2. The FW is required to provide a complete separation between the two portions of the building. The northern portion of the wall terminates at the exterior wall, however the roof overhang of the existing school building (at main entry doors) continues past the proposed end of the FW. The FW should therefore continue westward to at least the 90 degree juncture between the lower roof and new exterior wall. Section 706.1 a. The FW should continue in the western direction a minimum of 4 feet past the 90 degree juncture to avoid the issues created by compliance with Sections 706.5.1 & 706.5.2.
