College Avenue and W. Trilby Road, more specifically, Lot 2, C.O.L. College and Trilby Subdivision, situated in the Southeast Quarter of Section 11, Township 6 North, Range 69 West of the 6 th P.M., City of Fort Collins, County of Larimer, State of Colorado. Latitude, 40⁰ 29’ 45.50” N – Longitude, 105⁰ 04’ 40.56” W Existing Site Description The site is bounded by Southgate Church to the south, undeveloped fields to the west and north, and S. College Avenue to the east. The existing site consists of a detention pond, paved parking and drive areas, a naturally vegetated area, and an improved landscaped area. Generally, the naturally vegetated area and the paved parking and drive areas drain to the detention pond either directly or via an onsite storm sewer system, while, the improved landscaped area sheet flows directly to S. College Avenue. Soils Data / Groundwater According to the Preliminary Geotechnical Engineering Report prepared March 5, 2003 by Terracon, the site consists of sandy lean clay fill material, which correlates to soil Type ‘C’. Type ‘C’ soils have low infiltration rates when thoroughly wetted. Anticipate moderate erosion potential from this soil. The report also states that groundwater was encountered at eighteen feet below the existing site grade. Based on these findings, dewatering is not anticipated to be required for the project. Nature of Construction Activities The proposed Ziggi’s Coffee development is 1.63 Acres and will consist of demolition activities, building construction, approximately 492 square feet, concrete installation (drive-thru lane, curb and gutter, sidewalk, patio, and bike rack area, and trash enclosure pad), ADA parking, and utility service installation. Final Stabilization of the site will be achieved through permanent landscaping, pavement and building areas. The following is a breakdown of the project area and raw earthwork volumes: • Site area – 1.630 AC • Area disturbed – 0.484 AC • Export Import Volume – 59 C.Y. Cut and 97 C.Y. Fill HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900 Page 4 of 18 Existing Vegetation Existing ground cover in the proposed improvement areas generally consists of pavement and improved landscaped areas. The correlating existing percent impervious is 68.1%. The middle third section of Lot 2, originally planned for future building construction, is covered in natural vegetation and exhibits approximately 70% vegetative ground cover. Receiving Waters Runoff from the site is generally collected by an existing onsite storm sewer system and conveyed north to the onsite detention pond. Runoff from the improved landscaped area along the eastern boundary releases offsite undetained, directly to S. College Avenue. This undetained runoff joins the detained runoff in an existing inlet near the northeast corner the site. Runoff is then conveyed east by a combination of storm sewer and open channels to Fossil Creek, approximately 1.35 miles east of the site. STORMWATER MANAGEMENT CONTROLS Potential Sources of Pollution The following are potential sources of pollution for this site. 1. All disturbed and stored soils: The total area disturbed is 0.484 acres. Stockpiling is not anticipated to be needed for the project based on earthwork volumes. The total area of disturbed soils exposed at one time shall be kept to a minimum and shall be temporarily seeded if exposed for more than 30 days. Sediment control logs shall be placed around site boundaries where runoff escapes offsite. Inlet protection and curb socks shall be installed at existing downstream storm inlets. 2. Vehicle tracking of sediments: Site access is limited to one location. Vehicle Tracking Control (VTC) shall be installed once existing pavement is demolished in order to connect the paved drive lane to the Stabilized Staging Area (SSA). Street sweeping shall be performed daily. Vehicle traffic shall only enter disturbed areas based on required construction activities. 3. Management of contaminated soils: To the best of our knowledge there are no existing onsite contaminated soils. Contaminated soils from demolition or pavement activities shall be contained and properly disposed of. Contractor shall follow the “Spill Response Plan” section of this report, should a spill occur onsite. HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900 Page 5 of 18 4. Loading and unloading operations: Vehicle traffic shall only enter disturbed areas based on required construction activities. Loading and unloading operations shall be confined to the Stabilized Staging Area (SSA) to the extent construction activities will allow. 5. Outdoor storage activities (building materials, fertilizers, chemicals, etc.): Outdoor storage activities shall be confined to the SSA. Hazardous materials shall be locked up and stored in spill proof containers. Contractor shall follow the “Spill Response Plan” section of this report, should a spill occur onsite. 6. Vehicle and equipment maintenance and fueling: Vehicle and equipment maintenance and fueling shall only occur in the SSA, unless taken off site. Contractor shall follow the “Spill Response Plan” section of this report, should a spill occur onsite. 7. Significant dust or particle generating processes: The total area of disturbed soils exposed at one time shall be kept to a minimum and shall be temporarily seeded if exposed for more than 30 days. If disturbed soils begin to generate significant amounts of dust, site watering shall be used. On May 3, 2016, the City of Fort Collins passed Ordinance No. 044, 2016 (Fugitive Dust Ordinance), which amended Chapter 12 of the Code of the City of Fort Collins. Further information on the new requirements and Best Management Practices (BMPs) can be referenced in the City of Fort Collins Dust Prevention and Control Manual. 8. Routine maintenance activities involving fertilizers, pesticides, detergents, fuels, solvents, oils, etc.: Routine maintenance activities shall be confined to the SSA to the extent construction activities allow. Contractor shall follow the “Spill Response Plan” section of this report, should a spill occur onsite. 9. Onsite waste management practices (waste piles, liquid wastes, dumpsters, etc.): Waste sources shall be confined to the SSA and must be located a minimum of 50 feet from any inlet structures or watercourses. Contractor shall determine how demolition material is to be disposed of as the project progress. 10. Concrete truck/equipment washing, including the concrete truck chute and associated fixtures and equipment: Concrete Washout Area (CWA) shall be accessible from the SSA and must be located a minimum of 50 feet from any inlet structures or watercourses. No untreated water from concrete activities is permitted to the leave site. Site boundaries near CWA shall be protected with sediment control logs. 11. Dedicated asphalt and concrete batch plants: Dedicated asphalt and concrete batch plants are not anticipated to be required for the project. HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900 Page 6 of 18 12. Non-industrial waste sources such as worker trash and portable toilets: Non-industrial waste sources shall be confined to the SSA and must be located a minimum of 50 feet from any inlet structures or watercourses. Non-industrial waste shall be removed from the site on a regular basis and as demand dictates. 13. Other areas or procedures where potential spills can occur: Dewatering is not anticipated to be required for the project.

