Mike Marshall, CEG, to Present at the AEG Annual Meeting

Mike will be giving a presentation on the geologic characterization and landslide hazard assessment of the Oregon Coast Range transmission line. If you are attending the meeting, this presentation will be a part of Technical Session #7 this Thursday at 8:40am. Below is a synopsis of the presentation:

 

Geologic Route Characterization and Landslide Hazard Assessment of
Oregon Coast Range Power Transmission Line

bpa-photo-lidar-msmThe Bonneville Power Administration (BPA) elected to replace an aging 115-kV power transmission line in the Oregon Coast Range, which is a belt of uplifted sedimentary and volcanic rocks near the Pacific Ocean. A geologic route characterization and landslide hazard assessment was conducted to characterize and map landslides and identify areas of potential slope instability that could damage transmission structures. The type and occurrence of landslides was evaluated using information gathered through review of geologic maps and literature, aerial photography, Statewide Landslide Database for Oregon (SLIDO), and lidar data. Landslides identified from literature and remotely sensed data were cataloged in GIS and a surface reconnaissance was conducted by GRI. A total of 76 structures were located in areas identified as landslide topography. Ground cracks indicative of slope movement were observed at nine structures and four locations were identified with loose guy wires during the surface reconnaissance. Each of the 331 structures assessed were assigned a hazard rating based on documented or observed landslide features, indications of recent mass movement, and/or observed ground cracks. Structures were rated from high to low risk for the prioritization of mitigation efforts. Of the 331 structures assessed, 12 structures were identified as having a high risk for future slope instability. All but three of the high-risk structures appeared to be associated with sidecast fill placed as part of access road and structure work pad construction. In general, the slope instability associated with the roads and bench areas appeared to be the result of oversteepened, loose sidecast fill placed on steep natural slopes or steep cut slopes.

George Freitag, CEG, to Present at the 2016 AEG Annual Meeting

George will be giving a presentation on the engineering geology of the Meyers Cone along Interstate 84. If you are attending the meeting, this presentation will be a part of Technical Session #17 this Friday at 9:40 am. Below is a synopsis of the presentation:

 

Engineering Geology of the Meyers Cone,
Interstate 84, Columbia River Gorge, Oregon

Lidar and new geologic data have revealed a previously unmapped Quaternary volcanic vent system near MP 49 along Interstate-84 (I-84) in Hood River County, Oregon.  We refer to the feature as the Meyers Cone, which is a 650-ft-high olivine basalt edifice with two prominent flow lobes, the Anderson Point and Trotter Point lobes that extend under I-84 into the Bonneville Pool.  Features including a 25-ft-high, 1,200-ft-long volcanic flow are preserved on the inside of the cone.  A northeast-southwest trending rampart system is present on the west side of the cone and goes toward other newly identified vents to the southwest.  Eruptions on the east side of the cone deposited on a pre-existing, north-sloping, alluvial fan complex. A band of east-west oriented tension features (scarps) on the upper portion of the fan are interpreted to be the result of destabilization of the fan by deposition of material near the fan toe.  The historic Fountain Landslide along I-84, east of the Meyers Cone, is located near the toe of the fan.  Previous workers interpreted the subject area solely as a distal portion of the Trout Creek Hill basalt (385 Ka) that flowed down the Wind River drainage from Washington and temporarily blocked the Columbia River. Beginning with railroad construction in the 1880s, the Historic Columbia River Highway in 1914-15, US-30 in the 1950s, and I-80N/I-84 in the 1960s, the geology of these transportation routes has been influenced by the Meyers Cone.  We propose that the cone should be officially named after Joseph Meyers, the Oregon geologist who first identified some of the flow features in the 1950s.

8th Annual Kickball Without Borders Fundraiser

img_20160820_103456A few GRI kickball enthusiasts took part in the 8th annual Engineers Without Borders (EWB) fundraiser.  It was a blistering hot day, and each team brought their top competitors.  GRI took the field first and was able to hold back the opponent the first few innings, but after several scoring runs we lost the first game.  After a small break, GRI was back on the field facing off against a new team.  Every inning we seemed to be evenly matched, and after a few controversial plays the other team eventually pulled ahead.  Now 0-2 we had one more game to restore our honor.  There was no way we could walk away without a win and it was time to take the field for the last time.  Third time is a charm, because we dominated our third game.  Unfortunately, we did not qualify to make it to the next round…but there is always next year.

GRI is a big advocate of the EWB organization and was one of the sponsors for the event.  The GRI team captain, Kyle Wolfe, also regularly volunteers for the organization.  Currently he is the Responsible Engineer-in-Charge for the Honduras Program.  Thanks to the contributions of all the sponsors EWB was able to raise $20,500, which will be distributed between the active EWB projects.

Groundbreaking at the Vancouver Waterfront Park !

test-2The ground breaking ceremony of the Vancouver Waterfront Park – Grant Street Pier took place on July 18, 2016, and commenced Phase I of park construction for this project, which has been in the making for more than 10 years. The renovations will reconnect downtown Vancouver to the Columbia River and inspire a new vivacity in the Vancouver Community.

GRI’s Washington office, located in downtown Vancouver, has taken an active role in the development stages of the project and is excited to provide geotechnical support to an innovative transformation of the Vancouver Waterfront.  GRI conducted the geotechnical investigation for the Grant Street Pier and core park improvements, which include a large plaza, viewing platforms, and riverfront access.  This investigation included review of available geotechnical information for the site; subsurface explorations; laboratory testing; and engineering analysis for the planned pier, walls, and other improvements.  GRI is currently providing construction engineering services to support construction of the Grant Street Pier foundations.

The planned location of the 7.3-acre Vancouver Waterfront Park is on the north bank of the Columbia River in downtown Vancouver at the site of a previous Boise-Cascade paper finishing plant.  The park will be approximately 2,300 ft long, will extend about 250 ft north of the river, and is scheduled to open to the public in 2017.

GRI CELEBRATES EARTH DAY AT TRYON CREEK STATE PARK

This past weekend GRI employees and family members participated in the SOLVE IT for Earth Day Event at Tryon Creek State Park.  GRI worked with several other community volunteers and pulled out non-native English Ivy from surrounding native vegetation. Together with 7,000 volunteers across the state of Oregon we cleared 12 acres of non-native invasive plants from 170 parks, waterways, neighborhoods, and natural areas!

English ivy has become a major issue for Pacific Northwest Forests and Parks.  This past Saturday GRI got a first-hand look at the invasive plant species.  Thick mats of vines covered the ground surface and climbed any adjacent object including old stumps and trees.  This becomes a problem for the native vegetation because the mat of ivy prevents significant amounts of light from reaching the forest floor and the climbing ivy roots can potentially damage mature trees.

GRI is proud to take an active role in the local environment by restoring the native plant community to its previous state before the introduction of non-native invasive plants.  For more information on how to volunteer for the next clean-up day, visit: http://www.solveoregon.org/
