Incumbent Antonio Medrano and retired school principal Randall Enos have requested the nomination papers that are required to file for the Nov. 6 election. The seats occupied by Medrano and Tony Thurmond expire this year. Thurmond had not taken out papers as of Friday afternoon.
Incumbents and challengers have until Aug. 10 to return a filing fee and valid signatures of supporters to qualify for the ballot. If at least one incumbent does not file by then, the deadline for challengers to file will be extended to Aug. 17.
The four-year terms of seats on the five-member board are staggered by election year.
