The Greenway was founded on the strength of cooperation and coalition-building, and owes its success in huge part to the many local companies and organizations who sponsor Greenway events year after year.

We welcome opportunities to link identities with conservation-minded organizations in our community, and happily acknowledge their partnerships in our publications and materials. We see these relationships as a classic win-win scenario, raising public awareness for sponsors while generating much-needed funding for the ongoing work of the Greenway Trust.

Read below for available sponsorship opportunities. For more information, or to become a sponsor, contact Mike Woodsum, Director of Development, by e-mail or at 206.382.5565 x26.

Greenway Summer sponsor boothMountains to Sound Greenway 365

Greenway 365 is a year-round celebration of the events and activities happening every day in the Mountains to Sound Greenway. From outdoor recreation to activities like fairs, festivals and special community celebrations, there are plenty of opportunities to explore the Greenway. This new public engagement initiative enables sponsors to have a full year of exposure in connection with the Greenway, reaching a wider audience than ever before. Organizations can support Greenway 365 as an Event Sponsor or a Year-Round Sponsor.





Each winter, Greenway supporters come together for a special dinner to celebrate all that we have accomplished in our ongoing drive to preserve and enhance this special place that we live in.

Sponsorship of the Dinner supports our work in public land acquisition and sustainable growth, enhancing recreation sites and trails, restoring wildlife habitat, rivers and streams, and providing environmental education programs to thousands of children each year... all in an effort to promote a sustainable balance between population growth and a healthy environment.

This annual event is held at the Washington State Convention Center’s skybridge, overlooking downtown Seattle, in early December. Sponsoring organizations or individuals will be listed prominently in the invitation, event program, on large signs at the event, and during the presentation. Example of sponsorship levels and benefits from last event.




The Greenway Breakfast is an opportunity for dedicated supporters of the Greenway to share their passion for our work with others. Many attendees have only recently been introduced to the Greenway Trust. The Breakfast provides a setting to discover who we are, the work that we do, and why it is vital to the future of this region. New connections are formed between a wide variety of guests representing businesses, non-profits, state and local government, recreation groups, and more.

Sponsorship of the Breakfast ensures that all donations received at the event go straight to work out on the Greenway landscape. Sponsors are recognized prominently throughout the event and in accompanying materials. Example of sponsorship levels and benefits from last event.


Tree Planting Tree Planting

Each fall, the Greenway kicks off the tree planting season with a major volunteer event. Restoration work in the Greenway helps to restore native vegetation and improve water quality . Hundreds of volunteers remove invasive plants, plant native shrubs and trees, and restore riparian habitat.

  • Co-sponsorship of $1000 per event will cover some event expenses.
  • Sponsorship of $2500 for the spring event will cover direct expenses for the event, including tools, field materials, transportation, food and drink to support volunteers.
  • Sponsorship of $5000 for the fall event will cover all expenses to run the event, including planning, volunteer recruitment and crew leaders to train and lead volunteers. It will also cover native plants, grown in the Greenway tree nursery, to restore and re-vegetate the site.

Sponsoring organization(s) will be promoted on the Greenway Trust web site, in local news media, in the Greenway Trust newsletter and the email alerts. Banners will be displayed at each event.
