CA Water Code Section 1055.4

After the time for review under Chapter 4 (commencing with Section 1120) has expired, the board may apply to the clerk of the appropriate court for a judgment to collect the administrative civil liability imposed in accordance with Section 1055. The application, which shall include a certified copy of the board action, constitutes a sufficient showing to warrant issuance of the judgment. The court clerk shall enter the judgment immediately in conformity with the application. The judgment so entered has the same force and effect as, and is subject to all the provisions of law relating to, a judgment in a civil action, and may be enforced in the same manner as any other judgment of the court in which it is entered.
