The project is located east of Interstate 5, south of Haymar Drive, and west of College Boulevard in the City of Carlsbad, and borders the City of Oceanside. See the Vicinity Map at the end of Section 1.0 for the location of the project. The project proposes to prepare previously mass graded pads from a previous quarry reclamation project (DWG 470-5A) into developable pads zoned for residential units consisting of medium and high density housing, public use areas including a park and ride, a community facility site and nature education center, and park and open space areas. The first phase of the project includes grading the pads, construction of the major public roads and utilities, and grading of the Low Impact Development (LID) facilities associated with construction of the major roads. This SWMP addresses post construction storm water management based on the land use zoning, however several of the lots will ultimately be sold to future developers and it v^ll be the responsibility of the future developers to prepare site specific SWMPs. Even though this SWMP accounts for all of the treatment and hydromodification on a regional scale for the entire development, fiiture developers may need to prepare SWMP addendums or separate SWMPs to address the site and source control BMPs proposed with their individual developments, and to document that their individual site plans are consistent with the design assumptions for the regional BMPs used in this overall SWMP. For the purposes of post-construction storm water quality management, the project will follow the guidelines and requirements set forth in the City of Carlsbad's "Standard Urban Storm Water Management Plan (SUSMP)," adopted January 14, 2011 (herein "SUSMP"). A copy ofthe City of Carlsbad Storm Water Standards Questiormaire (SWSQ) for the project is located in Appendix A of P:\2468.20\Engt\Reports\WQTR-FE\2468.20 WQTR FE.doc 1 this SWMP. Based on the SWSQ, this project meets the requirements for a "Priority Development Project." The following Priority Development Project categories apply to the project: "Housing subdivisions of 10 or more dwelling units," "Hillside Developmenf, "Commercial - greater than 1- acre", "Environmentally Sensitive Area (ESA)", "Parking lot", "Streets, roads, highways, and freeways," and "More than 1-acre of disturbance." In accordance with the Municipal Permit and final Hydromodification Management Plan (HMP) dated March 2011, Section 2 of the SUSMP states that projects subject to Priority Development Project requirements might be required to implement measures so that post-development runoff rates and durations do not exceed pre-project conditions (hydromodification controls). The Municipal Permit (Califomia Regional Water Quality Control Board, San Diego Region, Order No. R9-2007-0001) is the permit that governs stormwater requirements for development projects. As a condition of the Municipal Permit, the City is required to enforce the Hydromodification Management Plan requirements for all priority projects. According to Figure 2-1 in the SUSMP, (HMP AppHcability Determination Matrix), the Quarry Creek project is subject to the final HMP. A copy of the HMP Applicability Determination Matrix is located in Appendix B. Therefore, a hydromodification management strategy has been developed for the project and is discussed in more detail in Section 5.0 of this report. The hydromodification management strategy was developed for onsite flows, as offsite flows are not subject to hydromodification management requirements. In the pre-project condition, storm water runoff from the site discharges to a tributary of Buena Vista Creek as well as directly to Buena Vista Creek and flows westerly to Buena Vista Lagoon and ultimately discharges to the Pacific Ocean. The proposed project will maintain drainage patterns similar to the pre-project condition hydrologic characteristics, therefore storm water runoff trom the P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 2 proposed site will discharge to Buena Vista Creek and flow westerly to Buena Vista Lagoon and ultimately discharge to the Pacific Ocean. For the purposes of the SWMP the project is defined by five major drainage basins and corresponding Points of Compliance (POC). Runoff fi-om four of the drainage basins flows to Buena Vista Creek. Runoff from the fifl;h drainage basin flows to a tributary of Buena Vista Creek and confluences with Buena Vista Creek downstream of the project. Buena Vista Creek travels in a westerly direction to Buena Vista Lagoon and ultimately discharges to the Pacific Ocean. The following provides a description of the drainage characteristics for the pre-project and post- project conditions. 1.1 Pre-Project Condition For the purposes of this SWMP, the pre-project condition is based on the site topography created from aerial photogrammetry by Project Design Consultants dated September 2006. The Mimicipal Permit requires Priority Development Projects to manage increases in ranoff discharge rates and durations which are likely to cause erosion, sediment pollutant generation, or other impacts to beneficial uses and stream habitat. Historically, the channels to which the project discharges have been responding to the natural watershed characteristics that existed prior to the site being mass graded. The mass graded condition (Hanson Reclamation Condition per Drawing 470-5A) is a manufactured condition which does not accurately represent the watershed that formed the downstream channels. In order to comply with the intent of the Municipal Permit, the post-project condition should be compared to the natural watershed characteristics to which the receiving channels have been receiving runoff over the long-term historical range of flow rates, not the very recent condition of the mass-graded flat pad. Therefore, in this case it is more appropriate to use the P;\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc historical topography for the pre-project hydromodification analysis as opposed to the mass graded condition (Hanson Reclamation Condition) topography. Please refer to the Pre-Project Slope Analysis and Land Cover exhibit in Appendix E. POC-1 Basin 1 consists of the northeastem portion of the project which drains in a southerly direction to Buena Vista Creek. Refer to the exhibits in Appendix E for the location of each drainage basin and Point of Compliance. The drainage basins are labeled according to the POC to which it discharges. Basin 1 discharges to POC 1. Land uses in the basin are comprised of a defunct mining site which currently consists of undeveloped areas of dirt and grass. There is an existing 54-inch storm drain that conveys offsite flows through Basin 1. The existing storm drain currently includes a low-flow diversion structure on the north side of the pad that diverts low flows within the pipe to a swale, which provides a minor amount of water quality treatment for runoff fi-om an offsite drainage area located north of the project. Flow from the downstream end of the swale gets collected back into the existing 54-inch pipe. Refer to Sheet 9 of Drawing 470-5A for the low-flow pipe diversion structure. POC-3-2 Basin 3-2 consists of the northwestern portion of the project which drains in a southerly direction to Buena Vista Creek. Basin 3-2 discharges to POC 3-2. Land uses in the basin are comprised of a defunct mining site which currently consists of undeveloped areas of dirt and grass. P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc POC-3-3 & POC-3-7 Basin 3-3 is in the northerly section of the southeastem portion of the project. Basin 3-3 drains in a northerly direction to Buena Vista Creek. Basin 3-3 discharges to POC 3-3. Land uses in the basin are comprised of a defunct mining site which currently consists of undeveloped areas of dirt and grass. There is an existing 60-inch storm drain that conveys offsite low-flows through Basin 3-3. The existing storm drain currently includes a low-flow diversion structure on the south side of the pad that diverts low flows within the pipe to a swale, which provides a minor amount of water quality treatment for mnoff from an offsite drainage area located southeast of the project. Flow from the downstream end of the swale gets collected back into the existing 60-inch pipe. Refer to Sheet 10 of Drawing 470-5A for the low-flow pipe diversion stmcture. Basin 3-7 is in the southerly section of the southeastem portion of the project which drains in a northerly direction to Buena Vista Creek. Basin 3-7 discharges to the same outfall to the creek as POC 3-3, therefore the POC is labeled POC 3-3/3-7. Land uses in the basin are comprised of a defunct mining site which currently consists of undeveloped areas of dirt and grass. POC-4 Basin 4 is in the southem central portion of the project which drains in a northerly direction to Buena Vista Creek. Basin 4 discharges to POC 4. Land uses in the basin are comprised of imdeveloped areas of dirt and grass. POC-5 Basin 5 consists of the southwest portion of the project and drains in a southerly direction to an existing natural unlined vegetated open channel that conveys flows westerly and confluences with P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc Buena Vista Creek approximately 2700 feet downstream of the project site. Basin 5 discharges to POC 5. Land uses in the basin are comprised of undeveloped areas of grass. 