Upper Trinity River Transportation and Stormwater Infrastructure Project
Recent flood events in Texas have brought to the attention of the State the need for more comprehensive planning in urban areas. This is particularly important in the upstream portions of the Trinity watershed where urban growth and development is expected to continue and where unmanaged growth will have strongly negative consequences on downstream communities like Dallas and Fort Worth. The North Central Texas region has a distinct window of opportunity to proactively engage in comprehensive planning efforts that integrate its transportation, environmental and stormwater needs to address the health, safety, and welfare concerns of the region while helping local governments manage their growth and development in a cost-effective manner.
The Transportation and Stormwater Infrastructure (TSI) study will identify projects to reduce future flood risk and potential funding sources to implement those projects. The study also will generate:
- Maps and models of future flood risk
- Policy recommendations related to development and floodplain management
The study is expected to conclude in 2026.

The Technical Advisory Group was formed to provide input to the TSI Project team regarding policy, outreach, data, and challenges that communities face. The goals of the advisory group are as follows:
- Use technical and local knowledge to provide policy guidance and recommendations that should be developed or updated to the project team.
- Provide technical input to identify gaps in the existing future planning landscape and share ideas of innovation.
- Give feedback on data and modeling needs for the study area.
- Provide guidance that helps project team produce products that benefit the intended communities and stakeholders.
- Act as a link between project team and community leadership.
- Support and represent the interests of stakeholders within a larger context of flood mitigation.
- Collaborate with TSI project to support shared goals in local communities and increase the project's visibility, both internally and externally.
- Provide advice on overall approach best practices, lessons learned that will reduce the impact of flooding

Map Your Watershed! allows communities to identify infrastructure and environmental features that face frequent flooding or whose presence could mitigate flooding. These features could include roads that are covered with water during heavy rain; green infrastructure, such as detention ponds that retain stormwater; or open space planned for enhancement, such as recreation trails. Please identify any other features you believe are relevant to the Integrated Transportation and Stormwater Infrastructure study.
