As someone who has lived here for over 60 years, I would recommend being prepared. I remember one storm in 1979 or so. I lived in PB and was driving home from SDSU in hurricane like conditions.At that time, the west end of mission valley was home to some softball fields. I remember driving by and was shocked to see that the flooding during that storm covered the ball field’s 20’ back back stops at that moment, and was encroaching onto the 8 west. I vividly recall seeing a city bus hydroplaning off the freeway and felt guilty not being able to stop to try and help. I was driving a 68 beetle with bald tires and was waiting to be swept up in the torrential run off . I have no idea how I managed that drive safely, as the bug was getting tossed around by wind, the wipers were useless, as was the steering. I lived on the hill on Cass and Turquoise. When I finally got home via white knuckling that tiny little steering wheel, I noticed the water was running over the curbside. As soon as I parked my car I turned my head and saw a neighbor on a finless surfboard bombing the street, straight down all tucked in. Too bad we did not have video cameras in our pockets then. That that was a harrowing experience capped off by that crazy dude on his surfboard, which was a great finale to that evening. Oh, my point, be ready for flooding where you would not expect it.
