Oh, yeah....when Northridge hit, it knocked each and every one in a huge Newhall park off the foundations, taking the gas lines out.
Each. And. Every. One. burned to the ground.
All new codes and CMU blocks are not part of the new code. The park you are talking about was a “o” property line park and it worked like a apartment building. Witnessed a 65 unit apartment burn to the ground because of a grill on a wood deck.
