Urban Forestry Program


Snohomish’s urban forest is an important resource to the City and its residents.  Trees provide a multitude of physical, environmental, aesthetic, and economic benefits.  The Urban Forestry Program is a comprehensive guide to all things plants and planting in the city.  The plan will inventory existing tree coverage and identify areas where increased coverage is needed.  

The Urban Forestry Program includes several distinct plans and projects, described in more detail below.  The first step was a tree inventory, which was completed in the spring of 2023 through a grant from the Department of Natural Resources Urban and Community Forestry Program.  An interactive map can be viewed by clicking the link below.

The Urban Forestry Plan was then adopted by the City Council in 2023.  An update to the City's tree code will then be completed in 2024 and 2025.  This update is expected to establish a tree mitigation fund and an additional plan for how the funds will be utilized.  Plant species for all work within the right-of-way will be included to ensure the right plants are being located in the right area to maximize the benefits of the plants and for low maintenance, environmental sustainability, and visual appeal.  It will work in conjunction with the Complete Streets Project to require attractive streetscapes that are easy to maintain.  

Why Urban Forestry?

Trees are a valuable community asset, enhancing our parks and open spaces, cooling our neighborhoods, capturing air pollution, intercepting stormwater runoff and improving safety in our community. Growing and caring for our city’s urban tree canopy is no small task; a healthy tree canopy is the result of proper planning, management and community involvement.

The urban forest plays a key role in mitigating urban heat islands, reducing electricity bills, improving air quality, reducing flood impacts, improving overall emotional and psychological health and improving physical health.

Taken together, these benefits help save an estimated $44 million annually in reduced healthcare, emergency response and energy costs.

Tree Inventory

The City was awarded the Community Forestry grant from the Department of Natural Resources in order to conduct an inventory of all trees in the public right-of-way as well as in select parks and City properties.  Trees located on private property will not be included.  Basic information about each tree have been collected and mapped.  This includes species, diameter, height, and a basic health assessment.

The information in the tree inventory established baseline conditions of the City’s urban forest.  The baseline was then used to develop the Planting Prioritization Plan, a vital element of the Urban Forestry Program.  This plan identifies areas with unequal access to trees, so that future planting efforts can be focused in those areas.
