Pursuant to Section 1361 of the National Flood Insurance Act of 1968,as amended,communities participating in the NFIP are required to adopt and enforce floodplain management regulations that meet or exceed NFIP criteria. These criteria, including adoption of the FIS report and FIRM,and the modifications made by this LOMR,are the minimum requirements for continued NFIP participation and do not supersede more stringent State/Commonwealth or local requirements to which the regulations apply. We provide the floodway designation to your community as a tool to regulate floodplain development. Therefore,the floodway revision we have described in this letter,while acceptable to us,must also be acceptable to your community and adopted by appropriate community action,as specified in Paragraph 60.3(d)of the NFIP regulations. COMMUNITY REMINDERS We based this determination on the 1-percent-annual-chance flood discharges computed in the FIS for your community without considering subsequent changes in watershed characteristics that could increase flood discharges. Future development of projects upstream could cause increased flood discharges,which could cause increased flood hazards. A comprehensive restudy of your community's flood hazards would consider the cumulative effects of development on flood discharges subsequent to the publication of the FIS report for your community and could,therefore,establish greater flood hazards in this area. Your community must regulate all proposed floodplain development and ensure that permits required by Federal and/or State/Commonwealth law have been obtained. State/Commonwealth or community officials,based on knowledge of local conditions and in the interest of safety,may set higher standards for construction or may limit development in floodplain areas. If your State/Commonwealth or community has adopted more restrictive or comprehensive floodplain management criteria,those criteria take precedence over the minimum NFIP requirements. We will not print and distribute this LOMR to primary users,such as local insurance agents or mortgage lenders; instead,the community will serve as a repository for the new data. We encourage you to disseminate the information in this LOMR by preparing a news release for publication in your community's newspaper that describes the revision and explains how your community will provide the data and help interpret the NFIP maps. In that way,interested persons,such as property owners,insurance agents,and mortgage lenders,can benefit from the information. This revision has met our criteria for removing an area from the I-percent-annual-chance floodplain to reflect the placement of fill. However,we encourage you to require that the lowest adjacent grade and lowest floor(including basement)of any structure placed within the subject area be elevated to or above the Base(1-percent-annual-chance)Flood Elevation. This determination is based on the flood data presently available. The enclosed documents provide additional information regarding this determination. If you have any questions about this document,please contact the FEMA Map Information eXchange(FMIX)toll free at 1-877-336-2627(1-877-FEMA MAP)or by letter addressed to the LOMC Clearinghouse,847 South Pickett Street,Alexandna,VA 22304-4605.

Preliminary copies of the countywide FIRM and FIS report,which will present information for the effective FIRMs and FIS reports for your community and incorporated communities in Weld County,will be distributed for review in approximately 3 months. We will incorporate the modifications made by this LOMR into the Preliminary countywide FIRM before it is distributed,and the modifications will be included when the countywide FIRM becomes effective. As part of this revision,the format of the map panels has changed. Previously,flood hazard information was shown on both the FIRM and the Flood Boundary and Floodway Map(FBFM). In the new format,all BFEs,cross sections,zone designations, and floodplain and floodway boundary delineations are shown on the FIRM,and the FBFM has been eliminated. Some of the flood insurance zone designations were changed to reflect the new format. Areas previously shown as numbered Zone A were changed to Zone AE. Areas previously shown as Zone B were changed to Zone X(shaded). Areas previously shown as Zone C were changed to Zone X(unshaded).
