The existing conditions and operations of Tacoma's urban forest were audited to provide a research summary that informs the framework of the Urban Forest Management Plan. This Phase 1 Research Summary is a comprehensive analysis and summary of 5 planning elements; 1) Existing Policies and Plans, 2) City Staff Interviews, 3) Benchmarking Research, 4) High-Level and In-Depth Data Analysis, and, 5) Community Interests and Input. Outcomes of this research were applied to the U.S. Forest Service's Urban Forest Sustainability and Management Audit to establish a baseline of Tacoma's urban forest in terms of sustainability, management, and equity. The categories of this audit system and the outcomes that identified Tacoma's strengths and opportunities are applied to the Phase 2 Urban Forest Action Plan completed in November 2019 and anticipated to be adopted by City Council in December 2019.
