Rare find off Highway 79: three flat, buildable acres on a quiet cul-de-sac in St. Paul, addressed O'Fallon, in the Fort Zumwalt School District. The ground is wide open and level front to back — no grading headaches, no timber to clear, and an obvious build envelope the moment you walk it. Minimal restrictions mean no mandated builder, no architectural review board, and no clock forcing you to break ground. Bring your own plans, builder, and timeline. Three acres leaves room for an outbuilding, shop, garden, or a deep buffer from the neighbors, on an established street with substantial custom homes nearby. FEMA Zone X (unshaded), minimal flood risk. Minutes to Highway K, Bryan Road retail, I-70, and Hwy 40/61. Buyer to verify utilities, well/septic, soil and perc testing, zoning, and setbacks with St. Charles County; acreage and boundaries approximate. Survey has been attached.
