,aquifer recharge areas, wetlands,floodplams,surface waters,agricultural lands,and various categories of urban land use. When appropriate,the assessment can highlight outstanding local or regional resources that the community determines should be protected(e.g., a scenic area,' recreational area, threatened species habitat,farmland,fish ran). Mapping and assessment should recognize not only these resources but also additional areas needed for their sustenance. Project plan designs should conserve natural areas to the extent possible,maximize natural water storage and infiltration opportunities, and protect slopes and channels. Conserve Natural Areas daring Landscape Planning • If applicable,the following items are required and must be implemented in the site layout during the subdivision design and approval process, consistent with applicable General Plan and Local Area Plan policies: ■ Cluster development on least-sensitive portions of a site while leaving the remaining land in a natural undisturbed condition_ ■ Limit clearing and grading of native vegetation at a site to the minimum amount needed to build lots, allow*access, and provide fire protection. ■ Maximize trees and other vegetation at each site by planting additional vegetation,clustering tree areas, and promoting the use of native and/or drought tolerant plants. ■ Promote natural vegetation by using parking lot islands and other landscaped areas. ■ Preserve riparian areas and wetlands. Itladmize Natural Water Storage ana Injtitrarion Opportlmiries Within the Landscape Jnf£ ■ promote the conservation of forest cover. Building on land that is already deforested affects basin hvdroloa-to a lesser extent than converting forested land. Loss of forest cover reduces intervention storage, detention in the organic forest floor iaver, and water losses av evapotranspiration, resulting in large peak runoff increases and either their negative effects or the expense-of countering them with structural solutions. ■ Maintain natmll storage reservoirs and drainage corridors, including depressions; areas of permeable soils, swales, and intermittent streams. Develop and implement policies and • of 4 Caliiomia Stormwarer BMP Handbook Januar,= 2003 New Development and Redevelopment www.cabmpband books.con) Site Design & Landscape Planning SD-10 • regulations to discourage the clearing,filling, and channelization of these features. Utilize them in drainage networks in preference to pipes,culverts,and engineered ditches. ■ Evaluating infiltration opportunities by referring to the stormwater management manual for the jurisdiction and pay particular attention to the selection criteria for avoiding groundwater contamination,poor soils, and hydrogeological conditions that cause these facilities to fail. If necessary,locate developments with large amounts of impervious surfaces or a potential to produce relatively contaminated runoff away from groundwater recharge areas. Protection of Slopes and Channels during Landscape Design ■ Convey runoff safely from the tops of slopes_ ■ Avoid disturbing steep or unstable slopes. ■ Avoid disturbing natural channels. ■ Stabilize disturbed slopes as quicldy as possible. ■ Vegetate slopes with native or drought tolerant vegetation. ■ Control and treat flows in landscaping and/or other controls prior to reaching existing natural drainage systems. • ■ Stabilize temporary and permanent channel crossings as quicldy as possible,and ensure that increases in run-off velocity and frequency caused by the project do not erode the channel. ■ Install energy dissipaters,such as riprap,at the outlets of new storm drains,culverts, conduits,or channels that enter unlined channels in accordance with applicable specifications to minimize erosion. Energy dissipaters shall be installed in such a way as to minimize impacts to receiving waters. ■ Line on-site conveyance channels where appropriate,to reduce erosion caused by increased flow velocity due to increases in tributary impervious area. The first choice for linings should be grass or some other vegetative surface, since these materials not only reduce runoff velocities,but also provide water quality benefits from filtration and infiltration. If velocities in the channel are high enough to erode grass or other vegetative linings,riprap, concrete, soil cement,or geo-grid stabilization are other alternatives. • Consider other'desien m9nClnleS that are conmarable and equally effective.

Choose plants with low irrigation requirements(for example, native or drought tolerant species). Consider design features such as: - Using mulches(such as wood chips or bar)in planter areas without ground cover to minimize sediment in runoff - Installing appropriate plant materials for the location,in accordance with amount of sunlight and climate, and use native plant materials where possible and/or as recommended by the landscape architect - Leaving a vegetative barrier along the property boundary and interior watercourses, to act as a pollutant filter, where appropriate and feasible - Choosing plants that minimize or eliminate the use of fertilizer or pesticides to sustain growth ■ Employ other comparable, equally effective methods to reduce irrigation water runoff.

Posting notices regarding discharge prohibitions at storm drain inlets can prevent waste dumping. Storm drain signs and stencils are highly visible source controls that are typically placed directly adjacent to storm drain inlets. Approach . The stencil or affixed sign contains a brief statement that prohibits dumping of improper materials into the urban runoff conveyance system. Storm drain messages have become a popular method of alerting the public about the effects of and the prohibitions against waste disposal. Suitable Applications Stencils and signs alert the public to the destination of pollutants discharged to the storm drain. Signs are appropriate in residential, commercial, and industrial areas, as well as any other area where contributions or dumping to storm drains is likely. Design Considerations Storm drain message markers or placards are recommended at all storm drain inlets within the boundary of a development project. The marker should be placed in clear sight facing toward anyone approaching the inlet from either side. All storm drain inlet locations should be identified on the development site map. Resigning New Installations The following methods should be considered for inclusion in the project design and show on project plans: e Provide stenciling or labeling of all storm drain inlets and k catch basins. constructed or modified within the prcj ect area with prohibitive language. Examples include"NO DUMPING L � January 2003 California Stormwater BIAP Haridboolr 1 of-, Nev.,Development and P.edevelopment il SD- 13 Storm Drain Signage -DRAINS TO OCEAN" and,/or other graphical icons to discourage illegal dumping. ■ Post signs with prohibitive language and/or graphical icons, which prohibit illegal dumping at public access points along channels and creeks within the project area. Note- Some local agencies have approved specific signage and/or storm drain message placards for use. Consult local agency stormwater staff to determine specific requirements for placard types and methods of application. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans(SUSMP, WQMP, etc.) define"redevelopment" in terms of amounts of additional impervious area,increases in gross floor area and/or exterior construction, and land disturbing activities with structural or impervious surfaces. If the project meets the definition of"redevelopment',then the requirements stated under" designing new installations" above should be included in all project design plans. Additional Information Maintenance Considerations ■ Legibility of markers and signs should be maintained. If required by the agency with jurisdiction over the prof ect, the owner/operator or homeowner's association should enter into a maintenance agreement with the agency or record a deed restriction upon the property title to maintain the legibility of placards or signs. • Placement ■ Signage on top of curbs tends to weather and fade. ■ Signage on face of curbs tends to be worn by contact with vehicle tires and sweeper brooms.

Materials may be in the form of raw products, by-products, finished products, and waste products. The type of pollutants associated with the materials will • vary depending on the type of commercial or industrial activity. Approach Outdoor storage areas require a drainage approach different from the typical infiltration/detention strategy. In outdoor storage areas, infiltration is discouraged. Containment is encouraged. Preventative measures include enclosures, secondary containment structures and impervious surfaces. Suitable Applications Appropriate applications include residential, commercial and industrial areas planned for development or redevelopment. Design Considerations Some materials are more of a concern than others. Toxic and hazardous materials must be prevented from coming in contact with stormwater. Non-toxic or non-hazardous materials do not have to be prevented from stormwater contact. However, these materials may have toxic effects on receiving waters if allowed to be discharged with stormwater in significant quantities. Accumulated material on an impervious surface could result in significant impact on the rivers or streams that receive the runoff. Material may be stored in a variety of ways, including bulk piles, containers, shelving, stacking, and tanks. Stormwater r contamination may be prevented by eliminating the possibility of \ AS Q',A stormwater contact with the material storage areas either through California diversion, cover, or capture of the stormwater.

Control measures are site specific, and must meet local agency requirements. Designing New Installations Where proposed project plans include outdoor areas for storage of materials that may contribute pollutants to the stormwater conveyance system, the following structural or treatment BMPS should be considered: e Materials with the potential to contaminate stormwater should be: (1) placed in an enclosure such as, but not limited to, a cabinet, shed, or similar structure that prevents contact with runoff or spillage to the stormwater conveyance system, or (2) protected by secondary containment structures such as berms, dikes, or curbs. ® The storage area should be paved and sufficiently impervious to contain leaks and spills. e The storage area should slope towards a dead-end sump to contain spills and direct runoff from downspouts/roofs should be directed away from storage areas. c The storage area should have a roof or awning that extends beyond the storage area to minimize collection of stormwater within the secondary,containment area. A manufactured storage shed maybe used for small containers. • Note that the location(s) of installations of where these preventative measures will be employed must be included on the map or plans identifying BMPs. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) define "redevelopment' in terns of amounts of additional impervious area, increases in gross floor area and/or exterior construction, and land disturbing activities with structural or impervious surfaces. The definition of" redevelopment' must be consulted to determine whether or not the requirements for new development apply to areas intended for redevelopment. If the definition applies, the steps outlined under "designing new installations" above should be followed. Additional Information Stormwater and non-stormwater will accumulate in containment areas and sumps with impervious surfaces. Contaminated accumulated water must be disposed of in accordance with applicable laws and cannot be discharged directly to the storm drain or sanitary sewer system without the appropriate permits.

Expect rental rates from $58/hour (3 yd3 hopper)to $88/hour (9 yd3 hopper), plus operator costs. Hourly production rates vary with the amount of area to be swept and amount of sediment. Match the hopper size to the area and expect sediment load to minimize time spent dumping. Inspection and Maintenance ■ Inspect BMPs prior to forecast rain, daily during extended rain events, after rain events, weekly during the rainy season, and at two-week intervals during the non-rainy season. ■ When actively in use, points of ingress and egress must be inspected daily. ■ When tracked or spilled sediment is observed outside the construction limits,it must be removed at least daily. More frequent removal, even continuous removal, may be required in some jurisdictions. • ■ Be careful not to sweep up any unknown substance or any object that may be potentially hazardous. ■ Adjust brooms frequently; maximize efficiency of sweeping operations. ■ After sweeping is finished, properly dispose of sweeper wastes at an approved dumpsite.

California Experience Infiltration basins have a long history of use in California, especially in the Central Valley. Basins located in Fresno were among those initially evaluated in the National Urban Runoff Program and were found to be effective at reducing the volume of runoff,while posing little long-term threat to groundwater quality(EPA, 1983; Schroeder, 1995)• Proper siting of these devices is crucial as underscored by the experience of Caltrans in siting two basins in Southern California. The basin with marginal separation from groundwater and soil permeability failed immediately and could never be rehabilitated.

