West-3, West-4, and Central-3
These three Sub-regions of mainly coastal communities are adjacent to each other along the
southern coast of the Western Region. Due to the low Growth Priority Factors and the relatively
low Flood Damages Estimates Priority Factor, additional strategies are not recommended
beyond those appropriate for all Sub-regions.
Central-1 and Central-2
This Sub-region, based on its relatively high population density and high density of communities
would benefit from a flood forecasting and warning system. As this region receives much of its
overland flow from Sub-region Central-2, such an early warning system could be established
across both sets of Sub-regions to minimize flooding impacts to downstream areas.
In addition, communities in Central-2 have the highest Flood Damages Estimates Priority Factor
of any Sub-region. Therefore, these Central-2 communities also have the third highest Growth
Priority Factor of all Sub-regions and should consider adding four additional strategies to their
Plan:
Development and re-development policies,
Promotion of flood insurance to landowners,
A formal process to identify and evaluate properties for which acquisition has a strong
potential to reduce flood losses in the future, and
Structural flood mitigation strategies to reduce flood impacts on those communities and
portions of communities with the greatest flood vulnerabilities.
East-1
Despite the relatively high density of communities in this Sub-region, population in each
community is low. This is likely the reason for the relatively low Flood Damages Estimates
Priority Factor. Therefore, no additional Non-Structural strategies are recommended for East-1.
However, due to the Sub-region‟s location on the eastern side of the island, with its higher
vulnerability to expected sea level rise and hurricanes/tropical storms, local communities should
add strategies in their flood mitigation and adaption program to identify locations for structural
flood protection measures.
East-2
East-2 communities have a relatively high population within each community. Therefore, with
relatively significant existing infrastructure and high population densities along the coast, these
