San Diego voters will decide in November on a proposal by the Chargers to raise local hotel taxes for a downtown stadium and convention facility.
City Clerk Liz Maland says the football team had secured enough valid signatures to qualify the measure for the 2016 ballot.
If approved, the proposal could keep the team from moving to the Los Angeles area, where it has been approved by NFL ownership to join the Rams in a new stadium being built in Inglewood.
