Introduction A. SWMP Objectives The objective of this Stormwater Management Plan (SWMP) for Bloom Park & Pool, is to identify the Best Management Practices (BMP’s) which, when implemented, will meet the requirements of the Colorado Department of Public Health & Environment, Water Quality Control Division. According to Appendix A of the State of Colorado General Permit Application and Stormwater Management Plan Guidance for Stormwater Discharges Associated with Construction Activity (2019) and the City of Fort Collins Storm Drainage Design Criteria, the SWMP goal is to, “describe appropriate controls and measures to improve water quality by reducing pollutants in storm water discharges and ensure compliance with the requirements of the storm water permit. The SWMP must be completed and implemented at the time the project breaks ground, and revised if necessary, as construction proceeds to accurately reflect the conditions and practices at the site.” The SWMP is a “living” document which should be modified and updated through the course of site construction to accurately reflect site conditions at all times. Pollutant sources should be continuously evaluated, BMP’s selected, documented, implemented, and pollutant sources re-evaluated (and the process continued). A current copy of the SWMP shall be kept onsite at all times. A person familiar with the SWMP and on-site construction activities and clean-up procedures should be designated as the SWMP Administrator for the site. The SWMP Administrator will be responsible for, but not limited to, inspections and inspection reports, personnel training, regulatory agency contact, SWMP implementation and revisions, field notebooks, and record keeping of employee activities, contacts, and notifications. Anticipated permitting required for construction on this project include applying for a state stormwater construction permit through the Colorado Department of Public Health and Environment (CDPHE). Specifically, the permit is known as the Construction Stormwater Discharge Permit (CSP) and is regulated under the Colorado Discharge Permit System (CDPS). The application process typically works as follows:  Determine Permit Need: Before applying for the CSP permit, it's important to determine if your construction project requires coverage under this permit. Construction activities that disturb one or more acres of land or are part of a larger common plan of development or sale may require coverage under the CSP permit.  Prepare Application Materials: Once you've determined that your project requires a CSP permit, you'll need to prepare the necessary application materials. This typically includes completing an application form provided by the CDPHE and providing project-specific information such as site plans, erosion and sediment control plans, and stormwater management plans.  Submit Application: Submit the completed application and all required materials to the CDPHE. The application process may vary depending on the specific requirements of the permit and the complexity of the project. Be sure to follow any instructions provided by the CDPHE and submit the application within the required timeframe.  Review and Approval: The CDPHE will review the application to ensure that it meets all requirements and complies with state regulations. This may include evaluating the proposed erosion and sediment control measures, stormwater management practices, and compliance with SWMP Bloom Park & Pool Fort Collins, CO 2 C24008 - Bloom Park & Pool Erosion Control Report water quality standards. The review process may take some time, so it's important to submit the application well in advance of the planned construction start date.  Permit Issuance: If the application is approved, the CDPHE will issue the CSP permit, outlining the conditions and requirements that must be followed during construction to minimize the impacts of stormwater runoff and protect water quality. The permit will specify any monitoring or reporting requirements, as well as any additional measures that may be necessary to ensure compliance with state regulations.  Compliance and Monitoring: Once the CSP permit is issued, the permittee is responsible for complying with all permit conditions and requirements. This may include implementing erosion and sediment control measures, conducting regular inspections, and submitting monitoring reports to the CDPHE as required by the permit. No additional permitting is anticipated for erosion control aspects of this project noting that if local groundwater is encountered then a state dewatering permit will be required to discharge offsite. Other references are found in the Appendix regarding some of the requirements, restrictions, and forms related to the SWMP. II. Site Location and Description Project LocationThe Bloom Development (referred herein as “the site”) is located north of State Highway 14 (Mulberry Street) and just west of Interstate 25. The site is located within the southwest half of Section 9, Township 7 North, Range 68 West of the 6th Principal Meridian in the City of Fort Collins, County of Larimer, State of Colorado. The site is located on the parcel of land # 8709229005 owned by “MULBERRY DEVELOPMENT LLC”. A vicinity map is shown with Figure 1. SWMP Bloom Park & Pool Fort Collins, CO 3 C24008 - Bloom Park & Pool Erosion Control Report Figure 1. Vicinity and Phase Map A. Description of Property Currently, the project site is partially developed with the adjacent roads to the south and west sides of the site already constructed. The park site is directly adjacent to Pond D, which sits just east of the site and is currently operational. There is an existing pump house on the eastern side of the site, which will be incorporated into the landscaping and design of the park. There is also an existing mail kiosk structure on the west side of the site which will be protected in place during the construction of this park. An existing storm line and associated easement is in the center of the site running east to west. This storm line conveys flows from previously constructed portions of the site with an outfall into the sand filter within Pond D. The historic use of the property was agriculture and farming and thus characterized as a tilled field. The