City of Rio Vista
Rio Vista City Council
This person would hold one of two at-large seats on Rio Vista's City Council. The Council has five members total, and a City Manager runs day-to-day operations. Rio Vista's Mayor is not directly elected. Instead, the Council picks a Mayor and Vice Mayor from among its own members. This makes the Council race Rio Vista's only citywide vote for city government.
Four candidates are running for two at large seats on Rio Vista's City Council. Incumbent Rick Dolk faces three challengers. They are Robert Butler, Gloria J. Thibeaux, and Leslie Codling-Dichet. Voters may choose up to two. There is no primary.
Council seats are elected at-large and citywide. Rio Vista's Mayor and Vice Mayor are not directly elected -- the Council appoints its own Mayor and Vice Mayor from among its elected members, confirmed by the city's own site: sitting Mayor Ronald Kott was elected to the Council in 2014, appointed Vice Mayor in 2016, and appointed Mayor in 2017. So this Council race is the only citywide vote on this ballot for Rio Vista city government. Winners join the rest of Rio Vista's 5-member Council -- the city budget, land use and zoning, and oversight of city staff for this Solano County city of 10,005 residents (2020 Census) on the Sacramento-San Joaquin Delta -- while a City Manager runs day-to-day operations. The county's own ballot does not specify an exact number of years for the term, and no Rio Vista resolution or notice confirming one was reachable this session.
Fellow incumbent Lisa Duke did not file for re-election, so one of the two seats is effectively open alongside Dolk's bid for another term; Butler, Thibeaux, and Codling-Dichet are all first-time candidates for Rio Vista city office. All four candidates filed an official ballot statement with the county, giving this dataset a genuine, symmetric first-person record for each of them.
