Congress Hall Sewer Pipe Stabilization Project

The West Valley Sanitation District is undertaking an emergency stabilization project at 21756 Congress Hall Lane in Saratoga, California, to prevent imminent failure of a sanitary sewer line due to active slope movement. The primary solution involves constructing a shear pin and tie beam wall approximately 130 to 200 feet long downslope of the existing sewer, embedded below the active landslide zone, with work restricted to disturbed areas on the roadway and vineyard while preserving all healthy mature trees with a diameter of 12 inches or greater at breast height. The project qualifies as an emergency under CEQA §15269 due to the imminent threat to public health and safety from potential raw sewage release, allowing for a non-competitive, expedited procurement process without a formal solicitation number. Construction is planned for an eight-week period between 8 a.m. and 5 p.m., Monday through Friday, beginning in fall 2025, with all activities strictly complying with the City of Saratoga’s noise ordinance, dust control requirements, and erosion mitigation standards. Contractor responsibilities include installing temporary black geotextile silt fences on both the east and west sides of the work area to prevent debris migration, restoring all disturbed soil with native vegetation upon completion without the use of drip or artificial irrigation, and ensuring all excavations are properly barricaded and covered at the end of each day. Traffic control measures such as signage, barricades, and flagpersons must be implemented per local regulations, and pollution control efforts must be coordinated with other ongoing activities. No formal contract type, pricing, payment details, or federal acquisition regulations such as FAR clauses, packaging standards, or representation certifications are specified, reflecting the municipal emergency nature of the procurement. The West Valley Sanitation District retains full inspection and acceptance authority at the project site, with oversight led by Senior Civil Engineer Alan Kam. The work is governed by state environmental compliance and local ordinances, with no federal military or defense-related standards referenced, and all requirements are focused on rapid, environmentally responsible stabilization to mitigate immediate risk of infrastructure failure.
