I like the Draft that you wrote. However, the BLIA per lot summary is incorrect. Lot #214 is now a residential lot w/ 4,000 sf of BLIA. There is no Lot 227, Lot #72 is 5,000 sf, not 4,500 sf Lot #130 is 4,500 sf, not 4,000 sf Lot # 136 is 4,500 sf, not 5,000 sf The total Lot BUA is 1,041,000 sf (see my attached spreadsheet) The BUA Plan Revision Summary needs to be corrected as well. I don't want the total Impervious value of 1,748,918 sf to change, so there will be no correction. The Lots, ft2 Total Correction should be 1,041,000 sf The Pond 2 Lots value should be 276,000 sf The Curb Outlet for Lots should be 309,000 sf Change the FUTURE for Pond #2 to be 47,224 sf and the Total Future to be 305,759 sf. (I don't want to lose the extra 9,000 sf for Pond #2). If you want me to, I will edit these spreadsheets for you if you send them to me (if you are confused by all of what I just wrote - lol). What do you need from me now to move this along so that you can issue the revised SW permit? If the client wants to add lots later, we will file a MOD. But for now, let's get this revision settled.

It appears that the original SW application that was submitted and approved had a mistake in the calculations of the BUA for the lots. The actual total BUA for the lots is 1,040,500 sf, not 1,050,000 sf. I arrived at the 1,040,500 sf number by using your Lot BUA spreadsheet and filled in the assigned BUA for each of the 226 lots. What you have shown in the spreadsheet for August 22, 2008, totaled 1,045,000 sf. This is also incorrect because you included Lot #214 which was not a residential lot (if it was to be included, the total number of lots would then be 227 and not 226). If you subtract out the 4,500 sf for Lot #214 from your total, the amount is 1,040,500 sf. I have a follow up question for you. What needs to be done now so that the SW Permit shows the 1,040,500 sf for all of the lots? OR In the latest design and lot layout assigned to Pond #2, the Lot BUA is 9,000 sf less than what was approved (276,000 sf vs. 285,000 sf). Can I increase the number of total lots draining to Pond #2 so that I arrive at the 1,050,000 sf Lot BUA? If so then the total number of lots would be 228. Is this a problem for NCDENR-DWQ?

Kelly To: Larry Knoerl Sent: Tuesday, May 18, 2010 7:22 AM Subject: RE: SW8 030917 - Village At Motts Landing OK, thanks.... As for the pond, a pond can always be "bigger" than it is required to be. So, if the pond was originally designed to hold 100,000sf of BUA, but the impervious has been reduced such that the pond only needs to hold 90,000sf then it is OK to still build the pond to hold 100,000sf as it was permitted. In fact, if you have "extra" BUA that the pond can hold, you may want to claim that "extra" as "future" in case they want to add things later. For instance, if they want to add a turn lane or put in a sidewalk in a few years then the permit will still show the pond to be able to hold the 100,000sf and the permittee will just have to submit for a plan revision to reallocate the "future" 10,000sf to "sidewalk" or "road". Plan revisions in the regular program are free. If you don't claim the "extra" as "future" then you may run into problems later if you want to add something because if you have to rewrite the permit text (other than just reallocating BUA between BUA types), then you have to get a mod ($505). Having extra or "future" is always a good thing to have because you never know what will come up. KJ From: Larry Knoerl [mailto:Larry-trippeng@ec.rr.com] Sent: Monday, May 17, 2010 11:26 AM To: Johnson, Kelly Subject: SW8 030917 - Village At Motts Landing Kelly: I am working on responding to your comments dated May 10, 2010 and I have some questions for you. But first, a few comments. The original permit was for 226 lots. This has not changed - there still are 226 lots. When the original permit was issued, the lots numbered from 1-227, but lot #214 was not a residential lot and therefore was not counted. Lot #214 was to be used for parking for the Amenities Area. Don't ask me why the original engineer did it this way, but that is what he did. Now we moved the Amenities Area to a different location which changed some of the lots around. Lot # 214 was no longer needed for parking so it became a residential lot. The surveyor, unbeknown to this office, redesigned the lots and road around the island on the north side of the project. Doing so, he lost a lot compared to the original design. The gaining of Lot #214 was offset by losing the lot in the island. The result is that we renumbered the lots from 1-226, there is no longer a Lot #227. Please check your plans again to see if Lot #91 is shown on the August 22, 2008 plans. It is shown on the plans we have (southwest of Lot #90). Lot #91 was accounted for in the assignment of BUA for this project (4,500 sf). The original SW Permit DID include lots 59-64 and should have been included on the August 22, 2008 plans. I believe that I did show Lots # 59-64 on the latest plans as being part of Phase 1, although it will be built at a later time.. I put a Phase Line in the plans showing where Phase 1 ends and Phase 2 starts. As per your request, I will add a Project Area Boundary to the plans. Now for my question. Can a pond be allocated more BUA than will actually be used? I am asking this because of Pond #2. It was permitted with 285K sf and now requires less. Please let me know.

