Local conditions
Survey conditions in Hillsboro
Hillsboro sits at the western edge of the Portland metro, where the Tualatin Valley's flat agricultural floor meets the rising terrain of the Coast Range foothills. That transition — from deep, fine-grained valley soils to variable hillside topography — means horizontal and vertical control must be established carefully before a single stake goes in the ground. Washington County is one of Oregon's fastest-growing counties, with active semiconductor campus expansions, industrial tilt-up construction, and residential subdivision development all competing for the same parcels. Misplaced improvements or inaccurate grades discovered after earthwork begins are expensive to correct. Our survey crews dispatched through the Seattle regional hub perform boundary surveys, topographic surveys, and construction staking that translate engineered designs into verified field positions. Every survey deliverable supports downstream work — grading plans, foundation layouts, utility corridors — so that contractors, engineers, and developers can proceed with confidence from the first day of mobilization.
The Tualatin Valley floor west of Portland is underlain by fine-grained lacustrine and alluvial soils that can compress unevenly, making accurate topographic data particularly important for drainage design and subgrade planning. Oregon's wet season extends well into spring, so topographic and staking work scheduled before the summer dry window should account for field conditions that may affect access and instrument setup.
FAQ · Hillsboro
What control network or benchmark datum do your crews use for surveys in Hillsboro?
Crews establish horizontal control referenced to NAD 83 (Oregon State Plane North or South zone, as appropriate for the project location) and vertical control referenced to NAVD 88 using published NGS benchmarks or Washington County survey control monuments. The datum and control sources used are documented in the survey report so your engineer and civil designer can work from a consistent, traceable reference.
Does Washington County or the City of Hillsboro have specific survey or plat requirements we need to meet?
Oregon Revised Statutes Chapter 209 governs land surveying practice statewide, including monument requirements and record-of-survey filing thresholds. Washington County Survey Division administers local plat and partition review. We coordinate the deliverable format and filing requirements with the applicable county or city standards for your project type so the survey package is acceptable at submittal without back-and-forth revisions.
How does Oregon's wet season affect construction staking scheduling in Hillsboro?
Hillsboro averages significant rainfall from October through May. Saturated or muddy site conditions can restrict instrument setup, obscure layout hubs and tacks, and degrade stake durability. We recommend scheduling staking in phases timed to grading progress rather than setting all stakes at once, and flagging critical control hubs for protection. Advance scheduling through our Seattle hub is required; we do not offer same-day dispatch for this location.
