I am unable to accept the application for processing until the following items are provided. I. An original signature on the application. All three application booklets submitted were copies. Please do not bind the application as part of a booklet. You need not submit three copies - the original alone will do. 2. Please initial page 4 of the application. 3. Please report the built -upon area in square feet. It is easier for me to calculate and verify the BUA if it is in square feet. a. Meeting low density requirements is more than just meeting a magic number. It also involves the location of the built -upon area in relation to the receiving stream and the clustering of that built -upon area. It appears that a pocket of high density is occurring at the southeastern end ofthe project, where the dry stack and parking lot are located. I am requiring that an infiltration system be designed for the dry stack and east parking area. The west parking area is OK, however, I would like to see the parking lot moved as far from the water as practicable. The 30' buffer in the rules is just a minimum - as much as possible should be provided. S. Please dimension the buildings and parking. 6. Please show roof drain locations for the drystacks. 7. Please accurately report the site area you used to calculate the density on the application. The site area used to demonstrate low densitymust also exclude the area of the existing basin, sinvQ it is below NMW. The 13.26_ acre area you have used appears to include the basin. 8. Please show sufficient spot elevations to determine the drainage flow directions. i N.C.

If the existing 1,07 acres of built -upon will be removed, or new built -upon area will replace it, (e.g., where the new drystack building is built over the existing concrete pads) please do not report it as existing on the application. It appears that the only existing BUA that will remain after development is the marina house. Tlie existing gravel will become part of the new parking lot and the concrete pads will be removed to make way for the new dry stacks. You may not subtract the existing built -upon area from the proposed BUA. The total built -upon area that will remain after development (including the existing that will not be removed or replaced) must be included in the total. These are the main items I saw during the initial review. In the interest of saving time and money, I will hold the application until September 9, 2002. If you need additional time, please respond in writing (mail or fax) with the expected date of the submittal.

Stormwater Management Plan Carteret County, North Carolina TRC 1129408 0020 00000 Dear Linda, We have received your memo dated August 27, 2002 with comments on the stormwater application for the project referenced above. We offer the following responses to your comments. (Please see our letter dated September 9, 2002 requesting a time extension for response to your comments until this (late.) We believe there are two separate issues that need to be addressed from your comments: first, the acceptance of a complete stormwater application package, and secondly, the stormwater management plan design and any associated corninents on the design - We will address the application acceptance first. Comments I and 2 had to do with completeness of our application. We did not include an original signature application and page 4 of form SWU-101 was not initialed, which were oversights on our part. Please find attached an original and copy of the completed application with these iterns included. With this submittal you have now received three sets of plans, three sets of project narrative including calculations, processing fee of $420, one original and one copy of Stornwater Management Permit Application form (SWU-101, rev 3.99) and one copy of the Low Density Supplement (SWU-104, rev 3.99). According to Item V1. Submittal Requirements (SWU-101), these are the items needed for a complete application package. In addition we have reviewed NCAC 15A, Subchapter 21-1.1003 ltcm (g) and have included all applicable items as supporting documents and information in this package. Therefore, we believe that we have fully complied with the requirements for a complete application submittal and acceptance and therefore you should consider the date of.receipt of this letter as the start of the review process. We would like to make sure that you are aware of the following background inforrnation- We have been working on this project extensively for nearly three years with the Customer -Focused Solutions TC Triangle, Ince stormwater management plan design being a major element. As part of this process, I have had numerous conversations with Scott Vinson of the Wilmington Regional office and a meeting with him in Wilmington and Gene Cobb of this office on June 8, 2000, and an additional meeting with him at the project site on October 26, 2000. We have also had numerous discussions with Jeanette Powell (formerly of the Raleigh office) and Todd St. John and Steve Kroeger of your state office, including a meeting with the same parties on October 23, 2000. All discussions were aimed at the development of a storniwater management plan design meeting both the stormwater regulations for the project area and providing a workable solution for project completion. Items discussed were high density versus low density, BMP's as may be needed, wetlands, existing impervious area, stormwater discharge, etc_ Based on the direction received during these meetings and conversations from State staff and extensive review of the North Carolina regulations and stormwater design references, we designed a stormwater management plan that we feel meets or exceeds all requirements. The second general issue raised by your comments is related to the project design. We offer the following responses to your Comments 3-9. Once we have received the requested information and any additional review comments from your complete project review, we will submit revised plans, narrative, etc., for continuation► of the approval process. 3. We will report the area in square feet. 4. Please provide to us a reference to the regulation(s) that allows for a project site (one piece of' property) to be divided into separate tracts of laird for stormwater penr►itting purposes. We have been enable to locate arty reference to tills ISSlle. We will review the 30' buffer and provide additional butler, i f passible. 5_ Building and parking dinlens1011s will be added. 6. Roof drain locations will be added to the plans_ 7. The canal and basin area is included in the 13.26 ac_ In numerous past stormwater management plan design and approvals through the State of North Carolina; we have included bodies of water contained within the property as pervious area and have therefore used similar area calculations for this project. Please provide to us reference to the regulation(s) that excludes use of the area for the existing canal and basin in the low -density calculations. Likewise, we excluded .the land area of the 404 wetlands in our low - density calculations at the recommendation of State staff, but request reference to the regulations) that excludes this area from use in those calculations. S_ Spot elevations will be added to the plans. 9. We calculated the density subtracting the existing impervious area as agreed in our June 8, 2000, meeting with Scott Vinson. At his request, we provided a survey showing the existing impervious surface areas for record prior to proceeding with this project. 'Therefore, we request documentation referencing how to include existing impervious area ill Customer -Focused Solutions T C Triangle, e, Inc. density calculations. We have spent considerable time designing this site and stormwater management plan based on previous conversations with and direction by agency personnel and are concerned about the different direction implied in your memo. We would request and appreciate your clarification. We thank you for your review and response. Please call if you need additional information or discussion in any way.

