Cal. SHC § 5896.10

If the work or improvement consists solely of a conversion, and the work or improvement is performed by a public utility, cable operator, or public agency, the resolution of intention shall provide that (a) the warrant, assessment, and diagram or (b) any bonds issued or to be issued to represent unpaid assessments, or both (a) and (b), shall be sold as the legislative body directs. The purchaser, and any successors, shall have the same rights and liens as the contractor to collect and enforce the assessments and all bonds issued to represent unpaid assessments. If the work and improvement consists, in part, of a conversion and, in part, of other types of work or improvement under this division, the legislative body may provide, in the resolution of intention, that the costs and expenses of conversion are part of the incidental expenses to be advanced to the city by the contractor and to be included in the assessment. Any payments made upon assessments, any proceeds from the sale of the warrant, assessment, and diagram or bonds, and any incidental expenses so advanced to the city may be used by the city for the purpose of making payments to a public utility, cable operator, or public agency pursuant to an agreement made under Section 5896.9.
