Activities for 2017

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 mapping and archaeological resources surveys. 

PSE and our contractors are now conducting utility mapping and archaeological resources surveys. For more information, please read our utility mapping survey flyer and our archaeological resources survey flyer.

Crews 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. Depending on property location, some surveys may not be needed.

For detailed surveys like the archaeological resources surveys and utility mapping surveys, PSE will notify property owners and tenants in advance of the survey beginning on their property. We will leave a door notification a few days in advance to notify you of the date range when we expect crews will be performing work on the property. On the day that fieldwork will occur on your property, PSE’s fieldwork crews will knock on your door to inform you that they will be working. For condos and apartments, we will work with homeowners’ associations and property managers regarding notification for planned fieldwork activities. 

If there is information you would like to pass along to our fieldwork crews related to your property (e.g., a locked gate or note about pets) please use our online form or call us at 1-800-548-2614, ext. 1. 

If you have other questions about fieldwork, please contact us by email at 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

Utility mapping surveys

PSE and our contractors are conducting utility mapping surveys on specific properties along the existing transmission line corridor. Our contractors Applied Professional Services (APS) and APS Survey & Mapping (APSSM) will locate and survey existing underground utilities at proposed pole locations and construction sites.

First, APS’ crew will locate the underground utilities and mark the ground with a biodegradable, non-toxic paint and/or flags. It is against the law to damage or remove these markings.

Survey crews from APSSM will then visit the property to survey and map utility locations. Our contractors may also use state-of-the-art ground-penetrating radar (GPR) to detect and map underground utilities in the corridor. This mobile GPR unit looks like a push mower.

Safety is our top priority. We want to ensure existing underground utilities are identified and considered in our design and construction plans and future permit submittals. For properties where no pole locations or construction sites are proposed, these utility mapping surveys may not be necessary.

Archaeological resources survey

PSE’s contractor Historical Research Associates (HRA) is conducting an archaeological resources survey along the existing utility corridor. HRA’s archaeologists are visiting 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, the 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.

Fieldwork already completed

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.

Earlier 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.
