The city is cracking down on large trucks and trailers parked on the street overnight.

The Board of Alderman has changed an ordinance that, in essence, will now prohibit the parking of all trucks with trailers, box trucks and other large trucks on city streets overnight. Already prohibited in the ordinance is the on-street parking of motor homes, boat trailers, camping trailers and the like.

“It’s still OK to park a pickup truck or a regular van on the street overnight,” said Alderman Phil Vetro, who’s also the owner of a construction company. “Otherwise, I wouldn’t be able to park my own pickup truck in front of my house.”

Officials say that prohibited will be all vehicles that are more than 21 feet long and/or 8 feet tall, minus the radio antenna. There are other stipulations, too — the gross vehicle weight can’t exceed five tons and there can’t be more than one rear axle.

Alderman Bryan Anderson said that the issue came up a few months back when he was looking into a complaint from one of his constituents.

“A neighbor complained that there was a large truck parked on his street that was leaking oil,” he said. “So, looking at this, we found that, apart from the fact that the the truck was leaking oil that was seeping into a pond, there was nothing in city regulations preventing this huge truck from being parked there.”

Anderson said that the officials looked into parking regulations in cities and towns throughout the state to come up with an ordinance that would work in Milford.

“In many parts of Bristol, for example, there’s no overnight on-street parking allowed at all,” he said. “We thought that was too restrictive.”

He said that large vehicles can create safety issues with regard to visibility. Then there’s the issue of aesthetics — a large truck that’s always parked near or in front of your home could reduce its property value.

“Of course, we’re not looking to punish you if, for example, you’re in the process of moving or if you’ve had fire damage — things like that,” Vetro said. “Police officers will have some discretion in this regard.”

Anderson agreed. “The new regulations are aimed at flagrant violators — not for people who are moving,” he said.

The amended ordinance won’t take effect until late November, officials said.
