BY PAULA MINAERT — Speed cameras will probably be installed in the city by March or April, depending on council actions and approval, says Police Chief Douglas Holland. At its December 5 meeting, city council members reviewed a proposal by Affiliated Computer Services, Inc., which has other such programs in the area. Five streets will be analyzed for cameras: Baltimore Avenue, East-West Highway, 42nd Avenue, Adelphi Road and Ager Road. ACS will contract with a third party to conduct the site analysis.
