Optional Additional Information or Continuation of Previous Sections As Needed 8 PRIORITY DEVELOPMENT PROJECT (PDP) REQUIREMENTS Preparation Date:________________ Template Date: August 14th, 2022 This space provided for additional information or continuation of information from previous sections as needed. PRIORITY DEVELOPMENT PROJECT (PDP) REQUIREMENTS 9 Template Date: August 14th, 2022 Preparation Date:________________ Step 2: Strategy for Meeting PDP Performance Requirements PDPs must implement BMPs to control pollutants in stormwater that may be discharged from a project (see Chapter 5). PDPs subject to hydromodification management requirements must implement flow control BMPs to manage hydromodification (see Chapter 6). Both stormwater pollutant control and flow control can be achieved within the same BMP(s). Projects triggering the 50% rule must address stormwater requirements for the entire site. Structural BMPs must be verified by the City at the completion of construction. This may include requiring the project owner or project owner's representative and engineer of record to certify construction of the structural BMPs (see Chapter 1.12). Structural BMPs must be maintained into perpetuity, and the City must confirm the maintenance (see Chapter 7). Provide a narrative description of the general strategy for pollutant control and flow control at the project site in the box below. This information must describe how the steps for selecting and designing stormwater pollutant control BMPs presented in Chapter 5.1 of the BMP Design Manual were followed, and the results (type of BMPs selected). For projects requiring flow control BMPs, indicate whether pollutant control and flow control BMPs are integrated or separate. At the end of this discussion, provide a summary of all the BMPs within the project including the type and number. 10 PRIORITY DEVELOPMENT PROJECT (PDP) REQUIREMENTS Preparation Date:________________ Template Date: August 14th, 2022 Describe the general strategy for BMP implementation at the site. The proposed project is a Storage Building. approximately 89% (48,971 sq.ft) of the site area will be impervious which includes paved driveway areas, parking and building area. Approximately 11% (5,959 sq.ft) of the site is pervious area with landscape. Proposed site is divided into two subareas i.e. DA1.1 and DA1.2 and they have their separate discharge locations, Onsite runoff from DA1.1 discharge location is at north-east of the site and for DA1.2 discharge location is at south-east side of the site. The runoff from building and roof flows away from the buildings into the ribbon gutter and curb and gutter system. Due to infeasibility in infiltration of soil, on site BioPod Biofilter system will be provided for water quality treatment in DA1.1. The runoff will flow away from the buildings and get intercepted at catch basin with insert filter. The filtered runoff will discharge into the underground pipe storage system. The excess flow from the BioPod Biofilter system will discharge into the east side of the site. Due to infeasibility to accommodate BMP system, DA1.2 will not have BioPod Biofilter system. Most of the flow from DA1.2 will discharge on to the southeast side into a pervious area for self- retaining.

The map unit descriptions in this report, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named, soils that are similar to the named components, and some minor components that differ in use and management from the major soils. Most of the soils similar to the major components have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Some minor components, however, have properties and behavior characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Map Unit Description: Ramona and Buren loams, 5 to 25 percent slopes, severely eroded--- Western Riverside Area, California Natural Resources Conservation Service Web Soil Survey National Cooperative Soil Survey 3/4/2024 Page 1 of 4 Soils that have profiles that are almost alike make up a soil series. All the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of a given series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. Additional information about the map units described in this report is available in other soil reports, which give properties of the soils and the limitations, capabilities, and potentials for many uses. Also, the narratives that accompany the soil reports define some of the properties included in the map unit descriptions.

