The Prince George's County Council, looking ahead to a widely-predicted budget crunch next year because of the new voter-imposed ceiling on property tax revenues, moved yesterday to force local government agencies to submit detailed cost-cutting plans.

The council gave its approval to resolution introduced by Councilman William Amonett that would equire the cost-cutting reports and ask incoming County Executive Lawrences J. Hogan to review the county's purchasing and personnel laws for potential cost-cutting revisions.

The council is expected to approve resolution next week during its last legislative session before the Dec. 4 inauguration of Hogan and three new council members.

The resolution also ask Hogan, who will be involved in negotiations with 11 different unions next year, to use wage and fringe benefit guidelines "that are consistent with the President's anti-inflation program," which sets a 7 percent wage increase standard.

Amonett said yesterday he had worked on the proposal for almost a month, and that the all-Democratic council's action was not intended as a check on Hogan, a Republican who defeated Democratic party leader Winfield M. Kelly Jr. by a wide margin in the general election earlier this month.

"We are not usurping the executive," Amonett said. "But we have to start getting ready for our budget review. We have a tough job to do this year, and this just gives the various department heads an opportunity to start now."

The measure would require agencies to submit reports listing areas where productivity can be improved, cost-saving measures already in effect, and stating plans to "raise the cost-consciousness of agency employes."

Amonett said he hopes his resolution will motivate Hogan to alter the personenel and purchasing laws, which he says "are simply not working out." Merit increases and promotions are too easily granted under the system, he said, and large supply purchasing contracts often are made that carry higher prices and lower quality than retail sales.
