City officials have a 10-year plan to battle homelessness at a cost of nearly $2 billion. “As we continue working on regional solutions with state and county officials, we must seize this moment and we’ll need everyone’s help,” the mayor said. Property owners would pay an extra $40 to $80 a year in taxes, according to city estimates. An other possibility to raise money could be to create a parcel tax on property improvements that could raise around $90 million a year over 10 years. Another city, another solution: in San Francisco several city supervisors are trying to place a measure on the November ballot that would create a 1.5 percent payroll tax on technology companies to pay for homeless and housing services.
