The Clackamas County Circuit Courthouse won the DJC Oregon Top Project of the Year Award! The $313 million, 257,000-square-foot facility opened on the Red Soils Campus in Oregon City, replacing the obsolete 1936 downtown Courthouse. The new courthouse has fourteen courtrooms, twenty judicial chambers, jury assembly, and improved prisoner transfer functions. HHPR provided civil engineering, survey, land use planning, and natural resources for the project. Congratulations to the design team and all involved on this great project!

We would like to welcome our newest hires to HHPR! A great group of professionals to add to the firm.

McKay Road NE Safety Improvements Project | Marion County, OR

HHPR was hired to help alleviate the leading cause of fatal and serious injury crashes along McKay Road in NW Marion County. The McKay Road NE Traffic Safety Improvements project was ARPA funded and focused on 1.1 miles of highway widening to provide a 6 foot wide striped median with rumble strips to provide additional separation between on-coming traffic through three existing curves along the corridor. The project was completed late 2025 and included over a mile of replaced guardrail, nearly 7,000 tons of asphalt, and thousands of feet of highway ditch line regrading and landscaping. HHPR provided civil engineering, survey, environmental services, landscape architecture and and construction administration support for Marion County.