site currently has been overlot graded and largely filled. Below is a detailed summary of the existing conditions: Ground Cover - The site is currently partially developed, with some existing structures and utilities therefore ground conditions can be characterized as bare native soils roughly graded to support the construction of the pumphouse and grading of Pond D. Grades – In general, the entire site drains to the south southeast. These grades are generally less than 1%, with a few localized areas that slope between 2-5%. Soil Type - According to the Natural Resources Conservation (NRCS) web soil survey and report, the site consists of Garret loam and Ascalon sandy loam soils of hydrologic soils groups Type B and C. SWMP Bloom Park & Pool Fort Collins, CO 4 C24008 - Bloom Park & Pool Erosion Control Report Soils are assumed type C/D for drainage purposes. A more detailed breakdown of these soils are as follows: Ascalon Loam Soil: Ascalon Loam soil in central Larimer County, Colorado, exhibits moderate resistance to wind erosion due to its composition and structure. With an average annual rainfall of approximately 14 to 16 inches, Ascalon Loam soil experiences varying erosion potential, primarily influenced by precipitation intensity and soil moisture content. During periods of heavy rainfall, Ascalon Loam soil may experience increased susceptibility to erosion, particularly in sloped areas or where vegetation cover is sparse. Effective management practices such as conservation tillage, contour farming, and maintaining vegetative cover can help mitigate erosion risks associated with rainfall events in Ascalon Loam soil. The erosion potential of Ascalon Loam soil due to wind action is generally low to moderate, with factors such as wind speed, duration, and soil moisture content influencing erosion rates. Garret Loam Soil: Garret Loam soil in central Larimer County, Colorado, is characterized by its susceptibility to both rainfall and wind erosion, owing to its texture and topographic factors. Despite an average annual rainfall of 14-16 inches, Garret Loam soil is prone to erosion during intense precipitation events, especially on exposed slopes or areas lacking adequate vegetative cover. Erosion potential in Garret Loam soil is exacerbated by its susceptibility to compaction, which reduces infiltration rates and increases surface runoff, leading to soil loss during heavy rainfalls. Wind erosion poses a significant challenge for Garret Loam soil, particularly in open and unsheltered areas where wind speeds are higher. Loose soil particles are easily entrained and transported by wind, contributing to soil degradation and loss. Implementing erosion control measures such as windbreaks, conservation tillage, and cover cropping is crucial for mitigating erosion risks associated with both rainfall and wind action in Garret Loam soil. Utilities – The site includes the existing storm sewer within property, which will be utilized in the drainage design of the park. Domestic water and sanitary sewers stubs have been provided along the west side of the site, south of the mail kiosk. There are utilities associated with the pump house including an electrical service, gas services, and associated irrigation lines. Natural gas, telephone, fiber, and electric are installed around the perimeter of the site on the west and south sides of the site. Storm Drainage / Irrigation Facilities – Storm Drainage / Irrigation Facilities – The site does contain storm drainage infrastructure previously designed for the greater subdivision include a detention pond, Pond D, located adjoining the eastern portion of the site. This stormwater detention pond and connected LID sand filter are operational. The upstream storm sewer is connected to a local street collection system. Groundwater – Groundwater was observed at depths of 10’ to 12’ below the general project site (Appendix D). Note that this site will generally be filled during the earthwork phase of construction. The project site is located within the Cooper Slough Drainage Basin as shown in Figure 2. The proposed site area consists of approximately 2.52 acres. Two (2) proposed roads that will be constructed as part of the Bloom 1st Filing Project and shown in the construction plans by Galloway engineering make up two SWMP Bloom Park & Pool Fort Collins, CO 5 C24008 - Bloom Park & Pool Erosion Control Report sides of the property - Aria way on the west and Sykes Drive to the south. The remaining two sides are bound by home lots to the north and Detention Pond D to the east The nearest receiving waters to the site are the Cooper slough drainage and wetlands (approximately 1,200 feet from the site) that flow into the Boxelder Creek, which further transports water to the Poudre River. Figure 2. Lower Cooper Slough Drainage Basin – As Shown on the City of Fort Collins Website The developed Bloom project site area includes the construction of a playground, park, pool and associated buildings and infrastructure, parking areas, and landscaped areas. The Bloom Park and Pool project is part of the Cooper Slough Basin whose ultimate outfall is Boxelder Creek, located south of Colorado Highway 14 (Mulberry Street). Runoff from the Park site will be captured using a combination of swale and storm sewer pipe to be conveyed to existing drainage infrastructure and off-site detention facility. Existing storm sewer traverses the site and is connected to the existing detention pond D. SWMP Bloom Park & Pool Fort Collins, CO 6 C24008 - Bloom Park & Pool Erosion Control Report Figure 3. General Site Layout - Bloom Park and Pool III. Sediment/Erosion Control The SWMP will be required to be updated by the Contractor at the time of development. The construction plans for the Bloom Mult-Family development will also be updated to include the SWMP administrator and contact information before construction begins. The general construction activities and BMP implementation is outlined as follows: Pond D LID SWMP Bloom Park & Pool Fort Collins, CO 7 C24008 - Bloom Park & Pool Erosion Control Report A. Construction Activity Description Construction activity (for all phases of construction) includes installation of BMP’s. Three primary phases of construction include an initial clearing and