Wedgefield at Crosswinds South Subdivision South College Road and Wedgefield Drive, Wilmington, New Hanover County FOR THE construction of built -upon areas with runoff to be treated in one (1) onsite wet detention pond (the "Front Pond') operated and maintained by Wedgefield at Crosswinds South HOA, Inc.(hereafter "Wedgefield" or "the permittee'); and for the construction of built -upon areas with runoff to be treated in an offsite wet detention pond (the "Rear Pond'), operated and maintained by Crosswinds HOA, Inc., under the terms and conditions set forth in the latest version of Permit No. SW8 930710; in compliance with the provisions of 15A NCAC 2H.1000 (hereafter referred to as the "stormwater rules'), and in accordance with the June 5, 2007, Consent Judgment, and the approved stormwater management plans and specifications and other supporting documentation as attached and on file with and approved by the Division and considered an enforceable part of this permit. The terms and conditions of this permit shall survive the dissolution of the Consent Judgment. This permit shall be effective from the date of issuance until May 22, 2022, and shall be subject to the following specified conditions and limitations: I. DESIGN STANDARDS This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data. The overall tract built -upon area percentage for the project must be maintained at or below 30% per the requirements of Section .1005 of the stormwater rules. The subdivision is permitted for 76 lots, each limited to a maximum amount of built -upon area (BUA). Lots 1-37 shown on the April 29, 1993 approved plans for SW8 921115 are limited to a maximum BUA of 4,500 square feet each. Lots 201-239 shown on the May 8, 1996 approved plans for SW8 960317 are limited to a maximum BUA of 4.300 square feet each. 3. The built -upon area allocated for Wedgefield that will be treated by the offsite Crosswinds "Rear Pond" under Stormwater Management Permit No. SW8 930710, is 373,376 square feet. 4. This permit allows for the treatment of runoff from the built -upon areas of this subdivision in two (2) different permitted Stormwater Control Measures (SCM). Section 1.7 of this permit describes the design parameters of the permitted onsite wet detention pond. The design parameters of the offsite wet detention pond are described in permit number SW8 930710. issued to Crosswinds HOA, Inc. The approved plans contain a "drainage area map" which shows the specific drainage area of Wedgefield at Crosswinds South Subdivision to each pond. Page 1 of 5 • State Stormwater Management Systems Permit No. SW8 921115 A This permit covers the original 37 lots permitted as Crosswinds South under SW8 921115 and the 39-lot extension permitted as Wedgefield at Crosswinds South under SW8 960317. This permit combines and consolidates the referenced permits into one permit under SW8 921115, combines the approved plan sets into one approved plan set under SW8 921115, and rescinds SW8 960317. For purposes of this permit, all 76 lots are considered as part of the project called "Wedgefield at Crosswinds South". The runoff from 16 of the original 37 Crosswinds South lots and a portion of the road is treated in the onsite "Front Pond". The runoff from the remaining 21 Crosswinds South lots and road and all 39 Wedgefield at Crosswinds South lots is to be directed to and treated by the offsite Crosswinds Pond (the "Rear Pond"). Approved plans, specifications and mutual agreements between the permittee and the Division for this project, are incorporated by reference and are enforceable parts of the permit. The following design elements have been permitted for the onsite wet detention pond stormwater facility, a.k.a. the Front Pond, and must be provided in the system at all times. These design elements are consistent with the terms of the Consent Judgment. a. Drainage Area, acres: Onsite, acres: Offsite, acres: b. Total Impervious Surfaces, ft2: Road, ft2: Offsite, ft2: C.

The road ditch in the NC 132 Highway right-of-way (South College Road) receives the pond's pumped volume and is considered as the required vegetated filter. II. SCHEDULE OF COMPLIANCE No person or entity shall fill in, alter, or pipe any drainage feature (such as swales), shown on the approved plans as part of the stormwater management system, unless and until a revision to the permit is submitted to and approved by the Division. 2. All of the lots in the subdivision are built on. The permittee shall not be held responsible for existing built -upon area overages on the lots. However, the permittee shall make ongoing efforts as time and finances allow, to identify and document all such overages on the lots. The Division may or may not take action against the individual lot owners for those overages. 3. From the issue date of this permit forward, the permittee shall monitor the project on a routine basis to ensure that all lots maintain compliance with the maximum permitted built -upon area limit for that lot. Due to construction which deviates from the April 29, 1993 approved plans, neither the Wedgefield Front Pond nor the Crosswinds Rear Pond has a sufficient amount of surface area or depth to justify any increases in the maximum allowed per lot built -upon area. Page 2 of 5 State Stormwater Management Systems Permit No. SW8 921115 The permittee shall review all proposed modifications and additions to the existing lots within the Wedgefield at Crosswinds South Subdivision for compliance with the built - upon area limit. The permittee shall not approve any proposed lot plan additions or modifications if the lot is already over the maximum BUA limit, or if such additional construction will cause the lot to exceed the maximum BUA limit established by this permit. The permittee shall notify the Division and shall take such measures as are allowed by the Declaration of Covenants and Restrictions or by law to prevent the lot owner from constructing any such non -compliant improvements and modifications. Any approvals granted by the permittee for any lot addition or modification that results in an overage of the permitted maximum BUA for that lot, will require that the permittee submit a modification to this permit and propose the necessary improvements such that the permitted SCM meets the current stormwater rules. 5. The Division will take no action against the permittee for existing non -compliances, as identified in the Consent Judgment which is attached hereto and made an enforceable part of this permit, which are a part of or caused by the original construction, including the deficient permanent pool surface area in the pond. From May 22, 2014 forward, the Director may notify the permittee when the permitted site does not meet one or more of the minimum requirements of the modified 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. 6. The runoff from all built -upon area in Wedgefield that is within the permitted drainage area boundary of either the onsite Front Pond or the offsite Rear Pond must be collected and directed into the appropriate stormwater pond. 7. All stormwater collection and treatment systems must be located in either dedicated common areas or recorded easements. The final plats for the project have been recorded showing all such required easements, in accordance with the approved plans. 8. 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. Further subdivision, acquisition, or sale of any part or all of the project area. C. The addition of built -upon that is in excess of the permitted maximum for that pond. d. Alteration of any pipe or vegetative conveyance shown within the permit boundary on the approved plan. Routine maintenance such as sediment removal and mowing, removal of obstructions within the pipes and/or replacement of any damaged pipes do not require a permit modification. e. The construction of any areas of #57 stone or permeable pavement or certain landscape materials, for BUA credit. f. Any other revision as determined by the Director. At no time shall the permittee be required to perform any work that is contrary to the terms of the original Consent Judgment. 9. The permittee shall at all times follow the approved Operation and Maintenance Agreement and provide the operation and maintenance necessary to assure that all components of the permitted stormwater system function at design condition. The approved Operation and Maintenance Agreement outlines the necessary maintenance items and required maintenance intervals. The on -site runoff collection system of catch basins, piping, ditches and swales must also be maintained such that the one (1) inch runoff volume is adequately conveyed to the approved BMP(s). 10. Records of maintenance activities must be kept and made available upon request to authorized personnel of DEQ. The records will indicate the date, activity, name of person performing the work and what actions were taken. Page 3 of 5 State Stormwater Management Systems Permit No. SW8 921115 11. The permittee shall assure that permanent access to the permitted SCM components, including the collection system, is provided via recorded easements, common areas or public rights -of -way. All such easements, common areas and rights -of -way currently appear on the recorded plats. 12. Deed restrictions limiting the amount of built -upon area on each lot have been recorded and currently provide that the maximum built -upon area per lot is as follows: Lots 1-37 @4,500 square feet and Lots 201-239 @4,300 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. 13. The State of North Carolina is made a third -party beneficiary of the covenants to the extent necessary to maintain compliance with this Stormwater Management Permit. 14. The Declaration of Restrictions and Protective Covenants are to run with the land and be binding on all persons and parties claiming under them. 15, The recorded covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Energy, Mineral and Land Resources. 16. Permanent seeding requirements for the stormwater control must follow the guidelines established in the North Carolina Erosion and Sediment Control Planning and Design Manual. These guidelines assist in the selection of a suitable grass type that will perform the best for a particular use, the best planting time, soil amendments, fertilizer needs, mulch and watering. 17. The project and the SCM shall be constructed, operated and maintained in accordance with the conditions of the Consent Judgment, the conditions of this permit, the approved plans and specifications, and other supporting data. III. GENERAL CONDITIONS Wedgefield shall not be required to restore the slope on the west bank of the front pond to a 3:1 ratio. The Division shall, to the extent required by the North Carolina General Statutes and any rules promulgated there under authorize, grant and provide any and all necessary permits required for Wedgefield, at no cost to perform the activities which are referenced herein and agreed upon by the parties. All activities undertaken pursuant to the Consent Judgment are deemed by agreement of the parties to be maintenance which will not require the application for, or issuance of, any new permits. 3. Wedgefield is required to operate and maintain the Front Pond in compliance with the provisions of this permit. 4. Any individual or entity found to be in noncompliance with the terms, conditions and limitations of a stormwater permit or the stormwater rules, is subject to enforcement action in accordance with the provisions of North Carolina General Statute 143, Article 21. 5. The issuance of this permit does not preclude the Permittee from complying with any and all statutes, rules, regulations, or ordinances, which may be imposed by other government agencies (local, state, and federal), which have jurisdiction.

