Spatiotemporal Variability In The Climate Growth Response Of High Elevation Bristlecone Pine In The White Mountains Of California, Andrew Godard Bunn, Matthew W. Salzer, Kevin J. Anchukaitis, Jamis M. Bruening, Malcolm K. Hughes Nov 2018

Spatiotemporal Variability In The Climate Growth Response Of High Elevation Bristlecone Pine In The White Mountains Of California, Andrew Godard Bunn, Matthew W. Salzer, Kevin J. Anchukaitis, Jamis M. Bruening, Malcolm K. Hughes

Tree-ring chronologies from bristlecone pine (Pinus longaeva) are a unique proxy used to understand climate variability over the middle to late Holocene. The annual rings from trees growing toward the species’ lower elevational range are sensitive to precipitation variability. Interpretation of the ring-width signal at the upper forest border has been more difficult. We evaluate differences in climate induced by topography (topoclimate) to better understand the dual signals of temperature and moisture. We unmix signals from trees growing at and near the upper forest border based on the seasonal mean temperature (SMT) experienced by each tree. We find that trees …

Environmental Inequality Dataset, Aran Clauson, Debra J. Salazar, Troy D. Abel

College of the Environment on the Peninsulas Publications

The Disaggreated RSEI model data (also known as RSEI-GM, or Geographic Microdata) version 2.3.4 was downloaded from the Amazon Web Service created by EPA. The RSEI-GM provides detailed air model results from EPA’s Risk-Screening Environmental Indicators (RSEI) model. The results include chemical concentration, toxicity-weighted concentration and score, calculated for each 810 meter square grid cell in a 49-km circle around the emitting facility, for every year from 1988 through 2014. The data can be used to examine trends in air pollution from industrial facilities over time and across geographies. In order to allow for evaluation of toxic-weighted concentration over time, …

Environmental Impact Assessment: Boulevard Park Pedestrian Overpass Removal, Alexandra Frederick, Sean Hecker, Taylor Pearson, Erin Rush, Louisa Talmage Jan 2018

Environmental Impact Assessment: Boulevard Park Pedestrian Overpass Removal, Alexandra Frederick, Sean Hecker, Taylor Pearson, Erin Rush, Louisa Talmage

College of the Environment Graduate and Undergraduate Publications

The proposed action for the Boulevard Park Pedestrian Overpass is to remove the wooden structure and reroute the utilities underground. The utilities would be routed underneath the train tracks at the park entrance, connecting to Woods Coffee and up Bayview Drive. Irrigation and sewer will still be routed into the park but electricity, telecommunications and water will be routed out of the park. The utility conduits will be in separate trenches under the tracks. The park restrooms at the north end of the park will be abandoned to reduce utilities demands (especially water, electricity and sewer). Restrooms are still available …

Skagit County Centennial Trail Extension Environmental Impact Statement, Avery Barbera, Kelley Crider, Vance Frenzel, Sam Kaiser, Jennifer Shore Jan 2018

Skagit County Centennial Trail Extension Environmental Impact Statement, Avery Barbera, Kelley Crider, Vance Frenzel, Sam Kaiser, Jennifer Shore

College of the Environment Graduate and Undergraduate Publications

Skagit County Parks and Recreation Department has acquired 255 acres of land with the help of Skagit Land Trust and private donors for the purpose of extending the Centennial Trail system, which is currently located throughout Snohomish County. The purpose of the acquisition of these land parcels is to 1) install a new water transmission pipeline from Judy Reservoir (a project done by Skagit Public Utility District) and 2) install a 2.5 mile walking trail on top of the pipeline extending from Clear Lake to Big Rock. This document serves as an analysis of the environmental impacts of the trail …

Environmental Impact Assessment: Cordata Community Park Bellingham, Wa, Christian Berres, Andy Basabe, Katherine Weir, Andrew Graminski

College of the Environment Graduate and Undergraduate Publications

The City of Bellingham (COB) is in phase I of the Cordata Community Park project. The community park will the newest park located within city limits. Phase I development will include amenities such as age separated playgrounds, picnic areas including a large picnic shelter, parkour, bike pump track, restrooms, parking and trails. Wetland mitigation efforts will be implemented for this project. Landscape planting, extension of utilities, security lighting, and irrigation will be included.

Environmental Impact Assessment Whatcom Waterway Aeration Stabilization Basin, Candice Trusty, Katie Kissinger, Micah Litowitz, Natasha Motley, Shelby Owens Jan 2018

Environmental Impact Assessment Whatcom Waterway Aeration Stabilization Basin, Candice Trusty, Katie Kissinger, Micah Litowitz, Natasha Motley, Shelby Owens

College of the Environment Graduate and Undergraduate Publications

The Port of Bellingham (POB) has a court order with the Washington State Department of Ecology to address several cleanup sites within the Bellingham Waterfront District. The Aeration Stabilization Basin (ASB) is included in the Whatcom Waterway cleanup site due to contaminated sediments within the basin. The POB has plans to remediate the sediments and transform the entire ASB into a marina, but since that original proposal, demand for more boat slips has decreased. The POB is exploring alternative uses for the ASB site and what the environmental impacts of those uses would be.

Environmental Impact Statement For West Horton Road Extension Phase 1, Sarah Anderson, Lucas Dubois, Madeleine Jones, David Simpson, Corey Stever Jan 2018

Environmental Impact Statement For West Horton Road Extension Phase 1, Sarah Anderson, Lucas Dubois, Madeleine Jones, David Simpson, Corey Stever

College of the Environment Graduate and Undergraduate Publications

West Horton Road currently dead-ends into a roundabout. The proposed action is to build an extension of road to connect the west terminus of West Horton Road to Aldrich Road to its west. The road extension would feature one traffic lane in each direction, one bike lane in each direction, and sidewalks on both sides.
