The purpose of this appendix is to evaluate for the region as a whole and for each subregion the existing recreation resources and facilities, determine recreation needs, and outline framework plans to satisfy those needs in the foreseeable future for the water and related portion of outdoor recreation. Recreation values and needs are identified for the years 1970, 1980, 2000, and 2020. Major emphasis will be placed on the need for water-related outdoor recreation.

The purpose of Appendix X, Navigation, is to provide a broad picture of the important role water transportation has played in the economic development of the region, an inventory of existing waterway improvements and harbor facilities, projections of future needs and some general indication of measures that could be constructed to satisfy those needs. Measures to satisfy needs include all facets of navigation improvements required by commercial deep and shallow draft vessels and smaller fishing and recreational boats that ply the Pacific Ocean along the 500 miles of the region's coastal front, the 2,500 square miles of almost landlocked salt water comprising Puget Sound and adjacent waters, and the 2,880 miles of navigable rivers, lakes, and estuaries as defined by Act of Congress or court decisions or as designated by the U.S. Army Corps of Engineers.
