Introduction This report represents the Stormwater Management Plan for construction of the College and Trilby Multi-Family Community. It was prepared to meet the regulatory requirements of the City of Fort Collins Stormwater Criteria Manual as well as the Colorado Department of Health, Water Quality Control Division in compliance with the provisions of the Colorado Water Quality Control Act, and the Federal Water Pollution Control Act. This plan serves as a consolidated document for information on water quality protection for the subject site and areas immediately adjacent. It should also be noted that this plan is a living document that will need to be updated and maintained throughout the construction process. The intent of this plan is to provide the contractor a tool to consolidate records, logs, permits, applications, etc. as well as guidance on water quality protection. The plan incorporates elements that can be found in the contract plans and specifications as well as in the City of Fort Collins Stormwater Criteria Manual. 1.2. Current Conditions College and Trilby is located in the Southwest Quarter of Section 11, Township 6 North, Range 69 West of the 61" P.M. in the City of Fort Collins, Larimer County, Colorado. More specifically, the site is a 39.1803-acre property that is currently undeveloped. The site borders College Ave to the east, to the south, the site borders Trilby Road, South Gate Church, and a right in right out with access to Ziggy's Coffee. To the west, the site borders a detention pond that controls runoff for the first free will Baptist Church, the Skyview South Fist Filing Subdivision, and a social services organization owned by Foothils Gateway Inc. to the north, the site borders Hazel Self Storage, two current vacant parcels of land, and a portion of Skyview Drive. For additional information, refer to the site vicinity map within Appendix A of this report. The site generally drains west to east at a 10%to 4% slope. The majority of the site is undeveloped and has several existing farm buildings scattered throughout the site. There are two existing culvert crossings under College Avenue along the eastern boundary of the subject property. The two existing culverts drain from the east side under College Avenue. the two crossings identified as south and north. The north crossing is 48" pipe that gets downsized to a 30" pipe downstream.The south crossing is a 24" pipe. College Avenue creates two inadvertent detention ponds on the subject property due to attenuation/ponding of storm runoff. The inverts of the culverts are such that standing water remains after rainfall events, creating wetland areas on the site. The site is located in the Fossil Creek Basin, specifically within the Stone Creek sub-Basin. The Stone Creek master drainage plans identify these two independent COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN detention areas and specify that these be preserved with the future development of the site. The North Loudon Ditch and Reservoir Company has a 30" gravity irrigation line that goes through the site adjacent and along the northern boundary of the site. The site currently has a small shed and gravel access road; the majority of the site is primarily vacant with native grass.The Natural Resources Conservation Service (NRCS) soil survey shows that the majority of the soils on the site are composed of type B soils, which have a mild infiltration and runoff rate. The remaining site is made up of Type C and D soils. Which are characterized by a lower infiltration rate and corresponding higher runoff rates. For additional information, refer to the NRCS soil map within Appendix A of this report. 1.3. Nature and Purpose of Construction College & Trilby is a residential multi-family development that will consist of a recreation center, alleys, and local and collector roadways. The College & Trilby site will hold detention and water quality improvements for the College and Trilby in continuity with the Stone Creek Master Plan. 1.4.Wetlands and Receiving Waters The large pond located on site is the wetland mitigation area. The receiving waters are in the Fossil Creek Basin, specifically within the Stone Creek sub-Basin. 1.5. Rainfall Erodibility & Erosion Sediment Control Methods Attached at the end of the this report are a series of drawings that describe the proposed site conditions, as well as the locations of the erosion control Best Management Practices (BMPs). The Erosion Control Plan depicts the anticipated drainage patterns after major grading activities and the anticipated locations for BMPs such as silt fence, inlet protection, and staging areas. It has been assumed that the majority of the surrounding areas will remain in their present state during the construction of this project. The Contractor will be responsible for implementing and maintaining the erosion and sediment control measures described in the document and the accompanying design drawings. The Contractor may designate these tasks to certain subcontractors as he sees fit, but the ultimate responsibility for implementing these controls and their proper function at each phase of the project remains with the Contractor. The order of major activities will be as follows: 1. Install vehicle tracking control and other perimeter soil erosion control measures. 2. Clear and rough grade for improvements. 3. Excavate and install improvements including underground piping, manholes, and drainage structures. COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN 4. Fine grading. 5. Install trails. 6.

Netting/Blankets/Mats 1.6. Non-Stormwater Discharge Non-stormwater discharges will be eliminated or reduced to the fullest extent feasible. This plan does not cover construction dewatering. Pumping or draining groundwater that has infiltrated into an excavation requires a general permit for construction dewatering, regardless of the size of the project. Stormwater that mixes COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN with groundwater in an excavation is also subject to the controls in the general permit for Construction Dewatering. No materials shall be discharged in quantities that will have an adverse effect on the receiving waters. The measures listed below will be implemented to achieve these objectives. • Proper and lawful disposal of all waste materials. • Control any spills and leaks that may occur and clean up (mitigate). • Use of designated areas for equipment repair and cleaning. • Careful application of irrigation water. All potential pollutants used during construction other than sediment,will be handled and disposed of in a manner that does not contaminate storm water. All materials used during construction, which have the potential to impact storm water quality will be stored, managed, used and disposed of in a manner that minimizes the potential for releases to the environment, especially storm water. 2.0 STORMWATER MANAGEMENT CONTROLS 2.1. Controls Overview During construction, several controls and measures shall be implemented under the direction of the General Contractor to prevent offsite discharge of contaminated storm water. Controls for this project include erosion, sedimentation, stabilization, and other BMPs. Specifications and engineering drawings for the selected BMPs can be found on the drawing included in the back pocket of this. The contractor shall comply with the attached plans and guidelines as a minimum. Field conditions and unforeseen circumstances will dictate modifications to or additions to this Stormwater Management Plan. Where storm water pollution potential exists, appropriate preventative measures (BMPs) must be utilized and documented, whether such measures are identified in this report or not. 2.2. Erosion and Sediment Controls The objective of erosion control is to limit the amount of erosion occurring on disturbed areas until the site is stabilized. The objective of sediment control is to capture the soil that has been eroded before it leaves the construction site. Despite the use of both erosion and sediment control measures, it is recognized that some sediment could remain in runoff leaving the construction site. This should be minimized to the maximum extent practicable. COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN The BMPs scheduled for use during the construction of this site can be divided into Structural and Non-Structural Practices. Section 2.2.1 of this report discusses the proposed structural BMPs to be utilized. Section 2.2.2 discusses the non-structural practices. 