About this file
This is a geographic information systems (GIS) map document prepared by Seattle City Light, Environment, Land and Licensing Business Unit, in support of the City of Seattle's Lower Duwamish Waterway (LDW) Polychlorinated Biphenyls (PCB) Sampling contract opportunity. The map identifies the primary testing area for transformer testing within the Duwamish Watershed using 2020 U.S. Census tracts. The document depicts multiple census tract boundaries in the area, untested transformer locations, the service area, and the broader watershed boundary (HUC8), with the Duwamish River prominently featured. The map was created on May 12, 2026, and supports the city's procurement process for PCB sampling services. Proposals for the LDW PCB Sampling project are due no later than 4:00 pm on Wednesday, August 26, 2026, with all questions to be submitted through the e-procurement portal at https://procurement.opengov.com/portal/seattle by 4:00 pm on Wednesday, August 19, 2026.
This map serves as a technical exhibit defining the geographic scope of the transformer testing project, which appears to be funded through a MegaToxins Grant. The primary testing area encompasses multiple census tracts within the Duwamish Watershed in Seattle, Washington. The document includes disclaimers that Seattle City Light provides no warranty regarding the accuracy, reliability, or completeness of the geographic data presented.
