General Requirements This Stormwater Management Plan (SWMP) has been prepared for Dillon Companies/King Soopers, Inc., the developer of the site, to fulfill the SWMP requirements of the State of Colorado. The SWMP identifies all potential pollution sources which may be expected to affect stormwater quality and the initial (construction phase) and final (after construction) erosion and sedimentation control requirements. It also specifies the use and maintenance of control measures, designed in accordance with sound engineering and hydrologic practices, to reduce pollutants and sediment in stormwater discharges associated with construction activity. The control measures are presented in detail in the text of this report and are shown on the Erosion and Sediment Control plans (Site Maps) included in the back of this report. This site must Galloway&Company, Inc. Page 5 of 41 implement the provisions of this SWMP as written and updated from commencement of construction activity until final stabilization is complete. Both the owner and operator must apply as permittees, except for instances where the duties of the owner and operator are managed by the owner. The permittee is responsible for updating the SWMP as construction activity on the site dictates and documenting any changes within this document. Additionally, this SWMP details control measures and processes for spill prevention control and countermeasures which shall be adhered to on site. IV. Site Description Project Location Midtown Gardens Marketplace (hereafter referred to as "the site" or "project site") will be located at the northwest corner of South College Avenue and West Drake Road. It is bounded on north by an existing commercial development; on the south by West Drake Road (including a Jiffy Lube to remain); on the east by College Avenue; and on the west by the MAX-BRT Bus Line. Spring Creek is located north of the site. More specifically, the site is located in the Southeast Quarter of Section 23, Township 7 North, Range 69 West in the City of Fort Collins, County of Larimer and State of Colorado. Legal Description A replat of Lots 1, 2, and 4 of K-Mart Plaza, and all of Lot 2 of the extension of K-Mart Plaza, situated in the Southeast 1/4 of Section 23, Township 7 North, Range 69 West, of the 6'h Principle Meridian, City of Fort Collins, County of Larimar, State of Colorado. Project Coordinate Location • Longitude 105°04'40"W • Latitude 40°33'14"N The Midtown Gardens Marketplace will be developed in one phase and is approximately 11.34 acres. The existing vacant Kmart building along with the vacant retail building at the northeast corner of the site will be removed. A new King Soopers Marketplace will replace the Kmart, while a new King Soopers fueling station will replace the vacant retail building. The existing parking lot will be reconstructed to accommodate the new structures. The lot containing the Loaf N' Jug will remain vacant for future development but is included in this report in its developed condition. Galloway&Company, Inc. Page 6 of 41 V.

Improvements will include cut/fill grading, underground utility mains and service extensions, internal roadway installation, building foundation and vertical construction, installation of detention/water quality facilities, and installation of associated landscaping, parking, drives, and site amenities. VI. Existing Conditions Soils The NRCS Web Soil Survey of Fort Collins, Colorado indicates site soils to be a mix of soil types and Hydrologic Soil Groups (HSGs)including: • Nunn Clay Loam, HSG 'C', 100% of total project area Galloway&Company, Inc. Page 7 of 41 According to the USDA NRCS Web Soil Survey, 'Nunn Clay loam, 0 to 1 percent slopes' covers the entire project site. This soil is associated with Hydrologic Soil Group (HSG) 'C'. HSG 'C' soils have a slow infiltration rate when thoroughly wet and 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. Refer to Appendix A for the soil survey information. Existing Vegetation The site is currently fully developed and consists of a currently vacant Kmart store, a small retail building at the northeast corner of the site, a small retail on the southeast corner of the site (to remain), and an existing Loaf N' Jug fueling station. Receiving Waters The site has been broken into three basins, each with their own set of sub-basins. A description of each basin and their characteristics can be found below. The intent of the drainage design is to have the runoff from the majority of the site collected and drain through a water quality and detention facility prior to entering the existing storm sewer system offsite. Pond A has been sized based on the City of Fort Collins LID requirements for the necessary portions of the site, which will be located at the downstream connection point to the existing storm drain system at the southeast corner of the site in College Ave. The released stormwater from the site will travel in the existing storm sewer system, and ultimately reach Spring Creek. Extent of Disturbance The total area of the site is 11.34 acres. Construction of this project will account for disturbed and impervious areas as shown in the table below and will be completed in one phase. The earthwork for this project will result in fill which will be imported to the site. Total Disturbed Area (ac) 12.12 ac Pre-Construction Impervious Area (ac) 7.29 ac Post-Construction Impervious Area(ac) 7.11 ac Total new Impervious Area (ac) 0 ac The adjusted cut and fill quantities are listed below. Cut Volume = 1,710 CY Fill Volume = 10,250 CY Net Volume = 8,540 CY Fill Galloway&Company, Inc. Page 8 of 41 Sequence of Maior Activities The projected sequence of work is expected to occur in the following order, with some overlap and adjustments as site conditions dictate: • Install control measures • Demolish existing buildings and parking lot • Rough overlot grading • Grade building pad • Trench and install underground utilities • Commerce vertical construction • Fine grade the remainder of the site • Pavement installation • Seed native areas and install permanent landscaping • Remove final control measures upon establishment of vegetation Construction is anticipated to begin in June 2021 and substantial completion of the project is anticipated in July 2022. The major milestones of construction and their associated control measures are listed in the following table.

