Fieldwork

Activities for 2017

Beginning this spring, PSE and our contractors are conducting additional fieldwork surveys to help us refine our design and inform future permit submittals. You may see crews visiting properties along the existing transmission line corridor and conducting utility and archaeological resources surveys. 

PSE and our contractors will conduct fieldwork Monday through Friday, typically between 8 a.m. and 5 p.m. Our fieldwork crews will have a letter verifying they are under contract with PSE and are authorized to conduct surveys.

For detailed surveys, like the archaeological resources surveys, PSE will notify property owners and tenants in advance of the survey beginning on their property. Stay tuned for details! 

If you have questions about fieldwork, please contact us by email at energizeeastside@pse.com or by calling our fieldwork information line at 1-800-548-2614 ext. 1.


PSE began collecting field information in 2015 to inform the environmental review process, as well as project design and future permit submittals for the Energize Eastside project. 

Upcoming fieldwork

Archaeological resources survey

Later this spring, PSE’s contractor Historical Research Associates (HRA) will conduct an archaeological resources survey along the existing utility corridor. HRA’s archaeologists will visit properties to assess the potential presence of artifacts and/or features more than 50 years old. Some examples of these resources include prehistoric stone tools and historic-period metal and glass items.

This survey is part of the permitting process. PSE, Washington State Department of Archaeological and Historic Preservation (DAHP), and other government agencies will use data collected to identify and document potential sites and artifacts of historic and cultural significance. Archaeologists will walk each property looking for the presence of these resources. 

For properties where poles and/or construction sites are proposed, archaeologists will conduct a “shovel probe” by digging shallow holes to identify artifacts or evidence of past human activities. HRA will fill the holes prior to departing each property. PSE will notify individual property owners in advance of beginning this survey.

Completed fieldwork

In 2015, PSE crews and industry experts completed multiple surveys to investigate on-the-ground characteristics of a particular location, including:

  • Land surveys to help identify the precise locations of property lines, sidewalks, driveways, fences, corners of buildings, both underground and overhead utilities, and other property features.
  • Wetland delineation surveys to identify, classify and record the location and boundaries of environmentally sensitive areas (e.g., wetlands, creeks and floodplains). 
  • Inventory of trees along and near the proposed routes to collect data on tree height, diameter and species.
  • Geotechnical investigations at specific locations along the routes to identify soil types in and around proposed pole locations. Certain soils provide better conditions for pole foundations than others. 
  • A pipeline co-location study to help PSE determine where the upgraded transmission poles could be located adjacent to the Olympic pipeline. Crews tested the soil to ensure the safe co-location of PSE's potential future poles and the Olympic pipeline's existing facilities.

In 2017, PSE and our contractor, Historical Research Associates (HRA), completed an architectural survey of properties along the existing utility corridor and in the Factoria area. This was an observational survey conducted from sidewalks and other public rights of ways to understand the historic character and significance of buildings and structures along the Energize Eastside route options.
