Thunderbird Landing now accepts two forms of Online Payment: eCheck and Credit Card. An eCheck is a payment drawn directly from your checking or savings account with no associated fees. By clicking on one of the Pay Online links below you will be transfered from the Thunderbird Landing website to a secure website provided through Zions Bank where you can select whether you would like to pay using your checking or savings account (eCheck) or with a credit card. (you may pay online via eCheck regardless of where you bank). Please note that all credit/debit card payments may be assessed up to an additional 3% processing fee.
