Pollutants of Concern • Potential pollutants associated with Urban Runoff from the proposed project must be identified. Exhibit B of the WQMP provides brief descriptions of typical pollutants associated with Urban Runoff and a table that associates typical potential pollutants with types of development ((and 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: I. 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/tmdU303d_lists.html. List all pollutants for which the proximate Receiving Waters are impaired. • 3. Compare the list of pollutants for which the proximate Receiving Waters are impaired with the pollutants expected to be generated by the project. Urban Runoff Pollutants: POLLUTANTS EXPECTED POTENTIAL POTENTIAL SOURCE 303 d LISTING SEDIMENTITURBIDITY X ROOF/LANDSCAPE NUTRIENTS X LANDSCAPE X ORGANIC COMPOUNDS X ROOF/LANDS CAPE TRASH & DEBRIS X CUSTOMER/RESIDENT/ EMPLOYEE OXYGEN DEMANDING SUBSTANCES X LANDSCAPE PATHOGENS ( BACTERIA & VIRUSES) X GARBAGE/ROOF OILS & GREASE X RESTAURANT PESTICIDES X LANDSCAPE METALS X ROOF DRAIN X -5- Water Quality Management Plan (WQMP) PERKINS MIXED USE BUILDING • POLLUTANTS OF CONCERN: Phosphorus, Nitrogen, Iron, and Manganese are the pollutant of concern, since this site runoff will discharge into Murrieta Creek, and Murrieta Creek is listed on the 2006 303(d) list as impaired for these pollutants of concern. • LEGACY POLLUTANTS: The project site has two existing commercial buildings with an asphalt parking lot. No known hazardous substances have been used on the property. 20 Water Quality Management Plan (WQMP) PERKINS MIXED USE BUILDING 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 is met: Condition A: Runoff from the Project is discharged directly to a publicly -owned, operated and maintained MS4; the discharge is in full compliance with Co -Permittee requirements for connections and discharges to the MS4 (including both quality and quantity requirements); the discharge would not significantly impact stream habitat in proximate Receiving Waters; and the discharge is authorized by the Co -Permittee. Condition B: The project disturbs less than 1 acre. The disturbed area calculation should include all disturbances associated with larger plans of development. Condition C: The project's runoff flow rate, volume, velocity and duration for the post -development condition do not exceed the pre -development condition for the 2 -year, 24-hour and 10 -year 24-hour rainfall events. This condition can be achieved by minimizing impervious area on a site and • incorporating other site -design concepts that mimic pre -development conditions. This condition must be substantiated by hydrologic modeling methods acceptable to the Co -Permittee. • This Project meets Condition B at 0.27 acres, and is therefore exempt from addressing downstream hydrologic Conditions of Concern. Supporting engineering studies, calculations, and reports are included in Appendix C.

Best Management Practices V.1 SITE DESIGN BMPS Project proponents shall implement Site Design concepts that achieve each of the following: I) Minimize Urban Runoff 2) Minimize Impervious Footprint 3) Conserve Natural Areas 4) Minimize Directly Connected Impervious Areas (DCIAs) The project proponent should identify the specific BMPS implemented to achieve each Site Design concept and provide a brief explanation for those Site Design concepts considered not applicable. Complete Table 1, Then insert text —provide narrative describing which site design concepts were incorporated into the project plans. If the project proponent implements a Co -Permittee approved alternative or equally effective Site Design BMP not specifically described below, the appropriate check box Site Design BMP checkbox should be marked and an additional description indicating the nature of the BMP and how it addresses the Site Design concept should be provided. Note, the Co -Permittees general plan or other land use regulations/documents may require several measures that are effectively site design BMPS (such as minimization of directly connected impervious areas and/or setbacks from natural stream courses). The Project Proponent should work with Co -Permittee staff to determine if those requirements may be interpreted as site design BMPS for use in this table/narrative. See Section 4.5.1 of the WQMP for additional guidance on Site Design BMPS. • If a particular Site Design BMP concept is found to be not applicable, please provide a brief explanation as to why the concept cannot be implemented. Also provide a narrative describing how each included BMP will be implemented. In those areas, where Site Design BMPs require ongoing maintenance, the inspection and maintenance frequency, the inspection criteria, and the entity or party responsible for implementation, maintenance, and/or inspection shall be described. The location of each Site Design BMP must also be shown on the WQMP Site Plan included in Appendix B. • This Project is 0.27 acres, therefore meets Condition B and is exempt from addressing hydrologic Conditions of Concern. Walkways will be a minimum width allowed by the City. 2. Project includes "Contech 2 Cartridge Stormfilter" which will collect roof drain storm flows. PROPOSED PROJECT BMPS MAINTENANCE The. BMP's will be implemented by the project developer prior to receiving certificate of Completion/occupancy. Maintenance and Inspection will be the responsibility of the Property Manager prior to the rental of any units. Inspection for all BMPS proposed will be conducted quarterly and after each major rain storm. Rental Agreement will describe maintenance and inspection schedule. -8- • • Water Quality Management Plan (WQMP) PERKINS MIXED USE BUILDING TABLE 1.

