DANE COUNTY EROSION CONTROL <br /> APPLICATION CHECKLIST COMMENTS <br /> The following comments supplement the Dane County Erosion Control <br /> Application Checklist on page 5. Each comment heading relates to an item on the Dane <br /> County Checklist. <br /> 1. Description of How the Site Is To Be Developed <br /> For this report, a construction start date of October 1, 2008 was assumed. A <br /> completion date of October 1, 2009 was also assumed. All erosion control <br /> measures will be installed at the beginning of the construction operations. <br /> 2. Drawing of Site <br /> The Grading and Erosion Control Plan, Exhibit #3, shows the property lines, <br /> limits of disturbed area, land cover type, natural and artificial water features, <br /> and the location of all proposed erosion control practices for the site. <br /> 3. Direction of Flow of Runoff <br /> In general, the existing and proposed runoff drains from the west to east <br /> towards Lake Koshkonong. <br /> 4. Watershed Size for Each Drainage Area <br /> The drainage area is approximately 0.5 acres. <br /> 5. Provisions to Prevent Mud-tracking Off-site onto Public Thoroughfares <br /> The stone construction entrance will be maintained by the contractor in a <br /> condition which will prevent the track of mud or dry sediment onto the <br /> adjacent public streets. Sediment reaching the public road shall be removed <br /> by street cleaning (not hydraulic flushing)before the end of each workday. <br /> 6. Provisions to Prevent the Delivery of Sediment to the Stormwater System <br /> There are no storm sewer inlets on site and the erosion control measures will <br /> prevent sediment from discharging to stormwater facilities. <br /> 7. Minimize Sheet and Rill Erosion to 7.5 Tons/Acre/Year <br /> Universal Soil Loss Equation worksheets have been prepared and are included <br /> as Exhibit#4. The worksheets show that the expected soil loss is less than 7.5 <br /> tons/acre/year. <br /> 8. Provisions For Mitigating the Erosive Effect of Land Disturbing Activities <br /> The land disturbing activities are scheduled so that the period of disturbance is <br /> minimized. Disturbed areas will be temporary mulched within 8 months of <br /> initial disturbance and permanently restored within 1 year. Disturbed slopes <br /> greater than 20% will be temporary mulched within 7 days and permanently <br /> restored within 30 days. During construction, the erosion control items will <br /> be maintained so that they remain effective. All material deposited on public <br /> roads shall be cleaned or swept daily. <br /> Shoreland Erosion Control Report <br /> EB-01-08 <br /> 9/11/2008 6 <br />
