<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. Use horizontal slope grading
<br />3. Install erosion control around any temporary dirt stockpile areas.
<br />4. All septic areas to be fenced off for protection. Protection to extend a
<br />minimum of 20' outside of septic 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. The contractor shall schedule his operations to minimize 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 flatter 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.