I s R 9 1.2 Location and Site Dewriydon 16 The subject site is located on the northeast corner at the intersection of Old Town Front Street and 5's Stied in the City of Temecula of Riverside County, California_ The general location of the site is shown on the Site location Map (Figure 1). The topography of the site is relatively flat. The general elevation of the property is 1008 feet above mean sea level (rnsl) with differences of less than 2t feet across the entire site. Local drainage is generally directed to the west- No estNo underground structures arc known to exist at the site. The property contains one (1) commercial building that is being used as an antique store. The existing building will be demolished prior to construction of the proposed building. Vegetation consists of a sparse cover of annual weedsigrasces and a few large trees parallel to Old Town Front Strut. Tbc site boundaries include Old Town Front Street to the southwest, 51" Street to the northwest, an alley to the southeast and an undeveloped parking lot to the north 13 Propossd Depelopnrent and Gradinr The proposed oomrnercial development is expected to consist of one steel framed four story building. Formal plans have not been prepared and await the conclusions and recommendations of this report - The plans you provided were utilized in our investigation and form the base for our Geotechnical Map 6 (Plate 1). Since the site has neva been rough graded and due to the elevations of the existing development to the north, LGC assumes that existing grade elevations will remain essentially unchanged. Proposed cut and fill slopes should be less than 5 fed in height. ZO INVES77GA7I0NAND LABORATORY TESTING Z Frdd Invesdration Subsurftcz exploration within the subject site was performed on August 1, 2006 for the exploratory borings. A hollow-sttm-auger drill rig was utilized to drill three (3) borings throughout the site to depths ranging from 26% to 51 feet. Prior to the subsurface work, an underground utilities clearance was obtained from Underground Service Alert of Southern California. IF AT H 8 Earth materials encountered dining exploration were classified and logged in general accordance with the Visual -Manual Soils Descriptions and Identification procedcucs of ASTM D 2488. Upon completion of laboratory testing, sample descriptions were reconciled to reflect laboratory testing utilizing ASTM D 2487. The approximate exploration locations are shown on Plate 1 and descriptive logs are presented in Appendix B. Associated with the subsurface exploration was the collection of bulk (disturbed) samples and relatively undisturbed samples of soil materials for laboratory testing_ The relatively undisturbed samples were obtained with a 3 -inch outside diameter modified California split -spoon sampler lined with 1 -inch high brass rings. in addition, samples were obtained using a Standard Penetration Test (SPT) sampler. The soil samples obtained with the hollow stem auger drill rig, were driven mechanically with successive 30 - Project No. 1061465-10 Page 3 September 7, 2006 t"1 inch drops of an automatic 140 -pound, sampling hammer. The blow count for each six inch increment was recorded in the boring logs. The central portions of the driven samples were placed in scaled containers and transported to our laboratory for testing, 21 Laboratory Te.dnr Maximum dry density/optimum moisture content, expansion potential, R -value, consolidation, resistivity, sulfate content, chloride content, and in-situ density/moisture content were determined for selected undisturbed and bulk samples of soil materials, considered representative of those encounterexd. A brief description of laboratory test criteria and summaries of test data are presented in Appendix C. An evaluation of the test data is reflected throughout the Conclusions and Recommendation section of this report. 23 Atrial Paoropr+aph Interpretation No strong geomorphic lineaments were interpreted to project through the site during our review of aerial photographs of the subject property. Geomorphic evidence of active landsliding was not observed on the site. A table summarizing the aerial photographs utilized in our geomorphic interpretation of lineaments and landslides is included in Appendix A - Aerial Photograph Interpretation Table. 3.0 F LNGS 3.1 Regional GeWagic Sotgnr Regionally, the site is located in the Peninsular Ranges Geomorphic Province of California. The Peninsular Ranges arc characterized by steep. elongated valleys that trend west to northwest The noAhwest-trending topography is controlled by the Elsinore fault zone, which extends from the San Gabriel River Valley southeasterly to the United StatcsIMcxieo 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, mexascdimentary and metavolcanic rocks and Cretaceous plutonic rocks of the Southern California Batholith. Tertiary and Quaternary rocks are generally comprised of nem -matins sediments consisting of sandstone, mudstones, conglomerates, and occasional volcanic units. A map of the regional geology is presented on the Regional Geologic Map, Figure 2. 