TxDOT has been doing some circling around over the thoroughly soaked Brazos River valley this week grabbing a few snapshots, including some taken yesterday morning as 31 East and Central Texas counties picked up flood-related disaster declarations from the governor’s office. Running north-to-south (right-to-left) under the murky waters shown above is FM 723 in Rosenberg, TX; you can spot the bridge rising up to cross the river’s normal channel on the left side of the photo, while SH 36 stretches away to the northwest.
Flash- and non-flash flood warnings are in effect around the region through at least Friday night, depending on how intense the rest of this week’s predicted downpours turn out to be. Meanwhile, the already-feet-past-the-previous-record flood gauge at nearby Richmond, TX, is still creeping upward this morning toward 55 ft.:

Dozens of roads are still closed this morning following yesterday’s heavy storms to the north and west. The National Weather Service 
A press release from the city notes that 
“St. Augustine grass has a very shallow root system that barely reaches 2 inches into the soil. Beneath that root system is our typical thick clay gumbo soil that is very slow to drain moisture and more prone to let water run off into the storm sewer system. When you plant native grasses and plants, the roots reach down much deeper in the soil and fundamentally change the [bulk] composition of the soil. Instead of the thick gray clay gumbo soil, you get a much looser brown soil that

“Since much of the development inside the Loop is done over existing impermeable surfaces, it would seem to me that the majority of the additional demand on our bayous is coming from the large greenfield production builders further upstream. My intuition is that the amount of building going on out there most likely dwarfs what’s occurring inside the Loop (can anyone find numbers on this?). And what’s really fueling all that development is the billions of federal, state, and local tax dollars going [toward] expanding and enlarging highway construction all over the place. By reducing the time/cost of commute, they serve as enormous incentives enabling building and selling more cheap houses further away from the employment centers closer to the city. In a nutshell, that is the sprawl Houston is famous for and I think the main source of our flooding woes. There’s no easy answer since we all want cheaper houses — but someone pays for that, somewhere.” [
