of housing. Ridership declines also coincide with passage of AB 60, signed into law by Governor Brown in 2013, which provides for issuance of a vehicle operators license regardless of immigration status. The fiscal changes are the passage of Measure R, a countywide incrememental sales tax increase passed by voters in 2008, provides funding for many of the highest priority projects in the LRTP. On November 6, 2012, Metro attempted to pass Measure J, but failed as it did not reach the two-thirds majority needed to pass. In November 2016 election, Metro decided to place another sales tax on the ballot. The voters then approved Measure M, a half-cent permanent sales tax increase, to fund many local projects, including Metro Rail expansion. In 2018, Metro approved renaming its rail lines using a letter-based scheme, similar to those in New York City. Metro recommended the opening of the refurbished A Line in 2019 as a starting point to rename the lines, and then continuing with the opening of the K line, finishing in time for the opening of the Regional Connector in 2022. Current and priority projects The following rail projects have been given high priority by Metro. They all appear in the 2009 LRTP constrained plan, and all have funding earmarked from Measure R. With the passage of Measure M in 2016, Metro released an updated Long Range Transportation plan in February 2017, and released a full report in 2020, along with its Twenty-eight by '28 initiative. Other expansion concepts Metro's Long Range Transportation Plan was published in 2009, and was updated by in 2020. The following proposed line/system expansions do not have funding or high priority in Metro's long-range plans. Some are listed as "strategic unfunded" in the last Long Range Transportation Plan, indicating some possibility they could be constructed should additional funding materialize. Others have been the subject of Metro Board discussion, with the possibility of future feasibility studies. (More information on each project can be found in the references.)
