A City Council effort to lower speed limits to 20 miles per hour on residential streets citywide has been dropped in favor of a bill that would set limits at 25 mph on narrow one-way streets.

The original bill, sponsored by Council Member David Greenfield, would have set speed limits no higher than 20 mph “on all streets fewer than sixty feet wide in areas zoned for residential purposes.” But DOT told the council in October that state law permits the city to set speeds at 15 to 24 miles per hour only if other physical traffic-calming treatments are also implemented, or if a street is within a quarter-mile of a school.

To set speed limits at 20 mph citywide, DOT suggested lobbying Albany to change the state law before passing a local law.

When WNYC produced a map indicating that most city streets are close enough to a school to be eligible for a 20 mph limit (though only during school hours), council transportation chair James Vacca said he would “push legislation in the council to limit speeds in those areas.” Then last week, Vacca told WNYC the council was “aiming for 25 miles per hour on narrow, one-way streets.” Greenfield told the Times yesterday that the revised bill would set speed limits at 25 mph on one-way streets with one lane of traffic.

Speaker Christine Quinn says council members want to pass the bill before the year is out. We have a call in with Greenfield about the revisions and will have a full report next week.
