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

On line: http: / / www.epa.gov/npdes/menuofbmps/poll 16 .htm 6 of 6 California Stormwater BMP Handbook January 2003 Industrial and Commercial www.cabmphandbooks.com storm Drain Signage SD-13 Design Objectives IWaximize infiltration Provide Retention Slow Runoff Minimize Impen/ious Land Coverage Protiibit Dumping of Improper Materials Contan Poilutants Collect aid Convey Description Waste materials dimiped into storm drain inlets can have severe impacts on receiving and ground waters. Posting notices regarding discharge prohibitions at storm drain inlets can prevent waste dumping. Storm drain signs and stencib are highly visible source controls that are t3T)ically placed directly adjacent to storm drain inlets. Approach The stencil or affixed sign contains a brief statement that prohibits dumping of improper materials into the urban mnoff conveyance system. Storm drain messages have become a popular method of alerting the public about the effects of and the prohibitions against waste disposal. Suitable Applications Stencils and signs alert the public to the destination of pollutants discharged to the storm drain. Signs are appropriate in residential, commercial, and industrial areas, as weU as any other area where contributions or dumping to storm drains is likely. Design Considerations Storm drain message markers or placards are recommended at all storm drain inlets within the boundary of a development project. The marker should be placed in clear sight facing toward anyone approaching the inlet &om either side. All storm drain inlet locations should be identified on the development site map. Designing New Installations The following methods should be considered for inclusion in the project design and show on project plans. • Provide stenciling or labeling of aU storm drain inlets and catch basins, constructed or modifie*!, withinthe project area with prohibitive language. Examples include "NO DUMPING January 2003 Califomia Stormwabar BMP Handtxwk New Development and Redevetapment www.cabmphandbooks.com lof 2 SD-13 Storm Drain Signage - DRAINS TO OCEAN" and/or other graphical icons to discourage iUegal dumping. • Post signs with prohibitive language and/or graphical icons, which prohibit illegal dumping at public access points along channels and creeks within fhe project area. Note - Some local agencies have approved specific signage and/or storm drain message placards for use. Consult local agency stormwater staff to determine specific requirements for placard types and methods of application Redeveloping Existing InstaUations Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) define "redevelopment" in terms of amounts of additional impervious area, increases ingress floor area and/or exterior constmction, and land disturbing activities with stmcmral or impervious surfaces. If the project meets the definition of "redevelopment", then the requirements stated under" designing new installations" above should be included in all project design plans. Additional Information Maintenance Considerations • Legibility of markers and signs should be maintained. If required by the agency with jurisdiction over the project, the owner/operator or homeowner's association should enter into a maintenance agreement with the agency or record a deed restriction upon the property title to maintain the legibihty of placards or signs. PZacemenr • Signage on top of curbs tends to weather and fade. • Signage on face of curbs tends to be worn by contact with vehicle tires and sweeper brooms. Supplemental Information Examples m Most MS4 programs have storm drain signage programs. Some MS4 programs will provide stencUs, or arrange for volunteers to stencil storm drains as part of their outreach program.

A sump pump, wet vacuum or similarly effective device must be used to collect the runoff and loose materials. The collected runoff and sohds must be disposed of properly. • If soaps or detergents are not used, and die surrounding area is paved, wash water runoff does not have to be collected but must be screened. Pressure washers must use filter fabric or some odier type of screen on tlie groimd and/or in he catch basin to trap the particles in wash water runoff. • If you are pressure washing on a grassed area (with or without soap), runoff must be dispersed as sheet flow as much as possible, rather than as a concentrated stream. The wash nmoff must remain on the grass and not drain to pavement. Ensure that this practice does not kill grass. Landscaping Activities m Do not apply any chemicals (insecticide, herbicide, or fertilizer) du'ectly to surface waters, miless the appUcation is approved and pennitted by the state. • Dispose of grass clippings, leaves, sticks, or other collected vegetation as garbage, or by composting. Do not dispose of collected vegetation into waterways or storm drainage systems. • Use mulch or other erosion control measures on exposed soUs. • Check irrigation schedules so pesticides vwll not be washed away and to minimize non- stomiwater discharge. Building Repair, Remodeling, and Constniction m Do not dump any toxic substance or liquid waste on the pavement, the gromid, or toward a storm drain. • Use ground or drop cloths imdemeath outdoor painting, scrapmg, and sandblasting work, and properly dispose of collected material daily. • Use a ground doth or oversized tub for activities such as paint mixing and tool cleaning. • Clean paint brushes and tools covered with water-based pauits m sinks coimected to sanitary sewers or in portable container that can be dumped into a sanitaiy sewer drain. Brushes and tools covered with non-water-based paints, finishes, or other materials must be deaned in a manner that enables collection of used solvents (e.g., paint tliimier, tmpentine, etc.) for recychng or proper disposal. 2 of 5 California Stormwater BMP Handbook January 2003 Municipai www.cabmphandbooks.com Building & Grounds Maintenance SC-41 • Use a storm drain cover, filter fabric, or similarly effective runoff control medianism if dust, grit, wash water, or other pollutants may escape fhe work area and enter a catch basin. The containment device(s) must be m place at fhe begmning of the work day, and accumulated dirty runoff and solids must be collected and disposed of before removing the containment device(s) at the end of the work day. • If you need to de-water an excavation site, you may need to filter the water before discharguig to a catch basin or off-site. In whkh case you should direct fhe water through hay bales and filter fabric or use other sediment filters or traps. • Store toxic material under cover with secondaiy containment during predpitation events and when not in use. A cover would include tarps or other temporaiy cover material. Mowing, Trimming, and Planting • Dispose of leaves, sticks, or other collected vegetation as garbage, by composting or at a permitted landfiQl. Do not dispose of collected vegetation into waterways or storm drainage systems. • Use mulch or other erosion control measm-es when soils are exposed. • Place temporarily stockpfled material away from watercourses and drain inlets, and berm or cover stockpiles to prevent material releases to the storm drain system. • Consider an altemative approach when bailmg out muddy water; do not put it in the storm draui, pour over landscaped areas. • Use hand or mechanical weeding where practical. Fertilizer and Pesticide Management m Follow all federal, state, and local laws and regulations goveming the use, storage, and disposal of fertilizers and pestiddes and training of applicators and pest control advisors. • Follow manufacturers' recommendations and label directions. Pestiddes must never be applied if predpitation is occuring or predicted. Do not apply insectiddes within loo feet of surface waters such as lakes, ponds, wetlands, and streams. • Use less toxic pestiddes that will do the job, whenever possible. Avoid use of copper-based pestiddes if possible. • Do not use pestiddes if rain is expected. • Do not nux or prepare pestiddes for application neai* storm drains. • Use the minimum amount needed for the job. • Calibrate fertihzer distributors to avoid excessive appHcation. • Employ techniques to mmimize off-target application (e.g. spray drift) of pesticides, iiicluduig consideration of alternative application techniques. January 2003 California Stormwater BMP Handbook 3 of 5 Municipal www.cabmphandbooks.com SC-41 Building & Grounds Maintenance • Apply pestiddes only when wind speeds are low. • Work fertilizers into tlie soil ratlier than dumping or broadcasting them onto the surface. • Inigate slowly to prevent runoff and then only as much as is needed. • Qean pavement and sidewalk if fertilizer is spilled on these sm-faces before applying irrigation water. • Dispose of empty pestidde contamers according to the uisfcructions on the container label. • Use up the pesticides. Rinse containere, and use rinse water as product. Dispose of miused pestidde as hazardous waste. • Implement storage requirements for pestidde products witli guidance fi-om the local fire department and County Agricultural Commissioner. Provide secondaiy contaimnent for pestiddes. Inspection m Inspect irrigation system periodicaBy to ensure that the right amount of water is being applied and that excessive runoff is not occm-ring. Minimize excess watering, and repafr leaks m the irrigation system as soon as they are observed. Traimngi • Educate and ti-ain employees on use of pestiddes and in pestidde appHcation teduiiques to prevent pollution. • Train employees and conh-actors in proper techniques for spiH contamment and deanup. • Be sm-e the frequency of braining takes into account fhe complexity of tlie operations and the nature ofthe staff. Spill Response cmd Prevention m Refer to SC-ii, Spill Prevention, Control & Qeanup • Keep your SpiU Prevention Control and countermeasure (SPCC) plan up-to-date and implement accordingly. • Have spiU deanup materials readily available and in a known location. • Cleanup spills immediately and use dry methods if possible. • Properly dispose of spill deanup material. Other Considerations m Alternative pest/weed coiiti-ols may not be available, suitable, or effective in many cases. California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Building & Grounds Maintenance SC-41 Requirements Costs • Overall costs should be low in comparison to other BMPs. Maintenance • Sweep paved areas regularly to collect loose particles, and wipe up spills with rags and other absorbent material immediately, do not hose down the area to a storm drain. Supplemental Information Further Detail ofthe BMP Fire Sprinkler Line Flushing Building fire sprinkler lme flushing may be a source of non-stormwater runoff poUution. The water entering the system is usually potable ^vater though in some areas it may be non-potable reclaimed wastewater. There are subsequent factors diat may drastically reduce the quality of the water in such systems. Black iron pipe is usuaHy used since it is cheaper than potable pipmg but it is subject to rusting and results in lower quaHty water. Initiafly fhe black iron pipe has an oil coating to protect it from rusting between manufacture and installation; this will contaminate fhe water from the first flush but not from subsequent flushes. Nitrates, poly- phosphates and other corrosion inhibitors, as well as fire suppressants and antifreeze may be added to the sprinkler water system. Water generally remains in the sprinkler system a long time, typically a year, between flushes and may accumulate iron, manganese, lead, copper, nickel and zinc. The water generally becomes anoxic and contains Hving and dead bacteria and breakdown products from chlorination. This may result in a significant BOD problem and the water often smells. Consequentiy dispose fire sprinkler Hne flush water into the sanitaiy sewer. Do not aUow discharge to storm drain or infiltration due to potential high levels of poHutants in fire sprinkler line water.