1.2 Post-Project Condition The first phase of the project includes grading the pads for future site development, constmction of the project circulation public roads and utilities, and implementation of the Low Impact Development (LID) facilities associated with the project. LID facilities have been sized for the ultimate build-out condition and will be constmcted as part of the first phase to ensure that the future development is treated in a regional fashion prior to offsite discharge. In the post-project condition, drainage will be conveyed through a network of storm water management features for Priority Development LID requirements, water quality treatment, and hydromodification management prior to outletting to proposed storm drain outfalls. Please refer to the Storm Water Management Plan exhibit located and the "Drainage Basins" exhibit in Appendix E for the location of each drainage basin and Point of Compliance. The drainage basins are color coded on the "Drainage Basins" exhibit and labeled according to the POC to which it discharges. POC-1 Basin 1 is located in the northeasterly area of the project and includes a small area of offsite runoff from the City of Oceanside parcel to the east in addition to mnoff from Lot 1 and part of Lot 2. Runoff will be directed to a bioretention/hydromodification basin (Basin-1) which outlets to POC 1. The tributary area to Basin 1 is approximately 13.7 acres. Land uses in the basin are comprised of high density residential and streets. P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc POC-3-2 Basin #3-2-a and Basin #3-2-b are also located in the northeasterly area of the project and include runoff from portions of Lot 2, Lot 5, Lot 6, Lot 11, Haymar Drive, and El Salto Fall Street. Runoff will be directed to bioretention/hydromodification basins (Basin-3-2-a & Basin-3-2-b) which outlet to POC 3-2. The tributary area to Basin 3-2a is approximately 8.7 acres and the tributary area to Basin 3-2b is approximately 5.2 acres. Land uses in the basin are comprised of a park, high density residential, and streets. POC-3-3 & POC-3-7 Basin 3-3 is located in the northerly section of the southeastem area of the project and includes mnoff from Lot 3. Runoff will be directed to a bioretention/hydromodification basin (Basin 3-3) located northwest of the intersection of Marron Street and Adobe Springs Road which outiets to POC 3-3/3-7. Basin 3-3 is approximately 7.5 acres. Land uses in the basin are comprised of medium-high residential. Basin 3-7 is located in the southerly section of the southeastem area of the project and includes runoff from Lot 7. Runoff will be directed to a bioretention/hydromodification basin basin located within Lot 7 which outlets to POC 3-3/3-7. Basin 3-7 is approximately 3.7 acres. Land use in the basin is comprised of a community facility site. POC-4 Basin 4 is located in the southem central area of the project and includes mnoff from the eastem portion of Lot 4, Lot 8, Lot 9, portions of Marron Road, and portions of Adobe Springs Road. Runoff will be directed to a bioretention/hydromodification basin (Basin-4) which outlets to POC 4. P:\2468.20\Engr\Rfiports\WQTR-FE\2468.20 WQTR FE.doc The tributary area to Basin 4 is approximately 24.6 acres. Land uses in the basin are comprised of medium-high residential and public use trails and parks and streets. POC-5 Basin 5 is located in the southwest area of the project and includes runoff from the westem portion of Lot 4, Lot 10, and portions of Marron Road. Runoff will be directed to a bioretention/hydromodification basin (Basin-5) which outlets to POC 5. The tributary area to Basin 5 is approximately 7.7 acres. Land uses in the basin are comprised of medium-high residential and streets and a small parking lot. In the post-project condition, peak flow and duration controls will be provided so as not to exceed pre-project peak flows and durations as required by the Final HMP. There will be a number of storm water management features working to provide peak flow rate and duration controls, as discussed in Section 5.0. Calculations for the final storage volumes needed for hydromodification and water quality treatment for each drainage basin are provided in Attachment D. Constraints and opportunities for site design and selection of treatment and flow-control facilities have been identified for the project. The majority of the project consists of type D soil which presents a constraint in the selection of integrated management practices (IMPs). Opportunities include utilizing the 50-foot wide building setback and 100-foot wide vegetated buffer zone, non- contiguous sidewalks, open space areas and parks, and incorporating landscape/vegetated areas in the common public use areas of the project. The 50 and 100-foot wide buffer zones present an opportunity as they provide adequate area for the detention facilities while optimizing the site layout. P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc An integrated LID approach will be utilized to provide a long-term solution to water quality at the project site. This SWMP is also intended to ensure the effectiveness of the BMPs or IMPs through proper maintenance that is based on long-term fiscal planning. Please refer to the DMA/IMP/BMP exhibit located in Appendix E of this report for locations of the drainage facilities and storm water LID facilities, including tributary drainage areas and flow pattems for the site. 1.3 Offsite Runoff Treatment This project proposes to utilize two (2) Bio Clean Water Polisfter Up Flow Media Filters to provide water quality treatment for low-flow stormwater mnoff from the two offsite basins that are currently being treated via the swales and low-flow diversion structures discussed previously in this report. The project v^U continue to provide water quality treatment from two existing low-flow storm drain systems. Details and specifications are located in Appendix C. Per the water quality treatment calculations performed by Chang Consultants, the water quality treatment flow rate is 0.89 cubic feet per second (cfs) discharging to POC-1 from an offsite drainage area north of the project, and 0.63 cubic feet per second (cfs) discharging to POC-3 from an offsite drainage area located southeast of the project (from the existing shopping center). Refer to Chang's Drainage Report for South Coast Materials Quarry, dated May 26, 2011. Since these flows are offsite flows, hydromodification requirements for these flows do not apply.

The procedure begins by identifying pollutants typically associated with specific types of project/use. Receiving waters are classified by watershed and hydrologic unit basin number and then checked for impairments per the latest Clean Water Act Section 303(d) list. Any pollutants that are both anticipated project pollutants and listed as impairments are categorized as primary pollutants of concem. 2.1 Identify Pollutants from the Project Area Table 2-1 of the SUSMP, "Anticipated and Potential Pollutants Generated by Land Use Type" identifies general pollutant categories associated with priority development projects. The following priority project categories listed in Table 2-1 apply to this project: "Housing subdivisions of 10 or more dwelling units," "Hillside Development", "Commercial - greater than 1-acre", "Environmentally Sensitive Area (ESA)", "Parking lot", "Streets, roads, highways, and freeways," and "More than 1-acre of disturbance." These categories shall be used to determine the anticipated or potential pollutants for the project. Table 2-1 of the SUSMP is reproduced on the following page, with the Priority Development Project categories applicable to the project highlighted. P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 11 TABLE 2-1.

