road-closures-4-21

Replacement work on the Yale St. bridge over White Oak Bayou now won’t start until the 25th, according to an update from TxDOT. The original planned construction start drifted past in the middle of Monday’s deluge; no changes have been mentioned yet for expected 2018 reopening date.

Meanwhile, TxDOT’s Yoakum office says it’s keeping an eye on US 59 in Wharton County to the southwest of town, though that highway is not closed at the moment according to the agency’s interactive mapping system (pictured above). The map shows areas of road closures, flooding, and construction, with written descriptions for each site clarifying which lanes are affected, by what, and how badly. Zooming in further gives a clearer picture of the extent of some of the closures — below is a view of west Houston, showing the stretch of Hwy. 6 near the Addicks reservoir that could be closed for the next 4 to 6 weeks:

April 18th drone views over Martin Circle Dr., Porter, TX 77365

A glimpse behind some northern fencelines comes by way of drone from G.A. Eblen, who took to the Porter sky by proxy to catch these shots of planned and impromptu retention ponds in action. The Monday-morning photos center east of 59 around the Briar Tree Court subdivision — up in the right hand corner of the south-facing shot above are the well-moistened sports fields of White Oak Middle School.

Rectangles of forested land are mixed in with angular subdivisions and potential subdivisions-to-be in the suite of surveying shots.  Here’s the view north over FM 1314, toward the Family Dollar Store and Executive Inn & Suites (on the left, below):

A NEW FLAG FOR FLOOD CITY Armadillo rescued during 4/18 floodsWrites Cort McMurray of Monday’s flooding: “This week’s ‘historic’ rainfall (shake it off, TV weather people: if it happens once, it’s historic. If it happens every single year, it’s just rain) gave us the perfect symbol. You’ve seen it — it’s all over the Internet. Somewhere in our Xanadu on the Bayou, an intrepid Houstonian was spotted, knee-deep in rainwater and soaked to the skin, a yellow slicker hanging haphazardly on his shoulders, surrounded by flooded cars and floating debris, toting a waterlogged armadillo to safety. That’s it. That’s our new flag. Because wherever you live in this far-flung metropolis, you know what it feels like to be soaked to the skin and up to your knees in rainwater, carrying a stranded armadillo to safety. We’ve all been there, haven’t we? It’s the closest thing we have to a universally Houston experience.” [Houston Chronicle] Photo of armadillo rescued from Greens Bayou: Doug Miller

A few folks at the Halstead apartments surveyed the scene along Brays Bayou late yesterday morning, catching sight of all kinds of action in the water. The video above captures the part of the lonely journey of an unmoored porta-potty floating away from the site of the under-construction Starbucks on the former gas station corner next door; the trip was also also tracked from further upstairs in the complex, where another photographer was documenting the flood:

What’s In The Water?
04/19/16 11:00am

A scattering of drones took to the air across Houston yesterday as the rain slowed to do some sight-seeing around the brand new 9-county disaster zone declared by governor Abbott in the afternoon. Filling up during floods is standard operating procedure for Buffalo Bayou Park, as demonstrated prior to the park’s first planned official opening last spring. That’s not part of the sanctioned protocol for all of Houston’s bayou corridors, but it’s hard to argue about it in the moment —above is the overhead view of Brays Bayou venturing out into broader Meyerland.

More footage comes from northwest Houston, circling around White Oak Bayou at N. Houston Rosslyn Rd. in Inwood Forest —  west and downstream of some the areas that got the most rainfall:

CITY WATCHING ADDICKS AND BARKER DO THEIR OWN DAM THING addicks-april-18The US Geologic Survey’s tracking of water collecting at the Addicks reservoir this week shows water levels jumping about 28 feet since yesterday morning, in the preliminary data graphed above. Both Addicks and Barker reservoirs, which function in large part as parkland when not busy storing potentially billion of gallons of floodwater, feed out into Buffalo Bayou near Hwy. 6 at Westheimer Dr. through dam outlets listed as extremely high risk structures by the USACE. The city’s Twitter account noted this morning that the Addicks dam was under municipal scrutiny; the Office of Emergency Management tweeted this afternoon that the stretch of Hwy. 6 and N. Eldrige Pkwy. running through the Addicks reservoir may be closed for a few days while the area drains.

Harris County FWS channel map, April 18, 2016

The many exclamation points scattered across the map of Harris County above mark spots where stream channels are currently overtopping their banks (in red!) or potentially thinking about it (in yellow!). The capture comes from the Harris County flood warning system interactive map, which automatically updates data from its county-wide network of rain and flood gauges every 5 minutes. Most of the current overtopped locations are concentrated toward the northwest areas of the county, parts of which got more than 17 inches of rain since Sunday morning. The green shapes mark channel gauges that aren’t currently at spillover stage or close to it (whether or not any spillover occurred earlier today).