Our meeting with Dorney this morning went better than I expected. I'm optimistic about working out a wetlands discharge. John actually seemed to be a proponent. The bad news is they want to do a site visit as the next step and can't get out to the site for another month at the earliest. Roger will be here tomorrow and/or Friday morning.

What I get out of this discussion is that your client is not eligible for a low density permit and it appears now that your client must propose a plan that will meet the requirements of a high density permit.

I participated with Rick Baker in some of the meetings that you make reference to. A .large part of our present pred..icament is that: we came away with quite different understandings than Linda has given to us currently. As a result, we're needing to understand what if any options we have for treating any part of our site in a way that you can permit. I don't want to get Scott, Jeanette, or Todd caught in any kind of rr_oss-fire if for no other reason they were kind enough to meet with us and offer their honest opinions. neither do we want to argue with Linda. Rick, this site is an old disturbed site. It's had a boat -building operation and a mobile -home development on it at one time or another. The two Richards brothers have cleaned it up so it looks pretty decent now, but still remaining are the concrete floor slabs from the original boat shop. There's over an acre of existing concrete slabs. There's about seven acres of wetlands within the > property that have been previously disturbed by ditching (for mosquito control). It seems to me that there are a number. of .i.ssues that are peculiar to this site that could have some bearing on how you could approach it for permitting.

Richards, Jr. Cape Lookout Marina, Inc. 3315 Old Forrest Road Lynchburg, VA 24501 Subject: REQUEST FOR ADDITIONAL INFORMATION Stormwater Project No. SW8 020934 Cape Lookout Marina Carteret County Dear Messrs. Richards and Richards: The Wilmington Regional Office received a Stormwater Management Permit Application for Cape Lookout Marina on September 30, 2002. Enclosed please find the rule references you requested in your letter. Please note that implementation guidance regarding the exclusion of the area below MHW and wetlands from the site area which is used to calculate density was originally implemented in 1988 as a Directive, and incorporated into the Standard Operating Procedure in 2001. As far as site area is concerned, I had originally excluded the area of the entire new basin, but I should only have excluded the area of the existing basin, so I can give you back 1.18 acres, for a total site area of 11 acres. The rule regarding pockets of high density is found in NCAC .1003 (d). This allows the Division to conduct a review of the project, on a case -by -case basis, to ensure that no one area of the project is loaded up with such an amount of built -upon area that the runoff from that area might threaten water quality. It has been determined by at least four DENR staff that there is a pocket of high density on the project in the area of the dry stacks. There is no guidance on the inclusion of existing built -upon area other than what has been considered accepted practice over the 15 years that the stormwater program has been in existence and common sense. It must be understood that the rules do not provide a section on how to permit development activities at sites with existing built -upon area, except in regards to offsite runoff. Additionally, the whole issue of existing built -upon area becomes moot if the site plan shows that the proposed BUA amount will exceed the existing BUA amount. During my 10 years here I have permitted a handful_of_projects.with existing built -upon -area. For example, if an old . -- project had existing built -upon area, but was now proposing to add onto the existing building and parking areas, that project could maintain the limited built -upon area aspect of low density development by calculating the density as follows: 1. Determine the project site area. This is the area within the property boundaries, above MEW and minus wetlands (if applicable). 2. Add up the amount of built -upon area that existed prior to 1988. Subtract the total of #2 above from the project area (41). This is the Adjusted Site Area. 4. Multiply the Adjusted Site Area by the appropriate density factor. In the 20 coastal counties this is 25% for SA and SAORW waters, 30% for all others. This is the maximum amount of new impervious area that can be constructed on the project. As long as the proposed BUA is less than or equal to the maximum, the project can meet one aspect oflow density development. NGDENR N.C.

Richards and Richards December 6, 2002 Stormwater Project No. SW8 020934 This method is generous in that it will generally result in a larger maximum BUA amount than the normal method of adding up -all the BUA (exishng'and proposed) and comparing it to the maximum allowable amount obtained by multiplying the site area by either 25% or 30%. I look forward to receiving a complete submittal after you have a chance to apply the rule cites contained in this letter and after incorporating any comments from the upcoming meeting. I will not be able to attend the meeting, but I believe Noelle Lutheran will. She can address both ston-nwater and wetlands issues. I believe all the issues have been discussed at least twice, based on the comments I received from Scott Vinson and Jeanette Powell. Hopefully, a third meeting will clear up any and all misunderstandings. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office within 30 days after the scheduled meeting, around January 25, 2003, 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 Division is allowed 90 days from the receipt of a completed application to issue the permit. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation ofNCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.

