6. Task F – Identify Flood Vulnerability Mitigation and Adaptation Strategies
There are 529 communities identified in Newfoundland and Labrador, each designated with a
Local Government Profile number. A list of these communities is included as Appendix A -
Prioritization of Communities for New Flood Plain Mapping of this report. This list of
communities is sorted based on the determined prioritization for updates to the communities
existing flood plain maps. In addition to flood plain mapping updates, there is a suite of flood
mitigation measures that Provincial government officials and the decision makers should
consider for adoption to most effectively serve and protect population, property, and
infrastructure. It is recommended that every community across the Province, including those not
designated as a high priority for map updates, implement an active process, at a level
appropriate to their issues and needs, to develop, renew and update local flood mitigation
mechanisms, as a result of land use, watershed conditions, and climate change effects. The
goal of these mitigation and adaptation strategies is to reduce the risk to life and property from
current flooding vulnerabilities, as well as those projected to occur.
Communities throughout Newfoundland were grouped based on their generally common
physiographic characteristics, and then each group‟s general flood vulnerability was evaluated,
based upon watershed characteristics, climate change factors, and socio-economic factors, to
make recommendations of applicable potential flood mitigation strategies for each grouping.
The Provincial government, along with individual communities, should evaluate the applicability
of each of the strategies recommended for each grouping, followed by an assessment of
implementation costs and associated benefits to the community. The strategies suggested in
this section could be then used as the basis for a community‟s overall Flood Mitigation &
Adaptation Program.
Communities in Labrador have not been included in this identification of flood mitigation and
adaptation strategies. This is because there have been few reported instances of property
damage due to flooding in Labrador. This does not preclude application of the general flood
mitigation and adaptation themes discussed in this section.
Please note for Task F the names used for communities and areas are a combination of those
that were in place when the FRM studies were done in the 1980s and 1990s and those reflected
by the new LGP numbers due to a need to use data from both old FRM studies and the LGP
list.
6.1 Community Analysis
To identify appropriate flood mitigation and adaptation strategies to include in a Flood Mitigation
& Adaptation Program, communities must first identify flood vulnerabilities. Upon studying the
