Golden Gate bridge

27 December 2007

Broadway heads up into the hills, and just past the connection to Route 24 it passes over a sturdy WPA-era concrete structure. A pocket valley here holds the College Preparatory School, and Golden Gate Avenue, one of Upper Rockridge’s main arteries, goes under Broadway here to its end at Chabot Road where Temescal Creek enters a culvert. The Golden Gate bridge (formally it’s the Golden Gate Avenue undercrossing) is built to last, but the ground around it is slumping. After the next big quake on the local fault, the bridge may still stand but be unusable, blocking Broadway, because vehicles won’t be able to get up onto it.

The wider setting

22 December 2007

sierra12-21-07.jpg

Yesterday I hiked up into the hills again, this time through the Hiller Highlands neighborhood. It was clear enough to see the Farallon Islands standing crisp against the Pacific Ocean horizon. From a saddle on Grizzly Peak Road, just south of its intersection with Marlborough Terrace, I looked down into the steep, rocky swale where the fire of October 1991 began. It was sobering to sense how strenuous firefighting must be in this setting. Then I looked east, past the shoulder of Frowning Ridge, past a glimpse of wooded Orinda, past the inhabited hilltops of northern Lafayette, the bare ones beyond Clayton Valley and a few whitish hilltops behind them. Wait a minute, I thought, there ARE no hills beyond; that’s the Sierra Nevada. Apparently the area around Lake Tahoe. My little bayside city is a part of something very grand.

Boom disneyfied

The Hiller Highlands neighborhood was wiped clean by the October 1991 Oakland Hills fire. Once a quarry site, it later became a woodsy enclave of cottages. Then all that was wiped out, and an architectural monoculture succeeded it, the precious lots built to the edges with large structures—SUV homes—financed by insurance money. The area will not achieve any charm for many decades, if ever.

This is what the big Hayward fault earthquake will do, only the transformation will be a hundred times larger and extend up and down the East Bay. And it will affect the flats as well. That is why I try, every single day, to take pleasure in Oakland as it is. One day, in the twinkling of an eye, it will be gone, or changed irrevocably.

The high hills

7 December 2007

Last week I climbed from my place in the flats up to Skyline Drive, a gain of about 1400 feet in elevation. My house is a hundred years old; the houses on Skyline are new. My house is conventional and built on firm, level ground; the Skyline houses are contrived and installed in hostile settings.

The views are grand when the weather permits, and it’s a pleasant thing to look up and see lights nestled among the hills at night. But I deplore almost everything else about the houses in the high hills. Sure, much of my attitude is cultural—I was raised in sociable lowland street grids with friendly neighbors, where people walked and bicycled and threw block parties. Skyline is different, a string of isolated fortress dwellings that rubs me wrong. Okay, not my style. Part of my problem is aesthetics. These homes have nothing to say to the world; they exist only to flatter their inhabitants and frame for their owners the views that they ruin for everyone else.

But I oppose them politically too: I deplore the hazards of these houses and the expensive services they demand from the city. Fire protection, water and sewage service, bus lines and waste pickup, all are very costly on these steep, narrow streets. They place city workers at risk. But (of course) there’s geology too. Take a look at what’s right across the road from this house.

It’s a fresh landslide scar, exposing crumbly shattered rock. The light-colored stuff is volcanic ash as friable as sand. That curving line to its right is a fault. As I stood there, grit was tumbling down in steady trickles. And when the next moderate earthquake comes on the Oakland fault, no more than a mile to the west, this cliff will collapse. Houses simply should not be allowed up here.

Knocker, Ocean View Drive

1 December 2007

oceanviewknocker.jpgThe very top end of Ocean View Drive may be the heart of the Upper Rockridge neighborhood. Whereas lower Rockridge has little bedrock to speak of, Upper Rockridge is held up by hard Franciscan chert, metabasalt and mélange. The October 1991 fire wiped out this area, and a few lots are still empty. Before the fire, this fine chert knocker graced someone’s back yard. I enjoy having it exposed to the public, but that access has come at a dreadful price.

To get an idea of why I like this knocker so much, see the three closeups labeled “chert” on my free-wallpapers page.
