$25 Million Regional Stormwater Detention Facility Grant
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.
