STORM WATER POLLUTION & PREVENTION NOTES:
(A) All storm water quality measures, including erosion and sediment control, necessary to comply
with this rule must be implemented in accordance with the plan and sufficient to satisfy subsection
(b).
(B) Provisions for erosion and sediment control on individual building lots regulated under the
original permit of a project site owner must include the following requirements:
(1) The individual lot operator, whether owning the property or acting as the agent of the
property owner, shall be responsible for erosion and sediment control requirements associated
with activities on individual lots.
(2) Installation and maintenance of a stable construction site access.
(3) Installation and maintenance of appropriate perimeter erosion and sediment control
measures prior to land disturbance.
(4) Sediment discharge and tracking from each lot must be minimized throughout the land
disturbing activities on the lot until permanent stabilization has been achieved.
(5) Clean-up of sediment must be redistributed or disposed of in a manner that is in
compliance with all applicable statutes and rules.
(6) Adjacent lots disturbed by and individual lot operator must be repaired and stabilized with
temporary or permanent surface stabilization.
(7) For individual residential lots, final stabilization meeting the criteria in section 7(b)(20) or
this rule will be achieved when the individual lot operator:
(A) completes final stabilization; or
(B) has installed appropriate erosion and sediment control measures for an individual lot prior to
occupation of the home by the homeowner and has informed the homeowner of the requirement for,
and benefits of, final stabilization. 7(b)(20) Final stabilization of a project site is achieved when:
(A) all land disturbing activities have been completed and a uniform (for example, evenly
distributed, without large bare areas) perennial vegetative cover with a density of seventy percent
(70%) has been established on all unpaved areas and areas not covered by permanent structures, or
equivalent permanent stabilization measures have been employed; and
(B) construction projects on land used for agricultural purposes are returned to its preconstruction
agricultural use or disturbed areas, not previously used for agricultural production, such as filter
strips and areas that are not being returned to their preconstruction agricultural use, meet the final
stabilization requirements in clause (A).

DrOD Inlet Protection Basket
It is the intent of this device to detain water for the purpose of allowing suspended solids
in the water to settle out before the water enters the storm structure. Some filtering will
occur as water passes through the device.
The bottom of this device is to seal against the flat outer part of the casting. The overall
dimension of the basket shall be no smaller than the water inlet perforations in the casting
and no . larger than the outer dimensions of the casting The height shall be 15"
The basket frame shall be welded wire mesh rolled or bent and welded to itself to fit the
casting. The wire size shall be no smaller than .149" dia. and openings no larger than 18
sq in. It is important that the bottom of the wire frame be smooth so as not to allow any
leakage between the basket and casting. The top of the basket shall be open to prevent
flooding during heavy storm events.
Fabric shall be woven polypropylene allowing 15-25gal/min/sq in. If non -woven fabric
is used, the maintenance intervals should be increased to replace silt laden fabric. The
fabric shall be attached to the frame and folded under the bottom to help seal against the
c asting.
This device should be used in conjunction with other Best Management Practices to
maximize the efficiency of the erosion control plan.

