2. Only roof slope, gutters, and downspouts are to be used for removal of
rainwater.
3. Downspouts should not conflict with any door, window, or clerestory window.
4. Rainwater should not discharge from the edge of an upper roof directly onto a
lower roof or from any roof or gutter directly onto the ground.
