BERKELEY — Berkeley voters will be asked in November to approve a $135 million affordable housing bond.

If passed — the measure needs a two-thirds majority — Berkeley property owners would be taxed an additional $23.27 per $100,000 of assessed value each year, according to a city staff report presented at a City Council meeting where the measure was unanimously approved. With the city’s mean assessed home value of $425,000, the average homeowner would pay about $97 a year during the bond’s 36-year period, the report said.

Mayor Jesse Arreguin, at the July 10 council meeting, said the bond, if passed, could help the city maintain what makes it so great: its diversity

“That diversity is threatened due to rising housing costs, home prices, and displacement,” Arreguin said. “It’s critical that we as a community do what we can to increase resources to create housing opportunities for our homeless, our working families, our teachers and our middle class, so that this can truly be a diverse and inclusive community.”

The city would use the bond money to acquire, improve, preserve or built affordable housing for people and families whose incomes range from “extremely low” — 30 percent of the area median income, or $34,850 for a family of four, according to the city’s website— to “workforce” — between 60 and 120 percent, of the area median income, which is $69,720 to $139,440 for a family of four. It would also assist vulnerable populations, including veterans, seniors, local artists, the disabled, current or former foster youth, abuse victims, homeless people, and people suffering from mental health or substance abuse illnesses, the report said.

“There’s a critical need for affordable housing for all those housing types,” Arreguin said.

The city would also be able to give money to third parties such as nonprofit developers for affordable housing projects. The $86 million affordable housing project on Berkeley Way and Henry Street could use funding from the bond, as well as housing projects for Berkeley Unified teachers.

If voters pass the measure, an independent citizen oversight committee would be established to oversee spending; the bond would undergo an annual independent audit.
