The map does not show flood profiles, base flood elevations, or sufficient <br />detail in order for County officials, engineers, developers, and land owners to make floodplain <br />determinations with any certainty. <br /> <br />The flood hazard map prepared by Wilbur Engineering shows Zone AE, X and Y floodplains for <br />the Dolores River and Zone A floodplain for Silver Creek. A comparison of the new flood <br />Hazard map with the older FIRM shows some lateral migration of the Dolores River. Based on <br />field observation, it appears that the new flood hazard map accurately depicts the floodplains. <br />CWCB's floodplain designation will utilize this new map as the official floodplain map for the <br />Town of Rico for floodplain management, regulation and land use purposes subject to previous <br />discussions in this report. A copy of the flood hazard map is included in the appendices. It <br />should be noted that the current the 1986 FIRM shall be used for flood insurance purposes until <br />the newer map is recognized by FEMA. <br /> <br />The Colorado Water Conservation Board can be contacted to request technical assistance for <br />approximate floodplain analyses as needed. <br /> <br />6 <br />
