WATERVILLE — The Waterville City Council has approved a three-year contract with city clerical workers and administrative assistants.

City Manager Michael Roy said Thursday that the agreement will provide employees who are members of the American Federation of State, County and Municipal Employees Council 93 with cost-of-living wage increases of 1.5 percent in 2011-12, plus 2 percent in 2012-13 and 2.5 percent in 2013-14.

The council approved the contract at its meeting Tuesday night.

Roy also encouraged Ward 4 residents 18 years of age and older interested in being a city councilor to submit a letter of interest to the city by 5 p.m. Thursday, July 14. The appointed person will serve a council term until Dec. 31, which is the remainder of Dana Sennett’s term. Sennett resigned recently after he was elected mayor.

On Tuesday, Roy said the council also accepted ownership of two vacant buildings adjacent to The Chez on Water Street. Roy said the city plans to demolish the buildings, which were abandoned because taxes were not paid, by October.

The council also accepted a 2011 Edward Byrne Memorial Justice Assistance Grant totaling $14,871. Roy said the police department will use the money to purchase equipment and make technology upgrades.

At Tuesday’s meeting, Roy also announced the resignation, effective Aug. 4, of finance director Robert Boshen.

Roy said Boshen, who has been employed by the city for about five years, is taking a job in Falmouth.
