(1) Instream structures may be allowed only when the public benefits of such facilities clearly outweighs any loss of ecological processes and functions and only when an analysis of alternatives demonstrates that the proposed location and design would result in less adverse impact than alternative locations and designs.

(2) Breakwaters, jetties, groins, and weirs located waterward of the ordinary high water mark shall be allowed only where necessary to support water-dependent uses, public access, shoreline stabilization, or other specific public purpose. Breakwaters, jetties, groins, weirs, and similar structures shall require a conditional use permit, except for those structures installed to protect or restore ecological functions, such as woody debris installed in streams.

(3) Instream structures and associated facilities should provide for the protection and preservation of natural and cultural resources including, but not limited to, fish, wildlife and water resources, sensitive areas such as wetlands, sensitive geologic and geohydraulic areas and waterfalls, erosion and accretion shoreforms and natural scenic vistas.

(4) Careful consideration should be given to avoiding or minimizing land and water use conflicts to properties in shoreline jurisdiction and to properties both adjacent to, upstream and downstream of the proposed site.

(5) All instream structures should be designed to permit natural transport of bed load materials.

(6) Instream structures and their support facilities should be designed to minimize removal of riparian vegetation and the necessity for shoreline stabilization structures.

(7) Mitigation shall be required for loss of fisheries and wildlife resources, natural systems including wetlands and sensitive areas. No net loss in function or value of acreage should occur as a result of instream structures. When required, mitigation measures should be properly planned and monitored to ensure their effectiveness.

(8) Instream structures and associated facilities shall be located and designed so they do not interfere with public navigation of the watercourse including commercial and recreational navigation. Such uses include barging, rafting, sailboarding, kayaking and canoing.

(9) Instream structures and associated facilities should not be located where they will adversely impact publicly owned lands or waters used extensively for recreation. Impacts that should be avoided include the visual impact of the structure or facilities, the intrusion of roads or utility corridors into undeveloped area used for recreation, reduced water noise and significant visual impacts from reduced water flows.

(10) Instream structures shall be designed and constructed to ensure public access to and along the shoreline, in accordance with the public access policies and regulations contained in this SMP. Existing public access and recreational opportunities should be retained, enhanced or replaced. (Ord. 1373 § 46, 2014).
