The Miami Herald wrote about FEMA's new maps today so I decided to look up the nuke plant. Looking at the FEMA flood map of Turkey Point you can see just how vulnerable our nuclear power plant is to storms (hit on image to enlarge it).
FEMA on flood zones and a FEMA flood map of Coconut Grove for comparison: (Unfortunately Fema does not do a good job of defining its zones....) Just know that all of Turkey Point is in a HIGH RISK AREA not only for flooding. Part of it is subject to storm waves.
Zone A: Areas subject to inundation by the 1-percent-annual-chance flood event generally determined using approximate methodologies. Because detailed hydraulic analyses have not been performed, no Base Flood Elevations (BFEs) or flood depths are shown. Mandatory flood insurance purchase requirements and floodplain management standards apply.
Zone AE: Areas subject to inundation by the 1-percent-annual chance flood event determined by detailed methods. Base Flood Elevations (BFEs) are shown. Mandatory flood insurance purchase requirements and floodplain management standards apply.
Zone AH: Areas subject to inundation by 1-percent-annual-chance shallow flooding (usually areas of ponding) where average depths are between one and three feet. Base Flood Elevations (BFEs) derived from detailed hydraulic analyses are shown in this zone. Mandatory flood insurance purchase requirements and floodplain management standards apply.
Zone V: Areas along coasts subject to inundation by the 1-percent-annual-chance flood event with additional hazards associated with storm-induced waves. Because detailed hydraulic analyses have not been performed, no Base Flood Elevations (BFEs) or flood depths are shown. Mandatory flood insurance purchase requirements and floodplain management standards apply.
* VE Zones, also known as the coastal high hazard areas. They are areas subject to high velocity water including waves; they are defined by the 1% annual chance (base) flood limits (also known as the 100-year flood) and wave effects 3 feet or greater. The hazard zone is mapped with base flood elevations (BFEs) that reflect the combined influence of stillwater flood elevations, primary frontal dunes, and wave effects 3 feet or greater.
* AE Zones, also within the 100-year flood limits, are defined with BFEs that reflect the
combined influence of stillwater flood elevations and wave effects less than 3 feet. The AE Zone generally extends from the landward VE zone limit to the limits of the 100-year flood from coastal sources, or until it reaches the confluence with riverine flood sources. The AE Zones also depict the SFHA due to riverine flood sources, but instead of being subdivided into separate zones of differing BFEs with possible wave effects added, they represent the flood profile determined by hydrologic and hydraulic investigations and have no wave effects.
* AO Zones, representing coastal hazard areas that are mapped with flood depths instead of base flood elevations. Depths are mapped from 1 to 3 feet, in whole-foot increments. These SFHAs generally are located in areas of sheet flow and runoff from coastal flooding where a BFE cannot be established. The AO Zone is also used in riverine flood mapping.
* AH Zones, representing coastal hazard areas associated with shallow flow or ponding,
with water depths of 1 to 3 feet. These areas are usually not subdivided, and BFEs are mapped.

Makes you feel like getting out of South Florida.
I guess David had no answer for this post (see comment in next post)
