1. INSTALL TEMPORARY GRAVEL CONSTRUCTION ENTRANCE PADS. (SEE DETAIL)
2. INSTALL EROSION CONTROL DEVICES AT SITE DISCHARGE POINTS TO PREVENT
OFF SITE SEDIMENTATION.
3. CONSTRUCT DETENTION POND. EXCAVATION SHALL BE COMPLETE PRIOR TO
INSTALLATION OF OUTFLOW STRUCTURE.
4. INSTALL THE REMAINING SEDIMENT AND EROSION CONTROL PROTECTION.
S. INSTALL THE STONE BASE AND ASPHALT FOR THE PROPOSED PARKING.
6. PROVIDE A GROUNDCOVER (TEMPORARY OR PERMANENT) ON EXPOSED SLOPES
WITHIN 21 CALENDAR DAYS FOLLOWING COMPLETION OF ANY PHASE OF
GRADING; AND, A PERMANENT GROUNDCOVER FOR ALL DISTURBED AREAS
WITHIN 15 WORKING DAYS OR 90 CALENDAR DAYS (WHICHEVER IS SHORTER)
FOLLOWING COMPLETION OF CONSTRUCTION OR DEVELOPMENT
7. REMOVE SEDIMENT FROM DETENTION POND AND RESTORE TO DESIGN DEPTHS.
8. MONITOR AND MAINTAIN THE INSTALLED EROSION CONTROL MEASURES AND
REPAIR AS NECESSARY.
9. ONCE VEGETATION IS ESTABLISHED, REMOVE THE CONTROL DEVICES.
CONSTRUCTION SEQUENCING
CONSTRUCTION SPECIFICATIONS:
1. LAY ONE BLOCK ON EACH SIDE OF THE STRUCTURE
ON ITS SIDE IN THE BOTTOM ROW TO ALLOW POOL
DRAINAGE. THE BLOCK FOUNDATION SHOULD BE
EXCAVATED AT LEAST 2 INCHES BELOW THE CREST OF
THE STORM DRAIN. PLACE THE BOTTOM ROW OF BLOCKS
AGAINST THE EDGE OF THE STORM DRAIN FOR LATERAL
SUPPORT AND TO AVOID WASHOUTS WHEN OVERFLOW
OCCURS. IF NEEDED, GIVE LATERAL SUPPORT TO
SUBSEQUENT ROWS BY PLACING 2 X 4 WOOD STUDS
THROUGH BLOCK OPENINGS.
2. CAREFULLY FIT HARDWARE CLOTH OR COMPARABLE
WIRE MESH WITH 1/2-INCH OPENINGS OVER ALL BLOCK
OPENINGS TO HOLD GRAVEL IN PLACE.
3. USE CLEAN GRAVEL, 3/4- TO 1/2-INCH IN
DIAMETER, PLACED 2 INCHES BELOW THE TOP OF THE
BLOCK ON A 2:1 SLOPE OR FLATTER AND SMOOTH IT TO
AN EVEN GRADE. NCDOT #57 WASHED STONE IS
RECOMMENDED.

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.
SOIL AMENDMENTS
APPLY LIME AND FERTILIZER ACCORDING TO SOIL TESTS, OR APPLY 3,000-5,000 LB/ACRE GROUND
AGRICULTURAL LIMESTONE (USE THE LOWER RATE ON SANDY SOILS) AND 1,000 LB/ACRE 10-10-10 FERTILIZER.
MULCHING
APPLY 4.000 LB/ACRE GRAIN STRAW OR EQUIVALENT COVER OF ANOTHER SUITABLE MULCH. ANCHOR
STRAW BY TACKING WITH ASPHALT, NETTING, ROVING, OR BY CRIMPING WITH A MULCH ANCHORING TOOL.
A DISK WITH BLADES SET NEARLY STRAIGHT CAN BE USED AS A MULCHING TOOL.
