EROSION CONTROL:
1. ANY GRADING BEYOND THE DENUDED LIMITS SHOWN ON THE PLAN IS A
VIOLATION AND IS SUBJECT TO A FINE.
2. STABILIZATION IS THE BEST FORM OF EROSION CONTROL. TEMPORARY
SEEDING IS NECESSARY TO ACHIEVE EROSION CONTROL ON LARGE
DENUDED AREAS AND ESPECIALLY WHEN SPECIFICALLY REQUIRED AS PART
OF THE CONSTRUCTION SEQUENCE SHOWN ON THE PLAN. ALL GRADING
SLOPES MUST BE SEEDED AND MULCHED WITHIN 21 CALENDAR DAYS OF
COMPLETION OF GRADING. ALL FLAT AREAS ARE TO BE SEEDED AND
MULCHED WITHIN 21 WORKING DAYS.
3. ADDITIONAL DEVICES MAY BE REQUIRED AS AGREED UPON BY FIELD
INSPECTOR, ENGINEER, AND OWNER.
4. IF ACTIVE CONSTRUCTION CEASES IN ANY SLOPED AREA FOR MORE THAN 21
CALENDAR DAYS OR 21 WORKING DAYS IN FLAT AREAS, ALL DISTURBED
AREAS MUST BE SEEDED, MULCHED, AND TACKED, UNLESS WRITTEN
APPROVAL IS GRANTED BY THE EROSION CONTROL INSPECTOR.
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 LE S A THAN ONCE EVERY WEEK. ANY NEEDED REPAIRS
WILL BE MADE IMMEDIATELY TO MAINTAIN ALL PRACTICES AS DESIGNED.
2. SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN IT
BECOMES ABOUT 0.5 FEET DEEP. THE SEDIMENT FENCE WILL BE REPAIRED
AS NECESSARY TO MAINTAIN A BARRIER.
3. 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.
SEEDING SPECIFICATIONS:
LIME: APPLY 100 POUNDS PER 1,000 SQUARE FEET
FERTILIZER: APPLY 20 POUNDS 8-8-8 PER 1,000 SQUARE FEET

MULCH: APPLY 1-1/2 TONS/ACRE WHEAT STRAW (OR APPROVED EQUAL)
ON ALL SEEDED AREAS,
TACK: ALL SLOPES WITH STRAW MULCH EXCEEDING 3:1 TO HAVE
ASPHALT TACK APPLIED AT THE RATI_ OF 225 GALLONS/ACRE.
* AFTER SOIL PREPARATION AND SEEDING, INSTALL JUTE MATTING.
OR EQUAL ON ALL DISTURBED AREAS.
*MAINTAIN SEEDED AREAS UNTIL MINIMUM GROWTH IS ESTABLISHED
AND/OR FOR CONTRACT TIME.