Stevens, Director 5r-" ,� _ ��_� Division of Water Quality Memorandum To: From: Subject: State Stormwater Management Program Staff Kerr T. Steven Implementation Guidance for the State Stormwater Management Program The Division of Water Quality, formerly the Division of Environmental Management, has issued four stormwater Directives over the past 12 years. These Directives have outlined interim policies and guidelines for the review of stormwater projects under NCAC 2H.1000. New stormwater management rules went into effect in September 1995, and many of the topics covered by the four Directives were incorporated into these rules - All policies established under the four Directives have been superceded by the September 1995 2H .1000 rules and any subsequent revisions. This includes the policy of allowing chlorides testing to determine if the SA design criteria should be applied to a project submitted under the 2H .1000 rules. The rules clearly state that if the project is within 1/2 mile of and draining to class SA waters (as defined in the schedule of classifications) then the project will be limited to a low density threshold of 25%n built upon area or the use of infiltration or approved alternatives for a I V2 " design storm. The only way to change the classification of a stream from SA is to go through the formal stream reclassification process. The administrative issues from the previous four Directives have been consolidated into the attached Standard Operating Procedure, dated April 24, 2001, which provides staff with implementation Crfor issues not specifically covered by the existing NCAC 2H .1000 rules. This information is for your immediate use in implementing the State Stormwater Management Program . If you have any questions, please contact either Bradley Bennett at (919) 733-5083 ext. 525, or Darren England at (919) 733-5083, ext. 545. NCDENR Customer Service 1 800 623-7748 Division of Water Quality 1617 Mail Service Center Raleigh, NC 27699-1617 (919) 733-7015 s STANDARD OPERATING PROCEDURE STAFF IMPLEMENTATION GUIDANCE FOR THE STATE STORMWATER MANAGEMENT PROGRAM 15A NCAC 2H :1000 - Under the early version of the NCAC 2H.1000 stormwater rules, four directives were issued which outlined various procedures to be followed, provided design guidance, and clarified gray areas of the rules. Many of the issues contained in these four Directives were incorporated into 15A NCAC 211.1000 during the 1995 rule changes. This SOP consolidates those remaining issues and provides guidance on implementing the State Stormwater Management Program under NCAC 211.1000. This SOP supercedes all previous Directives. Guidance provided below falls under the following subject headings: 1. Calculating Built Upon Area 2. Measuring Distances for HQW & SA Waters 3. Clearing and Grading Projects 4. Vegetated Filters 5. Water Dependent Structures 6. CommonlMaster Plan of Development 7- Areas of Environmental Concern (AECs) 8. Minimum Lot Sizes 9. Swales 10. Cited Document - Overview of Wet Detention Basins 11. NSW Buffers Calculating Built Upon Area In calculating built -upon area for the low density option on projects adjacent to tidal waters, the project` area shall include ands inland from the mean high water line. Irregularly flooded wetlands above the mean high water line may be credited as pervious area. In addition, isolated wetlands may also be credited as pervious area. However, for a project with a relafNdly-large portion of wetlands, this could result in pockets of high density. A case-b - ase evaluation should b ned b DW staff for low densit projects to ensure, that no areas within the pro)'ect site are of such high density that stormwater runoff threatens water quality. . - 2. Measuring Distances for HQW & SA Waters Determining "within — mile of and draining to..." as defined in the rules for HQW (one mile) and SA waters (one-half mile) shall be measured `as the crow flies' from the Mean High Water line. This distance should not be measured along the stormwater flow route. Clearing and Grading Projects Some development projects will be submitted in which the only immediate activity is clearing and grading. The type of site development is not known and will be determined at a later time. In these cases, DWQ will request that the applicant submit a general permit application. The general permit will cover the clearing and grading activity only and will require the permittee to modify. the permit when final development plans are known, the property is subdivided, or the property is sold. 4. Vegetated Filters Wet detention ponds designed for 85% TSS removal are required to discharge through a thirty foot.,vegetated filter to minimize erosion and to provide additional pollutant removal. There may be projects where a developer finds it difficult to construct a functional vegetated filter, and must discharge. directly back to the watercourse. In these instances, additional storage should be provided to compensate for the lack of a filter and the pond must be designed to remove 90% TSS instead of 85%. It is recommended that the post -development discharge rate from the pond not exceed the pre -development rate from the project for the I0-year, 24-hour storm as defined in the DLR Erosion and Sediment Control Manual. 5. Water Dependent Structures Low density design requirements include a 30' vegetated buffer, however, there are some low density projects which propose water dependent structures such as boat ramps and bulkheads that must necessarily be located closer than 30'to the surface waters. These types of structures can be permitted under the low density option, and must also meet the requirements described in the "Other Projects" permit found in NCAC 2H.1003(d)(3)(C). Water dependent structures as defined in NCAC 2H.1002(20) are allowed within the 30' buffer area, and reasonable access and slopes are also permitted. Proposed water dependent structures that are not.part of a low density project can be, permitted under the "Other Projects" option. 6. ..Common/Master Plan of Development A common plan of development is defined as all development associated with the construction of the submitted project, not limited to within the property boundaries, regardless of how long it takes to fully develop. For example, outparcels that are to be subdivided and sold or leased out of a larger tract must be accounted for at the full buildout potential in the control system's design. Other examples are future development and access roads that are a part of the project, but not neces sari ly'l ocated within the property boundary which are needed to provide access to the proposed project. In the case of large phased developments, such as golf courses with subdivisions, a Master Plan will be required prior to permitting any part of the development. The Master Plan will be reviewed by DWQ and comments regarding the overall development, densities, pockets of high density etc. will be made. Subsequent submittals for individual phases will be permitted based on compliance With the Master Plan. Changes to the Master Plan after 04.24.01 PaEe 2 of 4 development begins will require another review by DWQ for continued compliance with the storrrnwater rules. DWQ must determine on a case -by -case basis whether the permit will be issued for the Master Plan or for individual phases. If the Master Plan will be permitted, a complete application package will be required in order to do a full review and issue a permit. Each modification after that will require a revised Master plan submittal including a new permit review fee. Areas of Environmental Concern (AECs) To insure consistency with CAMA requirements for low density subdivision Iots that straddle the 575' ORW AEC line, the built -upon surface of the entire lot should be considered in the AEC if 50% or more of the lot area is in the AEC. If less than 50% of the lot area is in the AEC, none of the built -upon surface of that lot should be included in the AEC. For other types of low density projects, the actual built -upon area within the AEC should be calculated. The most restrictive built -upon area between DWQ and CAMA is the one that applies. 