News reports about Trader Joe's sinkhole

Initial Situation

Seiscore Construction was contacted regarding a suspected sinkhole at the Trader Joe's location in Corte Madera. The store was immediately evacuated and closed to ensure public safety, with local news outlets reporting potential sinkhole development beneath the building.

Assessment Findings

Upon professional inspection, our team determined that contrary to initial reports, the issue was not a sinkhole but rather a serious structural deficiency:

  • A critical support column in the meat department had compressed by 6 inches

  • The column showed significant rot damage

  • The wood-framed floor surrounding the column was compromised

Root Cause Analysis

The structural deterioration was traced to the meat department's daily cleaning protocol:

  • Regular end-of-day floor cleaning involved hosing down concrete floors

  • Years of water exposure from this practice had affected the wooden structural elements

  • Cumulative moisture damage led to rot in both the floor framing and support column
