City officials shot down a $550 million plan to lure an NBA team back to Seattle — and sports fans flung violent threats and sexist abuse at the five women who voted against the measure.

The City Council voted 5-4 along gender lines to reject the measure, which would have cost taxpayers $200 million, due to their concerns over the project’s promised benefits, reported the Seattle Post-Intelligencer.

Lisa Herbold, who voted against the proposal along with the rest of the council’s first female majority since 1994, said she feared the development would cost the region some of its industrial and maritime jobs.

Their decision is supported by 77 percent of registered voters, according to polls — but some opponents expressed themselves with ugly rhetoric that’s been renounced by the project’s would-be developer.

“While we may not agree with the Council’s vote, misogynistic insults, vile comments and threats are unacceptable and need to stop,” said developer Chris Hansen.

The five women have received a barrage of sexist and violent threats against them since Monday’s vote.

“You have made this world a worse place by whoring yourselves out to the highest bidder,” one man wrote via email. “Each of you should rot in hell for what you took from me yesterday.”

“I TRULY pray for nothing but horrible things for each of you moving forward,” said the man, who was identified as Lynwood attorney Jason Feldman. “As women I understand you spend a lot of your time trying to please others (mostly on your knees) but I can only hope that you each find ways to quickly and painfully end yourselves.”

The Seattle Times reported that Feldman is currently appealing a 2 1/2-year suspension by the state bar association for having sexual relations with a client.

The client had accused Feldman of sexual assault in 2013, but he was not charged.

A Seattle man has filed a new bar complaint against Feldman for his “abusive” email — which he sent to each of the City Council’s five women.

The women have not yet commented on the sexist insults, which included individual threats and attacks against all women.

“I think someone should smash Kshama Sawant’s head into a brick wall,” one Twitter user wrote, referring to one of the City Council members by name.

“So this is why Ann Coulter has said that women shouldn’t be allowed to vote,” another man said.

Hansen, the developer, has a memorandum of understanding with the city that lasts through 2017, so his plan to build an NBA arena is not yet entirely derailed.