8. Minimum Lot Sizes Questions have arisen as to whether every lot must be equal to or greater than the minimum lot requirement for the low density option. The average lot size of the entire project must conform to the minimum requirement. However, if a few lots fall slightly under the requirement because of restrictions in topography, natural boundaries, etc., the project could be approved. A guideline to follow is to have no more than 10% of the lots under the required size, and no lot less than 90% of the required size. Modifications to this guideline can be considered on a case -by -case basis depending on soils, slopes, sensitive areas to be protected, etc. For development outside the coastal counties that drains to HQW or ORW waters, local governments typically use R-40 as a zoning designation to indicate that the minimum lot size is one acre. The "40" stands for40,000 square foot lots. It is generally assumed that the roads and rights -of -way not owned by the homeowner typically account for the remaining 3,560 square feet. Therefore, the local government designation for a 40,006 square foot lot is sufficient to meet the DWQ requirement for a one acre lot size, even though the actual lot size is smaller. If a development wants to cluster 100 single family dwelling units away from surface waters on a 100 acre development,'the project could be approved at the discretion of DWQ. A properly designed cluster project must allow runoff to sheet flow through the remaining open area. In addition to the lot restrictions, deed restrictions preventing built - upon area within the open area will - be required. If other features such as clubhouses, parking lots, community areas, parks, etc. are included in the project, it will be necessary to ensure that the appropriate built -upon area is maintained through deed restrictions. 9. Swales It may be necessary to rip -rap ditches in highly erodible areas (steep slopes, poor soils, etc.) of a low density project. While vegetated swales would be preferable from an infiltration/pollutant removal standpoint and should, be utilized where feasible, the erosion from an improperly stabilized swale could result in. significant water quality degradation. Proper consideration for existing topographic conditions should be given during the design phase in order to appropriately use rip rap in grassed Swales. 10. Cited Document - Overview of Wet Detention Basins The "Overview of Wet Detention Basins" cited in the rules has been replaced by the Best Management Practices (BMP} Manual. Design guidelines for stormwater management measures including wet detention ponds, dry detention ponds, constructed stormwater .... _ wetlands, infiltration systems, sand filters, Norefention areas, ;grassedswales and filter strips can be found in the BMP Manual. The most recent version of the BMP Manual should be consulted. 12. NSW Buffers All projects must meet applicable NSW buffer requirements prior to permit issuance. To date, buffer requirements are in place in the Neuse River Basin and the Tar -Pamlico River Basin. 04.24.01 Page 4 of 4 -EIINR - ENVIRONMENTAL MANAGEMENT T15A. 0211.1000 . w � � management in accordance with this Section. Local governments with delegated Sedimentation/Erosion Control —� Programs often implement more stringent standards in the form of lower thresholds for land area disturbed. In these situations, the requirements of this Rule apply only to those projects that exceed the state's minimum area of disturbance as outlined in G.S. 113A-57. Specific permitting options, including general permits for some activities, are outlined in Paragraph (d) of this Rule. (c) Development activity with a CAMA major development permit or a Sedimentation/Erosion Control Plan approved prior to January 1, 1988 are not required to meet the provisions of these Rules unless changes are made to the project which require modifications to these approvals after January I, 1988. A Projects subject to the permitting requirements of this Section may be permitted under the following stormwater management options: (1) Low Density Projects: Projects permitted as low density projects must be designed to meet and maintain the applicable low density requirements specified in Rules .1005 through .1007 of this Section. The Division shall review project plans and assure that density levels meet the applicable low density requirements. The permit shall require recorded deed restrictions and protective covenants to ensure development activities maintain the development consistent with the plans and specifications approved by the Division. (2) High Density Projects: Projects permitted as high density projects must be designed to meet the applicable high density requirements specified in Rules .1005 through .1007 of this Section with stormwater control measures designed, operated and maintained in accordance with the provisions of this Section. The permit shall require recorded deed restrictions and protective covenants to ensure development activities maintain the development consistent with the plans and specifications approved by the Division. Stormwater control measures and operation and maintenance plans developed in accordance with Rule, 1008 of this Section must be approved by the Division. fn addition, NPDES permits for stormwater point sources may be required according to the provisions of 15A NCAC 2H .0126. (3) Other Projects: Development may also be permitted on a case -by -case basis if the project: (A) controls runoff through an off -site stormwater system meeting provisions of this Section; (B) is redevelopment which meets the requirements of this Section to the maximum extent practicable; (C) otherwise meets the provisions of this Section and has water dependent structures, public roads and public bridges which minimize built -upon surfaces, divert stormwater away from surface waters as much as possible and employ other best management practices to minimize water quality impacts. (4) Directors Certification: Projects maybe approved on a case -by -case basis if the project is certified by the Director that the site is situated such that water quality standards and uses are not threatened and the developer demonstrates that: (A) the development p lans a nd s pecifications i ndicate s tormwater c ontroI m easures w hich s hall be installed in lieu of the requirements of this Rule; or (B) the development is located such a distance from surface waters that impacts from pollutants present in stormwater from the site shall be effectively mitigated. (5) General Permits: Projects may apply for permit coverage under general permits for specific types of activities. The Division shall develop general permits for these activities in accordance with Rule. 10 13 of this Section. General Permit coverage shall be available to activities including, but not limited to: (A) construction of bulkheads and boat ramps; (B) installation of sewer lines with no proposed built -upon areas; (C) construction of an individual single family residence; and (D) other activities that, in the opinion of the Director, meet the criteria in Rule .1013 of this Section. Development designed to meet the requirements in Subparagraphs (d)(1) and (d)(3) of this Paragraph must demonstrate that no areas within the project'site are'of such high density that stormwater runoff threatens water. quality. (e) Applications: Any person with development activity meeting the criteria of Paragraph (b) of this Rule shall apply for permit coverage through the Division. Previously issued Stormwater Certifications (issued in accordance with stormwater management rules effective prior to September 1, 1995) revoked due to certification violations _ must apply for permit coverage. Stormwater management permit applications, project plans, supporting information and processing fees shall be submitted to the appropriate Division of Environmental Management regional office.

