COLLEGE PARK -- Students returning to College Park this fall may be surprised to find that free parking in the city center is practically a thing of the past.

The City Council last week voted to install parking meters in the College Park Shopping Center on U.S. Rte. 1. The council will also try to install meters in front of the7-Eleven store on Knox Road, the only remaining free parking lot in the city, according to Director of Public Services Donald Byrd. The council also voted to extend the hours of meter operation from 10 p.m. to midnight, Monday through Saturday.

The council took the combined action to deter all-day parking in the lot and loitering and drinking there in the evening, according to Council Member Lou Stengard.

The meters are expected to be in operation within two months, according to City Clerk Miriam P. Wolff.

In other business, the council increased the reward offered for information leading to the arrest of the person or persons responsible for the June 27 municipal center bombing. The city is now offering a $1,000 reward for the information, with the county offering an additional $1,000. The bomb killed Cao Ren Wu, a visiting computer specialist from the People's Republic of China, and wounded four others.

COLMAR MANOR -- The Town Council Tuesday approved its $235,000 budget for 1981-82. The projected expenditures are a 6 percent (or approximately $12,000) increase over the 1980-1981 fiscal year budget, according to Town Administrator Mike Mulligan.

BERWYN HEIGHTS -- Three part-time police officers were sworn in at Wednesday's Town Council meeting.

The town's police force now has five part-time officers and one full-time policeman. The three new officers are Kevin Paul Payne, William Michael Manning and Anthony Robinson.

In a related action, the council revised the town's police ordinance to take the community's new officers and 1978 charter into account.

In other business, the council last week adopted an organizational chart which determines the lines of authority and communications within the Berwyn Heights government. The council also adopted the town administrator job description.

According to Town Administrator John L. Fitzwater, both actions were necessary to bring the community's administrative procedures in line with the charter. Before the 1978 charter was adopted, Berwyn Heights did not have a town administrator.

The council also awarded two contracts: $18,100 to International Harvester Corporation for a dump truck and $3,200 to W.B. Maske Sheet Metal Works, Inc. of College Park for two natural gas-fired heaters.

CHEVERLY -- The Town Council is considering an ordinance to halt the practice of throwing things from cars during parades.

Although details of the ordinance have not been worked out, it is expected to thwart potentially dangerous incidents at Cheverly Day parades, according to town officials.

In the past there have been several close calls when food, souvenirs, and debris were thrown from moving cars, nearly hitting small children, town officials said.

In other business, the council discussed the future of cable television in the town. The council, which has not awarded a cable contract, is waiting for the county to make its franchise decisions.
