Fraktur in Westminster, CA

I had reason to visit Westminster, California earlier this month (can't wait to share why - a clue: a saw, a saint, an exercise ball) and was totally perplexed by the street signs that are in some Fraktur-esque font. Why? Does anyone know? I emailed the city for an explanation. I can't tell you how much "Trask" looked like "Trash" street. Tips appreciated.