The county’s online map also shows cumulative rainfall across the area — here’s what the totals look like across town for the last 24 hours:

While all bus and rail service is currently on hold due to widespread flooding, the route 66 bus stop sign on White Oak Dr. is still bravely performing its signaling duties (lower left above) as water from White Oak Bayou rushes past. A reader sends several studies of the area around Stude Park at the Taylor St. bridge at the southern edge of the Woodland Heights area; here’s a few more shots of the White Oak Bayou greenways gone brown this morning, with I-10 in the background to the south:

Flooding along S. Braeswood Dr., Meyerland, Houston, 77096

Here’s this morning’s view north across S. Braeswood Dr. between Chimney Rock and Hillcroft in Meyerland, where Brays Bayou has once again been feeling out some alternate route options. That’s the Congregation Beth Israel synagogue and the closed-for-the-day Shlenker School across the water on the northern bank, looking higher but not that much drier; current reaadings for the nearest upstream county gauge show nearly 8 inches of rain over the last 12 hours, with higher totals further west. That hasn’t stopped some folks from checking things out from close-up:

COMMENT OF THE DAY: WHAT IS AND ISN’T RISING IN THE MEYERLAND FLOODPLAIN McMansions and McMoat“Last night I rode my bike over to an area of Meyerland that I kept seeing listed in the Daily Demolition Report (this is the pocket just south of S. Braeswood, west of S. Post Oak). It was worse than I imagined. Many houses have been removed. Many others are still standing but vacant. A few have been rebuilt or are in the process of being rebuilt — these are all 2-story ‘McMansions’ and elevated. Visually, it’s a weird looking place. The new houses stick out because of their scale to start with, and putting them up on pedestals next to empty lots exaggerates the effect. When the floods come again, they will be surrounded by a giant McMoat.” [Memebag, commenting on Comment of the Day: Where Houston Stayed Underwater After the Memorial Day Flood] Illustration: Lulu

COMMENT OF THE DAY: A PROCLAMATION OF DRY TERRITORY FROM THE KING OF THE HILL Flooding Coastal Homes“There actually are a few places in Houston that have never flooded and never will, due to strange and highly-localized factors. My house is one of those. I am up above the Hwy. 288 pit between 59 and Brays Bayou. Even during the worst floods, when cars were floating down there, the water would have had to come up another 25 feet, completely filling the pit with God-knows-how-many acre-feet of water, before my street would have been under water. Even then, the water would have had to climb another 5 feet up the hill in my front yard to reach my elevated house. This protection is a combination of close proximity to a huge man-made sink, the elevation of the grade of my lot when my house was constructed, and restrictions upstream that cause flooding in Meyerland but more-controlled flow downstream because of the upstream pinchpoints.” [Superdave, commenting on Comment of the Day: Where Houston Stayed Underwater After the Memorial Day Flood]

COMMENT OF THE DAY: WHERE HOUSTON STAYED UNDERWATER AFTER THE MEMORIAL DAY FLOOD Flooded Home“Was there ever any kind of press writeup on why so many homes in Meyerland did not come back from this last flood? I’m saddened by all the vacant lots, and on some streets off Endicott, there are clusters of teardowns. Was insurance plus flood insurance essentially useless for all of those homeowners? Or was it the new city building requirements? Genuine questions, because I’ve been in the area 30 years and this [flooding] seems to have been so much more devastating than Allison (and Ike).” [Heather, commenting on Daily Demolition Report: As Is, Where Is] Illustration: Lulu

Screen Capture of Addicks and Barker Dam Construction Updates Map

The Army Corps of Engineers is holding a public meeting amid this evening’s predicted thunderstorms to chat about the recently begun replacement work on the Addicks and Barker dams, which have each won the rare and highly distinguished label ‘extremely high risk’ through a combination of structural issues and close proximity to Houston. For those not planning to flood the Corps with questions and comments in person, there’s a somewhat-outdated online survey, as well as an online map of updates on the project’s progress. Work to replace the outlet structures of the dams began in February, and is expected to take about 4 years. 

The 2 reservoirs, spread out across 26,000 acres on either side of the Katy Fwy. near Highway 6, starred in the Sierra Club’s 2011 lawsuit over the construction of Segment E of the Grand Parkway through the reservoirs’ catchment area. The club claimed development spurred by the road could send major additional runoff to the reservoirs, increasing the chance of dam failure, which Dave Fehling of Houston Public Media reports “could do an estimated $60 billion dollars in damage to downtown Houston, to industries along the Houston Ship Channel, [and] even to the Texas Medical Center.” The judge didn’t stop construction of Segment E, but did order new studies on its potential flooding impacts.

Predicted Before and After Flood Map, 500 Year Flood Event

That’s Galveston Island going for a dip in the before-and-after captures above, from a set of interactive timelapse maps released by the Texas Tribune and ProPublica yesterday (along with several articles by authors Kiah Collier and Neena Satija). The new maps model flooding across the Houston region during Hurricane Ike — as well as what would have happened if Ike had actually hit just south of Houston, as meteorologists initially expected.

The maps are your chance to relive an old disaster, or to see how many of your neighbors you can take out with a hypothetical-but-not-unrealistic future storm: users can pick between Ike, south-er Ike, a storm 15% stronger than Ike (nicknamed Mighty Ike), and a modeled 500-year storm (which the article suggests may actually be a concern on the every-few-decades-or-so level; ‘500-year’ has always meant ‘a low probability in any year’, and climate change is shaking up old modeling assumptions). The graphics also include a few dramatic face-offs:  Mighty Ike and the 500-year storm VS. 2 of the miles-long multi-billion-dollar coastal protection projects being studied for the upper Texas coast.

You can even search for your home address in the map system to see what flood levels might look like in your own back yard. Here’s what the maps show happening to the Clear Lake, Seabrook, and League City areas at the peak of the 500-year storm model’s storm surge, which the article says is a “not if, but when” event:
