Does severance delay my unemployment claim? (Detroit)

I was offered severance of 15 weeks after being let go as an IT help-desk technician and I am unsure how it affects benefits. This is my first time dealing with any of this. I have a mortgage and need to plan. How did your state treat it?

Some states only count certain kinds of severance. A local workforce centre could tell me which.

Before signing, I asked a friend who is a lawyer to look at the agreement. It was a short conversation and worth it.
