Chipmunk burrows

We've seen chipmunks and their burrows in our front yard and we werewilling to ignore them till today. We just discovered a burrowentrance right up against the brick steps leading up to our frontdoor. This is an area where we just had a French drain installed tocorrect drainage problems, and it's covered with sand, so it's easy toburrow into. They may also be burrowing underneath the steps for all Iknow. We're worried their tunnels and burrows might weaken the groundand cause structural problems in our walkway or steps.We don't really want to eliminate the chipmunks, but we really need toprevent them from burrowing in this particular area. I tried puttingsome stones over the burrow entrance, but they've already moved thestones away. I was thinking of putting mothballs into the tunnel, orpouring ammonia down it in hopes that they'd move to another spot.Suggestions? I've thought of live trapping and relocating them, butthat would be a last resort. And we're in a suburban area, so shootingwould not be an option even if we did want to eliminate them (which wedon't).
