The Town of Innisfil's engineering standards provide guidance for the design and construction of municipal infrastructure. First issued in 2011, the engineering standards are regularly updated to remain current as technology and practices change over time. It is the responsibility of consultants to review and apply the latest version of the Town’s Engineering Standards to ensure all design and construction activities comply with current specifications.
