On Wednesday afternoon the Dobbins dairy lot in Laveen looked the way she had left it two weeks earlier: flat, cracked, the concrete lid of the old manure sump buried under a mound of loose dirt that had slumped as if it had rained, though it hadn't. The builder's stake still stood at the lane, a two-by-two with a red-painted top and a laminated tag. BM-2. PAD 1047.20.
Mateo was already there, sitting on the tailgate of his truck with his level on its tripod beside him, like a man who had been waiting a while and wanted her to know it.
"I set up before you got here," he said. "I didn't want you holding the rod on this one."
"Good."
He shot the stake top, then the dirt at its foot, then walked the rod out to the mound and shot the native ground beside the lid three times, because he was careful and because he was angry. He read the numbers out to nobody.
"Stake top's design pad. Ground at the stake is forty-six under it. Ground at the lid is forty-four under it." He wrote them on the back of his hand with a pen, the way apprentices do before anyone teaches them to use a field book. "So the lid's eighty-five from the dirt and one thirty-one from a floor that doesn't exist yet."
"Yes."
"You knew that when you filed."
"I knew it at eleven-forty yesterday. I filed at eleven fifty-two."
"Twelve minutes." He capped the pen. "My number's been in your phone the whole time."
She said nothing. He was right, and nothing she could say was shorter than that.
"I countersigned Dobbins. I read one thirty-one at the hole and I didn't round it, and afterward you told me that was the best thing I did all month. This morning I get a ping from the board. A correction I didn't file, on a basis I didn't choose, moved a record with my license on it from in to out. Your name's in the requester line. Mine's nowhere except the miss."
"The correction doesn't score countersigners."
"The column shows who signed." He looked at her for the first time. "You listed yourself. Two known, do not exempt. That was brave. You didn't list me. I'm the other half of one of your two."
The wind moved the laminated tag on the stake. Somewhere past the lane a pivot sprinkler on the alfalfa next door ticked through its arc, throwing water at a field that would be pads by spring.
"I should have called you before I pressed it," she said.
"Would you have waited if I said wait?"
She thought about it honestly, because he deserved the honest answer. "No. I'd have waited an hour so you could read it. Not longer."
"An hour's fine. An hour's all I wanted. I'd have told you to file it." He started breaking down the tripod. "The stake's wrong. The stake was always going to be wrong. It's a promise about dirt nobody's delivered. I'm not angry at the stake. I'm angry nobody told me which floor I was standing on until the board did."
On Thursday at 06:40 the coffee maker was on its second pass, because the first had been mostly air. She had propped the tablet against the fruit bowl, telling herself she wouldn't read it before she ate, and then read it.
The technical seat had posted at 05:30. The seat posted at that hour when it wanted something read before the day began.
GROUND TRUTH CORRECTION GT-2048-11-17-088: GRANTED. PRESENT-GRADE DEPTH ADDED. BM-1 DEPTH RETAINED. PRECEDENT REVIEW: 19 EVENTS. 16 RE-SCORED FROM PRESENT GRADE (SURFACE SHOT IN FILE). 3 MARKED DATUM-ONLY, NOT SCORED. 31 LINKED RECORDS. 12 MOVED IN TO OUT. 9 MOVED OUT TO IN. 10 UNCHANGED.
Twelve out and nine in. She had half expected the corrections to fall mostly her way. They fell every way, and that was how she knew the seat had done it honestly.
The Tolleson lateral had moved from out to in. That was Lateral 14-W, the buried irrigation pipe the district had disowned and Joaquín's orange tape had found. Its event had been measured from the district's old canal-bank mark, and the bank had lost the better part of a meter to wind and graders since the mark was set. Scored from the bank, her seal had missed by half a meter. Scored from the dirt she had walked, it was in. The board put her at ninth.
Below the seat's post was something she hadn't seen before. The contractor agent that had dug Lot 88, the one that filled field 7 off the pin, had changed how it posted. Its summary for a closure in Avondale, at 02:12, had two lines where there used to be one.
COVER 1.10 M BELOW GRADE (PERMIT DATUM). COVER 1.10 M BELOW PRESENT GRADE (SURFACE SHOT AT EXPOSURE). DIFFERENCE 0.00.
Difference 0.00. Somebody at the contractor had read the precedent flag, or the agent had read it on its own, and decided it would rather post a zero than become the next event in somebody's correction request. Ysabel's two-finger note had turned into a field in one night.
Then she opened the title agent's pane for the bank's sale of Lot 88. She could read it because she was a party now. There was a new line on the buyer's disclosure checklist, in the same pale grey as the others.
FILL HISTORY: PRESENT GRADE ~0.49 M ABOVE 1987 PERMIT DATUM (CLOSURE FIELD NOTES). IMPORTED FILL, ORIGIN UNKNOWN. GEOTECHNICAL REVIEW: REQUIRED BY LENDER POLICY 7.2.
She put the tablet face down, then picked it up and read it again. The coffee maker beeped, and she let it. A sentence about how deep a tank was had become a sentence about dirt nobody could account for, and the dirt belonged to a bank that wanted the lot sold by Christmas.
At 08:15 she was southbound on I-17 in the slow lane, behind a water hauler with a dripping valve, when her phone showed a contact she had saved on Tuesday as YSABEL TANK.
"Did you see the checklist?" Ysabel said. No hello.
"Fill history. Geotech review."
"The title agent called my office at seven. Not the agent. The person behind it, a woman named Brennan. Very polite. She asked whether my field note on Lot 88 was required by the closure plan. My office said no. She asked whether a note the plan doesn't require could be withdrawn as surplus. My office said they'd ask me." Road noise on her end too. "I'm asking you."
"It's your note."
