Pollutants of Concern 11 Water Quality Management Plan (WQMP) Chaparral Village Center 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.htm]. 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: See Following Page 06/15/07, 08/07/07, 02/04/08, 03/27/08 CJ • n LJ Water Quality management Plan (WQMP) Chaparral Village Attachment to Section III Item #1. Addressed in Section II, Receiving Waters Table. Item 42. Addressed in Section II, 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. POLLUTANTS POTENTIAL SOURCE 303 (d) LISTING Expected Potential Sediment Erosion N/A Nutrients Fertilizer Murrieta Creek Organic Compounds None N/A Trash & Debris Vehicles and Site Activities N/A Oxygen Demanding Substances Fertilizer Murrieta Creek and Santa Margarita River Bacteria/Viruses None N/A Oils and Grease Vehicles N/A Pesticides e N/A Metals TM22--ieta Creek 902.32 and 902.52 Pollutant of Concern: Murrieta Creek is listed on the 2006 Clean Water Act Section 303(d) List of Water Quality limited Segments as being impaired by Phosphorus, Nitrogen, Iron and Manganese. As such, these pollutants of Concern for this project. Legacy Pollutants: According to PSA dated March 22, 2006 by LGC Inland (Appendix H). The project property was formerly maintained as pasture land from 1949-1980 at some point it was graded to its present condition but never developed before. It appears unlikely that any legacy pollutants have been introduces to this site. No on-site pollutants were found and no historical evidence was found. Water Quality Management Plan (WQMP) Chaparral Village Center 0 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 I 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.

The location of each Site Design BMP must also be shown on the WQMP Site Plan included in Appendix B. Design concepts incorporated into the project plans include incorporation landscape buffer areas between sidewalks and streets to minimize urban runoff. The project plan also tries to maximize the permeable area of the site by adding as much landscape area to the perimetrer of the project as possible. By minimizing directly connected impervious areas, the site drains impervious sidewalks and walkways into the adjacent landscaping. All water from the site will also pass through the grass Swale prior to entering the storm drain system. 6/15/07, 8/07/07, 02/04/08, 03/27/08, 03/31/08 0 Non -applicable site Design BMPs: • u Water Quality management Plan (WQMP) Chaparral Village 1) Minimize Urban Runoff a.

Drainage design has been done in accordance with the Riverside County Flood Control and Water Conservation District Hydrology Manual (Reference 1) and the Riverside County Water Quality Management Plan for Urban Runoff, Santa Ana River Region and Santa Margarita River Region (Reference 2). However, as per the City of Temecula, no detention for the site is being required. Therefore, this study details historic flows, developed flows, water quality measures, and methodology used in the analysis. Figures and schematics are included to illustrate key points, along with a compilation of design data and calculations. GENERAL LOCATION AND DESCRIPTION Chaparrel Village is located in Section 25, Township 7 South, Range 3 West in the City of Temecula, California. More particularly, the Chaparrel Village site is 4.375 acres in size, and is made up of parcels 5-8 of Parcel Map 26232-2. The site is bounded to the north by Nicolas • Road, to the south by an existing subdivision, to the west by an Arco Gas Station and Jack in the Box Restaurant, and to the east by an existing Daycare Center (refer to Appendix A for the Vicinity Map and Aerial Exhibit). The site is located within the Santa Margarita watershed, and lies in FEMA Flood Zone D, an area where flood hazards are undetermined (refer to Appendix A for the Watershed Exhibit and FEMA FIRM Map). Existing topography on the site is generally flat, and drains towards an existing storm inlet and catch basin located in the northwest corner of the site. The hydraulic soils group for the site is type `B" (Refer to Appendix A for the Hydrologic Soils Map for Murrieta and USDA Soils Map). METHODOLOGIES This drainage study was prepared in accordance with the Riverside County Flood Control and Water Conservation District Hydrology Manual (Reference 1) and the Riverside County Water Quality Management Plan for the Santa Ana River Region and Santa Margarita River Region (Reference 2). Per these references, the 10 -year recurrence event was analyzed for the minor storm, while the 100 -year recurrence event was analyzed for the major storm. Also, the CivilDesign® software was used to calculate runoff flows and is based on the following l.1 equation: CONCEPTUAL DRAINAGE STUDY L Rational Method Formula: Q=CIA (f • Where: Q = Peak discharge (cfs) C = Coefficient of runoff I = Rainfall intensity (inches/hour) corresponding to the time of concentration A = Area (acres) Rainfall intensity data was taken from the Murrieta-Temucula & Rancho California Intensity - Duration Curve Data (see Appendix A for Standard Intensity — Duration Curves Data). HISTORIC HYDROLOGY Historically, the Chaparrel Village development has been rough graded per Parcel Map 26232-2 to drain as one basin towards the northwest corner of the site. Additional offsite flows from the south are also draining onto and through the Chaparrel Village development. These basins are being labeled as Historic Basin Hl and Offsite Basin 0S -H1 for the purposes of this report (Refer to Chaparrel Village Historic Drainage Exhibit located in Appendix B for an overall depiction of historic drainage patterns). All flows draining onto the site are being collected by an existing storm inlet and catch basin, which are then piped offsite by means of a 24" storm pipe. The existing 24" storm pipe has been analyzed using as -built plans from Parcel Map 26232-2 and CivilDesign® Water Surface Pressure Gradient t Analysis Program, which determined that the flowing full capacity is 23 cfs (Refer to f Appendix B for Parcel Map 26232-2 Rough Grading Plan and WSPGW printouts). Below is a chart summarizing all historic 10 -year and 100 -year flows (Refer to Appendix B for Rational Method Calculations): HISTORIC FLOWS HISTORIC DESIGN ACREAGE Q2 (cfs) Q10 (cfs) Q100 (cfs) BASIN POINT (ACRES) H1 1.0 4.38 3.69 6.00 939 OS -Hl 2.0 2.08 3.11 4.92 7.55 DEVELOPED HYDROLOGY The Chaparrel Village development has been graded to drain as one basin, Basin D1. This basin drains towards the northern end of the site, where a grass Swale collects all onsite flows, directing them to the northwest corner of the site. This grass swale will be designed at time of final lengineering to handle the 100 -year flows. From there onsite flows will be captured by a proposed catch basin, which ties into an existing 24" storm pipe. As stated above, the existing CONCEPTUAL DRAINAGE STUDY 2 24" storm line is sized to handle roughly 23 cfs, which is more than sufficient to handle the 13.67 �• cfs of runoff generated from the site. Also, an offsite basin, OS -D1, will be captured along the southern property line in a concrete pan, and diverted around the site. The offsite flows will be discharged into the access drive bordering the west of the property and travel north until they flow into the existing curb and gutter of Nicolas Road. Below is a chart summarizing all developed 10 -year and 100 -year flows (Refer to Appendix C for Rational Method Calculations): DEVELOPED FLOWS DEVELOPED DESIGN ACREAGE Q2 (cfs) Q10 (cfs) Q100 (cfs) BASIN POINT (ACRES) D1 1.0 4.38 6.06 9.18 13.67 OS -D1 2.0 2.08 2.02 3.27 5.08 WATER QUALITY MEASURES To address the water quality concerns, Best Management Practices were selected using the j • criteria described in the Riverside County Drainage Area Management Plan (DAMP) (Reference 2). The potential pollutants listed in Table 2 of the DAMP for commercial land use include metals, nutrients, pesticides, organic compounds, sediments, trash & debris, oxygen demanding substances, and oil & grease. Using Table 3, the Treatment Control BMP Selection Matrix, grass swales were chosen to address these pollutants (Refer to Appendix D for Water Quality Design Worksheets). Also, for further information see Water Quality Management Plan. CONCLUSIONS Drainage flows from the Chaparrel Village site follow historic patterns. Storm water is carried through the site via concrete pans, curb and gutter, and grass -lined swales. The overall drainage concept is to convey onsite flows through the site, achieving the required water quality before discharging from the site{ Drainage design has been done in accordance with Riverside County Flood Control and Water Conservation District Hydrology Manual (Reference 1) and the Riverside County Water Quality Management Plan for the Santa Ana River Region and Santa Margarita River Region (Reference 2) regulations. Refer to the Appendix sections of this report for all relevant calculations and reference material. CONCEPTUAL DRAINAGE STUDY 3 (9 (-0 REFERENCES 1.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from • long -duration stomrs. (� The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and CID). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet_ These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high mnoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very stow rate of water transmission. If a soil is assigned to a dual hydrologic group (AID, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. - Parameter Summary L Hydrologic Soil Group Aggregation Method: Dominant Condition Component Percent Cutoff.

The storm drain system is designed to help prevent flooding by carrying excess rainwater away from streets. Since the storm drain system does not provide for water treatment, it also serves the unintendedfunction of transporting pollutants directly to our waterways. Unlike sanitary sewers, storm drains are not connected to a treatment plant - they flow directly to our local streams, rivers and lakes. Waste orwashwater generated by the food service industry often contains materials such as food wastes, oil, grease, detergents, and degreasers. These materials can degrade local waters when allowed to flow into a storm drain system. Stormwater pollution causes as much as 60% of our water pollution problem. H jeopardizes the quality or our waterways and poses a threat to groundwater resources if pollutants percolate through soil. and Count of Since preventing pollution is much easier, and less costly, than cleaning up "after the fact," the Cities and County of Riverside Storm Water/CleanWaler Protection Program informs residents and businesses on pollution prevention activities such as the Best Management Practices (BMPs) described in this pamphlet. The Cities and County of Riverside have adopted ordinances for stormwater management and discharge control. In accordance with state and federal law, these local stornwater ordinances prohibit the discharge of wastes into the storm drain system or local surface waters. Thisincludes discharges from the food service industry containing food wastes, oil, grease, detergents, and degreasers. PLEASE NOTE: A common stornwater pollution problem associated with the food service industry is the discharge of washwater into alleys and gutters, and the hosing down of outdoor areas. Often, these activities flush pollutants into the storm drain system. The discharges of pollutants is strictly prohibited by local ordinances and state and federal regulations. 0 0 0 A Kenn of Act, Wi es 1, . to Keeps our,, Witter Cleanin' It Right. . Pour mop and wash water into the mop sink or down floor drains ... not into gutters, alleys, parking lots or a storm drain. Wash greasy equipment only in designated =- wash areas which are ="- proteriy connected to the sewer system with an appropriate oil/water separator. Also, avoid washing kitchen mats, garbage containers, and other items in areas where wastewater is likely to flow Into a storm drain. Watch Out For Spills ... Use dry methods for spill cleanup. Don't hose down outside spills. Use rags or absorbents such as f at litter and then ispose of In the arbage, or handle s hazardous waste s appropriate. If necessary, mop the area with a minimum amountof water. Proper Storage and Disposal ... General cleaners, floor cleaners, solvents, and detergents often contain toxic substances. Read labels carefully and store and dispose of these products properly. 6�. REMEMBER: Don't throw toxic waste into the trash or Into a storm drain. To report toxic spill call 911. For information on hazardous waste pick-up call (909) 358.5055. Grease and Oil ... Handle and dispose of grease properly. Save used cooking grease and oil for recycling In tallow bins or sealed containers. Never pour grease into a sink, floor drain, dumpster or stone drain. Watch out for, and report to management, overflowing grease i interceptors. Call (909) 358-51712 for disposal information. How `Bout That Dumpster ... Keep dumpster and loading dock areas clean. Control litter by sweeping - don't hose down the area. Replace leaky dumpsters and keep lids closed to keep out rainwater. Use Water -Friendly Products ... Whenever possible, purchase water-based cleaning products. Look for products labeled "non-toxic," "non -petroleum based," "ammonia -free," "phosphate -free," and "perfume -free, or"readily biodegradable." Everyone contributes a little to the problem of stormwater pollution. Now it's time for all of us to become part of the solution! Clean f Outdoor/Sidewalk Areas ... Sweep up food particles, cigarette butts, and trash from outdoor dining areas before rinsing or steam cleaning. Don't use toxic bleaches or detergents when you pressure wash outdoor dining areas, entrances or surrounding sidewalk areas. You may be already implementing many of the BMPs prescribed in this brochure. However, If you discover any potential problem areas, please consider using one or more of the recommended BMPS. Also, please note that the Riverside County Environmental Health Department will monitor potential sources of stormwater pollution activities during regularly scheduled Inspections of food service facilities. If Health Department staff observe activities which may be contributing to stormwater pollution, suggestions will be provided and/or use of prescribed BMPS listed in this brochure will be offered.

