Hidden in Plain Sight • Episode 14 • Seattle, Washington

What Happens When Seattle’s Hidden Stormwater Systems Fail?

A ride-along beneath the surface of the city with The Peoples Gardening Collective — where drainage, flooding, contamination, and infrastructure problems become visible.

Featured Company: The Peoples Gardening Collective

Hidden in Plain Sight: the systems beneath our homes, businesses, and streets that most people never notice — until something goes wrong.

The Hidden Reality

Most people never think about where water goes once it disappears underground. But the systems beneath homes, businesses, streets, and landscapes can determine whether water is safely managed — or whether it becomes a flooding, contamination, or structural problem.

In this episode, Local Service Legendz rides with Bret and the team from The Peoples Gardening Collective to see what happens when those hidden systems are poorly designed, improperly connected, or simply overwhelmed.

What We Found

Drainage With Nowhere to Go

Storm drain collecting runoff on a wet street during Local Service Legendz Episode 14 about hidden stormwater systems.

At one property, runoff from the street, rear, and sides of the site had no clear side-sewer connection. Water was collecting around the structure, including near a block stem wall sitting in wet conditions.

A Backflow Risk Most People Never See

A seemingly ordinary hose connection created a potential siphon risk. Without proper backflow protection, contaminated water can be pulled toward a drinking-water supply.

When Stormwater Becomes a Basement Problem

At another stop, stormwater tanks and site conditions were connected to a larger flooding problem. The basement had taken on roughly four inches of water, showing how quickly hidden infrastructure issues can move indoors.

Building the System From the Ground Up

On Mercer Island, Faye Williamson and the PGC crew showed the construction side of stormwater work — compaction, rock placement, retainers, large fasteners, and the physical details that make the system function.

The Bigger Picture

This story is bigger than one property. In a region where stormwater and combined sewer systems intersect with dense development, contaminated soils, and heavy rain, small failures can create larger environmental and financial consequences.

Bret shows soil conditions that help explain why stormwater design has to account for what is happening beneath the surface.

One project. A much larger system.

700 million

Bret’s closing point is about scale: one property may seem small, but thousands of individual sites collectively shape how a city handles stormwater.

One of the solutions explored in the episode is a lined rain garden designed to keep stormwater out of contaminated soil while slowing its discharge into the combined sewer system.
