RE: Division of Coastal Management (DCM) Local Planning and Management Update
Dear Mr. Ulrich,
The following is a synopsis of the activities preformed by the Geographic Technologies
Group, Inc. in the summer and early fall on 1999. These activities are described in detail
in the document entitled "Hazard Mitigation Planning and Geographic Information
Systems (GIS) Enhancement and Development" also enclosed with this letter. A brief
description of each task is listed below.
Task 1: Water Infrastructure Inventory using Global Positioning Systems or GPS
The field inventory of this project was completed in June. Manhole covers, valves, and
fire hydrants were all located throughout the jurisdiction of Topsail Beach. They were
recorded as point based features with attributes such as type, condition, size, etc using a
GPS receiver capable of 75cm accuracy. This data was then further processed by
connecting each point -based feature, forming the water line infrastructure for the town.
These lines were drawn based on the original engineering diagrams completed in 1969.
Wherever possible the lines were attributed with the appropriate pipe size as drawn on the
original diagrams. This data was ground -checked and amending in October following
hurricane Floyd.. This data resides on the server in the Topsail Beach town hall and is
available for use by anyone connected to the network.
Task 2: Mapping and Cartographic Depiction of Topsail Beach
This task was completed in early September. This cartographic depiction was generated
in map form and printed on 8.5 x 11 paper. These maps were mailed to the town hall.
Map titles or themes were as follows:
=> Location and Vicinity Mapping
=> Historical Hazard / Hurricane Tracking Maps
=> Transportation and Evacuation Route Mapping
=> Storm Surge Inundation plains
=> Flood Zone Mapping using Q3 or DFIRM (where available)
=> Census Block or Demographic Information
=> Home Appraisal Information
=> Special Needs or Sensitive Areas
Task 3: Desktop GIS Training
This training class was provided to employees of the town including administrative
assistants, police officers, and the fire chief. In all, 4 people finished the two-day class
given in October.
Task 4: GIS Database Development
This task was also completed in early September. All available data was collected,
processed and compiled on CD-ROM and mailed to the town hall the aforementioned
maps. These geographic data files were all processed so that the datums, projection
systems, and coordinated systems all matched thus causing each data layer to overlay
precisely the any of the other data layers. These data layers included:
=> Tax Parcels with all Appraisal Information from the County Tax Department
=> SLOSH Hurricane Storm Surge inundation plains
Q3 FEMA delineated flood plains
Beach Access Sites
=> Public Water and Sewer Systems
=> Demographic Information based on Census Tracts
Task 5: GIS Applications Development and Deployment
A software application called GISmo was developed and modified to accommodate
Topsail Beach's data. This application was installed on one of the machines downstairs
in the clerk's office. It was also to be installed on the other machine in the clerk's office
but due to time limitations our staff was unable to finish the installation. The software
was left in the office and is licensed for two copies, so the other copy could be installed
on any machine at any time.
If we can answer any other questions about the completion of these or fulfillment of any
other requirement in the attached scope of services feel free to call us at (919)-759-9214.

