Colo. Rev. Stat. § 25-29-123
Nothing in this article shall be construed as a restriction or limitation upon any other powers which the authority might otherwise have under any other law of this state, and this article is cumulative to any such powers. This article does and shall be construed to provide a complete, additional, and alternative method for the doing of the things authorized thereby and shall be regarded as supplemental and additional to powers conferred by other laws. However, the issuance of bonds, notes, and other obligations and refunding bonds under the provisions of this article need not comply with the requirements of any other state law applicable to the issuance of bonds, notes, and other obligations. No proceedings, notice, or approval shall be required for the issuance of any bonds, notes, or other obligations or any instrument as security therefor, except as is provided in this article.
