Documented ties

Each item below is a documented connection, not evidence of impropriety. Contributions disclosed on the record and votes cast are public facts; this site draws no conclusions from them.

ConnectionVendorContractsEvidenceSources
West Coast Arborists: $1,690,900 award (Jul 28, 2026) - Sanchez the only No; indirect labor-union overlap
The unions are not the vendor; the overlap rests on a self-reported labor affiliation and is circumstantial. WCA's own officers (Mahoney family, Epperson) were not found in any donor filing reviewed. This is a documented connection, not evidence of impropriety.
