Northpark Overpass Groundbreaking Announced

Today, Houston Mayor Pro Tem Dave Martin announced the groundbreaking for the Northpark Drive Overpass Project. Weather permitting, it will happen Thursday, April 13.

It took months to acquire right-of-way for the project. Northpark Drive will expand from four lanes to six. And it will include a bridge over Loop 494 and the Union Pacific Railroad Tracks.

Groundbreaking During Mobilization

The Lake Houston Redevelopment Authority (LHRA)/Tax Increment Reinvestment Zone 10 Board has awarded a contract to Harper Brothers Construction for the project.

The ceremonial groundbreaking will actually happen during the mobilization phase. In coming weeks, residents can expect to see the contractor pre-positioning equipment, supplies, and materials for construction.

Finally, an Elevated Evac Route over Railroad

The Northpark Drive Overpass Project will alleviate congestion, enhance accessibility, and increase safety in the Kingwood area. The 2015 Kingwood Area Mobility Study, commissioned by TIRZ 10, concluded this project is critical to ensuring public safety.

Local leaders have worried for years about evacuating Kingwood in the event of a natural disaster or chemical spill during a derailment, similar to those that have made headlines around the country lately.

The first phase of this project will go from I-69 to the Kingwood Diversion Ditch

A second phase, not yet approved, will extend to Woodland Hills Drive and include elevated bridges over the Diversion Ditch and Bens Branch.

Each phase will take approximately two years, according to the LHRA. Work will begin near I-69 and move east. The City is only breaking ground on the first phase at this time.

The project promises multiple benefits:

  • Better traffic flow, less congestion
  • Improved emergency access/egress.
  • Improved drainage that meets new post-Harvey Atlas-14 requirements.
  • Wider pedestrian walkways.
  • Enhanced lighting and landscaping.
  • Elimination of center ditch.

TIRZ Meetings Open to Public

Safety Considerations during Construction

Once construction commences, please be aware of flagmen and orange traffic cones that will be put in place on-site to help with traffic flow through the construction zone as the project may require a one-lane closure. Two-way traffic will be maintained at all times. Businesses and residents will have access to driveways and sidewalks at all times and may experience an increase in noise levels due to trucks and equipment in the area.

For a detailed traffic plan during construction, residents can view the plans here (pages 43-163).

As a reminder, TIRZ Board meetings are open to the public and held on the second Thursday of each month at 8:00 a.m. Visit the LHRA website for more information on the Northpark Drive Overpass Project and view the 2023 Board of Directors Calendar.

Please contact the District E office by phone at (832) 393-3008 or by email at districte@houstontx.gov with any questions or comments.

2046 Days since Hurricane Harvey

Rainfall Predictions Increasing, City Lowering Lake Houston

New forecasts that show higher than previously predicted rainfall amounts for the next three days have caused the City to begin lowering Lake Houston.

Widespread 3-6 Inches Expect, Higher Isolated Totals

All week long, meteorologists have predicted heavy rains starting on Wednesday, 4/5/23, through Friday, 4/7/23. This morning, guidance from Harris County Meteorologist Jeff Lindner indicated that the rainfall could be even heavier than previously predicted. Instead of widespread 2-4 inches, Lindner now predicts widespread 3-6 inches. Last night, ABC13 predicted up to a foot of rain in isolated places, especially north and west of US59, i.e., the San Jacinto Watershed.

Three day totals predicted by the National Weather Service on 4/5/23

Lake Lowering Began at Noon

As a result, the City of Houston began lowering Lake Houston today at noon.

According to Mayor Pro Tem Dave Martin, Houston Public Works, Coastal Water Authority, and San Jacinto River Authority have worked together closely over the last 24 hours to monitor local forecasts. Based on this morning’s forecast within the San Jacinto Watershed, the City decided to open the floodgates on the Lake Houston Spillway Dam.

Property owners should make arrangements to secure boats and other items along the shoreline.

City of Houston

Houston Public Works will keep the flashboard and tainter gates open throughout the inclement weather and Coastal Water Authority will continue storm operations allowing the inflow to pass through Lake Houston until the weather threat concludes.

