Someone must have driven into the fancy corner sign (Fairplex Drive and Avalon Avenue) marking the start of the Valwood Estates subdivision in Pomona, based on the damage. A piece of plywood covers the hole.
The tract has had its ups and downs — in 2005, the Post Office briefly stopped delivering there after a shooting, leading to protests — but the architects, Palmer & Krisel, evidently have a following: Someone on Flickr has posted the original sales brochure, and a website that tracks Krisel homes on the market has posted about the neighborhood multiple times the past few years, including this overview, which begins:
“Consisting of just over 500 Palmer & Krisel-designed homes built in 1955 by builders Weber-Burns, Valwood Estates offers relatively affordable modernism in western Pomona.”
