 Facilities such as a sawmill, a gristmill, and a store soon brought more people to the area.A mail service was established, and after rejecting several names for the nascent town (including naming it in honor of then-President Millard Fillmore), residents suggested the name "Plano" (from the Spanish word for "flat"), as a reference to the local terrain, unvaried and devoid of any trees.The name was accepted by the post office.
