I Am The Senior Vegetation-Risk Modeler At A 1.6 Million-Customer Utility, And At Ten In The Morning Two Weeks Before Fire Season I Pulled The Raw LiDAR Scores From My CPUC Depository And Saw That The High-Risk Spans I Had Scored As Priority-Trim For Two Seasons Running Had Been Pushed To Next-Season Status Under My Own Modeler Signature.

I am the senior vegetation-risk modeler at a 1.6 million-customer utility, and at ten in the morning two weeks before fire season I pulled the raw LiDAR scores from my CPUC depository and saw that the high-risk spans I had scored as priority-trim for two seasons running had been pushed to next-season status under my own modeler signature.

My name is Soledad Kline. I am a Professional Engineer and a Certified Forester. Deanna Pryor treated my LiDAR scores as engineering inputs that should accept a budget overlay—and she forgot the CPUC depository remembers what the overlay erased.

The GIS lab on the fourth floor of the Sacramento headquarters always smelled faintly of ozone from the server racks and stale coffee. I stood behind a junior modeler’s chair, watching his cursor hover over a three-dimensional point cloud on the dual monitors. The fan on his workstation hummed a steady, flat note.

“You are looking at the vegetation canopy, not the conductor,” I told him.

I reached down and tapped his spacebar to isolate the LiDAR returns. The screen shifted from a chaotic green mass to a stark architectural line intersecting a gradient map.

“Point-cloud classification separates the canopy from the hardware,” I said. “Then we run the catenary modeling.”

He leaned closer to the monitor. “Because the line moves?”

“A line doesn’t sit static; it sags based on thermal load and ambient temperature,” I said. “You have to measure the encroachment distance from the maximum sag point, not the resting state.”

I clicked his mouse to pull up Span 4112. The proximity score flashed red on the screen: 0.88.

“That is a priority-trim,” I said. “The oak canopy is actively invading the General Order 95 clearance envelope.”

I switched the view to an adjacent span. The score dropped to 0.21.

“Here, the clearance is twenty feet,” I said. “The model sees the difference physically. You just have to let it.”

I stepped back from his desk and pulled a flash drive from my pocket.

“When you finish the extraction, push the raw scores to your local drive,” I said. “I upload every raw score export to my own PE-license-credentialed CPUC ESCS depository.”

He looked over his shoulder. “Isn’t the internal server backed up?”

“It is,” I said. “It’s a habit from a job at a smaller utility in 2018 where the IT team rolled back the internal model server and we lost an entire season of scores.”

Two months earlier, I stood at the podium in a windowless ballroom at the Hyatt for the IEEE Power and Energy Society’s northern California chapter meeting. The air conditioning blew a steady, icy draft across the microphone.

The title of my slide deck glowed on the projector behind me: LiDAR-Derived Encroachment Modeling Under General Order 95 in Tier 3 Fire-Threat Districts.

The room held eighty utility engineers, state regulators, and fire-protection district chiefs. I walked them through three case studies of a model’s score chain.

“A raw LiDAR proximity score measures physical reality,” I told the room. “But if a reweighting formula is applied downstream, the published score can drift away from the raw measurements.”

I advanced the slide to show a side-by-side comparison of a raw scan and a modified output.

A CalFire division chief in the third row raised his hand. He wore his dress uniform. “In a post-fire forensic review, which score holds legal weight? The raw measurement or the utility-published Vegetation Management Plan?”

“The Vegetation Management Plan is what the utility formally submits to the state,” I answered in plain English. “If an ignition occurs on a span that the utility’s own raw LiDAR flagged as high-risk, but the published plan downgraded it, the liability centers on the justification for that downgrade.”

In the back row, the section chief for the CPUC Wildfire Safety Division uncapped a pen and wrote something down in a leather notebook. I clicked the remote and moved to the next slide.

Deanna Pryor did not always alter my data. Two years ago, she co-chaired the Women in Power Engineering employee resource group’s mentorship sub-committee meeting. The conference room smelled of catered pastries and whiteboard marker. I sat in the front row. Deanna stood at the front of the room, wearing a tailored navy blazer, addressing a dozen younger engineers.

“Data without interpretation is just noise,” Deanna said, resting her hands on the podium. “But interpretation without accuracy is a liability.”

