Waste from parks: Waste produced in parks includes green waste that is biodegradable, such as grass, flower cuttings, hedge trimmings. These can originate from activities that include gardening, landscaping, driving, loading and unloading materials_ They also include activities related to the maintenance of fields used for sports and the maintenance of a community sports park. Commercial waste: Commercial waste includes wastes generated by premises that are used wholly or mainly for the purposes of trade or business, or the purposes of sport, recreation, education or entertainment. These include wastes, refuse, chemicals associated with school related activities, as well as activities associated with the operation of a sports complex. All of these wastes are to be handled according to appropriate city, county, state, and federal requirements. Domestic and commercial wastes will be collected and disposed of on a regularly scheduled basis both during and after project construction. � Page 5 � Water Quality Management Plan (WQMP) Roripaugh Rauch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 Materials Storage and Delivery Areas: Designated sites will be allocated for materials storage and delivery. Chemicals for pool operation, lawn maintenance and other required activities will be stored within appropriately designed structures according to city, county, state and federal requirements. Materials will be covered in advance of rain events and delivery areas will be kept clean and free of trash, debris and sediment. Materials and storage delivery areas will be maintained in a manner to reduce or eliminate the pollution of stormwater. Wastes will be placed in appropriately designed containers at protected and covered sites throughout the project site. The types of containers that will be used are listed below. Domestic waste: Domestic wastes will be placed in curbside garbage containers. These containers will not, however, be used for paints, oils, cleaning products, pesticides or household hazardous wastes, which must be delivered to a recycling center or taken at a scheduled time to a specified Household Hazardous Waste Collection site in Temecula (pickup � schedule is available from the Riverside County Waste Management Department). The local City of Temecula CR&R Waste Recycling Services can provide residences with 60 gallon automated containers and 3 yard temporary bins for clean up projects. Waste from parks: Green wastes generated from park related activities will be placed in containers and collected on a regularly scheduled basis. The containers may include 1.5 to 10 cubic yard rear load dumpsters. Commercial waste: Commercial wastes can be placed into large trash dumpsters (such as 10, 20, 30 or 40 cubic yard roll off dumpsters) that will be emptied on a regularly scheduled basis by a service operating locally. � Page s � Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 Table 1.2: Additional Permits/A rovals Re uired for the Pro'ect AGENCY PERMTI' REQUIRED (YES OR NO) State Department of Fish and Game, 1602 Streambed Yes (permit obtained as part of larger Alteration Agreement Roripaugh Ranch project) SAA 6-2001-205 State Water Resources Control Board, Clean Water Yes (permit obtained as part of larger Act (CWA) Section 401 Water Quality Certification Roripaugh Ranch project) File No. O1C-091; WDID No. 9 0OOO1C091 US Army Corps of Engineers, CWA Section 404 Yes (permit obtained as part of larger permit Roripaugh Ranch project) Sectioo 404 Permit No. 97-2010800- RRS US Fish and Wildlife, Endangered Species Act section Yes (obtained as part of larger Roripaugh 7 Biological Opinion Ranch project) NPDES General Permit for Storm Water Discharges Yes associated with Construction Activity (General � Permit) Water Quality Order 99-08-DWQ City of Temecula Grading Permit Yes City of Temecula Building Permit Yes � Page 7 � Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 Vicinity Map and Site Plan: Appendix B of this project-specific WQMP shall include: 1.

The BMPs that will be included within the project are designed to remove sediment and chemical constituents of urban runoff after construction, including potential legacy pesticides and nutrients from historical agricultural activities. Discussion of Pollutant of Concern The runoff from this project is anticipated to discharge into Murrieta Creek. This watercourse is listed on the 2002 303(d) list as impaired for phosphorous, a nutrient. As such, the POC for this site is phosphorous. � � pa9e 21 � Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 IV. Hydrologic Conditions of Concern As required by Section 4.4 of the Riverside County Water Quality Management Plan for Urban Runoff, a 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 facility. The runoff from this project is not discharged directly into a MS4 faciliry. Condition B: The project disturbs less than 1 acre of land. This project disturbs greater than one acre of land. Condition C: The project's runoff flow rate, volume, velocity and duration for the post- development condition do not exceed those of the pre-development � condition for the 2-year, 24-hour and 10-year, 24-hour rainfall events. A HEC-1 analysis of runoff from the site shows that the project's runoff flow rate and volume exceed those of the pre-development condition for the 2 year•, 24-hour and 10 year, 24-hour rainfall events. Therefore, in accof°dance with Section 4.4 of the Riverside County Water Quality Management Plan for Urban Runoff, the Applicant is including an evaluation of potential of the project to cause a significant increase in downstream erosion compared to the pre-development condition andlor cause significant adverse impacts to stream habitat. Santa Gertrudis Creek and Long Valley Wash flow through engineered channels within the Roripaugh Ranch project. Downstream of the project Long Valley Wash confluences with Santa Gertrudis Creek. Santa Gertrudis Creek then continues downstream to its confluence with Murrieta Creek. Downstream of the Roripaugh Ranch Project, Santa Gertrudis Creek can be divided into three reaches. The first reach runs from Butterfield Stage Road to Fiesta Ranch Road. The second reach runs from Fiesta Ranch Road to Joseph Road. The third reach runs from Joseph Road to the conJluence with Murrieta Creek. The first and third reaches will eventually consist of engineered channels. � Page 22 � Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 The second reach of Santa Gertrudis Creek is a natural channel between Fiesta Ranch Road and Joseph Road. This 40 to 80 foot wide reach has an earthen bottom and side slopes. In portions of this natural reach the unconfined creek becomes a series of braided channels and the banks appear unstable. A small portion, but not all, of this natural reach will be improved as part of Roripaugh Ranch development. The remaining portion of this reach to Joseph Road, will remain natural. The attached drainage analysis shows the increase in post p��oject stormwater flows from Roripaugh Ranch into Santa Gertrudis Creek. These post project flows actually diminish with respect to current flows. However, potential exists for these flows to impact the unstable slopes of the natural reach. Such adverse hydrologic impacts would not be fully »2itigated by the implementation of Site Design BMP concepts because the approved tract map does not provide for sufficient on-site infiltration to reduce peak flows sufficiently and because the reconfigured topography � within the project site will not allow runoff to mimic existing conditions. Therefore, in accordance with Section 4.4 of the Riverside Counry Water Quality Management Plan for Urban Runoff (September, 2004), the project applicant will adopt `Methodology A' to address the potential impacts to Santa Gertrudis Creek. `Methodology A' involves designing a detention basin capable of all of the following.• 1. Releasing the post-development 2 year and 10 year, 24-hour volume at flow rates less than or equal to the pre-development 2 year and 10- year, 24-hour peak flow rates, respectively. 2. Passing the 100 year storm event without damage to the facility. 3. Controlling outlet velocities such that downstream erosion and habitat loss is minimized. A summary of hydrologic flow rates from the pre- and post-development conditions is included in Appendix C, Table C-1: "Summary of Flow Rates Calculated from HEC-1 Hydraulic Model.