Brief update: The stormwater meeting at Harker's Island will not happen prior to the first of the year. Basically, the Wetlands Group personnel do not want to meet without Linda Lewis being present, and she will not be available until after the first of the year. Rick and i met with Jeanette Powell last Friday afternoon. You may remember that she formerly worked with the state - level stormwater permitting unit here in Raleigh. We discussed our project and stormwater permitting status and gave her copies of our pertinent correspondence. She asked to review the materials and will respond to us this week with some suggested response. I asked her to consider personal roles for herself ranging from advisor to active permitter. have talked by phone with Todd St John of the Wetlands Unit and Noelle Lutheran of the Wilmington Regional Office (DNER). I'm anticipating from their remarks that Linda will hold to her ruling that we infiltrate the first 1-112 inches of stormwater from our designated "high -density" area. Noelle suggested that we have their regional Soils Scientist (Vincent Lewis) give us an opinion on the site infiltration capacity. I think the answer will be zero. However, I have called Vincent and left a message for a return call. He has previously been on the site with the County representative regarding the wastewater permitting, so I'm thinking he will not need to meet at the site to give us a ruling, Roger will be here tomorrow to touch base with Rick and I regarding any CAMA items I'll try to give you a report before the end of the week on any further developments.

As you may be aware, the proposed meeting in late December at the site did not materialize. The Wetlands Unit personnel do not want to meet at the site without your being present. We may yet request that you schedule for such a meeting at a later date, depending on further developments in pursuing other permitting options. This letter is to request that you hold our present application for an additional 30 days to allow us to further investigate whether we may legitimately claim the discharging option as shown in our current application. In this regard, we are seeking to establish the BUA that existed in 1988, as outlined in your letter. We have aerial photography from a 1989 flight that shows the site being used very intensively for a boat -building operation. It is apparent that there was significantly greater impervious area in existence at that time than is evidenced at present by the remaining concrete floor slabs. We would also request your guidance on the following issues. We are seeking earlier aerial photography to establish that the BUA circ. '89 existed also in '88. Does your policy establish any specific date as the threshold date for existing BUA? 2. Some significant portion of the site drains to the state road adjoining the property. Would your policy in any way restrict or limit -this existing drainage pattern_? 3.. In reviewing the General Statutes and Administrative Code provisions regarding stormwater permitting, we note in a section dealing primarily with local governmental permitting requirements (I SA NCAC 02H .0126 (10) (h)) the following language: "For programs with development/redevelopment draining to Customer -Focused Solutions RE TRC Triangle, Inc. SA waters, the following additional requirements must be incorporated into their program:... (ii) New direct points of stormwater discharge to SA waters or expansion of existing points of discharge to any constructed stormwater conveyance system, or constructed system of conveyances that discharge to SA waters, shall not be allowed. Expansion is defined as an increase in drainage area or an increase in impervious surface within the drainage area resulting in a net increase in peak flow or volume from the one year 24 hour storm. Overland shee flow of stormwater or stormwater discharge to a wetland, vegetated buyer or other natural area capable of providing treatment or absorption will not be considered a direct point of stormwater discharge for the purposes of this Rule... "(emphasis added). This wording seems to indicate that a stormwater discharge through a natural wetland is permittable for a public body. Is this provision not also pennittable for a private entity? 4. For your information, in late December we requested that Vincent Lewis meet with us to determine the suitability of the soils for infiltration. Mr. Lewis did so in early January and was able to identify a limited area at the northwest corner that might be suitable. We understand that a detailed field study will be required to establish an allowable infiltration rate if we are forced to this method of discharge. However, Mr. Lewis could not tell us if we could use any portion of the designated buffers for this purpose. Since the existing canals within and bordering the property create a lot of buffer area, we would be severely restricted in using this area if allowable only outside the buffer. What is your policy regarding this issue? 5. In further regard to Item #4 above, would the restriction for a 50-foot separation between an infiltration system and SA waters also apply to separation from the internal canals? Thank you for your consideration of our request and for your response by your most convenient means to our issues raised above. Please call if you need additional information or have questions.