Limitations ■ May not be appropriate for industrial sites or locations where spills may occur. o Infiltration basins require a minimum soil infiltration rate of 0.5 inches/hour, not appropriate at sites with Hydrologic Soil Types C and D. o If infiltration rates exceed 2.4 inches/hour, then the runoff should be fully treated prior to infiltration to protect groundwater quality. o Not suitable on fill sites or steep slopes. ■ Risk of groundwater contamination in very coarse soils. ■ Upstream drainage area must be completely stabilized before construction. ■ Difficult to restore functioning of infiltration basins once clogged. • Design and Sizing Guidelines o Water quality volume determined by local requirements or sized so that 85% of the annual runoff volume is captured. ® Basin sized so that the entire water quality volume is infiltrated within 48 hours. o Vegetation establishment on the basin floor may help reduce the clogging rate. Construction/Inspection Considerations e Before construction begins, stabilize the entire area draining to the facility. If impossible, place a diversion berm around the perimeter of the infiltration site to prevent sediment entrance during construction or remove the top 2 inches of soil after the site is stabililized. Stabilize the entire contributing drainage area, including the side slopes, before allowing any runoff to enter once construction is complete. ■ Place excavated material such that it can not be washed back into the basin if a storm occurs during construction of the facility. o Build the basin without driving heavy equipment over the infiltration surface. Any equipment driven on the surface should have extra-wide ("low pressure")tires. Prior to any construction, rope off the infiltration area to stop entrance by unwanted equipment. ■ After final grading, till the infiltration surface deeply. • o Use appropriate erosion control seed mix for the specific project and location. 2 of 8 California Stormwater BMP Handbook ]anuary 2003 New Development and Redevelopment www.cabmphandbooks.com Infiltration Basin TC- 11 • Performance As water migrates through porous soil and rock, pollutant attenuation mechanisms include precipitation, sorption, physical filtration, and bacterial degradation. If functioning properly, this approach is presumed to have high removal efficiencies for particulate pollutants and moderate removal of soluble pollutants.Actual pollutant removal in the subsurface would be expected to vary depending upon site-specific soil types. This technology eliminates discharge to surface waters except for the very largest storms; consequently, complete removal of all stormwater constituents can be assumed. There remain some concerns about the potential for groundwater contamination despite the findings of the NURP and Nightingale (1975; 1987a,b,c; 1989). For instance, a report by Pitt et al. (1994) highlighted the potential for groundwater contamination from intentional and unintentional stormwater infiltration. That report recommends that infiltration facilities not be sited in areas where high concentrations are present or where there is a potential for spills of toxic material. Conversely, Schroeder(1995) reported that there was no evidence of groundwater impacts from an infiltration basin serving a large industrial catchment in Fresno, CA. Siting Criteria The key element in siting infiltration basins is identifying sites with appropriate soil and hydrogeologic properties,which is critical for long term performance. In one study conducted in Prince George's County, Maryland(Galli, 1992), all of the infiltration basins investigated clogged • within 2 years. It is believed that these failures were for the most part due to allowing infiltration at sites with rates of less than 0.5 in/hr,basing siting on soil type rather than field infiltration tests, and poor construction practices that resulted in soil compaction of the basin invert. A study of 23 infiltration basins in the Pacific Northwest showed better long-term performance in an area with highly permeable soils (Hilding, 1996). In this study, few of the infiltration basins had failed after 10 years. Consequently, the following guidelines for identifying appropriate soil and subsurface conditions should be rigorously adhered to. ■ Determine soil type (consider RCS soil type`A, B or C' only)from mapping and consult USDA soil survey tables to review other parameters such as the amount of silt and clay, presence of a restrictive layer or seasonal high water table, and estimated permeability. The soil should not have more than 30% clay or more than 40%of clay and silt combined. Eliminate sites that are clearly unsuitable for infiltration. ■ Groundwater separation should be at least 3 in from the basin invert to the measured ground water elevation. There is concern at the state and regional levels of the impact on groundwater quality from infiltrated runoff, especially when the separation between groundwater and the surface is small. ■ Location away from buildings, slopes and highway pavement (greater than 6 m) and wells and bridge structures (greater than 30 m). Sites constructed of fill, having a base flow or with a slope greater than 15%should not be considered. ■ Ensure that adequate head is available to operate flow splitter structures (to allow the basin • to be offline)without ponding in the splitter structure or creating backwater upstream of the splitter. January 2003 California Stormwater BMP Handbook 3 of 8 New Development and Redevelopment www.cabmphandbooks.com TC- 11 Infiltration Basin • ■ Base flow should not be present in the tributary watershed. Secondary Screening Based on Site Geotechnical Investigation ■ At least three in-hole conductivity tests shall be performed using USBR 9300-89 or Bouwer- Rice procedures (the latter if groundwater is encountered within the boring), two tests at different locations within the proposed basin and the third down gradient by no more than approximately io m. The tests shall measure permeability in the side slopes and the bed within a depth of 3 m of the invert. ■ The minimum acceptable hydraulic conductivity as measured in any of the three required test holes is 13 mm/hr. If any test hole shows less than the minimum value, the site should be disqualified from further consideration. a Exclude from consideration sites constructed in fill or partially in fill unless no silts or clays are present in the soil boring. Fill tends to be compacted,with clays in a dispersed rather than flocculated state, greatly reducing permeability. ■ The geotechnical investigation should be such that a good understanding is gained as to how the stormwater runoff will move in the soil (horizontally or vertically) and if there are any geological conditions that could inhibit the movement of water. Additional Design Guidelines (t) Basin Sizing -The required water quality volume is determined by local regulations or sufficient to capture 85% of the annual runoff. (z) Provide pretreatment if sediment loading is a maintenance concern for the basin. (3) Include energy dissipation in the inlet design for the basins. Avoid designs that include a permanent pool to reduce opportunity for standing water and associated vector problems. (4) Basin invert area should be determined by the equation: A WQV kr where A= Basin invert area (m2) WQV=water quality volume (m3) k = 0.5 times the lowest field-measured hydraulic conductivity (m/hr) t = drawdown time (48 hr) (5) The use of vertical piping, either for distribution or infiltration enhancement shall • not be allowed to avoid device classification as a Class V injection well per 40 CFR146.5(e)(4)• 4 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Infiltration Basin TC- 11 • Maintenance Regular maintenance is critical to the successful operation of infiltration basins. Recommended operation and maintenance guidelines include: ■ Inspections and maintenance to ensure. ■ Observe drain time for the design storm after completion or modification of the facility to confirm that the desired drain time has been obtained. ■ Schedule semiannual inspections for beginning and end of the wet season to identify potential problems such as erosion of the basin side slopes and invert, standing water,trash and debris, and sediment accumulation. ■ Remove accumulated trash and debris in the basin at the start and end of the wet season. ■ Inspect for standing water at the end of the wet season. ■ Trim vegetation at the beginning and end of the wet season to prevent establishment of woody vegetation and for aesthetic and vector reasons. ■ Remove accumulated sediment and regrade when the accumulated sediment volume exceeds to% of the basin. ■ If erosion is occurring within the basin, revegetate immediately and stabilize with an erosion control mulch or mat until vegetation cover is established. ■ To avoid reversing soil development, scarification or other disturbance should only be performed when there are actual signs of clogging, rather than on a routine basis. Always remove deposited sediments before scarification, and use a hand-guided rotary tiller, if possible, or a disc harrow pulled by a very light tractor. Cost Infiltration basins are relatively cost-effective practices because little infrastructure is needed when constructing them. One study estimated the total construction cost at about$2 per It (adjusted for inflation)of storage for a 0.25-acre basin (SWRPC, 1991). As with other BMPs, these published cost estimates may deviate greatly from what might be incurred at a specific site. For instance, Caltrans spent about $18/ft3 for the two infiltration basins constructed in southern California, each of which had a water quality volume of about 0.34 ac.-ft. Much of the higher cost can be attributed to changes in the storm drain system necessary to route the runoff to the basin locations. Infiltration basins typically consume about 2 to 3%of the site draining to them,which is relatively small.Additional space may be required for buffer, landscaping, access road, and fencing. Maintenance costs are estimated at 5 to lo%of construction costs. One cost concern associated with infiltration practices is the maintenance burden and longevity. If improperly maintained, infiltration basins have a high failure rate. Thus, it may be necessary to replace the basin with a different technology after a relatively short period of time. • January 2003 California Stormwater BMP Handbook 5 of 8 New Development and Redevelopment www.cabmphandbooks.com TC- 11 Infiltration Basin ,References and Sources of Additional Information Caltrans, 2002, BMP Retrofit Pilot Program Proposed Final Report, Rpt.

Our scope of services was outlined in our proposal dated November 14, 2006 (KA Proposal No. PC122035-06) and May 20,2008 and included the following: • A site reconnaissance by a member of our engineering staff to evaluate the surface conditions at the project site. i • Review of selected published geologic maps, reports and literature pertinent to the site and surrounding area. 1 Offices Serving The Western United States 4221 Brickell Street,Ontario,California 91761 •(909)974-4400•Fax:(909)974-4022 12206026-final revised 091108 KA No. 122-06026 Page No.2 • A field investigation consisting of drilling eight (8) soil borings to depths ranging from approximately 20 to 50 feet below the existing ground surface for evaluation of the subsurface conditions at the project site as well as drilling additional two (2) Cone Penetration Test (CPT) borings to a depth of approximately 60 feet for liquefaction evaluation. • Four (4) shallow borings were drilled within the existing parking and drive areas for documentation of the asphaltic concrete(AC)pavement sections. • Four(4) shallow borings,up to I 1 feet deep,were drilled within the vacant portion of the lot east of the existing store for top soil and sub-surface soil evaluation. • Four (4) shallow test pits, three feet and six feet deep, were excavated and double ring Infiltrometer testing per ASTM D 3385 tests performed per test pit. • Performing laboratory tests on representative soil samples obtained from the borings to evaluate the physical and index properties of the subsurface soils. • Evaluation of the data obtained from the investigation and engineering analyses of the data with respect to the geotechnical aspects of structural design,site grading and paving. • Preparation of this report summarizing the findings,results, conclusions and recommendations of our investigation. • Environmental services, such as chemical analyses of soil and groundwater for possible environmental contaminates, and geologic study were not in our scope ofservices. PROPOSED CONSTRUCTION Based on our review of the site plan and our discussions with the project representative, we understand that the proposed project will include expansion of an existing Wal-Mart Store. The Wal-Mart building will expand from the current 149,723 square feet to approximately 221,537 square feet. The Wal-Mart building superstructure will be a combination of concrete masonry shear walls and steel columns supporting a roof structure of steel joist girders and steel joists. The floor slab will be structurally connected to the perimeter walls with dowels. The typical bay spacing between columns is approximately 55 feet by 48 feet. The typical gravity load at an interior column is 85 kips. The estimated maximum gravity load that may occasionally occur due to severe live loading is 150 kips. Maximum column uplift force from wind is estimated at 30 kips. The estimated typical exterior column gravity load is 50 kips. Concrete masonry walls are estimated to have gravity loads of 1.5 to 2.0 kips per lineal foot for non-load bearing walls and 4.0 to 6.0 kips per lineal foot for load bearing walls. Estimated maximum uniformly distributed floor slab live load is 125 pounds per square foot (psf), with maximum concentrated load of 5.0 kips. Paving consisting of asphalt concrete (flexible) will cover the majority of the site, with Portland cement concrete (rigid) in truck dock areas. Underground utility construction will be required to provide water, gas and electric services, and storm and sanitary sewer lines. Mass grading of the majority of the site is Krazan&Associates,Inc.

In the event these structural or grading details are inconsistent with the final design criteria, we should be notified so that we can evaluate the potential impacts of the changes on the recommendations presented in this report and provide an updated report as necessary. SITE LOCATION AND SITE DESCRIPTION The site is irregular in shape and encompasses approximately 19.96± acres. The site is located on the southwest comer of Temecula Parkway(Route 79) and Apis Road in the unincorporated Temecula area of the County of Riverside, California (see Vicinity Map, Figure 1). Presently, the existing Wal-Mart store is open for business. The site is predominately surrounded by residential and commercial developments. The majority of the site is relatively level with no major changes in grade. The finished floor elevation of the building pad is approximately 1,071.82 feet above mean sea level. SITE INVESTIGATION GEOLOGIC SETTING • The site is located within the Peninsular Range Geomorphic Province, an area characterized by active northeast trending strike slip faults, including the San Jacinto to the northwest, and the Elsinore to the southwest. Locally, the subject site is within the upland area just east of the Temecula Valley and is primarily underlain by shallow relatively soft sedimentary bedrock of the Pauba formation. Drainage from the site flows southwestwards into Temecula Creek. The project site is situated between the Santa Rosa Mountains and the San Jacinto Mountains to the east; and Santa Ana Mountains to the west and south. The near-surface deposits in the vicinity of the subject site are indicated to be comprised of recent alluvium consisting of unconsolidated sands, silt, and clays derived from erosion of local mountain ranges. Deposits encountered on the subject site during exploratory drilling are discussed in detail in this report. The site is located in a seismically active area of Southern California. The nearest significant active fault is the Elsinore-Temecula Fault zone (Type B fault), which is approximately 2.9 kilometers away. The nearest Type A fault is the Elsinore-Julian Fault zone, which is approximately 13.8 kilometers away. The area in consideration shows no mapped faults on-site according to maps prepared by the California Division of Mines and Geology (now '.mown as the California Geologic Survey) and published by the International Conference of Building Officials (ICBG). No evidence of surface faulting was observed on the property during our reconnaissance. The site is located within a Seismic Zone 4. i Krazan&Associates.Inc.

KA No. o Pageage NNo..4 4 FIELD AND LABORATORY INVESTIGATIONS Subsurface soil conditions were explored by drilling eight (8) soils borings and two (2) CPT borings to depths ranging from approximately 20 to 60 feet below existing site grade. In addition, four(4) shallow borings were drilled within the parking and drive areas for documentation of the pavement sections. The approximate boring locations are shown on the Site Plan,Figure 2. These approximate boring locations were estimated in the field based on pacing and measuring from the limits of existing site features. During drilling operations, penetration tests were performed at regular intervals to evaluate the soil consistency and to obtain information regarding the engineering properties of the subsurface soils. Soil samples were retained for laboratory testing. The soils encountered were continuously examined and visually classified in accordance with the Unified Soil Classification System. A more detailed description of the field investigation is presented in Appendix A. Laboratory tests were performed on selected soil samples to evaluate their physical characteristics and engineering properties. The laboratory-testing program was formulated with emphasis on the evaluation of natural in-situ moisture and density, gradation, shear strength, consolidation and expansion potential, R-value, maximum dry density, resistivity, pH value, sulfate and chloride contents of the materials encountered. Details of the laboratory-testing program are discussed in Appendix A. The results of the laboratory tests are presented on the borings logs or on the test reports, which are also included in Appendix A. This information, along with the field observations, was used to prepare the final boring logs in Appendix A. SOIL PROFILE AND SUBSURFACE CONDITIONS Based on our findings, the subsurface conditions encountered appear typical of those found in the geologic region of the site. The subsurface soils encountered at the site generally consisted of alluvial silty sand and sand with thin layers of sandy silt and silty clay. Fill materials may be present onsite between our exploratory borehole locations since the site was previously graded. Verification of the extent of fill shall be determined by the soil engineer of record during site grading. Fill soils which have not been properly compacted and certified shall be excavated and recompacted at the soil engineer of record direction. Below the fill soils,alluvial silty sand and sand were encountered. Field and laboratory tests suggest that these soils are moderately strong and slightly compressible. Penetration resistance, measured by the number of blows required to drive a Modified California sampler or a Standard Penetration Test (SPT) sampler, ranged from 4 to 70 blows per foot. Dry densities ranged from 120.8 to 124.3 pcf. Representative soil samples consolidated approximately 0.8 to 1.1 percent under a 2-ksf load when saturated. Representative soil samples bad angles of internal friction of 33 to 35 degrees. Representative near-surface soil samples had Expansion Indices of 8 to 18. A representative soil sample had a maximum 's dry density of 131.5 pcf and an R-Value of 34.

