1. Aquatic Marine applies to all Puget Sound tidal waters. Tidal waters, as used here, includes marine and estuarine waters bounded by the OHWM. Where a stream enters the tidal water, the tidal water is bounded by the extension of the elevation of the marine OHWM within the stream.

2. Aquatic Freshwater applies to the waters of all rivers, streams and lakes.

1. All development on navigable waters and submerged lands should be located and designed to minimize interference with surface navigation, to reduce impacts to public views, and to allow for the safe, unobstructed passage of fish and wildlife, particularly those species dependent on migration.

2. Development that adversely impacts the ecological functions of marine and freshwater habitats should not be permitted except where necessary to achieve the objectives of RCW 90.58.020, and then only when all identified impacts are mitigated as necessary to assure maintenance of shoreline ecological functions and processes.

3. Shoreline development and modifications should be designed and managed to prevent degradation of water quality and alteration of natural hydrographic conditions.

4. New over-water structures should only be permitted for water-dependent uses or public access. The size of new over-water structures should be limited to the minimum necessary to support the structure's intended use.

5. Multiple uses of the same over-water facility should be encouraged.

6. Overwater linear public transportation and utility facilities may be allowed when it is the most technically, economically, and environmentally feasible option.
