The total aggregate amount of these notes outstanding at any one time shall further not exceed the sum of five hundred thousand dollars ($500,000). (b) Any note proposed to be issued pursuant to subdivision (a) with a term longer than five years shall not be issued until after a public hearing is conducted with respect to the issuance and a resolution is adopted approving the issuance. At least 15 days prior to the public hearing, the board shall cause notice of the hearing to be published pursuant to Section 6061 of the Government Code in a newspaper published in the principal county.
