Fanno Creek Trail

Dirksen Nature Park Construction

The City of Tigard's Park and Recreation Advisory Board (PRAB) recommended the adoption of the conceptual master plan for Dirksen Nature Park (formerly the Summer Creek property) in 2012. Development of the park has been phased over time. Future plans for park development include street and ball field improvements, additional trails, and more.

Project Updates

  • Fanno Creek Trail Closure  - (updated 7/18/18)
    Fanno Creek Trail will be closed through Dirksen Nature Park starting August 6, 2018. Portions of the trail from Tigard Street to Tiedeman Avenue are expected to remain closed for fifteen weeks. View a trail closure map and detour route.
  • Dirksen Nature Park protects sensitive habitat, connects students with nature – (posted 3/5/18)
    On a recent winter morning, Carla Staedter paused as she led a small group through the woods. All was quiet, except for the trill of a nearby song sparrow. But she has been surprised before at this spot. Read More…

Current Projects

  • Interpretive Shelter, Restroom and Nature Play Project
    Starting in July, construction will begin on new and exciting features in Dirksen Nature Park. The 1,600 square foot shelter with restrooms will be sited between two nature play areas, serving as the central hub for the nature park. It will connect to the Fanno Greenway trail which supports nearly a half million users per year. The project constructs a stone and timber framed shelter with undercover picnicking and two unisex and family restrooms. The nature play areas will include timber structures and climbing elements for children of various ages to enjoy. 
  • Oak Savanna Restoration Project
    Less than 2 percent of historic oak savanna habitat remains in the Willamette Valley. Restoring this remnant oak savanna will provide an opportunity for park visitors to view this important historic landscape. Thinning allows mature oaks to expand their crowns and produce more acorns, which provide food for wildlife. More tree cavities are formed in oaks with larger crowns. The cavities serve as homes for squirrels, birds and insects.

    This project will restore habitat for wildlife species like the western gray squirrel, white-breasted nuthatch and the acorn woodpecker. All use the grasslands and oaks of the savanna for food, cover and nesting. Thinning the savanna increases light to the forest floor, increasing growth of native flowering plants and benefitting pollinators like native bees and butterflies. The site will be carefully monitored by a specialized re-forestation contractor through 2019.

Completed Projects

Oak Savanna Overlook (2017)
Construction is complete on a new oak savanna overlook and wetland boardwalk at Dirksen Nature Park. The oak savanna overlook provides seating to view wildlife and to enjoy the establishing prairie restoration. Hidden around the overlook are bronze depictions of different animals that live in Oregon’s oak savannas.

Wetland Boardwalk (2017)
A wetland boardwalk reaches into a stunning forested wetland hidden in the center of the nature park. Although the site is dry during summer months, winter brings a wet bayou-like setting where tall trees reflect in the water below. The boardwalk allows park visitors to get a close-up look at the trees and to enjoy this unusual setting, all without getting wet!

Dirksen Nature Park Education Center (2016)
Located on the edge of the Dirksen Nature Park, the Dirksen Education Center offers a meeting room and a classroom suitable for groups up to 25 people. It serves as the center for summer nature camps and guided school field trips sponsored by Tualatin River Keepers.

Additional Improvements

  • Exercise Equipment
  • Soft Surface Trails


The City purchased the property through multiple transactions beginning in December 2010 with over $2.5 million in grant support for the project from multiple sources. The property contains a mix of mature forests, wetlands, open space, and existing active recreation facilities. The majority of the property will remain a natural area (approximately 35 acres, about 70 percent, are protected under a conservation easement).
