Wilmington, NC 28405 RE: Compass Pointe Temporary Drive & Commercial Center Request for Additional Information Response DWQ Stormwater Project Number: SW8 080107 Dear Mr. Pusey: Please find the enclosed response to your request for additional information for the above referenced project. Also note that there have been a few changes to the plan since the last submittal. Since the temporary sales center and gravel parking lot constitute a low density stormwater project. The wet detention basin previously submitted has been removed and the Stormwater runoff will now sheet flow away from the site. The other change to the plan is that the size of the gravel parking lot has been decreased and an additional dirt road through the site has been added. Due to these changes a new page 2 of the stormwater application and an updated low density supplement has been included in this submittal. As for your request for additional information please note these responses: 1. Spot elevations have been added to the plan in and around the parking lot for clarification of the stormwater flow path. 2. There is to be no curb around the parking lot at this time. The parking lot is being designed in a crown to sheet flow away in all directions. A cross section detail of the parking lot has been added to the plan. The entire site is now the drainage area and no area of the project is of such high density that it threatens water quality. 3. There is no subsurface collection system for this site at this time and with the removal of the pond all runoff should sheet flow away from the buildings. 4. To our best knowledge, all revised calculations, plans, supplements, and details have been updated correctly. Also, with the removal of the wet detention basin please discard those forms and calculations.

Box 1967 Wilmington, NC 28402 (910) 392-9325 Date: May 2008 SEA 03058- 9 Prepared by Cape Fear Engineering, Inc. 151 Poole Road, Suite 100 Belville, NC 28451 (910) 383-1044 DESIGN tVARRA TI VE General: The project site is designed to be a low density development located on the north side of US Highway 74/76 approximately one -tenth of a mile WNW of the east end of Malmo Loop Road (SR 1417) within Brunswick County, North Carolina. The project area to be disturbed is approximately 7.75 acres, including the sediment trap areas and stormwater pond. Drainage considerations are to be in accordance with NC DWQ storm water requirements. The intent of this project is to develop a temporary sales center with a septic system, a gravel parking lot and provide vehicular access, for construction vehicles, to the bridge crossing Alligator Branch. The road will be constructed of gravel through the entire length. Access from the north end will be through the area north and east of the crossing which is presently operating on a separate clearing and grubbing permit. Existing Site: Site topography in the area is relatively flat. There is a ridge that transects the property south of the branch. Slopes are typically less than five (5) percent with the steeper slopes being adjacent to the branch. The area from the transecting ridge toward the wetlands is divided into small, easily manageable drainage sub -areas by several more ridges that run from the main ridge — west to the wetland boundary. Vegetation consists of a loblolly pine — oak Canopy with the understory including dogwoods, sassafras, huckleberry, panicum grasses and lichens. Subsurface soils are mapped as Baymeade and Blanton fine sands. These soils are well -drained to moderately well drained soils which have typically slow surface run-off. In the area along the branch the soils are mapped as Muckalee Loam (hydric). It is our intention to disturb this area very little and to control any sediment -laden run-off with silt fences along the wetland boundary. Proposed Improvements: Improvements proposed include a temporary structure, a septic system and a gravel parking lot. Previously permitted is a 26' wide temporary gravel access road with a 10,000 foot square gravel pad to "set-up" construction equipment and as a storage area for the materials necessary for the construction of the raised bridge. Drainage Calculation Considerations: Drainage for the sales center and parking lot should sheet flow from the building and parking lot into the wet detention basin that should drain to the surrounding wetlands at the north end of the site. Drainage on the rest of the site will sheet flow to and across the road to a roadside swale or to silt fences where the slopes are flatter and near the top of the drainage divides. Erosion Control Considerations: The road -side swales will convey run-off to the temporary sediment traps. Areas that are flatter and near the top of the drainage divides will be protected with silt Fence and in one case a temporary diversion will direct run-off from a swale to a sediment trap. All the areas are naturally small and manageable. Disturbance will be held to a minimum. Also, any area drainage to the wet detention pond should provide ample sediment storage and will be utilized as a temporary sediment basin during construction. Once complete the gravel from