Sammamish: Tightline Project

The City of Sammamish is currently undertaking the significant "Tightline Project" on Louis Thompson Road, a vital connection route that exemplifies the city's commitment to strategic urban development and enhanced community infrastructure. This comprehensive upgrade represents a forward-looking investment, primarily aiming to address long-standing issues of uncontrolled stormwater runoff, which has historically posed significant challenges to the city's environmental integrity and public safety through erosion, flooding, and potential landslide risks. Beyond mitigating these critical environmental concerns, the project is a cornerstone in the city's broader vision to enhance urban connectivity and ensure the well-being of its residents through crucial non-motorized improvements.
