The Fairfax County Board of Supervisors has approved construction of Pacific Dulles Technology Center on a seven-acre triangle between the Dulles airport access road and the Herndon Parkway.

The project is to be developed by the Dulles-based Batman Corp., headed by Bahman Batmanghelidj.

The twin glass buildings will each be divided by center atriums. Each will be seven stories high. "The buildings present a very contemporary design," according to Ronald Cashion, director of planning for VVKR Inc., a Washington firm that is designing the project.

"We will start construction in early summer of 1985," said Bob Newbill, a spokesman for the Batman Corp.

The approval of the rezoning of the tract from residential to industrial came after many months of negotiations between county staff members, attorneys and developers which eventually led to a plan that met almost every criterion of the county's master land use plan for the Dulles Road corridor.

The site had been zoned for residential uses but the coming of the Dulles roads and the Herndon Parkway had virtually assured that the area would not be developed that way.

With little fanfare, after hearing favorable reports from both the county planning commission and the planning staff, the board approved the project after the developer agreed to make major improvements to Monroe Street which is the office park's main access point.

The developer also agreed to try to institute several traffic management systems in exchange for the rezoning.

According to Charles Shumate, attorney for the corporation, the developer will try to implement a program involving priority parking for those who use van pools or car pools to get to work. Parking spaces will also be set aside for bicycles. In addition, a traffic coordinator will be on staff to match up potential car pool and van pool riders.

The project represents a consolidation of several parcels of land that were needed to bring the project up to the county's requirements for projects that are to be built within what is considered to be the high visibility corridor all along the Dulles Airport Road and the parallel toll lanes from Reston to Washington Dulles International Airport.

"The initial submission failed to satisfy the design criteria for the Dulles corridor," said Fairfax planning staff member Carlos Montenegro. There were elements regarding "access, design, siting and parcel consolidation that needed addressing in the original application," Montenegro said.

Shumate said the plan "proves that a developer can work with the county staff" to develop a plan that the staff can feel comfortable recommending to the board of supervisors for approval. He said the project "should set a design standard" for the area.

He said the process was not easy. "We expanded our development team and the land itself" before coming up with this plan, he said.

As approved, Pacific Dulles will include 223,000 square feet of office space. Buildings will have two fronts. The facades facing the toll lanes will be screened by existing trees. The entrance closer to the Herndon Parkway will include a common entry plaza.

The structured parking will not be visible from the Dulles corridor, Shumate said. That is in keeping with the county's plan for the area.
