Does severance delay my unemployment claim? after 16 years as a production planner

I was offered severance of 16 weeks after being let go as a production planner and I am unsure how it affects benefits. I have read a lot of threads here and could not find my exact situation. I have a mortgage and need to plan.

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