SJRA NOT Lowering Lake Conroe Level

SJRA has confirmed they will NOT lower Lake Conroe. This will maximize the City of Houston’s lake-lowering efforts.

Atmospheric Squeeze

An approaching low-pressure system from the northwest will stall when it encounters a high-pressure system over the Gulf.

The two fronts will funnel moisture from both the Pacific and Gulf between them. That’s because in the Northern Hemisphere, high-pressure systems rotate clockwise and low-pressure systems rotate counterclockwise. So atmospheric moisture will be squeezed between them along a steady line for days. Think of meshed gears.

Because of dry grounds, moisture that falls during the first day will likely soak in. But after that, runoff rates will increase.

The areas receiving the most rainfall will likely be north and west of Houston, because that’s where the frontal boundary will likely linger longest.

Flooding Outlook

Street flooding will be a concern through Friday. 

Says Lindner, “Smaller creeks, rural watersheds, and San Jacinto River system will be the most vulnerable to higher run-off flows. While widespread creek and bayou flooding is currently not expected, some watersheds may experience significant rises and a few locations potentially to flood levels. Any sustained training of heavy rainfall over any certain watershed for an extended period of time could result in flooding. It will be important to monitor rainfall amounts and locations through the period for any significant watershed responses.

Watch the following watersheds closely: Willow Creek, Little Cypress Creek, Cypress Creek (and Waller County tributaries), Spring Creek (and Montgomery/Waller County tributaries), Bear Creek, South Mayde Creek, Cedar Bayou, East/West Forks of the San Jacinto River, Keegans Bayou, Clear Creek, Halls Bayou.

2045 Days since Hurricane Harvey

Woodridge Village Excavation Surpasses 100,000 Cubic Yards

In the four weeks since my last update, Harris County Flood Control District’s (HCFCD) contractor has excavated another 11,000 cubic yards of dirt from Woodridge Village. That means Sprint Sand and Clay has removed a total of 104,000 cubic yards since it started work under its Excavation and Removal Contract a little more than a year ago.

Sprint is removing the dirt from what will become a sixth stormwater detention basin on the former Perry Homes site. The lack of adequate detention capacity on the site contributed to flooding hundreds of homes in Kingwood twice back in 2019, before HCFCD purchased the property.

New Excavation Already Second Largest on Site

Already, at 62 acre feet, the new basin ranks as the second largest stormwater detention basin on the 268-acre site. Woodridge Village’s five original basins had the following capacities:

  • N1 = 13.2 acre feet
  • N2 = 154.7 acre feet
  • N3 = 42 acre feet
  • S1 = 18.6 acre feet
  • S2 = 42.5 acre feet

The new detention basin could more than double capacity on the site. Ultimately, it will exceed Atlas 14 requirements.

Here’s where the original five are located.

Locations and sizes of first five stormwater detention basins shown in blue.

The new basin will go between N2 and S1.

Progress by the Numbers

The 11,000 cubic yards excavated in the last 28 days averages 2,750 cubic yards per week. That’s an increase of 220 cubic yards per week compared to the previous month. It’s also 1,000 cubic yards per week more than the weekly average since the start of the contract.

The current monthly rate more than doubles the minimum required under Sprint’s contract.

The excavation of 100,000 cubic yards marks yet another milestone. Sprint has now removed more than 20% of the 500,000 cubic yards allowed under the contract.

February vs. March Photos

To get a feeling for just how much 11,000 cubic yards is, compare these photos taken at the ends of February and March.

End of March: excavation stretches much farther into the distance.

A Head Start on Construction

In December 2022, HCFCD revealed the results of its analysis of alternatives to reduce flooding adjacent to Woodridge and Taylor Gully. HCFCD is now working on finalizing those plans.

Excavation and removal contracts give HCFCD a head start on construction while engineers finish plans. This compresses the timetable.

The contract also saves taxpayers money. It gives Sprint the right to remove up to 500,000 cubic yards for a grand total of only $1000. Sprint makes its money by selling the dirt at market rates to home- and road builders. The only restriction: the dirt can’t be placed in the floodplain.