3.2 Local Geology and Sol! Con&dans The earth materials on the site are primarily comprised of Quaternary older alluvial materials and Quaternary Pauba Formation bedrock A general description of the earth materials observed on the site is provided in the following paragraphs: Quaternary Old Alluvial Flood Plain Deposits (map symbol Ona)- Quaternary old alluvial flood plain deposits were encountered directly from the surface to a maximum depth of 15 feet_ This alluvial unit consists predominately of interboddcd light olive grey to dark brown, fine to medium grained silty sand, fine to coarse grained sand, and sandy silt, silty sand, and clayey sand. This unit is generally moist and loose to medium dense (medium stiff in oonditiom Project No. 1061465-10 Page 4 September 7, 2006 5 O E-11 RI • Quaternary Pauba Formation (may symbol QW: Pauba Formation bedrock was encountered generally at depth below the alluvial materials_ These materials consisted primarily of olive gray to yellow brown, fine to coarse grained sandstone with varying amounts of silt and clay, with occasional interbedded siltstone. These materials were typically moderately hard to hart and slightly moist to very moist. 3.3 Groundrrmrer Groundwater was encountered at a depth of approximately 28 feet in Boring B-2. 3.4 Fontein The geologic structure of the entire Southern California arra is dominated by northwest -trending faults associated with the San Andreas Fault system. Faults, such as the Ncwport-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 Son Jacinto faults are known to have ruptured the ground surface in historic times Based on our review of published and unpublished geologic maps and literature pertaining to the site and regional geology, the closest active fault producing the highest anticipated peak ground acceleration at site is the Elsinore -Temecula Fault located approximately 0.7 kilometers to the southwest This fault is capable of producing a moderate magnitude earthquake. No active faults are known to project through the site and the site does not lie within an Alquist-Priolo Earthquake Fault Zone (previously called an Aklu ist-Priolo Special Studies Zone). 3.5 Ards A -s No landslide debris was noted during our subsurface exploration and no ancient landslides are known to exist on the site. 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 rr rnl From a soils engineering and engineering geologic point of view, the subject property is considered suitable for the proposed development, provided the following conclusions and recommendations arc incorporated into the design criteria and project specifications. dZ Earthwork dZ I General E&r&xnrk and Gradin SareiTca&nns All earthwork and grading should be performed in accordance with all applicable requimnents of the Grading and Fate-rvation Code and the Grading Manual of the appropriate reviewing agency, in addition to the provisions of the 1997 Uniform Building Code (UBC), including Appendix Chapter 33. Grading should also be pcaformed in accordance with applicable provisions of the Genual Earthwork and Grading Specifications (Appendix G), prepared by LGC, unless specifically revised or amended herein. Project No. 1061465- 10 Page h September 7. 2006 v 4.L2 C7emrMandG All weeds, grasses, brush, shntbs, debris and hash in the arras to be graded should be stripped ®• and hauled offsite. During site grading, laborers should clear from fills any roots, branches. and other deleterious materials missed during clearing and grubbing operations. The project geotochnical cnginca or his qualified representative should be notified at appropriate times to provide obsavaum and testing saviees during clearing operaaions and to verify compliance with the above recommendations. In addition, any buried structures or unusual or p adverse soil oonditiom encountered that are not described or anucipated herein should be I brought to the immediate attention of the geotochnical arnsultant. X2..3 ,E,orm�doar t7i . Based on the results of our explormioo. the now surface roil nuftnals, win be readily excavnod r with conventional earth moving oquipmcnt. IP AZ4 I Groundwater was encountered during cur subsurface exploration at a depth of 28 feet. lbaeefore, groundwater is not expected to be a factor during grading or construction. However, localized groundwater could be encountered during construction due to the limited number of exploratory locations or otha factors. I 4as razzid