On the literal eve of Tuesday’s Falls Church City Council election, both incumbents seeking re-election stuck to their Council duties tonight, arduously working through the line-by-line details of the City’s Capital Improvement Plan for the Fiscal Year 2011 budget, while others of the candidates were working phones, crafting e-mails and preparing to be up before the crack of dawn to work the polls from their 6 a.m. opening to 7 p.m. closing tomorrow. Vice Mayor Hal Lippman and Councilman David Snyder, both seeking re-election, showed their commitment to their work by contributing actively to lengthy discussions on the City’s priorities for its capital improvements, while a third of the eight candidates in Tuesday’s race, Barry Buschow, also held forth as an observer at the meeting.
