HATFIELD — An additional $1.4 million for wastewater treatment plant upgrades, special legislation to allow golf carts on the town’s public ways and zoning amendments to promote cluster housing developments and permit detached accessory dwelling units are among items coming before voters at Hatfield’s annual Town Meeting.

When residents gather Tuesday at 7 p.m. at Smith Academy to take up the 28-article warrant, they will also be presented with a special funding request for the fire and ambulance department that would trigger a $66,000 Proposition 2½ tax-cap override. That override is subject to a ballot vote at town elections on May 21.

The fiscal year 2025 operating budget is rising from $14.05 million to $14.52 million, a $470,731, or 3.4% increase. The override, which adds to the $474,578 for fire and ambulance service, will allow the department to remain competitive in its pay for paramedics and cover other staffing expenses.

The added money for the wastewater treatment plant upgrades, through borrowing that will be paid back via sewer fees, supplements $12 million in borrowing approved two years ago. This comes after the Select Board accepted a lone bid for $9.39 million bid from W.M. Schultz Construction Inc. of Ballston Spa, New York.

Ensuring the project can proceed as envisioned is important, said Select Board member Ed Jaworski, noting that the money will cover the costs of two clarifiers. “Those are important so that the plant operates safely and correctly,” Jaworski said.

“We feel that while the contractor is there, now is the time do it, not to put it off, because it’s really the heart of the plant,” said Department of Public Works Director Phil Genovese.

The municipal budget doesn’t require a general Proposition 2½ override, as it did last year, but residents will be asked to apply $137,281 in free cash to cover the increases for tuition at Smith Vocational and Agricultural High School, which is up $148,461, to $722,257.

The public schools are seeing a $149,089 increase, up to $6.12 million from $5.97 million. The budget also includes salary increases comprising 2.6%.

Other spending will come from the Community Preservation Act account. The largest are $196,980 for rehabilitating Day Pond, the body of water next to Smith Academy, so it can be used for recreation, education and open space, and $185,989 for documenting, assessing and digitizing the Cutter Farm Museum contents.

Another $29,825 in CPA money goes to preserve and restore the facade, belfry and clock enclosures on the historic town-owned clock in the steeple at the First Congregational Church, $25,000 for creating an historic walking tour of homes, locations and events on Main, Maple, Elm, Propsect and School streets, with 12 to 15 bronze plaques to be purchased, and $7,000 to preserve, restore or replace historic headstones in the Hill Cemetery.

There are also a series of requests that will be largely reimbursed through state Department of Environmental Protection grants. They include $226,405 for the sewer asset management planning project, $227,765 for the stormwater asset management planning project and $171,288 for the drinking water asset management planning project.

For zoning changes, the Planning Board is supporting amending the open space development bylaw as a way to encourage more clustered housing development. The bylaw references permanent protection of open space, the various natural resources that would be protected and how the bylaw meets the town’s master plan and open space and recreation plan, as well as how it could reduce energy consumption and greenhouse gas emissions.

Accessory dwelling units, which are already allowed, would be expanded to permit detached units, giving more flexibility so they don’t have to be in the same building.

The legislation for the golf carts would make sure people can keep using them and stay safe, especially near the center of town. This will require legislation that would be filed by Sen. Jo Comerford and Rep. Lindsay Sabadosa.

Voters also will be asked to create a permanent easement for a concrete headwall and stone outlet as part of the state Department of Transportation’s project to improve Haydenville Road between Whately and Williamsburg. The request for the easement comes from Whately officials.

Other articles include using $133,500 from cable access fees to build out the community television station at Town Hall and allowing Eversource to work on a solar canopy at the elementary school.
