Travel Distance

Please verify that when calculating the minimum 25 linear foot distance from an opening to an exterior designated smoking area, whether or not the measurement can go around solid obstacles. Our project’s smoking area is separated from the entry doors by a 4 foot wide by 17’-9” deep wall perpendicular to the building. The entire area is covered by a 25’-1” deep canopy that provides coverage at the smoking area and extends to the far end of the building. The perpendicular wall will be sealed continuously at the paved exterior patio floor surface, and to the canopy above. While it is 19’-6” from the edge of the door through the solid wall to the nearest point of the smoking area, it is 26’-6” diagonally from the edge of the door to the end of the perpendicular wall at the smoking area. Also, when measuring the 25 linear foot distance from a smoking area to an opening located above, is the measurement taken from grade?
