LH2 asked: “Just an hypothetical question, say you have a 500m x 50m strip of land. I wonder if you could subdivide those into, say, five properties 500m long x10m wide, and use them alternatively. Shouldn't that give you 140 days a year of unregulated operations?”
No, it is all one planning unit and there is only one set of 28 days. Case law, not the original act.
By the way, there are other potential gotchas about the 28 day rule, too numerous and contentious to go into here. Getting it wrong can lead to legal action and mounting costs.
[As I wrote before: Anything I say about planning is as an unqualified person, and free, so it may be worth no more than you pay for it.]
