Form SWU-103 Rev 3.99 Page 2 of 3 [V. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT 1. After every runoff producing rainfall event and at ]east monthly inspect the infiltration system for erosion, trash accumulation, vegetative cover, and general condition. 2. Repair eroded areas immediately, re-seed as necessary to maintain adequate vegetative cover, mow vegetated cover to maintain a maximum height of six inches, and remove trash as needed. 3. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow structures for blockage and deterioration. Remove any blockage and repair the structure to approved design specifications. 4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth in the pretreatment unit is reduced to 7~% 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.). A benchmark shall be established in the pretreatment unit. 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 give an accurate depth reading and not readily penetrate into accumulated sediments. «hen the design depth reads 0.90 feet in the pretreatment unit, the sediment shall be removed from both the pretreatment unit and the infiltration basin. ~. 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 desi_n function, other stormv<~ater 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 five 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.

The property is the location of the currently operating Pointe Marina. The subject property is currently developed with asingle-family residential dwelling, asphalt parking areas, and a marina office/dockhouse. The existing marina consists of wooden dock structures. The existing docking system is not proposed to be altered under this project. Previous CAMA Major Permit Applications have been submitted and approved associated with bulkhead replacement and marina renovations. (CAMA Permits Attached) The project permit packages are associated with upland development that w•il] occur on the property to construct the condominium units. It is proposed that t~~ elve residential condominium units be constructed on the 2.86 acre parcel. Paved access drives and parking areas will be extended into the project off of Old Lupton Road. The existing marina dockhouse will be demolished and a new dockhouse will be constructed on an existing concrete slab as sho~t~n on the project plans. As small manmade basin located on land to be o~~ned by Pamlico Consort. LLC and 1~1r. Joseph C..Avolis and :~1r. John Kevin Aeolis will be filled to accommodate the proposed development. The proposed condominium development will be ser<~ed by public water service provided by Pamlico County. Individual septic tank systems will be constructed to serve the proposed development. The sewage disposal areas are located remotely from the subject property near the corner of Old Lupton Road and Whortsonsville Road, approximately 1,800 feet northeast of the subject property. Sewage effluent will be pumped from the subject property to these off-site disposal areas. Permits have been issued for these remote disposal facilities by the Pamlico County Health Department. The following permits are being secured associated with the upland development portion of the proposed project: CAMA Major Permit 2. Coastal Stormwater Permit 3. Erosion and Sedimentation Control Permit 4. Public Water Permit 5. On-Site Wastewater Permit 6. NCDOT Driveway Permit 7. NCDOT Encroachment Agreement 8. Preconstruction Notification (PCN) 9. 401 Water Quality Certification 10. Neuse Riparian Buffer Variance All permitting efforts associated with the renovations of the existing marina facilities are being completed independently of the permit packages for the upland development. Find below a general description of the proposed development as it relates to each of these permits. A. CAMA >\lajor Permit A CA:v1A Major permit is being sought in order to properly execute this project. CAMA Areas of Em~ironmental Concern (AEC) exist on the property. The limits of the 7~ foot AEC are delineated on the project plans. Limited development is proposed to occur within these CA:~1A AEC areas as a part of the proposed upland development. The proposed disturbance within the CA~1A AEC area as part of the upland development includes the installation of limited impermeable surfaces within the CAMA AEC area and the light filling and Grading in the AEC areas to establish finish grades. Additionally, a small man made basin will be filled as delineated on the project plans. The basin areas to be filled coy ers a total of-1,096 SF. A total of 4~ linear feet of bulkheading will be installed to retain the fill in the mouth of the manmade basin to be filled. The total 7~ foot CAMA AEC area on the subject property is 62,6?3 SF, 1.44 acres. It is proposed that a total of 4,83? square feet of impermeable surfaces be created within the 76 foot LAMA AEC. A total of 7.71 % of the 7~ foot LAMA AEC ~~~ill be covered with impermeable surfaces upon the completion of the proposed upland development. The total area to be disturbed by the proposed development in the CAMA AEC is approximately 23,500 square feet. A 90 linear feet section of vinyl bulkheading is proposed to be placed in the section of shoreline in