The Fairfax County Board of Supervisors directed its staff yesterday to draft a rezoning procedure to make developers of new homes disclose to prospective buyers any plans for nearby public housing before making a sale.

The procedure, sponsored by Republican Supervisor Thomas M. Davis, would make the pledge of such disclosure a condition of rezoning. " . . . some people in the county have been outright lied to" about public housing plans near their homes, Davis said.

Davis, of Mason District, disagreed with Supervisor Martha Pennino (D) of Centreville, who said she fears the procedure would discourage developers from building housing for low- and middle-income families. Davis said incentives would be provided to developers.

Board Chairman John F. Herrity, a Republican, delayed action on his proposal to require board approval of proposed public housing projects, an effort to gain control over the county Redevelopment and Housing Authority.

Herrity said he delayed the matter out of courtesy to Democratic Supervisor James Scott of Providence District, who was ill and did not attend yesterday's meeting. Scott, a public housing proponent, represents one of the proposed public housing projects that is the current center of controversy.

A press release from the housing authority yesterday said the agency agency "has never built a public housing development that did not receive the majority support of the Fairfax County Board of Supervisors," and added that the board has the right to approve all projects.
