(1) Recognizing the large number of physical variables to be considered in properly locating and designing in-stream and in-water structures, and the high probability that poorly located and inadequately designed structures will fail and/or adversely impact properties and shore features, such structures should be sited and designed by the project proponent consistent with appropriate engineering principles and guidelines of the Natural Resources Conservation Service, the U.S. Army Corps of Engineers, and the Washington Department of Fish and Wildlife.

(2) Project proponents shall give due consideration to the full range of public interests, watershed functions and processes, and environmental concerns, with special emphasis on protecting and restoring priority habitats and species when locating and planning in-stream and in-water structures.

(3) In-stream structures should be planned and designed to be compatible with navigation and recreation, especially in shorelines of statewide significance, provided that public safety and ecological protection are fully addressed.

(4) Proposals for new in-stream and in-water structures should be evaluated by the Administrator for their potential adverse impacts on the physical, hydrological, and biological characteristics as well as effects on species that inhabit the shoreline, riparian area, or nearshore area.

(5) The County should review proposals for new in-stream/in-water developments to determine if any such development would thwart or substantially compromise planned restoration actions. The County should work with the proponents of each project to resolve likely conflicts between residential development and planned restoration.
