NOTES TO USERSThis map is for use in administering the National Flood Insurance Program. It doesnot necessarily identify all areas subject to flooding, particularly from local drainagesources of small size. The community map repository should be consulted forpossible 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 FloodProfiles and Floodway Data and/or Summary of Stillwater Elevations tables containedwithin the Flood Insurance Study (FIS) Report that accompanies this FIRM. Usersshould be aware that BFEs shown on the FIRM represent rounded whole-footelevations. These BFEs are intended for flood insurance rating purposes only andshould 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 withthe FIRM for purposes of construction and/or floodplain management.Coastal Base Flood Elevations shown on this map apply only landward of 0.0’North American Vertical Datum of 1988 (NAVD 88). Users of this FIRM should beaware that coastal flood elevations are also provided in the Summary of StillwaterElevations table in the Flood Insurance Study Report for this jurisdiction. Elevationsshown in the Summary of Stillwater Elevations table should be used for constructionand/or floodplain management purposes when they are higher than the elevationsshown on this FIRM.Boundaries of the floodways were computed at cross sections and interpolatedbetween cross sections. The floodways were based on hydraulic considerations withregard to requirements of the National Flood Insurance Program. Floodway widthsand other pertinent floodway data are provided in the Flood Insurance Study Reportfor this jurisdiction.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 Universal TransverseMercator (UTM) zone 10. The horizontal datum was NAD 83, GRS 1980spheroid. Differences in datum, spheroid, projection or UTM zones used in theproduction of FIRMs for adjacent jurisdictions may result in slight positionaldifferences in map features across jurisdiction boundaries. These differences do notaffect 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 conversionbetween the National Geodetic Vertical Datum of 1929 and the North AmericanVertical Datum of 1988, visit the National Geodetic Survey website athttp://www.ngs.noaa.gov or contact the National Geodetic Survey at the followingaddress:NGS Information ServicesNOAA, N/NGS12National Geodetic SurveySSMC-3, #92021315 East-West HighwaySilver Spring, Maryland 20910-3282(301) 713-3242To obtain current elevation, description, and/or location information for bench marksshown on this map, please contact the Information Services Branch of the NationalGeodetic Survey at (301) 713- 3242, or visit its website at http://www.ngs.noaa.gov.Base Map information shown on this FIRM was derived from multiple sources.Base map files were provided in digital format by King County GIS, WA DNR, WSDOT,and Pierce County GIS. This information was compiled at scales of 1:12,000 to 24,000during the time period of 1994-2012.The profile baselines depicted on this map represent the hydraulic modeling baselines that match the flood profiles in the FIS report. As a result of improved topographic data, the profile baseline, in some cases, may deviate significantly from the channel centerline or appear outside the SFHA.This map reflects more detailed and up-to-date stream channel configurationsthan those shown on the previous FIRM for this jurisdiction. The floodplains andfloodways that were transferred from the previous FIRM may have been adjustedto conform to these new stream channel configurations. As a result, theFlood Profiles and Floodway Data tables for multiple streams in the FloodInsurance Study Report (which contains authoritative hydraulic data) may reflectstream channel distances that differ from what is shown on this map.Corporate limits shown on this map are based on the best data available at the timeof publication. Because changes due to annexations or de-annexations may haveoccurred after this map was published, map users should contact appropriatecommunity officials to verify current corporate limit locations.Please refer to the separately printed Map Index for an overview map of thecounty showing the layout of map panels; community map repository addresses;and a Listing of Communities table containing National Flood Insurance Programdates for each community as well as a listing of the panels on which each communityis located.For information on available products associated with this FIRM visit the MapService Center (MSC) website at http://msc.fema.gov. Available products mayinclude previously issued Letters of Map Change, a Flood Insurance Study Report,and/or digital versions of this map. Many of these products can be ordered orobtained directly from the MSC website.If you have questions about this map, how to order products, or the NationalFlood Insurance Program in general, please call the FEMA Map InformationeXchange (FMIX) at 1-877-FEMA-MAP (1-877-336-2627) or visit the FEMAwebsite at http://www.fema.gov/business/nfip.

The 1% annual chance flood (100-year flood), also known as the base flood, is the flood that hasa 1% chance of being equaled or exceeded in any given year. The Special Flood Hazard Area isthe area subject to flooding by the 1% annual chance flood. Areas of Special Flood Hazardinclude Zones A, AE, AH, AO, AR, A99, V, and VE. The Base Flood Elevation is the water-surfaceelevation of the 1% annual chance flood.
No Base Flood Elevations determined.Base Flood Elevations determined.Flood depths of 1 to 3 feet (usually areas of ponding); Base Flood Elevationsdetermined.Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); averagedepths determined. For areas of alluvial fan flooding, velocities also determined.
Special Flood Hazard Areas formerly protected from the 1% annual chanceflood by a flood control system that was subsequently decertified. ZoneAR indicates that the former flood control system is being restored to provideprotection from the 1% annual chance or greater flood.Area to be protected from 1% annual chance flood by a Federal floodprotection system under construction; no Base Flood Elevations determined.Coastal flood zone with velocity hazard (wave action); no Base Flood Elevationsdetermined.Coastal flood zone with velocity hazard (wave action); Base Flood Elevationsdetermined.
The floodway is the channel of a stream plus any adjacent floodplain areas that must be kept free ofencroachment so that the 1% annual chance flood can be carried without substantial increases inflood heights.
Areas of 0.2% annual chance flood; areas of 1% annual chance flood withaverage depths of less than 1 foot or with drainage areas less than 1 squaremile; and areas protected by levees from 1% annual chance flood.
Areas determined to be outside the 0.2% annual chance floodplain.Areas in which flood hazards are undetermined, but possible.
CBRS areas and OPAs are normally located within or adjacent to Special Flood Hazard Areas.
