CONSERVATION, HISTORIC, & ARCHAEOLOGICAL RESOURCES
Conservation
The County’s Conservation Resources Map indicates that swamp forest may
be present on the site. Conservation space is required for swamp forest
when at least five acres of the resource exists on the property. Verification
of regulated swamp forests and pocosin wetlands will be required during
the site plan review process.
Historic No known historic resources
Archaeological No known archaeological resources
ZONING CONSIDERATIONS
• The applicant is proposing to rezone approximately 117.58 acres from R-20 to R-15.
• The subject site is bisected by the I-140 right-of-way, which is constructed above grade.
• The subject site consists of three parcels bordering the Walnut Hills subdivision to the east.
Adjacent zoning includes Planned Development (PD), R-15, R-10, and R-20. There is also I-
2 west of the site, across the Northeast Cape Fear River.
• Because this is a straight rezoning, a conceptual plan is not included as part of the
application and site specific conditions cannot be placed as part of a rezoning approval.
The subject site would be required to meet all of the Unified Development Ordinance’s
(UDO) requirements for development within the R-15 district.
• Dimensional differences for the current R-20 and proposed R-15 districts are outlined in the
chart below.

Performance
Subdivision
Density 1.9 du/ac 2.5 du/ac
• The majority of uses are consistent between the two districts with the exceptions of duplexes
and mobile homes require a special use permit in the R-20 district and are permitted by
right in the R-15 district. Also, the rezoning to R-15 would allow for a mobile home park,
Z21-12 Staff Report BOC 11.1.2021 Page 4 of 14
convenience store, and fuel sales to be developed with a special use permit, though
residential uses are typical in both districts.
• The subject site is partially located within the Special Highway Overlay District (SHOD).
Any building constructed within the SHOD limits would be required to be set back 25’ from
any property line and subject to a maximum lot coverage of 50%.
• Any proposed development would be reviewed by the Technical Review Committee (TRC)
to ensure compliance with applicable County and State regulations, including applicable
site design and approval provisions within the UDO.

TRANSPORTATION
Access
• Access will be provided to the subject site, east of the NC I-140, by Rockhill Road, a local
street. Access to the subject site, west of NC I-140, will be provided access off Alvernia
Drive, a local street.
• Traffic Impact Analyses (TIAs) are not required for a straight rezoning, as a specific
development proposal is required to thoroughly analyze access, potential trip generation,
and roadway improvements.
• Before any development can occur on this site, the Technical Review Committee will review
all plans for compliance with applicable land use regulations, including any recommended
roadway improvements from traffic impact analyses to ensure adequate traffic safety and
Z21-12 Staff Report BOC 11.1.2021 Page 6 of 14
distribution. Recommended roadway improvements will be completed as required by a TIA
or through the NCDOT Driveway permitting process.
• Due to environmental constraints on the subject property, current zoning would permit up to
79 dwelling units at 1.9 du/ac under the performance residential standards. A development
of this scale is estimated to generate between 61 and 81 trips during the peak hours. The
proposed rezoning would increase density to a maximum of 104 dwelling units at 2.5 du/ac
under the performance residential standards. A development of this scale is estimated to
generate between 79 and 105 trips during the peak hours.
Development Intensity Approx. Peak Hour Trips
Existing Zoning (R-20): 79 dwelling units
61 AM/81 PM
Proposed Zoning (R-15): 104 dwelling units
79 AM / 105 PM
25 dwelling units + 18 AM / + 24 PM
• Because a traffic impact analysis (TIA) is not required to analyze transportation impacts at
this time, staff has provided the volume to capacity ratio for the adjacent roadway near
the subject site. While volume to capacity ratio, based on average daily trips, can provide
a general idea of the function of adjacent roadways, the delay vehicles take in seconds to
pass through intersections is generally considered a more effective measure when
determining the Level of Service of a roadway.

Nearby Planned Transportation Improvements and Traffic Impact Analyses
Nearby NC STIP Roadway Projects:
• STIP Project U58-63: A multi-lane widening project is scheduled along NC -133 (Castle Hayne
Road), from I-140 to SR 1310 (Division Drive). The Right-of-way acquisition is expected to
occur in 2025.
Nearby Traffic Impact Analyses:
Traffic Impact Analyses are completed in accordance with the WMPO and NCDOT standards. Approved
analyses will expire if the proposed development is not completed by the build out date established within the
TIA.
There are no traffic impact analyses located within the typical one mile buffer.

