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 topdressed
with an additional 2 inches of #4 stone to maintian 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 device when storage capacity
has been approximately 50% tilled. Gravel will be cleaned
or replace when the sediment pool no longer drains properly.
4. Sediment will be removed from behind the sediment fence
when it becomes 0.5 feet deep at the fence. The sediment
fence will be repaired as necessary to maintain a barrier.
5. The sediment basin will be cleaned out when the level of
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. All seeded areas will be fertilized, reseeded as necessary,
and mulched according to specifications in the vegetative
plan to maintain a vigorous, dense vegetativie cover.
STABILIZATION NOTES
1. All slopes will be stabilized within 15 days of cease of any
phase of grading.
2. All other areas will be stabilized within 15 days of cease of
any phase of grading.
-CONSTRUC77ON SCHEDULE
1. Obtain plan approval and other applicable permits,
2. Hold pre -construction meeting at least one week
prior to beginning construction.
3. InstaftlMaintain temporary construction entrancelexit.
4. Before clearing and grading of the site, install silt
fencing at the base of slopes to restrict movement of
sediment from the site.
5_ Begin clearing and grading at Pond location.
6. Construct Wet Detension Basin. No further disturbance is
allowed until pond complete.
7. Install temporary construction ditching with necessary check dams.
8. Install main storm piping and catch basins from the pond to the roadways.
9. Begin clearing and grading of roadways.
10. Install Inlet Protection for catch basins and curb inlets
to restrict movement of sediment from the site.
11Final grading will be of individual lots to drain to roadways
and catch basins.
12. All erosion and sediment control practices will be
inspected bi-weekly and after each rainfall event.
Needed repairs will be made immediately.
13 After the entire covered area is stabilized, all temporary
measures will be removed and permanent vegetative repairs
to be completed.
VEGETATION PLAN
1. After complete stabilization of the entire covered area,
top cover soils will be roughened by making 1' -T deep
grooves perpendicular to the slope.
2 Spread lime (agricultural limestone) evenly over the area
at a rate of 1.5 tons/acre; spread 1 Q-10--16 fertilizer at rate
specified and incorporate into the top 6" of soil.
3. Loosen surface prior to applying seed.
4. Broadcast seed at recommended rates,
5. Rake seed into the soil and lightly pack to establish good contact.
6. Mulch with 4000 Ibfacre grain straw or equivalent and anchor by
weighted farm disc set nearly straight or other mulch anchoring tool.
7. blow as needed and refertilize in late winter or early spring by topdressing
with 16- 10-10 fertilizer.
8. Soil stabilization shall be achieved on any area of a site where Iand-
disturbing activities have temporarily or permanently ceased according to
the following schedule: 1) All perimeter dikes, swales, ditches, perimeter
slopes steeper than 3:1 shall be provided temporary or permanent
stablization with ground cover as soon as practicable but in any event
within 7 calendar days from the last land -disturbing activity. 2) All other
disturbed areas shall be provided temporary or permanent stabilization
with ground cover as soon as practicable, but in any event within 14
calendar days from the last land -disturbing activity.

NOTES FOR DETENTION BASIN
CONSTRUCTION SPECIFICATIONS
SITE PREPARATIONS - CLEAR, GRUB AND STRIP TOPSOIL FROM THE SITE AREA OF THE NEW POND TO REMOVE TREES, VEGETATION,
ROOTS AND OTHER OJECTIONABLE MATERIAL. TO FACILITATE SEDIMENT CLEANOUT, STOCKPILE ALL TOPSOIL OR SOIL CONTAINING
ORGANIC MATTER FOR USE ON THE OUTER SHELL OR THE EMBANKMENT TO FACILITATE VEGETATIVE ESTABLISHMENT. PLACE
TEMPORARY SEDIMENT CONTROL MEASURES BELOW THE BASIN AS NEEDED.
-- THE BARREL R BARREL S WATER -TIGHT STRUCTURAL
CONDUIT SPILLWAYS SECURELY ATTACH THE RISER TO E O .TUB TO MAKE A WATER TIGH
-TIGHT ASSEMBLIES.
MBLIES. PLACE THE BARREL
CONNECTIN
SECURE ALL CONNECTIONS BETWEEN BARREL SECTIONS BY APPROVED WATER
AND RISER ON A FIRM, SMOOTH FOUNDATION OF IMPERVIOUS SOIL. DO NOT USE PERVIOUS MATERIAL SUCH AS SAND, GRAVEL, OR
CRUSHED STONE AS BACKFILL AROUND THE PIPE OR ANTI -SEEP COLLARS. PLACE THE FILL MATERIAL AROUND THE PIPE SPILLWAY
IN 4 INCH LAYERS AND COMPACT IT UNDER AND AROUND THE PIPE TO AT LEAST THE SAME DENSITY AS THE ADJACENT
EMBANKMENT. CARE MUST BE TAKEN NOT TO RAISE THE PIPE FROM FIRM CONTACT WITH ITS FOUNDATION WHEN COMPACTING
UNDER THE PIPE HAUNCHES. PLACE A MINIMUM DEPTH OF 2 FT. OF HAND -COMPACTED BACKFILL OVER THE PIPE SPILLWAY
BEFORE CROSSING IT WATH CONSTRUCTION EQUIPMENT. ANCHOR THE RISER IN PLACE BY CONCRETE OR OTHER SATISFACTORY
MEANS TO PREVENT FLOTATION'. IN NO CASE SHOULD THE PIPE CONDUIT BE INSTALLED BY CUTTING A TRENCH THROUGH THE DAM
AFTER THE EMBANKMENT IS COMPLETE.
