ZONING DISTRICTS
These maps show the location of various zoning districts in
relation to landmarks such as street centerlines, property lines,
utility right of ways, etc.
The zoning district boundaries are drawn to conform as
accurately as possible with the Official Zoning Maps of the City of
Wilmington and New Hanover County, which are located in their
respective planning departments. However, determinations as to
the precise location and status of any zoning district boundary rest
with the official maps, as interpreted by the appropriate City or
County Building Inspector.
For information regarding permitted uses and building
restrictions associated with each district, consult the Zoning
Ordinance of the City of Wilmington or the Zoning Ordinance of
New Hanover County, also available from the respective city or
county planning departments.
NOTE: The example shown in this guide depicts the zoning
for that area at the time this publication went to
press. Alterations to the zoning configuration shown
may have occurred since that time. The actual
zoning map print you receive will reflect current
zoning districts and configurations.

WATERSHEDS/
DRAINAGE DIVIDES
Dotted lines on these maps indicate the general location of a
major drainage divide in relation to recognizable landmarks such
as streets, utility right of ways, water bodies, etc. Each drainage
divide represents the boundary between two of the watersheds in
the County. The maps can be used to identify the specific creek to
which stormwater runoff from a given area will likely flow. The
potential impacts that a proposed land development may have on
downstream flooding, estuarine water salinity and quality, stream
sedimentation, etc. in any given creek can be better understood
through use of the maps.
NOTE: To keep the total number of overlays in the mapping
system at a minimum, drainage divides are shown on
the same overlay as flood hazard areas.

SEPTIC TANK SUITABILITY
Shaded areas on these maps indicate different levels of soil
suitability for waste disposal using septic tanks. The classification
system is as follows:
Unshaded
Class I soils
Suitable or slight limitation
for septic tanks
Light
Class II soils
Moderate limitation; moderate
Shaded areas
modification and maintenance
necessary for development
Medium
Class III soils
Severe limitation; extensive modifi-
Shaded areas
cation and intensive maintenance
required for development
Dark
Class IV soils
Unsuitable; generally not economically
Shaded areas
feasible or environmentally desirable
to develop.
For a listing of the general soil units that fall within each
suitability class, and the factors which determine each class, the
Classification of Soils in New Hanover County for Septic Tank
Suitability, available at the New Hanover County Planning
Department, should be consulted.
The classification system is designed to assist in determining
the general suitability of an area for development using septic
tanks. The classification system is not, however, intended to
supersede any on -site soil evaluations required by the New
Hanover County Health Department, or any other agency.

PROPOSED THOROUGHFARES overlay

PROPOSED
THOROUGHFARES
Shaded areas on these maps represent the general alignment
of proposed transportation facilities. Solid shading indicates that
improvements are proposed or have been made to an existing
facility. (In some cases, planned improvements may include the
acquisition of additional right of way to widen the facility). Broken
shading indicates the general alignment of a proposed new facility.
The precise location of new facilities is subject to change based
upon a number of factors including: topographic and other design
concerns, environmental, historical, and archaeological concerns,
the location of existing development, and the type of facility to be
constructed.
At -grade intersections, those where two roads meet at the
same level, are indicated by solid -shaded circles. Separated -grade
intersections, where an overpass or cloverleaf is typically involved,
are represented by unshaded circles.
For further information regarding the status of any proposed
facility, contact:

C71PFRIMARY AQUIFER
RECHARGE AREAS
The heavy dashed line indicates the general extent of the
County's primary aquifer recharge area. Large "R's" are used to
identify the side of the line to which the recharge designation
applies.
Groundwater resources are replenished or "recharged" by
local rainfall virtually everywhere in New Hanover County.
However, the primary aquifer recharge areas identified are
extensive land areas having topographic, soil and geologic
conditions which are generally excellent for the infiltration of
rainfall into the Castle Hayne limestone and Pee Dee sandstone
aquifers. In general, these areas may be characterized by several
or all of the following: a high artesian water level (also known as a
potentiometric surface), a relatively high, level ground elevation,
little or no natural surface drainage via streams, and well water
which has lower chloride and higher iron and hardness values.