This water, if discharged to the storm drain system, can be toxic to aquatic life. In lakes, lagoons, and fountains, fhe pollutants of concem are chemical algaeddes that are added to control algae mainly for aesthetic reasons (visual and odor). FoHowing the procedtures noted in this fact sheet wiH reduce the pollutants in tins discharge. Approach PoUution Prevention • Prevent algae problems with regular deaning, consistent adequate chlorine levels, and well-maintained water filtration and drcuiation systems. • Manage pH and water hardness to minimize conosion of copper pipes. Suggested Protocols Pools and Fountains • Do not use copper-based algaeddes. Control algae widi chlorine or other altematives, such as sodium bromide. • Do not dischaige water to a street or storm drain when draining pools or fountains; disdiarge to the sanitary sewer if pennitted to do so. If water is dechlorinated with a neutralizing chemical or by allowing chlorine to dissipate for a few days (do not use fhe fadlity during this time), the water may be recycled/reused by draining it graduaUy onto a landscaped area. Water must be tested prior to disdiarge to ensure that chlorine is not present. • Prevent backflow if draining a pool to the sanitaiy sewer by maintaining an "air gap" between the dischaige iine and the sewer line (do not seal the coimection between the hose and sewer Hne). Be sure to caH the local wastewater tieatment plant for fiirther guidance on flow rate restiictions, backflow prevention, and handling spedal deaning waste (such as acid wash). Discharge flows should be kept to tlie low levels typicaUy possible through a garden hose. Higher flow rates may be prohibited by local ordinance. • Provide drip pans or buckets beneath drain pipe coimections to catch leaks. Tliis wiU be especiaUy pertinent if pool or spa water that has not been dechlorinated is pumped tiirough piping to a discharge location.

Dispose of spent diatomaceous earth in the garbage. Spent diatomaceous earth cannot be discharged to surface waters, storm drainage systems, septic systems, or on the ground. • If there is not a suitable dirt area disdiarge filter backwash or rinsewater to the sanitary sewer if pennitted to do so by die local sewering agency. Lakes and Lagoons m Reduce feitUizer use in areas around die water body. Higli nitrogen fertiHzers can produce excess growth requuing more frequent mowing or trimming, and may contribute to excessive algae growth. • To conti-ol bacteria, discourage fhe pubHc from feeding buds and fish (i.e. place signs that prohibit feeding of waterfowl). • Consider introducing fish species that consume algae. Contad the California Department of Fish and Game for more information on this issue. • Mechanically remove pond scum (blue-green algae) using a 60 micron net • Educate the public on algae and that no conti-ols are necessary for certain types of algae that are beneficifd to the water body. • Ctoiitrol erosion by doing the following: - Maintain vegetative cover on banks to prevent soil erosion. Apply mulch or leave cHppmgs to serve as additional cover for soil stabilization and to reduce the vdodty of stormwater runoff. - Areas should be designed (sloped) to prevent mnoff and erosion and to promote better irrigation practices. - Provide energy dissipaters (e.g. riprap) along banks to minimize potential for erosion. - Confine excavated materials to surfaces a\vay from lakes. Material must be covered if rain is expected. • Conduct inspections to detect iUegal dumping of clippings/cuttings in or near a lake. Materials found should be picked up and properly (Hsposed of • Avoid landscape wastes in and around lakes should be avoided by either using bagging equipment or by raanuaUy pickuig up the material. Collect trash and debris from withm water bodies where feasible • Provide and maintain trash receptacles near recreational water bodies to hold refuse generated by fhe pubHc. 2 of 4 California Stormwater BMP Handbook Januaty 2003 Municipal www.cabmphandbooks.com Fountain & Pool Maintenance SC-72 • Increase trash collection during peak visitation months (generaUy Jime, July and August). Training • Train maintenance personnel to test chlorine levels and to apply neutralizmg chemicals. • Train persoimel regarding proper manitenance of pools, ponds and lakes. SpiU Response and Prevention m Refer to SC-ii, SpiU Prevention, Control & Qeanup • Have spUl cleanup materials readily avaUable and in a known location. • Cleanup spUls immediately and use dry methods if possible. • Properly dispose of spiU deanup material. Other Considerations m Managers of pools located in sensitive areas or adjacent to shorelines should check with the appropriate authorities to detemiine if code requirements apply. • Qeanup activities at lakes and lagoons may create a slight disturbance for local aquatic species. Ifthe lake is recognized as a wetland, many activities, mcluding maintenance, may be subject to regulation and permitting. Requirements Costs • Tlie maintenance of pools and lakes is aheady a consideration of most munidpal pubHc works departments. Therefore the cost assodated with this BMP is mmimal and only reflects an increase in employee training and public outreach. Maintenance Not applicable Supplemental Information Further Detail ofthe BMP When dredguig is conducted, adhere to fhe following: • Dredge with shovels when laying/niaintauiing pipes. • To determine amount to dredge, determine rate of volume loss due to sediments. « For large lakes, dredge every lo years. • When dredging small lakes, drain lake. • Wlien dredging large lakes, use vacuum equipment. • After di-edging test sedunent pUes for proper disposal.

Sweeping and vacuuming prevents sediment from the project site from entering storm drains or receiving waters. Suitable Applications Sweeping and vacuuming are suitable anywhere sediment is tracked from the project site onto public or private paved streets and roads, typically at points of egress. Sweeping and vacuuming are also appHcable during preparation of paved surfaces for final paving. Limitations Sweeping and vacuuming may not be effective when sediment is wet or when tracked soil is caked (caked soil may need to be scraped loose). Implementation • ControHing the number of points where vehicles can leave the site will allow sweeping and vacuuming efforts to be focused, and perhaps save money. • Inspect potential sediment tracking locations daily. • Visible sediment tracking should be swept or vacuumed on a daily basis. • Do not use kick brooms or sweeper attachments. These tend to spread the dirt rather than remove it.

Expect rental rates from $58/hour (3 yds hopper) to $88/hour (9 yd3 hopper), plus operator costs. Hourly production rates vary vnth the amount of area to be swept and amount of sediment. Match the hopper size to the area and expect sediment load to minimize time spent dumping. Inspection and Maintenance • Inspect BMPs prior to forecast rain, daily during extended rain events, after rain events, weekly during the rainy season, and at two-week intervals during the non-rainy season. • When actively in use, points of ingress and egress must be inspected daily. • When tracked or spiHed sediment is observed outside the constmction Hmits, it must be removed at least daily. More frequent removal, even continuous removal, may be required in some jurisdictions. • Be careful not to sweep up any unknown substance or any object that may be potentially hazardous. • Adjust brooms frequently; maximize efficiency of sweeping operations. • After sweeping is finished, properly dispose of sweeper wastes at an approved dumpsite.