Magimize canopy interception and water conservation by preserving e�isting native trees and shrubs, and planting additional native or drought tolerant trees and large shrubs. Description: Because the site will largely be graded and because the existing vegetation cover is sparse, only a small quantity of existing trees will be preserved However the development includes planting new trees and shrubs that are native and/or drought tolerant, thereby increasing canopy interception (I.C.b. of this section includes a list of candidate species that can be planted). Table 5.2 identifies the dimensions of street buffers and landscaped median widths that will be incorporated to maximize canopy interception and water conservation. The overall project will also include 202 acres of natural open space. I.A.d. Use natural drainage systems. Description: Tlze proposed grading of the project wiU generally maintain the existing historic drainage patterns onsite. The project will collect and convey runoff through developed areas via a combination of � curbs, gutters and storm drains that eventually connect to the natural drainage channels of Long Valley Wash and Santa Gertrudis Creek. I.A.e. Where soil conditions are suitable, use perforated pipe or gravel filtration pits for low flow infiltration. Description: Perforated pipes will not be incorporated into the project design to provide low flow infiltration for e.zcess stormwater runoff. Alternatively, rivo dual-use vegetated swale/infiltration systems within the project site will provide low flow infzltration. Runoff from tentative tracts 30766, 32354, 32355, 32356, and a portion of tract 29368 within the western portion of this project will enter Swale 1.

Description: Permeable ureas will be ma.�imized by incorporating vegetated areas within the project site. As described in the Roripaugh � Ranch Specific Plan, the landscaping design shall include trees, shrubs and ground cover. Vegetation shall include native and /or drought-tolerant species (see I.C.b. of this section for a list of candidate species) to increase overall site permeability. Portions ofLong Valley Channel will be widened with a soft bottom and lined with armorflex along the b¢nks. The armorflex will be hydroseeded, as requested by the RWQCB. I.B.b. Construct walkways, trails, patios, overflow parking lots, alleys, driveways, low- traffic streets and other low-traffic areas with open-jointed paving materials or permeable surfaces, such as porous concrete, porous asphalt, unit pavers, and granular materials. Description: The project design will not incorporate open-jointed paving material and permeable surfaces such as porous concrete or asphal� This project will alternatively include vegetated buffers adjacent to streets and two vegetated swales. Infiltration will occur within these swales (Appendix Fprovides information on the quantity of infiltration and the sizing of vegetated swales). I.B.c. Construct streets, sidewalks and parking lot aisles to the minimum widths necessary, provide that public safety and a walkable environment for pedestrians are not compromised. Description: The widths of streets, sidewalks and parking lots have been limited � Page 35 � Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Teotative Tract No. 29353-2 & 29353-3 October, 2006 to minimum widths specified by the City of Temecula to reduce areas of impermeable surjaces. Table 5.2, Figure 5.1, and Figure B.2 highlight landscaped buffer and median widths. I.B.d. Reduce widths of street where off-street parking is available. Description: On streets where off-street parking is available, street widths have been designed to the minimum widths required by the City of Temecula to reduce areas of impermeable surface. I.B.e. Minimize the use of impervious surfaces, such as decorative concrete, in the ' landscape design. Description: No decorative surfaces have yet been designed or planned for incorporation into the projecL The project desian instead includes pervious areas, such as landscaping along road medians and sidewalks (see Table 5.2, Figure S.l, and Figure B.2).

Other comparable and equally effective site design concepts as approved by the Co-Permittee. � Description: Tlxe two vegetated swales will allow particles and pollutants to settle out and infiltration to occur (see Appendix F for discussion of infiltration). I.C. Conserve Natural Areas I.C.a. Conserve natural areas (see WQMP Section 4.5.1) Descsipt�on: The proposed grading of the project will also generally maintain the existing historic drainage patterns onsite. Because the site will largely be graded and because the existing vegetation cover is sparse, only a small quantity of existing trees may be preserved However the development includes planting new trees and shrubs that are native and/or drought tolerant, thereby increasing canopy interception (I.C.b. of this section includes a list of candidate species that can be planted).

Magimize canopy interception and water conservation by preserving existing native trees and shrubs, and planting additional native or drought tolerant trees and large shrubs. � Description: Landscape s[ope protection will be incorporated on all excavated slopes. The project development includes planting new trees and Page 36 � Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 shrubs throughout the sitet, thereby increasing canopy interception. These include drought tolerant and/or native trees/shrubs. Candidate species include: Trees and tree-like shrubs: Coast live oak (Quercus agrifolia) Scrub oak (Quercus dumosa) Laurel sumac (Malosma Laurina) Bush mallow (Malacothamnus fasciculatus) Flannelbush (Fremontodendron calijornicum) Coyote bush (Baccharis pilularis) Blue elderberry (Sambucus mexicanus) Toyon (Heterome[es arbutifolia) Lemonade berry (Rhus integrifolia) Huckbrush (Ceanothus cuneatus) Squaw bush (Rhus trilobata) SmaUer shrubs for IandscapinQ: Brittlebush (Encelia farinosa) Matilija poppy (Romneya coulteri) Black sage (Salvia mellifera) � White sage (Salvia apiana) I.C.c. Use natural draioage systems. Description: The proposed grading of the project will generally maintain the e.zisting historic drainage patterns onsite, including thal of Long Valley Channel (shown on Exhibit B.I: WQMP Site Plan). The project will collect and convey runoff through developed areas via a combination of curbs, guners and storm drains that eventually channel water to the natural drainage channels ofLong Valley Channel and Santa Gertrudis Creek. I.C.d. Other comparable and equally effective site design concepts as approved by the Co-permittee Description: The primary design concepts that will serve this project include vegetated buffers, inclusion of open space and vegetated swales. Other opportunities for increasing infiltration will be considered if they arise during more detailed project design. II. Site Design Concept 2 II.A. Minimize Directly Connected Impervious Areas (DCIAs) II.A.a. Residential and commercial sites must be designed to contain and infiltrate roof runoff, or direct roof runoff to vegetation swales or buffer areas, where feasible. page 37 � Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 Description: Roof runoff from residentia[ and commercial sites first flows into areas adjacent to buildings before it drains to roads. In some cases these areas include lawns that allow infiltration to occur. Runofffrom tentative tracts 29367, 30766, 32354, 32355, 32356, and from portions oJ tentative tracts Z9366 and 29368 is directed into Swale 1 or Swale 2. II.A.b. Where landscaping is proposed, drain impervious sidewalks, walkways, trails, and patios into adjacent landscaping. Description: Landscaping is provided between sidewalks and street curbs to the e�tent allowed by the Riverside County and City of Temecula Road Improvement Standards (see Table 5.2, Figure 5.1, and Figure B.2). This aUows runoff from impervious sidewalks and driveways to flow into vegetated areas and lawns adjacent to these areas, although the runoff is not channeled directly into them. Instead, storm water runoff is directed via a storm drain system to orie of two vegetated swales. Both swales allow � infiltration to occur (see Appendix F for data on infiltration). II.A.c. Increase the use of vegetated drainage swales in lieu of underground piping or imperviously lines swales. Description: The project incorporates two vegetated swales. Runoff from tentative tracts 30766, 32354, 32355, 32356, and a portion of tract 29368 within the western portion of this project witl enter Swale 1. Runoff from tentative tract 29367 and portions of'tentative tracts 29366 and 29368 within the eastern portion of this project will enter Swale 2. II.A.d. Rural swale system: street sheet flows to vegetated swale or gravel shoulder, curbs at street corners, culverts under driveways and street crossing. Description: Rural swa[e systems are not a part of this projec� The project will alternatively incorporate vegetated swales. These swales serve tentative tracts 30766, 32354, 32355, 32356, 29367, 29368, and a portion of tentative tract 29366. II.A.e. Urban curb/swale system: street slope to curb; periodic swale inlets � drain to vegetated swale/biofilter. Page 38 � Water Quality Maoagement Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 Description: Urban curb/swale syste»rs are not a part of this projecL The project will alternatively incorporate two vegetated swales. II.A.f. Dual drainage system. First flush captured in street catch basins and disc6arged to adjacent vegetated swaie or gravel shoulder, hig6 flows connect directly to MS4s. Description: High flows within the project do not connect directly to MS4s. Alternatively, flows emanating from tentative tracts 29367, 29368, 30766, 32359, 32355, 32356, 29368, and from portions of tentative tract 29366 are captured within a storm drain system and channeled to one of rivo vegetated swales. Flows from other tracts are directed to vertical filtration units that treat pollufants of concern. II.A.g. Design driveways with shared access, flared (single lane at street) or wheel strips (paving only under tires); or draio landscaping prior to discharging to the MS4. Description: Driveways with shared access or wheel strips are not � included in the project design. Alternatively, landscaping is provided between sidewalks and street curbs to the extent allowed by Riverside County and the City of Temecula Road Improvement Standards (see Table 5.2, Figure 5.1, and Figure B.2). This allows runoff from impervious sidewalks and driveways to flow (although it is not specifically channeled) into lawns adjacent to sidewatks. II.A.h. Uncovered temporary or guest parking on private residential lots may be paved with a permeable surface, or designed to drain into landscaping prior to discharging to the MS4. Description: Permeable parking surfaces are not included as part of this projecz Alternatively, the project will incorporate landscaping in buffered areas adjacent to sidewa[ks, as well as two vegetated swales. II.A.i. Where landscaping is proposed in parking areas, incorporate landscape areas into the drainage design. Description: Landscaping in parking areas is not hydraulically incorporated directly into the drainage design. The project wil[ alternatively incorporate landscaping in buffered areas adjacent to sidewalks and street curbs to provide � partial infiltration. Page 39 � Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Teotative Tract No. 29353-2 & 29353-3 October, 2006 II.A.j. Overflow parking (parking stalls provided in excess of the Co- Permittee's minimum parking requirements) may be constructed with permeable paving. Description: Overflow parking with permeable paving will not be incorporated into the project design. Alternatively, landscaping is provided between sidewalks and street curbs adjacent to parking areas to the extent allowed by the Riverside County and City of Temecula Road Improvement Standards (see Table 5.2, Figure S.I, or Figure B.2). This allows runofffrom impervious sidewalks and driveways to flow (although it is not specifzcally channeled) into lawns adjacent to the sidewalks. II.A.k. Other comparable and equally effective site design concepts as approved by the Co-permittee. Description: The project design allows for infiltration into soils wiihin two vegetated swales (see Appendix F for information on quantity of infiltration). Other opportunities jor conserving natural areas and � for increasing landscaping will be considered if they arise during furthe� detailed project design. � Page 40 � Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 V.2 SOURCE CONTROL BMPS Source Control BMPs are listed in Table 52 below.

