FROM THE PLANS
NOTES:
1. OOCELL #1 SHALL BE CONSTRUCTED AS A
TEMPORARY SEDIMENT BASIN DURING CONSTRUCTION.
2, THE GRADES SHOWN ARE THE FINAL GRADES FOR
THE BIOCELL, CONTRACTOR WILL NEED TO EXCAVATE
TO THE DEPTH INDICATED PER THE DETAIL.
3. PLANTING SOIL MATERIAL AND UNDERDRAIN SYSTEM
IS NOT TO BE PLACED UNTIL SITE HAS BEEN
COMPLETELY STABILIZED AND PAVED AREAS DRAINING
TO THE CELL ARE FLUSHED TO REMOVE LOOSE
SEDIMENT, AND APPROVAL HAS BEEN GRANTED BY AN
NCDENR INSPECTOR,
3. DURING THE TIME THAT THE BIOCELL IS A
TEMPORARY SEDIMENT BASIN, THE SKIMMER DRAIN WILL
BE ATTACHED TO THE EXISTING BASIN NEAR COLLEGE
ST. THIS BASIN IS TO BE REMOVED, AND A NEW CURB
INLET AND GRATED INLET ARE TO BE INSTALLED PER
SHEET C1.5, CONTRACTOR WILL NEED TO REINSTALL
PIPING FROM SKIMMER TO GRATED INLET #9 WHEN BASIN
AT THE ROAD IS REMOVED. SEE SHEET C1.4 INSET A
FOR SKIMMER DETAIL AND ATTACHED PIPEING. AFTER
CONNECTING TO BASIN #9, THIS PIPING WILL REMAIN
AND BE UTILIZED AS A PORTION OF THE UNDERDRAIN
SYSTEM. REMOVE SKIMMER AND INSTALL UNDERDRAIN
SYSTEM AS SHOWN.
FOOTING PER
WALL DESIGNER
INIEUIS
85-88% SAND
8-15X SILT -CLAY
3-5X ORGANIC MATTER
SOIL TEXTURE AND STRUCTURE
PLANTING SOILS FOR BIG -RETENTION AREAS ARE TO HAVE A SANDY LOAM,
SAND, OR LOAM TEXTURE. THESE SOILS HAVE A MAXIMUM CLAY CONTENT OF
1GR (SOILS WITH INFILTRATION RATES GREATER THAN 0.5 IN/HR ARE
SUITABLE FOR BIO-RETENTION). SANDY LOAM, LOAMY SAND, AND LOAM
SOILS HAVE MINIMUM INFILTRATION RATES RANGING FROM 0.52 TO ZO
IN/HR. SEE PLANTING SOIL REQUIREMENTS ABOVE,
S III ACIDITY
THE DESIRED SOIL PH WOULD LIE BETWEEN 5.5 AND 7.0. THE SOIL ACIDITY -
AFFECTS THE ABILITY OF THE SOIL TO ABSORB AND DESORB NUTRIENTS,
AND ALSO AFFECTS THE MICROBIOLOGICAL ACTIVITY IN THE Solt_
SOIL PLACEMENT
PLACEMENT OF SOIL IN BIO-RETENTION AREA SHOULD BE IN LIFTS OF
1-2 FEET AND LIGHTLY COMPACTED. MINIMAL COMPACTION
EFFORT CAN BE APPLIED TO THE SOIL BY TAMPING WITH A BUCKET
FROM A DOZER OR BACKHOE.
MULCH LAYER
THE MULCH LAYER SERVES TO PREVENT EROSION AND TO PROTECT THE
SOIL FROM EXCESSIVE DRYING. BIO-RETENTION AREAS ARE TO BE MULCHED
ONCE TREES AND SHRUBS HAVE BEEN PLANTED. MULCH TO BE HARDWOOD
AGED 12 MONTHS MINIMUM. MULCH TO BE FREE OF WEEDS, SOIL ROOTS,
OR ANY OTHER SUBSTANCE NOT CONSISTING OF EITHER BRANCE WOOD,
OR BARK. MULCH TO BE SPREAD APPROXIMATELY 3 INCHES IN DEPTH,
BUT NO MORE THAN 3 INCHES DEEP. GRASS BIOCELLS DO NOT REQUIRE MULCH
NOTES:
1, THE ENGINEER'S CERTIFICATION OF COMPLETION WILL BE REQUIRED PRIOR
TO FINAL PLAT OR CERTIFICATE OF OCCUPANCY. THE STORMWATER
CONTROL IS TO BE INSPECTED TO ENSURE IT IS FUNCTIONING AS DESIGNED
AND HAS FULL DESIGN VOLUME PRIOR TO ISSUANCE OF ANY CERTIFICATE
OF OCCUPANCY.

3-5X ORGANIC MATTER
SOIL TEXTURE AND STRUCTURE
PLANTING SOILS FOR BIO-RETENTION AREAS ARE TO HAVE A SANDY LOAM,
SAND, OR LOAM TEXTURE. THESE SOILS HAVE A MAXIMUM CLAY CONTENT OF
1OX (SOILS WITH INFILTRATION RATES GREATER THAN 0.5 IN/HR ARE
SUITABLE FOR 19I0-RETENTION). SANDY LOAM, LOA14Y SAND, AND LOAM
SOILS HAVE MINIMUM INFILTRATION RATES RANGING FROM 0.52 TO 2.41
IN/HR. SEE PLANTING SOIL REQUIREMENTS ABOVE.
SOiL ACIDITY
IMF: DESIRED SOIL PH WOULD LIE BE7u..EEN 5.5 AND 7.0. THE SOIL ACIDITY
AFFECTS THE ABILITY OF THE SOIL TO ABSORB AND DESORB NUTRIENTS.
AND ALSO AFFECTS THE MICROBIOLOGICAL ACTIVITY IN THE SOIL.
PLACEMENT OF SOIL IN 010-RETENTION AREA SHOULD BE IN LIFTS OF
1-2 FEET AND LIGHTLY COMPACTED. MIPIMAL COMPACTION
EFFORT CAN BE APPLIED TO THE SOIL BY TAMPING WITH A BUCKET
FROM A DOZER OR BACKHOE.
MULCH LAYER
THE MULCH LAYER SERVES TO PREVENT EROSION AND TO PROTECT THE
SOIL FROM EXCESSIVE DRYING. 010-RETENTION AREAS ARE TO BE MULCHED
ONCE TREES AND SHRUBS HAVE BEEN PLANTED. MULCH TO BE HARDWOOD
AGED 12 MONTHS MINIMUM. MULCH TO BE FREE OF WEEDS, SOIL ROOTS,
OR ANY OTHER SUBSTANCE NOT CONSISTING OF EITHER BRANCE WOOD,
OR BARK. MULCH TO BE SPREAD APPROXIMATELY 3 INCHES IN DEPTH,
BUT NO MORE THAN 3 INCHES DEEP. GRASS SIOCELLS DO NOT REQUIRE MULCH
NOTES:
1. THE ENGINEER'S CERTIFICATION OF COMPLETION WILL BE REQUIRED PRIOR
TO FINAL PLAT OR CERTIFICATE OF OCCUPANCY. THE STORMWATER
CONTROL iS TO BE INSPECTED TO ENSURE IT IS FUNCTIONING AS DESIGNED
AND HAS FULL DESIGN VOLUME PRIOR TO ISSUANCE OF ANY CERTIFICATE
OF OCCUPANCY.
