Purpose of Historical Preservation Preserve the Function and Form of Historically Important elements of the Built Environment. Dinky: – Functioning since 1865 – Current Form since about 1915 – Station moved in about 1986 to current location

Walk&Ride Accessibility Lost by Moving the Dinky Terminus South Walk&Ride Accessibility Lost by Moving the Dinky Terminus South Assumptions: 1. All walk in a straight line to the station 2.All Walk&Ride trips production/attraction are uniformly distributed in the half plane north of the current terminus. 3. Walk&Ride Area Lost =~ R*D*(2*cos  sin  ) where R = prime walk distance D = Distance Terminus moved (460 ft)  = sin -1 (D/R) Assumptions: 1.
