The Fairfax School Board is scheduled to consider a plan next Thursday that would speed up renovation projects and new construction at several county schools. As a result, fewer trailers would be needed as classrooms, officials said.

School officials are proposing to sell 35.5 acres owned by the board on Pohick Road in Springfield. The sale would bring in about $12 million that would go into the school construction fund.

Separately, the county Board of Supervisors has scheduled a public hearing on the proposed sale for Oct. 18. No time has been set for the hearing. At their meeting Monday, the supervisors also said they wanted to establish a process for such sales, because there are about 15 other parcels throughout the county. School officials estimate the county has more than $1.3 billion in unmet capital needs.

Here is a breakdown of how the land sale would affect county schools, according to officials:

* A new elementary school planned in rapidly growing west Fairfax would be built three years ahead of schedule, opening in 2006, and saving about $2 million.

* Much-needed classroom space would be added in central Fairfax, eliminating the need to place 30 trailers at schools in that area by 2008.

* Another planned elementary school at the Coppermine site in the McNair Farms area of the Hunter Mill District would open two years ahead of schedule, saving more than $2 million. No opening date has been set.

* Twelve school renovation projects planned between 2004 and 2008, including the completion of Woodson High School's renovation, would have their start or finish date moved up six to nine months ahead of the current schedule. Among other schools where work would be accelerated are Graham Road, Great Falls, Mount Eagle and Vienna elementary schools.

Renovations that would be accelerated by nine months to a year include those at Beech Tree, Franconia, Lake Anne, Oakton, Stenwood and Westlawn elementary schools.

Superintendent Jack D. Dale said in a news release, "With the sale of this parcel of land, the school system can reduce its dependence on trailers as instructional spaces and provide more appropriate spaces for our students to learn."

People who want to speak at the public hearing next Thursday should call 703-246-3646. The 8 p.m. meeting is at Jackson Middle School, 3020 Gallows Rd., in the Falls Church area.
