Severance and unemployment, do they overlap? - 17 weeks in

I was offered severance of 16 weeks after being let go as a logistics coordinator and I am unsure how it affects benefits. It has been weighing on me all week. I also wonder about the job-search requirement. Who should I ask before signing?

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