Tisbury voters will face the task of cleaning up old messes on a number of fronts at this year’s special town meeting, on Tuesday.

Wastewater which used to be dumped into the waters around the Island, garbage disposal on shore, neglected and abandoned buildings in town, people who don’t shovel their sidewalks after it snows, the consequences of profligate energy use: These are the literal messes.

And there is also the huge financial mess, which confronts Tisbury no less than other towns and states all across America, of liabilities owed to public sector workers, for which no provision has been made.

The mess which is referred to on this year’s warrant as OPEB (Other Post Employment Benefits) has accumulated over decades in which no money was set aside to address the mushrooming liabilities — mostly for health care — to former employees.

In Tisbury, that unfunded liability now stands at around $13 million, and will continue to grow in line with the increase in health care costs.

Article six seeks approval for the town to assess additional funding of $100,000 per year to go towards meeting that current liability.

Article seven is directed at funding postemployment benefits for future employees, by including their cost as a line item in departments’ future budgets.

Article eight on the warrant deals with more literal mess: the refuse generated by the town.

Almost 20 years ago, Tisbury, along with Oak Bluffs, withdrew from an Islandwide refuse disposal arrangement and set up their own scheme for waste disposal.

Two years ago discussions began about once again having a regionalized approach to trash. And now, voters are to be asked to formally approve rejoining the grandly-named Martha’s Vineyard Refuse Disposal and Resource Recovery District.

Next up, they will be called upon to do their bit towards keeping the seas around this tourist Island clear of waste, including human waste, pumped from boats.

In accordance with a state requirement that they now pump out on shore, the Steamship Authority wants to do it here for ferries berthed in Vineyard Haven.

This would mean some 5,000 gallons a day going into the Tisbury sewer system.

Meanwhile over recent months, Tisbury selectmen have complained repeatedly about poorly maintained and vacant buildings. Article 11 seeks to amend town bylaws to enforce better maintenance.

Failure to keep properties neat, tidy, sanitary and safe will, if townspeople approve, incur a fine of $300 a day for each day of continuing violation.

Another bone of contention over the winter months has been snow removal. The town has repeatedly warned, and ticketed, property owners who do not clear their sidewalks. Selectmen have expressed the view that some owners found it cheaper to pay the current $20 fine than to remove the snow. Thus they now propose a graduated scale of fines: $50 for a first offence, $75 for a second and $100 for every offence thereafter.

Four articles on the warrant, numbers 10, 12 13 and 14, relate to town efforts to have Tisbury designated a “green community” and so become eligible for special state grants.

The first of these articles would amend the building code to require new residential and commercial construction to meet stringent energy efficiency standards under the state’s so-called Stretch Code.

The second, three-page long article relates to the “creation of new, large-scale ground-mounted solar photovoltaic installations,” and seeks to set standards for their placement, design, construction, operation monitoring and ultimate removal.

The town itself is planning to install a solar array large enough to provide for the power needs of all its municipal buildings, through the Cape and Vineyard Electric Cooperative.

Article 13 would provide for ‘as-of-right’ siting for alternative energy projects, meaning they cannot be prohibited, although they can be “reasonably regulated.”

Finally, article 14 would provide for expedited permitting for renewable energy projects.

The 16-article warrant also includes the usual array of housekeeping items.

The meeting begins at 7 p.m. on Tuesday at the Tisbury School gymnasium.
