(a) The agreement is in writing.
(b) The writing is signed by the chair of the board of supervisors.
(c) A copy of the writing is certified by and filed with the clerk of the board of supervisors.
All of these writings and copies are public documents.
If a county purchases, hires, or rents any apparatus specified herein pursuant to a local purchasing ordinance, including competitive bidding procedures, it does not have to comply with subdivisions (a), (b), and (c) herein to create a charge against the county.
