I agree that this is unlikely to start the slippery slope all the way down to plumbing permits. But it's pretty easy to imagine it putting a damper on other large-scale projects that will span administrations. Off the cuff I'd guess this is not what folks building reservoirs, power plants, transmission lines, rail, shipyards, etc want to see. What do you do? Get your permit and wait for a change of party and see if your permit poofs out of existence before breaking ground?
