I'd like to see a challenge to these stupid laws. I can understand restricting wells and such if a person doesn't own the mineral / underground water rights. But catching water before it even reaches the ground? And even the most aggressive collection system captures what? A few thousand gallons? Hardly enough to affect anything downstream. Drop in the bucket.
We have grasped the mystery of the atom and rejected the Sermon On The Mount.
That is illegal in Colorado as well, and probably some other states. I suppose it's because you are taking water out of the watershed without paying for it.
where I was building in summit county we were required to put in retention ponds to offset the slab and any concrete or asphalt to hold the runoff. they do have irrigation ditches in the southern part of the state and get real picky about taking water out of them