Sullins Dee Freeman Governor Director Secretary May 10, 2010 Dr. Arnold Sobol, Member Manager Aftew Properties, LLC 2020 S. Churchill Drive Wilmington, NC 28403 Subject: Request for Additional Information Stormwater Project No. SW8 030917 The Village at Motts Landing New Hanover County Dear Dr. Sobol: The Wilmington Regional Office received and accepted a Plan Revision request for a State Stormwater Management Permit for The Village at Motts Landing on March 5, 2010 and a response to my April 19, 2010 additional information request on May 6, 2010. 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: 1.) Impervious allocation: I have enclosed the summary table that was previously sent with my April 19, 2010 letter which specifies the amount of built upon area (BUA) per lot previously permitted to drain to each pond and contrasts this information with the currently -proposed BUA configuration. Your May 6, 2010 letter indicates that the table is correct. a. The August 22, 2008 permit states, "The project is permitted for 226 lots. Lots 1-46 and 136-154 are limited to a maximum of 5,000 square feet of built -upon area, as defined by the stormwater rules, and as indicated in the approved plans. Lots 130-132, 213, 215-227 and 155 are limited to a maximum of 4,000 square feet of built -upon area, as defined by the stormwater rules, and as indicated in the approved plans. All other lots are limited to a maximum of 4,500 square feet of built -upon area..."

There appear to be some inconsistencies between what has been permitted and what is proposed. 226 lots were previously permitted. Some of the inconsistencies I have found include the following. There may be others that I have not identified. Please make any necessary corrections: i. It is my understanding from March 2010 emails with your engineer that the number of lots is intended to be maintained. If the number of lots is changing, then this should be a permit modification rather than a plan revision. 1. The enclosed table shows that Lot 227 was previously allocated for 4,000sf. But, there is not a Lot 227 on the plans received on May 6, 2010. 2. There does not appear to be a Lot 91 on the August 22, 2008 approved plans but Lot 91 appears on the May 6, 2010 plans. ii. The permitted plans exclude the area covered by Lots 59-64, but the impervious area for these lots (4,500sf per lot) appears to have been included in the overall BUA accounting in the August 22, 2008 permit. The May 6, 2010 plans state that, "Phase 1A [Lots 59-64] is part of Phase 1, but to be constructed at a later time than remainder of Phase 1." Please clearly label the project area for this permit on the plans. c. The total BUA for Pond 2 on the table submitted on May 6, 2010 is shown to be both 276,000sf and 285,000sf. Please make any necessary corrections. d. Please show the drainage area line for each BMP on the plans. 2.) Deed Restrictions: a. Lot Summary: Please submit the information required by the enclosed table which summarizes which lots drain to each drainage area, the BUA per lot, the total BUA in each drainage area for all of the lots in the drainage area, and that the total BUA in each drainage area for all of the lots equals the total permitted BUA for each drainage area. If the lot numbers in the enclosed table need to be revised, please do so. b. Deed Restrictions: Please submit a copy of the recorded deed restrictions containing all of the required statements as listed in the current permit. If lot number have been revised such that the deed restrictions need to be revised please do so and submit the most current recorded deed restrictions. 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 May 19, 2010, 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, email or fax your request for a time extension to the Division at the address and fax number at the bottom Page 2 of 3 SW8 071216 -May 10, 2010 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.

