Members of the two Virginia legislative committees, which will recommend how the state's legislative and congressional districts are redrawn, will hold separate hearings in Northern Virginia next month.

The first -- and possibly most controversial -- hearing will be at 9:30 a.m. March 13 at George Mason University. The hearing, sponsored by the House Privileges and Elections Committee, will focus on redrawing boundaries for House of Delegate districts in the Washington suburbs.

The second hearing will be at 3 p.m. March 16 at the Dulles Marriott and will be sponsored by the Senate Privileges and Elections Committee. It will focus on new boundaries for Northern Virginia senate districts.

At both hearings, testimony will be allowed on the question of redrawing the two Northern Virginia congressional districts to fit population changes outlined in the 1980 census.

Del. John D. Gray (D-Hampton), chairman of the House Privileges and Elections Committee, has announced that he believes Fairfax County should have only 11 delegates to the General Assembly as a result of the census. Area legislators have said they will press for 12, citing population growth in the county, Virginia's most populous jurisdiction.

Individuals wishing to address either hearing are requested to contact Jack Austin, Division of Legislative Services, P.O. Box 3-Ag, Richmond, VA. 23208 by March 7 for the House hearing and March 13 for the Senate hearing.

The General Assembly will reconvene in Richmond on March 30 for a week-long session devoted to redistricting and to considering vetoes from its just-ended regular session.