grubbing, demolition, and overlot grading phase. This phase will be followed by a utility and core infrastructure phase. This will be followed with a stabilization phase and building construction phase. B. Proposed Sequence for Major Activities Construction of the proposed Bloom Park and Pool site will take place with 1 phase (see Erosion Control/Phasing Map in Appendix A). The initial construction activities will begin with clearing and grubbing as well as topsoil removal (if present) and stockpiling. After the site has been cleared of existing vegetation and topsoil, grading will begin, which will include the installation of temporary erosion control measures. Once the site has been graded, the proposed utilities will be installed. Proposed utilities will include the installation of underground storm sewer systems (including pipe, manholes, inlets), and other site utilities for the project. Following the completion of utility installation subgrade preparation will occur and installation of hardscape areas will occur. Concrete curb and gutter as well as sidewalks will be installed followed by paving of the parking areas and access roads. After infrastructure improvements are complete, all remaining disturbed areas of the site will be re-seeded to minimize any erosion potential as well as to help eliminate the transport of sediment or pollutants located on the property. Listed below are the major aspects of construction in the anticipated order for the project: 1.) Initial Erosion Control Measures Installed. 2.) Clearing and grubbing of the site. 3.) Topsoil removal and stockpile. 4.) Grading 5.) Install additional erosion control measures as needed, maintenance of existing control measures. 6.) Installation of utilities – open trenching and installation of proposed utility pipelines and structures/junctions for storm sewer, sanitary sewer and water infrastructure located on the site. 7.) Install additional erosion control measures for storm sewer facilities, maintenance of existing control measures. 8.) Subgrade preparation / final grading of the site in preparation for building pads, and hard surfaces. 9.) Installation of concrete curb and gutter, drainage pans, sidewalks, miscellaneous concrete pads and walkways, asphalt paving, and building pads. 10.) Install additional erosion control measures based on these hard surface improvements and changes in drainage paths, maintenance of existing control measures. 11.) Installation of project lighting as well as required hard surface striping. 12.) Revegetation efforts and stabilization of remaining disturbed areas on the site begins. Work will include seeding, mulching, installation of sod, and installation of other natural landscape features provided in the landscaping plan. 13.) Permanent erosion control measures installed; temporary control measures removed. 14.) Final site cleanup and punch list items addressed. SWMP Bloom Park & Pool Fort Collins, CO 8 C24008 - Bloom Park & Pool Erosion Control Report Infrastructure construction is estimated to begin in the late spring of 2025 and be completed by Fall 2025. C. Important Site Areas and Volumes The total area of the project is 2.52 acres which will be developed into one construction phase. Table 1. Phasing and Earthwork Area Staging/Stockpiling Area (Ac.) Existing Imperviousness (%) Topsoil Volume (CY) Area of Disturbance (Ac.) Net adjusted, required import of materials with 15% compaction factor (CY) Phase 1 2.52 0.10 2 645 2.40 3,900 D. Potential Pollutant Sources Listed below are potential pollutant sources that are expected on the site as well as means and methods to contain and eliminate chances of these sources to be transported off site and to downstream receiving waters. 1.) Disturbed and Stockpiled Topsoil: Stockpiled soils generated from grading and utility excavation as well as topsoil stockpiles will be stored in designated areas for each phase of the project. These stockpile piles shall not exceed 10 feet in height and shall be located at minimum 50’ away from any proposed or existing storm inlets or from the proposed-on site detention pond. If these stockpiled soil piles are anticipated to remain for greater than 30 days, they shall be temporarily seeded. Silt fence or straw waddles shall be installed around the perimeter of the stockpiles in order to prevent rainfall events from transporting sediment away from the stockpiles. Disturbed areas of the site shall be surface roughened to prevent heavy erosion. Locations for proposed staging / stockpiling areas can be found in Appendix C as part of the interim erosion control plan. 2.) Vehicle tracking of sediments: It is anticipated that the contractor will access the property from Lions Gate Drive. A Vehicle tracking control pad will be required at this access location onsite during construction to reduce tracking sediment onto the adjacent streets. At the end of each workday, the Contractor shall sweep or scrape Lions Gate Drive of sediment that may have accumulated during the workday. 3.) Management of contaminated soils: There are not any known contaminated soils on the site. However, if the contractor encounters contaminated soils during the construction process, they should stop construction immediately and notify the appropriate government authorities in accordance with good construction safety and practice. SWMP Bloom Park & Pool Fort Collins, CO 9 C24008 - Bloom Park & Pool Erosion Control Report 4.) Loading and Unloading operations: Loading and unloading will take place on the site. Truck access should be limited to the extent possible to locations within the disturbed limits of the project. BMP’s such as silt fence in non- paved areas and rock socks in paved areas should be placed to keep sediment from exiting the disturbed area limits, primarily towards the East as this is the low side of the site. 5.) Outdoor storage activities (building materials, fertilizers, chemicals, etc.): Storage of onsite materials including building materials, fertilizers, waterline, and sanitary sewer will be covered and placed on pallets to prevent direct contact with the ground and potential surface runoff. 