5. A hurricane making landfall on the island would produce the very highest water levels in
Newfoundland. A coarse preliminary attempt at quantifying the cumulative factors was
presented for illustration purposes only. Numerous other factors, unique to each storm
and its particular behavior, as well as the local topography would affect that high water
mark both downward as well as upward. As a result, a range of recommendations to
mitigate damages should be considered. Firstly, since a 1 in 50 year event could occur
in a year or two from now, local emergency plans should be reviewed to ensure they
include the potential impacts of a Hurricane. Additional measures may also be required
to ensure public safety such as evacuation routes etc. Secondly, a closer study of
Hurricanes is recommended to determine a range of likely tracks and intensities with a
view to better assessing the likely wind directions and storm surges which specific
communities may have to deal with. Such a greater understanding of the Hurricane
threat to the island may then allow a close assessment of the impacts of such
hypothetical storms in specific communities given their unique topography. Finally, flood
plain maps for these vulnerable communities could be updated and other defenses
considered.
