Minor Earthquake and Current Photos

A minor earthquake did no apparent damage, but was a good reminder of what’s at stake in making the buildings along Esplanade Ave. safe. It also gave a great excuse to tour the beach below the properties, look for new dirt falls, and check out the current works along the bluff.

310 and 320 Esplanade Ave as seen from the Beach

As seen from the base of the bluff below the “dog park” by Lands End on Esplanade Ave, this is 310 Esplanade on the center left, and 320 Esplanade on the right.

South end of 320 Esplanade

This view of the south end of 320 Esplanade shows the undercut cement of the apartment patios. On the right is 330 Esplande. It is missing between 40 and 45 of patios, as well as all of its decks and railings. The shredded material below 330 is the remnants of the sprayed cement “shotcrete” wal and soil nails intended to halt the bluff erosion and protect the property.

South end of 320 Esplanade – Detail

The majority of 320 Esplanade continues to rest on solid bluff, but the right corner of the building’s foundation is unsupported. This smaller part of the building was its laundry room. The dangling sandbags and black plastic is all that’s left of a large tarp placed to stop rain and water erosion.

330 Esplanade Bluff and Dirt

The surface of the bluff below 330 Esplanade was sealed with sprayed shotcrete cement. The project to anchor all of the cement with steel rods after only the top three or four courses of rods. The contractor stated that the wall failed because it was incomplete, and recently it has sued the property owner for lack of payment for the work.

Completed Textured Cement Wall Below 360 Esplanade

This is apparently what a finished shot crete and soil nail wall would like. The cement is colored and textured to make it blend with the neighboring sandy bluff.

330 Esplanade Bluff and Wall

The ends of clusters of long metal rods called soil nails are bolted together in rows at the top of the bluff. The sprayed cement sealed the sandy bluff surface to protect it from rain and spray, but was not meant to be the final, permanent outer surface. The project stopped befiore it was done, apparently because the owner did not pay the bills.
