Consider buying lunch once a year for growers or other people who can help you or have equipment you might need in a flood. If they are willing, arrange for specific help or equipment that you might need. Growers have backhoes, front-end loaders, and other equipment that you might need in a flood emergency. You can even make use of heavy-duty pickup trucks and trailers that can be quickly loaded and hauled off-site.
The good news is that growers already know how to operate their own equipment. Include willing growers and others in your emergency management plan. Of course, be clear that their operations come first and build that into your expectations. Make sure you talk with your insurance company about any liability issues regarding these volunteers being injured