2.2.1. Structural Practices (See drawings for locations) Structural BMPs are structural site management practices that will minimize erosion and sediment transport. Such practices may include silt fences, drainage swales, inlet protections, outlet protection, etc. The goal of structural BMPs on this project is to protect areas downstream of the site from turbid water, sediment, oils and other contaminants, which may mobilize during storm water flows. The structural BMPs that may be utilized on the subject site are depicted in the Drainage and Erosion Control Plan and are described in more detail as follows: Silt Fence: • A temporary vertical barrier of filter fabric attached to and supported by posts and entrenched into the ground. • Utilized to intercept sediment from disturbed areas during construction operations. • Used to filter shallow sheet flow. • Typically used along the toe of fills, in transition areas between cut and fills, and adjacent to streams. • Generally installed prior to or immediately following land-disturbance activity. • Shall be inspected periodically and after each rain or snowfall event and repaired when necessary. Sediment shall be removed from behind the fence when it accumulates to one-half the exposed fabric height. Sediments removed must be properly disposed. • Utilized as a temporary feature. Sediment Control Log: • A temporary vertical barrier of rolled natural materials such as straw or other fibrous material (also known as wattles). • Utilized to intercept sediment from disturbed areas during construction operations. • Used to filter shallow sheet flow. • Typically used as perimeter control inlet protection, on disturbed slopes,along the toe of fills, in transition areas between cut and fills, and adjacent to streams. • Generally installed prior to or immediately following land-disturbance activity. • Shall be inspected periodically and after each rain or snowfall event and repaired when necessary. Sediment shall be removed from behind the fence when it accumulates to one-half the exposed log height. Sediments removed must be properly disposed. COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN • Utilized as a temporary feature. Inlet Protection: • A barrier across or around a storm drain drop inlet, a curb inlet, or a culvert inlet. • Utilized to intercept and filter sediment-laden runoff and prevent it from entering storm drainage systems. • Not to be utilized in place of a sediment-trapping device. Used as a secondary control device. • Do not use where ponded water might flow onto the roadway. • Blocking of the inlet should not be watertight. • Generally installed prior to land-disturbance activity on existing inlets and immediately after the construction of new inlets. • Shall be inspected periodically and after each rain or snowfall event and repaired when necessary. Accumulated sediment shall be removed and properly disposed. • Utilized as a temporary feature. Outlet Protection: • A structurally lined apron (generally with riprap, grouted rip rap, or concrete) placed at the outlet of pipes or paved channel sections. • Used as an energy dissipation device to prevent scour and erosion at the outlet by reducing the velocity and energy of concentrated flow. • Shall be installed immediately following the construction of the upstream conveyance element. • Inspection shall be performed after high flows for scour and dislodged stones. Repairs shall be made immediately. • Utilized as a permanent feature. Grading Techniques: • Soil surface roughening,terracing and rounding at tops of cuts,transitions and roadway ditches to facilitate plant establishment and minimize erosion. • Utilized to temporarily stabilize disturbed areas and protect from wind and water erosion immediately after grading activities have ceased. • Used as a temporary practice during construction. • Inspection and maintenance must be provided periodically and after each rain or snowfall event that causes runoff to ensure roughened state is maintained. • Rills developed should be filled and the area re-graded immediately. Erosion control measures are the responsibility of the General Contractor to inspect and maintain. Any existing erosion control devices that are removed in order to complete the construction of the utilities shall be replaced immediately following the COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN construction that required its removal unless directed otherwise by the construction plans. 2.2.2. Non-Structural Practices (See drawings for locations) Non-Structural BMPs are both interim and permanent stabilization practices. Such practices may include temporary seeding, permanent seeding, mulching, geotextiles, sod stabilization, vegetative buffer strips, tree protection, preservation of mature vegetation, etc. The non-structural BMPs that may be utilized on the subject site are described in more detail as follows: Temporary and Permanent Seeding: • Soil preparation, seeding, mulch tackifier and/or mulching shall be required for all disturbed areas that are not surfaced. • Exposed soils, which are not part of the active grading and/or construction activity, shall be stabilized. • Seeded areas shall be inspected frequently. If the seeded areas fail to establish, provide adequate ground coverage. If seeded areas are disturbed, the area should be re-seeded. • Permanent landscaping and vegetative cover is depicted on the Landscaping plans. Mulching: • Application of plant residues to the soil surface. Typical mulching material includes certified weed free hay or straw, certified under the Colorado Department of Agriculture Weed Free Forage Certification Program as regulated by the Weed Free Forage Act, Title 35, Article 27.5, CRS and wood cellulose fiber. • Utilized in combination with mulch tackifier for temporary erosion control (i.e., incomplete slopes, detour slopes, stockpiles). • Utilized in combination with mulch tackifier for temporary erosion control on slopes when seeding is not allowed due to seasonal constraints. • Used to cover permanent or temporary seed areas. Hydromulch shall not be done in the presence of free surface water. • Inspect frequently and reapply mulching in areas where the mulching has been loosened or removed. Mulch tackifier must be applied with additional applications of mulching. Mulch Tackifier: • An organic soluble powder adhesive used as a water slurry to adhere native hay, straw, hydromulch, or seed to a surface and together. • Used to cover disturbances as temporary cover for wind erosion. COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN • Mulch movement indicates poor application and procedure mixture. • Proper application will bond mulch material together and to soil. • Inspect by touching mulch surface to determine if adhesion has occurred. Maintain Existing Vegetation: • Existing vegetation should be preserved where possible to prevent the migration of sediment. • Should be inspected regularly. • Establish and maintain buffers. • Areas beginning to show signs of erosion or soil transport may require additional emergency BMPs. 2.2.3. Other Controls (See drawings for location) Vehicle Tracking Control/ Construction Entrance: • A temporary stabilized layer of aggregate underlined with geotextile or gravel located where traffic enters or exits the construction site. • The structure shall be constructed prior to any construction activity and maintained daily. • Stone shall be added and repairs performed as conditions require. • When mud is present and not easily removed by a tracking pad, tire washing should be implemented as needed. Tire washing operations should occur near the construction exit on a stabilized stone pad. Implementation of a tire washing area should include provisions for collecting wash water and directing it to an onsite pond. Tracking of Sediment onto Roads and Streets: • Public and private roadways shall be kept clear of accumulated sediment. Bulk clearing of accumulated sediment shall not include flushing the area with water. Sediment will be shoveled and or swept from the street and disposed of in a manner that prevents contamination of storm water