Need to drain supply line

Every year my backflow preventer freezes. I drain it each year, but it still freezes. This year the supply valve froze on the intake side. Is there a way I can put a valve under ground on the supply side in order to drain the line each year and keep the water from building up behind the shutoff valve?