The fact sheet does not describe design criteria like the other fact sheets in this appendix because this information varies by BMP product model. A proprietary BMP may be acceptable as a “biofiltration BMP” under the following conditions: (1) The BMP meets the minimum design criteria listed in Appendix F, including the pollutant treatment performance standard in Appendix F.1; (2) The BMP is designed and maintained in a manner consistent with its performance certifications (See explanation in Appendix F.2); and (3) The BMP is acceptable at the discretion of the City Engineer. In determining the acceptability of a BMP, the City Engineer should consider, as applicable, (a) the data submitted; (b) representativeness of the data submitted; (c) consistency of the BMP performance claims with pollutant control objectives; certainty of the BMP performance claims; (d) for projects within the public right of way and/or public projects: maintenance requirements, cost of maintenance activities, relevant previous local experience with operation and maintenance of the BMP type, ability to continue to operate the system in event that the vending company is no longer operating as a business; and (e) other relevant factors. If a proposed BMP is not accepted by the City Engineer, a written explanation/reason will be provided to the applicant. Proprietary biofiltration BMPs must meet the same sizing guidance as non-proprietary BMPs. Sizing is typically based on capturing and treating 1.50 times the DCV not reliably retain ed. Guidance for sizing biofiltration BMPs to comply with requirements of this manual is provided in Appendix F.2. Refer to manufacturer for maintenance information.

Modular Wetlands® System Linear A Stormwater Biofiltration Solution A Forterra Company 85% 64% REMOVAL OF TOTAL PHOSPHORUS REMOVAL OF TSS 45%67 % REMOVAL OF ORTHO PHOSPHORUS REMOVAL OF NITROGEN 66% REMOVAL OF DISSOLVED ZINC 38% REMOVAL OF DISSOLVED COPPER 69 % REMOVAL OF TOTAL ZINC 50% REMOVAL OF TOTAL COPPER 95% REMOVAL OF MOTOR OIL OVERVIEW The Bio Clean Modular Wetlands® System Linear represents a pioneering breakthrough in stormwater technology as the only biofiltration system to utilize patented horizontal flow, allowing for a smaller footprint, higher treatment capacity, and a wide range of versatility. While most biofilters use little or no pretreatment, the Modular Wetlands® incorporates an advanced pretreatment chamber that includes separation and pre-filter cartridges. In this chamber, sediment and hydrocarbons are removed from runoff before entering the biofiltration chamber, reducing maintenance costs and improving performance. Horizontal flow also gives the system the unique ability to adapt to the environment through a variety of configurations, bypass orientations, and diversion applications. The Urban Impact For hundreds of years, natural wetlands surrounding our shores have played an integral role as nature’s stormwater treatment system. But as cities grow and develop, our environment’s natural filtration systems are blanketed with impervious roads, rooftops, and parking lots. Bio Clean understands this loss and has spent years re-establishing nature’s presence in urban areas, and rejuvenating waterways with the Modular Wetlands® System Linear. APPROVALS The Modular Wetlands® System Linear has successfully met years of challenging technical reviews and testing from some of the most prestigious and demanding agencies in the nation and perhaps the world. Here is a list of some of the most high-profile approvals, certifications, and verifications from around the country. VA Washington State Department of Ecology TAPE Approved The MWS Linear is approved for General Use Level Designation (GULD) for Basic, Enhanced, and Phosphorus treatment at 1 gpm/ft2 loading rate. The highest performing BMP on the market for all main pollutant categories. California Water Resources Control Board, Full Capture Certification The Modular Wetlands® System is the first biofiltration system to receive certification as a full capture trash treatment control device. Virginia Department of Environmental Quality, Assignment The Virginia Department of Environmental Quality assigned the MWS Linear the highest phosphorus removal rating for manufactured treatment devices to meet the new Virginia Stormwater Management Program (VSMP) regulation technical criteria. Maryland Department of the Environment, Approved ESD Granted Environmental Site Design (ESD) status for new construction, redevelopment, and retrofitting when designed in accordance with the design manual. MASTEP Evaluation The University of Massachusetts at Amherst – Water Resources