ENVIRONMENTAL
• The site does contain AE Special Flood Hazard Areas.
• The subject property is located within the Dock Creek watershed.
• Per the Classification of Soils in New Hanover County for Septic Tank Suitability, soils on the
property consist of Class I (Suitable/slight limitation) soils, Class II (moderate limitations),
and Class III (Severe limitations) soils.
• The southern corner of the subject site appears to Staff to contain wetlands, and the County’s
Conservation Resources Map indicates that swamp forest areas may be present on the site.
Conservation space is required for swamp forest when at least five acres of the resource
exists on the property. Verification of regulated swamp forest area will be required during
the site plan review process. If the site is deemed to contain a regulated resource,
regulations can impact building envelope, limit density, and require additional setbacks.
OTHER CONSIDERATIONS
SCHOOLS
• Students living in the proposed development would be assigned to Castle Hayne
Elementary, Holly Shelter Middle, and Laney High School. Students may apply to attend
public magnet, year-round elementary, or specialized high schools.
• Under the current zoning, density would be limited to a maximum of 79 dwelling units. A
maximum of 104 units could be developed under the proposed rezoning.
• Based on the current general student generation rate*, the increase in homes would result
in approximately 6 additional students than would be generated under current zoning.
• The general student generation rate provides only an estimate of anticipated student
yield as different forms of housing at different price points yield different numbers of
students. Over the past four years, staff has also seen a decline in the number of students
generated by new development. Student numbers remained relatively stable between
2015 and 2020 (excepting the impacts of COVID-19pandemic), while 14,500 new
residential units were permitted across the county. In addition, the student population is
anticipated to only grow by approximately 1,300 students over the next 10 years based
on the recent New Hanover County Schools Facility Needs Study.

*The current general student generation rate was calculated by dividing the projected New Hanover County public school student
enrollment for the 2021-2022 school year by the number of dwelling units in the county. Currently, there are an average of
0.22 public school students (0.09 for elementary, 0.05 for middle, and 0.08 for high) generated per dwelling unit across New
Hanover County. These numbers are updated annually and include students attending out-of-district specialty schools, such as
year-round elementary schools, Isaac Bear, and SeaTech.
**Because the student generation rate often results in fractional numbers, all approximate student generation yields with a
fraction of 0.5 or higher are rounded up to a whole number and yields with a fraction of less than 0.5 are rounded down. This
may result in student numbers at the elementary, middle, and high school levels not equaling the approximate total.
• Given the size of the proposed development, it may have a build-out date within 5 years,
so staff has outlined existing school capacity to provide a general impact of the potential
impact on public schools. These numbers do not reflect any future capacity upgrades that
may occur over the next five years or trends in student population changes.

* Enrollment is based on the New Hanover County Schools enrollment that was projected for the 2021-2022 school
year.
**Capacity calculations were determined based on the projected capacities for the 2021-2022 school year, and
funded or planned capacity upgrades were those included in the Facility Needs Study presented by New Hanover
County Schools to the Board of Education in January 2021. This information does not take into account flexible
scheduling that may be available in high school settings, which can reduce the portion of the student body on campus
at any one time.
• The recent facility needs survey that has been prepared by Schools staff indicates that,
based on NC Department of Public Instruction (DPI) student growth projections and school
Z21-12 Staff Report BOC 11.1.2021 Page 9 of 14
capacity data, planned facility upgrades, combined with changes to student enrollment
patterns, will result in adequate capacity district wide over the next five years if facility
upgrades are funded.

