Proposed Condos Unsafe?

Surface Cracking Reveals Evidence of Active Fault

The above image shows a superposition of proposed construction with the USGS published location of the Hayward Fault (trace 187).  Ground photos reveal surface cracking in the existing pavement, potential evidence of active seismicity.

The best fault data available (USGS Geologic Map of the San Francisco Bay region) shows an active fault line (Hayward Fault, trace 187) lying directly beneath a 43-unit condominium complex proposed by financier Richard Blum and the Fairmont Hotel chain.  The presence of the fault is corroborated by ground photos that show surface cracking in the pavement surface.

Developer plans (Oakland PLN16053) call for four stories of residential units above two levels of underground garage.  The underground garage poses particular risk in a seismic event.  Fault separation would threaten failure of supports and catastrophic collapse of the residential tower.

Alquist-Priolo (CA PRC § 2621) is designed to avoid such dangers by requiring that “No structure for human occupancy, identified as a project under Section 2621.6 of the Act, shall be permitted to be placed across the trace of an active fault.”  (14 CCR § 3603)

NACPEX demands a full geologic study pursuant to 14 CCR § 3603(d) and the prohibition of any multiple-unit residential construction project under 14 CCR § 3603(a) if the presence of a fault line is confirmed.

Stop Blum and Fairmont from
putting profits ahead of human safety