Attn: Koreen La Rose, President 4604 Wedgefield Drive Wilmington, NC 28409 NORTH CAROLINA Environmental Quality Subject: Request for Additional Information Stormwater Project No. SW8 921115 Wedgefield Subdivision New Hanover County Dear Ms. La Rose: The Wilmington Regional Office met with you and Ms. Orseno on June 24, 2019, to discuss the additional information requested on June 18, 2019 for the subject State Stormwater Management Permit. To recap our conversation, a survey of the pond area had been done by a licensed surveyor on February 25, 2015, after the HOA completed restoration efforts. The surveyor extrapolated the surface areas and calculated a volume. However, DEMLR was unable to accept this type of calculation from a surveyor and required that it be stamped by a PE. The HOA then hired Larry Sneeden, who provided additional calculations in 2016 which were never completed. As I understand our conversation, the HOA would like for the current consultant (Lloyd Tyndall, P.E.) to utilize the existing 2015 survey information to build on the calculations that Mr. Sneeden already started, to complete this application. The Division has no objection to this as everything to date has been completed by either a licensed professional surveyor or a licensed professional engineer. As requested by the HOA, I offer the following summary of the 2015 survey and the 2016 calculations for Mr. Tyndall's consideration: 1. NAVD29 VS. NAVD88. The HOA would like to keep the NAVD88 survey datum as noted on the February 2015 survey signed and sealed by Vernon Derek Danforth, PLS. 2. TEMPORARY POOL ELEVATION. The 2015 survey indicates that the invert of the 18" pipe leaving the outlet structure is 22.2. This is the controlling elevation and will by default, be the new temporary pool elevation. 3. BOTTOM ELEVATION. Based on the 2015 survey, the bottom elevation of the pond appears to be 16.0. 4. PERMANENT POOL ELEVATION. This elevation, by default, will be the elevation at which the float switch in the pump station switches off. The design depth of the pond is 5 feet, so the permanent pool elevation cannot be lower than 21. Mr. Sneeden's calculations had proposed 21.45 as the permanent pool elevation. Per the 2015 survey information, the bottom of the small weir at the base of the outlet structure is at 21.45. If 21.45 is to be the new permanent pool elevation, the float switch for the pump "off" elevation must be reset.

SURFACE AREAS AND STORAGE VOLUME. The following surface areas were extrapolated from the 2015 survey as indicated in the table below. The incremental volume reported in the 2016 calculations (750 sf) was incorrect. Based on the average area method ((12400 + 13400)/2) X (22.2 - 21.45), this design provides approximately 9,675 cubic feet of storage volume between the temporary pool elevation and the permanent pool elevation. ElevationI Area Incremental Volume 21.45(permanentpool) 12,400 sf 22.2 tem ora ool 13,400 sf 9675 cf @22.2 These five areas cover the extent of the missing information that is needed to complete the review and issue the permit. All of this information is readily available in the existing documents that the HOA provided to the consultant. Please respond to this request for additional information by August 8, 2019, which provides 30 days of time after the consultant gets back from vacation on July 8, 2019. If additional time is needed to submit the requested information please e-mail, mail, or fax your extension request, prior to the original due date, to the Division using the contact information available in this letter. The extension request must include a justification and a date of when the requested information will be submitted to the Division. Please remember that extension requests delay the issuance of the final permit. The Division is allowed 90 days from the receipt of a complete application to issue the permit.

DANIEL SMITH Director June 18, 2019 NORTH CAROLINA Environmental Quality Wedgefield Homeowners Association, Inc. Attn: Koreen LaRose or current president (via email: 4604 Wedgefield Drive Wilmington, NC 28409 Subject: Request for Additional Information Stormwater Project No. SW8 921115 Wedgefield Subdivision New Hanover County Dear Ms. LaRose or current president: The Wilmington Regional Office received the additional information regarding the subject existing State Stormwater Management Permit on April 17, 2019. A preliminary review of that information has determined that the application is not complete and that additional information is needed. To continue the review, please provide the following additional information: 1. Are you changing the permanent pool or design pool elevations? The original permitted plan details have the Normal Water Level at elevation 22 and the design storage elevation at 23.3. The revised calculations start at elevation 21 and go all the way up to elevation 25.1. The storage volume that goes into the permit is going to be that volume provided between the set permanent pool elevation and the temporary pool elevation and need only be sufficient to accommodate the runoff from the first inch of rain within the 5.66 acre drainage area. We would like to get at least 20,545 cf of storage between elevations 22 and 23.3. As indicated in the Consent Judgment, this may or may not be possible due to the lack of available space. 2. Using the surface areas provided in the revised calculations, and assuming that the permanent pool (22) and temporary pool (23.3) elevations as indicated in the permit are unchanged, I checked the volume provided between elevations 22 and 23.3 and came up with 36,265 cf. If the permanent pool and/or the temporary pool elevations have changed, then I need to know what the new permanent pool elevation is and what the new temporary storage elevation is. New outlet structure details would also have to be provided. 3. The Lidar survey provided by Mr. Tyndall appears to suggest that all of the pond's surface areas from elevation 21 to elevation 25 extend up into the 4 lots that back up to this pond (lots 34-37). Based on Google and past observations, the pond itself is supposed to be confined to that triangular -shaped space behind those 4 lots and does not extend that far up into the lots. Most of those lots have fences installed at or very near the top of the bank. Unless the houses on those 4 lots have been removed, this survey does not appear to reflect the true as -built location of the pond. 4. The lowest contour elevation on the Lidar survey is 21 with the bottom of the pond noted as 20.8. Per the approved plans, the bottom elevation of this pond should be 17. When was the sediment level checked? The accumulated sediment will need to be removed. Please respond to this request for additional information by July 18, 2019. Mr. Tyndall did not provide an email address, so this letter will be mailed to him. Please remember to confirm that any revised information is presented consistently throughout the application documents including calculations, supplements, narrative, and plans. Please also remember to provide two hard copies of any updated documents per 15A NCAC 02H.1042(2).

