The Renton City Council adopted the city’s 2010 budget Monday night that includes 35 layoffs and the loss of some popular community programs, such as the Summer Teen Musical.

The budget, little changed from what Mayor Denis Law proposed in October, is a reflection of the tough economic times facing the city that have reduced the sales tax and property taxes, key sources of city revenue.

Law had briefed the City Council early on about what was in the budget proposal, including the challenges facing the city. With money so tight, there was little room for debate, Law said.

“We’re clearly protecting all of our core responsibilities,” said Law after the meeting, which include public safety.

The budget includes about $98 million in the city’s general fund that pays for day-to-day operations and $29 million for capital projects. The rest of the budget is dedicated to other specific purposes.

The most difficult part of the budget process was laying off 35 employees, Law said, who are out of work not because of their job performance but because of the recession.

The community will notice some of the ramifications of the budget cuts this spring with the loss of some parks programs, Law said.

Supporters of the popular Summer Teen Musical asked that the city keep money in the budget for the summer tradition. This is a case where the city would encourage community partnerships to keep such programs alive, Law said, similar to the successful community fundraising effort that led to off-leash dog park near the Cedar River.

The budget is 3.5 percent less than the budget adopted for 2009.

The cuts in services are broad-based; protected from layoffs are commissioned police officers and firefighting crews.

The property tax rate was set in such a way that the city can bank some of the revenue for use in future years.

With the slowing economy, the preliminary projections indicated a gap of about $6 million between revenues and expenditures, a shortfall of more than 6 percent of the general fund budget.

The Community Services Department will reduce seasonal/part-time staff by 80 workers. Those cuts will eliminate the Summer Teen Musical, close some recreation buildings and reduce or eliminate summer youth programs.

In the Police Department, while there are no reductions that compromise response times and public safety, proposed cuts include administrative and clerical staff. This will result in police officers assuming some of those functions.
