CONSTRUCTION NARRATIVE
THE PURPOSE FOR THIS PROJECT IS TO CONSTRUCT A NEW MEDICAL'' CARE FACILITY LOCATED IN
CITY OF ROCKINGHAM, RICHMOND COUNTY, NORTH CAROLINA. THE PROJECT SITE IS LOCATED
NORTH OF US HWY 74 BYPASS IN ROCKINGHAM. ACCESS TO THE SITE IS OFF MALLARD LANE.
THE FACILITY IS TO BE BUILT IN MULTIPLE PHASES. AT THE ON -SET OF CONSTRUCTION INITIAL
EROSION AND SEDIMENT CONTROL DEVICES ARE TO BE INSTALLED. AS CONSTRUCTION PROGRESSES
REMAINING EROSION AND SEDIMENT CONTROL DEVICES ARE TO BE INSTALLED. DURING THE ENTIRE
CONSTRUCTION PROCESS ALL DEVICES ARE TO BE PROPERLY MAINTAINED TILL FINAL STABILIZATION
HAS BEEN ACCOMPLISHED AND APPROVAL HAS BEEN AUTHORIZED BY THE SEDIMENTATION AND
EROSION CONTROL INSPECTOR. ONCE THE AUTHORIZATION HAS BEEN GIVEN TO REMOVE THE
SKIMMER BASINS CONSTRUCTION OF THE STORMWATER WETLANDS ARE TO BE CONSTRUCTED.

SYM. I DESCRIPTION
CONSTRUCTION SPECIFICATIONS:
ENSURE THAT THE SUBGRADE FOR THE FILTER AND RIPRAP FOLLOWS
THE REQUIRED LINES AND GRADES AS SHOWN IN THE PLANS. COMPACT
ANY FILL REQUIRED IN THE SUBGRADE TO THE DENSITY OF THE
SURROUNDING UNDISTURBED MATERIAL. LOW AREAS IN THE SUBGRADE
ON UNDISTURBED SOIL MAY ALSO BE FILLED BY INCREASING THE
RIPRAP THICKNESS.
THE RIPRAP AND GRAVEL FILTER MUST CONFORM TO THE SPECIFIED
GRADING LIMITS SHOWN ON THE PLANS.
FILTER CLOTH, WHEN USED, MUST MEET DESIGN REQUIREMENTS AND
BE PROPERLY PROTECTED FROM PUNCHING OR TEARING DURING
INSTALLATION. REPAIR ANY DAMAGE BY REMOVING THE RIPRAP AND
PLACING ANOTHER PIECE OF FILTER CLOTH OVER THE DAMAGED AREA.
ALL CONNECTING JOINTS SHOULD OVERLAP SO THE TOP LAYER IS
ABOVE THE DOWNSTREAM LAYER A MINIMUM OF 1 FOOT. IF THE
DAMAGE IS EXTENSIVE, REPLACE THE ENTIRE FILTER CLOTH.
RIPRAP MAY BE PLACED BY EQUIPMENT, BUT TAKE CARE TO AVOID
DAMAGING THE FILTER.
THE MINIMUM THICKNESS OF THE RIPRAP SHOULD BE 1.5 TIMES THE
MAXIMUM STONE DIAMETER.
RIPRAP MAY BE FIELD STONE OR ROUGH QUARRY STONE. IT SHOULD
BE HARD, ANGULAR, HIGHLY WEATHER - RESISTANT AND WELL GRADED.
CONSTRUCT THE APRON ON ZERO GRADE WITH NO OVERFILL AT THE
END. MAKE THE TOP OF THE RIPRAP AT THE DOWNSTREAM END LEVEL
WITH THE RECEIVING AREA OR SLIGHTLY BELOW IT.
ENSURE THAT THE APRON IS PROPERLY ALIGNED WITH THE RECEIVING
STREAM AND PREFERABLY STRAIGHT THROUGHOUT IT LENGTH. IF A
CURVE IS NEEDED TO FIT SITE CONDITIONS, PLACE IT IN THE UPPER
SECTION OF THE APRON.
IMMEDIATELY AFTER CONSTRUCTION, STABILIZE ALL DISTURBED AREAS
WITH VEGETATION.