She looked across the room and pointed directly to me.

“Soledad Kline is the only modeler at this utility who reads a point cloud the way an old surveyor reads a transit,” she said. “Pay attention to her process.”

The younger engineers turned in their chairs to look at me. I kept my expression neutral and nodded once.

When the meeting ended, the room began to empty. Deanna walked over to my chair. She reached into her blazer pocket and handed me a heavy, brass Women in Power Engineering challenge coin.

“Keep setting the standard,” she said.

I took the coin. It felt heavy and cold in my palm. I slid it into my briefcase.

That same year, I attended my first Western Reliability Council Regional Hearing. For ten years, those hearings have anchored the calendar. They always open at exactly 10:00 AM. At 10:00, the WECC reliability staff sits at the front tables in the Northern Region conference room in Folsom.

The coffee urns steam on the side credenzas. Ten in the morning has always meant one thing: the Regional Hearing opens, and grid reliability gets reviewed. It is the hour when the data becomes public record.

On a Friday afternoon, an email arrived from Mary Ostrowski, the emergency-management director for Trinity County. The afternoon light outside my window was dry and glaring.

Our county fire safe council is asking why three feeders along the Hayfork ridge that were red-tagged in your model two years ago haven’t been trimmed yet, she wrote. Anything I should know before our spring readiness exercise?

I read the sentence twice. I kept my hands on the keyboard. The keys were smooth and warm.

I typed a reply.

I will pull the trim roster.

I hit send. I did not pull the roster yet. I sat back in my chair and looked at the screen.

The Friday afternoon light in my home office in Redding cast a sharp, geometric grid across the hardwood floorboards. The air conditioning unit in the window labored against the rising heat outside. I opened my CPUC ESCS portal on the left monitor, authenticating with my state PE credentials.

I opened the utility’s as-filed Vegetation Management Plan PDF on the right monitor.

I scrolled to the Hayfork ridge Tier 3 spans.

My raw LiDAR scores in the depository for those spans ranged from 0.79 to 0.92. Highest priority.

The as-filed scores in the VMP PDF ranged from 0.34 to 0.41. Low priority.

I navigated to the VMP appendix. The methodology section defined a reweight formula applied to the raw outputs: “tree mortality lag-adjusted.” The signature at the bottom of the filing was Deanna Pryor’s.

I pressed the palm of my hand flat against the warm aluminum top of my laptop. The metal was heating up from the dual processors running the rendering engine. I closed the laptop. I walked outside into the dry, late-afternoon light.

The Weaverville ignition happened at the end of the 2024 fire season, a sudden flare of dry grass and manzanita that caught the wind before CalFire bombers smothered it in retardant. It was a small event, a warning rather than a disaster, and no structures were lost.

The post-incident review took place in the main conference room at the Sacramento headquarters. The room had floor-to-ceiling glass that looked out over the Capitol Mall. I sat at the long table, the heavy leather chair squeaking slightly whenever someone leaned forward to look at the projector screen.

Deanna led the review. The internal investigation had concluded that the feeder that sparked the fire was on the utility’s planned-trim-but-deferred list. Deanna stood near the screen, paging through the mitigation slide deck.

“We need to review our encroachment scoring methodology to better integrate budget realism,” Deanna told the room, her voice steady and professional. “The field contractor cannot trim every span we tag. It is operationally honest to adjust our modeling.”

I listened to her present. I pressed my thumb against the cold steel edge of the conference table. I did not understand what that recommendation operationally meant at the time. I thought she was talking about refining the algorithm for future scans.

When the meeting adjourned, I left the room and drove the two and a half hours back to my home office in Redding, the Central Valley stretching out golden and flat beside the highway.

Now, I understood what budget realism meant.

I went back inside the house. I opened the laptop.

I pulled eight quarters of Vegetation Management Plan filings from the portal. Two full fire seasons.

I ran a script to compare the as-filed PDFs against my raw LiDAR score exports from the ESCS depository.

The pattern was not a quarterly artifact. It was systematic.

There were 2,114 Tier-3 spans across the Klamath-Trinity corridor that had scored above 0.7 raw. Every single one of them had been reweighted to below 0.5 in the as-filed VMPs. The reweight had been continuous. Consistent.