Page 9 of 41 Potential Pollution Sources During construction there is potential for pollution from grading, utility, roadway, and building construction activities. These activities include ground disturbance, refueling and maintenance of equipment, washing of equipment, concrete waste, and the on-site use of paints, solvents, and other chemicals required for construction. Additionally, there is potential for pollution from the concrete washout area, temporary batch plant, worker's trash and portable toilets. Locations of potential pollution sources will be shown and updated on the Site Maps by the ECA. The ECA is also responsible for adhering to the Spill Prevention and Control Plan included in Appendix E of this plan. Non-Stormwater Discharges Based on current information, the only non-stormwater discharge(s) anticipated are landscape irrigation return flow, emergency firefighting activities, discharge to the ground of concrete washout water, and construction dewatering activities. If landscape irrigation is to be installed, then potential return flow from the irrigation system must be documented. Emergency firefighting activities that may occur on the site are permissible under the Colorado General Permit for Stormwater Discharges Associated with Construction Activity. A designated contained concrete washout area is located on the Site Map; infiltration discharge of concrete washout water from washing of tools and concrete mixer chutes may be discharged on this construction site provided that control measures in accordance with Part 1.B.1.a.ii.(b) of the Colorado General Permit for Stormwater Discharges Associated with Construction Activity are installed to prevent pollution of groundwater and discharges do not leave the site as surface runoff or to surface waters. If low risk discharges including potable water monitoring devices, potable water snowmelt, or uncontaminated groundwater to land occur, they must be discharged in accordance with the CDPHE Low Risk Discharge policies. VII. Stormwater Management Controls Erosion Control Administrator The Erosion Control Administrator (ECA) is an individual knowledgeable in the principles and practices of erosion and sediment control and pollution prevention and has the skills to assess conditions at construction sites that could impact stormwater quality and to assess the effectiveness of stormwater controls implemented to meet the requirements of the CDPS General Permit. The Permittee(s) is responsible for ensuring that the inspector is a qualified stormwater manager. The Permittee(s) shall Galloway&Company, Inc. Page 10 of 41 designate a ECA who will be the contact for all SWMP related issues and the person responsible for its accuracy, completeness, and implementation. The ECA should be a person with authority to adequately manage and direct day-to-day stormwater quality management activities at the site. The ECA is responsible for holding a weekly stormwater meeting attended by the Permittee(s) with all contractors and subcontractors involved in ground-disturbing activities to review the requirements of the Permit(s), the SWMP, and address any problems that have arisen in implementing the SWMP or maintaining the BMPs. The ECA shall maintain a log of all weekly meetings and document the issues addressed in the meetings. The name and contact information for the Erosion Control Administrator is: Name: TBD Phone: TBD Potential Pollutant Sources Potential pollutant sources for this site include: Disturbed and Stored Soils — Areas on the project site that are to be disturbed will be grubbed and overlot graded prior to major utility and roadway construction. This will be a one-time activity, per construction phase, and should be completed relatively early in the project timeline. The areas of grading that will not require additional disturbance shall receive final landscaping within 7 days. Otherwise temporary seeding and mulching will be required within 7 days of last disturbance if no further disturbance is anticipated for at least 14 days. Any soil stockpiles utilized during construction will be covered with a tarpaulin when not in active use and will have silt fence installed along the base of the slope. Construction Vehicle Entrance and Vehicle Tracking of Sediments —There is potential for tracking of soils between the beginning of the grading process and the final stabilization of the site. Construction vehicle entrances shall be minimized to reduce the potential for tracking of soils off-site and vehicle tracking control shall be installed at each construction entrance. Vehicle tracking control is to be installed prior to land disturbance activities and sweeping is to take place as needed. Vehicle access to the exposed and disturbed subgrade will be limited primarily to roll on/off earthmoving equipment and heavy materials delivery trucks. The ECA is responsible for ensuring that access to exposed subgrade is limited, both in quantity and in timing relative to the tracking susceptibility of the soil as it relates to moisture content. The ECA must keep the adjacent parking areas and public rights-of-way free from mud and other tracked debris from the site. Galloway&Company, Inc. Page 11 of 41 Management of Contaminated Soils — Contaminated soils are not anticipated based on due diligence conducted for the project site. If suspect soils are encountered construction activity shall immediately halt and environmental professionals shall review the materials and provide recommendations on handling of materials. All handling of materials shall be in accordance with State and Federal regulations. Loading and Unloading Operations—Loading and unloading operations are expected during demolition and during the delivery and staging of materials and equipment. Additionally, imported materials may be necessary to achieve final grades. All loading and unloading operations of equipment shall be accomplished in areas protected by erosion and sediment controls. It is recommended that all equipment be cleaned on-site and within protected areas prior to exiting the site. Outdoor Storage Activities — Outdoor storage is anticipated during construction activities including delivery and staging of materials. Potential chemicals include paint, fuel, oil, form oil, hydraulic fluid, plumbing glue, and fertilizer. Outdoor storage activities shall be limited to the designated stabilized staging area. All stored chemicals require protection from the elements and must be stored off the ground in some manner. An emergency spill kit is required to be in proximity of any stored chemicals and hazardous materials. The kit at a minimum would have a broom, chemical absorbent, shovel, and turn pallets. Good housekeeping practices shall be employed to prevent pollution associated with solid, liquid, and hazardous construction-related materials and wastes. Secondary containment for fuel tanks, petroleum products, and chemicals shall be utilized to reduce the likelihood of contamination of State Waters and Waters of the United States. The ECA shall show storage locations on the site maps and update them as needed. Fueling of Vehicles and Equipment — Vehicle and equipment fueling shall occur within the stabilized staging area. Fueling is expected to occur during all phases of construction activity. Under no circumstances shall fueling take place within 200 feet of any State Waters or Waters of the United States or within 50 feet of an inlet or ditch. Spill response kits shall be readily available an accessible at locations where fueling takes place. Please refer to the Hazardous Material Management and Spill Reporting Plan section for information on clean-up and disposal of spills. Temporary on-site fuel tanks for construction