The first primary BMP is a vegetated swale (two will be located on site) and the second primary BMP is a proprietary vertical filtration unit (the number and locations of these individual units are identified in Exhibit B.l : WQMP Site Plan). Table 5.4 identifies the number of principal Treatment Control BMPs that will treat each project tract. Table 5.5, the Treatment Burden and Treatment Capacity Summary Chart, identifies more specific information regarding types of treatment control BMPs that will be used to address each tract within the project. When runoff from one tract is treated by more than one BMP, the table identifies the separate acreages treated by each BMP, as. well as the associated BMP volumes and flow rates. Figure B.2 and Figure C.2 provide a graphical illustration for Table 5.5. Figure B.2 (WQMP Site Plan) identifies the separate project tracts and shows the locations of both vegetated swales and all filters that will be used as BMPs. Figure C.2 (Proposed � Hydrology Map) illustrates the sub drainage basins and their acreages. These tables illustrate how stormwater from each project tract will be treated, independent of the Master Development. Phasing of Treatment Control BMPs Proposed treatment control BMPs will be constructed / installed and will be operational before portions of the project they serve are occupied. Both Swale 1 and Swale 2(and accompanying basins in which they are located) and each filter BMP will be constructed and capable of treating their requisite QB� before residents and businesses move into project homes and commercial facilities within the project site. Construction schedules that address this phasing requirement will be followed throughout project inception. � ; � � s �� r n- i � � � w �F �` �� +� � � t � � � , �- , � �, > � � 3 4 . , � �.�, t ,s� � x �� , ,� � �P � � �,r.�.4� . � � � �� d . � � � ��a9e � _. ., .._ . ..,, e � �.�.,. ,�� _ . . . . _ �� Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 Table 5.4: Princi al Treatment Control BMPs Tentative Tract Number of StormFilter0 Total Number of and density of land System units Vegetated Swales servin� use or equivalent located within specific tentative tract tracts that serve tracts (units) (units) 29366 (NIDR) 1 1 29367 (LDR) 0 1 29368 (LMDR) 0 2 30766 (LDR and OS) 0 1 30767 (LDR) 1 0 30768 (NIDR) 2 0 32354 (Comm) 0 1 32355 (NIDR) 0 1 32356 (MDR) 0 1 32357 (MDR) 0 PA 30 1 0 32358 (NIDR) 1 0 � PA 27 (Sports Park) 1 0 PA 28 (School) 2 0 PA 29 (School) 0 TOTAL 9 NA � ,. „ _ . _ , _ >, - _ ` . 9 . , : .