Stormwater Management Plan Stormwater Project No. SW8 020934 Carteret County, North Carolina TRC 4 29408 0020 00000 Dear Linda, In response to our request for a 30-day time extension made in our letter dated January 24, 2003, we are providing the l-ollowing submittal. Included in this submittal are a photograph of the project site dated June 9, 1987, a letter from the distributor certifying photograph acquisition date and supplier (USGS), an enlargement of the photograph with boundary, wetland, canal and existing built upon area (BUA) hatching overlay, revised original signature application (SWU-101), revised low density supplement (SWU-iO4), and stormwater narrative including revised stormwater calculations. After receiving your letter dated December 6, 2002, with direction on calculating adjusted site area (ASA) clue to existing built upon area (BUA), we were able to locate an aerial photograph of the site dated .tune 9, 1987. At your direction of calculating BUA prior to 1988, we believe this photo should provide adequate documentation of the existing BUA. During the time of this photograph, this site was used as an active boat building/repair facility. On the enlargement, we have provided an overlay of two existing BUA's. Area 91 includes the gravel entrance, residence, parking and travel area and driveway access to two mobile homes located on the western peninsula. Please note in the southwest corner we have not included the light colored area, as we believe these to be boats that are not permanent impervious area. Area #2 includes at least two buildings (as can be seen by the shadowing to the west of each) covering the southern concrete slab and the area between the two northern concrete slabs, concrete slabs, parking, travel area around buildings and slabs, material storage areas, boat loading/unloading; and a driveway access on the eastern peninsula that may have been used for an additional boat loading/unloading into the canal. )` From the photograph, we have calculated the existing BUA for each area. These calculations area as follows: Area 41 = 41,513 sf (0.953 ac) and Area 92 = 113,212 sf (2.599 ac). Compared to the proposed BUA for final build out, Area 91 = 52,098 sf (1.196 ac) and Area #2 = 107,463 sf (2.467 ac), there is a net increase (4.6% of ASA) of BUA for area #i and a net reduction (-2.3% of ASA) for Area 92. F'or reference, Area 42 includes the area of pocket high density that you referred to in previous correspondence that at final build out will have a net decrease of BUA. In addition, we have calculated the allowable new impervious area using your formula in the December 6, 2002, letter. The allowable new impervious area from this formula is 1.862 ac. 'fhe total new proposed impervious area is 0. l 1 1 acre (3.663 ac proposed less 3.552 ac existing), all of which will be built on the western peninsula. Please see the attached revised project narrative with additional inlorniation and calculations for the above data. With this additional information provided and documented, it is our professional opinion that this project meets the requirements set forth for low density as provided in your correspondence and NCAC 211.1005.

TRC Triangle, Inc. 500 Glenwood Avenue Raleigh, NC 27603 Subject: DESIGN GUIDANCE Cape Lookout Marina, Inc. Stormwater Project No. SW8 020934 Carteret County Dear Mr. Baker: The Division received your letter of January 24, 2003, regarding several questions you had about the design requirements for the stormwater management system for Cape Lookout Marina. The policy regarding redevelopment projects has been fine-tuned over the years since 1995. We can accept a redevelopment application as long as the built -upon area existed within the 6 months prior to application. This application was received in September, 2002, therefore, we would consider a redevelopment permit for this site if the built -upon area existed in March, 2002. However, a redevelopment pen -nit still requires stormwater treatment to the maximum extent practicable. The Division will review the application to determine if everything has been done to provide adequate treatment for the design stone. The discharge of runoff into the existing State Road ditch is not restricted or limited, although it cannot be considered a vegetated filter because the DOT cannot guarantee that it will remain a ditch. As was previously detennined, the proposed side parking area is low density and can sheet flow across a minimum of 30' of vegetated area prior to discharge. The runoff from the concentration of built -upon area around the building, front parking area, and dry -stacks must be collected and treated in an engineered system. ff the runoff from this concentrated area can be collected, infiltrated, excess bypassed through a vegetated filter (subject to paragraph 5 on followitag page) and.lhcn directed into the road ditch, we won't have a problem. According to NCAC 02H.0126, where other rule requirements overlap, the more stringent will apply. Additionally, the rules in .0126 apply for the most part to stormwater discharges which require NPDES permitting. For any projects (public or private) on the coast, the regulations found in NCAC 2H.1000 apply. These rules require a 50' vegetated filter for the overflow from all infiltration systems that are within % mile of and draining to class SA waters, including tidal wetlands. The vegetated filter must be constructed in such a manner that a sheet flow condition across 50' of grassed area is created prior to discharge into the receiving waters. Direct point -source discharges into SA waters are prohibited. tfCDENR N.C.