Research Center issued a technical evaluation report noting removal rates up to 84% TSS, 70% total phosphorus, 68.5% total zinc, and more. Rhode Island Department of Environmental Management, Approved BMP Approved as an authorized BMP and noted to achieve the following minimum removal efficiencies: 85% TSS, 60% pathogens, 30% total phosphorus, and 30% total nitrogen. ADVANTAGES • FLOW CONTROL • NO DEPRESSED PLANTER AREA • AUTO DRAINDOWN MEANS NO MOSQUITO VECTOR • HORIZONTAL FLOW BIOFILTRATION • GREATER FILTER SURFACE AREA • PRETREATMENT CHAMBER • PATENTED PERIMETER VOID AREA PERFORMANCE The Modular Wetlands® continues to outperform other treatment methods with superior pollutant removal for TSS, heavy metals, nutrients, hydrocarbons, and bacteria. Since 2007 the Modular Wetlands® has been field tested on numerous sites across the country and is proven to effectively remove pollutants through a combination of physical, chemical, and biological filtration processes. In fact, the Modular Wetlands® harnesses some of the same biological processes found in natural wetlands in order to collect, transform, and remove even the most harmful pollutants. CA OPERATION The Modular Wetlands® System Linear is the most efficient and versatile biofiltration system on the market, and it is the only system with horizontal flow which: • Improves performance • Reduces footprint • Minimizes maintenance Figure 1 & Figure 2 illustrate the invaluable benefits of horizontal flow and the multiple treatment stages. Cartridge Housing Pre-filter Cartridge Curb Inlet Figure 1Individual Media Filters HORIZONTAL FLOW • Less clogging than downward flow biofilters • Water flow is subsurface • Improves biological filtration PATENTED PERIMETER VOID AREA • Vertically extends void area between the walls and the WetlandMEDIA™ on all four sides • Maximizes surface area of the media for higher treatment capacity WETLANDMEDIA • Contains no organics and removes phosphorus • Greater surface area and 48% void space • Maximum evapotranspiration • High ion exchange capacity and lightweight FLOW CONTROL • Orifice plate controls flow of water through WetlandMEDIA™ to a level lower than the media’s capacity • Extends the life of the media and improves performance DRAINDOWN FILTER • The draindown is an optional feature that completely drains the pretreatment chamber • Water that drains from the pretreatment chamber between storm events will be treated 2x to 3x more surface area than traditional downward flow bioretention systems.Figure 2, Top View SEPARATION • Trash, sediment, and debris are separated before entering the pre-filter cartridges • Designed for easy maintenance access PRE-FILTER CARTRIDGES • Over 25 sq. ft. of surface area per cartridge • Utilizes BioMediaGREEN™ filter material • Removes over 80% of TSS and 90% of hydrocarbons • Prevents pollutants that cause clogging from migrating to the biofiltration chamber 2 DISCHARGE3 BIOFILTRATION2PRETREATMENT1 PERIMETER V O I D A R E A Flow Control RiserDraindown Line Outlet Pipe Vertical Underdrain Manifold BioMediaGREEN™ WetlandMEDIA™ 1 3 CONFIGURATIONS The Modular Wetlands® System Linear is the preferred biofiltration system of civil engineers across the country due to its versatile design. This highly versatile system has available “pipe-in” options on most models, along with built-in curb or grated inlets for simple integration into your storm drain design. CURB TYPE The Curb Type configuration accepts sheet flow through a curb opening and is commonly used along roadways and parking lots. It can be used in sump or flow-by conditions. Length of curb opening varies based on model and size. GRATE TYPE The Grate Type configuration offers the same features and benefits as the Curb Type but with a grated/drop inlet above the systems pretreatment chamber. It has the added benefit of allowing pedestrian access over the inlet. ADA-compliant grates are available to assure easy and safe access. The Grate Type can also be used in scenarios where runoff needs to be intercepted on both sides of landscape islands. DOWNSPOUT TYPE The Downspout Type is a variation of the Vault Type and is designed to accept a vertical downspout pipe from rooftop and podium areas. Some models have the option of utilizing an internal bypass, simplifying the overall design. The system can be installed as a raised planter, and the exterior can be stuccoed or covered with other finishes to match the look of adjacent buildings. VAULT TYPE The system’s patented horizontal flow biofilter is able to accept inflow pipes directly into the pretreatment chamber, meaning the Modular Wetlands® can be used in end-of-the-line