A story in the late editions of Wednesday's Post regarding the Montgomery County Council's vote on locating a Metrobus depot in Wheaton incorrectly said the Wheaton Chamber of Commerce and residents living in the area favored a depot on the southeast corner of Georgia Avenue and Reedie Drive. The residents and the chamber favored the site selected by the council on the southwest corner.

The Montgomery County Council voted yesterday to build a Metrobus depot across the street from the future Wheaton subway station instead of next to the station, a move its critics said could increase the cost by as much as $2.1 million.

The 4-to-3 vote to build the depot on the southwest corner of Georgia Avenue and Reedie Drive ended a year of frequently heated debate. That location was backed by County Executive Charles W. Gilchrist; land and construction costs are estimated at $13 million.

Building the depot next to the Metrorail station on the southeast corner was favored by the Maryland-National Capital Park and Planning Commission, the Wheaton Chamber of Commerce and some residents of the area. They argued that putting it across the street would not help small businesses as much as putting it next door and that there would be too much noise and air pollution.

Council President Neal Potter and members Esther Gelman and David Scull voted in the minority. "If we have millions extra we should be fixing the streets that are death traps," Gelman declared.

Gilchrist said the estimate that the location will cost as much as $2.1 million more is grossly exaggerated and cited Washington Metropolitan Area Transit Authority figures showing the cost difference as between $100,000 and $1.2 million. He also said building the facility on the southwest corner will present less of an intrusion into the residential area.

The depot, which will have seven bus lanes, is scheduled to open in 1987.