vehicles shall meet all state and federal regulations. Tanks shall have approved spill containment with the capacity required by the applicable regulations. From NFPA 30: All tanks shall be provided with secondary containment (i.e. containment external to and separate from primary containment). Secondary containment shall be constructed of materials of sufficient thickness, density, and composition so as not to be structurally weakened as a result of contact with the fuel stored and capable of containing discharged fuel for a period of time equal to or longer than the maximum anticipated time sufficient to allow recovery of discharged fuel. It shall be capable of Galloway&Company, Inc. Page 12 of 41 containing 110% of the volume of the primary tank if a single tank is used, or in the case of multiple tanks, 150% of the largest tank or 10% of the aggregate, whichever is larger. The tanks shall be in sound condition free of rust or other damage which might compromise containment. Fuel storage areas will meet all EPA, OSHA and other regulatory requirements for signage, fire extinguisher, etc. Hoses, valves, fittings, caps, filler nozzles, and associated hardware shall be maintained in proper working condition at all times. The location of fuel tanks shall be shown on the Site Maps and shall be located to minimize exposure to weather and surface water drainage features. A Spill Prevention and Control (SPCP) Plan has been included in Appendix E. Maintenance of Vehicles and Equipment— If equipment is to be maintained and stored in an open area this area should not be within the drip line of trees and not be within 100 feet of a watercourse or wetland. Runoff should be diverted away from watercourses and wetlands. Maintenance should be done on impervious areas surrounded with impervious berms. Where this is not possible, use pads designed to contain the pollutants which may leak or spill during maintenance operations. Impervious pads are particularly important on sandy and other course soils where spilled materials can easily leach into the groundwater. Equipment shall be checked before and after each use and, minimally, during the weekly stormwater inspection if otherwise idle. Periodic checks of the equipment wash areas shall be performed to ensure proper operation. Hazardous Material Management and Spill Reporting Plan —Any hazardous or potentially hazardous material that is brought onto the construction site will be handled properly in order to reduce the potential for storm water pollution. All materials used on this construction site will be properly stored including the use of secondary containment measures, handled, dispensed and disposed of following all applicable label directions. Flammable and combustible liquids will be stored and handled according to 29 CFR 1926.152. Only approved containers and portable tanks shall be used for storage and handling of flammable and combustible liquids. Material Safety Data Sheets (MSDS) information will be kept on site for any and all applicable materials. In the event of an accidental spill, immediate action will be undertaken by the General Contractor to contain and remove the spilled material. All hazardous materials will be disposed of by the Contractor in the manner specified by federal, state and local regulations and by the manufacturer of such products. As soon as possible, the spill will be reported to the appropriate agencies. As required under the provisions of the Clean Water Act, any spill or discharge entering waters of the United States will be properly reported. The General Contractor will prepare a written record of all spills and associated clean- Galloway&Company, Inc. Page 13 of 41 up and also notify the City of Fort Collins at 970-221-6700. Spills should be reported online at Access Fort Collins (https://clients.comcate.com/newrequest.php?id=150). The General Contractor will provide notice to Owner immediately upon identification of a reportable spill. Any spills of petroleum products or hazardous materials in excess of Reportable Quantities as defined by EPA or the state or local agency regulations, shall be immediately reported to the EPA National Response Center (1-800-424-8802), the Colorado Department of Public Health and Environment (CDPHE) (1-877-518-5608), the City of Fort Collins at(970-221-6700). The State reportable quantity for petroleum products is 25 gallons or more (or that cause a sheen on nearby surface waters). Spills from regulated aboveground and underground fuel storage tanks must be reported to the State Oil Inspector within 24 hours (after-hours contact CDPHE Emergency Spill Reporting Line). This includes spills from fuel pumps. Spills or releases of hazardous substances from regulated storage tanks in excess of the reportable quantity (40 CFR Part 302.6) must be reported to the National Response Center, the local fire authority immediately, the State Oil Inspector, and the City of Fort Collins within 24 hours. The reportable quantity for hazardous materials can be found in 40 CFR 302 at: http://www.ecfr.gov/cqi-bin/text-idx?tpl=/ecfrbrowse/Title40/40cfr302 main 02.tpl In order to minimize the potential for a spill of petroleum product or hazardous materials to come in contact with storm water, the following steps will be implemented: a) All materials with hazardous properties (such as pesticides, petroleum products, fertilizers, detergents, construction chemicals, acids, paints, paint solvents, additives for soil stabilization, concrete, curing compounds and additives, etc.) will be stored including secondary containment measures in a secure location, under cover, when not in use. b) The minimum practical quantity of all such materials will be kept on the job site and scheduled for delivery as close to time of use as practical. c) A spill control and containment kit (containing for example, absorbent material such as kitty litter or sawdust, acid neutralizing agent, brooms, dust pans, mops, rags, gloves, goggles, plastic and metal trash containers, etc.) will be provided on the construction site and location(s) shown on Site Maps. The kit should be inspected for completeness as a part of weekly stormwater inspections. d) All of the product in a container will be used before the container is disposed of. All such containers will be triple rinsed with water prior to disposal. The rinse water used in these containers will be disposed of in a manner in compliance with state and federal regulations and will not be allowed to mix with storm water discharges. Galloway&Company, Inc. Page 14 of 41 e) All products will be stored in and used from the original container with the original product label. f) All products will be used in strict compliance with instructions on the product label. g) The disposal of excess or used products will be in strict compliance with instructions on the products label and local regulations. The contractor is responsible for the Spill Prevention and Control Plan (SPCP) included in Appendix D of the SWMP. If the contractor elects to provide his own SPCP it must be included in Appendix D as a replacement. A contractor provided SPCP shall clearly state measures to stop the source of a spill, contain the spill, clean up the spill, dispose of contaminated materials, and train personnel to prevent and control future spills. In addition, the SPCP must include contact and documentation requirements for each of the Minor, Significant, and Hazardous spill magnitudes. Further requirements are listed below in the equipment fueling section. Significant Dust or Particulate Generating Processes — Dust and airborne particulates can be expected during clearing and grubbing, site grading, saw cutting, and final stabilization activities. Dust mitigation