or surface water runoff. Concrete Washout Area for Residual Concrete Disposal: • Concrete waste management involves designating and properly managing a specific area of the construction site as a concrete washout area. • The use of the washout site should be temporary (less than 1 year). • The washout site should be not be located in an area where shallow groundwater may be present, such as near natural drainages, springs, or wetlands. • Do not locate an unlined washout area within 400 feet of any natural drainage pathway or waterbody or within 1,000 feet of any wells or drinking water sources. COLLEGE & TRILBY STORMWATER MANAGEMENT PLAN • Remove concrete waste in the washout area, as needed to maintain BMP function • Upon termination of use of the washout site, accumulated solid waste, including concrete waste and any contaminated soils, must be removed from the site to prevent on-site disposal of solid waste. If the wash water is allowed to evaporate and the concrete hardens, it may be recycled. Stabilized Staging Area: • See Detail SM-6 of Urban Storm Drainage Criteria Manual Volume 3 2.3. SWMP Administrator Implementation and management of the environmental aspects of this project under this SWMP Plan are the responsibilities of the General Contractor. The General Contractor shall ensure the all contractors providing services on the project have access to a copy of the SWMP Plan and appropriate training regarding storm water pollution prevention. The General Contractor, Building Contractor, Utility Installations Contractor, Grading Contractor and all other contractors and subcontractors shall be familiar with the SWMP Plan and their responsibilities on the plan. 2.4. Materials Management 2.4.1. Potential Pollution Sources It is anticipated that this construction project will not utilize any abnormal or atypical hazardous materials. The construction site will operate much like other typical construction projects. The following materials or substances are expected to be present onsite during construction: Concrete/Additives/Wastes Cleaning solvents Detergents Petroleum based products Paints/Solvents Pesticides Acids Fertilizers Solid and construction wastes Sanitary wastes Soil stabilization additives COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN Activities on the site that may have an impact on stormwater include the following: • Equipment and/or vehicle washing • Fertilizers, chemicals, or other material storage • Vehicle maintenance or fueling • Waste incineration, treatment, storage or disposal • Off-site vehicle tracking • Loading/unloading areas • Concrete truck washout As construction progresses,specific areas shall be designated for vehicle maintenance and refueling, material and waste storage, construction equipment staging, and bathroom facilities. Management measures and procedures for these facilities are discussed later in the plan. 2.4.2. Pollution Prevention Measures Pollution prevention measures shall be utilized to prevent construction materials with the potential of polluting stormwater, such as those listed above, from coming in contact with runoff. Measures include good housekeeping and proper disposal of construction and demolition debris, equipment fuel, lubricants, paints and solvents, asphalt, concrete, topsoil and other materials, as well as controls which prevent sediments from being tracked off-site by construction vehicles, and proper control of any non-stormwater flows on-site. As previously stated, Best Management Practices (BMPs) are schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce pollution of public waters. BMPs also control site runoff, spillage or leaks,sludge or waste disposal, or drainage from raw material storage. With regard to construction,these may include structural controls and nonstructural practices that are designed to prevent pollutants from entering water or direct the flow of water away from potential sources of pollution. For construction sites,there are three main types of BMPs,those that prevent erosion and sediment transport, others that prevent pollutants from construction materials from mixing with stormwater, and those that trap pollutants before they can be discharged. BMPs for most common construction materials and wastes with the greatest potential for adversely affecting stormwater quality are as follows: BMPs for Disturbed and Stored Soils: • Seeding and mulching should be completed for the site COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN • Soil preparation, seeding, mulch tackifier and/or mulching shall be required for all disturbed areas that are not surfaced. • Exposed soils, which are not part of the active grading and/or construction activity, shall be stabilized. • Seeded areas shall be inspected frequently. If the seeded areas fail to establish, provide adequate ground coverage. If seeded areas are disturbed, the area should be re-seeded. • Permanent landscaping and vegetative cover is depicted on the Landscaping plans. • During construction activities, silt fence, straw wattle and inlet protection will be used as described in 2.2.1 to prevent disturbed and stored soils from leaving the site before the seeding an permanent landscape can reach final stabilization. BMPs for Vehicle Tracking of Sediment: • Use vehicle tracking pads at the entrances of construction • Public and private roadways shall be kept clear of accumulated sediment. Bulk clearing of accumulated sediment shall not include flushing the area with water. Sediment will be shoveled and or swept from the street and disposed of in a manner that prevents contamination of storm water or surface water runoff. • A temporary stabilized layer of aggregate underlined with geotextile or gravel located where traffic enters or exits the construction site. • The structure shall be constructed prior to any construction activity and maintained daily. • Stone shall be added and repairs performed as conditions require. • When mud is present and not easily removed by a tracking pad, tire washing should be implemented as needed. Tire washing operations should occur near the construction exit on a stabilized stone pad. Implementation of a tire washing area should include provisions for collecting wash water and directing it to an onsite pond BMPs for Management of Contaminated Soils: • Have equipment to contain and clean up spills of hazardous materials in the vicinity of where these materials are to be stored or used. • Contain and clean up spills immediately after they occur.Contact State or Local solid waste regulatory agency concerning information and procedures necessary to treat or dispose of contaminated soils. • Keep materials in a dry covered area and elevated from the ground. BMPs for Loading and Unloading Operations: • Select a loading and unloading area for the site COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN BMPs for Outdoor Storage Activities: • Select an outdoor storage area for the site • When possible store equipment and material in covered areas BMPs for Equipment Maintenance and Fueling: • Fueling operations shall occur in a designated area. • Have equipment to contain and clean up petroleum spills in fuel storage areas or on board maintenance and fueling vehicles. • Where possible, store petroleum products and fuel vehicles in covered areas and construct dikes to contain spills. • Contain and clean up spills immediately. • Use preventive maintenance for onsite equipment such as checking for and fixing gas and oil leaks in construction vehicles on a regular basis. • Follow proper procedure for the handling and application of asphaltic substances. • Oversee all filling operations. • Fueling equipment and area shall be fenced and valving locked to prevent vandalism. BMPs for Significant Particulate Generating: • Use silt fence and inlet protection to protect the areas downstream of the site • Maintain and clean out any sediment that builds up around the inlet protection and silt fence BMPs for On-Site Waste Management: • Select a designated waste collection area onsite. • Provide an adequate number of containers with lids or covers that can be placed over the containers prior to rainfall. • When possible, locate containers in a covered area. • Arrange for waste collection before containers overflow. • If a container does spill, provide cleanup immediately. • Plan