Because both vegetated swales are underlain with gravel packs that will serve to facilitate infiltration to the underlying soil, these swales also serve as infiltration BMPs. These swale \ infiltration systems were selected because of their effectiveness in reducing specific pollutants identified as potentially able to impair receiving waters to which this project discharges urban runoff. Each swale/infiltration BMP is located within a detention basin (note that these detention basins are used for flood control purposes and are not BMPs designed for water quality purposes�. As such, there is no need for them to include a controlled outlet channel). Vegetated Swale Number 1 is located within flood control Basin 1, located at the north- east corner of the intersection of North Loop Road and Butterfield Stage Road. Stormwater enters the southern end of the swale through a storm drain system. During low flows this water moves northward across the vegetated swale (forming the invert, or flow line, of flood control Basin 1) before discharging and flowing south and west through a storm drain system to enter Long Valley Channel. From this point the flow exits the project site (the swale does not require a water quality outlet). � Vegetated Swale Number 2 is located within flood control Basin 2, located at tl�e south- east corner of the intersection of the Loop Branch Road and Long Valley Channel. Stormwater enters the western end of the swale within Basin 2 through a storm drain system that connects to a`splitter box' (a low flow / high flow separator). This flow then moves eastward across the vegetated swale (forming the invert, or flow line, of Basin 2) before it enters a wet well. The treated water is then pumped northward to Long Valley Channel. A gravel pack underlying swale facilitates infiltration (data provided in Appendix F). Supporting engineering calculations for QB� are included in Appendix C. Treatment Control BMP design details are included in Appendix F. Inspection and maintenance of both vegetated swales / infiltration systems will take place after storm events, as well as on a routinely scheduled basis of every two weeks. As suggested by the Riverside County WQMP, maintenance activities will focus on vegetation management and vector control. Depending on conditions at the swales, debris accumulations will periodically be removed. � The detention basins have been designed according to calculated differences in flows between the developed and ❑ndeveloped site conditions for the 2-year, 24-hour, the ]0-year, 24-hour, and the 100-year, 3-hour storm events. � HEC-1 modeling calculations for these storm conditions are provided in Appendix C. � Page 50 Water Quality Management Plan (WQMP) Roripaugh Ranch Project, Tentative Tract No. 29353-2 & 29353-3 October, 2006 Vegetated Swales / Infiltration BMPs — Technical Information: Both vegetated swales are designed according to criteria established by the Riverside County Flood Control District (RCFCD). Design calculations for both swales are included in Appendix F. Both vegetated swales will be underlain by a 1' deep subsurface gravel bed wrapped in a filter cloth that will faciiifate the capture and treatment of first flush pollutants. The nutrient phosphorous is a CWA Section 303(d) pollutant of concern for the project. Levels of phosphorous that will be generated by project development are not expected to exceed levels generated by similar types and sizes of mixed-use development projects within Riverside County. Because of the inclusion of a sub-grade gravel pack, the vegetated swale / infiltration BMPs within the project are designed to act as infiltration BMPs and to remove phosphorous generated by the project. The vegetated swales will also treat bacteria and viruses generated by the project. During a meeting in March, 20Q6, RCFCD announced that they are planning to make landscape BMPs (including vegetated swales) as their preferred future choice of primary treatment for storniwater flows from residential tracts. RCFCD also announced that they will consider vegetated swales designed according to their specifications to treat bacteria and � viruses to a medium to high level (this will be reflected in their forthcoming revised design manual). Infiltration: The vegetated swales that comprise the bases of both Basin 1 and Basin 2 allow inf ltration to occur. Because both swale bottoms consist of graded land containing Type B soil (according to the Riverside County Flood Control Manual of Hydrology). Appendix F includes data on the quantity of infiltration into the vegetated swales during low flows. � Z March 27, 2006.

Unlike catch basin inserts ar hydrodynamic separators, these filtration system units contain a chamber that detains flow for long enough to allows effective treatment of bacteria and pathogens. These units include rechargeable media-filled filter cartridges (using perlite/zeolite media). This type of filtration unit was approved for removing pollutants of concern (including bacteria and viruses) to an acceptable level by the City of Temecula in another recent development project.

Operation and Maintenance Responsibility For Source and Treatment Control BMPs Inspection and maintenance of Source Control BMPs, Site Design BMPs and Treatment Control BMPs will primarily be the responsibility of the developer initially, and will later become the responsibility of the site Home Owners Association (HOA) and the site Property Owners Association (POA) when these entities are formed. The time of the transfer of responsibility will be mutually decided on by the developer and home builders during project implementation. The HOA and POA to be formed will operate from bases located within the project site. Flood control channels will be maintained by Riverside County Flood Control and Water Conservation District under contract with the HOA / POA. Once the HOA / POA are formed, routine inspections of each BMP, analysis of its functional adequacy and maintenance of each BMP will be the responsibility of the HOA / POA and in some specific cases the City of Temecula or Riverside County, when on contract with either of these entities. Inspections of all BMPs will be performed on a regularly scheduled basis, and in many cases will also take place before and after each � storm or precipitation event (inspections before precipitation events take place when the • regional meteorological forecast includes a 40% or greater chance of precipitation at the project site). Additional inspections of BMPs will take place when required by any unusual conditions or events that warrant inspection. The BMP Inspection / Maintenance Responsibility and Frequency Matrix provided on the following pages identifies what primary organization is responsible for each BMP inspection / maintenance activity. The matrix recommends a frequency of inspection and maintenance activities. Although specific startup dates for each specific BMP have not yet been determined because of possible modifications to the project construction schedule, each BMP shall become operational when construction is completed on the tracts they serve. Maintenance activities will begin simultaneously.

Roripauqh Ranch- Stormwater Treatment Svstem Maintenance Cost Estimate Redland, CA The following maintenance estimate is for the stormwater treatment systems recommended by CONTECH Stormwater Solutions for the Roripaugh Ranch project. Typically, we recommend annual maintenance services for the stormwater treatment systems. However, depending on rainfall conditions and mass loading volumes, the treatment systems may only need maintenance once every two to three years in California. Stormwater pollutant source control practices can also greatly affect the pollutant loading on the system and maintenance frequency. StormFilter CONTECH Stormwater Solutions offers complete maintenance of the StormFilter system which is defined as removing and disposing of the accumulated trash and debris, sediments and other target pollutants from the StormFilter and replacing spent media cartridges for new cartridges. If contracted with CONTECH Stormwater Solutions the estimated maintenance cost for these systems is $190, per cartridQe, per � cYc�e. CONTECH Stormwater Solutions also offers a cartridge exchange program. Recharged cartridges may be purchased from Stormwater Management for installation by the Owner. This method of maintenance could reduce cost if the Owner has a crew available to provide the labor and equipment. The cartridge exchange price is 115 er cartridqe, per cycle, shipping not included. � ,. �� - �� '� ��s , .r ... ... e „,G±.-�: � r ^ �FN, � � r ' wro`a �.i �� ,. � �: Rx;. �f p w ,.w °�n an _ ..,. •��' 4 „� ..� ,„�..._:_.,-:- ....�....,» . . . - .. .,,,d y s,�� ..:.: - . ��.... . °: ..�,. . . r ... . . . .... .,: .-� .�., .,. . -�.�___.' � � � .. - ^ ..e�'�` � ....._ � .. .. ... � " � �+c.� � _ E« ,. i .. 6' m �� '��`�°;' �� contechstormwater_com � ,a � . . x. _ � , m.,.. � '�'"'` - ��'12021=6,NE`Airport �ra;.

