f. Floodplain Boundaries For the Verde River, 1% and 0.2%-annual-chance flood hazard boundaries were delineated using a Triangulated Irregular Network (TIN) surface provided by Yavapai County. The TIN was generated using 2007 LIDAR data acquired at a 1-meter post spacing for a 193-square-mile area by Vertical Mapping Resources (Reference 9). The 1%-annual-chance flood hazard boundaries for streams studied by approximate methods, as well as redelineated effective detailed studies, were also delineated using the aforementioned TIN. These flooding sources are listed in Section 10.1c above. g. References 1.
