New data shows the 100-year rainfall for this area has increased 4-5 inches since the NOAA study in 1961 or 2-3 inches since the USGS study in 2004. This is why flood mitigation and reducing sedimentation are so important. Basically, what we used to think of as a 100-year storm is now almost a 25-year storm.
NOAA Atlas 14, Volume 11: The New Go-By for Everything Related to Rainfall
Today, the Hydrometeorological Design Studies Center of the NOAA’s Office of Water Prediction released updated precipitation frequency estimates for Texas.
They are published as NOAA Atlas 14 Volume 11: Precipitation-Frequency Atlas of the United States, Texas.
The new precipitation frequency estimates supersede the NOAA estimates published in 1961, 1964, and 1977, and the USGS estimates published in 2004. The new NOAA estimates include data from Harvey and all of the huge storms we have had since 1994 including Tropical Storm Allison, the Tax Day Flood and the Memorial Day Flood. Here’s what the 100-year/24-hour rainfall map looks like. Note that the Houston to Beaumont area is in the bulls-eye.
The new 100-year 24-hour Rainfall Intensity Map. Accompanying documentation, describing the data used in this project and project methodology, will be published in December 2018.
Zooming in on the Houston area shows that the new 100-year 24-hour rainfall for the Lake Houston area is between 17 and 18 inches depending on your exact location.
First, select your location in the map, then click on the gage nearest you.
Next, review the rainfall table associated with that gage. Clicking on the other tabs or “print” brings up additional information.
Then review the new data for different time periods and recurrence intervals. This may be the information you want to keep handy for ready reference.
Comparison to Previous Studies
From this data, we can see that – for the gage at the San Jacinto and US59 – the new, official 100-year rainfall is 17.3 inches in a 24-hour period.
Compare a previous dataset published. Look on page 58 for the 100-year/24 hour data from 1961. Twelve inches in 24-hours represented the old 100-year rainfall for our area for decades.
USGS also published a precipitation frequency study in 2004. See the USGS Rainfall Maxima Guide for Texas (Warning: 40 meg PDF). I believe it became the basis for the current flood-plain maps redrawn after Tropical Storm Allison that were released in 2007. It shows the 24-hour, 100-year rainfall to be about 13 inches.
How New Data Will Be Used
What does it mean that the 100-year rainfall has increased 4-5 inches?
First and foremost, it means that all of the floodplain maps will be revised. One expert I talked to suspected that the new 100-year floodplain could be close to where the 500-year flood plain is now. However, that is far from certain and not official.
Floodplain Maps
The flood plain maps have not yet been redrawn, as Matt Zeve, Harris County Flood Control Director of Operations, discussed at the September meet of the Lake Houston Area Grass Roots Flood Prevention Initiative. The next step is for the County to process the new rainfall data in a new 2-D model that the Flood Control District has developed with new high-resolution LIDAR data. Contour internals in the new models will shrink from feet to inches. The LIDAR data also reflects new conditions in the watershed (developments, road expansions, siltation in ditches, etc.), so predictions should become much more accurate.
Insurance
Based on the new rainfall data, flood insurance rates could also change.
Construction
Finally, the new data will become crucial in city planning, construction and permitting. The City is already demanding that new construction be raised to two feet above the 500-year flood plain. Perhaps Mayor Turner had a hint of what the new numbers would show when he suggested the new construction standards.
Infrastructure
The larger rainfall totals also mean that cities must use larger storm drains and sewers in new developments. Everything will change.