There are several meanings attached to 30' and 50' "buffers". One can refer to the horizontal separation between the MHW line and an infiltration system. The other can refer to the 30' undisturbed vegetated area that is required between the MHW and all impervious surfaces for a low density project. The coastal rules require at least 50' between the MHW of class SA waters and the infiltration system, and 30' for other classes of waters. Per NCAC 2B.0301 (i) (1)(C), depending on when the canals were created, they may or may not be considered SA. If the canals were first created under an approved dredging project before November 1, 198b, they are considered SA, and the infiltration system would have to be sited a minimum of 50' from the MHW line. If the canals were created after that date, they are considered SC, and the engineered system (infiltration or otherwise) would have -to be sited a minimum of 30' from the MHW. A vegetated filter would not be required for the excess design storm bypass if the canals are determined to be class SC.. I hope this information answers your questions and guides you in the design of stormwater management measures for this difficult site. Please call or email me if you have additional questions.

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 report your title within the corporation as requested in Part 1.2 of the application. You must be at least a vice president in order to sign the application. The signature of an agent or consultant can be accepted only if accompanied by a letter of authorization. 2. Please add the nearest intersection of two major roads to the vicinity map. A major road is any 1, 2 or 3 digit NC, US or interstate highway. 3. As previously indicated to your consultant, meeting low density is not just a matter of number manipulation. Neither the, method used to calculate density, nor the fact that there is existing built -upon area on the site, will make any difference regarding the call that was made that a pocket of high density exists at this site. Please provide an infiltration system for the runoff from the drystack building and front parking lot. 4. Please report all built -upon areas in square feet on the appplication. For purposes of this apphcation, the numbers listed in column #1 should be the overall density of the site, excluding the wetlands. Column #2 should be used to report the numbers for the infiltration system you will be using to treat the runoff from the dry stacks and front parking lot. The parking lot along the western edge will not be required to provide infiltration as long as it will not have an inverted crown and will sheet flow across at least 30' of grassed area before entering SA waters. 5.

Jeanette and Scott Vinson met with these guys at least twice regarding their pending application. Its a new marina and drystack with parking. The overall density meets 25%, but according to JP and SV, the new drystack building and surrounding parking were considered a pocket of high density. The developers started looking for non-structural alternatives to treat the runoff. When I reviewed their application and said it was a pocket of high density, they acted like it was the first they heard of it and they alluded that some kind of agreement had been reached with SV and JP so that it wouldn't be considered high density. I talked to SV and JP and neither recalls making any agreement like that. At one time, they talked about using the wetlands as the treatment but Dorney and Todd St. John determined that the wetlands were too close to surface waters to be of any help in treating stormwater. I am requiring them to provide treatment for the 1.5" runoff from the drystack and the immediate parking area- the parking area on the opposite side of the marina is considered low density and has a 30' buffer to sheet flow runoff through. That's all I know. Linda Bradley Bennett wrote: > Linda, > I have received an email from Gene Cobb - TRC Triangle, Inc. - on this > project.

Take care, J I'" As far as the existing built upon area, f remember a discussion regarding removing the unused bua (slabs of concrete) to help lower the overall density to below 25%, thereby onlybaving to treat the HD pocket with an engineered system. This would allow a proposed walkway down the side of the inlet to sheet flow across vegetation for treatment and not be picked up by an engineered system. do know we had not come to a conclusion of how this project would be permitted through stormwater because of all the problems and for Rick to claim that there was no mention of a "pocket of high density" is wrong. Both Jeanette and I recall telling them about the pocket because it was the biggest problem and was holding up the SW permit. As far as any deal I "might" have made, I don't remember it. If I did make this "deal" that Rick is referring to then why didn't I go ahead and permit the project? Remain standing up for how you see this project because you are right. Don't give in to their pressure because when the day is over it will be you that permits this project.: ) I still don't uderstand how they got past Wetlands and CAMA.

They both claim they had no idea that a pocket of high density existed. It had something to do with the calculation of built -upon taking into account the existing built -upon to demonstrate low density. Apparently, after the initial meeting with you, they discovered they could not do infiltration because of the high water table and unsuitable soil. They then attempted to get the wetlands approved as the treatment, but the policy to allow it was not implemented and we must have objected because of the direct connection to surface waters. Rick Baker claims he then talked with you about demonstrating low density by eliminating the existing BUA from the calculation, and that no mention of a pocket of high density was made. The problem is the existing BUA was replaced, almost on a 1:1 basis, by new BUA, so that method cannot be used. Had the existing BUA remained on site and new BUA added to the site, (not replacing the existing) then that method of calculating density could have been used. Do you recall anything about agreeing to allow them to submit under low density with no treatment for the pocket of high density? I found your file on the Marina and the plans you originally looked at, which do not differ from the ones they propose today, but there were no other notes about the project. I told them I can't prove or disprove whether or not they knew about the pocket of high density. Although I believe you, I can't prove it because it's not written in any correspondence or meeting notes. If you have copies of any old correspondence or phone conversations, or emails regarding the meetings and what was decided, it would be most helpful. also told them I am going by what I see, since I am the reviewer and I have to write the permit, and I see a pocket of high density.

