Table 2 <br />shows the history of maps in each community, Except where noted by Revision or LOMR, the <br />countywide FIS directly incorporates information from the most recent FIS study for each <br />community. <br /> <br /> a e .

Copies of the request letter are included in the Appendix of this report, <br /> <br />Because designation of the Adams County incorporated areas will take place under separate <br />resolution (resolution no. 00-527), the request letters and community responses for the <br />incorporated areas are contained in a separate document contained in the file for that resolution, <br /> <br />4 <br />
