with this role must be implemented in accordance wth the plan and sufficient to satisfy subsection
(13) Provisions for erosion and sediment control on individual building lots regulated under die
original permit or a project site owner must include the following requirements:
(I) The individual alt operator, whether owning the property or acting as the agent of the
properly owner, shall be responsible for erosion and sediment control requirements associated
with activities on' individual Tots.
(22) Installation and maintenance ofa stable construction site access,
(3) Installation and maintenance of appropriate perimeter erosion and sediment control
measures prior to land disturbance.
(4) Sediment d h rg e and Hacking from each lot must b -.N throughout th prod

Curb In let Protection Mats
The Mat is designed to be attach ed over the top of the curb Inlet grate with plastic cable ties
(75# strength Min.). The overall dimen sion of the mat shall allow for 2" beyond the water Inlet
perforations in the casting. The exception to this would be along the top where the grate shall be
exposed to allow overflow durin g heavy storm events. The composite curb inlet protection mat
shall be a machine - produced mat of 100% coconut fiber matrix incorporated into a permanent
three -dimen sign al matting. There shall be 2 layers of matrix evenly distributed across the entire
width of the matting. There shall be 4 layers of super heavy duty UV stabilized polypropylene net
with 0.500.5" open nge and 2 layers ultra 1 envy du ty UV stabilized dramatically
corrugated(crimped) termedia to polypropylene netting with 0 . 5 " x 0 . 5" openings. The mat shall be
stitched with UV stabilized polypropylene at 1.50" spacing. This device should be used in
con jun aeon with oth er BMP's to maxim ize the efficiency of the erosion control plan.
The mats are to be checked every two weeks and other every storm even t for maintenance
and /or repair and replacement

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

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 1/2 in (13 mm) long
shall be used, Filter material shall not be
stapled to existing trees.
7, The trench shall be backfilletl and the soli
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 filter (s roll shall the length sod in a

trench. The fabric shall not extend more than
3 ft (0.9 m) 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
and 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 6 in
(203 mm) deep. Install fence with stakes an
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
trench with soil material, and compact. Join silt
fence sections by overlapping sections and
nailing with lath to the nearest post. Inspect
twice a week and after each storm event,
repairing. as needed and removing sediment
deposits when they reach one -half the fence
height.

Map Unit: Bs - Brookston silt clay loam, 0 to 2 percent slopes
Brookston silty clay loam (0 to 2 percent slopes) (Bs).- -Some of this soil is in large tracts within
which are irregularly shaped islandlike areas of lighter colored soils, and some of it is in drainageways
and small depressions surrounded by lighter colored soils. This soil has the profile described as
representative of the series.
The content of organic matter is high in this soil. Wetness is the main limitation that affects use and
management.
If this Brookston soil is adequately drained, it is suited to all crops commonly grown in the county.
Under proper management it can be used intensively for row crops. Its limitations for uses associated
with residential development are severe. Capability unit llw -1: tree and shrub suitability group 1.
Map Unit: CrA - Crosby silt loam, 0 to 2 percent slopes
CrA -- Crosby silt loam, 0 to 2 percent slopes
This is a somewhat poorly drained soil and has a seasonal high watertable at 0.5 to 2.0 ft. and is on rises on
uplands. Slopes are 0 to 2 percent. The native vegetation is hardwoods. The surface layer is silt loam and has
moderately low or moderate organic matter content (1.0 to 3.0 percent). Permeability is very slow (c 0.06
in/hr) in the most restrictive layer above 60 inches. Available water capacity is moderate (6.2 inches in the
upper 60 inches).The pH of the surface layer in non -limed areas is 5.1 to 6.0. Droughtiness and wetness are
management concerns for crop production. This soil responds well to tile drainage.
