Local conditions
Survey conditions in Ada County
Ada County is one of the fastest-growing counties in the United States, and that growth is pushing development onto foothill terrain, irrigated agricultural land, and floodplain-adjacent parcels along the Boise River corridor — ground that requires precise survey control before a single stake is driven or a foundation form is set. Boundary ambiguities inherited from historic agricultural subdivisions, combined with active floodplain mapping and local Ada County Highway District right-of-way requirements, mean that errors caught in the survey phase cost far less than errors discovered during construction or permitting. Our field crews, dispatched through our Salt Lake City regional hub and scheduled on a project-coordinated basis, provide boundary, topographic, and construction staking surveys referenced to current control and delivered in formats your design and construction teams can use directly. Work is coordinated in advance; contact us early in your project schedule to confirm crew availability.
Ada County's mix of Boise River floodplain edges, irrigated bench lands, and foothill terrain means topographic surveys often need to capture drainage patterns and existing irrigation infrastructure that directly affect grading design. Winter conditions in the Treasure Valley can affect field access and ground conditions, so scheduling survey work in fall or early spring helps keep downstream design timelines intact.
FAQ · Ada County
Does Ada County or the City of Boise require a licensed Idaho surveyor of record for subdivision plat work?
Yes. Idaho Code Title 54, Chapter 12 requires that plats and recorded boundary surveys bear the seal and signature of a Professional Land Surveyor licensed in Idaho. Our survey work in Ada County is performed under the responsible charge of an Idaho-licensed PLS, satisfying this statutory requirement for plat recording and related submittals to Ada County Development Services.
How does floodplain mapping along the Boise River affect the survey scope on our site?
Parcels near the Boise River may fall within FEMA-mapped Special Flood Hazard Areas shown on current Flood Insurance Rate Maps. When that applies, your survey scope typically needs to include established FEMA flood zone data tied to NAVD 88 vertical datum so your engineer can prepare or reference an Elevation Certificate. Confirm the applicable FIRM panel with Ada County prior to finalizing the scope.
What coordinate and datum standards should our survey reference for submittals to Ada County agencies?
Ada County Development Services and the Ada County Highway District generally expect horizontal control referenced to NAD 83 (typically Idaho Transverse Mercator or Idaho State Plane West Zone) and vertical control referenced to NAVD 88. Confirm current requirements directly with the receiving agency before the survey begins, as datum and projection preferences can vary by project type and submission pathway.
