Living on a canyon edge street

The slip came in folded into eighths, the way paper comes back from a pocket, with a ZIMAS printout clipped to it. One parcel at the end of a cul-de-sac, marked in yellow pencil, and a note in the margin in blue ballpoint: what does the drop actually change?

The question we filed

The reader is weighing a small house at the tail end of a hillside lane, where the back fence stands against open slope and the chaparral keeps going down until the canyon floor takes over. They asked three plain things. What does the lot include. Where exactly does it stop. And what does a fence mean in the months when the wind comes up the canyon. We filed the slip with the other hillside questions and went to the public paper first, because that is where the answer begins.

What does the parcel report say?

Start with the ZIMAS parcel report, the city's own map and inventory, free to anyone with an address or an assessor's number. For a lot like this the fields to read first are the lot area, the zone, the hillside flag, and the fire hazard severity line. The county assessor's roll gives the recorded dimensions of the same parcel, and reading the two together settles one thing quickly: on a canyon edge lot, the deeded area and the buildable area are rarely the same story. The parcel may run to the top of the slope, or stop at a mid-slope line drawn when the tract was subdivided, and either way the hill behind the fence is mostly not floor area. It is view, it is obligation, it is October.

Who owns the slope?

The fence is not the line. That is the second thing the public paper settles. When an escrow opens, and the escrow number goes on the tab of a folder, the preliminary title report follows within days, and on canyon edge lots it often lists easements along the rear: a slope easement dedicated on the tract map, a drainage easement in the swale, sometimes a public easement for slope and brush purposes. The recorded tract map, held by the county recorder, gives the bearings and distances. The fence, by contrast, was set by whoever had a post hole digger and a free weekend. On these streets the two usually disagree, quietly, by a foot or so, and nobody minds until somebody sells.

What the house itself answers

The third answer is standing on the lot. Houses built out to a canyon edge tend to show their era in the details: clinker brick in the chimney, a sleeping porch since enclosed into a bedroom with the best window in the house, knee braces under the eaves where the roofline hangs out over the drop. The rear yard usually sits on a terrace held by a concrete retaining wall, poured by a crew that may or may not have pulled a permit. If the paper exists, the city has it, and the LA City Planning sheet for the parcel also says whether an HPOZ overlay applies. Inside the Highland Park-Garvanza HPOZ, changes to the exterior go through review before they go through a contractor.

What does October ask of the fence line?

The ZIMAS report carries the fire hazard severity zone line, and in these hills it is the strict designation. The LAFD enforces brush clearance on parcels that carry it, and the clearance distances reach past a back fence on many lots, onto ground the owner may hold only as slope. So the practical question becomes who clears what, and the answer sometimes lives in the easement language described above. Red flag days change the routine as well: the warning goes up, parking narrows on the lane, and the application an insurer sends asks plain questions, distance to brush, distance to slope, that a flat block never has to answer.

The routine the map does not show

Some of what the drop changes never gets written down. A stair street may cut down from the end of the lane, concrete steps between fences, the shortest way to the bottom on foot and no way at all by car. Coyotes use the canyon as a hall and the lane as a room. The first rain finds every swale the subdivision left behind. None of this is in the parcel report, which is why the contingency period exists: those days between opening escrow and removing contingencies are for pulling the parcel map, reading the title report slowly, asking the city for the permit history, and, if the slope shows a crack or a lean, paying a soils engineer before removing anything at all.

Where the record stops

The record does not say whether the retaining wall has steel in it or only goodwill. It does not say whether the slope weeps after the first rain, whether the neighbor's fence is over the line, how the house sits in smoke on a still September night, or whether an insurer will bind the policy this year. Those answers live in an inspection, in a geotechnical report, and in the memory of neighbors who have swept ash off the same porches for thirty years. The file tells you what the lot is. Only the block tells you what the lot is like.

One walk before you decide

Here is the gesture, and it costs an afternoon. Pull the ZIMAS report for the parcel and print it. Fold it the way the reader folded theirs, walk the lane in the last hour of daylight, find the stair street if there is one, and stand at the back fence long enough to see what the hill does with the wind. Then go home and read the report again, because the same fields say more with chaparral behind you. If a question survives the walk, send it in with a note in the margin. The drawer has room.
