As of now lots 1-57 are to have a BUA no greater than ,500 9qu e � feet. Lots 58-95 are to have a BUA no greater than 3,000 square 50C square feet was simply used to ensure stormwater ponds of conservative size. 2. Pond #6 does not require baffles. The pond satisfies the 3:1 lengt�l -to-width ratio requirement. Pond #6 has a required surface area of 5,364 square feet, O Id • which -would require a pond with dimensions of 43' x 129'. Pond #6 provides 7,858 square feet of surface area and has dimensions of roughly 6 Znn d #6 is oversized on both accounts, therefore baffles were decme ecessary. 7u A)92tem K cut-off trench with label has been added to the Pond #4 plan view %Pig on sheet SW-').

The current proposal is for phases IA and 1B consisting of approximately 80 acres. The intent of this project is to develop streets, drainage improvements, residential�-multi- mulnd amenities. This phase of the development will support 95 single family home sites andfamily units. The impervious coverage has been kept to a minimum to promote in filtration as much as possible. A master association is to be formed for Grayson Park and this association will maintain ownership and maintenance responsibilities for the amenity and stormwater ponds to be permitted. Existing Site: Site topography in the area is relatively flat with slopes typically less than (4) percent. The entire project follows the natural drainage pattern of northwest to southwest into surrounding wetlands. Vegetation consists primarily of grasses, minor ground cover and row pines. Subsurface soils on the site are primarily Wando Sands with some silty sands and organics. The soils are extremely well drained with high infiltration rates. Proposed Improvements: Improvements proposed include drainage devices, streets, and utilities. Drainage for the most part will sheet flow from the lots into the streets which will have curb and gutter to direct drainage to low points in the roads. Drainage from the low points will drain into stormwater ponds that drain to surrounding wetlands. The use of these stormwater ponds will also allow the project to conform to the new County stormwater regulations of pre -development and post -development runoff rates.

Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality The Wilmington Regional Office received a Stormwater Management Permit Application for Grayson Park - Phases 1A & 1 B on July 7, 2006. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Please provide a dimension for the driveways of the multi -family units. Some of the private drives appear to have an inverse crown. There is no cross-section that includes an inverse crown. Please add any appropriate roadway cross -sections and label them accordingly. The exact (plan view) location and dimensions of the cutoff trench and baffle walls are not clearly identified on the site plan. It will be difficult to provide this detail at 1 "=100' scale. It is recommended that this detail be provided at a better scale, perhaps on the details shown on sheet SW-3. The location and linear feet are needed for each cutoff trench and the length and approximate location within the basin is needed for each baffle wall. 4. The baffles must extend to the bottom of the permanent pool. 5. On the pond 1 section, there is a 3" pipe specified on the left of the cutoff trench and a 6" pipe specified on the right of the trench. 6. Please specify how the pond will be drained for maintenance or in an emergency. Typically a note specifying a pump is provided. 7. Please specify the forebay bottom elevation on all pond sections. 8. Please provide a cross-section of the "system K" outlet channel. It must have side - slopes no greater than 3:1. 9. The head of the "system K" outlet channel appears to be —50' from the nearest wetland. However, the outlet is significantly lower in elevation than the wetland. Please provide a calculation that the distance provided is sufficient to avoid a drawdown impact to the wetlands (typically a basic ellipse equation calculation is used to satisfy this concern) NotthCarolina 1Zaturally North Carolina Division of Water Quality 127 Cardinal Drive Extension Phone (910) 796-7215 Customer Service 1-977-623-6748 Wilmington Regional Office - Wilmington, NC 28405 Fax (910) 350-2004 Internet. ww,,.ncwatCmUallty.org An Equal Opportunity/Affirmative Action Employer - 50 % Recycledl10 % Post Consumer Paper yson Park July 19, 2006 Stormwater Permit # SW8 060238 10.

Please provide a detail of the outlet structure grate (or specify that the max trash guard opening is 4"). 12. Please call out the offsite drainage area on the offsite map. Please note that this request for additional information is in response to a partial, preliminary review. The requested information should be received by this Office prior to July 31, 2006, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If you need additional time to submit the information, please mail or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.

