In response to the devastating July 2025 Hill Country floods, the Texas Legislature passed several bills aimed at improving Texas' preparedness for future flood events, including Senate Bill 3 (SB 3), which relates to outdoor warning sirens in flash flood-prone areas. Governor Abbott signed SB 3 into law on September 5, 2025.
SB 3 directs the Texas Water Development Board (TWDB) to assess the 30 counties included in the disaster declaration issued by the Governor in July 2025 to identify flash flood-prone areas with a history of consistent or severe flooding where outdoor warning sirens are warranted.
The bill requires:
- the appropriate municipality or county within those areas identified by the TWDB to install, maintain, and operate an outdoor warning siren system—which is defined to include all components essential to the system's functionality,
- the TWDB to facilitate the development of best management practices and guidance for the operation of outdoor warning sirens, and
- the TWDB to develop rules relating to requirements for outdoor warning systems in flash flood-prone areas.
SB 3 also requires the Office of the Governor to establish and administer a grant program to assist municipalities, counties, and other governmental entities with the costs of installing outdoor warning sirens. In November 2025, the Office of the Governor delegated this responsibility to the TWDB. The grant program will be developed in the weeks and months to come, and as details regarding the program become available, they will be added to this page.
Senate Bill 5, also passed by the Texas Legislature and signed by the Governor on September 18, 2025, appropriated funding from the state's economic stabilization fund to the Office of the Governor for a variety of purposes related to disaster relief and preparedness. There is $50 million in allocated funding for grants to assist counties, municipalities, and other local governmental entities within the 30 counties identified by the disaster declaration to establish and implement a system of flood warning sirens and flood gages and to purchase other related equipment. In November 2025, the Office of the Governor entered into an agreement with the TWDB to administer the grant program outlined in SB 3.
The TWDB is working to implement SB 3 on a highly accelerated timeline, and updates will be made to this webpage as more resources and information become available.

Funding eligibility is limited to county governments within the disaster declaration issued by the Governor in July 2025.
This grant funding is intended to support the installation of outdoor warning siren systems, including flood gages and all other components essential to the function of the system. These essential components can include physical infrastructure, such as rain gages, flood gages, and solar panels, as well as non-physical components such as education, outreach, and training.
The county may work with municipalities and other governmental entities to determine necessary projects and project sponsors, to install the required outdoor warning siren systems, and to transfer the funds to do so. This should be done through a written agreement.
Senate Bill 3 does not allow for maintenance or equipment upkeep as part of the siren grant program, so either the county or another entity that contracts with the county will be responsible for those expenses.
The Senate Bill 3 Sample Resolution serves as an example resolution. Counties may use their own form or template for the resolution and are not required to use this form.
Counties should include substantially similar content in order to authorize a representative to execute the grant agreement and accept the funds on the County's behalf. The TWDB's governing Board authorized an initial grant amount of $1million and authorized the Executive Administrator to increase that amount by $250,000 if needed. The sample resolution includes authorization for the full $1.25 million and authorization for certain amendments as an example for Counties to use if they so choose. If they would prefer to require Commissioner's Court action for amendments or increases, they could do so.
No, project plans submitted to the TWDB do not need to be certified by a P.E.
Because of the expedited nature of these funds, the TWDB may reduce the amount of financial assistance available under the grant agreement if the County fails to submit approvable Project Plans for the full $1,000,000 initial amount awarded under this Agreement by December 31, 2026.
Yes, counties will be able to request reimbursements for eligible costs incurred after September 5, 2025, the effective date of Senate Bill 3.
The TWDB may enter into a grant agreement with each county for a maximum initial amount of $1 million with an allowance to increase that amount by $250,000; any additional increases would require approval by the TWDB's governing Board.
Resources
- Senate Bill 3 (SB 3) - SB 3 directs the TWDB to 1) assess the 30 counties included in the July 2025 disaster declaration to identify flash flood-prone areas, 2) facilitate the development of best management practices and guidance for the operation of outdoor warning sirens, and 3) develop rules relating to requirements for outdoor warning systems in flash flood-prone areas. The TWDB is also responsible for the development of the grant program described in SB 3, as the Office of the Governor has delegated this responsibility to the agency.
- Senate Bill 5 (SB 5) - SB 5 appropriated $50 million in funding from the state's economic stabilization fund to the Office of the Governor for grants to assist entities within the 30 counties identified by the disaster declaration. This funding must be used to establish and implement a system of flood warning sirens and flood gages and to purchase other related equipment. The Office of the Governor has entered into an agreement with the TWDB that empowers the agency to administer these grants.
- July 2025 Flood Disaster Proclamation - On July 22, 2025, the Governor issued a disaster proclamation for 30 counties impacted by flooding in early July 2025. These are the same counties impacted by SB 3.
- Senate Bill 3 Implementation Board Memo - On December 16, 2025, the TWDB's Board was briefed on the SB 3 implementation plan.

- Senate Bill 3 Sample Resolution - Each county included in the July 2025 Flood Disaster Proclamation is required to submit a resolution from its Commissioners Court authorizing acceptance of outdoor warning siren system funding and approval to enter into an agreement with the TWDB. The form provided serves as an example resolution. Counties may use their own form or template for the resolution and are not required to use this form. Counties should include substantially similar content to authorize a representative to execute the grant agreement and accept the funds on the County's behalf. The TWDB authorized an initial grant amount up to $1 million and allowance for an additional $250,000 with approval from the Executive Administrator. The sample resolution authorizes the full $1.25 million, and for certain amendments, as an example for Counties that choose to authorize the full amount now. Alternatively, if they would prefer to require Commissioners Court action for any amendments or increases, they could do so.
- Flood Early Warning Systems Guidance - Effective Flood Early Warning Systems (FEWS) are essential to reducing flood impacts on Texas communities. The TWDB developed this guidance document to provide stakeholders with a resource to support FEWS planning, financing, deployment, and management.
- Alternative Flood Early Warning Systems Guide - This guide was developed to provide communities with information on how to select, install, and operate a commercially available and scalable low-cost flood sensor (LCFS) flood warning system that provides real-time flood alert communications at roadways.
