"We cannot look away from this and we can no longer accept the status quo if we truly believe that Black lives matter," Council President Lorena Gonzalez said.
It was also reported that the new bill would also dismiss as many as 100 officers from different police units and limit staff pay to $150,000.
The council said the bill was a "downpayment" toward a bigger goal to eventually defund the department by 50%, which would likely happen next year.
Council members Debora Juarez and Alex Pedersen cast the opposing votes, Seattle's KING-TV reported.
The council had approved the cuts by 7-1 in August. The move has led police Chief Carmen Best to retire, effective Sept. 2, claiming the planned cuts had placed her in a "position destined to fail."
Best, the city's first Black police chief, had been with the department for nearly three decades.
The mayor’s veto was overridden by the council on three bills, that also includes the transference of $14 million to community safety programs.
It was also reported that if the veto override had failed, Gonzalez had planned an alternate budget offer that would limit cuts to the department and cut proposed community funding.
During an hour of public comments most speakers urged the council to override the veto in solidarity with Black Lives Matter, The Times reported.
“Everyone deserves to feel safe … Countless videos of Black and brown lives lost here in Seattle and across the country shows us that not everyone feels safe,” González added, “We need public safety that’s centered on harm reduction, not the status quo...When I look back in this moment of time, I want to be able to tell my daughter, who I’m currently holding in my arms, that I did the right thing and that I voted on the right side of history.”
The mayor, at the request of the Seattle Police Officers Guild, business leaders and some residents, has called for the council to postpone the defunding of the department.
The city also suffers from financial issues because of the coronavirus pandemic.
Durkan is set to reveal her budget plan next week.
Both Durkan and Councilmember Kshama Sawant are facing past incidents – Durkan over the police department’s use of force during protests and Sawant for allowing protesters inside City Hall during the pandemic.
