City leaders are increasingly having less patience with trash in yards, which means residents may soon have less time to pick it up.

Lawrence city commissioners at their meeting Tuesday evening will consider new regulations designed to shorten the amount of time to pick up pizza boxes, beer bottles and other types of litter that often are found in some neighborhoods across the city.

“The current regulations are totally ineffective,” said Candice Davis, a member of the Oread Neighborhood Association, which asked commissioners to consider tightening its standards.

Commissioners at their weekly meeting will consider new regulations that they hope will cut the process of citing people for trash problems by up to a week. Currently, city code allows people up to 15 days to clean up the trash, before facing a fine. The proposed regulation drops that down to seven days.

But Brian Jimenez, the city’s code enforcement manager, hopes other changes to the regulations make it more likely that the trash will be picked up much quicker than the seven days. Currently, the city is required to send notices of violation by certified mail. Jimenez said that can take several days, because the certified mail process requires a signature.

The proposed regulations will allow the city to place a notice of violation on the front door of a property, in addition to sending a letter. Jimenez hopes the new on-site notification will prompt people to act quickly.

“Hopefully, people will see that and recognize that there’s a problem they need to address right away,” Jimenez said.

The city investigates about 400 complaints per year related to the city’s environmental code, which deals with trash and other matters related to trash and the exterior appearance of properties.

Commissioners meet at 6:35 p.m. Tuesday at City Hall, Sixth and Massachusetts streets.
