NOTE:
THE PROJECT NPDES CONSTRUCTION PERMIT REQUIRES THAT EROSION CONTROL DEVICES AND STORM WATER OUTFALLS
BE INSPECTED WEEKLY AND WITHIN 24 HOURS OF A 1/2-INCH RAIN EVENT. IT SHALL BE THE RESPONSIBILITY OF THE
CONTRACTOR TO CONDUCT THESE INSPECTIONS AND MAINTAIN RECORDS UNTIL THE AREA HAS STABILIZED,
EVIDENT BY 95% VEGETATIVE GROWTH FOR AREAS RECEIVING SEEDING. TO FACILITATE RAINFALL MONITORING, A RAIN
GAUGE IS REQUIRED TO BE ONSITE. ONCE STABILIZATION HAS BEEN ACCOMPLISHED, INSPECTION RECORDS ARE
TO BE FORWARDED TO THE CONTRACTING OFFICER AND ALL TEMPORARY EROSION CONTROL MEASURES REMOVED. THE
CONTRACTOR IS RESPONSIBLE FOR MAINTAINING COMPLIANCE WITH ALL PERMITS AND PLANS ANY CHANGES
MUST BE APPROVED BY THE STATE PRIOR TO EXECUTION. A COPY OF THE EROSION AND SEDIMENTATION
CONTROL PLAN, LETTER OF APPROVAL AND NPDES CONSTRUCTION PERMIT MUST BE MAINTAINED BY THE CONTRACTOR
AT THE PROJECT SITE.

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.
SPECIAL SEEDING NOTE:
THE ANGLE FOR GRADED SLOPES AND FILL SHALL BE NO GREATER
THAN THE ANGLE THAT CAN BE RETAINED BY VEGETATIVE COVER OR
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.
ADDITIONALLY, WITHIN 15 WORKING DAYS OR 90 CALENDAR DAYS
FROM THE COMPLETION OF THE PROJECT (WHICHEVER IS SHORTER),
PERMANENT GROUND COVER SHALL BE ESTABLISHED.
