Mary Ann Williamson, whom Gov. Rick Perry appointed to the Texas Water Development Board last summer, has resigned, the governor's office confirmed on Tuesday.
Williamson was one of three full-time board members heading up the agency, which is the state's main water infrastructure bank. In her resignation letter sent Jan. 13 to Perry, Williamson wrote, "As a result of recent developments and after thoughtful consideration, I will resign as a member of the Texas Water Development Board (TWDB) effective January 31, 2014. I believe this will be in the agency's best interest as I am unable to commit the necessary time to be a member of a full-time board."
Her departure comes at a key moment for the once-obscure TWDB, which has gained significant publicity over the past year after lawmakers overhauled its structure during the 2013 legislative session. The agency is also responsible for administering $2 billion in loans for water projects that Texans approved in November's constitutional elections.
Williamson was appointed by Perry along with Bech Bruun, formerly of Perry's appointments office, and Carlos Rubinstein, a former member of the Texas Commission on Environmental Quality. She is the widow of the late Ric Williamson, a former state legislator and close friend of Perry.
