Katy Prairie Project Summary

The Katy Prairie once encompassed over a thousand square miles of Texan coastal plain west of Houston but the ecosystem has suffered severe degradation and now faces obliteration by the city’s relentless march.

The rapid growth has led to the Katy Prairie Stream Mitigation Bank (KPSMB) which was designed to service the compensatory mitigation needs of Harris County’s growing population of 6 million. Scaled to fit demand, KPSMB is the largest permitted stream mitigation bank in the United States.
