Deed restrictions and protective covenants are necessary to ensure that the development maintains a "built-upon" area consistent with the design criteria used to size the stormwater control facility. I, Libby Shelton , acknowledge, affirm and agree by my signature below, that I will cause the following deed restrictions and covenants to be recorded prior to the sale of any lot: 1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number , as issued by the Division of Energy, Mineral and Land Resources under the Stormwater Management Regulations. 2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the stormwater management permit. 3. These covenants are to run with the land and be binding on all persons and parties claiming under them. 4. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Energy, Mineral and Land Resources. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Energy, Mineral and Land Resources. 6. The maximum allowable built-upon area per lot is 4,000 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. 7. Each lot will maintain a 50**foot wide vegetated buffer between all impervious areas and surface waters. 8. All runoff from the built-upon areas on the lot must drain into the permitted system. This may be accomplished through a variety of means including roof drain gutters which drain to the street, grading the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them into a component of the stormwater collection system. Lots that will naturally drain into the system are not required to provide these additional measures.

Existing Site The project is located in New Hanover County, 1.80 miles North East of the intersection of Blue Clay Road (SR 1318) and Sidbury Road(SR 1336).The proposed 314.3 acre development,known as Sidbury Farms is a performance residential subdivision with a total of 655 single family homes (258 in Phase 1, 163 in Phase 2 and 234 in Phase 3) and 103 townhomes (59 in Phase 2 and 44 in Phase 3). Sidbury Road (SR 1336)has a 100-foot Right of Way with two 12-foot travel lanes,minimal paved shoulders and existing roadside ditches that vary in base width and depth. The roadside ditches are heavily overgrown with vegetation and drain towards Prince George Creek. A copy of the USGS quadrangle map is attached indicating project vicinity and general drainage patterns in the area. The project site is in the Cape Fear River Basin. According to the latest surface water classifications published by NCDEQ Prince George Creek is classified as C;Sw. Prince George Creek Drains to the North East Cape Fear River(B;Sw,Index-No. 18-74-(47.5)) as illustrated on the attached USGS Topo Map. The site does not drain to ORW designated waters,is not within -mile of and draining to SA classified waters and is not within 1-mile and draining to I IWQ designated waters. II.Proposed Improvements This addendum to the current permit addresses only the off-site drainage related to the widening of Sidbury Road. No changes to the on-site drainage areas or stormwater control measures(SCM's) as currently approved are proposed.Through previous coordination with the NCDOT District 3 Office on the TIA prepared for project,the developer is required to establish a right in/right out driveway at Site access#1 and a symmetrical widening of Sidbury Road (SR1336) to establish left and right turn lanes into the proposed development at Site Access#2. Only Site Access #1 and Site Access#2 are proposed at this time of permit modification. To avoid future lengthening of these improvements,they are being built to the dimensions required for full build-out of the development. The proposed roadway within the right of way is a shoulder section and will follow existing drainage patterns via roadside swales. Existing Stormwater Runoff from Sidbury Road and adjacent properties is currently conveyed through existing roadside ditches.These ditches will be relocated to accommodate proposed roadway improvements while maintaining existing drainage patterns. The ditches will be improved to accommodate the proposed runoff and meet current NCDOT Design Criteria and Velocity and Depth of treatment swales. The proposed roadside ditches have been verified to accommodate post construction stormwater runoff from the 10-year storm event and are less than 2.0%grade. The table below provides a break down on the proposed and existing BUA for the project area.

Kellie- We wish to pursue the second option listed below. I have now spoken with the co-permittees and current landowner and they are all in agreement with this approach. Do I need to send you anything else to get this scheduled? The only thing I can think of is a new request form with John Rudolph listed so that you have an express request from each of the current co-permittees. I understand that on our express submittal date we will need to have the modification package as well as the transfer of ownership forms/package, Thank you for your patience while we worked this out with the parties on our end.

So there are a few options,one of them being sending a transfer package into the Regular program(transfers are not done in the Express program.) Once the permit is transferred, it can then be modified by the new owner,Sidbury 758, LLC. Another option is to have the current permittee submit the major modification package as the applicant. This could go to the express program, be modified and then subsequently transferred in the regular program into the new owners name. If you choose the latter option, please note that both the medication package and the transfer package must be simultaneously submitted. Please let me know if you have any further questions.

Kellie- Sorry for the delay-I have been in Raleigh in corporate meetings the last 2 days. Based on the below, I believe modification to the existing permit is the best option-I didn't know we could still make hybrid permits with a low density portion in them. While NHC still shows RMP Sidbury,LLC and the landowner,the current landowner is Sidbury 758,LLC. I can provide documentation to this affect. I believe this also means I need to include a change of ownership form for the overall permit to be transferred to Sidbury 758, LLC. I will have both RMP Sidbury, LLC and D.R. Horton sign the transfer form as well as Sidbury 758, LLC. Sound good? Thank you for your help!

Typically,in this situation, it is preferred that instead of a new permit,the current permit for Sidbury Farms,SW8 200705,would be modified. The current permittees on this permit are DR Horton Inc.and RMP Sidbury Road LLC. Is Sidbury Road LLC still the current owner? If so,both permittees would need to be represented on the application and signatures from both would be required. This would be classified as a major modification and a low density section would be added to the current high density permit. If you wish to proceed this way, please provide an updated express request form and narrative.

Design Narrative I. Existing Site The project is located in New Hanover County,1.80 miles North East of the intersection of Blue Clay Road(SR 1318) and Sidbury Road(SR 1336).The proposed 314.3 acre development, known as Sidbury Farms is a performance residential subdivision with a total of 655 single family homes (258 in Phase 1, 163 in Phase 2 and 234 in Phase 3) and 103 townhomes (59 in Phase 2 and 44 in Phase 3). Sidbury Road (SR 1336)has a 100-foot Right of Way with two 12-foot travel lanes,minimal paved shoulders and existing roadside ditches that vary in base width and depth.The roadside ditches are heavily overgrown with vegetation and drain towards Prince George Creek.A copy of the USGS quadrangle map is attached indicating project vicinity and general drainage patterns in the area. The project site is in the Cape Fear River Basin. According to the latest surface water classifications published by NCDEQ,Prince George Creek is classified as C;Sw. Prince George Creek Drains to the North East Cape Fear River(B;Sw,Index-No. 18-74-(47.5)) as illustrated on the attached USGS Topo Map. The site does not drain to ORW designated waters,is not within lfz-mile of and draining to SA classified waters and is not within 1-mile and draining to HWQ designated waters. II.Proposed Improvements The proposed improvements for this project are provide primary and emergency access to the proposed development from Sidbury Road(SR1336).Through previous coordination with the NCDOT District 3 Office on the TIA prepared for project, the developer is required to establish a right in/right out driveway at Site access #1 and a symmetrical widening of Sidbury Road (SR1336)to establish left and right turn lanes into the proposed development at Site Access#2. To avoid future lengthening of these improvements,they are being built to the dimensions required for full build-out of the development.The proposed roadway within the right of way is a shoulder section and will follow existing drainage patterns in the roadside swales. Runoff from Sidbury Road and adjacent properties will be conveyed and treated through roadside swales designed to meet the Minimum Design Criteria as outlined in the NCDEQ Stormwater BM)Manual. The developer has obtained all local and state permits to allow onsite development of the Property and the location of the driveways are in accordance with the locations approved in the TIA for this project and by the County of New Hanover. The table below provides a break down on the proposed and existing BUA for the project area.
