Foundations built to an engineered plan, not organic growth
Research Triangle Park developed under a formal 1958 master plan by landscape architect Lewis Clarke, with construction following the park's 1959 founding rather than growing organically over a century the way Durham's older towns did. That means foundations near RTP generally date to a narrower, more recent construction window with more consistent engineering standards.
Piedmont clay still applies, even to newer construction
Regardless of when a building near RTP went up, it still sits on the same shrink-swell Cecil clay found across the Durham County Piedmont, and that soil doesn't care how recently a foundation was engineered. Even newer, well-designed foundations near the park benefit from periodic drainage and settlement checks given the clay's seasonal movement.
