Fairfax Board of Supervisors Chairman Katherine K. Hanley (D), who has announced she will not seek reelection in November, has been involved in county politics nearly 20 years. Here are some of Hanley's career milestones.

1966: Hanley and her husband, Edward Hanley, moved to the county, where they raised a daughter and son. Kate Hanley, a Missouri native with degrees from the University of Missouri and Harvard, went on to teach and serve as a guidance counselor in City of Falls Church schools.

1984: Hanley was appointed to the county School Board. In 1985, she cast the only vote against the school budget, saying the county was not paying teachers enough.

1986: Charging that Republicans represented developers, Hanley won a special election to replace Supervisor James M. Scott (D-Providence). She was reelected in 1987 and 1991.

1987: A Democratic, slow-growth majority gained control of the county board. Hanley was allied with Chairman Audrey Moore, who pushed through stiff development restrictions. Five years later, a GOP-controlled board reversed the downzoning.

1995: In February, Hanley won a special election for board chairman, replacing newly-elected Rep. Thomas M. Davis III (R). In November, she beat School Board Chairman Gary L. Jones for a full term. Democrats retook control of the board.

1997: Hanley and many board members opposed Republican Gov. James S. Gilmore's repeal of the car tax, saying the loss in revenue would harm county finances.

1999: Hanley, who ran unopposed, was reelected. In her state of the county address, she noted the county's booming economic growth. In February, Hanley was elected chairman of the Metro Board.

2000: Hanley considered running for lieutenant governor but decided against it.

2001: Hanley and her husband moved from the Providence District into a condominium in Reston. Redrawn congressional district lines have made Reston part of the district represented by Rep. James P. Moran (D). The county economy, in the wake of the Sept. 11, 2001 terrorist attacks, took a hit as unemployment rose and the high-tech industry slowed. Meantime, assessments on residential and commercial property skyrocketed in the county.

2002: Hanley and board members endorsed a transportation sales tax increase, which was defeated overwhelmingly by voters.

February 2003: County supervisors got a budget proposal that would raise property taxes on most county residents for the third straight year. Hanley and board members discussed cutting the tax rate.

Tuesday: Hanley said she will not seek reelection and is mulling a run against Moran next year.
