There's a 'small' problem, Heather. It's a good idea, but making those 2 things available makes the city liable for anything that goes wrong there , no matter what, such as someone getting their hand hurt in the locker door. Or someone slips in the shower and hurts their back. Then they sue. Then the ACLU gets involved, and the cry goes up that the person did not have a personal nanny to make sure they didn't slip, or proper instruction in 3 languages about how to operate the storage locker door. So-called 'activists' descend, the 'poor, helpless, homeless (minus the whisky bottle)' are trotted out for the camera, the threats mount, the judge caves, the city loses millions, and everyone who works in the city gets to pay special fees/higher taxes to pay for the lawsuit, after which the lockers/showers are bulldozed so as to prevent another lawsuit, and all the money used to construct them is wasted.

If you can force the ACLU into promising not to touch ANYTHING involved, it might work.