the roadway will be removed from the area and disposed of properly. The disturbed area will then be filled with the topsoil strippings from the future permanent road, and fertilized, mulched and seeded according to the specifications and season. Erosion Control Measures and Sequence: a. Temporary construction entrance. b. Temporary sediment basins. C. Silt fence. d. A temporary diversion earthen dike. e. Temporary seeding should construction be halted for the specified time limit (refer to specifications) f. Temporary erosion control measures shall not be removed until the future road has been completed and the area is restored to it's previous condition a good vegetative ground cover has been established. Maintenance Considerations: During construction, the Contractor shall be required to inspect and repair as needed all erosion control devices after any significant rain event. Any measure found not performing its intended function should be repaired immediately, Upon completion of construction and establishment of permanent ground cover, the Owner shall be responsible for maintenance on the project site. Erosion Control Specifications Erosion and Sedimentation Control L01 General: The contractor shall be responsible for erosion and sedimentation control within the construction limits; for prevention of sediment laden runoff leaving the construction limits or entering ditches, streams or water impoundments; and for implementation of necessary erosion and sedimentation control measures to meet the requirements of the North Carolina Department of Environment, Health, and Natural Resources. The Contractor shall also be responsible for all damages or fines resulting from erosion or sediment laden runoff in the execution of his contract. 1.02 Construction Sequence: While the use of erosion and sedimentation control devices is especially important on areas of steep topography, easily erodible soils and sites in close proximity to water courses throughout the construction period, the control measures should be installed prior to the commencement of land clearing and shall be fully maintained and periodically inspected until final restoration and stabilization is completed. Un-restored cleared areas shall be kept to a minimum. Disturbed areas ahead of construction shall only be accomplished on those segments for the shortest practical distance as required for continual progress. Final restoration shall not be delayed until completion of the project but will be carried out in phases as the work proceeds. Under no circumstances will any areas be left denuded for more than (30) thirty calendar days without some form of stabilization until final restoration is complete. 1.03 Sedimentation: Control Measures: The following are some of the sediment control devices or measures that may be required to prevent sedimentation of streams, water courses, or drainage structures: 1. Earth berms and/or diversion and intercept ditches. 2. Sediment traps 3. Silt fences - not to be placed in streams or ditches perpendicular to flow. 4. Temporary diversion earthen dike 5. Gravel construction exit r 1.03.1 Erosion Control Measures: Some of the soil erosion control measures which may be required in this contract are: l . Earth slope protection 2. Diversion channels 3. Preservation of existing vegetation 4. Matting of re -seeded areas 1.03.2 Detail Drawing: Examples of sedimentation and erosion control details are shown in these plans for installation at locations designated on the plans or as otherwise required by the regulating agency, or the owner as work proceeds. 1.04 Stream Protection: Where construction activities are necessary in close proximity to streams, and other waterways, they shall be performed in a manner that does not contribute to degradation of or blockage of the stream -flow. In order to prevent possible degradation or blockages, the contractor shall be required to: 1. Keep all construction debris, excavated materials, brush, rocks, refuse and topsoil as far from these waterways as possible. Restrict machinery operation or stream crossings in waterways to the extent necessary for construction of utilities crossings. 2. If construction work areas are necessary in a waterway, they shall be protected as indicated on the plans. 1.05 Construction Access: The travel of equipment to and from the construction areas shall be minimized not only to protect areas that will not be denuded, but also to prevent the spreading of sediment within and outside of the construction areas. Therefore, special construction equipment travel corridors will be established for this use and instructions shall be issued for their use. Use of these corridors must be fully enforced. Other non -essential traffic will be restricted or discouraged. Indiscriminate and convenience traffic shall not be allowed. 1.06 Stockpile/Barrow Areas: The Contractor shall be responsible for selecting, obtaining and maintaining stockpile or borrow areas which he may require to complete the contract. He is also required to design and incorporate all necessary sediment and erosion controls measures necessary to prevent erosion and contribution of sediment to adjacent areas. The Contractor is responsible to obtain all necessary permits or approvals for borrow or spoil areas outside the construction limits. 