Shoreline Master Program Update

The City of Seattle’s Shoreline Master Program (SMP) is being comprehensively updated for the first time since 1987. The SMP constitutes the policies and regulations governing development and uses on and adjacent to marine and freshwater shorelines. This includes the waters of Puget Sound, Lake Washington, Lake Union/ Ship Canal, Duwamish River, Green Lake, as well as associated wetlands and floodplains. These policies and regulations affect land uses, structure bulk and setbacks, public access requirements, bulkheads, docks, piers, and construction practices.

Stormwater, Grading and Drainage Code Revisions

The Stormwater, Grading and Drainage Control Code (SMC 22.800-22.808) and associated Directors’ Rules are being revised to account for advances in urban stormwater runoff management practices. These regulations are in place to protect life, property, public health and the environment from the adverse impacts of urban stormwater runoff. Adverse impacts can include flooding, pollution, landslides and erosion.
