SWPPP Page 4 of 13 HR Green, Inc. FIGURE I - PROJECT LOCATION MAP Chick-fil-A Chanhassen, MN Chick-fil-A, Inc. SWPPP Page 5 of 13 HR Green, Inc. A. Purpose Chick-fil-A Chanhassen, MN Chick-fil-A, Inc. The project will consist of the demolition of an existing building, parking lot, and utilities and the construction of a Chick-fil-A restaurant, parking lot, stormwater sewer system, underground stormwater management facilities, and associated utilities. This SWPPP will include the following: • Define the characteristics of the site and the type of construction that will occur. • Describe the site plan. • Describe the practices that will be implemented to control erosion and the release of pollutants in storm water. • Create an implementation schedule. • Describe the final stabilization design to minimize erosion and prevent storm water impacts after construction is complete. B. Project Size Construction limits for the proposed improvements and associated stormwater BMP construction is estimated to be approximately 1.36 acres. C. Impervious Surfaces Note: The Chick-fil-A improvements will disturb area outside of the proposed lease limits. Re -grading of the existing vegetated swale south of the property is proposed. a. EXISTING CONDITIONS The existing onsite impervious area is estimated to be 0.87 acres consisting of the building and associated parking lot. The impervious areas account for approximately 66% of the project area. b. PROPOSED CONDITIONS The project will result in an increase of impervious area from the existing condition. The proposed onsite impervious area is estimated to be 1.02 acres which is an increase of 11 percent. The site's stonnwater management system has been designed to limit peak runoff rates at or below existing rates. D. Construction Type The project includes demolition of the existing commercial building & parking lot and the construction of the Chick-fil-A restaurant, parking lot, storm sewer system, underground stonnwater management facilities, and other associated utilities. E. Receiving Water Body In the existing condition, the site currently sheet flows to an existing 15 -inch flared end section that is tributary to the Minnesota DOT storm sewer system. The site has been designed to detain runoff and release stormwater at a controlled rate to the DOT system, matching existing drainage patterns. The DOT stormwater system then flows south across STH No. 5. SWPPP Page 6 of 13 HR Green, Inc. F. Special or Impaired Waters on the Project Site Chick-fil-A Chanhassen, MN Chick-fil-A, Inc. There are no impaired waters within the project limits. The impaired waters discovered within one mile of the site include Lake Susan and Lake Lotus. The proposed Chick-fil-A project will have no effect on these existing impairments. G. NRCS Soil Types / Runoff Coefficients The Soil Conservation Service (SCS) Soil Survey designates the majority of the soils in the area as Le Sueur loam, Kilkenny -Lester loams, Cordova clay loam, and a smaller portion of Glencoe clay loam. The SCS soil map is attached in Appendix E. The proposed runoff coefficient for the site is 94. H. Project Features Project features are shown on the Construction Drawings. I. Dewatering If the project requires dewatering the Contractor shall be responsible for obtaining a Water Appropriation Permit from the Department of Natural Resources (DNR). The Contractor will also be responsible for obtaining all other necessary permits and approvals, as well as all fees and documentation associated with the permits. J. Dates of Construction Summer 2016 to Winter 2017 K. Sequencing The activities that will reduce erosion and sedimentation and the general order they are to be completed, is as follows: 1. Install temporary rock construction entrance. The stabilized construction site entrance shall be constructed prior to the start of construction. 2. Install inlet protection at locations as shown on the plans. Inlet protection shall be installed before any clearing and grading begins. 3. Clearing and grading will not occur in an area until it is necessary for construction to proceed. 4. Existing pavement and curb will be removed where specified in the plan. 5. Construct proposed storm sewer system and underground stormwater management system. 6. Erect building and construct parking lot. 7. Grade all grass areas to final grades and contours as shown in plan. 8. Install seed, mulch, and erosion control mat. 9. Remove temporary erosion control materials once construction has ceased. SWPPP Page 7 of 13 HR Green, Inc. L. General Information / Regulatory Requirements a. RATE CONTROL Chick-fil-A Chanhassen, MN Chick-fil-A, Inc. Rate control will be achieved through the underground stormwater management system and associated restrictor structure. The Chick-fil-A development will be required to limit peak runoff at or below existing conditions for the 2 -year, 10 -year-, 100 -year, and 100 -year 10 -day snow melt storm events. Although the Chick-fil-A development is increasing the impervious loading, stormwater discharge rates in the proposed condition will be lower than existing rates. b. WATER QUALITY The Chick-fil-A site will required to treat stormwater runoff