Several national comprehensive studies have indicated that stormwater runoff pollution within highly urbanized areas is a major contributor to water pollution in the United States.
As rain falls and stormwater runoff collects and travels over urban lands, it picks up and carries pollutants through municipal separate storm sewer systems (MS4s) and ultimately on to streams, lakes, rivers and other water sources impairing water quality. If you have stormwater concerns, please call the Stormwater Runoff Hotline at 214-644-8999.
Stormwater Permitting Program
Under the authority of the Clean Water Act, the Environmental Protection Agency (EPA) developed a storm water permitting program with the goal of significantly reducing the pollution source.
The City of Lucas has been designated by the EPA as an urbanized area and therefore must make application to discharge storm water to waters of the United States.

The iSWM™ Program for Construction and Development (Manual) is a cooperative initiative that assists cities and counties to achieve their goals of water quality protection, streambank protection, and flood mitigation, while also helping communities meet their construction and post-construction obligations under state stormwater permits.
Development and redevelopment by their nature increase the amount of imperviousness in our surrounding environment. This increased imperviousness translates into loss of natural areas, more sources for pollution in runoff, and heightened flooding risks. To help mitigate these impacts, more than 60 local governments are cooperating to proactively create sound stormwater management guidance for the region through the integrated Stormwater Management (iSWM) Program.
The iSWM Program is comprised of four types of documentation and tools. These are used to complement each other and to support the development process.
The iSWM Criteria Manual for Site Development and Construction contains criteria that cities and counties may use as a component of their stormwater management related development regulations. The Manual contains criteria to address and manage the water quality, streambank protection, storm water conveyance, and flood control issues associated with development and redevelopment. The criteria may be customized by local governments to meet specific local needs, which provides a flexible approach to implementation.
The iSWM Online Technical Manual contains iSWM Technical Guidance documents that will be maintained by NCTCOG on the web. This module is referenced by the iSWM Criteria Manual and provides the technical details to meet the requirements established by each community in their iSWM Manual.
iSWM Program Guidance contains documents that guide local governments in adopting and implementing the iSWM Program and in developing a comprehensive stormwater management program.
Recent materials have been developed for local government implementation of iSWM. Additional information is being developed and will be posted. For more information, please email [email protected] or call 817-695-9210.
The design manual for construction is also intended to assist public and private entities in compliance with the Texas pollutant discharge elimination system general permit for construction storm water runoff, TXR150000, issued by the Texas Commission on Environmental Quality.