The storm drain system is designed to help prevent flooding by carrying excess rainwater away from streets. Since the storm drain system does not provide for water treatment, it also serves the unintended function of transporting pollutants directly to our waterways. Unlike sanitary sewers, storm drains are not connected to a treatment plant - they flow directly to our local streams, rivers and lakes. In recent years, awareness of the need to protect water quality has increased. As a result, federal, state, and local programs have been established to reduce polluted stormwater discharges to our waterways. The emphasis of these programs is to prevent stormwater pollution since it's much easier, and less costly, than cleaning up "after the fact." M-9011 01140dM-16 arg'stem (NPDES) In 1987, the Federal Clean Water Act was amended to establish a framework for regulating industrial stormwater discharges under the NPDES permit program. In California, NPDES permits are issued by the State Water Resources Control Board (SWRCB) and the nine (9) Regional Water Quality Control Boards (RWQCB). In general, certain industrial facilities and manufacturing operations must obtain coverage under the Industrial Activities Storm Water General Permit if the type of facilities or operations falls into one of the several categories described in this brochure. 0 0 0 How Do /'Know i f l Need -A Permit? Following are general—descriptions of the industry categories types that are regulated by the Industrial Activities Storm Water General Permit. Contact your local Region Water Quality Control Board to determine if your facility/operation requires coverage underthe Permit. i Facilities such as cement manufacturing; feedlots; fertilizer manufacturing; petroleum refining; phosphate manufacturing; steam electric power generation; coal mining; mineral mining and processing; ore mining and dressing; and asphalt emulsion; 1 Facilities classified as lumber and wood products (except wood kitchen cabinets); pulp, paper, and paperboard mills; chemical producers (except some pharmaceutical and biological products); petroleum and coal products; leather production and products; stone, clay and glass products; primary metal Industries; fabricated structural metal; ship and boat building and repairing; 1 Active or inactive mining operations and oil and gas exploration, production, processing, or treatment operations; 1 Hazardous waste treatment, storage, or disposal facilities; 1 Landfills, land application sites and open dumps that receive or have received any industrial waste; unless there is a new overlying land use such as a golf course, park, etc., and there is no discharge associated with the landfill; i Facilities Involved in the recycling of materials, including metal scrap yards, battery reclaimers, salvage yards, and automobile junkyards; i Steam electric powergenerating facilities, facilities that generate steam for electric power by combustion; 1 Transportation facilities that have vehicle maintenance shops, fueling facilities, equipment cleaning operations, or airport deicing operations. This includes school bus maintenance facilities operated by a school district; i Sewage treatment facilities; 1 Facilities that have areas where material handling equipment or activities, raw materials, intermediate products, final products, waste materials, by-products, or industrial machinery are exposed to stone water. How do I obtain coverage under the Industrial Activities Storm Water General Permit? Obtain a permit application package from your local Regional Water Quality Control Board listed on the back of this brochure or the State Water Resources Control Board(SWRCB). Submit a completed Notice of Intent (NOI) forth, site map and the appropriate fee ($250 or 5500) to the SWRCB. Facilities must submit an NOI thirty (30) days prior to beginning operation. Once you submit the NOI, the State Board will send you a letter acknowledging receipt ofyour NOI and will assign yourfacility a waste discharge Identification number (WOID No.). You will also receive an annual fee billing. These billings should roughly coincide with the date the State Board processed your original NOI submittal. What are the requirements of the Industrial Activities Storm Water General.Permit The basic requirements of the Permit are: 1. The facility must eliminate any non-stormwater discharges or obtain a separate permit for such discharges. 2. The facility must develop and implement a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP must identify sources of pollutants that may be exposed to stormwater. Once the sources of pollutants have been identified, the facility operator must develop and implement Best Management Practices (BMPs) to minimize or prevent polluted runoff. Guidance in preparingis SWPPP is available from a document prepared by the California Storni Water Quality Task Force called the California Storm Water Best Management Practice Handbook. 3. The facility must develop and implement a Monitoring Program that includes conducting visual observations and collecting samples of the facility's storm water discharges associated with industrial activity. The General Permit requires that the analysis be conducted by a laboratory that is certified bythe State of California. 4. The facility must submit to the Regional Board, every July 1, an annual report that includes the results of its monitoring program. A Non -Storm Water Discharge is... any A BMP is ... a technique, process, activity, discharge to a storm drain system that is not orstructure used to reduce the pollutantcontent of composed entirely of storm water.

Your pet, family and neighbors will appreciate their clean comfortable surround Ings. HOUSEHOLD PETS We all love our pets, but pet waste is a subject everyone likes to avoid. Pet waste left on trails, sidewalks, streets, and grassy areas is immediately flushed into the nearest waterway when it rains. Even if you can't see water near you, the rain or waste water WASHES all that PET WASTE and BACTERIA INTO THE STORMDRAIN, where it travels to your neighborhood creek or lake untreated. These animal droppings also contain nutrients that can promote the growth of algae, if they enter our streams and lakes. The risk of STORMWATER CONTAMINATION INCREASES, if pet wastes is allowed to accumulate in animal pen areas or left on sidewalks, streets, or driveways where runoff can carry them to storm sewers. Some of the DISEASES THAT CAN SPREAD from pet waste are: Campylobacteriosis — a bacterial infection that causes diarrhea in humans. Salmonellosis — the most common bacterial infection transmitted to humans f rom animals. Toxocarisis — roundworms transmitted from animals to humans. Flies and other pest insects can also increase when pet waste is disposed of improperly, becoming a nuisance and adding yet another vector for disease transmission. WHAT CAN YOU DO? • SCOOP up pet waste and flush it down the toilet. NEVER DUMP pet waste into a storm drain or catch basin. • USE the complimentary BAGS or mutt mitts offered in dispensers at local parks. • CARRY EXTRA BAGS when walking your dog and make them available to other pet owners who are without. TEACH CHILDREN how to properly clean up after a pet. TELL FRIENDS AND NEIGHBORS about the ill effects of animal waste on the environment. Encourage them to clean up after pets.

Any waste left by the animal must cleaned up immediately. CALL YOUR LOCAL CODE ENFORCEMENT OFFICER to find out more about pet waste regulations. Pets are only one of the many fixtures of suburban America that add to water pollution. Lawn fertilizers, rinse water from driveways and motor oil commonly end up in streams and lakes. CALL 1-800-906-2555 FOR HOUSEHOLD HAZARDOUS WASTE COLLECTION LOCATION AND DATES. Maintain your automobile to avoid leaks. Dispose of used vehicle fluids properly. Your pets can be poisoned if they ingest gas, oil or antifreeze that drips onto the pavement or is stored in open containers. NEVER HOSE VEHICLE FLUIDS into the street or gutter. USE ABSORBENT MATERIALS such as cat litter to clean- up spills, SWEEP UP used absorbent materials and place In the trash. HORSES AND LIVESTOCK Fortunate enough to own a horse or livestock? You, too, can play a part in protecting and cleaning up our AA water resources. The following are a few simple Best Management Practices (BMPe) specifically designed for horse owners and landowners with horses. STORE your manure properly. Do not store unprotected piles of manure in places where runoff may enter streams, or flood waters may wash the manure away. Place a cover or tarp over the pile to keep rainwater out. CHECK with your local conservation district to design manure storage facilities to protect water quality. These structures usually consist of a concrete pad to protect ground water and a short wall on one or two sides to make manure handling easier, ?s �s dy -, dS..;6 Ds ds tf1 ((t ktas' ds TRY composting - A vegetative placed around buildings or on steeper slopes can help minimize erosion and absorb nutrients while � improving the t! appearance of your property. In addition, avoid costlier erosion cover controls, vegetative covers will provide animals with better traction during wet or icy conditions. KEEP animals out of steams - Designed stream crossings provide a safe, easy way for horses and livestock to ford streams. Fencing encourages the use of the crossing instead of the streambed to navigate streams. This will allow vegetation to stabilize stream banks and reduce sediment pollution. MOW pastures to proper height, six inches is typically recommended. Material STORAGE SAFETY TIPS - Many of the chemicals found in barns require careful handling and proper disposal. When using these chemicals, be certain to follow these common sense guidelines; Buy only what you need, Treat spills of hoof oils like fuel spill. Use kitty litter to soak up the oil and dispose in a tightly sealed plastic bag. Store pesticides in a locked, dry, well -ventilated area, Protect stored fertilizer and pesticides from rain and surface water. Call 1-800-906-2559 to locate your local conservation district to find out what to do with your current backyard manure pile, how to re-establish a healthy pasture, what to do about weeds, and what grasses grow best in your soils.

Polluted runoff contaminates local waterways and poses a threat to groundwater resources. Unlike sanitary sewers, storm drains are not connected to a treatment plant - they flow directly to our local streams, rivers and lakes. Soaps, degreasers, automotive fluids, litter, and a host of other materials washed off buildings, sidewalks, plazas, parking areas, vehicles, and equipment can all pollute ourwatenvays. e INS aad,nfliu d Rium9de pollution is much easier, and less c-ostly than cleaning up 'after the Fact," the of Riverside Sloe rn Water/C lea rArl-J2r Protection P'rogi am informs residents and utlon prevention activities such a: iarse described in this pamphlet. fhe Cities and County of i iversldo have adopted - tlnances for sormwater management and discharge control.

Understand that water (without soap) used to remove dust from clean vehicles may be discharged to a street or storm drain. Washwater from sidewalk, plaza, and building surface cleaning may go into a street or storm drain if ALL of the following conditions are met: 1) The surface being washed is free of residual oil stains, debris and similar pollutants by using dry cleanup methods (sweeping, and cleaning any oil or chemical spills with rags or other absorbent materials before using water). 2) Washing is done with water only -no soap or other cleaning materials. 3) You have not used the water to remove paint from surfaces during cleaning.

The purpose of this study was to • perform percolation testing within the subject property for use in the design of the proposed water quality swale on the subject site. Submitted herewith are the results of this firm's findings, along with the supporting data. 1.0 PROPOSED DEVELOPMENT The proposed development will consist of five (5) commercial buildings, along with associated hardscape and landscape improvements. Capture of storm water run-off for the proposed development on the subject parcels will be managed by the use of the proposed water quality swale. 2.0 SITE DESCRIPTION The site consists of approximately 4.37 -acres located on the south side of Nicolas Road, east of the intersection of Nicolas Road and Winchester Road, in the City of Temecula, County of Riverside, California. The site is currently undeveloped, cleared land with a Jack in the Box on the adjacent property to the west. The site is relatively flat with regional drainage primarily by sheet flow to the north-northwest. A storm drain inlet was observed in the northwest corner of the subject property. At the time of the field study, no wells were observed within 100 -feet of the proposed infiltration area.

