Staffhasprovidedamatrixofprosandcons(AttachmentA)toassistCouncilindeterminingif theBaseTrailAlignmentisadequateatthistimeorifoneofthesuggestedalternativetrail alignmentswould bea better solution overall. A summaryofthethreealternativetrailalignmentsfollows: AlternativeTrailAlignment 1:BridgeLocationUpstream Thisalternativewouldplacethebridge nearthe northernendoftheBlackberryFarmparkinglot, th nearlyoppositetheteeboxforthe 8greenofthegolfcourse.Thisalternativewouldshorten theportionoftrailthatwouldneedgolfballprotectionfencing,butthebridgewouldneedtobe longertospanthecreekatanobliqueangle.Theobliqueanglespanwouldbenecessaryto avoidencroachmentonMeadowscommonpropertyalongthecreek.Thebridgewouldalso needtoavoidtheexistingStocklmeirorchardwellheadandpump-house,causingthebridge abutmentto berathercloseto one oftheresidentsinthe Meadowsresidentialarea. AlternativeTrailAlignment 2: WestSideTrail ThisalternativewouldroutethetrailneartheMeadowsresidentialarea,fromeitherthecurrently proposedbridgelocationintheBaseTrailAlignmentorfromthebridgeintheupstream location.ThetrailwouldpassbetweentheMeadowspropertyfencelineandthefirstrowof orchardtrees,alongthewesterlyedge oftheStocklmeir property.
