RILEY PURGATORY BLUFF CREEK WATER SHED DISTRICT EROSION CONTROL NOTES:
a. Natural topography and soil conditions must be protected, including retention onsite of
native topsoil to the greatest extent possible.
b. Additional measures, such as hydraulic mulching and other practices as specified by the
District must be used on slopes of 3:1 (H:V) or steeper to provide adequate stabilization.
c. Final site stabilization measures must specify that at least six inches of topsoil or organic
matter be spread and incorporated into the underlying soil during final site treatment
wherever topsoil has been removed.
d. Construction site waste such as discarded building materials, concrete truckwashout,
chemicals, litter and sanitary waste must be properly managed.
e. All temporary erosion and sediment control BMPs must be maintained until completion of
construction and vegetation is established sufficiently to ensure stability of the site, as
determined by the District.
f. All temporary erosion and sediment control BMPs must be removed upon final
stabilization.
g. Soil surfaces compacted during construction and remaining pervious upon completion of
construction must be decompacted through soil amendment and/or ripping to a depth of
18 inches (8 inches for single-family home properties) while tatting care to avoid utilities,
tree roots and other existing vegetation prior to final revegetation or other stabilization.
h. All disturbed areas must be stabilized within 7 calendar days after land -disturbing work
has temporarily or permanently ceased on a property that drains to an impaired water,
within 14 days elsewhere.
I. The permittee must, at a minimum, inspect, maintain and repair all disturbed surfaces and
all erosion and sediment control facilities and soil stabilization measures every day work is
performed on the site and at least weekly until land -disturbing activity has ceased.
Thereafter, the permittee must perform these responsibilities at least weekly until
vegetative cover is established. The permittee will maintain a log of activities under this
section for inspection by the District on request.
Activities must be conducted so as to minimize the potential transfer of aquatic invasive species (e.g.,
zebra mussels, Eurasian watermilfoil, etc.) to the maximum extent possible.
