Figure 7.1 – Maps depicting coastal areas shoreline sensitivity to sea level rise and flood risk in a) Greater Victoria,
b) Nanaimo and c) Courtenay/ Comox. Degrees of sensitivity marked by red, amber, yellow, green and black in order
from most to least sensitive. Areas that are projected to be vulnerable to coastal flooding by 2100 are shaded in
blue. The 2100 coastal floodplain area dataset uses sea level rise and approximate flood construction levels (FCLs).
It includes a nominal allowance for wave effects but does not account for river flooding effects nor a combination
of these effects with sea level rise, the presence or absence of flood protection structures, and has not been ground
truthed. Data are from the Province of BC and Kerr Wood Leidal.
