Fire resilient planning for northern communities
This is the first edition of CSA S504, Fire resilient planning for northern communities.
This Standard provides a guideline for planning and design of new fire resilient northern wildland urban interface (WUI) community subdivisions and developments only.
This Standard is complementary to all other standards and codes adopted by local authorities having jurisdiction.
Where contradicting standards occur, the more fire resilient requirement should take precedence, as determined by the appropriate authority having jurisdiction.
CSA Group received funding for the development of this Standard from the Standards Council of Canada, as part of the Northern Infrastructure Standardization Initiative (NISI) with input from the Northern Advisory Committee (NAC).
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This Standard applies to the external vulnerabilities of structures to wildfire within the interface zone areas in northern communities.
Note: This Standard can be utilized by communities outside of the northern regions specified (i.e., areas where communities fall within forested areas).
This Standard specifies requirements for fire resilient community planning, building design, materials for new developments, and also for re-locatable industrial, commercial, or residential structures in northern regions.
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.
