Former NBA big man Bill Walton proposed building a town to house the homeless population in San Diego, California.

Walton and business owner George Mullen, San Diego natives, co-authored a Times of San Diego opinion column in which they promoted a grassroots effort to build a site called Sunbreak Ranch.

“Most of us can no longer walk or bicycle our downtown city streets, sidewalks, and parks without facing an obstacle course of tents, bodies, human excrement, needles, trash, and a slew of walking-zombies who are impossible to distinguish between those just down on their luck and others who are out-of-control substance abusers about to attack us,” Walton and Mullen wrote in a column published Sunday.

“In San Diego, we have had enough. We are no longer going to follow other once-great American cities into the abyss of homelessness, lawlessness, and roadside shantytowns.”