Integrating and incorporating appropriate landscape planning methodologies into the project design is the most effective action that can be done to minimize surface and groundwater contamination from stormwater. Approach Landscape planning should couple consideration of land suitabiUty for urban uses with consideration of community goals and projected growth. Project plan designs should conserve natural areas to the extent possible, maximize natural water storage and infiltration opportunities, and protect slopes and channels. Suitable Applications Appropriate appHcations include residential, commercial and industrial areas planned for development or redevelopment. Design Considerations Design requirements for site design and landscapes planning should conform to appHcable standards and specifications of agencies with jurisdiction and be consistent with appHcable General Plan and Local Area Plan policies. January 2003 Califomia Stormwater BMP Handbook New Development and Redevelopment wvw.ca bmpha ndbooks.com lof 4 SD-10 Site Design & Landscape Planning Designing New Installations Begin the development of a plan for the landscape unit with attention to the following general principles: • Fonnulate fhe plan on the basis of clearly articulated community goals. CarefuHy identify conflicts and choices between retaining and protecting desired resources and community growth. • Map and assess land suitabiHiy for urban uses. Include the foHowing landscape features in the assessment: wooded land, open unwooded land, steep slopes, erosion-prone soils, foimdation suitabiHty, soil suitability for waste disposal, aquifers, aquifer recharge areas, wetlands, floodplains, surface waters, agricultural lands, and various categories of urban land use. When appropriate, the assessment can highUght outstanding local or regional resomces that the conimunity detennines should be protected (e.g., a scenic area, recreational area, threatened species habitat, farmland, fish mn). Mapping and assessment should recognize not only these resources but also additional areas needed for thefr sustenance. Project plan designs should conserve natural areas to the extent possible, maximize natural water storage and infiltration oppormnities, and protect slopes and channels. Conserve Natural Areas during Landscape Plarming If applicable, the following items are required and must be implemented in the site layout during the subdivision design and approval process, consistent with appHcable General Plan and Local Area Plan policies: • Cluster development on least-sensitive portions of a site while leaving the remaining land in a namral undismrbed condition. • Limit clearing and grading o f native vegetation at a site to fhe minimum amount needed to build lots, aUow access, and provide fire protection. • Maximize trees and other vegetation at each site by planting additio nal vegetation, clustering tree areas, and promoting the use of native and/or drought tolerant plants. • Promote natiiral vegetation by using parking lot islands and other landscaped areas. B Preserve riparian areas and wetlands- Maximize MtturaZ Water Storage and Infiltration Opportunities Within the Landscape Unit • Promote the conservation of forest cover. Building on land that is already deforested affects basin hydrology to a lesser extent than converting forested land. Loss of forest cover reduces interception storsge, detention in the organic forest floor layer, and water losses by evapotranspfration, resulting in large peak mnoff increases and either their negative effects or the expense of countering them with stmctural solutions. • Maintain namral storage reservoirs and drainage corridors, including depressions, areas of permeable soils, swales, and intermittent streams. Develop and implement poHcies and 2 of 4 California Stormwater BMP Handbook January 2003 New Devetopment and Redevelopment wvw.cabmphandbooks.com Site Design & Landscape Planning SD-10 regulations to discourage the clearing, filling, and channelization of these feamres. UtiHze them in drainage networks in preference to pipes, culverts, and engineered ditches. • Evaluating infiltration opportunities by referring to the stonnwater management manual for the jurisdiction and pay particular attention to the selection criteria for avoiding groundwater contamination, poor soils, and hydrogeological conditions that cause these facilities to fail. If necessary, locate developments with large amounts of impei-vious surfaces or a potential to produce relatively contaminated runoff away from groundwater recharge areas. Protection of Slopes and Channels during Landscape Design • Convey mnoff safely from the tops of slopes. • Avoid disturbing steep or unstable slopes. • Avoid disturbing natural channels. • StabiHze disturbed slopes as quickly as possible. • Vegetate slopes with native or drought tolerant vegetation. • Control and treat flows in landscaping and/or other controls prior to reaching existing natural drainage systems. • StabiUze temporary and permanent channel crossings as quickly as possible, and ensure that increases in ran-off velocity and frequency caused by the project do not erode the channel. • InstaU energy dissipaters, such as riprap, at the outiets of new storm drains, culverts, conduits, or channels that enter unlined channels in accordance with applicable specifications to minimize erosion. Energy dissipaters shaU be installed in such a way as to minimize impacts to receiving waters. • Line on-site conveyance channels where appropriate, to reduce erosion caused by increased flow velocity due to increases in tributary impervious area. The first choice for Hnings should be grass or some other vegetative surface, since these materials not only reduce mnoff velocities, but also provide water quaHty benefits from filtration and infiltration. If velocities in the channel are high enough to erode grass or other vegetative linings, riprap, concrete, soil cement, or geo-grid stabilization are other alternatives, • Consider other design principles that are comparable and equally effective. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) define "redevelopment" in terms of amounts of additional impervious area, increases in gross floor area and/or exterior construction, and land disturbing activities with stmcmral or impervious surfaces. The definition of" redevelopment" must be consulted to determine whether or not tiie requirements for new development apply to areas intended for redevelopment. Ifthe definition appHes, the steps outlined under "designing new installations" above should be followed. January 2003 Califomia Stormwater BMP Handbook 3 of 4 New Development and Redevelopment www.cabmphandbooks.com SD-10 Site Design & Landscape Planning Redevelopment may present significant opportunity to add featares which had not previously been implemented. Examples iaclude incorporation of depressions, areas of permeable soils, and swales in newly redeveloped areas.

The objective is to reduce the total volume and rate of ranoff from individual lots, and retain the pollutants on site tiiat maybe picked up from roofing materials and atmospheric deposition. Roof ranoff controls consist of directing the roof ranoff away from psved areas and mitigating flow to the storm drain system through one of several general approaches: dstems or rain barrels; dry wdls or infiltration trenches; pop-up emitters, and foundation planting. Tlie first thi-ee approaches requfre the roof runoff to be contained in a gutter and downspout system. Foundation planting provides a vegetated strip under the drip line ofthe roof Approach Design of individual lots for single-fanuly homes as weU as lots for higher density residential and commerdal stractures should consider site design provisions for containuig and infiltrating roof runoff or directing roof runoff to vegetative swales or buffer areas. Retained water can be reused for watering gardens, lawns, and trees. Benefits to the environment mclude reduced demand for potable water used for irrigation, improved stormwater quality, increased groundwater recharge, decreased ranoff volume and peak flows, and decreased flooding potential. Suitable Applications Appropriate appHcations include residential, commerdal and mdustrial areas planned for development or redevelopment. Design Considerations Designing New InstaUations Cisterns or Rain Barrels One method of addressing roof ranoff is to direct roof downspouts to dstems or rain bands. A cistern is an above ground storage vessel widi either a manually operated vahe or a pemianently open outlet Roof ranoff is temporarily stored and then released for irrigation or infiltration between storms. The number of rain January 2003 Califomia Stomiwater BMP Handbook New Development and Redevelopment www.cabmphandbook.com 1 of 3 SD-11 Roof Runoff Controls barrels needed is a function of fhe rooftop area. Some low unpact developers recommend that every house have at least 2 rain barrels, with a minimum storage capadty of lOOO liters. Roof barrels sei-ve several purposes induding mitigating the first flush from the roof which has a lugh volume, amount of contaminants, and fheraial load. Several types of rain barrels are commercially avaUable. Consideration must be given to selecting rain barrels that are vector proof and chUdproof . In addition, some barrels are designed with a bypass valve that filtere out grit and other contaminants and routes overflow to a soak-away pit or rain garden. If the dstem has an operable valve, the valve can be closed to store stonnwater for imgation or infUtration between storms. This system requfres continual monitoring by the resident or grounds crews, but provides greater flexibUity in water storage and metering. If a cistem is provided with an operable valve and water is stored inside for long periods, the dstem must be covered to prevent mosquitoes from breeding. A dstem system with a permanently open outiet can also provide for metering stormwater mnoff. Ifthe cistem outiet is si^ificantly smaUer tiian the size ofthe downspout inlet (say V4 to ¥2 inch diameter), runoff wUl buUd up inside the dstem during storms, and wiU empty out slowly after peak intensities subside. Tliis is a feasible way to mitigate the peak flow increases caused by rooftop impervious land coverage, espedaUy for the frequent, smaU storms. Dry wells and Infiltration Trenches Roof downspouts can be dfrected to dry wells or infiltration frenches. A dry weU is constmcted by excavatmg a hole in the ground and fiUing it with an open graded aggregate, and aUowing the water to fill the dry weU and infUtrate after the storm event An underground coimection from fhe downspout conveys water into the dry weU, aUowing it to be stored in the voids. To minimize sedimentation from lateral soU movement, fhe sides and top of die stone storage matrix can be wrapped in a permeable filter fabric, though the bottom may remain open. A perforated observation pipe can be inserted verticaUy into the dry weU to aUow for inspection and maintenance. In practice, dry wdls receiving runoff from single roof downspouts have been successfiU over long periods because they contain very little sediment They must be sized accordfrig to the amount of rooftop runoff received, but are typicaUy 4 to 5 feet square, and 2 to 3 feet deep, witii a minimum of i-foot soU cover over fhe top (maximum depth of 10 feet). To protect the fomidatioii, dry wdls must be set away from the buUding at least 10 feet. They must be instaUed iu solids tiiat accommodate infiitration. In poorly drained soils, dry weUs have veiy limited feasibility. Infiltration trendies function in a simUai- manner and would be particularly effective for larger roof areas. An infiltration trench is a long, narrow, rock-fiUed trench with no outiet that receives stormwater runoff. These are described under Treatment Controls. Pop-up Drainage Emitter Roof downspouts can be dfrected to an underground pipe diat daylights some distance from die building foundation, releasmg the roof runoff thiough a pop-up emitter. SimUar to a pop-up irrigation head, die emitter only opens when there is flow from the roof. The emitter remains flush to the ground during dry periods, for ease of lawn or landscape maintenance. 2 of 3 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbook.com Roof Runoff Controls SD-11 Foundation Planting Landscape planting can be provided aromid the base to allow increased opportunities for stormwater tnfUfration and protect die soU from erosion caused by concenti-ated sheet flow comuig off the roof Foundation plantings can reduce the physical impact of water on the soU and provide a subsurface matrix of roots that encourage mfiltration. These plantings must be sturdy enough to tolerate fhe heavy ranoff sheet flows, and periodic soU saturation. Redeveloping Existing Installations Various jurisdictional stonnwater management and mitigation plans (SUSMP, WQMP, etc.) define "redevelopment" ui tenns of amounts of additional impervious area, increases in gross floor area and/or exterior constmction, and land disturbing activities with strachn-al or unpervious surfaces.

