0.1 Inclusions
This Standard applies to coastal flood risk assessments for communities, buildings, and infrastructure in Canada. The outcomes of such assessments are intended to inform the design of new buildings and infrastructure, and retrofitting measures for existing buildings and infrastructure. 
The Standard identifies
a)    a framework for conducting coastal flood hazard and risk assessments; 
b)    data requirements;
c)    key concepts and terminology; 
d)    levels of analysis and the circumstances in which they should be applied;
e)    recommendations for effective engagement;
f)    recommendations for establishing risk-based design criteria;
g)    methodologies for assessing coastal flood hazards and risk; and
h)    risk management, mitigation, and adaptation.
0.2 Exclusions
This Standard does not apply to coastal and marine infrastructure for which direct exposure to the water is a functional requirement (e.g., breakwaters, revetments, sea dikes, jetties, wharves, piers, quay walls, and other marine facilities).

Project Need
More than 15 million people live within 20 km of Canada’s marine and Great Lakes coasts. The buildings and infrastructure that they rely on are vulnerable to coastal flood hazards resulting from extreme water levels, waves, tsunamis and other contributing factors. The risks associated with coastal flood hazards are escalating over time due in part to development and population growth in coastal zones and climate-driven effects, such as global sea-level rise. These growing concerns are prompting a broad re-think of how coastal flood risks can be better managed in Canada, including how building and infrastructure design practice can be enhanced to support resilience objectives.

Note: The information provided above was obtained by the Standards Council of Canada (SCC) and is provided as part of a centralized, transparent notification system for new standards development. The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.

Individual SDOs are responsible for the content and accuracy of the information presented here. The text is presented in the language in which it was provided to SCC.
