Hazard 

The masonry parapet collapses onto the street canopy, which fails and falls onto the footpath along with parts of parapet.

Potential structural strengthening project

Fit a structural steel frame (portal frame) under the canopy, with legs supported on the footpath. The frame supports the canopy under the weight of falling masonry.

Possible first steps with a structural engineer

They assess the structural capacity of the canopy and provide specifications for the steel frame.