6.) Vehicle and equipment maintenance: Vehicle and equipment maintenance should be performed offsite or onsite within an area surrounded by silt fence or straw wattles. Vehicle and equipment maintenance shall not happen along the adjacent public streets. At a minimum, all vehicle and equipment maintenance shall be performed on the hard surface or gravel areas at least 50’ from any stormwater feature (i.e. inlet, storm sewer, concentrated runoff, swale, etc.) 7.) Significant dust or particulate generating processes: The Contractor shall comply with the applicable air pollution control requirements of the City of Fort Collins. The Contractor shall take appropriate actions to minimize atmospheric pollution and take reasonable precautions which shall include, but not be limited to: 1. The use of water for control of dusts for construction processes such as demolition, grading, or the clearing of land. 2. Covering, always when in motion, open-bodied trucks transporting materials likely to give rise to airborne dusts. 3. Require lower speeds for vehicles entering, exiting, and driving within the project limits to minimize the amount of dust disturbed by moving vehicles. 8.) Routine maintenance activities involving fertilizers, pesticides, detergents, fuels, solvents, oils, etc.; Chemicals, fuels, lubricants, and paints stored on-site will be in watertight containers and covered as necessary and stored in a bermed area, a storage building, or within a vehicle to act as secondary containment. 9.) On-site waste management practices (waste piles, liquid wastes, dumpsters, etc.); 1. Waste piles should be covered or surrounded by silt fence or straw wattles. Liquid wastes should be collected and stored in covered containers and disposed of properly. 2. Solid waste materials, including disposable materials incidental to the major construction activities, will be collected in on site dumpsters. The containers will be emptied periodically and trucked away from the site. Dumpsters should have covers. 10.) Concrete truck / equipment washing, including the concrete truck chute and associated fixtures and equipment: A dedicated concrete washout area is necessary for this project. The contractor shall clean out equipment within the washout area so that runoff is not allowed to leave site and enter the public streets or neighboring properties. For this project, the location of the concrete washout may have to be relocated several times depending on construction sequencing and location. SWMP Bloom Park & Pool Fort Collins, CO 10 C24008 - Bloom Park & Pool Erosion Control Report 11.) Dedicated asphalt and concrete batch plants: There will not be dedicated asphalt or concrete batch plants on this site. 12.) Non-industrial waste sources such as worker trash and portable toilets: Worker’s trash shall be disposed of in an onsite dumpster. The site should be free of trash at the end of each working day. Portable toilets shall be utilized by construction personnel and serviced regularly by a commercial operator. They shall be located a minimum of 5 feet from the curb or 50 feet from inlets. If sanitary facilities are located on a paved surface, toilets shall be equipped with a containment pan or a secondary containment BMP. Regardless of location all portable toilets shall be anchored per manufacturer recommendations. 13.) Saw cutting and Grinding: Cutting of pavement or concrete and milling of asphalt is expected to occur during the project for tie in locations of proposed access roads and utilities. These are not on the project property and will be part of city ROW. Nevertheless, water suppression shall be used to reduce transport of dust during operations. Loose material shall be removed and disposed of off-site at a proper facility. 14.) Non-Storm Water Discharge: Other non-storm water components of discharge include, but are not limited to, water line flushing, irrigation to establish seeding. It is important for the contractor to manage the runoff from these items utilizing the BMP’s mentioned in this report (i.e. silt fence, straw waddles, concrete washout areas, surface roughening, etc.). E. Water Quality Treatment and LID Practices Water quality for the site was included with the initial Filing 1 infrastructure phase. No additional features are included within the site. F. Erosion and Sediment Controls Once construction activity begins, Best Management Practices (BMP’s) intended to contain sediment onsite must be constructed, inspected, and repaired as necessary. Such controls must be functional before upslope land disturbance takes place. The BMP’s will be installed as shown on the SWMP Map shown in Appendix A. They must be supplemented as on-site experience proves necessary in order to control sediment, pollutant discharge, and ensure public safety. The following temporary and permanent BMP’s will be installed and maintained to control on-site erosion and prevent sediment from traveling off-site during construction. Temporary Control Measures (BMPs)  Inlet Protection is a temporary BMP that helps prevent soil and debris from the site from entering the storm drain inlets and usually consists of a sediment filter around or upstream of the storm drain inlet. Inlet protection allows storm water to flow into the drain but only after SWMP Bloom Park & Pool Fort Collins, CO 11 C24008 - Bloom Park & Pool Erosion Control Report excess sediment has been filtered out. Inlet protection will be used on existing and proposed storm inlets and will be installed at such time as construction of the storm sewer system occurs. Inlet protection for this site will consist of:  Regular Meetings are a temporary and non-structural BMP. Regular meetings with on-site workers including builders, suppliers, landscape personnel, etc. should be conducted so that they are kept up to date with site standard operating procedures.  Silt Fence is a woven synthetic permeable fabric that filters runoff. Silt fence is a temporary barrier that is installed prior to earthmoving activities and is placed downstream of areas where runoff from construction activities is expected to occur, especially along the site perimeter to allow sediment to settle from runoff before water leaves the construction site. Silt fences will be installed per manufacturer’s recommendations. Silt fence encourages sheet flow and is not intended to be used in areas of concentrated flow. If concentrated flow is encountered during the placement of the fence, an alternative BMP shall be used and the SWMP should be updated to reflect this change.  