shall be implemented as necessary. Routine Maintenance Activities Involving Chemicals, Detergents, Fuels, Solvents, Oils, etc. — On- site routine maintenance activities involving fertilizers, pesticides, detergents, fuels, solvents, oils, etc. shall occur within the stabilized staging area when possible and shall be kept to a minimum. Routine maintenance activities are expected to occur during all phases of construction activity. The ECA shall show storage locations on the appropriate plan sheets and update them as needed. All chemicals are to be protected from the elements. Spill response kits shall be readily available an accessible at locations where maintenance takes place. Please refer to the Hazardous Material Management and Spill Reporting Plan section for information on clean-up and disposal of spills. On-Site Waste Management — Waste generation is expected as a result of construction activities. All waste shall be properly stored and disposed of to minimize the potential for pollution of stormwater or snowmelt runoff. Additionally, on-site waste should be stored such that wind will not transport refuse away from the storage area. This may include the use of storage containers, dumpsters, fencing or covers. Concrete Truck/Equipment Washing (including truck chute and associated fixtures and equipment) — Concrete washout area shall be installed prior to any concrete placement on site. Signs shall be placed at the construction entrance(s), at the washout area, and elsewhere as necessary to clearly indicate the location of the concrete washout area. The washout area shall be repaired and Galloway&Company, Inc. Page 15 of 41 enlarged or cleaned out as necessary to maintain capacity for wasted concrete. Concrete and concrete wash water shall be removed from the site and disposed of at an accepted waste facility. Dedicated Asphalt and Concrete Batch Plants — A small temporary batch plant may be installed to allow on-site storage and mixing of concrete and masonry. This should be protected by sediment traps, silt fence, diversion ditches or other perimeter protection as appropriate to keep stockpiled material within the plant area and located on the Site Maps by the ECA. Non-Industrial Waste Management Worker's Trash — The site shall be policed at the end of each work day to be kept free of trash and debris resulting from workers day to day activities. If necessary, utilize clearly marked and protected containers for trash and debris at convenient locations throughout the site. Burying of waste on site is prohibited. Trash must be properly contained at the end of each day. Portable Toilets — All personnel involved with construction activities must comply with state and local sanitary or septic system regulations. Temporary sanitary facilities will be provided at the site throughout the construction phase. They must be utilized by all construction personnel and must be serviced weekly by a commercial operator. The location of sanitary facilities shall be shown on the Site Maps. Portable toilets must be securely anchored a minimum of 10' behind curbs and are not allowed within 50' of inlets or within 50' of a water of the State or the municipal storm drain system. Concrete and Saw Cutting Waste — Concrete and asphalt cutting are expected during demolition activities. The waste material from these operations will be fully contained and cleaned up immediately by vacuum. Any remaining residue shall be cleaned by vacuum or street sweeping. Dewatering — Dewatering of excavations shall occur as permitted by a Water Quality Control Division Low Risk Guidance Document. Any water from dewatering operations shall be uncontaminated and discharge to a control measure and captured on-site for infiltration and/or evaporation. Under no circumstances shall construction dewatering water be allowed to leave the site as surface runoff. If contamination of groundwater is suspected, a separate construction dewatering permit will be required. Control Measures for Stormwater Pollution Prevention The following erosion control, sediment control, materials management, and site management measures shall be utilized and/or installed as indicated on the site maps to reduce the potential of the sources identified above to contribute pollutants to stormwater discharges. Galloway&Company, Inc. Page 16 of 41 The following structural control measures are anticipated to be implemented on this site: BMP Quantity Unit Permanent Seeding 0.93 AC Wind Erosion and Dust Control 12.12 AC Concrete Washout Area 1 EA Silt Fence 3123 LF Rock Sock 12 LF Storm Sewer Inlet Protection 16 EA Construction Fence 2614 LF Vehicle Tracking Control 1 SY Stabilized Staging Area 1636 SY Site maps and control details can be found in Appendix B of this document. Erosion Control Temporary and Permanent Seeding —All denuded areas that will be inactive for 14 days or more must be stabilized temporarily with the use of fast-germinating annual grass/grain varieties appropriate for site soil and climate conditions, straw/hay mulch, wood cellulose fibers, tackifiers, netting and/or blankets. Stockpiles and diversion ditches/berms must be stabilized to prevent erosion and dust issues. A City of Fort Collins approved seed mix shall be used. All areas at final grade must be seeded or sodded within 14 days after completion of work in that area. Prepare soil and seed immediately after final grade is achieved. At the completion of ground-disturbing activities the entire site must have permanent vegetative cover, meeting vegetative density requirements, or mulch per landscape plan, in all areas not covered by hardscape (pavement, buildings, etc.). Except for small (<100 SF) level spots, seeded areas should be protected with mulch, tackifier, or a rolled erosion control product. Mulch must be crimped by disc or other machinery. Wind Erosion and Dust Control — Wind erosion and dust control measures help to keep soil particles from entering the air because of land disturbing construction activities. These control measures include a variety of practices generally focused on either graded disturbed areas or construction roadways. For graded areas, practices such as seeding and mulching, use of soil binders, site watering, or other practices that provide prompt surface cover should be used. For construction roadways, road watering and stabilized surfaces should be considered. Dust control measures should be used on any site where dust poses a problem to air quality. Dust control is important to control for the health of construction workers and surrounding waterbodies. Dust control shall be implemented throughout construction once the site has any exposed, bare soil. It shall be implemented until all bare soil has been covered by final stabilization. Galloway&Company, Inc. Page 17 of 41 Materials Management Concrete Washout Area —The concrete washout area shall be installed prior to any concrete placement on site. Signs shall be placed at the construction entrance(s), at the washout area, and elsewhere as necessary to clearly indicate the location of the concrete washout area. The washout area shall be repaired and enlarged or cleaned out as necessary to maintain capacity for wasted concrete. Concrete shall be removed from the site and disposed of at an accepted waste facility. The concrete washout area shall be installed as shown on site maps prior to any concrete work. It shall remain in place until all concrete work is complete. Stockpile Management — Stockpile management includes measures to minimize erosion and sediment transport from soil stockpiles. Soil stockpiles shall be located away from all drainage system components including inlets. When practical, choose stockpile locations that will remain undisturbed