Anything to be done about parking hogs?

This is a really petty rant, but:

In front of my building there is enough space for two cars, bounded by a driveway on one side and a fire hydrant on the other. For the last few months, these spots have been dominated by one man who owns two SUVs. When he's driving one, he moves the other to the exact middle of the spot, so that there's no way to park on either side without either blocking the driveway or sitting right up against the fire hydrant; then on his return, he pulls in front of the hydrant, backs up his other SUV into the back spot, and then pulls the one he's been driving into the front spot.

This arrangement has allowed him to hold these spots for all but maybe four weeks out of the last six months or so; whatever his work status (he looks too young to be retired, but this is PS so who knows), he's always around on Monday to move his cars away for street cleaning and then move right back as soon as the sweeper has come through. To make matters worse, he gets back late every night (well past 11 usually), with his stereo blaring, and takes five minutes adjusting his two cars, one of which has an incredibly loud jingle that plays when it's backing up, ten feet from my bed.

Is there anything I can do about this, or is this just an example of the sort of jerk you have to live with if you choose to live in the city? Parking spots in PS aren't the easiest thing to come by, and it really gets on my nerves that someone can be this selfish and take spots away from everyone else (myself included).
