The 1991 election marked the fourth straight in which a new mayor was elected. Incumbent Council Member Robert Barnstone opted to run for mayor instead of reelection and narrowly lost in a runoff with former Travis County Commissioner Bruce Todd.
Incumbent Council Member Charles Urdy easily won reelection.
Competing for two open council positions, Ronney Reynolds and former Austin school board trustee Gus Garcia both won their runoffs.
Seven propositions were on the same election ballot. Propositions 3 through 7 proposed City Charter changes that, if approved by voters, would have mandated dedicated sources of funding for environmental measures, including energy efficiency, renewable energy, water conservation, recycling, and environmental protection. These propositions drew voter approval ranging from 42 percent to 48 percent, but none passed.
