<br />Page 18 <br /> <br />. <br /> <br />100-year flood depth, the assumed depth shall be so <br />stated on the maps. <br /> <br />b. GeomorDhic Features Methods. Approxi- mate 100-year <br />flood boundaries may be determined from a study of <br />geomorphic features on the best available topographic <br />map. <br /> <br />c. Historic Flood Method. Historical flood information <br />may be used directly if the peak discharge can be shown <br />to approximate a 100-year flood and is applicable to <br />the present condi t ions. Hi stori ca 1. flood i nformat ion <br />may be available in goyernment reports on maps that <br />have been prepared for rmajor floods, from high-water <br />marks, frQm gaging station data, or from miscellaneous <br />discharge measurements made in the study area. <br /> <br />D. Published Report and Maps <br /> <br />1. ReDorts. All approximate floodplain information which is <br />presented to the Board for designation and approval shall <br />b~ entitled, dated, and bound .in an individual document. <br /> <br />2. Published MaD Scale. The published flooded area map <br />scale shall be 1 inch equals 2000 feet or such map scale . <br />showi ng greater deta i1 . <br /> <br />L Oualiflcations. All approximate floodplain information shall <br />be developed by a qualified hydrologist or hydraulic engineer <br />under the direct supervision of a professional engineer <br />registered in the State of Colorado, or by an employee of a <br />state or. federal government agency .that has executed a <br />memorandum of understanding or other written agreement with the <br />Board based on a written statement which demonstrates to the <br />satisfaction of the Board their equivalent qualifications to <br />. perform such work in Colorado. <br /> <br />/e~" ,,\. <br />, Go) <br />.
