You may be remembering the 2010 “levy lid lift,” which was about library operations and services, not a library building.  In 2010 citizens county-wide voted to restore NOLS’ operating levy, which had eroded over time to 33¢/$1000 of Assessed Valuation, to the 50¢/$1000 originally approved in 1978.  The 2018 Sequim LCFA vote is specifically about funding a new branch library building in Sequim, and only voters living in the area served by the Sequim Branch Library will have the opportunity to vote.
