Drainage

If ground is flat naturally then you guys in the South don't need a North Islander to tell you what liquiefaction is.
If ground has a slope then it's a good idea to do slit trenches say 300mm or one narrow digger bucket wide and maybe 600mm deep running downhill with an interceptor drain across the top of the slope and a bigger runoff drain at the bottom of the slop leading down to a soakpit full of rocks or a pond outlet or some such. Fill em with rock or gravel

Also the piled earth berms are going to weigh down on the ground and squeeze water out of the ground slowly over a couple of years (if clay) so they will be wet alongside - slit trenches underneath will carry some of this water away

This will take a lot of gravel but it's easier at the beginning of the project


Also whilst digging, if funds allow, a shallow trench with electrical conduit all sealed up and a draw wire running through would be a good extra if run down the line of some ranges - you could later run cables for turning target control or moving target control etc

It will be good to see this project take shape
