Sequencing of stormwater quality implementation relative to land disturbance activities: This plan has been created in an effort to eliminate sediment from leaving the project site during construction protecting the adjoining properties and Carmel Creek. The majority of the existing watershed sheet drains into shallow concentrated flow prior to entering Van Arsdall Legal Drain on the eastern side of the property. See notes on sheets C1.60 -1.61 for sequencing of excavation and pipe installation. PRECONSTRUCTION ACTIVITIES: 1. Call the Indiana Underground Plant Protection systems, Inc. "Holey Moley at 1- 800 382 -5544 to check the location of any existing utilities. They should be notified two working days before construction takes place. 2. Evaluate the site for vegetative areas to be saved. See Grading Utility Plan sheet BP1- C1.30 for more detail. 3. An orange construction fence shall be constructed along the perimeter of the dripline of the tree preservation areas prior to any earth moving as shown on sheet BP1 -C1.40 A silt fence shall be installed at the edges of the project site where there is potential for any stormwater runoff. Potential areas are identified based on existing topography along the perimeters of the site. See sheet BP1 -C1.60 -1.61 5. Evaluate, mark and protect important trees and associated root zones. Evaluate existing vegetation suitable for use as filter strips along the project boundaries. 6. Maintain a 10' minimum grass filter strip along the boundary of roadways where possible. 7. A construction entrance shall be placed per the plan location. 8. Establish construction staging area for equipment and vehicles as detailed on the Grading Utility Plan sheet BP1 -C1.40 for location. 9, Establish onsite location for owner /operator /contractor placement of approved plans and Rule 5 NOI and Rule 5 inspection documentation. ESTABLISH SILT BASIN: 1. Contractor to evaluate location of soil stockpile area and prep with silt fence (see details). 2. Install the primary outfall system for the proposed pond located at the Eastern boundary of the site. Install precast concrete end section silt protection. 3. After completion of the outfall pipe and perforated riser, commence construction of the temporary diversion swales and temporary sediment basin. CONSTRUCTION ACTIVITIES: Once erosion and sediment control measures are in place, begin land clearing followed immediately by rough grading. Do not leave large areas unprotected for more than 15 days. Rule 5 requires that all disturbed areas that potentially will be idle for 15 days or more will be stabilized (seeded, mulched, etc..) immediately. 2. Strip topsoil and temporarily stockpile in location provided on the Stormwater Pollution Prevention Plan Sheets BP -C1.60 -1.61. 3 Perform rough grading. 4. After completion of rough grading, final grade and seed pond banks, landscape berms, common areas and swales immediately after grading is completed. 5. Upon completion of rough grading, install sanitary and storm sewers. As storm sewers are constructed, install inlet protection measures. Install riprap upon completion of end section installation at system discharge. 6. Upon completion of sewer installation and inlet protection, proceed with street construction. 7. Liming of streets should be done prior to the installation of storm sewers to prevent the transmission of lime dust to ponds or receiving waters. 8. Once pavement and curbs are in place, install curb inlet sediment barriers. 9. Once inlet protection is in place, final grade all areas and spread topsoil. Upon completion of all grading, verify depth of pond per plan requirement, dredge as needed. Stable construction entrance location(s) and specifications.

E' Material handling and spill prevention plan: Purpose: The intention of this Spill Prevention, Control and Countermeasures (SPCC) is to establish the procedures and equipment required to prevent the discharge of oil and hazardous substances in quantities that violate applicable water quality standards, cause a sheen upon or discoloration of the surface of navigable waters or adjoining shorelines, or cause sludge or emulsion to be deposited beneath the surface of the water or adjoining shorelines. The Plan also establishes the activities required to mitigate such discharges (i.e., countermeasures) should they occur. Definitions: Pollutant: means pollutant of any kind or in any form, including but not limited to sediment, paint, cleaning agents, concrete washout, pesticides, nutrients, trash, hydraulic fluids, fuel, oil, petroleum, fuel oil, sludge, oil refuse, and oil mixed with wastes other than dredged soil. Discharge: Includes but is not limited to, any spilling, leaking, pumping, pouring, emitting, emptying, or dumping. Navigable Waters: