Millions of dollars in spending initiatives and the fiercely-debated housing bank proposal will be on the agenda when voters in Edgartown, Oak Bluffs, Tisbury and West Tisbury take up the annual business of their towns tonight.

Edgartown convenes its annual town meeting at the Old Whaling Church. Oak Bluffs convenes at the Performing Arts Center. And Tisbury and West Tisbury will host their meetings in the gymnasiums of their respective town schools.

Moderators will gavel the meetings to order at 7 p.m.

In Edgartown a hefty agenda of 95 articles in two warrants is expected to possibly mean a two-night affair.

Moderator Sean Murphy will take up the gavel for the first time. He will be joined on stage by other new faces in town leadership: town administrator James Hagerty and town clerk Karen Medeiros.

A $38 million town budget, a slew of waterfront improvements and whether to replace the Katama Airfield hangar are all up for consideration.

In Oak Bluffs voters will hear reports on school spending, which is on the rise, and other budgetary matters.

A $30.9 million operating budget, community preservation initiatives that include restoration of the East Chop Light and a study to identify fish predators to control toxic jelly fish in Farm Pond are among the varied items voters will consider.

In Tisbury the struggle to find consensus on a new town school appears to be on a fresh track this year, with selectmen and school committee members preparing to present a new proposal for a $400,000 feasibility study.

Voters will take up a $28.8 million operating budget and will confront a number of major decisions relating to wastewater management.

In West Tisbury a first-time rooms tax is up for consideration as the town considers ways to bring in more revenue to offset rising expenses.

Environmental protection is also a major theme this year. Voters will be asked to spend money to begin to carry out the recommendations of the Mill Brook Watershed management plan, an outgrowth of a years-long study completed last year.

And thanks to an initiative sparked by a group of up-Island school children, voters will consider a bylaw that would ban the sale of small-sized plastic bottles in town.

Calling themselves Plastic Free MV, the fifth and sixth graders approached selectmen in Chilmark, West Tisbury and Aquinnah and petitioned to have the bylaw placed on town meeting warrants.

The students have screened documentaries, held public forums, printed T-shirts, handed out fliers, taken to social media and spoken on the radio.

They aren’t old enough to cast votes at town meeting, but their youth also draws attention to their cause.

“I feel like being a kid helps and hurts what we’re doing,” said sixth grader Quinlan Slavin.
