Alamo Heights Bioswales.

By Dorian Dégagé

Dry-creek bioswales that drink tens of thousands of gallons a year (modeled) and grow food out of what used to be the runoff. Drainage rebuilt as habitat — and a grocery line nobody has to pay twice for.

The limestone-lined dry-creek bioswale full of stormwater during a downpour in Alamo Heights — water held in the planted channel instead of the street

It does its best work in the weather everyone else complains about.

The read

The site had the affliction most lots share and few admit to: in a storm the water sheeted off in a hurry, took the soil along as a souvenir, and then the ground went bone-dry by August, righteously offended. The land was telling us, in plain language, exactly where it wanted to move water. The work was to listen — to slow it, sink it, and put it to use, rather than wrestle it to the curb and call that a victory.

Before · after

Same water. New address.

The street used to keep the storm — sheeting down the gutter, ponding at the curb, gone by August. Now the ground keeps it, and grows something on it.

Before — stormwater sheeting down the street gutter and ponding at the curb at the Alamo Heights site, with nowhere to soak in
Before. The storm ran the gutter and ponded at the curb — soil leaving, recharge zero.
After — a native sunflower and white wildflowers growing at the edge of the limestone-lined bioswale, water held in the planted channel
After. The same water, held in the channel — sunflower, frogfruit, and a food line where the runoff used to be.

What we built

Dry-creek bioswales — limestone-lined channels that catch and hold stormwater, absorbing tens of thousands of gallons a year (modeled) and persuading it to soak in rather than run off to be somebody else's flood. Then we planted the line in native edibles: persimmon, prickly pear, agave, muhly. The drainage doesn't merely manage water; it sets a table.

Limestone-lined, planted, and waiting on weather.

What it does

Three returns at once.

Water: tens of thousands of gallons a year (modeled) kept on site instead of exported downstream as someone else's emergency — recharge, not runoff. Habitat: a planted channel is a corridor, and pollinators and birds rarely turn down a good corridor. Food & body: native edibles draw people into the landscape to harvest — the Movement dimension of the Score, where a place you forage in quietly outperforms a place you merely admire.

"Held where it falls, stormwater is the cheapest irrigation you'll ever own — and the start of a food line. The storm drain never wanted it anyway."

The lesson

Waste is just a resource that wandered into the wrong room.

Stormwater is only a problem the moment you decide to send it away. Held where it falls, it's the cheapest irrigation going, the start of a food line, and a habitat besides — all of it conjured from the very thing the neighbors were paying good money to be rid of.
