Congress Hall Sewer Pipe Stabilization Project

The Congress Hall Sewer Pipe Stabilization Project, managed by the West Valley Sanitation District, involves the emergency stabilization of a failing slope to protect a sanitary sewer line located at 21756 Congress Hall Lane in Saratoga, California. The primary scope of work includes the installation of a shear pin wall approximately 130 feet long on the downhill side of the sewer and a new support wall positioned about 10 feet below the existing iron fence. To mitigate environmental impact, the contractor must install temporary silt fences on the east and west sides of the property and implement erosion control through the planting of native vegetation upon completion. The project requires strict adherence to tree preservation standards, specifically avoiding the removal of healthy mature trees with a diameter of 12 inches or greater at breast height. Construction is anticipated to last eight weeks, with work performed Monday through Friday from 8:00 AM to 5:00 PM in compliance with the City of Saratoga Noise Ordinance. The contractor is responsible for implementing dust control measures, securing open excavations daily, and managing traffic control as mandated by the city. Additionally, residents must be notified at least two working days before work commences or resumes after a suspension of more than 24 hours. Alan Kam, Senior Civil Engineer, serves as the primary point of contact for this project, which is classified under NAICS code 237990.
