The department shall devise and administer a noncompetitive program of grants to eligible entities within each county area for planning and development for new parks and recreation facilities or renovations of existing facilities. Grant funds may not be used to supplant existing funding for parks and recreation purposes nor may they be used to retire indebtedness incurred prior to July 1, 1988. Grant awards must be made by the department according to criteria and administrative guidelines it shall develop and furnish to potential grant applicants. All grants must be in the form of reimbursements and no grant may be awarded unless the grantee matches the grant in an amount equal to at least twenty percent of the grant. All grant applications must be submitted in writing and signed by a majority of the members of the legislative delegation representing the eligible entity applying for the grant. Unexpended grant funds in any account may be carried forward for not more than three succeeding fiscal years, after which any unexpended funds must be reallocated on a statewide basis in the next fiscal year as part of the distribution to the Fund for that year.
