Civil engineering for
land development.
Bailey Engineering pairs proprietary planning data, AI tooling, and decades of land development experience to take projects from raw parcel to recorded plat.
Bailey serves 25 cities across six counties.
Headquartered in Eagle, Bailey Engineering engineers land development across Southern Idaho — from Boise to Sun Valley, Nampa to Mountain Home. Every jurisdiction has its own zoning quirks, agency review timelines, and infrastructure constraints. We know them.
Twenty years of land development. 19,913+ platted lots. Southern Idaho.
Bailey Engineering was founded in 2006 and has delivered 19,913+ platted lots, 605 developments, and 317 subdivisions as engineer of record across Southern Idaho's six-county Treasure Valley corridor.
Five disciplines, one continuous workflow.
From the first feasibility question to the day the plat gets recorded, we keep the work — and the data — in-house.
Civil Engineering
Roads, water, sewer, stormwater, irrigation, value engineering — the structural bones of every land development project.
Explore 02Land Planning
Entitlements, layouts, agency coordination, public hearings — the political and procedural side of getting a project approved.

ExploreThe research behind every recommendation.
Before we draw a line, we read the room. Every Bailey recommendation is grounded in current Treasure Valley planning data — application history, commissioner records, staff guidance — so the engineering work starts on solid ground.

Bailey is a place where engineers are paid to think, AI is a force multiplier instead of a buzzword, and the systems get better every week.
