Physical Impacts<br />
The District’s extensive and irregular coastline, and numerous populated islands, causes high<br />
exposure to sea level rise and storm surge. Dissemination areas with the greatest number of<br />
residences that could be inundated include dissemination areas 114, 116, 117 and 118; those<br />
with the most residences at risk of isolation include dissemination areas 113, 114, 115, 117 and<br />
118.<br />
Sea level rise alone may require a choice between costly improvements to infrastructure such as<br />
bridges and roads, or the abandonment of certain infrastructure components. Because sea level<br />
rise is an incremental process, the District has the opportunity to engage in long term planning in<br />
anticipation of its impacts.<br />
Storm surge, however, is much less predictable – a very severe storm could occur imminently,<br />
or not for many years. While a storm surge would be relatively short in duration, damage to and<br />
debris on roads and bridges could cause more lasting disruption to access, leaving emergency<br />
services and vehicles bearing essentials such as home heating oil, unable to reach residents;<br />
and residents unable to seek outside help or obtain supplies. Damage to power lines resulting in<br />
loss of electrical power is another potential impact; this is of particular concern during winter<br />
months when many residents would be without home heating. The loss of refrigerated and<br />
frozen food would also be a significant hardship for residents with limited financial resources.<br />
The cost of repairs to damaged infrastructure could be a substantial burden for the Municipality.<br />
<strong>Social</strong> <strong>Vulnerability</strong> on the Coast<br />
Overall social vulnerability in the District tends to be near or below average for Nova Scotia. The<br />
highest social vulnerability amongst coastal dissemination areas occurs in dissemination area<br />
117, which also faces a high risk of impacts from sea level rise and storm surge. However, this<br />
area is also recognized for a high degree of community involvement and cohesiveness that can<br />
help it to overcome these challenges and meet the needs of socially vulnerable residents.<br />
While the remaining dissemination areas have overall social vulnerability that is at or below<br />
average for Nova Scotia, the scores for individual indicators provide useful information about<br />
each area’s strengths and weaknesses.<br />
Indicator scores for low income, unemployment, and reliance on government transfer payments<br />
vary widely amongst coastal dissemination areas, and all three conditions may not be present in<br />
a single dissemination area. However, any one of these conditions may limit the ability of some<br />
coastal residents to invest in measures to prepare for, withstand, and recover from a natural<br />
hazard.<br />
The District has a large population of seniors, particularly in dissemination areas along the coast.<br />
Some of these residents may have a limited ability to understand or act upon warnings about<br />
extreme weather events, and are more likely than other residents to require assistance with<br />
evacuation in advance of, withstanding, and recovering from a natural hazard. Those living alone<br />
– who are also concentrated in coastal areas – are at particular risk in the event of extreme<br />
weather.<br />
Throughout the District, low levels of education are common. While education rates are higher in<br />
many coastal dissemination areas, low education is still a concern in others. While many<br />
residents without secondary education have good common-sense knowledge and experience of<br />
local weather patterns, some may also have greater difficulty understanding scientific<br />
information about natural hazard impacts, or warnings and evacuation orders, particularly if they<br />
have limited literacy.<br />