for the longest period of time as the phases of construction progress. Place sediment control measures such as silt fence, straw wattles, or rock socks around the perimeter of all stockpiles. For stockpiles in active use, provide a stabilized designated access point on the upgradient side of the stockpile. Soils stockpiled for more than 60 days should be seeded and mulched with a temporary grass cover. Soil stockpile management shall be installed when soil stockpiling begins. It shall remain in place until all soil has been replaced or hauled off-site to a permanent location. Good Housekeeping Practices — A clean and orderly work site reduces the possibility of accidental spills and reduces safety hazards to employees and subcontractors. It will also help minimize potential contamination of stormwater runoff. Housekeeping practices are to include providing waste management, establishing proper building material staging areas, designating paint and concrete washout areas, establishing proper equipment and vehicle fueling and maintenance practices, controlling equipment and vehicle washing and allowable non-stormwater discharges, and developing a spill prevention and response plan. Good housekeeping practices shall be employed throughout the duration of construction. Sediment Control Silt Fence — Silt fence is a synthetic permeable woven or non-woven geotextile fabric incorporating support stakes at intervals sufficient to support the fence (5-feet maximum distance between posts), water, and sediment retained by the fence. The fence is designed to retain sediment-laden storm water and allow settlement of suspended soils before the storm water flows through the fabric and discharges off-site. Silt fence shall be located on the contour to capture overland, low-velocity sheet flows. Silt fence shall be installed at the start of construction prior to any earth moving activities. Silt fence shall remain in Galloway&Company, Inc. Page 18 of 41 place until site construction has been completed to a point where other control measures can control the remaining sediment concerns. Rock Sock — Rock socks consist of gravel wrapped by wire mesh or a geotextile to form an elongated cylindrical filter to prevent sediment transfer. They are used to trap sediment from stormwater runoff that flows onto roadways as a result of construction activities. They can be used as curb flow control, perimeter control, or as part of inlet protection. Rock socks shall be installed at the start of construction prior to any earth moving activities. Rock socks shall remain in place until final stabilization. Storm Sewer Inlet Protection — Inlet protection devices intercept and/or filter sediment before it can be transported from a site into the storm drain system and discharged into a lake, river, stream, wetland, or other body of water. These devices also keep sediment from filling or clogging storm drain pipes, ditches, and downgradient sediment traps or ponds. Inlet protection may also include placement of a barrier to create a bypass of an inlet transferring flow downstream to a sediment trap, basin, or other inlet discharging to a non-critical area. The primary mechanism is to place controls in the path of flow sufficient to slow the sediment-laden water to allow settlement of suspended soils before discharging into the storm sewer. It is possible that as construction progresses from storm sewer installation through to paving that the inlet protection devices should change. All inlet protection devices create ponding of storm water. This should be taken into consideration when deciding on which device or devices should be used. Inlet protection shall be installed around all existing inlets at the start of construction prior to any earth moving activities and around all proposed inlets as they are constructed. Inlet protection shall remain in place until final stabilization (pavement and/or landscaping). Site Management and Other Practices Construction Phasing and Scheduling — Effective construction site management to minimize erosion and sediment transport includes attention to construction phasing, scheduling, and sequencing of land disturbing activities. On most construction projects, erosion and sediment controls will need to be adjusted as the project progresses and should be documented in the SWMP. All construction projects can benefit from upfront planning to phase and sequence construction activities to minimize the extent and duration of disturbance. Larger projects and linear construction projects may benefit most from construction sequencing or phasing, but even small projects can benefit from construction sequencing that minimizes the duration of disturbance. Typically, erosion and sediment controls needed at a site will change as a site progresses through the major phases of construction. Erosion and sediment control practices corresponding to each phase of construction must be documented in the SWMP. Protection of Existing Vegetation — Existing vegetation should be preserved for the maximum practical duration on a construction site through the use of effective construction phasing. Preserving vegetation Galloway&Company, Inc. Page 19 of 41 helps to minimize erosion and can reduce revegetation costs following construction. Potential sources of injury to existing trees include soil compaction during grading or due to construction traffic, direct equipment-related injury such as bark removal, branch breakage, surface grading and trenching, and soil cut and fill. In order to minimize injuries that may lead to immediate or later death of the tree, tree protection zones shall be established at the beginning of a construction project and remain in place until final stabilization. Construction Fence— Construction fence shall restrict site access to designated entrances and exits for safety and preservation of adjacent areas. Construction fence shall be installed around the perimeter of the site except at construction access points at the start of construction prior to any earth moving activities. It shall remain in place until construction is complete and no further threat to public safety exists (e.g. open trenches, heavy operating equipment on-site). Vehicle Tracking Control — Vehicles leaving construction sites can track sediment onto adjoining roadways. This sediment can create safety hazards and contribute significantly to sediment pollution in waterways. The purpose of a vehicle tracking control measure is to prevent soil and mud on work vehicles from being carried offsite and deposited on public roads, parking lots, and other areas. All points closed to the general public and providing access into the construction site shall include a marked construction exit that will be monitored for any signs of tracking from the construction site. It is expected that only trailer delivered equipment will access the exposed subgrades and that vehicle tracking to the adjacent publicly accessible parking and the public rights-of-way should not be evident. However, if that proves not to be the case a roughened exit composed of ribbed steel plate and down-gradient silt dikes is to be installed to the dimensions shown on the site maps. The rough texture of the plates helps to remove clumps of soil adhering to the construction vehicle tires through the action of vibration and jarring over the rough surface and the friction of the ribbed matrix against soils attached to vehicle tires. It may also be necessary to install a wheel wash system. If this is done, a sediment trap control must be installed to treat the wash water before it discharges from the site. Discharge must be directed to the sediment basin within the limits of construction as indicated. The vehicle tracking