(MTGL, 2006). The scope of work for the current project does not include review of the previous report. 3.2 TEST HOLE EXCAVATION Three (3) eight -inch diameter exploratory borings (P1, P2, and P3) were excavated on the subject property to depths of 20 -feet below surface elevation, respectively, within the area of the proposed water quality swale per the City of Temecula. Upon completion of testing, the exploratory borings were not backfilled. It is recommended that the borings be backfilled with reasonable effort to restore the area to its natural condition as a temporary safety precaution. The client is advised to periodically examine the excavated area and, if necessary, backfill any noted depressions. 3.3 PERCOLATION TESTING • The percolation test areas were verified as being in undisturbed natural earth materials. Upon completion of the excavation of the three (3) exploratory borings, 4 -inch diameter perforated PVC pipe was placed in each hole. The percolation test holes were filled with water and allowed to presoak for a minimum of 24 hours prior to testing. Percolation testing was performed in general accordance with the procedures outlined in Chapter 3 of the "Waste Disposal for Individual Homes, Commercial and Industrial' publication issued by the Riverside County Department of Environmental Health. A time interval of 30 minutes was used for the test readings. The percolation test results are presented in Section 5.1. 4.0 SUBSURFACE CONDITIONS 4.1 EARTH MATERIALS The earth materials encountered within the exploratory borings previously excavated on the subject parcel consisted of alluvium to the maximum depths explored (20.0 -feet bgs). Refusal was not encountered within 20.0 -feet of the surface in the areas explored. 4.2 GROUNDWATER Groundwater was not encountered within 20.0 -feet of the surface in the areas explored. 0 0 5.0 PERCOLATION TEST DATA 5.1 RESULTS Chaparral Village Project Number M3695 -P August 2007 Page 5 The following table presents the actual drop in water level recorded in the test holes during percolation testing. ;LOCATIOW -mDuRATION HOURS "r„WATER iliVE-06�6p-jjFigm Pi 9:00 AM 0.5 10.5 P1 9:30 AM 0.5 8.8 Pi 10:00 AM 0.5 7.2 Pi 10:30 AM 0.5 6.8 Pi 11:00 AM 0.5 6.4 Pi 11:30 AM 0.5 6.5 Pi 12:00 PM 0.5 6.5 Pi 12:30 PM 0.5 6.5 Pi 1:00 PM 0.5 6.5 Pi 1:30 PM 0.5 6.5 Pi 2:00 PM 0.5 6.5 Pi 2:30 PM 0.5 6.4 1�1 Resulting infiltration rate @ P1 = 153.6 in/hr U(X"AUT'116`�d io, E P2 9:00 AM 0.5 6.4 P2 9:30 AM 0.5 4.9 P2 10:00 AM 0.5 3.7 P2 10-30 AM 0.5 2.2 P2 11:00 AM 0.5 2.4 P2 11:30 AM 0.5 2.4 P2 12:00 PM 0.5 2.1 P2 12:30 PM 0.5 2.0 P2 1:00 PM 0.5 2.0 P2 1:30 PM 0.5 2.1 P2 2:00 PM 0.5 2.1 P2 2-30 PM 0.5 2.0 Resulting infiltration rate @ P2 = 48.0 in/hr 40 Ch p rr I Vill e Project Number: M3695 -P .

We are pleased to present the following report with our conclusions and recommendations for remedial grading and foundations. EXECUTIVE SUMMARY Although building plans or preliminary loads are not available at this time we have assumed normal foundation loading of 50 to 75 kips for pad footings and 3 to 6 kips per foot for perimeter footings. If expected loads exceed these ranges we should be consulted for additional foundation recommendations. Our report concludes that the site is suitable for construction if the recommendations presented are incorporated into the plans and specifications for the proposed construction. Removals and recompaction of onsite soils beneath the structures are recommended to be 2 feet below proposed foundation or 4 feet from existing ground surface, whichever is lower in elevation. Removals in hardscape and paving areas are expected to be 2 foot below subgrade. The onsite soils have low expansion potential and the moisture content of the subgrade soils below foundations and slabs on grade should be near the optimum to a depth of 18 inches prior to placing concrete. The soils are potentially corrosive to ferrous metals.

Chaparral Village INTRODUCTION Project No. 6625-A01 Log No. 06-1470 In accordance with your request and authorization, MTGc, Inc. has completed a Preliminary Geotechnical Investigation for the subject site. The following report presents our findings, conclusions and recommendations based on our investigation, laboratory testing, and engineering review. PLANNED CONSTRUCTION It is proposed to construct two (2) single story wood framed structures comprising approximately 26,500 square feet along with site improvements including access and parking paving. See the Boring Location Plan (Figure 2) for approximate location of the planned construction. SCOPE The scope of our Geotechnical services included the following: • Complete a Preliminary Geotechnical Investigation consisting of excavating 4 borings. (See Appendix B for Logs and Boring Location Plan for Locations) • Laboratory testing of samples (See Appendix Q. • Geotechnical engineering review of data and engineering recommendations. • Preparation of this report summarizing our findings and presenting our conclusions and recommendations for the proposed construction. SITE The site is located just east of the intersection of Winchester Road and Nicolas Road in the City of Temecula. The site is currently an empty lot adjacent to the existing Jack in the Box restaurant and an existing gas station. The site is vegetation free and is relatively flat. Page 1 0 DBI Retail Ventures, LLC. Chaparral Village LABORATORY TESTING M Project No. 6625 -AOI Log No. 06-1470 The laboratory testing consists of moisture density determinations of the relatively undisturbed samples and moisture content of the disturbed samples. Grain Size, Atterberg Limits and 4200 Wash were determined for soils classification and liquefaction analysis. The maximum density was determined on samples of the near surface soils so that an estimated shrinkage during grading could be made. Direct shear and consolidation testing were accomplished for foundation bearing and settlement determinations. Corrosivity, Expansion Index and Soluble Sulfates in the near surface soils were determined for slab -on - grade and concrete recommendations. R -Value testing was completed for hardscape and pavement recommendations. The results and expanded explanation of laboratory testing are presented in Appendix C and on the Boring Logs, Appendix B. Page 2 0 DBI Retail Ventures, LLC. Project No. 6625-A01 Chaparral Village Log No. 06-1470 GEOLOGY / SIESMICITY Regional Geologic Conditions The site area is located within the Elsinore -Temecula Trough in the Peninsular Ranges geomorphic province. The Elsinore -Temecula Trough extends from the Lake Elsinore Basin, north of the Temecula, to the Agua Tibi Mountains, located south of Temecula. Topographically, the site lies in a relatively flat area at an elevation of approximately 1100 feet above sea level. Structurally, the area lies within the broad Elsinore Fault Zone with the Santa Ana Mountains to the west and the Perris Block to the northeast. Quaternary alluvial deposits reportedly reach thicknesses of up to approximately 3,000 feet in the central portion of the Elsinore -Temecula Trough. Within the Elsinore Trough, these sediments overlie pre -Tertiary crystalline bedrock. The Tertiary Bedford Canyon Formation underlies the Santa Rosa Mountains southwest of the Temecula Valley. • Site Geologic Conditions The site is located along the south side of Nicolas Road between Rorlpaugh Road and Winchester Road in Temecula, California. The ground surface is relatively flat and slopes gently toward the west at a slope angle of approximately 40 feet per mile. The site vicinity is drained by Santa Gertrudes Creek. The site is underlain by alluvium derived from weathering of poorly consolidated and poorly -cemented silty sandstone of the Quaternary age Pauba formation that crops out on the hills in the immediate site vicinity (CDMG, 1991). Where encountered in the borings advanced for this investigation, the native alluvium consists of brown, moist, dense to very dense silt and sand with scattered gravel and was generally encountered at a depth of approximately 1 -foot below the existing plowed ground. According to the USDA Soil Conservation Service (1971), soils of the Hanford-Tujunga- Greenfield soil association occur across the majority of the site. Based on samples retrieved from the soil borings, and review of the Soil Conservation Service soils report, the most of the site is underlain by fine sandy loam associated with the Hanford soil series. The soils which comprise the Hanford soil series consist of well drained to somewhat excessively • drained soils on alluvial fans with slopes ranging from 0 to 15 percent. Typically, the upper Page 3 11 • • DBI Retail Ventures, LLC. Chaparral Village Project No. 6625-A01 Log No. 06-1470 18 inches of the soil profile is grayish brown coarse sandy loam underlain by brown, stratified coarse sandy loam and loamy sand to a depth of approximately five (5) feet. Historically, these soils have been used for dryland pasture, grains and for irrigated alfalfa , potatoes, citrus, and grapes. More recently, they have been extensively developed for homesites and other developments. According to USDA (1977), the Hanford soil series has low shrink swell potential and pH values of approximately 6.1 to 7.8. Groundwater Conditions Groundwater was encountered at a depth of approximately 34 -feet below ground surface in boring Bl. It is considered possible that, in the future, due to changes in runoff and infiltration associated with regional site development, groundwater depths could become shallower. Due to the generally fine-grained nature of the near surface soils, sudden fluctuations of groundwater at the site are not likely. Seismic Hazards The site is located within the seismically active area of southern California. However, no active faults appear to exist on the site or immediately adjacent to the site. Seismic risk is considered relatively high as compared to other areas of southern California, mainly because of the relatively close proximity to active faulting along the Elsinore Fault zone. Based on review of the Fault -Rupture Hazards Zones in California, the site is not located within an earthquake hazard zone. The site is located east of the Elsinore Fault Zone, and south of the Murrieta Hot Springs Fault (north of Murrieta Hot Springs Road). The Elsinore Fault Zone is an active northwest trending strike slip fault with probable vertical displacement of up to 1,500 feet or more and is the major structural feature influencing the site and site vicinity. The Elsinore fault is located approximately three (3) miles southwest of the site. Primary seismic hazards in the site and site vicinity. include severe ground shaking, actual surface rupture due to faulting, and secondary ground failures such as liquefaction, ground lurching, lateral spreading, seiche, tsunami, and landslides. Due to the presence of numerous active faults within the southern California region, severe ground shaking potential is considered high. However, the actual surface rupture potential due to faulting Page 4 9 DBI Retail Ventures, LLC. Chaparral Village Project No. 6625-A01 Log No. 06-1470 across any portion of the site is considered very low. Liquefaction is the temporary loss of cohesion in saturated, granular soils subjected to ground shaking. Because of the soil types encountered in the four (4) soil borings, the seismic setting of the site, and the depth to groundwater, a liquefaction analysis was conducted (see below). Lateral spreading is the horizontal movement of loose, unconsolidated sedimentary deposits or imported fill material. Lateral spreading potential is considered low. Ground lurching is the horizontal movement of soil, sediments or fill founded on steep slopes and embankments. Due to the relatively flat surface and lack of significant embankments, lateral spreading potential is considered very low. A seiche is the periodic oscillation of a body of water resulting from seismic shaking. As there are no surface impoundments or reservoirs in the immediate site vicinity, seiche potential is also considered nil. Because the site is located a sufficient distance inland from the coast and at an elevation of approximately 1100 feet above sea level, inundation by tsunamis is not an issue. Finally, landslides are unlikely due to the relatively flat topography at the site and surrounding site vicinity. • Liquefaction Liquefaction occurs in water -saturated sediments during moderate to great earthquakes and results in loss of strength which can damage structures. The soils at the site locally have clean, medium dense sand layers within 40 feet or less of the ground surface and the site is in relatively close proximity to active faults. Although the regional groundwater depth at the site was in excess of 34.0 feet below grade at the time of the field investigation, future land use changes, utility line leakages and over -irrigation could cause shallow groundwater or perched groundwater conditions to develop, especially given the presence of low - permeable interbeds of silt and clay. Review, of CDMG (2000) and CDMG (2001) suggests that the site soils have no to low susceptibility to liquefaction. Nevertheless, based on the findings of our investigation, a liquefaction analysis was conducted (see below). Liquefaction, the process by which water -saturated sediment loses strength and may fail during strong ground shaking, commonly accompanies moderate to great earthquakes throughout the world. Water -saturated, cohesionless, granular sediment situated at depths less than 50 feet beneath the surface constitutes the principal environs of the liquefaction _ process. A liquefaction assessment was completed using current standards and California T • Special Publication 117. Page 5 11 DBI Retail Ventures, LLC. Chaparral Village Project No. 6625-A01 Log No. 06-1470 A liquefaction study was conducted based on the subsurface conditions encountered at B-1, using current standards and California Special Publication 117, and an assumed ground water table of 20 feet below ground surface. Details of the liquefaction analysis are presented in Appendix D. Based on the liquefaction study, there are sand layers that mayl liquefyyduring the life of the project due to the design earthquake. Liquefaction of the zone 'would cause up to .1.63 inch of settlement? Due to relatively level nature of the subgrade, this settlement is expected to produce a maximum of 3/4 inch of differential settlement. The recommended remedial grading may reduce some of the estimated settlements. However, we recommend that the structures to be designed to tolerate 1.5 inch and 3/4 -inch of total and differential settlement respectively. Landslides and Slope Stability • The slope gradient at the site is approximately 40 feet per mile toward the southwest. Slope stability is not considered an issue on this gently sloping, developed site. Further, according to CDMG (2001), the site is not within a designated landslide zone. Seismicity The computer program FRISKSP (Thomas F. Blake, 2000) was used to calculate the site accelerations using the probabilistic method. See Appendix D for results. The Design -Basis Earthquake ground -motion (10% chance of exeedance in 50 years) is 0.60g. The Upper - Bound Earthquake Ground -Motion (10% chance of exeedance in 100 years) is 0.75 g. The computer program UBSEIS (Thomas F. Blake, 2000) was used to calculate the UBC seismic factors. The results are located in the Appendix. The site soil profile is SD. The nearest active fault is the Elsinore -Temecula fault, which is located approximately 3 miles away. The fault type is B. Selected UBC seismic coefficients are: Na = 1.0, Nv = 1.2, Ca = 0.45 and Cv = 0.79 (Other parameters may be found in Appendix D). The computer program EQFAULT (Thomas F. Blake, 2000) was used to deterininistically • calculate the maximum peak ground acceleration for the site. Based on the results, the site may experience a maximum peak ground acceleration of 0.415 g.

