California Code, Streets and Highways Code - SHC § 5898.31

Since contractual assessments on real property under this chapter are voluntary and imposed pursuant to an agreement with an assessed property owner, the Legislature finds and declares that voluntary contractual assessments under this chapter are not assessments for the purposes of Articles XIII C and XIII D of the California Constitution and therefore the provisions of Articles XIII C and XIII D and Article 4.6 (commencing with Section 53750) of Chapter 4 of Part 1 of Division 2 of Title 5 of the Government Code are not applicable to voluntary contractual assessments levied pursuant to this chapter.