Groundwater was encountered at a depth of 30 feet below existing grade during this time of investigation. It should be recognized that water table elevation might fluctuate with time. The 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, irrigation practices at the site and in the surrounding areas, climatic conditions, flow in adjacent or nearby canals,pumping from wells and possibly as the result of other factors that were not evident at the time of our investigation. Therefore, water level observations at the time of our field investigation may vary from those encountered during the construction phase of the project. The evaluation of such factors is beyond the scope of this report. Long-term monitoring in observation wells, sealed from the influence of surface water, is often required to more accurately define the potential range of groundwater conditions on a site. PERCOLATION TESTING Percolation tests were conducted in accordance with the criteria set in the "County of Riverside, Department of Environmental' Guidelines and the U.S. Bureau of Water Reclamation guidelines. Results of the falling head tests are presented in the attachments to this report. The data, which is presented in tabular and graphic format, indicates varied percolation rates with changing pressure head and within the varying soil strata at the site. The soil absorption or percolation rates are based on tests 3 Krazan&Associates,Inc. Offices Scrving The Western United States .1 12206026-I nal revised 091108 `i KA No. 122-06026 Page No.6 conducted with clear water. The infiltration rates may vary with time as a result of soil clogging from water impurities. A factor of safety should be incorporated into the design of the basins to compensate for these factors. In addition, periodic maintenance consisting of clearing the bottom of the basins of clogged soils should be expected. The highest percolation rate at the end of the test for each boring ranges from 1.5 inches to 2.3 inches per hour. A minimum factor of safety of 2.0 shall be assigned to this value. Subsequent Percolation testing was conducted on August 26, 2008 using a Double Ring Infiltrometer following ASTM 3385. The percolation rates determined using this test method produce rates of 0.5 to 0.8 inchers per hour (1 to 2 cm/hr). The recommended design percolation rate shall be a maximum of 0.75 inches per hour(2 cm/hr). GROUND SHAKING Although ground rupture is not considered to be a major concern at the subject site,the site will likely be subject to at least one moderate to severe earthquake and associated seismic shaking during its lifetime, as well as periodic slight to moderate earthquakes. Some degree of structural damage due to stronger seismic shaking should be expected at the site, but the risk can be reduced through adherence to seismic design codes. Surface ground motions based on the USGS information requires modification to address the presence of deep alluvial soils, such as those found at the subject site. Based on California Geological Survey, Probabilistic Seismic Hazards Mapping,the horizontal Peak Ground Acceleration(PGA) is anticipated to be 0.554g for a 10% probability of being exceeded in 50 years resulting from a maximum magnitude earthquake of 6.8. SEISMICITY AND LIQUEFACTION POTENTIAL Soil liquefaction is a state of soil particle suspension caused by a complete loss of strength when the effective stress drops to zero. Liquefaction normally occurs under saturated conditions in soils such as sand in which the strength is purely frictional. However, liquefaction has occurred in soils other than clean sand. Liquefaction usually occurs under vibratory conditions such as those induced by seismic events. To evaluate the liquefaction potential of the site,the following items were evaluated: 1) Soil type 2) Groundwater depth 3) Relative density 4) Initial confining pressure 5) Intensity and duration of ground shaking The predominant soils within the project site consist of loose to medium dense silty sand and sand. Low to very low cohesion strength is associated with the sandy soil. Groundwater was encountered at a depth of 30 feet below existing site grade during our field investigation and the maximum possible high groundwater depth of 20 feet is anticipated according to the County of Riverside General Plan Safety i • Element adopted October 7,2003. Krazan&Associates,Inc. Offices Serving The Western United States 12206026-final revised 091108 KA No. 122-06026 Page No.7 The site was evaluated for liquefaction potential using the LiquefyPm computer program (version 4.5b) developed by CivilTech. The liquefaction analysis indicated that the sandy soils below the existing grade had a moderately high potential for liquefaction under seismic conditions. SEISMIC INDUCED SETTLEMENT One of the most common phenomena during seismic shaking accompanying any earthquake is the induced settlement of loose unconsolidated soils. Based on site subsurface conditions, and the moderate seismicity of the region, any loose fill materials at the site could be vulnerable to this potential hazard. However, this hazard can be mitigated by following our Geotechnical Engineering Recommendations (over-excavation and rework of disturbed soils and/or loose fill materials). The sandy soils encountered will be subject to seismic settlement. Based on our calculation,the total and differential seismic induced settlement, prior to site mitigation is expected to be approximately 2.7 inches and 1.4 inches, respectively. SOIL CORROSIVITY Corrosion tests were performed to evaluate the soil corrmsivity to the buried structures. The tests consisted of sulfate content,c1doride content,and resistivity and the results of the tests are included as follows: Parameter Results W TestMethod` • Resistivity 2,220 ohms-em CALTRANS Sulfate 340 ppm EPA 9038 Chloride 389 ppm EPA 9253 pH 8.27 EPA 9045C EXISTING PAVEMENT SECTIONS The existing asphaltic concrete (AC) pavement sections were documented at four (4) random locations using a truck-mounted drill rig.

Offices Serving The Westem United States 12206026-final revised 091108 KA No. 122-06026 • Page No.8 CONCLUSIONS AND RECOMMENDATIONS Based on the findings of our field and laboratory investigations, along with previous geotechnical experience in the project area, the following is a summary of our evaluations, conclusions, and recommendations. ADMINISTRATIVE SUMMARY Based on the data collected during this investigation, and from a geologic and geotechnical engineering standpoint, it is our opinion that the proposed improvements may be trade as presently planned provided that the recommendations presented in this report are considered in the design and construction of the project. Subsurface conditions that trust be considered in both design and construction include existing structures,underlying fill materials,and liquefaction potential. Associated with the existing development are buried footings and utility lines. These buried structures (footings and utility lines, etc.) shall be properly removed and the resulting excavations backfilled with Engineered Fill. Any other buried structures encountered during construction should be removed and backfilled in accordance with the recommendations of the Soils Engineer. The site has been previously graded for the existing development. Fill materials may be present onsite • between our exploratory borehole locations. The consistency of the fills should be verified during site construction. A minimum of 95 percent relative compaction based on ASTM D1557 is required for the foundation soils underneath the building pad. A seismic hazard, which could cause damage to the proposed development during seismic shaking,is the post-liquefaction settlement of the liquefied sands and silts. Liquefaction potential at the site was evaluated using the "LIQUEFYPRO" computer program developed by CivilTech Corporation. Based on our evaluation, the potential for liquefaction at the site is moderately high. Mitigation measures are recommended to minimize structural damage due to liquefaction. The potential for structural damage at the site can be minimized by using geogrid, stone columns, or supporting the building on a deep foundation system. Geogrid is a commonly used method and our suggested option to reduce structural damage due to liquefaction. The geogrid reinforcement should be placed in layers along with the fill material. Recommendations for the geogrid system are provided herein. Site preparation, mitigation measures, and foundation recommendations are provided herein for the geogrid system for the proposed building. It is anticipated that the structural elements within the parking lot may settle, due to liquefaction. Therefore, it is recommended that flexible connectors be incorporated with utilities placed at the transition between the building and the exterior sub-grade. Krazan&Associates,Inc. .l Offices Serving The Western United Stares 12206026-final revised 091108 a KA No. 122-06026 Page No.9 Sandy soil conditions were encountered at the site. These cohesionless soils have a tendency to cave in trench wall excavations. Shoring or sloping back trench sidewalls may be required within these sandy soils. The shrinkage on recompacted soil and fill placement is estimated at 5 to 10 percent. This value is an estimate and may vary significantly depending on several items including soil conditions, compaction effort, weather, etc. Subsidence within building areas, below the recompaction depth, is estimated to be less than 0.01 feet, due to the recommended over-excavation. Subsidence within parking areas; below the recompaction depth, is estimated to be less than 0.05 feet. All grading and earthwork should be performed in accordance with the Grading Ordinances of the City of Temecula and the applicable portions of the Earthwork Specifications in Appendix B,except as modified herein. GROUNDWATER INFLUENCE ON STRUCTURES/CONSTRUCTION Based on our findings and historical records, it is not anticipated that groundwater will rise within the zone of structural influence or affect the construction of foundations and pavements for the project. However, if earthwork is performed during or soon after periods of precipitation, the subgrade soils may become saturated, "pump," or not respond to densification techniques. Typical remedial measures include: discing and aerating the soil during dry weather; mixing the soil with dryer materials; removing and replacing the soil with an approved fill material; or mixing the soil with an approved lime or cement product. Our firm should be consulted prior to implementing remedial measures to observe the unstable subgrade conditions and provide appropriate recommendations. WEAK AND DISTURBED SOILS Of primary importance in the development of this site is the removal/recompaction of potentially compressible soils from the areas of the proposed structures. This is discussed in detail in the Earthwork section of this report. EARTHWORK Site Preparation—Clearing and Stripping General site clearing shall include removal of vegetation and existing utilities; structures; including foundations basement walls and floors; trees and associated root systems; rubble; rubbish; and any loose and/or saturated materials. Site stripping shall extend to a minimum depth of 2 to 4 inches, or until all organics in excess of 3 percent by volume are removed. Deeper stripping may be required in localized areas. These materials will not be suitable for reuse as Engineered Fill. However, stripped topsoil may be stockpiled and reused in landscape or non-structural areas. Any excavations that result from clearing operations shall be backfilled with engineered fill. Krazan & i Associates' field staff shall be present during site clearing operations to enable us to locate areas where depressions or disturb soils are present and to allow our staff to observe and test the backfill as it is placed. If site clearing and backfilling operations occur without appropriate observation and testing by a Krazan&Associates,Inc. Offices serving The Western United States 12206026-final revised 091108 >� KA No. 122-06026 Page No. 10 qualified geotechnical consultant, there may be the need to over-excavate the building areas to identify uncontrolled fills prior to mass grading of the building pads. As with site clearing operations, any buried structures encountered during construction shall be properly removed and backfilled. The resulting excavations shall be backfilled with engineered fill. Liquefaction Mitigation Subsurface soils within the site are prone to liquefaction under high ground shaking acceleration during an earthquake. Our calculations indicated that the building areas, and at least five feet (5') beyond, if permissible, should be over-excavated to a depth of six feet (6') below finish grade or four feet (4') below proposed footings, whichever is greater, and the resulting excavation be backfilled with a layered system of Engineered Fill and geogrid reinforcing fabric. Deeper overexcavation and recompaction will be required should unsuitable fill soils are encountered. The depth of the over-excavation shall be measured from existing ground or rough pad grade,whichever is greater. A design procedure is provided below. Global seismic induced settlement of the site is still anticipated when liquefaction occurs. Prior to placing the geogrid,the bottom of the subgrade shall be scarified to a depth of 8 inches,moisture conditioned to near optimum moisture, and recompacted to a minimum of 95 percent relative compaction based on ASTM D1557. The first layer of geogrid reinforcement will be placed directly on the prepared subgrade at a depth of six feet (6') below finish grade. The geogrid material shall be overlapped a minimum of three feet (3') in all directions. The geogrid strips shall be"shingled" such that the exposed geogrid edge is opposite the direction of fill placement (as roof shingles to rain runoff). The interlock between the geogrid and Engineered Fill will provide load transfer. No vehicles may traverse the geogrid prior to placement of the Engineered Fill cover. The next layer of geogrid shall be placed on top of the compacted Engineered Fill. This and subsequent layers need only be overlapped a minimum of one foot (1')on all sides. The geogrid strips of this layer, and all subsequent layers within the footprint, shall be placed with lengths perpendicular to those in the layer immediately below. The fill soils excavated from the area beneath the structure may be moisture conditioned and recompacted between geogrid layers as reinforced fill. The reinforced fill should be moisture conditioned to near optimum moisture content and recompacted to a minimum of 95 percent of the maximum dry density based on ASTM D 1557 Test Method. A total of 4 geogrid layers, including the layer at the base of the excavation should be installed at vertical increments of one foot (1'). The geogiid layers shall extend to a minimum of five feet (5') beyond, if permissible, the exterior footing perimeter of the structure. The geogrid reinforcement fabric shall consist of Tensar® BX 1100 Geogrid*. Any additional unstable soils within building areas shall be excavated and backfilled with Engineered Fill. It is recommended that the entire site be excavated at once,and soils be stockpiled on adjacent or nearby properties. The geogrid and excavated soil may then be placed and recompacted as recommended herein. Alternatively, the contractor may elect to excavate the site in two stages, where excavated soil can be stockpiled over one-half of the site while the other half is mitigated. However, if the contractor elects the option of two stages over the preferred option of using one stage, a minimum of five feet(5') of Geogrid 'Tensar may be contacted at[(949)661-2229 or(714)281-7883]. Krazan&Associates.Inc. Offices Serving nic Western United States 12206026-final revised 091108 KA No. 122-06026 Page No. 11 from the first half shall overlap the second half. Furthermore, the overlapping geogrid should be protected from damages, which may be caused by operating equipment. It is further recommended that flexible utility connections be used for the project. In lieu of the geogrid reinforcement method, the buildings may be supported on a deep foundation system or a structural slab system. Recommendations for a deep foundation system or a structural slab system may be provided to the client by Krazan&Associates,Inc.upon request. ENGINEERED FILL Engineered Fill is defined as soil that has an organic content of less than 3 percent by volume that has been properly blended, moisture conditioned and compacted as recommended in this report, and that has been observed and tested by a qualified geotechnical engineering consultant to document compliance with the project requirements. The organic-free, on-site, upper soils are predominately silty sand and sand. These soils will be suitable for reuse as Engineered Fill, provided they are cleansed of excessive organics and debris. The soils with Expansion Index (EI) greater than 20 shall not be used within the upper two feet of the building pad and exterior flatwork areas. The preferred materials specified for Engineered Fill are suitable for most applications with the . exception of exposure to erosion. Project site winterization and protection of exposed soils during the construction phase should be the sole responsibility of the contractor, since he has complete control of the project site at that time. Imported Fill material shall be predominately non-expansive granular material with a plasticity index less than 10 and an Expansion Index less than 20. Imported Fill shall be free from rocks and clods greater than 4 inches in diameter. All Imported Fill material shall be submitted to the Soils Engineer for approval at least 48 hours prior to delivery at the site. Fill soils shall be placed in lifts approximately 6 inches thick, moisture-conditioned as necessary, and compacted to achieve at least 95 percent of the maximum dry density as determined by ASTM D1557 Test Method. Additional lifts shall not be placed if the previous lift did not meet the required dry density or if soil conditions are not stable. All proposed fill material, whether from on-site or import, shall be submitted to the Geotechnical Engineer for approval for the proposed use at least 72 hours prior to delivery to the site or earth moving activities. The preferred materials specified for engineered fill are appropriate for most applications with the exception of areas where erosion is a consideration. Project site winterization and protection of exposed soils during the construction phase shall be the sole responsibility of the contractor, since he has complete control of the project site at that time. a i i Krazan&Associates,Inc.

