The Todd Road Jail in Santa Paula is surrounded by open space and agriculture.
Sheriff Geoff Dean is moving forward with a plan to apply for a grant to help pay for jail expansion plans.

The expansions plan includes a medical unit and more than 60 beds.
Overcrowding has been a problem at jails in the wake of the state's realignment plan.
Realignment led to longer sentences served in county jails.
