We are building a hotel with LEED NC v2009.

I have a couple projects where the property line falls a few feet from reaching the bordering roadway. In these cases, can the lighting boundary extend to the center of the road?

These questions are in regard to exterior lighting power calculation. I am fine with the general approach and calculation.
