Yes, that is correct, the total on -site streets is 440,384 rather than 440,684. Thanks, M From: Johnson, Kelly [mailto:kelly.p.iohnson@ncdenr.eov] Sent: Friday, October 24, 201412:41 PM To: Monica Valsi Subject: RE: SW8 030917, Village at Mott's Landing Monica, So, if I understand this correctly I should correct the table on the application to show that the total onsite streets is 440,384 rather than 440,684. 1 have been back -calculating the CO Swale data from the total, so if the total streets is 300 less that should fix things. I am pretty sure that that is the plan, but let's follow up next week just to be sure and then we will get it out of here. Thanks, KJ From: Monica Valsi [mailto:monica-trippenci(@ec.rr.com] Sent: Thursday, October 23, 2014 11:42 AM To: Johnson, Kelly Subject: RE: SW8 030917, Village at Mott's Landing Kelly, Email is back up (for now). I'll be in the office until noon tomorrow, so if you get in before then please call. Otherwise, regarding your RFAI #1.a., the onsite streets impervious area for the CO Swale should be 119,181 not 119,481. Therefore; the total reported impervious area of 1,821,178 sf is correct. I've attached our impervious calculation table for simplicity.

Churchill Dr. Wilmington, NC 28403 Subject: Request for Additional Information Stormwater Project No. SW8 030917 The Village at Motts Landing New Hanover County Dear Dr. Sobol: John E. Skvada, III Secretary The Wilmington Regional Office received and accepted a modified State Stormwater Management Permit Application and Renewal for The Village at Motts Landing on September 19, 2014. A request for additional information was mailed on October 9, 2014 and a response was received on October 20, 2014. A preliminary in-depth review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Application: a. Impervious Total in Table: Please check the total impervious on the application as summarized below. The total, DA1, DA2, and DA3 impervious area values are provided in the application and the CO Swale data is determined from the difference of the Total and the three drainage areas. The data appears to be off by 300sf. For instance, 1, 147,500+440,684+59,740+31,395+156,251 = 1,835,570sf rather than 1,835,270sf. I have updated the impervious area summary document to reflect the changes from your recent letter. It is attached.

Application: a. Impervious Total in Table: The total impervious area of 1,821,178 sf C � on the application is correct. The impervious area of the Onsite Streets for the Curb Outlet indicated on your table should be 119,181 1' in lieu of 119,481. b. 30% Overall: Permit Correction: Acknowledged. ii. Option: We have revised the permit application to "max out" the curb outlet swale's future impervious so that the project is 30% overall. A revised page 3 of 6 of the Stormwater Permit Application, a revised page 2 of 5 of the Low Density Supplement and revised swale calculations are provided. --2' Calculations: Apologies for the omission. ter. Curb Outlet: Revised swale calculations are provided. --b. Pond 3: i Revised calculations for Pond 3 are provided. `ri. A revised page 1 of 4 of the (existing, older version) Wet Detention Basin Suppiement is provided. 3. Doc entation: tea. copy of Exhibit B (Total Impervious Area per Lot) which was . . w previously recorded in the deed restrictions is provided. As all of the ? lots were not included in Exhibit B, new deed restrictions with an updated Exhibit are in the process of being recorded. Attached are �° L�> the deed restrictions with the updated exhibit (Exhibit A) indicating the allowable Total Impervious Area per Lot that will be recorded. `--KPE Certifications provided. %- l Drainage Area Map: An additional copy is provided. Please note that we have revised some of the lots allowable impervious surface square footages. This revision is mainly due to the allowable square footage per lot that has already been recorded. This revision has changed the onsite building/lots impervious area for Pond 2, Pond 3, and the curb outlet as previously submitted; however, the total impervious area for the aforementioned drainage areas remain the same as we subtracted/added the difference from the future impervious allocation. For simplicity we have indicated the previously referenced revisions in green on your Table 1 — DRAFT — Permit Attachment under DATE 2014 Modification — As Submitted column. Please review for approval and contact us with any questions, comments or if you need additional information. Thank you. Sincerely, Tripp Engineering, P.C. 'OV % C-& VAJU- Monica L. Valsi, E.I.

