NCTCOG seeks to connect people, places, and programs to achieve safe waterways with clean water within a regional ecosystem framework of green watersheds. This flyer presents some of these efforts occurring in the Trinity River Headwaters watershed. Opportunities for Watershed Protection Watershed protection is a collaborative effort that must involve all watershed stakeholders. At NCTCOG’s 2010 series of watershed meetings, participants of the Trinity River Headwaters watershed meeting identified 50 opportunities for protecting watersheds that drain to the Trinity River. These opportunities were then organized by NCTCOG’s goals of connecting people, places, and programs. The comments indicated equal opportunity for connecting people (32%), connecting programs (32%), and connecting places (36%). Nearly 35% of the comments cited an opportunity for more coordination and better integration of programs. For instance, more coordination is needed among downstream and upstream agencies, as well as to share needs and desires and to coordinate better on stormwater issues. There is also an opportunity to better integrate water quality and quantity efforts and TMDL implementation plan measures into stormwater programs. Convening watershed stakeholders at meetings, participating in the development of an implementation plan to reduce bacteria loads, collaboratively managing stormwater, and continuing and expanding Trinity River COMMON VISION efforts, are all ways in which these opportunities can be made a reality. Implementing a Total Maximum Daily Load for Bacteria State studies indicate that the headwaters of the Trinity River, also known as the Upper Trinity (Segment 0805), are impacted by high bacteria levels along a section that runs from the confluence of the Trinity’s West Fork and Elm Fork in Dallas, downstream to Five Mile Creek and its confluence with the Trinity. Although the City of Dallas has most of the land within this segment’s watershed, University Park, Highland Park, and Cockrell Hill are also impacted. See the map on the inside page for location details. When pollutants like bacteria reach the levels found in the Trinity, the state, as part of the Clean Water Act, establishes a Total Maximum Daily Load for that particular water body or stream segment. Referred to as a TMDL, it is the maximum amount or load of a pollutant that a water body can receive and still maintain its uses (recreation, fish/wildlife habitat, etc.). The load is then allocated among the sources of pollution within the watershed and measures to reduce pollutant loads are developed as necessary. These measures are combined into an Implementation Plan, or I‐Plan, and developing them is a group effort, requiring participation from cities, businesses, and interest groups. For more information on how to become a partner in this process, visit www.nctcog.org/envir/SEEclean/wq/tmdl/ index.asp for more information and a schedule of meetings. Integrating Stormwater Management and TMDL Implementation The Trinity River Headwaters watershed is so called because it begins the main stem of the Trinity River, just past the junction of the Elm and the West Forks of the Trinity. This watershed also receives the drainage from White Rock Lake. Although more than a dozen cities impact this watershed, only four are predominantly contained within it and most participate in NCTCOG’s Regional Stormwater Management Program. The City of Dallas occupies the majority of the watershed, so its stormwater program and best management practices have the greatest influence on reducing pollutants from runoff. This segment of the Trinity River is listed as impaired for bacteria and is currently in the process of developing a TMDL I‐Plan. Being the largest entity in the region, it isn’t surprising that the City of Dallas has a well staffed program of 40 to 50 people. Sue Alvarez, Senior Program Manager, directs the activities of these staff as well as coordinates the stormwater‐related activities of 11 other city departments. Her department staff focuses on water quality sampling, construction, industrial compliance and enforcement, public outreach, managing the stormwater utility, and addressing customer service calls. As part of addressing the upcoming bacteria TMDL issues, Dallas is planning to implement additional sampling on the Trinity River. However, they currently also have a number of activities already in place such as illicit discharge detection programs and pet waste outreach campaigns to complement newer efforts. Dallas’ stormwater program is funded by a utility fee that is based on land use category. They are currently revising it to base it on impervious area instead which they feel will be more fair.

Comprehensive Solutions for Protecting Water Quality The Trinity River Headwaters watershed will continue to experience significant development and redevelopment. If not managed properly, construction and development activities could negatively impact stream, river, and lake health. NCTCOG’s integrated Stormwater Management (iSWM) Program provides comprehensive solutions for local governments to help protect water quality and streambank health, and to avoid downstream flooding impacts associated with development. Emphasis is placed on integrated Site Design Practices that provide a green approach to stormwater management, which can be supplemented with structural stormwater controls to meet all required project objectives. iSWM also provides methods to ensure that water resources are protected during the active construction phase of development. Dallas and Plano are among the cities with significant land area within the Trinity River Headwaters watershed that are working on implementation of iSWM. Dallas currently offers iSWM as a voluntary approach for developers and Plano is in the process of considering iSWM implementation. iSWM applied along with local city planning and development ordinances offers a comprehensive and effective approach to stormwater management. For more information about iSWM, visit http://iswm.nctcog.org. Achieving a Safe, Clean, Natural, Enjoyable, and Diverse Trinity River Corridor The Trinity River COMMON VISION Program remains a leading example of cooperation among all levels of government. Important local projects like the Dallas Floodway Extension Project and the Trinity Trails System have coordinated with our regional efforts for many years. They are significant examples of the creativity and initiative being shown all along the river in this watershed area. The program's objective for the Trinity River is to achieve a Safe, Clean, Natural, Enjoyable and Diverse river corridor. For over twenty years, NCTCOG and participating communities have been developing a vision of what the river should be, now and into the future. We are partnering with the U.S. Army Corps of Engineers on behalf local governments in the successful Upper Trinity River Feasibility Study. Our partnership has produced many innovative programs, including a Corridor Development Certificate (CDC) Process, improvements in engineering, and project plans pursuing diverse multi‐objective alternatives throughout the corridor. We know the value of the program is only partly in what we have accomplished so far. Instead, a larger significance is putting into place an ongoing process to address the challenges of protecting our water resources as the region continues to grow and develop. Efforts to update mapping and modeling tools for decision makers are going to be exciting areas of work in the upcoming years. Maintenance and fine‐tuning of the CDC process will also be something for our partners to work on; finding ways to pass on the lessons learned to new areas of the Trinity Basin.
