If your food forest lies between fields and meadows that are sprayed, at least make sure that there is a dense hedge that you do not harvest from and/or other forms of buffer zones, especially in the dominant wind direction. This also helps with the next point.
If your neighbours (might) complain about weeds, a good hedge will also help to avoid the notion of 'blowing over'.
Stay in contact with your neighbours as much as possible from the start, but don't overdo it. Invite them, tell them what you are planning, show them nice pictures of the possible end result, but if they do not understand any of this (yet), leave it alone and wait for a moment of extreme weather or beautiful blossoms or a rich autumn harvest to pick up the communication again. Because that is when you see the power of a food forest.
