Effective date- 2015 c 170 : "This act takes effect January 1, 2018." [2015 c 170 s 6.]
Findings-Intent- 2015 c 170 : "The legislature finds that flooding is a critical problem in Washington. The legislature further finds that flooding can result in loss of human life, damage to property, destruction of infrastructure, and bring economic activity to a standstill. The legislature further finds that flood control zone districts offer critical services that protect our state by mitigating the devastating impacts of flooding. It is the legislature's public policy objective to maximize available financing tools to flood control zone districts to continue their important work. Therefore, it is the legislature's intent to exempt levies imposed by a qualifying flood control zone district from certain limitations upon regular property tax levies." [2015 c 170 s 1.]
Application- 2015 c 170 : "This act applies to taxes levied for collection in 2018 and thereafter." [2015 c 170 s 5.]
