On November 8, 20 15, the City of Atlantic Beach experienced a s ign ificant amount of
rainfall within a short period oftime. This rainfall resulted in the flooding on Aquatic
Drive, Skate Road, Cavalla, as well as other areas of the City. Numerous homes in these
a reas were damaged as a result of water intrusion. The areas impacted by the flooding
arc all within a low lying flood zone. However, there were other co nditions that also
contributed to this event. At our request, representatives from the National Oceanic and
Atmospheric Admini s tration (NOAA) investigated these conditions and presented their
findings to City Staff on November 13 , 2016. It was recommended that the
representatives from NOAA g ive the same presentation to the City Commission for their
information only.
BUDGET: N/A
RECOMMENDATIONS: Provide presentation to the C ity Commission on February 8,
2 0 16.