Means all waters of the United States that are connected with a navigable stream, lake, or sea. [Note: This definition is usually interpreted to mean any wastewater (even normally dry wash or storm sewer) that eventually drains into a navigable stream]. Plan Review and Amendements: This Plan shall be reviewed and /or amended, if necessary, whenever there is a change in the design of the site, construction, operation, or maintenance which materially affects the site's potential for the discharge of regulated material AND groundwater contamination. The facility does have city sanitary sewer and city water. E3: Prediction of Potential Spills: 1. Nearest Navigable Water: White River 2. Drainage System: All storm drainage leaves the site by open channel flow to the east to Carmel Creek. 3. Possible Spill Sources (During and post construction): Vehicular sources such as leaking fuel or oil, brake fluid, grease, antifreeze; construction trash and debris, biological agents found in trash and debris, fertilizers, household items including but not limited to cleaning agents, chemicals, paint, herbicides and pesticides. 4. Groundwater Contamination: The facility maintains NO above ground or under ground storage tanks at this site. Therefore, it is felt that there is little or no possibility of post construction groundwater contaimination. Alert Procedures for Spills: 1. Any personnel observing a spill will immediately instigate the following procedure: a.) Dialing "0" from any telephone. b.) Notify the appropriate emergency personnel. 2. The Emergency Coordinator will then take the following actions: a.) Barricade the area allowing no vehicles to enter or leave the spill zone. b Notify the Indiana Department of Environmental Management, Office of Emergency Response by calling the appropriate telephone number Office 317 233 -7745 Toll Free 800- 233 -7745 Also the National Response Center at 800- 424 -8802 and provide the following information: Time of observation of the spill Location of the spill Identity of material spilled Probable source of the spill Probable time of the spill Volume of the spill and duration Present and anticipated movement of the spill Weather conditions Personnel at the scene Action initiated by personnel c.) Notify the local Fire Deportment Phone: 9 -1 -1 d.) Notify the local Police Department Phone: 9 -1 -1 e.) Notify waste recovery contractor, maintenance personnel or other contractual personnel as necessary for cleanup. nil the situation h been and monitor cleanup u t t e s tuat o os Coordinate P stabilized and all spills have been eliminated. Cooperate with the IDEM -OER on procedures and reports involved with the event. 3'l f. 9) Cleanup Parameters: 1. The Developer shall be continually kept informed, maintain lists of qualified contractors and available Vac trucks, tank pumpers and other equipment readily accessible for clean -up operations. In addition, a continually updated list of available absorbent materials and clean -up supplies should be kept on site. 2. All maintenance personnel will be mode aware of techniques for prevention of spills. They will be informed of the requirements and procedures outlined in this plan. They will be kept abreast of current developments or new information on the prevention of spills and or necessary alterations to this plan. 3. When spills occur which could endanger human life and this becomes primary concern, the discharge of the life- saving protection function will be carried out by the local police and fire departments. 4. Absorbent materials, which are used in cleaning up spilled materials, will be disposed of in a manner subject to the approval of the Indiana Department of Environmental Management. 5. Flushing of spilled material with water will not be permitted unless so authorized by the Indiana Department of Environmental Management. Monitoring and maintenance guidelines for pollution prevention measures: Straw Bale Dam Maintenance Requirements 1. Inspect straw bole dams after each storm event and promptly remove any sediment deposits to insure adequate storage volume for the next rain, taking care not to undermine the entrenched boles. 2. Inspect periodically for deterioration or damage from construction activities and repair immediately. 3. After the contributing drainage area has been stabilized, remove all straw bales and sediment deposits, bring the disturbed area to grade and stabilize it. Silt Fence Maintenance Requirements 1. Inspect the silt fence periodically and after each storm event. 2. If fence fabric tears, starts to decompose or in any way becomes ineffective, replace the affected portion immediately. 3. Remove deposited sediment when it reaches half the height of the fence at it's lowest point or is causing the fabric to bulge. 