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 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 Web site at

COMMUNITY INFORMATION
APPLICABLE NFIP 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
communitys 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 any permits required by Federal 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 1-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 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 Web site 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
LOMR at this time. When changes to the previously cited FIRM panel and FIS report warrant physical revision and republication in the
future, we will incorporate the modifications made by this LOMR at that time.
