Zone A estimated Flood Zone
Larry Reiter, Planning
Director, Lumpkin County estimates the 100 year flood elevation 1300 - 1302'
which is he states, about 16' of flood water above the ground surface of Hurricane Creek Wildlife Preserve land elevations of 1284' - 1288'.
This result was
obtained from his FEMA flood maps of Lumpkin County,
which were updated in 2008, which exist as a GIS overlay in the Lumpkin Planning
Office. These maps are accessible to
the public,
and Mr. Reiter demonstrated these results and produced this overlay
for us on request.
Therefore, the 100 yr. flood WILL BE devastating to the ponds/wetlands
at Hurricane Creek as we have previously stated. Although data of more
frequent floods is not readily available, we have eyewitness evidence
that the flooding in 1996, which is estimated to be the 10-20 year flood, will produce levels about 5' of water above
the Hurricane Creek and surface.
For the layman, the 10 yr. flood is one that happens about every 10
years. Likewise, the 100 happens on average once in a 100 yr.
But we have
to consider that these floods do happen more
frequently than predicted,
due to La Nina / El Nino climate fluctuations regionally and nationwide, and what development of the land that is
happening upstream. Likewise, if Hurricane Creek. is partially
timber harvested as planned and soils disrupted by heavy machinery, this
would likely affect and accentuate flooding downstream, at the Hwy. 52 bridge,
at Pine Valley on Hwy. 9, etc.
If instead, the historic farm was planted with trees that would
likely reduce flooding downstream.
