Flood Planning Group Lists Recommendations for San Jacinto Basin

10/1/26 – The San Jacinto Regional Flood Planning Group has issued a list of recommendations for the river basin. The draft recommendations are intended for the next statewide flood plan. The 36 recommendations fall in three categories:

  • Legislative (12)
  • Administrative and Regulatory (16)
  • Flood Planning (8)

To see the complete five-page list, click here. It shows more detailed explanations than the summary below.

Legislative Recommendations

Legislative recommendations focus primarily on funding and regulatory authority.

  • L1 – Provide recurring funding for the Flood Infrastructure Fund
  • L2 – Establish state dedicated drainage funding, rather than relying solely on federal funding.
  • L3 – Provide counties with legislative authority to establish drainage utilities and assess drainage fees to assist in the implementation and long-term maintenance and repair of drainage and flood risk reduction projects
  • L4 – Update current statewide building codes with appropriate freeboard or higher flood standards
  • L5 – Establish and fund a levee safety program
  • L6 – Fund Regional Flood Planning Groups between planning cycles
  • L7 – Clarify and expand county regulatory authority for floodplain management, land-use planning, waterway setbacks, permitting, and management of new development in unincorporated areas
  • L8 – Develop and fund repair programs that assist owners of aging dams
  • L9 – Expand funding for flood early warning systems, stream gages, low-water crossing safety improvements, flood-hazard signage, gates, and roadway warning systems
  • L10 – Provide funding and incentives for conservation easements, land conservation, restoration, riparian protection, wetland protection, and landowner stewardship practices in flood-prone areas
  • L11 – Expand or create grant programs for ongoing operations and maintenance of existing flood mitigation, drainage, culvert, and natural infrastructure assets. (Most funding prioritizes new assets.)
  • L12 – Support creation, consolidation, or reorganization of regional flood authorities, flood-control districts, river authority programs, drainage districts where broader regional coordination is needed.

Most of these seem like common sense. Some have been attempted before. For instance, State Rep. Dennis Paul has tried several times to get a river-basin-wide flood control district. However, his bill failed because some local authorities, like Adrian Garcia, fear loss of control.

Regulatory and Administrative Recommendations

These focus mainly on technical and human issues below the state level.

  • A1 – Convert Base Level Engineering (BLE) data into regulatory information or detailed Flood Insurance Rate Maps.
  • A2 – Develop model floodplain ordinances for General Law Cities, i.e., those with populations under 5000.
  • A3 – Promote public education and outreach regarding flood awareness, preparedness, flood-prone areas, and the importance of protecting floodplains.
  • A4 – Educate floodplain managers with low-cost online resources. Many managers in smaller Texas cities and counties have the title without the education.
  • A5 – Develop state incentives for local governments to participate in the FEMA National Flood Insurance Program (NFIP) and Community Rating System (CRS) program. CRS exceeds minimum requirements of NFIP and will help achieve state flood plan requirements.
  • A6 – Establish a publicly available statewide database to track flood-related fatalities
  • A7 – Help smaller jurisdictions prepare flood-grant applications by making the process easier
  • A8 – Model future flood conditions uniformly across the state
  • A9 – Reduce barriers that hinder jurisdictions from partnering to provide regional flood-mitigation solutions.
  • A10 – Promote nature-based solutions, green infrastructure, floodplain preservation, conservation, and hybrid gray/green approaches
  • A11 – Establish statewide building standards for minimum finished-floor elevations above the 500-year floodplain
  • A12 – Incentivize voluntary buyouts for repetitively flooded properties and turn them into green space
  • A13 – Require TXDoT to build roads above the Atlas 14/100-year floodplain or else the pre-existing 500-year floodplain
  • A14 – Improve methods for measuring and documenting flood damages, including uninsured losses, actual flooded structures, financial damages, agricultural damages, and industrial losses, rather than just relying on flood-insurance claims which undercount damages and economic consequences.
  • A15 – Support multi-jurisdictional cooperation at the evaluation, strategy and project levels.
  • A16 – Clarify roles and responsibilities for floodplain management in extraterritorial jurisdiction (ETJ) areas to reduce gaps or overlaps in responsibility for floodplain management, permitting, and drainage standards.

