I don’t have an opinion whether Paine Field should allow expanded commercial air service but I have personal experience with changing conditions that affect property ownership. When my home was originally built in the 1960s, the lot behind mine was divided between the adjoining property owners so it would become an “unbuildable lot.” When I bought this home in 1987, I was told by the real estate agent that the lot behind me was “unbuildable.” Over the years, the allowable lot size by code became smaller, until the remaining largest owner now had a “build-able” lot! When we protested, we were told we could be sued for interfering with a legal right to build on a lot that met the current code!
I have had a neighbor in my “unbuildable” backyard for 10 years because “the times they are a’changin!” The moral seems to be, no matter how much you were promised, how right you are, or how hard you fight, eventually the tide of progress will engulf your best efforts. My sincere condolences for your lost property values.
