Mayor Rick Gray’s administration wants to streamline the city’s method of sweeping streets and ticketing motorists who do not move their cars for the posted sweeping times.

Gray said Monday the city is considering adding digital cameras to its sweepers.

Sweeper drivers would snap pictures of license plates on illegally parked cars, and tickets would be issued later, the mayor said. Those images would include the date and time.

The camera would allow the city to do away with the sweeper escort. The escort, working with the sweeper, writes tickets for cars left parked along the posted streets.

“The ticketing of vehicles slows the whole street-sweeping process down,” said Gray.

The mayor said City Hall staff members are also considering reducing the posted times for sweeping. That window of three to four hours could be cut in half, he said.

That change would reduce the inconvenience to residents who park their cars on the street in front of their homes, he said. The move would also incur the cost of changing all the street-sweeping signs.

Gray raised the issue at a City Council meeting last month. He said the city is looking at stricter enforcement of street-sweeping times. Some residents return their cars to the streets immediately after the sweeper passes — even if the posted time has not elapsed. That prevents a second sweeping, the mayor said.

Residents have complained that stricter enforcement is not necessary, saying they believe the city has had an unwritten rule that residents may move their cars back to the street after the sweeper has gone through.

“There is no new policy in effect right now,” Gray said, but he added that a change may come later in the spring. “There will be plenty of notice,’’ he said.
