ROCKLAND, Maine — A majority of city councilors agreed Monday night to allow fitness centers to be located in the city’s industrial zones as a way to attract two companies into the community.

The council voted 4-1 to amend the city’s industrial zoning laws to make health and fitness facilities a conditional use.

The change had been requested by real estate agent Douglas Erickson who said he had a client who had a contract to purchase 15 Merrill Drive in the Rockland Industrial Park. The potential buyer wants to start a window manufacturing business in the 21,000-square-foot building.

Erickson has said, however, that to make the sale work, the company needs to lease out about 8,000-square-feet. The company had a gymnastics business that wanted to rent space there because the building has ceilings high enough for its needs.

But fitness centers were not allowed in industrial zones in Rockland.

Councilor Adam Ackor said in other communities it is not unusual for gyms to be located in industrial areas.

But Councilor Valli Geiger argued strongly against the zone change, calling it spot zoning.

“This makes no sense,” Geiger said, voicing concern about children walking to the gymnastics center while 18-wheelers pass by on roads that have no sidewalks.

Councilor William Clayton pointed out that the South School, an elementary facility, is located near the Industrial Park and that those same trucks pass by it. Geiger pointed out that the school has sidewalks along the road.

She was outvoted by the other councilors, however.

Erickson said after the meeting that he expects the window manufacturer to complete the purchase of the property by the end of the month, at which point more information about the businesses can be released.

In other Rockland City Council zoning issues dealt with at the Monday night meeting, the council voted unanimously to postpone a vote on a proposal by Geiger to exempt more new homes in Rockland from the requirement that sprinklers be included when they are built. The proposal would get rid of the requirement that a home be located within 1,000 feet of a fire hydrant in order to be exempt.

Geiger said the existing ordinance remains onerous.

Assistant Fire Chief Adam Miceli said the Rockland Fire Department remains concerned about any further exemptions in the law.

Ackor said he also saw no reason to water it down.