for additional containers and more frequent pickups during the demolition phase of construction. • Make sure that construction waste is collected, removed, and disposed of only at authorized disposal areas. • Check with local solid waste management agency for specific guidance. • Trash, debris and spoils shall be properly contained at the END of EACH day. BMPs for residual Concrete disposal: COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN • Emptying or wash out of excess concrete may be allowed on site. Excess concrete and wash water should be disposed of in a manner that prevents contact between these materials and stormwater discharges from the site. • Residual concrete shall be discharged in specifically designated dike areas, which have been prepared to prevent contact between the concrete and/or washout and stormwater discharged from the site and/or ground water. • The hardened residue from the dike areas shall be disposed of in the same manner as other non-hazardous construction waste materials or may be broke up and utilized as deemed appropriate by the contractor. • The use of the washout area shall be temporary (less than one year). • Washing of trucks and masonry equipment is to be performed only at a designated concrete washout. No burying of wastes. BMPs for Sanitary/Septic Wastes: • Sanitary or septic wastes that are generated onsite should be treated or disposed of in accordance with State or local requirements. • If self-contained, temporary facilities are utilized, the domestic waste haulers should be contracted to regularly remove the sanitary and septic wastes and to maintain the facilities in good working order. • Any facilities to be connected to a sanitary sewer system should be properly hooked to the sanitary sewer system to prevent illicit discharges. • Untreated, raw sewage should never be discharged or buried onsite. • Contact local government and State regulatory agencies to ensure the compliance with State or local requirements. • If sewage is being discharged to the sanitary sewer, the local treatment works authority should be contacted. BMPs for pesticides: • Store pesticides in a dry covered area and elevate above the ground. • Provide curbs or dikes to contain possible spills. • Have measures on site to contain and clean up spills. • Strictly follow recommended application rates and recommended application methods. • Only a Certified Applicator shall use pesticides. BMPs for Fertilizers/Detergents: • Limit the application of fertilizers to the minimum area and minimum recommended amounts. • Reduce exposure of nutrients to storm water runoff by working the fertilizer deep into the soil. • Apply fertilizer more frequently, but at lower application rates. COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN • Hydro seeding, where lime and fertilizers are applied to the ground surface in one application should be limited, where possible. • Limit the use of detergents onsite: wash water containing detergents should not be discharged to the storm system. • Implement good erosion and sediment control to help reduce the amount of fertilizers that can leave the site as well as sediments. • Fertilizers and detergents shall be stored in dry and covered area and elevated above the ground. • Berming shall be provided around the storage area to avoid contact with stormwater runoff. BMPs for Hazardous Wastes Disposal: • Check with local waste management authorities to determine what the requirements are for disposing of hazardous materials. • Use the entire product before disposing of the container. • Do not remove the original product label from the container. It contains important information. • Do not mix products together unless specifically recommended by the manufacturer. • The correct disposal of these products varies with the product utilized. Follow the manufacturers recommended method, which is often found on the label. 2.5. Spill Management Construction site supervisors should create and adopt a spill control plan that includes measures and procedures to stop the source of the spill, contain the spill, clean up, and disposal of contaminated materials. Key personnel shall be identified and trained to be responsible for spill prevention and control. The following measures would be appropriate for a spill prevention and response plan: • Store and handle materials to prevent spills. o Tightly seal containers. o Make sure all containers are clearly labeled. o Stack containers neatly and securely o Where possible, store containers on pallets in a covered area. • Reduce stormwater contact if there is a spill. o Have cleanup procedures clearly posted. o Have cleanup materials readily available. o Contain any liquid. o Stop the source of the spill. o Cover spill with absorbent material. COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN • Dispose of contaminated materials according to manufacturer's instructions or according to State or local requirements. • Identify personnel responsible for responding to a spill of toxic or hazardous materials. o Provide personnel spill response training. o Post names of spill response personnel. • Keep the spill area well ventilated. Additionally, records of spills, leaks, or overflows that result in the discharge of pollutants must be documented and maintained. Information such as the time and date, weather conditions, response procedure taken, response personnel involved, reasons for the spill, etc., shall be recorded for all occurrences in the SWMP Plan and on the map. Spill Categories are as follows: Minor Spills • Any event that involves 5 gallons or more and or involves the following: • Less than the reportable quantity • Stays within the permitted area • Does not threaten any stormwater conveyances Significant Spills • Reportable Quantity (SARA title III List of Lists, available from EPA for reportable quantity) • Any amount leaving the permitted area • And/or threatens any water conveyances. Hazardous Spills • Any substance requiring a MSDS response. • Procedure shall include but limited to: o Secure the area o Provide first aid o Notify emergency response personnel Some spills may need to be reported to the Division of Water Quality and the City of Fort Collins immediately. Specifically significant spills that are, a release of any chemical, oil, petroleum product, sewage, etc., which may enter waters of the State of Colorado (which include surface water, ground water and dry gullies or storm sewers leading to surface water), any spill that exceeds the reportable quantity, and any amount that leaves the permitted area must be reported. The Division's toll-free 24-hour environmental emergency spill reporting line is 1-877-518-5608. Written documentation to both the CDPHE (Division) and the City of Fort Collins of significant spills should be provided within 5 days. COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN 3.0 Dry Land Vegetation 3.1. Soil and Surface Conditions The Natural Resources Conservation Service (NRCS) soil survey shows that the majority are type C soils, which are characterized by a lower infiltration rate and corresponding higher runoff rates. The remaining soil on site are made up of Type B soils, which are characterized by a moderate infiltration rate and lower runoff rates. For additional information, refer to the NRCS soil map within Appendix A of this report. 3.2. Seed Mixes The seed mixtures called out in the Landscape Plan will be used for this site. Mixture ratios and appropriate application rates per specified in the Landscape plan shall also be used for this site. If the approved mix is not used than a request to the City must be submitted of the preferred seed mix with the application rates. 3.3. Mulches Typical mulching material includes certified weed free hay or straw, certified under the Colorado Department of Agriculture Weed Free Forage Certification Program as regulated by the Weed Free Forage Act, Title 35, Article 27.5, CRS and wood cellulose fiber. Mulch should be utilized in combination with mulch tackifier for temporary erosion control (i.e., incomplete slopes, detour slopes, stockpiles) when seeding is not allowed due to seasonal constraints. Mulch is also used to cover permanent or temporary seed areas. The mulch should be inspected frequently and reapplied in areas where the mulch has been loosened or removed. Mulch tackifier must be applied with additional applications of mulching. 4.0 Detailed Sequence of Construction Activities Sequence of Land Disturbing Activity Chart Utilities Flat work Vertical Mobilization Demolition Grading Installation Installation Installation Landscape Demobilization Best Management Practices (BMPs) Structural"Installation" Silt Fence Barriers* -_---� Vehicle Tracking Pad* -M- Any prior inlets that could use Einietilter Bags* protecting Any prior inlets that could use ERock Bags* A protecting COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN Rip Rap Collecting Asphalt/ Concrete Saw Cutting Waste *All BMPs to be Removed once Construction is Complete.

