CERTIFICATE OF SURVEY FOR <br />STEPHEN D, PAULSON <br />OF TRACT A, R.L.S. NO. 1249 <br />HENNEPIN COUNTY, MINNESOTA <br />0 50 100 <br />200 <br />SCALE IN FEET <br />Temporary Erosion Control and Sequencing <br />1. Install perimeter control fencing per the standard detail plates. No more than <br />600 linear feet of silt fence should be continuous and collecting at one point. <br />Undulate the silt fence or use "simles" or crescents of silt fence. <br />2. Install a rock construction entrance per the standard detail plate. Rock pad <br />exits are needed where the site exits to the private drive. Rock pads should <br />be 3 inch rock, 6 inches deep, and 75 feet long and span the full width of the <br />exit. Geotextile fabric should be placed under the rock. <br />3. Use horizontal slope grading <br />4. Install erosion control around any temporary dirt stockpile areas. <br />5. The contractor for the project shall inspect all erosion control BMP's after <br />each rainfall and repair as necessary and remove sediment from silf fences <br />if it reaches 1/3 capacity. <br />6. 'f he contractor shall schodule his operations to min.;. -.:_3 ;the amount of <br />disturbed area at any given time. The contractor shall limit his activities <br />to the grading limits as shown. <br />7. Remove all temporary BMP's once the site has reached final stabilization (a <br />uniform perennial vegetative cover with a density of 70 percent over all pervious <br />surface areas). <br />Permanent Erosion Control <br />1. All exposed soils on site must be stabilized with in 3 days: <br />a. Stabilization on slopes flatter than 4:1 consists of disc -anchored <br />mulch and seed; stabilization on slopes steeper than 4:1 and in areas <br />of concentrated flows consists of erosion blankets and seed. <br />2. Temporary mulch and seed is needed for exposed areas which sit fallow for <br />3:1 or steeper in 7 days, 3:1 to 10:1 in 14 days, and flatter than 10:1 in 21 <br />days. Also open stockpiles need to have temporary stabilization if they are to <br />remain inactive for more than 7 days. <br />R - I <br />0 <br />OO SRT FEWE _--� ••" •mn. <br />.