IT IS TO FURTHER CERTIFY THAT THE ATTACHED TECHNICAL DATA SUPPORTS THE FACT THAT THE EXISTING CONSTRUCTION/INSTALLATION OF STORAGE AREAS/PUMPS/CONCRETE INLET & SPILLWAY/CORRUGATED METAL PIPE SPILLWAY AND MAINTENANCE OF THE FACILITY MEETS THE "1.0" RUNOFF/ STORAGE STANDARD" AND ALSO MEETS THE "1.5" RUNOFF/ STORAGE STANDARD" BASED ON TOPOGRAPHIC MAP WITH SPOT SHOTS BASED ON SPATE OF NORTH CAROLINA's LIDAR SURVEY AND PHYSICAL MEASUREMENTS AT THE SITE. EVEN THOUGH THE SITE WAS ORIGINALLY DESIGNED 'TO MEET THE "1.0" RUNOFF/STORAGE STANDARD" IT SHOULD BE NOTED THAT AFTER "HURRICANE FLORENCE—WITH 30 INCHES RAINFALL AND ESTIMATED IN EXCESS OF 24 INCHES RUNOFF —THE HURRICANE FLORENCE HIGH WATER MARK AT THE "FRONT POND" WAS ELEV. 24.2' WHICH IS ABOUT THE SAME AS THE "1.5" THEORETICAL DESIGN. THE WEDGEFIELD HOMEOWNERS ASSOCIATION HAS INSTALLED AND MAINTAINED A FACILITY SUCH THAT NO REPORTED "FLOODING OF HOMES OCCURRED INSIDE THE WEDGEFIELD HOMEOWNERS ASSOCIATION TERRITORY DURING THE. HURRICANE FLORENCE—THEREFORE THE ONLY CONCLUSION I CAN MAKE IS THAT 'PHIS CONSTRUCTION/INSTALLATION OF STORAGE AREAS/CONCRETE INTAKE & SPILLW'A%', PUMPS /CORRUGATED METAL PIPE SPILLWAY AND MAINTENANCE OF THE FACILITY MEETS THE "1.0" RUNOFF AND THE 1.5" RUNOFF STORAGE REQUIREMENTS.

SCHEDULE OF COMPLIANCE 1. The permittee shall obtain an estimate of the depth of the accumulated sediment in the pond. If the sediment has accumulated to a point such that the pond depth is four feet or less, the permittee shall enter into an agreement with DEMLR regarding the time frame for removing the accumulated sediment such that the pond's design depth is restored to 5 feet. Along with or subsequent to the removal of the accumulated sediment, the permittee shall enter into an agreement with the Division to stabilize the side slopes of the Front Pond as per the Consent Judgment, and to provide as much permanent pool surface area as reasonably possible, given the physical constraints. The permittee shall then submit a permit modification and revised plans to the Division reflecting the permanent pool surface area and temporary pool storage volume that have been. provided. 2. No person or entity shall fill in, alter, or pipe any drainage feature (such as swales), shown on the approved plans as part of the stormwater management system, unless and until a revision to the permit is submitted to and approved by the Division. 3. i4Jl of the lots in the subdivision are built ort, The permittee shall not be held responsi6fe o er xisfmg ui -upon area overages on the lots. However, the permittee shall make ongoing efforts as time and finances allow, to identify and document all such overages on the lots. The Division may or may not take action against the individual lot owners for those overages. 4. From the issue date of this permit forward, the permittee shall monitor the project on a routine basis to ensure that all lots maintain compliance with the maximum permitted built -upon area limit for that lot. Due to construction which deviates from the April 29, 1993 approved plans, neither the Wedgefield Front Pond nor the Crosswinds Rear Pond has a sufficient amount of surface area to justify any increases in the maximum allowed per lot built -upon area. 5. From the issue date of this permit forward, the permittee shall review all proposed modifications and additions to the existing lots within the Wedgefield at Crosswinds South Subdivision for compliance with the built -upon area limit. The permittee shall not approve any proposed lot plan additions or modifications if the maximum BUA limit established by this permit for that lot is exceeded. The permifee shall notify the Division and shall take such measures as are allowed by the Declaration of Covenants and Restrictions or by law to prevent the lot owner from constructing such non -compliant improvements and modifications. Any approvals granted by the permittee for any lot addition or modification that results in an overage of the permitted maximum BUA for that lot, will require that the permittee submit a modification to this permit and propose the necessary Improvements such that the permitted BMP meets the current stormwater rules. 6. The Division will take no action against the permittee for existing non - compliances, as identified in the Consent Judgment which is attached hereto and made an enforceable part of this permit, which are a part of or caused by the original construction, including the deficient permanent pool surface area in the pond. From the issue date of this permit forward, the Director may notify the permittee when the permitted site does not meet one or more of the minimum requirements of the modified 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.

Any revision to the approved plans, regardless of size. b. Further subdivision, acquisition, or sale of any part or all of the project area. C. The addition of built -upon that is in excess of the permitted maximum for that pond. C. Alteration of any pipe or vegetative conveyance shown within the permit boundary on the approved plan. Routine maintenance such as sediment removal and mowing, removal of obstructions within the pipes and/or replacement of any damaged pipes do not require a permit modification. 10. The Director may determine that other revisions to the project should require a modification to the permit. At no time shall the permittee be required to perform any work that is contrary to the terms of the Consent Judgment, which is attached hereto and made an enforceable part of this permit. 11. All stormwater collection and treatment systems must be located in either dedicated common areas or recorded easements. The final plats for the project have been recorded showing all such required easements, in accordance with the approved plans. 12. Following notification to DEMLR that the approved modifications to the BMP have been completed as per the terms of a future agreement between DEMLR and the permittee, the permittee shall submit a certification from an appropriate designer for the system installed certifyingthat this facility has been restored per the approved plans and per the terms of the agreement reached between the permittee and the Division. 13. The permittee shall at all times follow the approved Operation and Maintenance Agreement and provide the operation and maintenance necessary to assure that all components of the permitted stormwater system function at design condition. The approved Operation and Maintenance Agreement outlines the necessary maintenance items and required maintenance intervals. The on -site runoff collection system of catch basins, piping, ditches and swales must also be maintained such that the one (1) inch runoff volume is adequately conveyed to the approved BMP(s). 14. Records of maintenance activities must be kept and made available upon request to authorized personnel of DENR. The records will indicate the date, activity, name of person performing the work and what actions were taken. 15. The permittee shall assure that permanent access to the permitted BMP components, including the collection system, is provided via recorded easements, common areas or public rights -of -way. All such easements, common areas and rights -of -way currently appear on the recorded plats. Fr`aa /GI,r Page 6 of 11 State Stormwater Management Systems Permit No. SW8 921115 16.