Churchill Drive Wilmington, NC 28403 Subject: Request for Additional Information Stormwater Project No. SW8 030917 The Village at Motts Landing New Hanover County Dear Dr. Sobol: The Wilmington Regional Office received and accepted a Plan Revision request for a State Stormwater Management Permit for The Village at Motts Landing on March 5, 2010. 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: 1.) Impervious allocation: Please verify that the enclosed BUA Summary table reflects the impervious area configuration requested for this project. 2.) Lot Configuration: It appears that lot 136 has been added north of lot 120 on the plans submitted for this plan revision. However, the approved plans show that lot 136 is west of lots 137 and 154. Please submit revised plans showing all of the lots for the entire project in their revised configuration from the plans permitted on August 22, 2008. In the revised plans, please show a project area line establishing the area that is covered under this permit. In particular, please show whether or not the area labeled as "future development" in hatched lines on the August 22, 2008 plans is included in this permit. 3.) Deed Restrictions: a. Lot Summary: Please submit the information required by the enclosed table which summarizes which lots drain to each drainage area, the BUA per lot, the total BUA in each drainage area for all of the lots in the drainage area, and that the total BUA in each drainage area for all of the lots equals the total permitted BUA for each drainage area. If the lot numbers in the enclosed table need to be revised, please do so. b. Deed Restrictions: Please submit a copy of the recorded deed restrictions containing all of the required statements as listed in the current permit. If lot number have been revised such that the deed restrictions need to be revised please do so and submit the most current recorded deed restrictions. 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 May 19, 201 G, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee.

The overall BUA is maintained at the same amount as was permitted (1,748,918sf). In DA112,535sf of BUA is moving from "future" to "streets". And, in the "overall" totals, the clubhouse (6,707sf) and parking (5,832sf) have been removed and this BUA has been transferred to future. Can you confirm that these are the only changes and that there are no other changes being proposed that would affect the permit text. (Such as the # of lots is staying the same, you aren't adding or removing drainage area, you aren't doing any changes to the design of any of the ponds; etc). If so, then we will return the check and process this as a plan revision.

The original permit included the impervious area for the proposed clubhouse. We are now also proposing a pool, tennis court and parking area. The additional impervious amount has been taken out of the impervious area listed as "future" on the original permit. Therefore there is no net change to the total impervious area permitted and no change to the design of the pond. Enclosed please find two (2) sets of plans, one (1) signed original and one (1) copy of the application form with narrative, a wet detention basin supplements, operation and maintenance agreement, (2) sets of calculations and one check for the application fee. Please review for approval and contact us with any questions, comments or if you need additional information. Thank you. Sincerely, Tripp Engineering, P.C. Larry Knoerl LDK:dcb Enc. r'ZECEIVED MAR 0 5 2010 BY: March 04, 2010 Stormwater Narrative The Village at Mott's Landing - Amenities Area New Hanover County, NC TE 03060A The Village at Mott's Landing — Amenities Area is an existing vacant 2.88 acre tract proposed for use with a clubhouse, pool, tennis Court and parking area. The location of this Amenities Area replaces the one previously designed for this project. Stormwater drainage from the Amenities Area will drain to Wet Detention Basin #1. The change in location of this area has no affect on the previous design of Wet Detention Basin #1 since the amount of the total drainage area and impervious area remains the same. Wet Detention Basin #1 was designed as high density and treated by wet detention. This pond was designed to meet the State's 1" and the County's 25-year pre -post requirement. Outflow from all ponds drains to Mott's Creek, classification C-SW.
