For example, constraints might include impermeable soils, high groundwater, groundwater pollution or contaminated soils, steep slopes, geotechnical instability, high-intensity land use, heavy pedestrian or vehicular traffic, utility locations or safety concerns. Opportunities might include existing natural areas, low areas, oddly configured or otherwise unbuildable parcels, easements and landscape amenities including open space and buffers (which can double as locations for bioretention BMPs), and differences in elevation (which can provide hydraulic head). Prepare a brief narrative for each of the site optimization strategies described below. This narrative will help you as you proceed with your LID design and explain your design decisions to others. The 2010 Santa Ana MS4 Permit further requires that LID Retention BMPs (Infiltration Only or Harvest and Use) be used unless it can be shown that those BMPs are infeasible. Therefore, it is important that your narrative identify and justify if there are any constraints that would prevent the use of those categories of LID BMPs. Similarly, you should also note opportunities that exist which will be utilized during project design. Upon completion of identifying Constraints and Opportunities, include these on your WQMP Site plan in Appendix 1. Consideration of “highest and best use” of the discharge should also be considered. For example, Lake Elsinore is evaporating faster than runoff from natural precipitation can recharge it. Requiring infiltration of 85% of runoff events for projects tributary to Lake Elsinore would only exacerbate current water quality problems associated with Pollutant concentration due to lake water evaporation. In cases where rainfall events have low potential to recharge Lake Elsinore (i.e. no hydraulic connection between groundwater to Lake Elsinore, or other factors), requiring infiltration of Urban Runoff from projects is counterproductive to the overall watershed goals. Project proponents, in these cases, would be allowed to discharge Urban Runoff, provided they used equally effective filtration-based BMPs. Site Optimization The following questions are based upon Section 3.2 of the WQMP Guidance Document. Review of the WQMP Guidance Document will help you determine how best to optimize your site and subsequently identify opportunities and/or constraints, and document compliance. Did you identify and preserve existing drainage patterns? If so, how? If not, why? Yes – The existing topography of the undeveloped lot sheet flows south, spilling onto Riverside Drive. Final discharge is to the City’s MS4 system. The proposed design will convey roof and site improvement runoff via non-erosive storm drain improvements to WQMP Biofiltration Basins and/or underground storage facilities that include biofiltration treatment prior to discharging from the project site directly to the City’s MS4. Did you identify and protect existing vegetation? If so, how? If not, why? No – site will be cleared and grubbed for grading activities. Did you identify and preserve natural infiltration capacity? If so, how? If not, why? Infiltration is not allowed due to the City’s Highest and Best Use Principle. - 9 - Did you identify and minimize impervious area? If so, how? If not, why? 15% minimum landscape area per Planning Conditions. Landscape was incorporated throughout the site to meet this requirement while maintaining the required parking and other site hardscape features. Did you identify and disperse runoff to adjacent pervious areas? If so, how? If not, why? Yes, all impervious surfaces will be directed to landscaped and biofiltration facilities. - 10 - Section C: Delineate Drainage Management Areas (DMAs) Utilizing the procedure in Section 3.3 of the WQMP Guidance Document which discusses the methods of delineating and mapping your project site into individual DMAs, complete Table C.1 below to appropriately categorize the types of classification (e.g., Type A, Type B, etc.) per DMA for your project site. Upon completion of this table, this information will then be used to populate and tabulate the corresponding tables for their respective DMA classifications. Table C.1 DMA Classifications DMA Name or ID Surface Type(s)12 Area (Sq. Ft.)

Y N If yes has been checked, Infiltration BMPs shall not be used for the site; proceed to section D.3 If no, continue working through this section to implement your LID BMPs. It is recommended that you contact your Co-Permittee to verify whether or not your project discharges to an approved downstream ‘Highest and Best Use’ feature. Geotechnical Report A Geotechnical Report or Phase I Environmental Site Assessment may be required by the Copermittee to confirm present and past site characteristics that may affect the use of Infiltration BMPs. In addition, the Co-Permittee, at their discretion, may not require a geotechnical report for small projects as described in Chapter 2 of the WQMP Guidance Document. If a geotechnical report has been prepared, include it in Appendix 3. In addition, if a Phase I Environmental Site Assessment has been prepared, include it in Appendix 4. Is this project classified as a small project consistent with the requirements of Chapter 2 of the WQMP Guidance Document? Y N Infiltration Feasibility Table D.1 below is meant to provide a simple means of assessing which DMAs on your site support Infiltration BMPs and is discussed in the WQMP Guidance Document in Chapter 2.4.5. Check the appropriate box for each question and then list affected DMAs as applicable. If additional space is needed, add a row below the corresponding answer. Table D.1 Infiltration Feasibility Does the project site… YES NO …have any DMAs with a seasonal high groundwater mark shallower than 10 feet? If Yes, list affected DMAs: …have any DMAs located within 100 feet of a water supply well? If Yes, list affected DMAs: …have any areas identified by the geotechnical report as posing a public safety risk where infiltration of stormwater could have a negative impact? If Yes, list affected DMAs: …have measured in-situ infiltration rates of less than 1.6 inches / hour? If Yes, list affected DMAs: …have significant cut and/or fill conditions that would preclude in-situ testing of infiltration rates at the final infiltration surface? If Yes, list affected DMAs: …geotechnical report identify other site-specific factors that would preclude effective and safe infiltration? Describe here: If you answered “Yes” to any of the questions above for any DMA, Infiltration BMPs should not be used for those DMAs and you should proceed to the assessment for Harvest and Use below. - 13 - D.2 Harvest and Use Assessment Please check what applies: ☐ Reclaimed water will be used for the non-potable water demands for the project. ☐Downstream water rights may be impacted by Harvest and Use as approved by the Regional Board (verify with the Copermittee). ☐The Design Capture Volume will be addressed using Infiltration Only BMPs. In such a case, Harvest and Use BMPs are still encouraged, but it would not be required if the Design Capture Volume will be infiltrated or evapotranspired. If any of the above boxes have been checked, Harvest and Use BMPs need not be assessed for the site. If none of the above criteria applies, follow the steps below to assess the feasibility of irrigation use, toilet use and other non-potable uses (e.g., industrial use). Irrigation Use Feasibility Complete the following steps to determine the feasibility of harvesting stormwater runoff for Irrigation Use BMPs on your site: Step 1: Identify the total area of irrigated landscape on the site, and the type of landscaping used. Total Area of Irrigated Landscape: 0.991 Type of Landscaping (Conservation Design or Active Turf): Conservation Design Step 2: Identify the planned total of all impervious areas on the proposed project from which runoff might be feasibly captured and stored for irrigation use. Depending on the configuration of buildings and other impervious areas on the site, you may consider the site as a whole, or parts of the site, to evaluate reasonable scenarios for capturing and storing runoff and directing the stored runoff to the potential use(s) identified in Step 1 above. Total Area of Impervious Surfaces: 4.872 Step 3: Cross reference the Design Storm depth for the project site (see Exhibit A of the WQMP Guidance Document) with the left column of Table 2-3 in Chapter 2 to determine the minimum area of Effective Irrigated Area per Tributary Impervious Area (EIATIA). Enter your EIATIA factor: 1.85 Step 4: Multiply the unit value obtained from Step 3 by the total of impervious areas from Step 2 to develop the minimum irrigated area that would be required. Minimum required irrigated area: 9.013 Step 5: Determine if harvesting stormwater runoff for irrigation use is feasible for the project by comparing the total area of irrigated landscape (Step 1) to the minimum required irrigated area (Step 4). Minimum required irrigated area (Step 4) Available Irrigated Landscape (Step 1) 9.013 0.991 - 14 - Toilet Use Feasibility Complete the following steps to determine the feasibility of harvesting stormwater runoff for toilet flushing uses on your site: Step 1: Identify the projected total number of daily toilet users during the wet season, and account for any periodic shut downs or other lapses in occupancy: Projected Number of Daily Toilet Users: 600 Project Type: Retail / Office Commercial Step 2: Identify the planned total of all impervious areas on the proposed project from which runoff might be feasibly captured and stored for toilet use. Depending on the configuration of buildings and other impervious areas on the site, you may consider the site as a whole, or parts of the site, to evaluate reasonable scenarios for capturing and storing runoff and directing the stored runoff to the potential use(s) identified in Step 1 above. Total Area of Impervious Surfaces: 4.872 Step 3: Enter the Design Storm depth for the project site (see Exhibit A) into the left column of Table 2-2 in Chapter 2 to determine the minimum number or toilet users per tributary impervious acre (TUTIA).

Minimum number of toilet users: 814 Step 5: Determine if harvesting stormwater runoff for toilet flushing use is feasible for the project by comparing the Number of Daily Toilet Users (Step 1) to the minimum required number of toilet users (Step 4). Minimum required Toilet Users (Step 4) Projected number of toilet users (Step 1) 814 600 Other Non-Potable Use Feasibility Are there other non-potable uses for stormwater runoff on the site (e.g. industrial use)? See Chapter 2 of the Guidance for further information. If yes, describe below. If no, write N/A. N/A Step 1: Identify the projected average daily non-potable demand, in gallons per day, during the wet season and accounting for any periodic shut downs or other lapses in occupancy or operation. Average Daily Demand: Projected Average Daily Use (gpd) Step 2: Identify the planned total of all impervious areas on the proposed project from which runoff might be feasibly captured and stored for the identified non-potable use. Depending on the configuration of buildings and other impervious areas on the site, you may consider the site as a whole, or parts of the site, to evaluate reasonable scenarios for capturing and storing runoff and directing the stored runoff to the potential use(s) identified in Step 1 above. Total Area of Impervious Surfaces: Insert Area (Acres) - 15 - Step 3: Enter the Design Storm depth for the project site (see Exhibit A) into the left column of Table 2-4 in Chapter 2 to determine the minimum demand for non-potable uses per tributary impervious acre. Enter the factor from Table 2-4: Enter Value Step 4: Multiply the unit value obtained from Step 3 by the total of impervious areas from Step 2 to develop the minimum number of gallons per day of non-potable use that would be required. Minimum required use: Minimum use required (gpd) Step 5: Determine if harvesting stormwater runoff for other non-potable use is feasible for the project by comparing the projected average daily use (Step 1) to the minimum required non-potable use (Step 4). Minimum required non-potable use (Step 4) Projected average daily use (Step 1) Minimum use required (gpd) Projected Average Daily Use (gpd) If Irrigation, Toilet and Other Use feasibility anticipated demands are less than the applicable minimum values, Harvest and Use BMPs are not required and you should proceed to utilize LID Bioretention and Biotreatment per Section 3.4.2 of the WQMP Guidance Document. D.3 Bioretention and Biotreatment Assessment Other LID Bioretention and Biotreatment BMPs as described in Chapter 2.4.7 of the WQMP Guidance Document are feasible on nearly all development sites with sufficient advance planning. Select one of the following: ☒ LID Bioretention/Biotreatment BMPs will be used for some or all DMAs of the project as noted below in Section D.4 (note the requirements of Section 3.4.2 in the WQMP Guidance Document). ☐ A site-specific analysis demonstrating the technical infeasibility of all LID BMPs has been performed and is included in Appendix 5. If you plan to submit an analysis demonstrating the technical infeasibility of LID BMPs, request a pre-submittal meeting with the Copermittee to discuss this option. Proceed to Section E to document your alternative compliance measures. - 16 - D.4 Feasibility Assessment Summaries From the Infiltration, Harvest and Use, Bioretention and Biotreatment Sections above, complete Table D.2 below to summarize which LID BMPs are technically feasible, and which are not, based upon the established hierarchy. Table D.2 LID Prioritization Summary Matrix DMA Name/ID LID BMP Hierarchy No LID (Alternative Compliance) 1. Infiltration 2. Harvest and use 3. Bioretention 4. Biotreatment AREA A AREA B AREA C1 AREA C2 AREA D For those DMAs where LID BMPs are not feasible, provide a brief narrative below summarizing why they are not feasible, include your technical infeasibility criteria in Appendix 5, and proceed to Section E below to document Alternative Compliance measures for those DMAs. Recall that each proposed DMA must pass through the LID BMP hierarchy before alternative compliance measures may be considered. Infiltration BMPs are not allowed due to Highest and Best use principles. Harvest and use has been shown to be infeasible. DMA A will incorporate an underground retention system that will either gravity flow or be pumped through a biofiltration cell (or “wetland mod”) connected to the City’s storm drain system. The remaining DMAs will incorporate bioretention and biotreatment. Each bioretention facility will include surface ponding, “engineered” soil mix and a gravel underlayer. Each will also include a 6” perforated underdrain pipe connected to overflow risers connected to the City’s storm drain system. All retention systems and areas will be lined to prevent infiltration. - 17 - D.5 LID BMP Sizing Each LID BMP must be designed to ensure that the Design Capture Volume will be addressed by the selected BMPs. First, calculate the Design Capture Volume for each LID BMP using the VBMP worksheet in Appendix F of the LID BMP Design Handbook. Second, design the LID BMP to meet the required VBMP using a method approved by the Copermittee. Utilize the worksheets found in the LID BMP Design Handbook or consult with your Copermittee to assist you in correctly sizing your LID BMPs. Complete Table D.3 below to document the Design Capture Volume and the Proposed Volume for each LID BMP. Provide the completed design procedure sheets for each LID BMP in Appendix 6. You may add additional rows to the table below as needed.

Where LID BMPs have been demonstrated to be infeasible as documented in Section D, other Treatment Control BMPs must be used (subject to LID waiver approval by the Copermittee). Check one of the following Boxes: ☒ LID Principles and LID BMPs have been incorporated into the site design to fully address all Drainage Management Areas. No alternative compliance measures are required for this project and thus this Section is not required to be completed. - Or - ☐ The following Drainage Management Areas are unable to be addressed using LID BMPs. A site-specific analysis demonstrating technical infeasibility of LID BMPs has been approved by the Co-Permittee and included in Appendix 5. Additionally, no downstream regional and/or sub- regional LID BMPs exist or are available for use by the project. The following alternative compliance measures on the following pages are being implemented to ensure that any pollutant loads expected to be discharged by not incorporating LID BMPs, are fully mitigated. List DMAs here. - 20 - E.1 Identify Pollutants of Concern Utilizing Table A.1 from Section A above which noted your project’s receiving waters and their associated EPA approved 303(d) listed impairments, cross reference this information with that of your selected Priority Development Project Category in Table E.1 below. If the identified General Pollutant Categories are the same as those listed for your receiving waters, then these will be your Pollutants of Concern and the appropriate box or boxes will be checked on the last row. The purpose of this is to document compliance and to help you appropriately plan for mitigating your Pollutants of Concern in lieu of implementing LID BMPs. Table E.1 Potential Pollutants by Land Use Type Priority Development Project Categories and/or Project Features (check those that apply) General Pollutant Categories Bacterial Indicators Metals Nutrients Pesticides Toxic Organic Compounds Sediments Trash & Debris Oil & Grease Detached Residential Development P N P P N P P P Attached Residential Development P N P P N P P P(2) Commercial/Industrial Development P(3) P P(1) P(1) P(5) P(1) P P Automotive Repair Shops N P N N P(4, 5) N P P Restaurants (>5,000 ft2) P N N N N N P P Hillside Development (>5,000 ft2) P N P P N P P P Parking Lots (>5,000 ft2) P(6) P P(1) P(1) P(4) P(1) P P Retail Gasoline Outlets N P N N P N P P Project Priority Pollutant(s) of Concern P = Potential N = Not Potential (1) A potential Pollutant if non-native landscaping exists or is proposed onsite; otherwise not expected (2) A potential Pollutant if the project includes uncovered parking areas; otherwise not expected (3) A potential Pollutant is land use involving animal waste (4) Specifically petroleum hydrocarbons (5) Specifically solvents (6) Bacterial indicators are routinely detected in pavement runoff - 21 - E.2 Stormwater Credits Projects that cannot implement LID BMPs but nevertheless implement smart growth principles are potentially eligible for Stormwater Credits. Utilize Table 3-8 within the WQMP Guidance Document to identify your Project Category and its associated Water Quality Credit. If not applicable, write N/A. Table E.2 Water Quality Credits Qualifying Project Categories Credit Percentage2 Total Credit Percentage1 1Cannot Exceed 50% 2Obtain corresponding data from Table 3-8 in the WQMP Guidance Document E.3 Sizing Criteria After you appropriately considered Stormwater Credits for your project, utilize Table E.3 below to appropriately size them to the DCV, or Design Flow Rate, as applicable. Please reference Chapter 3.5.2 of the WQMP Guidance Document for further information.

Treatment Control BMPs must have a removal efficiency of a medium or high effectiveness as quantified below: • High: equal to or greater than 80% removal efficiency • Medium: between 40% and 80% removal efficiency Such removal efficiency documentation (e.g., studies, reports, etc.) as further discussed in Chapter 3.5.2 of the WQMP Guidance Document, must be included in Appendix 6. In addition, ensure that proposed Treatment Control BMPs are properly identified on the WQMP Site Plan in Appendix 1. Table E.4 Treatment Control BMP Selection Selected Treatment Control BMP Name or ID1 Priority Pollutant(s) of Concern to Mitigate2 Removal Efficiency Percentage3 1 Treatment Control BMPs must not be constructed within Receiving Waters. In addition, a proposed Treatment Control BMP may be listed more than once if they possess more than one qualifying pollutant removal efficiency. 2 Cross Reference Table E.1 above to populate this column. 3 As documented in a Co-Permittee Approved Study and provided in Appendix 6. - 23 - Section F: Hydromodification F.1 Hydrologic Conditions of Concern (HCOC) Analysis Once you have determined that the LID design is adequate to address water quality requirements, you will need to assess if the proposed LID Design may still create a HCOC. Review Chapters 2 and 3 (including Figure 3-7) of the WQMP Guidance Document to determine if your project must mitigate for Hydromodification impacts. If your project meets one of the following criteria which will be indicated by the check boxes below, you do not need to address Hydromodification at this time. However, if the project does not qualify for Exemptions 1, 2 or 3, then additional measures must be added to the design to comply with HCOC criteria. This is discussed in further detail below in Section F.2. HCOC EXEMPTION 1: The Priority Development Project disturbs less than one acre. The Copermittee has the discretion to require a Project-Specific WQMP to address HCOCs on projects less than one acre on a case by case basis. The disturbed area calculation should include all disturbances associated with larger common plans of development. Does the project qualify for this HCOC Exemption? Y N If Yes, HCOC criteria do not apply. HCOC EXEMPTION 2: The volume and time of concentration1 of storm water runoff for the post- development condition is not significantly different from the pre-development condition for a 2-year return frequency storm (a difference of 5% or less is considered insignificant) using one of the following methods to calculate: • Riverside County Hydrology Manual • Technical Release 55 (TR-55): Urban Hydrology for Small Watersheds (NRCS 1986), or derivatives thereof, such as the Santa Barbara Urban Hydrograph Method • Other methods acceptable to the Co-Permittee Does the project qualify for this HCOC Exemption? Y N If Yes, report results in Table F.1 below and provide your substantiated hydrologic analysis in Appendix 7. Table F.1 Hydrologic Conditions of Concern Summary 2 year – 24 hour Pre-condition Post-condition % Difference Time of Concentration INSERT VALUE INSERT VALUE INSERT VALUE Volume (Cubic Feet) INSERT VALUE INSERT VALUE INSERT VALUE 1 Time of concentration is defined as the time after the beginning of the rainfall when all portions of the drainage basin are contributing to flow at the outlet. - 24 - HCOC EXEMPTION 3: All downstream conveyance channels to an adequate sump (for example, Prado Dam, Lake Elsinore, Canyon Lake, Santa Ana River, or other lake, reservoir or naturally erosion resistant feature) that will receive runoff from the project are engineered and regularly maintained to ensure design flow capacity; no sensitive stream habitat areas will be adversely affected; or are not identified on the Co-Permittees Hydromodification Susceptibility Maps. Does the project qualify for this HCOC Exemption? Y N If Yes, HCOC criteria do not apply and note below which adequate sump applies to this HCOC qualifier: Lake Elsinore F.2 HCOC Mitigation If none of the above HCOC Exemption Criteria are applicable, HCOC criteria is considered mitigated if they meet one of the following conditions: a. Additional LID BMPS are implemented onsite or offsite to mitigate potential erosion or habitat impacts as a result of HCOCs. This can be conducted by an evaluation of site-specific conditions utilizing accepted professional methodologies published by entities such as the California Stormwater Quality Association (CASQA), the Southern California Coastal Water Research Project (SCCRWP), or other Co-Permittee approved methodologies for site-specific HCOC analysis. b. The project is developed consistent with an approved Watershed Action Plan that addresses HCOC in Receiving Waters. c. Mimicking the pre-development hydrograph with the post-development hydrograph, for a 2- year return frequency storm. Generally, the hydrologic conditions of concern are not significant, if the post-development hydrograph is no more than 10% greater than pre-development hydrograph. In cases where excess volume cannot be infiltrated or captured and reused, discharge from the site must be limited to a flow rate no greater than 110% of the pre- development 2-year peak flow. Be sure to include all pertinent documentation used in your analysis of the items a, b or c in Appendix 7. - 25 - Section G: Source Control BMPs Source control BMPs include permanent, structural features that may be required in your project plans — such as roofs over and berms around trash and recycling areas — and Operational BMPs, such as regular sweeping and “housekeeping”, that must be implemented by the site’s occupant or user. The MEP standard typically requires both types of BMPs. In general, Operational BMPs cannot be substituted for a feasible and effective permanent BMP. Using the Pollutant Sources/Source Control Checklist in Appendix 8, review the following procedure to specify Source Control BMPs for your site: 1. Identify Pollutant Sources: Review Column 1 in the Pollutant Sources/Source Control Checklist. Check off the potential sources of Pollutants that apply to your site. 2. Note Locations on Project-Specific WQMP Exhibit: Note the corresponding requirements listed in Column 2 of the Pollutant Sources/Source Control Checklist. Show the location of each Pollutant source and each permanent Source Control BMP in your Project-Specific WQMP Exhibit located in Appendix 1. 3. Prepare a Table and Narrative: Check off the corresponding requirements listed in Column 3 in the Pollutant Sources/Source Control Checklist. In the left column of Table G.1 below, list each potential source of runoff Pollutants on your site (from those that you checked in the Pollutant Sources/Source Control Checklist). In the middle column, list the corresponding permanent, Structural Source Control BMPs (from Columns 2 and 3 of the Pollutant Sources/Source Control Checklist) used to prevent Pollutants from entering runoff. Add additional narrative in this column that explains any special features, materials or methods of construction that will be used to implement these permanent, Structural Source Control BMPs. 4. Identify Operational Source Control BMPs: To complete your table, refer once again to the Pollutant Sources/Source Control Checklist. List in the right column of your table the Operational BMPs that should be implemented as long as the anticipated activities continue at the site. Copermittee stormwater ordinances require that applicable Source Control BMPs be implemented; the same BMPs may also be required as a condition of a use permit or other revocable Discretionary Approval for use of the site.

