The Police Protective League stated its intention to allocate several million dollars towards advertising and mailers to campaign against Measure FD. Union leadership expressed concerns about the tax being permanent, with no specified end date, citing affordability issues for residents.

Firefighters' union president Doug Coates argued that opposing the measure puts the public at risk, particularly in vulnerable communities, and called it a critical public safety decision for the city.

The firefighters' union has already invested over $2 million in supporting Measure FD and is seeking authorization from its members for an additional $3 million in spending. Internal polling suggests the measure has majority support, but the union acknowledges the need for a strong response to opposition.

If approved, Measure FD would increase the city's sales tax to 10.75%, costing the average person an estimated $86 annually. The initiative also mandates continued funding for the Fire Department at a specific average percentage of the general fund. Proponents estimate the tax could enable the construction of at least 30 new fire stations and the hiring of approximately 1,400 new personnel by 2050.
