Grants for flood control maintenance shall be so employed that as far as possible, funds will be on hand to meet unusual, unforeseeable and emergent flood conditions. Allocations by the department of ecology, for emergency purposes, shall in each instance be in amounts which together with funds provided by local authority, if any, under reasonable exercise of its emergency powers, shall be adequate for the preservation of life and property, and with due regard to similar needs elsewhere in the state.