the area the existing dockhouse to be demolished. A six foot wide walkway is proposed to be constructed along the existing slip on Coffee Creek. Otherwise, no other land disturbing activities or construction are proposed to occur within the CAMA AEC. B. Coastal Stormwater Permit The subject property is located adjacent to Broad Creek, Browns Creek and Coffee Creek. Each of these creeks has a surface water classification of SA, HQW, NSW. Stormwater runoff from the project will discharge to these surface waters. Since the receiving surface waters are classified SA, an infiltration type system is required to comply with the Coastal Stormwater Regulations. The subject property covers a total area of 2.86 acres of land. It is proposed that a total of 0.89 acres of impermeable surfaces be created associated with upland development for the project. The overall built-upon density of the project is 3l .0% necessitating a High Density Stormwater permit. Since the receiving waters for this project are classified S,A, an infiltration type system is required. All stormw•ater runoff from the 1'/-inch storm will be routed to one of two infiltration basins designed for the pro~~'. F~:=°~~ -~-:_ .`:-,,~ upland development will bypass above the 1 ~= inch design volume will bypass the infiltration systems and will discharge to a vegetated s~t~ale along Old Lupton Road and ultimately to the marsh areas adjacent to Broad Creek. A total of (?)drainage basins are located on the subject property. One infiltration basin is proposed for each of these drainage basins. A discussion of the deg elopment in each drainage basin follows: Drainage Basin No. 1 covers a total area of i7.~"8 square feet. It is proposed that a total of ? 7,8-13 square feet of impermeable surfaces be created ~t ithin this drainage basin. The final built-upon percentage for this drainage basin is 3~.9°'0. Considering the impermeable and permeable surfaces within this drainage basin, the 1'/~-inch design storm volume ~~~as calculated to be 4,376 cubic feet. All runoff from Drainage Basin No. 1 discharges from the impermeable surfaces towards the entrance road. The entrance road will be constructed ~~~ith an im~erted crown and all runoff will discharge to Infiltration Basin No. 1 via one drop inlet. A weir structure is being provided in this drop inlet to divert all excess storm volume above the 1 `/ -inch storm volume to the vegetated Swale located along the western side of Old Lupton Road. Bypass Stormwater runoff will flow through a total of approximately 90 linear feet of vegetated Swale prior to entering a depressed basin area adjacent to the adjacent wetland area. Runoff at this location will accumulate and w'il] cap the back slope of the depressed area creating non-erosive flow prior to entering the ~0 foot Neuse Riparian Buffer area. At this point the discharge will flow across the vegetated 50 foot Neuse Riparian Buffer prior to entering the marsh area adjacent to Broad Creek. Infiltration Basin No. 1 is proposed to be constructed to contain a maximum design depth of 1.2 feet. The bottom of the infiltration basin will occur at elevation 3.8 or approximately''/z feet above the existing Grade in this area. The total calculated capacity of Infiltration Basin No. l is 4,71 1 cubic feet, which is greater than the 4,376 cubic foot design storm volume. Drainage Basin No. 2 is located on the eastern side of Old Lupton Road. This drainage basin covers a total area of 47,216 square feet. It is proposed that a total of 10,979 square feet of impermeable surfaces be created within this drainage basin. The built-upon percentage for this drainage basin is 23.3%. Considering the impermeable and permeable surfaces within this drainage basin, a 1'/-inch design storm volume was calculated to be 2,141 cubic feet. The runoff from the newly created impermeable surfaces within this drainage basin will be diverted to Infiltration Basin No. 2. All runoff will occur to a drer~ inlet which will be constructed ~~ ith an overflow weir to divert excess volume above the 1'/-inch design storm volume to the vegetated swales along Old Lupton Road. The bypass stormwater at tl;is location will accumulate with the bypass stormwater from Infiltration Basin No. 1 and ~t ill ultimately discharge in the same fashion as that occurring from Infiltration Basin No. 1. Infiltration Basin No. 2 will be constructed to a maximum depth of 1.0 feet. The calculated volume of Infiltration Basin No. 2 is 2.21 1 cubic feet. The capacity of this basin exceeds the 1'i -inch design storm volume of 2,141 cubic feet. A soils in~~esti«ation ~~~as completed on the subject property as a part of the initial design efforts. A series of hand augers ~~ere advanced on the subject property in the vicinity of the proposed infiltration basins. The soil profile encountered at each auner location can be described as follo~~s: DEPTH DESCRIPTIO\ U" - ~" Topsoil -1" - S" yledium Bro~~n Sande Loam S" - 1 S" Light Brost n 'Medium Sand 1 S" - 2S" Orange Sandy Clav ~t ith Tan l~iottles 2S" - 34" Grey Silty Sand 3-1" - 36" tiledium Brottn Silty Fine Sand The augers advanced in the area of Infiltration Basin No. 1 revealed soil wetness indicators at