control shall be installed at all construction access points at the start of construction prior to any earth moving activities. It shall remain in place until permanent pavement is installed. Stabilized Construction Roadway—A stabilized construction roadway is a temporary method to control sediment runoff, vehicle tracking, and dust from roads during construction activities. When a construction roadway is expected to have frequent construction traffic it is advisable to install a stabilized construction roadway instead of rough-cut street controls. The road surface shall be stabilized with an aggregate base course of 3-inch diameter granular material. Roadside ditches shall also be stabilized if applicable. Early application of road base is typically suitable in place of the coarse aggregate specified above. Galloway&Company, Inc. Page 20 of 41 Stabilized Staging Area—This is a clearly designated area where construction equipment and vehicles, stockpiles, waste bins, and other construction-related materials are stored. The stabilized storage area consists of a stabilized surface, covered with 3-inch diameter aggregate or larger. The stabilized staging area shall be installed as shown on the site maps at the start of construction prior to any earth moving activities. It shall remain in place until permanent pavement is installed. Street Sweeping and Vacuuming — Street sweeping and vacuuming remove sediment that has been tracked onto roadways to reduce sediment transport into storm drain systems or a surface waterway. Street sweeping or vacuuming should be conducted when there is noticeable sediment accumulation on roadways on or adjacent to the construction site. Typically, this will be concentrated at the entrance/exit to the construction site. Well-maintained stabilized construction entrances, vehicle tracking controls and tire wash facilities can help reduce the necessary frequency of street sweeping and vacuuming. Street sweeping shall occur as needed and at a minimum once a day throughout the duration of construction. Dewatering Operations — Dewatering typically involves pumping water from an inundated area to a control measure, and then downstream to a receiving waterway, sediment basin, or well-vegetated area. Dewatering typically involves several control measures in sequence. Dewatering operations are used when an area of the construction site needs to be dewatered as the result of a large storm event, groundwater, or existing ponding conditions. This can occur during deep excavation, utility trenching, and wetland or pond excavation. All dewatering discharges must be treated to remove sediment before discharging from the construction site. Discharging water into a sediment trap or basin is an acceptable treatment option. Water may also be treated using a dewatering filter bag and a series of straw bales or sediment logs. If these options are not feasible, a settling tank or an active treatment system may need to be utilized. Settling tanks are manufactured tanks with a series of baffles to promote settling. Flocculants can also be added to the tank to induce more rapid settling. Contact the state agency for special requirements prior to using flocculants and land application techniques. Some commonly used methods to handle the pumped water without surface discharge include land application to vegetated areas through a perforated discharge hose (i.e., the "sprinkler method") or dispersal from a water truck for dust control. Paving and Grinding Operations — Runoff from paving and grinding operations shall be managed to minimize pollutants entering storm drainage systems and natural waterways. Use runoff management practices during all paving and grinding operations such as surfacing, resurfacing, and saw cutting. Revising Control Measures and the SWMP Should there be changes to the implemented control measures the ECA shall be notified and the SWMP modified to accurately reflect the field conditions. Examples include, but are not limited to, removal of Galloway&Company, Inc. Page 21 of 41 control measures, identification of new potential pollutant sources, addition of control measures, modification of control measure installation and implementation criteria or maintenance procedures, and changes in items included in the Site Map and/or description. SWMP revisions must be made prior to changes in site conditions, except for Responsive SWMP Changes, as follows: • SWMP revisions must be made immediately after changes are made in the field to address control measure installation and/or implementation issues; or • SWMP revisions that require the development of supporting documentation (e.g. design of sediment basin capacity) must be made as soon as practicable, but in no case more than 72 hours, after change(s) in control measure installation and/or implementation occur at the site. Notation must be included in the plan that identifies: • The date of the site change • The control measure removed or modified • The location(s) of those control measure(s) • Any changes to the control measure(s) Demolition & Permitting Prior to construction and building permit, the demolition permit must be obtained. Once the demo permit is acquired, construction on the site may begin. Demolition of the site will include the destruction of an existing commercial building, removal of an existing parking lot, and removal of existing topsoil. During this phase, erosion control measures must also be in place to mitigate affects due to dust and other forms of off-site impacts. Erosion control measures used in this phase must be in place prior to demolition and may include the following: dust control and watering, construction fences, silt fences, inlet protection, rock socks, concrete washouts, and vehicle tracking control. This SWMP should be viewed as a "living document'that is to be continuously reviewed and modified as part of the overall process of assessing and managing stormwater quality issues on-site. Vill. Final Stabilization & Long-Term Stormwater Management Permanent stabilization of the site will include establishment of native seeded areas in specified ROW and overlot graded areas with a City of Fort Collins approved seed mix, permanent landscaping areas, and pavement placement. In accordance with the CDPS General Permit for Stormwater Discharges Associated with Construction Activity (COR-400000) (the stormwater permit): "Final site stabilization is achieved when perennial vegetative cover provides permanent stabilization with a density greater than 70 percent of pre-disturbance levels over the entire area to be stabilized by vegetative cover or equivalent Galloway&Company, Inc. Page 22 of 41 cover has been employed." Additionally, all permanent stormwater control measures must be completed and operational as designed and any stormwater conveyances cleaned of sediment and stabilized. Further, all temporary stormwater control measures must be removed unless designed to decompose on- site. The following criteria must be met when planning for final stabilization: • Stabilization must be permanent • ALL disturbed areas must be stabilized • Alternatives must follow good practice The stormwater permit allows the use of alternatives to vegetation to achieve final stabilization. These alternatives must meet specific criteria to be considered equivalent to vegetation. Examples of alternative stabilization practices include: • Permanent Paving and Buildings • Hardscape • Geogrid • Xeriscape • Compacted and Stabilized Unpaved Driving Surfaces This site will be constructed in one phase. The only area that will receive permanent seeding is the future pad lot at the southeast corner of the site. Refer to the Seed Mix below and notes on the Final Landscape Plans.

