More specifically, the Union Park property is located north of the Front Range Village (FRV) commercial area, east of the Affinity residences, south of the English Ranch residential subdivision, and west of Ziegler Road. The project site is approximately 32.78 acres currently and is undeveloped agricultural and rural residential land, with one residence and multiple outbuildings. The site appears to be mostly vegetated with grass harvested for livestock feed. The site generally slopes from the west to the east at about 0.7% slope. The property is anticipated to be a high-density multi-use development, mainly multi-family residential, with retail space and supporting amenities according to the approved Ziegler- Corbett Overall Development Plan (ODP), the approved Preliminary Development Plan (PDP) and Harmony Corridor District/Plan per the City’s Land Use Code. The Union Park property is located within the City’s Fox Meadows Drainage Basin. In addition to the City of Fort Collins Stormwater Design Standards, drainage requirements are also described in both the “Final Drainage and Erosion Control Study for Front Range Village,” prepared by Stantec Consulting Inc., dated February 2007, and the “Final Drainage Report for Affinity Fort Collins,” prepared by JR Engineering, LLC, dated March 2, 2016. No City or FEMA floodplains/floodways are located within the Union Park property. SITE SOILS The Union Park project site consists primarily of Nunn clay loam (0 to 1 percent slopes) that is classified as Type-C hydrologic group. According to USDA/Natural Resource Conservation “Group, Type C soils have a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission.” 2 Per the “Preliminary Geotechnical Subsurface Exploration Report, Proposed Ziegler-Corbett Mixed-Use Development”, prepared by Soilogic, Inc., dated April 4, 2022: “approximately 4 to 6 inches of vegetation and topsoil was encountered at the surface at the boring locations, underlain by brown/beige/rust lean clay with varying amounts of sand which varied to clayey sand in places. The apparently-natural lean clay/clayey sand varied from soft to hard in terms of consistency or from very loose to medium dense in terms of relative density, typically exhibited no to low swell potential at in-situ moisture and density conditions (however one sample of sandy lean clay obtained from boring B-2 at a depth of about 9 feet below ground surface exhibited moderate swell potential) and extended to the bottom of each of the borings at a depth of approximately 15feet below present site grades.” “Groundwater was observed during the subsurface soil exploration: “Groundwater was not encountered in borings B-1, B-2, B-3 or B-5 to the depths explored (about 15 feet below ground surface), but was measured at a depth of about 15 feet below ground surface in boring B-4 when checked immediately after completion of drilling. When checked about five (5) days after drilling, borings B-1, B-2 and B-5 remained dry to the approximate depth explored, while groundwater was measured at a depth of about 14 feet below ground surface at the locations of borings B-3 and B-4 at that time. Groundwater information is indicated in the upper right- hand corner of the attached boring logs.” “Groundwater levels will vary seasonally and over time based on weather conditions, site development, irrigation practices and other hydrologic conditions. Perched and/or trapped groundwater conditions may also be encountered at times throughout the year. Perched water is commonly encountered in soils overlying less permeable soil layers and/or bedrock. Trapped water is typically encountered within more permeable zones of layered soil and bedrock systems. The location and amount of perched/trapped water can also vary over time.” SOIL TYPE PERCENT OF SITE HYDROLOGIC SOIL GROUP1 K FACTOR2 WIND GROUP3 1Hydrologic soil groups range from A to D with group A having a high infiltration rate and D having a very slow infiltration rate 2K factors range from 0.02 to 0.69. The higher value, the more susceptible the soil is to sheet and rill erosion by water. 3Soils assigned to wind group 1 are the most susceptible to wind erosion, soils assigned to wind group 8 are the least susceptible. 3 implement an adequate erosion control strategy to control sediment migration from leaving the site. Please refer to Appendix E for the detailed on-site soil information from the NRCS Soil Survey of Larimer County.

