SEEDBED PREPARATION
THE CONTRACTOR SHALL CUT AND DISPOSE OF WEEDS OR OTHER UNACCEPTABLE GROWTH ON THE AREAS
TO BE SEEDED, UNEVEN OR ROUGH AREAS SHALL BE SHAPED AND SMOOTHED TO PROVIDE FOR EFFECTIVE
SEEDING AND EASE OF MOWING. THE SOIL SHALL BE SCARIFIED TO A DEPTH OF NOT LESS THAN 5 INCHES.
CLODS SHALL BE BROKEN AND THE TOP 3-4 INCHES OF THE SOIL SHALL BE WORKED INTO A SEEDBED BY
THE USE OF PULVERIZERS, DRAGS, OR HARROWS. THE PREPARATION OF SEEDBEDS SHALL NOT BE DONE WHEN
THE SOIL IS FROZEN OR EXTREMELY WET,
LIMESTONE, FERTILIZER, AND SEED
LIMESTONE, FERTILIZER, AND SEED SHALL BE APPLIED WITHIN 24 HOURS AFTER COMPLETION OF SEEDBED
PREPARATION. LIMESTONE AND FERTILIZER MAY BE APPLIED AS PART OF THE SEEDBED PREPARATION, PROVIDED
IT IS WORKED INTO THE SOIL. IF NOT SO APPLIED, LIMESTONE AND FERTILIZER SHALL BE DISTRIBUTED UNIFORMLY
OVER THE PREPARED SEEDBED AT THE SPECIFIED RATE OF APPLICATION AND THEN HARROWED, RAKED, OR
OTHERWISE THOROUGHLY WORKED INTO THE SEEDBED, SEED SHALL BE DISTRIBUTED UNIFORMLY OVER THE
SEEDBED AT THE RATE OF APPLICATION SPECIFIED, AND IMMEDIATELY HARROWED, RAKED, OR DRAGGED AS
TO COVER THE SEED WITH A LAYER OF SOIL.
MULCHING
ALL SEEDED AREAS SHALL BE MULCHED. GRAIN STRAW MAY BE USED AS MULCH AT ANY TIME OF THE
YEAR. MULCH SHALL BE APPLIED WITHIN 24 HOURS AFTER THE COMPLETION OF SEEDING. CARE SHALL
BE TAKEN AS TO PREVENT DISPLACEMENT OF SOIL OR SEED FROM THE SEEDBED AREA DURING MULCHING
OPERATIONS. MULCH SHALL BE UNIFORMLY SPREAD BY HAND OR MECHANICAL SPREADER. AN ACCEPTABLE
APPLICATION WILL BE THAT WHICH WILL ALLOW SOME SUNLIGHT TO PENETRATE AND AIR TO CIRCULATE BUT
ALSO PARTIALLY SHADE THE GROUND, REDUCE EROSION AND CONSERVE SOIL MOISTURE.
MAINTENANCE
AREAS WHERE SEEDING AND MULCHING HAVE BEEN PERFORMED SHALL BE MAINTAINED IN SATISFACTORY
CONDITION UNTIL ACCEPTANCE OF THE PROJECT BY THE OWNER. AREA OF DAMAGE OR FAILURE DUE TO ANY
CAUSE SHALL BE REPAIRED OR REDONE AS NECESSARY.
SEEDING &MULCHING
A. NCDOT #5 OR #57 WASHED STONE SHALL BE USED. PAD TO BE 50' X 20' X 6" DEPTH MIN.
B. TURNING RADIUS SUFFICIENT TO ACCOMODATE LARGE TRUCKS TO BE PROVIDED.
C. ENTRANCE(S) SHALL BE LOCATED TO PROVIDE FOR MAXIMUM UTILITY BY ALL CONSTRUCTION VEHICLES.
D. PAD MUST BE MAINTAINED IN A CONDITION WHICH WILL PREVENT TRACKING OR DIRECT FLOW OF MUD
ONTO STREETS. PERIODIC TOPDRESSING WITH STONE WILL BE NECESSARY.
" CURB E. ANY MATERIAL WHICH IS TRACKED ONTO ADJACENT ROAD SHALL BE REMOVED IMMEDIATELY.
