On a Site Plan what is the proper way to offset an irregular shaped lot line ( i.e. water frontage ) to establish the setback line ?
In my experience you can't really just offset the frontage line in it's entirety due to it's irregular shape you actually end up with
different setbacks at various points along the line. In other words due to the irregular shape not all parts of the line are being moved
back at an equivalent 90 degree angle. Alternatively if you try to offset individual parts of the line at 90 degrees you change the shape
of the line. So how is it typically done ?
