Clay Till Under a Town That Outgrew Its Own History
Westfield sits on the same Crosby-Brookston silt loam and expansive glacial till clay found across Hamilton County, but unlike Noblesville's layered downtown, almost all of Westfield's foundation stock is recent — poured in the last two to three decades as the town's population exploded around Grand Park. That means foundation issues here are less often old construction meeting old clay and more often tied to how a specific subdivision handled that expansive clay during rapid buildout.
Grading and Drainage First
We look first at site grading and drainage history on a Westfield job, since the region's clay-till movement is a given — what varies subdivision to subdivision is how well each development's original grading accounted for it.
