Slope Stability & Landslide Risk Assessment

The contract involves conducting detailed analyses of natural and man-made slopes within park areas to evaluate their stability and assess risks associated with landslides in vulnerable zones. The work requires specialized engineering expertise to identify potential failure mechanisms, evaluate soil and geological conditions, and determine the likelihood of slope instability under various environmental conditions. The successful bidder will be responsible for delivering comprehensive landslide risk assessments that inform decision-making for public safety and infrastructure protection. Mitigation measures must be proposed based on technical findings, including but not limited to drainage improvements, slope regrading, retaining structures, vegetation management, or monitoring systems. All recommendations must align with local geotechnical standards and prioritize durable, cost-effective solutions that reduce long-term risks to park visitors and surrounding communities. The solicitation is issued as a subcontract under NAICS code 541610 by the City of Issaquah in Washington, with proposals due by August 14, 2026, and performance expected to occur within the designated park areas under the city’s jurisdiction.
