1.)THE CONTRACTOR SHALL CONTACT THE POWER CO., GAS CO., AND TELEPHONE CO. FOR THE EXACT
LOCATION OF ALL UNDERGROUND MAINS, CABLES, OR LINES BEFORE CONSTRUCTION BEGINS.
EXISTING UTILITIES SHOWN ON THESE PLANS ARE TAKEN FROM VARIOUS SOURCES AND THE
CONTRACTOR SHALL SATISFY HIMSELF OF THE ACCURACY.
2.)PIPE SEPARATION: THE FOLLOWING MINIMUM PIPE SEPARATION WILL BE MAINTAINED: 24 INCHES
VERTICAL SEPARATION BETWEEN CROSSING OF SANITARY SEWER AND STORM SEWERS, 18 INCHES
VERTICAL SEPARATION BETWEEN CROSSING OF SEWER (INCLUDING FORCE MAINS) AND WATER
MAINS, AND 10 FEET HORIZONTAL SEPARATION BETWEEN SANITARY SEWER (INCLUDING FORCE
MAINS) AND WATER MAINS. IF THESE SEPARATIONS CANNOT BE MAINTAINED, DUCTILE IRON PIPE
WILL BE USED 10 FEET EITHER SIDE OF CROSSING AND ALONG ENTIRE LENGTH OF LINE LESS THAN
10 HORIZONTAL FEET FROM WATER MAINS. WHENEVER A WATER MAIN CROSSES UNDER A SEWER
LINE BOTH LINES SHALL BE DUCTILE IRON PIPE 10 FEET EACH SIDE OF CROSSING. THE CONTRACTOR
SHALL RECEIVE APPROVAL FROM THE ENGINEER IN THE FIELD BEFORE PAYMENT WILL BE MADE AT
DUCTILE IRON PRICES.
3.)THE RIGHT-OF-WAY OR SHOWN TEMPORARY CONSTRUCTION EASEMENT SHALL DICTATE THE
LIMITS OF CONSTRUCTION.
4.)THE CONTRACTOR SHALL BE RESPONSIBLE FOR THE COORDINATION OF THE ADJUSTMENT OF
EXISTING UTILITIES, INCLUDING POWER POLES.
5.)THE CONTRACTOR SHALL REMOVE AND REPLACE ANY EXISTING CULVERTS AND HEADWALLS, AS
REQUIRED FOR THE CONSTRUCTION OF THE PROJECT.
6.)IF EXISTING STORMWATER CONVEYANCE STRUCTURES (i.e., CULVERTS & SEWERS) ARE DISTURBED
OR BREACHED IN ANY WAY, ADDITIONAL SEDIMENT CONTROL MEASURES MUST BE TAKEN TO
PREVENT SEDIMENT -LADEN RUNOFF FROM LEAVING THE CONSTRUCTION AREA.
iafyxtlI�IRii?
1.)NO POTABLE WATER OR WASTEWATER FACILITIES ARE PROPOSED FOR THIS PROJECT. RAW
(UNTREATED) WATER WILL BE AVAILABLE ONCE THE CONTRACTOR MAKES TAP IN ACCORDANCE WITH
PLANS, ALTHOUGH AVAILABLE PRESSURES MAY FLUCTUATE..

CONSTRUCTION SPECIFICATION
MATERIALS:
1. USE A SYNTHETIC FILTER FABRIC OF
AT LEAST 95% BY WEIGHT OF
POLYOLEFINS OR POLYESTER, WHICH IS
CERTIFIED BY THE MANUFACTURER OR
SUPPLIER AS CONFORMING TO THE
REQUIREMENTS IN ASTM D 6461.
SYNTHETIC FILTER FABRIC SHOULD
CONTAIN ULTRAVIOLET RAY INHIBITORS
AND STABILIZERS TO PROVIDE A
MINIMUM OF 6 MONTHS OF EXPECTED
USABLE CONSTRUCTION LIFE AT A
TEMPERATURE RANGE OF 0 TO 120' F.
2. INSURE THAT POSTS FOR SEDIMENT
FENCES ARE 1.33 LB/LINEAR FT STEEL
WITH A MINIMUM LENGTH OF 5 FEET.
MAKE SURE THAT STEEL POSTS HAVE
PROJECTIONS TO FACILITATE
FASTENING THE FABRIC.
3. FOR REINFORCEMENT OF STANDARD
STRENGTH FILTER FABRIC, USE WIRE
FENCE WITH A MINIMUM 14 GAUGE AND
A MAXIMUM MESH SPACING OF 6
INCHES.

1. OBTAIN EROSION CONTROL PERMIT AND ALL OTHER APPLICABLE PERMITS PRIOR TO ANY
LAND DISTURBING ACTIVITY.
2. SCHEDULE A PRE -CONSTRUCTION CONFERENCE WITH THE OWNER, ALL CONTRACTORS
FOR LAND DISTURBANCE AND/OR EROSION CONTROL AND EROSION CONTROL AUTHORITY
PERSONNEL TO DISCUSS THE PROJECT AND THE EROSION CONTROL PLAN.
3. INSTALL CONSTRUCTION ENTRANCE AND SILT FENCE AT THE LOCATIONS SHOWN ON THE
CLEARING AND GRUBBING EROSION CONTROL PLANS. ALL EROSION AND SEDIMENTATION
CONTROL MEASURES SHALL BE INSTATED PRIOR TO ANY LAND DISTURBING ACTIVITY. THE
MEASURES SHALL REMAIN IN PLACE UNTIL CONSTRUCTION OF THE PHASE IS NO LONGER
POSSIBLE WITHOUT REMOVAL OF THE MEASURES AND ALL POSSIBLE EARTHWORK IS
STABILIZED AROUND THE PHASE SUCH AS ROADWAY, GRASSED AREAS, ETC.
4. CONSTRUCT INFILTRATION BASINS AND SWALES FOR USE AS SEDIMENT COLLECTION
DEVICES DURING CONSTRUCTION.
5, BEGIN CLEARING AND GRUBBING OPERATIONS
5. MAINTAIN EROSION CONTROL DEVICES PER SPECIFICATIONS AND AFTER EVERY RUNOFF
PRODUCING RAINFALL.
6. AT COMPLETION OF CONSTRUCTION OR ANY PHASE OF GRADING, ESTABLISH VEGETATION
IN COMPLIANCE WITH NCDENR EROSION CONTROL REGULATIONS AND THESE PLANS.
7. REMOVE ALL TEMPORARY MEASURES, CLEAN OUT THE INFILTRATION BASINS OF ANY
ACCUMULATED SEDIMENT AND AFTER SITE IS PERMANENTLY STABILIZED CONSTRUCT FINAL
INFILTRATION BASINS AS SHOWN ON THE RESPECTIVE DETAIL.
NOTES
PURSUANT TO G.S. 133-A57(2), THE ANGLE FOR GRADED SLOPES AND FILLS SHALL BE
NO GREATER THAN THE ANGLE THAT CAN BE RETANEO 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.
PURSUANT TO G.S. 113A-57(3), PROVISIONS FOR PERMANENT GROUNDCOVER SUFFICIENT
TO RESTRAIN EROSION MUST BE ACCOMPLISHED FOR ALL DISTURBED AREAS WITHIN 15
WORKING DAYS OR 90 CALENDAR DAYS (WHICHEVER IS SHORTER) FOLLOWING COMPLETION
OF CONSTRUCTION OR DEVELOPMENT.