Suitable Applications Appropriate appHcations include residential, commercial and industrial areas planned for development or redevelopment. (Detached residential single-family homes are typically excluded from this requfrement.) Design Considerations Designing New InstaUations The following methods to reduce excessive frrigation ranoff should be considered, and Hicorporated and implemented where determined applicable and feasible by the Permittee: • Employ rain-triggered shutoff devices to prevent frrigation after precipitation. • Design irrigation systems to each landscape area's specific water requirements. • Include design feataring flow reducers or shutoff valves triggered by a pressure drop to control water loss in the event of broken sprmkler heads or lines. • Implement landscape plans consistent with County or City water conservation resolutions, which may include provision of water sensors, programmable frrigation times (for short cycles), etc. January 2003 Califomia Stormwater BMP Handbook New Devetopment and Redevelopment www.cabmphandbooks.com 1 of 2 SD-12 Efficient Irrigation • Design tuning and appHcation metiiods of frrigation water to minimize the ranoffof excess frrigation water mto the storm water drainage system. • Group plants with similar water requirements in order to reduce excess frrigation runoff and promote surface fUtration. Choose plants with low irrigation requfrements (for example, native or drought tolerant species). Consider design feamres such as: - Using mulches (such as wood chips or bar) in planter areas without ground cover to minimize sediment in runoff - InstalUng appropriate plant materials for the location, in accordance with amount of sunlight and climate, and use native plant materials where possible and/or as recommended by the landscape architect - Leaving a vegetative barrier along the property boundaiy and interior watercourses, to act as a pollutant filter, where appropriate and feasible - Choosing plants that minimize or eHminate the use of fertilizer or pesticides to sustain growth • Employ other comparable, equaUy effective methods to reduce irrigation water ranoff Redeveloping Existing Installations Various jurisdictional stomiwater management and mitigation plans (SUSMP, WQMP, etc.) define "redevelopment" in ternis of amounts of additional impervious area, increases in gross floor area and/or exterior construction, and land disturbing activities with stmctural or impervious surfaces.

Design and Sizing Guidelines • Tlie bioretention area shoiUd be sized to capture the design stomi runoff. • In areas where the native soU permeabUity is less than 0.5 in/hr an miderdrain should be provided. • Recommended minimum dimensions are 15 feet by 40 feet, although the prefened width is 25 feet. Excavated depth should be 4 feet. • Area should drain completely withm 72 hours. • Approximately 1 tree or shrab per 50 ft= of bioretention area should be included. • Cover area with about 3 inches of mulch. Construction/Inspection Considerations Bioretention area shoiUd not be estabhshed until contributing watershed is stabflized. Performance Bioretention removes stonnwater pollutants through physical and biological processes, including adsorption, filtration, plant uptake, microbial acti\ity, decomposition, sedimentation and volatUization (EPA, 1999). Adsorption is the process whereby particulate poUutants attach to soU (e.g., clay) or vegetation surfaces. Adequate contact time bet\veen the surface and poUutaiit must be provided for in the design of the system for this removal process to occur. Thus, the infiltration rate ofthe soUs must not exceed those specified in fhe design criteria or pollutant removal may decrease. PoUutants removed by adsorption indude metals, phosphonis, and hydrocai'bons. FUtration occms as runoff passes through the bioretention ai'ea media, such as the sand bed, gromid cover, and planting soil. Coinmon particulates removed from stomiwater uiclude particulate organic matter, phosphonis, and suspended soHds. Biological processes that occur in wetiands result in poUutaiit uptake by plants and microorganisms in the soU. Plant gi-owth is sustained by die uptake of nutrients from the soUs, wth woody plants locking up these nutiients tlirougli die seasons. Microbial activity within the soU also contributes to the removal of nitrogen and organic matter. Nitrogen is removed by nitiifyiiig and derdtrifymg bacteria, while aerobic bacteria are responsible for die decomposition ofthe organic matter. Microbial processes require oxygen and can result in depleted oxygen levels if die bioretention area is not adequately 2 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Bioretention TC-32 Description The bioretention best management practice (BMP) functions as a soU and plant-based filtration device that removes poUutants through a variety of physical, biological, and diemical ti'eatinent processes. These fadlities normally consist of a grass buffer strip, sand bed, ponding area, organic layer or mulch layer, planting soU, and plants. The nmoff s velocity is reduced by passmg over or through buffer strip and subsequentiy distributed evenly along a ponduig area. Exfiltration of die stored water in the bioretention area planting soU mto the underlying soUs occurs over a period of days. California Experience None documented. Bioretention has been used as a stomiwater BMP since 1992. hi addition to Prince George's Comity, MD and Alexandiia, VA, bioretention has been used successfiiUy at m-ban and suburban areas in Montgomery County, MD; Baltimore County, MD; Qiesterfield County, VA; Prince WiUiani County, VA; Sniitii Mountain Lake State Park, VA; and Gary, NC. Advantages • Bioretention provides stormwater treatment that enhances the quaHty of downstream water bodies by temporarily storing ranoff in the BMP and releasing it over a period of four days to the receiving water (EPA, 1999). • Tlie vegetation provides shade and wind breaks, absorbs noise, and improves an area's landscape.

