This number is cited to a source document, and its arithmetic re-adds to the dollar (it cross-foots, or it is counted inside a total that does).
The county’s main operating fund, paid mostly by property tax. The biggest offices inside it: the Sheriff (patrol + the jail) $252.9M, Transportation & Natural Resources $91.4M, Technology & Operations $83.0M, Health & Human Services $71.8M, Juvenile Probation $54.7M, the District Attorney $36.6M, and EMS $29.0M. The tree below groups spending by function, as the county’s own financial statement does; note the Sheriff’s budget spans both Corrections and Public Safety, so a single “policing” figure would overstate it.
