This is the first edition of CSA Z663, Land use planning in the vicinity of pipeline systems. It supersedes and replaces CSA PLUS 663, Land use planning for pipelines: A guideline for local authorities, developers, and pipeline operators published in 2004. This Standard aims to address the challenges facing land use planning near pipelines in Canada; outlining key elements that when consistently applied will enhance safe and informed development. Users of this Standard are reminded that additional and site-specific requirements might be specified by federal, provincial/territorial, or municipal authorities. While risk-informed decision-making has become one of the methods supporting informed land development, it is not addressed in this Standard; however, users may choose to use risk-informed decision-making practice. The Technical Committee chose not to incorporate risk-informed decision-making given the multitude of other standards that more aptly address those practices.
