encroachment into the minimum clearwidths of such walkways. The additionalwalkway width, if necessary, can beprovided by a floating landing platformsecured to the edge of the walkway.Care must be taken to maintainfreeboard and cross slope requirements.F2.13 Gangway utility connectionsrequire careful design, installation andmaintenance. Gangways function asutility bridges across the land/waterinterface, providing a flexible linkbetween shoreside and dockside utility lines as follows:# electrical power # potable water supply# telephone # fire suppression# cable TV # fuel# sewage lift-station # oil collection/dischargeF2.14 Accessible GangwaysFloating Landing Platform for GangwayCCF2.14.1 An accessible gangway is an element of an accessible route thatlinks floating docks with walkways, piers, bulkheads, parking areas, buildings,and other accessible marina service and activity centers.F2.14.2 An accessible gangway connects a fixed pier or abutment onshore to a floating dock or other floating structure in a marina, excludinggangways that connect to vessels (ferries, commercial ships, livery boats,charter boats, vessels for hire, common carriers, etc.).F2.14.3 Newly designed, or newly constructed and altered marinafacilities, including gangways, are required to comply with federal and stateaccessibility guidelines which apply to each newly designed or newlyconstructed marina facility.F2.14.4 Altered marina facilities must conform to federal and stateaccessibility guidelines.F2.14.4.1 An “alteration” consists of any change in a primary function thatadds new services or features. Examples would be the addition of electricaloutlets on berths not previously so equipped, the provision of new berths ofa different length or particular characteristic, or the provision of a totally newfeature such as a fueling station, pumpout facility, boat rental service, etc.Routine maintenance work such as the replacement of decking and othercomponents does not constitute an alteration.SECTION F Shoreline Structures - Page 55
F2.14.5 Existing marina facilities not being altered are not affected by newfederal guidelines for recreational boating facilities published in 2002, andupdated and edited in 2004.F2.14.6 Where an existing gangway (or a series of gangways thatconstitutes a single gangway system) is replaced or altered, an increase in thelength of the gangway(s) is not required unless alterations are made to an areacontaining a primary marina function.F2.14.7 Where there is a change in a primary function, and the cost oflengthening an existing gangway is considered to be disproportionate to thecost of overall alterations, the gangway does not have to be lengthened.CCF2.14.8 By reference, anaccessible gangway must complywith certain requirements for anaccessible ramp, including location,width, passing space, head room,surface textures, slope, changes inlevels, doors, egress and areas ofrescue assistance. Since a variableslope gangway is significantlydifferent in nature from a fixed sloperamp, eight (8) exceptions wereSecurity Gate, Gangway and Switchback Rampsprovided in federal guidelinespublished in 2002, the first seven ofwhich were carried over into revised guidelines published in 2004. SeeAppendix B for a side-by-side comparison of ADAAG Section 15.2 (published in2002) and ADA-ABA Sections 1003 and 235 (published in 2004). The ADA-ABAguidelines are presently under review by the Federal Department of Justice.Exception 1.Where an existing gangway or series of gangways is replaced or altered, anincrease in the length of the gangway is not required to comply with 15.2.2unless required by 4.1.6(2).Exception 2.The maximum rise of 30 inches for a ramp does not apply to an accessiblegangway.Exception 3.Where the total length of the gangway or series of gangways serving aspart of a required accessible route is at least 80 feet, the 1:12 maximumslope for ramps specified in ADAAG 4.8.2 shall not apply to thegangway(s).SECTION F Shoreline Structures - Page 56
