Va. Code § 15.2-2628
In anticipation of the issuance of bonds under the provisions of this chapter and of the receipt of the proceeds from the sale of bonds, any locality may borrow money and issue its notes for any purpose for which bonds of the locality have been authorized in a principal amount not to exceed the principal amount of the authorized bonds. The notes shall mature and be paid within five years of the date of their original issuance. Any notes may be extended or refinanced from time to time, provided that no extension or refinancing matures later than five years from the date of the original issuance of the notes.
The locality may, in its discretion, retire any notes by means of current revenues, special assessments, or other funds, in lieu of retiring them by the issuance of bonds, provided that the maximum amount of bonds that has been authorized must be reduced by the amount of the notes retired in such manner.
