Mayor Michael Bloomberg's congestion pricing plan was on the agenda Thursday at a Riverdale meeting hosted by Assemblyman Jeffrey Dinowitz.

Dinowitz hosted the forum at the Riverdale Jewish Community Council. The assemblyman said congestion pricing may have adverse effects, such as drivers jamming local neighborhoods in an effort to avoid the tolls.

The lawmaker also said he's worried about air quality lessening in those neighborhoods, possibly driving up childhood asthma rates.Dinowitz said while the goal of congestion pricing is to encourage people to use mass transit, he believes some subway lines are already operating at full capacity.

Assemblyman Richard Brodsky was also on hand to speak against the proposal. Partnership for New York City CEO/President Kathryn Wylde spoke in favor of the plan.

Community members got a chance to speak their mind at the public forum.

Bloomberg wants drivers entering Manhattan below 86th Street to pay $8 Monday through Friday from 6 a.m. to 6 p.m. Truck drivers would pay $21.