Performance of the Stormwater Management StormFilter for Removal of Bacteria Microbial contaminants, generally referred to as bacteria, are frequently identified as a pollutant of concern and are common in stormwater runoff from both developed and undeveloped areas. Typicaily, fecal coliform is used as an indicator that enteric organisms may be present in the stormwater runoff and is used to set water quality standards. Human waste is a common source of fecal coliform; other sources include pets and urban wildlife, native wildlife in rural areas, and to a surprising extent, birds (Burton and Pitt, 2002; Crabill et ai., 1999; Grant et al., 2001; Apicella, undated; WPT, 1999). The concentration of indicator microbial contaminants in urban stormwater is routinely measured in the thousands to tens of thousands of organisms per 100 mL range (Burton and Pitt, 2002). Typical federal coliform standards for different water uses range from less than 14 MPN (most probable number) per 100 mL for sheilfish beds to less than 200 MPN per 100 mL for water contact recreation. Studies have found that mean fecal coliform concentrations � in stormwater runoff may well exceed 20,000 colonies per 100 mL (WPT, 1999). Given the concentrations of bacteria commoniy found in stormwater, this could represent a required removal efficiency of 99.9% (WPT, 1999; NRDC, 2001). Fecal coliform levels may vary greatly depending on occurrences of dry weather flows, seasonal effects, and impervious cover. Effective reduction to meet federal regulations is best achieved through a technology such as ultraviolet disinfection, ozone disinfection or chlorination. Filtration of Stormwater Available research literature indicates that media filtration of stormwater can achieve a significant and reasonable level of bacteria reduction. Compared to other treatment technologies currentiy available, a media filter may be considered treatment to the "maximum extent practicai". Since media filters, including sand filters, have no astringent properties, the removal of fecal coliform is typically associated with the removal of total suspended solids (TSS). An article from Watershed Protection Techniques (1999) establishes a link between bacteria and sediment. This article suggests 50% of fecal coliform bacteria are attached or adsorbed to larger suspended particles in stormwater. These larger particies can then be settled or fiitered out. In general, the article concludes that filters are very effective for removing bacteria associated with TSS. The Stormwater Management StormFilter0 is a passive, siphon-actuated, flow-through stormwater filtration system consisting of a structure that houses rechargeable, media- filled fiiter cartridges. The StormFilter has been demonstrated to be an effective BMP for � Stormwater Management, Inc. 02004 StormFilter Performance for Bacteria 1 of 3 AG-04.13, 12/15/04 � the removal of TSS (WADOE, 2004). Hence, according to the research presented by Schueler, the StormFilter will provide a reasonabie removal of bacteria. It is important to note that sampiing to determine the performance of stormwater BMPs with regards to bacteria removal is quite chailenging. To ensure minimal die-off of the organisms between sampling and analysis, sample hold times are very short (approximately eight hours). In addition, samples must typicaliy be manual grab samples with sterile equipment. Finally, there is such high variability in the level of organisms in the influent and effluent flows that many samples are required to adequately characterize facility performance. This combination of variability, sampling difficulties and required number of samples results in few field data or definitive reports on bacteria removal for any stormwater BMP. Study Results A laboratory study evaluating both bench scale and column tests of the CSFO leaf inedia demonstrated reasonable removals of both fecal coliform and E. coli. For the bench scale test, the media demonstrated removai efficiencies for fecal coliform on the order or 50 — 60% and for E. coli on the order of 65 — 75%. Column tests showed average removal for fecal coliform of 47% and E. coli of 30% (Roy, 1995). In a California field study, the StormFilter using perlite/zeolite media achieved an � average bacteria reduction of 47% even with a TSS removal of 50%, which is on the low end of the StormFilter performance scale (Caltrans, 2004). Bacteria reduction in future applications may be even greater if source controls such as street sweeping or removal of leaves and other organic matter upstream of the unit are provided. In addition, the StormFilter media-filled cartridges can be operated at lower cartridge flow rates to maximize contact time with the media and improve removal efficiencies. Finally, bacteria removals can be improved by ensuring complete drain down of stormwater devices between storms. This prevents mosquito breeding and eliminates putrefaction of collected pollutants, thereby limiting the availability of hosts for bacteria. Conclusion In conclusion, given the few data points and limited available literature, the StormFilter provides a level of bacteria removal consistent with other stormwater filtration systems.

Nine different sites with 110 paired influent and effluent samples were evaluated. For the sand filter, 52 paired samples were retrieved from the International Stormwater BMP Database (BMP database) for five sites. For the StormFilter, 58 paired samples were analyzed from four peer reviewed and/or independent studies. Regression of Event Mean Concentration (EMC) results indicates that there was no statistical difference between the StormFilter and sand filter for the removal of total phosphorus. Introduction Total phosphorus (TP), expressed in milligrams/liter is the sum of particulate organic phosphorus, particulate inorganic phosphate, dissolved inorganic phosphorus (ortho- phosphate), and dissolved organic phosphorus. Organic phosphates are a part of plants and animals, their wastes or decomposing remains. Inorganic phosphate originates from decomposing mineral materials and man-made fertilizer products. TP concentrations in stormwater are variable but range from 0.01 to 7.3 mg/L (Minton, 2002)_ Removal of phosphorus can be accomplished by three mechanisms. The first is removal of organic and inorganic phosphorus associated with solids. The second is removal by biological uptake by plants or bacteria. The third is through chemical precipitation such as the reaction of ortho-phosphate with iron to form iron phosphate in aerobic conditions. Both the StormFilter and sand filters primarily remove TP by the removal of solids and can be amended with alternative media like iron to target ortho-phosphate. Approach Sand filter data were retrieved from the International Stormwater BMP Database (www. bmpdatabase.orq) on September 30, 2005. A total of six sand filter investigations that included TP - ali roadway sites - were available from the BMP Database. Only five sites were utilized in this comparison. One sand filter site (I-5/SR-78 P&R — Vista, CA) contained a large variance in data and demonstrated poor performance (-167% aggregate load removal) that was not consistent with the other investigations, and thus was omitted from the analysis. The only criterion for selection was paired influent and effluent samples with the assumption that the BMP database has screened and assured data integrity. The data set represents storm events that were sampled from April 1999 to May 2001. Data used for the StormFilter were collected from four sites that have been either independently tested and/or peer-reviewed. The criteria used for StormFilter data selection was that a final, completed evaluation report was issued as of October 1, 2005; all information has been peer- reviewed; and each investigation evaluated a stand-alone, flow-based StormFilter system using ..�.. .. �.�..,�._,�k.��ti r,,.�,...,,,,.�.�.�.�..�.��.. �._ =._,u_ „�_,,�.,_�.».._.,�,.�,.. u .a.�,G.. �._., -h_, _..,,�� .�� .�� .. ....< ,M.. ,�.,�x.., r 1� of 6� 10/21lOS SID www.stormwater com �02005 Stormwater360 RS-O5-0Sa ZPG (Perlite/Zeolite/Granular Activated Carbon) or Perlite/Zeolite (PZ) media.

Linear regression statistics similar to those suggested by Martin (1988) and URS et al. (1999) were used to estimate the mean TP removal efficiency. instead of using calculated load values as suggested by Martin (1988}, regressions were performed on EMC values alone so as to avoid any error associated with the storm volume data. REMC is a quantitative data analysis method that uses parametric statistics. REMC provides 95% confidence intervals and is more robust than using qualitative data analysis rnethods such as the Line of Comparative Performance, Discrete Removal Efficiencies, or Aggregate Load methods that can be subject to interpretation or require non-parametric statistical tools, such as a sign test. REMC analysis estimates the mean removal efficiency over a range of influent concentrations, and thus yields a continuous series of normal distributions. Resulting standard deviations can thus be used to statistically compare performance. 1.2 a.r�ovA ,�.,� Source of V�riat.i.on df S� MS F ^ E�:plained 1 0.1792 0.17�2 17.59" ' ,_j Une::pla.inad 50 0.509° 0.01019 � Tot�l 51 0_5824 � 1.0 � SIGNIFICANCE OF COEFFICIENTS � O 9 co=rr. srd. error c (, �0=0.0605� 0.02615 3.099" c �=U.1,26E u.07787 9.159" ' G W �.$ '= 0.01 : Y< 0.05 . � � ,..

Although the sand filter demonstrated a higher mean (+3%) than the StormFilter, the StormFilter exhibited more precise range of performance (standard deviation (SD) = 10) than the sand filter (SD = 15). Therefore, these two media filters can be said to have equivalent performance for the removal of total phosphorus. References 2� Nature Environmental Science + Consulting. (2004).

