Planning Board members on Tuesday objected to an access road at the Rochester Crossing property, saying the initial plans will pose traffic problems and must be redrawn.

The board, along with two neighbors, said blueprints for the 500-foot road should better accommodate traffic exiting and entering the property onto Route 58.

Rochester Crossing LLC owns the 30-acre site. In 2009, there were plans to attract retail on the property, but the recession halted development. Recently, the group Colbea Enterprises proposed a convenience store and gas station on the site.

Colbea representatives met with the Planning Board last month for a site plan review and public hearing. The station would have six gas pumps and a 40 foot by 90 foot store with a drive-up window.

Rochester LLC representatives Phil Cordeiro and Richard Serkey attended Tuesday’s public hearing. The road is a different project than the gas station and requires separate approval from the board.

Planning Board Chair Arnie Johnson said he was uncomfortable approving the road before he had more information about the volume of traffic on the site. Without knowing specifics, he said the road’s location might need to be changed.

An engineer, Cordeiro said the blueprints represented a “best guess from an engineering standpoint.” As the project develops, its specifications will be revisited. The initial road would allow access to the gas station with some flexibility for the future.

“It’s like building a road in a subdivision, but not the driveway because you don’t know where the homes will be built,” Cordeiro said.

After touring the site, the police chief and board members requested that traffic leaving the site only be allowed to take a right turn onto Route 58. Cordeiro said he altered the plans to reflect request.

Ribbed concrete about two inches in height would be installed at the exit, along with signs, to direct traffic.

Cordeiro said the concrete allows easy access to the site for emergency vehicles and plows.

Johnson disagreed. He said a traffic island was needed to prevent cars from turning left. Police Chief Paul Magee was unable to attend the hearing, but told Johnson more safety measures are needed.

“The roadway may not be sufficient to handle traffic on the lot,” Johnson said.

Louise Hebert, who lives near the site, said truck traffic was an ongoing issue there. Often, the truck drivers will ignore no parking signs and leave vehicles on the side of the road to purchase items at a convenience store nearby.

“It’s a very dangerous intersection there, and there’s at least one accident a month,” Hebert said. “My main concern is the safety on Route 58 more than anything else.”

She said the truck drivers will sometimes block her driveway or park on either side, which makes it difficult to exit her home in the morning.

Cordeiro said he will return to the board with changes. The hearing was continued to July 8.
