Clearfield's General Plan, adopted in July 2025, describes a mix of post World War II neighborhoods and later development, and ties much of the city's mid century growth to Hill Air Force Base and the naval supply depot.
On homes from that era, the masonry that stays wettest wears first: chimney tops, steps and the brick courses closest to the ground (NPS Preservation Brief 47).
Grading and permits
Clearfield's code requires permits for excavation, grading, fill or construction, and lets the building official require review of potential mudslide hazards where relevant (Clearfield Code §10-1-3). That provision does not mean the city has a mudslide problem; it gives the city a way to review sites that might.
Not necessarily. The Utah Division of Emergency Management explains why unreinforced masonry has to be identified by evaluation, not by age or appearance.
