The Texas Coastal Hazards Atlas, Volume 3
Introduction

The Texas Coastal Hazards Atlas - Volume 3, 2003 is being developed in response to the need for technical information by coastal planners and to increase public awareness of coastal processes. The area covered in volume 3 is from Baffin Bay south to the Rio Grande. Following is the database structure.

1.
  Cities
2.
  County Boundaries
3.
  Base Imagery
4.
  Environmental Sensitivity Index (ESI) Shoreline
5.
  Shoreline Change
6.
  Hurricane Surge and Flooding
7.
  1992 National Wetland Inventory (nwi)
8.
  Shorelines
9.
  Washover Features
