Four candidates for the May 2 Falls Church City Council election were endorsed recently at an open nominating convention of the Citizens for a Better City, a nonpartisan political coalition which currently holds all seven seats on the council.

Those nominated as CBC candidates were:

Gary Knight, of 211 S. Virginia Ave., a planning commission member and associate manager of the U.S. Chamber of Commerce. Knight has a master's degree in public administration from American University. He has pledged to "fight off attempts to make our community indistinguishable from the rest of 'mass suburbia'" while maintaining the city's services.

Robert Hubbell, of 303 N. Lee St., a retired Agency for International Development division chief, who is making his first bid for office. Hubbell has a master's degree from Harvard University. He said he favors keeping Falls Church a residential community with good public services, low tax rates and no additional strip zoning.

Nancy Stock, of 707 Poplar Dr., a homemaker and self-described "involved citizen," who is making her first bid for office. Stock attended Aquinas College in Grand Rapids, Mich., and is vice-chairwoman of the Northern Virginia Juvenile Detention Home Commission. She is a past president of the Falls Church League of Women Voters.

Stock said she sees the major problems facing the city as "dealing with a declining school population without compromising our commitment to an excellent school system, stimulating growth of the business community while protecting the residential character of the city, and keeping our local taxes as fair and as reasonable as possible, compatible with our high standard of city services."

Incumbent City Council Member Carol W. Delong, who is also the vice mayor of Falls Church. Delong, who lives at 213 West Columbia St., has been a member of the council since 1974. She is a graudate of Rutgers University, and holds a master's degree from Washington State College.

DeLong said she is concerned that Falls Church remain a distinctive, comparatively low-density, family-oriented community, attractive to people of all ages. She emphasized that the city's school system, residential areas, recreation programs and municipal services are important to present and potential residents.

Wallace Nickel, a fifth candidate who sought CBC endorsement, was not nominated. He is employed in engineering and analysis by a communications consulting firm. Richard L. Deal of Fairfax. Nickel retired three years ago after 29 years of Army service.

More than 200 people attended the CBC open convention, which had a town meeting format and was open to all voting Falls Church residents. CBC President Roger Wollenberg called it "one of the largest conventions that CBC has ever held." It was the group's ninth convention. Ballots were cast by 199 people. No nominations were made from the floor.

The terms of four council members expire in May and three members have announced that they will not seek re-election. They are John Enright, Harold Silverstein and Edward Strait. Councilwoman DeLong's term also expires in May.

The CBC candidates have all emphasized their common goal of protecting the residential character of Falls Church, which has been a CBC priority throughout its 19-year existence, along with an emphasis on good schools.

The Falls Church Citizens for Good Government, a nonpartisan political group which is being formed to combat the CBC influence in city politics, has scheduled a public meeting Feb. 28 to approve its slate of four council candidates.

The group currently consists of "about 35 interested families," according to Charles J. Weir, acting president. At Tuesday's meeting, the group will also elect officers and vote on its bylaws. The meeting begins at 8 p.m. in the Falls Church Community Center.

The Falls Church Citizens for Good Government slate of candidates has already been picked, Weir said. They are Charles Gentry, of 109 Buxton St., an independent economic consultant who is making his first bid for office; Ann Hoverson, of 105 Jackson St., a freelance artist who is president of the Thomas Jefferson PTA and a member of the architectural advisory committee for Falls Church schools; and Weir, of 809 Villa Ridge Rd., who was an unsuccessful candidate in the 1976 City Council race. Weir holds a master's degree in public administration from American University and is a retired supervisory computer specialist for the Department of Health, Education and Welfare. He is a past president of the Thomas Jefferson PTA.

One other person will seek nomination to the Falls Church Citizens for Good Government slate, Weir said, but "the man does not want his name announced yet for business reasons."

The main goal of the Citizens for Good Government is "to bring fiscal responsibility to the City of Falls Church government," Weir said. The group promotes the expansion of the city's tax base by inducing new businesses to build in the Falls Church business area, he said. "We believe that the only way Falls Church can survive as a separate political subdivision is to create a larger tax base."