Churchill Dr. Wilmington, NC 28403 Subject: Request for Additional Information Stormwater Project No. SW8 030917 The Village at Motts Landing New Hanover County Dear Dr. Sobol: John E. Skvada, III Secretary The Wilmington Regional Office received and accepted a modified State Stonnwater Management Permit Application and Renewal for The Village at Motts Landing on September 19, 2014. A preliminary in-depth review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Application: a. Impervious Total in Table: Please check the total imperious on the application. It appears to sum to 1,821,478sf rather than 1,821,178sf. Please make any necessary corrections (see the attached table). b. 30% Overall: i. Permit Correction: The 2011 permit inadvertently left out the overall 30% low density requirement that was in the 2008 and 2010 permits. This requirement will be added back into your permit. ii. Option: Please see the attached table. The project is currently submitted 29.77% impervious. You have the option to "max our the curb outlet swale's future imperious area such that the project is 30% overall (assuming that the swales can handle the additional area draining to them). This would increase your available impervious area by 13,792 square feet. If you choose to "max our the data please make the necessary changes to the curb outlet calculations, low density supplement, etc. 2. Calculations: It appears that the calculations were omitted from the package. Please submit: a. Curb Outlet: Calculations that the swales can accommodate the increased imperious area. b. Pond 3: i. Please submit calculations that the increase of 30,000sf of imperious area can be treated by the existing pond. ii. Please submit the revised pond supplement showing the revised impervious data. (You can submit an updated version of the existing supplement which is an older version if that is easier.) 3. Documentation: Please submit the following paperwork which is not currently on file. a. Recorded deed restrictions reflecting the imperious area allocation in Table 1 b. PE Certification(s) (if the ponds have been built) 4. Drainage Area Map: Please submit an additional copy of the drainage area map. Please remember that a change to one number may have a domino effect on other numbers. Please check all plans, calculations and forms to ensure that the numbers are consistent throughout. Please note that this request for additional information is in response to a preliminary review. The requested information should be received in this Office prior to November 10, 2014, or the application will be returned as incomplete. The return of a project will necessitate resubmission of all required items, including the application fee. Division of Energy, Mineral, and Land Resources Land Quality Section — Wilmington Regional Office 127 Cardinal Drive Extension, Wilmington, North Carolina 28405 - (910) 796-7215 / Fax: (910) 350-2004 SW8 030917 October 9, 2014 If you need additional time to submit the information, please mail, email 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 of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A. Please reference the State assigned project number on all correspondence. Any original documents that need to be revised have been sent to the engineer or agent. All original documents must be returned or new originals must be provided. Copies are not acceptable.

The subdivision was designed in three separate drainage basins and curb outlet drainage areas. Each basin was designed as high density and treated by wet detention. Each pond was designed to meet the State's 1" and the County's 25-year pre -post requirement. Each curb outlet drainage area was designed as low density and treated by curb inlets and grassed swales. Outflow from all ponds and curb outlets drain to Mott's Creek, classification C-SW. Modifications to this previously permitted plan have been made. Some lots have been relocate / renumbered throughout P, tease 1. Concrete sidewalk is proposed on one side of each roadway. Swale #5 has also been relocated. Below is a description of the revised impervious areas for each drainage basin and curb outlet drainage area. Drainage Basin #1 has an area of 43.44 acres as previously permitted. Within this basin is 96 lots totaling 396,000 sf, 157,989 sf of asphalt streets including curb and gutter, a 31,395 sf amenities area, 17,815 sf of concrete sidewalk, and 90,389 sf for future development for a total impervious surface area of 693,588 sf. The total impervious surface area is the same as previously permitted. This area will be treated by wet detention pond #1. Drainage Basin #2 has an area of i 7.70 acres as previously permitted. Within this basin is 57 lots totaling 275,500 sf, 101,298 sf of asphalt streets including curb and gutter, 21,745 sf of concrete sidewalk, and 21,268 sf for future development for a total impervious surface area of 419,811 sf. The total imperious surface area is the same as previously permitted. This area will be treated by wet detention pond #2. Drainage Basin #3 has an area of 19.50 acres as previously permitted. Within this basin is 30 lots totaling 141,500 sf, 61,916 sf of asphalt streets including curb and gutter, 8,290 sf of concrete sidewalk, and 21,210 sf for future development for a total impervious surface area of 232,916 sf. The total imperious surface area is 30,000 sf more than what was previously permitted. This area will be treated by wet detention pond #3. The additional 30,000 sf of impervious surface meets the State's 1.5" storm in lieu of the 1" design storm without pond modification. Revised calculations are provided that demonstrates the aforementioned design as well as the County's 25-year pre -post requirement. The curb outlet drainage areas consist of 72 lots totaling 324,000 sf, 119,181 sf of asphalt streets including curb and gutter, 11,890 sf of concrete sidewalk, and 19,792 sf for future development for a total impervious surface area of 474,863 sf. The total impervious surface area is the same as�previousl . . ed. These areas will be treated with curb inlets and grassed swales.

