Having trouble finding the reason on google, so I’m enlisting help, does anyone

Having trouble finding the reason on google, so I’m enlisting help, does anyone know why the city would have dumped loose gravel on Lillian crescent and seemingly oil as well? Nearest I can find is some method of road repair from the 50’s involving gravel and tar.

If it was road repair, it’s strange since Lillian is nowhere near as bad as other roads in the city.

Edit: they need to do it to John st. Also, I find it amusing they left the potholes untouched.