to remove 60% total phosphorus and 90% total suspended solids. The site has been designed to incorporate an underground stormwater management system that will promote filtration through the open graded aggregate layer and infiltration into the native soils. This site will utilize a vegetated swale at the south side of the property as well. The site controls have been modeled in WinSLAMM v10.0 to ensure that the required stormwater treatment has been met. [ IOIDIMII;alvIm0l The Chick-fil-A site is required to provide a stormwater abstraction volume of 1.1 inches of runoff over all onsite impervious surfaces. This abstraction volume will be directed to the underground stormwater management system where it will be forced to infiltrate down through the native soils. Since the site is primarily made up of clayey soils with an infiltration rate of 0.06 inches per hour, the infiltration system has been designed with an approximate 17,100 square foot bed size to ensure the volume has a draw down time less than 48 hours. M. Identification of Potential Storm Water Contaminants The purpose of this section is to identify pollutants that could impact storm water during the parking lot and building construction. The possible pollutants that could be present in the storm water are listed in the following table. SWPPP Page 8 of 13 HR Green, Inc.

N. Potential Areas for Storm Water Contamination Chick-fil-A Chanhassen, MN Chick-fil-A, Inc. The following potential areas were identified as possible storm water contamination areas: • Cleared and graded areas • Roadway construction areas • Construction site entrances O. Stormwater Control Best Management Practices a. TEMPORARY • Inlet filter baskets will be installed under the storm sewer grates. • Silt Fence will be installed around the perimeter of the project limits. b. PERMANENT • Permanent stormwater treatment will be provided via infiltration through the proposed on-site underground stormwater management system. P. Erosion Prevention Best Management Practices a. TEMPORARY • Inlet Protection will be placed at the existing storm structures identified in the Plans, by the Contractor prior to beginning grading at locations in which runoff could move offsite. • Stabilized construction entrances will be constructed to help reduce vehicle tracking of sediments. The paved street adjacent to the site entrance will be swept daily to remove any excess mud, dirt or rock tracked from the site with a pickup broom. • Erosion control blanket will be utilized to stabilize soil on steep slopes and at apron outlets where applicable. • Vegetation in areas not needed for construction shall be preserved. • All exposed soil areas must be stabilized as soon as possible to limit soil erosion but in no case later than 14 days after the construction activity in that portion of the site has temporarily or permanently ceased. Temporary stockpiles without significant silt, clay or organic components (e.g., clean aggregate stockpiles, demolition concrete stockpiles, sand stockpiles) and the constructed base components of roads, parking lots and similar surfaces are exempt from this requirement but must comply with Part IV.C.5 of NPDES permit. • The normal wetted perimeter of any temporary or permanent drainage ditch or swale that drains water from any portion of the construction site, or diverts water around the site, must be stabilized within 200 lineal feet from the property edge, or from the point of discharge into any surface water. Stabilization of the last 200 lineal feet must be completed within 24 hours after connecting to a surface water. • Temporary seed shall be Mn/DOT Seed Mix Type 150 or 190. Application rate of temporary seed shall be 40 lbs/acre. Fertilizer shall be 24-12-24 (NPK) commercial grade analysis, applied at a rate of 300 lb/acre. • All storm sewer inlets shall be protected during construction using catch basin inlet barriers. Sediment shall be removed after each rainfall. • Construction sequencing will allow areas to be undisturbed until necessary for construction. SWPPP Page 10 of 13 HR Green, Inc. Chick-fil-A Chanhassen, MN Chick-fil-A, Inc. • Temporary and permanent seeding and/or planting areas will be inspected for bare spots and washouts. • A weekly written erosion control schedule will be required. It will discuss, among other items listed in the Construction Specification, how related work to offsite drainage will be incorporated into the weekly erosion plan schedule, how the SWPPP is functioning and any necessary changes that need to be discussed. • A maintenance inspection report will be completed by the Contractor and submitted to the Engineer for each inspection. b. PERMANENT • Permanent seeding and mulching and sod. • The smallest vegetated area possible will be disturbed during construction. Q. Sediment Control Best Management Practices a. TEMPORARY • Silt fence • Dewatering related to the construction activity that may have turbid or sediment laden discharge water must be discharged to a temporary sedimentation basin on the project site whenever possible. If dewatering discharges cannot be directed toward an existing silt fence, hay bale structure, or ditch check area, filter