The infiltration basin is to be located in the center medium, along the east side of the expansion area of the existing store, between the two parking areas. TEMPORARY EXCAVATION STABILITY All excavations should comply with the current requirements of Occupational Safety and Health Administration (OSHA). All cuts greater than 2 feet in depth shall be sloped or shored. Temporary excavations shall be sloped at 1:1 (horizontal to vertical) or flatter, up to a maximum depth of 6 feet and at 1 Y6:1 (horizontal to vertical) to a maximum depth of 10 feet. Heavy construction equipment, building materials, excavated soil, and vehicular traffic shall not be allowed within five feet of the top (edge) of the excavation. Where sloped excavations are not feasible due to site constraints, the excavations may require shoring. The design of the shoring system is normally the responsibility of the contractor or shoring designer, and therefore, is outside the scope of this report. However,the logs of borings presented with this report may be used for factual data such as soil types encountered at the location of each particular boring and at the indicated depths. Interpolation between the exploratory borings is at the user's own risk. Design work for shoring system shall be performed by an engineer with expertise in shoring systems. The design of • the temporary shoring shall take into account lateral pressures exerted by the adjacent soil, and, where anticipated, surcharge loads due to adjacent buildings and any construction equipment or traffic expected to operate alongside the excavation. Slope height, slope inclination, or excavation depth should in no case exceed those specified in local, state, or federal safety regulation, (e.g. OSHA) standards for excavations, 29 CFR part 1926, or Assessor's regulations. Where disturbed soil or uncontrolled fills are present, the contractor shall be prepared to install shoring or flatten the excavation slopes. The excavation/shoring recommendations provided herein are based on soil characteristics derived from the test borings within the area. Variations in soil conditions will likely be encountered during the excavations. Krazan & Associates, Inc. shall be afforded the opportunity to provide field review to evaluate the actual conditions and account for field condition variations,not otherwise anticipated in the preparation of this recommendation. UTILITY TRENCD LOCATION,CONSTRUCTION AND BACKFILL To maintain the desired support for new foundations, new utility trenches shall be located such that the base of the trench excavation is located above an imaginary plane having an inclination of 1.0 horizontal to 1.0 vertical, extending downward from the bottom edge of the adjacent footing. Utility trenches shall be excavated according to accepted engineering practices following OSHA standards by a contractor experienced in such work. The responsibility for the safety of open trenches shall be home by the contractor. Traffic and vibration adjacent to trench walls shall be kept to a minimum; cyclic wetting and drying of excavation side slopes shall be avoided. Depending upon the location and depth of some utility t Krazan&Associates,Inc. Offices Serving The Western United States 12206026-final revised 091108 . . . .. . ...................... 26 ICA No. gNo. 13 Page No. 13 trenches, groundwater flow into open excavations could be experienced, especially during or shortly following periods of precipitation. For purposes of this section of the report, backfill is defined as material placed in a trench starting one foot above the pipe; bedding and shading (also referred to as initial backfill) is all material placed in a trench below the backfill. With the exception of specific requirements of the local utility companies or building department, pipe bedding and shading shall consist of clean medium-grained sand. The sand shall be placed in a damp state and shall be compacted by mechanical means prior to the placement of backfill soils. Above the pipe zone, underground utility trenches may be backfilled with either free- draining sand, on-site soil or imported soil. The trench backfill should be compacted to at least 95 percent relative compaction based on ASTM D1557. COMPACTED MATERIAL ACCEPTANCE Compaction specifications are not the only criteria for acceptance of the site grading or other such activities. However, the compaction test is the most universally recognized test method for assessing the performance of the Grading Contractor. The numerical test results from the compaction test cannot be solely used to predict the engineering performance of the compacted material. Therefore,the acceptance of compacted materials will also be dependent on the moisture content and the stability of that material. The Geotechnical Engineer has the option of rejecting any compacted material regardless of the degree of compaction if that material is considered to be too dry or excessively wet, unstable or if future instability is suspected. A specific example of rejection of fill material passing the required percent compaction is a fill which has been compacted with in-situ moisture content significantly less than optimum moisture. Where expansive soils are present, heaving of the soils may occur with the introduction of water. Where the material is a lean clay or silt, this type of dry fill (brittle fill) is susceptible to future settlement if it becomes saturated or flooded. SURFACE DRAINAGE AND LANDSCAPING The ground surface should slope away from building and pavement areas toward appropriate drop inlets or other surface drainage devices. We recommended that adjacent paved exterior grades be sloped a minimum of 2 percent for a minimum distance of 5 feet away from structures. Ideally, asphalt concrete pavement areas shall be sloped at a minimum of 2 percent, with Portland cement concrete sloped at a minimum of one percent toward drainage structures. These grades shall be maintained for the life of the project. Roof drains shall be designed to avoid discharging into landscape areas adjacent to the building. Downspouts shall be directed to discharge directly onto paved surfaces to allow for surface drainage into the storm systems or shall be connected directly to the on-site storm drain. FOUNDATION The proposed structures may be supported on a shallow foundation system bearing on geogrid reinforced Engineered Fill. Spread and continuous footings can be designed for the following maximum allowable soil bearing pressures: Krazan&Associates,Inc. Offices Serving The western United States 12206026-final revised 091 108 KA No. 122-06026 Page No. 14 "; a � o'er ,•=,,.xF Dead Load Only 2,400 psf Dead-Plus-Live Load 2,800 psf Total Load, including wind or seismic loads 3,700 psf The footings shall have a minimum depth of 18 inches below pad subgrade (soil grade) or adjacent exterior grade,whichever is deeper. New footings adjacent to existing buildings should not be embedded shallower than the existing footings. Minimum footing widths should be 15 inches for continuous footings and 24 inches for isolated footings. The footing excavations shall not be allowed to dry out any time prior to pouring concrete. Any permanent connections between the proposed additions and the existing building should be made after primary structure loads are applied to the proposed building foundations. Settlement Provided the site is prepared as recommended and that the foundations are designed and constructed in accordance with our recommendations, the total settlement due to foundation loads is not expected to exceed 1 inch. The differential settlements are anticipated to be less than '%-inch between adjacent columns and perimeter walls to adjacent columns, and less than %x-inch in 40 feet along perimeter walls. Most of the settlement is expected to occur during construction as the loads are applied. However, additional post-construction settlement may occur if the foundation soils are flooded or saturated. Lateral Load Resistance Resistance to lateral footing displacement can be computed using an allowable friction factor of 0.45 acting between the base of foundations and the supporting subgrade. Where a vapor barrier material is used below concrete slabs-on-grade, a coefficient of friction shall be provided by the vapor barrier manufacturer. Lateral resistance for footings can alternatively be developed using an allowable equivalent fluid passive pressure of 350 pounds per cubic foot acting against the appropriate vertical footing faces. Where equivalent fluid pressure against the sides of the footings or embedded slab edge are to be used, the footing or slab edge must be cast directly against undisturbed soils or the soils surrounding the structure must be recompacted to the requirements for engineered fill presented above. The frictional and passive resistance of the soil may be combined without reduction in determining the total lateral resistance. A one-third increase in the value above may be used for short duration, wind, or seismic loads. CONCRETE FLOOR SLABS Slabs subject to structural loading may be designed utilizing a modulus of subgrade reaction (K) of 150 pounds per square inch per inch (psi/in). The K value was approximated based on inter-relationship of soil classification and bearing values (Portland Cement Association,Rocky Mountain Northwest). For exposed concrete slabs and slabs with tile flooring, a minimum 4-inch layer of base should be provided underneath the slab. The subbase should consist of 4 inches of coarse aggregate base material Krazan&Associates,Inc. Offices Serving The Western United States 12206026-Gnal revised 091108 KA No. 122-06026 Page No. 15 equal to ASTM D448, No. 467, 57 or 67 with crushed, interlocking rock fines or crusher ran road base with rock fines or a similar locally available material that can be specified by a DOT gradation number. EXTERIOR FLATWORK Exterior slabs should be cast free of the adjacent building foundation in order to act independently of the walls and foundation system in all areas except doorways leading into the building. This may be accomplished by using a strip of a �-inch thick asphalt impregnated felt divider material between the slab edges and the adjacent structure. Where floating slabs-on-grade are not desired due to the need for vertical control such as at doorways,dowel bars may be considered. There is a potential drawback to the use of dowel bars for slabs; there is a potential that a crack may develop parallel to the edge of the slab about two to four feet back of the edge. Exterior finish grades should have a minimum slope gradient of 1 to 1'/2 percent away from the buildings to preclude ponding of water adjacent to the structures. Frequent construction or control joints should be provided in all concrete slabs where cracking is objectionable. Joint spacing should not exceed 30 times the slab thickness. Control joints, whether scored or saw-cut should be no less than one-fourth of the slab thickness. Continuous reinforcing or dowels at the constriction and control joints will also aid in reducing uneven slab uplift. Exterior flatwork will be subjected to edge effects due to the fluctuation in the moisture content of the subgrade soils along the outer edges of the slab. Deepened edge sections(also referred to as down turned • curbs) and controlled irrigation of landscaped areas adjacent to the flatwork will aid in reducing the potential for the shrinkage and swelling of the underling soils.By deepening the edge section of concrete flatwork a minimum of 12 inches below the subgrade soils,there is less potential for soil moisture change below at least the perimeter of the slabs. By maintaining the soil moisture content, the resulting soil displacement or shrink/swell cycles will also be reduced. RETAINING WALLS For retaining walls with level ground surface behind the walls, we recommend that retaining walls capable of deflecting a minimum of 0.1 percent of its height at the top be designed using an equivalent fluid active pressure of 35 pounds per square foot per foot of depth. Walls that are incapable of this deflection or walls that are fully constrained against deflection may be designed for an equivalent fluid at-rest pressure of 55 pounds per square foot per foot per depth. This is anticipated to apply to the loading dock walls. A passive lateral pressure of 350 pounds per square foot may be used to calculate sliding resistance. If walls are to be constructed above descending slopes,our office shall be contacted to discuss further reduction in allowable passive pressures for resistance of lateral forces, and for overall retaining wall foundation design. The surcharge effect from loads adjacent to the walls shall be included in the wall design. The surcharge load for walls capable of deflecting (cantilever walls), we recommend applying a uniform surcharge r pressure equal to one-third of the applied load over the full height of the wall. Where walls are restrained the surcharge load shall be based on one-half of the applied load above the wall, also distributed over the full height of the wall. For other surcharges,such as from adjacent foundations,point • loads or line loads,Krazan&Associates should be consulted. { { I Krazan&Associates,Inc.

The zone of non-expansive backfill material shall extend from the bottom of each retaining wall laterally back a distance equal to the height of the wall,to a maximum of five(5)feet. The active and at-rest earth pressures do not include hydrostatic pressures. To reduce the build-up of hydrostatic pressures, drainage shall be provided behind the retaining walls. Wall drain shall consist of a minimum 12-inch wide zone of drainage material, such as aq-inch by%6-inch drain rock wrapped in a non- woven polypropylene geotextile filter fabric such as Mirafi 140N or equivalent. Alternatively, drainage may be provided by the placement of a commercially produced composite drainage blanket, such as Miradmin, extending continuously up from the base of the wall. The drainage material shall extend from the base of the wall to finished subgrade in paved areas and to within about 12 inches below the top of the wall in landscape areas. In landscape areas the top 12 inches shall be backfilled with compacted native soil. A 4-inch minimum diameter, perforated, Schedule 40 PVC drain pipe shall be placed with holes facing down in the lower portion of the wall drainage material,surrounded with drain rock wrapped in filter fabric. A solid drainpipe leading to a suitable discharge point shall provide drainage outlet. As an alternative,weep holes may be used to provide drainage. If weep holes are used, the weep holes shall be 3 inches in diameter and spaced about 8 feet on centers. The backside of the weep holes shall be covered with a corrosion-resistant mesh to prevent loss of backfill and/or drainage material. PAVEMENTDESIGN Wal-Mart requirements for pavement design are as follow: "Paving shall be design using the `AASHTO Guide for Design of Pavement Structures 1993...." "In a state where the highway department has developed a unique, state-approved method of pavement design, that unique method will be accepted only for a project in that state." Based on the established standard practice of designing flexible pavements in accordance with State of California Department of Transportation (Caltrans) for projects within California, we have developed pavement sections in accordance with the procedure presented in Caltrans Standard Test Method 301. This pavement design procedure is based on the volume of traffic (Traffic Index) and the soil resistance"R"value (Resistance Value). The AASHTO procedure was used to evaluate rigid pavement section requirements. In accordance with Wal-Mart Stores, Inc., criteria, we understand that concrete and asphalt concrete pavement should be designed for Standard Duty and Heavy Duty traffic loading based on equivalent 18 kip axle loads of 109,500 (ESAL) and 335,800 (ESAL)respectively,and a design life of 20 years. Caltrans provides a conversion equation to convert ESAL to TI. The equation, which is based on a mix of traffic, is: TI = 9•(ESAL/106)0119. Based on this equation, the Traffic Indexes that correspond to the Standard Duty and Heavy Duty traffic loadings are 7.0 and 8.0 respectively. Existing Pavement Section The existing asphaltic concrete (AC) pavement sections were docrunented at four (4) random locations using a truck-mounted drill rig. The approximate boring locations are shown on the Site Plan, Figure 2. j The pavement sections are presented as follows: Krazan&Associates,Inc.

