Reader Note
Since production of the Final Environmental Impact Statement document, nonmotorized investments within a defined buffer area of transit stations (1 mile for pedestrian projects, and 3 miles for bicycle projects) have been moved into the financially constrained Preferred Alternative, from the unprogrammed portion of the Preferred Alternative. This modification does not change the environmental analysis. The FEIS was conducted on the full Preferred Alternative, consisting of both constrained, and unprogrammed projects and investments. Also, the project list has been edited to remove projects that have been completed.
