Q & A
Q: How much longer can the old South Bay Hospital building operate?
A: BCHD has invested a significant amount of time and resources working with seismic consultants regarding the next steps for the 514 N. Prospect Avenue building.
In January 2018, Nabih Youssef Associates made a presentation to BCHD’s Community Working Group regarding the seismic integrity of the 514 N. Prospect Avenue Building (the old South Bay Hospital). Their presentation cited information about a City of Los Angeles ordinance that allowed owners of non-ductile concrete construction buildings 10 years to submit a detailed evaluation of their building(s), and 25 years to “complete all retrofit or demolition work.” This was not a recommendation from Nabih Youssef Associates. Here’s a link to their presentation: https://www.bchdcampus.org/sites/default/files/archive-files/January-2018-Nabih-Youssef-and-Associates-Presentation_CWG.pdf
In November 2020, Nabih Youssef Associates provided follow-up information regarding the status of the hospital building, writing:
“We evaluated the 514 Building in 2017 and recommended seismic strengthening to improve performance. We understand that Beach Cities Health District (BCHD) has determined the recommended seismic strengthening is not economically feasible and intends to demolish the building within 5 years to mitigate the hazard. Given the vulnerability of the building and poor performance of non-ductile concrete buildings in past earthquakes, demolition is prudent.”

In October 2021, ImageCat, working with Nabih Youssef Associates, produced a Seismic Risk Consulting Report for the 514 N. Prospect building. Their report called “The building damage, downtime and probability of collapse with 10% probability of exceedance in the next 3 to 5 years are basically close to what would be expected, and deemed acceptable by most commercial lenders and institutional owners.
“Beyond the next 3-5 years, the risk picture is different. Risk results presented for exposure periods of 10 to 50 years are significantly high, with probabilities of collapse that would likely be deemed unacceptable, especially for buildings that are used for assisted living, memory care, or other medical purposes.” This means that the building can operate within acceptable risk standards relating to insurance and grants until the end of 2026.
