The Legislative Assembly finds that the construction of a facility may have substantial economic impact upon units of local government obligated to furnish services, buildings or other resources in the area in which the facility is being constructed. The Legislative Assembly further finds that this impact may occur in advance of the time when sufficient real market value occasioned by construction of the facility is added to the assessment and tax roll to bear the facility’s portion of the costs of the governmental services, buildings or other resources that the facility’s construction necessitates. The purposes of ORS § 311.850 to 311.870 is to provide a method for prepaying ad valorem property taxes during the period of planning and construction of the facility, in order that units of local government may provide the services, buildings or other resources necessitated without imposing an undue burden upon other properties subject to taxation within the unit, and to provide for repayment of the amounts prepaid.
