Assuming the City moves to district elections and set the districts in 2018, what districts will be open in the next election in 2020? For example, if the Mayor and two Councilmembers are up for reelection in 2020, will it be the districts the two incumbents are in that get to vote? What if there is another district with no Councilmembers currently living there? If the Mayor runs for re-election and he lives in a district that has no Councilmember, is that district Councilmember seat up for election as well?

No. The seats just rotate in. Each current member of the Council serves out the rest of the term to which he or she was elected, and then must run for re-election in the districts. It potentially gets a little more complicated if two councilmembers are paired in a single district, but everybody still serves out his or her full current term. As part of the establishment of City electoral districts, the Council will determine the districts that will have an open seat at the 2020 election.

The City Council will be determining the sequence of elections as part of the process of establishing the voting districts.