Wilmington, NC 28405 RE: Grayson Park— Phases I & I Stormwater Project No. SW8 060238 Dear Mr. Gordon: Per our meeting, please find the enclosed response to your request for additional information for the above referenced project. 1. Cut-off trenches have been added to ponds # 1, #4, #5 and #6 to keep the wetlands from draining back into those ponds. The details for the ponds have also been revised to show the cut-off trench. 2. Pond #6 is oversized. It has a surface area of 9,028 sf, but only 5,364 sf is required per the pond calculations. With a required surface area of 5,364.sf, the pond would need to be 42' by 128'to meet the 3:1 length to width ratio requirement. Pond #6 is roughly 88' by 134' which exceeds what is required. Therefore, baffles are not necessary for Pond #6. Ponds #4 has been revised to show a baffle in order to lengthen the flow distance from the flare end section to the outlet structure. The shape, size and location of Pond #5 have been revised. Calculations are included. 3. The bridges have been labeled as pervious structures. 4. The driveways in the multi -family sections have been added to the plans and their impervious areas added to the pond calculations. 5. The impervious areas for the pond spreadsheets have been revised and show how the impervious areas were determined. 151 Poole RoaA, Suite 100 • Belville, NC2,5451 • TEL: (910)353-1044 • FAX: (910)353-1045 www. ca pefearengineering. com 6. The temporary pool elevations on the wet detention basin supplements have been revised. 7. All infrastructure associated with the amenity area has been removed from the plans. 8. A sheet containing an aerial photo of the offsite buildings used to calculate the offsite impervious has been added to this package. 9. A sheet showing the dimensions of the permanent pool has been added to this package. 10. Spot elevations of the roadway high and low points have been added to the plans. 11. Roadway cross -sections have been revised. 12. Cul-de-sac details have been added. I trust this information to be sufficient for your review and approval.

Easley, Governor William G. Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality The Wilmington Regional Office received a Stormwater Management Permit Application for Grayson Park - Phases 1A & 1 B on February 27, 2006. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Please revisit the drawdown orifice configuration. a. The drawdown pipe sizes appear to be incorrect on sheet 2. b. The drawdown pipes are not drawn on the site plan. C. A 1 or 2" orifice through an outlet structure box is fine, but a long 1 or 2" pipe through the embankment is not permittable. This configuration will clog very easily. d. The permanent pool of each pond is well below the lowest contour elevation of the adjacent wetland. No outlet is provided. It does not appear the proposed system can draw down the storage volume to permanent pool. 2. Please provide a copy of the wetland jurisdictional determination map signed by the US Army Corps of Engineers. 3. Please provide documentation showing Mr. Sullivan is a member of Maco Road Partners, LLC. Only the Articles of Organization are filed with the Secretary of States office, and that document does not list the members of the LLC. The LLC's operating agreement has been submitted in the past to satisfy this requirement. 4. Please provide dimensions of the multi -family units. Typical Dimensions may be used where appropriate. Please also add a note indicating all roof runoff will be directed to the permitted stormwater system. 5. Please provide dimensions for all roadways. If using cross -sections, be sure to account for all variations (cul-de-sacs, traffic circle, hammerhead, entrance road etc...). It is not clear where each of the provided cross -sections apply. No sidewalks are shown on the cross -sections. 6. Please dimension the project boundary.

Please provide a copy of the draft proposed restrictive covenants for the project (that contain all required stormwater language). If this document is not available, just the proposed stormwater language may be submitted if it is signed, dated and notarized by the applicant. A copy of the required stormwater language for high -density subdivisions is enclosed. It is not clear what is proposed in the amenity area. The application lists buildings, streets, sidewalks & "other" proposed BUA (but no parking). There are no lots in the pond 5 DA; there not any buildings drawn either. There is parking drawn (though it appears to be partially turned off). Any BUA specified as buildings, streets etc on the application must be drawn & dimensioned on the site plan. If it is not proposed (to be permitted now), please remove it from the site plan (and label the area for "future development"). Please also clarify what the "other" BUA allocation is on the application. If it is the future allocation — please label it as such. 9. Please address the following issues with the configuration of ponds 4 & 5. a. Pond 4 utilizes a 7.5 ft depth to calculate the required surface area for the pond. Yet only a very small portion of the main bay meets this 7.5 ft depth. The majority of the pond surface area is forebay, which is much more shallow. Please reconfigure the forebay & bottom so that the 7.5ft depth is maintained for the majority of the flow path. If this is not feasible, use an average depth for the pond when calculating required surface area. b. It is not clear how the road is crossing pond #5. Is it a bridge? No portion of the pond (bottom) may be less than 3 ft. If it must be <3ft (for example where the pond crosses under the road), then that portion of the pond should be treated like a pipe and subtracted from the surface area and volume of the pond.. 10. Please provide spot elevations for high & low areas of the roadway. 11. Please address the following issues with the vegetated shelf of each pond. a. The detail refers to a 10' maintenance access shelf. This should be labeled as a vegetated shelf or an aquatic bench. It is below the permanent pool and is not intended for maintenance access. b. Please provide proposed aquatic vegetation for this vegetated shelf. C. The vegetated shelf,is drawn on the site plan around the entire main bay of each pond. The detail sheet specifies it around the entire pond. Either option is acceptable; please clarify. 12. The temporary pool or storage elevation corresponds to the invert elevation of the next highest outlet device above the permanent pool orifice (in this case the emergency spillway). All storage elevation/volumes listed on the supplement should reflect this elevation for each pond. 13. There appear to be several inlets that were not included on the storm drain schedule (CI 74-78). Also, if it is at all possible, please place the storm drain schedule on the site plan sheet — it will facilitate the review. Additional fees, not to exceed 50% of the original permit application fee, may be charged for subsequent reviews due to the insufficiency of a permit application, as specified by Section 11 AA of S.L. 2003-284. => Because the application has significant permitting issues/deficiencies, a resubmittal fee of $1,000 will be required in order for this project to remain in the express program. Please contact this office to schedule a resubmittal date. 'Grayson Park — Phases I & 1B March 7, 2006 Stormwater Permit # SW8 060238 Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to April 6, 2006, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If you need additional time to submit the information, please mail or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.

