Can I replace the bulkhead along the lake? |
Any type of bulkhead repair or construction is referred to as shoreline stabilization. Shoreline stabilization includes a wide range of activities to control erosion or to prepare shorelines for development. Stabilization generally employs hardened structures, built parallel to the shoreline, that protect soils and unstable banks from the action of currents and waves. Common stabilization methods include revetments, bulkheads, and seawalls. The Department of Ecology's Shoreline Stabilization guide provides information on best practices for protecting the ecology along the lake shores. |
Where is the Ordinary High Water Mark? |
The Ordinary High Water Mark (OHWM) is the mark on all lakes where the presence of water marks the soil and vegetation with a distinct character. The OHWM varies from place to place and can move up or down in elevation over time. Cities around the lake including Bellevue, Issaquah, and Sammamish have determined the local OHWM to be somewhere between 28.0 and 28.2 feet NGVD29. However, an OHWM location may need to be determined by an environmental professional, based on the scope a project. More information is provided by the Department of Ecology on the Ordinary High Water Mark webpage. |
How do I know where my property lines are in the water? |
How to locate property lines that extend into the water (also referred to as "lateral lines") is not straight-forward. General information is referenced in the article Waterfront Titles in the State of Washington, by the Chicago Title Insurance Company. |
What can I build in my yard, between my house and the water? |
From the Ordinary High Water Mark (OHWM), there is a 50-foot shoreline setback for Lake Sammamish and a 45-foot shoreline setback for Beaver Lake and Pine Lake. On Lake Sammamish, this area in intended to have a portion along the shoreline reserved for native vegetation that provides habitat and contributes to ecosystem of the lake. For all lakes, very limited development may be allowed. Please submit for Project Guidance for more information. |