Inspection and Maintenance Overview A site inspection of all erosion control facilities shall be conducted at least once every two weeks and immediately following any significant precipitation or snowmelt event that could cause surface erosion and every 30 days for inactive construction projects. The inspection must determine if there is evidence of, or the potential for, pollutants entering the drainage system, and BM Ps should be reviewed to determine if they still meet the design and operational criteria in the SWMP Plan and that they continue to adequately control pollutants at the site. The construction site perimeter, disturbed areas, discharge points and areas used for material storage that are exposed to precipitation shall be inspected for evidence of, or the potential for, pollutants entering the storm drainage system. Erosion and sediment control measures identified in this SWPM Plan and on the construction plans shall be observed to ensure that they are operating correctly. Any other structural BMPs that may require maintenance, such as secondary containment around fuel tanks or the conditions of spill response kits shall also be inspected. Stormwater items to be inspected include the following: 9 Condition & failures of structural & non-structural BMPSs COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN • Perimeter and outfall structure • Evidence of spills, upsets & discharges • Maintaining accurate SWMP Plan documentation • Material Handling and storage • Good Housekeeping • Site Stabilization • Meet authorities during inspections • Update permit disturbed acreage • Equipment and vehicle storage area • Maintenance records of equipment, systems & operations The project site and the adjacent streets impacted by the construction shall be kept neat, clean and free of debris. The control measures and facilities need to be maintained in good working order. Any items that are not functioning properly or are inadequate should be promptly repaired or upgraded. The site shall be inspected by responsible personnel who are familiar with the site. Inspection and monitoring will follow the procedures outlined below: Minimum Monitoring (Inspection) Requirements: • Inspections of the construction site shall be conducted by the contractor (or agent) every two weeks and after significant storm events. • The qualified site superintendent familiar with this SWMP Plan /BMP shall perform the inspections. • The contractor shall certify the site is in compliance with the SWMP Plan/BMP and the permit by: o Ensuring that areas contributing significant storm water discharges related to the construction activities have been identified. o Evaluating preventive measures required by the SWMP Plan /BMP to insure they are adequate and has been properly implemented. o Points of discharge from the site will be inspected to check for signs of pollutant discharge. o Certifying the grade elevations and capacity of permanent sedimentation facilities. o Determining if additional control measures will need to be implemented. o Updating this SWMP Plan if new measures are implemented or existing controls are deleted. Based on the results of the inspection, the description of potential pollutant sources, and the pollution prevention and control measures that are identified within this plan shall be revised and modified as appropriate and as soon as practicable after such inspection. Typically corrective action shall commence immediately when a deficiency is observed. COLLEGE & TRILBY STORMWATER MANAGEMENT PLAN In addition to the inspections performed at least every 7 days, several daily inspections will be required. Each day when any type of construction activity has taken place onsite, qualified personnel provided by the General Contractor shall: • Inspect all onsite areas where petroleum products are stored, used or handled for spills and leaks from vehicles and equipment. • Inspect all onsite locations where vehicle enter or exit the site for evidence of offsite sediment tracking. 5.2. Final stabilization and long term stormwater management Permanent stabilization will be achieved by establishing a vegetative cover on all disturbed areas.The vegetative cover will be as specified on the Landscape Plan. Final stabilization shall be considered complete when all paving and landscaping are completed and the vegetative cover has been established with a density of at least 70 percent of pre-disturbance levels (including shrubs and trees). In general seeding between spring and fall is encouraged whenever possible. Temporary and permanent seeding shall be completed within 14 days after grading has ceased and left to idle for more than 30 days. Care should be taken to complete seeding activities prior to November 1st for disturbed land intending to remain inactive for the winter months. Roughening and scarifying disturbed areas is allowed as a temporary stabilization with the following conditions: • During winter activity • Intended to seeded in the spring fall seasons • Intended to be active within 2-3 months of inactivity (with Stormwater approval) Management of storm water after completion of construction will be accomplished by utilizing the practices listed below: • Upon completion of construction, the site shall be inspected to ensure that all equipment, waste materials, and debris have been removed. • The site will be inspected to make certain that all graded surfaces have been landscaped or seeded with an appropriate ground cover. • Upon acceptance of final stabilization measures, all temporary BMP's shall be removed and proper function of inlets, drainage ways, or other storm water conveyance elements shall be restored. COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN • The storm sewer systems and the detention pond will be returned to full capacity and the outlet structures will be checked to assure they are unclogged and in working order. The General Contractor shall be responsible for maintaining the storm water controls in good working order including removal measures until the Inactivation Notice is filed with the State. The state requires the Inactivation Notice be filed within 3 months of the proposed end of construction. Alternatively, permit responsibilities may be transferred or reassigned by submitting a Notice of Transfer and Acceptance of Terms or a Reassignment of Coverage if control of a portion of the site changes parties. 6.0 CONCLUSION This Stormwater Management Plan has been prepared in accordance with the criteria and methods described in the "State of Colorado General Permit Application and Stormwater Management Plan Guidance for Stormwater Discharges Associated with Construction Activity." The drainage system has been designed to comply with the regulatory requirements of the City of Fort Collins Stormwater Criteria Manual. All temporary and permanent erosion and sediment control BMPs shall be inspected, maintained and repaired by the General Contractor as needed to ensure continued performance of their intended function. The General Contractor shall remove all temporary erosion and sediment control BMPs after stabilization is achieved or after temporary BMPs are no longer needed. Trapped sediment will be removed by the General Contractor or stabilized onsite. Disturbed soil areas resulting from removal of BMPs or the General Contractor will permanently stabilize vegetation as soon as possible. COLLEGE &TRILBY STORMWATER MANAGEMENT PLAN 7.0 REFERENCES 1.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D)and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential)when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential)when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

