It does not necessarily identify all areas subject to flooding, particularly from local drainage sources of small size. The community map repository should be consulted for possible updated or additional flood hazard information. To obtain more detailed information in areas where Base Flood Elevations (BFEs) and/or floodways have been determined, users are encouraged to consult the Flood Profiles and Floodway Data and/or Summary of Stillwater Elevations tables contained within the Flood Insurance Study (FIS) report that accompanies this FIRM. Users should be aware that BFEs shown on the FIRM represent rounded whole-foot elevations. These BFEs are intended for flood insurance rating purposes only and should not be used as the sole source of flood elevation information. Accordingly, flood elevation data presented in the FIS report should be utilized in conjunction with the FIRM for purposes of construction and/or floodplain management. Coastal Base Flood Elevations (BFEs) shown on this map apply only landward of 0.0' North American Vertical Datum of 1988 (NAVD 88). Users of this FIRM should be aware that coastal flood elevations are also provided in the Summary of Stillwater Elevations table in the Flood Insurance Study report for this jurisdiction. Elevations shown in the Summary of Stillwater Elevations table should be used for construction and/or floodplain management purposes when they are higher than the elevations shown on this FIRM. Boundaries of the floodways were computed at cross sections and interpolated between cross sections. The floodways were based on hydraulic considerations with regard to requirements of the National Flood Insurance Program. Floodway widths and other pertinent floodway data are provided in the Flood Insurance Study report for this jurisdiction. Certain areas not in Special Flood Hazard Areas may be protected by flood control structures. Refer to Section 2.4 "Flood Protection Measures" of the Flood Insurance Study report for information on flood control structures for this jurisdiction. The projection used in the preparation of this map was Lambert Conformal Conic State Plane Maryland Zone 1900. The horizontal datum was NAD83, GRS1980 spheroid. Differences in datum, spheroid, projection or State Plane zones used in the production of FIRMs for adjacent jurisdictions may result in slight positional differences in map features across jurisdiction boundaries. These differences do not affect the accuracy of this FIRM. Flood elevations on this map are referenced to the North American Vertical Datum of 1988. These flood elevations must be compared to structure and ground elevations referenced to the same vertical datum. For information regarding conversion between the National Geodetic Vertical Datum of 1929 and the North American Vertical Datum of 1988, visit the National Geodetic Survey website at http://www.ngs.noaa.gov/ or contact the National Geodetic Survey at the following address: NGS Information Services NOAA, N/NGS12 National Geodetic Survey SSMC-3, #9202 1315 East-West Highway Silver Spring, Maryland 20910-3282 (301) 713-3242 To obtain current elevation, description, and/or location information for bench marks shown on this map, please contact the Information Services Branch of the National Geodetic Survey at (301) 713-3242 or visit its website at http://www.ngs.noaa.gov/ . Base map source: Base map information shown on this FIRM was provided in digital format. Road centerline and political boundary files were provided by the GIS Division of Allegany County Government. Based on updated topographic information, this map reflects more detailed and up-to-date stream channel configurations and floodplain delineations than those shown on the previous FIRM for this jurisdiction. As a result, the Flood Profiles for North Branch Potomac and Potomac Rivers in the Flood Insurance Study report (which contains authoritative hydraulic data) may reflect stream channel distances that differ from what is shown on the map. Also, the road to floodplain relationships for unrevised streams may differ from what is shown on previous maps. Corporate limits shown on this map are based on the best data available at the time of publication. Because changes due to annexations or de-annexations may have occurred after this map was published, map users should contact appropriate community officials to verify current corporate limit locations. Please refer to the separately printed Map Index for an overview map of the county showing the layout of map panels; community map repository addresses; and a Listing of Communities table containing National Flood Insurance Program dates for each community as well as a listing of the panels on which each community is located. Contact the FEMA Map Information eXchange at 1-877-336-2627 for information on available products associated with this FIRM. Available products may include previously issued Letters of Map Change, a Flood Insurance Study report, and/or digital versions of this map. The FEMA Map Information eXchange may also be reached by Fax at 1-800- 358-9620 and its website at http://www.msc.fema.gov/ .

To mitigate flood risk in residual risk areas, property owners and residents are encouraged to consider flood insurance and floodproofing or other protective measures.

The floodways were based on hydraulic considerations with regard torequirements of the National Flood Insurance Program. Floodway widths and otherpertinent floodway data are provided in the Flood Insurance Study report for thisjurisdiction.
Certain areas not in Special Flood Hazard Areas may be protected by flood controlstructures. Refer to Section 2.4 "Flood Protection Measures" of the Flood InsuranceStudy report for information on flood control structures for this jurisdiction.
The projection used in the preparation of this map was Lambert Conformal Conic StatePlane Maryland Zone 1900. The horizontal datum was NAD83, GRS1980 spheroid.Differences in datum, spheroid, projection or State Plane zones used in the production ofFIRMs for adjacent jurisdictions may result in slight positional differences in map featuresacross jurisdiction boundaries. These differences do not affect the accuracy of this FIRM.
Flood elevations on this map are referenced to the North American Vertical Datum of1988. These flood elevations must be compared to structure and ground elevationsreferenced to the same vertical datum. For information regarding conversion betweenthe National Geodetic Vertical Datum of 1929 and the North American Vertical Datum of1988, visit the National Geodetic Survey website at http://www.ngs.noaa.gov/ or contactthe National Geodetic Survey at the following address:

Based on updated topographic information, this map reflects more detailed and up-to-datestream channel configurations and floodplain delineations than those shown on theprevious FIRM for this jurisdiction. As a result, the Flood Profiles for North BranchPotomac and Potomac Rivers in the Flood Insurance Study report (which containsauthoritative hydraulic data) may reflect stream channel distances that differ from what isshown on the map. Also, the road to floodplain relationships for unrevised streams maydiffer from what is shown on previous maps.
Corporate limits shown on this map are based on the best data available at the time ofpublication. Because changes due to annexations or de-annexations may have occurredafter this map was published, map users should contact appropriate community officials toverify current corporate limit locations.

ACCREDITED LEVEE NOTES TO USERS:Check with your local community to obtain more information, such as the estimatedlevel of protection provided (which may exceed the 1-percent-annual-chance-level)and Emergency Action Plan, on the levee system(s) shown as providing protectionfor areas on this panel. To mitigate flood risk in residual risk areas, propertyowners and residents are encouraged to consider flood insurance andfloodproofing or other protective measures. For more information on floodinsurance, interested parties should visit the FEMA Website athttp://www.fema.gov/national-flood-insurance-program.
