Transportation Secretary Ray LaHood announced Monday that he has appointed a new accountability officer to monitor the Metropolitan Washington Airports Authority, the entity responsible for overseeing construction of the $5.6 billion Silver Line rail extension.

Lynn Deavers, 30, a career lawyer in the U.S. Department of Transportation’s Office of General Counsel, will replace Kimberly Moore, who is leaving the position to take a job with the House Committee on Transportation and Infrastructure later this month.

“I congratulate Lynn on her new role and I am confident that as the Accountability Officer, she will help further ensure that MWAA’s policies and practices meet the high standards of ethics and fiscal responsibility that the public expects,” LaHood said in a prepared statement.

Moore, a former Virginia prosecutor, was appointed to the job in July and worked closely with authority officials to revise travel and ethics policies following reports of expensive travel by board members and irregularities in contracting and hiring. In addition to the Silver Line project, which will provide a Metrorail link to Tysons, Reston and, eventually, Washington Dulles International Airport, MWAA also oversees Dulles, Reagan National airports and the Dulles Toll Road. In November, MWAA was the subject of a scathing inspector general’s report.

Like Moore, Deavers will report directly to LaHood.

Deavers joined DOT in 2011 after five years as a litigator with Dow Lohnes. At the Department of Transportation, Deavers has focused on ethics, oversight and procurement issues. She is a former litigator and a 2006 graduate of George Washington University Law School.

Rep. Frank Wolf (R-Va.) is expected to introduce legislation this week to create an inspector general for MWAA.
