RecommendationSummary
ThestaffrecommendsapprovalofBCDCPermitApplicationNo.2013.007.00,totheSan
FrancisquitoCreekJointPowersAuthorityfortheSanFrancisquitoCreekFloodProtectionand
EcosystemRestorationProjectlocatedontheborderbetweenSantaClaraandSanMateo
Counties,which,asconditioned,willauthorizethefollowingactivities:
(1) Removalofportionsoftheexistingsouthernlevee,whileleavingasmallsectionof
theleveetocreateFriendshipIsland,andrealigningthesouthernleveetoallowfor
increasedflowcapacitytoalleviatefloodingwithintheCitiesofEastPaloAltoand
PaloAlto;
(2) RepairingportionsofdegradedleveesalongtheFaberTractMarsh,restoringa
portionoftheOuterFaberMarshleveetomarshplainelevation,andplacingriprap
inthechannelalonglevees,infrontoffloodwallsandaroundFriendshipIslandfor
shorelineprotection;
(3) RestoringandcreatingtidalmarshhabitatsalongtheedgesofSanFrancisquito
Creek(SFC),creatingadditionalhightiderefugiaenhancementsinOuterFaber
MarshandenhancingtransitionzonehabitatsalongFaberTractMarsh;
(4) Installingrequiredpublicaccessimprovementsandinterpretivesignagebothinside
andoutsideBCDC’sjurisdiction;and

(5)Maintenanceofexistingleveeslopesandpublicaccessareas.
TheSanFrancisquitoCreekFloodProtectionandEcosystemRestorationproject(SFBayto
Highway101)willbeconstructedoveratwo-yearperiod,duringtheauthorizedin-streamwork
windowsfromJune1stthroughOctober15thandout-of-channelwindowfromMay1stthrough
October15th,unlessanextensionoftimeisapprovedonbehalfoftheCommission.Thefirst
yearofconstructionwillincludeallutilitylinework,constructingasetbackportionoftheSFC
southlevee(ExhibitB)withinthePaloAltoGolfCourse(golfcourse),constructingfloodwallsin
specifiedlocationsalongthecreek,excavatingapproximately1,470cubicyardsofsediment
fromwithinthechannel,andremovingapproximately37,680squarefeet(3,380cy)offillfrom
theOuterFaberMarshlevee.Inthesecondyearofconstruction,theprojectincludesremoving
60,380squarefeetoffillfromtheexistingSFClevee(leavinganapproximately13,830square
footsectiontocreateFriendshipIsland),constructing2,060squarefeet(0.05acre)ofpile-
supportedfillfortheboardwalkconnectingFriendshipIslandtotherealignedsouthernlevee,
placingapproximately56,530squarefeetofriprapwithintheCommission’sjurisdiction,and
finishingconstructionofallfloodwallsandconnectionswithadjacentlevees.
Additionally,theprojectwillimprovehabitatinthecreekandadjacentareasandincludes:
placingbetween55and110cy(1,250squarefeet)ofcleanfillinOuterFaberMarshtocreate
hightiderefugiaislands;importingsmallamountsofcleanfillandplantingnativevegetation
alongapproximately6.0acresofleveessurroundingFaberMarshtoenhancehightiderefuge
areas;andbothcreatingandrestoring3.44acresofhighmarshandtransitionzonehabitats
alongtheedgesoftheSanFrancisquitoCreek.Followingthecompletionofallconstruction
activitiesrevegetationofnativetidalsaltmarshplantswilloccurbetweenNovember1stand
January31stof2018andthesuccessofthehabitatrestorationwillbemonitoredannually
betweenSeptember1standDecember1stfollowingthefirstgrowingseason,foratleastfive
yearsoruntilsuccesscriteriainthefinalapprovedMitigationandMonitoringPlanarereached.
The total project site is 263.5 acres, 13.6 acres of which are within the Commission’s
jurisdictionalongthelowerreachoftheSanFrancisquitoCreek.Theprojectitselfwillresultin
approximately24,000squarefeetofBayfill,whichincludesbothsolidfillandpile-supportedfill

(Table 1). However, with the realignment of the southern levee along the creek and the
loweringofaportionoftheOuterFaber levee,theprojectwillresult inanet increase inBay
surfaceareaofapproximately25,535squarefeet(0.59acres),restoreapproximately3.44acres
oftidalmarshhabitatsandenhance6.0acresofhightiderefugeareaswithintheCommission’s
