In honor of Public Works Week, proclaimed by Mayor Vincent C. Gray (D), the city recognized some of its Department of Public Works employees on Wednesday.

Among the honorees was Loretta Robinson, a stern-faced parking enforcement officer.

In his remarks on Robinson, DPW director William O. Howland explained that a successful parking enforcement officer has to be “aggressive.”

Robinson said she writes 50 or more tickets a day. She cracked a small smile. “I try to be fair with them,” she said.

Also honored at the mayor’s weekly news conference Wednesday was tow truck driver Frank Hagans, who, in an ironic twist, had to move his truck out of a street parking spot reserved for D.C. Council members. Howland joked: “His vehicle is the only one that can tow his vehicle.”
