The Ditch She Buried for Curb Appeal Became a Flood Warning-Ginny

Wade Tillman had spent most of his adult life listening to water.

Not in a poetic way, although June sometimes teased him for making it sound like that.

He listened the way a mechanic listens to an engine, the way a doctor listens to a chest, the way a man listens when the thing in front of him can kill someone if he misunderstands it.

Water had habits.

It took the lowest path, punished arrogance, ignored speeches, and remembered every inch of grade that human beings pretended did not matter.

Wade learned that at Texas A&M before he learned it at TxDOT, and he learned it again in the Hill Country after every hard spring rain.

By 2019, when he retired as a senior hydraulic engineer for Region 17, he had signed his name to more flood control plans than most engineers would ever review.

His work covered Bexar, Kendall, and Medina counties, places where dry creeks could become brown rivers before coffee cooled in a mug.

The Tillman land outside Boerne had taught him first.

Forty acres of limestone, live oak, cedar, draws, and shallow channels had been in his family since 1886.

His great-grandfather had traded two rifles and a plow mule for the property, and Wade had grown up hearing that story as if it were scripture.

The front drainage channel was part of that scripture too.

His grandfather Cecil had planted a cedar near the property line in 1953, and for decades that tree watched over the ditch like a marker.

In 1992, after a bad flood took out the original cattle gate, Wade widened and stabilized the channel himself.

He did not do it because it looked pretty.

He did it because water had told him exactly where it wanted to go.

When Castle Ray Homes bought 312 acres adjacent to the property in 2005 and platted Cielo Vista Ranch, the ditch became more than family maintenance.

It became a recorded part of the subdivision’s survival.

The developer’s consulting engineer was a man Wade had mentored years earlier, so Wade reviewed the drainage plan for a case of Shiner Bock and the pleasure of clean math.

The math was simple and unforgiving.

Two hundred thirty-four new impervious acres of roofs, driveways, and streets would produce roughly 54 acre-feet of stormwater during a 10-year design storm.

That water needed a discharge path.

The natural path was the watercourse along the front edge of Wade’s property.

In April of 2006, the drainage easement was filed with the Kendall County Clerk’s Office.
