1. ALL EROSION AND SEDIMENTATION CONTROL DEVICES SHALL
BE CHECKED FOR STABILITY AND OPERATION FOLLOWING
EVERY RUNOFF -PRODUCING RAINFALL EVENT AND IN NO
CASE LESS THAN ONCE EVERY WEEK. ANY NEEDED
REPAIRS WILL BE MADE IMMEDIATELY TO MAINTAIN ALL
DEVICES IN THE OPERATING CONDITIONS INTENDED.
2. ALL AREAS WILL BE SEEDED, FERTILIZED, AND RESEEDED
AS NECESSARY AND MULCHED ACCORDING TO
SPECIFICATIONS IN THE VEGETATION PLAN IN ORDER TO
ESTABLISH AND MAINTAIN A VIGOROUS, DENSE VEGETATIVE
COVER.
3. ANY SEDIMENT TRACKED ONTO THE ADJACENT PUBLIC
ROAD SHALL BE REMOVED ON A DAILY BASIS.
4. SEDIMENT SHALL BE REMOVED FROM BEHIND SILT FENCING
& CHECK DAMS WHEN THE SEDIMENT ACCUMULATES TO
A DEPTH OF SIX INCHES.

VEGETATIVE SEEDING
AFTER COMPLETION OF GRADING ACTIVITIES AND THE
CONSTRUCTION OF SWALES, ALL EXPOSED AREAS SHALL
BE SEEDED TO THE FOLLOWING SPECIFICATIONS:
SEED BED
LIME 1-1/2 TON PER ACRE
FERTILIZER 1/2-TON PER ACRE
SEED
RYE GRAIN 50 LBS PER ACRE
TALL FESCUE 100 LBS PER ACRE
MAY THROUGH AUGUST:
CENTIPEDE 5 LBS PER ACRE
PROCEDURE
STRAW MULCH SHALL BE APPLIED AT A RATE WHICH WILL
INSURE APPROXIMATELY 75% COVERAGE OF THE SEEDED
AREA. THE STRAW AND SOWN SEED WILL BE LIGHTLY
DISCED INTO THE BED TO GIVE IT FURTHER RESISTENCE
TO BLOWING AND WASHING.
THE CONTRACTOR SHALL GUARANTEE A FULL STAND OF
GRASS OVER THE ENTIRE DISTURBED AREA. IF NECESSARY
THE CONTRACTOR WILL WET DOWN THE AREAS TO ASSIST
IN SEED GERMINATION OR AID IN GROWTH IN TIMES OF
EXCESSIVELY DRY WEATHER. A STAND OF GRASS WILL BE
CONSIDERED ACCEPTABLE WHEN THE ENTIRE STAND OF
GRASS IS AT LEAST FOUR INCHES HIGH AND HAS
ACHIEVED AT LEAST 95% COVERAGE OF DISTURBED
AREAS. RESEEDING WILL BE REQUIRED AS NECESSARY BY
THE CONTRACTOR TO OBTAIN THE SPECIFIED STAND OF GRASS,
NOTE:
THE ANGLE FOR GRADED SLOPES AND FILL SHALL BE NO GREATER
THAN THE ANGLE THAT CAN BE RETAINED BY VEGETATIVE COVER
OTHER ADEQUATE EROSION CONTROL DEVICES OR STRUCTURES. IN
ANY EVENT, SLOPES LEFT EXPOSED WILL, WITHIN 21 CALENDAR DAYS
OF COMPLETION OF ANY PHASE OF GRADING, BE PLANTED OR
OTHERWISE PROVIDED WITH TEMPORARY OR PERMANENT GROUND
COVER, DEVICES, OR STRUCTURES SUFFICIENT TO RESTRAIN EROSION.