installations. This greatly improves feasibility over typical decentralized designs that are required with other biofiltration/ bioretention systems. Another benefit of the “pipe-in” design is the ability to install the system downstream of underground detention systems to meet water quality volume requirements. ORIENTATIONS INTERNAL BYPASS WEIR (SIDE-BY-SIDE ONLY) The Side-By-Side orientation places the pretreatment and discharge chambers adjacent to one another allowing for integration of internal bypass. The wall between these chambers can act as a bypass weir when flows exceed the system’s treatment capacity, thus allowing bypass from the pretreatment chamber directly to the discharge chamber. EXTERNAL DIVERSION WEIR STRUCTURE This traditional offline diversion method can be used with the Modular Wetlands® in scenarios where runoff is being piped to the system. These simple and effective structures are generally configured with two outflow pipes. The first is a smaller pipe on the upstream side of the diversion weir - to divert low flows over to the Modular Wetlands® for treatment. The second is the main pipe that receives water once the system has exceeded treatment capacity and water flows over the weir. FLOW-BY-DESIGN This method is one in which the system is placed just upstream of a standard curb or grate inlet to intercept the first flush. Higher flows simply pass by the Modular Wetlands® and into the standard inlet downstream. END-TO-END The End-To-End orientation places the pretreatment and discharge chambers on opposite ends of the biofiltration chamber, therefore minimizing the width of the system to 5 ft. (outside dimension). This orientation is perfect for linear projects and street retrofits where existing utilities and sidewalks limit the amount of space available for installation. One limitation of this orientation is that bypass must be external. SIDE-BY-SIDE The Side-By-Side orientation places the pretreatment and discharge chamber adjacent to one another with the biofiltration chamber running parallel on either side. This minimizes the system length, providing a highly compact footprint. It has been proven useful in situations such as streets with directly adjacent sidewalks, as half of the system can be placed under that sidewalk. This orientation also offers internal bypass options as discussed below. DVERT LOW FLOW DIVERSION This simple yet innovative diversion trough can be installed in existing or new curb and grate inlets to divert the first flush to the Modular Wetlands® via pipe. It works similar to a rain gutter and is installed just below the opening into the inlet. It captures the low flows and channels them over to a connecting pipe exiting out the wall of the inlet and leading to the MWS Linear. The DVERT is perfect for retrofit and green street applications that allow the Modular Wetlands® to be installed anywhere space is available.

No other biofilter has the ability to be placed downstream of detention ponds, extended dry detention basins, underground storage systems and permeable paver reservoirs. The systems horizontal flow configuration and built-in orifice control allows it to be installed with just 6” of fall between inlet and outlet pipe for a simple connection to projects with shallow downstream tie- in points. In the example above, the Modular Wetlands® is installed downstream of underground box culvert storage. Designed for the water quality volume, the Modular Wetlands® will treat and discharge the required volume within local draindown time requirements. DESIGN SUPPORT Bio Clean engineers are trained to provide you with superior support for all volume sizing configurations throughout the country. Our vast knowledge of state and local regulations allow us to quickly and efficiently size a system to maximize feasibility. Volume control and hydromodification regulations are expanding the need to decrease the cost and size of your biofiltration system. Bio Clean will help you realize these cost savings with the Modular Wetlands®, the only biofilter than can be used downstream of storage BMPs. SPECIFICATIONS FLOW-BASED DESIGNS The Modular Wetlands® System Linear can be used in stand-alone applications to meet treatment flow requirements. Since the Modular Wetlands® is the only biofiltration system that can accept inflow pipes several feet below the surface, it can be used not only in decentralized design applications but also as a large central end-of-the-line application for maximum feasibility. ADVANTAGES • BUILT-IN ORIFICE CONTROL STRUCTURE • WORKS WITH DEEP INSTALLATIONS • LOWER COST THAN FLOW-BASED DESIGN • MEETS LID REQUIREMENTS