05.050 REVIEW OF ANNEXED LAND FOR SOLID WASTE FACILITY SITING

Within a one-year period following annexation of land into the City, the City will determine whether or not the annexed land, where the land is designated for commercial and industrial use, includes appropriate areas for siting solid waste facilities. If commercial or industrial designated land is annexed to the City that is appropriate for siting solid waste facilities, the City will then notify Metro of the need to update this agreement.
