Austin City Manager Spencer Cronk has hired two more assistant city managers to his executive team to oversee the city’s public safety and mobility efforts, the city announced Tuesday.

Assistant City Manager Rey Arellano will stick with his current role to oversee public safety—which includes police, fire, EMS, city code compliance, homeland security, municipal court and watershed protection.

For mobility operations, Cronk has brought in Gina Fiandaca, who will leave her current role as commissioner of Boston’s transportation department. As commissioner, Fiandaca helped the department release Go Boston 2030, a 15-year, $4.7 billion transportation plan, the first such plan for Boston in decades.

Arellano and Fiandaca represent the final choices for Cronk from a field of 10 candidates.

"Gina and Rey are going to be instrumental in helping us meet our goals in the areas of safety and mobility, which have been identified as key strategic priorities for the City," Cronk said in a statement. “They will be leading multi-talented teams working to tackle some of the top challenges facing Austin."

Cronk’s executive team now has four of five pieces assembled, with the earlier hires of Rodney Gonzales to oversee economic opportunity and affordability and Christopher Shorter to head the city’s efforts in health, environment, culture and lifelong learning. Last year, Cronk said he would hire an all-new executive team to match the goals laid out by the city's Strategic Direction 2023 plan, and that existing assistant city managers, such as Arellano, would need to apply and compete for the position.

The final hire for the position of Cronk’s deputy city manager is still ongoing.
