County supervisors are asking staffers to tally all of the funds spent on homelessness by Los Angeles County, ahead of a vote next month looking at funding programs and outreach.

Measure H, which voters get a chance to weigh in on next month during a special election, asks if voters would support a half-cent sales tax to pay for homeless services.

The March 7 special election will ask voters if they will pay a 0.25 cent sales tax for 10 years in order to pay for programs to fight homelessness.

Supervisor Kathryn Barger authored a motion Tuesday asking the county to track all of the current resources being spent to fight homelessness.

The reasoning given was that in order to make sure the services are not duplicated, and in recognition that the tax increase is meant to supplement, not supplant, existing funds to fight homelessness.

Barger initially opposed the measure, according to Tony Bell, spokesman for Barger, but supported it after several major revisions. The bill changed from parcel tax to a sales tax, and originally lacked a sunset date. The current measure as proposed would expire in 10 years.

Additionally, the measure now restricts spending to specific anti-homeless programs identified by the Los Angeles County Homeless Initiative.