City of Fort Collins-GIS Appendix F: Construction Control Measures Standard Notes FORT COLLINS STORMWATER CRITERIA MANUAL Appendix F Standard Erosion Control Notes General Erosion Control Requirements These notes are a summary for the legal requirements, that are set forth in the Fort Collins Stormwater Criteria Manual (FCSCM), and that any conflict is resolved by the more stringent requirement controlling. 1) The Property Owner, Owner's Representative, Developer, Design Engineer, General Contractor, Sub-contractors, or similar title for the developing entity (here after referred to as the Developer) has provided these Erosion Control Materials in accordance with Erosion Control Criteria set forth in the Manual as an attempt to identify erosion,sediment,and other potential pollutant sources associated with these Construction Activities and preventing those pollutants from leaving the project site as an illicit discharge. Full City requirements and are outlined and clarified in the Manual under Chapter 4: Construction Control Measures and should be used to identify and define what is needed on a project. 2) The Developer shall make themselves thoroughly familiar with the provisions and the content of the specifications laid out in the Manual,the Development Agreement,the Erosion Control Materials compiled for this project, and the following notes as all these materials are applicable to this project. 3) The Developer shall implement and maintain Control Measures for all potential pollutants from the start of land disturbing activities until final stabilization of the construction site. 4) The City Erosion Control Inspector shall be notified at least twenty-four (24) hours prior to the desired start of any construction activities on this site to allow adequate time for on-site confirmation (initial inspection which can take up to two business days after receiving the request) that the site is in fact protected from sediment and pollutants discharges off site. Please contact erosion@fcgov.com early to schedule those Initial Erosion Control Inspections well in advance so that demolition, clearing, grubbing, tree removal, and scraping may begin without delay. Failure to receive an on-site confirmation before construction activities commence is an automatic "Notice of Violation" and can result in further enforcement actions. 5) The Developer shall proactively provide all appropriate Control Measures to prevent damage to adjacent downstream and leeward properties. This includes but is not limited to: trees, shrubs, lawns,walks, pavements, roadways,structures, creeks,wetlands,streams, rivers, and utilities that are not designed for removal, relocation, or replacement in the course of construction. 6) At all times the Developer shall be responsible to ensure adequate Control Measures are designed, selected, installed, maintain, repaired, replaced, and ultimately removed in order City of �,.F�t�l�1S Page 1 FORT COLLINS STORMWATER CRITERIA MANUAL Appendix F to prevent and control erosion suspension, sediment transportation, and pollutant discharge as a result of construction activities associated with this project. 7) All applicable Control Measures based upon the sequencing and/or phasing of the project shall be installed prior to those construction activities commencing. 8) As dynamic conditions (due to the nature, timing, sequence, and phasing of construction) in the field may warrant Control Measures in addition, or different, to what is shown on these plans,the Developer shall at all times be responsible to implement the Control Measures that are most effective with the current state and progress of construction. The Developer shall implement whatever measures are determined necessary, and/or as directed by the City Erosion Control Inspector.The Developer shall insure that all Erosion Control Plans (Maps) or SWMP documents are updated to reflect the current site conditions, with updates being initialed and dated.These site inspections and site condition updates shall be made available upon request by the City. 9) All listings, provisions, materials, procedures, activities, site work and the like articulated in this or other written site-specific documents (Including but not limited to the erosion control reports, development agreements, landscape, and drainage materials) shall meet or exceed the most restrictive language for City, County, State, and Federal regulations with regards to erosion, sediment, pollutant, and other pollution source Control Measures. The Developer shall be responsible to comply with all of these aforementioned laws and regulations. 10) The Developer shall ensure that all appropriate permits (CDPS General Permit Stormwater Discharges Associated with Construction Activity, Dewatering, Clean Water Act, Army Corps of Engineers' 404 Wetlands Mitigation Permit, etc.) have been attained prior to the relevant activity has begun.These permits or copies shall be made available upon request by the City. 11) The Developer shall furnish all conveniences and assistances to aid the Erosion Control Inspectors of materials, workmanship, records, and self-inspections, etc. of the Control Measures involved in the construction activities. 12) The Developer shall request clarification of all apparent site construction issues that may arise due to inconsistencies in construction plans for the site or site conditions around the selected Control Measures by contacting the Erosion Control Inspector. The Erosion Control Inspector will not be responsible for any explanations, interpretations, or supplementary data provided by others. 13) All Control Measures shall be installed in accordance with the Manual. 14) The City reserves the right to require additional Control Measures as site conditions warrant, to the extent authorized by relevant legal authority. 15) As with any construction standards, occasions may arise where the minimum erosion control standards are either inappropriate or cannot be justified. In these cases, a variance to these City of �,.F�t�l�1S Page 2 FORT COLLINS STORMWATER CRITERIA MANUAL Appendix F standards may be applied for pursuant to the terms, conditions, and procedures of the Manual. 16) Inspection. The contractor shall inspect site pollutant sources and implement Control Measures at a minimum of once every two weeks during construction and within 24 hours following a precipitation event. Documentation of each inspection shall be recorded and retained by the contractor. 17) All temporary Control Measures shall be cleaned, repaired, or reconstructed as necessary in order to assure continual performance of their intended function. All retained sediments, particularly those on paved roadway surfaces, shall be removed and disposed of in a manner and location so as not to cause their release into any drainage way. 18) Any Control Measure may be substituted for another standard Control Measure so long as that Control Measure is equal to, or of greater protection than the original Control Measure that was to be used in that location. (ex. silt fence,for wattles, or for compact berms) Wattle alone on commercial construction sites have shown to be an ineffective substitute for silt fence or compact berms unless it is accompanied by a construction fence to prevent vehicle traffic. 19) Any implementation or replacement of existing Control Measures for a non-standard control, or alternative Control Measure, shall require the review and acceptance by the City erosion control staff before the measure will be allowed to be used on this project. These Control Measures' details shall be submitted, reviewed and accepted to be in accordance with the Erosion Control Criteria based upon the functionality and effectiveness in accordance with sound engineering and hydrological practices Land disturbance,Stockpiles, and Storage of Soils 20) There shall be no earth-disturbing activity outside the limits designated on the accepted plans. Off road staging areas or stockpiles must be preapproved by the City. Disturbances beyond these limits will be restored to original condition. 