The following were among actions taken at the July 11 meeting of the Arlington County Board. For more information, call 558-2261.

NEW COUNTY MANAGER -- The board unanimously voted to appoint Anton S. Gardner, 42, Arlington county manager. Gardner, who has acted as county manager for the past several months, was formerly Arlington's deputy county manager. He served under Larry J. Brown, who left the post in April to become county administrator in Hillsborough County, Fla.

Gardner, who began working for the county in 1971 as an administrative aide, will supervise a county work force of 2,800 employes and help manage a $319 million budget. His salary will be $85,000 a year.

Gardner, who also is a former director of the county's Department of Management and Finance, said that one of his major goals is to help ensure affordable housing in Arlington. He said he supports a proposal to allow the nonprofit Arlington Housing Corp. to buy a section of the Lee Gardens apartment complex to preserve it as moderate-cost housing.

The complex, which is located off Arlington Boulevard across from Fort Myer, is owned by the Artery Organization of Bethesda, which began renovating the 961-unit complex last month. The renovation is expected to displace thousands of the complex's predominately Hispanic residents.

BALLSTON PROJECT GETS OK -- -- The board unanimously approved a request by the John G. Shooshan Co. to build a 10-story residential building and an eight-story office building on Fairfax Drive between North Randolph and North Quincy streets. Dubbed Quincy Street Station, the project is expected to cost $44 million.

GROUP PRESENTS REPORT -- The Arlington-Falls Church Ad Hoc Planning Committee recommended to the board that it undertake parking and traffic studies of the commercial area near the East Falls Church Metro station in the board's continuing efforts to control growth there.

But the committee generally concluded that current zoning regulations are adequate to maintain such control.

Last summer, officials from Arlington and Falls Church, hoping to avoid creating intense developement such as that around the Ballston and Rosslyn Metro stations, set up the joint advisory panel to recommend how to coordinate land use and zoning in the area.

The 35-acre business area, which extends along Lee Highway between I-66 in Arlington and Columbia Street in Falls Church, is located close to residential neighborhoods in both jurisdictions.

In its report, the committee also recommended that the council retain neighborhood retail stores and that the Falls Church Fire Station on Washington Street be renovated in its current location.

The Falls Church City Council will consider the report this week.