Prepwasifm — M Arman • All existing low density and potentially collapsible soil materiaLs, such us the upper alluvial 1 maserials, and any kosc maa®ade fill, should be removed to underlying competent alluvium, from cacti arca to receive compacted fill. Dense native soils aro subject to verification by the project engines, goologum or their mprnartarive. Prior to placing structural filler the exposed bottom surfaces in each removal area should first be scarified to a depth of 6 inches or more, wateredor air dried as naxssary to achieve Dear -optimum moisture conditions and than m compacted ire -place to a minimum relative compaction of 90 percent. Based on LGC's explwabom znucgxdcd depths of removal we shown on the cockhsed Goota:hnical Map (Plate 1). to general, the anticipated removal depths should vary from 4 to 7 feet- Evaluations of removal depths should be evaluated as a depth of 4' and should eonuaue until sovAbhc removal bottoms arc determinod by our field geologist. However, actual depths and horizontal limits of any removals will have to be determined during grading on the basis of rniptling observabons and testing pefommei by the geotechnical consultant and/or enPmeaM9 geologist. i Projea No. 1(6/465-10 Page 7 September 7. 2006 • 4.1.6 Disposal of Overske Rock Oversize rock is not cxpectod to be encountered during grading. Oversize rock that is encountered (i.e., rock exceeding a maximum dimension of 12 inches) will require special handling, such as offsite disposal or stockpilod onsite and crushed for future use. The disposal of oversirx rock is discussed in General Earthwork and Grading Specifications, Appendix G. 4.2.7 Fill Plaeeweenr Fill materials should be plat ud in b- to 8 -inch maximum (uncompacted) lifts, watered or air dried as nccxssary to achieve uniform near optimum moisture content and then compacted in-place to a minimum of 90 percent relative compaction. The laboratory maximum dry density and optimum moisture content for each soil type should be determined in general accordance with ASTM D 1557-00. 4.1.8 Import Soils for Gradinr In the event import soils arc needed to achieve final dcaign grades, all potential import materials should be free of deleterious/ovcrsizc materials, non -expansive, and approved by the project geotechnical consultant prior to commencement of delivery onsite. 4.29 CaVFdl Transition Lala N Cl To mitigate distress to structures related to the potential adverse affects of excessive differential settlement, cut/fill transitions should be eliminated from all building areas where the depth of fill placed within the "fill" portion exceeds proposed footing depths. The entire structure should be fourxled on a uniform bearing material. This should be accomplished by overcxcavating the -cut" portion and replacing the excavated materials as properly compacted fill- Recommended depths of overexcavation arc provided in the following tabic: DF.PMOFFlitb _. DEPMOFO1VBdeB CAVATMNi-eWPOMMO Up to 5 feet Equal _ 5 to 10 feet 5 fed _ _ Greala than 10 feet One-half the thickness of fill placed on the "fill' portion 10 foci maximum) Ovcrcxcavation of the "cuf' portion should extend beyond the perimeter building lines a horizontal distance equal to the depth of overexcavation or to a minimums distance of 5 feet, whichever is greater. 4.2. 10 Shrinkaee. Bulking and Sub-4drnee Volumetric changes in earth quantities will occur when excavated onsite earth materials are replaced as properly compacted rill. The following is an estimate of shrinkage and bulking factors for the various geologic units found onsite. These estimates are based on in-place densities of the various materials and on the estimated average degree of relative compaction achieved during grading. Project No, 106/465-10 Pa&c F September 7. 1006 r., Subsidence from scarification and recompaction of exposed bottom surfaces in removal areas to rcecivv fill is expected to vary from negligible to approximately 0.1 -foot. The above estimates of shrinkage and subsidence are intended as an aid for project engineers in determining earthwork quantities. However, these estimates should be used with some caudoa since they are not absolute values. Contingencies should be made for balancing earthwork quantities based on actual shrinkage and subsidence that occurs during grading. 