Churchill Dr. Wilmington, NC 28403 Subject: APPLICATION RETURN SW8 030917: The Village at Mott's Landing New Hanover County Dear Mr. Sobol: John E. Skvarla, III Secretary On June 27, 2014, the Division received an incomplete State Stormwater Management Plan Revision Application for the project listed above. The plan revision application is being retumed because the application package lacked the necessary elements to accept it for review. This application is to add curb outlet swales to the project, which is a modification rather than a plan revision. Additionally, it appears that lot numbers have been re -numbered, and it appears that the drainage area(s) may have changed for other stormwater treatment devices. If necessary, please update Table 1 from the November 30, 2011 permit with your modification package. Please visit DWQ's website at http://h2o.enr.state.nc.us/su/bmp forms.htm to download the latest available forms. Please provide the requested information and return the package to the address below. Note that the 90-day statutory permit review time begins upon receipt of a complete application. If you have any questions, please do not hesitate to call me at (910) 796-7331 or email me at kelly.p.johnson@ncdenr.gov.

Not sure what's going on, but... We are in receipt of your September 5, 2013 correspondence - Second Request for a Stormwater Management Permit Application for The Village at Motts Landing. We have not yet submitted the stormwater permit application for the road extension of Jacob Mott Drive because the owner has decided to go ahead and permit all of Phase 2 at one time, instead of breaking it up. A permit application package for Phase 2 will be submitted in the near future. As for Phase 1 B, all impervious areas in phase 1 B were accounted for in the permit modification issued on November 30, 2011. At that time, we included all of Phase 1 A and Phase 1 B in the modification to eliminate the necessity of going back for an additional modification later on. I hope this clears up the issues at hand. Please let us know if you need any additional information. Thank you. Della Baird Tripp Engineering, P.C.

North Carolina Department of Environment and Natural Resources Division of Energy, Mineral, and Land Resources Tracy E. Davis, PE, CPM Director September 5, 2013 Dr. Arnold Sobol, Member- Manager Aftew Properties, LLC 2020 S. Churchill Dr. Wilmington, NC 28403 Pat McCrory, Governor John E. Skvarla, III, Secretary Subject: Second Request for a State Stormwater Management Permit Application The Village at Motts Landing Stormwater Project No. SW8 030917 New Hanover County Dear Dr. Sobol: On July 2, 2013, the Wilmington Regional Office requested that you submit a revised plan for The Village at Motts Landing for the extension of Jacob Mott Drive to Carolina Beach Road. The Division has received further notification from New Hanover County that you are proposing to develop Phase IB of this project. To date, the Division has not received your request for a plan revision for either of these changes to the existing approved plans. The North Carolina Administrative Code requires any project that is part of a larger common plan of development, or that proposes more than 10,000 square feet of new built -upon area, or that must receive Sedimentation and Erosion Control Plan approval, or that must receive a CAMA Major permit, to apply for and receive a Stormwater Management Permit. Any construction on the subject site, .prior to receipt of the required permit, will constitute a violation of 15A NCAC 2H.1000 and may result in appropriate enforcement action by this Office. If the Either a Stormwater Permit Application Package including 2 sets of revised plans, completed application form, fee, and supporting documentation, or a written response regarding the status of this project and the expected submittal date must be received in this Office no later than October 5, 2013. Failure to respond to this request may result in the initiation of enforcement action, and construction may experience a subsequent delay.

Reeder John E. Skvarla, III Governor Acting Director Secretary July 2, 2013 Dr. Amold Sobol, Member Manager Aftew Properties, LLC 2020 S. Churchill Dr. Wilmington, NC 28403 Subject: Request for State Stormwater Management Permit Application The Village at Motts Landing Stormwater Project No. SW8 030917 New Hanover County Dear Dr. Sobol: On July 1, 2013, the Wilmington Regional Office received notification from New Hanover County that you are proposing to expand this project. Please be advised that it appears that Jacob Mott Drive will extend from the currently permitted area covered by SW8 030917 to Carolina Beach Road. Please be advised that this will have to be permitted either by a modification to SW8 030917 or under a new permit. The North Carolina Administrative Code requires any project that is part of a larger common plan of development, or that proposes more than 10,000 square feet of new built -upon area, or that must receive Sedimentation and Erosion Control Plan approval, or that must receive a CAMA Major permit, to apply for and receive a Stormwater Management Permit from the Division of Water Quality. Any construction on the subject site, prior to receipt of the required permit, will constitute a violation of 15A NCAC 2H.1000 and may result in appropriate enforcement action by this Office. If the area in question is already covered by a State Stormwater permit Dlease notifv us of that in Your response. Either a Stormwater Permit Application Package including 2 sets of plans, completed application form, fee, and supporting documentation, or a written response regarding the status of this project and the expected submittal date must be received in this Office no later than August 5, 2013. Failure to respond to this request may result in the initiation of enforcement action, and construction may experience a subsequent delay. The NPDES 010000 Federal Stormwater Permit that accompanies the Erosion Control Plan approval letter must NOT be considered the Coastal Stormwater Management Permit, which will be signed by the Supervisor of the Surface Water Protection Section. Please reference the Project Number above on all correspondence. If you have any questions, please call me at (910)-796-7215.
