Local conditions
Survey conditions in Gresham
Gresham sits at the eastern edge of the Portland metro where the Willamette Valley transitions toward the Columbia River Gorge, a geography that combines gently sloping valley soils, volcanic fill material, and terrain that rises quickly toward the foothills. Development pressure across the city—ranging from infill residential and mixed-use redevelopment along the Burnside corridor to industrial expansion near the airport freight loop—means that survey control established early saves money and prevents permit delays. Our firm dispatches licensed survey crews to Gresham project sites through our Seattle regional hub, providing boundary delineation, topographic data collection, and construction staking services coordinated to your project schedule. Survey crews work to legal descriptions, recorded plats, and design drawings to put control on the ground accurately so grading, utility placement, and structural work proceed without costly repositioning. Coverage is scheduled and project-based; contact us to align crew dispatch with your construction timeline.
Western Oregon's wet season, which runs roughly October through April, can compress outdoor survey windows and affect the legibility of existing monuments in saturated, disturbed soils common to active construction zones. Gresham's proximity to Columbia River floodplain areas means some parcels carry floodplain boundary considerations that intersect directly with topographic survey deliverables.
FAQ · Gresham
How does Gresham's proximity to floodplain areas affect my topographic survey requirements?
Portions of the Gresham area fall within or near FEMA-mapped Special Flood Hazard Areas. When a project parcel is near a floodplain boundary, the topographic survey must establish accurate finished-grade elevations tied to NAVD 88 datum so that your engineer or floodplain administrator can determine base flood elevation compliance. We collect and report elevations with sufficient density and datum documentation to support that determination without a separate return visit.
What datum and coordinate system should my Gresham survey reference?
Oregon projects typically reference the Oregon Coordinate Reference System (OCRS) or Oregon State Plane (North or South zone, NAD 83) for horizontal control, and NAVD 88 for vertical. We confirm the datum requirements with your engineer or the City of Gresham permit office before fieldwork so that survey deliverables integrate directly into your design files and permit submittals without datum conversion errors.
Can construction staking proceed during Gresham's rainy season, and what limitations should I plan for?
Staking can proceed in wet conditions, but saturated ground reduces stake holding capacity and can accelerate monument loss from equipment traffic. We use lath, hubs, and guard stakes sized to site conditions and schedule staking in phases that match active work fronts rather than staking the full site at once. Coordinate with our scheduling team at least one to two weeks ahead of each phase to allow crew dispatch from our Seattle hub.
