Eduardo Valerio
Assistant Director, Stormwater Operations 

The Stormwater Operations Division provides the following services and programs to all citizens and business districts of Dallas. Please see the listings below.

Floodplain & Drainage Management

Floodplain Management provides studies and mapping to both public and private developments to ensure that all development within the floodplain is designed to reduce the risk of flooding.  It prohibits development in areas that are prone to flooding unless all applicable City, State and Federal floodplain related permits are issued.   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 the FEMA Community Rating System program, Dallas property owners located within floodplain areas 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 and preliminary design of projects that are placed on the needs inventory for future capital program funding.

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, and retention/detention basins.  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.
