Site Description Roaring Fork Ranch is located at 16704 U.S. Highway 82, which is located approximately between Carbondale and El Jebel, within unincorporated Garfield County. The site is situatcd within Section 32, Township 7 South, Range 87, West ofthe 6th Principal Meridian. A Vicinity Map has been included in Appendix A. Proposed construction activities within the site are to include; site grading and installation of irrigation culverts. II. Construction Sectuence Implementation of this Stormwater Management Plan will begin at the start of construction and be maintained as needed until final stabilization is achieved. The anticipated start of construction is anticipated to begin during the autumn of 2017. Construction will consist of multiple phases: 1. Clearing and grubbing the site to remove organics should commence during the autumn 2017. 2. Grading of the proposed landscape berms and installation of irrigation culverts should commence in during the autumn 2017 and work in progress for 10 years based on market demand until 2027 3. Landscaping will be completed as market demand allows for completion of the berms. The site should be stabilized by 2027. III. Proposed Area of Disturbance The overall area of the property is approximately 69.5 acres. The estimated total area of the site to be disturbed by clearing, excavation, grading and other construction activities is 8.4 acres. A Site Map has been included in Appendix D. IV. Description of Soils According to the "Soil Survey of Aspen -Gypsum Area, Colorado" published by the United States Department of Agriculture Soil Conservation Service in cooperation with the Colorado Agricultural Experiment Station, the soil type within the site is Atencio—Azeltine complex. This hydrologic group B soil is described as deep and well drained. The soil is formed in alluvium derived dominantly from sandstone and shale. Permeability is moderate, and water capacity is low. Runoff is slow and the hazard of erosion is slight. Page 3 V. Description of Existing Vegetation The site is currently developed with buildings and equestrian facilities. The majority of the property currently consists of native grasses, shrubs and trees. The estimated percentage of existing ground vegetation coverage of the site is approximately 60 -percent. VI. Potential Sources of Pollution Potential pollution sources during construction include equipment refueling and maintenance, grading operations. VII. Allowable Non -Storm 'Vater Discharges No non -storm water discharges are proposed. VIII. Receiving, Waters The immediate receiving water of storm water runoff from for the site is the Roaring Fork River, which is situated approximately 1,000 feet south of the site. The Roaring Fork River continues for approximately 16 -miles, to the northwest eventually discharging into the Colorado River at Glenwood Springs. The storm water management sequence will include the installation of Best Management Practices (BMP' s), including silt control fence as perimeter sediment control, straw erosion logs, and straw bale check dams, or other BMP's within drainage ways as necessary. Once the initial BMP's are in place site grading will begin. Stabilization ofthe soil will begin after each construction activity is completed, as reasonably as possible, including seeding, landscaping, and necessary erosion control measures. The stabilization methods are further discussed below. IV. Best Management Practices (BMWs) The following describes the site management practices that will be implemented on the construction site. These BMP's will be used are located in Appendix B as necessary to minimize erosion and sediment discharge. Details of commonly installed BMP's • During clearing and grubbing, excavation and grading construction activities silt control fences will be installed parallel to the toe of banks and at the low side of all cuts. Check dams (staked straw bales and straw logs) will be placed in the flow line ofthe drainage paths, as necessary. • During rough grading erosion control blankets or vegetation will be placed on slopes of 2:1 or greater as shown on the grading plan. Page 4 • Final re -vegetation and landscaping commence and all necessary seeding for final re-veg will be installed and BMP's will be maintained until permanent vegetation has taken hold. It is anticipated that these BMP's will be sufficient to minimize sediment discharge into the river, however additional BMP's may be used if necessary. Appendix B includes details of the commonly used BMP's mentioned above. Sediment and mud shall be prevented from leaving the construction site by installing a vehicle tracking pad. The contractor is responsible for cleaning and general upkeep of existing roads used for access. Major soil disturbances will be seeded and mulched within seven (7) days after final grade is reached or if areas have been exposed and inactive for more than forty five (45) days. In the interim condition, water trucks should be utilized onsite for the duration of the construction period to minimize fugitive dust. Good housekeeping BMPs should be followed throughout the entire life of the project. These include the following: • Refuse receptacles should he regularly emptied and equipped with lids, • Keeping machinery in good operating condition to prevent leakage, and • Apply appropriate (not excessive) amounts of fertilizer to the landscaping • Scheduled maintenance of BMPs according to the State of Colorado Rules and Regulations Other housekeeping practices should include general site cleanliness and proper training of employees. X. Material Handling and Spill Prevention In the event that chemicals, fuels or other materials are stored on site the materials should be stored and handled in covered areas to prevent contact with stormwater, and chemicals should be stored within berms or secondary containment devices to prevent leaks and spills from entering stormwater runof. Cleaning and fueling of machinery should be done during dry weather, if possible. Washing of trucks and other equipment into the irrigation ditches is prohibited. Spills or accidents�ehlibepmme� immediately CnloradotDepart� De epartment of Health, P Administrator and depending on the nature ospill Garfield County, and other agencies may need to be notified. Page 5 XI. Final Stabilization Once grading activities are completed, final stabilization of the disturbed areas will occur in accordance with applicable Federal, State and County standards. When the site is determined to have reached the final stabilization stage, straw bales and other perimeter sedimentation control fences can be removed. XII. Inspection and Maintenance A thorough inspection and maintenance of the storm water management system is required every 14 days and after any precipitation or snowmelt event that causes surface runoff. The permit will describe the inspection procedures to follow. As part of the inspection, a logbook must be kept. The following information should be included in the logbook. • Records of any spills, leaks, or overflows, including time, date and weather condition, • Implementation of specific items in SWMP, • Events involving materials handling and storage, • Contacts with regulatory agencies • Maintenance and repair of storm water management controls, • Preventive maintenance activities, • Inspection activities and • Dated photographs. XIII. Retention of Records The permitee shall retain a copy of the Storm Water Management Plan required by this permit at the construction site from the date of project initiation to the date of final stabilization. The permitee shall retain copies of the Storm Water Management Plan and all reports required by the permit and records of all data used to complete this application for a period of at least three years from the date of final stabilization.

This means that all ground surface disturbing activities at the site have been completed, and all disturbed areas have been either built on, paved, or a uniform vegetative cover has been established with an individual plant density of at least 70 percent of pre -disturbance levels. Permit coverage must be maintained until the site is finally stabilized. Even if you are only doing one part of the project, the estimated final stabilization date must be for the overall project. If permit coverage is still required once your part is completed, the permit certification may be transferred or reassigned to a new responsible entity(s).

Receiving waters are any waters of the State of Colorado. This includes all water courses, even if they are usually dry. If stormwater from the construction site enters a ditch or storm sewer system, identify that system and indicate the ultimate receiving water for the ditch or storm sewer.