4211 GeorechnicalObsmwdons An observation of clearing operations, removal of unsuitable materials, and general grading pnx-.cdures should be performed by the project geotechnical consultant or his representative. Fills should not be placed without prior approval from the gootcchnical consultant. The project geotechnical consultant or his representative should also be present onsite during all grading operations to verify proper placement and adequate compaction of all 511 materials, as j well as to verify compliance with the other recommendations prcsentcd hcr6L 4.3 Post Grading Considtraaionc 43.1 Slone Landscaofnr and Maintenance Adequate slope and pad drainage facilities are essential in the design of the finish grading for the subject site. An anticipated rainfall equivalency of 60 to 100 inches per year at the site can result due to irrigation- The overall stability of graded slopes should not be adversely affected provided all drainage provisions are properly constructed and maintained dwcaRcr and provided all engineered slopes arc landscaped with a deep rooted, drought tolerant and,maintenance free plant species, as recommended by the project landscape architect Additional commeors and recommendations are presented below with respect to slope drainage, landscaping and inigation. A discussion of drainage is given in the following section. 4.3.2 Site DrakM Positive -drainage devices, such as sloping sidewalks, graded swales and/or arca drains, should be provided around buildings to collect and direct all water away from the structures_ Pad drainage should be designed for at least the minimum gradient required by the UBC with drainage directed to the adjacent drainage facilities or other location approved by the building official_ Ground adjacent to foundations shall also be graded at the minimum gradient per the UBC to divert water from foundations. Neither rain nor excess irrigation water should be allowed to collect or pond against building foundations. Roof gutters and downspouts may be required on the sides of buildings where yard-hainagc devices cannot be provided and/or where roof drainage is directed onto adjacent slopes. All drainage should be directed to adjacent driveways, adjacent streets or storm -drain facilities. Proiccl No. 116/465-10 Page 9 Sepfember 7. 2006 4.3.3 005ft Tre�sel6es All utility trench backfill within the street rightof--ways, utility easements, under sedewalks. a• driveways and building -floor slabs, as well as within or in proximity to slopes should be compacted to a minimum relative port on of 90 pereca Where ensde soils are utilized as hack6ll, mechanical compaction will be required. Density testing, along with probing, should be performed by the project geotechnical engineer or their representative to verify proper compaction. For deep trenches with vertical waIK backfill should be placed in approximately 8- to 10 -inch P maximum lifts and then mechanically coerVadod with a hydro-hm=ff- pneumatic tampers OF similar oquiprnent. For deep trenches with sloped walls, backfill materials should be placed in approximately 6- to 8 -inch maximum lifts and then compacted by rvllwg with a shcepsfoat r tamper or similar equipment. Where utility trenches arc prvposod parallel to any building footing (mumor and/or exterior trenches), the bottom of the trench should not be located within a l:l (h --v) plane projected downward from the outside bottom edge of the adjacent footing S.0 susMICOPTICACON90Ei4AAi70NS r 5.1 g Structures to res within the site should be designed and constructed to rust the effects of seismic ground rmotions as provided in the 1997 UBC Sections 1626 through 1633. The method of design is dependent • on the seismic zoning, site characteristics. occupancy category, building configuration, type of structural system and building height. For structural design in accordance with the 1997 UBC, a computer progrmn developed by Thomas F. Blake (USCSEIS, 1998) was used that compiles fault information for a paatiailar site using a modified version of a data file of amoximately 183 California felts that were digitized by the California Division of Minns and Geology and the U.S. Geological Survey. This program computes various information for a particular site, including: the distance of the site &van each of the fao}ts in the data file. the estimated slip rate for cac h (milt and the -maximum moment nurg aitude" of each fault. The program that selects the closest Type A. Type B. and Type C faults from the site and computes the seismic design esr$cients for each of the faadt types. The ptvgam them sdeds the largest of the eemrpwod seismic design coefficients and designates these as the design coefficients for the subject site. The probabilistic seismic hated analysis for the site was completed for three (3) different attenuation relationships (Campbell & Bozorgnia, 1997, Sadigh OR at, 1997, and Abrahamson & Silva, 1997)_ The peak ground acceleration value of 0.81 g is the mean of the three (3) values obtained. The probability of cxceedance versus acceleration waves for the different attenuation relationships are presented in Appendix D. Probability curves were calculated using the computer program FRISKSP version 4.0 (Blake. 2001)).