Although not specifically addressed in the Wal-Mart document "Geotechnical Investigation Specifications and Report Requirements," with the vast parking areas and the amount of import required to construct layered pavement sections incorporating aggregate base, a Light Duty pavement may be appropriate for consideration in automobile parking areas. Based on our experience with pavement design for retail centers, we recommend a minimum Traffic Index of 5.5 for design of pavements for automobile parking lots and drive lanes. Based on a review of the boring logs and the R-value data presented above, the near surface soil of the site consists of mostly silty sand with various amount of clay. Therefore, an R-value of 34 is considered to be representative for the pavement. If site grading exposes soil other than that assumed, we shall perform additional tests to confirm or revise the recommended pavement sections for actual field conditions.

Unless otherwise required by local jurisdictions, paving materials should comply with the materials specifications presented in the Caltrans Standard Specifications Section. Class 2 aggregate shall comply with the materials requirements for Class 2 base found in Section 26. The mineral aggregate shall be Type B, V2-inch or '/-inch maximum, medium grading, for the wearing course and 1/4-inch maximum,medium grading for the base course, and shall conform to the requirements set forth in Section 39 of the Standard Specifications. The asphalt concrete materials shall comply with and be placed in accordance with the specifications presented in Section 39 of the Caltrans Standard Specifications,latest edition. Asphalt concrete shall be compacted to a minimum of 96 percent of the maximum laboratory compacted(kneading compactor)unit weight. ASTM Test procedures and shall be used to assess the percent relative compaction of soils, aggregate base and asphalt concrete. Aggregate base and subbase, and the upper 12 inches of subgrade shall be compacted to at least 95 percent based on the Modified Proctor maximum compacted unit weight obtained in accordance with ASTM test method D1557-00. Compacted aggregate base shall also be stable and unyielding when proof-rolled with a loadedten-wheelwater truck or dump truck. Alternative Pavement Rehabilitation As an alternative to the removal of the existing pavement and replacement of new pavement section, a Petromat system may be used to reduce the cost. This rehabilitation method shall be approved by Wal- Mart and the project Civil Engineer. The existing pavements consist of approximately 3 inches of asphalt concrete(AC)over 4.5 to 5.0 inches of aggregate base (AB). The restoration of the existing pavement for the proposed development may be conducted as follows: Mill the existing pavement to a depth of 1.5 inches. Any severe cracking and unsuitable areas shall be removed to the AB and replaced with AC to the elevation of the milled surface. Recompaction of the existing AB may be required prior to placing AC. Cracks from 1/8 to 3/8 inch shall be filled with a liquid crack sealant. Cracks larger than 3/8 inch shall be filled with a more stable crack filler, such as hot or cold asphalt mix or emulsion slung. Place tack coat and Petromat in accordance with the manufacturer's specifications. Overlay a minimum of 2 inches of AC. An additional alternative is to keep the existing pavement sections as is, but this will require a regular maintenance and repair program. Krazan&Associates,Inc.

With the addition of the aggregate base material, we recommend that a combined modulus of subgrade/base reaction value of 150 pounds per cubic inch be used in design where the rigid pavement is to be designed by a Structural Engineer. Rigid pavement design procedures have been developed by various agencies,including AASHTO and the Portland Cement Association (PCA).

A flexural strength of 550 psi should be specified accordingly. Our experience is that the compressive strength will have to be on the order of 3,800 to 4,500 psi may be required to achieve the required flexural strength. Prior to the construction of any rigid pavement, we recommend that concrete mix histories with flexural strength data be obtained from the proposed supplier. In the absence of flexural strength history, we recommend that laboratory trail batching and testing be performed to allow for confinnation that the proposed concrete mix is capable of producing the required flexural strength. The concrete pavements shall be designed with both longitudinal and transverse joints. The saw-cut or formed joints shall extend to a minimum depth on one-fourth of the pavement thickness plus '/a inch. Joint spacing shall not exceed 15 feet. Steel reinforcement of all rigid pavements is recommended to keep the joints tight and to control temperature cracking. Keyed joints are recommended at all construction joints to transfer loads across the joints. Joints should be reinforced with a minimtrrn of%z inch diameter by 48-inch long deformed reinforcing steel placed at mid-slab depth on 18-inch center-to-center spacing to keep the joints tight for load transfer. The joints shall be filled with a flexible sealer. Expansion joints shall be constructed only where the pavements abut structures or fixed objects. Smooth bar dowels, with a diameter of d/8, where d equals the thickness of the concrete, at least 14 inches in length, placed at a spacing of 12 inches on centers, may also be considered for construction joints to transfer loads across the joints. The dowels shall be centered across the joints with one side of the dowel lubricated to reduce the bond strength between the dowel and the concrete and fitted with a plastic cap to allow for bar expansion.

California Building Code has developed criteria for evaluation of sulfate and chloride levels and how they relate to cement reactivity with soil and/or water. The soil samples from the subject site were tested to have low sulfate and chloride concentrations. Therefore, normal concrete mixes may be used for concentrations such as found in these soils. Electrical resistivity testing of the soil indicates that the onsite soils may have a moderate potential for metal loss from electrochemical corrasion process.

LIMITATIONS 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 structure 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. Foundation and earthwork construction is characterized by the presence of a calculated risk that soil and groundwater conditions have been fully revealed by the original foundation investigation. This risk is derived from the practical necessity of basing interpretations and design conclusions on limited sampling of the earth. The recommendations made in this report are based on the assumption that soil conditions do not vary significantly from those disclosed during our field investigation. The logs of the exploratory borings do not provide a warranty as to the conditions that may exist beneath the entire site. The extent and nature of subsurface soil and groundwater variations may not become evident until construction begins. It is possible that variations in soil conditions and depth to groundwater could exist beyond the points of exploration that may require additional studies, consultation, and possible design revisions. If conditions are encountered in the field during construction, which differ from those described in this report, our firm should be contacted immediately to provide any necessary revisions to these recommendations. This report presents the results of our Geoteclmical Engineering Investigation, which was conducted for F the purpose of evaluating the soil conditions in terms of foundation and retaining wall design, and • grading and paving of the site.

The depths of exploration ranged from about 20 feet to 60 feet below the existing site surface. 4 additional shallow borings were excavated. Additionally 4 test pits were excavated and double ring htftltrometer tests were conducted per ASTM D3385 A member of our staff visually classified the soils in the field as the drilling progressed and recorded a continuous log of each boring. 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 soil and the boring logs are presented in this Appendix. During drilling operations, penetration tests were performed at regular intervals to evaluate the soil consistency and to obtain information regarding the engineering properties of the subsoils. Samples were obtained from the borings by driving either a 2.5-inch inside diameter Modified California tube sampler fitted with brass sleeves or a 2-inch outside diameter, 1-3/8-inch inside diameter Standard Penetration("split-spoon")test (SPT) sampler without sleeves. Soil samples were retained for possible laboratory testing. The samplers were driven up to a depth of 18 inches into the underlying soil using a 140-pound hammer falling 30 inches. The mmnber of blows required to drive the sampler was recorded • for each 6-inch penetration interval and the number of blows required to drive the sampler the last 12 inches are shown as blows per foot on the boring logs. The approximate locations of our borings and bulk samples are shown on the Site Plan,Figure 2. These approximate locations were estimated in the field based on pacing and measuring from the limits of existing site features. Laboratory Investigation The laboratory investigation was programmed to determine the physical and mechanical properties of the soil underlying the site. The laboratory-testing program was formulated with emphasis on the evaluation of in-situ moisture, density, gradation, shear strength, consolidation potential, expansion potential, maximum dry density, and R-value of the materials encountered. In addition, chemical tests were performed to evaluate the soil/cement reactivity and corrosivity. Test results were used in our engineering analysis with respect to site and building pad preparation through mass grading activities, foundation and retaining wall design recommendations, pavement section design, evaluation of the materials as possible fill materials and for possible exclusion of some soils from use at the structures as fill or backfill. Select laboratory test results are presented on the boring logs, with graphic or tabulated results of selected tests included in this Appendix. The laboratory test data,along with the field observations,was used to prepare the final boring logs presented in the Appendix. Krazaa&Associates,Inc.

SCOPE OF WORK: These specifications and applicable plans pertain to and include all earthwork associated with the site rough grading, including, but not limited to,the furnishing of all labor,tools and equipment necessary for site clearing and grubbing, stripping, preparation of foundation materials for receiving fill, excavation, processing, placement and compaction of fill and backfill materials to the lines and grades shown on the project grading plans and disposal of excess materials. PERFORMANCE: The Contractor shall be responsible for the satisfactory completion of all earthworks in accordance with the project plans and specifications. This work shall be inspected and tested by a representative of Krazan and Associates, Incorporated, hereinafter referred to as the Geotechnical Engineer and/or Testing Agency. Attainment of design grades, when achieved, shall be certified by the project Civil Engineer. Both the Geotechnical Engineer and the Civil Engineer are the Owner's representatives. If the Contractor should fall to meet the technical or design requirements • embodied in this document and on the applicable plans, he shall make the necessary adjustments until all work is deemed satisfactory as determined by both the Geotechnical Engineer and the Civil Engineer. No deviation from these specifications shall be made except upon written approval of the Geotechnical Engineer,Civil Engineer, or project Architect. No earthwork shall be performed without the physical presence or approval of the Geotechnical Engineer. The Contractor shall notify the Geotechnical Engineer at least 2 working days prior to the commencement of any aspect of the site earthwork. The Contractor agrees that he shall assume sole and complete responsibility for job site conditions during the course of construction of this project, including safety of all persons and property; that this requirement shall apply continuously and not be limited to normal working hours; and that the Contractor shall defend, indemnify and hold the Owner and the Engineers harmless from any and all liability, real or alleged, in connection with the performance of work on this project, except for liability arising from the sole negligence of the Owner or the Engineers. TECHNICAL REQUIREMENTS: All compacted materials shall be densified to the minimum relative compaction of 95 percent. Soil moisture content requirements presented in the Geotechnical Engineer's report shall also be complied with. The maximum laboratory compacted dry unit weight of each soil placed as fill shall be determined in accordance with ASTM test method D1557-00 (Modified Proctor). The optimum moisture content shall also be determined in accordance with this test method. The terms "relative compaction" and "compaction" are defined as the in-place dry density of the compacted soil divided by the laboratory compacted maximum dry density as determined by ASTM Test Method D1557-00, expressed as a percentage as specified in the technical portion of the Geotechnical Engineer's report. The location and frequency of field density tests shall be as determined Krazan&Associates,Inc. Offices Serving The western United States 12206026-final revised 091108 Appendix B Page B.2 by the Geotechnical Engineer. The results of these tests and compliance with these specifications shall be the basis upon which the Geotechnical Engineer will judge satisfactory completion of work. SOILS AND FOUNDATION CONDITIONS: The Contractor is presumed to have visited the site and to have familiarized himself with existing site conditions and the contents of the data presented in the Geotechnical Engineering Investigation report. The Contractor shall make his own interpretation of the data contained in the Geotechnical Engineering Investigation report and the Contractor shall not be relieved of liability under the Contract for any loss sustained as a result of any variance between conditions indicated by or deduced from said report and the actual conditions encountered during the progress of the work. DUST CONTROL: The work includes dust control as required for the alleviation or prevention of any dust nuisance on or about the site or the borrow area, or off-site if caused by the Contractor's operation either during the performance of the earthwork or resulting from the conditions in which the Contractor leaves the site. The Contractor shall assume all liability, including court costs of codefendants, for all claims related to dust or wind-blown materials attributable to his work. SITE PREPARATION Site preparation shall consist of site clearing and grubbing, over-excavation of the building pad areas, preparation of foundation materials for receiving fill, construction of engineered fill including the . placement of non-expansive fill where recommended by the Geotechnical Engineer, CLEARING AND GRUBBING: The Contractor shall accept the site in this present condition and shall demolish and/or remove from the area of designated project earthwork all structures, both surface and subsurface, trees, brush, roots, debris, organic matte- and all other matter determined by the Geotechnical Engineer to be deleterious. Site stripping to remove organic materials and organic-laden soils in landscaped areas shall extend to a minimum depth of 2 inches or until all organic-laden soil with organic matter in excess of 3 percent of the soils by volume are removed. Such materials shall become the property of the Contractor and shall be removed from the site. Tree root systems in proposed building areas should be removed to a minimum depth of 3 feet and to such an extent that would permit removal of all mots greater than 1 inch in diameter.

