Survey work in the Coal Creek Sewer Upgrade Project area beginning this month 

As King County’s Coal Creek Sewer Upgrade Project moves into construction, early field activity will begin soon.  

The County’s contractor will survey multiple work areas, including the Coal Creek Natural Area, a utility right of way that will be used for staging, and more. The contractor’s survey activity is expected to begin in late March and take 8 weeks.  

Before the contractor begins their pre-construction survey, King County Wastewater Treatment Division’s Mitigation and Monitoring team will perform a routine annual survey of the existing Coal Creek pipe alignment. These surveys help us monitor how the creek and environment around our pipe changes over time. This work is expected to begin March 14 and take up to 3 days.  

We will continue to monitor restored work locations in the Natural Area after construction for the duration of King County’s permits (expected to be 10 years). In addition, we will monitor decommissioned sections of pipe into the future.

What to expect?

• Work hours are from (7am to 4pm, Monday to Friday)  
• For the survey of the area around the existing pipe, visitors to the Natural Area may see people wearing reflective vests and hard hats around the Coal Creek Trail, by the creek, or in forested areas.  
• The contractor’s survey will extend over 8 weeks and will involve multiple work areas.