P:\2468.20\i'.ngr\Reporis\WQTR-FE\2468.20 WQTR FE.doc 12 Based on the highlighted rows, the anticipated pollutants from the project include sediments, nutrients, heavy metals, organic compounds, frash & debris, oxygen demanding substances, oil and grease, bacteria and virases, and pesticides. 2.2 Identify Pollutants of Concern in Receiving Waters To identify pollutants of concem in receiving waters, the following procedure was followed: (1) for each of the proposed project discharge points, identify the receiving water(s), hydrologic unit basin number(s) as identified in the most recent version of the "Water Quality Control Plan for the San Diego Basin," prepared by the San Diego Regional Water Quality Control Board (SDRWQCB); and (2) identify any receiving waters, into which the developed area would discharge to, included in the "2010 CWA Section 303(d) List of Water Quality Limited Segments," as approved by the State Water Quality Control Board (SWRCB). List any and all pollutants for which the receiving waters are impaired. Identification of Receiving Waters According to the "Water Quality Control Plan for the San Diego Basin," (Basin Plan) dated September 8, 1994, prepared by the SDRWQCB, the project is located in the following hydrologic unit basin: El Salto Subarea in the Buena Vista Creek Hydrologic Area within the Carlsbad Hydrologic Unit. The corresponding hydrologic unit basin number designation is 904.21 (San Diego Region '9', Hydrologic Unit '04', Hydrologic Area '2', and Hydrologic Subarea '1'). An exhibit has been provided in Appendix E of this report titled, "Hydrologic Unit for Quarry Creek" which shows the project location within Hydrologic Unit 904.21. Project runoff discharges to Buena Vista Creek and ultimately discharges into the Pacific Ocean via the Buena Vista Lagoon. P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 13 Identification of Receiving Water Impairments According to the 2010 303(d) List, both Buena Vista Creek and Buena Vista Lagoon v^rithin HU 904 are identified as impaired water bodies. Buena Vista Creek is listed for Selenium (a heavy metal) and Sediment Toxicity and Buena Vista Lagoon is listed for Indicator Bacteria, Nutrients and Sedimentation/Siltation. Beneficial Uses of Receiving Water According to the Basin Plan, the existing beneficial uses of the Buena Vista Creek and Buena Vista Lagoon are Agricultural Supply (AGR), Industrial Service Supply (IND), Contact Water Recreation (RECl), Non-contact Water Recreation (REC2), Warm Freshwater Habitat (WARM), Wildlife Habitat (WILD), Rare, Threatened or Endangered Species (RARE). Primary Pollutants of Concem for the Proiect Based on Table 2-1 and the 303(d) List of Water Quality Limited Segments, the following are the project's primary pollutants of concem: sediments, nutrients, heavy metals, organic compounds, and bacteria and vimses. Primary pollutants of concem are those anticipated from the project that area also listed on the 303(d) list. The remaining anticipated and potential pollutants as identified in Table 2-1 are secondary pollutants of concem (trash and debris, oxygen demanding substances, oil and grease, and pesticides). The LID design approach and source control BMPs will be utilized to treat these primary and secondary pollutants of concem to the maximum extent practicable (MEP). P:\2468.20\EngrtReports\WQTR-FE\2468.20 WQTR FE.doc 14 3.0 SOURCE CONTROL BMPS The term "source control BMP" refers to land use or site plarming practices, or structures that aim to prevent urban mnoff pollution by reducing the potential for contamination at the source of pollution. Source control BMPs minimize the contact between pollutants and urban mnoff. The foUovying discussion identifies the source control BMPs for the project. TABLE 3-1. PERMANENT AND OPERATIONAL SOURCE CONTROL MEASURES Potential Source of Runoff Pollutants Permanent Source Control BMPs Operational Source Control BMPs On-site storm drain inlets Mark all inlets with the words "No Dumping! Flows to Bay" or similar Maintain and periodically repaint or replace inlet markings. Provide stormwater pollution prevention infonnation to new site owners, lessees, or operators. Maintain storm drain inlets per Fact Sheet SC-44, "Drainage System Maintenance," in the CASQA Stormwater Quality Handbooks. Include the following in lease agreements: "Tenant shall not allow anyone to discharge anything to storm drains or to store or deposit materials so as to create a potential discharge to storm drains." Interior floor drains and elevator shaft sump pumps and Interior parking garages Interior floor drains and elevator shaft sump pumps will be plumbed to sanitary sewer. Inspect and maintain drains to prevent blockages and overflow. Landscape / Outdoor Pesticide Use Final landscape plans will accomplish all of the following: Preserve existing native trees, shrubs, and ground cover to the maximum extent possible. Design landscaping to minimize irrigation and runoff, to promote surface infiltration where appropriate, and to minimize the use of fertilizers and pesticides that can contribute to stormwater pollution. Where landscaped areas are used to retain or detain stormwater, specify plants that are tolerant of saturated soil conditions. Consider using pest-resistant plants. Maintain landscaping using minimum or no pesticides. Maintain buildings and common areas per CASQA Fact Sheet SC-41, "Building and Grounds Maintenance." Provide IPM information to new owners, lessees and operators P:\2468.20\EngrtReports\WQTR-FE\2468.20 WQTR FE.doc 15 especially adjacent to hardscape. To insure successfiil establishment, select plants appropriate to site soils, slopes, climate, sun, wind, rain, land use, air movement, ecological consistency, and plant interactions. Pools, spas, ponds, decorative fountains and other water features If the local municipality requires pools to be plumbed to the sanitary sewer, place a note on the plans and state in the narrative that this connection will be made according to local requirements. Maintain water features per CASQA Fact Sheet SC-72, "Fountain and Pool Maintenance" Refiise areas During fiiture site planning, refiise areas will be designed to be screened and covered. State that signs will be posted on or near dumpsters with the words "Do not dump hazardous materials here" or similar. The following will be implemented: Provide adequate number of receptacles. Inspect receptacles regularly; repair or replace leaky receptacles. Keep . receptacles covered. Prohibit/prevent dumping of liquid or hazardous wastes. Post "no hazardous materials" signs. Inspect and pick up litter daily and clean up spills immediately. Keep spill control materials available on-site. Handle and dispose of waste per CASQA Fact Sheet SC-34, "Waste Handling and Disposal" Outdoor storage of equipment or materials Include a detailed description of materials to be stored, storage areas, and structural features to prevent pollutants fl-om entering storm drains. Where appropriate, reference documentation of compliance with the requirements of local Hazardous Materials Programs for: • Hazardous Waste Generation • Hazardous Materials Release Response and Inventory • Califomia Accidental Release (CalARP) • Aboveground Storage Tank • Uniform Fire Code Article 80 Section 103(b) &(c) 1991 • Underground Storage Tank Store outdoor equipment and materials per CASQA Fact Sheets SC-31, "Outdoor Liquid Container Storage" and CASQA SC-33, "Outdoor Storage of Raw Materials." Miscellaneous drain or wash water: Roofing, gutters, and trim Avoid roofmg, gutters, and trim made of copper or other unprotected metals that may leach into runoff. Plazas, sidewalks, and parking lots Plazas, sidewalks, and parking lots shall be swept regularly to prevent the accumulation of debris. Debris fi-om pressure washing shall be collected to prevent entry into the storm drain system. Washwater containmg any cleaning agent or degreaser shall be collected and discharged to the sanitary sewer and not discharged to a storm drain. P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 16 4.0 INTEGRATED LOW IMPACT DEVELOPMENT (LID) DESIGN STRATEGIES The following discussion addresses requirements of Section 4 of the SUSMP. As listed in the section, projects subject to Priority Development Project requirements must implement an integrated LID approach to develop and size IMPs or use the "Altematives to LID Design," which requires each stormwater objective to be separately addressed. This project will implement an integrated LID approach to meet criteria described in the SUSMP. The integrated LID approach includes preservation of natural areas, stream setbacks, features that mimic the pre-project hydrology, and use of natural BMPs for stormwater treatment. As an approach to Integrated LID design, the following sections will discuss LID strategies for managing runoff from the project. 