Section 17E.060.440 Jetties, Groins, and Weirs

  1. Definitions.
    Jetties are elongated artificial obstructions projecting into a stream from the bank to control shoaling or scour by deflection of current. Groins are bank of shore-protection structures in the form of a barrier oblique to primary motion of water, designed to control movement of bed material. Weirs are structures in a stream or river for measuring or regulating stream flow.
     
  2. 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 publicly owned and/or maintained projects which do not degrade natural channel morphology or river processes, or cause adverse impacts to aquatic and terrestrial wildlife.
     
  3. Jetties, groins, weirs, and similar structures are allowed by a shoreline conditional use permit, except for those structures installed to protect or restore ecological functions, such as woody debris installed in streams.
     
  4. Jetties, groins, and weirs shall be designed to protect critical areas and shall provide for mitigation according to the sequence defined in SMC 17E.060.220.
