Subject: Swartville Residential- Preliminary Plan TRC Review
Technical Review Committee (TRC) General Information
The TRC is a staff-level group of local government officials that reviews projects for compliance with
the local regulations administered by each respective review agency. Voluntarily participating state
agencies may also provide comments. And general information and non-binding recommendations
about the site may also be provided by government agencies.
The TRC meetings are considered staff meetings and are not public hearings. The TRC meeting is an
opportunity for applicants to speak with county staff and any voluntarily participating state or
federal agencies about the review comments they have been provided.
No voting is involved in the TRC process, and no final approvals or denials are made at the TRC
meetings. Following the TRC meeting, applicants are responsible for updating their plans to address
review comments. Those revised plans need to be resubmitted to the assigned case planner. The
case planner will facilitate additional reviews until all comments have been addressed, and the
necessary departments have stated the plans comply with the applicable minimum requirements
for development.
Following any future TRC approval, the project is required to obtain additional permits to include a
zoning compliance permit for the site. Applicants are also responsible for coordinating with state
and federal agencies for compliance with any additional requirements. Any activity on the property
that is not approved as part of the TRC review and zoning compliance permit will be considered a
violation of the UDO and subject to enforcement action under Article 12 Violations and
Enforcement.

The following comments have been received for the February 4, 2026, TRC meeting. Additional
comments may be made upon further review of subsequent revisions.
Planning, Zach Dickerson, zdickerson@nhcgov.com
Compliance with local zoning requirements
1. General Comments
a. The zoning on this site is R-7, tied to rezoning case Z23-02. It is a straight rezoning
with no conditions.
b. This is a performance residential subdivision.
i. The R-7 district allows a maximum 6 dwelling units per acre.
ii. There are Class IV soils on this site which are not being set aside for density
purposes. Those numbers are broken out below.
iii. Density Calculations:
1. Total site acreage = 89.9 acres
2. Less 11.3 acres of Pamlico Muck Soil.
3. R-7 Zoning District allows maximum of 6 dwelling units per acre
under performance residential subdivision.
4. 78.6 acres * 6 dwelling units per acre = 472 maximum dwelling units
5. This project only shows 241 lots, less than the maximum allowable.
c. Staff recommend including the location of traffic calming devices on the preliminary
plans. Installation of traffic calming devices are not required, but including potential
locations on the plan ensures the future HOA / owners will have the opportunity to
install them without conducting a traffic study.
2. UDO Section 5.1, Parking and Loading
a. Single-family dwellings, detached, require 2 parking spaces per unit. Generally this is
achieved in the driveways. Please confirm each dwelling unit will have at least 2
parking spaces.
3. UDO Section 5.2, Traffic, Access and Connectivity
a. Please note that no building permit for any structure shall be issued which requires
NCDOT approval for a Driveway Permit until NCDOT has issued the permit approval.
Evidence of approval shall accompany the application for building permit.

b. I will get into this more in the Subdivision Design, but please detail how the
development will connect out to Castle Hayne Road. It shows a stub road currently,
but it would be helpful to see a zoomed out site plan that shows the road connecting
out to Castle Hayne.
c. We discussed this on the phone, but please detail how the stub road to the south will
connect to the Old Mill neighborhood, if such a connection is planned.
d. See WMPO’s comments about a TIA- most of these details will likely get ironed out in
the TIA.
4. UDO Section 5.3, Tree Retention
a. Note: Land disturbance permits can be issued by county Engineering before a Tree
Removal Permit is approved by Planning. However, any trees removed before the
Tree Removal Permit is issued may result in enforcement action under Section 5.3.2
of the Unified Development Ordinance to include prohibiting any development of
the site for 3 to 5 years.
b. Tree Removal Permits are not required for residential lots of less than one acre in
size if they are shown as part of an approved preliminary plan.
c. Please note that a Tree Removal Permit will be required for essential site
improvements, such as roads and stormwater infrastructure.
5. UDO Section 5.4, Landscaping and Buffering
a. Landscaping and buffering are only required for the amenity areas, if any are
planned.
6. UDO Section 5.5, Lighting
a. Please note under 5.5.2.A that a lighting plan is not required for single-family
residential projects and the county does not require streetlights, however a lighting
plan is required for any amenity area.
7. UDO Section 5.6, Signs
a. No signs are shown on the plan. However, if any are planned, please ensure you
submit for a sign permit and that they are outside of the NCDOT sight triangles on
Castle Hayne Rd.
b. For any signs on the site, a separate sign permit must be submitted and reviewed by
the county for compliance with Section 5.6 of the UDO for standards at or after the
submittal of the separate zoning compliance and construction permits for the
primary building or use.

