Memo to:

Michael McBreen, Columbia Asphalt & Ready-Mix

From:

Charlie Hammond, C.E.G., and George Machan, P.E.

Date:

January 16, 2018

Subject:

Landslide Monitoring
Columbia AK Anderson Quarry
Parker, Washington

2642

This memo is a status update to prior memos released in December 2017 and January 2018.

Landslide Monitoring
Columbia’s monitoring of the landslide is based on reconnaissance, manual GPS RTK survey data,
Leica total station laser survey data, and drone aerial photography. In addition to these methods,
landslide risks are also tracked with site patrols and 24/7 video cameras providing images of the
quarry pit and Thorp Road.
Manual GPS
As of January 15, new manual GPS data has not been collected. The most recent GPS data was
obtained on January 10, 2018.
A map showing calculated velocity vectors for the rebar hubs and the temporary hubs north of the
quarry is provided as Figure 1. Informational background on the hubs is provided in a December 15,
2017 memo.
Leica Laser Total Station
Total Station laser and data presentation using the Leica web tool “Leica GeoMoS Now!” is in
development, and is available to select team members. Raw data files are manually downloaded
and available. Testing of automatically produced Leica reports is also in development, an example
of a “test” report is provided in Appendix A, as listed below. The grouping for the Leica points is
similar to GPS points, however the point numbers refer to different targets.

Daily Report

Central Group

Prisms 4,5,6,7,8,9, 10, 11, 16, 17,21,and 22

 

This report provides daily plot updates for the Central Group containing prisms 4, 5, 6, 7, 8, 9, 10, 11, 16, 17, 21, and 22.
The plots include:
Relative Change in Horizontal Vector
Horizontal Vector Velocity
Horizontal Vector Graph
Relative Change in Northing
Relative Change in Easting
Relative Change in Elevation
Relative Change in Horizontal Vector Contour Plot
Relative Change in Northing Contour Plot
Relative Change in Easting Contour Plot
Relative Change in Elevation Contour Plot
Data generated by the Leica Nova TM50 Monitoring Station. Relative change is calculated for a 1-week time interval. Actual displacements of individual
prisms over the full monitoring period may be higher. The raw data is presented with Leica's built-in smoothing parameters over a 24 hour interval,
where applicable. No other analysis or interpretation is performed other than combining nearby prisms into groups.