4. Take care to avoid undermining the fence during cleanout. 5. After the contributing drainage area has been stabilized, remove the fence and sediment deposits, bring the disturbed area to grade and stabilize it. Temporary Sediment Trap Maintenance Requirements 1. Inspect temporary sediment traps after each storm event and immediately repair any erosion and piping holes. 2. Remove sediment when it has accumulated to one -half the design depth. 3. Replace spillway gravel facing when clogged. 4. Inspect vegetation and re -seed if necessary. 5. Check the spillway depth periodically to insure a minimum of 1.5 ft depth from the lowest point of the settled embankment to highest point of the spillway crest and fill any low areas to maintain desired elevation. 6. Promptly replace any displaced rip -rap, being careful that no stones in the spillway are above design grade. 7. After all disturbed areas have been stabilized, remove the structure and sediment, smooth the site to blend with adjoining areas and stabilize it. Sandbag Curb Inlet Barrier Maintenance Requirements 1. Inspect frequently for damage by vehicular traffic and repair if necessary. 2. Inspect after each storm event. 3. Remove sediment, without flushing, when it reaches half the height of the barrier. 4. Deposit removed sediment where it will not enter storm sewer drains. Block and Gravel Curb Inlet Protection Maintenance Requirements 1. After each storm event remove the sediment and replace the gravel, replace the geotextile fabric if used. 2. Periodically remove sediment and tracked -on soil from the street, without flushing, to reduce the sediment load on the curb inlet protection. 3. Inspect periodically for damage and repair. Keep grates free of debris. 4. After the contributing drainage area has been stabilized, remove the gravel, wire mesh, geotextile fabric and sediment deposits and dispose of them properly. Erosion Control Blanket (Surface Applied). Maintenance Requirements 1. During vegetative establishment, inspect after each storm event for any erosion below the blanket. 2. If any area(s) shows erosion, pull back that portion of the blanket covering it, re- seed the area and relay and staple the blanket. 3. After vegetative establishment check the treated area periodically. Temporary Gravel Construction Entrance Maintenance Requirements 1. Inspect entrance pad and sediment disposal area weekly and after storm events or heavy use. 2. Reshape as needed for drainage and runoff control. 3. Topdress with clean stone as needed. 4. Immediately remove mud and sediment tracked or washed onto streets by brushing or sweeping. Flushing should only be used if the water is conveyed into a sediment trap or basin. 5. Repair any broken road pavement immediately. 3'5 Erosion sediment control specifications for individual building lots: Not applicable. See Sheets BP1 -C1.62 -1.63 for Construction details and specifications for erosion sediment control on this site. Description of pollutants and their sources associated with the proposed land use: Silt and sediment from exposed soils, leaves, mulch, vehicular sources such as leaking fuel or oil, brake fluid, brake dust, grease, antifreeze, metals, rubber fragments, road grit, salts and sands, construction trash and debris, fertilizers, household items including but not limited to cleaning agents, chemicals, paint, miscellaneous home improvement materials, toys, clothing and animal waste, elevated storm runoff temperatures, acid rain pesticides and pathogens. Sequence describing stormwater quality measure implementation: 1. Inspect and maintain all erosion control measures as detailed in the Stormwater Pollution Prevention Measures Maintenance Requirements beginning immediately after installation and continuing until vegetation has been sufficiently established and all construction activity is complete. 2. Remove all individual inlet protection and straw bale dams, silt fences, etc. only after seeding and sufficient vegetative growth has been established in each area to a point where sediment /pollutants will not enter the waterway or storm sewer system. 3. It is recommended that any proposed wetland areas and plantings (if any) be constructed /placed after final grading and sufficient vegetative growth has been established to a point where sediment /pollutants will not enter the proposed wetlands. 4. Inspection and maintenance of all common areas and infrastructure improvements is the responsibility of the owner /developer or his designee until improvements are accepted for maintenance by an association or local agencies. 