The project area includes Cypress Lane and Palmetto Lane. The map above shows the project limits highlighted in red.
Scope of Work
The scope of work for the ditch rehabilitation project includes:
Regrading and re-establishing of the roadside ditches
Replacing of the culverts and resetting them to match the flow line of the ditch
Replacing the driveway where the culverts are replaced
Increasing the capacity of any culverts less than 24 inches in diameter
Removing any unpermitted culverts or other encroachments in the City Right of Way.
Project Approximately on Schedule
I drove by the project earlier in the week and it appeared that the City had completed approximately a quarter to a third of the project in about a quarter of the time. That means they are on schedule or slightly ahead.
Ditch rehab already completed in Forest Cove
From the looks of things, it appears the City is doing exactly what it promised.

“The official hurricane season for the Atlantic Basin (the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico) is from 1 June to 30 November. As seen in the graph above, the peak of the season is from mid-August to late October. However, deadly hurricanes can occur anytime in the hurricane season,” warns the NHC.
Average Number of Storms
Source; NHC
In an average season, we get 11 or 12 named storms, six of which become hurricanes and two or three of which become major hurricanes (category 3 or greater).
Twelve storms would get you to the letter L. But so far this year, we’re already on the R storm. And we have three more months to go in the season.
Points of Origin Tend to Shift by Month
The NHC shows where hurricanes tend to form each month of the season. In the first ten days of September, more hurricanes form in the Gulf than at any other time. The NHC shows a whole series of charts like the one below. It’s interesting to see how they change from period to period.
Source: NHC. Sept. 1-10 and Sept. 11-20 show the greatest number of hurricanes forming in the Gulf.
Note how few storms formed in the Caribbean compared to the period from October 11 to 20.
Compared to September 1-10, note how many more storms formed in the Caribbean during October 11-20.
Track Probabilities Also Shift by Month
The NHC also shows an interesting series of charts that show track probabilities by month. September is the most likely month for storms to track through the Caribbean, into the Gulf and onward to the Texas coast.

In stark contrast, during October, storms are most likely to veer east toward Florida and the East Coast.
Strike Density on Western Gulf Coast

On the Texas Gulf Coast, Galveston has been hit more times than any other county. Harris, Brazoria and Chambers Counties follow closely.
Today’s Five Day Tropical Outlook
As if on cue, the NHC is now tracking seven tropical disturbances (as of 800 AM EDT Thu Sep 10 2020).
The two closest to Texas are highlighted in yellow above. That means they currently have less than a 40% chance of formation.
A large area of disorganized showers and thunderstorms near the Bahamas is forecast to move westward, crossing Florida on Friday and moving into the eastern Gulf of Mexico over the weekend. Upper-level winds are expected to become conducive for some development of this system while it moves slowly west-northwestward over the eastern Gulf of Mexico early next week. Formation chance through 5 days is 30 percent.
Another trough of low pressure has developed over the northeastern Gulf of Mexico and is producing a few disorganized showers and thunderstorms. Some slow development of this system is possible while this system moves westward and then southwestward over the northern and western Gulf of Mexico through early next week. Formation chance through through 5 days is even lower, at 20 percent.

San Jacinto River Authority (SJRA) will hold public meeting on Thursday, September 10, 2020, at 6:00 p.m., via webinar and telephone conference, to discuss its ongoing Lake Conroe Reservoir Forecasting Tool Project.
Accurately determining inflow during a flood theoretically lets dam operators determine how much water to release and when. That, in turn, helps protect properties both upstream and downstream to the extent possible.
Senior residents of Kingwood Village Estates trying to escape as Harvey’s floodwaters rose.
Additional Information
The Lake Conroe Reservoir Forecasting Tool Project addresses flood protection in the San Jacinto River Watershed.
One goal: to anticipate peak water level in Lake Conroe during rainfall events based on:
Weather forecasts
Observed rainfall
Lake levels
Other data.
A second goal: to predict peak release rates of stormwater from Lake Conroe.
The SJRA says this will help improve communication with Offices of Emergency Management and the general public during rainfall events.
SJRA expects completion of the project by early spring 2021. The Texas Water Development Board (TWDB) and SJRA have funded the project.

Editorial Comment
I, for one, hope they use their new Reservoir Forecasting Tool to release floodwater at safe rates, although that was not explicitly stated in the SJRA press release on the meeting. Releasing at safer rates may mean releasing water earlier or holding it longer to flatten peaks. In my opinion, SJRA should hold floodwater as high as they safely can…as long as they safely can. I hope this new tool helps SJRA do that.
I’d rather see floodwater in Lake Conroe than in Kingwood’s Town Center.

City Making Good Progress on Forest Cove Ditch Rehabilitation Project
In late July, the City of Houston’s Stormwater Action Team began a ditch rehabilitation project in Forest Cove. The City predicted the project would take until November 24, weather permitting.
The project area includes Cypress Lane and Palmetto Lane. The map above shows the project limits highlighted in red.

1108 Days after Hurricane Harvey
Today is Statistical Peak of Hurricane Season
According to the National Hurricane Center (NHC), today is the statistical peak of hurricane season in the Atlantic Basin.
Little Known Facts About Hurricanes: Peak of Season
The NHC has a fascinating page on hurricanes and climatology. Here are some interesting facts I gleaned from it.
“The official hurricane season for the Atlantic Basin (the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico) is from 1 June to 30 November. As seen in the graph above, the peak of the season is from mid-August to late October. However, deadly hurricanes can occur anytime in the hurricane season,” warns the NHC.

SJRA Considering Input on Lake Conroe Reservoir Forecasting Tool Thursday, 6PM
San Jacinto River Authority (SJRA) will hold public meeting on Thursday, September 10, 2020, at 6:00 p.m., via webinar and telephone conference, to discuss its ongoing Lake Conroe Reservoir Forecasting Tool Project.
Accurately determining inflow during a flood theoretically lets dam operators determine how much water to release and when. That, in turn, helps protect properties both upstream and downstream to the extent possible.
During Harvey, many felt that the SJRA released too much water too quickly – 79,000 cubic feet per second at one point. That, they say, flooded homes downstream unnecessarily when capacity still existed in the reservoir. Lawsuits are still working their way through the courts.
Many also complained about the lack of warning for the massive release which inundated homes as people slept.
