NOTES:
1. THE PLANTING SOIL SHALL HAVE A COMPOSITION BY VOLUME OF 85-88% WASHED SAND, 8-12%
FINES (SILT + CLAY), 3-5% ORGANIC MATTER.
2. SOIL SHALL BE UNIFORM COMPOSITION, FREE OF STONES, STUMPS, ROOTS OR SIMILAR OBJECTS
LARGER THAN ONE INCH, BRUSH, OR ANY OTHER MATERIAL OR SUBSTANCE WHICH MAY BE HARMFUL
TO PLANT GROWTH, OR A HINDRANCE TO PLANTING OR MAINTENANCE OPERATIONS. PLANTING SOIL
SHALL BE TESTED AND MEET THE FOLLOWING CRITERIA:
pH RANGE: 5.5-6.5
ORGANIC MATTER: 1.5-3.0%
MAGNESIUM (Mg): 35 LBS/ACRE
PHOSPHORUS (P-INDEX):10 TO 30
POTASSIUM (K20): 85 LBS/ACRE
SOLUBLE SALTS: NOT TO EXCEED 500 PPM
THE FOLLOWING TESTING FREQUENCIES SHALL APPLY TO THE ABOVE SOIL CONSTITUENTS:
PH, ORGANIC MATTER: 1 TEST PER 90 CUBIC YARDS
Mg, P205, K20, SOLUBLE SALTS: 1 TEST PER 500 CUBIC YARDS. BUT NO
LESS THAN 1 TEST PER BORROW SOURCE
ONE GRAIN SIZE ANALYSIS SHALL BE PERFORMED PER 90 CUBIC YARDS
OF PLANTING SOIL
3. PLACEMENT OF SOIL IN THE BIORETENTION AREA SHOULD BE IN LIFTS OF 18
INCHES OR LESS AND LIGHTLY COMPACTED. MINIMAL COMPACTION EFFORT CAN
BE APPLIED TO THE SOIL BY TAMPING WITH A BUCKET FROM A DOZER OR
BACKHOE.
4. THE CONTRACTOR SHALL PROVIDE THE ENGINEER, NCDEQ, AND THE CITY OF LEXINGTON THE RESULTS
OF A SOIL PERMEABILITY TEST OF THE PLACED SOIL. THE PERMEABILITY SHALL BE 1-2 IN/HR.
5. THE CITY SHALL HAVE RIGHT TO ACCESS THE PROPERTY FOR THE PURPOSE ON INSPECTIONS OF
THE BIO-RETENTION CELL. MAINTENANCE OF THE CELL SHALL BE THE RESPONSIBILITY OF THE

DEFINITION
SEEDING DISTURBED AREAS WITH PERENNIAL GRASSES AND (OR) LEGUMES TO PROVIDE A
PERMANENT VEGETATIVE COVER TO LESSEN RUNOFF AND SOIL EROSION.
PURPOSE
TO LESSEN SOIL EROSION AND PERMANENTLY STABILE DISTURBED AREAS CREATED BY
ORATING OF CONSTRUCTION SITES
CONDITIONS WHERE PRACTICE APPLIES
ALL BARE SOIL AREAS ON CONSTRUCTION SITES WHICH ARE NOT COVERED BY STRUCTURES
OR OTHER EROSION CONTROL DEVICES
PREPARATION
PREPARE SEEDBED BY SPREADING 3 - 6 INCHES OF TOPSOIL OVER AREA TO BE SEEDED.
REMOVE ALL STONES, BOULDERS, STUMPS OR DEBRIS FROM THE SURFACE WHICH WOULD
PROHIBIT GERMINATION OR PLANT GROWTH.
INCORPORATE INTO THE SOIL 800 TO 1,000 POUNDS OF 10-10-10 FERTILIZER PLUS 500
POUNDS OF TWENTY PERCENT (20%) SUPERPHOSPHATE PER ACRE AND TWO TONS OF
DOLOMITIC LIME PER ACRE UNLESS SOIL TESTS INDICATE THAT A LOWER RATE OF LIME
CAN BE USED.