bags should be used to contain and filter sediment from the dewatering discharge. • All erosion control measures shall be inspected at least once per week and within 24 hours of all storm events greater than 0.5 inches. All measures will be maintained in good working order. • Built up sediment shall be removed from inlet protection within 24 hours when it has reached 1/2 the height of the device. R. General Best Management Practices • All non -hazardous waste materials will be collected and stored in a secure dumpster or another approved containrnent method at the end of each day. • Partially used bags of fertilizer will be transferred to a sealable bin to prevent spills. • All vehicles left onsite will be monitored for leaks to reduce the chance of contamination. • Petroleum products will be stored in tightly sealed, properly labeled containers. An effort will be made to store only enough product required to complete the job. • Products will be kept in their original containers with the original manufacturer's label. Manufacturers' recommendations for proper use and disposal will be followed. • Materials and equipment necessary for spill cleanup will be kept in the temporary material storage trailer onsite. • All spills will be cleaned up immediately upon discovery. Spills large enough to reach the storm conveyance system will be reported to the DNR Emergency Response & Homeland Security Unit (Environmental Hazardous Conditions) 515-281-8694. • Concrete trucks shall wash out or discharge surplus concrete or water in the designated wash out area on site. SWPPP Page 11 of 13 HR Green, Inc. Chick-fil-A Chanhassen, MN Chick-fil-A, Inc. • The Contractor shall comply with applicable State and local waste disposal, sanitary sewer, or septic system regulations. In the event of a conflict with other government laws, rules and regulations, the more restrictive laws, rules or regulations shall govern. • If construction activities or design modifications are made to the site plan that could impact storm water, this SWPPP will be amended appropriately. The amended SWPPP will have a description of the new activities that contribute to the increased pollutant loading and the planned source control activities. • The Contractor shall designate individuals responsible for inspection, maintenance and repair activities, and filling out the inspection and maintenance reports. • The Contractor shall ensure that all BMPs are installed under the supervision of a certified SWPPP Inspector/Installer. • The Contractor shall designate an individual certified in SWPPP Site Management. The designated personnel shall be responsible for keeping the erosion and sediment controls used onsite in good working order. • An employee -training program will be developed and implemented to educate the prime contractor's employees about the requirements of the SWPPP. • All subcontractors, except the seeding and compost installer subcontractor, present on the job must have at least one member who can document certification in Construction Site Management. The seeding and compost installer contractor must submit documentation that at least one member of each team present on the job is certified as Inspector/Installer. S. Maintenance / Inspection Procedures: In addition to complying with the requirements of the NPDES II permit, the Erosion Control Supervisor shall complete the inspection and maintenance practices that will be used to maintain erosion and sediment controls as follows: 1. All control measures will be inspected at least once each week and following any storm event of 0.5 inches or greater. 2. All measures will be maintained in good working order; if a repair is necessary, it will be initiated within 24 hours of report. 3. Build up of sediment will be removed from inlet protection before it has reached one-half the height of the device. 4. Temporary and permanent seeding and mulch will be inspected for bare spots, washouts, and healthy growth. 5. Construction site vehicle exit locations must be inspected for evidence of off-site tracking onto paved surfaces. Tracked sediment must be removed from off-site paved surfaces within 24 hours of discovery. 6. A maintenance/inspection report will be written after each inspection. The report should include: a. Date and time of inspections b. Name of persons conducting inspections c. Findings of inspections, including recommendations for corrective actions d. Corrective actions taken since last inspection (including dates, times, and party completing maintenance activities) e. Date and amount of rainfall events since last inspection report f Documentation of changes made to SWPPP SWPPP Page 12 of 13 HR Green, Inc. Chick-fil-A Chanhassen, MN Chick-fil-A, Inc. 7. The Erosion Control Supervisor will be responsible for inspection of all erosion control materials and writing the inspection and maintenance report. The Contractor and /or their sub -contractor will be responsible for all maintenance and repair activities deemed necessary by the Engineer or Erosion Control Supervisor. T. Pollution Prevention Management Measures: The following pollution prevention measures shall be implemented for: • Solid Waste: 1.

