The site is located at the southeast intersection of Lyman Boulevard and Audubon Road. The SWPPP is prepared in accordance with the National Pollutant Discharge Elimination System (NPDES) regulations as established by the Clean Water Act. This report shall be on the site at all times during construction. P -1 The owner must also keep this SWPPP on file for three years after submittal of the Notice of Termination. The following are outlined in this SWPPP: 952 — Existing site conditions — Proposed site conditions — Control measures for storm water pollution prevention during construction — Control measures for storm water pollution prevention after construction — Inspection and maintenance procedures 2 EXISTING SITE CONDITIONS The site consists predominately of Type "B" soils; however, Type "A ", "C" and "D" also exist in smaller areas within the site boundary. Curve numbers were obtained from "Technical Release 55: Urban Hydrology for Small Watersheds." For existing conditions, curve numbers ranging between 60 and 81 were used for variable conditions extending from woodlands to contoured and terraced row crops in good hydrologic condition, respectively. During pre — developed conditions, all of the storm water entering the site is conveyed towards Bluff Creek. Therefore Bluff Creek was used as the design point to determine the rate of runoff from the project as well as areas to the east. Refer to the drainage map for its location. 3 PROPOSED SITE CONDITIONS For proposed conditions, a broader reach of curve numbers were used to model the site. These curve numbers ranged from 60 for woodlands to 100 for open water. Most of the site was modeled with a curve number of 75 for 1/4 acre residential lots with Type "B" soils. The remainder of the disturbed portion of the site was assigned a curve number of 98 for paved roads and roofs. Curve numbers remained unchanged for undisturbed areas. Three NURP ponds are incorporated into the development. The third NURP pond (P -3) located on the southeast portion of the property is being designed by a separate consulting firm to accommodate area within the site as well as runoff from upland areas east and west of the site boundary. The runoff from the upland areas will be conveyed to the site through a subsurface drainage network located beneath the city collector street. All of the storm water treatment ponds propose to convey treated runoff to Bluff Creek an Impaired Water. Pond P -1 sends runoff to an adjacent wetland located to the north via a concrete pipe. The wetland conveys this treated runoff to the creek. Pond P -2 conveys runoff to an adjacent wetland located to the west through a concrete pipe. In turn, the wetland carries this treated runoff to the creek. Wetland Basin W —A collects storm water from rear yard drainage as well as upland area further east of the site. In the event of a large storm, treated runoff would be conveyed overland to the south. The collector street would carry the overflow to treatment pond P -3.

The table below summarizes the results. ** Min = 5.66 cfs per Acre of Pond Surface Area. 4 STORMWATER POLLUTION PREVENTION BEFORE AND DURING CONSTRUCTION The following storm water pollution prevention measures are shown in the plans and shall be implemented prior to construction: — Install silt fence around the perimeter of areas to be graded as shown on the grading and erosion control plan. — Contractor to notify the SWCD once silt fence is installed prior to grading commencing, and also 24 hours prior to the installation of the rain garden areas. — All temporary stockpiles must have silt fence around them to trap sediment. — Construct gravel construction entrances at field entrances to the site. — Inlet protection is to be provided for all storm water inlets. — These are the minimum anticipated Best Management Practices. As site and climatic conditions change so might the necessary BMPs. The following storm water pollution prevention measures are shown in the plans and shall be implemented during construction: — Phase grading work to minimize the duration that any disturbed soil is exposed. — Place wood fiber blanket on all steep slopes (3:1 or steeper) — Place minimum 6 inches of topsoil over areas when grading is complete. — Place minimum 1 -1/2 tons /acre of straw on all areas after reaching final grade with topsoil and anchor straw with either a straight disk or netting. — Seed and mulch or place sod on all disturbed areas within the following time frames: — Slopes greater than 3:1 — within 7 days — Slopes from 10:1 to 3:1 — within 14 days — Slopes flatter than 10:1 — within 21 days — Mulch shall be MnDOT 2575 Type I applied at 2 tons /acre. — Seeding following general mass grading activities shall be MnDot 250GR applied ® 70 Ibs /ac unless specified otherwise. — Protect disturbed areas, including stockpiles, that are not completed but will remain inactive for greater than 14 days with mulch, plastic sheeting, or temporary seeding — Locate stockpiles a minimum 100 feet from catch basin inlets, ponds, and site drainage routes — All inlet protection devices shall be installed within 24 hours of installation. — All outlets shall be furnished with energy dissipating devices per plan. — Concrete trucks will utilize the concrete washout area shown on the plans to wash and rinse their equipment prior to leaving the site. After concrete work is complete, any remaining debris will be collected and removed from the site — Remove any sediments that have been tracked onto public streets within 24 hours — Removed any spill of fuel, oil, or other chemical immediately upon detection — Collect all construction debris in dumpsters and roll —off boxes — Store construction materials in an orderly manner — Inspect pollution control measures as specified in Section 6 — Repair silt fences, inlet protection gravel construction entrances and other erosion and sediment controls as needed.

See specifications for permanent seed mixtures. — Silt fence, inlet protection and other erosion and sediment control devices will be removed after vegetation is established — Storm water catch basins, manholes, pipe, and ponds will be maintained by the City of Chanhassen in accordance with their Storm water Management Plan once project has been accepted by the City. — Stabilization by uniform perennial vegetative cover (70% density) — Drainage ditches stabilized — Clean out sediment from conveyances and sedimentation basins (return to design capacity) — Distribute homeowner factsheet to builders and homeowners — Submit notice or termination 6 SWPPP INSPECTIONS Inspections shall be conducted every seven days or within 24 hours after a rainfall event exceeding 0.5 inches.
