There is a library project I'm working on which has a policy of no smoking within 100 feet from the entrance.  The thing is it is next to neighboring business that are are within the 100 feet and required 25 feet boundary.  How would I draw the non-smoking boundary line?  Can i just shorten the boundary to the property line of the project before it crosses in into the other business?  And even though LEED says "required 25 feet", would 100 feet be alright?  I never read anything saying 25 feet was the maximum distance, hence why I'm asking.
