MAINTENANCE PLAN
1, ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE CHECKED FOR STABILITY
AND OPERATION FOLLOWING EVERY RUNOFF -PRODUCING RAINFALL, BUT IN NO CASE,
LESS THAN ONCE EVERY WEEK. ANY NEEDED REPAIRS WILL BE MADE IMMEDIATELY TO
MAINTAIN ALL PRACTICES AS DESIGNED.
2. ALL CONSTRUCTION ENTRANCES WILL BE PERIODICALLY TOP -DRESSED WITH AN
ADDITIONAL 2 INCHES OF #4 STONE TO MAINTAIN PROPER DEPTH. ANY SEDIMENT THAT
IS TRACKED INTO THE STREET WILL BE IMMEDIATELY REMOVED.
3. SEDIMENT WILL BE REMOVED FROM THE SEDIMENT TRAP AND BLOCK AND GRAVEL
INLET PROTECTION DEVICES WHEN STORAGE CAPACITY HAS BEEN APPROXIMATELY 50%
FILLED. GRAVEL WILL BE CLEANED OR REPLACED WHEN THE SEDIMENT POOL NO
LONGER DRAINS PROPERLY.
4. SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN IT BECOMES
.5 FEET DEEP AT THE FENCE. THE SEDIMENT FENCE WILL BE REPAIRED AS NECESSARY
TO MAINTAIN A BARRIER. SILT FENCE STAKES WILL BE SPACED 6 FEET APART UNLESS
A WIRE BACKING IS USED WITH 8 FOOT STAKE SPACING.
5. THE SEDIMENT BASIN WILL BE CLEANED OUT WHEN THE LEVEL OF THE SEDIMENT
REACHES 2.0 FEET BELOW THE TOP OF THE RISER. GRAVEL WILL BE CLEANED AND
REPLACED WHEN THE SEDIMENT POOL NO LONGER DRAINS PROPERLY.
6. ALL SEEDED AREAS WILL BE FERTILIZED, RESEEDED AS NECESSARY, AND MULCHED
ACCORDING TO THE SPECIFICATIONS IN THE VEGETATIVE PLAN TO MAONTAIN A
VIGOROUS, DENSE VEGETATIVE COVER.
STABILIZATION NOTES
ALL DISTURBER AREAS WILL BE STABILIZED WITHIN 15 DAYS OF CEASE OF ANY PHASE
OF ACTIVITY. THIS INCLUDES SLOPES, SWALES, STOCKPILES AND ANY OTHER
UNSTABILIZED AREAS.

SOIL EROSION AND SEDIMENTATION CONTROL PLAN
Construction Schedule
1. Pre construction meeting with surveyor, grading contractor, owners and Engineer.
A meeting will take place involving all parties involved in the construction process. The soil
erosion and storm water plans will be discussed, as well as the sequence and BMP's to be in place before,
during and after construction.
2. Temporary Gravel Construction Entrance/Exit-Practice 6.06
A temporary gravel construction entrance/exit will be installed at the entrance to the site.
3. Sediment Fence - Practice 6.62
A sediment fence will be erected around the project boundaries as shown on the plan. This fence
will stay in place until the tract is stabilized rhith suitable ground cover and all grading is complete.
Sediment fence will also be erected around the top of the retaining wall when backfill reaches within 18" of
the top of the wall.
4. Temporary Sediment Trap - Practice 6.60
PROJECT BOUNDARY/ Stormwater pond to serve as temporary sediment trap, to be constructed before heavy grading
begins.
DRAINAGE AREA 5. Outlet Stabilization Structure - Practice 6.41
j' Outlet stabilization is to be constructed as shown on the plan.
j 6. Land Grading - Practice 6.02
Filling of the lot and construction of the retaining wall will begin and allow the final grades to be
set.
SLOPE SIDEWALK TO
PROPERTY 4" ; I'
7. COnstruction of Buildings
Construction of buildings will proceed to the point where heavy equipment will no longer be
needed.
8. Utility Installation
Underground utilities are to be installed and swales and other BMP's are to be repaired as soon as
possible. Reseeding of areas disturbed by utility work is to take place no later than 15 days after
installation is complete.
9. Paving
10. Removal of Temporary Sediment Traps
Prior to final surface stabilization, temporary sand traps are to be removed. Check dams may be
constructed as shown on the plan.
11. Surface Stabilization
All disturbed surfaces that are not paved are to be stabilized accorded to the vegetative plan. All
swales are to be stabilized with straw and net within 5 days of seeding. In case of a severe rain event in the
interim, the swales will be reseeded before excelsior mat is installed.
