seattle-sidewalkThe manager of the Seattle Department of Transportation Department will provide an overview of both the City’s Street Tree Management Plan and the Sidewalk Safety Repair Program.  Seattle is responsible for over 40,000 of the City’s roughly estimated 250,000 street trees.  Seattle also manages over 2300 miles of sidewalk assets.  A recent sidewalk assessment showed that approximately 12% of sidewalk related defects may be relatable to trees.  Seattle is also updating its street tree inventory as part of a 9 year strategy funded through 2014.  The discussion will present information on both the strategies and tactics that SDOT is employing to optimize investments in both street trees and sidewalks.

Darren Morgan began his career in Urban Forestry at Paul Smiths College in the mid 90’s.  After a decade of working with trees in the private sector in Pennsylvania, Washington, and Hawaii, Darren joined SDOT’s Urban Forestry program in 2005. Darren was focused on managing Urban Forestry field operations for the unit until 2013, and for the past 5 years has managed SDOT’s Urban Forestry Section. His oversees several programs including field operations, street tree permitting/regulation, and landscape architecture, which includes enforcement of tree protection and land use requirements related to public and private development.  He is an ISA certified arborist and municipal specialist, and has presented on Seattle’s Trees and Sidewalks Operations Plan at ISA conferences in Nevada and California. He is currently working with Seattle’s Urban Forestry Core Team to update the City’s Urban Forestry Management Plan.