Project No. 6625-A01 Chaparral Village Log No. 06-1470 CONCLUSIONS General Conclusions Given the findings of the investigation, it appears that the site geology is suitable for the proposed construction provided our conclusions are taken into consideration during design, and our recommendations are incorporated into the construction plans and specifications and implemented during grading and construction. Based on the investigation, it is our opinion that the proposed development is safe against landslides and ground rupture from active faults. Grading and construction of the proposed project will not adversely affect the geologic stability of adjacent properties. The nature and extent of the investigation I7 conducted for the purposes of this declaration are, in our opinion, in conformance with generally accepted practice in this area. There appears to be no significant onsite geologic constraint that cannot be mitigated by proper planning, design, and sound construction •o practices. _• Excavation Characteristics/Shrinkage Based on the drilling for the subsurface investigation, which was done by hollow stem auger, excavation of the onsite soil materials can use conventional earthmoving equipment. Shrinkage of the undocumented fill and alluvium is expected to be 10 to 15 percent. Settlement Considerations Based on the known subsurface conditions and site geology, we anticipate that properly designed and constructed foundations supported on the recommended material would experience total and differential settlement. As a minimum all foundations bearing into the engineered fill should be designed to accommodate a total settlement of at least one inch with a differential settlement of 1/2 inch over a horizontal distance of 50 feet. Page 7 9 DBI Retail Ventures, LLC. Chaparral Village Expansion Potential/Fill Project No. 6625-A01 Log No. 06-1470 The onsite soils are suitable for use as fill if organic debris is removed prior to placement as fill. Expansion potential is expected to be very low. Corrosivity and the On -Site Soils Based on testing and our experience, concrete in contact with the on-site soils may utilize type II Cement due to low soluble sulfates. Based on the Corrosivity test results, the onsite soils will be potentially corrosive to ferrous metals. We recommend Corrosion Engineers be consulted for any ferrous material that may be installed in direct contact with onsite soils. Site Coefficient/Subaade Modulus • The Subgrade Modulus may be taken as 105 psi per inch. In compliance with the 1997 Uniform Building Code the site is Type SD and the Seismic Coefficients presented in Appendix D may be used. RECOMMENDATIONS Our recommendations are considered minimum and may be. superseded by more conservative requirements of the architect, structural engineer, building code, or governing agencies. The foundation recommendations are based on the expansion index and shear strength of the onsite soils. Import soils, if necessary should not exceed the existing expansion potential and should be — approved by the Geotechnical Engineer prior to importing to the site. In addition to the recommendations in this section, additional general earthwork and grading specifications are included in Appendix E. Site Grading Recommendations General Compaction Standard: All fills should be compacted to at least 90 percent of maximum dry density as determined by ASTM Test Method D1557-96. Fill materials • should be placed in loose lifts, not thicker than 8 inches. Material should be moisture - Page 8 DBI Retail Ventures, LLC. Project No. 6625-A01 Chaparral Village Log No. 06-1470 conditioned as processed as necessary to achieve a uniform moisture content that is over optimum and within moisture limits required to achieve adequate bonding between lifts and - compaction. Site Overexcavation Building plans, grading plans and foundation elevations are not available at this time. When these plans become available this office should review them in order to make additional I recommendations, if necessary All organics, debris, trash and topsoils should be removed offsite. To provide a uniform bearing support across the proposed building pad, we recommend the pad area to be over excavated to a minimum of 4 feet below the existing surfacd or 2 feet below the bottom of footings, whichever is lower in elevation. The horizontal limits of over excavation beyond f the perimeter footings should be equal to the depth of over excavation, but not less than 5 k� feet. Hardscape areas which include paving sections will require a minimum of 2 feet of removal and recompaction. Processing for hardscape should extend to a minimum of 2 feet outside the structural limits. The excavated on site material, moisture conditioned to approximately the optimum moisture content, could be used for back fill in the over excavation. The fill should be compacted to a minimum of 90% of the maximum dry density per ASTM D-1557-96. I_. Foundation and BuildingSlabs labs Spread Footings An allowable bearing pressure of 2,000 psf may be used for conventional shallow footing design for the minimum embedment recommended below. This value may be increased by j 200 psf per additional foot of embedment and 100 psf per foot of width for a total not to exceed 3,000 psf. The allowable bearing pressure may be increased by one-third for wind or seismic loading. Continuous footing should be reinforced with one 44 reinforcing steel bars, top and bottom as a minimum. The recommended minimum footing widths are 12 Page 9 0 0 • DBI Retail Ventures, LLC. Chaparral Village Project No. 6625-A01 Log No. 06-1470 and 24 inches for continuous and isolated footings respectively. The embedment should be a minimum of 24 inches for perimeter footings or 18 inches for interior footings Soil resistance developed against lateral structural movement can be obtained from the passive pressure value of 300 pcf. Further, for sliding resistance, a friction coefficient of 0.3 may be used at the concrete and soil interface. In combining the total lateral resistance, either the passive pressure or the friction of resistance should be reduced by 50 percent. In addition, the lateral passive resistance is taken into account only if it is ensured that the soil against embedded structures will remain intact with time. Concrete and the On -Site Soils Based on testing and our experience, concrete in contact with the on-site soils may utilize type II Cement. Retail Walls Embedded structural walls should be designed for lateral earth pressures exerted on them. The magnitude of these pressures depends on the amount of deformation that the wall can yield under load. If the wall can yield enough to mobilize the full shear strength of the soil, it can be designed for "active" pressure. If the wall cannot yield under the applied load, the shear strength of the soil cannot be mobilized and the earth pressure will be higher. Such walls as basement and swimming pools should be designed for the "at rest" conditions. If a structure moves toward the soils, the resulting resistance developed by the soil is the "passive" resistance. For design purposes, the recommended equivalent fluid pressure for each case for walls founded above the static ground water table and backfilled with nonexpansive soils is provided below. Retaining wall backfill should be compacted to at least 90 percent relative compaction (based on ASTM Test Method D1557-91). Recommended pressures are shown on Table 1. Page 10 r DBI Retail Ventures, LLC. Chaparral Village Table 1. Project No. 6625-A01 Log No. 06-1470 It is recommended that the footings be embedded at least 24 inches below lowest adjacent finish grade. In addition, the wall footings should be designed and reinforced with structural considerations. For walls less than 15 feet in height, the back cut should be flattened to a gradient of not steeper and 1:1(H: V) slope inclination. The walls may be drained by a vertical layer of Miradrain 6200 with Mirafi 140 Geofabric, or equivalent, placed at the back of the wall; or by a minimum 12 -inch width of 3/4 inch open -graded crushed gravel enveloped in Mirafi. 140 Geofabric. Subdrains should consist of 4 -inch diameter Schedule 40, PVC pipe or equivalent, embedded in approximately 1 ft3/linear foot of 3/4 -inch down open -graded gravel, enveloped in Mirafi 140 Geofabric Filter or equivalent, with the pipe being 3+ inches above the trench bottom; a gradient of at least 1% being provided to the pipe and trench bottom; discharging into suitably protected outlets. Alternatively low retaining walls (less than 5 feet retained) may use weep holes. The Factor of Safety used in calculating the above fluid pressures and coefficient is 1.5. Slab -on -grade Recommendations The recommended minimum slab -on -grade should be a nominal 5 inches in thickness, reinforced with 43 reinforcing bars on 18 -inch centers in both directions. A thicker slab -on - grade with heavier reinforcement may be required based upon the proposed loading . conditions in the structure. Anticipated dynamic settlements due to liquefaction should be also considered in the design of slab thickness and reinforcements. Page 11 0 DBI Retail Ventures, LLC. Chaparral Village Project No. 6625-A01 Log No. 06-1470 Where moisture sensitive flooring is anticipated the placement of membrane with 2 inches of free draining sand placed above and below the membrane is recommended. The membrane as a minimum should be 10 -mil visqueen. Prewetting Recommendation Due to the low expansion potential of the onsite soils, the soils underlying the slab -on -grade should be prewetted only to prevent water loss in the concrete foundations and slabs. Pavement Recommendations We have assumed a Traffic Index of 4 for parking areas, 5.5 for travel lanes and 7.5 for • heavy truck lanes. Where the pavement is subject to repeated turning stress (i.e. Trash Enclosures Aprons) the pavement should be PCC. Based on the R -Value test result of 19, we recommend the following pavement sections. PAVEMENT ,- i TRAFFIC AC_ BASE AREA INDEX THICKNESS THICKNESS _ .- Parking Areas 4.0 3.0 inches 5.0 inches Driveways 5.5 4.0 inches 8.0 inches Heavy Truck Lanes 7.5 6.0 inches 11.0 inches Base for paving should be compacted to 95 percent of maximum in accordance with the overexcavation section. Minimum reinforcing should be considered for the concrete and the concrete should be placed on subgrade compacted to 90 percent of ASTM D 1557. The R -Value should be confirmed and the sections recalculated where necessary at the completion of grading. • Page 12 DBI Retail Ventures, LLC. Project No. 6625-A01 Chaparral Village Log No. 06-1470 Construction Considerations Moisture Sensitive Soils/Weather Related Concerns The upper soils encountered at this site may be sensitive to disturbances caused by construction traffic and to changes in moisture content. During wet weather periods, increases in the moisture content of the soil can cause significant reduction in the soil strength and support capabilities. In addition, soils that become wet may be slow to dry and thus significantly retard the progress of grading and compaction activities. It will, therefore, be advantageous to perform earthwork and foundation construction activities during dry weather. Much of the on-site soils may be susceptible to erosion during periods of • inclement weather. As a result, the project Civil Engineer/Architect and Grading Contractor should take appropriate precautions to reduce the potential for erosion during and after construction. Drainage and Groundwater Considerations Groundwater was encountered at approximately 34 feet below existing grade. It should be noted, however, that variations in the ground water table may result from fluctuation in the ground surface topography, subsurface stratification, precipitation, irrigation, and other factors that may not have evident at the time of our exploration. This sometimes occurs where relatively impermeable and/or cemented formational materials are overlain by fill soils. In addition, during retaining wall excavations, seepage may be encountered. We recommend that a representative of MTGL, Inc. be present during grading operations to evaluate areas of seepage. Drainage devices for reduction of water accumulation can be recommended if these conditions occur. Water should not be allowed to collect in the foundation excavation, on floor • slab areas, or on prepared subgrades of the construction area either during or after Page 13 DBI Retail Ventures, LLC. Chaparral Village Project No. 6625-A01 Log No. 06-1470 construction. Undercut or excavated areas should be sloped toward one corner to facilitate removal of any collected rainwater, groundwater, or surface runoff. Positive site drainage should be provided to reduce infiltration of surface water around the perimeter of the building and beneath the floor slabs. The grades should be sloped away from the building and surface drainage should be collected and discharged such that water is not permitted to infiltrate the backfill and floor slab areas of the building. . Excavations In Federal Register, Volume 54, No. 209 (October 1989), the United States Department of Labor, Occupational Safety and Health Administration (OSHA) amended its "Construction Standards for Excavations, 29 CFR, part 1926, Subpart P". This document was issued to better insure the safety of workmen entering trenches or excavations. It is mandated by this federal regulation that excavations, whether they be utility trenches, basement excavation or foundation excavations, be constructed in accordance with the new OSHA guidelines. It is our understanding that these regulations are being strictly enforced and if they are not closely followed the owner and the contractor could be liable for substantial penalties. The contractor is solely responsible for designing and constructing stable, temporary excavations and should shore, slope, or bench the sides of the excavations as required to maintain stability of both the excavation sides and bottom. The contractor's "responsible person", as defined in 29 CFR Part 1926, should evaluate the soil exposed in the excavations as part of the contractor's safety procedures. In no case should slope height, slope inclination, or excavation depth, including utility trench excavation depth, exceed those specified in local, state, and federal safety regulations. Utility Trenches Except where extending perpendicular under proposed foundations, utility trenches Page 14 9 DBI Retail Ventures, LLC. Chaparral Village Project No. 6625-A01 Log No. 06-1470 should be constructed outside a 1:1 projection from the base -of -foundations. Trench excavations for utility lines, which extend under structural areas should be properly backfilled and compacted. Utilities should be -bedded and backfilled with clean sand or approved granular soil to a depth of at least 1 -foot over the pipe. This backfill should be uniformly watered and compacted to a firm condition for pipe support. The remainder of the backfill shall be typical on-site soil or imported soil which should be placed in lifts not exceeding 8 inches in thickness, watered or aerated close to optimum moisture content, and mechanically compacted to at least 90 percent of maximum dry density (based on ASTM D1557). Site Drainage . The site should be drained to provide for positive drainage away from structures in accordance with the building code and applicable local requirements. Unpaved areas should slope no less than 2% away from structure. Paved areas should slope no less than 1% away from structures. Concentrated roof and surface drainage from the site should be collected in engineered, non-erosive drainage devices and conducted to a safe point of discharge. The site drainage should be designed by a civil engineer. Geotechnical Observation/Testing of Earthwork Operations The recommendations provided in this report are based on preliminary design information and subsurface conditions as interpreted from the investigation. Our preliminary conclusion and recommendations should be reviewed and verified during site grading, and revised accordingly if exposed Geotechnical conditions vary from our preliminary findings and interpretations. The Geotechnical consultant should perform Geotechnical observation and testing during the following phases of grading and construction: During site grading and overexcavation. During foundation excavation and placement. • Upon completion of any foundation and retaining wall footing excavation prior to Page 15 DBI Retail Ventures, LLC. Chaparral Village Project No. 6625-A01 Log No. 06-1470 placing concrete. During excavation and backfilling of all utility trenches During processing and compaction of the subgrade for the access and parking areas and prior to construction of pavement sections. When any unusual or unexpected Geotechnical conditions are encountered during any phase of construction. LMTATIONS The analyses, conclusions, and recommendations contained in this report are based on site conditions as they existed at the time of our investigation and further assume the explorations to be representative of the subsurface conditions throughout the site. If different subsurface conditions are observed during construction, we should be promptly notified for review and reconsideration of our recommendations. • This report was prepared for the exclusive use and benefit of the owner, architect, and engineer for evaluating the design of the facilities as it relates to geotechnical aspects. It should be made available to prospective contractors for information on factual data only, and not as a warranty of subsurface conditions included in this report. Our investigation was performed using the standard of care and level of skill ordinarily exercised under similar circumstances by reputable soil engineers and geologists currently practicing in this or similar localities. No other warranty, express or implied, is made as to the conclusions and professional advice included in this report. _0 Page 16 i1 U APPENDIX A REFERENCES 1.