Sedimentation occurs in the swale or ponding area as the velocity slows and solids faU out of suspension. Tlie removal effectiveness of bioretention has been studied during field and laboratory studies conducted by the University- of Maryland (Davis et al, 1998). During tiiese experiments, synthetic stormwater ranoff was pumped through several laboratoiy 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 Hiosphorus 70-83% Metals (Cu, Zn, Pb) 93-98% TKN 68-80% Total Suspended Solids go?i Organics 90% Bacteria 90% Results for both the laboratoty and field experiments were simUar for each ofthe poUutants analyzed. Doubling or hal\ing the influent poUutant levels had Httle effect on die effluent poUutants concentrations (Da\is et al, 1998). Tlie microbial activity and plant uptake occurring in the bioretention area wUl Hkely result in higher removal rates than those determined for infUtration BMPs. Siting Criteria Bioretention BMPs are generaUy used to treat stonnwater from impervious surfaces at commercial, residential, and industrial areas (EP.A, 1999). Implementation of bioretention for stonnwater management is ideal for median strips, parking lot islands, and swales. Moreover, the ranoff m these areas can be designed to either divert dfrectly into the bioretention area or convey into the bioretention area by a curb and gutter collection system. Tlie best location for bioretention areas is upland fi-om uilets that receive sheet flow ft-om graded areas and at areas that wiU be excavated (EPA, 1999). In order to maximize ti-eatment effectiveness, the site must be graded in such a way that minimizes erosive conditions as sheet flow is conveyed to the treatinent area. Locations where a bioretention area can be readily incorporated into the site plan without further enviromnental damage are preferred. Furtlieraiore, to effectively nunimize sediment loading iu the treatinent ai-ea, bioretention only should be used in stabiHzed drainage areas. January 2003 California Stormwater BMP Handbook New Development and Redevelopment www.cabmphandbooks.com 3 of 8 TC-32 Bioretention Additional Design Guidelines Tlie layout of die bioretention area is deteimined after site constraints such as location of UtUities, underlying soUs, existing vegetation, and drainage are considered (EPA, 1999). Sites with loamy sand soils are espedaUy appropriate for bioretention because the excavated soU can be backfilled and used as the planting soU, dius eliminating the cost of impoi-ting planting soil. Tlie use of bioretention may not be feasible given an mistable surrounding soU stratum, soils with clay content greater than 25 percent, a site with slopes greater than 20 percent, and/or a site witii 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 betiveen 0.1 and 0.4 hectares (0.25 and 1.0 acres). Lai-ger drainage areas may require imdtiple bioretention aieas. Furthemiore, the maxinium drainage area for a bioretention area is determuied by the expected raiufaU intensity- and nmoff' rate. StabUized areas may erode when velocities are greater than 5 feet per second (1.5 meter per second). Tlie designer should detennine die potential for erosive conditions at tiie site. Tlie size ofthe bioretention area, which is a ftmction of the drainage ai-ea and the runoff generated from the area is sized to capture the water quality volume. The recommended minimum dimensions of tiie bioretention area ai-e 15 feet (4.6 metei-s) wide by 40 feet (12.2 meters) long, where die mumnum width allovre enough space for a dense, randonJy-distributed area of trees and shrabs to become established. Thus repHcating a natm-al forest and creating a microcHniate, thereby enabluig the bioretention ai-ea to tolerate the effects of heat sti-ess, acid rain, rmioff pollutants, and insect and disease infestations which landscaped areas in urban settings typicaUy are unable to tolerate. The prefened width is 25 feet (7.6 meters), with a length of twice the width. Essentially, any facihties wider than 20 feet (6.1 meters) should be twice as long as they are wide, wliich promotes the distribution of flow and decreases the chances of concentrated flow. In order to provide adequate storage and prevent water fe-om standing for excessive periods of time the ponding depth of fhe 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. Fmthennore, if water is left standing for longer tiian 72 hours mosquitoes and other insects may start to breed. Tlie appropriate planting soU should be backfiUed 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. GeneraUy the soU should have infiltration rates gi-eater than 0.5 indies (1.25 centimeters) per hour, which is typical of sandy loams, loamy sands, or loams. The pH of the soU should range between 5.5 and 6.5, where poUutants such as organic nitrogen and pliosphoras can be adsorbed by the soU and nucrobial activity can flourish. Additional requirements for the plantuig soil include a 1.5 to 3 percent organic content and a maximum 500 ppni concentration of soluble salts. 4 of 8 California Stormwater BMP Handbook January 2003 New Development and Redevelopment wvw.cabmphandbooks.com Bioretention TC-32 Soil tests should be performed for eveiy 500 cubic yards (382 cubic meters) of planting soU, witii the exception of pH and orgaiuc content tests, which are required oiUy once per bioretention area (EPA, 1999). Planting soil should be 4 inches (10.1 centimeters) deeper than the bottom of die largest root ball and 4 feet (1.2 meters) altogether. Tliis depth will provide adequate soU for die plants' root systems to become estabhshed, prevent plant damage due to severe wind, and provide adequate moisture capacity. Most sites will require excavation in order to obtain the recommended depdi. Planting soU depths of greater than 4 feet (1.2 meters) may require additional consti-uction practices such as shoring measures (EPA, 1999)- Planting soU should be placed in 18 mches or greater Hfts and liglitly compacted until die 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. Tiiree species each of both trees and shi-ubs are recommended to be planted at a rate of 2500 trees and shrabs per hectare (1000 per acre). For uistance, 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 slimbs. The shrab-to-tree ratio should be 2:1 to 3:1. Trees and shrabs should be planted when conditions are favorable. Vegetation should be watered at the end of each day for fourteen days foUowing its planting. Plant spedes tolerant of poUutant loads and varying wet and dry conditions shoidd be used ui die bioretention area. The designer should assess aesthetics, site layout, and maintenance requirenients when selecting plant species. Adjacent non-native mvasive spedes should be identified and die designer should take measm-es, such as providing a soU breach to elinunate the threat of these species invaduig the bioretention area. Regional landscaping manuals should be consulted to ensure that the planting of the bioretention ai-ea meets the landscaping requfrements estabhshed by die local autiioiities. The designers should evaluate die best placement of vegetation witiun the bioretention area. Plants should be placed at inegular intervals to replicate a natural forest. Trees should be placed on the perimeter of the area to provide shade and shelter from die wind. Trees and shrubs can be shdtered from damaging flows if tiiey are placed away from die path of the uicoming nmoff. In cold dimates, spedes that are more tolerant to cold winds, such as evergreens, should be placed in Avindier areas of die site. FoUowing placement ofthe trees and shrabs, the ground cover and/or mulch should be established. Ground cover such as grasses or legumes can be planted at the begiiming 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-avaUable fine shredded hardwood mulch or shredded hardwood chips should be applied to the bioretention area to protect from erosion. Maintenance Tlie primary maintenance requirement for bioretention areas is diat of inspection and repair or replacement of the treatment ai-ea's components. GeneraUy, tius 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 ceU. Appropriately selected plants will aide in redudng fertilizer, pesticide, water, and overall maintenance requirenients. Bioretention system components should blend over time through plant and root growth, organic decomposition, and fhe development of a natural January 2003 California Stormwater BMP Handbook 5 of 8 New Development and Redevelopment www.cabmphandbooks.com TC-32 Bioretention soU horizon. Tiiese biologic and physical processes over time will lengtiien the facUity's life span and reduce the need for extensive maintenance. Routine maintenance should indude a biannual health evaluation of the trees and slirubs and subsequent removal of any dead or diseased vegetation (EPA, 1999). Diseased vegetation should be ti-eated as needed using preventative and low-toxic measures to die extent possible. BMPs have the potential to create very attractive habitats for mosquitoes and other vectors because of highly organic, often lieavUy vegetated areas nfrxed witii shallow water. Routine inspections for areas of standing water within tiie BMP and corrective measures to restore proper infiltration rates are necessaiy to prevent creating mosquito and other vector habitat. In addition, bioretention BMPs are susceptible to invasion by aggressive plant species such as cattails, wliich increase the chances of water standing and subsequent vector production if not routinely maintained. In order to maintain fhe treatment area's appearance it may be necessary to prane and weed. Furthemiore, mulch replacement is suggested when erosion is evident or when the site begins to look uiiatti-active. Spedfically, the entire area may require mulch replacement every two to tiiree yeai-s, although spot mulching may be suffident when there are random void ai-eas. Mulch replacement should be done prior to the start of the wet season. New Jersey's Departinent of Environmental Pi-otection states in thefr bioretention systems standards that accumulated sedunent and debris removal (especiaUy at the inflow point) will nomiaUy be the primaiy maintenance function. Other potential tasks include replacement of dead vegetation, soU pH regulation, erosion repair at inflow points, mulch replenishment, unclogguig the underdrain, and repairing overflow structures. There is also the possibflity that the cation exchange capacity of the soUs in the ceU wiU be sigmficaiitly reduced over time. Depending on poUutant loads, soUs may need to be replaced wtliiii 5-10 years of construction (LID, 2000). Cost Construction Cost Constmction cost estimates for a bioretention ai-ea ai e slightly greater than those for the required landscapuig for a new development (EPA, 1999). A general rale of thumb (Coffinan, 1999) is that residential bioretention ai-eas average about $3 to $4 per square foot, depending on soU conditions and the density and types of plants used. Conmiercial, industiial and instimtional site costs can range between $10 to $40 per square foot, based 011 the need for control sti-uctiu-es, curbing, storm drains and underdrains. Retrofittmg a site typically costs more, averaguig $6,500 per bioretention ai-ea. Tlie higher costs are attributed to the demolition of existing concrete, asphalt, and existing stractm-es and the replacement of fiU material with planting soU. Tlie costs of retrofitting a conmiercial site m Maryland, Kettering Development, witii 15 bioretention areas were estunated at $111,600. In any bioretention ai ea design, the cost of plants varies substantiaUy and can account for a significant portion of the expenditures. WliUe diese cost estimates are sHghtiy greater than tiiose of typical landscaping treatment (due to the increased number of plantings, additional soU excavation, backfUl material, use of underdiains etc.), those landscaping expenses that would be required regardless ofthe bioretention installation should be subtracted \vhen determining the net cost. 6 of 8 California Stormwater BMP Handbook January 2003 New Developrnent and Redevelopment www.cabmphandbooks.com Bioretention TC-32 Perhaps of most importance, however, the cost savings compared to the use of traditional stractiiral stomiwater conveyance systems makes bioretention areas quite attractive financially. For example, the use of bioretention can decrease the cost required for consti-ucting stormwater conveyance systems at a site. A medical office building in Maryland was able to reduce the aniomit of stonn 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 approxunately $100,000 using bioretention ceUs on each lot instead of nearly $400,000 for the traditional stomiwater ponds that were origmally plaimed (Rappahanock,). Also, m residential areas, stonnwater management controls become a part of each property owner's landscape, reducmg the public burden to mauitaiii large centralized facUities. Maintenance Cosf Tlie operation and manitenance costs for a bioretention facihty wiU be comparable to diose of typical landscaping required for a site. Costs beyond the nomial landscaping fees wUl include the cost for testing the soUs and may include costs for a sand bed and planting soU.