5. Inspection and maintenance is the responsibility of the developer /owner or his designee until project completion and the owner thereby accepts responsibility for the individual lot. Description of proposed post construction stormwater quality measures: Site and facility design for stormwater quality protection on this site employs a multi -level strategy consisting of: 1. Reducing or eliminating post project runoff. 2. Controlling sources of pollutants. 3. And if needed, treating contaminated stormwater runoff before discharging it into the storm sewer system or receiving waters. Typical stormwater quality measures for reducing, eliminating or controlling pollutants (source controls) include: a. Detention/Retention devices that includes a 12 acre lagoon /wetland that will serve as the overall setention facility for the site. b. Reducing Runoff or Direct runoff from impervious areas c. Vegetated strips and bio- filtration swales that will carry the water through and from the parking areas the lagoon. t o a a eas to e oon. P 9 9 d. Permanent erosion control seeding and plantings e. Outlet protection velocity dissipation devices f. Earthen dikes, drainage swains and lined ditches g. Rock slope protection h. Mulching It is the intent of this plan that the implementation of the above described storm water quality measures be executed in accordance with the enclosed plans and details in order to meet the requirements of Rule 5 storm water quality. Location, dimensions, specifications and construction details of stormwater quality measures: See Stormwater Pollution Prevention Plan Sheet BP1 -C1.60 -1.61 for locations of permanent stormwater quality measures and Sheets BP1 -C1.62 -1.63 for construction details and specifications. C5 Description of maintenance guidelines for proposed water quality measures: for this set of plans, the measures need to be inspected weekly and after every rainfall, with repairs taking place immediately if needed. ADDITIONAL STORMWATER POLLUTION PREVENTION MEASURES VEHICLE EQUIPMENT MAINTENANCE Description and Purpose Prevent or reduce the contamination of stormwater resulting from vehicle and equipment maintenance by running o "dry and clean site The best option would be to perform maintenance activities at an offsite facility. If this option is not available then work should be performed in designated areas only, while providing cover for materials stored outside, checking for leaks and spills, and containing and cleaning up spills immediately. Suitable Applications These procedures are suitable on all construction projects where an onsite yard area is necessary for storage and maintenance of heavy equipment and vehicles. Limitations Onsite vehicle and equipment maintenance should only be used where it is impractical to send vehicles and equipment offsite for maintenance and repair. Sending vehicles /equipment offsite should be done in conjunction with a Stabilized Construction Entrance /Exit. Outdoor vehicle or equipment maintenance is a potentially significant source of stormwoter pollution. Activities that can contaminate stormwater include engine repair and service, changing or replacement of fluids, and outdoor equipment storage and parking (engine fluid leaks). Implementation If maintenance must occur onsite, use designated areas, located away from drainage courses. Dedicated maintenance areas should be protected from stormwater runon and runoff, and should be located at least 50 ft from downstream drainage facilities and watercourses. Drip pans or absorbent pods should be used during vehicle and equipment maintenance work that involves fluids, unless the maintenance work is performed over an impermeable surface in a dedicated maintenance area. Place a stockpile of spill cleanup materials where it will be readily accessible. r are required have spill kits and/or fueling trucks and fueling areas a e e u ed to a e d or use other spill u s q P 9 9 P protection devices. Use adsorbent materials on small spills. Remove the absorbent materials promptly and dispose of properly. Inspect onsite vehicles and equipment daily at startup for leaks, and repair immediately. Keep vehicles and equipment clean; do not allow excessive build -up of oil and grease. Segregate and recycle wastes, such as greases, used oil or oil filters, antifreeze, cleaning solutions, automotive batteries, hydraulic and transmission fluids. Provide secondary containment and covers for these materials if stored onsite. Train employees and subcontractors in proper maintenance and spill cleanup procedures. Drip pans or plastic sheeting should be placed under all vehicles and equipment placed on docks, barges, or other structures over water bodies when the vehicle or equipment is planned to be idle for more than 1 hour. Properly dispose of used oils, fluids, lubricants, and spill cleanup materials. Do not place used oil in a dumpster or pour into a storm drain or watercourse. Properly dispose of or recycle