4.1 Optimization of Site Layout The SUSMP lists preserving natural drainage facilities and minimizing impervious areas as two key components to optimizing the site layout for LID. The project is proposing to grade lots and construct utilities and roads upon previously mass graded lots. During the entitlement, the original proposed developable footprint was reduced, thereby achieving both a reduction in impervious areas and preserving the westerly part of the project as open space. The project also includes a significant portion of open space preservation throughout the site. The project is conditioned to provide a 50- foot building setback as well as a 100-foot vegetated buffer area in between the development and Buena Vista Creek. Therefore, the project is building upon less sensitive areas of the site and is minimizing disturbance of natural areas. The vegetated buffer will also provide an area where drainage can be used as a design element to incorporate the proposed IMP facilities. P:\2468.20\Engi\Reports\WQTR-FE\2468.20 WQTR FE.doc 17 Wherever feasible, landscape and vegetated areas will be utilized to minimize directly connected impervious areas. In order to maximize canopy interception and water conservation, the project will provide native or drought tolerant vegetation for proposed landscape areas and include trees for canopy interception. 4.2 Use of Pervious Surfaces The project includes a network of decomposed granite (DG) trails in order to utilize pervious surfaces for retention of mnoff Where feasible, future development of the lots within the project will incorporate pervious surfaces throughout the project in accordance with City of Carlsbad requirements. 4.3 Dispersal of Runoff to Pervious Areas The project includes non-contiguous sidewalks in order to disperse runoff from impervious areas onto adjacent pervious surfaces. Where feasible, the project site shall incorporate some landscaping areas on the site that collect runoff from impervious surfaces prior to collection into the storm drain system. During future site planning, some sidewalks and walkways may be designed as non- contiguous within the future lots, thereby allowing sidewalk mnoff to flow across vegetated areas prior to conveyance within the street. 4.4 Use of Integrated Management Practices The term "Integrated Management Practice" (IMP) refers to a facility that provides small-scale treatment, retention, and/or detention and is integrated into site layout, landscaping, and drainage design. The following tables from the City's SUSMP have been evaluated to determine appropriate P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 18 IMPs for treatment of runoff potentially containing most pollutants of concem. Tables 2-2 and 2-3 from the SUSMP are renamed as Tables 4-1 and 4-2 and are reproduced below. TABLE 4-1.

Groups of Pollutants and Relative Effectiveness of Treatment Facilities." City of Carlsbad Standard Urban Stormwater Mitigation Plan, January 2011, pg. 25 Six Bioretention/Hydromodification Detention Facilities are proposed for treatment of onsite runoff from the Quarry Creek project. However, offsite low-flows from two adjacent development areas are proposed to be treated using high-rate media filters. Tables 4-1 and 4-2 show that the suite of BMPs selected for this project address all of the primary and secondary pollutants of concem. The bioretention facilities, although not designed for retention, will provide treatment of the stormwater water quality volume and associated pollutants. Full retention (infiltration BMPs) were not selected for the project due to geotechnical constraints. The following IMPs are considered appropriate for treatment of the pollutants of concem: P:\2468.20\i:ngr\Repons\WQ rR-FE\2468.20 WQTR FE.doc 20 • Bioretention facilities, which can be configured as swales, free-form areas, or planters to integrate with the landscape design - SELECTED • Dry wells, which can be used only where soils are permeable - Not Selected • Cisterns, in combination with a bioretention facility - Not Selected In order to determine the most appropriate IMP (or combination thereof) for the project, several design altematives were considered, including locating bioretention areas within the parkway for the street and utilizing pervious pavement within the street and for the Park and Ride. The necessary areas required to treat the mnoff from the project made utilizing the parkway for bioretention difficult to achieve. The most practical location for the detention basins is within the 50-foot building setback and 100-foot vegetated buffer areas previously discussed. These areas provide adequate space and optimize the project site layout. Therefore locating the bioretention basins in these areas best utilizes the area within the site plan for the project. Refer to Appendices C and D for the BMP calculations. P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 21 5.0 HYDROMODIFICATION In accordance with the Municipal Permit and final hydromodification management plan (HMP) dated March 2011, Section 2 of the SUSMP states that projects subject to Priority Development Project requirements might be required to implement measures so that post-development runoff rates and durations do not exceed pre-project conditions (hydromodification controls). The following methods may be used to meet HMP mitigation requirements: Design BMPs pursuant to standard sizing and specification criteria detailed in the SUSMP and the HMP/LID Sizing Calculator using the automated sizing spreadsheet (San Diego BMP Sizing Spreadsheet), use a continuous simulation model to compare pre-project and mitigated post-project runoff and durations until compliance to flow control standards can be demonstrated, or identify a specified exemption defined in the SUSMP and final HMP. According to Figure 2-1, HMP Applicability Determination Matrix, in the SUSMP, the Quarry Creek project is subject to the final HMP requirements. Therefore, a hydromodification management strategy has been developed for the project. The project will use a network of storm water management features that have been sized based on IMP and BMP sizing approach for hydromodification management. The continuous simulation model, the San Diego Hydrology Model (SDHM) from Clear Creek Solutions, was used to compare pre-project and mitigated post- project runoff and durations to comply with flow control standards as defined in the final HMP. 5.1 Modeling Methodology The final HMP requires a range of runoff flow rates and durations to be compared in order to demonstrate using a continuous simulation modeling approach that the post-project ranoff flows and durations shall not exceed pre-project ranoff flows and durations for the threshold limits P;\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 22 identified in the permit. The modeling results must show compliance with the following criteria: for flow rates between the pre-project lower flow threshold and the pre-project 10-year event, the post-project discharge rates and durations may not deviate above the pre-project rates and durations by more than 10% over more than 10% of the length of the flow duration curve. • Lower flow thresholds may be determined using the HMP Decision Matrix along with a critical flow calculator and channel screening tools developed by the Southem Califomia Coastal Water research Project (SCCWRP). These methods identify lower flow thresholds for a range of channel conditions. The critical flow calculator recommends a lower flow value of 0.1Q2, 0.3Q2, or 0.5Q2 dependent on the receiving channel material and dimensions. This value will be compared to the channel susceptibility rating (High, Medium, or Low) as determined from the SCCWRP screening tools to determine the final lower flow threshold. • The lower flow threshold may alternately be determined as 10 percent of the pre-project 2year runoff event, or 0.1 Q2. This approach, which is outlined in the HMP Decision Matrix, is available if the project applicant chooses not to complete the channel screening analysis. • The flow duration frequency analysis is performed on the range of flows from the lower flow threshold to the upper flow threshold. The upper flow threshold is the pre-project QIO value. The continuous simulation modeling used to analyze this project for compliance with the Final Hydromodification Management Criteria was performed using the San Diego Hydrology Model (SDHM) from Clear Creek Solutions. The release date for the version of SDHM utilized for the project is April 5, 2013. The software is capable of modeling hydromodification management (flow P;\2468.20\EngrVReports\WQTR-FE\2468.2O WQTR FE.doc 23 control) facilities to mitigate the effects of increased runoff from the