Tom switched off the vacuum. "How many houses did this hit?"
I had been about to ask him the same question. He named the Walshes on Hickory Lane, the Patels two houses farther down, Glenn Crawford, Donna Boyd, his own property, and mine. A few minutes later his wife brought out a notebook in which she had recorded dates neighbors called asking to borrow pumps or fans. She had been collecting more useful information than she knew.
The Walshes had lost carpeting for a second time. Donna's furnace had taken water and needed professional inspection before it could operate safely. Glenn had spent years moving storage boxes from one end of the basement to the other, trying to find a place that would stay dry. Every family had received a different explanation from the HOA: gutters, landscaping, cracked foundations, insufficient homeowner maintenance.
"Brenda's yard was dry," Tom said. "I drove past on my way to get another pump. Not a puddle."
I did not answer immediately. Her property sat high beside the retention area, and the trench's alignment began near the rear of her fence. That did not prove she had directed the work. The coincidence was worth investigating, not turning into an accusation I couldn't yet support.
Tom studied me. "You're thinking it."
"I'm thinking somebody needs to explain why this pipe exists. We need evidence of that, not a guess about who held the shovel."
He nodded. "What do you need from me?"
"Names, photographs, dates, and permission from the affected owners to look at their damage. If they want to help, we can put the history together. But we don't pressure anyone, and we don't tell people things we haven't proved."
That night I spread the original stormwater drawings across the kitchen table. The pond was supposed to release water at a controlled rate into an easement running along the development's eastern boundary. My new photographs suggested a separate connection that bypassed the intended route and sent additional flow toward the low lots. I ran preliminary calculations using measured slopes, recorded rainfall, and the available pipe dimensions, then marked every assumption for independent confirmation.
I sat there until two in the morning. The house was silent except for the hum of the dehumidifiers downstairs. Emma had left a drawing beside my computer showing our house under a large blue cloud, with a little arrow labeled THIS WAY pointing away from the basement and toward the street. She had drawn the runoff path more sensibly than whoever had cut the trench.
Below the picture she had written, in uneven letters, We should all get to be dry. I taped it above my desk, not as evidence for an inspector, but as a reminder of what all the numbers meant. The equations would be necessary to win the argument. They would never be the reason I started it.