IT IS TO FURTHER CERTIFY THAT THE ATTACHED TECHNICAL DATA SUPPORTS THE FACT THAT THE EXISTING CONSTRUCTION/INSTALLATION OF STORAGE AREAS/PUMPS/CONCRETE INLET & SPILLWAY/CORRUGATED METAL PIPE SPILLWAY AND MAINTENANCE OF THE FACILITY MEETS THE "1.0" RUNOFF/ STORAGE STANDARD" AND ALSO MEETS THE "1.5" RUNOFF/ STORAGE STANDARD" BASED ON TOPOGRAPHIC MAP WITH SPOT SHOTS BASED ON STATE OF NORTH CAROLINA's LIDAR SURVEY AND PHYSICAL MEASUREMENTS AT THE SITE. EVEN THOUGH THE SITE WAS ORIGINALLY DESIGNED TO MEET THE "1.0" RUNOFF/STORAGE STANDARD" IT SHOULD BE NOTED THAT AFTER "HURRICANE FLORENCE—WITH 30 INCHES RAINFALL AND ESTIMATED IN EXCESS OF 24 INCHES RUNOFF —THE HURRICANE FLORENCE HIGH WATER MARK AT THE "FRONT POND" WAS ELEV. 24.2' WHICH IS ABOUT THE SAME AS THE "1.5" THEORETICAL DESIGN. THE WEDGEFIELD HOMEOWNERS ASSOCIATION HAS INSTALLED AND MAINTAINED A FACILITY SUCH THAT NO REPORTED "FLOODING OF HOMES OCCURRED INSIDE THE WEDGEFIELD HOMEOWNERS ASSOCIATION TERRITORY DURING THE HURRICANE FLORENCE—THEREFORE THE ONLY CONCLUSION I CAN MAKE IS THAT THIS CONSTRUCTION/INSTALLATION OF STORAGE AREAS/CONCRETE INTAKE & SPILLWAY, PUMPS /CORRUGATED METAL PIPE SPILLWAY AND MAINTENANCE OF THE FACILITY MEETS THE "1.0" RUNOFF AND THE 1.5" RUNOFF STORAGE REQUIREMENTS.

If the sediment has accumulated to a point such that the pond depth is four feet or less, the permittee shall enter into an agreement with DEMLR regarding the time frame for removing the accumulated sediment such that the A pond's design depth is restored to 5 feet. Along with or subsequent to they removal of the Sccumulated sediment, the permittee shall enter into an �eSi�u agreement with the Division to stabilize the side slopes of the Front Pond as per the Consent Judgment, to and provide as much permanent pool surface area as reasonably possible, given the physical constraints. The permittee shall then submit a permit modification and revised plans to the Division reflecting the permanent pool surface area and temporary pool storage volume that have been provided. 2. No person or entity shall fill in, alter, or pipe any drainage feature (such as swales), shown on the approved plans as part of the stormwater management system, unless and until a revision to the permit is submitted to and approved by the Division. 3. `All of the lots in the subdivision are built on The permittee shall not be held response a or existing ui -upon area overages on the lots. However, the permittee shall make ongoing efforts as time and finances allow, to identify and document all such overages on the lots. The Division may or may not take action against the individual lot owners for those overages. 4. From the issue date of this permit forward, the permittee shall monitor the project on a routine basis to ensure that all lots maintain compliance with the maximum permitted built -upon area limit for that lot. Due to construction which deviates from the April 29, 1993 approved plans, neither the Wedgefield Front Pond nor the Crosswinds Rear Pond has a sufficient amount of surface area to justify any increases in the maximum allowed per lot built -upon area. 5. From the issue date of this permit forward, the permittee shall review all proposed modifications and additions to the existing lots within the Wedgefield at Crosswinds South Subdivision for compliance with the built -upon area limit. The permittee shall not approve any proposed lot plan additions or modifications if the maximum BUA limit established by this permit for that lot is exceeded. The permittee shall notify the Division and shall take such measures as are allowed by the Declaration of Covenants and Restrictions or by law to prevent the lot owner from constructing such non -compliant improvements and modifications. Any approvals granted by the permittee for any lot addition or modification that results in an overage of the permitted maximum BUA for that lot, will require that the permittee submit a modification to this permit and propose the necessary Improvements such that the permitted BMP meets the current stornwater rules. 6. The Division will take no action against the permittee for existing non - compliances, as identified in the Consent Judgment which is attached hereto and made an enforceable part of this permit, which are a part of or caused by the original construction, including the deficient permanent pool surface area in the pond. From the issue date of this permit forward, the Director may notify the permittee when the permitted site does not meet one or more of the minimum requirements of the modified 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. Page 5 of 11 State Stonmwater.

The addition of built -upon that is in excess of the permitted maximum for that pond. C. Alteration of any pipe or vegetative conveyance shown within the permit boundary on the approved plan. Routine maintenance such as sediment removal and mowing, removal of obstructions within the pipes and/or replacement of any damaged pipes do not require a permit modification. 10. The Director may determine that other revisions to the project should require a modification to the permit. At no time shall the permittee be required to perform any work that is contrary to the terms of the Consent Judgment, which is attached hereto and made an enforceable part of this permit. 11. All stormwater collection and treatment systems must be located in either dedicated common areas or recorded easements. The final plats for the project have been recorded showing all such required easements, in accordance with the approved plans. 12. Following notification to DEMLR that the approved modifications to the BMP have been completed as per the terms of a future agreement between DEMLR and the permittee, the permittee shall submit a certification from an appropriate designer for the.system installed certifying that this facility has been restored per the approved plans and per the terms of the agreement reached between the permittee and the Division. 13. The permittee shall at all times follow the approved Operation and Maintenance Agreement and provide the operation and maintenance necessary to assure that all components of the permitted stormwater system function at design condition. The approved Operation and Maintenance Agreement outlines the necessary maintenance items and required maintenance intervals. The on -site runoff collection system of catch basins, piping, ditches and swales must also be maintained such that the one (1) inch runoff volume is adequately conveyed to the approved BMP(s). 14. Records of maintenance activities must be kept and made available upon request to authorized personnel of DENR. The records will indicate the date, activity, name of person performing the work and what actions were taken. 15. The permittee shall assure that permanent access to the permitted BMP components, including the collection system, is provided via recorded easements, common areas or public rights -of -way. All such easements, common areas and rights -of -way currently appear on the recorded plats. Page 6 of 11 State Stommater Management Systems Permit No. SW8 921115 16. Each lot is, limited to a maximum amount of built -upon area as specified below. Deed restrictions limiting the amount of built -upon area on each lot have been, recorded and currently provide that the maximum built -upon area per lot is as follows: Lots 1-37 @4,500 square feet and Lots 201-239 ®4,300 square feet, I 11 evdoff This allotted amount includes any built -upon area constructed within the lot t , 013p,if property boundaries, and that portion of the right-of-way between the front lot line and the edge of the pavement.

IT IS TO FURTHER CERTIFY THAT THE ATTACHED TECHNICAL DATA SUPPORTS THE FACT THAT THE EXISTING CONSTRUCTION/INSTALLATION OF STORAGE AREAS/PUMPS/CONCRETE INLET & SPILLWAY/CORRUGATED METAL PIPE SPILLWAY AND MAINTENANCE OF THE FACILITY MEETS THE "1.0" RUNOFF/ STORAGE STANDARD" AND ALSO MEETS THE "1.5" RUNOFF/ STORAGE STANDARD" BASED ON TOPOGRAPHIC MAP WITH SPOT SHOTS BASED ON STATE OF NORTH CAROLINA'S LIDAR .SURVEY AND PHYSICAL MEASUREMENTS AT THE SITE. EVEN THOUGH THE SITE WAS ORIGINALLY DESIGNED TO MEET THE "1.0" RUNOFF/STORAGE STANDARD" IT SHOULD BE NOTED THAT AFTER "HURRICANE FLORENCE-WITH 30 INCHES RAINFALL AND ESTIMATED IN EXCESS OF 24 INCHES RUNOFF -THE HURRICANE FLORENCE HIGH WATER MARK AT THE "FRONT POND" WAS ELEV. 24.2' WHICH IS ABOUT THE SAME AS THE "1.5" THEORETICAL DESIGN. THE WEDGEFIELD HOMEOWNERS ASSOCIATION HAS INSTALLED AND MAINTAINED A FACILITY SUCH THAT NO REPORTED "FLOODING OF HOMES OCCURRED INSIDE THE WEDGEFIELD HOMEOWNERS ASSOCIATION TERRITORY DURING THE HURRICANE FLORENCE-THEREFORE THE ONLY CONCLUSION I CAN MAKE IS THAT THIS CONSTRUCTION/INSTALLATION OF STORAGE AREAS/CONCRETE INTAKE & SPILLWAY, PUMPS /CORRUGATED METAL, PIPE SPILLWAY AND MAINTENANCE OF THE FACILITY MEETS THE "1.0" RUNOFF AND THE 1.5" RUNOFF STORAGE REQUIREMENTS.