Scope of Services
Town of Topsail Beach, North Carolina
Introduction
Topsail Beach has graduated from a rural, sparsely populated region to an increasingly urbanized
region of higher population densities, with a corresponding increase in property values. The influx
of people and the attendant residential and commercial development, often in locations with a
higher risk of severe storm impact, leaves the Town of Topsail Beach ill -prepared for the level of
risk it now faces from repetitive weather related natural hazards, and all associated secondary
hazards.
The use of geographic information tools for hazard mitigation, emergency management, and land
use planning has received overwhelming acceptance by local, state, and federal government
organizations as well as the private sector. This technology is enabling organizations to consider
more effective ways of saving lives, time, and money. Towns, cities, and counties throughout the
world are now embracing GIS for land use planning, emergency services and hazard mitigation.
The task of managing a communities assets and resources is becoming more complex as we witness
escalating growth. It is by no accident that the use of GIS technologies has grown commensurately.
Many local governments have embraced GIS with high expectations. However, after absorbing the
cost of building large databases, only a few organizations have made GIS available to all staff. The
vast majority of local government officials are unable to take advantage of GIS for their daily duties.
Topsail Beach has recognized that GIS has emerged as a powerful and sophisticated means to
manage vast amounts of geographic data. Today, an opportunity exists to utilize GIS for land use
planning, emergency management, and the effective mitigation of natural and manmade hazards.
This project is comprised of data base development, training, GPS data collection, and software
installation, and application deployment. The overriding need of Topsail beach is to develop and
acquire the needed GIS data layers. Data base development is critical to success of land use
planning, hazard mitigation, and emergency management.
General Project Issues:
Project Kick -Off Meeting
The GTG team will establish a time and location for a kick-off meeting. The kick-off meeting will
describe the project approach, the goals and objectives of the project, the technical services
available, the project schedule, and the expected deliverables. The kick-off meeting will enable all
Topsail Beach departments and key staff a chance to understand and comment on the scope of
services.
On -Site Visit and Technical Support
The GTG team will visit each department within Topsail Beach. The GTG team will discuss GIS
technology and offer on -going telephone and technical support for the duration of the project.
GTG will assist Topsail Beach with the purchase, procurement, and installation of all GIS related
hardware and software.
Task 1. Global Positioning System (GPS) - Water Infrastructure
Inventory
Digital mapping has come of age with the union of the Global Positioning System (GPS) and
Geographic Information Systems (GIS). Creating accurate digital maps and associated databases
from real world observations has long been the dream of utility companies, public works directors,
engineers, planners, and anyone who needs up-to-date mapping. GPS mapping/ inventory grade
tools are offering new and exciting ways for collecting accurate, up-to-date digital and attribute data.
The tools for capturing field data need to be fast, flexible, efficient, and easy to use. Today, fast
processing times and flexible data collection technique offers cost effective solutions for creating
accurate and meaningful data. Local governments throughout the world are using mapping or
inventory grade Global Positioning System (GPS) technology (with an accuracy of below one
meter). The GTG,Inc team will utilize the tools afforded by GPS to gather information about the
location, condition, and characteristics of all water infrastructure within the Town limits.

