community was noted. Potential evacuation and connection routes were examined for low
spots (i.e., those areas likely to be inundated during a flood event) and stream or water body

For example, Grand Bank is a small coastal town (Pop. 2415) located on the Burin Peninsula

streams. There does not appear to be any evacuation options leading to higher ground.
