It is the intent of the legislature that the proceeds of the new bonds authorized in RCW 43.99G.160 will be appropriated in phases over five biennia, beginning with the 2005-2007 biennium. This is not intended to limit the legislature's ability to appropriate bond proceeds if the full amount authorized in RCW 43.99G.160 has not been appropriated after five biennia. The authorization to issue bonds contained in RCW 43.99G.160 does not expire until the full authorization has been appropriated and issued.
