This post by Peter Bray over at Land Use Watch is an excellent first hand account of the inanity that is Measure 37.
One of the things Measure 37 doesn't require, but should, is some sort of proof that the landowner had planned on developing their property in such a way that was later prohibited PRIOR to land use/ zoning laws going into effect. What we're left with is a situation where landowners get to pull a Pee Wee Herman claiming "I meant to do that." Long term property owners who had previously no plans of development suddenly saw dollar signs after the passage of Measure 37.
I've been hoping the legislature addresses some of the biggest issues in Measure 37 but now I'd just like to see the thing repealed.