As shown in Figure 1, phosphorus cycles through the environment in forms organic, inorganic and soluble forms.

Inorganic and Organic Cycle (RiverWatch, 2001) Total phosphorus (TP), expressed in milligrams/liter is the sum of inorganic phosphate, organic phosphate, and soluble phosphorus (Ortho-P). Organic phosphates are a part of plants and animals, their wastes or decomposing remains. Inorganic phosphorus originates from decomposing natural materials and man-made products. Non-point source runoff (stormwater) increases phosphorus concentrations in lakes and streams by transporting sediment and organic matter (bud shatter, leaves, lawn clippings, etc.) from impervious surfaces. Additional phosphorus sources in stormwater are misapplied fertilizers, some detergents, and animal waste from birds and domestic pets. Phosphorus in urban runoff is typically measured as TP and sometimes Ortho-P is measured as well. The non-soluble portion of the TP is commonly associated with the total suspended solids (TSS). Of this form, the phosphorus can be in an organic or inorganic form. TP concentrations in stormwater are variable but range from 0.01 to 7.3 mg/L (Minton, 2002). Concentrations of Ortho-P in urban runoff are frequently in concentrations ranging from 0.05 to 0.2 mg/L (Wigginton, Stormwater Management, Inc. 02004 StormFilter Performance, Phosphorus 1 of 4 1999). USEPA guidelines indicate that Ortho-P concentrations in stream in excess of 0.10 mg/L can trigger algae blooms in fresh water lakes. Removal of phosphorus can be accomplished by three mechanisms. The first is removal of organic and inorganic P associated with solids. The second is removal by biological uptake by plants or bacteria. The third is through chemical precipitation such as the reaction of Ortho-P with iron to form iron phosphate in aerobic conditions. Depending on the type of treatment system, organic phosphorus can transform to Ortho-P and be released later. For example, leaves trapped in a sump can decompose or fall senescence of wetland plant can release Ortho-P. Results Performance data for removal of total phosphorus were summarized from ongoing field evaluations. These field evaluations are a combination of first and third party investigations. Data were collected from 9 sites located in different geographic locations (primarily from the West Coast (WA, OR, CA) and a single Midwest site) and configured with different media types at different flow rates. Available reports are listed in the reference section. This performance summary focuses on Total Phosphorus removal only. The following information presented in Figure 3 contains data collected since 2001, mostly during the late spring, summer, and fall for total phosphorus removal by the Stormwater Management StormFilter. Fifty-five data points are presented in Figure 3. The mean removal efficiency using linear regression was 62% with 95% confidence limits of 53% and 78% (lower and upper limits, respectively). Sixteen data points that were included in the analysis did not have a positive removal. Overall these systems demonstrated statistically significant removal (P<0.001; 99% probability of net removal) of Total Phosphorus. Stormwater Management, Inc.

This document has been prepared in accordance with requirements stipulated by the federal National Pollutant Discharge Elimination System (NPDES), the State Water Resources Control Board (SWRCB), and the City of Temecula. The Roripaugh Ranch Project is located on an 804-acre site of land that is currently undeveloped (although grading is now taking place on portions of the project area). When completed the project will include residential, commercial, institutional properties and land designated as open space. Specifically the project will include several residential gated communities, commercial retail units two schools, sports and recreation parks, and a large tract dedicated as open space. After the project is completed, stormwater that discharges from the site will flow downstream via Santa Gertrudis Creek and the Long Valley Channel. The water will flow through a series of water bodies toward the ultimate destination of the Pacific Ocean. Unless treated, this urban runoff is expected to contain a wide spectrum of pollutant categories, including sediment, nutrients, organic compounds, trash and debris, oxygen demanding substances, bacteria and viruses, oil, grease, and pesticides. Phosphorous is the primary pollutant of concern for the project because a downstream water body is impaired by this nutrient, according to the Clean Water Act Section 303(d) list of impaired water segments, Best Management Practices (BMPs) will be implemented at the project site to mitigate the impact of stormwater pollutants to downstream receiving waters. These include Site Design, Source Control, and Treatment Control BMPs. Site Design BMPs will include maintaining the natural drainage systems of Santa Gertrudis Creek and Long Valley Channel on site, the inclusion of 202 acres of open space as well as public parks, and the provision of native and drought resistant trees and landscaped areas between sidewalks and roads. Two types of Treatment Control BMPs will be used to treat pollutants contained in urban runoff. These will be two vegetated swale / infiltration BMPs and eight proprietary manufactured filter units known as Storm Filters. All stormwater flow emanating from the project site will be treated by one of these two types of BMPs before being discharged offsite. Together these BMPs will treat a combined flow rate (QBMp) of 46.7 cfs. Homeowners Associations (HOAs) and at least one Property Owners Association (POA) will be formed to take over inspection, operation and maintenance responsibilities from the developer after residential and cormnercial properties have been constructed. The HOA and POA will abide by water quality CC&Rs that will be finalized after project construction commences. ~�~ California Regional Water Quality Cont�ol �oard � San Diego Region m Over 50 Years Serving San Diego, Orange, and Riverside Comities prnold SChwarzeneggei Linda Adams Secrelary Recipient of the 2004 Environmental Award for Oirtstanding Achievement from USEPA Governor 9174 Sky Park Court, Suite 100, San Diego, California 92123-4353 (858) 467-2952 • Fax (858) 571-6972 � �� http:// www.waterboards.ca.gov/sandiego i�OV 1 � 2006 CITY OF TEME:.ULA CERTIFIED MAIL — RETURN RECEIPT PUBLIC WORKS DEPARTMENT 7004 0750 0001 2969 2691 November 2, 2006 In reply refer to: WPN:10-3020657.02,18-2001091.02:schwk Mr. Peter Olah Ashby USA, LLC 39353 Winchester Road #107-393 - Murrieta, CA 92563 Subject Site: Roripaugh Ranch Residential Development Project RE: NOTICE OF VIOLATION NO.