In the City of Carlsbad, storm drains flow directiy into local creeks, lagoons and the ocean without treatment. Storm water pollution is a serious problem for our natural environment and for people who live near streams or wetlands. Storm water pollution comes from a variety of sources Including oil, fuel, and fluids, from vehicles and heavy equipments, pesticide runoff from landscaping, and from materials such as concrete and mortar from construction activities. The City of Carlsbad is committed to improving water quality and reducing the amount of pollutants that enter our precious waterways. A Clean Environment is Important to All of UsI City of Carlsbad 1635 Faraday Avenue Carisbad, CA 92008 Storm Water HOTIine: 760-602-2799 stormwater@ci.carlsbad.ca.us March 2003 nly Rain in the Storm Drain! Pollution Prevention is up to YOU! Did you know that storm drains are NOT connected to sanitary sewer systems or treatment plants? The primaty purpose of storm drains is to carry rainwater away from developed areas to prevent flooding. Untreated pollutants MISQBBQi such as concrete and mortar flow directly into creeks, lagoons and the ocean and are toxic to fish, wildlife, and the aquatic environment. Disposing of these materials into storm drains causes serious ecological problems—and is PROHIBITED by law. Do the Job Right! This brochure was designed for do-it- yourself remodelers, homeowners, masons and bricklayers, contractors, and anyone else who uses concrete or mortar to complete a construction project. Keep storm water protection in mind whenever you or people you hire work on your house or property. STORM WATER HOTLINE 760-602-2799 Best Management Practices Best Management Practices or BMPs are procedures and practices that help to prevent pollutants such as chemicals, concrete, mortar, pesticides, waste, paint, and other hazardous materials from entering our storm drains. All these sources add up to a pollution problem. But each of us can do our part to keep storm water clean. These efforts add up to a pollution solution! What YOU Can Po: • Set up and operate small mixers on tarps or heavy plastic drop cloths. • Don't mix up more fresh concrete or mortar than you will need for a project. • Protect applications of fresh concrete and mortar from rainfall and runoff until the material has dried. • Always store both dry and wet materials under cover, protected from rainfall and runoff and away from storm drains or waterways. • Protect dry materials from wind. Secure bags of concrete mix and mortar after they are open. Don't allow dty products to blow into driveways, sidewalks, streets, gutters, or storm drains. • Keep all construction debris away from the street, gutter and storm drains. Never dispose of washout into the street, storm drains, landscape drains, drainage ditches, or streams. Empty mixing containers and wash out chutes onto dirt areas that do not flow to streets, drains or waterways, or allow material to dty and dispose of properly. Never wash excess material from bricklaying, patio, driveway or sidewalk construction into a street or storm drain. Sweep up and dispose of small amounts of excess dty concrete, grout, and mortar in the trash. Wash concrete or brick areas only when the wash water can flow onto a dirt area without further runoff or drain onto a surface which has been bermed so that the water and solids can be pumped off or vacuumed up for proper disposal. Do not place fill material, soii or compost piles on the sidewalk or street. If you or your contractor keep a dumpster at your site, be sure it is securely covered with a lid or tarp when not in use. During cleanup, check the street and gutters for sediment, refuse, or debris. Look around the corner or down the street and clean up any materials that may have already traveled away from your property.

What's the problem with fertilizers and pesticides? Fertilizer isn't a problem—IF ifs used carefully. If you use too much fertilizer or apply it at the wrong time, it can easily wash off your lawn or garden into storm drains and then flow untreated into lakes or streams. Just like in your garden, fertilizer in lagoons and streams makes plants grow. In water bodies, extra fertilizer can mean extra algae and aquatic plant growth. Too much algae harms water quality and makes boating, fishing and swimming unpleasant. As algae decay, they use up oxygen In the water that fish and other wildlife need.

Instead of watering for 15 minutes straight, break up the session into 5 minute intervals alkiwing water to soak in before the next application. Keep irrigation systems well- maintained and water only when needed to save money and prevent over-watering. Use fertilizers and pesticides sparingly. Have your soil tested to determine the nutrients needed to maintain a healthy lawn. Consider using organic fertilizers— they release nutrients more slowly. Leave mulched grass clippings on the lawn to act as a natural fertilizer. • Use pesticides only when absolutely necessary. Use the least toxic product intended to target a specific pest, such as insecticidal soaps, boric acid, etc. Always read the label and use only as directed. • Use predatory insects to control harmful pests when possible. • Properly dispose of unwanted pesticides and fertilizers at Household Hazardous Waste collection facilities.

How can YOU help keep our environment clean? Oil does not dissolve in water. It lasts a long time and sticks to everything from beach sand to bird feathers. Oil and other petroleum products are toxic to people, wildlife and plants. One pint of oil can make a slick larger than a football field. Oil that leaks from our cars onto roads and driveways is washed into storm drains, and then usually flows directly to a creek or lagoon and finally to the ocean. Used motor oil is the largest single source of oil pollution in our ocean, creeks and lagoons. Americans spill 180 million gallons of used oil each year into our waters. This is 16 times the amount spilled by the Exxon Valdez in Alaska. Having a clean environment is of primary importance for our health and economy. Clean waterways provide commercial opportunities, recreation, fish habitat and add beauty to our landscape. YOU can help keep our ocean, creeks and lagoons clean by applying the following tips: •Stop drips. Check for oil leaks regularly and fix them promptly. Keep your car tuned to reduce oil use. • Use ground cloths or drip pans beneath your vehicle if you have leaks or are doing engine work. • Clean up spills immediately. Collect all used oil in containers with tight fitting lids. Do not mix different engine fluids. • When you change your oil, dispose of it properly. Never dispose of oil or other engine fluids down the storm drain, on the ground or into a ditch. • Recycle used motor oil. There are several locations in Carisbad that accept used motor oil. For hours and locations, call 760-434-2980. • Buy recycled ("refined") motor oil to use in your car. 1* A clean environment is important to all of us!

Improperly disposing of swimming pool and spa water into storm drains may be harmful to the environment. Best Management Practices Best Management Practices or BMPs are procedures that help to prevent pollutants like chlorine and sediment from entering our storm drains. Each of us can do our part to keep storm water clean. Using BMPs adds up to a pollution solution! How Do I Get Rid of Chlorine? Pool and spa water may be discharged to the storm drain if it has been properly dechlorinated and doesn't contain other chemicals. The good news is that chlorine naturally dissipates over time. Monitor and test for chlorine levels in the pool over a period of 3 to 5 days. Drain the water before algae starts to grow. Consider hiring a professional pool service company to clean your pool, fountain, or spa and make sure they dispose of thc water and solids properly. For more information about discharging wastewater to the sanitary sewer, please contact the Encina Wastewater Authority at (760)438- 3941. Before you discharge your swimming pool or spa water to thc storm drain, thc water: • Must not contain chlorine, hydrogen peroxide, acid, or any other chemicals. • Can not carry debris or vegetation. • Should have an acceptable pH of 7-8. • Can not contain algae or harmful bacteria (no "green" present). • Flow must be controlled so that it does not cause erosion problems. Pool Filters Clean filters over a lawn or other landscaped area where the discharge can be absorbed. Collect materials on filter cloth and dispose into the trash. Diatomaceous earth cannot be discharged into the street or storm drain systems. Dry it out as much as possible, bag it in plastic and dispose into the trash. Acid Washing Acid cleaning wash water is NOT allowed into thc storm drains. Make sure acid washing is done in a proper and safe manner that is not harmful to people or the environment. It may be discharged into the sanitary sewer through a legal sewer connection after the pH has been adjusted to no lower than 5.5 and no higher than 11. Do the Job Right! • Use thc water for irr igation. Try draining de-chlorirrated pool water gradually onto a landscaped area. Water discharged to landscape must not cross property lines and must not produce runoff. • Do not use copper-based algaecides. Control algae with chlorine or other alternatives to copper-based pool chemicals. Copper is harmful to thc aquatic environment. • During pool construction, contain ALL materials and dispose of properly. Materials such as cement, Gunite, mortar, and sediment must not be discharged into the storm drains.

In the City of Carlsbad, storm drains flow directly into local creeks, lagoons and the ocean without treatment. Storm water pollution is a serious problem for our natural environment and for people who live near streams or wetlands. Storm water pollution comes from a variety of sources including oil, fuel, and fluids, from vehicles and heavy equipments, pesticide runoff from landscaping, and from materials such as concrete and mortar from construction activities. The City of Carlsbad is committed to improving water quality and reducing the amount of pollutants that enter our precious waterways.

Pollution Prevention is up to YOU! Did you know that storm drains are NOT connected to sanitary sewer systems or treatment plants? The primary purpose of storm drains is to carry rainwater away from developed areas to prevent flooding. Untreated pollutants such as concrete and mortar flow directly into creeks, lagoons and the ocean and are toxic to fish, wildlife, and the aquatic environment. Disposing of these materials into storm drains causes serious ecological problems—and is PROHIBITED by law. Do the Job Right! This brochure was designed for do-it- yourself remodelers, homeowners, masons and bricklayers, contractors, and anyone else who uses concrete or mortar to complete a construction project. Keep storm water protection in mind whenever you or people you hire work on your house or property. STORM WATER HOTLINE 760-602-2799 Best Management Practices Best Management Practices or BMPs are procedures and practices that help to prevent pollutants such as chemicals, concrete, mortar, pesticides, waste, paint, and other hazardous materials from entering our storm drains. All these sources add up to a pollution problem. But each of us can do our part to keep storm water clean. These efforts add up to a pollution solution! What YOU Can Do: • Set up and operate small mixers on tarps or heavy plastic drop cloths. • Don't mix up more fresh concrete or mortar than you will need for a project. • Protect applications of fresh concrete and mortar from rainfall and runoff until the material has dried. • Always store both dry and wet materials under cover, protected from rainfall and runoff and away from storm drains or waterways. • Protect dry materiais from wind. Secure bags of concrete mix and mortar after they are open. Don't allow dry products to blow into driveways, sidewalks, streets, gutters, or storm drains. • Keep all construction debris away from the street, gutter and storm drains. Never dispose of washout into the street, storm drains, landscape drains, drainage ditches, or streams. Empty mixing containers and wash out chutes onto dirt areas that do not flow to streets, drains or waterways, or allow material to dry and dispose of properly. Never wash excess material from bricklaying, patio, driveway or sidewalk construction into a street or storm drain. Sweep up and dispose of small amounts of excess dry concrete, grout, and mortar in the trash. Wash concrete or brick areas only when the wash water can flow onto a dirt area without further runoff or drain onto a surface which has been bermed so that the water and solids can be pumped off or vacuumed up for proper disposal. Do not place fill material, soil or compost piles on the sidewalk or street. If you or your contractor keep a dumpster at your site, be sure it is securely covered with a lid or tarp when not in use. During cleanup, check the street and gutters for sediment, refuse, or debris. Look around the corner or down the street and clean up any materials that may have already traveled away from your property.

