Large grocery stores in Chicago soon will be able to start selling liquor three hours earlier on Sundays, a move supporters say will help Chicago businesses compete with nearby suburbs.

The City Council today adopted without debate a plan to allow liquor sales to start in large stores at 8 a.m., one of a dozen or so key measures on a jam-packed agenda that will shape how Chicagoans live. The meeting can be watched live at the City Clerk's web site.

Ald. Patrick O'Connor's ordinance applies to stores larger than 10,000 square feet with no more than 25 percent of their shelf space dedicated to liquor sales.

The 40th Ward alderman, who is Mayor Rahm Emanuel's floor leader, scaled back his idea of allowing all liquor sales at 8 a.m. Sundays after several aldermen opposed that version on the grounds that they didn't want loitering outside liquor stores or for alcoholics to get their hands on booze earlier in the day.

The Sunday 11 a.m. start to alcohol sales has been in place for "many, many decades" in Chicago, city Liquor Commissioner Gregory Steadman told aldermen earlier this year, in part because religious groups wanted to keep Sunday morning as a time for worship.

O'Connor first began exploring a change to the start time after talking to grocery store owners about moving into empty Dominick's stores. The new version of the ordinance does not allow larger liquor retailers like Binny's Beverage Depot to sell earlier on Sundays, but O'Connor said it's possible the ordinance could be changed down the road if the more conservative version passes the council and there aren't any problems.

Aldermen also approved a plastic bag ban that will require Chicago shoppers to change the way they tote groceries, clothing and other items from store to home. The ban would first go into effect in August 2015 and only apply to chain stores — defined as a group of three or more that have the same owner — or franchise stores of more than 10,000 square feet. Smaller chain stores and franchises would have to ditch the plastic bags a year later.

Aldermen also are scheduled to consider rules for pedicab drivers, the tricycle taxis with passenger seats popular in night life and tourist districts of the city

Under the proposed regulations, they would be banned from the Loop during rush hour and outlawed entirely on State Street and Michigan Avenue between Congress Parkway and Oak Street, bread-and-butter stretches for operators. The ordinance would also require licenses for pedicabs and set a cap on the number issued at 200.

The pedicab measure comes before the City Council as aldermen also are scheduled to consider cracking down on online ride-sharing services, another currently unregulated competitor to the traditional taxi industry.

Under the ordinance, companies whose driver workforce averages more than 20 hours per person each week would face stronger oversight, including a requirement that all their drivers obtain chauffeur’s licenses.

But the proposed ordinance targeting companies such as Uber X, Lyft and SideCar leaves it to the ride-share companies to police drivers in terms of how many work hours are logged.

The revisions also give the city authority to cap “surge pricing” when there is peak demand, such as during rush hours. Under surge-pricing conditions, fares can increase as much as tenfold.

The companies said that while they prefer a free-market approach, they support the mayor’s revised ordinance.

Aldermen also are expected to vote on a proposal to allow large grocery stores to start selling liquor at 8 a.m. on Sundays instead of the current 11 a.m. The idea of Ald. Pat O'Connor's ordinance is to help city supermarkets compete with suburban stores.

In addition to those high-profile measures, the City Council will take up several other issues:

*A crackdown on illegal valet parking operations.

*Impose larger fines for those who evade city stickers by registering their vehicles outside city limits but keep them in Chicago.

*Approve higher fines for tow truck drivers who tow multiple cars a short distance from where they are illegally parked before going back to take each car to the tow company lot. The practice, known as staging, already is against the law, but the proposal would allow police to issue tickets of between $500 and $1,000 against tow truck drivers rather than just reporting the practice to state licensing officials.

*Aldermen voted to sign off on a $5 million legal settlement for a man who lost his leg after being hit by a car that skidded on ice caused by a leaky water main.

*End free Sunday parking in some areas.

*Require those who unlock cell phones to take down identification information. The idea is to make it tougher on cell phone thieves to profit.

*Allow small digital advertising signs to start up again after a nine-month moratorium, with some restrictions.

*Outlaw new petcoke storage terminals while requiring three existing operations along the Calumet River to file quarterly reports on the amount of petroleum coke and coal shipped through Chicago. The Emanuel administration scuttled a proposal that would have allowed factories to store and burn the refinery byproduct anywhere in the city.

After the council meeting, Mayor Rahm Emanuel is scheduled to take reporters' questions for the first time since the Tribune reported Friday that some scenes of CNN's documentary series "Chicagoland" were coordinated by City Hall and the show's producers.

The mayor's office announced late Tuesday that it would propose a measure to add six more food truck locations. The sites to be considered: 437 S. Columbus Drive, 200 S. LaSalle St., 151 N. Franklin St., 185 N. Upper Columbus Drive, 105 E. Monroe St. and 300 S. Wabash Ave.
