GROTON — Satisfied that a group of businesses sharing a common parking lot and access from Main Street had arrived at an amicable resolution to a problem resulting from an increased flow of traffic onto their property, members of the Planning Board made plans last week to vote on the Luth Karate Studio’s application for a special permit.

The move forward came at the board’s meeting of Feb. 2, when Michael Luth, owner of Luth’s Family Karate, agreed to conditions submitted by neighbor Workers Credit Union that had been derived from a traffic study conducted by the bank.

Planning to relocate his karate studio into a building at 306 Main St., Luth has proposed building an 1,800 square-foot addition to the existing structure, a situation that quickly drew the attention of Workers Credit Union, which shares a 36-space parking lot with him.

Although Luth assured board members at a previous meeting that even though the town’s zoning regulations require him to have at least 17 parking spaces for the size of his building, the most he would ever need was 10.

Luth said at the time that due to the small amount of time his business hours would overlap with those of the bank, there would never be a problem with a lack of parking spaces.

That assurance however, was contested by the bank, represented by attorney John Gallant, who said that though his client had no objection to Luth’s business, its primary concern remained the availability of parking and traffic.

One of the concerns noted by Gallant was the fear that parents picking up and dropping off children would end up waiting for them in their cars and causing lines to form that would block the common access each business used to allow their customers into the parking lot.

Adding to the problem was a third neighbor, the office of Dr. Jay Decoteau, that also shared access from Main Street through the parking area and who joined the bank in its traffic study.

In the report from the bank’s attorney dated Feb. 2, it was found that “there are clearly not enough parking spaces available for the use of the proposed project.”

The report noted that due to the kind of activity to be conducted by the proposed karate studio, the 10 parking spaces allotted to the business were very likely to be filled quickly and spaces belonging to the bank taken up afterward.

“This type of inconvenience and burden imposed upon the customers, tenants and employees of the 300 Main property is unfair and unacceptable,” concluded the report, ending with a recommendation that the board not approve the special permit unless certain conditions were met.

Among the conditions listed were demands that patrons of the karate studio not park or drop off students on the grounds of the bank or in the access way and parking area and that vehicles not doing bank business but parked in its spaces would be towed at Luth’s expense.

Luth agreed with those conditions as well as others concerned with keeping the common access way clear and in good repair and to clearly mark those parking spaces designated as his own.

Also at last week’s hearing, a number of Luth’s customers attended in a show of support, with many affirming that the karate studio would make a good addition to the town’s business sector.

“We will make sure that does not happen,” assured Luth patron Tom Fitzpatrick, referring to cars that might block the access to the parking lot.

With general agreement among the parties, planning administrator Michelle Collette was to draw up a list of conditions incorporating the findings in the traffic study. The board will reconvene on Feb. 16 for a vote on the special permit application.

Also last week, board members decided that a plan by local businessman George Pergantis to open a new restaurant on Main Street deserved heightened scrutiny in any special-permit application.

After suffering the devastating loss of the historic Groton Inn by fire some months ago, the determined Pergantis has busied himself with reopening some apartment units at the Main Street site as well as preparing to open a new restaurant in the surviving carriage house building at 128 Main St.

In a presubmission review last week, Pergantis’ engineer Jeff Brem told the board that because many items on the 8.5-acre site such as lighting and parking would not need to be changed, only a level 1 site-plan review would be necessary.

But with 104 seats planned for the restaurant and the number of parking spaces that would be needed as defined by the town’s zoning bylaws, enough questions remained for board members to entertain doubts about the request.

“I’m very reluctant to move ahead in an incremental fashion with this property,” said Chairman Russell Burke, whose doubts were echoed by other members of the board.

As a result, board members voted to consider the proposal under a level 2 review.
