Spending on a real estate appraisal for the Capt. Warren House and converting the silos at Katama Farm into wireless towers are among the decisions that will confront Edgartown voters at a special town meeting on Tuesday night.

The meeting begins at 7 p.m. in the Old Whaling Church. Moderator Philip J. Norton Jr. will preside over the 15-article warrant.

Voters will be asked to take $10,000 from the Edgartown library building committee account for real estate appraisals and engineering drawings for the potential sale of the historic Warren House property on North Water street.

The town bought the property in 2005 for $3.5 million with the intention of renovating it for an annex to the Carnegie public library. The house dates to the 1780s with Victorian-era additions. The town historic district commission ruled last December the house could not be torn down.

Today the plans for library expansion have changed and the Warren House sits vacant and crumbling. The library building committee wants to hire an appraiser to set a value on the house. Selling all or a part of the property are both under consideration.

The library committee will update voters at the special town meeting on the status of the planned move to the old Edgartown School. The town has applied for $5 million in state grant money for the project, but did not make the final cut in the first round of state funding in July.

Voters will also decide whether to convert the unused 60-foot silos at the town-owned Katama Farm into wireless towers to improve cell phone coverage in Katama. The article would allow the selectmen to enter into a lease and allow easements to the property for telephone companies. So far AT& T has been the only company that has expressed interested in the project.

Voters will also be asked to approve $5,000 for consulting fees for the Katama project and a similar project on Chappaquiddick.

In other articles on the warrant, the Edgartown Firemen’s Association is requesting $20,000 from community preservation funds for interpretive plaques for historical artifacts at the Edgartown Fire Museum. Voters will also be asked to spend $40,000 for a new air compressor for the fire department.

Other spending articles include $29,000 to reimburse the Edgartown police for final payments to a retired officer, $27,000 for installation and training on new utility billing software for the town accounting system, $10,000 for a new outboard for the shellfish department, and $4,650 for the town’s share of a Martha’s Vineyard Commission affordable housing needs assessment.

Voters will take action for a second time on a zoning bylaw amendment regulating elevated decks and porches. The amendment was approved at the annual town meeting in April, but the original public hearing was not held within six months of the meeting.
