This project remediates soils contaminated with arsenic from operations of the former Asarco Smelter, at twenty-six (26) single-family residential properties in north Everett, Snohomish County, Washington, shown in the Contract Drawings. All work is outdoors. Work at each property typically includes implementing temporary construction controls for environmental protections, selective demolition or temporary removal of site features, excavating soils contaminated with arsenic; disposing of excavated soils at an approved landfill; importing clean fill material; backfilling with imported material, compacting, and grading; restoring properties to preconstruction conditions; and landscape and lawn restoration and maintenance, all in accordance with the requirements of the Project Manual.