1.07 Disposal of Excess Water From Excavations: The Contractor shall practice management of excess water pumped from excavation to reduce the production and spreading of sediment. Pumped water shall be discharged onto stabilized surfaces and allowed to filter through existing vegetation; if possible, otherwise, additional control measures may be necessary. If ditches are required to remove pumped water Frorn construction excavations, they shall be given the same consideration as any other man- made waterway and they shall be stabilized as to not degrade and produce sediment. 1.08 Excavation and Backfill: Excavation shall be closely controlled and all the material removed from the excavation shall be selectively stockpiled in areas where a minimum of sediment will be generated and where other damage will not result from the piled material. Drainage ways shall be protected at all times and the placement of material in Drainage ways for convenience shall not be allowed. Backfilling operations shall be performed in such a manner that remaining trees are not damaged. 1.09 Final Grading and Seeding: Finish grading, top -soiling, seeding and/or sodding shall be performed after the construction phase is complete. Permanent vegetation of the areas, that have been disturbed, shall be re-established as rapidly as possible. If the completion of the construction activities do not coincide with a season in which permanent vegetation can be generated, an interim or temporary program is required. This shall include soil conditioners and mulching as necessary for soil stabilization. In any case, sediment and erosion controls shall be installed promptly and their maintenance assured. 1.10 Approval: The approved Erosion Control Plan will be provided by the O�,�ner. Any standard conditions relating to soil erosion and sediment control issued to the Contractor as a part of any permits shall be available at the job site at all times.

G. Exum & Hood Creek, LLC Compass Pointe Temporary Drive and Commercial Center Hwy. 74, Brunswick County FOR THE construction, operation and maintenance of a 24% low density development in compliance with the provisions of 15A NCAC 2H .1000 (hereafter referred to as the "stormwater rules") and the approved stormwater management plans and specifications, and other supporting data as attached and on file with and approved by the Division of Water Quality and considered a part of this permit. The Permit shall be effective from the date of issuance until rescinded and shall be subject to the following specific conditions and limitations: I. DESIGN STANDARDS 1. This permit covers the construction of 197,103 square feet of built -upon area. 2. The overall tract built -upon area percentage for the project must be maintained at 24%, as required by Section .1005 of the stormwater rules. 3. Approved plans and specifications for projects covered by this permit are incorporated by reference and are enforceable parts of the permit. 4. The only runoff conveyance systems allowed will be vegetated conveyances such as swales with minimum side slopes of 3:1 (H:V) as defined in the stormwater rules and approved by the Division. 5. No piping is allowed except that minimum amount necessary to direct runoff beneath an impervious surface such as a road or to provide access. 6. Roof drains must terminate at least 30 feet from the Mean High Water line of surface waters. Page 2 of 5 State Stormwater Management Systems Permit Number SW8 080107 MOD II. SCHEDULE OF COMPLIANCE Projects covered by this permit will maintain a minimum 30-feet wide vegetative buffer between all impervious areas and surface waters. 2. The permittee is responsible for verifying that the proposed built -upon area does not exceed the allowable built -upon area. 3. The Director may notify the permittee when the permitted site does not meet one or more of the minimum requirements of the permit. Within the time frame specified in the notice, the permittee shall submit a written time schedule to the Director for modifying the site to meet minimum requirements. The permittee shall provide copies of revised plans and certification in writing to the Director that the changes have been made. 4. Prior to the subdivision and/or sale of this project, in whole or in part, the following deed restrictions must be recorded with the Office of the Register of Deeds: a. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number SW8 080107 MOD, as issued by the Division of Water. Quality under NCAC 21-1.1000. b. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the Stormwater Management Permit. C. These covenants are to run with the land and be binding on all persons and parties claiming under them. d. 