What's the problem with fertilizers and pesticides? Fertilizer isn't a problem—IF it's used carefully. If you use too much fertilizer or apply it at the wrong time, it can easily wash off your lawn or garden into storm drains and then flow untreated into lakes or streams. Just like in your garden, fertilizer in lagoons and streams makes plants grow. In water bodies, extra fertilizer can mean extra algae and aquatic plant growth. Too much algae harms water quality and makes boating, fishing and swimming unpleasant. As algae decay, they use up oxygen in the water that fish and other wildlife need.

Dont over irrigate. Use drip irrigation, soaker hoses or micro- ^ray system and water early in the morning. ilf:]^ have a spray head sprinkler ^^^ilg^em, consider adjusting your i^il^ering method to a cycle and soak. Instead of watering for 15 minutes straight, break up the session into 5 minute intervals albwing water to soak in before the next application. 4 Keep irrigation systems well- maintained and water only when needed to save money and prevent over-watering. Use fertilizers and pesticides sparingly. Have your soil tested to determine the nutrients needed to maintain a healthy lawn. Consider using organic fertilizers— they release nutrients more slowly. Leave mulched grass clippings on the lawn to act as a natural fertilizer. Use pesticides only when absolutely necessary. Use the least toxic product intended to target a specific pest, such as insecticidal soaps, boric acid, etc. Always read the label and use only as directed. Use predatory insects to controi harmful pests when possible. Properly dispose of unwanted pesticides and fertilizers at Household Hazardous Waste collection facilities.

Did you know that storm drains are NOT connected to sanitary sewer systems and treatment plants? The primary purpose of storm drains is to carry rainwater away from developed areas to prevent flooding. Untreated storm water and the pollutants it carries, flow directly into creeks, lagoons and the ocean. In recent years, sources of water pollution like industrial waters from factories have been greatly reduced. However now, the majority of water pollution occurs from things like cars leaking oil, fertilizers from farms, lawns and gardens, failing septic tanks, pet waste and residential car washing into the storm drains and into the ocean and waterways. All these sources add up to a pollution problem! But each of us can do small things to help clean up our water and that adds up to a pollution solution!

How can YOU help keep our environment clean? Oil does not dissolve in water. It lasts a long time and sticks to everything from beach sand to bird feathers. Oil and other petroleum pnDducts are toxic to people, wildlife and plants. One pint of oil can make a slick larger than a football field. Oil that leaks from our cars onto roads and driveways is washed into storm drains, and then usually flows directly to a creek or lagoon and finally to the ocean. Used motor oil is the largest single source of oil pollution in our ocean, creeks and lagoons. Americans spill 180 million gallons of used oil each year into our waters. This is 16 times the amount spilled by the Exxon Valdez in Alaska. Having a clean environment is of primary importance for our health and economy. Clean watenways provide commercial opportunities, recreation, fish habitat and add beauty to our landscape. YOU can help keep our ocean, creeks and lagoons clean by applying the following tips: • Stop drips. Check for oil leaks regularly and fix them promptly. Keep your car tuned to reduce oil use. • Use ground cloths or drip pans beneath your vehicle if you have leaks or are doing engine work. • Clean up spills immediately. Collect all used oil in containers with tight fitting lids. Do not mix different engine fluids. • When you change your oil, dispose of it properly. Never dispose of oil or other engine fluids down the storm drain, on the ground or into a ditch. • Recycle used motor oil. There are several locations in Carlsbad that accept used motor oil. For hours and locations, call 760-434-2980. • Buy recycled ("refined") motor oil to use in your car.

The purpose of the test was to determine the rate at which water was able to pass through the filter media which could then serve as the bases for determining the flow capacity ofthe PURESTREAM system. Testing Methodologv The test was conducted using a 4" diameter clear acrylic cylinder which was open at both ends. A screen was secured to the bottom of the cylinder, which allowed the cylinder to be filled with 12" of gravel and 18" of Katchall mixed media. A layer of Katchall filtration fabric was placed at the bottom of the gravel layer, between the gravel layer and the mixed media and at the top of the mixed media. This configuration of gravel and filter media is equivalent to the filter media in the Katchall PURESTREA\f Model 6-4-42 vault. The length of the test tube resuhed in 6" of freeboard to introduce water to the top ofthe filter media. A gallon of water was poured through the flow test devise and the time was recorded when there was no longer any standing water above the filter media. A total of four flow tests were conducted, one when the filter media was dry and three after the filter media had been wetted. A summary of the testing protocol methods and the test results are attached to this report. Results and Summarv Based the tests that were conducted, it was observed that the Katchall Bio-Filtration System had a flow capacity of 0.0065 cubic feet per second (2.922 gallon per minute) per square foot of filter media surface area. The dry filter media had a flow capacity of 0.0039 cubic feet per second (1.765 gpm) per square foot of filter media surface area, with the flow rate increasing as the filter media became wetted. 38248 POTATO CANYON RD., OAK GLEN. CALIFORNIA 92399 TELEPHONE (909)864-3180 • FAX (909) 864-0850 Over a surface area of one square foot, the wetted filtration media will pass 281.8" of water per hour. A summary of the test results is attached. If you should have any additional questions regarding this report, please feel free to contact us at your convenience. Sincerely SITETECH, Inc. Bemhard K. Mayer, P.E. FOR REFERENCE ONLY Test Protocols - Katchall Miied Media Configuration of testing devise and materials: A tube was mounted in a vertical position on a 1 '/2-inch steel pole with an 8" x 8" solid base. The tube was placed 12-inches above the base to allow sufficient space for water collection. The configuration of the tesfing devise was as follows: • The tube is a 4-inch (ID) clear acrylic tube 36-inches in length • A screen with %-inch openings was secured to bottom of tube with a hose clamp • One (1) 4-inch circular layer of Katchall filtration fabric was placed on top of screen • 12-inches of %-inch minus washed gravel was placed on top of screen/fabric • A single 4-inch diameter circular layer of Katchall Filtration fabric was placed on top of gravel bed • 18-inches of Katchall Mixed Media was positioned on top of single filtration fabric • Another single layer of 4-inch diameter filtration fabric was positioned on top ofthe Mixed Media • A single piece of screen ('/4-inch openings) was placed approximately 4-inches above the upper-most single layer of filtration fabric • 6-inches of free-board area was left at the top ofthe tube FOR REFERENCE ONLY FOR REFERENCE ONLY Dry Materials Test - Test #1 To more accurately demonstrate flows capacities ofthe system when the Mixed Media has not experienced any flows for an extended period, we utilized dry Katchall Mixed Media for the first test, simulating the first rain event ofa season. One (1) gallon of water was poured into the top ofthe 4-inch tube With dry materials, it took 6 min. 30 sec. (390 sec.) for the 1-gallon to be absorbed / pass through the filter media. The time was noted when there was no longer any standing water above the filter media. Summation Flow Rate 1-Gallon of clear water processing through .218 cubic feet of dry Katchall Mixed Media in 390 seconds Wet Materials Tests - Test #2. #3 and #4 To determine what flow-rates would occur after an initial quantity of water had been introduced to the filter media, we repeated the above procedures, using the wetted Katchall Mixed Media generated by Test # 1. This test was repeated three times: Test #2 With wetted materials, it took 3 min. 52 sec. (232 sec.) for the 1-gallon to be absorbed / pass through the filter media. The time was noted when there was no longer any standing water above the filter media. Test #3 With wetted materials, it took 3 min. 50 sec. (230 sec.) for the 1-gallon to be absorbed / pass through the filter media. The time was noted when there was no longer any standing water above the filter media. Test #4 With wetted materials, it took 3 min. 55 sec. (235 sec.) for the I-gallon to be absorbed / pass through the filter media. The time was noted when there was no longer any standing water above the filter media. FOR REFERENCE Summation ONLY Flow Rate 1-Gallon of clear water processing through .218 cubic feet of wetted Katchall Mixed Media in a maximum of 235 seconds. This value was used for determining the flow rate ofthe filter media. aiJIImCll I _ _ _^ _ __CIVIL ENGINEERING ' SURVEYING ' PLANNING ENG/NEERS oa2o AIRPORT DRIVE.

