III. REQUIRED ITEMS CIIECKLIST
The following checklist outlines design requirements per the North Carolina Stormwater Best Management Practice
Manual and Administrative Code Section: 15A NCAC 2H .1000. These requirements are subject to change in
accordance with the manual and rules.
Initial in the space provided to indicate that the following design requirements have been znet and supporting
documentation is attached. If a requireme~zt Izas not been met, attach written. justification. An incomplete
submittal package will result in a request for additional information and will substantially delay final review and
approval of the project.
Applicant's Initials
LM a. System is located 50 feet from class SA waters and 30 feet froze other surface waters.
~M b. No vertical sand bed is proposed.
LM c. The bioretention area is at least 15 feet wide by 40 feet long.
LM d. A grass buffer strip and sheet flow conditions are provided at the inlet.
LM e. Seasonal High Water table depth is at least 2 feet below the planting elevation surface.
Uv( f. Ponding depth of 6-12" is provided.
LM g. In-situ soils have a minimum hydraulic conductivity of 0.52 inches per hour.
Lly~ h. An in-depth soils report is provided. (report should include soil types, boring log, map,
suitability for placement of the control system, seasonal high water table, infiltration rate, etc.)
LM i. The planting soil has a minimum hydraulic conductivity of 0.52 inches per hour. The type and
placement specifications of the planting media are noted on the plans.
l-M j. The planting soil meets minimum soil specifications per the latest version of the NCDENR
Stormwater Best Management Practices Manual, including a low phosphorus content to
promote phosphorus removal. (P-Index of 20 to 40 is optimal.) Include a soils test, indicating
P-Index, from a certified lab foz• those projects draining to Nutrient Sensitive Waters.
LEA k. System is designed to draw down the design storage volume to the proposed bottom elevation
under seasonal high water conditions within 24 hours. Draw down calculations are attached.
~M 1. A detailed planting plan, prepared by a qualified individual, is provided on the plans. This plan
shall indicate a variety of suitable species, location, spacing, soil preparation, fertilizer
requirements, installation procedures, construction schedule, etc..
SVJLJ-108 4.07
Page 2 of 4

~_ m. Type of mulch layer and depth is specified on the plans.
LOV) n. Plan and section details for the bioretention area are provided. (including dimensions and
elevations)
LM o. Plan details for the inlet and outlet structures are provided. (including dimensions and
elevations)
p. All side slopes stabilized with vegetated cover are no steeper than 3:1 (H:V).
Lim q. A benchmark is provided to determine the sediment accumulation in the basin area.
i.A~l r. Vegetated filter is provided for overflow and detail is shown on plans (Required minimum
length is 50 feet for SA waters, 30 feet for other waters).
~ ~ s. Runoff in excess of the design volume bypasses off-line systems (bypass detail provided).
~~ t. Plans ensure that the installed system will meet design specifications (constructed or restored)
upon initial operation once the project is complete and the entire drainage area is stabilized.
IV. BIORETENTION BA5IN OPERATION AND MAINTENANCE AGREEMENT
Records of maintenance items to include dates, inspector's name, type of maintenance, etc. shall be kept and made
available to Division staff upon request. Maintenance activities shall be performed as follows:
1. Inspect the bioretention area system for soil and mulch erosion, vegetated cover, and general condition after
every significant runoff producing rainfall event and at least monthly. Remove trash as needed.
2. Repair eroded areas immediately, re-seed, re-plant, and re-mulch as necessary to maintain good vegetative and
mulch cover.
Remove accumulated sediment as needed to maintain good infiltration. When the filtering capacity diminishes
substantially (e.g., when water ponds on the surface for more than 24 hours), the top few inches of material must
be removed and replaced with fresh planting soil material. Regardless of infiltration capacity, accumulated
sediment in the bioretention basin shall be removed when the depth is reduced to 75% of the original design
depth. The system shall be restored to the original design depth without over-excavating. Over-excavating may
cause the required water table separation to be reduced and may compromise the ability of the system to perform
as designed. Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a
manner that will adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream,
etc.).
4. Replace, or add additional mulch as needed. Removal of the old mulch layer before applying the new layer is
recommended every 2 to 3 years.
5. Prune trees and shrubs and remove debris on an annual basis. Grassed vegetation should not exceed 6 inches in
height.
6. Treat all diseased trees and shrubs whenever needed. Remove and replace all dead and diseased vegetation
considered beyond treatment every 6 months.
7. Replace support stakes yearly (in the spring). Replace deficient stakes or wires whenever needed

' ~ MAY-16-2001 11:55R FROM: TUCKER g ASSOCIATES 336-632-©207 T0: 8864458 P.2
8, Soil testing shall be conducted annually to determine pH and any accumulation of toxins in the planting media.
Lime or other alkaline substances shall be applied as recommended per the soil test and toxic soils shall be
removed, disposed of properly and replaced with new planking media.
9. All components of the bioretention area system shall be maintained in good working order.
10. If the Division determines that the system .is failing, the system will immediately be repaired to original design
specifications. If the system cannot be repaired to perform .its design function, other stormwater control devices
as allowed by NCAC 2H .1.000 must be designed, approved and constructed.
I aclu~owledge and agree by niy signature below that I am responsible for the performance of the ten maintenance
procedures listed above. I agree to notify DWQ of any problems with. the system or grior to any changes to the
system or responsible party.
