Selectmen on Tuesday closed the warrant for April's annual Spring Town Meeting, placing 21 items on the agenda.

At that April 27 meeting, voters will be asked to appropriate money to rehabilitate the Onset boat ramp, fix up the Oakdale playground, and construct new school tennis courts.

Other items include a proposal to ask the state to change the way affordable housing is counted in the town, allowing mobile homes to be counted.

There are still a few weeks before the warrant is closed for the separate Special Town Meeting, which will be run as part of the regular meeting. And town officials have not yet made their recommendations on any of the items. But, with spring Town Meeting a mere two months away, the Selectmen's Tuesday vote provides voters with a good idea of what they will be asked to consider:

One item will ask the state Legislature, by way of a"home rule" petition, to categorize manufactured homes in Wareham as “affordable housing” for Chapter 40B purposes.

State law Chapter 40B, designed to encourage the development of housing affordable to low and moderate-income people, penalizes communities in which less than 10 percent of the housing stock is considered affordable -- by allowing developers to avoid local regulations if constructing affordable housing.

Because of Chapter 40B’s definition of affordable housing, Wareham has never met the 10 percent threshold. If the roughly 1,100 units in the town’s mobile home parks were to be considered affordable housing, the town would easily meet the 10 percent requirement.

There are also three Community Preservation Fund items on the agenda.

One seeks $100,000 to allow the Harbormaster Department to rebuild the deteriorated 12th Avenue Onset boat ramp.

The second seeks $90,000 to build three tennis courts at the Wareham High School./Middle School property. High School tennis coach Geoff Swett said he has raised $90,000 in private funding that will go toward the project if it can garner the $90,000 in Community Preservation funds.

The third seeks $45,000 to enable the Wareham Open Space Committee to rehabilitate the Oakdale Playground at 23 Apple St.

The state Community Preservation Act was adopted by Wareham voters in April 2002. The funds come from a 3 percent surcharge levied on residential property above the first $100,000 of assessed property. The state partially matches the locally raised funds. That money must be used for historic preservation, affordable housing, preservation of open space or recreation.

Voters will also be asked to appropriate, borrow or transfer money for a feasibility study for the installation of a new roof and boiler system at Decas Elementary School.

School Business Manager Michael MacMillan said he aims to get the project in the accelerated repair program of the Massachusetts School Building Authority, a program that reimburses the town for up to 68 percent of project costs. That is the same program used for the Wareham High School roof repair. The state covered $1.8 million of the $2.7 million price tag for that project.

The most significant business at the annual Town Meeting is to approve the town budget. With a $2.2 gap between projected revenue and projected spending -- and a state requirement that any town budget be balanced, Town Administrator Derek Sullivan, Selectmen, and the Finance Committee are still working on what will be presented to voters.
