BROAD RUN HIGH SCHOOL DESIGN -- The School Board approved a preliminary design for the new high school proposed for the Broad Run area, calling for a 258,000-square-foot building to house 1,580 students.

The school would be located on 57 acres on Route 642 between Route 659 and the village of Ashburn.

Approval of the preliminary design by Reston architects SHWC was the third step in a seven-step plan to open the school by fall, 1994. The board previously hired the architects and approved a set of basic space requirements. Next March, it plans to approve a final design, followed by approval of site and building plans in March, 1992. Construction is expected to begin in May, 1992.

The cost of the school was originally estimated at at $34 million, but would be reduced to $32.2 million under the preliminary design plans. Many school and county officials object to the cost. A payment plan would have to be approved by the School Board and the Board of Supervisors before construction could begin.

The preliminary design, which cost the school system $155,000, also calls for parking for 520 students, 150 staff members and some visitors. There would be a lighted football stadium, the largest in the county, seating 3,000 people. There also would be a track, a lighted baseball field, two softball fields, practice fields and six lighted tennis courts.

The school would be completely accessible to handicapped people, with wide doorways and ramps.
