Draft Scope/Description:

1.1 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.

1.2 Exclusions

This Standard does not apply to coastal and marine infrastructure for which direct exposure to the water is necessary to meet operational requirements (e.g., breakwaters, revetments, sea dikes, jetties, wharves, piers, quay walls, and other marine facilities).

1.3 Users

This Standard is intended for use by

a)    designers of buildings and infrastructure potentially exposed to coastal flood hazards;

b)    professionals involved in design for retrofitting of buildings and infrastructure for coastal flood resilience;

c)    authorities responsible for coastal flood resilience measures for buildings and infrastructure;

d)    owners and operators of buildings and infrastructure;

e)    educators for the purpose of knowledge transfer;

f)     community planners; and

g)    others with a vested interest in understanding or managing coastal flood hazards and risks to buildings and infrastructure.

1.4 Applicability

This Standard applies to flood risk assessments in coastal areas, including Canada’s marine coasts and the Great Lakes. This Standard might also be useful for informing flood risk assessments on the shores of other large lakes in Canada.

1.5 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