Staging Areas will be provided during the construction process at least 100’ from any storm water conveyance. Staging areas include locations for vehicle fueling, concrete truck washout, material storage and transfer, equipment maintenance and cleaning, and other construction activities. These areas will be maintained as isolated locations that allow for contaminants to be concentrated and removed from the site as necessary. Concrete washout areas shall be designed such that washout water cannot leave the location, nor shall storm water runoff wash concrete from the locations.  Straw Wattles are a temporary BMP that are used for a variety of purposes. They are used for inlet protection, curbside check dams, swale protection, at the bottom of slopes, or the limits of property boundaries. They are easy to install and are increasingly being used for Small Site SWMP’s. The straw wattles, which are meshed netting “tubes,” filled with straw, excelsior, or coconut fiber. Wattles for swale protection should be installed following rough grading of channel areas. Wattles require proper installation and maintenance to ensure their performance.  Rock Socks are a temporary BMP that are used for a variety of purposes. They are used for inlet protection, curbside check dams, or at the limits of property boundaries. Rock socks are wire meshed “tubes” filled with rocks. Rock Socks require proper installation and maintenance to ensure their performance.  Check Dams are a temporary BMP that are used as grade control structures in drainage channels to limit the erosive nature of stormwater by reducing flow velocity. Check dams are typically constructed from rock or gravel. Check dams require proper installation and maintenance to ensure their performance.  Street Sweeping and Vacuuming removes sediment that has been tracked onto roadways to reduce sediment transport into storm drain systems or a surface waterway. This practice should be used on the adjacent paved road to the construction site. Paved roads should be inspected on a daily basis and more frequently as needed.  Saw Cutting Pollution Prevention prevents dust and slurry from asphalt and concrete saw cutting activities from migrating into the existing storm drain system. Slurry and cuttings shall be vacuumed during cutting and surface operations and shall not be allowed to remain on pavement surface overnight. Collected slurry and cuttings shall be disposed of in a manner that does not violate groundwater or surface water standards.  Surface Roughening is provided following grading activities to slow the effects of wind erosion. Roughening can be used as a temporary BMP and is a technique used for creating unevenness SWMP Bloom Park & Pool Fort Collins, CO 12 C24008 - Bloom Park & Pool Erosion Control Report on bare soil through the construction of furrows (groove cuts) running across a slope or by utilization of construction equipment to track the soil surface. The primary function of surface roughening is to reduce erosion potential by decreasing runoff velocities, reducing the length of sheet flow trapping sediment, and increasing infiltration of water into the soil.  Temporary Seeding is the establishment of a temporary vegetative cover on a graded area that will be exposed for longer 30 days. Temporary seeding can be used on areas requiring temporary protection that will eventually need permanent vegetation at the completion of the construction or it can be used for areas that will be re-disturbed after a period of inactivity. The seed mix 100% smooth brome at a minimum application rate of 30 pls/lbs/acre. Fertilizer and Mulch shall be included as specified on the plans.  Temporary Erosion Control Fabric is comprised of a temporary degradable erosion control blanket designed to provide immediate erosion protection and vegetation establishment assistance on moderate slopes and low to medium-flow channels where bare-ground seeding and loose mulches often fail. Temporary erosion control blankets are being recommended moderate slopes that do not require permanent turf reinforcement matting.  Vehicle Tracking Control is a stabilized stone pad located at points of ingress and egress on a construction site and acts as a temporary BMP. The stone pad is designed to reduce the amount of mud transported onto public roads by construction traffic by removing mud and sediment from the vehicle’s wheels when it drives over the gravel pad. These areas are limited to the minimum number necessary to provide functional construction access and are installed prior to grading activities. Whenever the construction entrance exists onto a public road, the road shall be cleaned at the end of each day. Vehicle Tracking Control will also be used on this site at any stockpile area exits.  Wattle Sediment Protection is a temporary BMP that are typically used as check structures in areas of concentrated water flow such as swales, grassed waterways, and down drains. They can be installed in combination with any type of rolled erosion control blanket or channel liner and function by slowing water velocity, settling out sediment, and preventing undermining of the channel lining material. Wattles for swale protection should be installed following rough grading of channel areas. Sizing and spacing shall be per manufacturer’s recommendation.  