MAINTENANCE
IF GROWTH IS LESS THAN FULLY ADEQUATE, REFERTILIZE IN THE SECOND YEAR, ACCORDING TO SOIL TESTS
OR TOPDRESS WITH 500 LB/ACRE 10-10-10 FERTILIZER. MOW AS NEEDED WHEN SERICEA IS OMITTED FROM
THE MIXTURE. RESEED, FERTILIZE, AND MULCH DAMAGED AREAS IMMEDIATELY.
SEEDING & MULCHING
THE CONTRACTOR SHALL COMPLY WITH ALL APPLICABLE REQUIRMENTS OF THE EROSION
AND SEDIMENT CONTROL STANDARDS AND SPECIFICATIONS OF THE DEPARTMENT OF NATURAL
RESOURCES AND COMMUNITY DEVELOPMENT. SOIL EROSION AND SEDIMENTATION CONTROL
MEASURES SHALL BE PROVIDED ON ALL AREAS OF THE SITE WHICH ARE DISTURBED OR
GRADED. CONTRACTOR SHALL PROVIDE GROUND COVERS (SEE SCHEDULE BELOW) WITHIN 30
CALENDAR DAYS AFTER COMPLETION OF CONSTRUCTION WITHIN THE SPECIFIC AREAS. THE
CONTROL MEASURES SHALL BEGIN PRIOR TO ANY LAND DISTURBING ACTIVITY INCLUDING
CLEARING; SHALL CONTINUE DURING THE CONSTRUCTION AND SHALL CONTINUE WITH THE
NECESSARY MAINTENANCE UNTIL THE DISTURBED LAND IS STABILIZED. COMPLIANCE WITH LOCAL
AND/OR STATE SOIL EROSION AND SEDIMENTATION CONTROL LAWS SHALL BE THE ENTIRE
RESPONSIBILITY OF THE CONTRACTOR. THIS PARAGRAPH IS INTENDED TO SERVE ONLY AS A
GUIDE TO THE CONTRACTOR FOR COMPLIANCE WITH SUCH LAWS. ORDERS, RULES AND
REGULATIONS CONCERNING EROSION AND SEDIMENTATION CONTROL PROTECTION OF EXISTING
STRUCTURES AND FACILITIES FROM SEDIMENTATION SHALL BE THE RESPONSIBILITY OF THE
CONTRACTOR. ITEMS TO BE PROTECTED SHALL INCLUDE, BUT ARE NOT LIMITED TO CATCH BASINS,
NATURAL WATERWAYS, DRAINAGE DITCHES, WALKS, DRIVES, ROADS, LAWNS, AND STREAMS.

PLANTING NOTES
1. VEGETATED SHELF SHALL BE PLANTED
WITH PLANTS SELECTED FROM THE TABLE
PROVIDED. 2 OR 3 PLANTS SHALL BE CHOSEN
FROM THE TABLE FOR EACH ZONE.
2. PLANT MATERIAL MAY BE AVAILABLE FROM
LOCAL WETLAND AREAS AND DITCHES. THE
CONTRACTOR SHALL VERIFY WITH THE LOCAL
OFFICE OF COASTAL AREA MANAGEMENT
WHETHER OR NOT A PERMIT IS REQUIRED TO
TAKE PLANTS FROM THESE AREAS.
3. APPROPRIATE TRANSPLANTING OR
PLANTING METHODS, INCLUDING SPACING AND
TIME OF YEAR, SHALL BE DETERMINED
ACCORDING TO PLANTS CHOSEN. (PRIOR TO
DIGGING, THE TOPS OF THE PLANTS SHOULD BE
CUT OFF TO A HEIGHT OF 4-6 INCHES. CUT OR
DIG PLUGS APPROX. 4 INCHES SQUARE MAKING
SURE TO GET FULL ROOT DEPTH. THIS PROCESS
SHOULD IMPROVE THE SURVIVAL RATE OF MOST
OF THE PLANTS.)
