City Drainage Responsibilities

Drainage Projects

To keep water moving through Southlake, City of Southlake engineers are always considering how water will impact public lands. When the City engineers see a potential issue, they make recommendations to the City Council to invest public dollars into proper drainage. These investments have helped re-distribute stormwater, but there is always more work to be done. Learn about some of our planned projects here.

Street Sweeping

The City also conducts street sweeping as a best practice to maintain our quality infrastructure. This helps by removing debris and pollutants and keeping them from entering our stormwater system and drainageways and ultimately into creeks, rivers and larger bodies of water.

Storm Damage Response

The City of Southlake Streets and Drainage Team stands ready to respond to storm damage. Our priority is to clear pathways for first responders before goad clearance operations begin. However, City crews are not legally allowed to utilize public resources for cleaning private property. Homeowners and homeowner associations (HOAs) are responsible for their property.

Floodplains and Permitting

A floodplain is any land area susceptible to flooding. This can happen by the collection, pooling and flowing of water from any source during the course of natural events. Floodplains may be classified as FEMA Special Flood Hazard Areas (SFHA) and are located in a 100-year flood zone. The term "100-year flood zone" refers to an area that has a 1% chance of being flooded each year.

A special floodplain permit is required for new development construction within a floodplain. If this applies to your situation, please complete the City's Floodplain Development Application. Keep in mind that development within a FEMA regulated floodplain may also require a separate submission to that agency.

The City's interactive map system shows the 100 year and 500 year flood zones. To access these maps, click the map and scroll down to the "Environmental" tab. Click it "on" to display the flood zone layers (purpose and green). You can turn the two flood zones on and off as needed.