Analysis of Montgomery County real estate tax records reveals wide inconsistencies in the way sand mines are appraised. Fifty three parcels of land in Montgomery County devoted to sand mining received seven different real estate tax classifications. Not one classification had anything to do with mining, though one parcel was classified as commercial land and two were classified as industrial.
Sand Mines on East and West Forks of the San Jacinto are appraised seven different ways from Sunday.
36 West Fork Mines Received Six Different Classifications
Sampling 36 parcels of land used for sand mining on the West Fork of the San Jacinto revealed that properties were taxed as:
A1 – Residential Single Family (1)
D1 – Qualified Ag & Timber Land (6)
E3 – Other Improvements over 5 acres Non-Ag (1)
E4 – Vac Rural Land over 5 acres Non-Ag (24)
F1 – Commercial (real) (1)
F2 – Industrial (real) (2)
The numbers in parentheses represent the number of parcels found within each category. The sample included West Fork mines larger than 5 acres from US59 to just west of I-45 on the San Jacinto River’s West Fork that showed clearly visible mining activities on the Montgomery County Appraisal District website.
17 East Fork Parcels Classified 3 Different Ways
Yesterday, I posted about one San Jacinto East Fork/Caney Creek mine in Porter that was subdivided into 17 different parcels. The parcels were classified as:
D1 – Qualified Ag & Timber Land (10)
C1 – All Vac Res Lts & Vac Res Tr < 5 Ac (3)
E4 – Vac Rural Land over 5 acres Non-Ag (4)
Real Estate Tax Roulette?
Altogether, the East and West Fork parcels represent a sample size of 53. Excluding undeveloped land reserved for expansion, several things stood out.
Sometimes adjacent pieces of land that were being used in identical ways received different classifications.
Areas dedicated to mining – often without any agriculture or timber – received ag/timber exemptions that dramatically lowered their taxes.
None of the parcels appeared to be vacant, yet 27 parcels out of 53 (more than half) were classified that way.
NOT ONE parcel of the 53 received a G3 Category classification for sand mines.
Not One Parcel Classified as “Subsurface Interests”
The G category in Texas Property tax includes “Real Property: Oil and Gas, Minerals and Other Subsurface Interests.” The Texas Property Clasification Guide states on page 10, “… real property defined as mines and quarries, should be reported as Category G3.”
The Texas State Controller’s website states: “Tax Code Section 23.01 requires … the same appraisal methods and techniques be used in appraising the same or similar kinds of property.”
Yet 53 parcels of land in Montgomery County devoted to sand mining received seven different classifications, not one of which had anything to do with mining.
Financial Impact of Inconsistencies
So how big of a deal is this? Yesterday, we saw the value of an ag/timber exemption compared to land classified as C1 and E4 on the East Fork. The actual tax due for the ag/timber land was $1.83 per acre. But the tax due on other land not receiving the exemption was $102.36 – 56 times more!
Today, I discovered similar inconsistencies on the West Fork.
JR Development paid $37,764.34 on 568 acres classified as vacant rural land (E4). The tax equaled $66.49 per acre or 36 times more than land with the ag/timber exemption.
For that land zoned as commercial, Scottie McDonald paid $2,180.18 on 22.1427 acres for tax/acre of $99.00. That’s 54 times more than land with the ag/timber exemption.
I still need to investigate this more. Is there a policy in Montgomery County NOT to classify mines as mines? Why are subsurface interests being given away? Did the State do away with the G3 classification?

I wish I could get a deal like this! A cardiologist from Nacogdoches named Dr. Prabhakar R. Guniganti (in a trust set up for his family members) owns virtually all the land used for sand mining adjacent to Kingwood on Caney Creek, White Oak Creek and the East Fork of the San Jacinto. Here’s the best part! The land isn’t taxed as industrial land. It’s taxed as agricultural and timberland, even though:
Almost half of the land does not appear to be used for agriculture or timber any more, and hasn’t been for quite some time.
Among other stringent requirements, State and County guidelines say that if a parcel is clear cut, it cannot go without replanting for more than two years to quality. The guidelines also state that both timber and agricultural land must be used at an intensity comparable to the surrounding area. Additionally, timberland must be used with the intent to produce income from timber and be devoted principally to the production of timber.
Guniganti is not alone; I’m just using him and his trust as an example. Several of the sand mines on the West Fork are also taxed at the same agricultural/timber rate.
$241 in Tax on Ten Acres
I found one 10-acre parcel of Guniganti land that owed a whopping $241.09 in real estate tax for 2017. Deal of the century! It hasn’t had any timber on it for about three years and Montgomery County is still assessing it as timberland for 2018.
Cross-check the information against the Montgomery County Tax Assessor/collector’s website. The two sites don’t always agree, but the assessor issues the actual tax bills, so for the purposes of this analysis we’re using the assessor’s info when computing taxes paid.
When I clicked on Guniganti’s 10-acre parcel as discussed in Step 2 above, here’s what I found. A little gray box popped up describing the location and size, plus the owner’s name. In this case, Guniganti no longer owns the property himself; he sold it to a trust in his family’s name, Guniganti Family Property Holdings LLC (limited liability corporation). LLCs are a common strategy that land owners use to insulate themselves from liability that may arise from use of the property.
The blue box shows the boundary of the ten acres within the mine. Clearly, there is no timber on this land and it is part of the mine.
Clicking on “View property information,” tells you the classification of the property, tax rates that apply to it … and the history of ownership, Note that Guniganti bought this parcel in 2014 and sold it to his LLC in 2017. Also note that, despite the sale, the market value of the property is assessed at $0.00 and its agricultural market value is also assessed at $0.00.
.
Because the Montgomery County appraiser classifies this parcel as “Timber,” the County, emergency services, the hospital, college, and school districts will have to split up a grand total of $241.09.
Of course, the land originally contained timber. Montgomery County appraises it as though it still does. That’s sweet if you’re Guniganti – especially when you consider that he owns nearly 2000 acres in the area and all but 217 are classified as Ag & Timber.
But why should sand mines enjoy the Ag/Timber tax break? These are multi-million dollar businesses.
$288 in Tax on 218 Acres
Let’s look at another example of how Guniganti benefitted from an exemption that he didn’t seem to qualify for.
This 218-acre parcel occupies most of the middle of Guniganti’s mine. Though it has some timber on the periphery, approximately 90% of it appears to be used for sand mining.
That parcel has a market value of $439,480, but was appraised at $12,450 because of the agricultural/timber classification.
In this second example, the 2017 tax due on a 218-acre, income-producing property with a market value of nearly half a million dollars is just $287.71. Here’s the actual 2017 tax bill.
Almost 2000 Acres in Two Categories
What about the rest of the mine and the surrounding property which will be used for expansion? As luck would have it – for comparison purposes – the Guniganti Family Trust owns 17 different parcels of land in and around the mine totaling almost 2,000 acres.
Guniganti owns 17 parcels of land in Montgomery County totaling about 2000 acres. For an interactive list, click on the image above.
Most parcels are classified Ag/Timber including approximately 750 acres being mined. However, several are classified as “unimproved rural” and one was “unimproved residential.” Check them for yourself if you have several hours.
This spreadsheet breaks the Guniganti Family Trust properties down into two different categories: Ag/Timber and Other to show the benefits of the ag/timber classification.
The Big Payoff
In 2017, thetaxable value per acre of the ag/timber land was $68 per acre. But the taxable value for the land not receiving any exemption was $3,120 per acre – 46 times more.
The actual tax due for the ag/timber land was $1.83 per acre. But the tax due on other land not receiving the exemption was $102.36 – 56 times more!
Guniganti still enjoys the ag/timber benefit on these properties for the 2018 tax year.
Substantial differences.
Almost 90% of Guniganti’s land is classified as ag/timver. However, he paid seven times more tax on his other land. Thus, you can see the benefits of the exemption.
In total, Guniganti paid $3,189.61 in tax on 1741 acres receiving the ag/timber classification. Those parcels have a market value in excess of $4 million.
Had that property been taxed at the Montgomery County Appraisal District’s opinion of their market value, he would have had to pay about $120,000 more in tax
I still don’t understand how sand mines qualify for Ag/Timber rates when all the ag and timber is long gone. I hope there’s a reasonable explanation. Not all sand mines in Montgomery County receive the ag/timber exemption. But that’s a story for another day.
As always, these represent my opinions on matters of public policy. They are protected by the First Amendment of the United States Constitution and the Anti-SLAPP statute of the great State of Texas.

