A summary of significant Los Angeles City Hall decisions affecting the Westside in the past week. : CITY COUNCIL

* AIR POLLUTION: Councilman Michael Woo has introduced a proposal seeking the establishment of a city smog-reduction program that would use the latest technology to detect vehicles generating high amounts of pollution and require them to be fixed. The method could reduce air pollution by 30% to 40% and forestall the need to impose harsher regulatory programs on the public, Woo said.

* STREET CLOSURE: Approved the temporary closure of 63rd Street from Mosely Avenue to Damask Avenue in Ladera Heights from 1 to 6 p.m. July 19 for a block party by the area’s Neighborhood Watch group. The group is celebrating its 10th anniversary.
