Seaside is one of the most active construction markets on the North Oregon Coast — a combination of resort-driven commercial development, steady residential growth, and the natural turnover of coastal vacation properties creates consistent demand for excavation and land development work. The city’s site conditions are both familiar and demanding: sandy coastal soils with excellent drainage in some areas, heavy clay near Neawanna Creek, and a water table that responds dramatically to seasonal rainfall.
Osburn Olson has completed residential site preparation, commercial excavation, septic system installation, retaining wall construction, and land clearing projects throughout Seaside and the surrounding areas including Gearhart to the north. We know which parts of Seaside drain well and which require engineered drainage solutions. We know the local permit process and what Clatsop County DEQ expects from septic installations in this environment.

Note
North Coast resort community & active construction market
Osburn Olson maintains one of the largest equipment fleets on the North Oregon Coast. We match the right machine to the project — which means your job runs efficiently, on schedule, and within budget. We don’t subcontract equipment; everything we use is ours.
01
Neawanna Creek Drainage Basin
Properties near Neawanna Creek and its tributaries have elevated water tables and seasonal flooding considerations that affect septic design and site preparation.
02
Coastal Sand Soils
The beach-adjacent portions of Seaside have sandy, low-cohesion soils that require specific compaction protocols and foundation engineering considerations.
03
Commercial Density
The Broadway corridor and commercial core require precise equipment access, careful staging, and coordination with active neighboring businesses during construction.
04
Vacation Property Turnover
Seaside's active vacation rental and investment property market creates steady demand for lot clearing, site prep, and septic work on properties changing ownership.
We serve Seaside and the surrounding communities throughout Clatsop County.