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. e. Alteration of the drainage as shown on the approved plans may not take place without the concurrence of the Division of Water Quality. f. Construction of additional built -upon area in excess of 197,103 square feet will require a permit modification. g. Construction of additional impervious areas such that low -density requirements are no longer met will require a permit modification prior to construction. An engineered system will be required to collect and treat the runoff from all built -upon area associated with the project, including that area permitted under the low density option. h. Filling in or piping of any vegetative conveyances (ditches, swales,.etc.) associated with this development, except for average driveway crossings, is strictly prohibited by any persons. i. A minimum 30' wide vegetated buffer area shall be provided between surface waters and all impervious surfaces. 5. A copy of the recorded restrictions must be received in this Office within 30 days of the date of sale. 6. Filling in or piping of any vegetative conveyances (ditches, swales, etc.) associated with the permitted development, except for average driveway crossings, is strictly prohibited by any persons. 7. Prior to the development of any future area or additional phase noted on the approved plans for which an allocation of built -upon area has been made, a permit modification must be submitted to and approved by the Division. The modification must demonstrate that the built -upon area does not exceed the maximum amount permitted under this permit and that it meets the intent of low density development per the stormwater rules and available guidance. Page 3 of 5 State Stormwater Management Systems Permit Number SW8 080107 MOD 8. It has been observed that this temporary construction project is part of a larger common plan of development. Therefore, when these plans are modified to the final design, this project will be treated as a phase of the common plan of development, and the associated built -upon area will be included in the overall calculations of the common plan. 9. The permittee shall submit to the Director and shall have received approval for revised plans, specifications, and calculations prior to construction, for any modification to the approved plans, including, but not limited to, those listed below: a. Any revision to the approved plans, regardless of size. b. Owner or Project name change. c. Transfer of ownership. d. Redesign or addition to the approved amount of built -upon area. e. Further subdivision, acquisition, or sale of the project area. The project area is defined as all property owned by the permittee, for which Sedimentation and Erosion Control Plan approval was sought or for which a CAMA Major permit was issued. f. Filling in, altering or piping any vegetative conveyance shown on the approved plan. g. Development of the designated future development areas. 10. Swales and other vegetated conveyances shall be constructed in their entirety, vegetated, and be operational for their intended use prior to the construction of any built -upon surface. 11. During construction, erosion shall be kept to a minimum and any eroded areas of the swales or other vegetated conveyances will be repaired immediately. 12. The permittee shall at all times provide the operation and maintenance necessary to operate the permitted stormwater management systems at optimum efficiency to include: a. Inspections b Sediment removal. C. Mowing, and re -vegetating of the side slopes. d. Immediate repair of eroded areas. e.

' Seasonal High Watertable Estimate Sales Center Pond- Highway 74 Tract Leland; .North Carolina RFTS Job No. 368-08 Dear Mr. Lutheran: RFTS, is pleased to .provide testing services during the design of the sales center stormwater pond at the residential development (74 Tract) located off NC Highway 74 near Leland', North Carolina. DESCRIPTION OF ACTIVITIES AND FINDINGS As requested, our staff visited the _ site on May 9, 2008- to estimate the seasonal high watertable atone location within the area of the proposed. stormwater. pond. Seasonal High Watertable Estimates A -hand auger boring .was advanced to depth of approximately 13 feet.below. the ground surface'within-the area of.the proposed.pond. The Iocation of the hand boring was marked in the field with flagging for future identification. The encountered soils were. logged and . .visually classified by- depth and a Munsell Soil Color Chart was used to. determine .the hue, value,' and chroma of the visually distinct soil layers. Our soil logs are presented in Table 1.. . Sales Center Pond Soils encountered'in our'bonng location consisted entirely of interbedded relatively clean sands (USCS Soil Groups `SP', `SP-SM', and `SP-SC') through the boring termination depth of 151 inches below the existing site. ground surface. Comparison of the soils to the Munsell Chart suggests the presence of 'a' of .'aerated ' soils indicative of their .'occurring above the seasonal high water table extending to a depth of approxiinatdly 85 inches below , the, existing ground surface. No : water was measured in the' borehole ' through the depth investigated..However, soils appeared to be very moist in the lower 133 to.-155 inches below the ground. surface. 1305,3A Carolina'Beach Ave N Ofiice:-910-458-1377 CarolinaBeach,:Noith Carolina 28428 Fax: 910-458-5261'.