Co-Permittee staff can advise you regarding the process required to propose changes to the approved Project-Specific WQMP. -28 - Section I: Operation, Maintenance and Funding The Copermittee will periodically verify that Stormwater BMPs on your site are maintained and continue to operate as designed. To make this possible, your Copermittee will require that you include in Appendix 9 of this Project-Specific WQMP: 1.A means to finance and implement facility maintenance in perpetuity, including replacement cost. 2.Acceptance of responsibility for maintenance from the time the BMPs are constructed until responsibility for operation and maintenance is legally transferred. A warranty covering a period following construction may also be required. 3.An outline of general maintenance requirements for the Stormwater BMPs you have selected. 4.Figures delineating and designating pervious and impervious areas, location, and type of Stormwater BMP, and tables of pervious and impervious areas served by each facility. Geo- locating the BMPs using a coordinate system of latitude and longitude is recommended to help facilitate a future statewide database system. 5.A separate list and location of self-retaining areas or areas addressed by LID Principles that do not require specialized O&M or inspections but will require typical landscape maintenance as noted in Chapter 5, pages 85-86, in the WQMP Guidance. Include a brief description of typical landscape maintenance for these areas. Your local Co-Permittee will also require that you prepare and submit a detailed Stormwater BMP Operation and Maintenance Plan that sets forth a maintenance schedule for each of the Stormwater BMPs built on your site. An agreement assigning responsibility for maintenance and providing for inspections and certification may also be required. Details of these requirements and instructions for preparing a Stormwater BMP Operation and Maintenance Plan are in Chapter 5 of the WQMP Guidance Document. Maintenance Mechanism: Stormwater Management Facilities Operations and Maintenance Agreement and Right of Entry. All BMPs to be maintained by POA. Will the proposed BMPs be maintained by a Home Owners’ Association (HOA) or Property Owners Association (POA)? Y N Include your Operation and Maintenance Plan and Maintenance Mechanism in Appendix 9.

The purposes of the investigation were to: 1) determine the type and condition of the soil materials at the site; 2) establish static physical and limited chemical properties of the materials; 3) determine groundwater conditions; and 4) provide recommendations for design and construction of the building foundations and floor slabs for the proposed convenience store, fuel canopy and fast food, car wash and self-storage buildings and pavement design for the associated parking lot. SCOPE OF WORK The scope of work for this geotechnical investigation consisted of the following: Review of published regional geologic maps and reports (See References). A field exploration was conducted on February 25, 2020 and consisted of drilling, logging, and sampling seven exploratory borings (B-1 to B-7) to depths of up to 21.5 feet. The field exploration is described in detail in Appendix A. Two percolation tests to establish an infiltration rate were performed as part of the investigation. The tests were conducted in borings I-1 and I- 2. The results are discussed in Appendix D. Selected samples were tested in HGEI’s AMRL Accredited Geotechnical Laboratory to develop data necessary for analysis of subsurface conditions and used in preparation of this report. A description of the geotechnical laboratory testing conducted for the samples collected from the site and presentation of the results are found in the Laboratory Procedures & Test Results in Appendix B. HGEI conducted engineering analysis, constructed figures, and prepared this report depicting the findings and conclusions of the investigation. SITE LOCATION AND DESCRIPTION The site is located at 15209 Lincoln Street, Lake Elsinore, CA as shown on the Vicinity Map, Figure 1, which follows. As shown on the Air Photo, Figure 2, the relatively flat pad is bordered on the southeast by Riverside Drive, to the northeast by Lincoln Street, to the northwest by GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 2 1590 N.

The lot is currently vacant and covered with grass and scattered trees. Vicinity Map - Figure 1 Air Photo-Figure 2 GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 3 1590 N. Brian Street, Orange, CA 92867-3406 FAX (714) 637-3096 PHONE (714) 637-3093 Please visit our website at www.harringtongeotechnical.com PROJECT DESCRIPTION As shown on Plate A, the new development will be comprised of several single-story buildings that will be a convenience store, fast food, car wash and self-storage facility, a fuel canopy and associated parking lot. Minimal grade changes are anticipated. The building foundations will comprise continuous perimeter foundation with slab on grade floors. Typical single-story foundation loads, about 1,500 pounds per lineal foot have been considered in preparation of this report. The fuel canopy will be supported on reinforced concrete piers, supporting maximum vertical loads in the order of 10 kips. REGIONAL GEOLOGIC SETTING The subject site is situated along the central portion of the Peninsular Ranges Geomorphic Province of Southern California within the Elsinore extensional structural basin created by movements along the Elsinore fault zone. The Peninsular Ranges Geomorphic Province is characterized by elongated northwest to southeast trending ridges and valleys subparallel to faults branching from the San Andreas Fault. Published maps (Reference 4) have been used to identify the geologic unit underlying the property. As shown on Figure 3, these maps indicate that the property is underlain at depth by young alluvial valley deposits of Holocene to late Pleistocene geologic age. Regional Geologic Map - Figure 3 Qyva – Young Alluvial Valley Deposits (Holocene and late Pleistocene) — Silty to sandy alluvium on valley floors; gray, unconsolidated SITE GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 4 1590 N. Brian Street, Orange, CA 92867-3406 FAX (714) 637-3096 PHONE (714) 637-3093 Please visit our website at www.harringtongeotechnical.com SUBSURFACE CONDITIONS Earth Materials Subsurface conditions encountered during this investigation are described in more detail in Appendix A. Logs of the borings are presented on Plates A-1 and A-7 and show the site to be immediately underlain by alluvial material comprised of silty sand to sandy silt that is damp to moist and moderately dense. Groundwater Groundwater was not encountered at the time of drilling. A groundwater monitoring well located approximately .75 miles northeast of the site and identified as State Well Number 6S05W02A001S indicates a groundwater depth of 298 feet below the ground surface recorded on 11/12/19 (Reference 3). Groundwater levels can fluctuate but groundwater is not expected to adversely affect the proposed development under normal conditions in the future. Caving Caving of the exploratory borings did not occur due to the types of soil encountered and is not expected to be a major concern during construction. The regulations of Cal/OSHA should be complied with during performance of all underground construction. Expansion Potential Based on the results of laboratory testing (Table 1, Appendix B) the Expansion Index for the typical near-surface material is 10. The 2019 California Building Code (Section 1803.5.3) categorizes this material as being non-expansive and special design is not required per Section 1808.6. Water-Soluble Sulfate A soil sample was delivered to a state approved analytical laboratory for testing to evaluate water-soluble sulfate content. Based on the results of laboratory testing (Table 2, Appendix B) a negligible (S0) exposure category is indicated (ACI 318, Table 4.2.1). GEOLOGIC HAZARDS Faulting/Fault Rupture The site is in a portion of California that is seismically active and anticipated to be subjected to strong ground motions by earthquakes generated by active faults in the area. The site is not GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 5 1590 N. Brian Street, Orange, CA 92867-3406 FAX (714) 637-3096 PHONE (714) 637-3093 Please visit our website at www.harringtongeotechnical.com within a presently designated earthquake fault zone as established by the Alquist-Priolo Fault Zoning Act (Reference 1). The site is situated approximately 1.1 km from the nearest fault (Elsinore Glen Ivy) and 5.5 km from the next nearest fault (Elsinore-Temecula). The likelihood of surface rupture occurring at the site is considered low. Liquefaction/Seismically Induced Settlement The site has not been evaluated by California Geological Survey (CGS) for liquefaction hazard potential (Reference 1). The City of Lake Elsinore General Plan (Reference 3) indicates that the site is underlain by sediments that are moderately susceptible to liquefaction. Based on this classification and the depth to groundwater, a liquefaction/dry sand settlement assessment was not considered necessary. CONCLUSIONS AND RECOMMENDATIONS Based on conditions encountered/established during this investigation, it is our conclusion that construction of the currently planned convenience store, fuel canopy and fast food, car wash and self-storage buildings and associated parking lot is feasible from a geotechnical engineering standpoint provided the recommendations which follow are implemented during design and construction of the project. Following our evaluation of conditions encountered in the field exploration and the analyses of laboratory test data, the following recommendations for grading the site and designing the footings, at-grade floor slabs and pavement section are being provided. Anticipated conditions and these recommendations are subject to confirmation during construction. Additional recommendations may be provided during the course of work if warranted by conditions encountered. The foundation plan should be reviewed by the geotechnical engineer and any necessary recommendations provided in a review letter. Site Clearing and Grading It is recommended that grading be carried out in accordance with applicable sections of the Grading Specifications in Appendix E and the following site specific recommendations. Prior to grading, any existing vegetation should be stripped and disposed of offsite according to the city’s requirements. GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 6 1590 N. Brian Street, Orange, CA 92867-3406 FAX (714) 637-3096 PHONE (714) 637-3093 Please visit our website at www.harringtongeotechnical.com In order to develop adequate uniform support and alleviate the potential for differential settlement, the soil in the new structure areas plus five feet in each direction, should be removed to a minimum depth of 3 feet, or to the depth necessary to expose competent soil, the exposed soil scarified 12 inches deep, moisture conditioned to optimum moisture content, and compacted to a minimum relative compaction of 90% based on the results of compaction tests performed in accordance with ASTM Test Method D1557-12ɛ1. New hardscape areas should be scarified 12 inches deep, and moisture conditioned and compacted as indicated above. New parking and drive areas should be over-excavated one foot deep, scarified 12 inches deep, and moisture conditioned and compacted as indicated above. Replacement fill material should be spread in thin, loose lifts, and moisture conditioned and compacted as indicated above. Imported soil shall be approved by the geotechnical engineer for expansion, sulfate, and strength qualities prior to being transported to the project site. Final acceptance of any imported soil will be based on observation and/or testing of soil actually delivered to the site. It is recommended that grading operations be monitored by a representative of this office in order to confirm compliance with these recommendations and, in turn, the foundation design recommendations which follow. Seismic Design The provisions of Chapter 16, Section 1613, of the 2019 California Building Code and the Structural Engineer Associates of California guidelines are considered appropriate for design of the project. Earthquake factors determined using the SEAOC/OSHPD data base website and Chapter 16 requirements are presented in Appendix C. Fuel Canopy Foundation Design An allowable, net, vertical bearing pressure of 3,000 pounds per square foot is recommended for design of 18-inch-diameter, or larger, piers at least 6 feet deep. This pressure may be increased by 600 pounds per square foot for each additional foot of embedment up to 5000 pounds per square foot. An allowable lateral bearing pressure of 300 pounds per square foot per foot of depth limited to 2,000 pounds per square foot is recommended. GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 7 1590 N. Brian Street, Orange, CA 92867-3406 FAX (714) 637-3096 PHONE (714) 637-3093 Please visit our website at www.harringtongeotechnical.com Minor caving/raveling may occur. Concrete should be placed as soon as possible to minimize this occurrence. Building Foundation Design New conventional footings embedded into approved fill material may be used. Footings with a minimum width of 12 inches and plan dimension depth of 18 inches (measured from the lowest adjacent finish grade) may be designed using an allowable, net, dead load plus live load soil bearing pressure up to 2,000 pounds per square foot (psf). The allowable soil bearing pressure can be increased by 250 psf for each additional foot of width or depth to a maximum allowable bearing capacity of 3,000 psf if deemed necessary by the structural engineer. A one-third increase in bearing may be assumed for short duration wind or seismic loading in combination with vertical loads. Minimum reinforcement recommended for any continuous footings is one No. 4 bar, top and bottom. Pad footing reinforcement, if any, will be governed by structural design. For the purposes of resisting lateral forces, an allowable passive soil pressure of 300 pounds per square foot per foot of depth may be used in design. A coefficient of friction of 0.35 may be used for concrete placed on approved compacted fill. These values may be combined without reduction. It is recommended that the foundation excavations be examined and, if necessary, tested by a representative of the geotechnical engineer to confirm anticipated conditions and/or provide additional recommendations should they be necessary. Floor Slab Design/Construction It is recommended that the floor slab be a nominal 4 inches thick, reinforced with No. 4 bars at 24 inches on center, each way. A moisture vapor retarder installed in accordance with the manufacturer’s instructions should be provided. We would recommend that 2 inches of clean sand be placed over a minimum 10 mil visqueen vapor barrier underlain by 4 inches of coarse sand or gravel to comply with the requirements of CALGREEN. HGEI does not practice in the field of moisture vapor transmission evaluation/mitigation. Therefore, we recommend that a qualified consultant be engaged with to evaluate the general and specific moisture vapor transmission paths and any impact on the proposed construction. GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 8 1590 N. Brian Street, Orange, CA 92867-3406 FAX (714) 637-3096 PHONE (714) 637-3093 Please visit our website at www.harringtongeotechnical.com This consultant should provide recommendations for mitigation of potential adverse impact of moisture vapor transmission on various components of the structure as deemed appropriate. Settlement Foundation settlement (total and differential) should not exceed ½-inch and ¼-inch, respectively. The horizontal distance over which differential settlement could occur is 20 feet. Concrete Flatwork/Driveway Miscellaneous flatwork should be a nominal 4 inches thick, reinforced at mid-depth with No 4 bars at 24 inches on center each way and provided with adequate control joints. Low slump concrete should be used for all flatwork to further minimize cracking. The driveway thickness should be 5 inches if constructed of concrete. It should be noted that due to normal concrete shrinkage some minor cracking of the concrete flatwork may occur. Additional reinforcement beyond that recommended herein and careful control of concrete slump would be beneficial in reducing such cracking. Also, it is very important that all control joints be caulked and properly maintained to inhibit infiltration of surface water into the soil and thereby minimize expansion. Pavement Based on an estimated R-value of 40 and assumed Traffic Index of 4.5 for parking areas, it is recommended that automobile traffic areas be paved with 4 inches of asphalt concrete over 4 inches of Class II Base and automobile drive lanes with an assumed Traffic Index of 5 should be paved with 5 inches of asphalt concrete over 4 inches of Class II base. The sections should be placed on a minimum of two feet of soil compacted to at least 90 percent of the maximum dry density determined in accordance with ASTM Test Method D1557. (Ref. Caltrans Highway Design Manual Chapter 630). As an alternative, based on an estimated R-value of 40 and assumed Traffic Index of 5, asphalt parking and drive lanes could be paved with a full depth section with 0.60 foot of asphalt concrete placed on a minimum of two foot of compacted soil. The foot immediately beneath the asphalt should be compacted to at least 95 percent of the maximum dry density determined in accordance with ASTM Test Method D1557. The other lower foot should be compacted to at least 90 percent of the maximum dry density determined in accordance with ASTM Test Method D1557.

The exposure class (ACI 318-11, Table 4.2.1) is S0. Based on this test result concrete may contain Type II cement (Section 1904.2 of the 2019 CBC and ACI 318, Section 4.3, Table 4.3.1). Site Drainage The 2019 CBC Section 1804.4 requires that the minimum drainage for the ground around the perimeter of a building should be 5% away from the foundation for a distance of 10 feet. Impervious surfaces within 10 feet of the building foundation shall be sloped a minimum of 2%. In no case should the surface waters be allowed to flow over the slope surfaces in an uncontrolled manner. Utility Trench Backfills Backfill for any trenches associated with this project should consist of site and/or similar material (the use of imported sand is not recommended) that must be adequately compacted to preclude detrimental settlement. It is recommended, therefore, that backfills placed below the building foundation and to a distance of five feet outside thereof, and below concrete flatwork, be placed in appropriate lifts, moisture conditioned and mechanically compacted to at least 90 percent of maximum dry density. Plan Review It is recommended that final project plans, details and specifications be submitted to this office for geotechnical review for compliance with the findings and recommendations of this report. Additional recommendations can then be provided if necessary. Grading Observations and Testing Grading and foundation construction should be observed and tested by members of our staff so that anticipated soil conditions can be confirmed and the recommendations contained herein validated. If deemed necessary, as a result of changed conditions, supplemental recommendations may then be provided. Results of those observations and tests should be provided in the final report which should include a statement by the geotechnical engineer concerning the adequacy of the completed work. Pre-Construction Meeting A pre-grade/construction meeting should be attended by the owner’s representative, members of the design team, grading contractor, city/county inspector, and a representative from HGEI GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 10 1590 N.

Brian Street, Orange, CA 92867-3406 FAX (714) 637-3096 PHONE (714) 637-3093 Please visit our website at www.harringtongeotechnical.com The field investigation was conducted on February 25, 2020 and consisted of logging and sampling seven exploratory borings drilled with a truck mounted hollow stem 8-inch-diameter auger to depths of up to 21.5 feet. The subsurface exploration locations are indicated on Plate A and the logs of the borings are presented on Plates A-1 to A-7. Two additional borings (I-1 and I-2) were drilled for percolation testing to establish an infiltration rate. The results are discussed in Appendix D. The descriptions represent the prevalent soil types and slightly different material types may be present within the major groupings. Also, the transition from one soil type or condition to another may be gradual rather than abrupt as implied, and differing conditions may exist in unexplored areas. Unified Soil Classification System Classification Criteria/Symbols are presented on Plate A-8. A representative of the geotechnical engineer observed the field work, collected samples for transportation to our geotechnical laboratory, and prepared field logs by visual/tactile examination of the materials. Core samples were obtained at discreet intervals using a modified California split-spoon sampler loaded with 2.42” I.D. x 1”-long, thin-wall, brass rings. Bulk samples of the materials were also collected. Samples were placed in plastic bags immediately upon removal from the sampler to conserve moisture and labeled for identification. The borings were backfilled with excavated soils immediately upon completion of sampling. Groundwater was not encountered at the time of drilling the borings. 1590 N.