OCEAN ERODIBLE AREAS
Ocean erodible areas are stretches of barrier island beach
where there exists a substantial possibility of excessive erosion
and significant shoreline fluctuation. The seaward boundary of
these areas is the mean low water line. The landward extent of the
ocean erodible area for each stretch of beach is measured from the
first line of stable natural vegetation or erosion escarpment, and is
listed as a distance on the Ocean Erodible Area Map. Brackets are
used to show the stretch of beach to which the standard applies.
Due to the constantly changing position of the first line of stable
vegetation, it is not practical to actually draw the landward extent
of ocean erodible areas on the maps. The precise location of the
landward boundary must be measured on -site from the current
line of vegetation.
For information regarding restrictions on development within
these areas, and the manner in which they are determined,
contact:

NOTE: To keep the total number of overlays in the mapping
system at a minimum, ocean erodible areas are
shown on the same overlay as flood hazard areas.

C7GENERAL SOILS
These maps show the general location of soil units in relation
to recognizable landmarks, such as streets, utility right of ways,
water bodies, etc.
The soil maps are useful as a general land planning aid in the
layout of streets, the location of buildings and utilities, and other
uses. It is important to note, however, that small areas of
contrasting soils may occur within the areas identified on the
maps, and the actual extent of the soils may vary somewhat from
the boundaries drawn.
Soil boundaries depicted on these 1" = 400' maps conform
with those shown in the 1" = %4 mile Soil Survey of New Hanover
County, North Carolina (April 1977), published by the USDA Soil
Conservation Service. For information regarding the suitability
and specific limitations of each of the soil mapping units for various
purposes, the Soil Survey should be consulted.

FLOOD HAZARD AREAS
The wavy pattern on each flood hazard area map indicates
the extent of the "100 year flood", also known as the "base flood".
This is a storm event which has a probability of occurring once in
one hundred years.
These flood hazard area maps are intended for use as a
general land planning aid only. The official Flood Hazard
Boundary Maps and Flood Insurance Rate Maps for the City of
Wilmington and New Hanover County are located in the
respective offices of the City and County Building Inspector.
Where a determination is needed as to the exact location of the
boundaries of areas of special flood hazard, the City or County
Building Inspector (as appropriate), should be contacted for
further direction.

PLANNING MAP
Planning maps show lots, streets, railroads, waterways, and
other natural and man-made features. They also serve as the
mapping base for the entire overlay series. Drawn at a scale of 1" _
400', the maps are useful for a variety of land planning purposes,
especially when used in combination with the overlay series (see
examples on following pages). However, for any specific property
ownership or tax -related information needs, the official tax maps
of New Hanover County, located in the New Hanover County Tax
Office, County Administration Building, 320 Chestnut Street,
should be consulted.

HOW TO USE THIS GUIDE.
This guide has been prepared to inform the public of the availability of land planning
maps from the Wilmington Planning Department. As shown on the opposite page, the
mapping system divides the County into 96 "planning maps". These planning maps, each
covering approximately 2200 acres, display the division of land into parcels, and the
location of streets, railroads, waterways, and other major features. Each planning map has
a series of overlays which depict various types of information relating to land development.
The overlay series consists of:
1) Flood Hazard Areas
2) General Soils
3) Ocean Erodible Areas
4) Primary Aquifer Recharge Areas
5) Proposed Thoroughfares
6) Septic Tank Suitability
7) Watersheds and Drainage Divides
8) Zoning Districts
Small-scale examples of each of these overlays are provided on pages 5 through 20.
The actual maps available are at a scale of 1" = 400', and measure 24 x 36 inches in size.
To obtain the mapped information you desire, follow these steps:
1) Locate the area for which you desire information on the "Index to Planning
Maps" (opposite page) noting the appropriate map numbers.
2) Select the type of map overlay you desire from the list above.
3) Call: 762-8734 or
Write: Wilmington Planning Department
P.O. Box 1810
19 North Fifth Street