used batteries. Do not bury used tires. Repair leaks of fluids and oil immediately. Listed below is further information if you must perform vehicle or equipment maintenance onsite. Inspection and Maintenance Inspect and verify that BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly to verify continued BMP implementation. Keep ample supplies of spill cleanup materials onsite. Maintain waste fluid containers in leak proof condition. Vehicles and equipment should be inspected on each day of use. Leaks should be repaired immediately or the problem vehicle(s) or equipment should be removed from the project site. Inspect equipment for damaged hoses and leaky gaskets routinely. Repair or replace as needed. HICI AN": FUL PhlF'NT F.F ING Description and Purpose Vehicle equipment fueling procedures and practices are designed to prevent fuel spills and leaks, and reduce or eliminate contamination of stormwater. This can be accomplished by using offsite facilities, fueling in designated areas only, enclosing or covering stored fuel, implementing spill controls, and training employees and subcontractors in proper fueling procedures. Limitations Onsite vehicle and equipment fueling should only be used where it is impractical to send vehicles and equipment offsite for fueling. Sending vehicles and equipment offsite should be done in conjunction with a Stabilized Construction Entrance/ Exit. Implementation Use offsite fueling stations as much as possible. These businesses are better equipped to handle fuel and spills properly. Performing this work offsite can also be economical by eliminating the need for a separate fueling area at a site. Discourage "topping -off" of fuel tanks. Absorbent spill cleanup materials and spill kits should be available in fueling areas and on fueling trucks, and should be disposed of properly after use. Drip pans or absorbent pods should be used during vehicle and equipment fueling, unless the fueling is performed over an impermeable surface in a dedicated fueling area. Use absorbent materials on small spills. Do not hose down or bury the spill. Remove the adsorbent materials promptly and dispose of properly. Avoid mobile fueling of mobile construction equipment around the site; rather, transport the equipment to designated fueling areas. Train employees and subcontractors in proper fueling and cleanup procedures. Dedicated fueling areas should be protected from stormwater runon and runoff, and should be located at least 50 ft away from downstream drainage facilities and watercourses. Fueling must be performed on level -grade areas. Protect fueling areas with berms and dikes to prevent runon, runoff, and to contain spills. Nozzles used in vehicle and equipment fueling should be equipped with an automatic shutoff to control drips. Fueling operations should not be left unattended. Federal, state, and local requirements should be observed for any stationary above ground storage tanks. Inspection and Maintenance Vehicles and equipment should be inspected each day of use for leaks. Leaks should be repaired immediately or problem vehicles or equipment should be removed from the project site. Keep ample supplies of spill cleanup materials onsite. Immediately clean up spills and properly dispose of contaminated soil and cleanup materials. Cee Ii t'AN'f 1 NT Description and Purpose Solid waste management procedures and practices are designed to prevent or reduce the discharge of pollutants to stormwater from solid or construction w s providing on o to by d 9 P yP 9 designated waste collection areas and containers, arranging for regular disposal, and training employees and subcontractors. Suitable Applications This BMP is suitable for construction sites where the following wastes are generated or stored: Solid waste generated from trees and shrubs removed during land clearing, demolition of existing structures (rubble), and building construction Packaging materials including wood, paper, and plastic Scrap or surplus building materials including scrap metals, rubber, plastic, glass pieces and masonry products Domestic wastes including food containers such as beverage cans, coffee cups, paper bags, plastic wrappers, and cigarettes Construction wastes including brick, mortar, timber, steel and metal scraps, pipe and electrical cuttings, nonhazardous equipment parts, styrofoam and other materials send transport and package construction materials Implementation The following steps will help keep a clean site and reduce stormwater pollution: Select designated waste collection areas onsite. Inform trash- hauling contractors that you will accept only watertight dumpsters for onsite use. Inspect dumpsters for leaks and repair any dumpster that is not watertight. Provide an adequate number of containers with lids or covers that can be placed over the container to keep rain out or to prevent loss of wastes when it is windy. Plan for additional containers and more frequent pickup during the demolition phase of construction. Collect site trash daily, especially during rainy and windy conditions. Remove this solid waste promptly since erosion and sediment control devices tend to collect litter. Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids, pesticides, additives, curing compounds) ore not disposed of in dumpsters designated for construction debris. Do not hose out dumpsters on the construction site. Leave dumpster cleaning to the trash hauling contractor. Arrange for regular waste collection before containers overflow. Clean up immediately if a container does spill. Make sure that construction waste is collected, removed, and disposed of only at authorized disposal areas. Collection. Storage, and Disposal Littering on the project site should be prohibited. To prevent clogging of the storm drainage system, litter and debris removal from drainage grates, trash racks, and ditch lines should be a priority. Trash receptacles should be provided in the contractor's yard, field trailer areas, and at locations where workers congregate for lunch and break periods. Litter from work areas within the construction limits of the project site should be collected and laced in watertight dumpsters at least weekly, regardless of whether the litter was generated by he contractor, the public, or others. Collected litter and debris should not be planed in or next to drain inlets, stormwater drainage systems, or watercourses. Dumpsters of sufficient size and number should be provided to contain the solid waste generated by the project. Full dumpsters should be removed from the project site and the contents should be disposed of by the trash hauling contractor. Construction debris and waste should be removed from the site biweekly or more frequently as needed. Construction material visible to the public should be stored or stacked in an orderly manner. Stormwater runon should be prevented from contacting stored solid waste through the use of berms, dikes, or other temporary diversion structures or through the use of measures to elevate waste from site surfaces. Solid waste storage areas should be located at least 50 ft from drainage facilities and watercourses and should not be located in areas prone to flooding or ponding. Inspectio° arc Mcintencrce Inspect and verify that activity -based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly to verify continued BMP implementation. Inspect BMPs subject to non- stormwater discharge doily while non stormwater discharges occur Inspect construction waste area regularly. Arrange for regular waste collection. COV,RFTF WASHOUT The following steps will help reduce stormwater pollution from concrete wastes: Discuss the concrete management techniques described in this BMP (such as handling of concrete waste and washout) with the ready -mix concrete supplier before any deliveries are made. Incorporate requirements for concrete waste management into material supplier and subcontractor agreements. Store dry and wet materials under cover, away from drainage areas. Avoid mixing excess amounts of fresh concrete. Perform washout of concrete trucks offsite or in designated areas only. Do not wash out concrete trucks into storm drains, open ditches, streets, or streams. Do not allow excess concrete to be dumped onsite, except in designated areas. For onsite washout: Locate washout area at least 50 feet from storm drains, open ditches, or water bodies. Do not allow runoff from this area by constructing a temporary pit or bermed area large enough for liquid and solid waste. Wash out wastes into the temporary pit where the concrete can set, be broken up, and then disposed properly. Avoid creating runoff by draining water to a bermed or level area when washing concrete to remove fine particles and expose the aggregate. Do not wash sweepings from exposed aggregate concrete into the street or storm drain. Collect and return sweepings to aggregate base stockpile or dispose in the trash. DEWATER 'NJC AND UF,1PIl1 OPERATIC!NJS Description and Purpose Dewatering operations are practices that manage the discharge of pollutants when non stormwater and accumulated precipitation must be removed from a work location so that construction work may be accomplished. Suitable Applications These practices are implemented for discharges of nonstormwater from construction sites. Non stormwaters include, but are not limited to, groundwater, water from cofferdams, water diversions, and waters used during construction activities that must be removed from a work area. Practices identified in this section are also appropriate for