EMERGENCY SPILLWAY - INSTALL THE EMERGENCY SPILLWAY IN UNDISTURBED SOIL. THE ACHIEVEMENT OF PLANNED ELEVATIONS,
GRADE, DESIGN WIDTH, AND ENTRANCE AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCCESSFUL OPERATION OF THE
EMERGENCY SPILLWAY.
INLETS - DISCHARGE WATER INTO THE POND IN A MANNER TO PREVENT EROSION. USE OUTLET PROTECTION AT EACH PIPE TO
PREVENT EROSION OF THE POND FLOOR.
EROSION CONTROL - CONSTRUCT THE STRUCTURE SO THAT THE DISTURBED AREA IS MINIMUMIZED. DIVERT SURFACE WATER AWAY
FROM BARE AREAS. COMPLETE THE EMBANKMENT BEFORE THE AREA IS CLEARED.
SAFETY - SEDIMENT BASINS MAY ATTRACT CHILDREN AND CAN BE DANGEROUS. AVOID STEEP SIDE SLOPES, AND MARK BASINS
WITH WARNING SIGNS IF TRESPASSING IS LIKELY.
MAINTENANCE NOTES FOR. DETENTION BASIN
1. AFTER EVERY SIGNIFICANT RUNOFF PRODUCING RAINFALL EVENT AND AT LEAST MONTHLY:
A INSPECT THE DETENTION BASIN SYSTEM FOR SEDIMENT ACCUMULATION, EROSION, TRASH
ACCUMULATION, VEGETATED COVER, AND GENERAL CONDITION.
B: CHECK AND CLEAR THE ORIFICE OF ANY OBSTRUCTIONS SUCH THAT DRAWDOWN OF THE TEMPORARY
POOL OCCURS WITHIN 2 TO 5 DAYS AS DESIGNED.
2. REPAIR ERODED AREAS IMMEDIATELY, RE --SEED AS NECESSARY TO MAINTAIN GOOD VEGETATIVE COVER,
MOW VEGETATIVE COVER TO MAINTAIN A MAXIMUM HEIGHT OF SIX INCHES, AND REMOVE TRASH AS NEEDED.
3. INSPECT AND REPAIR THE COLLECTION SYSTEM (I.E. CATCH BASINS, PIPING, SWALES, RIPRAP, ETC.)
QUARTERLY TO MAINTAIN PROPER FUCTIONING.
4.. REMOVE ACCUMULATED SEDIMENT FROM THE DETENTION BASIN SYSTEM SEMI-ANNUALLY OR WHEN DEPTH
IS REDUCED TO 75% OF THE ORIGINAL DESIGN DEPTH_ REMOVED SEDIMENT SHALL BE DISPOSED OF IN AN
APPROPRIATE MANNER AND SHALL BE HANDLED IN A MANNER THAT WILL NOT ADVERSELY IMPACT WATER
QUALITY (I.E. STOCKPILING NEAR A WET DETENTION BASIN OR STREAM, ETC.)
THE MEASURING DEVICE USED TO DETERMINE THE SEDIMENT ELEVATION SHALL BE SUCH THAT IT WILL GIVE
AN ACCURATE DEPTH READING AND NOT READILY PENETRATE INTO ACCUMULATED SEDIMENTS.
WHEN THE PERMANENT POOL DEPTH READS 1 FOOT IN THE POOL, THE SEDIMENT SHALL BE REMOVED.
5. IF THE BASIN MUST BE DRAINED FOR AN EMERGENCY OR TO PERFORM MAINTENANCE, THE FLUSHING OF
SEDIMENT THROUGH THE EMERGENCY DRAIN SHALL BE MINIMIZED TO THE MAXIMUM EXTENT PRACTICAL.
6. ALL COMPONENTS OF THE DETENTION BASIN SYSTEM SHALL BE MAINTAINED IN FOOD WORKING ORDER.
CONSTRUCTION SCHEDULE
1. Obtain plan approval and other applicable permits.
2. Hold pre -construction meeting at least one week
prior to beginning construction.
3. Install/Maintain temporary construction entrancelexit.
4. Before clearing and grading of the site, instal( silt
fencing at the base of slopes to restrict movement of
sediment from the site,
5. Begin clearing and grading of the site.
6. Install storm piping, catch basins, and curb inlets.
7. Install Inlet Protection for catch basins and curb inlets
to restrict movement of sediment from the site.
8. All erosion and sediment control practices will be
inspected bi-weekly and after each rainfall event.
Needed repairs will be made immediately.
9. After the entire covered area is stabilized, all temporary
measures will be removed and permanent vegetative repairs
to be completed.
VEGETATION PLAN
1. After complete stabilization of the entire covered area,
top cover soils will be roughened by making 1 "-2" deep
grooves perpendicular to the slope.
2. Spread lime (agricultural limestone) evenly over the area
at a rate of 1.5 tons/acre; spread 10-10-10 fertilizer at rate
specified and incorporate into the top 6" of soil.
3. Loosen surface prior to applying seed.
4. Broadcast seed at recommended rates.
5. Rake seed into the soil and lightly pack to establish good contact.
6. Mulch with 4000 Iblacre grain straw or equivalent and anchor by
weighted farm disc set nearly straight or other mulch anchoring tool.
7. Mow as needed and re€ertil'Ize in late winter or early spring by topdressing
with 10- 1040 fertilizer.
6. Graded surfaces shall not be exposed without grass coverage for more
than 15 days. if grades are not complete and exposure is more than
15 days, temporary seed as specified.
MAINTENANCE PLAN`
1.' All erosion and sediment control practices will be checked
for stability and operation following every runoff -producing
