Concerning boundary line adjustments on public lands owned or managed by the department of natural resources.
Senate Bill 5170 establishes new procedures for the Department of Natural Resources (DNR) when conducting land surveys or adjusting boundary lines on public lands it owns or manages, directly affecting adjoining private landowners. The bill requires the DNR to provide written notification to affected landowners within 30 days regarding proposed boundary markers or before undertaking specific surveys. It also mandates that DNR offer landowners an opportunity to review, comment, present historical evidence, and be involved in decisions about proposed boundary locations or adjustments. Additionally, the DNR must comply with these notification and involvement requirements before it can initiate a lawsuit to resolve a property boundary dispute.

MODERATE
The bill was renumbered and its title was updated to reflect 'boundary line surveys' instead of 'boundary line adjustments.' The primary substantive change adds an exemption for aquatic lands, meaning the new notification and public comment requirements now only apply to surveys on dry land. Additionally, the requirement for the department to notify landowners was changed from a general notice to a specific 'written' notice directed at 'adjoining' landowners.
Scope change
The bill's scope was narrowed by excluding aquatic lands from the new notification and comment requirements.
REQUIREMENT
Added an exemption for aquatic lands, restricting the new notification and public comment rules to surveys on lands other than aquatic lands.
Changed the notification requirement to mandate that the department must provide 'written' notice specifically to 'adjoining' landowners.
DEFINITION
Added a specific reference to RCW 79.02.010 to define what constitutes 'aquatic lands' for the purpose of the exemption.
TECHNICAL
Updated the bill number from S-0204.2 to S-0807.3 and changed the title from 'boundary line adjustments' to 'boundary line surveys.'
