EROSION & SEDIMENT CONTROL PLAN for
f PLANNED EROSION CONTROL PRACTI CES\
CE TEMPORARY GRAVEL CONSTRUCTION ENTRANCE
SHALL BE INSTALLED AT 1HE ENTRANCES TO THE PROLECT
FROM AN DOSING ROADWAY. DRAINAGE SHOULD BE AWAY FROM
1HE ROAD AND EROSION WILL BE CONTROLLED WITH DOWNSTREAM
PRACTICES DURING WET WEATHER IT MAY BE NECESSARY TO WASH
TRUCK TIRES AT THESE LOCATIONS
LAND GRADING
GRADING SHOULD BE LIMITED TO AREAS AS SHOWN ON 1HE
PLANS CUT AND FILL SLOPES SHALL BE 3:1 OR FLATTER EXCEPT
WHERE SPEOFlCALLY INDICATED. CARE SHALL BE TAKEN DURING
LAND GRADING ACT1W1IES NOT TO DAMAGE EXISTING TREES THAT
ARE IDENIIFlED AS 'TO BE PRESERVED'.
SILT FENCE
SEDIMENT FENCING SHOULD BE INSTALLED AS SHOWN ON THE
PLAN, TO DELINEATE AND PROTECT WETLANDS AND SPE F7ED AREAS
AND AROUND ANY TEMPORARY STOOP/LE AREAS AS NECESSARY TO
PREVENT ANY GRADED INTERIOR AREAS FROM ERODING ONTO ADJACENT
LANDS OR ROADWAY, OR INTO INLETS OR AS DIRECTED BY ENGINEER
OR JOHNSTON COUNTY EROSION CONTROL PERSONNEL
CONSTRUCTION ROAD STABILIZATION
UPON REACHING F1NAL GRADE AND AFTER U17U11ES HAW
BEEN INSTALLED, ROADWAY/PARKING AREAS ARE TO BE
STABILIZED BY PLACING SUB -BASE AS SHOWN IN THE TYPICAL
STREET CROSS-SECTION DETAIL ON 1HE PLAN, TO REDUCE
EROSION AND DUST DURING THE REMAINDER OF CONSTRUCTION.
SEDIMENT BASIN
THE SEDIMENT BASIN IS TO BE CONSTRUCTED F1RST (SEE
CONSTRUCTION SCHEDULE AND IS THE PRIMARY PRACTICE TO
PREVENT SEDIMENT ROM LEAVING THE SIZE DETAILED DESIGN AND
SPILLWAY CONF1GURATIONS ARE SPE F1ED IN THE DETAIL SHEET.

WATER FROM THE BASINS WATER SURFACE THUS REMOVING THE HIGHEST
QUALTY WATER FOR DELIVERY TO 1HE UNCONTROLLED ENVIRONMENT.
A POROUS BARRIER INSTALLED INSIDE A TEMPORARY SEDIMENT TRAP,
SKIMMER BASIN OR SEDIMENT BASIN TO REDUCE THE VELOCITY AND
TURBULENCE OF WATER FLOWING THROUGH THE MEASURE AND TO FACILITATE
THE SETTLING OF SEDIMENT FROM WATER BEFORE DISCHARGE

LEMPO?ARY SEEDING
1. COMPLETE GRADING BEFORE PREPARING SEEDBEDS AND INSTALL ALL NECESSARY
EROSION CONTROL PRACTICES, SUCH AS DIKES WATERWAYS AND BASINS
2 MINIMIZE STEEP SLOPES BECAUSE THEY MAKE SEEDBED PREPARATION DIFFICULT
AND INCREASE THE EROSION HAZARD.
3. IF SOLS BECOME COMPACTED DURING GRADING, LOOSEN THEM TO A DEPTH OF
6-8 INCHES USING A RIPPER, HARROW, OR CHISEL PLOW. SEEDBED PREPARA 11ON
GOOD SEEDBED PREPARATION IS ESSENTIAL TO SUCCESSFUL PLANT
ESTABLISHMENT. A GOOD SEEDBED IS WELL -PULVERIZED, LOOSE AND UNIFORM.
WHERE HYDROSEEDING METHODS ARE USED, THE SURFACE MAY BE LEFT W11H A
MORE IRREGULAR SURFACE OF LARGE CLODS AND STONES.
4. LIMING - APPLY LIME ACCORDING TO SOIL TEST RECOMMENDATIONS IF THE PH
(ACIDITY) OF THE SOIL IS NOT KNOW, AN APPLICATION OF GROUND
AGRICULTURAL LIMESTONE AT THE RAZE OF 1 TO 1 1/2 TONS/ACRE ON
COARSE -TEXTURED SOILS AND 2-3 TONS/ACRES ON FINE -TEXTURED SOLS IS
USUALLY SULTICIENT. APPLY LIMESTONE UNIFORMLY AND INCORPORATE INTO THE
TOP 4-6 INCHES OF SOIL SOLS 1,11H A PH OF 6 OR HIGHER NEED NOT BE
LIMED.
5. FERTILIZER- BASE APPLICATION RAZES ON SOIL TESTS WHEN THESE ARE NOT
POSSIBLE APPLY A 10-10-10 GRADE FERTILIZER AT 700-L,000 LB./ACRE BOTH
FERTILIZER AND LIME SHOULD BE INCRPORAIED INTO THE TOP 4-6 INCHES O-
SOIL IF A HYDRAULIC SEEDER IS USED, DO NOT MIX SEED AND FERTILIZER MORE
THAN 30 MINUTES BEFORE APPLICATION.
6. SURFACE ROUGHENING- IF RECENT TILLAGE OPERATIONS HAW RESULTED IN A
LOOSE SURFACE ADDITIONAL ROUGHENING MAY NOT BE REQUIRED EXCEPT TO
BREAK UP LARGE CLODS IF RAINFALL CAUSES THE SURFACE TO BECOME SEALED
OR CRUSTED, LOOSEN IT JUST PRIOR TO SEEDING BY DISKING, RAKING HARROWING
OR OTHER SUITABLE METHODS GROOVE OR FURROW SLOPES STEEPER THAN 3:1
ON THE CONTOUR BEFORE SEEDING (PRACTICE 6:03, SURFACE ROUGHENING).
Z PLANT SELECTION SELECT AN APPROPRIATE SPECIES OR SPECIES MIXTURE FROM
TABLE 6.10A, FOR SEEDING IN LAZE WWN1ER AND EARLY SPRING, TABLE 610B FOR
SUMMER, AND TABLE 6.10C FOR FALL
8. SEEDING - EVENLY APPLY SEED USING A CYCLONE SEEDER (BROADCAST), DRILL,