Today, I discovered similar inconsistencies on the West Fork.
However, even $99/acre is still dirt cheap!
To see the list of who’s classified as what, download this Excel worksheet, West Fork MCAD Classifications.
I still need to investigate this more. Is there a policy in Montgomery County NOT to classify mines as mines? Why are subsurface interests being given away? Did the State do away with the G3 classification?
I’m sure the Montgomery County Appraiser can help us understand why none of the sand mines on the San Jacinto are classified as mines and why half of them receive ag/timber exemptions they apparently don’t qualify for.

East Fork Sand Mine in Montgomery County Appraised as Ag/Timber Land
I wish I could get a deal like this! A cardiologist from Nacogdoches named Dr. Prabhakar R. Guniganti (in a trust set up for his family members) owns virtually all the land used for sand mining adjacent to Kingwood on Caney Creek, White Oak Creek and the East Fork of the San Jacinto.

The guidelines also state that both timber and agricultural land must be used at an intensity comparable to the surrounding area. Additionally, timberland must be used with the intent to produce income from timber and be devoted principally to the production of timber.
$241 in Tax on Ten Acres
I found one 10-acre parcel of Guniganti land that owed a whopping $241.09 in real estate tax for 2017. Deal of the century! It hasn’t had any timber on it for about three years and Montgomery County is still assessing it as timberland for 2018.
See for yourself.
When I clicked on Guniganti’s 10-acre parcel as discussed in Step 2 above, here’s what I found. A little gray box popped up describing the location and size, plus the owner’s name. In this case, Guniganti no longer owns the property himself; he sold it to a trust in his family’s name, Guniganti Family Property Holdings LLC (limited liability corporation). LLCs are a common strategy that land owners use to insulate themselves from liability that may arise from use of the property.

.
Because the Montgomery County appraiser classifies this parcel as “Timber,” the County, emergency services, the hospital, college, and school districts will have to split up a grand total of $241.09.
Nevertheless, Montgomery County taxed the 10 acres at $10,000. At a 2.4109% tax rate, the family trust owed $241.09 on this land in 2017. Here’s the actual tax bill for 2017 from the assessor’s web site:
Of course, the land originally contained timber. Montgomery County appraises it as though it still does. That’s sweet if you’re Guniganti – especially when you consider that he owns nearly 2000 acres in the area and all but 217 are classified as Ag & Timber.
Back in 1966 and 1978, the Texas legislature saw the value of ranch, farm and timberland increasing exponentially. Many family farms and ranches were being taxed out of existence. They didn’t make enough money to pay real estate taxes at the normal market value. So the legislature created special exemptions, first for family farms, and then for corporations and trusts.
Fair enough. We certainly need farms and ranches.
But why should sand mines enjoy the Ag/Timber tax break? These are multi-million dollar businesses.
$288 in Tax on 218 Acres
Let’s look at another example of how Guniganti benefitted from an exemption that he didn’t seem to qualify for.
