We have what is commonly referred to as a "two-tiered" planning system; a regional level which has area-wide planning functions, and local municipalities which carry-out more detailed planning functions such as zoning.

I would like some views on the need for growth management policy at a regional scale. and some options for a regional growth management policy. More specifically:

Is there a need for a regional growth management policy? If so, what is the planning rationale?

What should the planning horizon be-30 years?40years?more?

What should the planning horizons be for the local municipalities?

Should the planning horizons of both tiers coincide?

Thanks.
