Forget about driving your favorite baseball fan to the gates of PNC Park on All-Star Game day, unloading a huge sign touting a favorite player, then parking nearby and selling knock-off T-shirts out of your trunk. Under proposed temporary regulations put forth by Pittsburgh Mayor Bob O'Connor's office yesterday, none of that could happen.

The mayor yesterday gave City Council a nine-page list of temporary rules that would, if adopted, govern traffic, security, vending and signs around PNC Park and the David L. Lawrence Convention Center from July 6 through the morning of July 12. The legislation indicates that security would feature police canine units, X-ray-like scans of vehicles and strict policing of peddlers.

The rules follow "the model that's been used by Major League Baseball in past years," said mayoral spokesman Dick Skrinjar. "It's a temporary provision that changes some of the normal, everyday routines that we have."

He said the city expects disruption similar to any large event, but spread over six days.

Crafted in consultation with federal, state and county officials, the temporary rules would restrict driving within a "safety zone" around the two facilities in which events will be held.

The zone would stretch from Art Rooney Way to the Andy Warhol Bridge on the North Shore. It would include the Roberto Clemente and Warhol bridges and parts of Fort Duquesne Boulevard, the 10th Street Bypass, Sixth, Seventh and 10th streets, Downtown.

Streets would be closed or restricted at times, depending on the location of events. Any vehicle seeking to enter the zone could be subject to search using scanning devices and dogs.

The rules are similar to those used by Houston, host of the 2004 All-Star Game, said Frank Michel, spokesman for that city's Mayor Bill White. The city limited parking and driving and ran shuttle buses from various compass points to its Downtown ballpark, leaving traffic "relatively unscathed," he said.

Houston got $4.2 million from the state of Texas to help cover costs.

Mr. Skrinjar said the city hasn't calculated the expected cost of additional public works and police manpower, and does not know whether federal or state funds would cover expenses. He noted that Department of Homeland Security money has paid for some new equipment.

The rules would bar pedestrians from carrying poles, pipes, wooden posts longer than 12 inches or pointed posts of any size into the safety zone. On July 11, game day, they would not be allowed to carry wooden, metal or plastic signs larger than 18 inches across.

The American Civil Liberties Union is concerned about how the rules will affect rights to protest but doesn't yet have enough detail to say whether they would create "sterilized non-protest zones," said its state legal director, Witold Walczak.

North Side neighborhood group leaders said they have not yet been consulted on the rules. "Certainly, we're supportive of strong security measures for the event, as long as it balances the needs of residences and businesses," said Mark Fatla, executive director of the North Side Leadership Conference.

Businesses within the safety zone could keep operating and would consult with the city on means of getting employees and goods in and out.

Vendors would be subject to rules about where and when they could sell. Laws against illegal knock-off merchandise would be "strictly enforced," according to the legislation.

Rules governing signs would be loosened. As many as 1,200 banners related to All-Star Game activities or baseball would be allowed citywide, and up to one-third of each sign could contain sponsor logos or ads.

The Public Works Department would approve sign locations and charge $10 per banner.

If the game is rained out and has to be played a day late, the rules would extend through the morning of July 13. Council is set to debate the proposed rules June 7, with a final vote likely June 13.
