Mayor London Breed attacked the San Francisco Board of Supervisors’ vote on Tuesday turning down a new housing development in the SoMa neighborhood in the city.

A 495-unit apartment complex was the center of the development plan. It contains about a quarter of “affordable” units in line with the affordable housing mandates. The location of the proposal is at Stevenson and Sixth streets parking lot close to the Powell Street BART station, SFGATE reported.

The proposal, however, was rejected by several supervisors in another crisis called the “NIMBY vs. YIMBY” discussion over development.

The said issue has stirred among the country’s most expensive cities to rent and own housing property.

Among the supporters of the development are Supervisor Matt Haney of District 6; Supervisor Catherine Stefani of District 2; and Supervisor Ahsha Safai of District 11. They are just among the 11 current supervisors.

Haney’s area could have housed the development. The supervisor criticized his colleagues for turning down the project.

“Our city has a massively out of balance jobs/housing ratio,” he wrote on Twitter last Tuesday evening. “We’re approving & building office jobs but not housing. It’s entirely unsustainable.”

Haney also mentioned that the development could provide employment for those in the construction field, mentioning the “extensive neighborhood support” for the project’s construction.

SFGATE contacted Haney for comment but no immediate response was provided.

Also on Twitter, Mayor London Breed agreed and attacked the eight other Board of Supervisors members who rejected the development. She said their vote is an aspect of “anti-housing ideology”.

Furthermore, the mayor dismissed issues over renovation in the district as unclear, which include those created by Supervisor Dean Preston of District 5.

Stefani, meanwhile, tweeted after the vote: “We need to stop letting perfect be the enemy of the good.”