MATERIAL TO THE DESIGNATED DISPOSAL AREA. PLACE TEMPORARY SEDIMENT CONTROL
MEASURES BELOW BASIN AS NEEDED.
2. ENSURE THAT FILL MATERIAL FOR THE EMBANKMENT IS FREE OF ROOTS, WOODY
VEGETATION, ORGANIC MATTER, AND OTHER OBJECTIONABLE MATERIAL. PLACE THE FILL
IN LIFTS NOT TO EXCEED 9 INCHES, AND MACHINE COMPACT IT. OVER FILL THE
EMBANKMENT 6 INCHES TO ALLOW FOR SETTLEMENT.
3. SHAPE THE BASIN TO THE SPECIFIED DIMENSIONS. PREVENT THE SKIMMING DEVICE
FROM SETTLING INTO THE MUD BY EXCAVATING A SHALLOW PIT UNDER THE SKIMMER OR
PROVIDING A LOW SUPPORT UNDER THE SKIMMER OF STONE OR TIMBER.
4. PLACE THE BARREL (TYPICALLY 4 —INCH SCHEDULE 40 PVC PIPE) ON A FIRM, SMOOTH
FOUNDATION OF IMPERVIOUS SOIL. DO NOT USE PREVIOUS MATERIAL SUCH AS SAND,
GRAVEL, OR CRUSHED STONE AS A BACK FILL AROUND THE PIPE. PLACE THE FILL

ATTACH A ROPE TO THE SKIMMER AND ANCHOR IT TO THE SIDE OF THE BASIN. THIS WILL
BE USED TO PULL THE SKIMMER TO THE SIDE FOR MAINTENANCE.
7. EARTHEN SPILLWAYS — INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST
EXTENT POSSIBLE. THE ACHIEVEMENT OF PLANNED ELEVATIONS, GRADE, DESIGN WIDTH,
r0� o
•
' Sys LA
AND ENTRANCE AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCCESSFUL OPERATION
D
OF THE SPILLWAY. THE SPILLWAY SHOULD BE LINED WITH THE LAMINATED PLASTIC OR
z
IMPERMEABLE GEO TEXTILE FABRIC. THE FABRIC MUST BE WIDE AND LONG ENOUGH TO
COVER THE BOTTOM AND SIDES AND EXTEND ONTO THE TOP OF THE DAM FOR
Zy��i._.
ANCHORING IN A TRENCH. THE EDGES MAY BE SECURED WITH 8 —INCH STAPLES OR PINS.
THE FABRIC MUST BE LONG ENOUGH TO EXTEND DOWN THE SLOPE AND EXIT ONTO
STABLE GROUND. THE WIDTH OF THE FABRIC MUST BE ONE PIECE, NOT JOINED OR
z
SPLICED; OTHERWISE WATER CAN GET UNDER THE FABRIC. IF THE LENGTH OF THE FABRIC
IS INSUFFICIENT FOR THE ENTIRE LENGTH OF THE SPILLWAY, MULTIPLE SECTIONS,
SPANNING THE COMPLETE WIDTH, MAY BE USED. THE UPPER SECTIONS SHOULD OVERLAP
THE LOWER SECTIONS SO THAT WATER CANNOT FLOW UNDER THE FABRIC. SECURE THE
0
UPPER EDGE AND SIDES OF THE FABRIC IN A TRENCH WITH STAPLES OR PINS. (ADAPTED
U
FROM " A MANUAL FOR DESIGNING, INSTALLING AND MAINTAINING SKIMMER SEDIMENT
BASINS." FEBRUARY 1999 J.W. FAIR CLOTH & SON.)

