(1) Local utility services needed to serve water-dependent and other permitted uses in the shoreline are subject to standards for ecological protection and visual compatibility.

(2) Utility systems designed to primarily serve utility demand of the larger region shall be located outside of SMA jurisdiction, to the extent feasible, except for crossings of water bodies and other elements of shorelands by linear facilities which shall cross in a perpendicular alignment minimizing disturbance.

(3) Linear facilities consisting of pipelines, sewers, cables and other facilities roughly parallel to the shoreline shall be discouraged except where no other feasible alternative exists. When permitted, design shall assure that maintenance of the facilities does not result in a net loss of shoreline ecological functions or significant impacts to other shoreline resources and values. At the time of replacement of such facilities that are close to their lifespan, or when such facilities are expanded, consideration shall be given to relocating outside of the shoreline as if they were new facilities.

(4) Utility crossings of water bodies shall be attached to bridges or located in other existing facilities, if reasonably feasible. If new installations are required to cross water bodies or wetlands they should avoid disturbing banks and streambeds and shall be designed to avoid the need for shoreline stabilization. Crossings shall be tunneled or bored where reasonably feasible. Installations shall be deep enough to avoid failures or need for protection due to exposure resulting from stream bed mobilization, aggregation, or lateral migration. Underwater utilities shall be placed in a sleeve if reasonably feasible to avoid the need for excavation in the event of the need for maintenance or replacement.

(5) New electrical distribution lines within the shoreline shall be placed underground. Distribution lines that cross water or other critical areas may be allowed to be placed above ground if:

(6) Utility transmission lines shall be underground or underwater when economically feasible and where not significantly detrimental to the environment. Underground utility lines shall be bored where feasible and placed at an appropriate depth under the river bed in all river or stream crossings except where such lines are permanently affixed to a bridge structure.

(7) Utility rights-of-way shall be managed for compatible multiple uses such as shore access, trails, and recreation whenever possible. Utility right-of-way acquisition should be coordinated with transportation and recreation planning. New utility corridors, or expansion of facilities on existing corridors, shall provide public access in accordance with SMC 17.150.025. Utilities shall be encouraged to provide pedestrian public access on existing utility corridors. Critical area impacts should be avoided and if they are not then these impacts will need to be mitigated.

(8) Stormwater management facilities, including detention/retention/treatment ponds, vaults, media filtration facilities, and lagoons or infiltration basins, may be permitted within SMA jurisdiction if:

(9) Stormwater, wastewater, or water supply pump stations, and stormwater discharge facilities such as dispersion trenches, level spreaders, and outfalls, may be located in the shoreline jurisdiction if:
