Upper Trinity River Transportation and Stormwater Infrastructure Project

Technical Advisory Group Meeting - May 2025 (Exact Date/Time: TBD)

The goal of the TSI study is to dissolve silos in the stormwater, transportation, and environmental fields, enabling proactive planning of infrastructure that reduces stormwater runoff/flooding impacts, increases transportation safety, and incorporates environmental elements such as green infrastructure. The TSI Technical Advisory Group provides input to the TSI study team regarding policy, outreach, data, and challenges that communities face.

County Watershed Workshop - May 2025 (Exact Date/Time: TBD)

This workshop will focus on risk, development, recommendations, and the Texas Water Code, specifically regarding enforcement in floodplains. There will also be discussions with stormwater professionals on model regulations and minimum control measures related to post-construction efforts. 

The Technical Advisory Group (TAG) 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 TSI study.
