This section applies to all in-water and over-water structures and uses that facilitate water access or the launching or mooring of vessels, including all public and private docks, piers, marinas, mooring buoys, launch ramps and recreational floats. It does not apply to marine terminals and moorage structures, which are regulated in Section 14.50.590.

Construction of dock structures for the private noncommercial use of the owner, lessee or contract purchaser of single- and multifamily residences is exempt from the requirement for a shoreline substantial development permit pursuant to RCW 90.58.030(3)(e)(vii) and WAC 173-27-040(h). An HPA from the WDFW may still be required, as well as approvals from other agencies such as the United States Army Corps of Engineers (USACE).
