What's sauce for the goose is sauce for the gander. That old adage is at least part of the message sent by the Fairfax County Board of Supervisors in approving a plan to allow industrial development next door to the Ashgrove estate near Tysons Corner, once owned by the sixth Lord Fairfax for whose family the county is named.

Taking it from the top: James C. Richards and his mother Helen sought permission to erect an office building complex on 3 1/2 acres in the 8800 block of Ash Grove Lane, near State Rte. 7 and the Dulles Airport access road.

Neighbor Wilson C. Sherman protested that the development would destroy the beauty of Ashgrove, now owned by his family. The proposed building would be about 100 yards--the length of a football field--from the onetime Fairfax hunting lodge on the Ashgrove estate.

Last month the county Planning Commission voted 6 to 1 to support Sherman's opposition. But the supervisors decided 7 to 0 Monday night to reverse that stand.

That's where the "sauce for . . . " came into play. The supervisors noted that Sherman had requested and received approval for erecting a 21-story hotel on the Rte. 7 edge of the Ashgrove property, less than 1,000 yards from the estate's dwelling and from the Richards' land. The hotel, which would be the tallest building in Fairfax County, would be part of the Sheraton chain.
