Project Components

Building on the project’s goals and objectives, the project team will research how other cities have successfully managed conflicts between trees and sidewalks, develop a toolkit of solutions to apply best practices in Seattle, conduct case studies to test the toolkit on corridors and in spot locations, and engage with the public as the Healthy Trees and Safe Sidewalks Management Plan is developed.

Best Practices Research

The team will use information about existing SDOT practices and conduct new research to learn about approaches to managing conflicts between trees and sidewalks. This work will identify national and international best practices as well as emerging practices and promising areas of new research that could be used in Seattle.

The team will develop a toolkit of resources that can be used to address conflicts between trees and sidewalks or other public infrastructure. The toolkit will include criteria to evaluate solutions in different contexts and provide an array of options to address complex challenges. This toolkit will guide SDOT’s future work and also may be used by Seattle residents.

Case Studies

Case studies will be used to evaluate and recommend successful long-term management strategies for different urban conditions. Three corridors will be selected to test approaches at the block-level or neighborhood level, and three spot locations will be used to consider replicable solutions for individual tree and sidewalk conflicts. The case studies will inform the development of conceptual plans.

Public Outreach

There will be many opportunities for public participation! The project team will create a plan for community engagement, and all activities will be posted to the Project Calendar.