21) Pre-disturbance vegetation shall be identified, protected, and retained wherever possible. Removal or disturbance of existing vegetation shall be limited to the area required for immediate construction operations,and for the shortest practical period of time.This should include sequencing and phasing construction activities in a way so that the soil is not exposed for long periods of time by schedule or limit grading to small areas. This should also include when practical advancing the schedule on stabilization activities such that landscaping takes place shortly if not immediately after grading has occurred. Vegetation efforts shall start as soon as possible to return the site to a stabilized condition. Sensitive areas should avoid clearing and grading activities as much possible. City of �,.F�t�l�1S Page 3 FORT COLLINS STORMWATER CRITERIA MANUAL Appendix F 22) All exposed soils or disturbed areas are considered a potential pollutant and shall have Control Measures implemented on the site to prevent materials from leaving the site. 23) All soils exposed during land disturbing activity (stripping, grading, utility installations, stockpiling, filling, etc.) shall be kept in a roughened condition at all times by equipment tracking, scarifying or disking the surface on a contour with a 2 to 4 inch minimum variation in soil surface until mulch,vegetation, and/or other permanent erosion control is installed. 24) No soil stockpile shall exceed ten (10)feet in height.All soil stockpiles shall be protected from sediment transport through the use of surface roughening, watering, and down gradient perimeter controls. All soil stockpiles shall be protected from sediment transport by wind in accordance with Municipal Code §12-150. All stockpiles shall be flattened to meet grade or removed from site as soon as practical, and no later than the completion of construction activities or abandonment of the project. All off-site stockpile storage locations in City limits shall have a stockpile permit from the City Engineering Department prior to using the area to store material. If frequent access from hardscape to the stockpile is needed a structural tracking Control Measure shall be implemented. 25) All required Control Measures shall be installed prior to any land disturbing activity (stockpiling, stripping, grading, etc.). All of the required erosion Control Measures must be installed at the appropriate time in the construction sequence as indicated in the approved project schedule, construction plans, and erosion control report. 26) All inlets,curb-cuts,culverts, and other storm sewer infrastructure which could be potentially impacted by construction activities shall be protected with Control Measures. Material accumulated from this Control Measure shall be promptly removed and in cases where the protection has failed,the pipes shall be thoroughly cleaned out. 27) All streams, stream corridors, buffers, woodlands, wetlands, or other sensitive areas shall be protected from impact by any construction activity through the use of Control Measures. 28) All exposed dirt shall have perimeter control.Any perimeter controls that drain off or has the ability to be tracked onto the nearby hardscape shall have some form of effective sediment control as the, or as part of the, perimeter control. 29) All exposed slopes should be protected.All exposed steep slopes(Steeper than 3:1 H:V) shall be protected from erosion and sediment transport through use of Control Measures. 30) No soils shall remain exposed by land disturbing activity for more than thirty (30) days after activity has ceased before required temporary seeding or permanent erosion control (e.g. seed/mulch, landscaping, etc.) is installed. This is not just limited to projects that are abandoned; this includes any project that is temporarily halted and no immediate activity is to resume within the next thirty (30) days, unless otherwise approved by the City Erosion Control Inspector. During a season when seeding does not produce vegetative cover,another City of �,.F�t�l�1S Page 4 FORT COLLINS STORMWATER CRITERIA MANUAL Appendix F temporary erosion control shall be implemented with or until temporary seeding or permanent erosion control can be performed. 31) All individual lots shall have effective sediment controls located on the street side and any down gradient side. Typically most lots drain to the front yet on those cases where houses are along a pond or drainage swale have the lot drain in a different direction than the street, those individual lots will need protection on that down gradient side to prevent sediment from leaving the lot. See the Individual Lot Details for further clarification. Vehicle Tracking 32) At all points where vehicles exit or leave the exposed dirt area on to a hardscape or semi hardscape (concrete, asphalt, road base, etc.) shall have installed at least one structural tracking Control Measure to prevent vehicle tracking.All areas not protected by an adequate perimeter control shall be considered a point where vehicles exit the site. Access points should be limited to as few entrances as possible (All perimeter areas shall be protected from tracking activities). 33) In all areas that the structural tracking Control Measures fail to prevent vehicle tracking, collection and proper disposal of that material is required.All inlets located near access points and affected by tracking activities shall be prevented from the introduction of sediment into the drainage system. 34) City Municipal Code §20-62, among other things, prohibits the tracking, dropping, or depositing of soils or any other material onto city streets by or from any source. City Municipal Code, §26-498, among other things, prohibits the discharge of pollutants on public or private property if there is a significant potential for migration of such pollutant.Therefore, all tracked or deposited materials(intentional or inadvertent)are not permitted to remain on the street or gutter and shall be removed and legally disposed of by the Developer in a timely and immediate manner. Dirt ramps installed in the curb-lines are not exempt to these sections of code and shall not be permitted in the street right of way(public or private). 35) If repeated deposit of material occurs on a site, additional structural tracking controls may be required of the Developer by the City Erosion Control Inspector. Loading and Unloading Operations 36) The Developer shall apply Control Measure to limit traffic (site worker or public) impacts and proactively locate material delivered to the site in close proximity to the work area or immediately incorporated in the construction to limit operational impacts to disturbed areas, vehicle tracking, and sediment deposition that could impact water quality. City of �,.F�t�l�1S Page 5 FORT COLLINS STORMWATER CRITERIA MANUAL Appendix F Outdoor Storage or Construction Site Materials, Building Materials, Fertilizers,and Chemicals 37) Any materials of a non-polluting nature (steel, rock, brick, lumber, etc.) shall be inspected for any residue coming off the material during routine inspection and will generally be located where practical at least fifty(50)feet from any permanent or interim drainage ways. 38) Any high environmental impact pollutant materials that have a high likelihood to result in discharge when in contact with stormwater (lubricants, fuels, paints, solvents, detergents, fertilizers, chemical sprays, bags of cement mix, etc.) should not be kept on site where practical. When not practical, they should be stored inside (vehicle, trailer, connex, building, etc.) and out of contact with stormwater or stormwater runoff. Where not available, they shall be stored outside in a raised (high spots or on pallets), covered (plastic or tarped), and sealed (leak proof container) in secondary containment location.The secondary containment or other Control Measure shall be adequately sized, located,where practical,at least fifty(50) feet from any permanent or interim stormwater structures or drainage ways and shall be monitored as part of the routine inspections. Vehicle and equipment maintenance and fueling 39) Parking, refueling, and maintenance of vehicles and equipment should be limited in one area of the site to minimize possible spills and fuel storage areas.This area shall be located,where practical, at least fifty (50) feet from any permanent or interim stormwater structures or drainage ways and shall be monitored as part of the routine inspections. All areas shall keep spill kits and supplies close. Significant Dust or