Detail drawings of these BMPs are also included in Appendix A. These BMPs are expected to change as the construction progresses and it is the responsibility of the contractor to ensure appropriate BMPs are in place and/or removed at the appropriate time in the construction sequence. All temporary and permanent erosion and sediment control practices must be maintained and repaired as needed to assure continued performance of their intended function. All BMPs shall be inspected and repaired or replaced as described further in this report and as required to satisfy the conditions of the Permit. Project is anticipated to be constructed in 5 phases, with Phase A representing the site overlot grading, and back bone infrastructure including the utilities, storm drain, detention ponds, and private drives. Importing and stockpiling the additional soil needed for the project and the overlot grading will occur in Phase A. Phase A will install the overall perimeter controls and the remaining Phases B, C, D, and E will install perimeter controls as it pertains to the limits of construction and individual construction entrances/vehicle tracking pads and concrete wash out areas. Refer to the included phasing plan for the limits of each construction phase. Phases may be combined sequentially as necessary. Refer to Erosion & Sedimentation Control Plans for detailed BMP sequencing and maintenance plans for the project through all stages of construction. Soil stockpiles should be kept below the locally mandated maximum height and surrounded with silt fencing or other acceptable means. If the storage of these soils is going to be for an extended period of time, then consider temporarily seeding the soil to minimize soil loss to wind and water erosion. Per the City of Fort Collins Stormwater Criteria Manual: 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 6 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. Vehicle tracking pads are intended to trap mud and sediment within coarse grain material and provide clean access to public roadways. Wherever construction vehicle access routes intersect paved public roads a vehicle tracking control pad shall be installed to minimize the transport of sediment (mud) by runoff or vehicles tracking onto the paved surface. Pads shall be maintained and refurbished when necessary to obtain their intended result. Concrete washout area is intended to contain washout liquids and solids that result from the cleaning of concrete trucks and pumps. Washouts should be placed near the area where the concrete is being poured and 50 ft from any stormwater or drainage course. Three below grade infiltration galleries are proposed for the site to meet Low Impact Development requirements for water quality treatment. These galleries are located in open space areas. Upstream protection will be necessary to protect the galleries from receiving significant amount of sediment during construction and prior to the contributing basins being well established with vegetation. It is recommended that post construction the infiltration galleries are inspected and any accumulated sediment be removed prior to transferring ownership to the homeowner association. Inlet protection, silt fencing, and rock socks prevent sediment from entering storm drainage systems prior to permanent stabilization of the disturbed site area via ponding and settling of sediment. Rock socks or gravel bags shall be placed at existing and proposed inlets on and near the site as inlet protection. Inlet protection must be inspected and maintained after every rainfall event that produces runoff. Sediment must be removed and rocks repaired/replaced. Silt fencing and rock socks will also be used as perimeter protection at the toe of slopes and landscaped areas. Silt fencing and rock socks shall be installed immediately upon completion of over-lot grading. NON-STRUCTURAL PRACTICES: All low sloped areas exposed during land disturbing activity (stripping, grading, utility installations, stockpiling, filling, etc.) shall be kept in a roughened condition by ripping or disking along land contours until mulch, vegetation or other permanent erosion control is installed. All steep sloped areas exposed during land disturbing activity (stripping, grading, utility installations, stockpiling, filling, etc.) shall have slope protection. The contractor shall use a "tracked" vehicle, run perpendicular to slope so that the tracking runs on the contour to inhibit rill/gully erosion; the contractor may use other windrow-type methods as necessary. 7 No soil shall remain exposed by land disturbing activity for more than thirty (30) days. At that time temporary or permanent erosion control seed/mulch, landscaping, etc. is required.

These items have been evaluated below for this project: 1. Disturbed and stored soil – YES – The construction will require that areas be disturbed exposing soil including foundation construction, paving and repaving, slope construction, and utility installation, and demolition required as shown on the plans. BMPs will include silt fence and sediment control logs and inlet protection on existing and proposed inlets, minimizing disturbance of existing vegetation and hard surfaces, and slope roughening and tracking of slopes after disturbance and prior to landscaping, paving, or building will be implemented. 2. Vehicle tracking of sediment – YES – The construction will require that subgrade be prepared for pavement and that vehicles drive on unpaved surfaces to the proposed buildings and utility improvement locations. BMPs will include a policy that vehicles be clean prior to entering the site and, if they become muddy during construction or earthwork activities, mud is removed by hand from the vehicle prior to departing the site in an area near the vehicle tracking pad. Any soil that is tracked from the site is to be disposed of in the trash dumpster by sweeping or scraping the material off the street. Any muddy vehicle will use the vehicle tracking pad prior to leaving the site. 3. Management of contaminated soil – NO – To our knowledge, there is not any existing soil contamination on-site. 4. Loading and unloading operations – YES – Chemicals and petroleum products will be brought to the site. Anytime these are being transported, they will be in a sealed container. 5. Outdoor storage activities – YES – Inert materials such as wood and stone will be stored outside and will likely be covered with tarps or plastic but are not pollutant sources and are not covered by the permit. Chemicals and petroleum products will be stored within the construction trailer or storage shed. Cement and mortar bags (if not contained in a vehicle or storage shed) will be completely covered with plastic to avoid contact with precipitation. 