Lauder Basin Phase II on Greens Bayou Under Construction
The long-awaited Lauder Basin Phase II on Greens Bayou is now under construction. In May of last year, the Texas Water Development Board announced a $2.2 million grant to expand the basin.
Then in September, HCFCD announced that construction would be starting “soon.” Harris County Flood Control District (HCFCD) estimated sometime in the fourth quarter of 2022.
Construction Photos Taken 5/7/23
A visit to the job site earlier this week showed that construction is now well underway. See the photos below.

Eventually, Phase 2 should have several compartments with water-quality plantings to help filter out pollutants, and a small stream connecting the ponds. This presentation is a bit dated, but shows HCFCD’s plans for the basin as they existed in 2020.
Together, Phases I and II should provide more than 1,200 acre-feet of stormwater storage. HCFCD designed them to fill up during storms to help reduce the risk of Greens from flooding local homes, businesses and schools. After a flood, the basins release excess water slowly when the channel can safely accept it.
Phase II (651 acre feet) will actually provide more stormwater storage than Phase I (588 acre feet).
HCFCD estimates total Phase II construction costs at $32 million and predicts construction could take 2.5 years.
Spending Comparison with Other Watersheds
Greens Bayou has received more than a quarter billion dollars of projects such as these since 2000. That’s more than any other watershed in Harris County with the exception of Brays Bayou – where Commissioner Rodney Ellis lives.
Greens Bayou is one of the few watersheds where HCFCD spending did not plummet last quarter. Even as spending decreased in 15 watersheds, it rose in Greens Bayou by almost $4.8 million. To put that in perspective, it increased 11 times more than the watershed with the second largest increase, White Oak, at $431,126.
Here are the actual numbers.
No doubt, the activity you see in the photos above had a lot to do with Greens’ ranking. So, does construction on Garners Bayou, a tributary of Greens farther downstream.
Stay tuned for more news as construction progresses.