Page 23 of 41 Inactivation of Permit Coverage Once the criteria for final stabilization have been met, the Permittee shall make a request to terminate the permit through the Colorado Environmental Online Services (CEOS) system. The ECA shall provide a completed SWMP binder to the owner at the conclusion of the project which will include the original SWMP, all markups or other changes to the SWMP, and inspection and maintenance records. The owner shall keep this document on file for a minimum of 3 years after construction completion. IX. Inspection & Maintenance Procedures The contractor must keep the approved SWMP on site at all times. The person(s) inspecting the site may be on the Permittee's staff or a third party hired to conduct stormwater inspections under the direction of the Permittee. The Permittee is responsible for ensuring that the inspector is a qualified stormwater manager. All regulatory authorities may inspect the land or site covered by the SWMP at any time, without prior notice, for compliance with the SWMP. If site conditions indicate that the objectives of this section are not being met, the operator shall make appropriate modifications to the SWMP. Any modification must be recorded on the owner's copy of the SWMP and the ECA notified. The Permittee must maintain inspection records on site with the SWMP and such records must be provided to the regulatory agencies for review upon request. At a minimum, the inspection report must include: • The inspection date • Name(s) and title(s)of personnel conducting the inspection • Weather conditions at the time of inspection • Phase of construction at the time of inspection • Estimated acreage of disturbance at the time of inspection • Location(s)of discharges of sediment or other pollutants from the site • Location(s)of control measures needing maintenance • Location(s)and identification of inadequate control measures • Location(s) and identification of additional control measures needed that were not in place at the time of inspection. • Description of the minimum inspection frequency (either in accordance with Part I.D.2., I.D.3. or I.D.4.) utilized when conducting each inspection. • Deviations from the minimum inspection schedule as required in Part I.D.2. • After adequate corrective action(s)and maintenance have been taken, or where a report does not identify incidents requiring corrective action or maintenance, the report shall contain a statement as required in Part I.A.3.f. Galloway&Company, Inc. Page 24 of 41 The State Construction Stormwater Site Inspection Report template has been included in Appendix D. The Permittee may provide their own inspection report if desired but must ensure it meets the requirements above. Inspection Schedules Between the time this SWMP is implemented and final Inactivation Notice or Termination Application has been submitted, all disturbed areas and pollutant controls must be inspected with one of the following minimum frequencies: • At least one inspection every 7 calendar days • At least one inspection every 14 calendar days, plus post-storm event inspections conducted within 24 hours after the end of any precipitation or snowmelt event that causes surface erosion. If more frequent inspections are required to ensure that control measures are properly maintained and operated, the inspection schedule must be modified to meet this need. The first site inspection must occur within 7 calendar days of the commencement of construction activities on site. The contractor and ECA shall adhere to the maintenance schedules listed in the details for each control measure. Permittees must conduct site inspections at least once every 7 calendar days for sites that discharge to a water body designated as an Outstanding Water by the Water Quality Control Commission. Preventative maintenance shall be coupled with periodic inspections. Inspection Procedures The purpose of site inspections is to assess performance of pollutant controls. Based on these inspections the contractor, in consultation with the ECA (if different) will decide whether it is necessary to modify this SWMP, add or relocate controls, or revise or implement additional control measures in order to prevent pollutants from leaving the site via stormwater runoff. The contractor has the duty to cause pollutant control measures to be repaired, modified, supplemented, or take additional steps as necessary in order to achieve effective pollutant control. Note: If a control measure is covered by snow, mark the control measure as not applicable and document the reason the control measure cannot be inspected on the daily report. The inspection must include observation of: • The construction site perimeter and discharge points, including discharges into a storm sewer system • All disturbed areas • Areas used for material/waste storage that are exposed to precipitation • Areas determined to have a significant potential for stormwater pollution, such as demolition areas, concrete washout areas, or construction vehicle entrances • All erosion and sediment control measures identified in the SWMP Galloway&Company, Inc. Page 25 of 41 • Structural control measures that may require maintenance, such as secondary containment around fuel tanks or the condition of spill response kits Examples of specific items to evaluate during site inspections are listed below. This list is not intended to be comprehensive. During each inspection, the inspector must evaluate overall pollutant control system performance as well as particular details of individual system components. Additional factors should be considered as appropriate to the circumstances. Additional information on maintenance requirements can be found in the BMP Fact Sheets in Volume 3 of the Urban Storm Drainage Criteria Manual by the Urban Drainage and Flood Control District. Construction Exit and Track Out— Locations where vehicles enter and exit the site must be inspected for evidence of off-site sediment tracking. A stabilized construction exit shall be constructed where vehicles enter and exit. Exits shall be maintained or supplemented as necessary to prevent the release of sediment from vehicles leaving the site. Any sediment deposited on the roadway shall be swept as necessary throughout the day or at the end of every day and disposed of in an appropriate manner. Sediment shall NOT be washed into storm sewer systems. Erosion Control Devices— Rolled erosion control products (nets, blankets, turf reinforcement mats) and marginally vegetated areas (areas not meeting required vegetative densities for final stabilization) must be inspected weekly. Rilling, rutting and other signs of erosion indicate the erosion control device is not functioning properly and additional erosion control devices are warranted. Material Storage Areas — Material storage areas should be located to minimize exposure to weather. Inspections shall evaluate disturbed areas and areas used for storing materials that are exposed to rainfall for evidence of, or the potential for, pollutants entering the drainage system or discharging from the site. If necessary, the materials must be covered or original covers must be repaired or supplemented. Also, protective berms must be constructed, if needed, in order to contain runoff from material storage areas. All state and local regulations pertaining to material storage areas will be adhered to. Discharge Points — All discharge points must be inspected to determine whether erosion and sediment control measures are effective in preventing discharge of sediment from the site or impacts to receiving waters. Control Measure Maintenance/Replacement and Failed Control Measures The Colorado General Permit for Stormwater Discharges Associated with Construction Activity requires that all erosion and sediment control practices and other protective measures identified in the SWMP be maintained in effective operating condition and in accordance with good engineering, hydrologic and Galloway&Company, Inc. Page 26 of 41 pollution control practices. Sediment that has been collected by sediment controls, such as silt fence and inlet protection, shall be removed when observed to prevent failure of control measures, and remove the potential of that sediment from being discharged from the site if the control measure did fail. Removed sediment shall be properly disposed of on-site. Maintenance activities to correct problems noted during inspections must be documented as discussed in the documentation section below. The inspection process must also include procedures to ensure that, when needed, control measures are replaced or new control measures added to adequately manage the pollutant sources at the site. This procedure is part of the ongoing process of revising the control measures