Particulate generating Process 40) The property must be actively preventing the emission of fugitive dust at all times during construction and vegetation activities. All land disturbing activities that result in fugitive dust shall be in accordance with Municipal Code §12-150 to reduce the impacts to adjacent properties and community health.All required practices shall be implemented and additional ones shall be followed. These practices include watering the sites and discontinuing construction activities until the wind subsides as determined by any City Inspectors. Concrete truck / equipment washing, including the concrete truck chute and associated fixtures and equipment 41) All concrete and equipment washing shall use structural Control Measures appropriate to the volume of wash and frequency of use. These Control Measures shall be located, where practical, at least fifty (50) feet from any permanent or interim stormwater structures or drainage ways and shall be monitored as part of the routine inspections.These areas shall be clearly identified and protected from any wash from leaving the Control Measure. If frequent City of �,.F�t�l�1S Page 6 FORT COLLINS STORMWATER CRITERIA MANUAL Appendix F access from hardscape to the Control Measure is to occur, a structural tracking Control Measure shall be implemented.These Control Measures shall be frequently cleaned out. 42) The Developer is responsible for ensuring washing activity is taking place at the appropriate Control Measure and site workers are not washing or dumping wash water on to the dirt or other uncontrolled locations. Dedicated Asphalt and concrete batch plants 43) Dedicated asphalt and concrete batch plants are not acceptable on construction sites within the City of Fort Collins without an expressed written request and plan to reduce pollutants associated with that type of activity and approval by the City of Fort Collins specifically the Erosion Control Inspector. The Developer shall inform the erosion control inspection staff of any dedicated asphalt, or concrete batch plants that is to be used on site. Concrete Saw Cutting Materials 44) Saw cutting material shall be in accordance with Municipal Code §12-150 for air emissions and all water applications to the saw cutting shall prevent material from leaving the immediate site and collected.These cutting locations, once dried, shall be swept and scraped of all material and shall have proper and legal disposal. Waste Materials Storage and Sanitary Facilities 45) Trash, debris, material salvage, and/or recycling areas shall be, where practical, at least fifty (50)feet from any permanent or interim stormwater structures or drainage ways and shall be monitored as part of the routine inspections.These facilities should be located out of the wind and covered as able. Where not able to cover, locating said areas on the side of other structures to reduce exposure to winds, and follow maximum loading guidelines as marked on the container. The Developer is required to practice good housekeeping to keep the construction site free of litter, construction debris, and leaking containers. 46) Sanitary facilities shall be prevented from tipping through the use of anchoring to the ground or lashing to a stabilized structure.These facilities shall also be located as far as practical from an inlet,curb cut,drainage swale or other drainage conveyances to prevent material transport from leaving the local area.This consists of the facility being located, where practical, at least fifty (50) feet from any permanent or interim drainage ways. Other Site Operations and Potential Spill Areas 47) Spills: For those minor spills that; are less than the State's reportable quantity for spills, stay within the permitted area, and in no way threaten any stormwater conveyance, notify the City of �,.F�t�l�1S Page 7 FORT COLLINS STORMWATER CRITERIA MANUAL Appendix F City of Fort Collins Utilities by email at erosion@fcgov.com or phone (970) 817-4770. For any significant, major, or hazardous spills, notify the City of Fort Collins Utilities by phone only after Emergency Response(911) has been notified and is on route,County Health Department (LCDHE) has been notified through Larimer County Sheriff Dispatch (970) 416-1985, and the State Spill Hotline Incident Reporting have been contacted 1-877-518-5608. Written documentation shall be provided to the City within 5 days of the event. All spills shall be cleaned up immediately. 48) Selection of"plastic welded" erosion control blankets shall not be used in areas that wildlife, such as snakes, are likely to be located as these have proven to cause entrapment issues. Final stabilization and project completion 49) Any stormwater facilities used as a temporary Control Measure will be restored and storm sewer lines will be cleaned upon completion of the project and before turning the maintenance over to the Owner, Homeowners Association (HOA), or other party responsible for long term maintenance of those facility. 50) All final stabilization specifications shall be done in accordance with the Manual, Chapter 4: Construction Control Measures. 51) All disturbed areas designed to be vegetated shall be amended, seeded & mulched, or landscaped as specified in the landscape plans within 14 working days of final grading. 52) Soil in all vegetated (landscaped or seeded) areas, including parkways and medians shall comply with all requirements set forth in Sections 12-130 through 12-132 of the City Municipal Code, as well as Section 3.8.21 for the City Land Use Code. 53) All seeding shall refer to landscaping plans for species mixture and application rates and depths requirements. 54) All seed shall be drilled where practical to a depth based upon the seed type. Broadcast seeding shall be applied at double the rate as prescribed for drill seeding and shall be lightly hand raked after application. Hydroseeding may be substituted for drill seeding on slopes steeper than 3(H):1(V) or on other areas not practical to drill seed and crimp and mulch. All hydroseeding must be conducted as two separate processes of seeding and tackification. 55) All seeded areas must be mulched within twenty-four (24) after planting. All mulch shall be mechanically crimped and or adequately applied tackifier. The use of crimped mulch or tackifier may require multiple re-applications if not properly installed or have weathered or degraded before vegetation has been established. Areas of embankments having slopes greater than or equal to 3H:1V shall be stabilized with an erosion mat or approved equal to ensure seed will be able to germinate on the steep slopes. During a season when seeding does City of �,.F�t�l�1S Page 8 FORT COLLINS STORMWATER CRITERIA MANUAL Appendix F not produce vegetative cover,another temporary erosion control shall be implemented along with, or until,temporary seeding or permanent erosion control can be performed. 56) The Developer shall warranty and maintain all vegetative measures for two growing seasons after installation or until seventy percent (70%) vegetative cover has been established, whichever is longer and meets all the Criteria outlined in the Fort Collins Stormwater Criteria Manual Chapter 4: Construction Control Measures. 57) The Developer shall maintain, monitor, repair, and replace any and all applicable Control Measures until final stabilization has been obtained. All Control Measures must remain until such time as all upstream contributing pollutant sources have been vegetated or removed from the site. When any Control Measure is removed, the Developer shall be responsible for the cleanup and removal of all sediment and debris from that Control Measure.At the point at which the site has been deemed stabilized and verified by City Erosion Control Inspector, all temporary Control Measures can then be fully removed. All measures shall be removed within 30 days after final stabilization is achieved. 58) The responsible party shall maintain and keep current all payments or related forms of security for the Erosion Control Escrow until 1) stabilization has been reached and 2) all Control Measures and/or BMPs have sediment materials collected and the Control Measure removed from the site.At that time the site will be considered completed and any remaining Erosion Control Escrow shall be returned to the appropriate parties.
