Shoreline Master Program

What Is It?

The Shoreline Master Program (23.60A) regulates development in the city’s shoreline environments to:

  • Protect shoreline ecosystems
  • Respond to pollution discharges into bodies of water
  • Encourage water-dependent uses
  • Provide for maximum public use and enjoyment of the shorelines
  • Preserve, enhance, and increase views of and access to the water

Proposed Changes

To help explain the permitting requirements and process for replacing a floating on water residence or house barge, SDCI has drafted Tip 229A, Shoreline Permitting Requirements for Floating on Water Residences (FOWR) and House Barges. Please see below for a link to review this document.

Additionally, SDCI is amending the definition of "vessel" in the Shoreline Master Program to address a Seattle Hearing Examiner's decision that ruled that an existing vessel with a broken engine is not a vessel. The SEPA determination for this proposed amendment is now available and links to the decision and supporting documents are included below. We're accepting public comments through July 30, 2018; see the SEPA notice for instructions on how to comment.
