@avirr@sfba.social The gorge is 100 feet deep and (unfortunately) the river is fairly dammed, so flooding isn’t a major concern in that stretch. But yeah, keeping the river gorge does control the potential damage! There’s one stretch called Bohemian Flats where people lived in a not-quite-authorized place in the gorge that was at flood risk. The main flood risk around here is from torrential thunderstorms, and the city storm drain system is…substantial.
