A GIS for Dauphin Island

• This outreach program will help to develop a GIS
  tool for future planning- similar in result to
  planting sea oats in the sand to increase the
  chance of survival of the dune

Project Objectives

• Develop a Geographical Information System for the
  Town of Dauphin island
• Identify and create a database of the existing
  infrastructure of Dauphin Island- the Town and
  its environmental matrix
• Integrate the infrastructure database with a
  layered digital map base for analytical and
  management purposes

The Town of Dauphin Island

• Located at the the Mouth of Mobile Bay in Mobile
  County, Alabama
• Is classified as a barrier island situated on the
  Northern Gulf of Mexico

A Brief Historical Perspective

• Was explored in 1699 by Sieur Pierre le Moyne
  dIberville who founded Colonie Louisiane
• Pelican Bay on the south shore of the island the
  French colonists roadstead until 1718 when a
  hurricane closed Pelican Pass trapping 3 ships in
  the harbor
• The island has suffered many devastating
  hurricanes that have drastically altered its
  shoreline- especially the transitory west end.

Expected results

• Create an important planning tool for the Town of
  Dauphin Island, not only for day to day
  management, but also for long range municipal
  planning.
• This system will also help the Town of Dauphin
  Island to recover and to mitigate the adverse
  effects of catastrophic events (e.g, Hurricane
  Katrina).

22
Near Term Schedule

• Meetings with the Town of Dauphin Island are
  scheduled in November 2007 to discuss
  expectations and examine existing mapping
  infrastructure databases.
• Formulate a schedule for implementing upgrades to
  the Towns existing data infrastructure to create
  a workable GIS.
• Seek assistance funding from State Federal
  agencies to help in the cost implementation of
  the GIS
• Work with other agencies to accomplish the goals
  set forth.
