1. Sources: Interstates, Non-Interstate Principal Arterials, Minor Arterials, and NHS - National Highway Planning Network (NHPN). Rails - Federal Railroad Administration.
Ports - Digitized from Digital Orthophoto Quadrangles clipped to the mean high water line. Airport Property and Runways - Tele Atlas.
2. The NHPN includes all Interstates and other Principal Arterials, all Rural Minor Arterials, and a small portion of the Urban Minor Arterials, as well as the NHS.
3. This study includes the Rural Minor Arterials but not the Urban Minor Arterials.
4. See section 3 of the "Study Goals and Methodologies" for an explanation of how these results were generated.
The results should not be understood as defining specific changes in water levels at precise points in time.
5. The Total column for each scenario includes the sum of Regular Inundation and At-Risk. The At-Risk column does not include Regularly Inundated data.