California Environmental Protection Agency �a Recycled Paper Mr. Peter Olah - 2- November 2, 2006 � Ashby USA, LLC Roripaugh Ranch Residential Development Project Summary of Violations: I.FAILURE TO CONSTRUCT AS REQUIRED BY 401 CERTIFICATION 01 C-091 ➢ Pursuant to 401 Certification 01 C-091 Condition 8: • The existing low flow wash will remain in its natural condition ... Observation: Your site was documented as having disturbed Long Valley Wash from its natural conditions. II.FAILURE TO SUBMIT A CONSERVATION EASEMENT OR DEED RESTRICTION . THAT PROHIBITS THE REMOVAL OF VEGETATION ➢ Pursuant to 401 Certification 01 C-091 Condition 10: • Ashby USA, LLC shall submit, within 90 days of the issuance of this certification, a draft conservation easement or deed restriction that prohibits the removal of native vegetation including, but not limited to, mowing, pruning, and spraying, in Santa Gertrudis Creek and Long Valley Wash on the project site. • Ashby USA, LLC shall submit proof of a completed conservation easement or deed restriction within one year of the issuance of this certification. • Ashby USA, LLC shall also provide written verification that Riverside County Flood Control and Water Conservation District (RCFCWCD) agree to the prohibition. Observations: No draft or final easement or deed restriction has been developed. RCFCWCD has not agreed to the prohibition. III.FAILURE TO COMPLETE MITIGATION ➢ Pursuant to Condition 1 of Minor Modification 2 to 401 Certification 01C-091: • A revised mitigation plan shall be submitted to this office for approval within 60 days of the date of the modification letter, October 20, 2005. Observation: A mitigation plan was not submitted by December 20, 2005, as required and has not been submitted to date. ➢ Pursuant to Condition 2 of Minor Modification 2 to 401 Certification 01C-091: • Mitigation shall be constructed within 1 year that impacts occur, or additional mitigation acreage may be required. Observation: The impacts occurred prior to the issuance of Minor Modification 2 on October 20, 2005, so the date of impacts for the purpose of Minor Modification 2 is established as the issuance date of Minor Modification 2. The mitigation is required to be implemented by one year from October 20, 2005 which is October 20, 2006. IV.FAILURE TO PROPERLY IMPLEMENT POS�-CONSTRUCTION BMP ➢ Pursuant to 401 Certification 01C-091 Condition 16: • Post-construction Best Management Practices (BMPs) that will be implemented to treat and control urban and storm water runoff ... These BMPs will be implemented and maintained as described in the Water Quality Management Plan (WQMP). California Environmental Protection Agency �a Recycled Paper � Mr. Peter Olah - 3- November 2, 2006 ' Ashby USA, LLC Roripaugh Ranch Residential Development Project • The WQMP says "As much as possible, the 4 detention basins shall be designed to function similar to "constructed wetlands" or "enhanced wet ponds" ... While their primary function is to temporarily detain 100-year storm runoff to prevent down stream impacts, these basins shall also be designed to help maintain local water quality..." Observation: The detention basin outlet design fails to detain and treat the water quality volume and the basin was not designed to function as much as possible like "constructed wetlands" or "enhanced wet ponds." V. FAILURE TO PREVENT DOWNSTREAM EROSION ➢ Pursuant to Pursuant to 401 Certification 01C Condition 16: • These BMPs will be implemented and maintained as described in the WQMP. • The WQMP discusses the potential for development to cause "water traveling at higher speeds which can erode or scour more soil away when it discharges into natural channels." The WQMP also says "Sedimentation and urban pollutants from this development can generally be controlled with a combination of special design features and Best Management Practices (BMPs), most of which control erosion during and after construction. Section F of this report outlines the BMPs recommended for this project." Observation: The detention basin outlet is causing downstream erosion. The WQMP includes only preliminary designs of the basins and not a detailed design of the outlet and erosion control measures, but the intent to control downstream erosion is clear in the WQMP. Erosion control should have been addressed in the final design and installation of the detention basin. ➢ Pursuant to Water Quality Order No. 99-08-DWQ, Section A.5.a.2(c) and A.8: • Temporary on-site drainages to carry concentrated flow shall be selected to - comply with local ordinances, to control erosion, to return flows to their natural drainage courses, and to prevent damage to downstream properties. • The outflow from a sediment basin that discharges into a natural drainage shall be provided with outlet protection to prevent erosion and scour of the embankment and channel. Observations: The detention basin drains areas which are still under construction and could be considered a sediment basin under the General Construction Permit. The basin is temporarily being used to carry concentrated flows from the construction area. There were significant deposits of sediment and erosion observed downstream of the basin. There was scouring of the embankment from erosion caused by low and high velocity flows within the natural waterway down stream of the sediment basin. These effects have the potential to be more pronounced during the wet season. VI. FAILURE TO MAINTAIN AND REPAIR BEST MANAGEMENT PRACTICES (BMPs) TO REDUCE OR ELIMINATE SEDIMENT DISCHARGES IN STORM WATER RUNOFF. ➢ Pursuant to Water Quality Order No. 99-08-DWQ, Section A.11: • Inspections will be performed before and after storm events...to identify BMP effectiveness and implement repairs or design changes as soon as feasible. California Environmental Protection Agency � Recycled Paper Mr. Peter Olah - 4- November 2, 2006 � Ashby USA, LLC Roripaugh Ranch Residential Development Project Observation: The basin is erroneously designed as a flow-through system eliminating sediment settling time. It is probable that offsite storm water discharges from the basin are sediment-laden because the sediment is not allowed to settle before discharging. This is the likely cause of the sediment depositions noted above. ➢ Pursuant to Water Quality Order No. 99-08-DWQ, Section A.8: • The discharger must consider any additional site-specific and seasonal conditions...when designing sediment control BMPs. , Observation: The riprap at the headwall appears ineffective in minimizing downstream erosion. The riprap was covered with sediment eliminating its usefulness in reducing the velocity and energy of concentrated storm water flows from the sediment basin. VII. FAILURE �O PREVENT DISCHARGES OF NON-STORM WATER ➢ Pursuant to Water Quality Order NO. 99-08-DWQ, Special Provision C.3: • Discharges of non-storm water. are authorized only where they do not cause or contribute to a violation of any water quality standard and are controlled through implementation of appropriate BMPs for elimination or reduction of pollutants. Implementation of appropriate BMPs is a condition of authorization of non-storm water discharges. Observations: A discharge from an irrigation pipe break was observed carrying sediment to the storm drain. BMPs were being removed at the time of Regional Board arrival.