8. INLETS — DISCHARGE WATER INTO THE BASIN IN A MANNER TO PREVENT EROSION. USE
TEMPORARY SLOPE DRAINS OR DIVERSIONS WITH OUTLET PROTECTION TO DIVERT SEDIMENT
INFL(
LADEN WATER TO THE UPPER END OF THE POOL AREA TO IMPROVE BASIN TRAP
STRU
EFFICIENCY (REFERENCES: RUNOFF CONTROL MEASURES AND OUTLET PROTECTION).
9. EROSION CONTROL — CONSTRUCT THE STRUCTURE SO THAT THE DISTURBED AREA IS
MINIMIZED. DIVERT SURFACE WATER AWAY FROM BARE AREAS. COMPLETE THE EMBANKMENT
BEFORE THE AREA IS CLEARED. STABILIZE THE EMERGENCY SPILLWAY EMBANKMENT AND
ALL OTHER DISTURBED AREAS ABOVE THE CREST OF THE PRINCIPAL SPILLWAY IMMEDIATELY
AFTER CONSTRUCTION ( REFERENCES: SURFACE STABILIZATION).
10. INSTALL POROUS BAFFLES AS SPECIFIED IN PRACTICE 6.65
11. AFTER ALL THE SEDIMENT — PRODUCING AREAS HAVE BEEN PERMANENTLY STABILIZED,
AVEF
WIDT
REMOVE THE STRUCTURE AND AIL THE UNSTABLE SEDIMENT. SMOOTH THE AREA TO BLEND
WITH THE ADJOINING AREAS AND STABILIZE PROPERLY ( REFERENCES: SURFACE
STABILIZATION).
* AR
TOP
MAINTENANCE:
INSPECT SKIMMER SEDIMENT BASINS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT
RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE SEDIMENT AND RESTORE THE BASIN TO
ITS ORIGINAL DIMENSIONS WHEN SEDIMENT ACCUMULATES TO ONE —HALF THE HEIGHT OF
THE BATTLE. PULL THE SKIMMER TO ONE SIDE SO THAT THE SEDIMENT UNDERNEATH IT
CAN BE EXCAVATED. EXCAVATE THE SEDIMENT FROM THE ENTIRE BASIN, NOT JUST
AROUND THE SKIMMER OR THE FIRST CELL. MAKE SURE VEGETATION GROWING IN THE
BOTTOM OF THE BASIN DOES NOT HOLD DOWN THE SKIMMER.
REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE— ANCHOR THE BAFFLES IF WATER IS
FLOWING UNDERNEATH OR AROUND THEM.
IF THE SKIMMER IS CLOGGED WITH TRASH AND THERE IS WATER IN THE BASIN, USUALLY
JERKING ON THE ROPE WILL MAKE THE SKIMMER BOB UP AND DOWN AND DISLODGE THE
DEBRIS AND RESTORE FLOW. IF THIS DOES NOT WORK, PULL THE SKIMMER OVER TO THE
SIDE AND REMOVE DEBRIS. ALSO CHECK THE ORIFICE INSIDE THE SKIMMER FOR DEBRIS.
IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND
THE OBSTRUCTION CLEARED WITH A PLUMBER'S SNAKE OR BY FLUSHING WITH WATER. BE
SURE AND REPLACE THE ORIFICE BEFORE REPOSITIONING THE SKIMMER.

NOTE:
ALL SEDIMENT DEPOSITED IN THE STORMWATER DEVICES DURING CONSTRUCTION
MUST BE REMOVED, EROSION FEATURES MUST BE REPAIRED, AND THE VEGETATED
AREAS MUST BE RESTORED BEFORE OPERATION AS A STORMWATER BMP BEGINS.
NOTE:
THE CONTRACTOR SHALL ENSURE THAT THE STORMWATER
DEVICE HAS A MAXIMUM INFILTRATION OF 0.01 IN /HR.
THIS MAY BE ACCOMPLISHED BY RE- DISTRIBUTING
EXISTING CLAYS OR USING BORROW CLAY AS NECESSARY
AS DIRECTED BY THE GEOTECHNICAL ENGINEER.
THE CONTRACTOR SHALL HAVE A NC LICENSED
GEOTECHNICAL ENGINEER VERIFY A MAXIMUM OF 0.01
IN /HR INFILTRATION PRIOR TO CONVERTING THE
EXCAVATED AREA FROM A SEDIMENT BASIN TO A
PERMANENT STORMWATER DEVICE. IF 0.01 IN /HR
MAXIMUM INFILTRATION CANNOT BE MAINTAINED A
PERMANENT LINER WILL NEED TO BE INSTALLED. IF
A LINER IS USED, THE SOIL MUST BE TESTED FOR
INFILTRATION RATE PRIOR TO INSTALLATION BY A NC
LICENSED GEOTECHNICAL ENGINEER. THE LINER SHALL
BE INSTALLED SUCH THAT FINAL GRADES SHOWN
WILL REMAIN THE SAME.
