r �r✓ MAINTENANCE PLAN
I.E.=51.72' 1. All erosion and sediment control practices will be checked
for stability and operation following every runoff• -•producing
4 rainfall but in no case less than once every week. Any
needed repairs will be made immediately to maintain oil
practices as designed.
/ 2. All construction entrances will be periodically topdressed
r with an additional 2 inches of #4 stone to maintain proper
depth. Any sediment that is tracked into the street will
LE.=5iso' be immediately removed.
J. Sediment will be removed from the sediment trap and block
and gravel inlet protection device when storage capacity
1 has been approximately 509 filled. Gravel will be cleaned
or replaced when the sediment pool no longer drains
properly.
QO 4. Sediment will be removed from the sediment fence when it
becomes 0.5 deep at the fence. The sediment fence will
be repaired as necessary to maintain Ki barrier.
5. The sediment basin will be cleaned out when the level of
*ICE sediment reaches 2.0 feet below the top of the riser.
Gravel will be cleaned or replaced when the sediment pool
no longer drains properly.
6. t4l seeded areas will be fertilized, reseeded as necessary,
and mulched according to specifications in the vegetative
plan to maintain a vigorous, dense vegetative cover.