FACI��n: Roripauqh Residential Ranch WDID: 9 00001 C091 INSPECTION DATE: August 29, 2006 9 0000512S1 9 33C320657 Introduction On August 29, 2006, Tony Felix and Kristin Schwall conducted a complaint inspection of Ashby USA, LLC Roripaugh Ranch located at 39600 Pourroy Road in Temecula, California. Roripaugh Ranch is regulated under the Statewide General Construction Storm Water Permit, Order No. 9-08-DWQ. The complainant, over a three-year period, claims: (1) significant sediment discharge onto his property at the downgrade perimeter from Roripaugh Ranch's sediment basin and, (2) significant erosion of a tributary (an unnamed tributary to Santa ` Gertrudis Creek), which abuts his property caused by low and high velocity flows from the sediment basin. The complainanYs neighbors also shared similar concerns about sediment discharges onto their property from Roripaugh Ranch's sediment basin, especially during wet season flows. The complainant stated "these effects never occurred before, but started when Roripaugh began construction of the site and started discharging from their sediment basin." Pre-inspection Incident Our 10:00 a.m. arrival at the site was interrupted by a water line break, which occurred at the intersection of Murrieta Hot Springs Road and Pourroy Road (see vicinity map). Gravel bags, which were initially used to confain the pooling sediment-laden water, were being erroneously removed. This allowed the polluted water to flow freely down Murrieta Hot Springs Road (photos 1 and 2). - We immediately alerted the Ashby USA workers that the release of sediment-laden water is strictly prohibited under state regulations and city ordinances. Upon recognizing that we were Regional Board employees, the Ashby workers immediately began replacing the gravel bags to contain the flowing water. By that time there was a significant volume of sediment-laden water discharging along Murrieta Hot Springs Road and entering the storm drain inlet at the intersection of Red Bridge Road (photo 2). The discharge along Murrieta Hot Spring Road occurred for about 30 minutes with approximately 10-20 gallons of sediment-laden water entering the storm drain inlet. Mr. Henry Martinez, Storm Water Pollution Prevention Plan (SWPPP) person for Ashby USA, and his supervisor were present during the incident. Mr. Felix notified Mr. Aldo Licitra, City of Temecula, of the incident. Approximately, fifteen minutes after the discharge occurred, Mr. Henry Martinez had the workers install a series of sediment traps along Murrieta Hot Springs Road to further contain the discharge (photos 3, 4 and 5). Mr. Licitra proposed that the city will conduct a follow up inspection of the incident. He also requested a copy of this inspection report. Complaint Inspection Findinqs At 10:33 a.m., we entered Roripaugh Ranch to walk the site and to inspect the sediment basin.. The basin is at the base of the panhandle of the site, directly behind the club house. The basin, 0.7 acre in size, is designed to capture the stormwater runoff from the "plateau" and the surrounding areas (photos 7 and 9). Close inspection of the basin shows the outlet is level with the base of the basin, making the basin a flow-through system (see photo 8). The basin lacks ' CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD=SAN DIEGO REGION Page 3 of 5 % FAC��N: Roripauqh Residential Ranch WDID: 9 00001 C091 INSPECTION DATE: Auqust 29, 2006 9 0000512S1 9 33C320657 an anchored-riser that would facilitate sediment desilting time. The basin's 6-inch outlet pipe continues through an eighteen-inch pipe and daylights through the headwall located down gradient from the plateau (photo 10). Storm water runoff discharges through riprap, placed at the headwall, to diffuse the high velocity flows from the sediment basin (photo 10). We observed most of the riprap was covered with sediment and therefore, not expected to provide much velocity reduction. In response to the complaints, the City of Temecula had requested more riprap placed at the outlet to further reduce flow velocities from the sediment basin. We traced the path of storm water discharge from the sediment basin's headwall through various private properties to the complainant's property. From the headwall the discharge continues through a grassy swale of a neighbor's backyard through a culvert pipe fitted with � riprap at the inlet (photos 11 and 12). The complainant's property begins down gradient, at the intersection of the culvert pipe outlet and Kimberly Lane. At the culvert pipe outlet, where storm water discharges enter the complainanYs property, we observed severe erosion and sediment deposits within the natural waterway. The erosion effects and sediment deposits were more pronounced in areas along the complainant's property (photos 13 and 15). The natural waterway was scoured in some areas up to about 6 feet high (photo 15). The complainant recalled, "...as a child I could easily walk across the natural waterway." Getting across the tributary is now difficult or impossible because of the depth of erosion gullies that are formed from storm water discharges. We observed significant. amount of erosion, scouring of the embankment, and sediment buildup within the unnamed tributary that abuts the complainant's property and Liefer Road (see photos 16 and 17). Summarv of Construction Storm Water Violations Based on the inspection evidence, it appears that storm water discharges from Roripaugh Ranch's sediment basin is causing erosion and down gradient sediment discharges in prohibition of the general Construction Storm Water Permit, Order No. 99-08-DWQ. 11. 401 CERTIFICATION COMPLIANCE HISTORY 401 Certification No. :01-091 was issued to Ashby USA, LLC for the Roripaugh Ranch Residential Development by the Executive Officer on December 11, 2002. Construction work began during the week of March 10, 2003. 401 Cert Inspection Findings Long Valley Wash has been disturbed from its natural condition as shown in photos 18-23. Ashby USA is in violation of Condition 8 which requires the existing low flow wash of Long Valley Wash to remain in its natural condition, except as detailed in the amended application dated July 25, 2002. The wash should be returned to a natural condition as soon as possible. � CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD-SAN DIEGO REGION Page 4 of 5 - FAC��N: Roripauqh Residential Ranch WDID: 9 00001C091 INSPECTION DATE: Auqust 29, 2006 9 0000512S1 9 33C320657 The concrete bottom of one culvert was noted in Long Valley Wash as shown in photos 24 and 25. Riprap was piled at the downstream side of this culvert awaiting final placement as shown in photo 26. This concrete culvert is authorized under modifications to 401 Certification No. 01 C-091. The cement bottom to another culvert in Santa Gertrudis Creek was being constructed as authorized by modifications to 401 Certification No. 01 C-091. Mitigation for this project has not begun. Ashby USA is in violation of Condition 13 which requires mitigation to be complete within the same calendar year as the impacts or at least no later than 9 months following the close of the calendar year in which the impacts occurred. Impact first occurred in March of 2003 so mitigation was originally required to be complete by September 2004. Minor Modification 2 to the 401 Certification was issued on October 20, 2005. Condition 1 of Minor Modification 2 requires a mitigation plan to be submitted by December 20, 2005. Condition 2 of Minor Modification 2 requires the mitigation plan to be implemented by 1 year from the impacts. The impacts occurred prior to the issuance of Minor Modification 2 on October 20, 2005, so the date of impacts for the purpose of Minor Modification 2 is established as the issuance date of Minor Modification 2. The mitigation is required to be implemented by one year from October 20, 2005, which is October 20, 2006. The mitigation plan is still being negotiated with the resource agencies for impacts to the Nicolas Road Project. Due to the long time between impacts and mitigation, additional mitigation may be necessary. The extended detention basin behind the construction offices on Pourroy Road shown in photos 2 and 3 had mulched and planted slopes. The outlet shown in photo 3 is at the elevation of the basin floor allowing the water to flow straight through without detaining the water quality volume. According to the CASQA guidelines, no more than 50% di the water quality volume should drain from the basin in the first 24 hours. CASQA recommends the use of a riser with an orifice to drain the water quality volume in 72 hours. The County of Riverside's WQMP Design Manual recommends either a perforated riser or a submerged horizontal orifice. This Riverside WQMP Design Manual also states: "The basin outlet is designed to release the design runoff over a 48-hour drawdown period. The drawdown time refers to the minimum amount of time the design volume must be retained. In order to avoid vector breeding problems, the design volume should always empty within 72 hours. To function properly, the outlet must also be sized to retain the first half of the design volume for a minimum of 24 hours." Summarv of 401 Certification Violations This outlet design fails to detain and treat the water quality volume and is in violation of Clean Water Act Section 401 Water Quality Certification No. 01 C-091. Ashby USA is in violation of Condition 16 of 401 Certification No. 01 C-091 which states that post-construction BMPs including detention basins will be implemented to treat and control urban runoff. � CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD—SAN DIEGO REC�ION Page 5 of 5 • FAC��nr: Roripauqh Residential Ranch WDID: 9 00001C091 INSPECTION DATE: Auqust 29, 2006 9 0000512S4 9 33C320657 Photos 11, 12, 13, and 14 show illegal fills of waters of the US downstream of the detention basin. The complainant said that these fill areas were placed to address the erosion from the detention basin discharge. The basin outlet design is causing erosion in the creek downstream from the outlet as shown in photos 8, 10, and 11. Ashby USA is in violation of Condition 16 of 401 Certification No. 01 C-091 for failing to implement BMPs as described in the WQMP. SWPPP Reviewed: YES NO X COPY PROVIDED TO OPERATOR?

The incident occurred the moment we approach the site entrance on Pourroy Road. About an hour later, the Ashby workers had laid out a series of sediment traps along Murrieta Hot Springs Road to contain the sediment discharge. The closest storm drain, located at the intersection on Red Bridge Road, was protected with gravel bags to contain the runoff.