Wind Borne Sediment and Dust Control measures will be provided during the construction process to control wind borne sediment. During grading activities, water will be applied to the disturbed soils for the purpose of maintaining cohesion with clay type soils and also to meet moisture requirements for compaction of disturbed soils. Other measures of mitigation for wind erosion may include the timely installation of seed and mulch following the establishment of final grade, and the timely installation of pavement following completion of utility trenching operations and curb construction. Open areas should be kept in a roughened condition (see Surface Roughening above). Permanent Control Measures (BMPs)  Grass-Lined Swales (included as part of permanent seeding or other permanently stabilized swales) are permanent landscaped channels constructed generally below grade to convey runoff or channel water to a desired location. The grass-lined areas allow for infiltration to occur as well as including a flow path across a vegetated surface slowing the conveyance rate of storm water runoff. SWMP Bloom Park & Pool Fort Collins, CO 13 C24008 - Bloom Park & Pool Erosion Control Report  Permanent Seeding and Planting is the establishment of a permanent perennial vegetation such as trees, shrubs, grasses/sod, or legumes on exposed areas for final permanent stabilization in order to provide stabilization of the soil by holding soil particles in place. Please reference the approved site landscaping plan for the permanent landscaping specified for this site. The project Site Plan includes landscape design and specifications that detail the location and installation of planting materials. See Appendix for the prescribed seed mix and verify any changes with final approved plans. Note the project landscaping includes a mix of gravel and crusher fine trails, boulders, native seed areas, native seed related to detention basins, irrigated sod grassed areas, shrub beds, and trees. Shrub beds have 3” to 4” of mulch as coverage. Specifications from the project landscape plan call out the following: o Topsoil: to the maximum extent feasible, topsoil that is removed during construction activity shall be conserved for later use on areas requiring revegetation and landscaping. o Soil amendments: soil amendments shall be provided and documented in accordance with city code section 12-132. The soil in all landscape areas, including parkways and medians, shall be thoroughly loosened to a depth of not less than eight(8) inches and soil amendment shall be thoroughly incorporated into the soil of all landscape areas to a depth of at least six(6) inches by tilling, discing or other suitable method, at a rate of at least three (3) cubic yards of soil amendment per one thousand (1,000) square feet of landscape area. Prior to the issuance of any certificate of occupancy, a written certification must be submitted to the city that all planted areas, or areas to be planted, have been thoroughly loosened and the soil amended, consistent with the requirements set forth in section 12-132.  Preservation of Existing Vegetation should occur where no construction activity is expected to occur. Preservation of natural vegetation is generally a permanent BMP and is applicable to construction sites with pre-existing vegetation. Only land needed for building activities and vehicle traffic needs is to be cleared. Due to the nature of this project, this BMP is not likely feasible.  Storm Sewer Outlet Protection devices are structurally lined aprons or other energy dissipating devices placed at the outlets of pipes or paved channel sections. Outlet protection devices prevent scour at storm water outlets and minimize the potential of downstream erosion by reducing the velocity of storm water flows. Turf reinforcement matting will be used downstream of storm sewer outfalls as pipe outlet protection. Outlet Protection is installed with the storm sewer construction and serves as a permanent structural BMP. G. Erosion Control Sequencing This project will have two Phases for construction each with three erosion control phases. These phases may overlap or be partially concurrent. Each transitional phase is proposed to include a site assessments. The initial erosion control sequence is the mobilization and installation of initial controls. SWMP Bloom Park & Pool Fort Collins, CO 14 C24008 - Bloom Park & Pool Erosion Control Report With the initial erosion control items installed, the next phase will consist of site demolition, grading activities and construction of the infrastructure (utilities, storm sewer, and development of landscaped areas). The final stage will include the construction of the site hard surfaces including roads, parking areas, curb and gutter, concrete sidewalk and island areas and finally ending in stabilization of all remaining disturbed areas of the site. Each of the phases is described in the follow section, including necessary erosion control items. A SWMP drawing is located in the Appendix that includes the minimum required BMP’s found on the Sediment and Erosion Control Plans. It should be filled in with the appropriate BMP’s as they are constructed/placed within the project site. Sequence 1 – Initial, Prior to Construction  Site Assessment - The goal of the site assessment is to identify areas of concern and assess the extent of erosion issues resulting from previous work on the site prior to starting a new activity.  Silt Fence – Before construction commencement, silt fence will be placed downstream of areas where runoff from construction activities is expected to occur.  Staging Area – A concrete wash out area, fueling area, and other staging areas will be provided during the construction process at least 100’ from any storm water conveyance. A staging area is to be shown on the SWMP drawing when its location is identified.  Vehicle Tracking Control – Before commencement of construction, vehicle tracking control shall be placed at the location shown west of Overland Trail along West Elizabeth Street. Any other points of ingress and egress planned by the contractor and approved by the owner shall also receive suitable vehicle tracking control BMP's.  Construction Fence – Before commencement of construction, construction fence shall be placed at the contractor’s discretion (or as shown in the plans) to limit access by construction equipment and personal vehicles to designated areas of ingress and egress.  Stage/stockpile Management – Designate stockpile/staging location per erosion control initial sequence map included in appendix A or amend if necessary. It is anticipated that Phase 2 will be used for stockpile during Phase 1 construction. Recommended BMP Installation: SWMP Bloom Park & Pool Fort Collins, CO 15 C24008 - Bloom Park & Pool Erosion Control Report Sequence 2 – Site Demolition, Site Grading, and Infrastructure Construction The items installed in sequence 1 shall be in place, functional, and maintained during and following the site demolition and site grading operations. In addition to those items, the following BMP’s shall be installed.  