Tests were performed in general accordance with latest ASTM standards. The following is a description of the laboratory testing and presents the results which are incorporated in the previous sections of the report. Moisture and Density Determination (ASTM D2216-10 & D7263-09) Field Moisture contents were determined for all samples. The core samples were trimmed and weighed and the dry densities of the material calculated. Moisture and dry density data are presented on the logs in Appendix A. Expansion Index Test (ASTM D4829-11) An Expansion Index Test was conducted on a sample considered representative of the site material to establish data on which to base recommendations for foundation design. The test result is presented in Table 1. Water-Soluble Sulfate Tests (EPA 300.0) In order to determine the proper cement type for the site, the amount of water-soluble sulfate present in a selected sample of the surface material was determined. The test result is presented in Table 2. Compaction Test (ASTM D1557-12ɛ1) Compaction tests were performed on samples of surface soil to develop values for initial use during grading and backfilling work. The results are presented in Table 3. Direct Shear Direct Shear tests were performed on undisturbed specimens to determine the static strength of the soils. The tests were performed at increased moisture contents and at various confining pressures using a displacement rate of 0.0012 in./min. to establish peak and ultimate strength parameters under adverse conditions of moisture. Results are presented on Plates B-1 to B-4. Consolidation Consolidation tests were performed on undisturbed samples to determine the magnitude and rate of consolidation of the soil when subjected to incrementally applied controlled-stress loading. Graphs of the test results are presented on Plates B-5 to B-7. GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 16 1590 N.

Brian Street, Orange, CA 92867-3406 FAX (714) 637-3096 PHONE (714) 637-3093 Please visit our website at www.harringtongeotechnical.com Scope of Services In order to establish infiltration rates, the following was conducted: Equipment and personnel were provided to conduct two borehole infiltrometer tests at the locations shown on Plate A in accordance with Appendix A of the Riverside County Low Impact Development BMP Design Manual. The tests were conducted at depth of approximately 5 feet below ground surface on February 26, 2020. The data is attached on Percolation Data Sheets I-1 & I-2. Upon completion of the testing, the data was analyzed, appropriate engineering calculations were performed, and this report was prepared. Infiltration Rate Our interpretation of the results indicate a tested infiltration rate of 2.06 in/hr. for I-1 at a depth of 51 inches and a tested infiltration rate of 1.85 in/hr. for I-2 at a depth of 48 inches. The measured infiltration rate needs to exceed 0.3 in/hr. for the area to be considered potentially feasible. Table 1 of Appendix A also has a factor of safety based on Suitability Assessment and Design. We have listed our interpretation of how those values should be applied. The factor of safety would be 3. The design infiltration rate would be 0.69 in/hr for I-1 and 0.62 in/hr for I-2 Soil Types The site materials are mainly silty sand (SM). Groundwater Groundwater was not encountered in the deepest borings at 21.5 feet for the geotechnical investigation conducted in February 25, 2020. The recorded nearby groundwater depth is 298 feet (Reference 3). 1590 N.

When applicable, the Contractor may obtain the approval of the Project Geotechnical Engineer and the controlling authorities for the project to dispose of the above-described materials, or a portion thereof, in designated areas onsite. 2.2. The exposed surfaces in areas to receive fill shall be scarified to a depth specified by the geotechnical report or a nominal 6 inches as determined by the Project Geotechnical Engineer; moisture conditioned as necessary; and compacted. In areas where it is necessary to obtain the approval of the controlling agency prior to placing fill, it will be the Contractor's responsibility to arrange the required inspections. 2.3. Any underground structures, e.g. cesspools, cisterns, septic tanks, wells, pipelines, etc., encountered during the grading operation are to be removed or relocated and the ground prepared for fill (cut) in a proper manner as recommended by the Project Geotechnical Engineer and/or the controlling agency for the project. 3. Subdrains 3.1. All subdrains should be constructed below the fill areas. Horizontal subdrains should be constructed below sloping fill areas at approximate 30 feet vertical intervals. Typical subdrains (less than 300 linear feet in length) should of constructed of 4-inch-diameter, perforated, Schedule 40 PVC pipe surrounded by one cubic foot per linear foot of gravel and filter fabric. Canyon subdrains should consist of 8-inch-diameter, perforated, Schedule 40 PVC pipe surrounded by nine cubic feet per linear foot of approved gravel wrapped with filter fabric. 4. Compacted Fills/Fill Slopes 4.1. All material imported to the grading operation should be reviewed by the Project Geotechnical Engineer for compatibility prior to placement as fill. Laboratory testing of import materials may be required as recommended by the Project Geotechnical Engineer. Import materials deemed unacceptable for placement of fill should be removed from the fill areas and disposed of offsite of the grading operation. 4.2. All rock or rock fragments less than 8 inches in size should be incorporated into fill in a manner which will prevent nesting and the rock/rock fragments are completely surrounded with compacted fill. 4.3. All rocks greater than 8 inches in size shall be removed from the project site or placed in accordance with the recommendations of the Project Geotechnical Engineer and controlling agency code in areas designated as suitable for rock disposal. 4.4. All fill materials shall be placed in thin loose lifts, moisture conditioned as necessary and compacted in accordance with project specifications.

All wet materials proposed for placement in fill areas should be moisture conditioned as necessary (either air dried or mechanically mixed). The Project Geotechnical Engineer may recommend removal of materials deemed too wet for placement of fill. 4.6. All fills shall be compacted to minimum project standards in compliance with the testing methods specified in the geotechnical report and in accordance with recommendations of the Project Geotechnical Engineer. Unless otherwise specified, the compaction standard shall be ASTM D1557 (latest approved standard). 4.7. All proposed slopes receiving fill (or ground sloping in excess of a ratio of five horizontal to one vertical), the fill shall be keyed and benched through all unsuitable topsoil, colluvium, alluvium, or creep-prone material into competent bedrock in accordance with the recommendations and approval of the Project Geotechnical Engineer or Project Engineering Geologist. 4.8. All drainage terraces for proposed fill slopes shall be constructed in compliance with the approved Grading Plan and/or the recommendations of the Project Civil Engineer. The preparation of the ground for construction of the drainage terraces should be reviewed for suitability by the Project Geotechnical Engineer. 4.9. All fill slopes (including buttresses and stabilization fills) shall be graded to a ratio not to exceed two horizontal to one vertical. The Contractor shall be required to obtain the specified minimum relative compaction out to the proposed finish slope face of slope. This may be achieved by both overbuilding the slope and cutting back to expose the compacted core, or by direct compaction of the slope face with suitable equipment, or by any other procedure which produces the designated result. 5. Keying and Benching 5.1. All fill-over-cut slopes shall be properly keyed through topsoil, colluvium or creep-prone material into bedrock or other firm material, and the transition shall be stripped of all unsuitable materials prior to placing fill. See the Keying and Benching Detail, Figure 1. The cut portion should be completed and then evaluated by the Project Engineering Geologist prior to placement of fill. The minimum dimensions of the key should be determined by the Project Engineering Geologist. All keys should include a subdrain as specified in Section 3.

All drainage terraces for proposed cut slopes and shall be constructed in compliance with the approved Grading Plan and/or the recommendations of the Project Civil Engineer. The preparation of the ground for construction of the drainage terraces should be reviewed for suitability by the Project Geotechnical Engineer. 7. Retaining Wall Backfill 7.1. Retaining wall backfill should include a 12” wide blanket of granular soil (with a sand equivalent of at least 30) above a constructed subdrain and extend to within 3 feet of finished grade. The top 3 feet of backfill should consist of site material compacted to at least 90 percent relative compaction to impede surface water infiltration. Benches at least 2 feet wide should be cut into the excavation slope (backcut) at 2-foot vertical intervals during backfill placement. 7.2. The subdrain should consist of a 3-inch-diameter, perforated, Schedule 40 PVC or ABS SDR-35 pipe surrounded by one cubic foot/foot of 3/4-inch gravel wrapped in Mirafi 140 N geofabric or similar product. An adequate outlet for the subdrain should be provided and the location of the subdrain outlet should be reviewed by the project geotechnical engineer (engineering geologist) for suitability. 8. Utility Trench Backfills 8.1. Backfill for utility trenches should consist of site material that must be adequately compacted to preclude detrimental settlement. It is recommended, therefore, that backfills placed below the building foundation and to a distance of five feet outside thereof, and/or below concrete flatwork, be placed in appropriate lifts, moisture conditioned as necessary and mechanically compacted as to at least 90 percent of maximum dry density. Import materials (including sand) should be reviewed by the Project Geotechnical Engineer for suitability. 9. Grading Observations 9.1. Grading operations shall be observed by the Project Geotechnical Engineer (Geotechnical Technician) and where required, the Project Engineering Geologist. 9.2. All field density tests shall be made by the Geotechnical Technician to establish the relative compaction and moisture content of the fill in accordance with project specifications. Density tests shall generally be performed at (minimum) intervals not to exceed of 2 vertical feet or 1,000 cubic yards of material placed. 9.3. All field density testing of fill placed during the grading operation shall conform to the minimum project specifications. When test results indicate that the density of any layer of fill, or portion thereof, is below the required relative compaction (or outside the acceptable moisture range); the fill shall be reworked until the required density and/or GOLCHEH GROUP HGEI Project No: 20-01-3952 March 13, 2020 Page 26 1590 N.

Phase I Environmental Site Assessment (ESA) conducted by GEM Group, Inc (GEM) at 15209 Lincoln Street, Lake Elsinore, CA 92530 (see Figures 1 and 2). The Phase I ESA, Project No. 19-9351, was conducted in accordance with GEM’s Standard Terms and Conditions. The findings and conclusions of this Phase I ESA are based on the information collected and available during the timeframe of this project. GEM has performed this Phase I ESA of the subject property in conformance with the scope and limitations of the Environmental Protection Agency, Standards and Practices for All Appropriate Inquiries, 40 CFR Part 312 and the standard practice set forth in the American Society for Testing and Materials (ASTM) Designation: E1527-13, "Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process." Any exceptions to, or deletions from, these practices are described in Section 1.2 of this report. The subject property is a 6.23-acre vacant dirt lot with weeds and trees. Historical sources show the subject property developed with multiple structures along the northeast corner from at least 1938 until 1987 when it appears the structures were demolished. The remainder of the subject property was part of an orchard. The onsite orchard appears to have been abandoned and allowed to die prior to the 1980s. The subject property appears to have been undeveloped since at least 1987. The subject property is not listed in the regulatory databases reviewed. There were no records from various regulatory agencies that identify the potential for adverse environmental impact from the subject and adjoining properties. There are no listed offsite listings with the potential for adverse environmental impact on the subject property. There are no recognized environmental conditions (RECs) identified at the subject property. A REC refers to the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. Given the findings and conclusions of this Phase I ESA, GEM recommends no further investigation at this time. However, if the subject property is redeveloped for residential use, then soil sampling may be required to determine the presence of pesticides from former orchard use. 1-1 Project No. 19-9351 1.0 INTRODUCTION The purpose of this Phase I Environmental Site Assessment (ESA) is to assess (1) the likelihood of contamination at the subject property as a result of either past or present land-use practices; and (2) the potential for future environmental contamination which may occur as a result of current conditions or operations and maintenance activities at either the subject property or properties adjoining the subject property, thereby identifying real or potential environmental or economic impact to the subject property. In this way, the client may satisfy a requirement to qualify for the innocent landowner defense to the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) liability by completing "all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial and customary practice." 1.1 SCOPE OF WORK To meet the objectives stated above, GEM has performed this Phase I ESA of the subject property in conformance with the scope and limitations of the Environmental Protection Agency, Standards and Practices for All Appropriate Inquiries, 40 CFR Part 312 and the standard practice set forth in the American Society for Testing and Materials (ASTM) Designation: E1527-13, "Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process." Any exceptions to or deletions from these practices are described in Section 1.2. The scope of work for the Phase 1 ESA includes the following tasks: 1. Perform a reconnaissance of the subject property for significant surficial signs of chemical release, improper storage of hazardous materials, and surface indications of the presence of underground storage tanks (USTs) or water wells. 2. Provide off site research into the past land use of the subject property. 3. Review locally available aerial photographs for obvious surficial features indicative of past land use. Review available USGS topographic maps, fire insurance maps, and local telephone directories. 4. Review Federal, State and Local Agency files (available during the time frame of this project) for fuel leak and chemical release lists indicating soil and groundwater contamination cases within a ¼ mile radius to the site, as made available through the above-mentioned agency files. Based on ASTM E1527, Federal, State, and other regulatory agency guidelines, the following presumptions were in force during site reconnaissance and/or evaluation of the subject property for specific hazardous substances: • Use of asbestos in many products was banned in 1993; however, several categories of building products were not subject to the ban. Thus, existing and even new buildings may lawfully contain asbestos containing building material (ACBM). 1-2 Project No. 19-9351 • Use of lead-based paint (LBP) for residential use was prohibited in 1978 in concentrations greater than 0.06 percent lead by weight. It should be noted that the use of LBP in commercial and industrial buildings has not been prohibited. • Fluorescent light ballasts will be considered PCB-free and will not be noted in the report regardless of their date of manufacture, unless GEM is instructed to do otherwise in writing by the client. • Electrical transformers installed after 1979 must contain less than 50 parts per million of PCB (this is the requirement for the classification, “PCB non-contaminated”). GEM also conducted a "drive-by" survey of the adjoining properties to note the operations which may pose an imminent or potential environmental threat to the subject property. 1.2 EXCEPTIONS AND/OR DELETIONS There are no known exceptions or deletions. 1.3 NON-SCOPE ITEMS Evaluation of non-scope items is not required or relevant for compliance with the all appropriate inquiries (AAI) Rule or E1527. Inclusion of any non-scope item in a Phase I report is entirely within the discretion of the user based on its own risk tolerance. Non-scope items include, but not limited to, ACBM, biological agents, indoor air quality unrelated to releases of hazardous substances or petroleum products into the environment, mold, radon, LBP, and lead in drinking water. 1.4 USER RELIANCE This report was prepared for the sole use and benefit of Golcheh Group (client), and is based, in part, upon documents, writings, and information owned and possessed by our client. Neither this report, nor any of the information contained herein, shall be used or relied upon for any purpose by any person or entity other than our client. 2-1 Project No. 19-9351 2.0 SITE DESCRIPTION AND RECONNAISSANCE The subject property is a 6.23-acre vacant dirt lot with weeds and trees. 2.1 SITE FACTS Address Provided by Client: 15209 Lincoln Street, Lake Elsinore, CA 92530 Assessor’s Parcel Number: 379-111-014 Total Sq. Ft of Parcel (approximate): 271,379 (6.23-acres) Total Number of Existing Structures: None Use: vacant 2.2 SITE PHOTOGRAPHS A number of photographs were taken to document the current condition and use of the subject property. The photographs with descriptions can be found in Appendix A. 2.3 GEOLOGIC AND HYDROGEOLOGIC CONDITIONS GEM reviewed pertinent, reasonably ascertainable information on the soil types and groundwater conditions in the vicinity of the subject property. The research does not include the investigation of seismological concerns (i.e., fault lines) that may affect the area of the subject property. Although the existence of faults in an area may be of concern to property owners and residents in that area, it is not considered to be an environmental concern, and so is not usually a component of a Phase I ESA. The elevation of the subject property is approximately 1,279 feet above mean sea level. The subject property is underlain by Pleistocene to Holocene age sediments of alluviums, gravel, sand, silt, and. The subject property is in the Elsinore Valley Groundwater Basin. Groundwater is primarily used for municipal and irrigational purposes. Case closure letters for sites in the general vicinity of the subject property indicated that depth to groundwater was encountered at approximately 28 to 63 feet below ground surface (bgs). Groundwater direction in this region is estimated to flow towards Lake Elsinore which is located 0.5 miles southeast of the subject property. These sites are located approximately 0.8 miles from the subject property. It should be noted that these information is taken from reports for investigations conducted at other properties in the general vicinity and may not be representative of conditions at the subject property. It should be noted that the flow direction and depth of groundwater may be influenced by rainfall, tidal activity (shore properties), and local groundwater pumping operations. It should also be noted that shallower, unreported, perched groundwater zones may occur in the immediate site vicinity. 2.4 SITE RECONNAISSANCE A visual site reconnaissance of the subject property was conducted on July 21, 2019 to identify observable signs of environmental impairments, including on-site operations and maintenance activities which may 2-2 Project No. 19-9351 lead to possible environmental impairment. As a part of the site reconnaissance the subject property was visually inspected for obvious indications of the following: DESCRIPTION COMMENT Aboveground Storage Tanks (AST) None Back-up Power Generators (diesel, battery, natural gas) None Chemical/Hazardous Materials Storage Area None Creeks/ Canals None Debris or Debris Stockpile None Dispenser Islands, Concrete Pads, and/or Cradles (Fuel) None Dry Cleaner (drop-off, onsite) None Electrical Transformers (pole or ground) None Evidence of Soil Borings None Evidence of Soil Excavation None Fill Materials None Drains (trench drains, proximity to HazMat/ waste) None Floor Staining or Corrosion (inside) None Forklift (type) None Grease Drum None Grease Trap None Health and Safety Issues (e.g. molds, standing water) None Heating/Cooling Systems None Hydraulic Hoists/Elevator (No./Type) None Industrial Wastewater None Loading Dock (drain) None Odors None Oil Burners/Furnace None Oil-Water Separator/Clarifier None Patches (concrete, asphalt) None Petroleum Containers (No./size/type) None Pipes of Unknown Uses None Pits, Ponds, or Lagoons None Pools of Liquid None Railroad, spurs None Septic Systems None Stained Soil or Pavement None Stockpiled Soil None Storm Drains/ Catch Basins None Stressed Vegetation None Sump None Underground Storage Tanks None Unidentified/Abandoned Containers None Well, Type? None The compliance review is not intended as a comprehensive compliance audit. Rather, the compliance review is only intended to aid GEM in determining the likelihood that the subject property may have been 2-3 Project No. 19-9351 impacted by releases of hazardous substances. 2.4.1 OTHER ENVIRONMENTAL CONDITIONS There are no other environmental conditions other than those previously discussed. 2.5 VISUAL OBSERVATIONS, ADJOINING SITES During the site reconnaissance, the GEM field assessor performed a "drive-by" survey of the adjoining properties to note operations that may pose an imminent or potential environmental threat to the subject property. The area is generally occupied by residential and commercial properties. Adjoining and adjacent properties are: • Northwest: Flannery Street, Lakehouse Apartments (15195 Lincoln Street) • Northeast: Lincoln Street, Brookstone Landing multi-unit commercial building (31733 Riverside Drive) • Southeast: Riverside Drive, Launch Pointe (32040 Riverside Drive) • Southwest: Lakeview Apartments (32209 Riverside Drive) 3-1 Project No. 19-9351 3.0 REVIEW OF HISTORICAL INFORMATION AND REGULATORY AGENCY RECORDS 3.1 ARCHIVED AGENCY RECORDS SEARCH GEM submitted requests to review or obtain records from Agencies who have jurisdiction over the subject property. Records, if available, may either provide information about the environmental conditions on the subject property, or establish that no environmentally relevant records are on file for the subject property. A list of regulatory references/sources is provided in Section 5.0. Copies of records are included in Appendix B. 3.1.1 STATE WATER QUALITY CONTROL BOARD The State Water Quality Control Board website does not list the subject property with ongoing site assessment or remediation. 3.1.2 DEPARTMENT OF TOXIC SUBSTANCES CONTROL The Department of Toxic Substances Control website does not list the subject property with ongoing site assessment or remediation. 3.1.3 DEPARTMENT OF CONSERVATION, DIVISION OF OIL, GAS, & GEOTHERMAL RESOURCES The Department of Conservation, Division of Oil, Gas & Geothermal Resources website does not identify the presence of oil or gas wells on the subject property. The closest listed inactive well is approximately 2 miles northeast of the subject property. 3.1.4 DEPARTMENT OF TRANSPORTATION, NATIONAL PIPELINE MAPPING SYSTEM The Department of Transportation, National Pipeline Mapping System website does not identify the presence of hazardous materials pipelines on the subject and adjacent properties. 3.1.5 SOUTH COAST AIR QUALITY MANAGEMENT DISTRICT The South Coast Air Quality Management District does not have permits on file for the subject property. 3.1.6 REGIONAL WATER QUALITY CONTROL BOARD, SANTA ANA REGION The Santa Ana Regional Water Quality Control Board (SARWQCB) does not have records on file for the subject property. 3.1.7 ASSESSOR’S OFFICE, RIVERSIDE COUNTY The subject property is an undeveloped 6.23-acre lot. The Assessor’s Parcel Number is 379-111-014. 3-2 Project No. 19-9351 3.1.8 BUILDING DEPARTMERNT, RIVERSIDE COUNTY The Riverside County Building Department does not have records on file for the subject property. 3.1.9 FIRE DEPARTMENT, RIVERSIDE COUNTY The Riverside County Fire Department does not have the capabilities to provide requested environmental records. Relevant documents are provided by the Riverside County Environmental Resources Management Division. 3.1.10 ENVIRONMENTAL REOSURCES MANAGEMENT DIVISION, RIVERSIDE COUNTY The Riverside County Environmental Resources Management Division does not have records on file for the subject property. 3.1.11 DEPARTMENT OF PUBLIC WORKS, RIVERSIDE COUNTY The Riverside County Department of Public Works does not have records on file for the subject property. 3.1.12 FIRE DEPARTMENT, CITY OF LAKE ELSINORE The City of Lake Elsinore Fire Department was associated with a letter from 1987 to J. Grosvenor referencing standing walls on the subject property after a controlled burn. Debris removal including all foundations was noted to be completed. 3.1.13 BUILDING DEPARTMENT, CITY OF LAKE ELSINORE Historical building permits on file for the subject property are dated from 1979 through 2016. A permit from 1979 was associated with public sewer connection to a house. The tenant/owner name was blurred/illegible. A permit from 1987 was associated with “old house”. The remainder of the permit was blurred and illegible. A closed complaint from 2016 was associated with junk, trash, and debris on the vacant subject property. 3.2 REVIEW OF REGULATORY AGENCY DATABASES GEM has also reviewed a vendor-supplied, computer-generated federal, state, and regional one-mile regulatory database search in an effort to determine whether the subject property is listed on an agency environmental database and to identify possible regulatory-listed sites of concern within a one-mile radius of the subject property. In general, these documents list known or suspected hazardous-waste generators, release sites, landfills, unauthorized disposal sites, sites with registered underground storage tanks, and sites currently under investigation for known or suspected environmental violations or releases. The 2012 Leaking Underground Fuel Tank Guidance Manual published by the California State Water Resource Control Board references numerous plume studies. A 2004 study at 500 UST sites in Los Angeles showed 90 percent of the benzene plumes were less than 350 feet long and 90 percent of the methyl tert- 3-3 Project No. 19-9351 butyl ether (MTBE) plumes were less than 545 feet long (at 5 mi crograms/liter [μg/L]). Based on this, GEM assesses the potential environmental impact of petroleum hydrocarbon sites within 0.125 miles (660 feet) of the subject property. GEM assesses the potential environmental impact of a dry cleaner (PCE sites) with active investigation and remediation on the subject property. Since plumes from dry cleaners are generally longer than petroleum hydrocarbon plumes, GEM assesses the potential environmental impact of PCE sites within 0.25 miles (1,320 feet) of the subject property. The Federal and State listings are summarized in the table below: Government Records Description ASTM Search Distance (miles) Total Listing Federal National Priority List (NPL) U.S. Environmental Protection Agency’s (EPA) list of national priorities among known or threatened releases of hazardous substances, pollutants, or contaminants throughout the U.S. and its territories.

