dard 1
permanent or temporary soil stabilization shall be applied to denuded areas
within seven days after final grade is reached on any portion of the site;
temporary soil stabilization shall be applied within seven days to
denuded areas that may not
be at final grade but will remain dormant for longer than 14 days;
permanent stabilization shall be applied to areas that are to be left
dormant for more than one year
2. Site NOT at
Final Grade -stabilize in 14 days
-temporarily seed
-mulch
-permanently stabilize if dormant > 1 year
3. Site at
Final -stabilize in 7 days (recommended immediately)
Grade -permanently or temporarily seed and mulch
-mulch/matting/straw
4. Minimum Stock Piles, Waste and Borrow Areas
Stan-
dard 2 during construction, soil stock piles and borrow areas shall be stabilized
or pro- tected with sediment trapping measures
mulch prevents erosion by protecting the surface from raindrop impact
and silt fence intercepts and detains from disturbed areas
5. Minimum Permanent Vegetation
Stan-
dard 3 permanent vegetation cover shall be established on denuded areas not
otherwise permanently stabilized (permanent vegetation shall not be
considered established until a ground cover is achieved that is uniform,
mature enough to survive, and will inhibit erosion *there is no %
