It's usually dry this time of year, but we had a lot of rain over the winter. It doesn't get more than a few inches deep. I sincerely doubt there are any gators because of the shallow depth, but it is prime habitat for water moccasins.
We weren't allowed to choose our own fence (you're lucky to find a place here that lets you), so we planted bamboo for privacy. We will probably sell the place before it's fully grown, but it's doing a decent job now.
I lined the fence with pet screen. I started the project when we moved in, but procrastinated a few weeks, until I killed a diamondback in the yard. I suppose it's not completely snake proof, but it prevents anything from getting that doesn't want to climb up the fence.
We are replacing some of the builder's work. The baseboards were shit, and the company that installed the wood didn't do the best job with the quarter rounds either. We removed the 3.25" baseboards and put in 7.25" base.