Site Assessment - The goal of the site assessment is to identify areas of concern and assess the extent of erosion issues resulting from previous work on the site prior to starting a new activity.  Wind Borne Sediment and Dust Control – Wind borne sediment and dust control measures should be implemented during grading activities. This will be particularly important to consider prior to the establishment of seeding.  Inlet Protection – Wattles will be placed at curb inlets and area inlets located throughout the site immediately after the inlet is constructed / installed. Existing inlets shall be protected prior to heavy equipment staging, demolition, or commencement of construction activities.  Swale Protection – Straw wattles and rock sock check dams will be placed within the swales immediately following rough grading. Wattles and check dams shall be placed across the swale for every 2’ of drop in swale elevation or every 300'. Note during utility installation remove and reset rock sock checks during utility pipe installation. Prior to Mobiliation •Site Assessment Mobilization •Construction Fencing •Tracking Control •Staging Area Prior to grading •Silt Fence - Perimeter Protection •Stockpile Management Grading SWMP Bloom Park & Pool Fort Collins, CO 16 C24008 - Bloom Park & Pool Erosion Control Report  Slope Protection – Surface roughening and contour furrows shall occur after rough grading.  Temporary Seeding – The majority of the landscaped areas will be permanently seeded or planted. However, if disturbed areas are left without permanent stabilization 30 days after grading, temporary seeding will be required.  Outlet Protection– Riprap and/or permanent turf reinforcement matting will be placed immediately downstream of storm sewer outfalls.  Concrete Washout Area – Concrete washout areas will be placed prior to, and maintained during, the completion of concrete work.  Inlet Protection – Wattles will be placed at curb inlets and area inlets located throughout the site immediately after the inlet is constructed / installed. Existing inlets shall be protected prior to heavy equipment staging, demolition, or commencement of construction activities.  Stage/stockpile Management – Use and monitor stockpile/staging location per erosion control as required during construction. Strip topsoil unclassified excavation and store at this location and be sure to surround the stockpile (s) with silt fence or straw wattles. Sequence 3 – Building, Site Improvements, finalized site construction. This sequence will likely begin before the seeding has been established throughout the site, so it is expected that majority of the BMP’s shown in Phase 1 and Phase 2 will be in place at the beginning of this phase. As roads are paved and seeding is established there will be previously placed BMP's such as vehicle tracking control devices and some sections Grading •BMP Maintenance •Wind borne and dust control •Swale Protection (as completed) •Slope protection (as required) Prior to Utility Installation •Site Assessment •Concrete washout •Rock Socks Utility Installation •Inlet protection •Outlet protection •Stockpile Management •Rock Socks SWMP Bloom Park & Pool Fort Collins, CO 17 C24008 - Bloom Park & Pool Erosion Control Report of silt fence that may be removed. There are other items such as inlet protection, silt fence, and swale protection that may only be removed after all construction is complete and upstream areas are established.  Site Assessment - The goal of the site assessment is to identify areas of concern and assess the extent of erosion issues resulting from previous work on the site prior to starting a new activity.  Permanent Seeding – Permanent seeding or landscaping shall be placed immediately in areas that are final graded and where little future disturbance is expected.  Inlet Protection – Wattles will be placed at curb inlets and area inlets located throughout the site immediately after the inlet is constructed / installed. Existing inlets shall be protected prior to heavy equipment staging, demolition, or commencement of construction activities. As areas reach stabilization, remove remaining temporary BMPs. H. Materials Handling and Spill Prevention The site development includes appropriate construction staging and stockpile areas identified on the SWMP Plans shown in Appendix A. Stormwater runoff generated from the staging areas will be routed to a temporary sedimentation area where runoff will be contained and filtered before being discharged downstream. The staging/stockpile area(s) may be moved to a location no closer than 100’ from a storm water conveyance. Vehicle tracking control should be placed at the stockpile area entrance/exit and silt fence should surround it. If relocated, the SWMP should be updated with the actual location of the stockpile/staging area(s). Prior to Surfacing Restoration •Site Assessment •removal of BMPS in conflict with paving (tracking pads, inlet protection, as required) Paving & Flatwork •Restore inlet protection directly after (if temporaily removed) Building Construction •Site Assessment •Final restoration (permanent seeding, surfacing) SWMP Bloom Park & Pool Fort Collins, CO 18 C24008 - Bloom Park & Pool Erosion Control Report Chemicals, fuels, lubricants, and paints stored on-site will be in water tight containers and covered as necessary and stored in a bermed area, a storage building, or within a vehicle to act as secondary containment. Storage of onsite materials including building materials, fertilizers, waterline, sanitary sewer, and storm sewer will be covered and placed on pallets to prevent direct contact with the ground and potential surface runoff. Concrete and asphalt batch plants are not anticipated on this site and thus are not included in this SWMP. In the event of a spill or accident, it shall be contained and disposed of so that it will not flow from the site or soak into the soil. Once construction is completed, concrete waste and contaminated soil will be disposed of properly. The SWMP Administrator should be notified of spills. Reporting Spills: Any spill or discharge of any pollutant, including but not limited to oil, paints, fuels, hazardous liquids, sediment, or super-chlorinated water that reaches storm drains or