Needing 9,702 valid signatures to qualify for the June ballot, the sponsors of the proposed Waterfront Height Limit Right to Vote Act delivered over 21,000 raw signatures to the Department of Elections this afternoon.

Designed to prohibit the increasing of existing building height limits for parcels along San Francisco’s waterfront, such as for the Warriors’ proposed arena project, the measure would require voters to approve the upzoning of waterfront parcels on a project-by-project basis.
