Let's not get too far ahead of ourselves here. The WINS towers are still standing. It's likely that the tower bases are underwater, and it's possible (but not confirmed) that the elevated transmitter building took on water as well. 1010 may be off the air for a matter of days, but it won't be weeks or months.
Good point.
Here's some anecdotal experience from cleaning up after one particularly bad Puerto Rico hurricane where water came into the building and flooded the transmitter and the phaser.
First, you wait till the high water subsides. If area is severely damaged, get civil authoritiy to grant permit to access site. Once you get there: Make sure breakers are tripped. Same for geny set if it is inundated. Notify FAA if tower is unlit due to power outage / flooding.
If you have water pressure, hose everything off. If you don't, you have to hire a water truck and pump to clean. Check transmission line if air or gas filled for integrity, humidity. If problems, start dehumidifying or fixing.
Using filtered or, better, distilled water, spray out phaser and put high volume fans on it.
With more care, spray out the transmitter parts that were flooded. The damage is from dirt, debris, salt and minerals. Dry with fans, even hair blowers on low setting.
Check all electrical. Get a generator mechanic if you are not a engine type of engineer, and check the geny. If it is dry and clean and the fuel is not contaminated, make sure its not online and turn it over. Run for a while and see if it is "clean" as you may not have power company service for days (in my case, 8 days).
Wait. Keep fans running 12-18 hours and if you have AC, and you can power it off the generator, run it to dehumidify. Check tower bases for dirt on base insulators or isocouplers if an AM. Check line pressure if FM using air dielectric. If you can power tower lights with generator, get them going and inspect.
After that, inspect transmitter and phaser for any pooling of water, dampness, signs of arcing prior to going down in the floods. Depending on whether AM or FM, solid or hollow state, you may be able to power up the exciter or IPA stage. If that step works, power up.
If it works, start feeding audio. If it does not, start trouble shooting. Any suspect parts should be ordered fast if not in the shop, as air traffic may be restricted into your market. Check with sister stations, too. Check with other engineers in market to see if you can swap what you need for something any of them need (for those not in engineering, this is very common even if stations are otherwise competitive enemies).
That should give an idea.
My downtime from going off air due to flooding to back at full power was 36 hours. We had the 1 kw second auxiliary on in about 20 hours, but the two main 10 kws were both off for a day and a half till "the plane, the plane" arrived.
