Countywide master drainage plan identifies 17 flood problem areas
Waller County
Summary
Two big drainage moves: buying into Kane Island's detention ponds for three road projects at ~8% of cost, and a $5.1 million state-grant-funded regional detention facility on the old airport property with the Brookshire-Katy Drainage District. As the fastest-growing county in Texas, flood control is getting expensive attention.

The developer says roughly a quarter of the site is detention and discharge stays at predevelopment rates, but a resident pressed for the full drainage plan in writing.
