<br />3. Inundation Maps. Generally, an inundation map depicting the hazard <br />areas determined for the assumed breach condition and the large flood without <br />breach condition should be included with the plan. <br /> <br />Describe the methods used to determine inundation boundaries, maximum <br />water surface elevations and travel times of the flood wave to significant <br />locations. <br /> <br />The maps should be developed at a scale sufficient to identify features <br />within the area subject to inundation or possible danger related to the flood. <br />However, the accuracy and limitations of the information presented on the maps <br />should be discussed. It may be appropriate to supplement the inundation maps <br />with water surface profiles at critical areas. (See Section I-D4.) <br /> <br />4. Narrative Description. Development of the flood plain below some <br />dams is sparse and the expense of preparing detailed inundation maps is not <br />warranted. A narrative description of the potential flooding can be provided <br />and supplemented by vicinity maps with pertinent information at key locations. <br />Individuals living between key locations can estimate their vulnerability by <br />interpolating data from locations upstream and downstream of their site. <br />Information on depth of flooding and travel for floods to reach specific <br />locations can also be provided. <br /> <br />16 <br /> <br />~ <br />
