* George Mason University, a thriving institution, has brought more bustle to the neighborhoods around its campus just south of Fairfax City than is wanted by some of the people who live there.

Traffic on the once-quiet tree-lined streets is a particular subject of complaint, as is the difficulty of finding parking space.

Help is on the way, according to a school spokesman, in the form of 2,500 new parking spaces that will increase the capacity of the campus lots by more than one-third.

The Virginia General Assembly, in its session that ended March 8, authorized the school to sell $2.5 million in revenue bonds to add parking spaces at lots on either side of Rte. 123. The school now has 6,000 parking spaces.

Helen Ackerman, a spokeswoman for the state- supported school, said the spaces will be built over the next three to five years.

"Parking is very tight on this campus," Ackerman said. "It's a constant concern of students and the faculty. It's very hard to get parking on this campus between 9 in the morning and 1 in the afternoon."

"It would prevent people who come to events there from parking in places other than the university," said Sharon Bulova, president of the King's Park West Civic Association. "The parking situation over there is terrible."

Many complaints center on traffic problems that arise when popular events are scheduled at the school's Patriot Center arena.