The working chamber of the FloGarde Downspout Filter is made of a durable dual -wall geotextile fabric liner encapsulating an adsorbent which is easily replaced and provides for flexibility, ease of maintenance and economy. It is designed to collect particulates and debris, as well as metals and petroleum hydrocarbons (oils and greases). As with all FloGarde filters, the FloGarde Downspout Filter performs as an effective filtering device at low flows ("first flush") and, because of the built-in high flow bypass, will not impede the system's maximum design flow. FloGarde Downspout Filters are available in sizes to fit common sizes of downspouts and may be mounted in (recessed) or on (flush) a wall. • FloGarde Downspout Filters are recommended for ultra -urban sites with little to no property area outside of the building perimeter.

The intent of the regulations is to ensure that the systems, on a continuing basis, efficiently remove pollutants from stormwater runoff thereby preventing pollution of the nation's water resources. These Specifications apply to the Flo -Gard TM Downspout Filter. RECOMMENDED FREQUENCY OF SERVICE: Drainage Protection Systems (DPS) recommends that installed Flo-GardrM Downspout Filters be serviced on a recurring basis. Ultimately, the frequency depends on the amount of runoff, pollutant loading and interference from debris (leaves, vegetation, cans, paper, etc.); however, it is recommended that each installation be serviced a minimum of three times per year, with a change of filter medium once per year. DPS technicians are available to do an on-site evaluation, upon request. RECOMMENDED TIMING OF SERVICE: DPS guidelines for the timing of service are as follows: I . For areas with a definite rainy season: Prior to, during and following the rainy season. 2. For areas subject to year-round rainfall: On a recurring basis (at least three times per year). 3. For areas with winter snow and summer rain: Prior to and just after the snow season and during the summer rain season. • 4. For installed devices not subject to the elements (washracks, parking garages, etc.): On a recurring basis (no less than three times per year). SERVICE PROCEDURES: 1. The Downspout Filter shall be visually inspected for defects and possible leakage. Prior to opening, the area around the filter should be protected with waterproof drop cloths extending in at least a 5 -foot radius. 2. The Downspout Filter access door shall be opened, The filter tray shall be carefully pulled out using the handle and set on the floor over a drop cloth. 3. The collected materials in the upper filter shall be inspected, and then removed from the liner using an industrial vacuum or by dumping into an appropriate DOT approved container. 4. When all of the collected materials have been removed from the upper filter, it shall be removed to allow access to the lower filter medium. S. The filter liner, gaskets, stainless steel frame and mounting brackets, etc. shall be inspected for continued serviceability. Minor damage or defects found shall be corrected on -the -spot and a notation made on the Maintenance Record. More extensive deficiencies that affect the efficiency of the filter (tom liner, door gasket damage, etc.), if approved by the customer representative, will be corrected and an invoice submitted to the representative along with the Maintenance Record. 6. The lower filter medium shall be inspected for defects and continued serviceability and replaced as necessary. See below for disposal. 7. The filter components and tray shall be replaced in the housing and the door closed and secured. 0 EXCHANGE AND DISPOSAL OF EXPOSED FILTER MEDIUM AND COLLECTED DEBRIS The frequency of filter medium exchange will be in accordance with the existing DPS -Customer Maintenance Contract. DPS recommends that the medium be changed at least once per year. During the appropriate service, or if so determined by the service technician during a non-scheduled service, the filter medium will be replaced with new material and the exposed adsorbent placed in a DOT approved container, along with the exposed debris. Once the exposed pouches and debris have been placed in the container, DPS has possession and must dispose of it in accordance with local, state and federal agency requirements. Note: As the generator, the landowner is aChmtely responsible for the proper disposal of the exposed Jlher medium and debris. Because the materials likely contain petroleum hydrocarbons, heavy metals and other harmful pollutants, the materials must be treated as an EPA Class 2 Hazardous Waste and properly disposed of. DPS relieves the landowner of the actual disposal task, and provides certfication of its completion in accordance with appropriate regulations.

