Subject: Legacy Landing Phase 2- Preliminary Plan TRC Review
The following comments have been received for the June 18, 2025, TRC meeting. Additional comments
may be made upon further review of subsequent revisions.
Please note: following the TRC meeting, a revised preliminary plan addressing each of the items below
must be resubmitted before receiving preliminary plan approval.
Planning, Ryan Beil 910-798-7444
1. General Comments
a. Currently Conditionally Zoned R-10, housing type proposed are single-family detached
and single-family attached.
b. Phase II is a performance subdivision.
i. Density for Performance Residential: 3.1 dwelling units per acre within R-10 in a
Performance Residential Subdivision.
ii. There are no Class IV soils or wetlands on the property.
iii. Density calculations:
1. Total site acreage = 7.65 acres
2. R-10 Zoning District allows maximum 3.1 dwelling units per acre under
performance residential subdivision.
3. Developable site acreage (7.65) * zoning density (3.1) = 24 units
c. As this project was part of a conditional rezoning, the conditions on the site are as follows:
i. A six foot tall solid wood privacy fence shall be installed along the eastern
boundary of 1716 Rockhill Road also identified as New Hanover County Tax Parcel
ID R02500-003-102-000
ii. The permitted density range is 0 dwelling units per acre to a maximum of 3.1
dwelling units per acre. Planning staff is authorized to administratively approve
reductions in density within the permitted range.

iii. The housing types in the development shall be limited to detached single-family
dwellings and dual unit attached dwellings as defined in Section 2.3 of the Unified
Development Ordinance.
d. 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. Per table 5.1.2.A in the County UDO, there are 2 off street parking spots required for each
dwelling, which the site plan shows meaning the requirement is met.
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.
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. Are any trees planned to be removed for this project? If so, please apply for a Tree
Removal Permit: https://www.nhcgov.com/DocumentCenter/View/1239/Tree-Removal-
Permit-PDF
5. UDO Section 5.4, Landscaping and Buffering
a. Landscaping and buffering are only required for the amenity areas, however a listed
condition from this conditional rezoning requires a six foot tall solid wood privacy fence
shall be installed along the eastern boundary of 1716 Rockhill Road also identified as New
Hanover County Tax Parcel ID R02500-003-102-000.
b. Please show the location of the fence on the site plan to ensure the condition is met.
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, if any lighting is planned there.

7. UDO Section 5.6, Signs
a. There appears to be an area of open space near the entrance, please confirm if this will
be where the sign is placed.
8. UDO Section 5.7, Conservation Resources
a. Per the New Hanover County Conservation Resource Map there are no Conservation
Resources present on this property.
9. UDO Section 5.8, Open Space Requirements
a. There is .967 of an acre, or 42,129 square feet, of open space provided. The open space
requirement from our UDO in performance residential development is 20% of acreage,
which in this circumstance would equate to 24,219 square feet or .56 acres, meaning the
open space requirement has been met.
10. UDO Article 6, Subdivision Design and Improvements.
a. R-10 developments require sidewalks with a 5’ minimum width, please label them
sidewalks on the site plan.
b. Block length is below listed maximum of 1,000 ft.
c. Per the County UDO any subdivision shall achieve a connectivity ratio of no less than 1.40.
11. UDO Article 9, Flood Damage Prevention
a. No part of the property is in a flood zone.

MAP INFORMATION
The soil surveys that comprise your AOI were mapped at
1:15,800.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Soil Survey URL:
Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator projection, which
preserves direction and shape but distorts distance and area. A projection that preserves
area, such as the Albers equal-area conic projection, should be used if more accurate
calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as of the version date(s)
listed below.
Soil Survey Area: New Hanover County, North Carolina Survey Area Data: Version
26, Sep 9, 2024
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Nov 8, 2022—Dec 1, 2022
The orthophoto or other base map on which the soil lines were compiled and digitized
probably differs from the background imagery displayed on these maps. As a result,
some minor shifting of map unit boundaries may be evident.
TO: New Hanover County Planning Department, New Hanover SWCD, May 12th, 2025
FROM: Dru Harrison, Director
RE:
I HAVE REVIEWED THIS PLAN AS REQUESTED AND HAVE THESE COMMENTS: The
soils are predominantly Lynchburg fine sandy loam (Ls), Onslow loamy fine sand (On), and
Woodington fine sandy loam (Wo).
According to the booklet, “Wilmington/New Hanover Classification of soils for Septic Tank
Suitability Lynchburg, Onslow, and Woodington are Class II soils.
The Soil Survey of New Hanover County lists Lynchburg, Onslow as somewhat poorly drained,
and Woodington as poorly drained.
Woodington is on the New Hanover County Hydric Soils A list which means they are possibly
wetland areas and subject to regulation under the Clean Water Act. Lynchburg is on the Hydric
Soils B list, which means it may contain areas of wetland. It should be noted, according to the
Soil Survey of New Hanover County, the limitation for dwellings with or without basements and
for small commercial buildings is severe for all of the soils on this site. The limitations are due to
flooding and/or wetness. An adequate drainage and maintenance plan is needed for suitable
housing.
The U.S. Army Corps of Engineers has federal jurisdiction over 404 Permits and the
NCDEHNR, Dept. of Water Quality, has state jurisdiction over 401 Permits under the Clean
Water Act. Before disturbing possible wetland areas, developers should contact these agencies to
stay in compliance with State and Federal regulations.
