Remove accumulated sediment annually or when depth is reduced to 75-x of the original design depth. Restore depot to original design depth without over -excavating. Over -excavating may cause tine required water table separation to be reduced and may compromise the ability of the system to perform as designed_ The water level in any monitoring wells will be recorded after a 1 inc: rainfall event and at least once a month. Chronic high water table elevations (within l foot of the bottom of the system for a period of three months) shall be reported to DWQ immediately. 5. If DWQ determines that the system is failing, the system will immediately be repaired or replaced to original design specifications. If the system cannot be repaired to perform its design function, other stormw.ater control devices as allowed by NCAC 2H A000 must be designed, approved and constructed. 6. Remove accumulated sediment from the infiltration system annually or when depth in the unit 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 abiliry 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.). A benchmark shall be established in the infiltration system. The benclunark will document the original design depth so that accurate sediment accumulation readings can be taken. The measuring device used to determine the depth at the benchmark shall be such that it will gave an accurate depth reading and not readily penetrate into accumulated sediments. When the depth at the benchmark reads 2' , the accumulated sediment shall be removed from the system.

DEED RESTRICTIONS AND PROTECTIVE COVENANT'S The following italicized deed restrictions and protective covenants are required to be recorded for all subdivisions,-outparcels and future development prior to the We of any lot. If lot sizes vary significantly, a table listing each lot number, size and the allowable built -upon area for each lot must be provided as an attachment. 1. The following covenants are intended to ensure ongoing compliance with state stormwater management permit number as issued by the Division of Water Quality. These covenants may not be changed or deleted without the consenfZf the State. 2. No -more than square feet of any Iot shall be covered by structures or impervious materials. impervious materials include asphalt, gravel, concrete, brick, stone, slate or similar material but do not include wood decking or the water surface of swimming pools. 3. SwaIes shall not be fiIIed in, piped, or altered except as necessary to provide driveway crossings. a-. Built -upon area in excess of the permitted amount requires a state stormwater management permit modification prior to construction. 5. All permitted runoff from outparcels or future development shall be directed into the permitted stormwater control system. These connections to the stormwater control system shall be performed in a manner that maintains the integrity and performance of the system as permitted By your signature below, you certify that the recorded deed restrictions and protective covenants for this project shall include all the applicable items required above, that the covenants will be binding on all parties and persons Claiming under them, that they will run with the land, that the required covenants cannot be changed or deleted without concurrence from the State, and that they will be recorded prior to the sale of any lot.

UNDERGROUND LNU ILTRATION TRENCH OPERATION AND AGREEMENT 1. After every runoff producing rainfall event and at least monthly inspect the bypass/overflow structure for blockage and deterioration and the infiltration system for erosion, trash accurnuiation. grass cover _and general condition. 2 Repair eroded areas immediately, re -seed as necessary fo maintain adequate vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash and blockages as needed to maintain system performance. I R-rnove accumulated sediment annually or when depth is reduced to 75(7,o of the original design depth. Restore. depth to original design depth without over -excavating. Over-excavadn- may cause the required water table separation to be reduced and may compromise the ability of the system to perform as designed. 4, The water level in any monitoring wells will be recorded after a 1 inch rainfall event and at least once a month. Chronic high water table elevations (within 1 foot of the bottom of the system for a period of three months) shall be reported to DWQ immediately. 5. If DWQ determines that the system is failing, the system will immediately be repaired or replaced 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. 6. Remove accumulated sediment from the infiltradon system annually or when depth in the unit is reduced' to 75% of the originai 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 strearri, etc.). A benchmark shall be established in the infiltration system. The benchmark will document the original design depth so that accurate sediment accumulation readings can be taken. The measuring device used to determine the depth at the benchmark shall be such that it will g?ve an accurate depth reading and not readily penetrate into accumulated sediments. When the depth at the benchmarks reads 2' - the accumulated sediment shall be removed from the system.
