Any Suggestions on Organizations to donate to that will benefit South La

My family and I are in NW La and were in the flood we had in February. My wife handles all claims for LSU and The Louisiana Housing Authority. We know exactly how bad it is. All Livingston Parish Schools were flooded for an example. My wife is got so on her plate that we haven't spoken much this week, even though we both work from home. So we know how bad it is.
My point for starting this thread is to find the best organizations to donate money to that will directly benefit those effected. A friend of mine has some collectibles that are going for $15k - $30k on eBay. I'm going to list on there through my eBay store with proceeds going to the best places possible.
The last words she said to me before running out the door was that FEMA was just giving loans. I'll have to find out more about that when we have 5 minutes to talk.
So I'd appreciate all the suggestions I can get

Thanks in advance
