When following the nav off the 210 freeway to this charger, it directed me south on Marengo, right on Colorado, left on Arroyo, then it suggested a seemingly illegal left turn across a double-yellow line island into the Arroyo entrance.
Perhaps a safer way to enter is to continue south on Marengo past the parking structure, turn right on Del Mar, then right again on Arroyo. Then you can enter the structure with a right turn.
