Areas We Serve Around Portland

Our engineer network covers Portland and Multnomah County along with Washington and Clackamas counties. Hillside and mapped hazard sites are covered, with referral to geotechnical specialists where the question is the ground rather than the structure.

How Portland Divides Up

Portland is organised by topography more than by anything else, and topography is what decides structural risk here. The east side is flat, gridded and built out in bungalows before the war. The west side climbs immediately into the hills, where slope, fill and groundwater dominate everything. South toward Lake Oswego the ground steepens again around the water. East county flattens back out into post-war suburbs on ordinary lots.

That produces a genuinely unusual split for one metro. On the flat east side the questions are seismic — unbolted foundations, unbraced cripple walls, rot at the sill where a crawl space stays damp for nine months. In the hills they are geotechnical as much as structural: retaining walls carrying saturated soil, foundations stepping down a grade, and sites on the mapped landslide hazard inventory where a structural opinion may not be sufficient on its own. Same city, same era of housing, different discipline.

Areas We Cover

Where the Coverage Ends

We cover the Oregon side of the metro — Multnomah, Washington and Clackamas counties. Vancouver is closer to downtown than much of east county but sits in Washington, which licenses engineers separately, so permit work across the river is a different conversation.

If you would rather work from your own address than from a neighbourhood, the coverage page lists ZIP codes and travel times.
