What strategies could a land owner, threatened with eminent domain use to represent themselves in court to increase compensation?

Hello, My family owns a 2 family home in Carteret, NJ and the Carteret Redevelopment Agency is threatening us with eminent domain. The block is considered blighted because of an unoccupied veterinarian office and bar behind our home on the other side of the lot. They have already made redevelopment plans for the block and is undervaluing our home. We cannot find another 2 family home in the area for the compensation considered "fair market value". We are willing to move but we need at least enough compensation to acquire another income generating property. What strategies could a landowner use to represent themselves in court and increase the compensation that they've considered fair? Thank you.
