MULCHING
IMMEDIATELY AFTER SEED AREA SOWN, MULCH THE ENTIRE AREA EVENLY WITH
A LAYER OF WHEAT STRAW TO PROTECT AREA FROM EROSION. MULCH TO BE
APPLIED AT A RATE OF 75-100 LBS. PER 1000 SQUARE FEET.
SECURING MULCH:
THE MULCH SHALL BE HELD IN PLACE BY EMULSIFIED ASPHALT BINDER ON
SLOPES 2 TO 1 OR STEEPER, OR AS REQUIRED. APPLY ASPHALT AT 0.10
GALLON PER SQUARE YARD. IN HEAVY TRAFFIC AREAS, USE TYPE "RS" OR
"CRS" TO MINIMIZE REMOVAL OF TACK COAT. SYNTHETIC BINDERS MAY BE
USED AS RECOMMENDED BY THE MANUFACTURER TO ANCHOR THE MULCH.
TEMPORARY CHANNEL LININGS IF REQUIRED SHALL BE INSTALLED IN AREAS AS
SHOWN ON PLANS, OR AS REQUIRED TO PREVENT EROSION. LININGS AREA TO
BE LEFT IN PLACE THROUGHOUT PERMANENT SEEDING PROCEDURE.
MAINTENANCE
I. TEMPORARY SEEDING:
RESEED AND MULCH AREAS WHERE SEEDLING EMERGENCE IS POOR, OR
WHERE EROSION OCCURS, AS SOON AS POSSIBLE. DO NOT MOW.
PROTECT FROM TRAFFIC AS MUCH AS POSSIBLE.
II. PERMANENT SEEDING:
GENERALLY, A STAND OF VEGETATION CANNOT BE DETERMINED TO BE
FULLY ESTABLISHED UNTIL SOIL COVER HAS BEEN MAINTAINED FOR ONE
FULL YEAR FROM PLANTING. INSPECT SEEDED AREAS FOR FAILURE AND
MAKE NECESSARY REPAIRS AND RESEEDINGS WITHIN THE SAME SEASON, IF
POSSIBLE.
RESEEDING --IF A STAND HAS INADEQUATE COVER, RE-EVALUATE CHOICE
OF PLANT MATERIALS AND QUANTITIES OF LIME AND FERTILIZER.
RE-ESTABLISH THE STAND AFTER SEEDBED PREPARATION OR OVER -SEED
THE STAND. CONSIDER SEEDING TEMPORARY, ANNUAL SPECIES IF THE
TIME OF YEAR IS NOT APPROPRIATE FOR PERMANENT SEEDING.

NOTE: Pursuant to G.S. 113A-57(2), the angle for graded slopes and fills
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 14 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. Pursuant to G.S.
113A-57(3), provisions for permanent ground cover sufficient to restrain
erosion must be accomplished for all disturbed areas within 14 working days
or 90 calendar days (whichever is shorter) following completion of construction
or development.
VEGETATION MANTAINANCE:
IF A STAND HAS INADEQUATE COVER, RE-EVALUATE CHOICE OF PLANT
MATERIALS AND QUANTITIES OF LIME AND FERTILIZER. RE-ESTABLISH THE
STAND AFTER SEEDBED PREPARATION OR OVER -SEED THE STAND. CONSIDER