Austin. He is doing great. It took about a month for him to recover fully from the surgery. For all purposes he appears to be a normal healthy four year all for the exception of the 6 in. scar on the back of his head. He started a Pre-K program back in the middle of August and is adjusting to public school as well as one could expect. I hope you got my voice mail earlier today, S wasn't sure if I could get my computer back up and running today so I called. As far as Cape Lookout is concerned, I know we always considered the project as a pocket of HD. Even during the later discussions in Oct. 2000, we discussed the likely hood of not being able to use the wetland as a treatment device for two main reasons: first we didn't want to start precedence and thereby opening the door for everyone to build on their uplands and just using the lowlands to "treat" the stormwater; second and probably more important for this particular project.was that the wetlands were tidally influenced. (Ask Joanne S. about this, I'm sure she remembers.) What kind of treatment could we get with the tide constantly affecting the water levels, i.e. flushing out sediment directly into the receiving water body. (Core Sound?) From the start I believe an infiltration system was going to be required to pick up the HD pocket. I also believe we ran into a problem with the SHWT being too high to meet any separation. I, like Jeanette, would like to know how in the world they were able to get permission to dredge? As far as T remember no reasonable solution was meet regarding SW because the biggest holdback to the project was the dredging. However, I do remember when I met with Gene Cobb and Rick Baker the last time they didn't have a solution that was acceptable(SHWT). I hope this helps, and please call if I can help any further with this or any other project. Scott P.S. let me know how this project turns out Linda Lewis wrote: > Scott and Jeanette: > Hey you two!!

I recommend scheduling the meeting independent of the staff` meeting unless you can wait till December. I've c-mailed John Dorney to see who he wants on it and he'd like Steve Kroeger (733-9604) and Todd St. John (733-9584) to be there. John may sit in if he can. Joanne would be a good one to have, as Scott mentioned, so you should try to get tier on board if she can make it. The schedule of days I am not available to meet include Oct. 5-13, 19, and 24-27. Just let me know when you have something set up. Probably easiest to have Todd or Steve schedule the conference room at the lab. Thanks, JP Rick Baker wrote: Jeanette, I spoke with Scott Vinson on Friday of last week about this project and meeting with him and someone from the wetlands unit and possibly you to discuss a more detailed approach to stormwater management. Scott agreed this would be a good idea. Whom would you recommend I contact from Wetlands unit? I asked Scott about possibly meeting the same day you guys have the monthly stormwater meeting in Raleigh. Fie thought that could be worked out but he did not know the date of the next meeting. I was assuming Oct 3. Please confirm this date. Would you be available that day and/or do you wish to attend this meeting? Scott mentioned Joanne Steinhuis may want to be involved. Any thoughts?

Briefly, our client is proposing to construct a marina on the north side of Harker's Island on Eastmouth Bay. The site has an existing canal into the property with a portion of the site classified as wetlands that were created by digging "mosquito ditches" years ago. We are proposing to have a meeting with all of you and possibly John Dorney to review a possible stormwater management system that will utilize BMP's and discharge into the existing wetlands. In this meeting, I would hope to accomplish determining a direction of design that would probably get approved. Obviously, approval cannot be promised since design has not been submitted, but this discussion can help us reach a solution that works and is permittable. I wanted to see if Oct 16, 17, 20 or 23 would work with your schedules with the meeting preferably in Raleigh. Please review your calendar and let me know which of these days work.

As promised, please find attached two photographs showing the proposed marina site and a survey showing the existing impervious area that has been on site since at least November 1989. This existing impervious area covers 1.07 ac. Please note on the photographs the wetlands on site were created by digging "mosquito" ditches at some point in the past and are not pristine wetlands. As requested, I will call you the morning of June 19 to remind you to have a brief meeting with Linda Lewis to answer the questions we discussed including, the 30' buffer and waters of the State, low density versus high density, existing impervious area and use of the existing wetlands as stormwater treatment and other relevant items.

Cape Lookout Marina, Inc. 3315 Old Forrest Road Lynchburg, VA 24501 Subject: Request for Additional Information Stormwater Project No. SW8 n/a Cape Lookout Marina Carteret County Dear Mr. Richards: The Wilmington Regional Office received a Stormwater Management Permit Application for Cape Lookout Marina on August 19, 2003. A preliminary review of that information has determined that the application is not complete. The following information -is needed to continue the stormwater review: 1. Please add the nearest intersection of two major roads to the vicinity map. A major road is any 1, 2 or 3 digit NC, US or interstate highway. 2. Please report all built -upon areas in square feet on the application. 3. Please provide a signed and notarized Operation and Maintenance plan in accord with Chapter 3.3 of the BMP Manual. In addition, monthly inspections are required. 4. Please submit detailed design calculations for each sand filter. I am unable to determine how you arrived at the provided surface areas and volumes, based on the dimensions of the systems. Include a calculation of the required orifice sizing as well. Design requirements are outlined in Chapter 3 of the BMP Manual. 5. The rules require that only the president or vice-president of a corporation may sign the application. The engineer or an agent may sign only if accompanied by a letter of authorization from the president or vice president. 6. Please provide sufficient spot elevations for the double -bay parking areas on the west side. Sheet flow is required for these areas as well as for the single -bay parking down the west side. From the grades shown, it appears that runoff will be channeled in the middle. 7. There are two different sandfilters specified, one is precast, and. one will be built in place. Which of the 3 proposed sandfilters is precast? If filters 2 and 3 will be precast, please indicate this on the precast detail. AV *A G.
