24 HOURS · THE EAST BAY

A hill lot after a fire what changes?

The 1991 Tunnel Fire took 3,280 homes in the Oakland and Berkeley hills. A hill lot answers differently to water and to fire than a flat one. The difference shows up in the rebuild rather than the drying itself.

Why does a slope answer differently?

Water leaves fast and arrives fast. Nothing pools.

On a flat lot water stands and soaks in one place.

On a slope it runs, gathers what it crosses, and hits a wall side-on rather than from below.

So the damage line on a hill house is often high and narrow, not low and wide.

What did the Tunnel Fire leave?

3,280 homes gone across the Oakland and Berkeley hills.

Which means most of what stands up there now is newer than what burned.

Newer construction changes the first morning of a loss, because the sampling window moves.

Not every hill house was rebuilt, and the ones that were not still answer to their own year.

Does that make the hills easier?

On sampling, sometimes. On access, never.

A narrow street, a steep driveway and a house below the road change how equipment arrives.

Fans and dehumidifiers are heavy, and a crew carries them the last part on foot.

Say so on the first call. It changes what turns up and how many people come.

What happens under a hill house?

The downhill side is usually the one holding water.

A cut-and-fill lot puts one wall against soil and the other in the air.

The buried side stays cool, stays damp, and gives it back slowly for months.

That is where the meter goes first, whatever the visible damage says.

Does a burn scar still matter?

A slope that burned stops absorbing and starts shedding.

The roots that held that grade are gone, and so is the litter that slowed a raindrop.

What arrives at the bottom carries whatever the slope handed it.

A hill lot below one is reading somebody else’s ground, not only its own.

What about the rebuild?

A slope adds an engineer more often than a flat lot.

Retaining, drainage and anything carrying weight come off a sealed drawing.

We build to that sheet and do not draw it.

Reconstruction is one written total agreed before board goes up.

Which counter issues the permit?

Oakland or Berkeley, depending which side of the line.

The hills cross a city boundary that nothing on the ground marks.

Two counters, two sets of forms, and a set that satisfied one does not travel.

Confirm the parcel before anybody confirms a schedule.

What does the first half cost?

Emergency fire and smoke work starts at $90 an hour.

It is metered, and the rate card carries all four figures.

Coming up the hill to read the walls costs nothing.

The smoke side is written out separately.

What is not ours up there?

The engineer’s seal and the inspector’s initials.

Both belong to people who do not work here and do not take our word.

Our numbers are CSLB #1131134 and IICRC #70194273.

A hill address asks more, and the guides answer it.

Castro Valley Is Not a City: Permits Change

Castro Valley is unincorporated Alameda County. No city hall, county permits, its own sanitary district. What that changes about closing a wall there.

The Hayward Fault and Closing a Wall, East Bay

The fault runs under seven East Bay cities. It changes nothing about drying and a great deal about what it takes to close a wall again.
