The following were among actions taken by the Fairfax County Board of Supervisors at its July 27 meeting. For more information, call 691-3187.

ROUTE 1 DEVELOPMENT -- The board, ending months of wrangling between citizens and developers over the Southeast Fairfax Development Corp. (SFDC), a private, nonprofit organization established to help revitalize the county's Rte. 1 corridor, voted unanimously to increase the number of citizens on the group's board of directors.

Since its founding in 1982, SFDC has received about $800,000 from the county. But the group has come under fire for allegedly conducting meetings in secret, favoring developers, and ignoring suggestions of county residents.

In response to these charges, the board voted to add two additional citizen representatives to the 16-member board and to require SFDC board members to disclose financial ties to developers. The board voted to permit the SFDC to go into private, executive session only for reasons allowed under the Virginia Freedom of Information Act.

However, the board also voted to allow anonymous contributions to the organization to continue.

GOVERNMENT CENTER -- The board ordered County Executive J. Hamilton Lambert to review a proposal to swap county-owned land with a developer in exchange for construction of a new county government center.

Under the plan currently being considered by the board, the county would trade 116 acres of prime development land near Fair Oaks Mall in exchange for construction of the proposed $83 million government center by the Charles E. Smith Cos./Artery Organization Partnership.

The board ordered Lambert to compare the land swap with the cost of financing the project with bonds, a measure that has been supported by the Fairfax County Federation of Citizens Associations. The board will vote on the government center proposal Aug. 3.

RADON TESTING -- The county released the results of its radon testing project, which indicate that the county does not have a major radon problem.

More than two-thirds of the homes surveyed by the county had very low levels of radon while only 2 percent had radon levels that could pose a high risk to residents. About 32 percent of the houses had "borderline" levels of the radioactive gas. The county will test these houses again to double check their radon levels.