Deanna believed the reweight methodology was a defensible engineering accommodation that integrated budget reality with risk scoring. She did not use the word ‘deferral’ internally.

She called it ‘budget realism scoring.’ She believed I was a senior modeler working exclusively from the utility’s internal model server, oblivious to the fact that my PE license tied my name to an independent CPUC ESCS depository where the true scans lived.

On Saturday morning, I packed my Professional Engineer field kit: the Trimble GPS, a laser range finder, my hard hat, and my camera.

I drove out to the Hayfork ridge. It was a hot, dry early-spring afternoon. The dirt access road was rutted and washed out in sections. I pulled my utility truck off State Route 36 and parked near a rusted cattle gate.

I put on my hard hat and walked along the public road right-of-way toward the utility easement, stepping carefully over the dry brush. The smell of warming chaparral, baked earth, and dry pine needles rose off the forest floor in thick waves. The cicadas were loud enough to form a wall of sound.

I stopped at Span 4471. The wooden utility pole stood bleached and splintering in the sun.

I raised the range finder to my eye and targeted the conductor, then targeted the nearest live oak canopy.

The digital readout flashed: 3.8 feet.

The line was a 21 kV conductor. General Order 95 Rule 35 minimum clearance for that voltage class is four feet. Ten feet preferred.

The live oak and madrone branches were visibly swaying inside the clearance envelope. The encroachment was active.

I lifted the camera. I composed the frame with the encroachment in the foreground and the sagging conductor in the background. I pressed the shutter button.

I took three exposures. Each photograph was GPS-stamped and date-stamped.

I walked back to the truck. I drove back to Redding through the dry afternoon light, the suspension of the truck rattling over the washboard dirt road.

When I returned to my home office, I set the camera on the desk. My eyes caught the edge of the second bookshelf.

The heavy brass Women in Power Engineering challenge coin sat there, exactly where I had placed it two years ago. The embossed lightning bolt on its face caught the light from the window.

I looked at it.

I did not move it. I did not turn it face-down.

I sat back down at my desk and woke up the monitors.

I opened my calendar.

Tuesday morning. 10:00 AM.

The WECC Regional Hearing in Folsom.

PacifiNorth Power was on the agenda as the lead presenter for vegetation management readiness heading into fire season. Deanna Pryor would be at the front of the room. I was scheduled right beside her as the utility’s modeling Subject Matter Expert.

The same 10:00 that had always meant nothing more than the routine opening of the Regional Hearing was now the exact hour that the deferral pattern for 2,114 spans was scheduled to receive a formal reliability endorsement.

Ten in the morning had weight now. It was the hour my PE stamp was meant to legitimize two seasons of manufactured budget realism.

I closed the VMP comparison window.

I exported the eight-quarter raw-versus-filed dataset to an encrypted USB drive.

I uploaded the GPS-stamped field photographs to my PE-license CPUC ESCS account.

I opened the CPUC Wildfire Safety Division Emergency Mitigation Petition portal.

I did not call Deanna.

I did not call the Chief Vegetation Officer.

I filled out the petition form line by line. I attached the raw scores, the reweighted filings, and the three photographs.

At 23:08 on Sunday evening, I clicked submit.

The portal generated a case-number receipt. I printed the single page.

I folded it once and slid it into the front pocket of my field binder.

I stood in my kitchen in Redding at 06:48 AM on Monday, waiting for the coffee maker to finish its cycle. My phone vibrated against the granite counter. The screen illuminated the dim room with a new email notification. The sender was Deanna Pryor.

I opened the message.

“Saw the WECC agenda – I’d like you to walk through the model methodology section personally tomorrow,” she wrote. “The CPUC WSD liaison is on the briefing line and a credentialed modeler voice closes the methodology question for the council. Should be a great morning – I’ll buy you breakfast in Folsom.”

I read the text twice. I poured my coffee. I had roughly twenty-seven hours to make a choice. I would either stand at the front of that conference room and serve as the credentialed endorsement for a deferral pattern covering two thousand spans, or I would trigger the CPUC Mitigation Mandate before 10:00 AM.

I carried my mug to the window. I saw the signs two years ago. I chose to believe her. When the first quarter’s Vegetation Management Plan dropped a few dozen Tier 3 spans into the next season, I told myself it was an anomaly.

