Some parts of Capitol Lake to close for geotechnical survey drilling

The geotechnical survey marks a crucial phase in the ongoing efforts to restore the Deschutes Estuary


The Department of Environmental Services (DES) is set to conduct a geotechnical survey around Capitol Lake as part of the Deschutes Estuary Restoration Project.

The survey work includes drilling into the ground to collect essential samples and started Monday, Dec. 18. The hours of the work to run is between 7 a.m. and 5 p.m. and is expected to wrap up on Friday, Dec. 22.

Due to this survey, visitors to Heritage Park and those passing Deschutes Parkway Southwest around the perimeter of Capitol Lake, extending just past the Olympic Street West intersection, should be aware of visible changes.

Large machinery, trucks, and crews will be on-site, and the drilling process is expected to generate noise.

Pedestrians planning to enjoy the walking path are advised that a section will be temporarily closed during the survey.

Marked detour signs will guide pedestrians around the affected area to ensure safety.

Additionally, a few parking spots near the drilling locations will be temporarily closed to accommodate the necessary work.

The geotechnical survey marks a crucial phase in the ongoing efforts to restore the Deschutes Estuary.

    Sad that some of our elected officials seem to lack institutional knowledge as to why the lake was originally made. I guess after emptying it, the reasons will become clear.

    I wonder if the project name was deliberately funny.

    The entire Port peninsula should be sampled with core drilling to find the hidden poisonous dioxin areas that pollute the subsurface. This is our own Love Canal that is hiding toxic chemicals from the old creosote operations. The toxins were dug up and relocated. as fill. No one should come in contact with contaminated soils as dioxin is transmitted through touching the materials. especially children. Tell the Port of Olympia to sample the whole area.
