Patios made permanent
The Elgin Street sidewalk patios that were created as part of a pilot project
are here to stay. Patios south of MacLaren Street, where pedestrian levels are
lower, must leave 1.8 metres of clear sidewalk, while patios north of MacLaren,
are required to leave two metres of clearance because of the greater number of
pedestrians. via