depths of approximately 18 inches below the surface. Groundwater was present at a depth of 28 inches at this location. Considering the elevations in this area of the site, soil wetness conditions were found to occur at an elevation of 1.7 feet. Groundwater «~as found to occur at an elevation of 0.87 feet. The bottom of Infiltration Basin No. 1 is proposed to occur at an elevation of 3.8 feet. A minimum of two feet of vertical separation between the bottom of the basin and the seasonal high water table is proposed. Hand augers advanced in the area of Infiltration Basin No. 2 revealed soil wetness indicators at a depth of approximately 28 inches below the surface with groundwater occurring at a depth of approximately 3~ inches below the surface. Considering the elevations in this area of the site, wetness conditions were found to occur at an elevation of 1.47 feet and groundwater ~~~as found to occur at an elevation of 0.88 feet. The bottom of Infiltration Basin No. 2 will occur at an elevation of 4.0 feet, or approximately 2.5 feet above the seasonal high water table in this area. Considering the sandy characteristics of the soils present on the subject property, a design permeability rate of 2.0 inches per hour vas selected as the design permeability rate for the project. Considering this rate, infiltration of the 1 !!-inch design stornl will occur within a time period of approximately 6 to 8 hours of a storm event. C. Erosion and Sedimentation Control Permit An Erosion and Sedimentation Control permit will be needed to properly execute the project since in excess of one acre of land ~~ ill be disturbed. It is proposed that all upland areas of the subject property other than areas ~~ithin the Zone 1 ~0 foot'~euse Riparian Buffer area and portions of the Zone 2 area be disturbed to execute the project. Additionally. it is proposed that the small inland basin present on the north~tiestern side of the subject propert}~ be filled. These are the only activities that ~~~ill occur belo~~~ the normal eater 1e~el on the subject propem. In addition to the onsite activities, land disturbing arti~ hies ~~ ill occur along the ri«ht-of- ~tav area of Old Lupton Road and ~~ ithin the proposed remote se~~ a~Te disposal area located 1,S00 feet northeast of the subject propem along Florence Road. The areas of disturbance are presented on the project plans. The total proposed disturbed area for this project is ~.~6 acres. A pern~it fee in the amount of S X00 is included with the permit application. Erosion and Sedimentation Control devices will be utilized on the subject property to protect the abutting surface waters and surrounding properties. Permanent vegetation will be established on the site in order to stabilize the finish surfaces. D. Pubic «'ater Supply Permit A Public Water Supply permit will be sought to properly execute the project. An existing 6-inch «ater main is located adjacent to the property along Old Lupton Road. Connections will be made to this water main. ]t is proposed that 6-inch water mains be extended into the project area in order to provide individual «~ater services for each of the twelve condominium units and to replace the existing public water service to the marina facility. The existing water distribution system in this area is owned by Pamlico County. Project plans and specifications for the water distribution system will be submitted to the State of North Carolina through Pamlico County for approval. E. On-Site «'aste~r~ater Permit Sewa<__>e disposal for the project ~yill occur to remote se~ya~e disposal areas located approximately 1,800 feet northeast of the subject property along Florence Road. The Pamlico County Health Department has issued onsite septic pern~its for four 6-bedroom septic systems. A copy of the applicable permits are attached. It is proposed that a septic tank and pump basin be constructed adjacent to each cluster of three residential units. All sewage will flow to the septic tanks. Effluent ~yill discharge from the septic tanks to individual pump tanks, where the effluent will be pumped to the remote drain field areas. F. \CDOT Drive«~av Permit .qn NCDOT Drive~yay permit ~yill be secured for the project to make drive connections to Old Lupton Road. G. \CDOT Encroachment Agreement .an \CDOT Encroachment Agreement ~~ ill be secured for the project in order to install t}~e utility improvements presented on the project plans along? Old Lupton Road. H. Preconstruction \otification (PC\~) -~ PCti application term ~~~ill he sub~l;itted to the ~~.~..`,rr,~~~ Corr s of En~~ineers to secure appro~ al to till the small manmade basin depicted on the project plans. The same application ~t ill be submitted to the tiorth Carolina Di. ision of ~~~ater Quality in order to secure a ->-01 ~~'ater Quality Certification to }ill the inland basin. .additionally, a'~euse Riparian Buffer Variance will be sought ~~ith this same permit to construct a new marina club house on the e~istin~ concrete slab located partially in Zone 1 and Zone 2 of the Meuse Buffer. o~-a~3~ STORMWATER CALCULATIONS Pointe Marina Condominiums Old Lupton Road, NCSR 1326, Pamlico County, North Carolina Prepared for: Pamlico Consort, LLC P.O.
