DETERMINATION
This document provides the determination from the Department of Homeland Security's Federal Emergency Management Agency (FEMA) regarding
a request for a Letter of Map Revision (LOMR) for the area described above. Using the information submitted, we have determined that a revision to
the flood hazards depicted in the Flood Insurance Study (FIS) report and/or National Flood Insurance Program (NFIP) map is warranted. This
document revises the effective NFIP map, as indicated in the attached documentation. Please use the enclosed annotated map panels revised by
this LOMR for floodplain management purposes and for all flood Insurance policies and renewals in your community.
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

DETERMINATION DOCUMENT (CONTINUED)
COMMUNITY INFORMATION
APPLICABLE NEW REGULATIONS/COMMUNITY OBLIGATION
We have made this determination pursuant to Section 206 of the Flood Disaster Protection Act of 1973 (P.L. 93-234) and in accordance with
the National Flood Insurance Act of 1968, as amended (Title XIII of the Housing and Urban Development Act of 1968, P.L. 90-448), 42
U.S.C. 4001-4128, and 44 CFR Part 65. 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 LOMB 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 LOIVIR 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 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, Alexandria, VA 22304-4605. Additional Information about the NFIP is available on our website at

STATUS OF THE COMMUNITY NFIP MAPS
We will not physically revise and republish the FIRM and FIS report for your community to reflect the modifications made by this LOMB
at this time. When changes to the previously cited FIRM panel(s) and FIS report warrant physical revision and republication in the future,
we will incorporate the modifications made by this LOMB at that time.
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).
Portions of the revision area have been annexed by the Town of Frederick; however, these corporate limits changes are not reflected in this
LOMR.
This determination is based on the flood data presently available. The enclosed documents provide additional information regarding this determination. If you have any
