There is created in the State Treasury the Disaster Relief and Resilience Reserve Fund, which shall be separate and distinct from the general fund and all other reserve funds. Funds appropriated to the fund only may be used to develop, implement, and maintain the Statewide Resilience Plan, and for disaster relief assistance, hazard mitigation, and infrastructure improvements as set forth in this article. Interest accrued by the fund must remain in the fund and unexpended funds must be retained and carried forward to be used for the same purposes.
