Shadow Easement

Define "shadow". At?ÿ sunset and sunrise the shadow might be infinitely long, although not sharply defined.

Maybe one of these will help.

That is kind of my point exactly. This site the billboard is running North - South (ie viewed while driving E-W), so the morning / evening shadow would be wide, and the noon shadow would be thin.?ÿ?ÿ

Maybe I should note that this is for an existing billboard. It is in the Northern US, about 46?øN. Also they are not asking for a separate easement for the shadow portion, just for it to be included. I think the answer is a hard no, but I want to be open to the idea that it could be defined.?ÿ

Thank you Lurker! I will check these out before our conf. call.

That is an interesting challenge.?ÿ For one thing you may end up dealing with several adjoiners depending on how the land has been split up over time.?ÿ Remember that the sign's shadow will include an area to the southwest and southeast of the sign at this time of year.

It depends on why the owner of the property would care about the shadow. It's different, depending on whether the owner wants to watch the sunrise vs. wants to generate solar electricity. If it's about solar electricity, it might be possible to calculate at what time of day the generation becomes negligible even in full sun, and calculate where the shadow is at that time. But that will depend on the technology of the solar cells, and whether the panel is fixed or tracks the sun.

Perhaps this has been resolved by now. I hope so.

Here are a couple of shadow exhibits submitted for a land-use application in Minneapolis a few years back. There were 6 or 8 of these, showing morning and afternoon shadows at several different times of the year. The architects generated these, probably with an AutoCad routine, though I never heard for sure.

The architects could have submitted hundreds of different shadow exhibits, no two exactly alike. But they didn't do that, and the City planners didn't require it. No one wanted to chase shadows to that extent.

If the billboard is located on farmland, the landowner might be concerned about the effect of its shadow on the crops. That would be easier to define.
