Sounds like getting some chemicals sprayed out there with a garden sprayer and then wait a couple weeks. Then cut down and bag that stuff.
Yes! Strong herbicide first. Use Crossbow Herbicide Weed & Brush Killer
Use it very carefully! Crossbow kills all plants, so certainly do NOT
use it on a windy/rainy day.

There are many plants that grow back from their roots after they are
cut down, stump ground, and burned. In my region, you'd think that
would be Kudzu, but actually Crepe Myrtles are a nightmare to kill.
After cutting down the tree/shrub, I drill a hole in the stump and pour
in a cap of Crossbow then cover it. Let that work it's way through
the entire root system for a couple weeks. Once every cell in that
Aliens movie "Xenomorph" pest is dead, then you can grind the stump
and dig up the roots. If you don't kill the roots before grinding the
stump and digging, then you'll have 500 little Crepe Myrtle plants
coming up from the roots.
I plan to eventually cement the backyard and then throw pavers on top.
I don't think pavers over concrete is a good approach, but maybe
things are done differently in NY city. I finished a big walkway/patio
project in my yard about a year ago. Here are options I looked at
before deciding on good quality pavers...
#1) Stamped and stained concrete: cheap but better looking than
plain concrete. Probably the best choice for a rental property.
#2) Concrete with an epoxy coating: crazy-expensive but looks
very cool.
#3) Concrete pavers over compacted gravel: middle ground cost-wise,
much nicer looking than any concrete, lasts 50+ years if installed
correctly which is longer than any other option, and the pavers drain
water into the ground.
