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.

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…
- 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.
