The crosswalk at Alcatraz and Herzog is VERY unsafe. There are two elementary schools and a new Oakland Recreation Youth Center in the area. In addition, there is a large apartment building nearby with a large senior population. Cars are coming from four directions. There have been several recent near misses where children and adults were nearly hit. Many cars also drive at unsafe speeds. School crossing guards have expressed concern for their own safety. Something urgently needs to be done now. In my opinion, there at least needs to be flashing "Slow Children" street signs from multiple directions and a raised crosswalk with flashing lights when pedestrians are crossing. Thank you for your attention to this serious safety issue.
