Our Tree Code Protects Profits, Not Trees
In 2023, Seattle passed a tree ordinance which was the culmination of months of meetings between the developer lobby and city officials. The ordinance granted the developer lobby nearly everything on their wish list and resulted in two completely different tree ordinances, one for homeowners and one for developers. In the 6 months leading up to the passage of our current tree ordinance:

108

There were 108 meetings between the city and the developer lobby discussing tree code management.

3

There were only 3 meetings between the city and the the city-created Urban Forestry Commission.

28

28 of the developer lobby's tree ordinance requests went their way. See their wish list here.

This Code Snip Speaks for Itself

The new tree ordinance lets construction companies remove trees of any size for any reason. See for yourself:

Housing Versus Trees is a  False Dichotomy

Housing Versus Trees Was Legally Debunked

In 2021, Seattle's hearing examiner rejected the developer lobby’s claim that trees hinder housing development. After reviewing extensive evidence, the examiner determined that large trees on lots could be preserved without impacting maximum housing capacity, proving the developers' argument was false. Learn more in the FAQs.

Architects and Urban Planners Also Reject It

We work with AIA architects and urban planners who help us prove housing can be built with trees. So far, architects have shown that almost every single tree removal we've seen so far on private property could have been prevented with smarter planning, with the same amount of housing built.

Seattle's Trees Are Hens Guarded by Foxes in The City Building Department

The Building Department Emboldens Illegal Removals

The city building department is in charge of enforcing the tree code. Instead of enforcing the few protections we have, they:
  • Routinely approve illegal removals
  • Routinely approve illegal removals
  • Alter and contradict their permit records
  • Close public complaints without any investigation
  • Allow after-hours illegal tree removals

Corruption Is In The Air

Some developers even brag about the revolving door between the city’s building department (SDCI) and their employees:

The Reports Say It All — See For Yourself

The city building department was recently audited by the city. The audit revealed nepotism, collusion, and legal forms of corruption. Tree Action Seattle’s own report revealed how SDCI routinely fails to enforce basic tree code.

Urban heat  islands

Why Trees Matter

Urban heat islands are caused by the temperature difference between built, urban areas and the surrounding natural area. This temperature difference is caused by the removal of trees in cities. Seattle is 5th in the nation for worst urban heat islands.

Seattle With Wildfire Smoke
Summer 2020

#5

Seattle is top 5 in the nation for urban heat islands ¹

400

Over 400 people died of heat-related illness during our last big heat wave ²

20° F

Trees in Seattle can cool city temps by up to 20 degrees Fahrenheit ³

5%

Energy consumption increases up to 5% for every 2° F temperature increase in cities ⁴

The Impact of Urban Heat Islands

Worse summer Heat

While Seattle is not as hot as cities like Phoenix, summer temperatures now routinely climb into the unhealthy and even fatal range. 400 people died in Seattle’s 2021 heat wave. ²

Public Health problems

UHIs and extreme heat add pollutants to urban air and stormwater runoff, are linked with chronic illness, increase heat-related deaths, worsen our mental health, and more. ⁵

Increased energy consumption

For every 2° F increase in temperature, cities use 0.5 - 5% more energy. The more energy we use, the hotter our city gets, perpetuating the creation of urban heat islands. ⁴

This is an Equity Issue 

Seattle’s worst urban heat islands are located in its lowest-income communities that already have the worst tree protections. We are stacking the deck against our most vulnerable communities.
