 The Localized Flood Control Program constructs localized flood control improvements to protect lives and property.
Austin's primary drainage system is our creeks and lakes. The secondary drainage system is approximately 400 miles of pipes and channels which convey storm water to the creeks and lakes. When part of the secondary drainage system is overwhelmed, "localized flooding" is the result. The secondary drainage system consists of:
- Manholes
- Minor channels
- Roadside ditches
- Culverts
- Over 18,000 curb inlets
- Storm drainpipes (ranging in diameter from 6" to 8')
What We Do
- Localized Flooding Assessment
- Project Planning, Design, and Implementation
- Field Engineering
- Inspections (customer complaints, ponds, FEMA crossings)
- Utility Coordination
Level of Services Provided
Flooding situations that immediately threaten lives and property are always top priority. Please call (512) 974-3355 if you see major obstructions such as downed trees or telephone poles in a creek, or you see a blocked culvert or bridge opening. For other localized flooding problems, the runoff (overland flow of stormwater) type must be determined first:
- Private Runoff: Property owners are responsible for runoff from private property or between private properties.
- Public Runoff:The City of Austin maintains public right-of-ways and drainage easements including: storm drains, inlets, manholes, discharge headwalls, creeks, city ponds, channels, swales, roadside ditches and culverts, and culverts under roads.
Once a problem area has been determined to be from a public right-of-way or drainage easement, it is then ranked for upgrading based on the following priority scale (limited to available funding):
- Building flooding
- Yard flooding
- Street flooding
- Standing water