The StormVault system is designed to capture and hold floatable debris, free oils and greases, settleable sediments and those dissolved pollutants including metals, nitrates and phosphates, which may adsorb or adhere to the surface of sediments and organic debris in stormwater. In order to insure efficient operation and achieve the desired pollutant removal rates, several important inspection and maintenance functions must periodically be performed. The inspection and maintenance are both to be performed during dry periods, in which no flow is entering the StormVault system and water has returned to the permanent pool elevation. These procedures are described more fully below. Inspection The Storn-Vault is to be inspected bi-annually to ensure the system is in proper working order. The twice- yearly observation should require less than four person-hours per visit, but depends upon the size of the StormVault system. The inspection includes opening each manhole cover and visually inspecting for excess floating debris. The effluent chamber is to be inspected to verify that the control orifice within the standpipe is free of any trash or debris. In addition to the visual inspection, the first several chambers should be probed to gain an estimate of the collected sediment in the bottom of the vault. It is important to record the depths in these chambers to estimate when the next required maintenance should be performed. The removal of collected sediments is to be performed once the average depth in the vault reaches 6 inches. The hydrocarbon mats, which float on the surface of the StormVault system, are • designed to remove free oils and greases from stormwater runoff. One is placed in every third chamber, and the mats are attached to the manhole accesses using a lanyard. These mats must also be inspected as part of the bi-annual cycle. These mats will be a granular solid white when initially installed and will turn darker as they absorb free oils and greases. The mats should be inspected twice yearly to ensure that some white granular portions of the mat remain. The mats may collect some surface sediment; however, only when they change to a solid dark color uniformly throughout the granular medium do they need to be replaced. Maintenance The removal of collected sediments is to be performed once an average depth of 6 inches has been reached in the vault. The hydrocarbon sorbent mats are to be replaced once the mats turn completely dark in color and can no longer absorb any free oils and greases. The maintenance cycle for each StormVault unit will vary as it is a function of the size, type, and volume of pollutants in the stormwater runoff for that particular site. Previous monitoring and investigation of existing StormVault units has resulted in a recommended maintenance cycle of 4-5 years for both removal of sediment and replacement of hydrocarbon sorbent mats. A site-specific maintenance cycle can easily be determined by the bi-annual inspections. Removal of accumulated materials: It is recommended thai a professional pumping contractor, Trained and licensed to remove and dispose of captured sediment material, perform this task. The contractor will lower a nozzle and hose into each chamber and pump the collected material into a vacuum true[,.. The contractor is to remove only the 6 inches of sediment and not the water in the permanent pool during vacuuming. This will minimize the amount of material, which the contractor must dispose. ©2006 CONTECH Stormwater Solutions 1 • Be aware that the captured sediments are by their nature easy to resuspend. Great care shall be taken to prevent any turbulence that may cause mixing and resuspension of the settled materials. The contractor must verify proper disposal with the local jurisdiction. An analysis of the materials may be required before disposal. Because of dilution by the water in the permanent pool, harmful pollutant concentrations are rarely reached. Replacement of hydrocarbon sorbent mats: To remove the mats, locate the lanyard attached to the inside of the access cover and pull them out. Care should be taken in lifting the mats out through the manholes, as the saturated mats can weigh up to five times as much as new mats. The used mats should be disposed of as directed by the local authority. Generally this is in a similar manner used to dispose of drain oil or similar materials. Replace the mats in like fashion by clipping the new mats to the keeper lines. New mats can be obtained by contacting the CONTECH Stormwater Solutions office nearest you. NOTE: The StormVault by CONTECH Stormwater Solutions is a confined space and entry is not recommended. Enter only when necessary and with the proper equipment, following OSHA confined space entry procedures. • ©2006 CONTECH Stormwater Solutions 2 "�=ate',�,• riYY�F • f i hurfa. Filterra Piping Technical Details Filterra is supplied with an internal underdrain system that exits a wall in a perpendicular direction. Most efficient drainage is accomplished when the drain exits on the lower side of the Filterra® i.e. nearest the overflow bypass. This is more important when using the larger sized Filterrase).

Drawing DPI PRECAST FlLTERRA BOX BASE is a detail of the coupling. The coupling used is SDR-35 PVC. • Typically, a minimum slope of 0.50% is adequate to accommodate the flow of treated water from the Filterra, but each site may present unique conditions based on routing of the outfall pipe (elbows). The pipe must not be a restricting point for the successful operation of Filterran. All connecting pipes must accommodate freefall flow.

Filterra is similar in concept to bioretention in its function and applications, with the major distinction that Filterra has been optimized for high volume/flow treatment and high pollutant removal. It takes up little space (often 0.2% Filter Surface Area/Drainage Area) and may be used on highly developed sites such as landscaped areas, green space, parking lots and streetscapes. Filterra° is exceedingly adaptable and is the urban solution for Low Impact Development. Stormwater flows through a specially designed filter media mixture contained in a landscaped concrete container. The filter media captures and immobilizes pollutants; those pollutants are then decomposed, volatilized and incorporated into the biomass of the Filter-rag system's micro/macro fauna and flora. Stormwater runoff flows through the media and into an underdrain system at the bottom of the container, where the treated water is discharged.Higher flows bypass the Filterra via a downstream inlet structure, curb cut or other appropriate relief.

Do not place in a sump condition. The Filters cannot be used as a stand alone inlet— it will need effective bypass during higher intensity rainfall events. Plans MUST show Filterra® Top Curb (TC) and Flow Line (FL) spot elevations and also bypass TC (where applicable) and bypass FL spot elevations. The Filterra® TC and FL elevations MUST be higher than the bypass TC and FL elevations for effective bypass. Use Drawing FLP-2 (p.24) as a detail on the project plans. 2. For proper trash collection ensure a minimum 4" and maximum 6" Filterra® throat opening depth and use Drawing CGT-04 (p.25) as a detail on the project plans. 3. Do not direct surface flow to the Filterra in a "head-on" configuration. Refer to Guidelines GUl-A (p.12) and GU2 (p.13) for grading design that encourages flow to enter a Filterra` in a cross linear flow — left-to-right or right to-left in the gutter in front of the throat, as per a wet curb which prevents system damage. During extreme storm events the excess flow should continue past the Filterra' to a bypass inlet or other means of relief. Guideline GU3, Parking Lot Corners, shows common situations (p.14). 4. To calculate which size Filterra is required, use Table 1, Filterrag'' Quick Sizing Table, appropriate to the project's geographical region and target treatment regime (p.l]). The entire contributing drainage area to the Filterra should be considered and the minimum allowable C factors noted. The maximum contributing drainage area will vary with site conditions. For further information relating to sizing, please contact Filterra. 5. To ensure correct installation, include the Standard Filterra® Plan Notes (p.26-27) on your Filterra' detail project sheet, as well as detailed drawings FLP-2 and CGT-4 (p.24,25). 6. Positive drainage of each Filterra' unit's effluent treatment pipe is required to prevent free standing water from accumulating in the system or underdrain. This could occur due to tidal influences or improper connection ofFilterra's effluent pipe to a bypass structure or other outfall. 7.

Contact KriStar at (800) 579 8819 4/07 gip; �i�rr GENERAL SPECIFICATIONS FOR MAINTENANCE OF PLO-GARD+PLUS®CATCH BASIN INSERT FILTERS SCOPE: Federal, State and Local Clean Water Act regulations and those of insurance carriers require that stormwater filtration systems be maintained and serviced on a recurring basis. The intent of the regulations is to ensure that the systems, on a continuing basis, efficiently remove pollutants from stormwater runoff thereby preventing pollution of the nation's water resources. These specifications apply to the FloGard+Plus Catch Basin Insert Filter. RECOMMENDED FREQUENCY OF SERVICE: Drainage Protection Systems (DPS) recommends that installed Flo-Gard+Plus Catch Basin Insert Filters be serviced on a recurring basis. Ultimately, the frequency depends on the amount of runoff, pollutant loading and interference from debris (leaves, vegetation, cans, paper, etc.); however, it is recommended that each installation be serviced a minimum of three times per year, with a change of filter medium once per year.DPS technicians are available to do an on-site evaluation, upon request. RECOMMENDED TIMING OF SERVICE: UPS guidelines for the timing of service are as follows: 1. For areas with a definite rainy season: Prior to,during and following the rainy season. 2 For areas subject to year-round rainfall: On a recurring basis(at least three times per year). 3. For areas with winter snow and summer rain: Prior to and just after the snow season and during the summer rain season. 4. For installed devices not subject to the elements(washracks,parking garages,etc.): On a recurring basis(no less than three times per years). SERVICE PROCEDURES: 1. The catch basin grate shall be removed and set to one side. The catch basin shall be visually inspected for defects and possible illegal dumping. If illegal dumping has occurred, the proper authorities and property owner representative shall be notified as soon as practicable. 2. Using an industrial vacuum, the collected materials shall be removed from the liner. (Note: DPS uses a truck-mounted vacuum for servicing Flo-Gard+Plus catch basin inserts.) 3. When all of the collected materials have been removed, the filter medium pouches shall be removed by unsnapping the tether from the D-ring and set to one side. The filter liner, gaskets, stainless steel frame and mounting brackets, etc. shall be inspected for continued serviceability. Minor damage or defects found shall be corrected on-the-spot and a notation made on the Maintenance Record. More extensive deficiencies that affect the efficiency of the filter(torn liner, etc.), if approved by the customer representative, will be corrected and an invoice submitted to the representative along with the Maintenance Record. 4. The filter medium pouches shall be inspected for defects and continued serviceability and replaced as necessary and the pouch tethers re-attached to the liner's D-ring. See below. 5. The grate shall be replaced. • • REPLACEMENT AND DISPOSAL OF EXPOSED FILTER MEDIUM AND COLLECTED DEBRIS The frequency of filter medium pouch exchange will be in accordance with the existing DPS-Customer Maintenance Contract. DPS recommends that the medium be changed at least once per year. During the appropriate service, or if so determined by the service technician during a non-scheduled service, the filter medium pouches will be replaced with new pouches. Once the exposed pouches and debris have been removed, DPS has possession and must dispose of it in accordance with local, state and federal agency requirements. Note.-As the generator, the landowner a ultimately responsible for the proper disposal of the erposed filter medium and debris. Because the filter media likely contain petroleum hydrocarbons, heavy metals and other harmful pollutants, the materials nuat be treated as an EPA Class 2 Hazardous Waste and properly disposed of.DPS relieves the landowner of the actual disposal task,and provides certification of its completion in accordance with appropriate regulations. DPS also has the capability of servicing all manner of catch basin inserts and catch basins without inserts, underground oil/water separators,stormwater interceptors and other such devices. All DPS personnel are highly qualified technicians and are confined space trained and certified.