If the sediment has accumulated to a point such that the pond depth is four feet or less, the permittee shall enter into an agreement with DEMLR regarding the time frame for removing the accumulated sediment such that the ,1 pond's design depth is restored to 5 feet. Along with or subsequent to the ww removal of the accumulated sediment, the permittee shall enter into an agreement with the Division to stabilize the side slopes of the Front Pond as per the Consent Judgment, and to provide as much permanent pool surface area as reasonably possible, given the physical constraints. The permittee shall then submit a permit modification and revised plans to the Division reflecting the permanent pool surface area and temporary pool storage volume that have been provided. 2. No person or entity shall fill in, alter, or pipe any drainage feature (such as swales), shown on the approved plans as part of the stormwater management system, unless and until a revision to the permit is submitted to and approved by the Division. It 3. `All of the lots in the subdivision are built on. -The permittee shall not be held Ili :sponsibrfor exisfing w -upon area overages on the lots. However, the permittee shall make ongoing efforts as time and finances allow, to identify and document all such overages on the lots. The Division may or may not take action against the individual lot owners for those overages. 4. From the issue date of this permit forward, the permittee shall monitor the project on a routine basis to ensure that all lots maintain compliance with the maximum permitted built -upon area limit for that lot. Due to construction which deviates from the April 29, 1993 approved plans, neither the Wedgefield Front Pond nor the Crosswinds Rear Pond has a sufficient amount of surface area to justify any increases in the maximum allowed per lot built -upon area. 5. From the issue date of this permit forward, the permittee shall review all proposed modifications and additions to the existing lots within the Wedgefield at Crosswinds South Subdivision for compliance with the built -upon area limit. The perrniltee shall not approve any proposed lot plan additions or modifications if the maximum BUA limit established by this permit for that lot is exceeded. The permittee shall notify the Division and shall take such measures as are allowed by the Declaration of Covenants and Restrictions or by law to prevent the lot owner from constructing such non -compliant improvements and modifications. Any approvals granted by the permittee for any lot addition or modification that results in an overage of the permitted maximum BUA for that lot, will require that the penmittee submit a modification to this permit and propose the necessary Improvements such that the permitted BM meets the current stonmwater rules. 6. The Division will take no action against the permittee for existing non - compliances, as identified in the Consent Judgment which is attached hereto and made an enforceable part of this permit, which are a part of or caused by the original construction, including the deficient permanent pool surface area in the pond. From the issue date of this permit forward, the Director may notify the permittee when the permitted site does not meet one or more of the minimum requirements of the modified 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.

Any revision to the approved plans, regardless of size. b.. Further subdivision, acquisition, or sale of any part or all of the project area. C. The addition of built -upon that is in excess of the permitted maximum for that pond. C. Alteration of any pipe or vegetative conveyance shown within the permit boundary on the approved plan. Routine maintenance such as sediment removal and mowing, removal of obstructions within the pipes and/or replacement of any damaged pipes do not require a permit modification. 10. The Director may determine that other revisions to the project should require a modification to the permit. At no time shall the permittee be required to perform any work that is contrary to the terms of the Consent Judgment, which is attached hereto and made an enforceable part of this permit. 11. All stormwater collection and treatment systems must be located in either dedicated common areas or recorded easements. The final plats for the project have been recorded showing all such required easements, in accordance with the approved plans. 12.

The permittee shall at all times fallow the approved Operation and Maintenance Agreement and provide the operation and maintenance necessary to assure that all components of the permitted stormwater system function at design condition_ The approved Operation and Maintenance Agreement outlines the necessary maintenance items and required maintenance intervals. The on -site runoff collection system of catch basins, piping, ditches and swales must also be maintained such that the one (1) inch runoff volume is adequately conveyed to the approved BMP(s). 14. Records of maintenance activities must be kept and made available upon request to authorized personnel of DENR. The records will indicate the date, activity, name of person performing the work and what actions were taken. 15. The permittee shall assure that permanent access to the permitted BMP components, including the collection system, is provided via recorded easements, common areas or public rights -of -way.

You clarified and answered all our questions and we were relieved to know that you are aware that we have worked very hard to be in compliance of the Storm Water Permit since we accepted it in May of 2014. In response to the inspection report: 1. As we discussed, we have been in continual contact with Larry Sneeden to complete his work on the pond modification and the required numbers for the surface area and storage volume. Our attorney just sent a letter to him on May 22, 2018 requesting he complete his work or refund our payment to him. This afternoon, we received an email from Larry stating he would not complete the work on the pond and will refund our payment. Therefore, we will now hire another engineer to do the work. Hopefully, one who will actually complete the job in a timely manner. 2. We did complete a sample of properties that we thought may be over their allowed BUA at the time we accepted the Storm Water Permit and filed it with the document. Going forward, we have met with all new homeowners and given them a copy of our ARC (Architectural Review Committee) procedures which clearly states the requirement of submitting an application for approval by the ARC for any changes to their property especially those changes that will add to the BUA and lists the maximum BUA for each section of the Wedgefield Subdivision. ALL applications must list the BUA of the property and detail the proposed project which is reviewed and verified by the ARC before being submitted to the Board for a vote. 3. During our Annual Meeting on February 10, 2018 we discussed scoping the pipes this summer to check for blockages and sediment build up. This plan was reported to all homeowners in the Minutes of the Annual Meeting that was sent to all. We expect to contract this work in July, 2018, weather permitting. We understand the importance of complying with the Storm Water Permit and will continue to strive to uphold all the requirements. Thank you for your follow up email clarifying the BUA overage issue. Sincerely yours, e� *Koreen LaRose President, WHOA cc: Brian Lambe Energy, Mineral & Land Resources ENVIRONMENTAL QUALITY June 4, 2018 Dr. Rose Newman & Mr. Melvin Nudelman 4920 Wedgefield Drive Wilmington, NC 28409 Subject: Drainage Complaint on Lot 220 Crosswinds South and Wedgefield at Crosswinds South Stormwater Management Permit No. SW8 921115 New 13anover County Dear Dr. Newman and Mr. Nudelman: ROY COOPER Governor MICHAEL S. REGAN Secretary WILLIAM E. (TOBY) VINSON, JR. Interim Director In late April, 2018, the Division received your complaint in which you expressed concerns about the flooding at the rear of your lot and about the built -upon area overages and how that might affect your resale value. Brian Lambe, an inspector with the Division of Energy, Mineral and Land Resources met with you on site to observe the conditions and to discuss your concerns. Neither the stormwater permit nor the stonmwater rules address flood prevention or poor drainage. The wetlands located behind your lot are the "low spot" in this area, and they receive runoff from a larger watershed that extends well beyond the property boundaries of Wedgefield and Crosswinds. The fact that the back of your lot is wet is not a violation of the permit. The Division met with representatives of the Wedgefield at Crosswinds South HOA on June 4, 2018 to discuss the items listed in the May 3, 2018 inspection report. The stormwater rules require that the swales, ditches, pipes and inlets within the project be maintained by the permit holder, at design condition. if anyone has altered, removed, redirected, resized or regraded any of the permitted components of the approved runoff collection system without the written permission of the Wedgefield at Crosswinds South FICA, Inc, then in order to maintain compliance with the permit, the FICA has to require that the person(s) who altered the system restore it to the permitted design condition. In regard to the allegation of overbuilding, unfortunately, that is true. The Division filed an injunction against the developer of Wedgefield and Crosswinds to force compliance with the permit. At the conclusion of the hearing, we all agreed to and signed a Consent Order on June 5, 2007, which prevents the Division from taking any action against the HOA for any existing non -compliances which were caused by the original construction. The HOA must ensure that those lots which are not overbuilt, remain so, and the HOA must ensure that any lot which is already overbuilt does not add more built -upon area. Your lot was built in 2006 prior to the signing of the consent order, therefore, your lot would be considered one of the existing non -compliances that the Division cannot act against. However, you and any future purchasers of your lot, are prohibited from adding more built -upon area. If you have any questions, please do not hesitate to call me at (910) 796-7215.

