The Salinas Fire Department Haz-mat team was brought in to assess the situation and clean up the scene. The hazardous substance spill happened on Friday morning.
The powder came from a barrel off a truck, and hazardous material reponders determined it was a highly caustic substance, officials said.
It was neutralized at the site and vacuumed up, a city spokeswoman said.
