New Arlington County Manager Barbara Donnellan has appointed county chief financial officer Mark Schwartz to her former position of deputy county manager. Schwartz served as acting deputy county manager during the seven months from 2009 to 2010 that Donnellan served as acting county manager.

Schawartz, who holds a bachelor’s degree from Harvard and a law degree from Penn, has overseen the county’s budget and bond sales since 2005.

Also today, Donnellan appointed William F. O’Connor III as director of the Department of Environmental Services. The department manages county roads, sewers, trash services, environmental initiatives and building projects.

O’Connor had been serving as director of design and construction for Arlington Public Schools, where he has been involved with the design, planning and building of three new high schools.

O’Connor’s appointment is effective Nov. 8. Schwartz’s appointment is effective immediately.

“Mark’s extensive background in financial management, strategic planning and administration, and his strong belief in the ability of local government to effect positive change, makes him the natural choice for this key position,” Donnellan said in a statement. “Bill understands both our community and the challenges of running the County’s largest department. His wealth of experience in the public and private sectors will be invaluable to a department that is responsible for everything from capital projects to maintenance of our water, sewers and streets.”