The approximate location of the borings are shown on the Boring Location Plan, Figure 2, attached. The field exploration was performed under the supervision of our Geologist who maintained a continuous log of the subsurface soils encountered and obtained samples for laboratory testing. Subsurface conditions are summarized on the Logs of Borings. The soils encountered were classified in general accordance with the Unified Soil Classification System (see Key to Logs, Figure B-0). • The borings were located in the field by pacing and measuring, working from appropriate locations on a map. The soils were classified based on field observations and laboratory tests. The borings were backfilled with cuttings, compacted and patched. 9 • Is W W Q OCOLAS ROAD 'N 0 Boring Location Plan Figure 2 DEFINITION OF TERMS PRIMARY DIVISIONS SYMBOLS SECONDARY DIVISIONS CLEAN G W graded gravels, gravel-sand mixtures, little or no well ¢ GRAVELS GRAVELS _' ®.

These specifications present general procedures and requirements for grading and earthwork as shown on the approved grading plans, including preparation of areas to be filled, placement of fill, installation of subdrains, and excavations. The recommendations contained in the attached geotechnical report are a part of the earthwork and grading specifications and shall supersede the provisions contained herein in the case of conflict. Evaluations performed by the Consultant during the course of grading may result in new recommendations, which could supersede these specifications, or the recommendations of the geotechnical report. 2. EARTI-nrnRxnBgFR17ATTO7.TArmTF-,TTT�T(- Prior to the start of grading, a qualified Geotechnical Consultant (Geotechnical Engineer and Engineering Geologist) shall be employed for the purpose of observing earthwork procedures and testing the fills for conformance with the recommendations of the geotechnical report and these specifications. It will be necessary that the Consultant provide adequate testing and observation so that he may determine that the work was accomplished as specified. It shall be the responsibility of the Contractor to assist the Consultant and keep them apprised of work schedules and changes so that he may schedule his personnel accordingly. It shall be the sole responsibility of the Contractor to provide adequate equipment and methods to accomplish the work in accordance with applicable grading codes or agency ordinances, these specifications and the approved grading plans. Maximum dry density tests used to determine the degree of compaction will be performed in accordance with the American Society for Testing and Materials Test Method (ASTM) D1557-91 or later revision. 3. PRFPARATTTIWnFARFACTn RFFTTTFD Clearing—�-_n dr;"bbi^All brush, vegetation and debris shall be removed or piled and otherwise disposed of. Prnr� The existing ground which is determined to be satisfactory for support of fill shall be scarified to a minimum depth of 6 inches. Existing ground, which is not satisfactory, shall be overexcavated as specified in the following section. Cluexexcavatiou Soft, dry, spongy, highly fractured or otherwise unsuitable ground, extending to such a depth that surface processing cannot adequately improve the condition, shall be overexcavated down to firm ground, approved by the Consultant, A,fnichnra rnnAiHnnino• Overexcavated and processed soils shall be watered, dried -back, blended, and mixed as required to have a relatively uniform moisture content near the optimum moisture content as determined by ASTM D1557. Recnmpaclionc Overexcavated and processed soils, which have been mixed, and moisture conditioned uniformly shall be recompacted to a minimum relative compaction of 90 percent of ASTM D1557. Renrhing- Where soils are placed on ground with slopes steeper than 5:1 (horizontal to vertical), the ground shall be stepped or benched. Benches shall be excavated in firm material for a ndnimum width of 4 feet. • ¢ FIT T lvI ATFRTAT General: Material to be placed as fill shall be free of organic matter and other deleterious substances, and shall be approved by the Consultant. Lwersfzec Oversized material defined as rock, or other irreducible material with a maximum dimension greater than 12 inches, shall not be buried or placed in fill, unless the location, material, and disposal • methods are specifically approved by the Consultant. Oversize disposal operations shall be such that nesting of oversized material does not occur, and such that the oversize material is completely surrounded by compacted or densified fill. Oversize material shall not be placed within 10 feet vertically of finish grade or within the range of future utilities or underground construction, unless specifically approved by the Consultant. Import- If importing of fill material is required for grading, the import material shall meet the general requirements. 5. Ell r FT AC EMINIT AND rnr,snAC TION Fill Lifts Approved fill material shall be placed in areas prepared to receive fill in near -horizontal layers not exceeding 6 inches in compacted thickness. The Consultant may approve thicker lifts if testing indicates the grading procedures are such that adequate compaction is being achieved with lifts of greater thickness. Each layer shall be spread evenly and shall be thoroughly mixed during spreading to attain uniformity of material and moisture in each layer. Fill Moisture- Fill layers at a moisture content less than optimum shall be watered and mixed, and wet fill layers shall be aerated by scarification or shall be blended with drier material. Moisture conditioning and mixing of fill layers shall continue until the fill material is at uniform moisture content at or near optimum. C'nm„on of F;»- .

Runoff is stored in the void space between the stones and infiltrates through the bottom and into the soil matrix. Infiltration trenches perform well for removal of fine sediment and associated pollutants. Pretreatment using buffer strips, swales, or detention basins is important for limiting amounts of coarse sediment entering the trench which can clog and render the trench ineffective. inspection/ Maintenance Considerations Frequency of clogging is dependant on effectiveness of pretreatment, such as vegetated buffer strips, at removing sediments. See appropriate maintenance factsheets for associated pretreatment. If the trench clogs, it may be necessary to remove and replace all or part of the filter fabric and possibly the coarse aggregate. Clogged infiltration trenches with surface standing water can become a nuisance due to mosquito breeding. Maintenance efforts associated with infiltration trenches should include frequent inspections to ensure that water infiltrates into the subsurface completely at a recommended infiltration rate of 72 hours or less to prevent creating mosquito and other vector habitats. Most of the maintenance should be concentrated on the pretreatment practices, such as buffer strips and swales upstream of the trench to ensure that sediment does not reach the infiltration trench. Regular inspection should determine if the sediment removal structures require routine maintenance. Infiltration trenches should not be put into operation until the upstream tributary area is stabilized.

Replace first layer of aggregate and filter fabric if clogging appears only to be at the surface. ■ Clean trench when loss of infiltrative capacity is observed. If drawdown time is observed to have increased significantly over the design drawdown time, removal of sediment may be necessary. This is an expensive maintenance activity and the need for it can be minimized through prevention of upstream erosion. ■ If bypass capability is available, it may be possible to regain the infiltration rate in the 5 -year maintenance short term by providing an extended dry period. ■ Seed or sod to restore ground cover. ■ Total rehabilitation of the trench should be conducted to maintain storage capacity within Upon failure 2/3 of the design treatment volume and 72 -hour exfiltration rate limit. ■ Trench walls should be excavated to expose clean soil. ■ All of the stone aggregate and filter fabric or media most be removed. Accumulated sediment should be stripped from the trench bottom. At this point the bottom may be scarified or tilled to help induce infiltration. New fabric and clean stone aggregate should be refilled. 2 of 3 California Stormwater BMP Handbook January 2003 Municipal www.catunphandbooks.com E Infiltration Trench TC -10 Additional Information Infiltration practices have historically had a high rate of failure compared to other stormwater management practices. One study conducted in Prince George's County, Maryland (Galli, 1992), revealed that less than half of the infiltration trenches investigated (of about 50) were still functioning properly, and less than one-third still functioned properly after 5 years. Many of these practices, however, did not incorporate advanced pretreatment. By carefully selecting the location and improving the design features of infiltration practices, their performance should improve. It is absolutely critical that settleable particles and floatable organic materials be removed from runoff water before it enters the infiltration trench. The trench will clog and become nonfunctional if excessive particulate matter is allowed to enter the trench.

