NOTATIONS PER
\ `\ ,� \ NOTE RELATIVE TO BASIN SERVING AS AN EROSION SIATL
CONTROL FEATURE:
During construction of the Storage Center, the stormwater
wet detention basin will serve as the final erosion control
feature for the project. The pond area shall be cleared and
CI `\ \ \ grubbed and the pond shall be constructed first, prior to
N, .9O `,\ \ clearing and grubbing the site. Positive drainage shall be
,` \\ maintained toward the pond as the remainder of the site is
, cleared and grubbed by means of a temporary diversion or
other method. Following construction of Storage Center
including the stabilization of all disturbed surfaces with
adequate vegetative cover, the collected sediment within the
pond shall be removed and the pond restored to its design
grades.

2. SEE PLANS FOR ORIENTATION OF STORM DRAINS RELATIVE TO POND OUTLET.
3. ALL PIPE OUTLETS AND INLETS MUST BE SEALED WATER -TIGHT BETWEEN PIPE AND CATCH BASIN.
4, THE BASIN MAY BE DRAINED BY REMOVAL OF THE 4- PVC PLUG IN THE OUTLET STRUCTURE OR BY MEADS
OF A GAS POWERED MUD HOG TYPE PUMP.
CONSTRUCTION SEQUENCE
1. OBTAIN APPROVAL OF THE EROSION CONTROL PLAN FROM THE NORTH CAROLINA
DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES (NCDENR), LAND QUALITY
SECTION. OBTAIN APPROVAL OF THE STORMWATER PLAN FROM NCDENR, DIVISION OF
WATER QUALITY.
2. CLEAR AND GRUB THE STORMWATER POND AREA. CONSTRUCT THE STORMWATER
DETENTION BASIN.
3. INSTALL CONSTRUCTION ENTRANCE R TEMPORARY DIVERSIONS.
4. CLEAR AND GRUB THE REMAINDER OF THE SITE WHILE MAINTAINING POSITIVE
DRAINAGE TOWARD BASIN.
S. STRIP TOPSOIL AND STOCKPILE ON -SITE FOR USE IN FUTURE VEGETATED AREAS.
S. INSTALL BASIN OUTLET STRUCTURE.
7. INSTALL STORMWATER DRAINAGE SYSTEM, INCLUDING ALL PIPES, CATCH BASINtS
AND JUNCTION BOXES. INSTALL INLET PROTECTION AROUND CATCH BASINS.
B. FINISH GRADE DRIVES AND PARKING LOT.
9. PREPARE SUBGRADE, PLACE BASE MATERIAL, AND PAVE DRIVES AND PARKING LOT.
10. MAINTAIN ALL TEMPORARY EROSION CONTROL MEASURES UNTIL PERMANENT
GROUND COVER IS ESTABLISHED.
11. CHECK STORMWATER POND DEPTH FROM NORMAL POOL TO BOTTOM. IF IT IS
LESS THAN MINIMUM DESIGN DEPTH ALLOWED. EXCAVATE TO DESIGN DEPTH,
EROSION CONTROL GENERAL NOTES
1. ALL CONSTRUCTION ACTIVITIES SHALL BE PERFORMED IN COMPLIANCE WITH THE SEDIMENTATION POLLUTION CONTROL
ACT OF 1973,
2. ALL LAND DISTURBING ACTIVITIES ARE TO BE PLANNED AND CONDUCTED TO LIMIT EXPOSURE TO THE SHORTEST
FEASIBLE TIME.
3. ALL DISTURBED AREAS SHALL BE STABILIZED BY A PERMANENT GROUND COVER.
4. AS SOON AS ALL AREAS ARE PERMANENTLY STABILIZED, ALL PERMANENT MEASURES HAVE BEEN INSTALLED, AND FINAL
APPROVAL IS RECEIVED FROM THE LAND QUALITY SECTION, THE TEMPORARY MEASURES MAY BE REMOVED.
5. OVER THE LIFE OF THE PROJECT, THE OWNER SHALL MAKE PERIODIC INSPECTIONS TO EVALUATE THE SUCCESS IN
CONTROLLING EROSION OF SOILS TO OFF -SITE AREAS. IF AREAS ARE FOUND WHERE EROSION IS TAKING PLACE, THE
OWNER SHALL TAKE THE NECESSARY MEASURES TO REMEDY THE SITUATION,
6. MAINTAIN POSITIVE DRAINAGE FROM DISTURBED AREAS TOWARD DIVERSIONS.
SEEDING SCHEDULE
1. ALL DISTURBED AREAS DUE TO CONSTRUCTION AND ANY SEVERELY ERODED AREAS SHALL BE STABILIZED BY A
PERMANENT GRASS COVER. THE SEED SPECIES S1 1ALL BE SELECTED BASED ON THE TYPE SOIL PRESENT,
SEASONAL CONDITIONS AND OTHER CONSIDERATIONS. AS AN ALTERNATIVE, THE CONTRACTOR MAY USE THE METHODS
AND SCHEDULES SHOWN BELOW; HOWEVER, IT IS RECOMMENDED THAT A SPECIALIST BE CONSULTED WITH ATTENTION