A temporary budget true-up for contractor mobilization. I noticed the methodology change in the VMP appendices—the new “tree mortality lag-adjusted” phrasing—but I dismissed it as standard executive jargon.

I gave her the benefit of my doubt because she had handed me a challenge coin and called my work the gold standard in front of my peers. I watched the deferred high-risk spans climb from fifty, to five hundred, and finally to two thousand one hundred and fourteen, and I let my silence act as a signature on her budget overlays.

At 11:42 AM, my laptop chimed. An automated message arrived from the CPUC Wildfire Safety Division portal.

Emergency Mitigation Petition Received.

The status line read: Pending Review. It contained no human context. It did not confirm if the Emergency Mitigation Mandate would be approved. It did not confirm if they would serve it before the 10:00 AM readiness vote on Tuesday. The risk remained entirely open. If they did not act in time, my petition would become a post-mortem document rather than a preventative mandate.

I drove down to the Sacramento headquarters that afternoon at 14:30 to pick up the final WECC presentation credentials. Deanna’s corner office was immaculate. It featured a seamless glass wall facing the Capitol Mall. Four separate Wildfire Resilience Award plaques were mounted above her mahogany credenza.

I walked in while she was on the phone with the SVP of Operations. She motioned for me to sit in the leather guest chair. She was completely relaxed.

“Yes, the rate-case update is solid, and we’ll keep the seasonal trimming budget within the cap we committed to,” Deanna told the SVP.

She picked up a silver pen from her desk and twirled it slowly between her index and middle finger.

“Soledad Kline is on the methodology block tomorrow,” Deanna continued, smiling across the desk at me. “She’s our strongest modeler and her PE stamp closes the CPUC WSD question on scoring.”

I kept my feet flat on the carpet. I did not break eye contact.

“She is being a good sport about jumping in,” Deanna said, her tone casually dismissive. “And the WECC reliability staff appreciates hearing from the actual modeler rather than just the executive.”

She ended the call. She set the silver pen down. She handed me a glossy presentation folder containing my WECC badge and the finalized slide deck. She did not ask about the Hayfork ridge data. She did not ask if I had reviewed the VMP appendices. I took the folder. I left her office without saying a word.

On Tuesday morning at 09:18, I walked through the double glass doors of the WECC Northern Region building in Folsom. The morning air was already hot enough to radiate off the asphalt parking lot. I carried my heavy field binder in my left hand.

The encrypted USB drive was secured in the bottom of my bag. The printed CPUC case-number receipt was folded sharply inside my jacket pocket.

I stopped at the security desk. I handed the guard my state identification. He scanned it and printed a visitor badge. I clipped the plastic sleeve to my lapel. My hands were perfectly steady. I bypassed the elevators and took the stairs to the second floor.

At 09:48, I stepped into the main conference room. Twelve minutes before the hearing officially opened.

The room was a long rectangle dominated by an oak conference table. The air conditioning hummed loudly over the low murmur of early conversations. The CPUC WSD liaison’s face was already visible on the large video link monitor mounted in the corner.

Deanna sat at the lead presenter’s chair at the front of the room. She had her laptop open, the slide deck loaded and projected onto the main screen behind her. She looked up from her keyboard and saw me walk through the door.

She raised her hand and waved me toward the empty SME chair beside her.

I walked to the front of the WECC Northern Region conference room. The room smelled of industrial carpet cleaner and roasted coffee. A massive regional transmission map covered the entire back wall. A long oak conference table dominated the center of the space.

The WECC reliability council staff sat at the head of the table. The North Coast county emergency-management directors filled the chairs along the left side. PacifiNorth executive leadership sat along the right.

Deanna Pryor sat in the lead presenter’s chair. Her laptop was connected to the room’s AV system. Her slide deck illuminated the main projection screen. The side monitor displayed the active video link with the CPUC Wildfire Safety Division.

I took the empty Subject Matter Expert chair beside Deanna. I set my field binder flat on the oak table. I kept my hands folded in my lap. In the back row, a CalFire division chief sat as a silent observer, wearing his green uniform.

At precisely 10:00 AM, the WECC reliability staff lead tapped his microphone.

