CONTROL MEASURES

SOIL EROSION CONTROL MAINTENANCE

SCHEDULE AND NOTES.

1. DAILY INSPECTION SHALL BE MADE BY THE CONTRACTOR FOR EFFECTIVENESS OF

EROSION AND SEDIMENTATION CONTROL MEASURES, AND ANY NECESSARY

REPAIRS SHALL BE PERFORMED WITHOUT DELAY.

2. EROSION AND ANY SEDIMENTATION FROM WORK ON THIS SITE SHALL BE

CONTAINED ON THE SITE AND NOT ALLOWED TO COLLECT ON ANY OFF-SITE AREAS

OR IN WATERWAYS. WATERWAYS INCLUDE BOTH NATURAL AND MAN-MADE

OPEN DITCHES, STREAMS, STORM DRAINS, LAKES AND PONDS.

3. CONTRACTOR SHALL APPLY TEMPORARY EROSION AND SEDIMENTATION CONTROL

MEASURES WHEN REQUIRED AND AS DIRECTED ON THESE PLANS. CONTRACTOR

SHALL REMOVE TEMPORARY MEASURES AS SOON AS PERMANENT STABILIZATION

OF SLOPES, DITCHES AND OTHER CHANGES HAS BEEN ACCOMPLISHED.

4. STAGING OF THE WORK WILL BE DONE BY THE CONTRACTOR AS DIRECTED IN

THESE PLACES AND AS REQUIRED TO INSURE PROGRESSIVE STABILIZATION OF

DISTURBED AREAS.

5. SOIL EROSION CONTROL PRACTICES WILL BE ESTABLISHED IN EARLY STAGES OF

CONSTRUCTION BY THE CONTRACTOR. SEDIMENT CONTROL PRACTICES WILL BE

APPLIED AS A PERIMETER DEFENSE AGAINST ANY TRANSPORTING OF SILT OFF THE

SITE.

6. A CERTIFIED STORM WATER OPERATOR WILL BE NAMED ON THE MDEQ NOTICE OF

COVERAGE FOR NPDES AS REQUIRED.

7. ALL DISTURBED UPLAND AREAS ARE TO BE TOP SOILED AND SEEDED STANDARD

LAWN SEED MIXTURE AS FOLLOWS:

TOP-SOIL 3" IN DEPTH, GRASS SEED 210 LBS PER ACRE, FERTILIZER 150 LBS PER

ACRE, STRAW MULCH 1.5 TO 2 TONS PER ACRE.

8. ALL DISTURBED AREAS BELOW THE 100 YEAR ELEVATION IN THE DETENTION AREAS

ARE TO BE TOPSOILED AND SEEDED WITH WETLAND SEE MIXTURE AS FOLLOWS:

TOP-SOIL 3" IN DEPTH, WETLAND SEED MIXTURE (SEE SHEET C-9.2) AT 36 LBS PER

ACRE IN ADDITION TO STANDARD LAWN SEED MIXTURE AT 150 LBS PER ACRE,

FERTILIZER 150 LBS PER ACRE. STAKED MULCH BLANKET SHALL BE USED TO

PROTECT THE SEEDED SLOPES FROM EROSION.

ONCE SEEDED, NO MOWING SHALL BE ALLOWED BELOW THE 100 YEAR STORM

ELEVATION IN THE PONDS.

MARTIN LUTHER KING JR. BLVD., LANSING, MI 48906.

EMAIL: ROBERT.K.MACLEOD2.NFG@ARMY.MIL, MOBILE: 517-290-4991.

2. EARTHWORK SHALL BE LIMITED TO THE PROPOSED SITE AS SHOWN ON THE PLAN.

3. CONTRACTOR SHALL INSPECT THE SOIL EROSION/SEDIMENTATION CONTROL

DEVICES ONCE A WEEK AND/OR WITHIN 24 HOURS OF A RAINFALL EVENT WHICH

RESULTS IN A STORM WATER DISCHARGE FROM THE SITE. ANY DAMAGE TO

EROSION CONTROL MEASURES MUST BE REPAIRED IMMEDIATELY.

4. ALL MUD OR DEBRIS TRACKED ONTO EXISTING PUBLIC ROADS FROM THE SITE DUE

TO CONSTRUCTION SHALL BE PROMPTLY REMOVED BY THE CONTRACTOR.

5. SILT FENCE MAINTENANCE SHALL INCLUDE THE REMOVAL OF ANY BUILT-UP

SEDIMENT WHEN THE SEDIMENT HEIGHT ACCUMULATES TO 1/3 TO 1/2 OF THE

HEIGHT OF THE FENCE. THE CONTRACTOR IS RESPONSIBLE TO REMOVE, REPLACE,

RETRENCH OR RE-BACKFILL THE SILTATION FENCE SHOULD IT FAIL OR BE DAMAGED

DURING CONSTRUCTION.

6. PERMANENT STABILIZATION MUST BE COMPLETED WITHIN 30 DAYS OF FINAL

GRADING.

7. ACCESS ROADS MUST BE MAINTAINED AS NECESSARY, TO KEEP THEM EFFECTIVE,

NEW LAYERS OF STONE MAY BE ADDED AS OLD LAYERS BECOME COMPACTED.

STEPS SHOULD ALSO BE TAKEN TO REPAIR THE ACCESS ROADS IF RUTS OR

PONDING WATER APPEARS.

8. INLET FILTERS SHOULD BE INSPECTED FOR BUILDUP OF SILT AND OTHER DEBRIS.

THIS IS EVIDENT IF GEOTEXTILE/SOD STRUCTURE IS CAUSING FLOODING.

MAINTENANCE WOULD CONSIST OF REMOVING OF SEDIMENTS WITH A STIFF

BRISTLE BROOM OR SQUARE POINT SHOVEL. IF INLET FILTER IS BEYOND THIS LEVEL

OF REPAIR, IT MAY BE NECESSARY TO REPLACE BOTH THE SOD AND GEOTEXTILE

FILTER.

9. IF SOIL EROSION/SEDIMENT CONTROL MEASURES ARE INADEQUATE FOR THE SITE.

THE PROPER EROSION CONTROL AUTHORITY MUST BE NOTIFIED.