enters “Waters of the State” must be reported to the CDPHE Emergency Spill Reporting line at 1-877-518-5608. If a spill or leak is of a hazardous substance that exceeds 1 pint or is of an unknown substance of any amount, call 911 and notify the Colorado Department Public Health and Environment (CDPHE) 24-hour emergency spill notification hotline at 1- 877-518- 5608, immediately. If the spill is more than 25 gallons of a petroleum product from a regulated storage tank or delivery truck or any amount that causes a sheen on nearby surface water, it must be reported to the Division of Oil and Public Safety at the Colorado Department of Labor and Employment within 24 hours at (303) 318-8547 or to CDPHE Emergency Spill Reporting line at 1-877-518-5608 – if after normal business hours. If cleanup cannot be accomplished within 24 hours, the Division of Oil and Public Safety must be notified immediately. For non-emergency spills, call 970-674-2490. Spills shall also be reported to the onsite supervisor. I. Other Controls The following includes other measures to control pollutants:  Solid waste materials, including disposable materials incidental to the major construction activities, will be collected in containers. The containers will be emptied periodically and trucked away from the site. Dumpsters shall have covers.  Water used to establish and maintain grass, for dust control, and for other purposes during the construction phase must originate from a public water supply or private well approved by the Colorado Department of Public Health and Environment unless otherwise approved.  Sanitary facilities shall be provided at the site throughout construction activities. They shall be utilized by construction personnel and serviced regularly by a commercial operator. They shall be located a minimum of 5 feet from the curb or SWMP Bloom Park & Pool Fort Collins, CO 19 C24008 - Bloom Park & Pool Erosion Control Report 50 feet from inlets and must be anchored. If sanitary facilities are located on a paved surface, a secondary containment BMP will need to be constructed.  Access off paved roads should be limited. J. Final Stabilization and Long-term Stormwater Quality Final stabilization is reached when all soil disturbing activities at the site have been completed and vegetative cover has been established with a density of at least 70 percent of pre-disturbance levels or when equivalent permanent erosion reduction methods have been utilized. Upon final stabilization, temporary BMP’s may be removed, unless they are required to remain in place for future phasing. Water quality enhancements are provided with underground chambered detention system. A more detailed description of these features is outlined in Appendix C. In areas where grass-lined swales are provided for storm water conveyance. The soft bottom/overbank areas allow for infiltration to occur as well as including a flow path across a vegetated surface slowing the conveyance rate of storm water runoff. Temporary and Permanent seeding will be implemented on the site as well as other plantings that will be implemented based off the landscape architectural plan as required by the local jurisdiction where the site exists (City of Fort Collins). References to these plans are included in the appendix of this SWMP. These referenced have specific requirements for soil preparation, soils amendments and other requirements related to final landscaping installation on this site. K. Inspection and Maintenance Procedures Upon completion of each phase of construction, appropriate measures shall be taken to inspect and maintain existing erosion control features, as described herein or per manufacturers specifications (whichever is more stringent) and install new erosion control elements associated with each phase of construction. The temporary control measures will be inspected and documented at a minimum of once every 14 days and after each precipitation or snowmelt event. The SWMP will be kept up-to-date with inspection records, maintenance procedures, and changes. Records should include complete inspection reports for each inspection, maintenance, and/or repair. A record-keeping system is recommended in managing inspection and maintenance reports and should include all maintenance records, spill response, weather conditions, training, correspondence, etc. Preventative maintenance also involves the regular inspection and testing of equipment, timely maintenance of the equipment, and complete records of the maintenance and inspections of the equipment. The maintenance and inspection records should be kept on site and made available upon request. Inspections must include the observation of the construction site perimeter, runoff discharge points, disturbed areas, staging areas (including concrete washout areas and fueling areas), erosion and sediment control measures identified in this SWMP, and any other structural BMP’s SWMP Bloom Park & Pool Fort Collins, CO 20 C24008 - Bloom Park & Pool Erosion Control Report that may require maintenance. The inspection must determine if there is evidence of or potential for pollutants to enter the drainage system and if they should be modified, replaced, or added to. The following list includes some recommended maintenance procedures:  Erosion and sediment control measures determined, upon inspection, to be in need of repair shall be maintained before the next anticipated storm event or as necessary to maintain continued effectiveness of erosion and sediment control measures. If it is impractical to maintain erosion and sediment control measures before the next storm event, maintenance should be accomplished as soon as practical.  Locations where vehicles enter or exit the site shall be inspected for evidence of sediment being tracked off-site by construction traffic. Such sediment shall be removed before it can be conveyed to the receiving storm drains or creeks.  Seeded areas will be checked to see that grass coverage is maintained. Areas will be watered, fertilized, and reseeded as needed. The detailed soil preparation is outlined in previous sections of this SWMP and the referenced landscape plan in the appendix of this SWMP. Note confirm with final stamped plans for any changes of the landscape plan. IV. References 1.
