Today we didn't get really gnarly rain, just off and on showers, but it doesn't matter. Van Nuys Blvd. between Parthenia and Nordhoff becomes a mighty river when it rains.

I'm going to start pushing for something to be done about this. It's been problematic ever since I started living at my apartment (1989) and nobody's done anything concrete about it. If Sun Valley can get a storm drain makeover, why can't Panorama City?
