BATH — The Planning Board on Tuesday reviewed a sketch plan for the third phase of the Wing Farm business park. The board will vote on more detailed plans later in the fall.

Although the 25-acre, nine-lot phase will be built entirely in West Bath, state law requires the project to get city approval because of its proximity to the Bath city line, according to project consultant Jeffrey Aceto. A road in Bath also runs across the border into the West Bath phase.

The existing King’s Highway that leads from Wing Farm Parkway in Bath into the West Bath phase will be improved, Aceto said; approximately 300 feet of that road sits in Bath. All utility truck access will come from Bath, he explained.

A traffic study will be conducted in the area of the Bath intersection of Wing Farm Parkway, Congress Avenue and Centre Street to determine the impact of added vehicle volume caused by new Wing Farm development. The two municipalities will submit an application to the Maine Department of Transportation for a traffic movement permit.

Aceto said the permit is required when a project triggers more than 100 trips in a peak hour, such as 5-6 p.m. on a Friday. The permit addresses extra traffic caused by both the second and third Wing Farm phases, he explained.

The second phase, also in the works, is about 65 percent on the way to being shovel ready, Aceto said.

The zoning in West Bath in the area of phase three is almost identical to that in Bath, he explained. It allows uses such as light manufacturing, warehousing and professional offices.

“You could find a small electrical contractor in there, you could find a small call center in there,” Aceto said. “Those are the things it’s zoned for, and that’s a pretty easy assumption that that’s what’s coming in both phase two and three.”

Aceto’s firm, Sitelines, will next submit a preliminary subdivision application in October, followed by a final application in November or December. Construction may begin next year.

“We’re trying to get this all in place permitting-wise by the first of the year,” he said.

Whereas the planning boards of Bath and West Bath would normally be required by state subdivision law to meet jointly to address those applications, the Bath Planning Board on Tuesday voted unanimously to waive that requirement so that the two communities can meet separately.