Modular Wetlands® with Arch Plastic Chambers Modular Wetlands® with Box Culvert Prestorage PLANT SELECTION Abundant plants, trees, and grasses bring value and an aesthetic benefit to any urban setting, but those in the Modular Wetlands® System Linear do even more - they increase pollutant removal. What’s not seen, but very important, is that below grade, the stormwater runoff/flow is being subjected to nature’s secret weapon: a dynamic physical, chemical, and biological process working to break down and remove non-point source pollutants. The flow rate is controlled in the Modular Wetlands®, giving the plants more contact time so that pollutants are more successfully decomposed, volatilized, and incorporated into the biomass of the Modular Wetlands’® micro/macro flora and fauna. A wide range of plants are suitable for use in the Modular Wetlands®, but selections vary by location and climate. View suitable plants by visiting biocleanenvironmental.com/plants. INSTALLATION MAINTENANCE The Modular Wetlands® is simple, easy to install, and has a space-efficient design that offers lower excavation and installation costs compared to traditional tree-box type systems. The structure of the system resembles precast catch basin or utility vaults and is installed in a similar fashion. The system is delivered fully assembled for quick installation. Generally, the structure can be unloaded and set in place in 15 minutes. Our experienced team of field technicians is available to supervise installations and provide technical support. Reduce your maintenance costs, man hours, and materials with the Modular Wetlands®. Unlike other biofiltration systems that provide no pretreatment, the Modular Wetlands® is a self-contained treatment train which incorporates simple and effective pretreatment. Maintenance requirements for the biofilter itself are almost completely eliminated, as the pretreatment chamber removes and isolates trash, sediments, and hydrocarbons. What’s left is the simple maintenance of an easily accessible pretreatment chamber that can be cleaned by hand or with a standard vac truck. Only periodic replacement of low-cost media in the pre-filter cartridges is required for long-term operation, and there is absolutely no need to replace expensive biofiltration media. INDUSTRIAL Many states enforce strict regulations for discharges from industrial sites. The Modular Wetlands® has helped various sites meet difficult EPA-mandated effluent limits for dissolved metals and other pollutants. PARKING LOTS Parking lots are designed to maximize space and the Modular Wetlands’® 4 ft. standard planter width allows for easy integration into parking lot islands and other landscape medians. MIXED USE The Modular Wetlands® can be installed as a raised planter to treat runoff from rooftops or patios, making it perfect for sustainable “live-work” spaces. RESIDENTIAL Low to high density developments can benefit from the versatile design of the Modular Wetlands®. The system can be used in both decentralized LID design and cost-effective end-of-the-line configurations. STREETS Street applications can be challenging due to limited space. The Modular Wetlands® is very adaptable, and it offers the smallest footprint to work around the constraints of existing utilities on retrofit projects. COMMERCIAL Compared to bioretention systems, the Modular Wetlands® can treat far more area in less space, meeting treatment and volume control requirements. APPLICATIONS The Modular Wetlands® System Linear has been successfully used on numerous new construction and retrofit projects. The system’s superior versatility makes it beneficial for a wide range of stormwater and waste water applications - treating rooftops, streetscapes, parking lots, and industrial sites.

In addition, loose trash and debris can be easily transported by water or wind to nearby storm drain inlets, channels, and/or creeks. Trash generating facilities that generate large amounts of trash require special attention to protect trash storage areas from rainfall, run-on, runoff, and wind dispersal. Large trash generating, or trash build-up areas, include but are not limited to restaurants, supermarkets, “big box” retail stores serving food, and pet stores. The City Engineer may designate additional facilities if they are likely to generate or accumulate large quantities of trash. Example isometric view and plan view of an allowable trash enclosure facility is presented below. The project applicant may be allowed to use an alternative trash enclosure design that might be more appropriate for a project site if the alternative design is approved by the City Engineer.