(LGC) was retained by DBI GROUP (Client) to perform a Phase I Environmental Site Assessment (Phase I ESA or Assessment) of a 4.37 -acre proposed commercial development site located on the south side of Nicolas Road in the City of Temecula, Riverside County, California. At the time of the March 10, 2006 site visit, the subject property consisted of 4.37 -acres of undeveloped land located within a commercial and residential area of Temecula. This Phase I ESA was. performed in accordance with the scope and limitations of the American Society for Testing and Materials (ASTM) Phase I ESA Standard E1527-00, the scope of work defined in this report, as well as the signed service agreement. The following summarizes LGC's independent conclusions and best professional judgment based upon information available to us during the course of this Assessment. Based upon the site visit, historical review, regulatory records review, and other information detailed within this report, this Assessment identified no evidence of ASTM Recognized Environmental Conditions (RECs) in connection with the subject property. However, other non -RFC issues were identified: e The subject site was formerly maintained as pasture land. A review of historical aerial photographs with coverage of the subject property identified a pasture land use from at least 1949 through at least 1980. The former use of the subject property as pastae land does not appear to be a significant environmental concern and no further action is recommended at this time in regards to the previous pastae land use of the subject property. The subject property has been undeveloped from 1983 to the present. e An ARCO gas station adjoins the subject property to the west at 40212 Winchester Road. The ARCO site ( • is listed in the EDR database report as a small quantity generator and an active UST site with no violations found or reported releases. LGC has submitted a records request to the Riverside County Department of Environmental Health (RCDEH) for the ARCO facility. If any significant environmental issues are identified in RCDEH records that are returned to LGC, LGC will issue an addendum to this report. e Several stockpiles of soil with trash were observed at the subject property in the southwest portion of the subject property. One abandoned tire and several small abandoned piles of construction debris were observed along the southern boundary of the subject property. A used tire located on-site should be recycled or properly disposed oraccording to current regulations. e No dry cleaners, gasoline stations, landfills, military bases or major manufacturing businesses were identified on the subject property. No evidence of significantly improper hazardous waste disposal was observed on the subject property in accessible areas. No significant staining or spillage was noted at the subject property, No mines or wells were noted in the immediate area of the subject property. During the site visit, no stained or discolored sinks, drains, catch basins, drip pads, or sumps were observed on the subject property. Based upon LGC's site visit and historical research results, it appears unlikely that USTs or hazardous materials incidents have occurred at the subject property, An Executive Summary Overview is also included on the previous page. However, when making any decisions concerning the findings of this Assessment, please also refer to the remainder of this report, which may present other items of interest that are not discussed in the Executive Summary, and/or provide further detail concerning the above -listed items. ro 2.0 SCOPE OF WORK & LIMITATIONS 2.1 Purpose The primary goal of this Phase I Environmental Site Assessment is to assist the client in satisfying one of the four requirements to qualify for the "innocent landowner defense" to CERCLA liability (42 U.S.C. § 9601 et. seq.). The innocent landowner defense is predicated on the assumption that "...the defendant must have undertaken, at the time of acquisition, all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or, customary practice in an effort to minimize liability...." The secondary goal of this Assessment is to provide information that will assist in evaluating the risk of potential value impairment of the security interest or environmental liability, as well as to provide information for various potential operational limitations and decisions based, upon those potential defects. 2.1 Protocol The ASTM Standard E1527-00 is the most widely recognized method currently used in attempting to perform the due diligence required to achieve the above purpose. The E1527-00 Standard was created by the ASTM "...in an effort to define good commercial and customary practice in the United States of America for conducting an environmental site assessment...." The ASTM Standard E1527-00 is intended to identify recognized environmental conditions (RECs) in connection with a given property. The teen recognized environmental conditions is not intended to include "de minimus" conditions that generally do not present a material risk of harm or that are unlikely to be the subject of enforcement actions by governmental agencies. Other conditions or issues that are beyond the ASTM scope may also be discussed in this repot, as detailed within each section. 2.3 Scope of Work Utilizing ASTM Standard E1527-00, as well as the scope of work discussed below and in the work authorization document, this Assessment involved: A site reconnaissance of the subject property, limited observations of adjoining properties, a review of the historical usage of the subject property, and a review of relevant documentation provided by various public and private sources (including the client and/or owner of the subject property) to evaluate the presence or likely existence of: ♦ Recognized environmental conditions, specified by ASTM E1527-00 as: "the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, groundwater or surface water of the property." s A brief evaluation and assessment of pot6tial environmental issues which may not rise to the level of recognized environmental conditions, such as: obviously improper hazardous material or waste handling, off-site issues, suspect asbestos -containing materials, lead-based paint, polychlorinated bi-phenyls, and radon gas. Project No. E061305-40 Page 2 March 22, 2006 (t --*2.4 Limitations As discussed in ASTM E1527-00, no Phase I ESA can completely eliminate uncertainty regarding the potential for RECs in connection with a subject property. This investigation is simply intended to reduce uncertainty within reasonable limits of time and cost. Refer to Section VI -A for a brief discussion of some (but not necessarily all) specific limitations to LGC's subject property observations at the time of the site visit. The observations contained within this Assessment are based upon conditions readily observable during the site visit. These observations are typically unable to address conditions of areas not inspected, areas hidden from view, subsurface soil, groundwater, underground storage tanks, neighboring properties, and the like, unless specifically mentioned. It is not the purpose of this Assessment to determine the actual presence, or degree or extent of contamination (if any) at the subject property. Unless specifically noted within this report; this Assessment does not include observations, testing, coring, or sampling analysis to address groundwater, soil, or extraneous materials contamination (including mold issues) in or on the subject property. This Assessment does not include or address reasonably ascertainable environmental liens recorded against the subject property. LGC makes no warranties or guarantees as to the accuracy or completeness of information obtained from or compiled by others. Information may also exist which was beyond the scope of this investigation, or was not provided to LGC that may have an impact on the conclusions of this Assessment. This Assessment does not attempt to address past or forecast future site conditions. • This Assessment has been conducted and prepared in accordance with generally accepted practices and 1 procedures exercised by reputable professionals under similar circumstances. LGC makes no other warranties or guarantees, either expressed or implied, as to the findings, opinions, or recommendations contained in the report, or as to the existence or non-existence of RECs at the subject property. 3.0 GENERAL SITE DESCRIPTION LGC Inland, Inc. (LGC) was retained by DBI GROUP (Client) to perform a Phase I Environmental Site Assessment (Phase i ESA or Assessment) of a 4.37 -acre proposed commercial development site located on the south side of Nicolas Road in the City of Temecula, Riverside County, California. At the time of the March 10, 2006 site visit, the subject property consisted of 4.37 -acres of undeveloped land located within a mixed commercial and residential area of the City of Temecula. During the site visit, the LGC Assessor was unaccompanied. The subject property was bounded by Nicolas Road to the north, a day care/preschool business to the east, the Roripaugh Hills residential development to the south and commercial businesses including an ARCO gasoline station and a Jack -In -The -Box restaurant to the west. A Riverside County Assessor's Parcel Map (AMI) showing the boundaries of the subject property was provided to LGC by the Client and was used in delineating the subject property boundaries. The APM indicates the subject property includes Assessor's Parcel Numbers 920-100-025, -026, -030 and -032. Project No. E061305-40 Page 3 March 22, 2006 3.1 3.2 (0 3.3 Previous Environmental Documentation The Client has not provided or reported to LGC any information which indicates the subject property is being sold or purchased at a significantly reduced price due to outstanding environmental issues. Nor has the Client provided or reported to LGC information indicating a specific knowledge of RECs, historic RECs or Environmental Deed Restrictions related to the subject property. In addition, no previous environmental documentation (Phase 1 ESAs, Phase II ESAs, etc.) concerning the subject property was provided to LGC or reported to exist by the Client. It is possible information contained in prior reports (if any) could change LGC's conclusions or recommendations herein. If previous environmental documentation becomes available to the Client or subject property owner, a copy should be provided to LGC for evaluation. Ad oinine and Adjacent Properties As discussed in ASTM El 527-00, an adjoining property is any real property whose border is contiguous or partially contiguous with the subject property, or would be if the properties were not separated by a roadway, street or other public thoroughfare. For the purposes of this report, an adjacent property is any real property located within approximately one block of the subject property's border. The subject property is located within a commercial and residential area. Specifically, the subject property is bordered by the following: North: Immediately by Nicolas Road followed by land being developed for a shopping center with a Neighborhood Commercial zoning. East: Immediately by Childtime (a daycare/preschool) followed by a Roripaugh Hills recreation complex, then by Roripaugh Road and the Roripaugh Hills residential development. South: Immediately and further by the Roripaugh Hills residential development. West: Immediately by an Arco Minimart-gasoline station and a Jack -In -The -Bax restaurant, then by Winchester Road followed by Chaparral High School. USGS Topoeraphic Map The subject property's physical setting was researched employing a United States Geological Survey (USGS) 7.5 Minute Topographic Quadrangle (Qtuad) Map relevant to the subject property. The USGS 7.5 Minute Quad Map has an approximate scale of 1 inch to 2,000 feet, and shows physical features such as wetlands, roadways, mines, and buildings. The USGS 7.5 Minute Quad Map was used as the Standard Physical Setting Source, and is sufficient as a single reference. Project No. E061305-40 Page 4 March 22, 2006 The subject property is located on the Murrieta 7.5 -minute Quadrangle Map (dated 1953, photorevised 1979). This map shows no physical features on-site that are likely to environmentally impact the subject property. The subject property is identified as undeveloped land with Nicolas Road immediately adjoining the subject property to the north. No on-site structures are depicted. The elevation of the subject property generally ranges from approximately 1,086 feet above mean sea level (AMSL) at the southwesterly corner to approximately 1,115 feet AMSL at the northeasterly corner, with an overall topographic gradient to the southwest. A small structure is depicted on a nearby property to the west. No mines, wells, aboveground storage tanks or wetlands were identified in the immediate area of the subject property. However, a small reservoir is noted to the east of the subject property. This map is included in the appendix as Figure 1. In addition, LGC reviewed one historical topographic map of the subject property area. That review revealed the following: 1953: The subject property is identified as undeveloped land with no visible roads adjoining the property. No on-site structures are depicted. A few small structures (likely dwellings) are depicted less than '/z -mile north and east of the subject property. No mines, wells, aboveground storage tanks, or wetlands were identified in the immediate area of the subject property. However, two reservoirs are noted to the south and east of the subject property. 3.4 General Hve1rof,eo1ot;ic Characteristics Regionally, the site is located in the Peninsular Ranges Geomorphic Province of California. The Peninsular Ranges, are characterized by steep, elongated valleys that trend west to northwest. The I, • northwest -trending topography is controlled by the Elsinore fault zone, which extends from the San Gabriel River Valley southeasterly to the United States/Mexico border. The Santa Ana Mountains lie along the western side of the Elsinore fault zone, while the Perris Block is located along the eastern side of the fault zone. The mountainous regions are underlain by Pre -Cretaceous, metasedimentary and metavolcanic rocks and Cretaceous plutonic rocks of the Southern California Batholith. Tertiary and Quaternary rocks are generally comprised of non -marine sediments consisting of sandstone, mudstones, conglomerates, and occasional volcanic units. The geologic structure of the Southern California area is dominated by northwest -trending faults associated with the San Andreas Fault system. Faults, such as the Newport -Inglewood, Whittier - Elsinore, San Jacinto and San Andreas are major faults in this system and all are known to be active. In addition, the San Andreas, Elsinore, and San Jacinto Faults are known to have ruptured the ground surface in historic times. The surficial soil underlying the area of the subject property has been characterized as: Hanford-Tujunga-Greenfield association — consists of very deep, well -drained to excessively drained, nearly level to moderately steep soils that have a surface layer of sand to sandy loam; on alluvial fans and floodplains (source: 1971 USDA -SCS Soil Survey of Western Riverside Area, California). Project No. 6061305-40 Page 5 March 22, 2006 Although site-specific groundwater information for the subject property was unavailable, according to the Western Municipal Water District Cooperative Well Measuring Program (Spring 2005), measurement of a well nearest to the subject property dated April 2005 indicated a depth to groundwater of approximately 295 feet below the ground surface. It is assumed the direction of groundwater flow follows the ground surface patterns toward the west. However, local groundwater can be influenced by several factors, and may not conform to the reported regional pattern. Shallower groundwater zones may also occur. 4.0 HISTORICAL REVIEW The site historical review is used to develop an understanding of the previous uses of the subject property and surrounding area in an effort to identify the likelihood of past uses, or activities having environmentally impacted, the subject property. The historical review consisted of a search of various public and private Standard Historical Sources, as detailed in the sections below. As defined by ASTM E1527-00, a Standard Historical Source is considered complete if the information contained within the source provides the required information back to 1940, or to the first developed use (including aLricultural). Ideally, the information should be available in either five-year intervals or site milestone events (i.e., initial construction activities, demolition activities, etc.). However, available public and private historical sources do not always fulfill this goal, in which case, the closest approximation is made based upon the sources readily available at the time of historical review. •Historical Review Satnmarv: From the historical information review discussed below, LGC concludes that the subject property and surrounding properties have been predominantly dry -farmed pasture land since at least 1949 through at least 1974. From at least 1930 through 2006 the subject property has been graded, undeveloped land. No dry cleaners, gasoline stations, major landfills, military bases, industrial facilities, or major manufacturing businesses were identified on the subject property. The ASTM Standard Practice E-1527-00 standard is to research readily available historical sources to 1940 or prior to the initial development of the subject Property, whichever is earlier. However, ASTM recognizes that data failure can occur. The oldest reasonably ascertainable historical resource available for this report, a 1949 aerial photograph, indicated the subject property had a dry -farmed pasture land use. Data failure occurred because the historical resources utilized in researching the subject property did not provide information for the subject property back to or prior to 1940. However, based on the information obtained from readily available sources, it is unlikely that earlier sources (if available) would affect the conclusions of this report. 4.1 Aerial PhotmZraph Review Aerial photographs were reviewed to evaluate palst land -use patterns of the subject property and vicinity. The photos were provided by the Riverside County Flood Control and Water Conservation District (RCFCWCD). Reproduction of the RCFCWCD photos for publication was not allowed. A data gap of nine (9) years exists for the subject property because aerial photos were available only from 1949 onward from the RCFCWCD. This review revealed the following: 0 Project No. E061305-40 Page 6 March 22, 2006 1949: The subject property is pasture land. Roads, structures or other development were not visible on-site. The surrounding land usage also consists of pasture land and agricultural land. Notch: pasture land with no visible roads followed by the Santa Gertrudis Creek, then undeveloped land. East: agricultural land with one rural residence followed by undeveloped land. South: natural vegetation then undeveloped land wifh no visible roads in the vicinity. West: agricultural land with a rural residence followed by a road then agricultural land followed by Santa Gertrudis Creek. 1962: Conditions at the subject property appear similar to those observed in the 1949 aerial photograph. Banana Avenue (now Winchester Road) is visible to the west of the subject property. Conditions at the adjoining properties appear similar to those observed in the 1949 aerial photograph, with the exception that an outbuilding is associated with the [ural residence to the northeast. Several structures (likely dwellings and outbuildings) are located to the north of the subject property. 1974: This aerial photograph is similar to the 1962 aerial photograph except the hill to the south of the subject property has been disced with unimproved roads treading northeast/southwest and has also been developed with a residential dwelling. The property to the east has roads crisscrossing for a development that has not been built. 1980: The subject property is disced undeveloped land with Nicolas Road on the northern boundary and an unimproved road along the southern boundary. North: pasture land followed by Santa Gertrudis Creek then a residence with outbuildings followed by • undeveloped land. East: unimproved road followed by disced undeveloped land. South: undeveloped hill crisscrossed by unimproved roads and a dwelling. West: disced undeveloped land followed by two lane road then disced land followed by Santa Gertrudis Creek. 1983: This aerial photograph is similar to the 1980 aerial photograph except scattered trees exist along Nicolas Road and on the southern property boundary. The surrounding properties are similar to those observed in the 1980 aerial photograph except that development is increasing with additional houses to the southeast and to the south. A teardrop shaped area on the hill to the south is visible and appears to be a lawn area with trees. 1990: This aerial photograph is similar to the 1983 aerial photograph with the exception that residential housing tracts have been developed to the east, south and west. 1995: This aerial photograph is similar to the 1990 aerial photograph with the exception that the Chaparral High School across Winchester Road to the west is being developed. 2000: This aerial photograph is similar to the 1995 aerial photograph with the exception that the western adjoining property has been developed with an Arco gasoline station and a Jack -In -The -Box restaurant and further beyond Winchester Road the Chaparral High School has been completed. Projecl No. E061305-40 Page 7 Mai -ch 22, 2006 2005: This aerial photograph is similar to the conditions observed during the site visit. The Childtime daycare/preschool has been developed to the east of the subject property. 4.2 Building Permit Review In an effort to evaluate the official construction and demolition history (if any) of the subject property, LGC attempted to request all building permits on file with the Riverside County Department of Building and Safety. However, according to the Riverside County Department of Building and Safety, the subject parcels had no building permits issued. Additionally, LGC attempted to request all building permits on file with the City of Temecula Building and Safety Department. According to the City of Temecula Building and Safety Department, the subject parcels had no building permits issued. 4.3 Sanborn Fire Insurance Man Review LGC attempted to review Sanborn Fire Insurance Maps for the area of the subject property as provided by EDR. Sanborn Maps are detailed drawings that show the location and use of structures on a given property during specific years. These maps were originally utilized by insurance companies to assess fire risk, but are now utilized as a valuable source of historical and environmental -tisk information. However, according to EDR, no maps were available for the area of the subject property. 4.4 City Street Directorp Review Based upon the other significant historical sources available, the confirmed current and previous • undeveloped site usage, and a lack of street addresses for the subject property, city street directories were \— not reviewed. 4.5 Interviews A copy of an Environmental Site Assessment Key Site Manager (KSM) Questionnaire was sent via the mail to the property owners listed in the Riverside County Tax Assessor records, Leo E. Roripaugh and June R. Tull. To date, the KSM Questionnaires have not been returned to LGC. 4.6 Recorded Land Title Records As specified in ASTM E 1527-00, recorded land titles are records usually maintained by the municipal or county recorder of deeds which detail ownership fees, leases, land contracts, easements, and other encumbrances attached to or recorded against the subject property. Due to state land trust regulations and laws, land -title records typically only provide trust names, owners names, or easement holders, and not information concerning previous uses or occupants of the subject property. Additionally, environmental liens recorded against a given property are considered outside the scope of recorded land - title records. Therefore, this Assessment has relied upon other standard historical information sources which are typically more informative than recorded land titles. In, addition, the Client has not provided recorded historical [and title records for LGC's review. l� Project No. E061305-40 Page 8 March 22, 2006 l• 5.0 AGENCY RECORDS REVIEIV In an effort to evaluate whether the subject property or nearby sites have reported USTS, hazardous waste generation, or hazardous material releases, regulatory information from the federal, state and local agencies listed below were reviewed. The database review was provided by Environmental Data Resources, Inc. (EDR) and is reportedly the most recent database information available fi•om each agency. A copy of the database report is included in the appendix. In addition, LGC may request state or local agency regulatory information for the subject property, targeting those agencies most likely to provide information useful for this Assessment. A discussion of the number of sites identified, and of their potential impact to the subject property, is detailed on the following pages.