6. Vehicle and equipment maintenance and fueling – YES – Vehicle maintenance 11 and fueling, associated with construction of the proposed improvements, will take place. No fuel will be stored on site. 7. Significant dust or particulate generating processes – YES – Most of the site will be exposed from the over-lot grading of the project. In order to control the dust or particulate generating process a water truck or similar watering device will be available at all times. The disturbed ground will be watered as needed to control dust from leaving the site. The area of heavy construction is very limited and none of the operations are expected to generate significant dust. All dust control measures shall be completed in reference to the City’s Fugitive Dust Ordinance (Ordinance No. 044, 2016) and Dust Prevention and Control Manual. 8. Routine maintenance activities involving fertilizers, pesticides, detergents, fuels, solvents, oils, etc. – YES – Fertilizers and pesticides will not be used. Any cleaning or maintenance of small equipment will be required to be done within a containment device (horse trough or small “kiddy pool” and the liquid disposed of properly and legally. 9. On-site waste management – YES – The building and site construction will result in construction waste. A dumpster for trash and a dumpster for bulk recycling will be on the site. Waste will be hauled to the dumpsters by hand or in loaders. Dumpsters will be hauled off as needed. No construction waste will be left outside overnight without being located in a dumpster. No construction debris (including broken concrete) may be buried on the site. 10. Concrete truck/equipment washing – YES – A concrete washout will be provided on site. This will be used for trucks and for any masonry / concrete tools. 11. Dedicated asphalt of concrete batch plants – NO – None on this project. 12. Non-structural waste sources such as worker trash and portable toilets – YES – Trash dumpster will be available for worker’s trash and will be located near the construction trailer and emptied weekly. Portable toilets will be staked on site near the construction trailer. 13. Other areas where potential spills can occur – NO – The above 12 items are adequate for the anticipated construction process. THE CONTRACTOR IS TO UPDATE THE ABOVE INFORMATION WITH EXACT LOCATIONS OF THE CONSTRUCTION TRAILER, VEHICLE TRACKING PAD, CONCRETE WASHOUT, DUMPSTERS, AND PORTABLE TOILETS PRIOR TO COMMENCEMENT OF CONSTRUCTION AND UPDATE AS NECESSARY THROUGHOUT THE CONSTRUCTION SEQUENCE. 12 FINAL STABILIZATION AND LONG-TERM STORMWATER MANAGEMENT Final stabilization shall be considered achieved once all proposed site improvements are in place, all vegetation is established as identified on the landscape plan, all temporary BMPs are removed, and the downstream conveyances are inspected and certified to be clean and free from any construction debris resulting from the construction. Areas controlled by grass sod will be considered established upon the completion of the sod installation. Areas of seeding will be considered established at a vegetative density of 70%. Permanent Stormwater BMPs Grassed Swale with Permanent Turf Reinforcement Mat: A permanent grassed swale along the east of the site will treat basin B5.1 to reduce pollutant loading and runoff through infiltration. The swale is proposed to have Rollmax™ C350 Turf Reinforcement Mat (TRM) installed as a permanent BMP. The swale requires routine maintenance (mowing, turf maintenance, sediment and trash removal, etc.). The swale should be inspected at least twice yearly and immediately after major storm events for erosion, sediment build-up, vegetation health, etc. Permanent Riprap Outlet Protection: Permanent riprap protection has been proposed at the exit of all culvert pipes. The intent of the riprap aprons is to resist erosive forces from stormwater exiting the culverts. The riprap aprons require routine maintenance (sediment and trash removal, riprap required replacement etc.). The riprap aprons should be inspected at least twice yearly and immediately after major storm events for erosion, sediment build-up, rip-rap integrity, etc. 13 INSPECTION AND MAINTENANCE Site inspections will be performed to effectively address maintenance, repair, and adequacy of BMPs. The site inspections will be performed by the SWMP Administrator or his designee a minimum of once every fourteen (14) calendar days on active construction sites and within 24 hours after a significant storm event (event causing erosion). As part of the site inspections the inspector will keep documentation of all inspections and BMP maintenance, including updated Site Maps indicating new BMPs or the removal of BMPs since the previous inspection. Blank Site Maps will be utilized and will be redlined by the SWMP Administrator throughout construction to note all BMPs, pollutant sources, storage locations, etc. Any maintenance, repair, or necessary installation of BMPs that are noted during the inspection must begin immediately. The modifications shall be noted in the SWMP and the action taken as a result of the inspection shall be noted and certified on or attached to the original inspection report (date and time that the repair or change was started and finished and a certification that it was done properly). 14 SWMP IMPLEMENTATION It is the responsibility of the contractor to operate and maintain all facilities and systems of treatment and control which are installed to achieve compliance with the conditions of the permit. This includes effective performance, adequate funding, adequate staffing and training, etc. (see permit). All personnel on the construction site who will be in a position to affect or be affected by the SWMP shall be trained prior to beginning work. These individuals will be given general orientation information regarding the project and SWMP, shown where the SWMP is physically located, the SWMP will be explained to them and available for their review, and the enforcement policy will be reviewed. Throughout the construction, as a part of a weekly safety meeting, the SWMP will be reviewed with all attendees and any incidents discussed. All attendees shall be logged. 15 APPENDIX Appendix A – BMP Details Appendix B – Vicinity Map, Phasing Plan, and Drainage & Erosion Control Plans Appendix C – Construction Sequence Appendix D – Erosion Control Escrow Calculation Appendix E – Soil Information Appendix F – City of Fort Collins Standard Erosion Control Notes Appendix A APPENDIX A – BMP DETAILS RE V I S I O N NO .

Hydrologic Soil Group—Larimer County Area, Colorado (Union Park ) Natural Resources Conservation Service Web Soil Survey National Cooperative Soil Survey 4/10/2024 Page 2 of 4 Hydrologic Soil Group Map unit symbol Map unit name Rating Acres in AOI Percent of AOI 73 Nunn clay loam, 0 to 1 percent slopes C 31.1 93.2% 74 Nunn clay loam, 1 to 3 percent slopes C 2.3 6.8% Totals for Area of Interest 33.4 100.0% Description Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. "Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments. Factor K does not apply to organic horizons and is not reported for those layers.

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