SHELL’S DOWNTOWN OPERATIONS TO SHED OFFICES, SCURRY OVER TO LARGER WEST HOUSTON CAMPUSES One Shell Plaza Office Tower, 910 Louisiana St., Downtown HoustonMore than half a decade after the local fretting about it started, Shell has announced that it will leave One Shell Plaza, writes Cara Smith this morning. Moreover, the company will drop nearly all of its other Downtown holdings as well, including the previously announced removal of recently-ish acquired BG Group from BG Group Place. Smith writes that the only announced exception to the pullout is Shell’s trading group at 1000 Main; the rest of the company’s downtown workers will move by early 2017 into either the Technology Center at Hwy. 6 south of Richmond Ave. or into the company’s Woodcreek campus along I-10 (south of the Addicks reservoir).

Barker Clodine Rd. in Barker Reservoir, Houston, 77084

A reader caught the view above during a lunchtime bike ride into the Barker reservoir yesterday. The shot shows the nearly submerged stop signs on the currently-closed road barricade where Barker Clodine Rd. merges into the hike-and-bike trail system running throughout much of the reservoir (which stretches between I-10 and the Westpark Tollway just west of Hwy. 6). The Corps of Engineers has been releasing water from both Barker dam and its sister reservoir Addicks across I-10 since Thursday — but the level behind the dams continued to rise for a few days as additional water drained into the basins from the surrounding watersheds, faster than that water could be safely released downstream into Buffalo Bayou.

Both Barker and Addicks reservoirs’ levels finally began dropping on Saturday — though both started filling again briefly on Sunday as water from later-in-the-week storms trickled east from the surrounding watersheds. Below is an up-to-date look at Barker reservoir’s change in storage since the Tax Day flood, per USGS measurements:

Addicks and Barker
04/22/16 3:30pm

A water-watching reader sends some south-facing photos from yesterday evening (right) and last October, comparing views over the fenceline of the 400-ft.-wide diversion channel at the northern edge of the Addicks reservoir. The channel picks up most of the flow from Langham and Horsepen creeks where they join up as they flow south into Addicks. The 400-ft.-wide floodway was dug in the 1980s; the flow usually lurks down in the narrow channel seen in the shot on the left.

The scene above is less than a mile east of Bear Creek Village, where water is now moseying into neighborhoods from the western edge of the reservoir (and washing some wildife and livestock around). The Army Corps of Engineers has been releasing water from both Addicks and Barker dams to minimize the pooling (and relieve stress on the dam structures themselves) — but those releases have to be done slowly enough to avoid causing additional flooding downstream along Buffalo Bayou. Meanwhile, water is still flowing into the reservoirs from western watersheds; the measured levels behind the 2 dams topped all previous water level records and normally allowed pooling limits in the reservoir by Tuesday, and has been rising since. Here’s a shot of water gushing out through some of the gates of the Barker dam this afternoon:

Potential Flood Map, Bear Creek, Houston, 77084

The Army Corps of Engineers will begin releasing water from the Addicks and Barker dams later this evening; nonetheless, water levels in the reservoirs are still expected to rise high enough to cause street flooding in the Bear Creek subdivision north of Clay Rd. The Corps also notes that nearby residential areas should anticipate that wildlife inhabiting approximately 26,000 acres of forested land in the 2 reservoirs may flee the rising water and enter nearby neighborhoods. That wildlife may include the feral pigs previously targeted by Harris County Precinct 3’s trapping-and-foodbanking program; sightings of animals such as deer, coyotes, and bobcats have also been reported in the reservoirs.

Harris County Flood Control District has published a list of streets that could be impassible for days or weeks due to flooding, as well as a few maps (one of which is shown above). Here’s the other map below, highlighting in pink the streets south of Addicks Satsuma Rd. and Langham Creek expected to get water when the level in Addicks reaches 103 feet:

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:

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.

Proposed West Houston Mobility Plan Major Thoroughfare Plan

Proposed West Houston Mobility Plan Major Thoroughfare PlanThere’s a rather bold new plan for 2 of the Houston area’s major parkland reserves hiding in an image included in an almost-final draft of the West Houston Mobility Plan being prepared by the Houston-Galveston Area Council for submission to TxDOT. A new roadway connecting Briar Forest Dr. to Highland Knolls Dr. through the heart of 7,800-acre George Bush Park is shown in a proposed major-thoroughfare plan for the area. (See segments in blue in image above.) A segment of Baker Rd. is also shown linking to the new parkway. And north of I-10, a similar major roadway is seen connecting Hammerly Rd. to Patterson Rd. — through the Addicks Reservoir.
