NOTES:

FindingIntent2014 c 56: "(1) The legislature recognizes that all Washington residents benefit from the unique aesthetic, recreational, and economic opportunities that are derived from the state's aquatic resources, including its navigable waters and shoreline areas. The legislature also recognizes that, as affirmed in chapter 212, Laws of 2011, existing floating homes are an important cultural amenity and an element of the state's maritime history and economy. The 2011 legislation, which clarified the legal status of floating homes, was intended to ensure the vitality and long-term survival of existing floating single-family home communities.
(2) The legislature finds that further clarification of the status of other residential uses on water that meet specific requirements and share important cultural, historical, and economic commonalities with floating homes, is necessary.
(3) The legislature, therefore, intends to: Preserve the existence and vitality of current, floating on-water residential uses; establish greater clarity and regulatory uniformity for these uses; and respect the well-established authority of local governments to determine compliance with regulatory requirements applicable to their jurisdiction." [ 2014 c 56 s 1.]
Finding2011 c 212: "The legislature recognizes that existing floating homes, as part of our state's existing houseboat communities, are an important cultural amenity and element of our maritime history. These surviving floating home communities are a linkage to the past, when our waterways were the focus of commerce, transport, and development. In order to ensure the vitality and long-term survival of these existing floating home communities, consistent with the legislature's goal of allowing their continued use, improvement, and replacement without undue burden, the legislature finds that it is necessary to clarify their legal status."
