What is the test for establishing a "quiet place where yards are wide, people few and motor vehicles restricted"?

"A quiet place where yards are wide, people few, and motor vehicles restricted are legitimate guidelines in a land-use project addressed to family needs. This goal is a permissible one within Berman v. Parker (348 U.S. 26, 75 S.Ct. 98, 102, 99 L.Ed. 27). The police power is not confined to elimination of filth, stench, and unhealthy places. It is ample to lay out zones where family values, youth values, and the blessings of quiet seclusion and clean air make the area a sanctuary for people."
