The Greenbelt City Council adopted a $3.6 million 1982-83 operating budget last week that is about $500,000 higher than this year's spending plan.

The largest appropriation is for the city's public safety department, which will receive slightly more than $1 million. The public safety budget includes $985,700 for the police department, $25,400 for traffic control and $6,500 for animal control.

The city has added two police officers to the department, bringing the total to 30 officers and one cadet, according to city spokesperson Gudrun Mills.

Other large appropriations in the new budget include $704,600 for the public works department, $668,200 for parks and recreation and $409,200 for general government administration.

In other budgetary moves, the council introduced a bill that would give most city employes an average 7 percent cost-of-living salary increase. More than $133,700 was included in the government administration appropriation to cover raises for the 85 employes.

The council also set the city manager's salary at $41,000. City Manager James E. Giese received $38,000 this year, Mills said.

Although the city's tax rate remains $1.06 per $100 of asessed value, residents will pay more to have their refuse removed. The council voted to raise the monthly trash collection charge from $7 to $8 per household.
