AGO 1972 NO. 16 >
(1) A sewer district may levy special assessments for local improvements against county-owned real property which is specially benefited by the improvements. (2) A county whose property has been placed on a sewer district's special assessment rolls is precluded from objecting to the inclusion of such property on the basis of an asserted lack of special benefit where it has failed to comply with the procedures set forth in chapter 56.20 RCW for raising this issue, notwithstanding its nonreceipt of actual notice of the contents of the assessment roll, where the notice required by RCW 56.20.040 was properly given by the district.