8. UDO Section 5.7, Conservation Resources (COD)
a. Per the New Hanover County Conservation Resources Map, there is a large area of
the Pocosin Conservation Resource on this site.
i. A rough measurement using New Hanover County GIS shows approximately
76.8 acres of the site is Pocosin Conservation Resource. I have included a
screenshot below showing what our records show.
Pocosin Conservation Resource
ii. Table 5.7.2.A states that Pocosin areas greater than 5 acres in size are
regulated, and Conservation Resource Standards kick in.
iii. However, a historic staff determination states that Pocosin Conservation
Resources, specific to only Pocosin, kick in when they are underlaid with
Class IV soils.
Swartville Residential – Major Subdivision – TRC Review
Page | 5
iv. As indicated in the application, there are 11.3 acres of Pamlico Muck soil on
the site. I have included a screenshot below, similar to the one above,
showing the areas on the site that our maps show there is Pamlico Muck soil.
Pamlico Muck Soil (Pm)
v. The way the required conservation space would be calculated out is as
follows:
1. Field verification of the exact acreage of Class IV soils that underly the
Pocosin Conservation Resource. In this case, we can use 11.3 acres as
an example.
2. The 11.3 acres of Pamlico Muck underlies the Pocosin Conservation
Resource, indicating this is an area that would trigger COD
requirements. This translates to 11.3 acres of Pocosin COD.
3. Table 5.7.3.A.5 shows how to calculate required Conservation Space.
4. 11.3 acres * .5 Conservation Space Factor = 5.65 Acres of required
conservation space.
Swartville Residential – Major Subdivision – TRC Review
Page | 6
vi. Please refer to UDO Section 5.7.3.E for methods of setting aside
Conservation Space.
vii. All structures must be set back at least 25 feet from the Conservation Space
Area.
9. UDO Section 5.8, Open Space Requirements
a. Total site acreage is 89.90 acres.
b. Performance Residential Developments require 20% open space.
c. Site plan shows open space at 26.89 acres. This is approximately 30% open space,
exceeding the minimum requirements.
10. UDO Article 6, Subdivision Design and Improvements.
a. The R-7 district requires sidewalks on both sides of the street.
i. The site plan itself appears to show sidewalks on both sides of all streets, but
the road cross section only shows sidewalks on one side.
b. Block lengths are all less than 1000’ ft, block length is compliant.
c. Site plan shows 16 links and 11 nodes, meeting a link to node ratio of 1.45. This is
sufficient.
d. It appears that the streets in between lots 126-141|162-175, 190-176|191-204, and
218-205|61-44 (the eastern side of the development) are much narrower than the
streets in the other parts of the development. Are these intended to be more
narrow?
e. It appears that the travelway width of the roads is only 20’- per the New Hanover
County Private Roadway Design Manual for Private Roads, the travelway needs to be
at least 24’ in width.
f. The ROW width is sufficient at 50’.
11. UDO Article 9, Flood Damage Prevention
a. None of this property is in the floodplain.

NHC Fire Services, Ray Griswold 910-798-7448
Compliance with the NC Fire Code
1. This is a preliminary review only for PHASE # 1
2. Additional fire hydrants will be required. You show only show 3
3. Fire hydrants are required at each entrance to the project. The 1,000 foot rule is not as the
crow flys, it is measured by driving distance. I do see small dots, are these additional ones???
4. Where will the water access be coming from?
5. No gates or traffic calming devices allowed unless identified.
NHC Engineering, Galen Jamison 910-798-7072
Stormwater management and land disturbance
1. A County stormwater and land disturbing permit issued by the County is required for this
project. Please digitally submit the permit applications documentation with requisite review
fees to the COAST online permit portal (https://newhanovercountync-
energovpub.tylerhost.net/apps/selfservice#/home). Applicable forms can be found at
https://www.nhcgov.com/251/Stormwater-Permitting and
https://www.nhcgov.com/249/Sediment-Erosion-Control.
2. Page 5 of the application, item 15, indicates the need to show all proposed stormwater and
drainage facilities on the site plan. This information will need to be shown prior to
Engineering providing approval for TRC. Please ensure the SCM outfall locations are
identified, 10’ access along the top of the SCMs are provided for maintenance, how the
emergency spillway will outfall for SCM pond A, and how roadside drainage is anticipated.
3. Please contact the State for their stormwater permit requirements. It is anticipated a new
high density permit will be required.
NHC Environmental Health, Dustin Fenske 910-798-6732
Septic tanks and wells
1. Subdivision must connect to public water and sewer. Lots do not appear large enough to
support well and septic systems.
2. Site plan does not appear to reflect any setback issues to well or septic systems (more
details is needed.)

NHC Addressing, McCabe Watson 910-798-7068
Street naming and property address
1. Please submit street name proposals with alternatives to be approved prior to TRC approval.
2. Please contact me for address assignments following TRC approval.
Cape Fear Public Utility Authority, Bernice Johnson 910-332-6620
Public water and sewer
1. CFPUA TRC Comments provided are preliminary comments only.
2. Utility Plan Review required by CFPUA. CFPUA is moving toward becoming paperless. When
ready to submit plan review package, upload all documents to
https://www.cfpua.org/FormCenter/Engineering-3/Engineering-Plan-Review-103.
3. CFPUA water will require a mainline extension.
4. Sewer will require design, permitting, and construction (at the Developers Expense and to
CPFUA Standards) a public Regional Pump Station and Force Main That Discharges Into
Existing Force Main (see attached map)
5. CFPUA Meter Sizing Form will be required.
6. Capacity is dependent on the analysis of the pipe collection system (gravity and force mains).
7. A capacity determination can be provided upon submittal of the NC DWQ FTA/FTSE
Application Form and a Preliminary Plan, this determination does not guarantee capacity.
8. Capacity is issued to projects on a first come, first serve basis, when capacity is available, the
plans meet Authority requirements, and the NC DWQ FTA/FTSE forms are signed by the
Authority.

Army Corps of Engineers, Brad Shaver 910-251-4611
Requirements if wetlands are impacted
1. This proposed development will impact both wetlands and jurisdictional ditches and require
permitting, likely an individual permit as impacts appear to be greater than 0.5 of an acre.
The phase 2 portion of the development has not received a jurisdictional determination to
date. This site has seen on-site restoration which was closed out in August 2024 through
enforcement procedures.
