About this file
This is an as-built documentation file for the Kiefer Landfill base liner system maintained by the County of Sacramento, Department of Waste Management & Recycling. The document provides a comprehensive technical summary of liner system components installed across multiple modules and phases of the facility from November 1993 through February 2024. The table details specifications for eleven separate construction projects, including general contractors, liner installers, construction dates, and acreage of coverage for each phase. Key components documented include operations layers, drainage layers, geomembranes, geotextiles, geosynthetic clay liners, and leak detection systems. The liner systems have been installed by various firms including Serrot, Geo Pacific, GSI United Linings, National Seal, C.W. Neal Corp, D&E Construction Inc, Layfield Geosynthetics, and others. Construction activities span from the initial Phase 1 of Module M1L (15.5 acres, November 1993) to the most recent Phase 1 of Module M4 (27 acres, February 2024), with total documented installation area exceeding 168 acres.
The document reflects evolving engineering standards and material specifications over three decades of landfill development. Early phases utilized single-sided textured HDPE geomembranes and basic drainage configurations, while later phases incorporated more sophisticated systems including double-sided textured geomembranes, leak detection system geocomposites, and geosynthetic ballast systems for wind protection. Materials specified include products from manufacturers such as Gundle, CETCO, GSE, Solmax, and Agru America. Low-permeability soil layers consistently feature hydraulic conductivity requirements of K < 1x10-7 cm/s or better, with geosynthetic clay liner components rated at K < 2x10-9 to K < 5x10-9 cm/s. Quality assurance firms listed include Floor Slope Material, EMCON, Shaw Environmental Inc, Golder Associates Inc, and Geo-Logic Associates. This documentation serves as a baseline record for the facility's environmental protection infrastructure and is directly referenced in the related on-call repair services contract solicitation.
