I work for a rural planning commission in Canada (New Brunswick). We're currently putting together a rural plan for a rapidly growing parish (situated just outside a major urban centre).
We'd like to prohibit residential lot subdivision along minor highways, hopefully leading away from one-acre lots stretched out along the road, and leading to more dense residential subdivisions off of the minor highways.
We're not sure how well this will go over with our community working group - they're willing to place restrictions on commercial and industrial development, but residential development is sacred.
How have you dealt with rural sprawl in your rural plans?
