Kittitas County Shoreline Master Program Chapter 6 129 March 7, 2016 Kittitas County Board of County Commissioners Shoreline Master Program Adopting Ordinance Kittitas County Shoreline Master Program Exhibit A | March 2016 | Page 129 of 339 7. Viewpoints, parking, trails and similar improvements should be considered for inclusion in transportation system projects in shoreline areas. 8. Public transportation routes should be located, designed, and maintained to provide safe enjoyment of adjacent shoreline areas. B. Regulations 1. Roads and railroads shall not be located within a designated shoreline except where it is necessary to cross a stream corridor, or where an existing use, development, topography, and other conditions preclude locations outside the shoreline. a. Construction of roadways across stream corridors shall be by the most direct route possible having the least impact to the stream corridor. b. Roadways that must run parallel to stream or wetland edges shall be along routes having the greatest possible distance from stream or wetland and the least impact to the corridor. c. Roadways within the stream corridor shall not hydrologically obstruct, cut-off, or isolate stream corridor features. 2. Material excavated from the roadway area to achieve the design grade shall be used as fill where necessary to maintain grade, or shall be transported outside the shoreline. 3. Necessary fill to elevate new roadways shall not impede the normal flow of floodwaters or cause displacement that would increase the elevation of flood waters such that it would cause properties not in the floodplain to be flood-prone. 4. Spoil, construction waste, and other debris shall not be used as road fill or buried within the shoreline. 5. Bridges and water crossing structures shall not constrict the stream channel or impede the flow of the ordinary high water, sediment, and woody debris. 6. Natural stream channels and drainage ways shall be preserved through the use of bridges for crossings, unless the use of culverts is demonstrated to be the only technically feasible means for crossing. The use of bridges shall be the preferred means to preserve natural streams and drainage ways. Where bridges are not feasible, large, natural bottom culverts, multi-plate pipes and bottomless arches shall be used. 7. The alignment and slope of culverts shall parallel and match the natural flow of streams or drainage ways, unless doing so conflicts with subsections 1 and 2 above, and shall be sized to accommodate the OHWM, sediment, debris and ice.
