Foundation settlement repair in San Diego, where construction eras sit side by side

San Diego proper carries more construction-era variation in one place than most of the county. Established neighborhoods built in the early-to-mid twentieth century sit within a few miles of postwar and later tract development, and often the two eras are separated by a single block. That matters for settlement questions because older and newer construction tend to carry different profiles of what typically shows up first — older homes have had more decades of soil moisture cycling and prior repairs to accumulate visible effects, while newer construction on a more recently graded pad is more likely to show early settlement if the original soil compaction was inconsistent. That age mix is the actual local factor here, not a single soil type — a two-block walk in much of the city can cross from one era into another. Any specific claim about what a given property's soil is doing is something only a licensed structural or geotechnical engineer can confirm for that address.
