Hammond, Oregon.

Hammond sits at the edge of the Columbia River estuary — one of the most environmentally sensitive and hydrologically complex construction environments on the entire North Oregon Coast. We’ve worked here for decades.

Excavation & Land Development in Hammond, Oregon

Hammond is a small, tightly-knit waterfront community tucked between the Columbia River estuary and Fort Stevens State Park — one of the most distinctive locations on the entire North Oregon Coast. The combination of estuary proximity, high water tables, and the area’s coastal dune and marsh landscape creates a construction environment that demands specific expertise. Lots here are often smaller, access can be constrained, and the proximity to wetlands and coastal waters adds a regulatory dimension that inland contractors frequently aren’t prepared for.

Osburn Olson has been working in Hammond throughout our history — it’s essentially our backyard, sitting just west of our Warrenton base of operations. We know which Hammond parcels have challenging water table conditions, which streets have tight equipment access, and what the DEQ septic process looks like for the coastal soils that characterize this area. When neighbors in this community need excavation or land development work, they call us because we know the terrain as well as any contractor on the coast.

What Makes Hammond Different to Build In

Hammond has specific site conditions, soil profiles, and regulatory considerations that require local expertise. Here’s what we account for on every project we take here.

01

Columbia River Estuary Influence

Hammond's position adjacent to the Columbia River estuary means tidal influence affects groundwater levels, and proximity to water features creates additional regulatory setback requirements for development.

02

Exceptionally High Water Tables

Hammond is one of the areas on the North Oregon Coast with the shallowest average water tables — often 18 inches or less in lower areas — making conventional septic systems frequently infeasible and requiring engineered ATT solutions.

03

Wetland Proximity & DSL Permits

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

Tight Residential Access

Hammond's compact residential layout means many lots have limited equipment staging area and require precise, low-impact operation to protect neighboring properties and established vegetation.
