The Intertwine Alliance

Creating A Movement for Parks, Trails and Natural Areas

A few years ago, we realized that all of our greatest achievements had one thing in common. Whether launching a natural area acquisition initiative, completing a new trail, or opening a major new park, behind every major success stood a coalition of public, private and nonprofit organizations and leaders. So, we thought, rather than put this coalition together each time we want to do something big, why not put it together and keep it together and keep doing big things?

The Intertwine Alliance uses a "collective impact" approach, a model that is emerging worldwide as best practice when addressing large-scale social and environmental challenges. 

So that’s what we’ve done.

The Intertwine Alliance is a coalition of private firms, public agencies and nonprofit organizations working together to tap new sources of funding, better leverage existing investments, and more fully engage residents with the outdoors and nature. The Intertwine Alliance uses a collective impact approach to its work. Collective impact is the commitment of a coalition of organizations from different sectors to a common agenda for addressing a complex social or environmental challenge. 

The Alliance was built over many years, but was formally launched as a nonprofit in July 2011 with 28 partners. Today, we have more than 100 formal partners. 

The Alliance exists to ensure the region’s trail network gets completed; that our natural areas get restored, and that people of all ages discover they can enjoy the outdoors near where they live. We exist to make our region more attractive to new businesses and to help our existing companies attract talent. We’re here to reduce utility and transportation costs and keep our water clean. Finally, we’re here to help our partner organizations build their capacity and become more successful.  

You can learn about our activities here and we hope if you haven't done so yet, that you will join The Alliance and help us build a movement for parks, trails and natural areas in the Portland - Vancouver region!

The Alliance has two fundamental objectives: Investment and Engagement. We build leadership, investment and leverage; and we engage civic and elected leaders and residents. Read about initiatives that The Intertwine Alliance currently has underway to support these objectives.

Leadership, Investment, and Leverage

The Intertwine Alliance was formed to foster new local, regional, state, federal and private investment and to help Alliance partners better leverage existing investments. We do this by facilitating regional plans, setting priorities, developing funding strategies and helping build and coalesce civic leadership. Projects and initiatives that support this objective are below.

  1. The Intertwine Executive Council on Active Transportation identifies emerging priorities for the region’s active transportation network. It is currently involved in the development of a region-wide Active Transportation Plan.

  2. A coalition of conservation leaders, convened by The Alliance, recently completed the region’s first Regional Conservation Strategy and Biodiversity Atlas.

  3. The Alliance is undertaking a Regional Urban Forestry Plan. The Oregon Department of Forestry, Washington Department of Natural Resources and Metro are the lead partners.

  4. The Alliance convenes the region’s parks directors quarterly to share best practices and identify emerging issues and opportunities. Metro has been the lead partner, although other partners and The Intertwine Alliance office itself are now stepping in to support this collaboration.

  5. The Intertwine Alliance is working with similar coalitions in Chicago, Houston, Cleveland, Los Angeles, the Bay Area, Kansas City, and Milwaukee to develop a national agenda for conservation in urban regions, establish conservation coalitions as national best practice, and help attract and coordinate federal investment.

  6. Through the Our Common Ground campaign, The Intertwine Alliance helps residents discover that they can be active in the outdoors close to home and as part of their everyday lives. The Alliance also supports elected and civic leaders in being more effective leaders on parks, trails and natural areas issues. A number of projects, programs and initiatives support this goal.

  7. The Alliance manages a website that is a central portal to nature in the region. The website is a clearinghouse for nature-oriented events and for the first time information from the more than two dozen agencies managing parks and trails is available through a searchable map interface.

  8. The Alliance publishes the "Our Common Ground Report," which makes the case for investment in parks, trails and natural areas in the Portland-Vancouver region. 

  9. Alliance partners are implementing an integrated Intertwine parks and trails signing system that allows residents to navigate the region’s network of parks and trails—which is managed by 28 different agencies—as if it was one integrated system.

  10. The Intertwine Alliance creates jobs and strengthens tourism in the region by packaging and promoting adventures in the outdoors. The Alliance produces print materials and maintains this site to provide information to residents and visitors of the region.

  11. The Intertwine Alliance convenes two major summits every year, where Alliance partners and stakeholders gather to share success stories, network, and work together on important regional initiatives.
