The event will take place at the plaza in the 361-371 block of California Avenue (in front of Starbucks) and will feature visual displays of the completed project.
The public is invited.
A timeline of the construction phases is nearly complete and will be available soon, according to a city press release.
The scope of the project includes beautifying the streetscape with wider sidewalks and other amenities, as well as replacement of the water main from El Camino to the Caltrain station.
The project is expected to be complete by the end of the year.
