After the flood water was pumped out, I, the store owner, and several of our regular customers helped salvage what we could. I remember we drove a car into the mall to provide light in the soggy store as we went through the muck and recovered some of the stuff (not much, but some). The south end of the mall was rebuilt and we moved in to a new location, but the mall never really recovered. The anchor stores, which had been losing money anyway, choose to forfeit the rest of their leases rather than come back. Those of us who did return never made much money.
The hotel in which Lisa and I stayed before visiting my mother is just down the street from the site of what is now optimistically called the Feather River Center. On our way out on Sunday morning, we drove by the old mall.

This is the entrance through which I normally entered the mall on my way to the original store site. Most of the mall is now completely boarded up, although the south end (which was originally a K-Mart and still has some directional signs recognizably in the K-Mart 1970s style) has been rebuilt into a FoodMaxx warehouse grocery store. Otherwise, the entire complex appears derelict.
I was surprised that a Wal-Mart was built across the road from the mall on what had been as I recall greenfield property. Given the hopeless state of the mall, it seems to me it would have been more sensible to simply tear down the mall and build the Wal-Mart there. Presumably there's a story there about which I know nothing. The entire area is below the level of the river, so I don't think that has anything to do with it. (The bed of the river is above the land around this area, which is a legacy of the gold rush hydraulic mining washing so much debris downriver. Without the high levees, the entire Marysville-Yuba City area would be under water.)
I spent five important years in that mall and it was a significant part of my life, but some things are gone and will never come back.