implementation when managing the removal of accumulated precipitation(stormwater) from depressed areas at a construction site. Limitations Site conditions will dictate design and use of dewatering operations. The controls discussed in this best management practice (BMP) address sediment only. The controls detailed in settling BMP only allow for minimal sett g t im e for o se diment i the of the when site r rctteuseo Use only whe� s to est particles. U e o y other control methods. Dewatering operations will require, and must comply with, applicable local permits. Implementation Dewatering discharges must not cause erosion at the discharge point. A variety of methods can be used to treat water during dewatering operations. Several devices are presented below and provide options to achieve sediment removal. The size of particles present in the sediment and Permit or receiving water limitations on sediment are key considerations for selecting sediment treatment option(s); in some cases, the use of multiple devices may be appropriate. Sediment Basin A sediment basin is a temporary basin with a controlled release structure that is formed by excavation or construction of an embankment to detain sediment -laden runoff and allow sediment to settle out before discharging. Sediment basins are generally larger than Sediment Traps. Effective for the removal of gravel, sand, silt, some metals that settle out with the sediment, and trash. Excavation and construction of related facilities is required. Temporary sediment basins must be fenced if safety is a concern. Outlet protection is required to prevent erosion at the outfall location. Maintenance is required for safety fencing, vegetation, embankment, inlet and outfall structures, as well as other features. Removal of sediment is required when the storage volume is educed by one -half. Sediment Trap A sediment trap is a temporary basin formed by excavation and /or construction of an earthen embankment across a waterway or low drainage area to detain sediment -laden runoff and allow sediment to settle out before discharging. Sediment traps are generally smaller than Sediment Basins. HL Jf_i.' t /p L t �,u i Effective for the removal of (sand and large and medium sized particles 9 P gravel) and some metals that settle out with the sediment. Excavation and construction of related facilities is required. Trap inlets should be located to maximize the travel distance to the trap outlet. Use rock or vegetation to protect the trap outlets against erosion. Maintenance is required for vegetation, embankment, inlet and outfall structures, as well as other features. Removal of sediment is required when the storage volume is reduced by one third. SOILS MAP Soils Legend Descriptions: NOT TO SCALE Br Brookston silty clay loam, Soil Description and Characteristics: The main soil features that adversely affect engineering uses of this soil are a seasonal high water table, high potential frost action, moderate shrink -swell potential and moderate permeability. This soil has severe limitations for building sites. The site needs to be artificially drained and protected from flooding. Dwellings with basements should not be constructed on this soil. This soil has severe limitations for local roads and streets because of seasonal high water table and high potential frost action. The base material for roads and streets should be replaced or strengthened with suitable material.

MmB2 Miami Silt Loam, Soil Description and Characteristics: The main soil features that adversely affect engineering uses of this soil are moderate potential frost action, moderate shrink -swell potential, moderate permeability and low strength. In addition, erosion is a hazard during construction. This soil is suitable for building sites, but slope, clayey texture, shrinking and swelling, and low strength are moderate limitations that need to be overcome. This soil has severe limitations for local roads and streets because of low strength. The base material for roads and streets should be replaced or strengthened with suitable material. Wh Whitaker Loam, Soil Description and Characteristics: The main soil features that adversely affect engineering uses of this soil are seasonal high water table, high potential frost action, and moderate permeability. In addition, erosion is a hazard during construction. This soil has severe limitations for building sites. The sites need to be artificially drained to prevent wetness from becoming a problem. This soil has severe limitations for local roads and streets because of high water table and frost action. Installation of ditches helps to lower the water table and prevent frost action. The base material for roads and streets should be replaced or strengthened with suitable material.
