that asked permission before crossing a fence. Warren had grown accustomed to specialists speaking confidently within minutes of arrival, so Renata's first afternoon unsettled him. She spent hours asking where a ditch used to bend, how often the creek had historically risen, and what changed when the development site was cleared.
"When are you going to tell me what happened?" Warren asked as she finished taking notes near the concrete outlet.
"After I've checked whether the story you're telling me matches the elevations," Renata replied. "A channel can look wrong without causing the whole problem, and a channel can look ordinary while sending water somewhere it shouldn't."
Casey followed her during the field visits and learned how much she had not known. Renata used surveyed elevations to trace likely flow paths, examined historic aerial imagery for drainage changes, compared the construction plans with what was actually built, and collected rainfall data from multiple stations rather than relying on memory of a storm. She wanted maintenance records for the old ditch and the developer's as-built drawings, documents that showed how the system functioned after construction rather than how an engineer originally imagined it. She also asked about the timing of every flooding event, including those that ended quickly and those that lingered.
The process took weeks. On some days the team went home without a result Warren could understand, leaving him to wonder how many hours of professional work he was paying for. Casey continued making measurements, but now her records fit into a larger model, and Renata showed her why a missing reading or an imprecise location could matter when two parties disagreed over a flow path. Gradually, Casey's fear of being wrong became more useful than confidence would have been, because it made her check every entry before relying on it.
One morning, Renata asked Warren to tell her about the flood he remembered most clearly from childhood. He described a spring when rain had fallen for three days and the creek crossed the road near the old church. The lower fields had held water then, but the water had arrived from the creek side and drained away as the channel fell. Renata asked whether he remembered the direction of the current near the willows.
Warren nodded slowly. "East," he said. "It ran east. Always east until the creek backed up enough to stop it."
Renata added the note to her timeline. The current direction alone did not prove liability, but it was consistent with the historical maps and with older photographs of the ditch. The new channel appeared to concentrate runoff from the development tract and deliver it toward the Puit boundary, increasing both the rate and duration of water entering the basin. Renata still needed to quantify the effect and distinguish it from the basin's natural tendency to hold water.
