Frequently asked questions
The channel takes most of it and the rest still reaches the houses. Why?
The Narrows concentrates what the channel cannot hold. A February cell is funneled through the gap and only partly contained, so the remainder arrives on 1950s pads downstream. Partial containment is still delivery.
The garage slab sweats along one side only. What does that indicate?
A pulse arriving underneath from the channel side. On a 1959 slab there is nothing to inspect, so the first sign is condensation on the wall nearest the water. One-sided sweating points at direction, not at humidity.
A 15-inch rancho year. Why does Whittier Narrows still flash the Rio Hondo into a 1959 plate?
Because it arrives as a flash the Narrows already concentrated. A 4.64-inch month on rancho alluvium is a shallow flood from the wash. Desert-year detailing does not survive a river that was paved into a channel.
