LPB of Subway Station

Dear all, This building has a roof structure that goes beyond the property line in order to shade the sidewalk next to it. It's a public building, that's why. This is a major renovation of a public building so there is some existing infrasctructure next to it like sidewalks and ramps that goes across the side streets that get affected by the project but won't be touched by it otherwise. Must we include such ramps and sidewalks within the LPB? The sidewalks won't be touched, the only way the project is affecting them is because thy are shaded by the roof structure. And the roof strutcture goes beyond the property line. So basically our problem is that the building constructed footprint does not concide with the new roof structure...My question is: can I consider the property line (does not include the complete roof strutcture, the ramps and the sidewalk) as the LEED Project boundary? We will make sure to include the complete roof structure for the credits, like SSc7.2. Thanks for any light you can shed!
