Installing Inground Trampolines in Oregon's Marine / Mediterranean Climate
Oregon presents a unique set of conditions for inground trampoline installation. With 15–90 in of average annual rainfall, marine / mediterranean weather patterns, and soils dominated by Volcanic loam (Willamette Valley) and Marine clay (Coast), every project requires a custom-engineered approach. We do not use one-size-fits-all pit designs.
Oregon is our best Pacific Northwest state. The Willamette Valley's volcanic loam is exceptional — well-draining, stable, and easy to excavate.
Drainage Engineering
- Willamette Valley: excellent volcanic loam — among best in US
- Coast: marine clay requires daylight outlet, may need sump
- Eastern: arid, minimal drainage
- Heavy winter rain: overflow scupper in western Oregon
Installation Timing
- April–October (Western)
- May–September (Eastern mountains)
Base. Coast range steep access +10%. Remote eastern +15%.
