NOTES

1. No floodway defined because flood hazard area is
contained within a defined channel.

2. Encroachment into flood hazard area is not recom-

mended because of overland flow from upstream

control.

3. Encroachment into the flood hazard area and fill

elevation should consider overland flow from up-

stream control.

4. Total width given includes divided or hydraulically
disconnected flow.
