Confluence Principal Coastal Engineer, Jessica Côté, will be an instructor for a 2-day soft shore protection workshop Wednesday-Thursday, October 23-24, at the Center for Urban Horticulture. Participants will learn about Green Shores for Homes, a voluntary program similar to green building rating programs such as Built Green and LEED, with a focus on waterfront properties. The workshop, offered by Washington SeaGrant, is designed for professionals (biologists, engineers, planners, landscape architects) and contractors, local and regional government staff, and others seeking to implement the Green Shores program for a shoreline improvement, new design or development, or other related shoreline projects.

Confluence has soared to new heights! We have added drone aerial data collection/unmanned aircraft systems (UAS) to our toolbox. Confluence has successfully deployed UAS capabilities on a diverse array of project types, and continues to develop and apply innovative approaches to interpreting data collected with this technology. Confluence integrates UAS activities with our core expertise in GIS and spatial data analysis to provide clients with unique opportunities to evaluate site conditions and impacts for transportation, infrastructure, and natural resources projects. For example, with our drone (DJI Phantom 4), we can document status of infrastructure, water quality, shoreline characteristics, wildlife habitat, and vegetation cover. Our UAS staff includes Phil Bloch, Grant Novak, and Hans Hurn, who each holds FAA airman certificates for UAS operations and has expertise in the rapid deployment of UAS services for clients.
