Downtown Redding lost a lot of parking Wednesday. The south end of the California Street parking structure will soon join the fate of the north end as a pile of gravel and dust. Fences went up Wednesday around the structure, which parked about 350 cars. Downtown Redding business are very concerned about how far potential customers will have to walk get to their doors. A free shuttle will be put in service in mid march to ferry people from distant parking places to the downtown retail cluster.