California Experience Infiltration basins have a long history of use in California, especially in the Central Valley. Basins located in Fresno were among those initially evaluated in the National Urban Runoff Program and were found to be effective at reducing the volume of runoff,while posing little long-term threat to groundwater quality(EPA, 1983; Schroeder, 1995). Proper siting of these devices is crucial as underscored by the experience of Caltrans in siting two basins in Southern California. The basin with marginal separation from groundwater and soil permeability failed immediately and could never be rehabilitated. Advantages ■ Provides l00% reduction in the load discharged to surface waters. eatitom�a Stormwater • ■ The principal benefit of infiltration basins is the nuatity approximation of pre-development hydrology during which a association January 2003 California Stormwater.BMP.Handbook 1 of 8 New Development and Redevelopment www.cabmphandbooks.com TC- 11 Infiltration Basin • significant portion of the average annual rainfall runoff is infiltrated and evaporated rather than flushed directly to creeks. ■ If the water quality volume is adequately sized, infiltration basins can be useful for providing control of channel forming (erosion) and high frequency (generally less than the 2-year) flood events. Limitations ■ May not be appropriate for industrial sites or locations where spills may occur. ■ infiltration basins require a minimum soil infiltration rate of o.5 inches/hour,.not appropriate at sites with Hydrologic Soil Types°C and D. ■ If infiltration rates exceed 2.4 inches/hour, then the runoff should be fully treated prior to infiltration to protect groundwater quality: ■ Not suitable on fill sites or steep slopes. ■ Risk of groundwater contamination in very coarse soils. ■ Upstream drainage area must be completely stabilized before construction. ■ Difficult to restore functioning of infiltration basins once clogged. Design and Sizing Guidelines •■ Water quality volume determined by local requirements or sized so that 85% of the annual runoff volume is captured. ■ Basin sized so that the entire water quality volume is infiltrated within 48 hours. ■ Vegetation establishment on the basin floor may help reduce the clogging rate. Construction/Inspection Considerations ■ Before construction begins,stabilize the entire area draining to the facility. If impossible, place a diversion berm around the perimeter of the infiltration site to prevent sediment entrance during construction or remove the top 2 inches of soil after the site is stabililized. Stabilize the entire contributing drainage area, including the side slopes, before allowing any runoff to enter once construction is complete. ■ Place excavated material such that it can not be washed back into the basin if a storm occurs during construction of the facility. ■ Build the basin without driving heavy equipment over the infiltration surface. Any equipment driven on the surface should have extra-wide (`low pressure") tires. Prior to any construction, rope off the infiltration area to stop entrance by unwanted equipment. ■ After final grading,till the infiltration surface deeply. ■ Useappropriate erosion control seed mix for the specific project and location. • 2 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www,cabmpha ndbooks.com Infiltration Basin TC- 11 • Performance As water migrates through porous soil and rock, pollutant attenuation mechanisms include precipitation, sorption, physical filtration, and bacterial degradation. If functioning properly, this approach is presumed to have high removal efficiencies for particulate pollutants and moderate removal of soluble pollutants. Actual pollutant removal in the subsurface would be expected to vary depending upon site-specific soil types. This technology eliminates discharge to surface waters except for the very largest storms; consequently, complete removal of all stormwater constituents can be assumed. There remain some concerns about the potential for groundwater contamination despite the findings of the NURP and Nightingale (1975; 1987a,b,c; 1989). For instance, a report by Pitt et al. (1994)highlighted the potential for groundwater contamination from intentional and unintentional storrawater infiltration.That report recommends that infiltration facilities not be sited in areas where high concentrations are present or where there is a potential for spills of toxic material. Conversely, Schroeder(1995) reported that there was no evidence of groundwater impacts from an infiltration basin serving a large industrial catchment in Fresno, CA. Siting Criteria The key element in siting infiltration basins is identifying sites with appropriate soil and hydrogeologic properties, which is critical for long term performance. In one study conducted in Prince George's County, Maryland (Galli, 1992), all of the infiltration basins investigated clogged • within 2 years. It is believed that these failures were for the most part due to allowing infiltration at sites with rates of less than o.5 in/hr, basing siting on soil type rather than field infiltration tests, and poor construction practices that resulted in soil compaction of the basin invert. A study of 23 infiltration basins in the Pacific Northwest showed better long-term performance in an area with highly permeable soils (Hilding, 1996). In this study, few of the infiltration basins had failed after 10 years. Consequently, the following guidelines for identifying appropriate soil and subsurface conditions should be rigorously adhered to. ■ Determine soil type (consider RCS soil type `A, B or C' only)from mapping and consult USDA soil survey tables to review other parameters such as the amount of silt and clay, presence of a restrictive layer or seasonal high water table, and estimated permeability. The soil should not have more than 30% clay or more than 40% of clay and silt combined. Eliminate sites that are clearly unsuitable for infiltration. ■ Groundwater separation should be at least 3 m from the basin invert to the measured ground water elevation. There is concern at the state and regional levels of the impact on groundwater quality from infiltrated runoff, especially when the separation between groundwater and the surface is small. ■ Location away from buildings, slopes and highway pavement(greater than 6 m) and wells and bridge structures (greater than 30 m). Sites constructed of fill,having a base flow or with a slope greater than 15% should not be considered. ■ Ensure that adequate head is available to operate flow splitter structures (to allow the basin • to be offline)without ponding in the splitter structure or creating backwater upstream of the splitter. January 2003 California Stormwater BMP Handbook 3 of 8 New Development and Redevelopment www.cabmphandbooks.com TC- 11 Infiltration Basin • ■ Base flow should not be present in the tributary watershed. Secondary Screening Based on Site Geotechnical Investigation ■ At least three in-hole conductivity tests shall be performed using USBR 7300-89 or Bouwer- Rice procedures (the latter if groundwater is encountered within the boring), two tests at different locations within the proposed basin and the third down gradient by no more than approximately io m. The tests shall measure permeability in the side slopes and the bed within a depth of 3 m of the invert. ■ The minimum acceptable hydraulic conductivity as measured in any of the three required test holes is 13 mm/hr. If any test hole shows less than the minimum value, the site should be disqualified from further consideration. ■. Exclude from consideration sites constructed in fill or partially in fill unless no silts or clays are present in the soil boring. Fill tends to be compacted,with clays in a dispersed rather than flocculated state, greatly reducing permeability. ■ The geotechnical investigation should be such that a good understanding is gained as to how the stormwater runoff will move in the soil (horizontally or vertically) and if there are any geological conditions that could inhibit the movement of water. Additional Design Guidelines (i) Basin Sizing -The required water quality volume is determined by local regulations • or sufficient to capture 85% of the annual runoff. (2) Provide pretreatment if sediment loading is a maintenance concern for the basin. (3) Include energy dissipation in the inlet design for the basins. Avoid designs that include a permanent pool to reduce opportunity for standing water and associated vector problems. (4) Basin invert area should be determined by the equation: A = WOV kt where A= Basin invert area (m2) WQV =water quality volume (m3) k= 0.5 times the lowest field-measured hydraulic conductivity (m/hr) t = drawdown time (48 hr) (5) The use of vertical piping, either for distribution or infiltration enhancement shall • not be allowed to avoid device classification as a Class V injection well per 40 CFR146.5(e)(4)• 4 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Infiltration Basin TC- 11 • Maintenance Regular maintenance is critical to the successful operation of infiltration basins. Recommended operation and maintenance guidelines include: ■ Inspections and maintenance to ensure. ■ Observe drain time for the design storm after completion or modification of the facility to confirm that the desired drain time has been obtained. ■ Schedule semiannual inspections for beginning and end of the wet season to identify potential problems such as erosion of the basin side slopes and invert, standing water,trash and debris, and sediment accumulation. ■ Remove accumulated trash and debris in the basin at the start and end of the wet season. ■ Inspect for standing water at the end of the wet season. ■ Trim vegetation at the.beginning and end of the wet season to prevent establishment of woody vegetation and for aesthetic and vector reasons. ■ Remove.accumulated sediment and regrade when the accumulated sediment volume exceeds io% of the basin. ■. If erosion is occurring within the basin,revegetate immediately and stabilize with an erosion • control mulch or mat until vegetation cover is established. . ■ To avoid:reversing-soil development, scarification or other disturbance should only be performed.when there are,actual signs of clogging, rather than on a routine basis. Always remove deposited sediments before scarification, and use a hand-guided rotary tiller, if possible, or a disc harrow pulled by a very light tractor. Cost Infiltration basins are relatively cost-effective practices because little infrastructure is needed when constructing them. One study estimated"the total construction cost at about $2 per ft (adjusted for inflation) of storage for a 0.25-acre basin (SWRPC, 1991). As with other BMPs, these published cost estimates may deviate greatly from what might be incurred at a specific site. For instance, Caltrans spent about $18/ft3 for the two infiltration basins constructed in southern California, each of which had a water quality volume of about 0.34 ac.-ft. Much of the higher cost can be attributed to changes in the storm drain system necessary to route the runoff to the basin locations. Infiltration basins typically consume about 2 to 3% of the site draining to them,which is relatively small.Additional space may be required for buffer, landscaping, access road, and fencing. Maintenance costs are estimated at 5 to 10%of construction costs. One cost concern associated with infiltration practices is the maintenance burden and longevity. If improperly maintained, infiltration basins have a high failure rate. Thus, it may be necessary to replace the basin with a different technology after a relatively short period of time. • January 2003 California stormwater BMP Handbook 5 of 8 New Development and Redevelopment www,cabmphandbooks.com TC- 11 Infiltration Basin •References and Sources of Additional Information Caltrans, 2002, BMP Retrofit Pilot Program Proposed Final Report, Rpt.

The subject site is currently occupied by a Wal-Mart store. Refer to Figure No. 2, Site Map, for locations of the following referenced on-site features: • An approximately 149,500 square-foot concrete tilt-up retail building constructed on a concrete slab-on-grade foundation is located on the southern portion of the subject site. An Express Lube auto service center is attached to the building on the southwest side. An asphalt parking lot of approximately 1016 spaces is located in the central portion of the property. • Two ASTs were observed in the Express Lube auto service center. One AST is used for virgin • motor oil and the other for used motor oil. No evidence of staining or leakage was observed on the paved ground surface beneath or adjacent to the ASTs. • No evidence of staining, cracks or floor drains was observed on the Portland cement concrete (PCC)foundation beneath or adjacent to the AST/containers. • An in-ground grease trap was observed along the east side of the building located on the subject site.No staining or foul odors were observed around the manhole. • No evidence of hazardous materials storage/waste was observed within, in proximity to or adjacent to the building/structure AST etc. or De minimis staining was observed on the paved/unpaved ground surface adjacent to or beneath the referenced containers. • During the visual observations of the subject site, retail quantities of cleaners, adhesives, lubricants, and paints were being displayed on store shelves for sale.No staining of the floors was observed inside of the building. • Exposed suriace soils did not exhibit obvious signs of discoloration. No obvious evidence (vent pipes, rill pipes; dispensers- etc.) of USTs were noted within the areas observed. No standing water or major depressions were observed on the subject site. No indications of former structures, such as foundations, were observed on the subject site. • During Krazan's January 12, 2007 site reconnaissance, one pad-mounted electrical transformer was observed on the subiect site. The transformer casing displayed no visual evidence of leakage and the ground surface below the transformer. Based on the visual absence of apparent • unauthorized releases of insulating fluids from the on-site transformers at the time of Krazan's site reconnaissance, the on-site transformer is not currently anticipated to pose an adverse impact to the subject site. However, in the event of a future release/leak of insulating fluids from the on- site transformer,.

The Seven Eleven Gas Station located adjacent to the east of the subject site. Refer to Section 6.3 of this report titled • Regulatory Agency Interface for a discussion of regulatory records for the Seven Eleven Gas Station facility. 4.3 Asbestos-Containing Building Materials The structure located on the subject site was constructed in approximately 2005. It is unknown if the on- site structure contain asbestos-containing building materials(ACBMs). An asbestos survey and sampling of the on-site structure was not included within the scope of this assessment During Krazan's December 8, 2006 site reconnaissance, no damaged building materials which appeared to be posing a health hazard were noted in the on-site structure. Prior to conducting any repair, renovation, or demolition work, an asbestos survey should be conducted. t Z Lead-Based Pain; During Krazan's December 9. 2006 site reconnaissance, interior and exterior paint appeared in good conditions with no evidence of peeling or damage-Request dates of last painting from on-site managers However. it is unknown if the on-site structures contain lead-based paint. A lead-based paint survey was not conducted within the scope of this assessment. 4.6 Potable Water Source The water purveyor for the subject site is the Eastern Municipal Water District (EMWD). The EMWD's water quality monitoring is an on-going program with water samples obtained on a regular basis. It is the KRAZAN &ASSOCIATES. INC. With Ofjtces Serving the Western United States - 121 06014 AAI Prase Ion: Project No. 124-06014 • Page No. 6 responsibility of the EMWD to provide customers with potable water to compliance with the California State Maximum Contaminant Levels(MCLS)for primary drinking water constituents in water supplied to the public. 4.7 Sewage Disposal System On December 5, the EMWD was contacted regarding sewer service for the subject site. According to a representative of the EMWD, sewer service has been provided to the subject site by the EMWD since 2005. According to EMWD records,no sewer violations are on file for the subject site. 5.0 USER-PROVIDED INFORMATION A review of user-provided title reports and a completed Phase I ESA user questionnaire was conducted in order to help identify pertinent information regarding potential environmental impacts associated with the subject site. • 5.1 Title Report On February 21, 2007,a Preliminary Title Report(PTR)for the subject site by Stewart Title of California was provided to Krazan by Garry Brown with Gresham Svage Nolan & Tilden. The subject site PTR was reviewed to identify potential deed restrictions, environmental liens or activity and use limitations (AULs) which may have occurred on or exist in connection with the subject site as indicated by the subject site PR. Krazan's review of the PTR indicated no deed restrictions, environmental liens or AULs for the subject site. However, as quoted from the subject site PTR "it is important to note that this Preliminary Report is not a written representation as to the condition of title and may not list all liens, defects and encumbrances affecting title to the land." The absence of a condition of title represents a data gap. Therefore,Krazan recommends that at the close of the real estate transaction and upon the issuance of the final Title Report(TR)that the final TR be reviewed and any information deviating from that presented in the PTR reviewed herein resealing evidence of RECc,be evaluated and documented in coniunction with . this report. Please refer to Appendix A for a copy of the PTR. 5.2 Phase I Environmental Site Assessment User Questionnaire On March 2. 2007 a completed Phase I ESA user questionnaire was received from W. Kelly Collier. Please refer to Appendix C for a copy of the completed user questionnaire. • In order to quality for one of the Landowner Liability Protections (LLPs) offered by the Small Business Liability Relief and Brownfields Revitalization Act of 2001 (the `Browrzfields Amendments"), the user KRAZAN & ASSOCIATES.INC.

