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 met and supposing documentation is attached. If a requirement has not been met, attach written justification.

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. X 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 for those projects draining to Nutrient Sensitive Waters. x 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. X 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..

BIORETENTION BASIN 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. 3. 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.

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. 3. 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.

REQUIRED ITEMS CHECKLIST 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 met and supporting documentation is attached. If a requirement has 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 X a. System is located 50 feet from class SA waters and 30 feet from other surface waters. X b. No vertical sand bed is proposed. X c. The bioretention area is at least 15 feet wide by 40 feet long. N/A d. A grass buffer strip and sheet flow conditions are provided at the inlet. Parking lot bioretention basin. X e. Seasonal High Water table depth is at least 2 feet below the planting elevation surface. X f. Ponding depth of 6-12" is provided. No g. In -situ soils have a minimum hydraulic conductivity of 0.52 inches per hour. Undercut needed. Field inspector to field verify. X It. 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.) X 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. X 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 for those projects draining to Nutrient Sensitive Waters. X 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. X 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.. SWU-108 4.07 Page 2 of 4 x m. Type of mulch layer and depth is specified on the plans. ,BUG ^ 5 2009 x BY' n.

(including dimensions and elevations) x p. All side slopes stabilized with vegetated cover are no steeper than 3:1 (H:V). X q. A benchmark is provided to determine the sediment accumulation in the basin area.ViSual evidence of sediment has been indicated as the limit of sediment accumulation. N/A 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). Runoff discharges into an overflow structure and storm sewer. X s. Runoff in excess of the design volume bypasses off-line systems (bypass detail provided). X 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 BASIN 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: I. 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. 3. 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. SWU-108 4.07 Page 3 of 4 RECEIVED AUG 8. Soil testing shall be conducted annually to determine pH and any ac �rlation of toxins in the lanting media. Lime or other alkaline substances shall be applied as recommended �er le Is shall be removed, disposed of properly and replaced with new planting 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 .1000 must be designed, approved and constructed. I acknowledge and agree by my 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 prior to any changes to the system or responsible party.