I wanted to pass on Cameron Weaver's direct number which is 796-7265. You can contact him to make arrangements to get copies of the approved plans made at yourexpense. Also; in regard to the BUA overage issue, I've gone over the Consent Judgment again and here are my thoughts on the BUA overage issue. I think that the intent of the order was to allow the existing overages to remain without being penalized. As of May 22, 2014, the HOA is responsible for any overages that result from any lot construction approvals given by the HOA. The HOA is not responsible for "cleaning up" the existing overages, but at the same time, the HOA should not approve any additional construction on those lots that are already over the maximum limit. It's my understanding from our meeting that is how you have been handling things. There's nothing wrong with questioning a plan and how the numbers were derived. In the end, it's your permit, and no homeowner should fault you for making sure that you stay in compliance. If you suspect that a lot owner is not being truthful with you regarding the extent of or amount of existing BUA, a no -cost option is to conduct an on -site inspection. I know you only have 30 days to approve or disapprove a proposed plan. Maybe this could all be avoided if you amended the declaration of covenants or the Architectural Guidelines to require that the plans submitted to the HOA for approval be prepared by a licensed surveyor (PLS) or professional engineer (PE) or landscape architect (LA). That takes the onus off of you and puts it back on the lot owner. The HOA does need to continue monitoring the lots to assure compliance. It may be helpful to the HOA to come up with a list of those lots that were already over their BUA limit at the time the permit was transferred. The HOA should continue to document and report any situations to their attorney, where a homeowner builds something on their lot despite being told by the HOA (in writing) that they cannot build more. I'll get a letter to the owners of Lot 220 (Rose Newman and Melvin Nudelman) regarding maintenance of the pipe and swale in the easement. From the standpoint of the State, you are responsible for maintaining the system of swales, ditches, pipes and inlets that collect the runoff and convey it to the pond. You are not responsible for eliminating swales and/or extending pipes within an easement (unless you voluntarily elect to do so). If a pipe, ditch, Swale or inlet has been altered by a property owner without your written permission, then you should notify the property owner to restore it to design condition at their expense.

College Road and Wedgefield Drive in New Hanover County to determine the status of compliance with the State Stormwater Management Permit Number SW8 921115 issued on May 22, 2014. The Division received a complaint of improper drainage on Lot 220 at 4920 Wedgefield Drive. DEMLR file review and site inspection revealed that the site is not in compliance with the terns and conditions of this permit. Please find a copy of the completed form entitled "Compliance Inspection Report" attached to this letter, which summarizes the findings of the recent inspection. As indicated in the attached inspection report, the following deficiencies must be resolved: l . As required per the Consent Judgment, and Schedule of Compliance Condition II.1 of the subject permit, once the permittee has removed accumulated sediment and stabilized the side slopes at 3:1 or flatter to provide as much surface area and volume as possible, the permittee is required to submit a permit modification and revised plans which reflect the permanent pool surface area and temporary design storage volume that have been provided. A modification was submitted in 2016, but the requested additional information has not been submitted. Please submit the information requested in that email dated September 16, 2016 from Linda Lewis (copy attached), by Jime 3, 2018. 2. Schedule of Compliance Conditions 11.3, 11.4 and 11.5 detail the requirements for handling overages of the built upon area which were permitted in the original and subsequent permit. As of the date the permit was issued, the Homeowners Association is charged with the following responsibilities: a) make on -going efforts as time and finances allow to identity and document any BUA overages on the lots; b) review all proposed lot construction, modifications and additions for compliance with the BUA limits; and c) monitor the project on a routine basis to ensure that all lots maintain compliance with the maximum BUA limits. Please provide copies of the lot review records conducted by the IIOA as of May 22, 2014. 3. Please maintain the pipe between Lots 219 and 220 by removing the accumulated sediment. The drainage in this area is intended to flow into the wetlands which then flows into the ditch that feeds the Crosswinds Pond. State of North Carolina I Enviror n ental Quality I Energy.

The back corner of their property is innundated with water. The property does back up to a wetland. I am unsure of the wetland delineation. The pipe extends test) 200' from the cul-de-sac inlet to a relatively flat area. Some sediment is in the bottom portion of the pipe that should be maintained (removed). The plan calls for a rip rap apron, not installed, but there is no evidence of erosive velocity. No flooding evident in the cul-de-sac. The complaint contends that adjacent property owner, lot 221, has excessive drainage into their yard. I explained that this is a civil matter, refer to Pendergrast v. Aiken. The complaint contends that the lots in the subdivision are overbuilt in excess of the deeded allowance of BUA. The BUA for former permit SW8 921115. Lots 1-37, is limited to 4500 sq ft. The BUA for former permit SW8 960317, Lots 201-239, is limited to 4300 sq ft. Please submit records of BUA additions, before and after May 22, 2014.

It appears that the temporary pool elevation is being lowered from the previously permitted 23.3 down to 22.2, which results in a drastically reduced storage volume that doesn't come close to meeting the minimum required volume. Is there some reason why the overflow elevation cannot be raised back up to 23.3 to provide additional storage volume and treatment? The curb inlet rim elevations in the street are at +26, so the water in the pond should not back up into the street. 2. The calculations appear to indicate that there is only 750 cubic feet of volume provided between elevation 21.45 (the proposed permanent pool elevation) and 22.2 (the proposed temporary pool elevation). This does not appear to be correct. The average surface area is 12900 sf which when multiplied by the difference in elevation of 0.75 feet, yields 9675 cf. Am I missing something? 3. Please add a detail of the revised outlet structure with the proposed elevation changes to the plans. 4. It looks like you are adding a new 24" galvanized overflow pipe with an invert of 24.2, is that correct? Is there some reason why 24.2 cannot be proposed as the temporary pool elevation? That's still 2 feet below the top of bank and 2 feet below the curb inlet rims. S. The side slopes of the pond on the northeast side appear to be flatter than 3:1. The consent judgment directed the HOA to regrade those slopes to 3:1 to gain as much surface area and volume as possible. 6. Are we keeping the pump system as the main means of drawing down the storage volume? Does the pump rate need to be adjusted based on these new elevations?

