Impact Levels
Coastal Flooding - Potential Impact Descriptions
Extreme
Potential for Extreme Impact: Aggressive preparations should be made for the threat of catastrophic coastal flood damage from sea water. If realized, expect widespread deep inundation within the flood zone, possibly reaching several miles inland. Extreme beach erosion with several new inland cuts. Many large sections of near-shore roads washed out and/or low-lying escape routes severely flooded. A powerful and scouring storm surge and tide greatly accentuated by intense battering wind waves breaching dunes and possibly seawalls in widespread locations resulting in structural damage to shoreline buildings, with several washing into the sea. Damage greatly compounded from considerable floating debris. Extensive damage to marinas, docks, and piers. Numerous small craft broken away from moorings, lifted onshore and stranded. Descriptions are consistent with damage caused by coastal flooding 7 feet or more in depth (above ground level) in hardest hit places.
High
Potential for High Impact: Aggressive preparations should be made for the threat of major coastal flood damage from sea water. If realized, expect large areas of deep inundation within the flood zone. Severe beach erosion. Several sections of near-shore roads washed out and/or low-lying escape routes severely flooded. A powerful and scouring storm surge and tide accentuated by battering wind waves breaching dunes and possibly seawalls in scattered locations resulting in structural damage to shoreline buildings, with a few washing into the sea. Damage compounded by floating debris. Moderate to major damage to marinas, docks, and piers. Many small craft broken away from moorings, especially in unprotected anchorages, lifted onshore and stranded. Descriptions are consistent with damage caused by coastal flooding of 5 to 7 feet in depth (above ground level) in hardest hit places.
Moderate
Potential for Moderate Impact: Preparations should be made for the threat of moderate coastal flood damage from sea water. If realized, expect partial inundation within the flood zone. Major beach erosion. A few sections of near-shore escape roads weakened or washed out, especially in historically vulnerable low spots. Storm surge and tide accentuated by wind waves breaching dunes and possibly seawalls in scattered locations to result in damage to shoreline buildings, mainly in historically vulnerable spots. Moderate damage to marinas, docks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages. Descriptions are consistent with damage caused by coastal flooding of 3 to 5 feet in depth (above ground level) in hardest hit places. 
Low
Potential for Low but Concerning Impact: Preparations should be made for the threat of minor to locally moderate coastal flood damage from sea water. If realized, expect partial inundation within the flood zone, especially for low-lying areas. Moderate to locally major beach erosion. Very heavy surf breaching dunes in isolated locations, mainly in historically vulnerable spots. Descriptions are consistent with damage caused by coastal flooding of 1 to 3 feet in depth (above ground level) in hardest hit places. 
None
Potential for Little to No Impact: Preparations are not needed as appreciable damage is unlikely. However, rough surf conditions, minor beach erosion, nominal sea water encroachment, and stronger than normal rip currents may still occur.