These databases identified the following listings within 0.25 miles of the subject property: Source List Description Search Distance (miles) Total Listing DCF2, DryCleaners, Cleaners drycleaners reported by the DTSC 0.25 1 Historical listings listings from historical databases that are no longer updated/used. Listings may have been closed or transferred to active databases 0.0625- 0.25 1 Historical Service Station records dating back to the 1800's that have shown up in historic resources and based on their classification, may have used hazardous materials or petroleum products. 0.25 1 Spill-SSO database contains private lateral sewage discharges from RWQCB 0.25 1 The subject property is not listed in the regulatory databases reviewed. The following adjoining and immediately adjacent properties are listed in the regulatory databases reviewed: 32040 Riverside Drive is located south across Riverside Drive, (RV Resort Rehabilitation Project, Campground Boat Launch Facility Improvements, & Lake Elsinore Recreation Area): • Identified stormwater construction site. • Historical service station in 2002. • This site is located in between the subject property and Lake Elsinore. This site is located down- gradient from the subject property. Based on the available information, the potential for presence of environmental impact on the subject property appears low at this time. The Cleaners listing is located 0.15 miles from the subject property. There are no listed violations or investigations at this time. There are no listings which appear to present potential environmental impact on the subject property at this time. A copy of the complete database search document and a detailed description of the databases that were searched are included in Appendix C. 3.3 REVIEW OF HISTORICAL AERIAL PHOTOGRAPHS GEM reviewed readily available and reasonably ascertainable aerial photographs of the area of the subject property. Each aerial photograph was reviewed for the subject property and, where applicable, adjacent property use. 3-6 Project No. 19-9351 Aerial photographs for the years of 1938, 1967, 1978, 1980, 1994, 2005, 2009, 2010, 2012, 2014, 2015, 2016, 2017, and 2018 were reviewed. The 1938 aerial photograph shows what appears to be multiple structures in the northeastern corner. The remainder of the subject property was vacant land. The immediate vicinity, including the subject property, is agricultural. The 1967 through 1980 aerial photographs still showed structures along the northeast corner. The remainder of the subject property was part of an orchard. The orchard appears to have been abandoned and allowed to die. The general area was mostly undeveloped with few residential developments. The 1994 through 2018 aerial photographs showed the subject property as undeveloped vacant land. The general area was developed with mostly residential and commercial structures. 3.4 REVIEW OF HISTORICAL USGS TOPOGRAPHIC MAPS GEM reviewed readily available and reasonably ascertainable USGS topographic maps of the area of the subject property. USGS topographic maps was reviewed for the subject property and, where applicable, adjacent property use. USGS topographic maps for the years of 1955, 1957, 1967, 1975, 1985, 1988, 2000, 2001, 2012, and 2015 were reviewed. The 1955 through 1967 USGS topographic maps showed the general area as orchards with road development. The 1975 through 2015 USGS topographic maps showed the general area developed with buildings and roads. Orchards were depicted in the vicinity through 2001. 3.5 REVIEW OF HISTORICAL FIRE INSURANCE MAPS Fire insurance maps are the most detailed historical records of the urban landscape. From 1790 to 1961, nearly every U.S. town and city with populations of 2,000 or more had been surveyed. Shown on these maps, sometimes in great detail, is virtually every building, man-made structure, and business standing at the time the survey was made. A search of multiple national collections and indexes of historical fire insurance maps was conducted for the above referenced site address. The review of collections and indexes has determined that no historical fire insurance maps are available within these collections and indexes for the referenced site; therefore they are not available and are considered not "reasonably ascertainable" according to ASTM standards. A copy of the report is included in Appendix C. 3.6 REVIEW OF HISTORICAL CITY DIRECTORIES One of the least known, yet most complete and comprehensive historical sources are historical city or street 3-7 Project No. 19-9351 directories. GEM reviews historical city or street directories (also known as criss-cross or reverse indexed directories) for information on the past occupants of and activities on the subject property and adjoining properties. If they were reasonably ascertainable, they were reviewed to determine current or past occupants of the subject property. Historical city or street directories were available for 1985, 1990, 1995, 2000, 2004-2005, and 2007-2008. The listings are provided below: 15209 Lincoln Street (subject property) • 1985 – 2008 – Address Not Listed 32040 Riverside Avenue (adjacent south property) • 1985 – California State Park & Recreation Bus Service Campground and Ranger, Lake Elsinore State Park, Watkins Scott • 1990 – California State Park & Recreation Bus Service Campground and Ranger, Lake Elsinore State Park, Hogue Jas and Linda, Jones Linda K • 1995 – California State Park & Recreation Campground and Ranger, Lake Elsinore State Park, Dearagon Alejandra • 2000 – Jones Linda, Lake Elsinore Parks & Recreation Campground • 2004-2005 – Pyramid Enterprises Inc • 2007-2008 – Lake Elsinore City Campgrounds, Pyramid Enterprises Inc A copy of the report is included in Appendix C. 3.7 PRIOR OR CURRENT AGRICULTURAL LAND USE The subject and adjoining properties were used for agriculture from at least 1938. Agrichemicals are primarily sprayed on the foliage or ground surface. Their potential for subsurface migration to a depth greater than 2 feet below ground surface is not likely as they will have primarily degraded. Also, residual concentrations, if any, would naturally attenuate over time. If the subject property is redeveloped for residential use, then soil sampling may be required to determine the presence of pesticides. 3.8 QUESTIONNAIRE AND/OR INTERVIEW An environmental questionnaire was not completed/submitted by the client for the completion of this report. 3.9 ADDITIONAL ENVIRONMENTAL DOCUMENTS No additional environmental document was provided for review. 3.10 HISTORICAL SITE USE The chronological historical site use summary below is based on reviewed aerial photographs, maps, 3-8 Project No. 19-9351 regulatory agency files, interviews, and additional environmental documents: • 1938 – 1987 – residential/orchards • 1987 – current – undeveloped vacant lot 3.11 TIER 1 VAPOR ENCROACHMENT SCREENING Tier 1 vapor encroachment screening (VES) was conducted in general accordance with ASTM E2600-15, “Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions.” The goal of conducting a VES, is to identify a vapor encroachment condition (VEC), which is the presence or likely presence of volatile and toxic vapors in the vadose zone of the subject property caused by the release of vapors from contaminated soil and/or groundwater either on or near the subject property. The default area of concern is 1/10th mile (0.1 mile = 528 feet) for petroleum hydrocarbon chemicals of concern and 1/3rd mile (0.33 mile = 1,760 feet) for other non-petroleum hydrocarbon chemicals of concern around the subject property. The area of concern may be expanded or reduced based on chemicals of concern, soil characteristics, depth/direction of groundwater, surficial feature and other pertinent information to determine whether a VEC exists or a VEC does not exist. Vapor intrusion is the general term given to migration of hazardous vapors from any subsurface vapor source, such as contaminated soil or groundwater, through the soil and into an overlying building or structure. These vapors can enter buildings through cracks in basements and foundations, as well as through conduits and other openings in the building envelope. Vapors can also enter structures that are not intended for human occupancy (e.g., sewers, drain lines, access vaults, storage sheds, pump houses) through cracks and other openings. All types of buildings, regardless of foundation type (e.g., basement, crawl space, slab-on-grade), have openings that render them potentially vulnerable to vapor intrusion. Buildings subject to vapor intrusion include, but are not limited to, residential buildings (e.g., detached single-family homes, trailer or ‘mobile’ homes, multi-unit apartments and condominiums), commercial workplaces (e.g., office buildings, retail establishments), educational and recreational buildings (e.g., schools and gyms), and industrial facilities (e.g., manufacturing plants). The U.S. Environmental Protection Agency’s Technical Guide for Assessing and Mitigating the Vapor Intrusion Pathway from Subsurface Vapor Sources to Indoor Air (OSWER Publication 9200.2-154, June 2015) recommends that 100 feet laterally and vertically is a reasonable initial criterion when considering vapor migration fundamentals. The buffer zone of approximately 100 feet has generally been used in determining which buildings to include in vapor intrusion investigations when significant surface covers are not present, under the assumption that preferential vapor migration routes are absent. Use of the 100- foot buffer zone would be inappropriate for landfills, commercial/industrial releases within an enclosed space, or leaking vapors from natural gas lines. Based on available information, a VEC does not exist at the subject property. 3-9 Project No. 19-9351 3.12 REVIEW OF PRELIMINARY TITLE REPORT A preliminary title report was not available for review. 3.13 REVIEW OF APPRAISAL REPORT An appraisal report was not available for review. 3.14 IDENTIFICATION OF HISTORICAL DATA GAPS Data gaps may result from the lack of or inability to obtain information required by ASTM E1527 despite good faith efforts by the environmental professional to gather such information. Data gaps are only significant if “other information and/or professional experience raise reasonable concerns involving the data gap.” Data gaps may include, but are not limited to, site reconnaissance, interviews, review of standard historical sources, etc. ASTM E1527 requires that all obvious uses of the property shall be identified from the present, back to the property’s first developed use, or back to 1940, whichever is earlier. During the course of this Phase I ESA, GEM did not identify significant data gaps within the reviewed historic documents for the subject property that could affect the conclusions of this report. 4-1 Project No. 19-9351 4.0 FINDINGS AND RECOMMENDATIONS 4.1 FINDINGS The subject property is a 6.23-acre vacant dirt lot with weeds and trees. Historical sources show the subject property developed with multiple structures along the northeast corner from at least 1938 through 1987 when it appears the structures were demolished. The remainder of the subject property was part of an orchard. The orchard appears to have been abandoned and allowed to die prior to the 1980s. The subject property appears to have been undeveloped since at least 1987. The subject property is not listed in the regulatory databases reviewed. There were no records from various regulatory agencies that identify the potential for adverse environmental impact from the subject and adjoining properties. There are no listed offsite listings with the potential for adverse environmental impact on the subject property. 4.1.1 RECOGNIZED ENVIRONMENTAL CONDITION A REC refers to the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. There are no RECs identified at the subject property at this time. 4.1.2 HISTORICAL REC Historical REC refers to a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls). There are no historical RECs identified at the subject property at this time. 4.1.3 CONTROLLED REC Controlled REC is a REC resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority (for example, as evidenced by the issuance of a no further action letter or equivalent, or meeting risk-based criteria established by regulatory authority), with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls). There are no controlled RECs identified at the subject property at this time. 4-2 Project No. 19-9351 4.1.4 DE MINIMIS CONDITIONS A de minimis condition generally does not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. Conditions determined to be de minimis conditions are not RECs nor controlled RECs. There are no de minimis conditions at the subject property at this time. 4.1.5 BUSINESS ENVIRONMENTAL RISK BER is a risk which can have a material environmental or environmentally driven impact on the business associated with the current or planned use of commercial real estate, and is not an issue required to be investigated under this practice. A BER may include one or more of the non-scope issues contained in subsection 1.3. There are no BERs associated with the subject property at this time. 4.2 RECOMMENDATIONS Given the findings and conclusions of this Phase I ESA, GEM recommends no further investigation at this time. However, if the subject property is redeveloped for residential use, then soil sampling may be required to determine the presence of pesticides from former orchard use. 5-1 Project No. 19-9351 5.0 REGULATORY AGENCIES Federal and/or State Agencies State Water Quality Control Board http://geotracker.waterboards.ca.gov/ Santa Ana Regional Water Quality Control Board (SARWQCB) FileReview8@waterboards.ca.gov Department of Toxic Substances Control http://www.envirostor.dtsc.ca.gov/ Department of Conservation, Division of Oil, Gas, & Geothermal Resources https://maps.conservation.ca.gov/doggr/wellfinder/#close Department of Transportation, National Pipeline Mapping System https://pvnpms.phmsa.dot.gov/PublicViewer/ South Coast Air Quality Management District http://www.aqmd.gov/nav/online-services/public-records County Agencies Assessor’s Office http://pic.asrclkrec.com/ Environmental Health http://www.rivcoeh.org Fire Department RRURecords@fire.ca.gov Building Department http://rctlma.org/building/Records-Request Department of Public Works http://rctlma.org/ce/PublicRecordsRequest City Agencies Fire Department http://www.lake-elsinore.org/Home/Components/Form Building Department http://www.lake-elsinore.org/Home/Components/Form Environmental Records Search City Directories https://www.reccheck.com/store/default.asp Fire Insurance Maps Regulatory Agency Databases Topographic Maps https://www.historicaerials.com/ and Google Earth Aerial Photographs 6-1 Project No. 19-9351 6.0 LIMITATIONS To achieve the study objectives stated in this report, we were required to base GEM conclusions and recommendations on the best information available during the period the Phase I ESA was conducted and within the limits prescribed by GEM client in the contract/authorization agreement and standard terms and conditions. GEM’s professional services were performed using that degree of care and skill ordinarily exercised by environmental consultants practicing in this or similar fields. Resumes are included in Appendix D. The findings were mainly based upon examination of historic records, maps, aerial photographs, and governmental agencies lists. The hazardous waste site lists re presented in this report represent only a search of the specific government records as listed above. It should be noted that governmental agencies often do not list all sites with environmental contamination; the lists could be inaccurate and/or incomplete. Recommendations are based on the historic land use of the subject property, as well as features noted during the site reconnaissance and examined records. The absence of potential gross contamination sources, historic or present, does not necessarily imply that the subject property is free of any contamination. This report only represents a "due diligence" effort as to the integrity of the subject property. No warranty or guarantee, expressed or implied, is made as to the professional conclusions or recommendations contained in this report. The limitations contained within this report supersede all other contracts or scopes of work, implied or otherwise, except those stated or acknowledged herewith. This report is not a legal opinion. It does not necessarily comply with requirements defined in any environmental law such as the "innocent landowner defense" or "due diligence inquiry." Only legal counsel retained by the client is competent to determine the legal implications of any information, conclusions, or recommendations in this report. The compliance status is not intended for use as a guide to compliance for the present owner.

A clean and healthy watershed is important to all of us. Trash, debris, chemicals and other contaminants from business activities often make their way into the Riverside County storm drain system. This pollutes our drinking water and contaminates waterways, making them unsafe for people and wildlife. Did you know? There is a difference between storm drains and sewers. Storm drains capture rainwater and flow directly to our rivers, lakes and streams – untreated. Sewers capture and collect water from sinks, toilets and floor drains, and then it is processed and treated before it is released into the environment. Watershed Protection Restaurants Mobile Food Trucks Grocery Stores Bakeries Delicatessens Questions? If you have questions about Best Management Practices, or if you have questions about illicit dumpin g and stormwater pollution visit the Pollution Prevention website : rcwatershed.org. For more information on requirements for all retail food facilities go to Riverside County Environmental Health’s website: rivcoeh.org Riverside County Watershed Protection Program is managed by Riverside County Flood Control & Water Conservation District in partnership with 27 Cities, the County of Riverside and the Coachella Valley Water District. OUR MISSION “To protect, preserve and enhance the quality of Riverside County watersheds by fostering a community-wide commitment to clean water.” Best Kitchen Practices Dumpster Areas Keep dumpster lids closed and the areas around them clean. Do not fill with liquid waste or hose them out. Call your trash hauler to replace any dumpsters that are damaged or leaking. Mobile Food Trucks The potential for generating stormwater pollution as part of a mobile food business requires special attention. Cleaning activities are required to be conducted at an approved fixed location with a connection to a sanitary sewer. For more information contact Riverside County Environmental Health at (888) 722-4234. Do not discharge wash water into storm drains. Clean on a properly equipped wash pad and drain wastewater to a sanitary sewer system. Cleaning & Maintenance Clean equipment, floor mats, filters and garbage cans in a mop sink, wash rack or floor drain connected to a sanitary sewer. Sweep outside areas and put the debris in trash containers DO NOT hose down or sweep into the parking lot or street. Outside eating areas and sidewalks may not be hosed down or pressure washed UNLESS the following standards are met: Use dry cleanup methods prior to any pressure washing – absorbing with kitty litter, sweeping, vacuuming, scraping off dried debris. Wash waters must be captured for proper disposal: collected waters should be discharged to a sanitary drain. DO NOT use any chemicals or detergents. DO NOT wash or pour water in a parking lot, alley, sidewalk or street. Food Waste Disposal Scrape food waste off of plates, pots and food prep areas and dispose of in the trash. Food scraps often contain grease, which can clog sewer pipes and result in costly sewer backups and overflows. Never put food waste down the drain. Recycle Oil & Grease Never put oil or grease down the drain. Contain grease and oil by using covered grease storage containers or installing a grease interceptor. Never overfill your grease storage container or transport it without a cover. Grease control devices must be emptied and cleaned by permitted companies and according to manufacturer’s specifications. Keep maintenance records on site. For a list of oil/grease recycling companies, contact CalRecycle www.calrecycle.ca.gov or contact your local sanitation district. Managing Spills Clean food spills in loading and trash areas by using absorbent materials and sweeping then mopping. Discharge mop water into the sewer through a grease interceptor.