I emailed Larry and i, you again at the start of this year, requesting a status, but I still haven't received anything yet. If you will recall, the Consent Judgment allowed Wedgefield time to gather up sufficient funds to pay for the restoration work including regrading the pond slopes to get as much surface area as possible and removing sediment to gain as much design depth as possible. Schedule of Compliance Condition IL of the permit states the following: The permittee shall obtain an estimate of the depth of the accumulated sediment in the pond. If the sediment has accumulated to a point such that the pond depth is four feet or less, the permittee shall enter into an agreement with DEMLR regarding the time frame for removing the accumulated sediment such that the pond's design depth is restored to 5 feet. Along with or subsequent to the removal of the accumulated sediment, the permittee shall enter into an agreement with the Division to stabilize the side slopes of the Front Pond as per the Consent Judgment, and to provide as much permanent pool surface area as reasonably possible, given the physical constraints. The permittee shall then submit a permit modification and revised plans to the Division reflecting the permanent pool surface area and temporary pool storage volume that have been provided. At the end of the restoration effort, Wedgefield is supposed to submit their findings of how much surface area, and volume has been provided so that those numbers can be placed into the permit as the benchmarks for future compliance. The Consent Judgment was entered on June 5, 2007, nearly 9 years ago. It's time to fully comply with that Consent Judgment by documenting the as -built pond information in the permit. Please provide the required information by June as -built survey of the surface area at permanent temporary pool volume calculations. If you have me know. Thanks. Linda Lewis, E.I.

This is the first I am hearing of this. Do you know anything about his complaint? The only "plug" I am aware of is the one further down the ditch between Wedgefield and Crosswinds. Did the HOA install this "plug" after our negotiations? If the HOA did not install the plug, then do you know who did? Of course with all the rain we've had, flooding complaints are definitely on the rise. Please remind the lot owners in Wedgefield that the Division has no jurisdiction over flooding. I would have thought that became clear during the hearing a few years ago, but memories can be short. Btw- Larry Sneeden came by our office last week and I was able to give him a note that you wished to speak with him. Apparently, he lost all his email due to some computer glitches or hacks.

(hereinafter "Wedgefield"), and Defendant Crosswinds HOA, Inc. (hereinafter "Crosswinds"), and William K. Trask (hereinafter "Trask"), hereby agree to the entry of this Consent Judgment in order to resolve the matters in controversy between the parties. Service of process of the Complaint and the Amended Complaint filed herein is hereby accepted and the jurisdiction of this Court hereby acknowledged by all Defendants. The parties agree that this Consent Judgment may be signed out of county, out of term or session, and out of district. The State brought this civil action to compel B&D to take corrective action to restore stormwater control measures as required by Stormwater Management Certification No.921115 and Stormwater Management Certification No. 930710 ("the Certifications"). The stormwater control measures, which are required by the Certifications are located in the NZAP Crosswinds and Wedgefield residential subdivisions in Wilmington, New Hanover County. The State filed an Amended Complaint on or about March 14, 2006, to add Crosswinds and Wedgefield as defendants in accordance with an order entered by The Honorable D. Jack Hooks, Jr. on or about February 8, 2006, ruling that Crosswinds and Wedgefield are necessary parties to any final decision in this litigation. UZEL TIONS QF FACT Plaintiff is the sovereign State of North Carolina. This action was brought on the relation of William G. Ross, Jr., Secretary of the Department of Environment and Natural Resources, the State agency established pursuant to N.C. Gen. Stat. § 143B-275, gt sec.., and vested with the statutory authority to enforce the State's environmental laws, including laws enacted to protect the water quality of the State. 2. Defendant B&D Development Corporation is a North Carolina corporation doing business in New Hanover County, North Carolina. B&D's registered agent is Dick J. Thompson. B&D's principal mailing address and registered office address is 111 Merchant Lane, Carolina Beach, North Carolina 28248. 3. Defendant Wedgefield is an association of property owners served by the stormwater control systems which are the subject matter of this civil action. 4. Defendant Crosswinds is an association of property owners served by the stormwater control systems which are the subject matter of this civil action. 5. On or about April 28, 1993, B&D submitted a revised application for a Certification of Compliance with Stormwater Regulations for Stormwater Project 2 li No. 921115, Wedgefield, to DENR's Division of Water Quality Wilmington Regional Office ("DWQ"). 6. On or about July 19, 1993, B&D submitted an application for a Certification of Compliance with Stormwater Regulations for Stormwater Project No. 930710, Crosswinds, to DWQ. 7. On or about October 12, 2000, R&D responded to DWQ and offered to take collective action on the rear pond, including provision of additional surface areas and volume based upon the design criteria then in effect to the extent reasonably possible. g. On February 26, 2001, DWQ issued a Final Notice of Violation to B&D which set forth violations of the Certification committed by B&D. The final Notice of Violation was received by B&D on February 27, 2001. 9. On April 20, 2001, B&D submitted an application for modification, which proposed corrective action to bring the rear pond into compliance with the Certification. 10. On June 25, 2001, DWQ requested additional information about the rear pond from B&D. 11. On December 3, 2001, DWQ informed B&D that its modification application remained incomplete and that the Company's proposed time frame for the completion of the modifications was unacceptable. 12. On December 27, 2001, B&D stated in a letter to DWQ that meeting a deadline of January 3, 2002, for completion of any work which DWQ and R&D might agree upon was not possible for B&D to achieve. 3 13. On November 6, 2002, DWQ issued a Notice of Violation to B&D for violations of Stormwater Permit No. 921115 (the front pond), which was received by B&D. 14. The State did not issue any Notices of Violation to Wedgefield or Crosswinds. 15. Wedgefield has limited financial means and needs a reasonable period of time to maintain and make repairs to the Wedgefield pond. 16. Because of the front berm it is impracticable to restore the slope on the west bank of the Wedgefield pond to a 3:1 ratio. Similarly there is limited space to access the north bank of the pond due to swimming pool construction at that site. 17. There is limited access to the front pond because of the front berm between College Road and the front pond and there are no other access easements to the front pond. CONCLUSIONS OF LAW This Court has personal jurisdiction over the parties and subject matter jurisdiction over the controversy. The Complaint states a claim upon which relief can be granted. 2. This Consent Judgment entered into by the parties is fair and will terminate the controversy between them in regards to this proceeding. ORDER IT IS THEREFORE, upon consent of the parties, and without the taking of any testimony, ORDERED, ADJUDGED and DECREED: Defendant B&D shall: (a) Within ninety (90) days from the entry of this Consent Judgment perform such excavation as is necessary to provide additional surface area at the rd permanent pool elevation in the rear pond as permitted under 930710, on the rear portions of Lots 304 and 305, Section 5, Crosswinds, as shown on a map recorded in Map Book 35, Page 316, New Hanover County Register of Deeds, owned by Trask as shown and highlighted on the attached Exhibit A, to meet the requirements of 15A NCAC 2H.1003(i) (1988), to the extent feasible. Crosswinds and Trask shall provide B&D access to the pond to perform the work and release B&D from any claims of Crosswinds or Trask associated with the work. At the conclusion of the work, Trask and spouse shall deed to Crosswinds those portions of Lots 304 and 305 of Crosswinds as shown and highlighted on the attached Exhibit A. The outlet structure shall remain "as is" with no increase in elevation. (b) Within thirty (30) days from the entry of this Consent Judgment, B&D shall pay to Crosswinds the sum of $6,500.00 to increase the number or size of the pipe(s) connecting the two rear ponds. 2. Wedgefield and Crosswinds shall evaluate the capacity of the ditch which connects the front and rear pond to convey the surface runoff, as close to the original plan as practicable to their respective wet detention ponds. Subject to the results of that evaluation, Wedgefield and Crosswinds may install a plug in the interior drainage ditch at the appropriate break point, contingent on the removal, by any third party, of any hydraulic barriers downstream, in the Highway 132 ditch. Neither Wedgefield nor Crosswinds shall be required by this Consent 5 Judgment to remove any such hydraulic barriers downstream of the subdivisions. Crosswinds shall be required to maintain the above -described ditch, piping and other appurtenances and keep them clear of obstructions. 3. (a) Wedgefield shall remove silt from the front pond to restore its depth, as near to the original plan as practicable. Wedgefield shall perform the work on the front pond with a backhoe and shall only be required to remove the sediment from the interior of the pond to restore the slopes on the south bank and north bank to as close as a 3:1 ratio as practicable. Wedgefield shall not be required to restore the slope on the west bank of the front pond to a 3:1 ratio. Wedgefield may utilize the spoil material from the excavation to restore the south and north banks' slopes. Any action by Wedgefield is contingent upon the North Carolina Department of Transportation: granting a permanent access and maintenance easement to the front pond. Any action by Wedgefield is further contingent upon Wedgefield being able to construct permanent access from Highway 132 to the front pond for no more than $2,500.00. DWQ and Wedgefield shall negotiate an appropriate schedule for completion of the work. (b) Within thirty (30) days from the entry of this Consent Judgment, B&D shall pay to Wedgefield the sum of $6,500.00 to help defray the costs for the activities referenced in paragraph 3(a) herein. 4. Upon completion of the pond excavation, Wedgefield shall clear, reseed and establish a permanent groundcover on the banks surrounding the front pond permitted under 921115 from the water line to the top of the slope of said banks. 0 M 5. The Plaintiff shall, to the extent required by the North Carolina General Statutes and any rules promulgated there under authorize, grant and provide any and all permits, if necessary, required for B&D and/or Wedgefield, and /or Crosswinds, at no cost to perform the activities which are referenced herein and agreed upon by the parties. All activities undertaken pursuant to this Consent Judgment are deemed by agreement of the parties to be maintenance which will not require the application for, or issuance of, any permits by the plaintiff. 6. The Court shall retain necessary jurisdiction of this matter for purposes of enforcing the terms of this Consent Judgment and, for determining upon any motion by either party that the requirements of this Consent Judgment have been met and that dissolution of it is appropriate. 7.

