Trinity Watershed Management

The Trinity Watershed Management department encompasses three divisions and a project that provide services to all citizens and business districts of Dallas.  Please see the listings below.

Flood Con​trol and City-Wide Interior Drainage – Dhruv Pandya, Assistant Director

Flood protection is the primary service provided by the Flood Control Division, and is provided through the maintenance and operation of the Dallas Floodway Project consisting of pump stations, pressure sewers, levees, flood walls, drainage/closure structures, channels, floodway and miscellaneous facilities.  Maintenance of the Dallas Floodway System must be performed in accordance with U.S. Army Corps of Engineers (Corps) regulations.  Other duties include maintenance of Flooded Roadway Warning System (FRWS), flood gauge sites, retention/detention basins, and Civil Defense sirens.  Additional duties include removal of blockages on City-owned creeks/channels (except creeks and channels located in Parks), storm sewers, and responds to inclement weather emergencies such as snow/ice, wind storms and street flooding.

Floodplain & ​Drainage Management​ – Susan Alvarez, P.E., Assistant Director

 Floodplain and Drainage Management provides studies and mapping to ensure that public infrastructure and private developments are designed to avoid flooding. It encourages the preservation of natural streams and green space and prohibits development in areas that are prone to flood, as required by state law unless an acceptable floodplain permit is issued. By regulating the floodplain and participating in FEMA programs, Dallas property owners qualify for a 25% discount on their flood insurance (please speak to your insurance agent or FEMA to learn more about the discount and how it might apply to your insurance policy.) Additionally, this division is responsible for the planning, design, construction, administration and management of the drainage infrastructure in Capital Bond programs.

Stormwater Management – Milton Brooks, P.E., Interim Assistant Director

Stormwater Management is a division designed to educate the public, school children, and businesses (construction and other industries) on stormwater pollution prevention related issues and permitting requirements respective to protecting our creeks, lakes, and rivers to improve our lifestyle, natural environment, and water resource use. In addition, the Program includes enforcement inspections to ensure compliance with federal, state, and local stormwater regulations as well as water sampling to detect and correct water pollution in Dallas’ lakes and creeks and the Trinity River.
