Cal. Ed. Code § 15100.5
Except as otherwise provided by law, the governing board of the Peralta Community College District may, when in its judgment it is advisable, order the county superintendent of schools to call an election to be conducted pursuant to this chapter and submit to the electors of the district the question of whether the proceeds of previously authorized but unissued bonds of the district may be used for a purpose or purposes in addition to the purposes for which the previously approved bonds were authorized by the electors.
The governing board may, by order entered into its minutes, call for an election to expand the purposes of prior authorized but unissued bonds either as a single proposition on the ballot or combined with the question of issuing new bonds of the district for any purpose or purposes permitted by law.
If two-thirds of the votes cast on the question of expanding the purposes for which the proceeds of previously authorized but unissued bonds of the district may be used, or the combined question of expanding the purposes for which the proceeds of previously authorized but unissued bonds of the district and issuing newly authorized bonds of the district, are in favor of the proposition, the district may use the proceeds of the previously authorized but unissued bonds for the expanded purposes and may issue newly authorized bonds, as the case may be.