As a result, the total volume of runoff from the pervious site exceeds the volume from the impervious site, leading to a greater pollutant mass load to the stormwater treatment system. Therefore, it is critical to assess your site characteristics and to verify that the number of cartridges in the StormFilter system will adequately handle the mass loading from your site. The following calculations include steps for designing your system to adequately treat the runoff resulting from a larger pervious site that yields the same peak flow rate as a smaller impervious site. To determine the number of StormFilter cartridges needed for a pervious site (570% impervious): 1. Determine the peak flow rate from the water quality storm for the pervious site (Qtreat) using the approved hydrologic models established by your local agency. If there are no agency guidelines, we recommend using the Santa Barbara Urban Hydrograph Method. 2. Calculate the number of cartridges required to treat the peak water quality flow rate from the site (Nnow). Assume that Ocart is 15 qpm, unless more information is available. ~ NFlow = Qtreat (449 gpm es / Qcart gp"art) 3. Determine the area of a hypothetical site that is 85% impervious that would produce the same peak water quality flow rate as the highly pervious site. This may require that you initially guess the area and then adjust the area through a few iterations of the hydrologic model. The time of concentration should be adjusted accordingly. 4. Determine the volume of runoff from the pervious site (Vp,,,,ious) using the hydrograph calculated in Step 1. 5. Determine the volume of runoff from the impervious site Wimpervious) using the hydrograph calculated in Step 3. • 6. Calculate the adjusted number of filter cartridges required to treat the water quality flow rate (Nad) when taking into consideration the site watershed characteristics. ~ Nadi = [Qtreat (449 gpmItis / Qoart gpnwcart)] iVpervious / Vimpervious] Note: • Assume Qcart = 15 gpmrcart, which is the maximum flow rate that an individual cartridge can treat. In some areas or situations, cartridges with a flow rate other than 15 gpm may be required, resulting in a different Qcart value. • If the number of cartridges is not a whole number, round the number of cartridges up to the next whole number. 7. Compare the number of cartridges required when considering site watershed characteristics (Step 6) to the minimum number of cartridges required to treat the peak water quality flow rate (Step 2). Use the larger of the two numbers. P�i2 C,4�Rt���- 1,5 gm oa 2 els p .

After our conversation I realized that the 1-18" cartridge CBSF with 2.55' drop was ordered by the contractor and ready to be shipped. I also talked with Jeremy, who originally worked with you on this project and realized that the flows were not provided to us. We are in the process of discussion with the precaster if we can use one of our "orphan" (new unit, which was cancelled) CBSF with 2- 18" cartridges to meet the treatment requirements. We believe that this can be achieved and if verified by the precaster, we will propose to provide the contractor with 2- cart CBSF for the quoted price. I will let you know as soon I will find out.

