STILLWATER — A cell tower company said Monday it wants to demolish two existing towers and build a new tower on nearby property because it said the lease agreement the company has with the current landowner is unacceptable.

Crown Communications leases land from William Hauf at 2 Radar Road for a 190-foot cell tower. AT&T also leases a site for a 150-foot tower from Hauf.

John Stockli, the attorney for Crown Communications, told the town Planning Board that a provision allowing either Hauf or the company to terminate the agreement with just six months’ notice is not acceptable to cellphone companies.

But Hauf, who lives in San Diego, said he is willing to negotiate the terms of the lease.

“We have not talked to them recently because we didn’t know that they were not going to want to stay there,” Hauf said. “They just went off and decided to make an application without ever talking to us about what their needs were for the future.”

Crown Communications wants to build a new tower about 230 feet west of the current towers on a wooded property owned by Thomas Gorski and then terminate its lease with Hauf. The company needs a land-use permit from the Planning Board to build the proposed tower.

Verizon Wireless is Crown’s only customer at the Radar Road tower, but Stockli said that Sprint is interested in renting space if the proposed tower is built.

He also said that he believed AT&T would commit to demolishing its tower on Hauf’s property and instead rent space from Crown Communications on the proposed tower.

AT&T’s lease with Hauf has the same terms as Crown Communications’ lease.

“Upon six months’ notice, it can be terminated,” Stockli said. “That’s problematic for the carriers because of the investment in the network and the coverage areas.”

The proposed tower on Gorski’s property is the same height as the current Crown Communications tower and is narrower because it has only one pole instead of three.

“It’s really just a swap,” Stockli said. “It’s a swap and reducing the number of towers by one.”

Planning Board members said they were concerned with the visual impact since the proposed new tower is closer to some homes than the two current towers.

“Taking two towers down and putting up something that is new technology is generally a good idea,” board Chairwoman JoAnn Winchell said. “We just want to make sure because this is our first telecommunications project to review, we want to make sure that we review it well.”

The board asked Crown Communications to more thoroughly analyze the proposed tower’s visual impact and find out if the cell companies could possibly lease space on a nearby Federal Aviation Administration tower.

Hauf’s 43-acre property is the site of an old Air Force radar station that closed in 1976. He said it will cost about $800,000 to complete environmental cleanup before the property can developed.

Eventually, he said, he hopes to develop low-density housing on the property and would hope if the cell towers remain on his property that the companies would work to blend the towers into the surroundings.

“We had no problem with them remaining as long as they would be willing to cooperate to try to camouflage this,” he said. “Our intent is to work with them.”

The Planning Board has to accept Crown’s application as complete once the company provides the board more information. The board will also hold a public hearing before any final decision is made.
