About this file

Written by GovTribe AI · May 11, 2025

These detailed engineering design plans are prepared by Geo-Logic Associates for the Sacramento County Department of Waste Management and Recycling, specifically for the Module 4, Phase 2 Base Liner System and Module 1, Phase 4 and 5 Final Cover at the Kiefer Landfill. The comprehensive set of technical drawings (28 pages) covers the design and specifications for landfill base liner and final cover construction, including detailed site plans, base liner subgrade plans, ballast system and operations layer plans, erosion control plans, liner system details, and specific technical configurations for drainage, piping, and geosynthetic layering. The plans are dated August 17, 2022, and are marked "Issued for Construction", indicating they are the final engineering documents ready for implementation.

The project involves complex landfill engineering with multiple technical components, including geomembrane liners, drainage systems, leachate collection and removal systems (LCRS), geosynthetic clay liners, aggregate base layers, and erosion control measures. The design incorporates sophisticated engineering techniques such as textured geomembranes, perforated piping systems, geotextile filters, and specialized slope stability features. The plans show intricate details for connecting new liner systems to existing modules, with careful attention to slope grades, drainage channels, and interface between different project phases. The technical specifications suggest a comprehensive approach to environmental protection, waste management infrastructure, and long-term site stability, with precise engineering solutions tailored to the specific topographical and geological conditions of the Kiefer Landfill site in Sacramento County.