The RCRIS generator facilities database (large and small quantity generators) is the composite of reporting facilities that generate hazardous waste. Small quantity generators (SQGs) generate between'] 00 kg and 1,000 kg of hazardous waste per month. Identification on this list does not indicate that a site has impacted the environment. A search of the RCRIS facilities database identified the following number of sites within the specified database search range: NUMBER OF SITES NUMBER LISTED AT SUBJECT PROPERTY One (1). None - One (1) site is listed as a small quantity generator (SQG) adjoining the subject property. This site has no violations reported. ARCO #6305 is located adjoining the subject property to the west at 40212 Winchester Road. Based upon its status (no violations found), this site is unlikely to have environmentally impacted the subject property. RCRIS Corrective Action (CORRACTS) Sites: The CORRACTS report contains information pertaining to facilities which have conducted, or are currently conducting corrective actions as regulated by the Resource Conservation and Recovery Act.

Tomra Pacific Inc./Albertsons #6734 is located to the northwest of the subject property at 39140 Winchester Road and recycles aluminum, glass and plastic containers and became operational on June 22, 2005. Based upon its distance and elevation position, this site is unlikely to have environmentally impacted the subject property. Project No. E061305-40 Page 12 March 22, 2006 U • Underground Storage Tanks (US7s): USTs are regulated under Subtitle I of the RCRA, and must be registered with the State Underground Storage Tank Program. These are registered USTs only, and identification on this list does not necessarily indicate that the site has impacted the environment. A search of the UST database identified the following number of sites within the specified search range: NUMBER. SITES NUMBER LISTED AT SUBJECT PROPERTY Two (2) 1 None These UST sites adjoin the ,subject property to the west at 40212 Winchester Road (ARCO #6305) while an Albertsons Express #6734 is located over 1/8 -mile northwest of the subject property. The Albertson's Express #6734 located at 39224 Winchester Road is listed on the Riverside County UST list as having two (2) tanks and has no reported releases. The ARCO gas station is listed twice and is also listed in the FINDS database. The ARCO facility has four (4) USTs and no reported releases. There was no indication of soil boring locations at the ARCO facility and no groundwater monitoring wells were observed adjoining the subject property to the west. There were four (4) vent pipes observed and two locked hazardous waste solids drums adjoining the subject property to the west at the ARCO facility. The drums were not leaking and were secured behind a locked chain-link fence. LGC has submitted a records request to the Riverside Comity Department of Environmental Health (RCDEH) for the ARCO facility. If any significant environmental issues are identified in RCDEH records that are returned to LGC, LGC will issue an addendum to this report. RCDEH records normally take several weeks to be delivered. Based on the relatively new construction age of the adjoining ARCO facility that includes secondary containment and vapor recovery technology, the lack of any reported releases, soil boring locations or observed groundwater monitoring well locations, and the fact that the four (4) ARCO USTs are located approximately 145 feet west of the subject property, the ARCO gas station facility does not appear to have environmentally impacted the subject property. Due to the distance of the Albertson's Express #6734 from the subject property and the lack of any reported releases, it does not appear to have environmentally impacted the subject property. California Facility Index Database (CA PH)). The Facility Index Database contains active and inactive underground storage tank locations. The source is the State Water Resources Control Board. Identification on this list does not necessarily indicate that the site has impacted the environment.

