Wow, Atomo - good work digging through all that legalize. I acknowledge the hard work that is (reading stuff like that makes my head hurt!)
I am on
land that we call "Agricultural Land Reserve" (ALR). As you've identified, it has special rules which are generally helpful, but not always. We still need permits, but it's harder for the Municipality to say "no".
A major benefit is our "farm taxes" are far lower than normal property taxes. We can't get them unless our "farm income" is over a certain dollar value, but we do that easily with Hubby's
chicken business which we do totally as farm gate sales. We tried going to a farmers market, but the cost/benefit ratio just wasn't there.
So it really is worth researching what can be done legally, and I'm impressed that you've thought this through from both the legal and the good of the land and the good of the planet perspectives! I can't wait to see your building and
water plans.
