<br />Rule 5. Standards for Delineation of Detailed FloodDlain Information: To <br />qualify as detailed floodplain information, the standards of this <br />rule with consideration of the effects of dams and levees being <br />subject to the criteria of rules 7 and 8, respectively, must be met. <br /> <br />A. Topographic Base Mapping <br /> <br />1. Work MaD. The work map shall be a line drawing showing <br />contours and topographic features or an orthophoto map <br />showing contours on a photographic background. Work maps <br />with a photographic background prepared by conventional <br />rectification methods which meet the accuracy standards <br />described herein shall be acceptable. <br /> <br />2. Features. The following minimum information shall be <br />shown on the work maps: <br /> <br />a. Natural features such as hills, depressions, trees and <br />vegetation. <br /> <br />b. <br /> <br />Cultural features such as streets, roads, <br />railroads, airfields, levees, dikes, dams, <br />fences, powerlines, and other prominent <br />features and landmarks. <br /> <br />highways, <br />buildings, <br />man-made <br /> <br />c. <br /> <br />Hydrologic features such as rivers, <br />reservoirs, irrigation ditches, canals, <br />(including both banks of a stream). <br /> <br />streams, lakes, <br />and channels <br /> <br />d. Reference features such as north arrow, grid lines, <br />section corners, reference monuments, corporate limits, <br />contours and spot elevations. <br /> <br />e. <br /> <br />Geographic orientation <br />as names of principal <br />and reference features. <br /> <br />and appropriate notations such <br />natural, cultural, hydrologic, <br /> <br />The work map may contain, but is not required to show, <br />property lines and section lines. Fences, power lines, <br />trees, and vegetation in platted areas may be omitted if it <br />would improve clarity. <br /> <br />3. <br /> <br />Ground Control. The vertical ground <br />spot elevations, and cross-sections <br />United States Coast and Godetic Survey <br /> <br />control, <br />shall be <br />(USC&GS) <br /> <br />contours, <br />based on <br />or United <br /> <br />-7- <br />
