(a) An inundation map prepared under 11 AAC 93.157(b) or 11 AAC 93.164 must
(1) indicate the extent of flooding below a dam after failure under the normal operating level of the reservoir, under the inflow design flood, and under other scenarios as the department considers necessary to evaluate danger to life and property;
(2) identify downstream structures or other development, flood wave depth and arrival times, roads, evacuation routes, staging areas, and other information required by the department to minimize danger to life and property; and
(3) be based on a dam break analysis, if required.
(b) For purposes of 11 AAC 93.164 and 11 AAC 93.171, the information for determining the inflow design flood shall be developed in substantial accordance with
(1) the Federal Emergency Management Agency's Federal Guidelines for Dam Safety: Selecting and Accommodating Inflow Design Floods for Dams (FEMA 94), as revised as of October 1998 and adopted by reference; or
(2) methods approved by the department that adequately assess and characterize the design hydrology, and that are based on the hazard potential classification assigned under 11 AAC 93.157.
(c) In this section, "inflow design flood" means the flood flow above which the incremental increase in the downstream flood caused by a failure of the dam does not result in any additional danger downstream.
