City explains beneficial‑reuse practice for excavated soil; says testing and worker protections are used
Summary
Utilities staff said the material the city used for dam maintenance is often urban fill reused for embankments, that visual checks and occasional testing govern reuse, and that staff take PPE and containment measures to minimize worker exposure.
Rob Schultz explained the city's practice of beneficial reuse: when material from street excavations or emergency repairs meets visual criteria it is processed and reused for embankment maintenance rather than shipped to a landfill. Schultz said that, absent visual signs such as sheen, smell or texture indicating industrial contamination, crews reuse native urban fill and limit disturbance to minimize dust and worker exposure.
Schultz acknowledged gaps in permanent disposal options after the city lost a primary yard and described a temporary sublease yard on Allesley Street where some soil is being staged and processed. He said the utility pauses or removes material if a regulatory partner flags contamination and that larger removals to certified landfills occur if testing indicates hazardous constituents.
Why it matters: residents worried dumping could leach contaminants into wetlands or drinking‑water infrastructure; staff said the main hazard is to workers handling material and that the regulated water‑treatment process protects drinking supplies.
Next steps: staff will continue limited reuse practices while pursuing safer long‑term solutions and will coordinate with regulators about testing requirements and disposal.
