New project: Soil remediation, Oakland backyard

It looks like the soil in my yard may be toxic–or just industrial–enough that weeds don’t grow. It’s so dusty and filled with little rocks and glass.  I’m thinking about experimenting with soil remediation techniques to improve it and make it less toxic before I plan and landscape.
Ideas:
Test the soil
Plant sunflowers, bonset, goldenrod, yarrow for the year and see if they can improve the soil–maybe make a path around them but plan some big beds of them–have no idea what it takes to grow any of these
