<br /> <br />42 <br /> <br />a. The dock or ramp is located and oriented and constructed in a manner that <br />minimizes adverse effects on water quality, movement of aquatic and terrestrial life, <br />ecological processes, spawning habitat, and wetlands; <br />b. Docks and ramps shall meet or exceed all relevant state and federal permit <br />requirements; and <br />c. No adverse impact to fish or wildlife habitat areas or associated wetlands will occur. <br />4. Roads, trails, bridges, and rights-of-way. Construction of trails, roadways, and bridges <br />through or across streams, other fish and wildlife habitat conservation areas and/or their <br />RMZs or buffers are subject to all the following, and those standards described in WDFW’s <br />Water Crossing Guidelines and KCC 17A.01.120.4: <br />a. There is no other feasible alternative route with less impact on the fish and wildlife <br />habitat conservation area; <br />b. The crossing minimizes interruption of downstream movement of wood, ice, <br />sediment, and the movement of all fish and wildlife. Bridges are preferred for all <br />stream crossings and should be designed to maintain the existing stream substrate <br />and gradient, provide adequate horizontal clearance on each side of the ordinary <br />high water mark, and provide adequate vertical clearance above the ordinary high <br />water mark; <br />c. Roads within a stream buffer shall not run parallel to the water body when there is an <br />alternative alignment that has less adverse effect on stream functions; <br />d. Trails shall be located on the outer edge of the fish and wildlife habitat conservation <br />area buffer, except for limited viewing platforms and at the crossing, and shall use <br />pervious materials where feasible; <br />e. Stream crossings, where necessary, shall be perpendicular with the stream, or as <br />close to perpendicular as possible, and shall be the minimum width necessary. <br />Common or shared crossings are the preferred approach where multiple properties <br />can be accessed by one crossing; and <br />f. Culverts and bridges shall be designed according to applicable state and federal <br />guidance criteria for fish passage as identified in Fish Passage Design at Road <br />Culverts, WDFW, 2003, and/or the National Marine Fisheries Services Guidelines for <br />Anadromous Salmonid Passage Facility Design, 2011, (and subsequent revisions) or <br />WDFW’s Water Crossing Design Guidelines (WDFW, 2013). The applicant or <br />property owner shall maintain fish passage through the culvert. <br /> <br />5. Utility facilities. New utility lines and facilities may cross streams or Fish and wildlife habitat <br />conservation areas if they comply with the following standards, and those standards <br />described in KCC 17A.01.120.4: <br />a. There is no other feasible alternative route with less impact on the Fish and wildlife <br />habitat conservation area; <br />b. Installation at a stream crossing shall be accomplished by boring beneath the scour <br />depth and hyporheic zone of the stream and the entire channel migration zone width, <br />where feasible; <br />c. Where boring under the channel is not feasible. the utilities shall cross at an angle of <br />no less than sixty (60) degrees, but as close to ninety (90) degrees as possible, <br />relative to the centerline of the channel; <br />d. Crossings shall be contained within the footprint of an existing road, bridge or utility <br />crossing where possible; <br />e. The utility route shall avoid paralleling the stream or following a down-valley course <br />near the channel; and <br />f. The utility installation shall not increase or decrease the natural rate of channel <br />migration.