post-project land use changes that may cause negative impacts (i.e. erosion) to dovmstream channels. The SDHM continuous simulation model uses local rainfall data to estimate flows over a unit time step for a given period. The rainfall gauge location selected for this project was the Oceanside gauge, which represents the project appropriately based on isopluvial and precipitation zone characteristics and has hourly data for the period of record of 1949 to 2007. Continuous simulation programs account for all storm events, which differ from typical methods of determining the peak flow from a single storm event (i.e. 100-year). SDHM uses the Hydrologic Simulation Program Fortran (HSPF) software as its computational engine to run rainfall-ranoff algorithms. Partial Duration Flow Frequency Determination The peak flow frequency statistics (i.e. Q2 and QIO) estimates how often flow rates will exceed a given threshold. There are two common methods to determine the frequency of recurrence of flood data: annual maximum series or partial duration series. The annual maximum series selects the highest peak discharge in one year. The partial duration series considers multiple storm events in a given year. According to the Final HMP, the need for partial duration statistics is more pronounced for control standards based on more frequent retum intervals (such as the 2-year ranoff event) since the peak aimual series does not perform as well in the estimation of such events. The use of a partial duration series is also recommended for semi-arid climates similar to San Diego County, where prolonged dry periods can skew peak flow frequency results determined by a peak annual series for more frequent runoff events. The partial duration series provides better resolution for assigning recurrence intervals to events that occur more frequently than once per 10 years, which are the most P:\2468.20\Engr\Repoits\WQTR-FE\2468.20 WQTR FE.doc 24 important events for the HMP. SDHM defaults to compute peak flow frequency statistics by constructing a partial duration series. For the statistical analysis of the rainfall record, partial duration series events have been separated into discrete rainfall events based on the following criteria: • A discrete rainfall event occurs when a lower flow limit equal to 0.002 cfs per acre of contributing drainage area is calculated by the model. • The discrete event ends when the flow falls below 0.002 cfs per acre for a time period of 24 hours or more. Land Cover and Slope Analysis The input values for the SDHM model were developed by breaking the drainage area to each POC into discrete drainage management areas (DMAs). Since the project area drains to various discharge locations, multiple POCs and therefore multiple SDHM models are required. The areas draining to each basin were separated into discrete areas with uniform cover properties for modeling purposes within SDHM. All pervious areas were modeled with grass cover. All pervious areas were categorized into slope categories of flat (0-5%), moderate (5-10%), or steep (greater than 10%). For the pre-project condition, a slope analysis was performed on the pre-project topography using GIS to separate the drainage areas into the various slope categories. For the post-project condition, the land cover analysis was performed on the post-project topography. The level of imperviousness was estimated based on the imperviousness value used in the Rational Method hydrologic modeling for each subarea in order to be consistent with the impervious values used in the Drainage Study. Because this project includes mass grading pads that will be developed in the future by others, certain conservative assumptions were made for modeling purposes to estimate the limit of the impervious cover for the post-project condition. The following procedure was used to model the P:\2468.20\Engr\Rcports\WQTR-FE\2468.20 WQTR FE.doc 25 post-project impervious cover: 1) each pad area was assigned an approximate limit of impervious area based on the expected impervious area of the proposed land-use, and 2) the impervious area is represented by a polygon inset within the future pad area. Therefore, the Post-Project Slope Analysis and Land Cover Exhibit shows impervious areas within the middle of each of the major drainage areas with flat pervious areas around the outer edges. This was done only to approximate the average impervious condition of the proposed development envelope. The site planning and landscaping areas have not been designed yet for the future pads, so the majority of the area was assumed to be impervious in order to provide a conservative estimate for the hydromodiflcation analysis. For a quick reference summary, the percent impervious assumption values corresponding to the future developable pads are shown on the Post-Project Land Cover exhibit in Appendix E. Future refinements of the individual site plans for the individual lots during final engineering may warrant refinements to the input data used in the SDHM model (if the drainage areas change drastically during future site development), but, in general terms, the modeling was conservative to accommodate the range of imperviousness for future pad development. Therefore, the future developments within the project area should not need to provide additional treatment control or hydromodification control because the regional facilities have been sized with the analysis included in this report to accommodate the future condition. Because these BMPs will be built with the grading plans as regional facilities, but the site planning for the future pads has not been completed yet, the basin sizing may be re-visited during future site plan submittals, if required. If the drainage areas and/or imperviousness of the future pads are significantly higher from the assumed values, additional modeling or additional revisions may be required. P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 26 Basin Stage-Volume-Discharge Modeling Each basin was modeled using SDHM with a composite outlet structure and the stage-volume relationship was tabulated based on the current grading design. The stage/area/volume/discharge relationship was calculated with PondPack and then input into SDHM with a stage/storage/discharge (SSD) table to model the final design for the outlet structure. With the proposed design, the orifice to control hydromodification flows is placed on the imderdrain outlet within the gravel section. Other orifices on the basin outlet structure are set above the elevation corresponding to the water quality volume to ensure that the fiill water quality volume drains through the bioretention sandy loam material instead of bypassing to the storm drain system. Note that this design is very conservative from a water quality perspective. Therefore, both water quality and hydromodification requirements are achieved with this design. This procedure was selected in order to model both the water quality and hydromodification mitigation requirements and to accurately represent the bottom stages of the basins for accurate low-flow orifice sizing. The volume of the gravel layer in the bioretention portion of the basin was also added to the SSD table based on the assumed porosity of 0.4. Therefore, the storage within the gravel layer was included in the modeling for the stage-volume relationship. Bioretention Area Modeling SDHM has two options for modeling bioretention basins. The first option is using the standard bioretention element within SDHM and the second option is using the SSD element to model the bioretention basin geometry. Because the grading for the proposed bioretention basins are curvilinear and not a standard rectangular shape, the SSD table approach was used instead of the standard bioretention element. The stage-storage relationship was calculated with the contour P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 27 information on the grading plan and the SSD table was exported from Pondpack and imported into SDHM. The bioretention basins will be lined with an impermeable liner per the recommendations of the geotechnical engineer. For this reason, the modeling in SDHM did not include any native infiltration into subgrade. Note that the project is not required to utilize the area sizing factors per the default HMP tables because sophisticated modeling with SDHM was used to satisfy the hydromodification requirements instead of utilizing the simplistic HMP table approach. Further, the default flow- through planter HMP tables are not applicable to the project because of the multiple soil types within the project. (The tables can only be used if the drainage area consists of a single hydrologic soil group type). The proposed bioretention/hydromodification basins have been designed with an area (A) times ranoff factor (C) ratio as listed in the summary table in Appendix C. Some of the basins are designed with the bioretention portion of the basin extending along the full bottom of the basin. Other basins are designed with the bioretention portion extending to a smaller portion of the basin bottom. However, the minimum bioretention sandy loam area was designed such that the highest point of the bioretention section area was at least as high as the elevation corresponding to the water quality volume elevation. Therefore, for all basins, the water quality volume can pond up to the elevation of the most upstream end of the bioretention sandy loam mix at a minimum and infiltrate into the sandy loam material for treatment. Refer to the summary table in Appendix 3 and the basin detail sheet in Appendix E. The basins will be dual purpose to achieve the flow-duration requirements set forth in the County HMP, and will also address the stormwater quality treatment criteria set forth in the MS4 Permit as a regional post-constraction treatment BMP for the developed area. The proposed Bioretention/Hydromodification basins are both LID BMPs, freatment control P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 28 BMPs, and hydromodification management controls. The detailed calculations are included in Appendix D. Drawdown Time The HMP and/or water quality (WQ) drawdown time is the time it takes for the basin to empty the HMP and/or WQ volume. Basin draw-down times were estimated using PondPack, based on the stage-storage-discharge relationship of each basin. Per Section 6.4.6 of the County HMP, the minimum drawdown time to comply with Department of Environmental Health (DEH) guidelines is 96 hours. This standard has been set to minimize mosquito habitat and reduce the public health risk for West Nile Viras. This project complies with the DEH guidelines and, therefore, a separate vector control maintenance plan is not required. The drawdown calculations are included in Appendix D, and indicate that each of the drawdovm times for each of the basins is less than the 96 hour time limit. 5.2 Modeling Results There are five (5) Points of Compliance (POC) for the project and the SDHM analysis is organized accordingly. Each drainage basin will employ similar strategies for compliance with the HMP. Runoff from each basin will be directed to permanent storm water management features in the form of bioretention facilities which will meet both hydromodification and water quality treatment requirements. Chang Consultants prepared a report titled, "Hydromodification Screening for Quarry Creek," dated October 3, 2012, which summarized the results of a channel screening analysis and determined that P:V2468.20VEngi\Reports\WQTR-FE\2468.20 WQTR FE.doc 29 the lower flow threshold of 0.5Q2 is appropriate for the Quarry Creek project. Therefore this lower flow threshold was used in the continuous simulation analysis. Summary of Results and SDHM Output Based on the selected basin outlet configurations and basin elevation-volume relationship, the flow- duration requirements are satisfied with the proposed design. The outflow structures are included on Sheet 15 of the grading plans (DWG 484-5A), included for reference in Appendix E. The basin design and results summary is included in the table summary below.

P;\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 32 7.0 OPERATION AND MAINTENANCE The property owner shall ensure the ongoing maintenance for the permanent stormwater facilities proposed for the project as necessary for full operation of each facility. The owner will be responsible for properly disposing of waste material from their assumed areas within the project site, maintaining landscaping throughout those areas in a manner that will prevent soil erosion and minimize sediment transport, and maintaining drainage facilities located throughout the project area in a clean manner and in good repair. In addition, the owner will be responsible for maintaining all stormwater facilities that are private. Public storm drains (with the associated storm drain markers) and other public facilities will be maintained by the City of Carlsbad. Typical Maintenance Procedures for Stormwater Facilities The discussions below provide inspection criteria, maintenance indicators, and maintenance activities for the storm water facilities. Bioretention/Hydromodification Detention Facilities • Inspect basin facilities at least twice annually for erosion, damage to vegetation, and sediment and debris accumulation, preferably at the start and end of the wet season to be sure the area is ready for winter and to schedule follow-up maintenance, if necessary. Inspection should also occur after periods of heavy rainfall to ensure continued functionality of each system (i.e. - 0.5 inch storm events or greater). • Grass height and mowing frequency (if appropriate) may not have a large impact on pollutant removal. Consequently, mowing may only be necessary once or twice a year for safety or aesthetics or to suppress weeds and woody vegetation, but may be mowed more often for landscaping purposes. P:\2468.20\Eiigr\Reports\WQTR-FE\2468.20 WQTR FE.doc 33 • Trash tends to accumulate in basin detention facilities. The need for litter removal is determined through periodic inspection, but litter should always be removed prior to mowing. • Sediment accumulating in basin detention facilities should be removed when it builds up to 75 mm (3 in.) at any spot, or covers vegetation. • Regularly inspect basin detention facilities for pools of standing water. Basins can become a nuisance and promote mosquito breeding in standing water if obstructions develop (e.g. debris accumulation, invasive vegetation) and/or if proper drainage is not implemented and maintained. • Outfall locations that enter or exit facilities should be checked for erosion, ponding, trash/debris, and other stractural damage. • Perforated underdrains within gravel layer beneath sandy loam material should be inspected for obstructions and cleaned out periodically. The orifice restrictor plates on each underdrain outlet into the concrete riser stractures should be inspected on a regular basis and cleaned out when needed. Bio Clean Water Polisher Up Flow Media Filter Inspection/maintenance of the Bio Clean Water Polisher Up Flow Media Filter must be performed by properly trained personnel. Maintenance may involve handling of potentially hazardous material. Therefore the maintenance operator may need to be properly trained in handling and disposal of hazardous waste. The party responsible to ensure implementation and funding of maintenance of permanent BMPs will be responsible to select a maintenance contractor for maintenance of the Bio Clean Water Polisher Up Flow Media Filter who meets this requirement, and to contract for additional cleaning and disposal services as necessary if non-routine cleaning and disposal is required. There are several storm drain cleaning service providers who are able to inspect and/or maintain this product. P;\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 34 This type of maintenance is usually performed via a service contract with a specialized maintenance company. Contractors hired to perform cleaning of the underground units will be certified to perform the cleaning operation. The contractors will be experienced in using vacuum equipment to clean underground stormwater treatment units, will have confined space certification from OSHA, and will follow proper disposal requirements for local and state requirements. The manufacturer of the unit (Bio Clean Environmental Services) may be contracted to perform the maintenance, or another entity that specializes in stormwater BMP maintenance can be contracted for the work as long as they meet the minimum requirements. For a suggested list of minimum requirements that the owner should look for in choosing a maintenance contractor, refer to the following list: company that owns a vacuum track with at least 500 gallons of capacity, utilizes at least a two- person maintenance crew for safety issues, certified in traffic control, has proper insurance on their vehicles, and provides manifests for hydrocarbon media disposal and dewatering tanks disposal for record-keeping purposes. Each unit will require semi-annual inspections and it is recommended that maintenance be performed semi-annually or annually, depending on pollutant generation rates. Each unit will need to be inspected for debris accumulation and media performance. The separator chambers of the units should be cleaned via vacuum track, the media blocks should be replaced, and a pressure washer should be used to wash the debris screen. For specific information, refer to the Operation and Maintenance Manual provided by the manufacturer. A copy of the manual is included in Appendix F.

