How to remove/prevent standing water at campsite???

Dont get govt involved...period.
We had high water one year in a private park they called a consulted with experts. Someone didn't like their recommendations and call county. County made us do eis study and all kinds of other stuff. End result was park bought back or allowed owners to trade lots or not pay dues until problem solved. Fast forward 3 years and everything back to normal. That was after 40,too dollars in eis study's and new road that was 25 feet from where flooded road.
