West Tisbury voters will be asked to pay for the final design phase of a new town police station at a special town meeting Tuesday.

Moderator F. Patrick Gregory will preside over the session which begins at 7 p.m. at the West Tisbury School. There are nine articles on the warrant.

Voters will be asked to approve a transfer of $80,000 from the overlay surplus fund to complete the final design and prepare construction documents for bidding for the police station project. The 5,200-square-foot facility will be located next to the town public safety building on State Road.

Voters have already approved a total of $150,000 for design fees. The project is expected to return to the annual town meeting in April for construction funding, estimated at $2.6 million. The public bidding process for the project can begin before the money is appropriated, allowing the town to have a better handle on costs, building committee chairman Norman Perry said.

“The advantage of doing this is we will have the bid prices locked in,” Mr. Perry said. “If at the April town meeting voters say okay, we will contact the vendor and say, let’s go . . . and start digging the next day. We felt this was the smart thing to do,” he added.

In other business, voters will be asked to approve transferring $20,000 from the general fund to the town affordable housing trust fund for future affordable housing projects. The money comes from the sale of an affordable housing lot in Bailey Park. The funds had to be placed in the general fund before being transferred to the trust.

Voters also will be asked to correct an address in an article from the 2008 annual town meeting at 250 State Road, a town-sponsored affordable housing project. In light of town covenants on the property, language in the article needs to be changed to allow property owners to obtain mortgages.

Voters will be asked to include two parcels of land at the intersection of Indian Hill and State Roads into the mixed business district, and to authorize the selectmen to dispose of two small parcels of land on Long Point Road. The parcels are located in the middle of property owned by The Trustees of Reservations at Long Point and have no access.

Voters will be asked to approve a new reserve fund intended to pay for unused sick and vacation days for retired town employees in the future. The fund allows the town to “start planning for the eventual retirement of staff,” town administrator Jennifer Rand said, “which in the next five years we could see some financial impact.”

Other articles include:

• A request for $2,500 to go toward the county retirement program;

• A request to rescind $5,000 in unspent money from the town’s $285,000 purchase of the Field Gallery.

• Payment of $800 toward the Martha’s Vineyard Center of Living cost of living adjustment fiscal 2013 budget line.
