Work is moving quickly at 70 Irwin; this week the City’s contractor Valentine Corporation started installing MSE block walls at the bottom of the hillside that was also the scene of a landslide during the winter of 2017. Installation of these two block walls marks the beginning of the long-awaited hillside restoration.