“We are calling the Tuesday session to order,” he said. “The primary agenda item this morning is the formal review and endorsement of PacifiNorth Power’s vegetation management readiness for the upcoming fire season. A successful endorsement today locks in the utility’s current Vegetation Management Plan.”

Deanna stood up. She smoothed the front of her blazer.

“Thank you,” Deanna said to the room. “PacifiNorth has aggressively optimized our trimming roster this year. We have applied a rigorous budget realism overlay to our LiDAR models, ensuring we meet our fiscal commitments in the rate case while maintaining absolute grid safety across the Klamath-Trinity corridor.”

She clicked to the next slide. A map of the Tier 3 districts appeared. It was color-coded. The red priority lines were sparse. The green deferred lines stretched for hundreds of miles.

“Before we take the readiness vote, our senior vegetation-risk modeler, Soledad Kline, will walk you through the engineering methodology that confirms these spans are safe to defer,” Deanna said.

She gestured toward me. She smiled.

I did not stand up. I did not open my binder. I looked at the clock on the wall.

It was 10:07 AM.

The heavy wooden double doors at the back of the conference room swung open.

A man in a dark suit walked into the room. He wore a state agency badge clipped to his belt. He carried a thick stack of manila folders. He did not pause at the visitor chairs. He walked directly down the center aisle toward the lead presenter’s chair.

The WECC reliability staff lead leaned toward his microphone. “Excuse me. This is a closed regional hearing.”

The man stopped at the front of the oak table. He looked up at the video link monitor. On the screen, the CPUC WSD section chief nodded once.

The man turned to Deanna. He set the stack of manila folders on top of her printed slide deck.

“We have a regional readiness presentation in progress with CPUC WSD on the line,” Deanna said. “Whatever this is can wait until after the readiness vote.”

The man did not move his hand from the folders.

“CPUC Wildfire Safety Division has issued an Emergency Mitigation Mandate under PU Code 8389 and GO-95 Rule 35,” the senior wildfire safety officer said. “The mandate is effective immediately.”

The room went completely still. The hum of the air conditioning seemed to amplify.

Deanna looked at the seal on the top folder. She slowly turned her head toward me. The smile was gone from her face.

“Soledad. What did you do,” Deanna said quietly.

I did not lower my voice.

“I filed an Emergency Mitigation Petition Sunday night,” I said. “The reweight on the Klamath-Trinity Tier 3 spans across two seasons does not match the raw LiDAR scores in the CPUC ESCS depository.”

Deanna placed her palms flat on the table.

“Budget realism scoring is a defensible engineering accommodation,” she said. “The deferred spans are managed through PSPS and hardening.”

I opened my field binder. The rings clicked sharply in the quiet room.

“Span 4471 on the Hayfork ridge has live oak branches 3.8 feet from a 21 kV conductor,” I said. “GO-95 Rule 35 minimum clearance is 4 feet. I photographed it from the public road right-of-way Saturday at 14:18. The encroachment is active. PSPS does not change that.”

Deanna shook her head. Her jaw muscles flexed.

“A single span photo on a weekend ride-along is not a basis to override a quarterly VMP,” Deanna said.

I turned the page in my binder. I pushed the eight-quarter dataset across the oak table toward her.

“Two thousand one hundred and fourteen Tier 3 spans reweighted in the same direction across eight quarters,” I said. “The reweight signature on every VMP is yours, Deanna. The raw scores in the depository are signed against my PE license. You weren’t on the Hayfork ridge Saturday. I was.”

Deanna did not speak. She looked at the spreadsheets.

“The CPUC ESCS depository holds the raw LiDAR scores on my PE-license credential, the reweight signature on the VMPs is yours, and the GPS-stamped field photographs from Saturday show live encroachment within the GO-95 envelope on three of the deferred spans,” I said.

The WECC Northern Region reliability staff lead had been holding his pen over his readiness checklist. His fingers stopped moving. He set the mandate packet on the table. He stood up. He walked to the regional map on the back wall. He did not look at Deanna for the next two minutes.

Mary Ostrowski sat on the left side of the table. She had been taking notes in her readiness binder. She closed the binder. The snap of the cover was loud. She picked up her phone. She dialed a number and began making a call to the Trinity County Fire Safe Council. She did not return to her seat.