Gordon In accordance with Title 15 NCAC 2H.1000, the Coastal Stormwater Management Regulations, deed restrictions and protective covenants are required for High Density Residential Subdivisions where lots will be subdivided and sold and runoff will be treated in an engineered stormwater control facility. Deed restrictions and protective covenants are necessary to ensure that the development maintains a "built -upon" area consistent with the design criteria used to size the stormwater control facility. I, , acknowledge, affirm and agree by my signature below, that I will cause the following deed restrictions and covenants to be recorded prior to the sale of any lot: 1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number as issued by the Division of Water Quality under NCAC 2H.1000. 2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the stormwater management permit. 3. These covenants are to run with the land and be binding on all persons and parties claiming under them. 4. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Water Quality. 6. The maximum allowable built -upon area per lot is square feet. This allotted amount includes any built -upon area constructed within the lot property boundaries, and that portion of the right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does not include raised, open wood decking, or the water surface of swimming pools. T. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be accomplished through a variety of means including roof drain gutters which drain to the street, grading the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them into a component of the stormwater collection system. Lots that will naturally drain into the system are not required to provide these additional measures.

The entire project follows the natural drainage pattern of northwest to southwest into surrounding wetlands. Vegetation consists primarily of grasses, minor ground cover and row pines. Subsurface soils on the site are primarily Wando Sands with some silty sands and organics. The soils are extremely well drained with high infiltration rates_ Proposed Improvements: Improvements proposed include drainage devices, streets, and utilities. Drainage for the most part will sheet flow from the lots into the streets which will have curb and gutter to direct drainage to low points in the roads. Drainage from the low points will drain into stormwater ponds that drain to surrounding wetlands. All piped stormwater will employ flow spreaders and 30' vegetated buffers before entering wetlands. The use of these stormwater ponds will also allow the project to conform to the new County stormwater regulations of pre -development and post -development runoff rates. 01-19—tOD6 09:ZOam From—xerox +910 392 9327 T-442 P.005/011 F-979 LOCATION MAP SCALE = 1:2M Y CAPE Engineering, _ngin � 7 _\ : Stonnwater Project No. SW8051240 Subject: Re: Stormwater Project No. SW8051240 From: Linda Lewis <linda.lewis@ncmail.net> Date: Mon, 27 Feb 2006 08:27:13 -0500 To: Andrea Larkins<andrea.larkins@capefearengineering.com> CC: Beverly Rivenbark <Beverly.

The North Carolina Administrative Code requires any project that must receive either Sedimentation and Erosion Control Plan approval and/or a CAMA Major permit to apply for and receive a Stormwater Management Permit by the Division of Water Quality. Any construction on the subject site, prior to receipt of the required permit, will constitute a violation of 15A NCAC 21-1.1000 and may result in appropriate enforcement action by this Office. Either a Stormwater Permit Application Package including 2 sets of plans, completed application form, fee, and supporting documentation, or a written response regarding the status of this project and the expected submittal date must be received in this Office no later than March 16, 2006. Failure to respond to this request may result in the initiation of enforcement action, and construction may experience a subsequent delay. The NPDES 010000 Federal Stormwater Permit that accompanies the Erosion Control Plan approval letter must NOT be considered the Coastal Stormwater Management Permit, which will be signed by the Water Quality Supervisor. Please reference the Project Number above on all correspondence. If you have any questions, please call me at (910)-796-7215 or email me at linda.lewis@ncmail.net.