Typical Isometric and Plan View of a Trash Enclosure BMP Source control BMPs reduce the amount of pollutants that are generated. This fact sheet contains details on the additional measures required to prevent or reduce pollutants in storm water runoff associated with trash storage and handling for large trash generating facilities. The Design Adaptations for Project Goals SC-Q Large Trash Generating Facilities E-18 July 2018 requirements presented here are in addition to the requirements of SC-5 which requires all development projects to protect trash storage areas from rainfall, run-on, runoff, and wind dispersal:  Areas where trash containers are stored must be enclosed on four sides to prevent off-site transport of trash. Four-sided trash enclosures typically consist of three walled sides and one gated side. Trash enclosures limit the potential for trash to pollute storm water runoff by limiting mobilization mechanisms (runoff, run-on, and wind dispersal).  Trash enclosures must be covered to minimize direct precipitation and prevent rainfall from entering enclosures. Structural overhead covers are required as container lids are often left open.  Enclosures must be hydraulically isolated from surrounding areas. Slabs shall be sloped such that any leaked materials will be contained within the enclosure. Drains must be provided that capture and direct potential leaks to the sanitary sewer or appropriate BMPs. Divert runoff from surrounding areas away from the enclosure to prevent contamination and dispersion of collected materials.  Owner must provide BMP storm water training to employees. Employee participation is required to ensure that enclosures are properly maintained and kept clean. All trash shall be stored in weather-protected receptacles/bins and recyclable materials shall be protected against adverse weather conditions, which might render the collected materials unmarketable. Trash enclosure dimensions will vary based on projected usage and the following information is offered as an aid in planning new projects. Businesses that use dumpsters must design the enclosure to accommodate three-yard containers at a minimum. The tenants may use any dumpster size that is appropriate for their needs, but the enclosure must be able to accommodate different tenants with varying waste production, including any recycling requirements. The design of the enclosure must be signed and sealed by a California licen sed engineer. Substantiating structural calculations may be required. The location and design of the enclosure will require review and approval by the City Engineer. Building permits may be required. The following recommendations for typical bin sizes are adopted from the City of Escondido trash enclosure guidelines. The following bin/container measurements are approximate (add 8” to width for side pockets): B.2. Typical Trash Bin Sizes Size Width Depth Height (front) Height (back) 3 cubic yard 72” bin, 81” plus lid 43” 42” 70” 4 cubic yard 72” bin, 81” plus lid 56” 72” 72” Filled weight should not exceed 1,000 pounds. 4. Enclosures shall be structurally strong and constructed of reinforced masonry block or wood panels/boards. Structural requirements for enclosures are detailed in the City of San Diego Design Criteria and Considerations SC-Q Large Trash Generating Facilities E-19 July 2018 specifications for Wood and Masonry Fences. http://www.sandiego.gov/development-services/pdf/industry/infobulletin/ib223.pdf 5. The enclosure should be constructed to the following minimum inside dimensions to accommodate three cubic-yard dumpsters (larger enclosures may be necessary to accommodate additional trash bins, recycling bins, and accessibility): No. of Bins Loading Width Depth Height One Front 8’ 6’ 6’ One Side 7.5’ 8’ 6’ Two Front 16’ 6’ 6’ Two Side 8’ 16’ 6’ 6. The enclosure slab should be designed to keep storm water drainage out of the enclosure area, typically sloped at 0.5%. Slab construction specifications will vary according to methods of construction, but should be at least 4 inches of reinforced concrete. 7. Sturdy gates/doors shall be installed on all enclosures. Gates should not be mounted directly onto the block wall or inside of enclosure. The enclosure should include hardware to secure the gate’s doors both open and closed (i.e., cane bolt w/sleeve and latch between doors and sleeve in pavement). 8. To prevent trash enclosures from contributing to storm water runoff pollution, all enclosures must be fitted with a roof deigned to drain into on-site landscape areas (where necessary) and/or to appropriate BMPs. The roof must provide sufficient clearance to allow the dumpster lid to open to the 90 degree position. 9. Enclosure roofs not conforming to City specifications for Patio Covers may require a building permit. Generally roofs not more than 12 feet in height above grade and constructed with conventional light-frame wood construction are considered acceptable. The use of metal roofs is not recommended as they can act as a source of pollutants. http://www.sandiego.gov/development-services/pdf/industry/infobulletin/ib206.pdf 10. Dumpsters associated with food establishments shall be sized per Riverside County Health Department requirements for wash down. Drains shall be connected to the business grease interceptor.