Riverside County - Low Impact Development BMP Design Handbook rev. 2/2012 Page 1 3.5 Bioretention Facility Description Bioretention Facilities are shallow, vegetated basins underlain by an engineered soil media. Healthy plant and biological activity in the root zone maintain and renew the macro‐pore space in the soil and maximize plant uptake of pollutants and runoff. This keeps the Best Management Practice (BMP) from becoming clogged and allows more of the soil column to function as both a sponge (retaining water) and a highly effective and self‐maintaining biofilter. In most cases, the bottom of a Bioretention Facility is unlined, which also provides an opportunity for infiltration to the extent the underlying onsite soil can accommodate. When the infiltration rate of the underlying soil is exceeded, fully biotreated flows are discharged via underdrains. Bioretention Facilities therefore will inherently achieve the maximum feasible level of infiltration and evapotranspiration and achieve the minimum feasible (but highly biotreated) discharge to the storm drain system. Siting Considerations These facilities work best when they are designed in a relatively level area. Unlike other BMPs, Bioretention Facilities can be used in smaller landscaped spaces on the site, such as: Parking islands Medians Site entrances Landscaped areas on the site (such as may otherwise be required through minimum landscaping ordinances), can often be designed as Bioretention Facilities. This can be accomplished by: Depressing landscaped areas below adjacent impervious surfaces, rather than elevating those areas Grading the site to direct runoff from those impervious surfaces into the Bioretention Facility, rather than away from the landscaping Sizing and designing the depressed landscaped area as a Bioretention Facility as described in this Fact Sheet Type of BMP LID – Bioretention Treatment Mechanisms Infiltration, Evapotranspiration, Evaporation, Biofiltration Maximum Drainage Area This BMP is intended to be integrated into a project’s landscaped area in a distributed manner. Typically, contributing drainage areas to Bioretention Facilities range from less than 1 acre to a maximum of around 10 acres. Other Names Rain Garden, Bioretention Cell, Bioretention Basin, Biofiltration Basin, Landscaped Filter Basin, Porous Landscape Detention Riverside County - Low Impact Development BMP Design Handbook rev. 2/2012 Page 2 Bioretention Facilities should however not be used downstream of areas where large amounts of sediment can clog the system. Placing a Bioretention Facility at the toe of a steep slope should also be avoided due to the potential for clogging the engineered soil media with erosion from the slope, as well as the potential for damaging the vegetation. Design and Sizing Criteria The recommended cross section necessary for a Bioretention Facility includes: Vegetated area 18' minimum depth of engineered soil media 12' minimum gravel layer depth with 6' perforated pipes (added flow control features such as orifice plates may be required to mitigate for HCOC conditions) While the 18‐inch minimum engineered soil media depth can be used in some cases, it is recommended to use 24 inches or a preferred 36 inches to provide an adequate root zone for the chosen plant palate. Such a design also provides for improved removal effectiveness for nutrients. The recommended ponding depth inside of a Bioretention Facility is 6 inches; measured from the flat bottom surface to the top of the water surface as shown in Figure 1. Because this BMP is filled with an engineered soil media, pore space in the soil and gravel layer is assumed to provide storage volume. However, several considerations must be noted: Surcharge storage above the soil surface (6 inches) is important to assure that design flows do not bypass the BMP when runoff exceeds the soil’s absorption rate. In cases where the Bioretention Facility contains engineered soil media deeper than 36 inches, the pore space within the engineered soil media can only be counted to the 36‐ inch depth. A maximum of 30 percent pore space can be used for the soil media whereas a maximum of 40 percent pore space can be use for the gravel layer. Figure 1: Standard Layout for a Bioretention Facility BIORETENTION FACILITY BMP FACT SHEET Riverside County - Low Impact Development BMP Design Handbook rev. 2/2012 Page 3 Engineered Soil Media Requirements The engineered soil media shall be comprised of 85 percent mineral component and 15 percent organic component, by volume, drum mixed prior to placement. The mineral component shall be a Class A sandy loam topsoil that meets the range specified in Table 1 below. The organic component shall be nitrogen stabilized compost1, such that nitrogen does not leach from the media. Table 1: Mineral Component Range Requirements Percent Range Component 70‐80 Sand 15‐20 Silt 5‐10 Clay The trip ticket, or certificate of compliance, shall be made available to the inspector to prove the engineered mix meets this specification. Vegetation Requirements Vegetative cover is important to minimize erosion and ensure that treatment occurs in the Bioretention Facility. The area should be designed for at least 70 percent mature coverage throughout the Bioretention Facility. To prevent the BMP from being used as walkways, Bioretention Facilities shall be planted with a combination of small trees, densely planted shrubs, and natural grasses. Grasses shall be native or ornamental; preferably ones that do not need to be mowed. The application of fertilizers and pesticides should be minimal. To maintain oxygen levels for the vegetation and promote biodegradation, it is important that vegetation not be completely submerged for any extended period of time. Therefore, a maximum of 6 inches of ponded water shall be used in the design to ensure that plants within the Bioretention Facility remain healthy. A 2 to 3‐inch layer of standard shredded aged hardwood mulch shall be placed as the top layer inside the Bioretention Facility. The 6‐inch ponding depth shown in Figure 1 above shall be measured from the top surface of the 2 to 3‐inch mulch layer. Curb Cuts To allow water to flow into the Bioretention Facility, 1‐foot‐wide (minimum) curb cuts should be placed approximately every 10 feet around the perimeter of the Bioretention Facility. Figure 2 shows a curb cut in a Bioretention Facility. Curb cut flow lines must be at or above the VBMP water surface level. 1 For more information on compost, visit the US Composting Council website at: http://compostingcouncil.org/ BIORETENTION FACILITY BMP FACT SHEET Riverside County - Low Impact Development BMP Design Handbook rev. 2/2012 Page 4 Figure 2: Curb Cut located in a Bioretention Facility To reduce erosion, a gravel pad shall be placed at each inlet point to the Bioretention Facility. The gravel should be 1‐ to 1.5‐inch diameter in size. The gravel should overlap the curb cut opening a minimum of 6 inches. The gravel pad inside the Bioretention Facility should be flush with the finished surface at the curb cut and extend to the bottom of the slope. In addition, place an apron of stone or concrete, a foot square or larger, inside each inlet to prevent vegetation from growing up and blocking the inlet. See Figure 3. Terracing the Landscaped Filter Basin It is recommended that Bioretention Facilities be level. In the event the facility site slopes and lacks proper design, water would fill the lowest point of the BMP and then discharge from the basin without being treated. To ensure that the water will be held within the Bioretention Facility on sloped sites, the BMP must be terraced with nonporous check dams to provide the required storage and treatment capacity. The terraced version of this BMP shall be used on non‐flat sites with no more than a 3 percent slope. The surcharge depth cannot exceed 0.5 feet, and side slopes shall not exceed 4:1. Table 2 below shows the spacing of the check dams, and slopes shall be rounded up (i.e., 2.5 percent slope shall use 10' spacing for check dams). Table 2: Check Dam Spacing 6” Check Dam Spacing Slope Spacing 1% 25' 2% 15' 3% 10' Figure 3: Apron located in a Bioretention Facility BIORETENTION FACILITY BMP FACT SHEET Riverside County - Low Impact Development BMP Design Handbook rev. 2/2012 Page 5 Roof Runoff Roof downspouts may be directed towards Bioretention Facilities. However, the downspouts must discharge onto a concrete splash block to protect the Bioretention Facility from erosion. Retaining Walls It is recommended that Retaining Wall Type 1A, per Caltrans Standard B3‐3 or equivalent, be constructed around the entire perimeter of the Bioretention Facility. This practice will protect the sides of the Bioretention Facility from collapsing during construction and maintenance or from high service loads adjacent to the BMP. Where such service loads would not exist adjacent to the BMP, an engineered alternative may be used if signed by a licensed civil engineer. Side Slope Requirements Bioretention Facilities Requiring Side Slopes The design should assure that the Bioretention Facility does not present a tripping hazard. Bioretention Facilities proposed near pedestrian areas, such as areas parallel to parking spaces or along a walkway, must have a gentle slope to the bottom of the facility. Side slopes inside of a Bioretention Facility shall be 4:1. A typical cross section for the Bioretention Facility is shown in Figure 1. Bioretention Facilities Not Requiring Side Slopes Where cars park perpendicular to the Bioretention Facility, side slopes are not required. A 6‐ inch maximum drop may be used, and the Bioretention Facility must be planted with trees and shrubs to prevent pedestrian access. In this case, a curb is not placed around the Bioretention Facility, but wheel stops shall be used to prevent vehicles from entering the Bioretention Facility, as shown in Figure 4. Figure 4: Bioretention Facility Layout without Side Slopes BIORETENTION FACILITY BMP FACT SHEET Riverside County - Low Impact Development BMP Design Handbook rev. 2/2012 Page 6 Planter Boxes Bioretention Facilities can also be placed above ground as planter boxes. Planter boxes must have a minimum width of 2 feet, a maximum surcharge depth of 6 inches, and no side slopes are necessary. Planter boxes must be constructed so as to ensure that the top surface of the engineered soil media will remain level. This option may be constructed of concrete, brick, stone or other stable materials that will not warp or bend. Chemically treated wood or galvanized steel, which has the ability to contaminate stormwater, should not be used. Planter boxes must be lined with an impermeable liner on all sides, including the bottom. Due to the impermeable liner, the inside bottom of the planter box shall be designed and constructed with a cross fall, directing treated flows within the subdrain layer toward the point where subdrain exits the planter box, and subdrains shall be oriented with drain holes oriented down. These provisions will help avoid excessive stagnant water within the gravel underdrain layer. Similar to the in‐ground Bioretention Facility versions, this BMP benefits from healthy plants and biological activity in the root zone. Planter boxes should be planted with appropriately selected vegetation. Figure 5: Planter Box Source: LA Team Effort Overflow An overflow route is needed in the Bioretention Facility design to bypass stored runoff from storm events larger than VBMP or in the event of facility or subdrain clogging. Overflow systems must connect to an acceptable discharge point, such as a downstream conveyance system as shown in Figure 1 and Figure 4. The inlet to the overflow structure shall be elevated inside the Bioretention Facility to be flush with the ponding surface for the design capture volume (VBMP) as shown in Figure 4. This will allow the design capture volume to be fully treated by the Bioretention Facility, and for larger events to safely be conveyed to downstream systems. The overflow inlet shall not be located in the entrance of a Bioretention Facility, as shown in Figure 6. BIORETENTION FACILITY BMP FACT SHEET Riverside County - Low Impact Development BMP Design Handbook rev. 2/2012 Page 7 Underdrain Gravel and Pipes An underdrain gravel layer and pipes shall be provided in accordance with Appendix B – Underdrains. Figure 6: Incorrect Placement of an Overflow Inlet. Inspection and Maintenance Schedule The Bioretention Facility area shall be inspected for erosion, dead vegetation, soggy soils, or standing water. The use of fertilizers and pesticides on the plants inside the Bioretention Facility should be minimized. Schedule Activity Ongoing Keep adjacent landscape areas maintained. Remove clippings from landscape maintenance activities. Remove trash and debris Replace damaged grass and/or plants Replace surface mulch layer as needed to maintain a 2‐3 inch soil cover. After storm events Inspect areas for ponding Annually Inspect/clean inlets and outlets Site Design & Landscape Planning SD-10 January 2003 California Stormwater BMP Handbook 1 of 4 New Development and Redevelopment www.cabmphandbooks.com Description Each project site possesses unique topographic, hydrologic, and vegetative features, some of which are more suitable for development than others. Integrating and incorporating appropriate landscape planning methodologies into the project design is the most effective action that can be done to minimize surface and groundwater contamination from stormwater. Approach Landscape planning should couple consideration of land suitability for urban uses with consideration of community goals and projected growth. Project plan designs should conserve natural areas to the extent possible, maximize natural water storage and infiltration opportunities, and protect slopes and channels. Suitable Applications Appropriate applications include residential, commercial and industrial areas planned for development or redevelopment. Design Considerations Design requirements for site design and landscapes planning should conform to applicable standards and specifications of agencies with jurisdiction and be consistent with applicable General Plan and Local Area Plan policies. Design Objectives ; Maximize Infiltration ; Provide Retention ; Slow Runoff ; Minimize Impervious Land Coverage Prohibit Dumping of Improper Materials Contain Pollutants Collect and Convey SD-10 Site Design & Landscape Planning 2 of 4 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Designing New Installations Begin the development of a plan for the landscape unit with attention to the following general principles: Formulate the plan on the basis of clearly articulated community goals. Carefully identify conflicts and choices between retaining and protecting desired resources and community growth. Map and assess land suitability for urban uses. Include the following landscape features in the assessment: wooded land, open unwooded land, steep slopes, erosion-prone soils, foundation suitability, soil suitability for waste disposal, aquifers, aquifer recharge areas, wetlands, floodplains, surface waters, agricultural lands, and various categories of urban land use. When appropriate, the assessment can highlight outstanding local or regional resources that the community determines should be protected (e.g., a scenic area, recreational area, threatened species habitat, farmland, fish run). Mapping and assessment should recognize not only these resources but also additional areas needed for their sustenance. Project plan designs should conserve natural areas to the extent possible, maximize natural water storage and infiltration opportunities, and protect slopes and channels. Conserve Natural Areas during Landscape Planning If applicable, the following items are required and must be implemented in the site layout during the subdivision design and approval process, consistent with applicable General Plan and Local Area Plan policies: Cluster development on least-sensitive portions of a site while leaving the remaining land in a natural undisturbed condition. Limit clearing and grading of native vegetation at a site to the minimum amount needed to build lots, allow access, and provide fire protection. Maximize trees and other vegetation at each site by planting additional vegetation, clustering tree areas, and promoting the use of native and/or drought tolerant plants. Promote natural vegetation by using parking lot islands and other landscaped areas. Preserve riparian areas and wetlands. Maximize Natural Water Storage and Infiltration Opportunities Within the Landscape Unit Promote the conservation of forest cover. Building on land that is already deforested affects basin hydrology to a lesser extent than converting forested land. Loss of forest cover reduces interception storage, detention in the organic forest floor layer, and water losses by evapotranspiration, resulting in large peak runoff increases and either their negative effects or the expense of countering them with structural solutions. Maintain natural storage reservoirs and drainage corridors, including depressions, areas of permeable soils, swales, and intermittent streams. Develop and implement policies and Site Design & Landscape Planning SD-10 January 2003 California Stormwater BMP Handbook 3 of 4 New Development and Redevelopment www.cabmphandbooks.com regulations to discourage the clearing, filling, and channelization of these features. Utilize them in drainage networks in preference to pipes, culverts, and engineered ditches. Evaluating infiltration opportunities by referring to the stormwater management manual for the jurisdiction and pay particular attention to the selection criteria for avoiding groundwater contamination, poor soils, and hydrogeological conditions that cause these facilities to fail. If necessary, locate developments with large amounts of impervious surfaces or a potential to produce relatively contaminated runoff away from groundwater recharge areas. Protection of Slopes and Channels during Landscape Design Convey runoff safely from the tops of slopes. Avoid disturbing steep or unstable slopes. Avoid disturbing natural channels. Stabilize disturbed slopes as quickly as possible. Vegetate slopes with native or drought tolerant vegetation. Control and treat flows in landscaping and/or other controls prior to reaching existing natural drainage systems. Stabilize temporary and permanent channel crossings as quickly as possible, and ensure that increases in run-off velocity and frequency caused by the project do not erode the channel. Install energy dissipaters, such as riprap, at the outlets of new storm drains, culverts, conduits, or channels that enter unlined channels in accordance with applicable specifications to minimize erosion. Energy dissipaters shall be installed in such a way as to minimize impacts to receiving waters. Line on-site conveyance channels where appropriate, to reduce erosion caused by increased flow velocity due to increases in tributary impervious area. The first choice for linings should be grass or some other vegetative surface, since these materials not only reduce runoff velocities, but also provide water quality benefits from filtration and infiltration. If velocities in the channel are high enough to erode grass or other vegetative linings, riprap, concrete, soil cement, or geo-grid stabilization are other alternatives. Consider other design principles that are comparable and equally effective. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) define “redevelopment” in terms of amounts of additional impervious area, increases in gross floor area and/or exterior construction, and land disturbing activities with structural or impervious surfaces. The definition of “ redevelopment” must be consulted to determine whether or not the requirements for new development apply to areas intended for redevelopment. If the definition applies, the steps outlined under “designing new installations” above should be followed. SD-10 Site Design & Landscape Planning 4 of 4 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Redevelopment may present significant opportunity to add features which had not previously been implemented. Examples include incorporation of depressions, areas of permeable soils, and swales in newly redeveloped areas. While some site constraints may exist due to the status of already existing infrastructure, opportunities should not be missed to maximize infiltration, slow runoff, reduce impervious areas, disconnect directly connected impervious areas.

Roof Runoff Controls SD-11 January 2003 California Stormwater BMP Handbook 1 of 3 New Development and Redevelopment www.cabmphandbook.com Description Various roof runoff controls are available to address stormwater that drains off rooftops. The objective is to reduce the total volume and rate of runoff from individual lots, and retain the pollutants on site that may be picked up from roofing materials and atmospheric deposition. Roof runoff controls consist of directing the roof runoff away from paved areas and mitigating flow to the storm drain system through one of several general approaches: cisterns or rain barrels; dry wells or infiltration trenches; pop-up emitters, and foundation planting. The first three approaches require the roof runoff to be contained in a gutter and downspout system. Foundation planting provides a vegetated strip under the drip line of the roof. Approach Design of individual lots for single-family homes as well as lots for higher density residential and commercial structures should consider site design provisions for containing and infiltrating roof runoff or directing roof runoff to vegetative swales or buffer areas. Retained water can be reused for watering gardens, lawns, and trees. Benefits to the environment include reduced demand for potable water used for irrigation, improved stormwater quality, increased groundwater recharge, decreased runoff volume and peak flows, and decreased flooding potential. Suitable Applications Appropriate applications include residential, commercial and industrial areas planned for development or redevelopment. Design Considerations Designing New Installations Cisterns or Rain Barrels One method of addressing roof runoff is to direct roof downspouts to cisterns or rain barrels. A cistern is an above ground storage vessel with either a manually operated valve or a permanently open outlet. Roof runoff is temporarily stored and then released for irrigation or infiltration between storms. The number of rain Design Objectives ; Maximize Infiltration ; Provide Retention ; Slow Runoff Minimize Impervious Land Coverage Prohibit Dumping of Improper Materials ; Contain Pollutants Collect and Convey Rain Garden SD-11 Roof Runoff Controls 2 of 3 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbook.com barrels needed is a function of the rooftop area. Some low impact developers recommend that every house have at least 2 rain barrels, with a minimum storage capacity of 1000 liters. Roof barrels serve several purposes including mitigating the first flush from the roof which has a high volume, amount of contaminants, and thermal load. Several types of rain barrels are commercially available. Consideration must be given to selecting rain barrels that are vector proof and childproof. In addition, some barrels are designed with a bypass valve that filters out grit and other contaminants and routes overflow to a soak-away pit or rain garden. If the cistern has an operable valve, the valve can be closed to store stormwater for irrigation or infiltration between storms. This system requires continual monitoring by the resident or grounds crews, but provides greater flexibility in water storage and metering. If a cistern is provided with an operable valve and water is stored inside for long periods, the cistern must be covered to prevent mosquitoes from breeding. A cistern system with a permanently open outlet can also provide for metering stormwater runoff. If the cistern outlet is significantly smaller than the size of the downspout inlet (say ¼ to ½ inch diameter), runoff will build up inside the cistern during storms, and will empty out slowly after peak intensities subside. This is a feasible way to mitigate the peak flow increases caused by rooftop impervious land coverage, especially for the frequent, small storms. Dry wells and Infiltration Trenches Roof downspouts can be directed to dry wells or infiltration trenches. A dry well is constructed by excavating a hole in the ground and filling it with an open graded aggregate, and allowing the water to fill the dry well and infiltrate after the storm event. An underground connection from the downspout conveys water into the dry well, allowing it to be stored in the voids. To minimize sedimentation from lateral soil movement, the sides and top of the stone storage matrix can be wrapped in a permeable filter fabric, though the bottom may remain open. A perforated observation pipe can be inserted vertically into the dry well to allow for inspection and maintenance. In practice, dry wells receiving runoff from single roof downspouts have been successful over long periods because they contain very little sediment. They must be sized according to the amount of rooftop runoff received, but are typically 4 to 5 feet square, and 2 to 3 feet deep, with a minimum of 1-foot soil cover over the top (maximum depth of 10 feet). To protect the foundation, dry wells must be set away from the building at least 10 feet. They must be installed in solids that accommodate infiltration. In poorly drained soils, dry wells have very limited feasibility. Infiltration trenches function in a similar manner and would be particularly effective for larger roof areas. An infiltration trench is a long, narrow, rock-filled trench with no outlet that receives stormwater runoff. These are described under Treatment Controls. Pop-up Drainage Emitter Roof downspouts can be directed to an underground pipe that daylights some distance from the building foundation, releasing the roof runoff through a pop-up emitter. Similar to a pop-up irrigation head, the emitter only opens when there is flow from the roof. The emitter remains flush to the ground during dry periods, for ease of lawn or landscape maintenance. Roof Runoff Controls SD-11 January 2003 California Stormwater BMP Handbook 3 of 3 New Development and Redevelopment www.cabmphandbook.com Foundation Planting Landscape planting can be provided around the base to allow increased opportunities for stormwater infiltration and protect the soil from erosion caused by concentrated sheet flow coming off the roof. Foundation plantings can reduce the physical impact of water on the soil and provide a subsurface matrix of roots that encourage infiltration. These plantings must be sturdy enough to tolerate the heavy runoff sheet flows, and periodic soil saturation. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) define “redevelopment” in terms of amounts of additional impervious area, increases in gross floor area and/or exterior construction, and land disturbing activities with structural or impervious surfaces. The definition of “ redevelopment” must be consulted to determine whether or not the requirements for new development apply to areas intended for redevelopment. If the definition applies, the steps outlined under “designing new installations” above should be followed.

