Existing law authorizes 2 or more public agencies, as defined, to enter into an agreement to exercise common powers. Existing law also permits certain federally recognized Indian tribes to enter into joint powers agreements with particular parties and for limited purposes. This bill would include a federally recognized Indian tribe as a public agency that may enter into a joint powers agreement. This bill would also make conforming changes by repealing now redundant conforming related code sections. This bill would also prohibit any joint powers authority that includes a federally recognized Indian tribe from authorizing or issuing bonds pursuant to the Marks-Roos Local Bond Pooling Act of 1985 unless the public improvements to be funded by the bonds will be owned and maintained by the authority or one or more of its public agency members, and the revenue streams pledged to repay the bonds derive from the authority or one or more of its public agency members.
