Responding to citizen complaints about polished glass shards in the new California Avenue sidewalks, Palo Alto is preparing to apply a concrete-patching solution to problematic patches next week.
The city announced Thursday that the contractors working on the ongoing streetscape project will be applying the patching solution to select portions of the sidewalk where glass shards are too conspicuous and potentially hazardous.
"There are some areas where the glass is not fully embedded in the concrete, and the concrete-patching solution will be spread over those areas to even out the gaps and provide a more consistent surface," the city's announcement stated. "Once dried, the glass will be securely fixed within the concrete."
The concrete patching will be applied to roughly a third of the glass-embedded sidewalk, though the city does not expect this to delay the completion of the renovation project, which is still set to conclude in late March.
The $6.9 million project includes widening of sidewalks, a creation of two new public plazas, new street furniture, including newspaper racks and benches, and a reduction of driving lanes from four to two.
According to the city's announcement, the concrete material has been tested and passed a slip-test inspection. The material has been used by Caltrans and other agencies for similar purposes, the city's statement notes.
