NOTES TO USERS
This map is for use in ad ministering the Na tio nal Flood Insuran ce Pro gram. It doe snot necessarily identify all areas subje ct to floodin g, pa rticu larly fro m local drainagesources of small size. The community map repository should be consulted forpossible updated or addition al flood hazard in formation .
To obtain more detailed in formation in are as where Base Flood Elevations (BFEs)and/or floodways have been determined, users are encouraged to consult the FloodProfiles and Floodway Data and/or Su mmary of Stillw ate r Eleva tio ns tables con tainedwithin the Flood Insurance Study (FIS) Repo rt that a cco mp anie s th is FIRM. Usersshould be aware that BFEs shown on the FIRM represent rounde d w hole -footelevations. These BFEs are intende d for floo d in surance ra ting p urposes o nly a ndshould not be used as the sole source of flo od elevation in formation . Acco rd ingly,flood elevation data presente d in the FIS Re port sh ould b e utilize d in conjunction withthe FIRM for purposes of constru ctio n a nd/or floo dpla in ma nage me nt.
Coastal Base Flood Elevations shown on this map apply only landward of 0.0’North American Vertical Datum of 19 88 (NAVD 8 8). Users of th is FIRM sho uld b eaware that coastal flood eleva tio ns are also provided in th e Summary of Stillwa te rElevations table in the Flood Insuran ce Stud y R eport fo r this jurisdiction . Eleva tio nsshown in the Summary of Stillw ate r Ele va tions tab le should be used for constru ctio nand/or floodplain manageme nt p urposes whe n they are higher than the elevatio nsshown on this FIRM.
Boundaries of the floodways were computed at cross sections and interpolatedbetween cross sections. The flo odways were b ased o n hydra ulic co nsidera tio ns withregard to requirements of th e National Flo od In su rance Program. Flood way widthsand other pertinent floodwa y data a re provided in the Flood Insura nce Study Re portfor this jurisdiction.
Certain areas not in Special Flood Hazard Are as may b e pro tected by flood controlstructures. Refer to Section 2.4 "Flood Protection Measures" of the Flood InsuranceStudy Report for information on flood con trol structure s for this jurisd iction.
Provisionally Accredited Le vee Notes to Users: Check with yo ur localcommunity to obtain more information, such as th e estimated le vel of protectionprovided (which may exceed the 1-pe rcen t-an nual-ch ance level) an d Emerge ncyAction Plan, on the levee syste m(s) shown as providing protection fo r area s onthis panel. To maintain accreditation , the levee ow ner or co mmun ity is requiredto submit the data and documentation ne cessary to comply with Section 6 5.1 0 ofthe NFIP regulations by Nove mb er 0 1, 20 18. If the commu nity o r own er doesnot provide the necessary data a nd docu me nta tio n or if the da ta anddocumentation provided indica te the levee syste m d oes not comply withSection 65.10 requireme nts, FEMA will revise the flood hazard and riskinformation for this area to reflect de-accredita tio n of th e levee system. Tomitigate flood risk in residua l risk areas, prope rty own ers and residents areencouraged to consider flood in surance an d floodp roofing or o the r prote ctivemeasures. For more informa tion on flood insura nce, interested p arties shou ldvisit the FEMA Website a t http://www.fe ma .go v/na tio nal-floo d-insuran ce -program.
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 d atu m, sp heroid , proje ctio n o r UTM zone s used in theproduction of FIRMs for adjace nt jurisd ictions may result in slig ht positio naldifferences in map features across ju risdiction b ound aries. These d iffere nces do n otaffect the accuracy of this FIRM.
Flood elevations on this ma p are referenced to th e No rth American Ve rtica l Da tum o f1988.

Base Map information shown on the FIRM was derived from multip lesources. Base map files we re p ro vided in digital fo rma t by King County G IS, WADNR, WSDOT, and Pierce Co unty G IS. This information was compiled at scales of1:12,000 to 24,000 during the time period of 199 4-2012 .
The profile baselines depicted on this map represent the hydraulic modeling baselines that match the flood profiles in the FIS re port. As a result of imp ro ved to pograph ic data, the profile baseline, in some cases, may deviate significantly from the channel centerline or appear outside the SFHA.
Based on updated topogra phic in formation , this map refle cts more detailed an dup-to-date stream channel configurations and floodplain delineations thanthose shown on the previo us FIRM for this jurisdiction . As a re su lt, th e FloodProfiles and Floodway Data table s for multiple stre ams in the FloodInsurance Study Report (w hich co nta ins authoritative hydraulic da ta) may reflectstream channel distances th at differ fro m wha t is shown on the ma p. Also, the road to floodplain relationship s fo r unrevise d stre ams ma y differ fro m what isshown on previous maps.
Corporate limits shown on this map are based on the best data available at the timeof publication. Because cha nges d ue to ann exations or d e-anne xa tions may haveoccurred after this map w as p ublish ed, map use rs should contact app ro priatecommunity officials to verify current corpo rate limit loca tio ns.

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); 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.
