The City of Boston expects to add a small number of employees in the coming year, a significant change for a payroll that has slashed more than 1,100 positions since 2009.
The budget Mayor Thomas M. Menino is expected to present Wednesday to the City Council anticipates that for only the second time in the last decade, the city will be able to avoid dipping into its rainy day fund to pay bills.
And city departments may even make some discretionary purchases, such as five rock climbing walls, at a cost of $25,000 apiece, to lure more teenagers to community centers.
Part of the reason for Boston’s fiscal good fortune: Health insurance costs are expected to decline by $26.3 million in the coming year, the first drop in spending on the employee benefit in memory. A deal struck last year with Boston’s municipal unions means workers pay a larger share of premiums and higher copayments at doctors’ offices, pharmacies, and emergency rooms.
A change in state law also forced retirees eligible for Medicare to join the federal program, which lowered the city’s insurance costs for roughly 5,000 former employees and their dependents.
The health care savings will have an immediate impact, especially when coupled with an anticipated $90 million increase in revenue from taxes on property, hotel rooms, meals, jet fuel, and fees from building permits.
It means Boston’s bottom line is expected to be better than since the world plunged into a deep recession.
“It’s a good budget that delivers for the people of Boston,’’ said Meredith Weenick, the city’s chief financial officer, who added a note of caution about the coming years. “Recovery from this recession will be slow. [Next year] the city will face familiar challenges of increasing health insurance and pension costs and other expenditure pressures.’’
The cost of health insurance is expected to increase, quickly eclipsing the savings from the agreement with organized labor. Boston is renegotiating contracts with its municipal unions, which means salary costs may increase. And although tax revenues have grown, money flowing into city coffers may not be enough to sustain healthy growth.
“The next couple of years are still going to be tight years for the city,’’ said Samuel R. Tyler, president of the Boston Municipal Research Bureau, a fiscal watchdog funded by business and nonprofits. “It’s a stabilizing budget that allows some increases, but recognizes the fact that the next year will be even more difficult,’’ Tyler added.
In a breakfast meeting Wednesday at City Hall, Menino is scheduled to present his $2.4 billion budget proposal to the City Council.
The plan would boost spending by 2.5 percent, an increase of $60 million that essentially keeps pace with rising costs. The council will hold hearings over the next several months before voting on the budget, which would go into effect July 1.
In his plan, Menino would hire 219 full-time employees to a municipal payroll that numbered 16,173 on Jan. 1, 2012. Many of the hires would take the place of retirees and others who have left the city’s workforce, administration officials said.
The spending plan would add 107 police officers, firefighters, and emergency medical technicians. Public safety staffing would not actually increase overall, except at the Fire Department.
The administration would like to hire 65 full-time employees at the School Department to teach special education and students learning English. The budget would add nine positions at the city department overseeing major capital initiatives such as the $115 million renovation of the Ferdinand building and other investments in Dudley Square.
The budget anticipates a $7.8 million cut in state aid, a significant source of income for the city that has dropped precipitously in recent years.
The amount the city will receive from the state will not be finalized until Beacon Hill lawmakers approve a budget.
The city’s $90 million increase in revenue is driven in large part by a 2.5 percent increase in property taxes.
High oil prices are expected to increase the city’s proceeds from its jet fuel tax by roughly $1 million. The hotel room tax, which Boston increased in 2009, is predicted to net an additional $7 million. And the meals tax - a 0.75 percent surcharge on bills at diners, take-out joints, and fine restaurants - is anticipated to generate $2.3 million more.
“Although we were opposed to the local option meals tax, we are happy to see that the revenue has increased,’’ said Stephen J. Clark of the Massachusetts Restaurant Association. “That means people are eating out.’’Andrew Ryan can be reached at email@example.com. Follow him on Twitter @globeandrewryan.
