If the county identifies a relocation site that meets the terms of the lease equal to or better than the present site, and if FIU raises more than the $230 million that relocation will cost (plus the cost of land) there would be a three-year notice to move. However any possible move is, at the very least, years away.
If the county finds an alternative relocation spot that meets or exceeds the lease requirements and FIU can raise over $230 million for the relocation (plus land expenses), they will receive a three-year notice to relocate. Nevertheless, any possible move remains several years in the future.