Brief Explanation of Design - Sizing Criteria Katchall designs all of their products to provide positive filtration of discharges from extended rain events, exceeding those ofthe typical "first-flush" volumes, typically accommodating rain events exceeding QIO. Katchall PURESTREAM BioFiitration Chambers incorporate a separate high-flow bypass area, eliminating the need for secondary inlet structures. This area provides filtration for all discharges entering the vault when they exceed the mixed media area's capability to absorb - filter them during heavy rain events, i.e, QIO - Q25 and QIOO. Site - Svstem(s) Recommendation(s) To more fully utitize the designed capabilities of the Katchall PURESTREAM BioFiitration Chambers and potentially reduce the volume of un-fi!tered njnoff discharging directly onto Magnolia Avenue, we recommend the use of one (1) of the PURESTREAM 600 Series, specifically the Model # 6-4-42, and one (1) of the PURESTREAM 800 series, specifically the Model # 8-4-4. Limitations The calculations contained herein are for analyzing the capacities forthe "first-flush" and there is no implication that the Katchall PURESTREAM Vaults have the requirement to capture any flows above those stated in the calculations. The catchbasins are "flow-by" and wifl be utilized as such; allowing excess flows the option of following the above ground watercourse shown on the improvement plans. The high-flow bypass in the Katchall vaults Is purely an additional option, and is not required in this condition. Please see the attached sheet for the flowrate calculations. adkan ENG/NEERS CALCULATIONS BMP Area 1 - Katchall PURESTREAM Model 8-4-4 6-inch Thick Reinforced Concrete Base, Walls and Top Cover CIVIL ENGINEERING • SURVEYING • PLANNING 6820 AIRPORT DRIVE.

Titles 20 and 21 of the Carlsbad Municipal Code, and the State Subdivision Map Act, and will not cause serious public health problems, in that the 9 project is consistent with all requirements of the General Plan and Titles 20 and 21 governing subdivisions and the design of planned developments. 10 That the proposed project is compatible with the surrounding future land uses since 11 surrovmding properties are designated for residential and open space development on the General Plan, in that the proposed project consists of open space and 53 airspace condominium units at densities similar and compatible with the surrounding 13 residential land uses. 14 3. That the site is physically suitable for the type and density of the development since the site is adequate in size and shape to accommodate residential development at thc density 15 proposed, in that all required development standards and design criteria required by the applicable zoning standards are incorporated into the project without the need for variances from development standards. 17 That the design of the subdivision or the type of improvements will not conflict with 18 easements of record or easements established by court judgment, or acquired by the public at large, for access through or use of property within the proposed subdivision, in that the project has been designed and conditioned such that there are no conflicts with established easements. 2j 5. lliat the property is not subject to a contract entered into pursuant to the Land Conservation Act of 1965 (Williamson Act), 22 That the design of the subdivision provides, to the extent feasible, for future passive or 23 natural heating or cooling opportunities in the subdivision, in that structures are oriented in a manner that allows for solar exposure and will take advantage of shade and receive prevailing breezes. 25 7. That the Planning Commission has considered, in connection with the housing proposed 26 ''y subdivision, the housing needs of the region, and balanced those housing needs against the public service needs of the City and available fiscal and environmental 27 resources. 28 8. That the design of the subdivision and improvements are not likely to cause substantial environmental damage nor substantially and avoidably injure fish or wildlife or their PC RESO NO. 6058 -2- habitat, in that the proposed development will impact 4.4 acres of Coastal Sage Scrub, 0.5 acres of Southern Maritime Chaparral and 0.03 acres of Waters of the U.S. The project will mitigate for all impacted habitats, in compiiance with the City of Carlsbad HMP. Upland habitat [Coastal Sage Scrab (including all sub associations), and Southern Maritune Chaparral] mitigation requires a '•no net loss standard" and will typically consist of creation of the habitat being impacted (or substantial restoraticm where allowed) at a ratio of at least 1:1 as provided in the HMP. Substantial restoration of the highly degraded areas (where effective functions of the habitat type have been lost) may be substituted for creation subject to the consultation and concurrence of USFWS, CDFG, and the City of Carlsbad. The remaining mitigation requirement will be satisfied through the purchases in a g mitigation bank. Impacts to the unvegetated Waters of the U.S. shall be satisfied through the purchase in a suitable mitigation bank due to lack of restoration 9 opportunities on site, and the project is not unpacting vegetative wetlands. 10 9. That the discharge of waste from the subdivision will not result in violation of existing Califomia Regional Water Quality Control Board requurements, in that the project has ^ ^ been designed in accordance with the Best Management Practices for water quality J2 protection in accordance with the City's sewer and drainage standards and the project is conditioned to comply with the National Pollutant Discharge Elimination 13 System (NPDES) requirements. 14 10. The Planning Conunission finds that the project, as conditioned herein, is in confonnance with the Elements of the City's General Plan, based on the facts set forth in ^ ^ the staff report dated April 5,2006, including, but not limited to the following: a. Land Use - The RM and GMCP (6 du/ac), permits 81 residential units, and 17 the project proposes 53 residential units. However, consistent with Program 3.8 of the City's certified Housuig Element, all of the dwelling units, which 18 were anticipated toward achieving the City's share of the regional housing need that are not utilized by developers in approved projects, are deposited into the City's Excess Dwelling Unit Bank. These excess dwelling units are 20 avaUable for allocation to other projects. Accordingly, there is no net loss of residential unit capacity and there are adequate properties identified in the 21 Housing Element allowing residential development with a unit capacity, including second dwelling units, adequate to satisfy the City's share of the regional housing need. Projects are still considered to be consistent with the 22 (ieneral Plan if they are approved at densities below the minimum of the density range. 24 This project proposes 53 condominium units, which is below the density 25 range for the RM General Plan Land Use designation. However, the project application was on file, deemed complete, and considered "in the pipeline" 26 before October 27, 2004, and is exempt from the recently adopted General Plan language which requires any subdivision of land or construction of more than one dwelling to be subject to the minimum density range and 28 intent of the underlying residential land use designation. PC RESO NO. 6058 -3- b. Chculation - The project will take access oti of Dove Lane and the applicant is proposing full street improvements to El Camino Real. On-site circulation consists of a private driveway which will be designed in accordance with City standards. c. Noise - The project is required to constmct a combination of 10-foot-high and 6-foot-high barriers around the southern and eastem portion of the project site. The second floor balcony areas of Buildings 8 through 12 will require 8-foot-high wall/glass barriers to properly mitigate for the future El Camino Real noise levels, and an acoustical analysis to ensure adequate 7 interior noise attenuation to below 45 dBA CNEL will be achieved is required prior to issuance of buUding pennit 8 g d. Housing - The project is consistent with the Housing Element of the General Plan and the Inclusionary Housing Ordinance as the applicant is proposing 10 to enter into an Affordable Housing Agreement to purchase 9 offsite affordable housing credits in the Villa Loma Project. 11 12 11. The project is consistent with the City-Wide Facilities and Improvements Plan, the Local Facilities Management Plan for Zone 21 and all City public facility policies and 13 ordinances. The project includes elements or has been conditioned to construct or provide funding to ensure that all facilities and improvements regarding sewer collection 14 and treatment; water; drainage; circulation; fu-e; schools; parks and other recreational facilities; libraries; government administrative facilities; and open space, related to the project will be installed to serve new development prior to or concunent with need. Specifically, 17 a. The project has been conditioned to provide proof from the Carlsbad Unified School District that the project has satisfied its obligation for school facilities 18 j9 b. Park-in-lieu fees are required by Carlsbad Municipal Code Chapter 20.44, and will be collected prior to issuance of building permit. 20 c. The Public Facility fee is required to be paid by Council Policy No. 17 and will be 21 collected prior to die issuance of building permit. 22 12. The project has been conditioned to pay any increase in public facility fee, or new 23 constmction tax, or development fees, and has agreed to abide by any additional requirements established by a Local Facilities Management Plan prepared pursuant to 24 Chapter 21.90 of the Carlsbad Municipal Code. This will ensure continued availability of public facilities and will mitigate any cumulative impacts created by the project. 25 13. This project has been conditioned to comply with any requu-ement approved as part of the 26 Local Facilities Management Plan for Zone 21. 14. That all necessary public facilities required by the Growth Management Ordinance will 28 be constructed or are guaranteed to be constructed concunently with the need for them created by this project and m compliance with adopted City standards. PC RESO NO. 6058 -4- 8 15. The Planning Commission has reviewed each of the exactions imposed on the Developer contained in this resolution, and hereby finds, in this case, that the exactions are imposed to mitigate impacts caused by or reasonably related to the project, and the extent and the degree ofthe exaction is in rough proportionality to the impact caused by the project.
