Winkelman Park Phase One Improvements

Location: Washington County, OR
Client: Tualatin Hills Park & Recreation District

For Phase I of the Paul and Verna Winkelman Park project, the Tualatin Hills Park & Recreation District selected Otak to provide design and construction services for a new multi-use sports field, quality dog park, and parking lot for 50 vehicles on steep, rolling terrain. The park’s improvements required 25,000 cubic yards of earthwork, an elaborate subsurface drainage system, and stormwater management. The dog park was anticipated to draw nearly the same number of users as the sports fields. The heavy usage created challenges for the dog park site design, which included:

• Accommodating dogs of all sizes and personalities;
• Providing a surface that won’t hurt paws, but is durable enough to withstand heavy use in either wet or dry conditions;
• Providing stormwater runoff treatment for dog-use turf areas;
• Protecting newly planted trees from dog activity; and
• Providing a paw-wash fountain and drainage system for large volumes of frequently muddy water.

Otak’s services included site design refinement, erosion control, grading, custom backstop design, civil design, utility upgrades, dog park design, planting, irrigation design, construction administration, and obtaining all land use and construction permits.
