Our project has a rear service entrance off a public alley. At this entrance the face of building is set 5 feet back from the property line and 7.5 feet back from the face of curb at the alley. In this situation may we use face of curb for the 0.10 horizontal and vertical fc limit (LZ2) or must we use the property line (which is the LEED boundary)? Thanks very much for your assistance.
