I just did a nice, little review of the political reporters work over at Clark County's newspaper and it seems she missed a piece of legislation of Ann Rivers and Don Benton (along with some other co-sponsors?) have a piece of legislation, senate bill 5088, that would in essence elimiate a lot of wording in RCW 81.104 to the reference of "High Capacity Transit" and associated wording, that looks like it was eliminated to clean up the section:
(as of January 22, 2013, this is the current version) src: http://apps.leg.wa.gov/documents/billdocs/2013-14/Pdf/Bills/Senate%20Bills/5088.pdf
And the bill's digest suggests this is the apparent reason for the bill:
"Gives all eligible voters within the boundaries of a
transit agency the opportunity to vote on the transit agency's
plan to raise revenue for the purpose of creating a high
capacity transportation system."
and can be found at src: http://apps.leg.wa.gov/documents/billdocs/2013-14/Pdf/Digests/Senate/5088.DIG.pdf
