Gearhart occupies a special place on the North Oregon Coast — a quiet, residential community tucked between Seaside to the south and the open coast to the north, characterized by its coastal dune topography, mature vegetation, and the low-lying terrain near the Necanicum River estuary. Development here tends toward careful, site-specific residential work: new home builds, lot clearing, septic system installation on soils that require thoughtful engineering, and retaining wall construction on the sloped dune terrain.
Osburn Olson has worked Gearhart residential projects for decades. The combination of sandy dune soils, seasonal high water tables, and the sensitivity of the coastal environment here demands exactly the kind of experience we bring — knowledge of what each part of the Gearhart landscape requires, familiarity with local permit timelines, and the precision to execute on sites where neighbors are close and the visual impact of construction matters.

Note
Quiet coastal residential community — dune terrain specialists
The North Oregon Coast is not a uniform construction environment. Gearhart has specific site conditions, soil profiles, and permit considerations that require local expertise. Here’s what we account for on every project we take here.
01
Coastal Dune Topography
Gearhart's dune-influenced terrain creates variable elevation and soil composition across short distances — requiring site-specific assessment before every project.
02
Necanicum River Floodplain
Lower portions of Gearhart near the Necanicum estuary are subject to seasonal flooding and have elevated water tables that affect septic feasibility and drainage design.
03
Mature Vegetation & Aesthetics
The abundance of wetlands and coastal marsh near Hammond means many parcels require a wetland delineation and potential Department of State Lands (DSL) removal-fill permits before any ground disturbance.
04
Sandy Soil Drainage Variability
Gearhart soils range from excellent-draining beach sand to moisture-retaining vegetated dune profiles — proper assessment is critical before septic design or grading.
We serve Gearhart and the surrounding communities throughout Clatsop County.
