Section 10.11. Statement to taxpayers.
   Upon receipt of the city tax roll, the treasurer shall proceed to collect the taxes.  He shall prepare and mail to each taxpayer, at his last known address on the tax roll, a statement or billing showing the description of the property, the assessed or equalized valuation, and the tax payable, but the failure to send or receive such statement shall not prejudice the validity of the tax or the right and duty to collect or enforce payment thereof.
