BID -RETENTION SOIL MIXTURE:
Blo-retention Soil Mixture (BSM): shall be placed and graded using low ground -contact pressure equipment or by excavators and/or backhoes
operating on the ground adjacent to the bio-retention facility. No heavy equipment shall be used within the perimeter of the bio-retention
facility before, during, or after the placement of the BSM. The BSM shall be placed in horizontal layers not to exceed 12 inches for the
entire area of the bio-retention facility. The BSM shall be compacted by saturating the entire area of the bio-retention facility after each
lift of BSM is placed until water flows from the under -drain. Water for saturation shall be applied by spraying or sprinkling. An appropriate
sediment control device shall be used to treat any sediment -laden water discharged from the under -drain. If the BSM becomes
contaminated during the construction of the facility, the contaminated material shall be removed and replaced with uncontaminated material at
no additional cost to the Administration. Final grading of the BSM shall be performed after a 24-hour settling period. Final elevations shall
be within 2 inches of elevations shown on the Contract Plans.
The Bio-retention Soil Mixture (BSM) shall be a uniform mix, free of stones, stumps, roots or other similar objects larger than two inches.
No other materials or substances shall be mixed or dumped within the bio-retention area that may be harmful to plant growth, or prove a
hindrance to the planting or maintenance operations.
Prior to placing the under -drain and the BSM, the bottom of the excavation shall be roto-tilled to a minimum depth of 6 inches to alleviate
any compaction of the facility bottom. Any substitute method for roto-tilling must be approved by the Engineer prior to use. Any ponded
water shall be removed from the bottom of the facility and the soil shop be friable before roto-tilling.
Once the BSM has been placed the entire bio-retention area shall be sodded with grass that has been grown in sandy soils or that has the
roots washed clean of any clay or other materials that could clog the function of the bio-retention system.
OPERATION AND MAINTENANCE
North Carolina storm water rules require annual inspections by the regulating agency of bio-retention areas as a minimum. More frequent
inspections by the land owner or system operator are strongly encouraged to ensure the proper operation of bio-retention areas.
A. Rainfall Event
1. Inspect the basin after every runoff -producing rainfoll event.
B. Monthly Inspection
1. Inspect the basin monthly -
2. Check the bio-retention area side slopes; remove trash and repair eroded areas before the next rainfall event.
3. Check the vegetative and rock filters for sediment accumulation, erosion and proper operation of the flow spreader
mechanism and repair as necessary.
C. Quarterly P

basin grates and basin bottoms. Check piping or obstructions.
2. Check pond inlet pipes for undercutting, replace rip -rap and repair broken pipes.
3. Reseed grossed swoles, including the vegetated filter if applicable, twice a year as necessary. Repair eroded areas
immediately.
D. Six Month Inspection
1. Remove accumulated sediment from the bottom of the outlet structure or other areas where accumulated sediment is noted.
2. Inspect the embankment taking note of any wet areas where water may be seeping through the soil.
E. General Inspection
1. Maximum grass height is to be Bin.
2. No woody vegetation shall be allowed to grow in the bio-retention area.
3. Debris shall be removed from blocking the inlet and outlet structures and from areas of potential clogging.
4. Periodic removal of dead vegetation shall be accomplished.
5. All components of the bia-retention system must be kept in good working order.

�iTUNMWAI'Ett MANAUEMEN'1NUTE�:
1. THE DEVELOPER OR HIS AGENT SHALL CONTACT THE ENGINEER WHEN THE BEST
MANAGEMENT PRACTICE($) ARE CONSTRUCTED AND ABOUT TO BECOME
OPERATIONAL SO A FINAL INSPECTION CAN BE PERFORMED TO DETERMINE
COMPLIANCE WITH THE APPROVED PLAN CAN BE PERFORMED.
2. PRIOR TO CONSTRUCTION, A SOIL TEST OF THE BID -RETENTION FILTER MEDIA
SHALL BE REVIEWED AND APPROVED BY THE ENGINEER OF RECORD WITH A COPY
SENT TO THE ENGINEER. THE TEST SHALL CONSIST OF BOTH THE STANDARD SOIL
TEST FOR pH, PHOSPHORUS, MAGNESIUM, AND POTASSIUM AND ADDITIONAL TESTS
OF ORGANIC MATTER, AND SOLUBLE SALTS. ALL TESTING RESULTS SHALL COME
FROM THE SAME TESTING FACILITY. THE NC F DEPARTMENT
E 0 AGRICULTURE NCDA
LAB IS THE PREFERRED TESTING FACILITY. SHOUL
D THE pH FALL OUT OF THE
ACCEPTABLE RANGE, IT MAY BE MODIFIED (HIGHER) WITH LIME OR (LOWER) WITH
IRON SULFATE PLUS SULFUR OR AS DIRECTED BY THE NCDA OR ENGINEER
J. PRIOR TO CONSTRUCTION A COMPOSITION TEST OF THE BID -RETENTION FILTER
MEDIA SHALL BE REWEWED AND APPROVED BY THE ENGINEER OF RECORD WITH A
COPY SENT TO THE ENGINEER FILTER MEDIA SHALL CONFORM TO THE
FOLLOWING: 85-889 SAND (USDA TEXTURAL CLASSIFICATION), 8-12% FINES (SILT
AND CLAY), AND 3-58 ORGANIC MATTER (PEATMOSS OR PINE BARK) BY VOLUME
4. PERFORM A DOUBLE RING INFILTRATION TEST (MINIMUM OF 3 TESTS OR I PER
500 SF OF FILTER MEDIA WHICHEVER IS GREATER) AT THE COMPLETION OF THE
BID -RETENTION BMP. INFILTRATION RATE OF THE CONSTRUCTED BID -RETENTION
MEDIA SHALL BE BETWEEN 1-6 IN/HR. PROWDE A COPY OF THE RESULTS TO
THE ENGINEER.
5. ANNUAL MAINTENANCE INSPECTION AND REPORT REQUIRED - THE OWNER OF A
PERMITTED STRUCTURAL STORMWATER BMP/CONTROL SHALL ANNUALLY SUBMIT A
MAINTENANCE AND INSPECTION REPORT FOR EACH BMP TO THE STORMWATER
ADMINISTRATOR. ANNUAL INSPECTIONS SHALL BEGIN WITHIN ONE YEAR OF THE
RECORDATION OF ANY DEED(S) SHOWING STORMWATER BMPs/CONTROL
STRUCTURES.
6. UPON COMPLETION OF THE PROJECT, AND BEFORE A CERTIFICATE OF OCCUPANCY
SHALL BE GRANTED, THE ENGINEER OF RECORD SHALL CERTIFY THAT THE
COMPLETED PROJECT IS IN ACCORDANCE WITH THE APPROVED STORMWATER
MANAGEMENT PLANS AND DESIGNS,
Z A FINAL INSPECTION OF THE SITE AND STORMWATER MANAGEMENT BMP/CONTROLS
TO BE SCHEDULED WITH AND COMPLETED BY THE ENGINEER & INSPECTOR.
8. THE ENGINEERS CERTIFICATION OF COMPLETION WILL BE REQUIRED PRIOR TO THE
FINAL PUT OR CERTIFICATE OF OCCUPANCY THE STORMWATER CONTROL IS TO
BE INSPECTED TO ENSURE IT IS FUNCTIONING AS DESIGNED AND HAS FULL
