• Directs Legislature to allow repair or replacement of environmentally contaminated property or structures, as defined, without increasing the tax valuation of the original or replacement property.
• For tax purposes, property value is the assessed valuation for 1975-76 unless the property is reappraised upon purchase, new construction, or change in ownership. For property rendered unusable by environmental contamination, this measure allows either: transfer of the base-year valuation to a replacement property if the contaminated property is transferred; or exclusion of repair or replacement of damaged structures from the definition of "new construction."
