TACOMA SUCCESS STORY

Tacoma’s journey toward becoming a model large community, growing trees for resilience, began with a clear need to work with stakeholders and develop a collaborative urban forestry plan for the whole city. State funding for planning and projects along with regional initiatives and supportive champions enabled the city program to grow and establish more community partnerships and opportunities for co-design and stewardship. 

Throughout the decades, Tacoma’s program has benefited from multiple funding opportunities and the support of community partners and champions. Whether cities are large or small, they can learn from Tacoma’s journey and continued evolution to develop a sustainable urban forestry program using the multiple components of the FERTILE SOIL outlined in this Trees for Resilience Toolkit.

Below is a timeline outlining the development of Tacoma’s urban forestry program and its evolution since the original 1992 Urban Forest Management Plan.

1992 – PLANNING
Management Plan: Urban Forest Management in Tacoma
Tacoma developed its first urban forestry-focused management plan in partnership with the City of Tacoma, Tacoma Public Utilities, Metro Parks Tacoma, and the Port of Tacoma. This plan created the platform and vision for managing the city’s urban forest resources to benefit the whole community.

2019 - FUNDING
Expanded funding support for planning and tree care
The 2019/20 biennium budget included $45K (ongoing) city-owned tree maintenance; $160K (ongoing) hazardous tree financial assistance program; $62,500 (ongoing) tree planting in historically underserved neighborhoods; $30K (one-time) tree inventory, assessments, and work plan.

2019 - POLICY & PLANNING | CO-DESIGN | STEWARDSHIP
Tacoma’s Urban Forest Management Plan
A successful collaborative process ensued involving 10 city departments and 25 work groups through interviews and group meetings to understand their processes and how to improve them. These efforts turned into shared strategies and actions in the Urban Forest Management Plan.

Tacoma Community Tree Map
In Phase 1 of the project, urban forestry utilized the city’s Equity Index with tree canopy data to combine and correlate the relevant mapping throughout Tacoma, in efforts to illustrate the relationship between the environment, equity, and community health outcomes. Phase 2 involves further analysis to create a priority map, determining areas for greatest impact through stewardship strategies, and greening efforts.

The Future – WHAT’S NEXT for City of Tacoma?
After over three decades of developing the tools, collaboration, and key partnerships within and beyond the community, Tacoma’s urban forestry program is poised for further growth and reaching set goals for a healthy and thriving community with trees.

Tacoma developed its first urban forestry focused management plan in partnership with the City of Tacoma, Tacoma Public Utilities, Metro Parks Tacoma, and the Port of Tacoma. This plan created the platform and vision for managing the city’s urban forest resources to benefit the whole community. The goal of the plan was to establish a comprehensive tree management program, focusing on internal operations and improved coordination to manage the city’s urban forest across jurisdictions. Key goals recommended from the plan included creating a tree commission, hiring an urban forester, and adopting a combined annual budget of $650K.

The American Forests Regional Ecosystems Analysis, a collaborative initiative among several cities in the Puget Sound region, was a catalyst for significant policy support and growth of Tacoma’s Urban Forestry Program–centered around planning for, planting, and caring of trees to maximize their stormwater benefits. Over a decade later, the analysis informed the adoption of the 2010 Urban Forest Policy Element of Tacoma’s Comprehensive Plan, which included a 30% tree canopy goal and placement of the urban forestry program within the city’s stormwater department.

A partnership between the city’s Urban Forestry Program and the University of Washington’s Remote Sensing & Geospatial Analysis Lab with a grant from WADNR Urban and Community Forestry to conduct a geospatial canopy cover analysis using current LiDAR data. This project utilized an innovative technique to quantify tree canopy cover using high-resolution aerial imagery, calculate forest change metrics, and select sampling sites for ground-based tree inventories. The impact of this analysis included the determination that Tacoma was only at 19% tree canopy cover, far short of the 30% tree canopy goal the city has set for itself.

The city’s Urban Forestry Program moves to the Office of Environmental Policy and Sustainability (OEPS), signifying trees and tree canopy as assets beyond stormwater.  Opportunities for collaboration and co-design on policy and projects expand as the collective of urban forestry with air and water quality, solid waste, and green building, work to develop, promote, and implement sustainable practices in Tacoma. This integrated work is demonstrated in the 2030 Tacoma Climate Action Plan.

The city embarked on several mapping and analysis projects to accurately quantify its urban tree canopy and analyze the ecosystem services it provides and potential to address equity, human health, and climate resilience. 

Urban Tree Canopy Assessment 

As a pilot community in a regional trees and stormwater modeling study, the city received a robust tree canopy assessment using LiDAR and community-wide analysis to support a holistic urban forestry program in its goals, planning, projects, and stewardship.

Canopy Continuum Project – Urban Heat Map

Along with four other Western U.S. cities in partnership with Portland State University,  Tacoma participates in a project to understand how the urban tree canopy helps to create a safe, clean, and healthy urban living environment, particularly for maternal and child health. 

City of Tacoma Equity Index

City-wide mapping/analysis uses 29 data points sorted into five determinant categories to determine where community members are not able to access services or where services do not meet community needs, which informed the Community Tree Map.

The Greening Research in Tacoma project (or G.R.I.T.) is an effort to understand more about how human health and increased greening intersect in South Tacoma, particularly the Tacoma Mall Neighborhood. This active neighborhood also has more pavement and less tree canopy coverage than the city-wide averages, making it several degrees hotter. These characteristics also contribute to air pollution and polluted stormwater runoff that harm salmon, Southern Resident killer whales, and other wildlife. This unique collaboration of the Tacoma Tree Foundation, The Nature Conservancy in Washington, the University of Washington, and the City of Tacoma is funded by an award from the Puget Sound Partnership and a grant from the U.S. Forest Service.

After over three decades of developing the tools, collaboration, and key partnerships within and beyond the community, Tacoma’s urban forestry program is poised for further growth and reaching set goals for a healthy and thriving community with trees.  Opportunities will increase as Washington State and the U.S. Government focus intense funding to support climate action and environmental justice programs. 

Key commitments on the horizon include:

  • Evolution of the Community Tree Map to incorporate stewardship tools to target areas of greatest need.
  • Enhance the Tacoma City Equity Index and tools to inform and focus environmental justice strategies.
  • Growth of stewardship partnerships with Tacoma Tree Foundation and others to manage Tacoma’s Urban Forest and Natural Areas.
  • Regular updating municipal regulations to support better tree management BMPs, development standards, and tree preservation in the community.
  • The city financially supporting a local tree-centric non-profit in continuing boots-on-the-ground work with the community it serves.
