he Fairfax County Federation of Citizens Associations will again have a lobbyist in Richmond during this year's legislative session. The unpaid lobbyist, Leslie McCauley, 24, who served in the same capacity during 1977, is a former Fairfax County resident and the daughter of Reynolds Thomas, an active member of the federation.

The federation has several priorities for the current session, according to President John Lynch:

Passage of the Charter Bill, which would make Fairfax County the first county in the state to be governed under a charter.

Passage of legislation levying a 4 per cent gasoline tax in Northern Virginia to be used for transportation purposes, without the requirement for unanimous agreement by all area jurisdictions.

Passage of legislation affecting the state's judicial system, including abolition of jury sentencing, giving judges the job of sentencing quilty defendents, creation of nominating commissions made up of judges, lawyers, and lay people to assist the General Assembly in choosing circuit court judges around the state and giving local courts the option of establishing small claims courts.

"We'll also be making sure that there is support in Richmond for the continuation of conditional zoning," said Lynch.

Under the county's current practice of conditional zoning, a developer may offer "proffers," such as preservation of trees, stream beds, the building of streets, as conditions for rezoning. If rezoning is granted conditional on the proffers, they become part of the development plan the developer is legally bound to carry them out.

At a meeting earlier this month with 10 of Fairfax County's legislators, Lynch and other federation board members outlined the organiztion's position on matters likely to come before the General Assembly.

"The meeting was very cordial," said Lynch. "Hopefully, we'll see a continuation of the close cooperation that's existed previously."

At the federation's meeting tonight, at 8 o'clock in the Fairfax Hospital Cafetorium, other legislative proposals will be outlined and voted on by the federation. A letter will be sent to each of the county's legislators outlining in detail the federation's positions, said lynch.

The federation represents about 100 citizens associations throughout Fairfax County.