and the SWMP as discussed above, and any changes to control measures must be recorded in the SWMP. The SWMP must be modified as soon as practicable to reflect current conditions. Control measures that have failed or have the potential to fail without maintenance or modifications must be addressed as soon as possible, immediately in most cases, to prevent the discharge of pollutants. If it is infeasible to install or repair a control measure immediately after discovering the deficiency, the following information must be documented and kept on record: 1) Describe why it is infeasible to initiate the installation or repair immediately; and 2) Provide a schedule for installing or repairing the control measure and returning it to an effective operating condition as soon as possible. If applicable, the Permittee must remove and properly dispose of any unauthorized release or discharge (e.g. discharge of non-stormwater, spill or leak not authorized by the Construction Stormwater Permit). The Permittee must also clean up any contaminated surfaces to minimize discharges of the material in subsequent storm events. Record Keeping and Documentation All erosion control measures and stabilizations shall be inspected weekly and after each precipitation or snow melt event. The Permittee must document inspection results and maintain a record of the results for a period of 3 years following closing of permit coverage. These records must be made available to the Owner, the City & County, the State, or the EPA upon request. The following items must be documented as part of the site inspections: • The inspection date • Name(s) and title(s)of personnel making the inspection • Location(s)of discharges of sediment or other pollutants from the site • Location(s)of control measures that need to be maintained • Location(s) of control measures that failed to operate as designed or proved inadequate for a particular location • Location(s) where additional control measures are needed that were not in place at the time of inspection • Deviations from the minimum inspection schedule as indicated above Galloway&Company, Inc. Page 27 of 41 • Description and dates of corrective actions taken including requisite changes to the SWMP After adequate corrective action(s) has been taken, or where a report does not identify any incidents requiring corrective action, the report shall contain a signed statement indicating the site is in compliance with the permit to the best of the signer's knowledge and belief. Record of spills, leaks, or overflows that result in the discharge of pollutants must be documented and maintained. Information that should be recorded for all occurrences includes the time and date, weather conditions, reasons for the spill, who the spill was reported to, etc. A complete copy of the SWMP shall be kept with the inspection and maintenance records for the aforementioned 3-year period. X. Standard City of Fort Collins Erosion Control Notes 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, Galloway&Company, Inc. Page 28 of 41 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 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. Galloway&Company, Inc. Page 29 of 41 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 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. 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. Galloway&Company, Inc. Page 30 of 41 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 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 Galloway&Company, Inc. Page 31 of 41 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.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/ portal/nres/main/soils/health/)and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 5 Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and 6 Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, 11 Custom Soil Resource Report onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform.An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Larimer County Area, Colorado 73—Nunn clay loam, 0 to 1 percent slopes Map Unit Setting National map unit symbol: 2ting Elevation: 4,100 to 5,700 feet Mean annual precipitation: 14 to 15 inches Mean annual air temperature: 48 to 52 degrees F Frost-free period: 135 to 152 days Farmland classification: Prime farmland if irrigated Map Unit Composition Nunn and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

Introduction The following Spill Prevention and Response Plan shall be implemented during the construction of improvements at Midtown Gardens Marketplace — King Soopers # 146, and associated thereto. This plan will be implemented to meet the requirements of the City of Fort Collins and the State of Colorado. Materials On-Site Spill control procedures will be implemented when materials are stockpiled or when chemicals and/or fluids are used in the construction area. Stockpiles of Dry Materials The following spill prevention procedures shall be implemented: All materials shall be stockpiled in designated areas,with control measures used to reduce and minimize the runoff of contaminants. Control measures such as silt fence and sediment control logs will be installed according to City of Fort Collins criteria using the details shown on the SWMP plans. Loading and unloading operations shall be performed in a manner to limit materials from being spilled.Any spilled materials shall be swept up immediately after the operations are performed. Vehicle Fueling The following spill prevention procedures shall be implemented: All vehicle fueling will be done off-site as much as possible. All on-site fueling operations will be performed in designated areas. Measures will be taken where necessary to reduce and minimize spills during vehicle fueling operations. These measures may include the placement of a temporary berm around the fueling area, covering the fueling area under a temporary portable structure, and/or the placement of drip pans under valves and tank openings. Berms will be constructed around all fueling areas. An adequate supply of absorbents will also be stockpiled at each fueling area. Routine Vehicle and Equipment Maintenance The following spill prevention procedures shall be implemented: All vehicle maintenance will be performed off-site when possible. However, there may be occasions where construction equipment and vehicles may break down at the site and on-site repairs are more feasible. On-site vehicle and equipment maintenance, if needed, will be performed in designated areas, where practical, and enclosed by earthen berms.All maintenance areas will maintain an adequate supply of drip pans. These pans will be placed underneath vehicles as needed and absorbents will be used in the event of a minor spill or leak. SPILL RESPONSE Galloway&Company, Inc. Page 1 of 5 NOTE: IN CASE OF FIRE, EVACUATE ALL PERSONNEL FROM THE IMMEDIATE AREA, RENDER FIRST AID TO ANYONE WHO IS INJURED, AND DIAL 911 IMMEDIATELY. TAKE APPROPRIATE STEPS TO PROTECT HUMAN LIFE AND TO CONTROL FIRES FIRST. SPILL CONTROL IS A SECONDARY CONCERN. Cleanup and Removal Procedures • 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 supervisor 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 employee will attend to the source or begin cleanup of the spill until ALL emergency priorities (fire, injuries, etc.) have been addressed. 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 shall 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 of the liquid as possible and to prevent or minimize infiltration into the soil. 4. Once the liquids have been absorbed, remove all absorbents from the spill and place the materials in a suitable storage 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 the soil 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 thickness 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 contaminants 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, including the following: •Type of pollutant • Location •Apparent source • Estimated volume • Time of discovery • Actions taken to clean up spill Galloway&Company, Inc. Page 2 of 5 7. Notify the supervisor of the spill and provide the information from Item #6. The supervisor will then contact the City of Fort Collins and Larimer County. 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. 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 supervisor 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 supervisor 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. Any 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 a 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 10. Provide the supervisor (or designated employee) with the information from Item #9. The supervisor will then contact the City of Fort Collins and Larimer County. Galloway&Company, Inc.