Flood-Planning Recommendations

These aim to help Regional Flood-Planning groups by changing or clarifying the rules under which they operate.

  • F1 – Clarify what constitutes an “emergency.” Regional flood plans must indicate whether a flood-control solution meets and emergency need – without defining emergency. This results in inconsistency across the state.
  • F2 – Simplify requirements for flood-mitigation projects. Don’t automatically eliminate projects missing a benefit/cost analysis (BCA), for instance, during the planning phase if the BCA can be supplied early in the design phase.
  • F3 – Revise scoring criteria for projects that benefit agriculture so they can compete with urban projects
  • F4 – Eliminate bias against lower-population rural areas in scoring of projects
  • F5 – Likewise, eliminate scoring bias against nature-based flood-solutions with stand-alone metrics for their evaluation.
  • F6 – Reduce future flood risk by prioritizing projects that improve FEMA floodplain maps and Base-Flood Elevations.
  • F7 – Improve flood-risk identification by incorporating first-finished-floor elevations and better population-at-risk methods. Many living spaces are elevated above base-flood levels.
  • F8 – Simplify the flood-plan amendment process. Let newly developed projects be amended into regional flood plans between full planning cycles.

Grappling with Unknown Flood Risk

Right now, about 20% of the Texas population lives in a mapped floodplain.

Residential bldgs in Texas 1 % floodplains from state flood plan.
Residential buildings in Texas 1% Annual Chance Floodplains. From 2023 Texas State Flood Plan.

But many people face flood risk they may not realize they have. Current FEMA flood maps resemble a patchwork quilt that incorporates risk studies taken by different groups using different technologies at different points in time. And many streams remain unmapped.

Uniformly updating flood risk maps will likely increase the percentage of the population living in floodplains. In areas with outdated or incomplete maps, residents may face risks revealed by newer rainfall data and hydraulic modeling.

Adopting all these recommendations will go a long way toward protecting the public from future floods and filling the readiness gaps that exist across the river basin and state. Without accurate diagnosis of problems, we will never arrive at viable solutions.

San Jacinto Flood-Planning Group Inventories Readiness in Region

9/30/2026 – As part of the next update of the Texas State Flood Plan, the San Jacinto Regional Flood-Planning Group (SJRFPG) recently inventoried gaps in the the readiness of governmental entities to cope with the next major disaster. They also identified ways to help reduce flood damage.

At the group’s most recent meeting in September, they reviewed two items of interest to everyone in the region:

  1. A draft of Chapter 7 in their plan which covers gaps in:
  • Flood preparedness, response and recovery capabilities for all governmental entities in the region (local communities, counties, state agencies and federal agencies)
  • County Hazard Mitigation Plans
  • Evacuation routes
  • Flood warning Systems
  • Emergency Operations Centers
  • Recovery operations

2. Four pages of Legislative, Regulatory and Administrative Recommendations to reduce flood damage.

I’ll summarize the gaps today and recommendations tomorrow.

Flood-Preparedness and -Response Gaps

The documents contain some eyebrow-raising information in concise, easy-to-read tables and text. For instance, when reviewing flood preparedness and the immediate response after a flood:

  • Galveston, Montgomery and San Jacinto Counties have no publicly listed links to their Hazard Mitigation Plans, even though they have the plans themselves.
  • Of the 11 counties in the region:
  • Only Brazoria had a publicly available emergency action plan
  • Eight have flood-gauge websites where the public can monitor river/bayou levels
  • No county publicly identified flood-preparation teams, suggesting that such programs may be managed internally by emergency management departments without public documentation.
  • Liberty County has no Emergency Operations Center.
  • All counties provide emergency road closure information, but most don’t have dedicated websites for that purpose.
  • The availability of high-water-rescue resources was described as only “moderately high.”
  • No counties maintained publicly available lists of flood shelters.
  • Comprehensive information regarding the number and location of resource distribution centers, emergency supplies and shelter capacities is not publicly available.

Flood-Recovery Gaps

FEMA defines flood recovery as actions taken after a flood necessary to return to pre-flood conditions. It includes activities such as:

  • Damage Assessment
  • Debris Removal
  • Housing Solutions
  • Clothing Distribution Locations
  • First Aid
  • Buyouts
  • Disaster Event Records

In the San Jacinto Region, data available for flood recovery was considerably more limited than for preparedness and response.

