<br />NOTES

<br />USERS
<br />
<br />TO
<br />
<br />This map is for use in administering the National Flood Insurance Program. It
<br />does not necessarily identify all areas subject to flooding, particularly from local
<br />drainage sources of small size. The community map repository should be
<br />consulted for possible updated or additional flood hazard information.
<br />
<br />105009'22.5"
<br />39058'07.5"
<br />
<br />To obtain more detailed information in areas where Base Flood Elevation
<br />(BFEs) and/or floodways have been determined, users are encouraged to consult
<br />the Flood Profiles and Floodway Data tables contained within the Flood Insur-
<br />ance Study (FIS) report that accompanies this FIRM. Users should be aware that
<br />BFEs shown on the FIRM represent rounded whole-foot elevations. These BFEs
<br />are intended for flood insurance rating purposes only and should not be used
<br />as the sole source of flood elevation information. Accordingly, flood elevation
<br />data presented in the FIS should be utilized in conjunction with the FIRM for
<br />purposes of construction and/or floodplain management.
<br />
<br />Coastal Base Flood Elevation (BFEs) shown on this map apply only land-
<br />ward of 0.0' National Geodetic Vertical Datum (NGVD}. Users of this FIRM
<br />should be aware that coastal flood elevations may also be provided in the
<br />Summary of Stillwater Elevations table in the Flood Insurance Study report for
<br />this community. Elevations shown in the Summary of Stillwater Elevations table
<br />should be used for construction, and/or floodplain management purposes when
<br />they are higher than the elevations shown on this FIRM.
<br />
<br />Boundaries of the floodways were computed at cross sections and interpolated
<br />between cross sections. The floodways were based on hydraulic considerations
<br />with regard to requirements of the National Flood Insurance Program. Floodway
<br />widths and other pertinent floodway data are provided in the Flood Insurance
<br />Study report for this jurisdiction.
<br />
<br />Certain areas not in Special Flood Hazard Areas may be protected by flood
<br />control structures. Refer to Section 2.4 "Flood Protection Measures" of
<br />the Flood Insurance Study report for information on flood control structures
<br />in this jurisdiction.
<br />
<br />The projection used in the preparation of this map is Universal Tranverse
<br />Mercator (UTM) Zone 13. The horizontal datum is NAD27, CLARKE1866
<br />spheroid. Differences in datum, spheroid, projection or UTM zones used in
<br />the production of FIRMs for adjacent jurisdictions may result in slight positional
<br />differences in map features across jurisdiction boundaries. These differences
<br />do not affect the aGcuracy of the FIRM.
<br />
<br />Flood elevations on this map are referenced to the National Geodetic Vertical
<br />Datum of 1929. These flood elevations must be compared to structure and
<br />ground elevations referenced to the same vertical datum. For information
<br />regarding conversion between the National Geodetic Vertical Datum of 1929
<br />and the North American Vertical Datum of 1988, visit the National Geodetic
<br />Survey website at www.ngs.noaa.gov or contact the National Geodetic Survey

<br />Base map information shown on this FIRM was provided in digital format by
<br />U.S. Bureau of Census TIGER files and have been geopositionally corrected.
<br />
<br />Corporate limits shown on this map are based on the best data available
<br />at the time of publication. Because changes due to annexations or de-annexations
<br />may have occurred after this map was published, map users should contact
<br />appropriate community officials to verify current corporate limit locations.

<br />Please refer to the separately printed Map Index for an overview map of the
<br />county showing the layout of map panels; community map repository addresses;
<br />and a Listing of Communities table containing National Flood Insurance Program
<br />dates for each community as well as a listing of the panels on which each
<br />community is located.

<br />Letters of Map Amendment revising portions of this panel, and digital versions

<br />
<br />This map reflects more detailed and up-to-date stream channel configurations
<br />than those shown on the previous FIRM for this jurisdiction. The floodplains
<br />and floodways that were transferred from the previous FIRM may have been
<br />adjusted to conform to these new stream channel configurations. As a
<br />result, the Flood Profiles and Floodway Data tables in the Flood Insurance
<br />Study report may reflect stream channel distances that differ from what is
<br />shown on this map.

<br />
<br />The 1 % annual chance flood (100-year flood), also known as the base flood, is the flood
<br />that has a 1 % chance of being equaled or exceeded in any given year. The Special
<br />Flood Hazard Area is the area subject to flooding by the 1 % annual chance flood. Areas
<br />of Special Flood Hazard include Zones A, AE, AH, AD, AR, A99, V, and VE. The Base
<br />Flood Elevation is the water surface elevation of the 1 % annual chance flood.

<br />FLOODWAY AREAS IN ZONE AE
<br />
<br />The flood way is the channel of a stream plus any adjacent floodplain areas that must be