When the media is spent it is typically indicated by a change in color of the material. • Damage to intemal components within the product. If inspection indicates that intemal components within the product are damaged, additional non- routine maintenance will be required to repair or replace the damaged parts as applicable. The party responsible to ensure implementation and funding of maintenance of permanent BMPs shall contract for additional cleaning and disposal services as necessary if non-routine cleaning and disposal is required. In addition to the stormwater facilities intended as part of the IMP design, the following identifies additional LID and source control BMPs that required routine inspection and maintenance: Landscaped Areas Inspection and maintenance of the vegetated areas may be performed by the landscape maintenance contractor. During inspection, the inspector shall check for the maintenance indicators given below: • Erosion in the form of rills or gullies P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 36 • Ponding water • Bare areas or less than 70% vegetation cover • Animal burrows, holes, or mounds • Trash Routine maintenance of vegetated areas shall include mowing and trimming vegetation, and removal and proper disposal of trash. If erosion, ponding water, bare areas, poor vegetation establishment, or disturbance by animals are identified during the inspection, additional (non-routine) maintenance will be required to correct the problem. For ponding water or erosion, see also inspection and maintenance measures for irrigation systems. In the event that any non-routine maintenance issues are persistently encountered such as poor vegetation establishment, erosion in the form of rills or gullies, or ponding water, the party responsible to ensure that maintenance is performed in perpetuity shall consult a licensed landscape architect or engineer as applicable. As applicable, IPM procedures must be incorporated in any corrective measures that are implemented in response to damage by pests. This may include using physical barriers to keep pests out of landscaping; physical pest elimination techniques, such as, weeding, squashing, trapping, washing, or pruning out pests; relying on natural enemies to eat pests; or proper use of pesticides as a last line of defense. More information can be obtained at the UC Davis website (http://www.ipm.ucdavis.edu/WATER/U/index.html). Concrete Stencils or Identification Markers Inspection and maintenance of the concrete stencils may be performed by the building/facilities maintenance contractor or other employees of the project owner, as applicable. In addition, there P:\2468.20\Engr\Reports\WQTR-FE\2468.20 WQTR FE.doc 37 may be storm drain maintenance contractors who will perform this service for a fee. During inspection, the inspector(s) shall check to ensure that faded, vandalized, or otherwise unreadable concrete stencils are repaired or replaced as applicable. There are no routine maintenance activities for the concrete stamping. If inspection indicates the concrete stamping is intact, no action is required. Irrigation Systems Inspection and maintenance of the irrigation system may be performed by the landscape maintenance contractor. During inspection, the inspector shall check for the maintenance indicators given below: • Eroded areas due to concentrated flow • Ponding water • Refer to proprietary product information for the irrigation system for other maintenance indicators, as applicable Refer to proprietary product information for the irrigation system for routine maintenance activities for the irrigation system, as applicable. If none of the maintenance indicators listed above are identified during inspection of the irrigation system, no other action is required. If any of the maintenance indicators listed above are identified during the inspection, additional (non-routine) maintenance will be required to restore the irrigation system to an operable condition. If inspection indicates breaks or leaks in the irrigation lines or individual sprinkler heads, the affected portion of the irrigation system shall be repaired. If inspection indicates eroded areas due to concentrated flow from the irrigation system, the eroded areas shall be repaired and the irrigation system shall be adjusted or repaired as applicable to prevent further erosion. If inspection indicates ponding water P;\2468.20VEngr\Reports\WQTR-FE\2468.20 WQTR FE.doc 38 resulting from the irrigation system, the irrigation system operator shall identify the cause of the ponded water and adjust or repair the irrigation system as applicable to prevent ponding water. Refer to proprietary product information for the irrigation system for other non-routine maintenance activities as applicable. Inspection and Maintenance Frequency Typically, maintenance requirements are site and product specific, and will depend on the particular land use activities and the amount of gross pollutants and sediment generated within the drainage areas. If it is determined during the regularly scheduled inspection and routine maintenance that the BMPs/IMPs require more frequent maintenance to remove accumulated sediment, trash or debris, it may be necessary to increase the frequency of inspection and routine maintenance. Table 7-1 lists the stormwater facilities to be inspected and maintained and the minimum frequency of inspection and maintenance activities. TABLE 7-1.

The typical maintenance activities for landscaped areas and bioretention facilities can generally be accomplished by typical landscape maintenance personnel. The contiacting of additional services may be necessary if non-routine cleaning, disposal or repair is required for any of the project's storm water facilities. If evidence of illegal dumping of hazardous materials is identified in a storm water facility, the illegally dumped materials shall be cleaned up and disposed of properly. Specialized clean up and disposal of illegally dumped hazardous materials may be outside of the owner expertise. In this event, the owner shall contract for additional cleaning and disposal services as necessary if non- routine cleaning and disposal is required.