  • No county in the San Jacinto River Basin offered publicly facing information identifying flood-damage assessment teams.
  • Five of the 11 counties offer publicly available information on the cost of debris removal, procurement records and awarded contracts – usually for federally funded recovery activities.
  • Only Brazoria, Harris and Fort Bend Counties offered housing rehab info.
  • No county offered a publicly available database for aid distribution, which is often handled through disaster relief agencies such as the Red Cross.
  • Buyouts reduce the threat of repetitive flood losses, but due to the sensitivity of such programs, public information is limited. That limits the ability to assess the extent and success of such programs across the state.
  • All counties maintain disaster event records. They usually live on the county website of within Hazard Mitigation Plans.

Get Involved

The SJRFPG sees “a significant gap in centralized and transparent reporting of recovery resources.” That makes comprehensive regional recover assessments challenging.” That gaps do not necessarily indicated a lack of capability, but rather reflect limitations in publicly accessible documentation. And that could affect your family’s safety.

Community input remains a critical component in shaping a more resilient future for the San Jacinto region. However, the group no longer offers the ability to attend its meetings online due to recurring technical problems. So monitor their website closely for upcoming meetings/locations/agendas.

Remnants of Hurricane Polo Bringing Heavy Rains to Texas

9/29/26 – The remnants of Pacific Hurricane Polo will bring heavy rain to Texas in the next four days and produce a slight-to-moderate risk of flash flooding. The heaviest rainfall will likely focus on areas to the west of Houston. However, Houston area residents should remain alert for changes in the forecast.

Current Location and Conditions

Earlier today, Polo made landfall in western Mexico in Sonora.

National Weather Service predicts Polo will dump 4-6 inches of rain across a broad area in southwest Mexico.

The National Hurricane Center says that heavy rainfall associated with Polo will impact the southern and central portions of Sonora today. This rainfall will likely produce life-threatening flooding and mudslides, especially in areas of steep terrain.

Moisture from Polo will support heavy rainfall and flooding potential across the Southwest U.S. into the Southern High Plains today into early Wednesday.

Multiple news reports tonight warned of flash flooding and a possible dam failure in New Mexico that has already prompted evacuations.

Forecast

While the storm is currently headed more toward New Mexico and far west Texas, forecasters predict it will angle towards central Texas in coming days and combine with an area of low pressure predicted to form in the Gulf later this week.

Pivotal Weather shows a wide swath of 5-6 inches of rainfall across areas west of Houston in the next 5 days. Some areas could experience intense rainfall at high hourly rates that produces flash flooding.

The Houston/Galveston office of the National Weather Service predicts the probability of excessive rainfall leading to flash flooding in the Houston area in the next three days is marginal (at least 5%) to slight (at least 15%).

Four days from now, they show the Houston area in the marginal category. All of the “slight risk” has shifted west toward San Antonio.

Much Needed Rainfall

Jeff Lindner, Harris County’s meteorologist, says the rain should hit this area later this week and possibly into the weekend. He also characterized it as “much needed.”

The U.S. Drought Monitor currently shows much of the Houston area as abnormally dry with parts of the region slipping into moderate drought.

As Polo moves inland, it will pull tropical moisture off the western Gulf which will combine with a mid- and high-level moisture from the Pacific.

Lindner says that a second tropical system (Rachel) forming off the southwest coast of Mexico will also shed moisture into a trough forming over the southern plains late this week and this weekend. See this revealing IR Satellite Loop for Atlantic/EPAC Combo on Tropical Tidbits.

Lindner predicts a swath of very heavy to excessive rainfall from generally near or west of the I-35 corridor. Rainfall rates of several inches per hour may induce rapid onset flash flooding in this area even with very dry ground conditions and dry creeks/rivers. 

“Locally, moisture from the Gulf will help produce scattered showers and thunderstorms as early as Wednesday with increasing chances into late week.”

Jeff Lindner, Harris County Meteorologist

Lindner also worries that steering currents over central Texas could force the axis of heavier rains closer or into our area, where a low pressure trough expected to form off our coast this weekend may result in another rainfall maximum near and offshore.

Any flood potential with  the current forecasted amounts would be street flooding, according to Lindner.