Dear Sirs: The above -mentioned tract was evaluated to determine the extent of any potential 404-wetlands. Wetlands were identified using the U.S. Army Corps of Engineers (C.O.E.) Wetlands Manual - 1987 edition. Wetlands were identified using a three -parameter approach incorporating soils, vegetation, and hydrological indicators. This tract is located north of Highway 74/76, west of Leland in Brunswick County. The tract totals approximately 40.85 acres. Wetlands were observed on the tract and are represented on the wetland survey for Compass Pointe Temporary Driveway & Commercial Center, prepared by Cape Fear Engineering, Inc. and dated 5/7/08. If you have any questions or concerns, please contact me at (9 10)795-03 19, (910)297-1282, or by e-mail at tgullevCcr�email.com. Sincerely, �_ I .I' J.

The Level Spreader Supplement and 0&M document that is now available on the website does not appear to be appropriate for use at the outlet and ponds that discharge to wetlands where there are no buffer rules and the waters are not classified SA. Up until now, it has been acceptable to utilize a level spreader design with the old O&M form when buffers and SA waters are not an issue. The new level spreader design involves the installation of a diverter box, by-pass swale, and requires a large area for filtration. A level spreader constructed in accordance with the new BMP manual is a BMP in itself. We have not been informed that the new design is required in all cases. Please allow the use of the level spreaders as proposed or allow the use of large rip rap energy dissipaters designed to provide non -erosive flow instead. Otherwise, we will need the current policy/rule concerning the requirement for these new level spreaders systems at the outlets of the proposed wet detention ponds in order to justify to our client the design expense and area of land necessary to install these systems. 2. The pipe between lots 3 & 4 is being relocated per your request. 3. The vicinity map is being revised per your request. 4. Bert has not named the project anything other than the Highway 74 East Tract at this time. If and when he decides to name it something else, we will submit a name change form as required. 5. The last time I checked with you, you implied that Ed was working on a policy concerning the requirement for JD or Corps verification. At this time a policy has not been received concerning this matter. The last Policy that I am aware of concerning SW Permits and JDs did not require a JD or Corps verification if there were no impacts proposed. In fact, I was recently informed that even the 401 Program can not require a JD. Is there a new policy regarding this matter from the Director? Securing field verification from the Corps at this point could take a couple of months. Considering this was not written policy last month (if it is now) it seems that there would be a period before it is officially required. We will forward you the requested information as soon as you have the time to address the questions, so that we can get you everything that you need.

The application is incomplete and cannot be accepted for review until the following items are provided: 1. Is there a reason why the Level Spreader O&M document is not in the standard format as on our website? Please provide completed Level Spreader supplements, initialed checklist, and signed O&M documents from the website. 2. The pipe in-between Lots 3 & 4 leading into the forebay for Pond 3 needs to be relocated to the next property line over so it can enter the forebay at a point further away from the main pond to allow the forebay to function properly. 3. Please label Highway 74 on the vicinity map. 4. What is the name of this subdivision? I can't imagine Bert has gotten to this point and doesn't have a name yet. We'll need the name before we issue the permit. 5. Please submit a copy of the ACOE approved jurisdictional wetland map, or have the ACOE representative for Brunswick County send me an email indicating that they have been to the site and have received the wetland survey map, and are OK with it.