RENDER FIRST AID TO ANYONE WHO IS INJURED, AND DIAL 911 IMMEDIATELY. TAKE APPROPRIATE STEPS TO PROTECT HUMAN LIFE AND TO CONTROL FIRE FIRST. SPILL IS SECONDARY. Upon detection of any spill, the first action to be taken is to ensure personal safety. All possible ignition sources, including running engines, electrical equipment (including cellular telephones, etc.), or other hazards will be immediately turned off or removed from the area. The extent of the spill and the nature of the spilled material will be evaluated to determine if remedial actions could result in any health hazards, escalation of the spill, or further damage that would intensify the problem. If such conditions exist, a designated employee will oversee the area of the spill and the construction SWMP administrator will be notified immediately. The source of the spill will be identified and if possible the flow of pollutants stopped if it can be done safely. However, no one should attend to the source or begin cleanup of the spill until ALL emergency priorities (fire, injuries, etc.) have been addressed. HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900 Page 11 of 18 Small Spills Small spills (usually < 5 gallons) consist of minor quantities of gasoline, oil, anti-freeze, or other materials that can be cleaned up by a single employee using readily available materials. The following procedures should be used for clean-up of small spills: 1. Ensure personal safety, evaluate the spill, and if possible stop the flow of pollutants. 2. Contain the spread of the spill using absorbents, portable berms, sandbags or other available measures. 3. Spread absorbent materials on the area to soak up as much liquid as possible and to prevent infiltration into the soil. 4. Once liquids have been absorbed, remove all absorbents from the spill and place the materials in a suitable container. On paved areas, wipe any remaining liquids from the surface and place the materials in a storage container. Do not spray or wash down the area using water. For open soil areas, excavate any contaminated soil as soon as possible and place in a suitable storage container. All materials will then be transported off-site for disposal. 5. If immediate transfer and storage of the contaminated soil is not practical, excavate and place the contaminated soil on a double sheet of 3-mil or higher polyethylene film. In addition, a small berm should be formed around the outer edges of the soil stockpile, underneath the polyethylene film, to ensure that contaminates are not washed from the site during precipitation events and that materials do not seep through the berm. 6. Record all significant facts and information about the spill, include the following: • Type of pollutant • Location • Apparent source • Estimated volume • Time of discovery • Actions taken to clean up spill 7. Notify the SWMP Administrator of the spill and provide the information from item #6. The SWMP Administrator will then contact City of Fort Collins. Medium to Large Spills Medium to large spills consist of larger quantities of materials (usually >5 – 25 gallons) that are used on site that cannot be controlled by a single employee. Generally, a number of facility personnel will be needed to control the spill and a response may require the suspension of other facility activities. HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900 Page 12 of 18 The following procedure shall be used for the cleanup of medium to large spills: 1. Ensure personal safety, evaluate the spill, and if possible, stop the flow of pollutants. 2. Immediately dispatch a front-end loader or similar equipment to the spill and construct a berm or berms down gradient of the spill to minimize the spread of potential pollutants. On paved surfaces, portable berms, sandbags, booms, or other measures will be used to control the lateral spread of the pollutants. 3. When the spread of the spill has been laterally contained, contact the SWMP Administrator or designated facility employee and provide them information on the location, type, and amount of spilled material, and a briefing on the extent of the spread and measures undertaken to contain the contaminants. 4. Depending on the nature of the spill, mobilize additional resources as needed to contain the contaminants. 5. Cleanup will commence when the lateral spread has been contained and the notification to the SWMP Administrator has been made. 6. Freestanding liquid will be bailed or pumped into 55-gallon storage drums, steel tanks, or other suitable storage containers. When all the liquid has been removed from the pavement or soil layer, absorbents will be applied to the surface and transferred to the storage containers when they have soaked up as much of the spill as possible. 7. On paved surfaces, the remaining contaminants will be removed to the extent possible, with rags, sweeping, or similar measures. The area of the spill will not be sprayed or washed down using water. And contaminant soaked materials will be placed into the storage containers with the other absorbents. 8. The remaining contaminated soils will be excavated and loaded into a dump truck(s) for disposal off-site at designated facility. If transport off-site is not immediately available, the remaining soils will be stockpiled on a double thickness sheet of 3-mil or higher polyethylene film. In addition, a small berm will be formed around the outer edges of the soil stockpile, underneath the polyethylene film, to ensure that contaminants are not washed from the site during precipitation and do not seep through the berm. 9. Record all significant facts and information about the spill, including the following: • Type of pollutant • Location • Apparent source • Estimated volume • Time of discovery actions taken to clean up spill HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900 Page 13 of 18 10. Provide the SWMP Administrator (or designated employee) with the information from Item #9. The SWMP Administrator will then contact the City of Fort Collins.
