Va. Code § 15.2-5004
The allocation formulas prescribed in this chapter are established to utilize the entire state ceiling on private activity bonds by providing issuing authority to housing and industrial development projects. The allocation to local housing authorities and the allocation for industrial development provided in § 15.2-5002 shall be effective for such period in each calendar year as is set forth in the guidelines established pursuant to § 15.2-5003.
Any unused bond authority remaining in any category after the effective period of the allocation set forth in such guidelines shall be reallocated to the Virginia Housing Development Authority (and any unused bond authority allocated to the Virginia Housing Development Authority shall continue to be allocated to the Virginia Housing Development Authority) in the amount requested by the Virginia Housing Development Authority, subject to the receipt by the Director of the Department of Housing and Community Development of assurances from the Virginia Housing Development Authority of anticipated usage of such amount of unused bond authority within the time period permitted by federal law, and any remaining amount that is not so reallocated (or continued to be allocated) to the Virginia Housing Development Authority shall be reallocated according to the guidelines established by the Board of the Department of Housing and Community Development and the Virginia Small Business Financing Authority. The guidelines shall also provide a priority system for the reallocation of any such remaining unused bond authority not reallocated (or continued to be allocated) to the Virginia Housing Development Authority at year-end to projects that are eligible to carry forward issuing authority to later years. The provisions of this section shall not apply to the amount of the state ceiling set aside for the state allocation during any calendar year.