"I know it's my note. I typed it with two fingers in a trailer. I want to know what it's for. Brennan says a geotech review on undocumented fill takes six weeks and costs four thousand dollars, the buyer's lender will walk, the bank relists after Christmas at a discount, and she'd like to know who that serves."
Lourdes watched the drip from the hauler's valve lay a dotted line down the lane.
"It serves whoever buys the lot and pours a footing into half a meter of fill with a soda can in it," she said. "And the next sealer. And it's true. The fill's there whether the note is or not. If you strike it, the board still has the correction, the correction cites photo fourteen, and photo fourteen shows the tan line. You can't strike the photograph without striking the dig."
"So striking it does nothing."
"It does one thing. It makes your file disagree with the board. The next time somebody pulls a closure you dug, they'll check whether your notes survived the sale."
Ysabel was quiet for so long that Lourdes thought the call had dropped under the Indian School overpass.
"Brennan said one more thing," Ysabel said. "The bank has no objection to the depth. Only to the word 'imported.'"
"Then tell her the word is yours. Tell her what you saw: tan fill on darker native ground, with asphalt and a can in it. If she wants to call it something else, she can hire someone to dig it and look."
"You're not going to tell me what to do."
"No. I'm the one who can't measure her own dig. I'm not going to edit yours."
Ysabel laughed, short. "Read by Y. Montaño."
"Read by Y. Montaño."
"Okay," Ysabel said, and hung up without saying which way she meant it.
The Monterosa job was the first paid walk the dispatch agent had sent her since the board moved her to ninth. It was a vacant duplex lot in Encanto between two that weren't vacant. The lender wanted a sealed interval on an old septic tank that the county thought had been abandoned when the street went onto sewer in 1962. The permit card said four feet to the lid, measured from "grade."
Before she opened the case she took the hammer out of the truck, drove a masonry nail flush into the curb face at the lot's front corner, and painted the head orange. She shot the nail against the dirt at the property line, at the middle of the lot, and at the back fence where the old clay pipe was supposed to run. She wrote the three differences in the log before the gravimeter was out of its foam.
118 DATUM: NAIL, CURB FACE, NE CORNER (ORANGE). LOT SURFACE AT TIME OF WALK: NAIL −0.12 / −0.15 / −0.31. ALL DEPTHS IN THIS RECORD FROM LOT SURFACE AT POINT OF READING.
She had never put a datum line on a seal of her own, and neither had anyone else. There had been no field for it until Tuesday, and there still wasn't. She typed it into the notes pane, which the board would hash with the seal whether or not it ever read the notes.
The back fence was nineteen centimeters lower than the front. The lot sloped a little toward the alley, and somebody had also scraped the back half when the duplex came down. She could see the blade marks in the caliche where the old slab had been.
The gravimeter took its usual eleven minutes to settle in the heat, the leveling bubble creeping in under its glass while a grackle walked the back fence and complained about her. She read a grid of twelve stations, four by three, two minutes each, and looped back to the nail at the start, the middle, and the end to check the drift. The anomaly was small and real: a low of minus nine microgals centered a meter and a half off the back fence. That was about what a two-thousand-liter tank of mostly air would make, at a depth the forward model put between 0.9 and 1.6 meters below the scraped dirt.
Four feet was 1.22. From the front of the lot. From the dirt under her boots at the back, it came to a meter and three.
She didn't open the permit layer yet. She logged the check first, 0.8 to 1.8, the way the rule she had argued for said to, and the board hashed it at 11:47 before she let herself see anything else. Then she opened the layer and read the card again. Four feet from "grade," in 1962, and the grade was the front yard of a house nobody had seen in ten years.
She sealed 0.9 to 1.5 from the dirt at the back fence, and added to the datum line: PERMIT GRADE PRESUMED FRONT OF FORMER STRUCTURE. NOT VERIFIED. At 12:10 she walked back to the truck and didn't look at the board to see what it thought.
She stayed parked at the Monterosa curb with the orange nail in the side mirror and opened the Dobbins event. The seat had re-scored it from the only surface shot in the file, one the builder's site agent took in August when it set the stake. Mateo's three readings from yesterday were better: the same lid, taken on a day the board was paying attention, by someone with a license, three times.
They weren't hers. She had held nothing. She had stood at the tailgate while he set up so she wouldn't touch the rod, and he had written the numbers on the back of his hand.
The event had a supplement button. Any party could attach a survey. The form wanted one submitter.
If she submitted, the readings went in faster. She was the requester on the precedent, the seat knew her name now, and anything with 118 on it landed in the queue Corral read before lunch. It would also put her name, again, on his numbers, on a record where his license appeared only on the miss.
If he submitted, they went in tomorrow or Monday, behind whatever the seat read first. They went in under the license of the man who had read the lid at 1.31 and not rounded it, and then read the dirt at 0.85 and not rounded that either.
She knew which was right. She also knew the second way cost her nothing but speed, and that she had wanted the speed, a little, because Dobbins was the record that had moved her down.
She typed to Mateo.
Your three shots from Dobbins should go on the event as a supplement. Your license, your submission. I'll add a line under it saying I was present and didn't hold anything. If you'd rather I submit, say so and I will, with your name as the one who measured. I'm calling you in an hour either way, before I touch it.
She read it over, took out "should," put it back, and sent it.
Then she set a sixty-minute timer on the dash, because she had said an hour, and because yesterday at the tailgate he had told her an hour was all he had wanted. The tablet chimed once, the board posting her Monterosa seal as received and unscored, waiting on a dig nobody had scheduled. Out the window the orange nail head caught the sun at the curb. It was a floor she had driven in herself, and it would outlast the sale, the geotech review, and probably her license. The timer read fifty-nine. She did not start the engine.