Approach Project plan designs for development and redevelopment should include application methods of irrigation water that minimize runoff of excess irrigation water into the stormwater conveyance system. Suitable Applications Appropriate applications include residential, commercial and industrial areas planned for development or redevelopment. (Detached residential single-family homes are typically excluded from this requirement.) Design Considerations Designing New Installations The following methods to reduce excessive irrigation runoff should be considered, and incorporated and implemented where determined applicable and feasible by the Permittee: Employ rain-triggered shutoff devices to prevent irrigation after precipitation. Design irrigation systems to each landscape area’s specific water requirements. Include design featuring flow reducers or shutoff valves triggered by a pressure drop to control water loss in the event of broken sprinkler heads or lines.

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

Storm Drain Signage SD-13 January 2003 California Stormwater BMP Handbook 1 of 2 New Development and Redevelopment www.cabmphandbooks.com Description Waste materials dumped into storm drain inlets can have severe impacts on receiving and ground waters. Posting notices regarding discharge prohibitions at storm drain inlets can prevent waste dumping. Storm drain signs and stencils are highly visible source controls that are typically placed directly adjacent to storm drain inlets. Approach The stencil or affixed sign contains a brief statement that prohibits dumping of improper materials into the urban runoff conveyance system. Storm drain messages have become a popular method of alerting the public about the effects of and the prohibitions against waste disposal. Suitable Applications Stencils and signs alert the public to the destination of pollutants discharged to the storm drain. Signs are appropriate in residential, commercial, and industrial areas, as well as any other area where contributions or dumping to storm drains is likely. Design Considerations Storm drain message markers or placards are recommended at all storm drain inlets within the boundary of a development project. The marker should be placed in clear sight facing toward anyone approaching the inlet from either side. All storm drain inlet locations should be identified on the development site map. Designing New Installations The following methods should be considered for inclusion in the project design and show on project plans: Provide stenciling or labeling of all storm drain inlets and catch basins, constructed or modified, within the project area with prohibitive language. Examples include “NO DUMPING Design Objectives Maximize Infiltration Provide Retention Slow Runoff Minimize Impervious Land Coverage ; Prohibit Dumping of Improper Materials Contain Pollutants Collect and Convey SD-13 Storm Drain Signage 2 of 2 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com – DRAINS TO OCEAN” and/or other graphical icons to discourage illegal dumping. Post signs with prohibitive language and/or graphical icons, which prohibit illegal dumping at public access points along channels and creeks within the project area. Note - Some local agencies have approved specific signage and/or storm drain message placards for use. Consult local agency stormwater staff to determine specific requirements for placard types and methods of application. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) define “redevelopment” in terms of amounts of additional impervious area, increases in gross floor area and/or exterior construction, and land disturbing activities with structural or impervious surfaces. If the project meets the definition of “redevelopment”, then the requirements stated under “ designing new installations” above should be included in all project design plans. Additional Information Maintenance Considerations Legibility of markers and signs should be maintained. If required by the agency with jurisdiction over the project, the owner/operator or homeowner’s association should enter into a maintenance agreement with the agency or record a deed restriction upon the property title to maintain the legibility of placards or signs. Placement Signage on top of curbs tends to weather and fade. Signage on face of curbs tends to be worn by contact with vehicle tires and sweeper brooms. Supplemental Information Examples Most MS4 programs have storm drain signage programs. Some MS4 programs will provide stencils, or arrange for volunteers to stencil storm drains as part of their outreach program.

Fueling Areas SD-30 January 2003 California Stormwater BMP Handbook 1 of 3 New Development and Redevelopment www.cabmphandbooks.com Description Fueling areas have the potential to contribute oil and grease, solvents, car battery acid, coolant and gasoline to the stormwater conveyance system. Spills at vehicle and equipment fueling areas can be a significant source of pollution because fuels contain toxic materials and heavy metals that are not easily removed by stormwater treatment devices. Approach Project plans must be developed for cleaning near fuel dispensers, emergency spill cleanup, containment, and leak prevention. Suitable Applications Appropriate applications include commercial, industrial, and any other areas planned to have fuel dispensing equipment, including retail gasoline outlets, automotive repair shops, and major non-retail dispensing areas. Design Considerations Design requirements for fueling areas are governed by Building and Fire Codes and by current local agency ordinances and zoning requirements. Design requirements described in this fact sheet are meant to enhance and be consistent with these code and ordinance requirements. Designing New Installations Covering Design Objectives Maximize Infiltration Provide Retention Slow Runoff Minimize Impervious Land Coverage Prohibit Dumping of Improper Materials ; Contain Pollutants ; Collect and Convey Photo Credit: Geoff Brosseau SD-30 Fueling Areas 2 of 3 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Fuel dispensing areas should provide an overhanging roof structure or canopy. The cover’s minimum dimensions must be equal to or greater than the area within the grade break. The cover must not drain onto the fuel dispensing area and the downspouts must be routed to prevent drainage across the fueling area. The fueling area should drain to the project’s treatment control BMP(s) prior to discharging to the stormwater conveyance system. Note - If fueling large equipment or vehicles that would prohibit the use of covers or roofs, the fueling island should be designed to sufficiently accommodate the larger vehicles and equipment and to prevent stormwater run-on and runoff. Grade to direct stormwater to a dead-end sump. Surfacing Fuel dispensing areas should be paved with Portland cement concrete (or equivalent smooth impervious surface). The use of asphalt concrete should be prohibited. Use asphalt sealant to protect asphalt paved areas surrounding the fueling area. This provision may be made to sites that have pre-existing asphalt surfaces. The concrete fuel dispensing area should be extended a minimum of 6.5 ft from the corner of each fuel dispenser, or the length at which the hose and nozzle assembly may be operated plus 1 ft, whichever is less. Grading/Contouring Dispensing areas should have an appropriate slope to prevent ponding, and be separated from the rest of the site by a grade break that prevents run-on of urban runoff. (Slope is required to be 2 to 4% in some jurisdictions’ stormwater management and mitigation plans.) Fueling areas should be graded to drain toward a dead-end sump. Runoff from downspouts/roofs should be directed away from fueling areas. Do not locate storm drains in the immediate vicinity of the fueling area. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) define “redevelopment” in terms of amounts of additional impervious area, increases in gross floor area and/or exterior construction, and land disturbing activities with structural or impervious surfaces. The definition of “ redevelopment” must be consulted to determine whether or not the requirements for new development apply to areas intended for redevelopment.

Trash Storage Areas SD-32 January 2003 California Stormwater BMP Handbook 1 of 2 New Development and Redevelopment www.cabmphandbooks.com Description Trash storage areas are areas where a trash receptacle (s) are located for use as a repository for solid wastes. Stormwater runoff from areas where trash is stored or disposed of can be polluted. In addition, loose trash and debris can be easily transported by water or wind into nearby storm drain inlets, channels, and/or creeks. Waste handling operations that may be sources of stormwater pollution include dumpsters, litter control, and waste piles. Approach This fact sheet contains details on the specific measures required to prevent or reduce pollutants in stormwater runoff associated with trash storage and handling. Preventative measures including enclosures, containment structures, and impervious pavements to mitigate spills, should be used to reduce the likelihood of contamination. Suitable Applications Appropriate applications include residential, commercial and industrial areas planned for development or redevelopment. (Detached residential single-family homes are typically excluded from this requirement.) Design Considerations Design requirements for waste handling areas are governed by Building and Fire Codes, and by current local agency ordinances and zoning requirements. The design criteria described in this fact sheet are meant to enhance and be consistent with these code and ordinance requirements. Hazardous waste should be handled in accordance with legal requirements established in Title 22, California Code of Regulation. Wastes from commercial and industrial sites are typically hauled by either public or commercial carriers that may have design or access requirements for waste storage areas. The design criteria in this fact sheet are recommendations and are not intended to be in conflict with requirements established by the waste hauler. The waste hauler should be contacted prior to the design of your site trash collection areas. Conflicts or issues should be discussed with the local agency. Designing New Installations Trash storage areas should be designed to consider the following structural or treatment control BMPs: Design trash container areas so that drainage from adjoining roofs and pavement is diverted around the area(s) to avoid run-on. This might include berming or grading the waste handling area to prevent run-on of stormwater. Make sure trash container areas are screened or walled to prevent off-site transport of trash. Design Objectives Maximize Infiltration Provide Retention Slow Runoff Minimize Impervious Land Coverage Prohibit Dumping of Improper Materials ; Contain Pollutants Collect and Convey SD-32 Trash Storage Areas 2 of 2 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Use lined bins or dumpsters to reduce leaking of liquid waste. Provide roofs, awnings, or attached lids on all trash containers to minimize direct precipitation and prevent rainfall from entering containers. Pave trash storage areas with an impervious surface to mitigate spills. Do not locate storm drains in immediate vicinity of the trash storage area. Post signs on all dumpsters informing users that hazardous materials are not to be disposed of therein. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) define “redevelopment” in terms of amounts of additional impervious area, increases in gross floor area and/or exterior construction, and land disturbing activities with structural or impervious surfaces. The definition of “ redevelopment” must be consulted to determine whether or not the requirements for new development apply to areas intended for redevelopment. If the definition applies, the steps outlined under “designing new installations” above should be followed. Additional Information Maintenance Considerations The integrity of structural elements that are subject to damage (i.e., screens, covers, and signs) must be maintained by the owner/operator. Maintenance agreements between the local agency and the owner/operator may be required. Some agencies will require maintenance deed restrictions to be recorded of the property title. If required by the local agency, maintenance agreements or deed restrictions must be executed by the owner/operator before improvement plans are approved.

Vehicle Washing Areas SD-33 January 2003 California Stormwater BMP Handbook 1 of 2 New Development and Redevelopment www.cabmphandbooks.com Description Vehicle washing, equipment washing, and steam cleaning may contribute high concentrations of metals, oil and grease, solvents, phosphates, and suspended solids to wash waters that drain to stormwater conveyance systems. Approach Project plans should include appropriately designed area(s) for washing-steam cleaning of vehicles and equipment. Depending on the size and other parameters of the wastewater facility, wash water may be conveyed to a sewer, an infiltration system, recycling system or other alternative. Pretreatment may be required for conveyance to a sanitary sewer. Suitable Applications Appropriate applications include commercial developments, restaurants, retail gasoline outlets, automotive repair shops and others. Design Considerations Design requirements for vehicle maintenance are governed by Building and Fire Codes, and by current local agency ordinances, and zoning requirements. Design criteria described in this fact sheet are meant to enhance and be consistent with these code requirements. Designing New Installations Areas for washing/steam cleaning should incorporate one of the following features: Be self-contained and/or covered with a roof or overhang Be equipped with a clarifier or other pretreatment facility Have a proper connection to a sanitary sewer Design Objectives ; Maximize Infiltration Provide Retention Slow Runoff Minimize Impervious Land Coverage Prohibit Dumping of Improper Materials ; Contain Pollutants ; Collect and Convey Photo Credit: Geoff Brosseau SD-33 Vehicle Washing Areas 2 of 2 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Include other features which are comparable and equally effective CAR WASH AREAS - Some jurisdictions’ stormwater management plans include vehicle- cleaning area source control design requirements for community car wash racks in complexes with a large number of dwelling units. In these cases, wash water from the areas may be directed to the sanitary sewer, to an engineered infiltration system, or to an equally effective alternative. Pre-treatment may also be required. Depending on the jurisdiction, developers may be directed to divert surface water runoff away from the exposed area around the wash pad ( parking lot, storage areas), and wash pad itself to alternatives other than the sanitary sewer. Roofing may be required for exposed wash pads. It is generally advisable to cover areas used for regular washing of vehicles, trucks, or equipment, surround them with a perimeter berm, and clearly mark them as a designated washing area. Sumps or drain lines can be installed to collect wash water, which may be treated for reuse or recycling, or for discharge to the sanitary sewer. Jurisdictions may require some form of pretreatment, such as a trap, for these areas. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) define “redevelopment” in terms of amounts of additional impervious area, increases in gross floor area and/or exterior construction, and land disturbing activities with structural or impervious surfaces. The definition of “ redevelopment” must be consulted to determine whether or not the requirements for new development apply to areas intended for redevelopment. Additional Information Maintenance Considerations Stormwater and non-stormwater will accumulate in containment areas and sumps with impervious surfaces. Contaminated accumulated water must be disposed of in accordance with applicable laws and cannot be discharged directly to the storm drain or sanitary sewer system without the appropriate permit.