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 10 Custom Soil Resource Report classes but ratherto separate the landscape into landforms or landform segmentsthat 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 nfsmall areas ioplanned, however, onsite investigation ioneeded Lo 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 incomposition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree oferosion, and other characteristics that affect their use. (}nthe basis ofsuch differences, asoil series isdivided into s(i/phases. Most ufthe areas shown unthe detailed soil maps are phases ofsoil series. The name ofosoil phase commonly indicates afeature that affects use ormanagement. For example, Alpha silt loam, U tu2percent slopes, ioaphase ofthe 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, UtoOpercent slopes, isanexample. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown asone unit onthe maps. Because ofpresent o/ anticipated uses of the map units in the survey area, it was not considered practical ornecessary tomap the soils ormiscellaneous 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 |pha'Betauwonuiation.0to2peruentw|opeo.iounexurnp|e An undifferentiated group is made up of two or more soils or miscellaneous areas that could bemapped individually but are mapped osone unit because similar interpretations can Uemade 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 nfall ofthem. Alpha and Beta soils, Uto2percent slopes, iounexample. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little nrnnvegetation. Rock outcrop iounexample. 11 Custom Soil Resource Report MEMM= Map Unit Setting National map unit symbol 2vvdk Elevation: 690 to 1,840 feet Mean annual precipitation 24to37inches Mean annual air temperature: 43 to 52 degrees F Frost -free period. 140to180days Farmland classification Prime farmland if drained Map Unit Composition Cordova and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transacts of the mapunit Setting Landform: Ground moraines Landform position (three-dimensional): Talf Down-slope shape: Linear Across -slope shape: Linear Parent material Fine -loamy till Typical profile Ap - 0 to 10 inches: clay loam A- 10 to 18 inches clay loam Btg - 18 to 38 inches: clay loam Cg - 38 to 79 inches:loam Properties and qualities Slope: 0 to 2 percent Depth to restrictive feature More than 80 inches Natural drainage class: Poorly drained Capacity of the most limiting layer to transmit water (Ksat): Moderately high to high (0.20 to 2.00 in/hr) Depth to water table About 0 to 8 inches Frequency of flooding: None Frequency of ponding: None Calcium carbonate, maximum in profile: 20 percent Salinity, maximum fnprofile: Nonsalineto very slightly saline {0.0 to 2.0 mmhos/cm) Available water storage in profile: High (about 11.2 inches) Interpretive groups Land capability classification (irrigated): None specified Land capability classification (nonirrigated): 2w Hydrologic Soil Group: CID Other vegetative classification: Sloping Upland, Acid (G1 03XS006MN) zm�- Le sueur Percent of map unit: 10 percent Landform: Ground moraines, hillslopes 12 Custom Soil Resource Report Landform position (two-dimensional): Summit Landform position (three-dimensional): Interfluve, tall Down-slopeshape: Convex, linear Across -slope shape Linear Other vegetative classification: Sloping Upland, Acid (G103XS006MN) Glencoe Percent of map unit: 5 percent Landform: Depressions Down-slope shape: Concave Across -slope shape Concave Ecological site: Pothole Marsh (R1 03XY002MN) Other vegetative classification Ponded If Not Drained (G1 03XS01 3MN) =*- Map Unit Setting National map unit symbol: 2tsjr Elevation 690 to 1,840 feet Mean annual precipitation 24to37inches Mean annual air temperature: 43 to 52 degrees F Frost -free period. 140to180days Fam7land classification Prime farmland if drained Map Unit Composition Glencoe and similar soils: 80 percent Minor components: 20 percent Estimates are based on observations, descriptions, and transects of the mapunit. &�.