In the back row, the CalFire division chief had been leaning back in his chair. He leaned forward. He pulled his phone from his pocket. He photographed the slide deck on the screen. He stood up. He walked the perimeter of the room without speaking, then took a different seat with his phone open.

The CPUC senior officer tapped the mandate folder.

“PacifiNorth’s General Rate Case decision is conditioned upon a pending corrected VMP filing,” the officer said to the room. “The California Public Utilities Commission is referring this to the penalty investigation unit under PU Code 2107.

Two thousand one hundred and fourteen Tier 3 spans are placed on a twenty-one-day mandatory trim window. The readiness endorsement vote is foreclosed.”

Deanna gathered her presentation packet. She stacked the papers. She straightened the edge of the binder against the oak table, tapping it twice to align the sheets.

“I have managed grid maintenance through five fire seasons on this corridor and not one ignition originated from a span on my deferral list,” Deanna said.

She did not wait for a response. She picked up her phone. She walked out the conference room side door without looking at me.

The heavy door clicked shut behind her.

The CPUC senior officer pulled a field notebook from his inside pocket. He clicked his pen. He noted 10:14 on the top line.

I sat at the table. I closed my field binder.

The light coming through the window of my home office in Redding had turned the color of dry-season haze. It was late Tuesday afternoon. The wall air conditioning unit rattled and hummed, working to cool the small room. If I opened the window, the smell of warm cedar from the porch outside would flood in, carrying the heat with it. I kept the glass shut.

On the second bookshelf, the brass Women in Power Engineering challenge coin sat exactly where it had always been. I did not look at it for long. My heavy field binder lay open on the desk where I had set it down when I returned from Folsom.

The clock on the wall above my door read 16:38. Ten in the morning had already happened today, and it did not happen the way it has happened for ten consecutive years. The WECC hearing did not endorse PacifiNorth’s readiness.

The CPUC Wildfire Safety Division Mitigation Mandate was sitting on the oak table in the Folsom conference room. I looked down at the open field binder on my desk. I turned the pages until I reached the Saturday Hayfork ridge photograph.

Span 4471 was perfectly clear in the glossy print, the live oak reaching 3.8 feet from a 21 kV conductor in the foreground. Below the photograph, I had clipped the CPUC WSD case-number receipt.

The two pages sat next to each other on the desk in the late-afternoon light. Ten o’clock used to mean nothing more than the routine opening of the Regional Hearing. Today, ten o’clock meant the hearing that was about to endorse a massive deferral pattern did not endorse it, simply because I had stood inside the same hour with a different file open.

I did not celebrate. The two seasons of my own name printed on the as-filed Vegetation Management Plans remained in the public record.

The emergency mandate required the utility to trim two thousand one hundred and fourteen spans in twenty-one days. The grid could not support that level of sudden, concentrated contractor activity without de-energizing the lines for safety. Starting tomorrow, planned four-hour Public Safety Power Shutoff rotations would begin across the Klamath-Trinity corridor. They would last for one calendar month.

Twenty-three thousand ratepayers across three counties would experience scheduled outages during peak late-spring hours. St. Bernardine Medical Center, a small rural hospital in Trinity County, would have to run on its diesel generators for four hours during one of those outages, burning through sixty percent of its standby fuel before the contractor restored the feed. A family in Hayfork, the Bertollis, would lose an entire freezer of elk meat and dairy during a six-hour shoulder-of-day shutoff.

My Professional Engineer signature still appeared in the public CPUC Wildfire Safety Division docket alongside two seasons of as-filed VMP submissions. The docket does not delete. My name would always be attached to the false budget overlays, a permanent digital record that required an emergency petition to correct.

Deanna Pryor would not apologize to me. The utility would not issue a statement acknowledging that I had acted to protect the grid.

Deanna thought the model and the budget were two different conversations she could have on different days. She forgot that the LiDAR scores I write are signed against my PE license, and that the encroachment on a Hayfork ridge does not move because a budget cap moved in the rate case.

I opened the bottom drawer of my desk.

I took out a fresh field log. It was the same brand I always used, with the same waterproof grid pages. I opened the cover.

I took my pen. I wrote today’s date in the top right corner.

On the first line, I wrote: Klamath-Trinity Mitigation – CPUC Cycle – Day 1.

I set my pen down in the gutter of the spine. I looked out the window at the dry air. The blank lines waited.
