[Ord. No. 8-1997, § 15(Q)(1), 7-15-1997]
All activities which involve filling, grading, excavation or
other similar activities which result in unstabilized soil conditions
and which require a permit shall require a written soil erosion and
sedimentation control plan. The plan shall be submitted to the permitting
authority for approval and shall include, where applicable, provisions
for:
(1) Mulching and revegetation of disturbed soil.
(2) Temporary runoff control features such as hay bales, silt fencing
or diversion ditches.
(3) Permanent stabilization structures such as retaining walls or riprap.
[Ord. No. 8-1997, § 15(Q)(2), 7-15-1997]
In order to create the least potential for erosion, development
shall be designed to fit with the topography and soils of the site.
Areas of steep slopes where high cuts and fills may be required shall
be avoided wherever possible, and natural contours shall be followed
as closely as possible.
[Ord. No. 8-1997, § 15(Q)(3), 7-15-1997]
Erosion and sedimentation control measures shall apply to all
aspects of the proposed project involving land disturbance, and shall
be in operation during all stages of the activity. The amount of exposed
soil at every phase of construction shall be minimized to reduce the
potential for erosion.
[Ord. No. 8-1997, § 15(Q)(4), 7-15-1997]
Any exposed ground area shall be temporarily or permanently
stabilized within one week from the time it was last actively worked,
by use of riprap, sod, seed, and mulch, or other effective measures.
In all cases, permanent stabilization shall occur within nine months
of the initial date of exposure. In addition:
(1) Where mulch is used, it shall be applied at a rate of at least one
bale per 500 square feet and shall be maintained until a catch of
vegetation is established.
(2) Anchoring the mulch with netting, peg and twine or other suitable
method may be required to maintain the mulch cover.
(3) Additional measures shall be taken where necessary in order to avoid
siltation into the water. Such measures may include the use of staked
hay bales and/or silt fences.
[Ord. No. 8-1997, § 15(Q)(5), 7-15-1997]
Natural and manmade drainageways and drainage outlets shall
be protected from erosion from water flowing through them. Drainageways
shall be designed and constructed in order to carry water from a twenty-five-year
storm or greater, and shall be stabilized with vegetation or lined
with riprap.
