30.67.590 Transportation, circulation and parking.
(1) The following general regulations apply to facilities and structures for transportation, circulation and parking within shorelines:
(a) New transportation facilities may be located within shoreline jurisdiction only when alternative locations are not feasible.
(b) Transportation facilities shall cross shoreline jurisdiction by the most direct route feasible, unless such a route would result in greater impacts on wetlands and fish and wildlife habitat conservation areas, agricultural activities, or channel migration than a less direct route.
(c) Transportation facilities shall be designed to allow the free flow of water, sediment and debris under them and to convey a 100-year flood without causing any rise in the flood profile above conditions at the time of permit application. All bridges must provide a minimum of three feet of clearance above the one hundred year flood level.
(d) Transportation facilities that cross over watercourses or wetlands shall utilize elevated, open pile or pier structures whenever feasible.
(e) Road crossings on fish-bearing streams shall be designed according to the guidelines set forth in Fish Passage Design at Road Culverts (Washington Department of Fish and Wildlife, March 3, 1999).
(f) Bridge approach fills shall not encroach in the floodway of the base flood (100-year frequency) of any river.
(g) When transportation facilities are designed to act as flood control structures, the proposal shall comply with the requirements of SCC 30.67.540.
(h) New and enlarged transportation facilities shall provide public access pursuant to SCC 30.67.330.
(i) Circulation system plans should include provisions for pedestrian, bicycle and public transportation where appropriate.
(j) Parking and loading facilities necessary to support an authorized shoreline use may be allowed in shoreline areas only when:
(i) The applicant can demonstrate that no other alternative location is feasible to serve the primary use of the site; or
(ii) The parking or loading facility is needed to accommodate public access pursuant to the Americans with Disabilities Act (ADA), 42 U.S.C. § 12101 et seq.
(k) All of the following conditions shall be met when a parking facility is proposed in the shoreline jurisdiction:
(i) The facilities shall be located landward from the primary building or use being served, except when the parking facility is within or beneath the structure and adequately screened;
(ii) Shoreline stabilization measures will not be necessary to protect the facility;
(iii) The facility will not result in impacts to wetlands and fish and wildlife habitat conservation areas and their functions and values or the impacts can be mitigated in accordance with the requirements of chapter 30.62A SCC;
(iv) Upland parking facilities shall provide safe and convenient pedestrian circulation from the parking area to the shoreline;
(v) Loading spaces for development in the shoreline jurisdiction shall be located on the landward side of nonwater-dependent uses or activities; and
(vi) All facilities shall provide parking suitable to the expected usage of the facility in accordance with parking requirements in Title 30 SCC.
(2) In addition to the general regulations contained in SCC 30.67.590(1), the following shoreline environment designation-specific regulations for transportation, circulation and parking apply:
(a) Bridges, roads and parking facilities are permitted in the Urban, Rural Conservancy and Resource environments;
(b) Bridges, roads and parking facilities are conditionally permitted in the Urban Conservancy and Municipal Watershed Utility environments, except that roads and bridges constructed for forest practices in accordance with Title 222 WAC are permitted in the Municipal Watershed Utility environment.
(c) In the Natural environment:
(i) Bridges and roads are prohibited; and
(ii) Parking facilities are conditionally permitted.
(d) In the Aquatic environment:
(i) Bridges are conditionally permitted, provided they are permitted or conditionally permitted in the adjacent upland environment, except that bridges constructed for forest practices in accordance with Title 222 WAC are permitted in the Aquatic environment provided that the adjacent environment is not designated as Natural; and
(ii) Roads and parking facilities are prohibited. (Added by Amended Ord. 12-025, June 6, 2012, Eff date July 27, 2012).
