but @pooriggy, what am i suppose to do with this hill?
You are supposed to plant something that offers screening from the houses behind you, offers some vertical scale and interest to the landscape. Wild flowers are nice, however they only grow 2-3' tall. This link to an Ag Extension in your area provides some ideas for evergreen screening. I'm a fan of the Nellie Stevens Holly, its native look is an improved variety for your location. https://chatham.ces.ncsu.edu/2016/10/what-is-the-best-evergreen-for-screening/
Also, use mulch as a ground cover to keep weeds down. Pine needles are not dense enough to cover soil and keep weeds down. Once an evergreen screening is established you could put perennials to fill area and help keep weeds out.