CONTEXT AND COMPATIBILITY
• The property is bisected by NC I-140, which is built above grade.
• Higher density residential projects are anticipated for vacant properties along major
roadways where they can can serve as a transition between the roadway and existing
single-family neighborhoods.
• There is a variety of zoning in the area, including R-15 and R-20 to the north. There is also
I-2 to the west, across the Northeast Cape Fear River, and R-10 to the east. The development
pattern in this area has continued to evolve over the last few years; at one time this area
was all zoned R-20.
• The intent of the R-15 district is to serve as a transition between very low-density residential
development patterns and smaller lot, more dense residential areas of the County.
• As part of the application materials, the applicant provided a conceptual plan illustrating
the envelopes of the site that are developable given the environmental constraints. While
this is a general rezoning and approval cannot be tied to a site-specific plan of
development, the conservation resources will limit density and impact product design.
2016 COMPREHENSIVE LAND USE PLAN
The New Hanover County Future Land Use Map provides a general representation of the vision for
New Hanover County’s future land use, as designated by place types describing the character and
function of the different types of development that make up the community. These place types are
intended to identify general areas for particular development patterns and should not be
interpreted as being parcel specific.
Z21-12 Staff Report BOC 11.1.2021 Page 12 of 14
Future Land Use
Map Place Type General Residential and Conservation
Place Type
Descriptions
General Residential
Focuses on lower density housing ranging up to approximately 8 du/ac,
typically consisting of single-family or duplexes. Types of appropriate uses
include single-family residential, low-density multi-family residential, light
commercial, civic and recreational.
Conservation
Covers areas of natural open space and are intended to protect the natural
environment, water quality, and wildlife habitats. They serve the public
through environmental education, low-impact recreation and in their natural
beauty. Protection may also extend to important cultural or archaeological
resources and to areas where hazards are known to exist.
Analysis
The subject site is located in an area the Comprehensive Plan generally
envisions as General Residential, though places close to the Cape Fear River
where environmental constraints are likely are designated as Conservation.
The intent is to reflect the existing residential development pattern while
protecting natural resources.
While increased density is not encouraged in Conservation place types, the
Comprehensive Plan is a bubble plan, so the boundaries between place
types are flexible. More technical information, such as resource type and
official delineations, is important to establish the actual line between
Conservation and adjacent General Residential areas. In addition, there are
code provisions that allow for a maximum density of 2.5 dwelling units per
acre in areas paired with a Conservation place type and R-15 zoning. The
exhibit included in the applicant’s materials indicates a significant amount
of wetlands are located on the property that would reduce the buildable
envelope.
The site is bisected by the NC I-140 interchange and is immediately
adjacent to a variety of residential zoning. The northern properties contain
R-15 and R-20 zoning. There is an R-10 subdivision to the east and the
Northeast Cape Fear River to the west.
The requested R-15 rezoning could allow for the types of uses that could be
appropriate in this area, and R-15 is one of the typical zoning categories
identified for the General Residential and Conservation place types.
Consistency
Recommendation
The proposed R-15 rezoning is generally CONSISTENT with the
Comprehensive Plan because it allows the types of uses recommended in the
General Residential and Conservation place types and is identified as a
typical zoning category in both place types.

PLANNING BOARD MEETING
The Planning Board considered this application at their October 7, 2021 meeting. No one spoke
in support of or in opposition to the request. The Planning Board recommended approval of the
petition (6-0).
The Planning Board found the application to be CONSISTENT with the purposes and intent of the
Comprehensive Plan because the district allows the types of uses that would be encouraged in the
General Residential and Conservation place types and would serve as an appropriate transition
between the river, interstate, and adjacent residential neighborhoods.
The Planning Board also found APPROVAL of the rezoning request is reasonable and in the
public interest because the site is located in an area with a variety of zoning districts and
densities and will be restricted due to the environmental constraints.
Z21-12 Staff Report BOC 11.1.2021 Page 14 of 14
STAFF RECOMMENDATION
Staff concurs with the Planning Board’s recommendation and suggests the following motion:
I move to APPROVE the proposed rezoning to an R-15 district. I find it to be
CONSISTENT with the purposes and intent of the Comprehensive Plan because the
district allows the types of uses that would be encouraged in the General Residential
and Conservation place type and would serve as an appropriate transition between
the river, interstate, and adjacent residential neighborhoods. I also find APPROVAL of
the rezoning request is reasonable and in the public interest because the site is located
in an area with a variety of zoning districts and densities and will be restricted due to
the environmental constraints.
Alternative Motion for Denial
I move to DENY the proposed rezoning to an R-15, Residential district. While I find it
to be CONSISTENT with the purposes and intent of the Comprehensive Plan because
the district allows the types of uses that would be encouraged in the General
Residential and Conservation place types and would serve as an appropriate transition
between the river, interstate, and adjacent residential neighborhoods, I find DENIAL
of the rezoning request is reasonable and in the public interest because the proposal
is not consistent with the desired character of the surrounding community and the
intensity of the uses allowed within the proposed district will adversely impact the
adjacent neighborhoods.
