The Board has embarked on a nationwide search for a successor to Anthony H. Griffin, who announced days after the November elections that he would be retiring this spring after 12 years as the county’s top manager.

Beginning at noon, Bulova will be online with “Ask Fairfax!” on the county’s Web site to discuss the process of finding a new county executive and take questions from the public.

Bulova laid out her priorities for her second term as chair of the 10-member board during her inaugural speech last month. These include providing more workforce housing, building a conference center and luring new industry sectors, such as the emerging field of translational medicine.

In addition to Friday’s chat, county officials have been gauging the public’s views on finding a new county executive in other ways. Supervisor John C. Cook (R) hosted a town hall Monday night that drew about 30 people interested in discussing the search for a new county executive, and the county has invited the public to participate in an online survey. As of Monday, the survey had drawn more than 1,800 responses, county spokeswoman Merni Fitzgerald said.
