EROSION CONTROL. NOTES AND MAINTENANCE PLAN
1, All erosion and sediment control measures will be checked for stability and
operation following every runoff --producing rainfall, but in no case, less than
once every week and within 24 hours of every half —inch rainfall.
2. All points of egress will have construction entrances that will be periodically
top —dressed with an additional 2 inches of #4 stone to maintain proper depth.
They will be maintained in a condition to prevent mud or sediment from
leaving the site. Immediately remove objectionable material spilled washed or
tracked onto the construction entrance or roadways.
. Sediment will be removed from hardware cloth and gravel inlet protection,
black and gravel Inlet protection, rock doughnut inlet protection and rack pipe
inlet protection when the designed storage capacity has been half filled with
sediment. Rock will be cleaned or replaced when the sediment pool no longer
drains as designed. [debris will be removed from the rock and hardware clot;
to allow proper drainage. Silt sacks will be emptied once a week and after
every rain event. Sediment will be removed from around beaver darns, dandy
socks and socks canoe a week and after every rain event.
4, Diversion ditches will be cleaned out immediately to remove sediment or
obstructions from; the flaw area. The diversion ridges will also be repaired.
Swales must be temporarily stabilized within 21 calendar days of cease of any
phase of activity associated with a swal.
b. Sediment will be removed from behind the sediment fence when it becomes
half ---filled. The sediment fence will be repaired as necessary to maintain a
barrier. Stakes must be steel. Stakes spacing will be 6 feet max. with the
use of extra strength fabric, without wire backing. Stare spacing will be d
feet max. when standard strength fabric and wire backing are used. If rock
filters are designed at low points in the sediment fence, the rack will be
repaired or replaced if it become half —full of sediment, no longer drains as
designed or is damaged.
6. Sediment will be removed from sediment traps when the designed storage
capacity has been half filled with sediment. The rock will be cleaned or
replaced when the sediment pool no longer drains or when the rock is
dislodged. Baffles will be repaired or replaced if they collapse, tear,
decompose or became ineffective. They will be replaced promptly. Sediment
will be removed when deposits reach half the height of the 1st baffle.
Floating skimmers will be inspected and kept clean weekly.

They will be maintained in a condition to prevent mud or sedirnena from

. Sediment will be removed from hardware cloth and gravel inlet protection,
block and gravel inlet protection, rock doughnut inlet protection and rock pipe
inlet protection when the designed storage capacity has been half filled with
sediment. lock will be cleaned or replaced when the sediment pool no longer
drains as designed. [debris will be removed from the rock and hardware cloth
to callow proper drainage, Silt sacks will be emptied once a creek and rafter
every rain event. Sediment will be removed from around beaver drams, dandy
sacks and socks once a meek and after every rain event.
. Diversion ditches will be cleaned out immediately to remove sediment or
obstructions from the flow area. The diversion ridges will also be repaired.
Swales Faust be temporarily stabilized within 21 calendar days of cease of any
phase of activity associated with a swale.
5. Sediment will be removed from behind the sediment fence when it becomes
half—filled. The sediment fence will be repaired as necessary to maintain a
barrier. Stapes must be steel. Stakes spacing will be 6 feet max. with the
use of extra strength fabric, without wire backing. Stare spacing will be 8
feet max. when standard strength fabric and wire backing are used. If rock
filters are designed at low points in the sediment fence, the rack will be
repaired or replaced if it become half —full of sediment, no longer drains as
designed or is damaged.
6. Sediment will be removed from sediment traps when the designed storage
capacity has been half filled with sediment. The rock will be cleaners or
replaced when the sediment pool no longer drains or when the rock is
dislodged. Baffles will be repaired or replaced if they collapse, tear,
decompose or become ineffective. They will be replaced promptly. Sediment
will be removed when deposits reach half the height of the 1st baffle.
Floating skimmers will be inspected and kepi clean weekly.
7. Sediment will be removed from the sediment basin when the design storage
capacity has !seers half filled with sediment. Rock will be cleaned or replaced
when the sediment pool no longer drains or if the rock is dislodged. Baffles
will be repaired or replaced if they collapse, tear, decompose or become
ineffective. They will be replaced promptly. Sediment will be removed from
baffles when deposits reach half the height of the 1st baffles Floating
skimmers will be inspected weekly and will be kept clean.
8. All seeded areas will be fertilized, reseeded as necessary and mulched
according to specifications in the vegetative plan to maintain a vigorous, dense
vegetative cover. All slopes will be stabilized within 21 calendar days. All
others areas will be stabilized within 15 working days.
9. Flocculants will be used to address turbidity issues. The pumps, tanks hoses
and inject systems will be checked for problems or turbid discharges daily.