To view the SUSMP, refer to the Engineering Standards (Volume 4, Chapter 2). Initially this questionnaire must be completed by the applicant in advance of submitting for a development application (subdivision, discretionary permits and/or construction permits). The results of the questionnaire determine the level of storm water standards that must be applied to a proposed development or redevelopment project. Depending on the outcome, your project will either be subject to 'Standard Stormwater Requirements' or be subject to additional criteria called 'Priority Development Project Requirements'. Many aspects of project site design are dependent upon the storm water standards applied to a project. Your responses to the questionnaire represent an initial assessment of the proposed project conditions and impacts. City staff has responsibility for making the final assessment after submission of the development application. If staff determines that the questionnaire was incorrectly filled out and is subject to more stringent storm water standards than initially assessed by you, this will result in the return of the development application as incomplete. In this case, please make the changes to the questionnaire and resubmit to the City. If you are unsure about the meaning of a question or need help in determining how to respond to one or more of the questions, please seek assistance from Land Development Engineering staff. A separate completed and signed questionnaire must be submitted for each new development application submission. Only one completed and signed questionnaire is required when multiple development applications for the same project are submitted concurrently. In addition to this questionnaire, you must also complete, sign and submit a Project Threat Assessment Form with construction pennits for the project. Please start by completing Step 1 and follow the instructions. When completed, sign the form at the end and submit this with your application to the city. ' TO BE COMPLETEDflR ALL PROJECTS ' To determine if your project is a priority development project, please answer the following questions: YES NO 1. Is your project LIMITED TO constructing new or retrofitting paved sidewalks, bicycle lanes or trails that meet the following criteria: (1) Designed and constructed to direct storm water runoff to adjacent vegetated areas, or other non-erodible permeable areas; OR (2) designed and constructed to be hydraulically disconnected from paved streets or roads; OR (3) designed and constructed with permeable pavements or surfaces in accordance with USEPA Green Streets guidance? X 2. Is your project LIMITED TO retrofitting or redeveloping existing paved alleys, streets, or roads that are designed and constructed in accordance with the USEPA Green Streets guidance? K If you answered "yes" to one or more of the above questions, then your project is NOT a priority development project and therefore is NOT subject to the storm water criteria required for priority development projects. Go to step 4, mark the last box stating "my project does not meet PDP requirements" and complete applicant Information. If you answered "no" to both questions, then go to Step 2.

These facilities normally consist of a grass buffer strip, sand bed, ponding area, organic layer or mulch layer, planting soil, and plants. The runoffs 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; Chestei-field 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) • Low • High A Medium CASQA California Stormwater Quality Association January 2003 California Stormwater BMP Handbook New Development and Redevelopment www.cabmphandbooks.com 1 of 8 TC-32 Bioretention 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 ft=^ 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 2 of 8 California Stormwater BMP Handbool< January 2003 New Development and Redevelopment www.cabmptiandbooks.com Bioretention TC-32 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 fi-om 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. January 2003 California Stormwater BMP Handbook New Development and Redevelopment www.cabmphandbooks.com 3 of 8 TC-32 Bioretention 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 vridth 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. 4 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Bioretention TC-32 Soil tests should be performed for every 500 cubic yards (382 cubic meters) of planting soil, vrith 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 vriU 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 vrinds, 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 January 2003 California Stormwater BMP Handbook 5 of 8 New Development and Redevelopment www.cabmphandbooks.com TC-32 Bioretention 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 vrith 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) vrill 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 (Coffinan, 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, vrith 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. 6 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Bioretention TC-32 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 ovmer's landscape, reducing the public burden to maintain large centralized facilities. Maintenance Cost The operation and maintenance costs for a bioretention facility vrill be comparable to those of typical landscaping required for a site. Costs beyond the normal landscaping fees vrill include the cost for testing the soils and may include costs for a sand bed and planting soil.

Bioretention Systems Typical Bioretention cross section, Anatomy of a Rain Garden, n.d. Bioretention systems are essentially a surface and sub-surface water filtration system. In function they are similar to sand filters. Bioretention systems incorporate both plants and underlying filter soils for removal of contaminants. These facilities normally consist of a treatment train approach: filter strip, sand bed, ponding area, organic layer, planting soil, and plants. CHARACTERISICS • Effective in removing sediments and attached pollutants by filtration through surface vegetation, ground cover and underlying filter media layer • Delay runoff peaks by providing retention capacity and reducing flow velocities. • Vegetation increases aesthetic value while also enhancing filtration capacity and helping to maintain the porosity of the filter media. • Can be constructed as either large or small scale devices, with native or amended soils. • Small scale units are usually located in a residential planter box that filters collected stormwater through the filter media and to an outlet. • Larger scale devices work on the same methodology, however are generally located along the streetscapes and retarding basins over large open areas. • In addition, there are two main types of bioretention system: Non-conveyance systems, which generally pond runoff volume, and Conveyance, which generally convey minor storm events along longitudinal charmels. Such conveyance systems generally include an amended soil layer under the surface for additional storage and filtration APPLICATION • Effective in removing medium to fine size sediments and attached pollutants (such as nutrients, free oils/grease and metals), but typically have higher pollutant Final -42- 12/31/2007 The County of San Diego LID Appendix removal efficiencies for a wider range of contaminants due to enhanced filtration/biological processes associated with the surface vegetation. • Best suited to small residential, commercial, and industrial developments with high percentages of impervious areas, including parking lots, high density residential housing, and roadways. • Aesthetic benefits due to the surface vegetation make bioretention systems appealing for incorporation into streetscape and general landscape features. DESIGN • Provide a gentle slope for overland flow and adequate water storage. No water should be allowed to pond in the bioretention system for longer than 72 hours. • Usually designed in conjunction with swales and other devices upstream so as to reduce filter clogging and provide water treatment (treatment train). • Filter media employed is usually the plant growing material, which may comprise soil, sand and peat mixtures. • "Planting box" type systems should be restricted to very small catchment areas. • A subdrain system should be included in urban areas along with associated cleanout to facilitate maintenance. • For more precise design techniques, see: CASQA (2003, January) Califomia Stormwater BMP Handbook: New Development and Redevelopment MAINTENANCE • Generally, only routine periodic maintenance typical of any landscaped area (mulching, plant replacement, pruning, weeding) is necessary. • Regular inspections and maintenance are particularly important during the vegetation establishment period. • Routine maintenance should include a biannual health evaluation of the trees and shrubs and subsequent removal of any dead or diseased vegetation. • Other potential tasks include soil pH regulation, erosion repair at inflow points, mulch replenishment, unclogging the under-drain, and repairing overflow structures. LIMITATIONS • Adequate sunlight is required for vegetation growth. • The use of irrigation may not meet State water conservation goals. Appropriate drought-tolerant plants should be considered. • Placement may be limited by the need for upstream pre-treatment so as to avoid filter clogging (treatment train). • Contributing drainage area should be less than 1 acre for small-scale, on-lot devices • Bioretention (a BMP with incidental infiltration) is not an appropriate BMP when: o the seasonal high groundwater table is within 6 feet of the ground surface (US EPA 1999) o at locations where or where surrounding soil stratum is unstable • exceptions to the 6 foot separation can be made when: o the BMP is designed with an under-drain and approved by a qualified licensed professional, or when: Final -43- 12/31/2007 The County of San Diego LID Appendix o written approval of a separation in the interval of 4-6 feet has been obtained by the Regional Water Quality Control Board and the Department of Enviroimiental Health. • Site must contain sufficient elevation relief so that subdrain system may discharge to receiving swale, curb or storm drain system. ECONOMICS • Construction cost estimates for a bioretention area are slightly greater than those for the required landscaping for a new development (EPA, 1999). • The operation and maintenance costs for a bioretention facility will be comparable to those of typical landscaping required for a site. (CASQA, 2003) • Maintenance costs are projected at 5-7% of the construction cost annually. REFERENCES • Califomia Stormwater Quality Association.
