Evacuation Maps Are Changed for 2010

In response to better data in some key computer models, more than 73,000 of Pinellas County’s 316,425 parcels are changing evacuation levels for the 2010 Atlantic hurricane season.  Of the parcels that changed levels, 18,861 were placed in a higher surge category (e.g., level B to level C) and 54,332 were moved to a lower surge category (e.g., level D to level C). 

These changes are due to three important factors:

·         Pinellas County has received new light detection and ranging (LIDAR) data giving more accurate information on ground elevations above sea level.

·         The National Hurricane Center is using a more powerful Sea Lake Overland Surge from Hurricanes (SLOSH) computer model to better simulate anticipated surge levels.

·         Unusual and destructive storms which brought very high storm surges, such as Ike (2008) and Katrina (2005), were considered in the model process.

The evacuation zones are also using a new color scheme this year. 

The new colors have been selected to create a statewide standardized color scale.  The new scale is:

o    Level A – Red

o    Level B – Orange

o    Level C – Yellow

o    Level D – Green

o    Level E – Purple

It is important to note that evacuation maps are not the same as flood zone maps used to determine a property’s insurance rates. Flood zones can be viewed at the National Flood Insurance Program.  

Residents are encouraged to verify their evacuation levels before June 1. The new data can be found at Pinellas County Emergency Management and clicking the Know Your Zone tab or by calling (727) 453-3150 and entering the home’s ten-digit land line phone number.  This service does not work for cell phones.  The information will also be available on Pinellas County Utility bills and the Truth in Millage notice sent by the Property Appraiser’s office in August.