Commonly known or reasonably ascertainable information about the property. 6. The degree of obviousness of the presence or likely presence of contamination at the properny and the ability to detect the contamination by appropriate investigation. According to the questionnaire responses, Mr. Collier, to the best of his knowledge as the user of this Phase I ESA,was not aware of any environmental cleanup liens and activity or land use limitations which • have been filed or recorded against the subject site; and Mr. Collier has no specialized knowledge or experience of the prior nature of the business or chemical utilization on the subject site. Mr.Collier stated that he is not aware of past uses for the subject site however; Mr. Collier indicated that he did not have knowledge of the past or current presence of specific chemicals or hazardous materials, unauthorized spills or chemical releases or of any environmental cleanup liens in connection with the subject site. Additionally, Mr. Collier stated that the purchase price of the subject site reasonably reflects fair market value. 6.0 SITE USAGE SURVEY The oronem; usage survey included assessing oroperh° piston-. and revicwinL local- state. and fedaral rewtatory agency records. 6.1 Site History A review of historical aerial photographs, reasonably ascertainable Haines Criss-Cross Directories (11CCDs) and Polk Guide Directories (PGDs), Sanborn Fire Insurance Maps (SFIMs), and Phase I ESA interview • were conducted with the past and present owner to assess the history of the subject site. Aerial Photograph Interpretation KRAZAN S ASSOCIATES,INC. With Offices Seming the If-esterr- United States 124-06014 AAi Pius-I am Project No. 124-06014 • Page No. 8 Historical aerial photographs dated 1938, 1946, 1953, 1967, 1980, 1989, 1994, and 2002 were reviewed to assess the history of the subject site. These photographs were obtained from the Environmental Data Resources, Inc., (FDR). Aerial photograph coverage for the years prior to 1938 (for properties with development in 1937 or no coverage prior to 1937) and between 1967 and 1980 was not reasonably ascertainable or available. The aerial photograph summary is provided below in Table IV. TABLE IV Summary of Aerial Photograph Review Year/Scale Site Use Site and Adjacent Property Observation 1938 Agriculture The subject site appears to be utilized for agricultural purposes with 1"= 555' no visible on-site structure or dwellings. Adjacent properties appear to be utilized for agricultural purposes to the north, west and east with undeveloped land to the south. 1946 Agriculture Conditions on the subject site and the adjacent properties appear 1" = 655' relatively similar to those noted in the 1938 aerial photograph. 1953 Agriculture Conditions on the subject site and the adjacent properties appear I"= 555' relatively similar to those noted in the 1946 aerial photograph. 1967 Agriculture Conditions on the subject site and the adjacent properties appear I"= 555' relatively similar to those noted in the 1953 aerial photograph. 1980 Agriculture Conditions on the subject site and the adjacent properties appear I" =600' relatively similar to those noted in the 1967 aerial photograph. • 1989 Agriculture Conditions on the subject site and the adjacent properties appear 1" =666' relatively similar to those noted in the 1980 aerial photograph. 1994 Vacant The subject site and the adjacent properties appear to be vacant with 1"= 1,350' earthwork being conducted_ Increased residential and commercial development is visible in the subject site vicinity. 2002 Vacant Conditions on the subject site and the adjacent properties appear 1" =666' relatively similar to those noted in the]994 aerial photograph with the exception of a road has been cut through the subject site. Increased residential and commercial development is visible in the subject site vicinity City of Temecula Building Department On December 14,2006 a building permit records request was submitted to the City of Temecula Building Deparnnent (CTBD) for the subject site address of 32225 US Highwa., 79 South. Accordina to z representative of the CTBD, numerous building permit records are on file with the CTBD for the subject site. However, no permits for items such as underground storage tanks, septic sysiems, building, demolition, or previous structures/features are on fiie with the CTBD for the subject site. Haines Criss-Cross and Polk Guide Directories • HCCDs and PGDs dated 1970 through 2006 were provided by EDF: for the subject site address. Wal- Mart was listed for 2005.No additional businesses were Iisted at the subject site prior to 2005. KRAZAN &ASSOCIATES,INC. il''ith Offices Serving the ff emerr United Srates 124-0014 Ani r=,-IA.- Project No. 124-06014 • Page No. 9 Sanborn Fire Insurance Maps Krazan reviews SFIMs to evaluate prior land use of the subject site and the adjacent properties. SFIMs typically exist for cities with populations of 2,000 or more, the coverage dependent on the location of the subject site within the city limits. On December 4, 2006,Krazan contracted with EDR to provide copies of available SFIMs for the subject site and the adjacent properties as far back as 1867. EDR's search of SFIMs revealed no coverage for the subject site and the adjacent properties. Refer to Appendix B for a copy of the EDR SFIM No Coverage Letter. Phase I Environmental Site Assessment Interview On January 11, 2007 a Phase I ESA interview was conducted with Kim Kutchfar of Wal-Mart Inc., a store manager for the subject site. The interview is designed to provide pertinent information regarding potential environmental impacts associated with the subject site. According to Ms. Kutchfar,to the best of her knowledge, no on-site treatment and/or discharge of waste; • no on-site leach fields, dry wells, sumps, or disposal ponds; no use, storage, or disposal of hazardous materials with the exception of motor oil and antifreeze from the Express Lube department,no existing or former USTs; no hazardous materials spills; no buried materials; no monitoring, domestic, or irrigation wells subject site. Ms. Kutchfar stated that there are ASTs located in the Express Lube department used to store motor oil. Phase I Environmental Site Assessment Interview-Previous Owner A Phase I ESA interview with the previous owner of the subject site was not reasonable ascertainable. Consequently, information regarding the history and historical uses of the subject site obtained from interview of a previous owner constitutes a data gap. 6.2 Agricultural Chemicals Review or historical aerial photographs indicates the subject site was utilized for agricultural purposes from at least 1938 to 1989. Agricultural chemicals are not usually applied to hay or pasture land. Agricultural chemicals in use today are applied in dilute concentrations and, when used properly, degrade relatively quickly. However, environmentally persistent pesticides can linger in the soil for many years. • 11 is not known if environmentally persistent pesticides have been applied to the subject site in the past. However, generally, sampling and analysis of surface soils from properties with similar agricultural histories has typically yielded non-detectable results for analysis of environmentally persistent pesticides. K'RAZAN&ASSOCIATES. INC. With Offices Serving the Western United States 124-06014 AAT Ph_-Ld.r Project No. 124-06014 Page No. 10 Therefore, the potential for elevated concentrations of environmentally persistent pesticides to exist in the near-surface soils of the subject site, which would require regulatory action, is low. 63 Regulatory Agency Interface A review of regulatory agency records was conducted to help determine if hazardous materials have been handled, stored, or generated on the subject site and/or the adjacent properties and businesses. Regulatory records are reviewed based on the following criteria: I) properties with known groundwater contamination that are located within 500 feet of the subject site; 2) properties that are adjacent or in proximity to the subject site included within the EDR report or noted during the site reconnaissance to possibly handle, store,or generate hazardous materials.Applicable property records are discussed below. Riverside County Department of Environmental Health On December 4,2006,the Riverside County Department of Environmental Health (RCEH)was contacted regarding potential records associated with USTs, leaking underground storage tanks(LUSTS),hazardous • materials business plans (HMBPs) for the subject site and area properties of environmental concern. According to a representative of the RCEHD, the following records of USTsfHMBPs/LUST are on file for the subject site: Wal-Mart Store 42708 subject site 32225 Highway 79 South According to the RCEHD, a HMBP is on file for the subject site. A HMBP is required when a facility exceeds a specified quantity of hazardous materials/waste. The subject site meet the required reporting limits for the following materials: motor oil, used motor oil, used oil filters, car batteries, windshield washer fluid, carbon dioxide, helium, and propane. These materials are not anticipated to pose an adverse impact to the subject site due to the absence of documented releases of hazardous materials to the subsurface on file with the RCDEH. Wal-Mart Store»270R subiect site 32225 Hiahway 79 Souti, According to the RCEHD,. a hazardous materials spill was reported at the subject site on April 10. 2006. A vehicle in the narking lot was discovered to be leakin_ gasoline. Approximately R oalions spilled onto the asphalt. A California Department of Forestry (CDF) fire engine responded to the spill. The CDF crew used absorbent to contain the spilled fuel. The gasoline did not enter any storm drains and was contained on the asphalt.

In general, only potentially hazardous materials released from facilities located approximately hydraulically up-gradient and within a few hundred feet of the site, or in a hydraulically cross-gradient direction close to the site, are judged to have a reasonable potential of migrating to the site. This opinion is based on the assumption that materials generally do not migrate large distances laterally within the soil, but rather tend to migrate with groundwater in the general direction of groundwater flow. The remaining properties within the specified search radius of the subject site which appeared on local, state, or federally published lists of sites that use or have had releases of hazardous materials are of sufficient distance and/or situated hydraulically cross- or down-gradient from the subject site such that impact to the subject site is not likely. • Seventeen orphan sites were identified in the EDR-provided government database report Based upon Krazan's visual observations made during our site reconnaissance, as well as various influencing factors including approximate distance from the subject site,the orphan sites are deemed to have low potential to impact the subject site. No engineering control sites, sites with institutional controls, or sites with deed restrictions were listed for the subject site,adjacent sites or vicinity properties in the EDR-provided government database report. No Indian reservations or leaking USTs (LUSTs) on Indian land were reported on the subject site, adjacent sites or vicinity properties in the EDR-provided government database report. 7.0 DISCIISSION OF FINDINGS Historical Uses: The subject site consists of a 13.4_-acre rectangular-shaped parcel of land located on the south side of US Highway 79 South and west of Apis Road in Temecula. California. Krazan's review of historical aerial photographs, HCCDs, CTBD records, and SFIMs indicates that the subject site was utilized primarily for • agricultural purposes since 1938. The current retail shopping center was constructed in 2004. Based on Krazan's review of historical aerial photographs, a site reconnaissance, and contacts with the local KRAZAN&ASSOCIATES,INC. With Offices Serving the Western United States Ila 060i4 AU roan Loo, Project No. 124-06014 • Page No. 15 regulatory agencies and the owner of the subject site, the potential for recognized environmental conditions to exist in connection with the historical uses of the subject site appears to be low. Current Uses: At the time of Krazan's site reconnaissance, the subject site was observed to be occupied by a 149,551 square-foot retail store on a concrete slab-on-grade foundation located at 32225 US Highway 79 South in Temecula, California. The subject building was constructed in 2004. The subject site includes asphalt paved parking areas and an unpaved area just east of the subject building. At the time of Krazan's site reconnaissance the subject site store was occupied by Wal-Mart. contacts with local regulatory agencies, and an interview with the owner of the subject site, the potential for recognized environmental conditions to exist in connection with the current uses of the subject site appears to be low. Adjacent Properties: Based on Krazan's field observations, review of the EDR Radius Map report, and consultation with local regulatory agencies,the potential for recognized environmental conditions to exist in connection with the subject site from adjacent property uses appears to be low. • However, due to its proximity to the subject site,the eastern adjacent Seven Eleven Gasoline Station has the potential to present a recognized environmental condition in connection with the subject site in the event of a significant unauthorized release of fuel from the Seven Eleven Gasoline Station underground fuel system. Based on Krazan's review of regulatory records, the Seven Eleven Gasoline Station underground fuel system is not currently anticipated to present a recognized environmental condition in connection with the subject site due to absence of documented unauthorized releases of fuel on file with the RCDEH, the lead regulatory agency for underground storage tank facilities in Riverside County. In the event of a significant unauthorized release of fuel at the Seven Eleven Gasoline Station, potential subsurface assessments or remediation associated with an.underground fuel release would be the responsibility of the Seven Eleven Gasoline Station propetiv owners.. 7.1 ?;valuation of Data Gaps/Data Failure In accordance with ASTM E 1527-05 guidance; data gaps represent a lack of or inability to obtain information required by this practice despite good faith efforts by the environmental professional to • gather such information. Data gaps may, result from incompleteness in any of the activities required by this practice. Data failure represents the failure to achieve the historical research objectives of this practice even after reviewing the standard historical sources that are reasonably ascertainable and likely to KI:AZAN S ASSOCIATE&.INC. With Of Serving tine If earern United Siaim 124-06014 P.AI Pnau Ltioc Project No. 124-06014 Page No. 16 be useful. Data failure is one type of data gap. The following is a summary of data gaps encountered in the process of preparing this report including an observation as to the presumed significance of that data gap to the conclusions of this assessment. • Absence of Final Title Report • Absence of Interview with Previous Property Owner However, taken in consideration with the available information obtained in the course of preparing this report in conjunction with professional experience, there is no evidence to suggest that these data gaps might alter the conclusions of this assessment. 8.0 CONCLUSIONS/OPINIONS We have conducted a Phase I ESA of the subject site in conformance with the scope and limitations of the ASTM El 527-05 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. Any deviations from this practice were previously described in this report. This • assessment has revealed no evidence of recognized environmental conditions in connection with the subject site. 9.0 LIMITATIONS The site reconnaissance and research of the subject site has been limited in scope. This type of assessment is undertaken with the calculated risk that the presence, full nature, and extent of contamination would not be revealed by visual observation alone. Although a thorough site reconnaissance was conducted in accordance with ASTM Guidelines and employing a professional standard of care, no warranty is given, either expressed or implied, that hazardous material contamination or buried structures, which would not have been disclosed through this investigation, do not exist at the subject site. Therefore_the data obtained are clear anti accurate oniy to fine, degree implied by the sources and methods used. The findings presented in this report were based upon field observations during a singie property visit, review of available data. and discussions with local regulatory and advisory agencies. Observations describe only the conditions present at the time of this investigation. The data reviewed and observations • made are limited to accessible areas and currently available records searched_ Krazan cannot guarantee the compieteness or accuracy of the regulatory agency records reviewed. Additionally, in evaluating the property. Krazan has relied in good faith upon representations and information provided by individuals KRAZAN$ASSOCIATES, INC. With Offices Serving the Western united States 124-06014`A1 Prase Ldoe Project No. 124-06014 • Page No. 17 noted in the report with respect to present operations and existing property conditions, and the historical uses of the property. It must also be understood that changing circumstances in the property usage, proposed property usage, subject site zoning and changes in the environmental status of the other nearby properties can alter the validity of conclusions and information contained in this report. Therefore, the data obtained are clear and accurate only to the degree implied by the sources and methods used. This report is provided for the exclusive use of the client noted on the cover page and shall be subject to the terms and conditions in the applicable contract between the client and Krazan. Any third party use of this report, including use by Client's lender, shall also be subject to the terms and conditions governing the work in the contract between the client and Krazan. The unauthorized use of, reliance on, or release of the information contained in this report without the express written consent of Krazan is strictly prohibited and will be without risk or liability to Krazan. Conclusions and recommendations contained in this report are based on the evaluation of information made available during the course of this assessment. It is not warranted that such data cannot be superseded by future environmental, legal, geotechnical or technical developments. Consequently, given • the possibility for unanticipated hazardous conditions to exist on a subject site which may not have been discovered, this Phase I ESA is not intended as the basis for a buyer or developer of real property to waive their rights of recovery based upon environmental unknowns. Parties that choose to waive rights of recovery prior to site development do so at their own risk. • KRAZAN&ASSOCIATES, INC. _ With Offices Serving the Western United States 124-06014 AAT Ph.,t Ldoc Project No. 124-06014 • Page No. 18 10.0 OUALWICATIONS This Phase I ESA was conducted under the supervision or responsible charge of Krazan's undersigned environmental professional with oversight from the undersigned registered engineer.