Task 3. Desktop GIS Training
The GTG,Inc team will train up to 9 key Topsail Beach staff on Environmental Systems Research
Institute's (ES" ArcView GIS software. All students will be trained on -site and will receive an
ESRI certification.
Task 4. GIS Database Development
(a) Tax Appraisal Information and Cadastral GIS Data Conversion
The GTG team will organize and develop the conversion procedures and protocols for the
download of all tax appraisal information, and digital cadastral data. The GTG, Inc team will work
closely with the County to export all tax appraisal information and link this data with the most
recent digital parcel description. The GTG team will establish the parameters for allowing Topsail
Beach to receive the most recent and up-to-date data available from the County Tax office.
(b) Developing and Distributing GIS Data on CD
The GTG team will create digital CD data packages of all available GIS data for distribution to each
department in Topsail Beach.. A CD will be developed that will store all relevant and important
digital data for land use planning, emergency management, and hazard mitigation planning. The
GTG team will utilize existing GIS data layers from the NC Center for Geographic Information
and Analysis (CGIA) and NC Division of Coastal Management (DCM), as well as other state and
federal agencies. Specific GIS data layers that may be obtained for this project include:
• SLOSH Hurricane Storm Surge Inundation Areas
• Q3 FIRM data
• DFIRM data
• Average long-term annual erosion rates
• Beach access sites
• Housing variables (including density and home value)
• Public water and sewer systems
• Transportation routes including hurricane evacuation routes
• Demographics (including population, housing and income)
• Political boundaries and census boundaries
• Emergency shelter locations
• Historical hazard events including locations, frequencies and impacts
• Spatially defined high hazard risk areas for flooding and hurricane storm surge
inundation
• Spatially defined shoreline changes including estimated annual erosion/accretion rates
• Frontal sand dune configuration (height, width and distribution)
• Beach characteristics (berm and swash zone width and slope)
• Bathymetry and other nearshore geologic features
• Vegetative distribution including density and type
• Engineered erosion management structures Summaries of state and federal
policies/programs involving hazard mitigation strategies
• Summaries of local policies/ordinances dealing with hazard mitigation
Special attention will be given to the identification of "hazard geo-indicators" - special geologic
features such as historic inlet sites, narrow beaches, overwash fans and aprons, storm surge ebb and
flow channels, inlets and dune gaps that can alter the processes associated with a natural hazard.
Task 5. GIS Applications Development and Deployment
The GTG team will develop, modify, and install a working application of the Map Objects Flood
Mapper Software developed by GTG in 1998. Each community will receive a copy of the Map
Objects Flood Mapper GIS Application. The most up-to-date cadastral and appraisal information
will be used in conjunction with the Flood Mapper Application. The GTG Staff will visit each site
and load and test the application. A short introduction on the use and benefits of the software will
be offered.
Task 3: Desktop GIS Training
This training class was provided to employees of the town including administrative
assistants, police officers, and the fire chief. In all, 4 people finished the two-day class
given in October.
Task 4: GIS Database Development
This task was also completed in early September. All available data was collected,
processed and compiled on CD-ROM and mailed to the town hall the aforementioned
maps. These geographic data files were all processed so that the datums, projection
systems, and coordinated systems all matched thus causing each data layer to overlay
precisely the any of the other data layers. These data layers included:
=> Tax Parcels with all Appraisal Information from the County Tax Department
=:> SLOSH Hurricane Storm Surge inundation plains
=> Q3 FEMA delineated flood plains
=> Beach Access Sites
=> Public Water and Sewer Systems
=> Demographic Information based on Census Tracts
Task 5: GIS Applications Development and Deployment
A software application called GISmo was developed and modified to accommodate
Topsail Beach's data. This application was installed on one of the machines downstairs
in the clerk's office. It was also to be installed on the other machine in the clerk's office
but due to time limitations our staffwas unable to finish the installation. The software
was left in the office and is licensed for two copies, so the other copy could be installed
on any machine at any time.

Dear Mr. Shows:
Geographic
Technologies Group, Inc. You will find in this package a number of maps that depict locational,
demographic, and hazard data for Topsail Beach. You will also find a
CD-ROM that contains a large number of shapefiles for Pender County
and Topsail Beach. This data is in a North Carolina State Plane projection
in a NAD83 datum. The units are in feet. The shapefiles contain
important digital data for land use planning, emergency management, and
hazard mitigation planning.
Also in this package you will find two documents. The first describes the
capabilities and limitations of the Q3 flood data from FEMA. The second
is a data dictionary that describes the shapefiles found on the CD-ROM.
Please call if you have any questions (919) 759-9214.