1. Synthetic filter fabric shall be a pervious sheet
of propylene, nylon, polyester or ethylene yarn
and shall be certified by the manufacturer or
supplier as conforming to the following
Y
requirements: synthetic filter fabric shal
l
q
contain ultraviolet ray inhibitors and stabilizers
to provide a minimum of 6 months of expected
usable construction life.
2. Burlap shall be 10 ounces per square yard
fabric.
3. Posts for silt fences shall be either 4 in
(10 cm ) diameter wood or 1.33 Ibs / ft ( 2
kg/m) steel with a minimum length of 5 ft (1.5
m). Steel posts shall have projections for
fastening wire to them.
4. Stakes for filter barriers shall be 1 x 2 in (2.5 x
5 cm) wood or equivalent metal with a
minimum length of 3 ft (0.9 m).
5. Wire fence reinforcement for silt fences using
standard strength filter cloth shall be a
minimum of 3 ft (0.9 m) in height, a minimum
of 14 gauge and shall have a maximum mesh
spacing of 6 in (15 cm).
Filter Barrier
1. This sediment barrier may be constructed
using burlap or standard strength synthetic
filter fabric. It is designed for low or moderate
flows.
2. The height of a filter barrier shall be a
minimum of 15 in (381 mm) and shall not
exceed 18 in(457 mm).
3. Burlap or standard strength synthetic filter
fabric shall be purchased in a continuous roll
and cut to the length of the barrier to avoid the
use of1 oints.
4. The stakes shall be spaced a maximum of 3
feet (0.9 m) apart at the barrier location and
driven securely into the ground - a minimum of
8in (203 mm).
5. A trench shall be excavated approximately 4
in (102 mm) wide and 4 in (102 mm) deep
along the line of stakes and upslope from the
barrier.
6. The filter material shall be stapled to the
wooden stakes, and 8 in (203 mm) of the
fabric shall be extended into the trench. Heavy
duty wire staples at least 112 in (13 mm) long
shall be used. Filter material shall not be
stapled to existing trees.
7. The trench shall be backfilled and the soil
compacted over the filter material.
8. If a filter barrier is to be constructed across a
ditch line or Swale, the barrier shall be of
sufficient length to eliminate end flow, and the
plan configuration shall resemble an arc or
horseshoe with the ends oriented upslope.
9. Filter barriers shall be removed when they
have served their useful purpose, but not
before the upslope area has been
permanently stabilized.
Silt Fence
1. This sediment barrier utilizes standard
strength or extra strength synthetic filter
fabrics. It is designed for situations in which
only sheet or overland flows are expected.
2. The height of a silt fence shall not exceed 3 ft
(0.9 m); (higher fences may impound volumes
of water sufficient to cause failure of the
structure).
3. The shall filter fabric I I be purchased
sed in a
continuous roll cut to the length of the barrier
to avoid the use ofjoints. When joints are
necessary, filter cloth shall be spliced together
only at a support post, with a minimum 6 in
(152 mm ) overlap, and securely sealed.
4. Posts shall be spaced a maximum of 10 ft (3
m) apart at the barrier location and driven
securelyinto the round minimum of 12 in
9 (
(305 mm). When extra strength fabric is used
without the wire support fence, post spacing
shall not exceed 6 ft 1.85 m).
5. A trench shall be excavated approximately 4
in 102 mm wide and 8 in 203 mm)deep
alongthe line of posts and upslope from the
p
barrier.
6. When standard strength filter fabric is used, a
wire mesh support fence shall be fastened
securelyto the upslope side of the posts usin
9
heavy duty wire staples at least 1 in (25 mm)
long, tie wires or hog rings. The wire shall
extend into the trench a minimum of 2 in (51
mm) and shall not extend more than 3 ft ( 0.9
m) above the original ground surface.
7. The standard strength filter fabric shall be
stapled or wired to the fence, and 8 in (203
mm) of the fabric shall be extended into the
trench. The fabric shall not extend more than
3 ft (0.9 rn) above the original ground surface.
8. When extra strength filter fabric and closer
post spacing are used, the wire mesh support
fence may be eliminated. In such cases the
filter fabric is stapled or wired directly to the
posts.
9. The trench shall be backfilled and the soil
compacted over the filter fabric.
10. Silt fences shall be removed when they have
served their useful purpose, -but not before the
upslope area has been permanently
stabilized. Install parallel to the contour of the
land and with no more than 0.25 acre (0.1
hectare) drainage area per 100 ft (30 m) of
fence. Extend ends upslope enough to allow
water to pond behind the fence. Fence posts
buried a minimum of 15 in (381 mm).
Excavate a trench 4 in (102 mm) wide and 8 in
(203 mm) deep. Install fence with stakes on
the down slope side. Bury 12 in (305 mm) of
fabric in the trench, extending the bottom 4 in
(102 mm) toward the upslope side. Backfill
i material and compact, Join i trench with soil p t, silt
fence sections by overlapping overla in sections and
nailing with lath to the nearest past. Inspect
twice a week and after each storm event,

Br--Brookston silty clay loam
This poorly drained soil has a seasonal high watertable above the surface or within 1.0 ft. and
is in depressions. Slopes are 0 to 2 percent. The native vegetation is water tolerant grasses and
hardwoods. The surface layer is silty clay loam and has moderate or high organic matter
content (2.0 to 5.0 percent). Permeability is moderately slow (0.2 to 0.6 in/hr) in the most
restrictive layer above 60 inches. Available water capacity is high (10.0 inches in the upper 60
inches).The pH of the surface layer in non -limed areas is 6.1 to 7.3. This soil is hydric.
Wetness is a management concern for crop production. This soil responds well to tile