Bioretention TC-32 January 2003 California Stormwater BMP Handbook 1 of 8 New Development and Redevelopment www.cabmphandbooks.com Description The bioretention best management practice (BMP) functions as a soil and plant-based filtration device that removes pollutants through a variety of physical, biological, and chemical treatment processes. These facilities normally consist of a grass buffer strip, sand bed, ponding area, organic layer or mulch layer, planting soil, and plants. The runoff’s velocity is reduced by passing over or through buffer strip and subsequently distributed evenly along a ponding area. Exfiltration of the stored water in the bioretention area planting soil into the underlying soils occurs over a period of days. California Experience None documented. Bioretention has been used as a stormwater BMP since 1992. In addition to Prince George's County, MD and Alexandria, VA, bioretention has been used successfully at urban and suburban areas in Montgomery County, MD; Baltimore County, MD; Chesterfield County, VA; Prince William County, VA; Smith Mountain Lake State Park, VA; and Cary, NC. Advantages Bioretention provides stormwater treatment that enhances the quality of downstream water bodies by temporarily storing runoff in the BMP and releasing it over a period of four days to the receiving water (EPA, 1999). The vegetation provides shade and wind breaks, absorbs noise, and improves an area's landscape. Limitations The bioretention BMP is not recommended for areas with slopes greater than 20% or where mature tree removal would Design Considerations Soil for Infiltration Tributary Area Slope Aesthetics Environmental Side-effects Targeted Constituents Sediment Nutrients ▲ Trash Metals Bacteria Oil and Grease Organics Legend (Removal Effectiveness) z Low High ▲ Medium TC-32 Bioretention 2 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com be required since clogging may result, particularly if the BMP receives runoff with high sediment loads (EPA, 1999). Bioretention is not a suitable BMP at locations where the water table is within 6 feet of the ground surface and where the surrounding soil stratum is unstable. By design, bioretention BMPs have the potential to create very attractive habitats for mosquitoes and other vectors because of highly organic, often heavily vegetated areas mixed with shallow water. In cold climates the soil may freeze, preventing runoff from infiltrating into the planting soil. Design and Sizing Guidelines The bioretention area should be sized to capture the design storm runoff. In areas where the native soil permeability is less than 0.5 in/hr an underdrain should be provided. Recommended minimum dimensions are 15 feet by 40 feet, although the preferred width is 25 feet. Excavated depth should be 4 feet. Area should drain completely within 72 hours. Approximately 1 tree or shrub per 50 ft2 of bioretention area should be included. Cover area with about 3 inches of mulch. Construction/Inspection Considerations Bioretention area should not be established until contributing watershed is stabilized. Performance Bioretention removes stormwater pollutants through physical and biological processes, including adsorption, filtration, plant uptake, microbial activity, decomposition, sedimentation and volatilization (EPA, 1999). Adsorption is the process whereby particulate pollutants attach to soil (e.g., clay) or vegetation surfaces. Adequate contact time between the surface and pollutant must be provided for in the design of the system for this removal process to occur. Thus, the infiltration rate of the soils must not exceed those specified in the design criteria or pollutant removal may decrease. Pollutants removed by adsorption include metals, phosphorus, and hydrocarbons. Filtration occurs as runoff passes through the bioretention area media, such as the sand bed, ground cover, and planting soil. Common particulates removed from stormwater include particulate organic matter, phosphorus, and suspended solids. Biological processes that occur in wetlands result in pollutant uptake by plants and microorganisms in the soil. Plant growth is sustained by the uptake of nutrients from the soils, with woody plants locking up these nutrients through the seasons. Microbial activity within the soil also contributes to the removal of nitrogen and organic matter. Nitrogen is removed by nitrifying and denitrifying bacteria, while aerobic bacteria are responsible for the decomposition of the organic matter. Microbial processes require oxygen and can result in depleted oxygen levels if the bioretention area is not adequately Bioretention TC-32 January 2003 California Stormwater BMP Handbook 3 of 8 New Development and Redevelopment www.cabmphandbooks.com aerated. Sedimentation occurs in the swale or ponding area as the velocity slows and solids fall out of suspension. The removal effectiveness of bioretention has been studied during field and laboratory studies conducted by the University of Maryland (Davis et al, 1998). During these experiments, synthetic stormwater runoff was pumped through several laboratory and field bioretention areas to simulate typical storm events in Prince George's County, MD. Removal rates for heavy metals and nutrients are shown in Table 1. Table 1 Laboratory and Estimated Bioretention Davis et al. (1998); PGDER (1993) Pollutant Removal Rate Total Phosphorus 70-83% Metals (Cu, Zn, Pb) 93-98% TKN 68-80% Total Suspended Solids 90% Organics 90% Bacteria 90% Results for both the laboratory and field experiments were similar for each of the pollutants analyzed. Doubling or halving the influent pollutant levels had little effect on the effluent pollutants concentrations (Davis et al, 1998). The microbial activity and plant uptake occurring in the bioretention area will likely result in higher removal rates than those determined for infiltration BMPs. Siting Criteria Bioretention BMPs are generally used to treat stormwater from impervious surfaces at commercial, residential, and industrial areas (EPA, 1999). Implementation of bioretention for stormwater management is ideal for median strips, parking lot islands, and swales. Moreover, the runoff in these areas can be designed to either divert directly into the bioretention area or convey into the bioretention area by a curb and gutter collection system. The best location for bioretention areas is upland from inlets that receive sheet flow from graded areas and at areas that will be excavated (EPA, 1999). In order to maximize treatment effectiveness, the site must be graded in such a way that minimizes erosive conditions as sheet flow is conveyed to the treatment area. Locations where a bioretention area can be readily incorporated into the site plan without further environmental damage are preferred. Furthermore, to effectively minimize sediment loading in the treatment area, bioretention only should be used in stabilized drainage areas. TC-32 Bioretention 4 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Additional Design Guidelines The layout of the bioretention area is determined after site constraints such as location of utilities, underlying soils, existing vegetation, and drainage are considered (EPA, 1999). Sites with loamy sand soils are especially appropriate for bioretention because the excavated soil can be backfilled and used as the planting soil, thus eliminating the cost of importing planting soil. The use of bioretention may not be feasible given an unstable surrounding soil stratum, soils with clay content greater than 25 percent, a site with slopes greater than 20 percent, and/or a site with mature trees that would be removed during construction of the BMP. Bioretention can be designed to be off-line or on-line of the existing drainage system (EPA, 1999). The drainage area for a bioretention area should be between 0.1 and 0.4 hectares (0.25 and 1.0 acres). Larger drainage areas may require multiple bioretention areas. Furthermore, the maximum drainage area for a bioretention area is determined by the expected rainfall intensity and runoff rate. Stabilized areas may erode when velocities are greater than 5 feet per second (1.5 meter per second). The designer should determine the potential for erosive conditions at the site. The size of the bioretention area, which is a function of the drainage area and the runoff generated from the area is sized to capture the water quality volume. The recommended minimum dimensions of the bioretention area are 15 feet (4.6 meters) wide by 40 feet (12.2 meters) long, where the minimum width allows enough space for a dense, randomly-distributed area of trees and shrubs to become established. Thus replicating a natural forest and creating a microclimate, thereby enabling the bioretention area to tolerate the effects of heat stress, acid rain, runoff pollutants, and insect and disease infestations which landscaped areas in urban settings typically are unable to tolerate. The preferred width is 25 feet (7.6 meters), with a length of twice the width. Essentially, any facilities wider than 20 feet (6.1 meters) should be twice as long as they are wide, which promotes the distribution of flow and decreases the chances of concentrated flow. In order to provide adequate storage and prevent water from standing for excessive periods of time the ponding depth of the bioretention area should not exceed 6 inches (15 centimeters). Water should not be left to stand for more than 72 hours. A restriction on the type of plants that can be used may be necessary due to some plants’ water intolerance. Furthermore, if water is left standing for longer than 72 hours mosquitoes and other insects may start to breed. The appropriate planting soil should be backfilled into the excavated bioretention area. Planting soils should be sandy loam, loamy sand, or loam texture with a clay content ranging from 10 to 25 percent. Generally the soil should have infiltration rates greater than 0.5 inches (1.25 centimeters) per hour, which is typical of sandy loams, loamy sands, or loams. The pH of the soil should range between 5.5 and 6.5, where pollutants such as organic nitrogen and phosphorus can be adsorbed by the soil and microbial activity can flourish. Additional requirements for the planting soil include a 1.5 to 3 percent organic content and a maximum 500 ppm concentration of soluble salts. Bioretention TC-32 January 2003 California Stormwater BMP Handbook 5 of 8 New Development and Redevelopment www.cabmphandbooks.com Soil tests should be performed for every 500 cubic yards (382 cubic meters) of planting soil, with the exception of pH and organic content tests, which are required only once per bioretention area (EPA, 1999). Planting soil should be 4 inches (10.1 centimeters) deeper than the bottom of the largest root ball and 4 feet (1.2 meters) altogether. This depth will provide adequate soil for the plants' root systems to become established, prevent plant damage due to severe wind, and provide adequate moisture capacity. Most sites will require excavation in order to obtain the recommended depth. Planting soil depths of greater than 4 feet (1.2 meters) may require additional construction practices such as shoring measures (EPA, 1999). Planting soil should be placed in 18 inches or greater lifts and lightly compacted until the desired depth is reached. Since high canopy trees may be destroyed during maintenance the bioretention area should be vegetated to resemble a terrestrial forest community ecosystem that is dominated by understory trees. Three species each of both trees and shrubs are recommended to be planted at a rate of 2500 trees and shrubs per hectare (1000 per acre). For instance, a 15 foot (4.6 meter) by 40 foot (12.2 meter) bioretention area (600 square feet or 55.75 square meters) would require 14 trees and shrubs. The shrub-to-tree ratio should be 2:1 to 3:1. Trees and shrubs should be planted when conditions are favorable. Vegetation should be watered at the end of each day for fourteen days following its planting. Plant species tolerant of pollutant loads and varying wet and dry conditions should be used in the bioretention area. The designer should assess aesthetics, site layout, and maintenance requirements when selecting plant species. Adjacent non-native invasive species should be identified and the designer should take measures, such as providing a soil breach to eliminate the threat of these species invading the bioretention area. Regional landscaping manuals should be consulted to ensure that the planting of the bioretention area meets the landscaping requirements established by the local authorities. The designers should evaluate the best placement of vegetation within the bioretention area. Plants should be placed at irregular intervals to replicate a natural forest. Trees should be placed on the perimeter of the area to provide shade and shelter from the wind. Trees and shrubs can be sheltered from damaging flows if they are placed away from the path of the incoming runoff. In cold climates, species that are more tolerant to cold winds, such as evergreens, should be placed in windier areas of the site. Following placement of the trees and shrubs, the ground cover and/or mulch should be established. Ground cover such as grasses or legumes can be planted at the beginning of the growing season. Mulch should be placed immediately after trees and shrubs are planted. Two to 3 inches (5 to 7.6 cm) of commercially-available fine shredded hardwood mulch or shredded hardwood chips should be applied to the bioretention area to protect from erosion. Maintenance The primary maintenance requirement for bioretention areas is that of inspection and repair or replacement of the treatment area's components. Generally, this involves nothing more than the routine periodic maintenance that is required of any landscaped area. Plants that are appropriate for the site, climatic, and watering conditions should be selected for use in the bioretention cell. Appropriately selected plants will aide in reducing fertilizer, pesticide, water, and overall maintenance requirements. Bioretention system components should blend over time through plant and root growth, organic decomposition, and the development of a natural TC-32 Bioretention 6 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com soil horizon. These biologic and physical processes over time will lengthen the facility's life span and reduce the need for extensive maintenance. Routine maintenance should include a biannual health evaluation of the trees and shrubs and subsequent removal of any dead or diseased vegetation (EPA, 1999). Diseased vegetation should be treated as needed using preventative and low-toxic measures to the extent possible. BMPs have the potential to create very attractive habitats for mosquitoes and other vectors because of highly organic, often heavily vegetated areas mixed with shallow water. Routine inspections for areas of standing water within the BMP and corrective measures to restore proper infiltration rates are necessary to prevent creating mosquito and other vector habitat. In addition, bioretention BMPs are susceptible to invasion by aggressive plant species such as cattails, which increase the chances of water standing and subsequent vector production if not routinely maintained. In order to maintain the treatment area’s appearance it may be necessary to prune and weed. Furthermore, mulch replacement is suggested when erosion is evident or when the site begins to look unattractive. Specifically, the entire area may require mulch replacement every two to three years, although spot mulching may be sufficient when there are random void areas. Mulch replacement should be done prior to the start of the wet season. New Jersey's Department of Environmental Protection states in their bioretention systems standards that accumulated sediment and debris removal (especially at the inflow point) will normally be the primary maintenance function. Other potential tasks include replacement of dead vegetation, soil pH regulation, erosion repair at inflow points, mulch replenishment, unclogging the underdrain, and repairing overflow structures. There is also the possibility that the cation exchange capacity of the soils in the cell will be significantly reduced over time. Depending on pollutant loads, soils may need to be replaced within 5-10 years of construction (LID, 2000). Cost Construction Cost Construction cost estimates for a bioretention area are slightly greater than those for the required landscaping for a new development (EPA, 1999). A general rule of thumb (Coffman, 1999) is that residential bioretention areas average about $3 to $4 per square foot, depending on soil conditions and the density and types of plants used. Commercial, industrial and institutional site costs can range between $10 to $40 per square foot, based on the need for control structures, curbing, storm drains and underdrains. Retrofitting a site typically costs more, averaging $6,500 per bioretention area. The higher costs are attributed to the demolition of existing concrete, asphalt, and existing structures and the replacement of fill material with planting soil. The costs of retrofitting a commercial site in Maryland, Kettering Development, with 15 bioretention areas were estimated at $111,600. In any bioretention area design, the cost of plants varies substantially and can account for a significant portion of the expenditures. While these cost estimates are slightly greater than those of typical landscaping treatment (due to the increased number of plantings, additional soil excavation, backfill material, use of underdrains etc.), those landscaping expenses that would be required regardless of the bioretention installation should be subtracted when determining the net cost. Bioretention TC-32 January 2003 California Stormwater BMP Handbook 7 of 8 New Development and Redevelopment www.cabmphandbooks.com Perhaps of most importance, however, the cost savings compared to the use of traditional structural stormwater conveyance systems makes bioretention areas quite attractive financially. For example, the use of bioretention can decrease the cost required for constructing stormwater conveyance systems at a site. A medical office building in Maryland was able to reduce the amount of storm drain pipe that was needed from 800 to 230 feet - a cost savings of $24,000 (PGDER, 1993). And a new residential development spent a total of approximately $100,000 using bioretention cells on each lot instead of nearly $400,000 for the traditional stormwater ponds that were originally planned (Rappahanock, ). Also, in residential areas, stormwater management controls become a part of each property owner's landscape, reducing the public burden to maintain large centralized facilities. Maintenance Cost The operation and maintenance costs for a bioretention facility will be comparable to those of typical landscaping required for a site. Costs beyond the normal landscaping fees will include the cost for testing the soils and may include costs for a sand bed and planting soil.

WetlandMod’s horizontal design also allows water to consistently flow subsurface, clear of obstructions in a more controlled state. BIOFILTRATION CHAMBER The patented void area maximizes surface area and minimizes footprint, saving space and money. The unique design accomplishes this by allowing water to penetrate the media bed, not only from the top, but from each side. OPERATIONALTERNATIVE DOWNWARD FLOW FLAWS Bioretention systems have an inherent flaw — the force of gravity. As stormwater runoff carries pollutants into the system, including sediments and hydrocarbons, they are deposited on top of the bioretention media where it accumulates and quickly clogs the filter media. It has been documented that sediment accumulation from just a few storm events can completely clog a bioretention system. This leads to drastically reduced infiltration rates, expensive maintenance burdens, and safety issues associated with standing water, depressed landscaping, and vector control. Sediment, trash and debris entering the WetlandMod accumulate adjacent to vertical media surface, reducing clogging. The vertical ponding area (void area) maximizes sedimentation and minimizes clogging issues associated with downward flow bioretention. Top View End View As sediment rapidly builds up on the media bed, flow is impeded and the bioretention system quickly clogs or fails. Downward flow systems filter water in a single vertical direction, forcing polluted material to build up on the top. Notes 1.

CONFIGURATIONS INSTALLATION MAINTENANCE The goal of the WetlandMod system is to minimize footprint and land costs associated with traditional bioretention/biofiltration systems. This is acheived by utilizing horizontal flow technology and combining it with traditional downward flow, therefore maximizing the surface area for a given footprint. WetlandMod is constructed from modular precast concrete structures. The system can be configured as standard curb type, multiple inlet pipes, and/or grate options into the pretreatment chamber with optional internal bypass. The biofiltration chambers can be designed for various length and width combinations (shown below) to allow for easy integration with parking lot island designs. The system comes in two standard widths: 5 feet (18” minimum media requirement - San Diego County and Bay Area Region) and 6 feet (24” minimum media requirement - Los Angeles County). Maximize infiltration levels for all soil conditions. Simple vault and media installation. The average maintenance time is 45 minutes using a standard vacuum truck. All-in-one treatment train, no need for separate trash capture manhole or vault. The WetlandMod is designed for easy hose line access to every debris and sediment chamber. INFILTRATION DESIGN OVERSIZED GRAVEL BASE HIGHLY MODULAR Our standard 6 foot single row and 11 foot double row models, for 24” soil media thickness, are commonly used together to meet wide design requirements and address transportation challenges. A quick and easy maintenance regimen begins with a simple design, and the WetlanMod features benefits that no other bioretention system can replicate. First, the WetlandMod’s pretreatment chamber can be accessed via a manhole cover or grate, providing consolidated access to most of the trash, debris, and sediment. The perimeter void areas are more easily accessible with a conventional vacuum truck, allowing plant beds to remain undisturbed. In areas under C.3 guidance, there is no need for removal and replacement of the 6 inches or more of top soil, so there is no risk of damaging the plants and irrigation systems (if needed) that may occur during the topsoil replacement with a vertical flow planter.

The protocols in this fact sheet are intended to prevent or reduce the discharge of pollutants from parking/storage areas and include using good housekeeping practices, following appropriate cleaning BMPs, and training employees. Approach The goal of this program is to ensure stormwater pollution prevention practices are considered when conducting activities on or around parking areas and storage areas to reduce potential for pollutant discharge to receiving waters. Successful implementation depends on effective training of employees on applicable BMPs and general pollution prevention strategies and objectives. Pollution Prevention Encourage alternative designs and maintenance strategies for impervious parking lots. (See New Development and Redevelopment BMP Handbook) Keep accurate maintenance logs to evaluate BMP implementation. January 2003 California Stormwater BMP Handbook 1 of 4 Industrial and Commercial www.cabmphandbooks.com SC-43 Parking/Storage Area Maintenance Suggested Protocols General Keep the parking and storage areas clean and orderly. Remove debris in a timely fashion. Allow sheet runoff to flow into biofilters (vegetated strip and swale) and/or infiltration devices. Utilize sand filters or oleophilic collectors for oily waste in low quantities. Arrange rooftop drains to prevent drainage directly onto paved surfaces. Design lot to include semi-permeable hardscape. Discharge soapy water remaining in mop or wash buckets to the sanitary sewer through a sink, toilet, clean-out, or wash area with drain. Controlling Litter Post “No Littering” signs and enforce anti-litter laws. Provide an adequate number of litter receptacles. Clean out and cover litter receptacles frequently to prevent spillage. Provide trash receptacles in parking lots to discourage litter. Routinely sweep, shovel, and dispose of litter in the trash. Surface Cleaning Use dry cleaning methods (e.g., sweeping, vacuuming) to prevent the discharge of pollutants into the stormwater conveyance system if possible. Establish frequency of public parking lot sweeping based on usage and field observations of waste accumulation. Sweep all parking lots at least once before the onset of the wet season. Follow the procedures below if water is used to clean surfaces: - Block the storm drain or contain runoff. - Collect and pump wash water to the sanitary sewer or discharge to a pervious surface. Do not allow wash water to enter storm drains. - Dispose of parking lot sweeping debris and dirt at a landfill. Follow the procedures below when cleaning heavy oily deposits: - Clean oily spots with absorbent materials. - Use a screen or filter fabric over inlet, then wash surfaces. 2 of 4 California Stormwater BMP Handbook January 2003 Industrial and Commercial www.cabmphandbooks.com Parking/Storage Area Maintenance SC-43 - Do not allow discharges to the storm drain. - Vacuum/pump discharges to a tank or discharge to sanitary sewer. - Appropriately dispose of spilled materials and absorbents. Surface Repair Preheat, transfer or load hot bituminous material away from storm drain inlets. Apply concrete, asphalt, and seal coat during dry weather to prevent contamination from contacting stormwater runoff. Cover and seal nearby storm drain inlets where applicable (with waterproof material or mesh) and manholes before applying seal coat, slurry seal, etc. Leave covers in place until job is complete and all water from emulsified oil sealants has drained or evaporated. Clean any debris from these covered manholes and drains for proper disposal. Use only as much water as necessary for dust control, to avoid runoff. Catch drips from paving equipment that is not in use with pans or absorbent material placed under the machines. Dispose of collected material and absorbents properly. Inspection Have designated personnel conduct inspections of parking facilities and stormwater conveyance systems associated with parking facilities on a regular basis. Inspect cleaning equipment/sweepers for leaks on a regular basis. Training Provide regular training to field employees and/or contractors regarding cleaning of paved areas and proper operation of equipment. Train employees and contractors in proper techniques for spill containment and cleanup. Spill Response and Prevention Keep your Spill Prevention Control and Countermeasure (SPCC) Plan up-to-date. Place a stockpile of spill cleanup materials where it will be readily accessible or at a central location. Clean up fluid spills immediately with absorbent rags or material. Dispose of spilled material and absorbents properly. Other Considerations Limitations related to sweeping activities at large parking facilities may include high equipment costs, the need for sweeper operator training, and the inability of current sweeper technology to remove oil and grease. January 2003 California Stormwater BMP Handbook 3 of 4 Industrial and Commercial www.cabmphandbooks.com SC-43 Parking/Storage Area Maintenance 4 of 4 California Stormwater BMP Handbook January 2003 Industrial and Commercial www.cabmphandbooks.com Requirements Costs Cleaning/sweeping costs can be quite large. Construction and maintenance of stormwater structural controls can be quite expensive as well. Maintenance Sweep parking lot regularly to minimize cleaning with water. Clean out oil/water/sand separators regularly, especially after heavy storms. Clean parking facilities regularly to prevent accumulated wastes and pollutants from being discharged into conveyance systems during rainy conditions. Supplemental Information Further Detail of the BMP Surface Repair Apply concrete, asphalt, and seal coat during dry weather to prevent contamination from contacting stormwater runoff. Where applicable, cover and seal nearby storm drain inlets (with waterproof material or mesh) and manholes before applying seal coat, slurry seal, etc. Leave covers in place until job is complete and all water from emulsified oil sealants has drained or evaporated. Clean any debris from these covered manholes and drains for proper disposal. Only use only as much water as is necessary for dust control to avoid runoff.

The protocols in this fact sheet are intended to reduce pollutants reaching receiving waters through proper conveyance system operation and maintenance. Approach Pollution Prevention Maintain catch basins, stormwater inlets, and other stormwater conveyance structures on a regular basis to remove pollutants, reduce high pollutant concentrations during the first flush of storms, prevent clogging of the downstream conveyance system, restore catch basins’ sediment trapping capacity, and ensure the system functions properly hydraulically to avoid flooding. Suggested Protocols Catch Basins/Inlet Structures Staff should regularly inspect facilities to ensure compliance with the following: - Immediate repair of any deterioration threatening structural integrity. - Cleaning before the sump is 40% full. Catch basins should be cleaned as frequently as needed to meet this standard. - Stenciling of catch basins and inlets (see SC34 Waste Handling and Disposal). January 2003 California Stormwater BMP Handbook 1 of 6 Industrial and Commercial www.cabmphandbooks.com SC-44 Drainage System Maintenance Clean catch basins, storm drain inlets, and other conveyance structures before the wet season to remove sediments and debris accumulated during the summer. Conduct inspections more frequently during the wet season for problem areas where sediment or trash accumulates more often. Clean and repair as needed. Keep accurate logs of the number of catch basins cleaned. Store wastes collected from cleaning activities of the drainage system in appropriate containers or temporary storage sites in a manner that prevents discharge to the storm drain. Dewater the wastes if necessary with outflow into the sanitary sewer if permitted. Water should be treated with an appropriate filtering device prior to discharge to the sanitary sewer. If discharge to the sanitary sewer is not allowed, water should be pumped or vacuumed to a tank and properly disposed. Do not dewater near a storm drain or stream. Storm Drain Conveyance System Locate reaches of storm drain with deposit problems and develop a flushing schedule that keeps the pipe clear of excessive buildup. Collect and pump flushed effluent to the sanitary sewer for treatment whenever possible. Pump Stations Clean all storm drain pump stations prior to the wet season to remove silt and trash. Do not allow discharge to reach the storm drain system when cleaning a storm drain pump station or other facility. Conduct routine maintenance at each pump station. Inspect, clean, and repair as necessary all outlet structures prior to the wet season. Open Channel Modify storm channel characteristics to improve channel hydraulics, increase pollutant removals, and enhance channel/creek aesthetic and habitat value. Conduct channel modification/improvement in accordance with existing laws. Any person, government agency, or public utility proposing an activity that will change the natural (emphasis added) state of any river, stream, or lake in California, must enter into a Steam or Lake Alteration Agreement with the Department of Fish and Game. The developer-applicant should also contact local governments (city, county, special districts), other state agencies (SWRCB, RWQCB, Department of Forestry, Department of Water Resources), and Federal Corps of Engineers and USFWS. Illicit Connections and Discharges Look for evidence of illegal discharges or illicit connections during routine maintenance of conveyance system and drainage structures: - Is there evidence of spills such as paints, discoloring, etc? 2 of 6 California Stormwater BMP Handbook January 2003 Industrial and Commercial www.cabmphandbooks.com Drainage System Maintenance SC-44 - Are there any odors associated with the drainage system? - Record locations of apparent illegal discharges/illicit connections? - Track flows back to potential dischargers and conduct aboveground inspections. This can be done through visual inspection of upgradient manholes or alternate techniques including zinc chloride smoke testing, fluorometric dye testing, physical inspection testing, or television camera inspection. - Eliminate the discharge once the origin of flow is established. Stencil or demarcate storm drains, where applicable, to prevent illegal disposal of pollutants. Storm drain inlets should have messages such as “Dump No Waste Drains to Stream” stenciled next to them to warn against ignorant or intentional dumping of pollutants into the storm drainage system. Refer to fact sheet SC-10 Non-Stormwater Discharges. Illegal Dumping Inspect and clean up hot spots and other storm drainage areas regularly where illegal dumping and disposal occurs. Establish a system for tracking incidents. The system should be designed to identify the following: - Illegal dumping hot spots - Types and quantities (in some cases) of wastes - Patterns in time of occurrence (time of day/night, month, or year) - Mode of dumping (abandoned containers, “midnight dumping” from moving vehicles, direct dumping of materials, accidents/spills) - Responsible parties Post “No Dumping” signs in problem areas with a phone number for reporting dumping and disposal. Signs should also indicate fines and penalties for illegal dumping. Refer to fact sheet SC-10 Non-Stormwater Discharges. Training Train crews in proper maintenance activities, including record keeping and disposal. Allow only properly trained individuals to handle hazardous materials/wastes. Have staff involved in detection and removal of illicit connections trained in the following: - OSHA-required Health and Safety Training (29 CFR 1910.120) plus annual refresher training (as needed). January 2003 California Stormwater BMP Handbook 3 of 6 Industrial and Commercial www.cabmphandbooks.com SC-44 Drainage System Maintenance - OSHA Confined Space Entry training (Cal-OSHA Confined Space, Title 8 and Federal OSHA 29 CFR 1910.146). - Procedural training (field screening, sampling, smoke/dye testing, TV inspection). Spill Response and Prevention Investigate all reports of spills, leaks, and/or illegal dumping promptly. Clean up all spills and leaks using “dry” methods (with absorbent materials and/or rags) or dig up, remove, and properly dispose of contaminated soil. Refer to fact sheet SC-11 Spill Prevention, Control, and Cleanup. Other Considerations (Limitations and Regulations) Clean-up activities may create a slight disturbance for local aquatic species. Access to items and material on private property may be limited. Trade-offs may exist between channel hydraulics and water quality/riparian habitat. If storm channels or basins are recognized as wetlands, many activities, including maintenance, may be subject to regulation and permitting. Storm drain flushing is most effective in small diameter pipes (36-inch diameter pipe or less, depending on water supply and sediment collection capacity). Other considerations associated with storm drain flushing may include the availability of a water source, finding a downstream area to collect sediments, liquid/sediment disposal, and prohibition against disposal of flushed effluent to sanitary sewer in some areas. Regulations may include adoption of substantial penalties for illegal dumping and disposal. Local municipal codes may include sections prohibiting discharge of soil, debris, refuse, hazardous wastes, and other pollutants into the storm drain system. Requirements Costs An aggressive catch basin cleaning program could require a significant capital and O&M budget. The elimination of illegal dumping is dependent on the availability, convenience, and cost of alternative means of disposal. The primary cost is for staff time. Cost depends on how aggressively a program is implemented. Other cost considerations for an illegal dumping program include: - Purchase and installation of signs. - Rental of vehicle(s) to haul illegally-disposed items and material to landfills. - Rental of heavy equipment to remove larger items (e.g., car bodies) from channels. - Purchase of landfill space to dispose of illegally-dumped items and material. 4 of 6 California Stormwater BMP Handbook January 2003 Industrial and Commercial www.cabmphandbooks.com Drainage System Maintenance SC-44 Methods used for illicit connection detection (smoke testing, dye testing, visual inspection, and flow monitoring) can be costly and time-consuming. Site-specific factors, such as the level of impervious area, the density and ages of buildings, and type of land use will determine the level of investigation necessary. Maintenance Two-person teams may be required to clean catch basins with vactor trucks. Teams of at least two people plus administrative personnel are required to identify illicit discharges, depending on the complexity of the storm sewer system. Arrangements must be made for proper disposal of collected wastes. Technical staff are required to detect and investigate illegal dumping violations. Supplemental Information Further Detail of the BMP Storm Drain Flushing Flushing is a common maintenance activity used to improve pipe hydraulics and to remove pollutants in storm drainage systems. Flushing may be designed to hydraulically convey accumulated material to strategic locations, such as an open channel, another point where flushing will be initiated, or the sanitary sewer and the treatment facilities, thus preventing resuspension and overflow of a portion of the solids during storm events. Flushing prevents “plug flow” discharges of concentrated pollutant loadings and sediments. Deposits can hinder the designed conveyance capacity of the storm drain system and potentially cause backwater conditions in severe cases of clogging. Storm drain flushing usually takes place along segments of pipe with grades that are too flat to maintain adequate velocity to keep particles in suspension. An upstream manhole is selected to place an inflatable device that temporarily plugs the pipe. Further upstream, water is pumped into the line to create a flushing wave. When the upstream reach of pipe is sufficiently full to cause a flushing wave, the inflated device is rapidly deflated with the assistance of a vacuum pump, thereby releasing the backed up water and resulting in the cleaning of the storm drain segment. To further reduce impacts of stormwater pollution, a second inflatable device placed well downstream may be used to recollect the water after the force of the flushing wave has dissipated. A pump may then be used to transfer the water and accumulated material to the sanitary sewer for treatment. In some cases, an interceptor structure may be more practical or required to recollect the flushed waters. It has been found that cleansing efficiency of periodic flush waves is dependent upon flush volume, flush discharge rate, sewer slope, sewer length, sewer flow rate, sewer diameter, and population density. As a rule of thumb, the length of line to be flushed should not exceed 700 feet. At this maximum recommended length, the percent removal efficiency ranges between 65- 75% for organics and 55-65% for dry weather grit/inorganic material. The percent removal efficiency drops rapidly beyond that. Water is commonly supplied by a water truck, but fire hydrants can also supply water. To make the best use of water, it is recommended that reclaimed water be used or that fire hydrant line flushing coincide with storm sewer flushing.