These guidelines should be used as a part of your site stormwater plan. Overview The CatchBasin StormFilterTm (CBSF) consists of a multi-chamber steel, concrete, or plastic catch basin unit that can contain up to four StormFilter cartridges. The steel CBSF is offered both as a standard and as a deep unit. The CBSF is installed flush with the finished grade and is applicable for both constrained lot and retrofit applications. It can also be fitted with an inlet pipe for roof leaders or similar applications. The CBSF unit treats peak water quality design flows up to 0.13 cfs, coupled with an internal weir overflow capacity of 1.0 cfs for the standard unit, and 1.8 cfs for the deep steel and concrete units. Plastic units have an internal weir overflow capacity of 0.5 cfs. Design Operation The CBSF is installed as the primary receiver of runoff, similar to a standard, grated catch basin. The steel and concrete CBSF units have an H-20 rated, traffic - bearing lid that allows the filter to be installed in parking lots, and for all practical purposes, takes up no land area. Plastic units can be used in landscaped areas and for other non -traffic -bearing applications. The CBSF consists of a sumped inlet chamber and a cartridge chamber(s). Runoff enters the sumped inlet chamber either by sheet flow from a paved surface or from an inlet pipe discharging directly to the unit vault. The inlet chamber is equipped with an internal baffle, which traps debris and floating oil and grease, and an overflow weir. While in the inlet chamber, heavier solids are allowed to settle into the deep sump, while lighter solids and soluble pollutants are directed under the baffle and into the cartridge chamber through a port between the baffle and the overflow weir. Once in the cartridge chamber, polluted water ponds and percolates horizontally through the media in the filter cartridges. Treated water collects in the cartridge's center tube from where it is directed by an under -drain manifold to the outlet pipe on the downstream side of the overflow weir and discharged. When flows into the CBSF exceed the water quality design value, excess water spills over the overflow weir, bypassing the cartridge bay, and discharges to the outlet pipe. Applications The CBSF is particularly useful where small flows are being treated or for sites that are flat and have little available hydraulic head to spare. The unit is ideal for applications in which standard catch basins are to be used. Both water quality and catchment issues can be resolved with the use of the CBSF. Retro -Fit The retrofit market has many possible applications for the CBSF. The CBSF can be installed by replacing an existing catch basin without having to "chase the grade," thus reducing the high cost of re - piping the storm system. 02006 CONTECH Stor ater Solutiom Toll-free: 800.648.48671 of contechsto atff. Catch8asln StonnFllter Operation and Malntar Guidelines CJ • • Maintenance Guidelines Maintenance procedures for typical catch basins can be applied to the CatchBasin StormFilter (CBSF). The filter cartridges contained in the CBSF are easily removed and replaced during maintenance activities according to the following guidelines. 1. Establish a safe working area as per typical catch basin service activity. 2. Remove steel grate and diamond plate cover (weight � 100 lbs. each). 3. Tum cartridge(s) counter -clockwise to disconnect from pipe manifold. 4. Remove 4" center cap from cartridge and replace with lifting cap. 5. Remove cartridge(s) from catch basin by hand or with vector truck boom. 6. Remove accumulated sediment via vector truck (min. clearance 13" x 24"). 7. Remove accumulated sediment from cartridge bay. (min. clearance 9.25" x 11") 8. Rinse interior of both bays and vector remaining water and sediment. 9. Install fresh cartridge(s) threading clockwise to pipe manifold. 10. Replace cover and grate. 11. Return original cartridges to CONTECH Stormwater Solutions for cleaning and media disposal. Media may be removed from the filter cartridges using the vector truck before the cartridges are removed from the catch basin structure. Empty cartridges can be easily removed from the catch basin structure by hand. Empty cartridges should be reassembled and returned to CONTECH Stormwater Solutions, as appropriate. Materials required include a lifting cap, vector truck, and fresh filter cartridges. Contact CONTECH Stormwater Solutions for specifications and availability of the lifting cap. The vactor truck must be equipped with a hose capable of reaching areas of restricted clearance. The owner may refresh spent cartridges. Refreshed cartridges are also available from CONTECH Stormwater Solutions on an exchange basis. Contact the maintenance department of CONTECH Stormwater Solutions at (503) 240-3393 for more information. Maintenance is estimated at 26 minutes of site time. For units with more than one cartridge, add approximately 5 minutes for each additional cartridge.

In BMPs with standing water, which could provide mosquito breeding habitat, certain abatement measures can be taken. 1. Periodic observation of the standing water to determine if the facility is harboring mosquito larvae. 2. Regular catch basin maintenance 3. Use of larvicides containing Bacillus thuringiensis israelensis (BTI). BTI is a bacterium toxic to mosquito and black fly larvae. In some cases, the presence of petroleum hydrocarbons may interrupt the mosquito growth cycle. Using Larvicides in the CatchBasin StorraFliter Larvicides should be used according to manufacturer's recommendations. Two widely available products are Mosquito Dunks and Summit B.t.i. Briquets. For more information, visit http://www.summitchemical.com/mos_ctrVd efault.htm. The larvicide must be in contact with the permanent pool. The larvicide should also be fastened to the CatchBasin StormFilter by string or wire to prevent displacement by high flows. A magnet can be used with a steel catch basin.
