Recent Projects

Collective Betterment Environmental (CBE) partners with state and federal agencies, tribes, and conservation organizations to deliver science-driven geomorphic analysis, hydraulic modeling, and restoration planning across watersheds in the Pacific Northwest and beyond. Each project reflects a commitment to high-quality data, clear communication, and collaborative problem-solving. CBE has a history of quality work, from basin-scale strategic planning and fish passage analysis to detailed hydraulic modeling and conceptual restoration design.

Wenatchee Valley College - GIS Lidar

Greg recently collected and processed high‑resolution, post‑flood lidar and imagery at the Lower Peshastin Creek Habitat Restoration Project to provide detailed datasets for his GIS students to use in change‑detection analysis. He collected the lidar and imagery using a Matrice 350 RTK UAV equipped with an L2 lidar sensor and a P1 camera. He used Post‑Processing Kinematic (PPK) methods to achieve near survey‑grade positioning. Greg regularly handles the processing and mosaicking of large lidar datasets to support his geomorphology work.

Salmon Cassal Feasibility and Preliminary Design

Greg managed the initial phases of a river restoration project on the Methow River focused on enhancing cold-water refuge habitats for endangered salmonids. He collected high-precision topographic data using RTK GNSS in a coordinated effort with drone-based LiDAR acquisition. Greg combined this new survey with existing bathymetric information to develop 2D flow models, providing insights into thermal refugia and geomorphic processes. He also helped develop the initial concepts for follow-up engineering design.

Upper Mill Creek Geomorphic Assessment and Strategic Action Plan

Greg led the initial phases of a comprehensive geomorphic assessment and strategic action plan to identify and prioritize restoration opportunities across Mill Creek and its tributaries. He hiked and collected data along 14 miles of river, identified potential project reaches and potential restoration actions. The resulting Strategic Action Plan is expected to guide basin restoration investments for years to come, helping state agencies target the most ecologically meaningful actions.

Upper South Fork Skokomish River Restoration Design

Greg served as the lead geomorphologist on a 14-mile reach assessment supporting the development of a watershed restoration conceptual model. He created high-resolution landcover classifications, performed 2D HEC-RAS modeling, analyzed LiDAR point clouds, and integrated multiple datasets to inform restoration opportunities and channel–floodplain function.

Shasta Dam Physical Data Gaps Study for Chinook Salmon Reintroduction

Greg led a basin-scale physical habitat gaps analysis to evaluate potential pathways for reintroducing Chinook Salmon above Shasta Dam. Work included merging high-resolution topographic and bathymetric lidar datasets across multiple sub-basins and developing 2D hydraulic models covering 21 miles of river channel.