On line: http://www.epa.gov/npdes/menuofbmps/poll_16.htm Landscape Maintenance SC-73 January 2003 California Stormwater BMP Handbook 1 of 6 Municipal www.cabmphandbooks.com Description Landscape maintenance activities include vegetation removal; herbicide and insecticide application; fertilizer application; watering; and other gardening and lawn care practices. Vegetation control typically involves a combination of chemical (herbicide) application and mechanical methods. All of these maintenance practices have the potential to contribute pollutants to the storm drain system. The major objectives of this BMP are to minimize the discharge of pesticides, herbicides and fertilizers to the storm drain system and receiving waters; prevent the disposal of landscape waste into the storm drain system by collecting and properly disposing of clippings and cuttings, and educating employees and the public. Approach Pollution Prevention Implement an integrated pest management (IPM) program. IPM is a sustainable approach to managing pests by combining biological, cultural, physical, and chemical tools. Choose low water using flowers, trees, shrubs, and groundcover. Consider alternative landscaping techniques such as naturescaping and xeriscaping. Conduct appropriate maintenance (i.e. properly timed fertilizing, weeding, pest control, and pruning) to help preserve the landscapes water efficiency. Objectives Contain Educate Reduce/Minimize Product Substitution Targeted Constituents Sediment ; Nutrients ; Trash ; Metals Bacteria Oil and Grease Organics Oxygen Demanding ; SC-73 Landscape Maintenance 2 of 6 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Consider grass cycling (grass cycling is the natural recycling of grass by leaving the clippings on the lawn when mowing. Grass clippings decompose quickly and release valuable nutrients back into the lawn). Suggested Protocols Mowing, Trimming, and Weeding Whenever possible use mechanical methods of vegetation removal (e.g mowing with tractor- type or push mowers, hand cutting with gas or electric powered weed trimmers) rather than applying herbicides. Use hand weeding where practical. Avoid loosening the soil when conducting mech anical or manual weed control, this could lead to erosion. Use mulch or other erosion control measures when soils are exposed. Performing mowing at optimal times. Mowing should not be performed if significant rain events are predicted. Mulching mowers may be recommended for certain flat areas. Other techniques may be employed to minimize mowing such as selective vegetative planting using low maintenance grasses and shrubs. Collect lawn and garden clippings, pruning waste, tree trimmings, and weeds. Chip if necessary, and compost or dispose of at a landfill (see waste management section of this fact sheet). Place temporarily stockpiled material away from watercourses, and berm or cover stockpiles to prevent material releases to storm drains. Planting Determine existing native vegetation features (location, species, size, function, importance) and consider the feasibility of protecting them. Consider elements such as their effect on drainage and erosion, hardiness, maintenance requirements, and possible conflicts between preserving vegetation and the resulting maintenance needs. Retain and/or plant selected native vegetation whose features are determined to be beneficial, where feasible. Native vegetation usually requires less maintenance (e.g., irrigation, fertilizer) than planting new vegetation. Consider using low water use groundcovers when planting or replanting. Waste Management Compost leaves, sticks, or other collected vegetation or dispose of at a permitted landfill. Do not dispose of collected vegetation into waterways or storm drainage systems. Place temporarily stockpiled material away from watercourses and storm drain inlets, and berm or cover stockpiles to prevent material releases to the storm drain system. Reduce the use of high nitrogen fertilizers that produce excess growth requiring more frequent mowing or trimming. Landscape Maintenance SC-73 January 2003 California Stormwater BMP Handbook 3 of 6 Municipal www.cabmphandbooks.com Avoid landscape wastes in and around storm drain inlets by either using bagging equipment or by manually picking up the material. Irrigation Where practical, use automatic timers to minimize runoff. Use popup sprinkler heads in areas with a lot of activity or where there is a chance the pipes may be broken. Consider the use of mechanisms that reduce water flow to sprinkler heads if broken. Ensure that there is no runoff from the landscaped area(s) if re-claimed water is used for irrigation. If bailing of muddy water is required (e.g. when repairing a water line leak), do not put it in the storm drain; pour over landscaped areas. Irrigate slowly or pulse irrigate to prevent runoff and then only irrigate as much as is needed. Apply water at rates that do not exceed the infiltration rate of the soil. Fertilizer and Pesticide Management Utilize a comprehensive management system that incorporates integrated pest management (IPM) techniques. There are many methods and types of IPM, including the following: - Mulching can be used to prevent weeds where turf is absent, fencing installed to keep rodents out, and netting used to keep birds and insects away from leaves and fruit. - Visible insects can be removed by hand (with gloves or tweezers) and placed in soapy water or vegetable oil. Alternatively, insects can be sprayed off the plant with water or in some cases vacuumed off of larger plants. - Store-bought traps, such as species-specific, pheromone-based traps or colored sticky cards, can be used. - Slugs can be trapped in small cups filled with beer that are set in the ground so the slugs can get in easily. - In cases where microscopic parasites, such as bacteria and fungi, are causing damage to plants, the affected plant material can be removed and disposed of (pruning equipment should be disinfected with bleach to prevent spreading the disease organism). - Small mammals and birds can be excluded using fences, netting, tree trunk guards. - Beneficial organisms, such as bats, birds, green lacewings, ladybugs, praying mantis, ground beetles, parasitic nematodes, trichogramma wasps, seed head weevils, and spiders that prey on detrimental pest species can be promoted. Follow all federal, state, and local laws and regulations governing the use, storage, and disposal of fertilizers and pesticides and training of applicators and pest control advisors. SC-73 Landscape Maintenance 4 of 6 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Use pesticides only if there is an actual pest problem (not on a regular preventative schedule). Do not use pesticides if rain is expected. Apply pesticides only when wind speeds are low (less than 5 mph). Do not mix or prepare pesticides for application near storm drains. Prepare the minimum amount of pesticide needed for the job and use the lowest rate that will effectively control the pest. Employ techniques to minimize off-target application (e.g. spray drift) of pesticides, including consideration of alternative application techniques. Fertilizers should be worked into the soil rather than dumped or broadcast onto the surface. Calibrate fertilizer and pesticide application equipment to avoid excessive application. Periodically test soils for determining proper fertilizer use. Sweep pavement and sidewalk if fertilizer is spilled on these surfaces before applying irrigation water. Purchase only the amount of pesticide that you can reasonably use in a given time period (month or year depending on the product). Triple rinse containers, and use rinse water as product. Dispose of unused pesticide as hazardous waste. Dispose of empty pesticide containers according to the instructions on the container label. Inspection Inspect irrigation system periodically to ensure that the right amount of water is being applied and that excessive runoff is not occurring. Minimize excess watering, and repair leaks in the irrigation system as soon as they are observed. Inspect pesticide/fertilizer equipment and transportation vehicles daily. Training Educate and train employees on use of pesticides and in pesticide application techniques to prevent pollution. Pesticide application must be under the supervision of a California qualified pesticide applicator. Train/encourage municipal maintenance crews to use IPM techniques for managing public green areas. Annually train employees within departments responsible for pesticide application on the appropriate portions of the agency’s IPM Policy, SOPs, and BMPs, and the latest IPM techniques. Landscape Maintenance SC-73 January 2003 California Stormwater BMP Handbook 5 of 6 Municipal www.cabmphandbooks.com Employees who are not authorized and trained to apply pesticides should be periodically (at least annually) informed that they cannot use over-the-counter pesticides in or around the workplace. Use a training log or similar method to document training. Spill Response and Prevention Refer to SC-11, Spill Prevention, Control & Cleanup Have spill cleanup materials readily available and in a know in location Cleanup spills immediately and use dry methods if possible. Properly dispose of spill cleanup material. Other Considerations The Federal Pesticide, Fungicide, and Rodenticide Act and California Title 3, Division 6, Pesticides and Pest Control Operations place strict controls over pesticide application and handling and specify training, annual refresher, and testing requirements. The regulations generally cover: a list of approved pesticides and selected uses, updated regularly; general application information; equipment use and maintenance procedures; and record keeping. The California Department of Pesticide Regulations and the County Agricultural Commission coordinate and maintain the licensing and certification programs. All public agency employees who apply pesticides and herbicides in “agricultural use” areas such as parks, golf courses, rights-of-way and recreation areas should be properly certified in accordance with state regulations. Contracts for landscape maintenance should include similar requirements. All employees who handle pesticides should be familiar with the most recent material safety data sheet (MSDS) files. Municipalities do not have the authority to regulate the use of pesticides by school districts, however the California Healthy Schools Act of 2000 (AB 2260) has imposed requirements on California school districts regarding pesticide use in schools. Posting of notification prior to the application of pesticides is now required, and IPM is stated as the preferred approach to pest management in schools. Requirements Costs Additional training of municipal employees will be required to address IPM techniques and BMPs. IPM methods will likely increase labor cost for pest control which may be offset by lower chemical costs. Maintenance Not applicable SC-73 Landscape Maintenance 6 of 6 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Supplemental Information Further Detail of the BMP Waste Management Composting is one of the better disposal alternatives if locally available. Most municipalities either have or are planning yard waste composting facilities as a means of reducing the amount of waste going to the landfill. Lawn clippings from municipal maintenance programs as well as private sources would probably be compatible with most composting facilities Contractors and Other Pesticide Users Municipal agencies should develop and implement a process to ensure that any contractor employed to conduct pest control and pesticide application on municipal property engages in pest control methods consistent with the IPM Policy adopted by the agency. Specifically, municipalities should require contractors to follow the agency’s IPM policy, SOPs, and BMPs; provide evidence to the agency of having received training on current IPM techniques when feasible; provide documentation of pesticide use on agency property to the agency in a timely manner.

Theeffectsofpollution Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater from naturally soaking into the ground. Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing, and providing drinking water. Polluted stormwater runoff can have many adverse effects on plants, fish, animals, and people. Sediment can cloud the water and make it difficult or impossible for aquatic plants to grow. Sediment also can .destroy aquatic habitats Excess nutrients can cause algae blooms. When algae die, they sink to the bottom and decompose in a process that removes oxygen from the water. Fish and other aquatic organisms can’t exist in water with low dissolved oxygen levels. Bacteria and other pathogens can wash into swimming areas and create health hazards, often making beach closures necessary. Debris—plastic bags, six-pack rings, bottles, and cigarette butts—washed into waterbodies can choke, suffocate, or disable aquatic life like ducks, fish, turtles, and birds. Household hazardous wastes like insecticides, pesticides, paint, solvents, used motor oil, and other auto fluids can poison aquatic life. Land animals and people can become sick or die from eating diseased fish and shellfish or ingesting polluted water. Polluted stormwater often affects drinking water sources. This, in turn, can affect human health and increase drinking water treatment costs.AftertheStormEPA 833-B-03-002January 2003For more information contact:or visitwww.epa.gov/npdes/stormwaterwww.epa.gov/npsACitizen’sGuidetoUnderstandingStormwaterWHEN IT RAINSIT DRAINSWHEN IT RAINSIT DRAINSInternet Address (URL) HTTP://www.epa.govRecycled/Recyclable Printed With VegetableOil Based Inks on 100% Postconsumer,Process Chlorine Free Recycled Paper●● Auto care Washing your car and degreasing auto parts at home can send detergents and other contaminants through the storm sewer system. Dumping automotive fluids into storm drains has the same result as dumping the materials directly into a waterbody. Pet waste Pet waste can be a major source of bacteria and excess nutrients in local waters. When walking your pet, remember to pick up the waste and dispose of it properly. Flushing pet waste is the best disposal method. Leaving pet waste on the ground increases public health risks by allowing harmful bacteria and nutrients to wash into the storm drain and eventually into local waterbodies. Septic systems Leaking and poorly maintained septic systems release nutrients and pathogens (bacteria and viruses) that can be picked up by stormwater and discharged into nearby waterbodies. Pathogens can cause public health problems and environmental concerns. Lawn care Excess fertilizers and pesticides applied to lawns and gardens wash off and pollute streams. In addition, yard clippings and leaves can wash into storm drains and contribute nutrients and organic matter to streams. Education is essential to changing people's behavior. Signs and markers near storm drains warn residents that pollutants entering the drains will be carried untreated into a local waterbody.Recycle or properly dispose of household products that contain chemicals, such as insecticides, pesticides, paint, solvents, and used motor oil and other auto fluids. Don’t pour them onto the ground or into storm drains. Use a commercial car wash that treats or recycles its wastewater, or wash your car on your yard so the water infiltrates into the ground. Repair leaks and dispose of used auto fluids and batteries at designated drop-off or recycling locations. Don’t overwater your lawn. Consider using a soaker hose instead of a sprinkler. Use pesticides and fertilizers sparingly. When use is necessary, use these chemicals in the recommended amounts. Use organic mulch or safer pest control methods whenever possible. Compost or mulch yard waste. Don’t leave it in the street or sweep it into storm drains or streams. Cover piles of dirt or mulch being used in landscaping projects. Inspect your system every 3 years and pump your tank as necessary (every 3 to 5 years). Don't dispose of household hazardous waste in sinks or toilets. Dirt, oil, and debris that collect in parking lots and paved areas can be washed into the storm sewer system and eventually enter local waterbodies. Sweep up litter and debris from sidewalks, driveways and parking lots, especially around storm drains. Cover grease storage and dumpsters and keep them clean to avoid leaks. Report any chemical spill to the local hazardous waste cleanup team. They’ll know the best way to keep spills from harming the environment. Erosion controls that aren’t maintained can cause excessive amounts of sediment and debris to be carried into the stormwater system. Construction vehicles can leak fuel, oil, and other harmful fluids that can be picked up by stormwater and deposited into local waterbodies. Divert stormwater away from disturbed or exposed areas of the construction site. Install silt fences, vehicle mud removal areas, vegetative cover, and other sediment and erosion controls and properly maintain them, especially after rainstorms. Prevent soil erosion by minimizing disturbed areas during construction projects, and seed and mulch bare areas as soon as possible. Uncovered fueling stations allow spills to be washed into storm drains. Cars waiting to be repaired can leak fuel, oil, and other harmful fluids that can be picked up by stormwater. Clean up spills immediately and properly dispose of cleanup materials. Provide cover over fueling stations and design or retrofit facilities for spill containment. Properly maintain fleet vehicles to prevent oil, gas, and other discharges from being washed into local waterbodies. Install and maintain oil/water separators. Lack of vegetation on streambanks can lead to erosion. Overgrazed pastures can also contribute excessive amounts of sediment to local waterbodies. Excess fertilizers and pesticides can poison aquatic animals and lead to destructive algae blooms. Livestock in streams can contaminate waterways with bacteria, making them unsafe for human contact. Keep livestock away from streambanks and provide them a water source away from waterbodies. Store and apply manure away from waterbodies and in accordance with a nutrient management plan. Vegetate riparian areas along waterways. Rotate animal grazing to prevent soil erosion in fields. Apply fertilizers and pesticides according to label instructions to save money and minimize pollution. Permeable Pavement Rain Barrels Rain Gardens and Grassy Swales Vegetated Filter Strips —Traditional concrete and asphalt don’t allow water to soak into the ground. Instead these surfaces rely on storm drains to divert unwanted water. Permeable pavement systems allow rain and snowmelt to soak through, decreasing stormwater runoff. —You can collect rainwater from rooftops in mosquito- proof containers. The water can be used later on lawn or garden areas. —Specially designed areas planted with native plants can provide natural places for rainwater to collect and soak into the ground. Rain from rooftop areas or paved areas can be diverted into these areas rather than into storm drains. —Filter strips are areas of native grass or plants created along roadways or streams. They trap the pollutants stormwater picks up as it flows across driveways and streets. Residential landscaping Improperly managed logging operations can result in erosion and sedimentation. Conduct preharvest planning to prevent erosion and lower costs. Use logging methods and equipment that minimize soil disturbance. Plan and design skid trails, yard areas, and truck access roads to minimize stream crossings and avoid disturbing the forest floor. Construct stream crossings so that they minimize erosion and physical changes to streams. Expedite revegetation of cleared areas.
