Great looking flying site.
We have 4 flying sites, 2 on local parks, 1 on university property & 1 on private land. One advantage of living in the middle of nowhere, you can fly almost anywhere you want. The main flying site uses a dirt runway, works great, just need to spray it about 3 times a year to keep the weeds out. Not sure if a dirt runway would work for your site or not. If you are going to have a road grader, I would highly recommend a crown in the middle of runway, just like they use in roads. You want the water to run off the runway as soon as possible, don’t let it run down the length of the runway.
