Honolulu Authority for Rapid Transportation board member Robert “Bobby” Bunda is stepping down to spend time with his family, according to an agency press release.

Bunda, a former state legislator, has been on the HART board of directors since September 2011, and was appointed to a five-year term in 2013.

The board, which oversees the city’s $6 billion rail project, will begin searching for a replacement in July when it puts out a call for nominations from the public. Bunda’s last day is June 30.

Here’s what Bunda had to say in a written statement:

“The experience I have gained as a member of the HART board has given me a deep sense of appreciation for my colleagues on the board and for the entire HART team, all of whom work hard each day to make the project successful. The one thing we never get back is time. For that reason, I have chosen to spend more time with my family.”

Robert Bunda’s last day on the HART board of directors will be June 30.
