Donations have poured in to support Measure K, a 20-year extension of the 10-year half-cent sales tax approved by San Mateo County voters in 2012.
Campaign finance reports on file with the county Elections Office show $785,000 in donations since the end of August.
The highest were $300,000 from the Seton Medical Center in Daly City, $200,000 from the Chan Zuckerberg Initiative -- a fund headed up by Facebook CEO Marc Zuckerberg and Priscilla Chan -- $60,000 from MidPen Housing Corp. in Foster City, $50,000 from Facebook in Menlo Park and $40,000 from Bridge Housing Corp. in San Francisco.
On the ballot, Measure K's spending priorities for its anticipated $85 million a year in tax revenues start with housing for "seniors, people with disabilities, veterans and families." Other priorities: enhancing public transit, combating human trafficking and addressing sea level rise.
County supervisors have positioned themselves as supporting Measure K as a reliable income stream to reassure lenders were the county to borrow money for affordable housing from the bond market.
But County Counsel John Beiers said in an email that while projects for "core county facilities" are common in the bond market, affordable housing may not be in the same category. It's a complex issue that requires consultation with the county's bond counsel and financial consultants, he said.
