I wish I was able to go to help. Not sure what I could do at this point in time.
Any RV groups or RVers headed that way?
My initial reaction was to hitch up my 14' fishing boat and head down there (24+ hrs travel time). It soon occurred to me that there are local boaters and the Cajun Navy that are equipped, local, possibly trained, and have more experience than I have. I might have been a drain on valuable resources.
I am still considering loading my tools and heading down for the recovery effort. I have a lot of experience in construction and some experience with mold mitigation. I am going to make more inquiries before a decision is made. There will be plenty of time for all that.
FWIW, I lived in Bellaire for a year and worked out of Houston for about 6 yrs. My first year in Houston was spent in underground construction, subcontracted to Southwestern Bell. There will be a loooong time until everything is dried out and water is at typical levels.
Tonight, I found this webpage that has contact information for those wanting to donate resources for the disaster recovery. Most organizations are local so information should be pertinent:
