Description
Construction of a CCR landfill within steep geography presents unique challenges related to stormwater management, erosion control, and establishing placement and compaction practices over an extended construction timeline. This presentation builds upon prior work focused on temporary rain cover and wet-weather resiliency, expanding the discussion to practical strategies implemented during the prolonged startup and subsequent phases of waste placement. Key topics include: Stormwater management during active construction, with emphasis on intercepting, conveying, and controlling runoff in a topographically constrained setting. Breaking up drainage areas to reduce flow concentrations, prevent channelized erosion, and improve maintainability as grading evolves. Erosion control approaches in the realities of steep slopes, limited working area / widths, and continual regrading during placement operations. Placement and compaction challenges, including managing moisture content, maintaining equipment access, and sequencing fill to minimize storm impacts while meeting structural requirements. Together, these elements illustrate a coordinated approach to managing stormwater and erosion risks while advancing CCR placement in demanding geometric and topographic environments. The case study highlights lessons learned, design adaptations, and best-practice techniques that would be applicable to similar steep-valley landfill projects and provides the designer and owner perspective through construction/operation.
