Looks like you may have finally gotten some rain in Texas. That's good.
When I relocated to here, if we were interested in a house, we got some topographical maps and looked at them before we made an offer. I'm 40 vertical feet above creek level where I am now. I don't expect to flood here, though the road did wash in heavy rains last year.
We did not even consider a couple of nice new houses we looked at. They were built lower than the road. In a heavy rain, water would flow along the road and come down the driveway to the house. I could have done some landscaping and directed the water away from the house, but the driveway would still wash out. It would be a constant maintenance issue.
It seems like when a lot of people on this forum plan their coops and runs, they only think about the good days. I try to think of how it will work when the days are not really good. Maybe I'm a pessimist at heart. I guess maybe you have to be an optomist to be a developer.
