Please use the P.O. box on this website and on your paper registration forms. There is no staff at the Civic Park building. All mail is going to City Hall. Several buildings are in the same boat and the mail is going into a big pile to be sorted by whatever employee is available. If you sent your mail to the civic park address or haven't heard from us in two weeks, consider your mail lost. If you have relatives who are registering for the senior club only, use the Walnut Creek Senior Club site to register.
