Further to the thread asking which golden era course could not be built today, I would suggest:
In Canada, these are some of the major roadblocks to building golf courses.
1. No golf features below the 100 year flood threshold.
2. Setback of 30 metres from any river or stream.
3. No cutting of hardwood forests.
4. 200 metre setback from any agricultural buildings.
Some examples would be: Banff, Jasper, Capilano, Highland Links, St. George, Thornhill, Ancaster (Hamilton) Mississaugua, etc.