Thessalonika Family Services — Unit 3 was listed as having a current status of "No Action — For Calmortgage Only". DTSC comments stated that "Pursuant to the MOU, DTSC has prepared a Phase I Environmental Assessment for Thessalonika Family Services (TFS). This property contains a single-family home that is currently being used by TFS as a youth group home/residential treatment facility. No change in use is proposed. A Phase I Report was prepared by DTSC and concluded that no action was needed for this property; there is no contamination on the property." Based upon its distance and status, this site is unlikely to have envirommentally impacted the subject property. Project No. E061305-40 Page 14 Mach 22, 2006 HAZNETDatabase (HAZNET).- HAZNET HAZNET): HAZNET data is extracted from copies of hazardous waste manifests received each year by the Department of Toxic Substances Control (DTSC). These manifests track hazardous wastes from generation source to the point of ultimate disposal. Permit data is generally culled from the local agency database for hazardous material handlers and generators. Identification on these lists does not indicate that a site has impacted the environment and the data has not always been verified for accuracy by the DTSC or local agencies. A search of the HAZNET data identified the following number of reported sites within the specified database search range: NUMBER OF SITES NUMBER LISTED AT SUBJECT PROPERTY One (3) - None One (1) site is listed in the HAZNET database adjoining the subject property. ARCO #6305 is located adjoining the subject property to the west at 40212 Winchester Road, The ARCO facility disposed of 0.17 tons of organic solids and recycled 1.66 tons of aqueous solution with less than 10% total organic residues. Based upon the disposal and recycling of the identified wastes, this site is unlikely to have environmentally impacted the subject property. Orphan Unplottable Sites: "Orphan" sites are those which could not be plotted by EDR using conventional geo-coding methods, typically because the information provided in the original government database was unclear, incorrect or • missing. A listing of orphan sites (if any) appears at the end of the EDR database, immediately after the last plottable site description. LGC reviewed the orphan list for sites with the same name as the subject property (if applicable) and/or the same or similar property address. This review is inherently limited by the incomplete and/or possibly incorrect data reported in the orphan listings. For orphans apparently not related to the subject property, only those obviously located adjoining or within a short distance that may affect the property are discussed. Orphan sites which are also listed in the plotted section are not re -discussed. LGC's review of the orphan list revealed no obvious sites of concern listed at or adjoining the subject property. 5.3 Load Agency Records Search The following is a discussion of the results of written records requests LGC made to state or local government agencies and/or personal/telephone contacts made to provide information relevant to the subject property: Rlrerside County Department of Environmental Health (RCDEH): LGC contacted the RCDEH in an effort to evaluate whether hazardous material incidents or USTs have been reported at the subject property. According to the RCDEH, no environmental cases were reported for the subject property parcels. LGC has submitted a records request to the RCDEH for the ARCO facility. If any significant environmental issues are identified in RCDEH records that are returned to LGC, LGC will issue an addendum to this report. RCDEH records normally take several weeks to be delivered. Additionally, based upon LGC's site visit and historical research results, it appears unlikely that USTs or hazardous materials incidents have occurred at the subject property. Project No. E061305-40 Page 15 March 22, 2006 (70 City of Temecula Code Enforcement Department: LGC contacted the City of Temecula Code Enforcement Department in an effort to evaluate whether hazardous material incidents or USTs have been reported at the subject property. According to the City of Temecula Code Enforcement Department, no environmental cases were reported for the subject property parcels. 6.0 SITE VISITS OBSERVATIONS 6.1 Surface Characteristics At the time of the site visit, the subject property consisted of 4.37 -acres of undeveloped land consisting of four (4) tax parcels. The majority of the subject property surface area was disced with a sparse cover of natural weeds/grasses and Pampas Grass along the southern boundary. Obvious signs of unnatural or chemically induced stress to the vegetation growth were not observed at the time of the site visit. Springs, permanent streams, or other surface waters were not observed; however, several puddles were observed from recent rains, primarily on the northern side of the subject property. Pits, ponds, lagoons, or surface impoundments potentially containing hazardous materials were not observed on the subject property. Weather conditions at the time of the site visit consisted of cloudy skies, with temperatures in the SOs. Water supply wells or related water storage tanks were not observed on the subject property. (' • Additionally, buildings, dwellings, outbuildings (garages, sheds, etc.), or indicators of such past structures (foundations, etc.) were not observed. Several dirt stockpiles with trash were observed in one subject property location (the southwestern portion of the site). One abandoned tire and several piles of construction debris were observed on the southern boundary of the subject property site. However, no spills, staining or other obvious or significant hazardous waste dumping was noted on or around these debris piles at the time of the site visit. The visible surfaces of the subject property appeared to be in good condition with no significant signs of chemical dumping or spillage, although a "de minimus" (4 foot by 1 foot) area of soil staining was observed. Service trucks and tractor -trailers frequently park on the western boundary of the subject site and were observed at the time of the site visit. 6.2. Wastewater and Storunvater Management Indicators of wastewater generation were not observed on-site. Exterior storm waters u rface run-off from the subject property is expected to infiltrate through the site soils, as well as flow into an exterior stormwater drain observed in the northwest portion of the subject property. 6.3 Potable Water Supply And Server Service The subject property is undeveloped and potable water supply and sewer service connections were not observed on the subject property, however, utility manhole covers were observed in the northerly and westerly adjoining roadways. Upon future development, the subject property will likely utilize water and sewer service supplied by the Rancho California Water District. In addition, no water supply wells were observed on-site. • Project No. E061305-40 Page 16 March 22. 2006 �•6.4 Structure Construction On-site structures or evidence of past structures were not observed on the subject property. 6.5 Business Operations Description At the time of the site visit, the subject property consisted of 4.37 -acres of undeveloped land. According to the City of Temecula, the subject property is zoned Neighborhood Commercial. LGC's research indicates no dry cleaners, gasoline stations, landfills, military bases, or major manufacturing operations have occupied the subject property. 70 HAZARDOUSMATERIAG/WASTEOBSERVATIONS 7.I Hazardous Materials Handling And Storage During the site visit, no significant hazardous materials handling, storage, or disposal issues were observed on the subject property. In addition, no major hazardous material staining or spillage was noted in any of the observable exterior areas. 7.2 Wastestream Generation, Storage And Disposal Indicators of significantly improper hazardous waste disposal (landfilling open disposal pits, etc.) were not observed on the subject property dining the site visit. Additionally, stained or discolored sinks, • drains, catch basins, drip pads, or sumps were not observed. 7.3 Solid Waste Disposal Municipal waste dumpsters were not observed at the subject property during the site visit. However, several piles of construction debris, dirt stockpiles and an abandoned used tire were observed in various areas on the subject property. Obvious indicators of significant hazardous material dumping were not observed in the visible areas in and around these abandoned debris/trash piles. When these trash piles and other debris are removed, care should be taken to look for potential obscured hazardous materials within the piles (if any). 7.4 Aboveground Storage Tanks (ISTS) Visual or physical indicators of cun-ent or former ASTs were not observed at the subject property during the site visit. Project No. E061305-40 Page 17 March 22, 2006 (=/.5 Underground Storage Tanks (USTs) As discussed in the Section V (Agency Records Review) of this report, USTs were not repotted at the subject property. In addition, visual or physical indicators of current or former USTs were not discovered during the site visit. in particular, LGC searched for: fill pipes, vent pipes, manways, manholes, access covers, and concrete pads not homogeneous with surrounding surfaces, concrete build- up areas potentially indicating pump islands, abandoned pumping equipment, or fuel pumps. 8.0 OTHER POTENTIAL ISSUES OF CONCERN 8.1 PCS-Containine Exteriot-Electr•ical TransIbviners One (1) pole -mounted, utility -owned electrical transformer was observed at the subject property on the northwestern boundary of the subject property. This transformer appeared to be in good condition, showing no signs of damage or past leakage, and based on visible labeling, was owned by the Southern California Edison Company (SCE). it is possible that it contains poly -chlorinated biphenyls (PCBs). However, regardless of the PCB content, the maintenance, repair, or replacement of the transformer is the responsibility of SCE, and therefore, no further investigation regarding the on-site transformer is recommended. 8.2 Other PCB -Containing Interior Or Exterior Equipment • Evidence of other equipment potentially containing PCB -contaminated fluid was not observed during the site visit. 8.3 Suspect Asbestos-ContainingMaterials (ACWs) Structures were not observed during the site visit; therefore, suspect asbestos -containing materials (ACMs) are not a significant environmental concern for the subject property. 8.4 Lead Based Paint (LBP) Structures were not observed during the site visit; therefore, suspect lead-based paint (LBP) materials are not a significant environmental concern for the subject property. 8.5 Lead in Drinking Water Structures with active water systems were not obsgrved during the site visit. 8.6 Air Ouality Unusual smells, odors, or visual emissions were not observed during the site visit. However, these observations are general in nature and should not be construed as an air quality assessment. Project No. E061305-40 Page 18 March 22, 2006 �8.7 Radon According to the USEPA, the general area of the site has a Radon Zone Level of 2, which has a predicted average indoor screening level of between 2.0 picoCuries per liter of air (pCi/L) and 4.0 pCi/L. This level is below the EPA action level of 4.0 pCi/L. Therefore, based upon the reported subsurface characteristics of the area, the subject property exhibits a low potential for radon exposure. 8.8 Railroad Rights -of -Wap Railroad rights-of-way were not observed or identified on or adjoining the subject property. 9.0 ADJOINING PROPERTY OBSER VATIOA'S As discussed below, based upon limited observations of the adjoining properties from publicly accessible locations, as well as a review of federal, state, and local environmental databases, none of the adjoining properties appeared to have environmentally impacted the subject property. 9.1 Adjoining- PropertiesAlaterialsStorage Visual observations of the publicly accessible portions of the adjoining properties indicated that hazardous materials or wastes are stored or accumulated at the adjoining property to the west (Arco gasoline station). The ARCO facility has four (4) USTs and no reported releases. There was no indication of soil boring locations at the ARCO facility and no groundwater monitoring wells were i• observed adjoining the subject property to the west. There were four (4) vent pipes observed and two locked hazardous waste solids drums adjoining the subject property to the west at the ARCO facility. The drums were not leaking and were secured behind a locked chain-link fence. LGC has submitted a records request to the RCDEH for the ARCO facility. If any significant environmental issues are identified in RCDEH records that are returned to LGC, LGC will issue an addendum to this report. RCDEH records normally take several weeks to be delivered. Based on the relatively new construction age of the adjoining ARCO facility that includes secondary containment and vapor recovery technology, the lack of any reported releases, soil boring locations or observed groundwater monitoring well locations, and the fact that the four (4) ARCO USTs are located approximately 145 feet west of the subject property, the ARCO gas station facility does not appear to have environmentally impacted the subject property. No indications of spillage or staining were noted in the observable exterior areas of this site. Additionally, no obvious indications of improper hazardous material storage or unusual or suspicious materials handling or storage practices were observed. 9.2 Adjoining Properties Wastestream Disposal Unusual or suspicious wastestream disposal activities were not observed on the portions of the adjoining properties visible from the subject property or public roadways.

Elevations have been determined from the USGS Digital Elevation Model and should beevaluated on a relative (not an absolute) basis. Relative elevation information between sites of. close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property. Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed. Sites listed in bold italics are in multipfe databases. Unmappable (orphan) sites are not considered in the foregoing analysis. FEDERALRECORDS RCRAInfo: RCRAInfo is EPA's comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act ( RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. RCRAInfo replaces the data recording and reporting abilities or the Resource Conservation and Recovery Information System(RCRIS). The database includes selective information on sites which generate, transport, store , treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Conditionally exempt small quantity generators (CESQGs) generate less than 100 kg of hazardous waste, or less than 1 kg of acutely hazardous waste per month. Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month Large quantity generators generate over 1,000 kilograms (kg) of hazardous waste, or over 1 kg of acutely hazardous waste per month. Transporters are individuals or entities that move hazardous waste from the generator offsite to a facility that can recycle, treat, store, or dispose of the waste. TSDFs treat, store, or dispose of the waste. A review of the RCRA-SQG list, as provided by EDR, and dated 12115/2005 has revealed that there is 1 RCRA-SQG site within approximately 025 miles of the target property.

The land use restrictions on this list were required by the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed restriction, or a land use restriction that binds current and future owners.

Manufactured gas sites were used in the United States from the 1800's to 1950's to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.
