Drainage Systems in Acadiana
Understanding Drainage Systems in Lafayette
What Every Landowner and Developer Should Know
Whether you’re building a custom home, developing a few lots, or planning a subdivision, understanding how drainage systems work is critical to protecting your investment.
Here’s a breakdown of the most common drainage systems used in Lafayette—and how we approach them as builders.
Why Drainage Matters So Much in Lafayette
With flat terrain, heavy rainfall, and a high water table, Lafayette requires thoughtful drainage planning on every project.
Done right, drainage:
Prevents flooding on-site and downstream
Protects foundations and roadways
Keeps lots buildable and marketable
Done wrong, it leads to:
Standing water
Costly rework
Unhappy homeowners
That’s why we treat drainage as a core part of development.
1. Open Ditches & Swales
Open ditches and swales are the most common drainage system used throughout Acadiana.
How They Work:
Water is directed across the surface into shallow, graded channels that carry runoff away from lots and roadways.
Why They’re Used:
Cost-effective
Simple to maintain
Well-suited for flat terrain
What Matters Most:
Proper slope and grading
Correct elevation of lots vs. ditch
Consistent outfall direction
2. Culverts & Underground Drainage Pipes
Culverts and underground piping systems are used to move water efficiently beneath roads, driveways, and other obstructions.
How They Work:
Water flows through pipes (typically concrete or HDPE) to connect ditches and drainage systems across the site.
Where You’ll See Them:
Under driveways
Beneath road crossings
Connecting swales to larger systems
What Matters Most:
Proper pipe sizing
Correct installation elevation
Long-term durability
3. Detention & Retention Ponds
Most modern developments require some form of stormwater storage—and that’s where detention and retention ponds come in.
How They Work:
Detention ponds temporarily hold water and release it slowly
Retention ponds hold water permanently
Why They’re Important:
Reduce downstream flooding
Meet local drainage regulations
Manage runoff from roads and roofs
What Matters Most:
Proper sizing and engineering
Controlled outflow
Integration into the overall site design
4. Curb & Gutter Drainage Systems
In higher-density or more urban-style developments, curb and gutter systems replace traditional ditches.
How They Work:
Water flows along the street into curb inlets (or commonly called catch basin), which connect to underground storm sewer systems.
Why They’re Used:
Cleaner, more finished look
Maximizes usable lot space
Common in tighter developments
What Matters Most:
Proper catch basin spacing
Adequate pipe capacity
Coordination with street elevations
While more expensive, this system can elevate the overall feel of a neighborhood.
Choosing the Right System for Your Property
Not every drainage solution fits every piece of land.
The right system depends on:
Property size and layout
Soil conditions
Elevation and flood zone
Access to existing drainage infrastructure
Budget and development goals