You can call Cameron Weaver at 910-796-7303 and make an appointment to meet him over at Allways Graphics on Racine Drive where they can scan, email and/or printout a copy of the plans at your expense. Please let Cameron know the permit number is 921115 when you call. Because all the runoff is mostly piped already and treated in the pond, extending the pipe a little further is not a problem and will not be a permit violation.

I've looked all over, and we can't find any plans within our board. Can you please send me the "Outlet protection see detail on sheet 2 of 5" detail? If I need to get it some other way, if you can tell me how that is, I would appreciate it. I'm trying to work with the realtors on this. In addition, they are asking for some kind of letter from the HOA giving permission to the new lot owner to extend this pipe all the way to the back of the yard and discharge on the back side of the fence, at their expense. I believe you said the other day that that would be acceptable, but just wanted to make sure before I did anything like that. Please let me know. Thanks Linda!

It's 150 feet long, and ends at an invert of 19.9. I've attached a scan of that area from the approved plan for your use. The HOA should have a copy of the approved plans.

If the sediment has accumulated to a point such that the pond depth is four feet or less, the permittee shall enter into an agreement with DEMLR regarding the time frame for removing the accumulated sediment such that the pond's design depth is restored to 5 feet. Along with or subsequent to the removal of the accumulated sediment, the permittee shall enter into an agreement with the Division to stabilize the side slopes of the Front Pond as per the Consent Judgment, and to provide as much permanent pool surface area as reasonably possible, given the physical constraints. The permittee shall then submit a permit modification and revised plans to the Division reflecting the permanent pool surface area and temporary pool storage volume that have been provided. I envisioned that the bid proposal would just be a part of the overall permit -required "agreement" between the Division and the HOA for restoring the pond. You should incorporate the RPS bid into your submission to the Division and add in the goals to be achieved and the timeframes to achieve them. A few things to notice: 1. The pond design depth needs to be restored to 5 feet. There is no mention of what the goals of removing the sediment are, which is to restore pond depth and to create surface area. Item #1 of the RPS estimate only discusses removing 500 cy of material to add pond volume. 2. The permit requirement is to provide as much permanent pool surface area as reasonably possible. The RPS estimate makes no mention of if or how much additional surface area will be provided as a result of the sediment removal. #4 of the RPS estimate needs to specify that the repaired side slopes should be restored to a 3H:1V slope. This is another way of achieving additional surface area - by restoring the angle of those slopes that have sloughed down back to the required 3HAV. Instead of leaving those "point sources" to undo all the good that will be done, I suggest extending the downspouts to the water's edge to avoid the slopes and the potential erosion. This could be a part of the RPS bid work, or it could be a bullet -point in the agreement that the HOA will notify those lot owners to take care of it themselves. 5. In order to provide the necessary revised plans reflecting the added surface area , you may want to include an as -built survey as part of the RPS bid work, unless you will be making arrangements directly with a surveyor to get that done. Hope these comments help.

Hope you're doing well! I think we are FINALLY ready to get moving on getting this pond where it needs to be. Please see attached quote from Retention Pond Services. Please read over it to make sure that it fits all DENR's needs, and give your blessing on it. Once we get that, we will schedule RTS to come and do the work. In addition, I have forwarded a copy of the signed permit over to Abby at RTS just for her to read one more time to make sure there's nothing they are missing as well. By the way, the new board is no longer using Brian Geschikter as our lawyer, so please don't send anything through him so that we don't have to pay additional fees. Thanks!

Specializing In all phaaea of Aquatic and Wetland Maintenance NAME/ADDRESS BID DATE BID# Wedgefield HOA 5/12/2014 2718 4721 Wedgefield Drive Wilmington, NC 28409 TERMS PROJECT NAME Due On Completion DESCRIPTION TOTAL Retention Pond Services, Inc. ("RPS") proposes to complete the following scope of work: 28,300.00 1. Remove approximately 500 cubic yards of accumulated sediment to add pond volume. All removed sediment will be disposed offsite. 2. Cut 13 pine trees from the south pond slope. The trees will be cut flush with the ground and disposed of offsite. 3. The collars of the two intakes will be brought to the appropriate grade and stabilized using class B rip rap placed over filter fabric. In addition class B rip rap will be placed over filter fabric to create an energy dissipation pad at the toe of each of the two intakes. Approximately 30 tons of class B rip rap and 5 tons of compactible fill will be used in performing the work described in this numbered paragraph. 4. Repair the areas of erosion on the west slope using approximately 15 tons of compactible fill. Repair the areas of erosion and rodent holes on the north slope and south slopes using approximately 30 tons of compactible fill. Stabilize all slope banks using a hydroseed mixture with the appropriate amendments. The silt fences on the north slope will be removed and disposed offsite. 5. There are several gutter downspouts terminating on the north slope. Any discovered downspout will be capped. 6. Repair the tracking along the access area using centipede sod. This area will be raked out and the sod will be tapered in to the height of the adjoining grass. —There are areas of erosion on the north slope directly attributed to point source discharge along wood fencing that borders property lines. This scope of work does not contemplate altering the property of any homeowner and thus the point sources will continue to result in areas of erosion unless the areas are addressed by the owner of the property who has a point source discharge along their fence. "'Wedgefield HOA will obtain permission from the owner of improved Lot #37 to access the pond along the berm parallel to College Road. by: Date I Thank you for the opportunity to quote this work.
