Cotati's hexagonal town plan, one of only two in the United States, was designed during the 1890s by Newton Smyth as an alternative to traditional grid land planning. The six-sided town plaza was designed for founder Thomas Page, and each of the surrounding streets was named after one of Page's sons. "Cotati" derives from "Kotati", a local Pomo Indian chieftan [sic].