Q3 FLOOD DATA CAPABILITIES AND LIMITATIONS
DESCRIPTION
Under the National Flood Insurance Program (NFIP), FEMA has created the largest natural
hazard identification data set in the world by mapping flood prone areas throughout the United
States. Currently, FEMA is working to convert these maps to a digital data product. The Q3
Digital Flood Data product, FEMA's first widely available digital flood data, provides
communities with an analytic tool for flood plain management, hazard mitigation planning, public
awareness, and education utilities. Computer based mapping and Geographic Information
Systems (GIS) technology enable users to combine the Q3 Flood Data with other databases to
perform analysis that is difficult or impossible with paper maps. However, the hardcopy FIRM
maps and the Flood Insurance Study remain the legal documents for administering the NFIP and
are the basis of local flood plain ordinances.
CAPABILITIES AND LIMITATIONS
Digital Q3 Flood Data does not replace the existing FIRM hardcopy maps. The product is
designed to support planning activities, some Community Rating System activities, insurance
marketing, and mortgage portfolio reviews. It does not provide base flood elevation information;
thus, it has limited application for engineering analysis, particularly for site design or rating flood
insurance policies for properties located with Special Flood Hazard Areas (SFHAs).
The Q3 Flood Data product can be a valuable tool in screening property addresses to determine
flood risks. However, since the geographic processing performed to develop digital Q3
Flood Data may introduce differences with the FIRM hardcopy sources, users must apply
considerable care and judgement in the application of this product. The digital Q3 Flood
Data cannot be used to determine absolute delineations of flood risk boundaries, but instead
should be seen as portraying zones of uncertainty and possible risks associated with flood
inundation. The Q3 Flood Data should be looked at as a general, rather then a specific guide
at the tax parcel level.
FEMA is currently working on a product known as dfirm 2.01 that will be an improved digital
version of the FIRM hard copy maps.
ZONE AREA ATTRIBUTE DEFINITIONS
ZONE AE: This identifies an area inundated by 100-year flooding, for which base flood
elevations (BFEs) have been determined.
ZONE A: This identifies an area inundated by 100-year flooding, for which no BFEs have
been determined.
ZONE VE: This identifies an area inundated by 100-year flooding with velocity hazard
(wave action); BFEs have been determined.
ZONE X: This identifies an area that is determined to be outside the 100- and 500-year
floodplains.
ZONE X(500) This identifies an area inundated by 500-year flooding; an area inundated by 100-
year flooding with average depths of less than 1 foot or with drainage areas less
then 1 square mile; or an area protected by levees from 100-year flooding.

Hydric soils in Pender County cannot be farmed
under natural conditions without removing woody
vegetation or hydrology manipulation.

The GIS data set is a digital soil survey and is the
most detailed level of soil geographic data
developed by the National Cooperative Soil
Survey. The information was collected by digitizing
maps, by compiling information onto a planimetric
j correct base and digitizing, or by revising digitized
maps using remotely sensed and other information.
Hydric Soils types A (map units that are all hydric
soils or have hydric soils as a major component)
and B (map units with inclusions of hydric sils or
have wet spots) are attributed in this file.
This data was created to assist governmental
agencies and others in making resource
management decisions which rely on the
knowledge of soil conditions.

The National Hurricane Center, in cooperation with
the North Carolina Center for Geographic
Information and Analysis, developed the GIS data
set, Hurricane Storm Surge Inundation Areas
(1993), to reevaluate the extent of the areas
affected by hurricane inundation along the North
Carolina coast. The data depicts the extent of
storm surge inundation areas based on SLOSH
(Sea, Lake and Overland Surges from Hurricanes)
models, for the North Carolina coast. This is the
metadata for the SLOW model (with forward
velocities of less than or equal to 15 mph). Storm
surge is the abnormal rise in water level caused by
wind and pressure forces of a hurricane or tropical
storm. The SLOSH model was developed using
various combinations of hurricane strength (based
on the Saffir-Simpson scale), wind speed, and
direction of movement. Rainfall produced by a
hurricane is not taken into account.

Census block groups are the next to smallest
geographic units for which basic demographics are
available from the Census Bureau.

obtained from the North Carolina Center for
Geographic Information and Analysis.

Following the Office of Management and Budget's
(OMB's) Directive 14, the Census Bureau uses a
set of money income thresholds that vary by family
size and composition to detect who is poor. If a
family's income is less than that family's threshold,
then that family, and every individual in it, is
considered poor. The poverty thresholds do not
vary geographically, but they are updated annually
for inflation with the Consumer Price Index (CPI-U).
-he official poverty definition counts money income
before taxes and excludes capital gains and
noncash benefits (such as public housing,
medicaid, and food stamps).
